Application filed January 12, 1922. Serial No. 528,803.

T (ZZZ/whom it may concern Be it known that l, biononor; 'Wimz, a citizen oi? the United States, and re ident of 5, Flg. 4.;

Rochester, in the county oi Monroe and 5 State of Yew Yorlnhave invented certain new and useful Improvements in Slicing Machines, of which the following is a specification.

The. present invention relates to' slicing machines and an object thereoi is to provide an improved means tor feeding toward the cutter a table or carriage on which the material to be sliced lSllBlCl. Another object of the invention is to provide means for pro-- venting any hack lush in the carriage which su p mrts the materialtohe sliced so that the pressure of the cutter upon the material on the carriage will not shift the carriage and produce uneven slices. A further object of the invention isto provide in connection with a mechanism for feeding the carriage toward the cutter step by step, a friction clutch which will hold the carriage in its shifted position so that it will not. he moved backwardlyby pressure'on the material during the cuttingaction. Still another ohiect of the inventionis to provide a-means-bv which the carriage on which the mat rial to be sliced is arranged may betreed in the feeding or shitting mechanism and also from a back lash clutch to permit such carriiug e to be shifted away lrointlie cutter. A still further object of the invention is to provide an improved mechanism for feeding the carriage in the direction of the plane of operation of the rotary cutter and driven. with said mechanism. further object ot' the invention is to provide an improved means for securing the guardfor the rotary cutter in operative position.

To these and other ends, the invention consists of certain parts and combinations of parts, all of which will be hereinatter described, the novel features being pointed out in the appended claims.

In the illustrated embodiment of thej'invention, ther'eha's been provided a base 1 from which rise two uprights 2 and 3 con nected by an intermediate cross member 4. Connecting the uprights 2 and 3 above the cross piece 4 is a shaft 5 on which a dish or circular cutter 6 is secured as by nalled in the cross piece 4., said shaft 10; also having a crown gear 11 secured tlieretoQand meshing with a bevelled gear 12 on an ppin joi irnalled on the cross piece -lendfin the upright piece 2 and having a crank handle 14 thereon through which movement of the rotary cutter 6 is effected. Operable on the frame and particularly, in this instance, on the side frames 2 and 3 in the line a, nut 7. i This shaft is provided with a bevelled pmion 8 which meshes with a crown gear 9,

a direction substantially parallel with the plane of operation of the disk or rotary cut ter 6 is a carriage '15. In order to guide this carriage, the guiding surfaces 16 and 17 are provided, respectively, I on the side trams pieces 2 and 3. The guide surface 16 is overhung by a projection 18'wliich"cooperates with the upper surface otthecarriage, while the guiding surface}? is overhung by a projecting rib 19 which entends into a groove or recess 20 formed n the side ot a depending projection 21 on the,

under sideof the carriage I The opposite side of this depending projection :2lis engaged by a removable retaining strip'22 securedto the side piece 3 byscrews 23. I

Movement, of thejcarriage 15 may beef- ,fected in any suitable manner but it is preterred to operate the same so that each retation of the crank shaft 13 will effect a complete back and forth movement oi? the carriage 15. This result, in' this instance, obtained by providing a lever 24 pivoted at to the upright 2 and at 25 to one end of a link 27 which in turn is pivoted at 28 to the under sideol the carriage 15. The link 24 has pivoted thereto at 29 a link or pit man 30 which in turn is pivoted at 31 at an eccentric pointon the crown gear 9, so that motion is transmitted. from said crown gear, in the rotation of the latter, to the le and from the latter by way of inn. the carriage 15.

