SPECIFICATION forming part of Relssued Letters Patent No. 10,691, dated February 23. 1888.

Original N0. nears, emu May =19, 1883. Applicut To all whom it may concern.-

Be it known that I, IlrIARTIN DE TAMBLE, of Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Cake, Jumble, and Snap Machines, of which the following isa specification.

The object I have in view is to produce a soft-dough machine of the class having wire knives working with four movements, which machine will be simpler and more efiicient can be operated with less power, will be subject to less strain, and be more durable in use, and will be adapted for making cream bars as well as ill other kinds of cakes, j umbles, and snaps.

My invention therein consists in the several peculiar devices and combinations of devices employed by me for this purpose, as fully hereinafter explained, and pointed out by the In the accompanying drawings, forming a part hereof, Figure I is a side elevation of the machine, Fig. II, an elevation from the opposite side; Fig. III, a vertical longitudinal sec-- tion through the center'of the machine; Fig.- IV, a vertical cross-section taken in front of the sliding knife-frame and the dough-box on line 4; Fig. V, a perspective view of the adu just-able bearing-block for the cross-bar of the sliding knife-frame; Fig. VI, a vertical section through such bearing-block; Fig. VII, a perspective view of the other sliding bearingblock of the knife-frame; Fig. VIII, a per.-,

spective view of the end arm of the knifeframe and of the end of one of the other arms; Fig. IX, a view of the dog'arm of I the knife frame; Fig. X, a view of the dog and a part of its supporting-bar, and Fig. XI a detached and the 'dog when such frame is being retracted.

Like letters denote corresponding parts.

A is the main frame of the machine, from the sides of which rise the uprights B B, be tween which the dough box 0 is secured. This dough-box is raised above the horizontal frame A, and has the cup-plate a, provided with openings or cups through which the dough is forced, removably secured in its bottom by sliding into dovetail ways in the botion air reissue 5101] my 29, 1885. ScrialNo.16T,082. I

hung from a horizontal shaft, E, jonrnaled in boxes in the uprights, B B, and are revolved by such shaft through bevel-gears 0. One end of the shaft E receives a hand-crank by which the follower is raised, while the otherend of such shaft, outside ofthe upright -B, has mounted loosely upon it the cog-wheel F. The hub of this cogwheel on its in vided with clutch-teethd, which engage with. the teeth of a sliding clutch-sleeve, G, feathered 0n the shaft E. This sliding clutch is thrown into and out of connection with the teeth dby a lever, H, which projects inwardly through the standard B above the follower.

A beveled block, e, is secured to the side of the nearest screw-socket D at the upper end thereof,' which block lever H when the follower has reached the bottom of the dough-box.and throwsthe clutch out of connection with the teeth of the hub of the cogwheel in time to prevent the follower from being forced through the bottom of the doughbox. I do not, however, claim in this application the automatic device for uncoupling the follower from the driving mechanism, since I propose to make a separate application for patent on'the same.

The cog-wheel F meshes with a pinion, F, below it, which is mounted on a spindle adjust-- able in a curved slot formed in a plate, f, supported from the outside of the standard B.

The pinion F can be removed from the machine and a larger or smaller pinion substituted for it, so that the speed of the follower can be changed as desired, the slotted plate f permitting the adjustment required for the different-sized pinions.

Secured to the pinion F, so as to turn therewith, is a sprocket-wheel, F, which is revolved by a driving-chain, F, from the wheel F on the'driving-shaft G. The slot in the plate f is formed on the curve of-a circle struck from the center of the shaft G, so that the change in sockets D, secured to the follower, and are strikes the end of the dough-box has a sliding cut-off, b, for closing ner side isproin size of the'pinion F will not affect the driv- I00 5 the position of the sliding llliib'fl'il-"IC can be ing-chain. The driving-shaft G hasa pulley, G, to which the power that operates the machine is applied.

