Specification of Letters Patent. 3 Patented June 22, 1920.

Application filed September 29, 1919. Serial No. 327,061.

This invention relates to that class of slicmg machines in which a knife or cutter blade has a reciprocating movement in actual use, an example of which forms the subject matter of my prior application for Letters Patent, Serial No. 2' 76,i73, filed February 12th 1917. And the present improvement has for its objects 1% a To provide a structural formation and association of parts whereina short and rapid vibration in a horizontal plane is imparted to theknife or cutter blade during the gradual downward movement of the same through the material. undergoing a slicing operation and thus attain a rapid V and very effective cutting action.

To provide a sin'iple and eifieient means for feeding the material to be sliced with the attainment of uniform regularity in the thickness of the slices produced and in which the feeding mechanismis adapted to be moved down and out of'the way, when it is desired to oleanthe machine parts, all as willhereinafter more fully appear.

In the accompanying drawings:

Figure 1, is 'a front elevation of a slicing machine embodying the preferred form of the present invention.

Fig. 2, is a plan view of the same.

Fig. 3, is a detail side elevation with parts in section, illustrating the step by step feed mechanism of the machine.

Fig. 4, is a detail longitudinal section illustrating the adjustable carriage of the serrated feed wheel of the machine.

Fig. 5, is a longitudinal section on line 5. 5. Fig. 1. j

Fig. 6, is an enlarged detail section of the cutter blade and its carrier.

Fig. 7, is a detail perspective view of the operating mechanism of the step by step feeding means above referred to.

Like reference numerals indicate like parts in the several views.

Referring to the drawings, 1 designates the material supporting bed plate or base of the machine, provided with the usual fined side abutmentqplate or 'wall 2.

3 designates a guide standard secured to one s de of the base 1 1n transversely removed relation to the aforesaid abutment wall2, and preferably of the detail construction set forth in my prior application Serial No. 276,473, and formed with a guide slot or trackway 4 in inclined relation to the horizontal plane of the base 1, with said guide slot comprising an upper and outer angular portion 5 having a greater inclination from a horizontal plane than the lower and'inner angular portion 6 of said guide slot, as shown in Fig. 1.

7 designates a transversely arranged cut ter carriage of an elongated bar form, pro vided at one end with a cross-head or stud 8 having sliding engagement with the guide slot or trackway 4L aforesaid. At its other end the carriage 7 is pivotally connected to the upper end of a radius link 9 which is formed with an elongated slot 10 having operative engagement with the driving mechanism of the machine, as follows: I 11 designates the primary power shaft of the machine, journaled longitudinally in bearings at the side of. the abutment plate or wall 2, and preferably receiving motion through a pair of bevel gears 12 from a transverse countershaft 13 capable of convenient manual rotation.

14: designates a secondary power shaft arranged in parallel relation to the primary shaft 11 and receiving slower speed therefrom through a gear wheel and pinion connection 15 as shown in Figs. 1 and 2.

16 designates a crank disk secured to the secondary shaft 14, and having a crank pin engaging the elongated slot 10 of the radius link 9, and adapted to impart a downward oblique movement to the cutter carriage 7 in actual use, and as set forth in detail in my prior application Serial No. 276,473.

17 designates the cutter blade or knife of the machine, of a straight blade form, and

having a guide flange 18 at its back for sliding engagement in a correspondingly formed guide channel in the carriage 7 aforesaid. In the present improvement the cutter blade 17 has a rapid and short stroke reciprocation in the carriage 7 With a view to attain rapid and effective cutting action and to such end has operative connections as follows:

19 designates a sliding head or standard moving in transverse guides 20 on the base 1 in adjacent relation to the aforesaid guide standard 3 and provided with a vertical guide channel for engagement with a pin or stud 21 on the side of the cutter blade 17 to form an operative connection be tween the parts which permits of an inde pendent vertical movement of the pin or stud 21 in said guide channel in the practical operation of the machine.

22 designates a lever pivoted to the base 1, with one end operatively connected to the sliding head 19 aforesaid, and with the other end connected by a connecting rod 23 with an operating cam mechanism as follows:

24: designates a cam disk fixed on the primary shaft 11 and form with an annular cam groove of a sinuous form, cngaginga roller 26 011 the end of the aforesaid connecting rod 23 to impart a number of reciprocations to said connecting rod 23, and to the associated sliding head 19 and cutter blade 17, with each revolution of the cam disk.

2'7 designates an adjustable gage board secured to the base 1 and adapted to maintain the article being sliced in proper position against the side abutment plate or wall 2.

28 designates one or more serrated feed wheels extending up through and a short distance above the top surface of the base 1, through suitable slots therein, and adapted for feeding engagement with the under surface of the material being sliced.

29 designates a carriage or frame hinged at one end to the under side of the base 1 and provided with ournal bearings for the carrying shaft 30 of the feed wheel 28 aforesaid.

31 designates a spring associated with the carriage 29 and adapted to yieldingly force the same upward and maintain the feed wheel 28 in proper operative position.

32 designates a cam or eccentric mounted on the underside of the base 1 and having engagement with the free end of the carriage 25), and a daptcd to move said carriage downwardly when it is desired to depress the feed wheel 28 below the top' surface of the base 1 previous to a cleaning operation on the machine parts. -And to such end the carrying shaft of the eccentric 32 is provided with an operating knob or handle 33 for convenient manual operation.

34 designates a ratchet wheel fixed on the carrying shaft 30 of the feed wheel 28, and 35 designates a rock arm associated with said shaft and carrying a spring dog or pawl 36 adapted for operative engagement with the ratchet wheel 34 aforesaid.

37 designates an inclined lug formation on the rock arm 35 and l cated in the path of a corresponding inclined lug formation 38 on the radius link 9 heretofore described and so that as said radius link 9 nears its vertical position the lug 38 will contact with the h1g3? to swing the rock arm in one .trackway, a cutter direction and cause the dog or pawl 36 to engage the ratchet wheel 34 and impart a partial rotation to the same and to the feed wheel 28. Such operation takes place as the radius link 9 nears its vertical position and with the cutter blade 17 in a correspondingly elevated condition to permit a free passage of the material thereunder.
