I 1 . . ' Referring now in detail to the drawings, 10 designates a table or support on which is mounted a slicing machine l2, embodying the invention, ?xed to said support by a clamp l3. The ma chine I 2 comprises a base l5'having a top sur face I 6‘ and being provided with a raised por tion I‘! having a top wall l8, side walls l9 and 20 and end walls 2|. The side wall l9 de?nes 10 one side of the base and the surface or wall l6 extends to one side of the other side wall 20. The end walls 2| are located inwardly of the outer ends of the base, providing ledges 2Ia at the opposite ends of the base, disposed flush with 15 the wall I6. - and arrangement of parts which will be exem Fixed to the wall I6 is a housing 22 substan pli?ed in the construction hereinafter described, tially closed on one side by wall 23 and open on and of which the scope of application will be 20 indicated in the following claims. In the accompanying drawings, in which is shown one of the various possible embodiments of this invention, _ Fig. 1 is a side elevational view of a slicing ma 25 chine embodying our invention; Fig. 2 is a top plan view of our improved ma chine; . Fig. 3 is an end view of my improved machine with parts broken away to show the interior construction; > Fig. 4 is a cross-sectional view taken on line 4-4 of Fig. 3; Fig. 5 is a cross-sectional view taken on line 5—5 of Fig. 3; Fig. 6 is a fragmentary, enlarged, detail view of the grinding device in one position thereof; Fig. '7 is a cross-sectional view taken on line 1--'i of Fig. 6; Fig. 8 is a perspective view of our improved support. Fig. 9 is a side elevational View of a grinding device embodying the invention and illustrating a modi?ed construction applied to the slicing ma chine; Fig. 10 is a cross-sectional view taken on line lll—l? of Fig. 9; the opposite side, and having an end wall 24 at one end and a top wall 25 at the top forming 20 said end wall. Rotatably mounted on said wall 23 is a shaft 26 to which there is ?xed a pinion 21 and a circular cutter blade or knife 28. The blade 28 has an inclined edge surface 28a on one‘ side and a ?at surface 28b on the opposite side 25 thereof. The wall 23 is formed with an outwardly extending boss 30 forming a bearing for a shaft 3|, to the outer end of which there is ?xed 'a crank handle 32. Fixed to the inner end of the shaft 3| is a pinion 33 meshing with the pinion 21. 30 It will now be understood that upon rotating the crank handle 32, the blade 28 will rotate. As shown in Fig. 1, the wall 23 is cut away as at 29, to expose a portion of the cutting edge or periphery of the blade 28. 35 Means is provided for reciprocating the object or food to be sliced past the blade 28. To this end, there extends upwardly from the four cor 40 clamp for attaching the “machine to a table or 45 trating a modi?ed form of actuating means for the ' Fig. 11 is a view of the structure shown in Fig. 9 from an opposite side; Fig. 12 is a view similar to Fig. 10, but showing the grinding device in inoperative position; and Fig. 13 is a cross-sectional view taken on line l3-l3 of Fig. 12. Fig. 14 is a fragmental elevational view illus 55 ners of the top wall [8, lugs 36 supporting a pair of parallel rods or rails 31 ?xed at the ends there 40 of to the tops of said lugs, and being spaced above . said wall. Slidably mounted on the rods 31 is a carriage 40 comprising a bottom corrugated wall 4| and an upstanding wall 42 at oneend of said corrugated wall. Fixed to the underside 45 of said corrugated wall 4| are pairs of sym metrically disposed, angle-shaped members-A4, each having a horizontal wall 44a ?xed to the underside of said corrugated wall, and a down wardly extending wall 45 formed, with an open; 50 ing 46 receiving therethrough one of the rods 31. An angle-shaped plate 42d ?xed to the wall 42 and having a wall 42b extending away there from, serves as a handle for manipulating the carriage. 5.5 2 2,119,760 It will now be understood that the carriage 40 may be reciprocated parallel to the circular cutter 28, whereby the food to be sliced mounted on the carriage, may be brought past the cutter for the slicing operation. Mounted on said car riage is a member 50 for gripping the food on the sliding carriage, to hold it rigid during the slicing operation. The member 50 may be made of sheet metal and comprises a vertical wall 5| parallel I00, preferably having cut out portions IM to re duce the weight thereof. Extending from the lower end of the wall I00 is a lug I02 provided with a screw threaded opening I03. Extending from the upper end of the wall I00 on one side thereof is a short arm I04 having a downwardly extending ?at edge