referring now particularly to the drawings which show views of exemplary versions of some of the templates that are contemplated by this invention . the drawings also illustrate how the above mentioned disadvantages have been overcome . it should be noted that the disclosed invention is disposed to versions in various sizes , shapes , contents , and forms . therefore , the versions described herein are provided with the understanding that the present disclosure is intended as illustrative and is not intended to limit the invention to the versions described herein . fire barriers are often , but not necessarily , constructed of three - layers ; a thick insulation layer , an intumescent layer , and a protective cloth layer where the protective cloth is used to prevent the more susceptible insulation blanket from suffering physical damage , such as tearing . one preferred method of constructing the multi - dimensional fire barriers of this invention is to use the three - layer construction method , although it should be understood that many other methods and materials may also be used . many variations of structural multi - dimensional expansion joints exist . fig2 illustrates the basic one - dimensional , straight expansion joint and three multi - dimensional expansion joints . an example of one preferred version of the multi - dimensional fire barriers taught herein is an l - shaped fire barrier that fits into corner expansion joints . to construct the three - layered l - shaped fire barrier , protective cloth , which is one of the three - layers , is cut according to the template illustrated in fig1 and then stitched along the “ sew line .” this assembly method produces a protective cloth jacket that fits neatly into a 90 degree junction expansion joint with tearing . protective cloth , although strong and somewhat flexible , is often rigid enough to be prone to tearing when stressed by bending , such as by being forced to achieve a corner shape . additionally , if the relatively thick protective cloth is folded to fit a corner without first shaping the cloth , as taught herein , an unacceptable bulky product will be produced . however , when the protective cloth is cut , folded , and seamed according to the pattern provided by the principles of this invention a custom - shaped multi - dimension l - shaped fire barrier without excess bulk is produced . moreover , this unique method of shaping the protective cloth of the barrier eliminates the stresses on and potential for tearing of the protective cloth . the protective cloth may be seamed by stitching using a high - temperature thread , such as filamentous fused silica , for example . the l - shaped protective cloth cut , folded , and sewn according to this method is now ready to be used in the construction of a 90 degree expansion joint fire barrier unit . the protective cloth part , thus shaped , will be referred to as the first part of the l - shaped barrier . the second part of the l - shaped barrier as shown in fig2 , comprises the other two layers of the three - layer construction . in this example , a layer of intumescent material 20 strip - layers are positioned on insulation blanket layer 40 , as shown . the two layers may be connected by stitching using high - temperature thread 22 at this point or they may be stitched together with the protective cloth after the following step . fig3 is a perspective view looking down on and into a multi - dimension fire barrier preformed and ready to be installed in a 90 degree expansion joint . as can be seen , the insulation blanket and the intumescent strips , as shown in fig2 have been placed into the l - shaped protective blanket . the three - layers are affixed together at this point by sewing or by any other desired fixation means , such as by stapling or by using pins and washers as illustrated in fig3 . as can be seen , the more easily damaged insulation blanket and the intumescent strips are supported and protected by the shaped layer of protective cloth . the intumescent material , which expands when a certain high - temperature is reached , is functionally positioned to provide the maximum amount of protection against the penetration of heat , flame , or smoke . the intumescent expansion prevents the passage of heat , flame , or smoke though openings that may have existed before being blocked by the swollen intumescent . as is shown in fig4 , the stitching that attaches the intumescent material to the blanket goes through the intumescent strips , the blanket , and the protective cloth , so that all three - layers are attached together to provide a unitary functional unit . once the l - shaped fire barrier is situated in a 90 degree expansion joint it may be attached to the structural unit in a variety of ways , such as by riveting the fold - out portions of the protective blanket ( as shown in fig3 ) to the top of the structure . another expansion joint configuration that occurs frequently is the t - shaped expansion joint which occurs when three structures meet , such as the convergence of three walls . fig5 shows the base part of a custom sized and styled t - shaped fire barrier . also illustrated in fig5 is the three - layer construction that was also used in the l - shaped fire barrier . it must again be pointed out , however , that other materials and other constructions may be used in the manufacture of a fire barrier . the novelty of this invention resides mainly in providing multi - dimensional fire barrier structures regardless of the materials used to make the structures , and in teaching the methods of making the custom - fit and custom - sized multi - dimensional fire barriers , where the fire barriers are produced as ready to install one - piece units , or if desired , may be provided unassembled to be assembled on - site . as shown in fig5 , strips of intumescent material 20 are functionally positioned on the surface of insulation blanket 40 , which in turn is functionally positioned on protective cloth 30 . intumescent layer 20 , insulation blanket 40 , and protective cloth 30 are fixedly attached together to form an integral unit . in this example , the fixation is accomplished by stitching , as was shown in fig4 , using