gears, and screws described the follower will be given a continuous even movement, winch is independent of the other movements of the machine, and can be readily changed in speedwithout necessitating a corresponding change of the other movements. To the other end of the driving-shaft is secured a crank, g. which is connected by a rod, g',with a horizontal arm, 9', projecting from-a rock-shaft, h, journaled transverselyin the lower part of the main frame. This rock-shaft has two vertical arms, 1' i'one at each cnd-which at; their upper ends are connected by rodsi i with the sliding blocks-I l of the luiil'c-fran1e. These blocks work in ways I I, and carry theknitcframe, as will be presently described; A positive horizontal, sliding movement back and forth is imparted to the blocks I I. by means of the rocking connection wit-lithe drivingshal't. The pitman-rod g is adjustably connected with the horizontal rock-arm 9', so that regulated. To provide for this adjustment the rod g passes loosely through a collar,'j, pivoted in the forked end of the. rock-arm g,

and has nuts j both above and below suchcollar, which turn on a screw-thread out on such rod 9.

In the sliding blocks I I is journaled the crossbar K of the knife-frame, the ends of such bar projecting outwardly through the b locks for. making connection with the rods 2" z trically through a turning box, 7., which has a handle, k, and is held at any point of adj list-- ment by a bolt, k which connects the handle with a curved slot, Ir", formed in'au upward extension of thoblock I, as shown in Fig. V. By journaling the cross-bar K in an eccentric at one end, such cross-bat" can be raised and lowered at that end by turning the eccentric, and this enables the wire knife to-b'e adjusted so that it will bear equally on all the cups of the dough box. I

In tilting the blocks I I in the ways I I, and in boring such blocks, the result will be more or less inaccurate. and the cross-bar K will not be exact l v parallel with the cup-plate,

and consequentlythe wire knife will not bear equally on thee-ups. It is essential for the successful, working ofthc machine that the wire knife should hearon all the cups alike, and by adjusting the height of the bar K at one end this can be accomplished. i

To the crossbar K are secured the arms L L, which carry the wire knife M on their'ends. These arms project from the bar K to a pointunder the dough-box, and are secured to'sueh bar by set screws Z, so that they can .be adjusted thereon. V

In the operation of the machine, it is neces sary that the knifearms should be arranged to move one between each pair of dough-cups,

In the block I the bar K passes eccen-.

,andsinee the cups of...t he various cup-plates used in the machine are of different size and e V I number, it becomes necessary, in chaugin g the It will beseen that through the chain, wheels,

opp-plate, to adjust the knife-arms laterally on t'he cross-bar. \Vhcn there are more arms than required, thesupertluous arms are pushed together close to one end of the crossbar; The cross-bar is made angular in cross-section,

or is provided with a feather, the purpose of which construction is to always keep the arms at the same height, so that the baker will have no trouble to preserve the vertical adjustment of the arms when he finds it necessary to shift them laterally.

The wire knife is secured to the endarnnL', nearcstthe block I, and is passed through loop Z'on the ends of the'intermediate arms, L, Figs. VIII and XI. It then passes over a pin, Z, on the end arm, L. and around a turningstud, I, carried by such arm. The stud l is held in one direction by a spring-pawl, I, engaging with ratchet-teeth on the stud, so that by turn ing such stud the wire knife can be given any desired tension. The arms L L are thrown upwardly to bring the wire knife in the right position for cutting the dough hanging from the cup by means of a spiral spring, N,which is sleeved on a belt, at, secured in an upwardand rearward extension, at, of -t he arms L, and sliding through an arm, a, rising from the block I. lhis spring presses the extensionn backw'ardand downward, and raises the ends of the arms'and the wire knife.

The upward movement of the wire knife is governed by a set-screw, 0, which turns in a lug, 0', on'th'e rearward extension of the arm L, and sets against the sliding block I. v This set-screw may be provided with a jamnut above the lug o',-l'or holding itat any point of adjustment.