I05 parallel to the wall I00. Extending from the other end of the wall I00 is a longer arm I06 having a downwardly projecting 10 to the rods 31 and being formed with spurs-52; circular pin portion I01. preferably cut from the metal thereof and pro jecting toward the rotary blade. Extending from the wall 5| at right angles thereto is a vertical wall 53 contacting the wall 42 and having at the upper end thereof a folded over edge, 55, form ing a groove slidably receiving ‘the upper edge 56 of said wall 42. It will now be understood that the member 50 may be moved in a direction transverse to the direction of movement of the carriage, whereby to press the food toward the cutting blade. ~ Means is provided for adjusting the thickness of the slices. To this end, the wall I6 is formed adjacent one end thereof with an arcuate slot 60. The end wall 20 is formed (as shown in Fig. 5) with a boss SI, to which there is screwed a vertical screw 62 having a smooth shank por tion 63, and a head 64 at the lower end thereof. Rotatably mounted on the shank portion 63 of the screw 62 and supported by the head 64 is a lever 65 having an arm 66 extending below the wall 16, provided with a handle 61 extending through the slot 60. The lever 65 is further pro vided with an arm 68, at the other end of which there is a cammed ?ange 69. The walls I 9 and 20 of the base are formed with bearing openings I9a and 20a, slidably re ceiving therethrough a shaft ‘I0. Fixed to one end ‘II of said shaft is a gauge or guide plate 12 disposed substantially parallel to the rotary blade 28 and having 'an arcuate edge ‘I3 substantially conforming to the exposed edge of said blade. Fixed to the plate ‘I2 is a guide pin ‘I5 extending through an opening ‘I6 in wall 20. Mounted on the rod ‘I0 is a plate 80 having an opening 8| receiving said rod therethrough and being ?xed thereto by a set screw 82. The plate 80 is provided at the bottom thereof with a hori zontal lug 83 contacting the underside of the cam 60. There is further mounted on the rod ‘I0 a block 85 likewisehaving an opening 86 receiv ing the rod therethrough and being ?xed thereto by a set screw 81. The block 85 is formed with a recess 90 receiving a spring pressed rounded plunger 92 contacting the inner surface 69a. of the cammed ?ange 69. The outer surface 69b of said cammed ?ange contacts the member 80. It will now be understood that the cammed flange is received between the members 80 and 85. GI) Upon turning the handle 61, the lever 65 will rotate about its axis 62 and will cause sliding movement of the rod '10 by'reason of the engage ment of the cam 69 between the members 80 and 85, which are ?xed to said rod. 7 The edge 60a of the wall I6 adjacent the arcu ate slot 60 may be provided with a scale 93 to indicate the position of the gauge plate ‘I2, and hence to indicate the thickness of the slices. The scale may he graduated to indicate the number 7 70 of slices per inch. It will now be noted that a very ?ne adjust ment may be obtained, since a swing of the lever 65through a substantial angle will move the rod ‘I0 a comparatively short distance. 75 H . The clamp I3 is provided with a vertical wall The wall I6 of the base of the machine is provided adjacent one end thereof with a circular opening IIO rotatably re ceiving the pin portion I0'I. The adjacent ledge 2 la. is formed with a depression I I I for receiving the edge I05 of the arm I04 of the clamp. 15 Received within the screw threaded opening I03 of the lug, I02 is a screw II3 having a ?nger piece I I4 at the bottom end thereof, and a plate H5 at the upper end thereof, adapted to contact the underside of the table or support I0. It will now be understood that upon screwing the screw H3 against the underside of the table, the arms I04 and I06 will be pressed against the ledge 2Ia and wall I6 of the base, and the edge I05 and pin I07 will be retained within the depression II I and opening I I0 for clamping the machine ?rmly to the support I0. The clamp may be released by merely unscrewing the screw II3 sufficiently to release the edge I05 from the recess III. It will be noted that when the clamp is ?xed in 3O position, the machine cannot rotate with respect to the clamp. Means is provided for sharpening the rotary blade 28. Extending from the wall 23 of the blade housing 22 and adjacent the top wall 25, 35 is a lug I20 having an opening I2I disposed in a vertical plane, and an adjacent inclined opening I22. The sharpening device I23 comprises a curved member I25 having a handle portion I26 at one end and being provided with a pin I2'I at 40 the opposite end. At an intermediate portion thereof the member I25 is formed