To z whom it may concern,.-

Be tknown that we, FREDERICK W. BAUER and'JOHN C. IIEILMANN, Jr., citizens of the United States, and residents of Cincinnati, Ilamilton county, State of Ohio, have invented certain new and usefullmprovements in Candy-Forming'Machines; and we do declare the following tobe a clear,full,and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, attention being called to the accompanying three sheets of drawings, with the reference-numerals marked thereon, which form a part of this specification. y

This invention relates to machines which form substances in plas-tie or dough-like con` dition into pieces of uniform size and shape by rolling a separat-e piece of such mass between two surfaces, one of which is contained on a molding or forming wheel, and therefore the shape of the piece is limited to such forms which may be produced by rolling-as, for instance, balls, ovoids, cylinders, ellipsoids,

cones, (the rolling beingin this case aboutv their major axis,) dac. One of the applications for which it is particularly well adapted is in connection with the manufacture of confectionery and bakery goods, and it is mainly intended for such purpose.

This invention relates to certain features of construction and additional .auxiliary adjuncts, all of which are described in the following specification and particularly pointed out in the claims, together with its operation, parts, and construction, which latter is also illustrated in the accompanying three sheets of drawings, in whicl Figures 1 and 2 are side and top views of the machine complete with the remote part of the track removed. Fig. 3 is an end view of the machine, showing its discharge end with the track in section. Fig. 4 in a similar view shows'the end of the machine opposite to the one illustrated in the previous figure. lfig. 5 shows a top View of the track and parts supported thereon. Figs. 6, 7, and 8 are sectional detail views and show the machine adjusted to form work of different shape.

In the drawings, 11 indicates the receiver, substantially of cylindrical shape, which contains the dough, the ,same being supplied through a hopper l2. One end of it is shaped to form a flat cone, the apex of which contains the discharge-opening 13. A screw 14 occupies the cylindrical body of receiver 11, being mounted at the end of a shaft 15, which is supported in bearings, one designated by 16, formed in one end of receiver 11, and the other formed in a standard 17. The rotation of this screw forces the plastic mass out through the discharge-openin g, from which it issues in an unbroken body, being, however, divided at once by a rotating knife-blade 18, which at certain regular intervals passes through it immediately outside of the discharge-opening. Since a fixed ratio obtains at a time between the operations of this knife and the rotation of feed-screw 14, which ratio may, however, be adjusted, it follows that the cut-off pieces are all of equal size. These pieces drop at once int-o the forming device, which consists oftwo parts, complementary to each other and each containing one-half of the surface necessary reproduce the particular shape. One of the halves of this forming-surface is contained in a stationary part, (indicated by 19,) while the other surface, which moves past the surface first mentioned, is contained in the face of wheel 21, mounted on shaft 22, whereby it is rotated and which is supported in bearings formed in standards 23 and 24. The shape to be produced in this case being a ball the surfaces are shaped accordingly, each forming a semicircular trough, of which one is contained in the face of wheel 21, while the other is contained 'in member 19, which is closely fitted against the periphery of said wheel and, starting in a horizontal plane below or in line with the discharge-opening 13 to bring this open end of the forming-surfaces in ready position to receive the cut-off piece, follows the wheel for about one-fourth of its circumference-that is, suicent to bring the discharge-opening of the forming device in'to a vertical plane, as indicated by 25. Upwardly toward the discharge-opening 13 of the receiver this member 19 spreads somewhat, assuming a shape reselnbling a funnel, open, however, toward the face of wheel 21 and toward opening 13. This funnebshaped part receives the pieces separated by the knife, which are gradually compressed and rolled int-o the shape of a ball by the ac- ICO . rial used to discharge.

tion of wheel 2l, rotating in the direction of the arrow and moving its forming-surface against and past the forming-surface contained in the stationary member 19. Since these two forming-surfaces have together assumed at and back of dischargeopening 25 the shape of a tube the diameter of whichl equals the diameter of. the balls to be produced, it follows that the desired end is readily attained and the balls discharged are all of the required size.

