gear 5, mounted on shaft 4,. is arranged to.

intermesh with a driving gear 6, carried by a sleeve 7, mounted upon a fixed stud 8. A crank handle 9, suitably connected to gear 6 affords means for imparting rotation to shaft 4. By mounting the cutter or knife 2 upon an enlarged wheel 3, as above described, said wheel also serves the purpose-of a counterbalancing wheel, whereby the machine is steadied during the operation thereof, and is enabled to run more smoothly than would be the case otherwise.

Upon a stud 10, mounted in the main frame, is a rocking oke 11, in the upper ends of the arms of which are supported at one endthe rods 12, 13. At their other ends these rods are connected by a cross bar 14,, which is supported for vertical adjustment in any convenient manner, as, 'for instance, by means of a leg 15.. In the preferred form shown, the leg 15 is secured to-the cross-bar 1e by-means of a bolt 16, arranged to extend through the cross-bar and through a longitudinal slot 17, in the leg. By this construetion it will be seen that thecross-bar 14, and hence the ends of the rods 12, 13,-connected thereby, maybe raised and lowered as desired, the yoke support for the other ends of said rodsrocking upon the-stud 10 during such vertical adjustment. The rods 12, 13 are arranged to extend in parallel relation with res set to each. other and with respect to the ane of action of the rotary cutter 2, and a 0rd guiding supports for a reciprocatory table 19, said tab e carrying guide boxes 20 u on the under side thereof, through Whic the rods 12, 13 pass. Relative reci rocatory movements may. be imparted to t e table and rotary cutter in any convenient maimer. In the particular form shown, to which, however, my invention is not to be limited or restricted, and as above indicated, the table,19 is reciprocated, being sup ported and guidedby the rods 12, 13, and m a line parallel with the plane of action of the rotary cutter. Reciprocations may be imparted to the table 19 in many different ways. I have shown a simple. arrangement, as the preferred form, wherein I mount a crank arm 21, on the end of a shaft 22, suitably journaled in the framework, and I interpose a connecting rod or link 23 between,

the table 19 and said crank arm. As shown, one end .of said rod or link is pivotally connected to a block 24, secured to table 19, and

at the other end thereof is connected to the secure steadiness and easy working of the said stud being apparatus, the crank arm 21 may be counterweighted, as indicated at 27. Rotations may be imparted to shaft 22 in any conven-- ient way. In the preferred form shown, the shaft 22 is driven from.the same source from which the cutter is driven. As one form of driving gearing I have shown a sprocket chain 28, arranged to operate over.

pair of sprocket gears'aceording to t 'e speed required. If desired, and in order to maintain tautness in the sprocket chain, a s ringpressed belt tightener 33, may be emp oyed. This belt-tightener is pivotally mounted upon a convenient part of the framework so as to be rocked out of the way when it is desired to shift the s rocket chain 28 from one to the Otherset o sprockets. A 5 ring 34 serves to yieldingly maintain t e belttightener pressed against thes rocket chain when in operation, and the elt-tightener should be so constructed as to serve its pur poses whether the sprocket chain is on one or the other set of sprocket gears.

In suitable bearing boxes 35, 36, carried by table 19, is mounted a rod 37.

38 designates a table, platform ,or other support, mounted upon to move with table 19 during the reciprocatory-movements of the latter, but capable of movement along said table 19 transverse to the line of its reciprocatory movement. This table, platform or support 38, is provided with boxes-or bearings 39, 40, arranged to slide upon and to be guided by rod 37, as clearly shown in Fig. 1. The table or support 38 is provided witha rack 41, arranged to be engaged by a worm 42, said worm being mounted upon a stud 43, supported in bearings 44, 45,

carried-by tab e 19. Mounted upon stud 43 to rotate therewith is a ratchet wheel 46, (see Fig. 3). Loosely sleeved upon stud 43, and in inclosing relation with respect to ratchet wheel 46, is a casing47, from which extends an arm 48. The casing 47 is also provided with a barrel 49, in which is carried a pawl 50, arranged to cooperate with the teeth of ratchet wheel 46. If desired, and in order to maintain efficient engagement of the pawl 50 with the teeth of ratchet 46, a'spring 51 may be arranged within barrel 49, to exert its tension'upon pawl 50. The arrangement is such that when casing 47 is rotarily displaced in one direction the pawl 50 will ride loosely over the teeth of ratchet 46, but when said casing is rotarily displaced in the opposite direction the pawl 50 enga es the ratchet teeth of ratchet wheel 46 and imparts thereto a corresponding rotary movement. Ifdesired, and preferably, means may be provided for yieldingly maintaining the casing 47 in an initial position and serving to return or restore said casing to such position after it has been rotarily displaced. A convenient arrangement for accomplishing this object is shown, wherein a spring 52, is connected at one end to casing 47, and at the other end to an arm 53, in the form of an extensionfrom the bearing 45 of stud 43.

