Application tiled December 5,1898. Serial No. 698,340. (No model.) To a/,ZZ whom t may concern.- Be it known that I, FREDERICK P. RosBAcK, a citizen of the United States, residing at Chicago, Cook county, Illinois, have invented certain new and useful Improvements in Machines for Cutting Lozenges, of which the following is a specification. My invention relates to that class of ma cllines which are automatic in their arrangement and are used for formingaloaf of candydough into sheets and cutting lozenges of various shapes and sizes therefrom, and particularly to the means for ejecting the cut lozenges from the punches and delivering them onto proper boards. The object of the invention is to provide a simple;economical, and eiiicient machine for automatically forming and cutting lozeuges from a sheet of candy-dough and discharging them upon a board or similar element; and the invention consists in the features, combinations, and details of construction hereinafter described and claimed. In the accompanying drawings, Figure lis a side elevation of a portion of the machine; Fig. 2, a vertical elevation taken on the irregular line 2 of Fig. l; Figs. 3 and 4, side sectional views of a portion of the machine, taken on the line 3 of Fig. 2, showing the cutting and discharging mechanism in different positions; Fig. 5, an enlarged sectional elevation taken on the line 5 of Fig. 6; Fig. o', a transverse sectional plan View taken on the line 6 of Fig. 5; Fig. 7, a side sectional view showing a portion of the mechanism and taken on line 7 of Fig. 5; Fig. 8, a sectional view of one of the slides, taken on the line 8 of Fig. 7; and Fig. 9,a side elevation of the complete machine. In constructing a machine in accordance with my improvements I use a frame A of the desired size, shape, and strength to support and hold the operative parts in the desired position. This frame, as stated above, may be of any desired shape; but I prefer to make it in the shape of a rectangular open frame, as is shown in the drawings. To reduce a loaf of dough into asheet and feed it forward, several rolls are provided (not shown in detail) and mounted in the supplementary frame B. These rolls are provided With a train of gears B for the pur'- pose of giving the rolls the desired power and motion. To operate these rolls, a main driving-shaft C is provided and has a toothed pinion c, meshing with a gear C' on a supplementary shaft c'. This supplementary shaft is provided with a crank-plate D, having a cross-head slidingly mounted therein and which is provided with a connecting-rod d, engaging with an oscillating plate D', pivotally mounted on a second supplementary shaft d. This supplementary shaft d is pro vided with a spur-.gear E, to which is secured a ratchet e, with which a pawl e', pivotally connected with the oscillating plate, may be engaged, the parts being so arranged and timed that the revolutions of the main shaft act, through the mechanism above described, to oscillate the plate and moveltheyrolls forward in astep-by-step manner. During the movement of the rolls the candy-dough is forced between the same and is fed forward in the shape of sheet, so that it comes under the cutting mechanism. (Shown particularly in Figs. 3 and 4.) Fora fuller description as to the operation of the feeding-rolls, `the sizing of the sheet of dough, &c.,I would refer to my Patent No. 585,789, granted to me on the 6th day of July, A. D. 1897, in which such mechanism is fully described and claimed. To cut and form the dough into lozenges, provide a set of hollow punches G and mount them upon a cross-bar g, so that as the said punch crossjbar is moved up and down the punches are brought into contact with a piece of dough X to cut the same on the table Y. To move the cross-bar up and down, a pair of main slides H are slidingly mounted in the heads H and are given their sliding or reciprocating motions by means of eccentrics h and eccentric-rods h'. The eccentrics It are mounted upon the supplementary shaft c', from which they receive their power and mo.- tion. This punch crossbar is secured t0 what I term punch cross-barslides Lwhich are independently mounted in ways h2 of the main slides, so that they may move with such slide simultaneously orindependently,as may be desirable or necessary. When the main slides are having their upward stroke, it is necessary that these punch cross-bar slides too -moving farther at'the proper time. be moved simultaneously with it for at least a portion of its stroke and be prevented-from In order to accomplish this result, the punch crossbar slides are provided with one or more studs i, which project out through openings h3 into the main slide, so as to contact an adjustable pin z",which extends through the head-blocks, as is particularly shown in Fig. 5. From this gure it will be seen that when the main slide is moved forward a larger part of its Amotion the adjustable pin contacts the screw-stud and holds the punch cross-bar slides from further upward movement, which also arrests the upward movement of the punches. As above suggested and as shown in Fig. 3,the punches when at their lower limit of motion have pierced the sheet of dough X and cut the lozenges, and the lozenges so cut will be carried upward by the punches on their upward motion, the stripper X' preventing the sheet of dough from being pulled up. It is necessary, therefore, that some means beprovided to eject the cut lozenges at the proper time, and, as will more fully hereinafter appear, this ejecting process must be accomplished in a com parativelyshort space of time, so as to provide for ample time in whichto remove the cut lozenges and discharge them at the proper place. In order toeject the cut and formed lozenges from their punches, an ejector is provided, consistinf,r of a set of eject-ing-pistons 7c, one for each of the punches, as is particularly shown in Ejg.2, and each piston inserted within its hollow'punch. This ejector is secured to a second cross-bar K', which I term the ejector cross-bar, and which is also secured, as is shown in Fig. 5, to two second supplementary slides K, which are independently and movably mounted in the main slide H, and which for convenience I term ejector cross-bar slides. To move both of these supplementary and independently-movable punch and ejector cross-bar slides at the proper time, a primary set of springs L is inserted between the main slide and the punch cross-bar slides, as is shown particularly in Figs'. 