the horizontal meat slicer 10 of the present invention is shown best in fig1 - 5 as including a frame 12 on top of which is mounted a generally horizontal lower conveyor belt 14 . as shown in fig1 and 2 , belt 14 would preferably have a length of approximate seven to nine ( 7 to 9 ) feet , a width of approximately 12 to 18 inches and be constructed of a flexible rubber compound which is simple to clean and is durable in construction . movably mounted above lower conveyor belt 14 and extending generally parallel therewith is an upper pressing conveyor belt 16 which extends parallel with and is adjustably spaced from lower conveyor belt 14 . the upper pressing conveyor belt 16 is preferably mounted underneath a housing 18 which prevents accidental touching of the upper conveyor belt 16 , thus preventing injury . upper conveyor belt 16 and lower conveyor belt 14 cooperate to “ sandwich ” meat product placed therebetween and secure the meat product from movement during the slicing process other than the forward movement dictated by the rotation of lower and upper conveyor belts 14 and 16 . it should thus be noted that lower and upper conveyor belts 14 and 16 move at the same speed with the lower conveyor belt 14 rotating in a counterclockwise direction from the vantage point of fig1 while upper conveyor belt 16 rotates in a clockwise direction from the same vantage point . the height of upper conveyor belt 16 may be adjusted in various ways , however , a preferred adjustment method is shown in fig2 as including an upper conveyor belt mounting structure 20 which includes arms 22 a , 22 b , 22 c , and 22 d . the arms 22 a - d are pivotably mounted on the frame 12 and furthermore are operatively connected to a rotatable threaded rod 24 which extends and retracts thus pivoting arms 22 a - d and raising and lowering upper conveyor belt 16 and housing 18 accordingly . it is also contemplated and preferred that the upper conveyor belt 16 be mounted with tensioning devices operatively connected between the upper conveyor belt 16 and the frame 12 that act to draw the upper and lower conveyor belts 14 and 16 towards one another thereby pressing the meat product therebetween and securing it from twisting or rotation thereof . the cutting device of the present invention is a rotating blade which may be of several different types . the rotating blade is used to ensure quick and accurate cutting of the meat product as the meat product is moved through the horizontal meat slicer 10 . fig2 - 5 best disclose a first embodiment of the cutting blades of the present invention , which bears a passing resemblance to a bandsaw type of cutting device . the band saw blade cutting assembly 26 is shown best in fig2 as including a first blade support wheel 34 also known as a drive wheel , a second blade support wheel 36 , a drive motor 37 connected to the first blade support wheel 34 and a tension adjustment mechanism 42 . extending around the first blade support wheel 34 and second blade support wheel 36 are one or more bandsaw blades 38 a and 38 b , shown best in fig2 and 3 . each bandsaw blade 38 a and 38 b is mounted on the wheels 34 and 36 on one or more blade steps 40 a and 40 b . it should be noted that the present invention may be used with a single band saw blade 38 a or with multiple band saw blades 38 a and 38 b depending on the intended cuts to be made to the meat product , all of which fall within the intended broad scope of this disclosure . also , for clarity purposes the blade steps 40 a and 40 b are shown only on first blade support wheel 34 , specifically in fig6 but is to be understood by reference to fig2 that both the first blade support and second blade support wheels 34 and 36 may each include blade steps similar to that described in connection with first blade support wheel 34 . in the preferred embodiment , the blade steps 40 a and 40 b would consist of concentric disks having progressively smaller diameters , each of the blade steps 40 a and 40 b supporting one of the saw blades 38 a and 38 b . the band saw blades 38 a and 38 b extend around the outer circumference of each of the wheels 34 and 36 and the lowermost sections of the band saw blades 38 a and 38 b extend generally horizontally between first blade support wheel 34 and second blade support wheel 36 between lower and upper conveyor belts 14 and 16 . when the drive motor 37 is engaged , it drives first blade support wheel 34 to rotate , and the band saw blades 38 a and 38 b rotate with the first blade support wheel 34 and the second blade support wheel 36 , and thus are ready and positioned to cut meat product being propelled through the horizontal meat slicer 10 via lower and upper conveyor belts 14 and 16 . a blade tension adjustment device 30 is shown best in fig4 as providing an adjustment mechanism for the tensioning of band saw blades 38 a and 38 b . it has been found that such tensioning may be necessary in connection with the blades encountering the meat product due to the stresses placed on the band saw blades 38 a and 38 b during the cutting process . the tension adjustment device 30 used in the present invention would preferably operate by shifting the position of the related band saw blade 38 a and 38 b relative to its normal travel position , thereby increasing the tension on the saw blade . during the cutting of various types of meat product , such tension adjustment devices are quite necessary to insure proper cutting of the meat product . finally , it has been found to be advantageous to provide blade guides 46 , shown best in fig5 which are positioned on opposite sides of the conveyor belts 14 and 16 adjacent the travel location of the band saw blades 38 a and 38 b for guiding the band saw blades 38 a and 38 b and properly positioning the band saw blades to insure accurate cutting of meat product being fed through the horizontal meat slicer 10 of the present invention . in the preferred embodiment , the blade guide would be constructed