To tlie'cross-bar K is also secured the dogarm which projects therefrom in the same direetipn asthe knife-arms, but above the level of such knife-arms. This dog-arm is curved upwardly, as shown, and then exteudshorizontally to its end to form a hearing for the pivoted dog I. This dog is pivoted to the lower cnd'of a block, 1", so that it can swing past a vertical line only in one direction. and such dog is drawn back into a vertical position, whenswuug on its pivot,by aspriug, p. The block P is supportedby a slotted bar, Q, and has a nut sliding in the slot of such bar. The bar Q is pivoted at one end by a bolt, q. to the outside of the standard B, and near its centerhas an'npwardly-projecting slotted.

finger, q, through which a. holding-screw. q", turns into a hole in the standard 15'." This arrangementpermits a vertical adjustment of the dog.

A screw, Q, turns through the nutou the block P','and furnishes the means for adjusting the pivoted dog horizontally. In theforward movement of the knife-arms the spring 7 N holds the knife close up to the dough-cups, and the dog P is swung forward on its pivot by the arm 0. \Vhcn, however, the raised portion of the arm has passed the pivoted dog, such dog is drawn into a vertical position by its spring, and in the return movement of the knife the arm 0 will be forced downwardly by the dog, and will carry with it the other arms and the wire knife.- ---There is thus given to the wire knife'the four movements necessary for the successful operation of the machine-via, a forward, movement on the level with the cups to cut oil the dough, a downward movement, a return movement below the-cups, so as 'toavoid the dough, and an upward movement to the first. position. These movements are accomplished in my machine by means which are certain andefiicient in their action, and which can be operated with less power than required by the machines heretofore constructed for this. purpose.

The wire cutting knife, it will be seen, i given a horizontal sliding movement below the level of the cups and a vertical movement at each end of its horizontal movement.- Itism for feeding table, S, over'which the apron travels. table at the forward a is operated by a belt-connection moves inthedirection of the travel of the feed-apron and cuts square across all the cups atthe same time. This knife is not liable to be broken, and workswith the minimum amount of friction and strain,.and cuts the dough clean from the cups. The mechanthe follower in the doughbox is independentof the knife-frame, and gives such follower a. continuous feed, thus adapting the machine for making cream bars as well as all other kinds of cakes and snaps. .The speed of the .follower-feeding mechanism can also be changed without interfering with the movement of the knife-frame.

R is theendlessapron of the machine, which carries the pans. This apron egtends over the operating-roller r at one end of the main frame, and over a roller. r, in the other end, which is journaled in sliding boxes adjustable by screws 1'. The shaft of the operatingroller has mounted on one end a stepped pulley. s, which is revolved by a belt from a stepped pulley, s, jonrnaled on a stud secured to the lowerpart of the frame A. The pulley with a pulley fixed on.the driving-shaft G. a is mounted loosely on the shaft of the roller r, and is connected therewith, so as to drive theroller by a pawl and ratchet. (Notshown.) The other end of the roller-shaft has abandwheel, t, by which theapron can be advanced at any time in order to prevent the dropping of the cakes on the edges of the pans.

Under the upper side of the apron is a This end of the machine is supported on. a cross-rod, u, to which it is pivotally secured by eye-straps, as shown. At its other end the table Srests' upon wipers v, which are work ed by a hand-lever, w. This hand-lever is held at any point of its movement by a bolt and slotted plate. By moving the wipers the table S can be raised and low cred at one end.

' In handling the harder kinds of soft doughagainst the bottom of ,with the fol lower,

The pulleyas,;for instance, snap-dough -it is necessary that theapronshould travel closer to thecups over unless theapron is close up to thecups.

In my machine the snaps are further prevented from alighting wrong side up by the upward inclination of the apron when raised at one end. Th 18 presents an inclined surface for the snaps to strike, so that when the snaps strike on their edges they will fall back, rather than turn over'in a forward direction.

v It is evident that many of the devices machine could be changed somewhat-in detail and stillaccom plish the same result.

It will be observ ed'that my cutting wire or knife is brought or passed under the dough-. box by the forward movement of the sliding frame, and in such a way as to press upsnugly the cups at every point as it slides or passes under them, and in .this respect it differs from the Vailand similar machines, in which the cutting-wire is brought around to and under the dough-box by a swinging or circular movement, which prevents it from coming or pressing up closely against the bottom of the cups, except at their front and back sides, and thus renders it impracti' cal and useless-"in the cutting of large cakes.