The carriage 15 also acts as a support for a carriage in this instance, in the form of a plate or table guided by guide strips and 34 on the carriage 15 at a right angle to the line of n'iovement of said carriage 15, so that the carriage 32 moves on the carriage 15 on a line substantially at a right angle to the plane ot' operation of the rotary cutter 6. v

The movement of the carriage 32 may be effected in any suitable manner. In this instance, the carriage 32 has on its under side a tooth or rack bar 35 with which a pawl 36 is adapted to engage through a tooth 37, this pawl 36 being pivoted at 38 to one arm of a swinging or bell crank member 39 which in turn is pivoted at 40 to the carriage 15. A spring 41 acts between the swinging member 39 and the pawl 36 to maintain the tooth 37 toward the tooth bar 35. Tothe swinging mem her or hell crank lever 39, a link 42'is pivotedat 43, this link also being pivoted at 44 to an adjustable lever 45 which is pivoted at 46 to the carriage 15. A. spring 4'? connects the link 42 with the swinging member 39 and tends to hold the adjustable lever 4.5,link 42 and swinging member 39 so that the pawl will lie in cooperation. with the tooth bar 35. The lever 45 has an extension or arm 48 at one side oi: the carriage 15 to cooperate with a side taco 2 the 'i'ranie piece 2 just prior to the carriage 15 reaching one end of its movement. When this projecting arm 48 cooperates with the frame piece 2, which forms a stop or abut ment, the adjustable lever 45 is shifted on its pivot 46 and the link 42 pulls the swing ing member 39 against the action of the spring 47 to shift the pivot 38 or" the pawl 36 so that the tooth v37 oi said pawl will, by engagement with the tooth bar 35, feed the carriage 32 a predetermined distance. When the carriage 15 begins its return movement, the spring 47, in returning the arnr43 to its normal position, will act on the swinging member 39 in the direction to shift the resilientlyheld pawl 36s0 thatthe tooth 37 will ride over the tooth bar 35..

The amount of the feeding of the carriage 32 may be determined by any suitable means. In this instance, there is provided an adjusting screw 49 which is mounted on the adjustable lever 45 and is adapted-to cov operate with a fixed stop or abutment 50 on the under side of the table or carriage 15. By adjusting this screw the movement of the adjustable lever 45 after engagement with the face 2 of the frame piece 2 may be varied, as the position of the arm 48 with reference to the carriage 15 is changed. There may also be employed, in connection with the feeding mechanismfor the carriage 32, an indicating means, which, in this instance, is in the form of a pointer 51 on the lever 45 operating in a slot 52 in the carriage to cooperate with, the scale or indications 53 on the top surface ot the carriage 15 adjacent the slot it is also preferred to employ in eonnection with the carriage32 a clutch or other back lash device which will prevent even the smallest amount of movement of the carriage 32 away from the cutter after each Feeding action. In this instance, this clutch is in the term of a cam surface 54 on a member pivoted at 55 on the carriage 15,'the cam surface 54 being adapted to cooperate with the carriage 32 to prevent the return of the latter while, at the same time, permitting the feeding of said carriage 32 to,-

ward the cutter. cam member 54 to maintain it in cooperation with the carriage 32 while, at the same time, permitting the yielding of said cam member when the carriage 32 is fed toward the cutter. g

Vfith the end in view of permit-ting the carriage 32 to be moved away from the cutter, a controlling rod 57 is employed, this red having a finger piece 58 through which it may be pulled and liaviiiur also a pivotal connection at 59 with the pawl 36 so that the latter may be disengaged from the rack bar 35 to permit the carriage being shifted by hand toward its starting position. In orderto control also the clutch or cam member 54, the rod 57 has connection through an arm 60 on said clutch member and a shoulder 61 on the rod through which the clutch member 54 is shifted out of engagement with the carriage 32 when the rod 57 is pulled to release the carriage t'rom'the pawl 36.

With the end in view of protecting the user of the machine against the rotary cutter 6, the latter may be provided witha guard 62 in the form of a segment of a ring which provides a space between its ends through which the knife may be engaged by the material on. the carriage 32. This ring segment is L shaped in a cross section so that it will cover the edge of the knife as well as the front face of said knife adjacent'the edge. In this instance, this guard is pivoted on a A spring 56 acts on this frame when the first mentionec That I claim as my invention and dcr-lirc.