a high - temperature thread , although the fixation may be accomplished by any other fixation means , including staples and adhesive , for example . to prepare unfolded part 1 ( i . e ., the base of the barrier ), as illustrated in fig5 , for its union with part 2 ( i . e ., the attachment part ) as illustrated in fig7 , the top and bottom end of part 1 ( the base ) are folded toward each other about the two fold lines shown in fig5 . shown situated on each side of the “ t ” flap of the base , fig5 , are two extensions of insulator blanket 40 . the inner edges of the two extensions of the insulator blanket , that is , the edges that border each side of the “ t ” flap , are constructed to be physically separate from the “ t ” flap ( i . e ., cut loose from the “ t ” flap ) so that the “ t ” flap can be maintained in its folded out position while the two insulator blanket extensions along with the protective cloth extensions ( denoted pc ) are folded up , as is shown in fig6 . fig7 is a plan view looking down onto an unfolded second part ( the attachment part ) of a t - shaped multi - dimension fire barrier . to prepare part 2 ( the attachment part ) for connection to part 1 ( the base section ), the two side walls of part 2 are folded up towards each other at the fold lines shown in the figure . once this is accomplished , part 2 is positioned so that the “ t ” flap support part of the base part is placed under the “ t ” flap of the attachment part . with part 2 ( the attachment part ) so positioned , the folded - up side walls of part 2 ( the base part ) provide side walls for the “ t ” flap extension of the t - shaped fire barrier . finally , the fold - out portions are folded out to be used for attaching the fire barrier to the structure parts of the expansion joint . fig7 a , a perspective view of the “ t ” shaped expansion fire barrier ready for installation , illustrates the completely fabricated fire barrier with the addition of protective metal screening , which can be shipped directly to the construction site to be positioned in place . the barrier is permanently attached to the joint structure by any effective attachment means , such as by the use of rivets . the figure shows the use of clamps as the means to attach the barrier to the model expansion structure . another common multi - dimensional expansion joint configuration is that of the 4 - way or cross - shaped joint . this joint occurs where four structures converge , such as the convergence of four walls , for example . how to make a fire barrier custom styled and sized for any 4 - way junction is shown in fig8 - 10 . fig8 shows the base part of a 4 - way fire barrier . as in the other examples , this example also employs three - layer construction , where the layers comprise an intumescent strip layer positioned on a layer of insulation material , which in turn is positioned on a layer of protective cloth . the three - layers are connected together by stitching ( as shown in fig4 ), where the stitching is accomplished using high - temperature thread . the design of the base part of the 4 - way fire barrier uses the principals of the t - shaped fire barrier . in fact , the construct of the “ t ” flap end of the base part of the t - shaped fire barrier is simply followed on the two opposing ends of the base part of the 4 - way fire barrier instead of on only one end of the base as is done in the t - shaped fire barrier . situated on each side of the two 4 - way flaps of the protective cloth base of the 4 - way barrier are two extensions of insulator blanket 40 . the inner edges of the two extensions of the insulator blanket , that is , the edges that border each side of the “ t ” flap , are constructed to be physically separate from the “ t ” flap , so that the “ t ” flap is kept open flat while the two insulator blanket extensions along with the protective cloth extensions ( denoted pc ) are folded up , as is shown in fig9 . the protective cloth extensions are subsequently folded out to be used for attaching the fire barrier to the structure parts of the expansion joint . shown in fig9 is the 4 - way base folded up and out ready for the addition of the attachment parts . note that in the case of the 4 - way fire barrier there are two attachment parts . fig1 illustrates one attachment part . only one attachment part is shown in fig1 as the two attachment parts required in the construction of a 4 - way fire barrier are identical to each other and to the attachment part used in the t - shaped fire barrier . as in the t - shaped fire barrier , the “ flap support ” parts of the attachment parts ( part 2 in the t - shaped fire barrier ) are each inserted beneath one of the two 4 - way flaps . in this way , as in the previous example , insulator parts 20 then are in position to form the side barriers of the 4 - way flap extensions . once the two attachments are in position , as just described , the 4 - way fire barrier is ready for installation in a 4 - way extension joint . fig1 shows a plan view of a template used to cut and sew protective cloth to construct a vertical / horizontal 90 degree fire barrier to fit a vertical / horizontal 90 degree junction expansion joint without having excess cloth bulk or causing tearing of the cloth . the template teaches four cut lines . once these cuts are made in the protective cloth shaped according to the template , the cloth is folded about the four fold - out lines and two fold - in lines . the cloth is also to be folded about the two pair of angled pattern lines and then seamed , such as by being sewn together , for example , using the pattern lines as a stitching guide . the cutting , folding , and sewing of the protective cloth , as just described , results in the cloth assuming a chair - like shape , where the chair has arm - like and wing - like extensions . these extensions will be used to attach the finalized fire barrier to the structures . as in the previous examples , if stitching is the connection means used , high temperature thread is employed . fig1 is a plan view looking down onto a protective cloth patterned for cutting , folding , and seaming according to the vertical / horizontal 90 degree fire barrier template as illustrated