of a teflon coated material which would be long lasting and durable . an alternative embodiment of the rotating blade of the present invention is shown in fig6 - 8 as including a butterfly blade assembly 50 which includes a generally circular meat slicing butterfly blade 52 which is mounted on a drive motor 54 mounted on the frame 12 . the only differences between the alternative embodiment of fig6 - 8 and the embodiment described and shown in connection with fig1 - 5 are those connected with the substitution of the butterfly blade assembly 50 for the band saw blade cutting assembly 26 . the arrangement and design of the conveyor belts , conveyor mounts and drive mechanisms therefor are substantially identical . in this embodiment , the butterfly blade 52 of butterfly blade assembly 50 would preferably consist of a generally circular planar saw blade having saw teeth formed on the outer circumference thereof , the saw blade being concentrically mounted on the drive shaft 56 of drive motor 54 as shown best in fig8 . the blade 52 extends generally horizontally from the drive shaft 56 and is positioned such that the blade is interposed between the upper pressing and lower conveyor belts 16 and 14 and extends over a section of lower conveyor belt 14 , as shown best in fig7 . when drive motor 54 is engaged , the drive shaft 56 is rotated at a high rate of speed and butterfly blade 52 rotates therewith such that meat product encountering butterfly blade 52 is sliced in a plane defined by the blade 52 . the butterfly slicing blade 52 extends outwards into the travel area of the meat product 100 such that as the meat product 100 travels through the slicer via the lower and upper conveyor belts 14 and 16 , it encounters the blade 52 . due to the offset of the blade 52 from the meat product 100 , the meat product 100 is only partially severed along the plane of the blade such that one section of the meat product 100 remains intact . the meat product 100 is then removed from the horizontal meat slicer 10 ′ and has been “ butterflied ” for further processing . the horizontal meat slicer 10 of the present invention is operated in the following manner . a meat product such as a pork butt or the like would be placed on the lower conveyor belt 14 and lower conveyor belt 14 would be engaged by a standard belt drive device ( not shown ) to commence to feed the meat product towards the blade assembly 26 . the control box 90 includes the on / off switch and other controls for the present invention , each of which would be understood by one skilled in the art . the meat product would then be engaged by upper conveyor belt 16 and lower and upper conveyor belts 14 and 16 would cooperate to compress the meat product between the belts thus preventing unintentional rotation of the meat product during the cutting process . the conveyor belts 14 and 16 would move the meat product into engagement with the band saw blade or blades 38 a and 38 b or the butterfly blade 52 which are rotating at a high rate of speed to ensure accurate , clean cutting of the meat product . as the conveyor belts 14 and 16 move the meat product forward , the meat product is cut in the planes defined by the horizontal locations of the band saw blades 38 a and 38 b or the butterfly blade 52 and due to the compression provided by the lower and upper conveyor belts 14 and 16 , the meat product does not separate , thus ensuring continued accurate cutting along the planes defined by the band saw blades 38 a and 38 b or the butterfly blade 52 . as the meat product moves entirely through the horizontal meat slicer 10 it has been cut horizontally along the locations of the band saw blades 38 a and 38 b or the butterfly blade 52 and as the end of upper conveyor belt 16 is reached , the meat product is moved into the removal area of the end of lower conveyor belt 14 for further processing . regarding such further processing , various types of finishing devices could be included with the present invention , such as an interleaver 80 , dicer assembly 82 or a slitter 84 , the operation of which would be understood by those skilled in the art of meat processing . it is to be understood that numerous modifications and substitutions may be made to the present invention which fall within the intended broad description of the invention . for example , the precise design layout of the horizontal meat slicer 10 of the present invention may be modified so long as the intended functioning of the invention is not disrupted . furthermore , the blade assembly 26 may be modified or changed as needed to permit the cutting of various sized and shaped meat products . finally , although it is preferred that the structural elements of the present invention be constructed generally of stainless steel and the conveyor belts of a rubber compound , it should be noted that various types of materials for construction may be used so long as the functionality of the present invention is not diminished . there has therefore been shown and described a horizontal meat slicer which accomplishes at least all of its intended objectives .
a horizontal meat slicer includes a frame and a lower conveyor belt having forward and rearward ends , the lower conveyor belt operative to receive a meat product thereon and transport it into and through the device . an upper pressing conveyor belt includes forward and rearward ends , the upper pressing conveyor belt and the lower conveyor belt cooperating such that meat product is compressed between the lower conveyor belt and the upper pressing conveyor belt . a rotating blade is mounted on the frame , the rotating blade having a cutting edge interposed between the lower conveyor belt and the upper pressing conveyor belt . finally , at least one drive device such as a motor is operatively connected to each of the conveyor belts and the rotating blade to drive them to pull the meat product through the device and cut the meat product via the cutting edge of the blade .
