This invention relates to slicing machines, and particularly to an improved bacon slicing machine which may be readily adpisted to slice bacon on a bias or in the usual transverse manner.

Another object is to provide a slicing machine wherein bacon or other meat may be supported and fed either horizontally or upvardly on an incline to a cutting knife which functions the same regardless of the angle of the bacon.

A still further object of the invention is to provide a slicing machine which may be ad justed during the operation of the mach'me so as to cut at different angles according to the thickness of the bacon.

A still further object of the invention is to provide a bacon slicing machine wherein a specially constructed pivotal support is provided for one end of the bacon table so that the bacon may be swung at different angles without the end of the table moving away from a certain vertical line. i

Referring to the accompanying drawings by numerals, 1 indicates a. frame of any desired kind which is provided with anydesired number of bracing members 2 so as to hold the frame in proper place At or near Serial No. 290.944.

the top of the frame 1 is a shaft 3 supported in suitable journal boxes and carrying at one end a knife 4 used for cutting the meat, as hereinafter fully described. At the end of shaft 3 opposite knife 4 is arranged a sprocket wheel 5 carrying a chain 6 which may be of the silent type or any desired type. This chain passes over a sprocket wheel 7 connect ed to the shaft of the electric motor 8 which is supported on a. suitable bracket. or support 160 S) connected in any desired manner with the frame 1. A sprocket ,wheel 10 is connected with shaft 3 and accommodates the sprocket chain 11 which passes over a sprocket wheel 12. whereby whenever motor 8 is functioning knife 4 will be functioning and sprocket wheel 12 will be rotating. As shown in Fignectcd to the shaft 21. by a universal coupling 22. The shaft 21 is carried by suitable bracket 23, said bracket being rigidly secured to a bacon table 2 1, which table is swung upwardly and downwardly, as hereinafter fully described. A gear wheel 25 is rigidly secured to shaft 21 and is continually in mesh with the pinion 26 which is rigidly secured to the. screw 27 supporting suitable journal members carried by the bacon table 24. The screw 23 is adapted to be rotated by the pinion 26 but not to move longitudinally. The function of the screw 27 is to cause the traveling member 28 to move upwardly or toward the pivotal point of the table 24 to fccd'the bacon 29 toward the knife 4. After a piece of bacon has been fed to the knife 4: and has been out except for a small piece at the end. certain parts of the traveling member 28 are operated whereby this traveling member is released from operative engagement with the threads of the screw 27, thus permitting this member to be moved manuallyback to its. starting point or to substantially the position shown in Figures 1, 7 and 8. This is done manually and when done a new piece of meat is mounted on the table 24 ready to be forced toward knife 4. This operation may take place while the machine is functioning or while the machine is not operating. The traveling member 28 and associated parts are substantially the same as shown in my copending application Serial No. 221,311 although some slight changes have been made in certain details. As indicated more particularly in Figure 9, the traveling member 28 is provided with a sleeve 30 loosely fitting over the screw 27 said sleeve having a depending bracket 31 for receiving one end of spring 32, which spring is connected at the opposite end to the extension 33 of the lever 34 pivotally mounted on pin 35. Pin 35 is journaled in suitable ears 36 extending from the sleeve 30. Lever 34 is provided with a handle or grip 37, whereby it may be manually raised or lowered and when raised is held in an upper position by the spring 32. Lever 34 is provided with an elongated slot 38 which accommodates the pin 39 extending through the'block 40 which is threaded at the lower end with threads of a size to interlock or coact with the threads of screw 27. hen the parts are in the position shown in Figure 9, the threads of block 40 are engaging or meshing with the threads of screw 27 and if this screw is rotating the sleeve 30 and associated parts will be propelled. In order to hold the lever 34 so that the threads of block 40 will mesh with the threadsof screw 27, a hook 41 extends over the upper edge of lever 34. This hook is pivotally mounted by reason of pin 42 and extends through a comparatively large aperture 43 in the depending arm 44. The end 45 of hook 41 is positioned so as to strike the abutment 46 when the traveling member 28 has moved to its nearest point adjacent knife 4. As soon as the hook 41 has been swung so as to become disengaged from the lever 34 spring 32 will begin to function and will immediately raise block 40 out of engagement with the screw 27. If nothing is done with the traveling member 28 there will be no more feeding action, but if the machine is to be used further traveling member 28 is pulled downwardly to the position shown in Figure 1 or later to the position shown in Figure 8, as the case may be, and then a new piece of bacon mounted on the bacon support or table 24. Vhen this has been done the pointed ends 47 of the swinging members 48 are forced into the end of the bacon. The members 48 are pivotally mounted on the shaft 49 which is carried by the arm 44 and are preferably spaced by suitable sleeves 50. After the pointed members 47 have been properly set, lever 34 is swung downwardly and hook 41 is moved to snap thereover, whereupon the traveling member 28 will begin to function thereof. This screw is mounted on the bacon support or table 24 and the support could be used in a horizontal plane, as shown in Figure 8, at an angle as shown in Figure 1 or at any intermediate point, as preferred. The angle of the table 24 and the thickness of the bacon determine the widtlrof the slice. In packing sliced bacon it is desirableto have all the slices of the same width, and consequently means have been provided for quickly swinging the table 24 upwardly or downwardly at any time to take care of different thicknesses of bacon and still provide slices of the same width. As shown particularly in Figure 8, a bracket 51 is secured to the bottom of the bacon table 24 and to this bracket is pivotally secured the racks 52, said racks continually meshing with a pinion 53. A guide 54 guides the racks 52 and holds the same in mesh with pinion 53. Pinion 53 is rigidly secured to shaft 54 which is supported by suitable brackets 55 carried by the frame 1, said shaft at one end carrying a worm wheel 56 which continually meshes with the worm 57. The shaft 58 extending from worm 57 carries a hand wheel 58' which, when rotated, causes the worm wheel and associated parts to function for raising or lowering the racks 52 and the table 24. These parts may be caused to function while the other parts are functioning. In mountin the table 24 so as to swing as above outlined: a special pivotal support or mounting is provided which is shown particularly in Figures 1, 2, 4, 5 and 6. This structure is especially provided in order that the point 59 (Figure 5) will remain in the same place. As the knife 4 passes very near this point it is necessary to maintain this point in the same relative place as the table moves upwardly and downwardly, in order that the knife will not strike the table. In order to accomplish this result a disk 60 is provided and formed with a web 61 secured by bolts 62 or by other suitable means to the frame 1, as shown in Figure 2. It will be understood that there are two disks 60 arranged so as to face each other, as shown in F igure 2. and the description of one will apply to both. The disk 60 is provided also with an areshaped groove 63 designed to receive the areshaped web 64 of the plate 65. Plate 65 is provided with an outstanding web 66, bolted, welded or otherwise rigidly secured to the table 24. The end portion of the table 2.4 is

secured to the respective plates 65, so that as the table is moved upwardly and downwardly the point 59 will remain in the same place. Asshown in Figures 5 and 8, the parts are so proportioned as to permit the device to be used in a horizontal position, or in an inclined position. Regardless of the angle of the table'24, the point 59 of the table will remain in the same place, and consequently as the meat is forced past this point it is cut by knife 4 in the proper manner.

What I claim is 1. A bacon slicer, including a rotatable knife, a bacon table, means for pivotally mounting the table so that it niay be swung from a substantially horizontal position to a 45 angle, means including a traveling member for forcing the bacon along said ta.-

- ble toward said knife, and power means connected with said knife and with the means for forcing the bacon along the table, whereby the movement of the bacon will be in proportion to the speed of the knife.