with a bear ing I28 receiving therethrough a shaft I29. Mounted on one end' of the shaft is a grinding wheel I30, and ?xed to the other end of the shaft is a nut I3I. ' - It will be noted that when the pin I2'I is re ceived within the opening I2 I, the grinding wheel £30 will be disposed in a vertical plane and may be moved by manipulating the handle portion I26 against the ?at surface 28b of the blade 28. However, the member I25 may be lifted to re move the pin I2'I from the opening I2I and said pin may then be inserted within the inclined opening I 22 to bring the wheel I 30 into an in 55 clined plane, as shown in Figs. 6 and 7 of the drawings. By manipulating the handle I28, the wheel I30 may then be brought against the in clined surface 28a of the blade. With the grind— ing wheel against the surface 280, or 281), rota 60 tion of the blade will cause a quick sharpening of the blade. When the grinder is not in use, the same may be entirely removed from the machine. In Figs. 9 to 13, inclusive, there is shown a modi?ed form of grinding implement. As shown‘ 65 in said ?gures, the housing 22a for the rotary blade 28 is provided adjacent the top thereof with a cut away portion I40. The top wall 25a and the side wall 23a of said housing are cut away to expose a portion of the blade 28 at the 70 top. The wall 23a of the housing is formed with a lug I4I below the edge I40a formed by the cut away portion I40. Said lug MI is formed with a vertical through opening I42. The grinding de vice I23a shown in Figs. 9 to 13, inclusive, may 75 3 2,119,760 be mounted on the lug Ill! in operative and in operative positions, as willbe more clearly here inafter explained. Said device I23a comprises a vertical pin Hill, the bottom end of which is re ceiv-cd withi‘ the opening 542 of the lug I4I. Fixed to an intermediate portion of the pin I44 is a Z-shaped guard I45. The guard comp-rises a bottom wall Iii‘; formed with an opening I41 1 receiving the pin hi4 therethrough and being 10 ?xed to said pin by a screw Hi8. Extending up wardly from the wall M5 is an inclined wall I50, and extending from said inclined wall is an out wardly extending wall I5I. Said wall I5I sub— stantially corresponds to the portion of the top 15 wall 25a which has been cut away. Thus, in the position shown in Fig. 12, with the grinding de vice in inoperative position, the guard substan tially covers the cut away portion I40, and hence completes the housing 22a for covering the top 20 portion of the rotary blade 28. Fixed to the upper end of'the pin I44 is a‘ housing I 55, preferably made of two parts I500. and I682), screwed together by a screw IN. The housing portion I'GBb may be formed with an internal boss I62, on which is rotatablymounted a circular vertical grinding wheel I63. Fixed to the inside of the housing part I?ila is a boss “52a, on which is rotatably mounted an inclined cir cular grinding wheel "53a. The bottom of the 30 housing part ISIla is cut away as at IN, to re ceive the top of the blade 28 when the grinding device is in operative position. In the position shown in Fig. 12, the guard I45 covers the cut away portion I 40 of the blade housing 22a and the housing I50 is turned away from the blade housing. In this position the grinding device is not in use. However, the grinding device may be moved to the position shown in Fig. 10 by lifting said device, turning all) the same 180 deg, and then reinserting the pin I44 within the opening I42. In this position the guard I45 is turned away from the blade and the grinding wheels I53 and "5311 contact oppo site surfaces of the portion of the blade. Rota tion of the blade will then cause the outer edge thereof to be ground and sharpened on both sur~ faces, which projects into housing I60 through opening I61. For turning the rotary blade, a flywheel I ‘H! as shown in Fig. 14 of the drawings may be sub stituted for the crank handle 32, said flywheel being mounted on the shaft SI and having a handle Ill adjacent the periphery. With this construction a greater uniformity of speed of the cutting blade 28 may be obtained. It will thus be seen that there is provided a device in which the several objects of this inven tion are achieved, and which is well adapted to meet the conditions of practical use. As various possible embodiments might be made of the above invention, and as’ various changes might be made in the embodiments set forth, it is to be understood that all matter here in set forth or shown in the accompanyingdraw ings is to be interpreted as illustrative and not in a limiting sense. . v ' Having thus described our invention, we claim as new and desire to secure by'Letters Patent:1.