From the foregoing description it will be seen that by periodically engaging and rocking arm .48 of casing 47 from its initial or retracted position step by step, rotary movement will be imparted to ratchet wheel 46, and hence also to the worm 42, and since the worm 42 is in engagement with the rack 41 of table 38, it will be seen that said table is progressed or advanced.in a line transverse to the .line of reciprocatory movements imparted to table 19, While at the same time the table 38 partakes of the reciprocatory move ments of table 19. The periodic engagement of arm 48 to effect this operation may be accomplished in many specifically different Ways. I have shown a sim le arrangement, wherein I mount an adjusta le slide bar 54 in convenient position upon the frame of the machine to engage the arm 48 at the limit of each stroke or-reciprocatory movement of table 19.. By suita 1y adjusting the bar 54. toward and from the limit of movement of table 19, the degree and extent of rotary movement imparted to the worm 42 may be regulated.

preferred form wherein at the front end of table 38 I provide the upright-rack bars58, 59, upon which is adjustably mounted and guided for vertical movement a crossbar 60. This cross-bar cooperates with the correbars 60, 61, may

s ikes 62.-

spondin crossebar 61', supported or nesting upon ta hle38. If desired, and in order to afford an efficient clamping means, the crossbe provlded with teeth or The adjustable clamp-bar 60 carries spring- pressed'pawls 63, 64,-. at the respective ends thereof, respectively arranged to cooperate with the teeth of rack-bars 58,

59, the arrangement being such, that thecross-bar 60 may be readily lowered by eX- erting pressure thereon, the pawls 63, 64, in such event ridin over the teeth of rack-bars 58, 59, but said bar is prevented from being raised by reason of the engagement of the down upon the upper bar until it clamps with guiding supporting pawls with he teeth of the rack-bars without rst rocking said pawls out of engaging reiation Withrespect to the teeth of the rack.- bars. In this manner, the material to be sliced may be efliciently clamped and held by being laced in position upon the lower clamp-liar 61, the upper bar being sufliciently raised, and then simply pressing sufficient tightness against the article, in which position the clamp-bar 60 will be held by the pawls 63, 64.

The operation of the machine will be readily understood from the foregoing description, taken in connection with the accompanying drawings, and may be briefly stated as follows. The articleito be sliced or cut is placed in position upon the supporting platforms or tables, being, if desired, clamped thereon by the clamping bars 60, 61, of the upper table or plate 38, and projecting forwardly or toward the plane of action of the cutter over or upon the lower table or plate 19. The crank handle 9 is actuated, thereby imparting rotation to the cutter .2. At the same time rotation is imparted to shaft 22, through. which the crank arm 21 is rotated, thereby imparting reciprocations to the work-supporting tables 19 and 38, along the rods 12, 13, and in a direction parallel with the plane of action of the cutter, so as to carry the material to be sliced back and forth past the cutter. The speed of the reciprocatory movements thus imparted to the material may be varied with reference to the speed of action of the cutter, as above explained, by shifting the sprocket chain 28 from one to another of the sets of sprocket gears. This is im iortant, in that it enables the relative speed ormoven ent of the material with reference to the cutter to be varied according to the character of the material tobe sliced. At each reciprocation of the work-holder the end of adjustablecbar "54 is engaged by the arm 48 of the ratchet mechanism through which worm 42 is rota.- tively moved through'a given distance, de-

It will also be seen that the workholding table 38, with its strap or box guides 39, 40, operating in guide-rod 37, is permitted to be rocked upon such straps or guides so as to raise the rack-bar 41 thereof out of engagement with the worm 42, thereby enabling said table to be advanced or retracted by hand to any desired extent and then replaced in position with the worm 4-2 in engagement with the rack 41. It will also beseen that, I employ a comparatively large supporting wheel 3for the cutter 2.

This enables the cutter supporting wheel to serve also the purpose of a fly-wheel, thereby enabling the apparatus to be .run steadily and smoothly, and by providing the crank arm 21 with a counterbalancing projection 27, the ap aratus is caused to run more regularly ant smoothly during the operation thereof.