in fig1 . in the designated ( see fig1 ) mid - area an insulation blanket has been positioned . positioned on the edge surface area of the insulation blanket is a layer of intumescent stripping material . as in the previous examples , the three layers are connected together by stitching with high temperature thread . fig1 , a perspective view , shows the cut , folded , and sewn vertical / horizontal 90 degree fire barrier ready for installation in a vertical / horizontal 90 degree expansion joint . fig1 a shows the barrier seamed by the use of pins and bolts “ installed ” in a model vertical / horizontal 90 degree expansion joint . in this figure , the barrier is attached to the model expansion by clamps . in will be appreciated , that in an actual structure the barrier is permanently installed using any functional attachment means , such as rivets . fig1 is a plan view of a template used in the folding and seaming of protective cloth used in the construction of a horizontal 45 degree fire barrier so as to produce a cloth to fit around an expansion joint that comprises a horizontal 45 junction without having excess cloth bulk or causing tearing of the cloth . cutting is not required to achieve the horizontal 45 degree fire barrier . in this example , the protective cloth , once cut to conform to the template , as shown , is folded and seamed along the fold and stitch lines and then folded up along the inner set of the fold lines and folded out along the outer set of fold lines . at this point , the protective blanket is ready for the addition of a layer of insulation blanket and a layer of intumescent material . fig1 is a plan view looking down onto a horizontal 45 degree fire barrier with attached layers of insulation blanket and intumescent material ready for installation in a the horizontal 45 degree expansion joint . fig1 is a perspective view of one end of the horizontal 45 degree fire barrier , as shown in fig1 , ready to be installed . fig1 is a plan view of a template used in the cutting , folding , and sewing of the protective cloth used in the construction of a horizontal t - joint / vertical fire barrier so as to produce a cloth to fit around a horizontal t - joint / vertical expansion joint without having excess cloth bulk or causing tearing of the cloth . the lines that are to be used as cutting guides , are illustrated in fig1 , as the lines marked with circles , whereas the lines that to be used as the pattern for folding and seaming are the lines marked with “ x ” s . the plain lines are guides for folding only . as seen in the figure , the t - shaped area on which a suitable shaped insulation blanket is to be placed is marked according . once the cloth has been cut , folded , and seamed according to the template as illustrated in fig1 , fig1 is a plan view looking down onto an unfolded , but t - shaped insulation blanket with an intumescent material layer positioned on the insulation blanket layer . these two layers are ready for fitting into a protective cloth cut and sewn following the horizontal t - joint / vertical fire barrier template as illustrated in fig1 . fig1 a , a perspective view of the cut , folded , and seamed fire barrier sized and shaped to fit a horizontal t - joint / vertical expansion joint with the insulation blanket and intumescent material , as shown in fig1 positioned in the cut , folded , and seamed fire barrier , shows the partially assembled barrier ready for the protective cloth , cut according to the template illustrated in fig1 b , to be positioned under and about the t - shaped extensions . fig1 b is a plan view of the template that is used to cut the two pieces of protective cloth , where each piece is to be positioned under and about the extended t - shaped extension arms , as illustrated in fig1 a . this addition provides a protective and supportive layer to hold the insulation blanket / intumescent material layers that are to be installed next . fig1 is a perspective view of the four additional insulation blanket / intumescent material parts that will complete the layered side walls for the t - shaped extension arm part of the horizontal t - joint / vertical expansion joint fire barrier . the insulation blanket / intumescent material parts , as shown in fig1 , are to be inserted inside of the protective cloth coverings ( i . e ., shown as a template in fig1 b ). the t - shaped structure ( as is shown in fig1 .) is shown again in this figure only as a guide for the placement of the insulation blanket / intumescent material parts . this step will complete the assembly of the horizontal t - joint / vertical expansion joint fire . fig1 a is a perspective view of a horizontal t - joint / vertical expansion joint fire barrier installed in a model horizontal t - joint / vertical expansion joint structure for seaming and for purposes of illustration . in this illustration the intumescent strip layer is about to be positioned on the insulation blanket side walls . the barrier is shown temporarily attached to the model structure with clamps . fig1 b is another view of the horizontal t - joint / vertical expansion joint fire barrier as shown in fig1 a . fig2 is a plan view illustrating four schematic multi - dimensional expansion joint structures . of course , it is appreciated that there are many variation of multi - dimensional expansion joint structures . fig2 is a perspective view of the novel work form that has been designed to hold the barrier that is shaped and sized to fit into a 90 degree expansion joint structure for seaming . fig2 a is another perspective view of the novel work form that is required for the seaming of a fire barrier that is shaped and sized to fit into a 90 degree expansion joint structure . thus , it can be seen from the above that the present invention provides the solution to the long felt and extremely important safety need for means to prevent the rapid spread of flames , heat , and smoke throughout multi - dimensional expansion joints of any type of structure by providing fire barriers styled and sized to fit multi - dimensional expansion joints , as well as the method of making the barriers , and the forms on which the barriers are seamed . moreover , as the multi -
