referring to fig1 an isometric view is shown of the sewn thimble 10 of the subject invention . fig2 and 3 , in turn , respectively show the thimble 10 of fig1 when folded open along its right and left lateral seams and a longitudinal cross sectional view through the thimble . referring to fig1 it is to be appreciated the thimble 10 is of an elongated construction approximately 3 - 5 inches long , and mounts over the first two phalanges of a finger in conforming relation to the finger tip . mounted interiorly of the thimble in the lower surface of the shell or envelope 12 in the region of the finger tip is an impenetrable or rigid member 14 ( reference fig2 and 3 ) which protects the fingertip while sewing . although the thimble 10 is shown when worn for heavy duty needle work with the multi - walled surface 16 facing down , alternatively , the thimble may be rotated to position the upper , single - walled surface 18 of the thimble 10 in covering relation to the fingertip . in the latter position , fine needle work may be effectuated . that is , the softsided , pliable nature of the thimble envelope 12 provides a greater flexibility and finger tip dexterity . in its typical construction , the outer envelope 12 is constructed of a soft leather , although a variety of other supple , yet heavy duty materials might be employed . for that matter , the outer cover on the upper surface 18 might be of a dissimilar material to that on the lower surface 16 . for example , the fine work surface 18 might be a leather and the heavy duty surface might provide for a closely woven nylon or canvas material to cover the impenetrable member 14 or vice - versa . moreover , while the embodiment shown contemplates different surfaces 16 and 18 constructions , they may be of the same construction . thus , two impenetrable members 14 might be used or none at all . in any case , the mounting of the thimble 10 is facilitated by way of a finger grab or pull - tongue 20 which extends from the extreme end of the fine sewing surface 18 . during mounting , the wearer grasps the tongue 20 and pulls the thimble 10 tight onto the fingertip . this action firmly sets the thimble 10 about the fingertip and an interiorly included elastic strap member 22 which is sewn diametrically across the interior bore and which extends forward to a point slightly behind the member 14 . although a single pull - tongue 20 is provided , a pair of such tongues might be included on each surface such that one is always accessible on the upper finger surface which is the preferred position when mounting the thimble 10 . with attention directed to fig2 and 3 , the tip mounted impenetrable member 14 and elastic strap 22 can better be seen in their normal mounting orientation . the impenetrable member 14 is particularly cut out of a piece of flexible izing glass , plastic , metal , or other similar impenetrable material of an approximate thickness in the range of 1 / 64 to 1 / 16 inches . it exhibits an elongated , ovular shape and is positioned adjacent the fold line 24 of the pre - cut envelope material . an interior fabric cover 26 is sewn over the impenetrable member 14 to secure it to the inner wall and provide a liner adjacent the fingertip . the strap of elastic 22 is sewn across the outer end of the surface 16 supporting the impenetrable member 14 and provides an interior adjustment loop when the fine surface portion 18 of the thimble 10 is folded over and sewn to the heavy duty surface 16 . as seen in fig3 the elastic strap 16 generally bisects the interior cavity such that the strap may mount above or below the wearer &# 39 ; s finger . preferably though the strap mounts beneath the finger . the strap also extends to the edge of the opening to the thimble 10 to facilitate mounting and also to prevent the thimble from pulling off the finger during use . additional straps may be included if necessary to prevent removal . one other variation applicant has considered is the venting the envelope walls to minimize perspiration over protracted periods of usage . as mentioned , this may be accomplished by using an open weave material as part of the shell 12 . in contrast , the prior art has typically provided random vent holes in a solid walled envelope . while the present invention has been described with respect to its presently preferred embodiment and various modifications thereto , it is to be appreciated still other embodiments might suggest themselves to those skilled in the art . it is accordingly contemplated the following claims should be interpreted all those equivalent embodiments within the scope thereof .
a two - sided thimble including an elastic fitting member and a hand pull flap . a first envelope surface permits fine needle work and a second surface including a contained rigid protective member facilitates heavy duty needle work . in an alternative construction , each surface may accommodate either heavy or fine needlework .