To facilitate the rolling operation and prey vent adherence of the mass to the formingsurfaces, a sprinkling device is provided, consistin g of a suitable receptacle 26, having perforations in its bottom, and a rotating agitator 27 in the lower part, which causes the mate- It is so located that the material used (powdered starch or flour) drops upon the forming-surface contained on wheel 21 and is therefore secured above the latter, being supported on a bracket 28, resting on and connected on top of standard 23. The formed pieces discharged at 25 are kept separated for some time to permit them to harden suiiciently to prevent sticking to each other, for which purpose they discharge upon a tray, which is so moved that the balls are deposited in rows thereonto, one dropping beside the other previously-discharged one. In the drawings 29 indicates this tray, which may have grooves in its upper surface to prevent the balls from rolling awayfron"their proper position, which keeps them separated. This tray rests on a slide or sliding frame 31, which latter is again supported on a carriage 32, moving on track-rails 33 34. This carriage, with all parts supported on it, has a reciprocatory longitudinal movement in line with the machine-that is, to and from the latter-which causes the balls to be deposited i-n rows,since the tray between each discharge has been moved a certain distance sufficient Ato keep the balls separated from each other.

At the end of each of the movements of the carriage th-e slide 31, resting on it, is moved laterallythat is, at right angles to the movement of the carriage-the object of this movement being to start a new row beside the previously-filled one. After a tray has been filled the operation of the machine may be interrupted until an empty one has been substituted.

The formed pieces discharging from opening 25 could drop directly'onto the tray, in which case, however, it would be necessary that all or at leastt-he larger part of the carriage move under the machine-table. Since this is not practicable, l1owever,on account of the support and legs of the machine-frame being in the way, the balls discharge first upon a belt 35, by which they are carried far enough out to reach the remote end of the tray when the carriage is at the end of its in- Ward movement-thatis,nearest the machine. This belt is supported on a bracket-arm 36, projecting from leg 37, to which it is connected, and may have flanges projecting up- Wardly above the edges of the belt, as shown in dotted lines in Fig. 1, to prevent the balls from rolling oft sidewise before reaching the outer end of the belt,where they drop olf onto the tray immediately underneath. The following is a description of the mechanical means whereby all these functions are carried out:`

Shaft 22, upon which wheel 2l is mounted, is rotated `by a gear-train 38, actuated by a shaft 39, supported in bearings which are also formed in Astandards 23 and v24 4and are 1ocated above the bearings for shaft 22. Shaft 39 is rotated by a bevel-wheel train 41, Iwhich is actuated by a shaft 42, supported in bearings formed in standards 43 and 17. This shaft 42 is parallel to shaft 15, which operates the feed-screw, and has also mounted upon it a hub 44, which contains a short arm, affording means to secure the knife-blade 18, which latter receives thus its rotary movement. One or two of them may be used, according to the size desired for the pieces supplied to the forming device, it being evident that with two knives the mass issuing from openingvl is cut in more rapid succession, producing smaller pieces. The motion of shafts 42 and l5 is made dependent on each other, for which purpose they are connected by a gear-train 45, and one constitutes the drivingshaft for the other. If power is used, a driving-pulley of proper size may be mounted upon either shaft. If hand-power is used, a crank 4G is applied either directly to shaft -42 or to an extra shaft 47, supported in bearings, one formed in standard 17 and the other in an independent standard 48. A gear-train 49 provides operative connection between these two shafts 47 and v42. Gear-train 45 between shafts 42 and 15 may be arranged to permit adjustment of the speed transmitted. In this case provision is made for three speedchanges, for which purpose the gear-wheels carried on shaft 15 are loosely mounted, but may by means of a sliding key projecting through a slot in shaft 15 be locked to shaft 15, one, however, only at a time, so that shaft 15 is then for the time being actuated by a particular wheel and ata certain speed. This sliding key is carried by a rod 50, occupying a bore in shaft 15, the key projecting out through a slot in the latter, as stated before. Bymea'ns of a spring 51, the end of which ongages with notches in rod 50, the latter, with the key, is held in its adjusted position. Any `other suitable speed-changer and adjusting device may be used here. The agitator 27 of the sprinkling device is actuated by a gear# train 52, connecting the shaft 53 of the former with shaft 39. Belt is operated by a pulley 54 on shaft 55, a pulley 56 on which is rotated by a belt 57 from a pulley 5S on shaft im.