3, 4t, and 5, while a second set of springs L' are inserted between the punch and ejector cross-bar slides, as is shown in the same figures. To secure the proper relation between these different sets of slides, an adjusting mechanism is provided, consisting of a stud M and loose pin m, a sleeve M', in which the stud and loose pin are inserted, and a set-screw m' in the end of the sleeve. The -stud has engagement with the punch crossbar slides and is inserted through an opening in 'the ejector cross-bar slides and up into the cylinder. The sleeve has an engagement with the ejector cross-bar slides and extends upwardly through an opening in the frame of the machine, so that its head m2 may contact the same. The springs above mentioned assist to keep the parts in their relative positions and to give all of such parts an upward movement during the upward stroke of the main slide. 'During the downward movementI ofthe parts the main slide contacts set-screw t', so as to carry the punch-slides and crossbar down with it and pierce the dough. The ejector cross-bar and its slides, with the ejector, areheld back a desired amount, as shown in Fig. 8, by means ot the coiled springs L'. During the rising motion it is necessary to ejecty the lozenges in as short a time as possible and when the parts are' at or near the upper limit of the upstroke. In order to accomplish this result, a pivotal leverN is provided'and pivotally mounted in a stud N', while a coiled spring n is used to hold the lever in its normal position. The main slide is provided with a block O, arranged in the path ot' the inner end n' of the lever, while the outer free end of the lever is arranged so as to cont-act a projection O' on the ejector crosssbar slides. As the parts approach the upper limit of their stroke the projection O contacts the inner free end of the swinging lever and moves it up, while its outer free end contacts'the ejector cross-bar slides and forces the same downwardly in an accelerated manner, so as to force the ejectors downwardly-in the hollow punches and discharge the lozenges. It is desirable that some means be provided to limit the downward. movement of the ejector orto move the ejector and punches down simultaneously, so that the ejecting-pistons will not pass the lower end of the punches to come in contact with the punch ends and dull the cutting edges of the same. In order to accomplish this result, theslud M, sleeve M', loose pin m, and set screw m', above described, are provided. During the downward movement of the ejector-slide the sleeve M' is carried with it, so that as it approaches its desired limit the set-screw m' contacts the loose pin m, which in turn impinges against the stud M and carries the punch cross-bar slides and cross-bar with it during the remaining part of its motion. It is necessary that means be provided for catching the ejected lozenges and discharging them on a proper delivery mechanism. In order to provide suitable mechanism for this purpose, a rock-shaft P is provided, upon which is mounted what I term a dumpingplate jp, so arranged that it may be brought under the punches, as shown in Fig. 4, for the purpose of receiving the discharged Vlozenges, or tilted into the position shown in Fig. 3 for the purpose of dumping the cut lozenges onto a delivery-belt Q. To assist in dumping the lozenges upon the discharging-belt, a scraper P' is provided, which is formed ot' ends and sides p2, but has no bottom portion. This scraper is loosely mounted upon the rock-shaft by means of the arms 103, so that when the rock-shaft is oscillated to near the limit of its motion the parts are in their closed position, asshown in Fig. 4, and when the rock-shaft is moving'to the IOC IIO other limit of its motion the parts are in their open or dumping position, as shown in Fig. 3. To `give the dumping mechanism its necessary movements, the rock-shaft is provided with aslotted arm R, connected with a pi voted operating-lever R' by means of the link r. 'lhis operating-lever is connected with the main slide by means of a screw S, which eX- tends through a slot s in the operating-leverv The arms of the scraper, as above stated, are loosely mounted on the rock-shaft, and in order to assist in giving them their movements a pair of helically-coiled springs p4are provided, which have one end engaging with collars p5 on the rock-shaft and the other end engaging with the arms of the scraper. The arms of the scraper h'ave also oppositely-projecting ends P2, adapted to contact the trame of the machine. The operation of the dumping apparatusis as follows: Vhen the main slide is moved upwardly, the operating-lever is also moved upwardly and the crank-shaft is oscillated in the direction to bring the dumping mechanism `in a closed condition under the punches to receive the ejected lozenges, as shown in Fig. a. During the downward movement of the main slide the rock-shaft, by means of the operating-lever, is oscillated in the reverse direction, the helically-coiled springs move the scraper back simultaneously with the dumping-plate, and continue such movement until the arms P2 contact the frame of the machine, when the further movement of the scraper is arrested. The continuing movement separates the parts, so that the heel of the scraper strikes the lozenges while the dum ping-plate is in an inclined position, thus assisting in discharging the lozenges onto the delivery-belt. During the forward movement of the dumping-plate it contacts a lng p on the scraper and carries such scraper forward with it in aelosed manner, as shown in Fig. 4. The lzenges on the delivery-belt Q, by means of the movement of such belt, are carried forward until they fall over and are delivered on the boards T, (shown in Fig. 9,) the boards being moved forward step by step by means of the chain t, which is passed around suitable sprockets t and t2 and which are given their movement by means of the sprockets T', T2, T3, and T", the sprocket-belts Sand t4, which in turn are operated by means ot' the shaft U and belt U', which passes around the drum U2, such drum being driven by the belt U and the drum (not shown) on the shaft Z. i I claiml.