59 and (il are merely guidepulleys for belt 35. I

For purposes of reciprocating the carriage a chain G2 is used, supported onand guided IODl IOS

by chain-wheels 63, the bearings of which may be preferably secured te the under side of one of the track-timbers, (34 in this case.) Motion is obtained by rotating one ofthe chain-wheels, which is done by mounting a belt-pulley 64 on the shaft of one of them, which belt-pulley is drivenV by means'of a belt 65 from a pulley 66 on shaft 55. The connection to the carriage is by means of a pin 67, carried by the chain, from which it laterally projects and occupies aslot in bracket 68, secured to the carriage and projecting downwardly therefrom. The operation is readily understood. The pin as it is carried forward and` backward by the chain simply takes the carriage with it, moving at the turning-points up and down in the slot of bracket 68. Since delivery from belt 35 proceeds continually, it follows that for each motion of the .carriage, outwardly as well as inwardly, a row of balls is deposited on the tray'. In order to prevent,v however,'the rows from being delivered on top'of each other, the tray is moved laterally at each of the points where the motion of the carriage reverses, the movement being sufficient to 'bring the filled rows away from underthe delivery, advancing a clear space under the latter. This is done by shifting each .time at those points the sliding frame 31, upon which the tray rests, a sufficient distance sidewise,which is accomplished by the following construction:

69are pawls pivotally supported on the inside of track-timber 33., 71 are stops engaging with that part of these pawls which is below their pivotal supportsin such manner that they are capable of yielding and swinging with their upper end in one direction only. 72 is a disk mounted on a shaft 73, which is supported kin bearings 74, projecting from a timber 7 5, which forms a part of the carriage. A number of pins 76, circularly disposed, project Afrom the side of the disk, all these parts being so located that the upper end of pawls 69 reach within the path of the loweron'es of these pins. The effect of the action when these parts engage may be seen best in Fig.. 1, Where the carriage coming inwardly -is arriving at the end of this part of its movement. A row of balls has been de. livered onto the tray above, and before starting outwardly again it becomes necessary that the latter be shifted, for reasons previously mentioned. The inner pawl 69 (shown in Fig. 1) is therefore so located that when the carriage has moved in the lowermost one of pins 76 has alsoA passed against and beyond the upper par-t of it, the pawl having yielded and dropped back again into its normal position, as shown in dotted lines. ln said figure the piu is shown in the act of passing over the pawl,the latter being tipped at this moment. On moving outwardly this same pin comes again in contact with the pawl, striking it from the other side; but since the latter cannot yield in this direction by reason of stop 71 it follows that disk 72 must turn in order to permit its pin ymoves at every one of its rotations.

to clear the pawl. This partial rotation of disk 72 also rotates its shaft 73, which rotation is transmitted to a shaft 76 by means of an interposed gear-train 77. Shaft 76 is supported and has mounted upon its other end a cogwheel 78, which rotates with shaft 76 and by meshing into a rack 79, secured to the under side of sliding frame 31, shifts the latter, with 'the tray on top, through the required distance. vInterposed rollers 81 on top of the carriage serve to reduce the friction of sliding frame 31 while so moving. Another pawl 69 is vlocated farther out on track 33 and in such position thereon that it is also encountered by one of the pins of disk 72 at the time when carriage 32 is-appi'oaching the end of its outward movement, so that when it starts inwardly again the. tray is shifted again to make room for another row of ballswhich is delivered beside the row deposited previously while the' carriage was moving outwardly. When the tray has been completely filled with rows by its full outward movement on the carriage, the operation of the machine is interrupted until an empty tray has been substituted, after whichv the slidingl frame is pushed back to a position shown in Fig. 3 and operations resumed.

In order to keep the knife-bladeclean, a water-tank 82' is provided, through which it Brushes 83 are provided, between which-it passes after having dipped into the water.

,The inside of receiver 11 may be shaped to form ridges 84, which act as a means of resistance by retarding the dough, which has a tendency to move around with the rotating screw instead of advancing 'thereon for the purpose of passing out.

In Figs. 6, 7, and 8 the capacity of the machine for producing other shapes is shown. Itis done by substituting for members 19 and `21 other similar members, but with different forming-surfaces.
