BATTER-FEEDING- MECHANISM FOR ICE-CREAM-CONE-MANUFACTURING APPARATUS.

Specification of Letters Patent.

Patented July 15, 1919.

Original application filed October 19, 1917, Serial No. 197,502. Divided and this application filed September 4 To all whom it may concern:

Be it known that I, LEWIS LEWISON, of the city of Hamilton, county of \Ventworth, Province of Ontario, Canada, have invented certain new and useful Improvements in Batter Feeding Mechanism for Ice Cream- Cone-Manufacturing Apparatus, of which the following is a specification.

The invention disclosed herein relates to apparatus for feeding batter into the molds of a machine such as described and shown in my co-pending. application No. 197502, filed October 19th, 1917, of which this present application is a division, and my object is to devise a'batter-feeding device which is readily placed in position or removed from the machine, which is easily disassembled and cleaned, and which is adapted for coiiperation with the molds so that no batter is fed to a mold unless the mold is properly closed and locked.

I attain my object by means of the constructions hereinafter described and illustrated in the accompanying drawings in which Figure 1 is a side elevation of the batter feeding mechanism with a mold in position underneath the same t Fig. 2 an end elevation of the parts shown in Fig. 1;

Fig. 3 is a side elevation of the batter feeding device removed from its supports;

indicate corresponding parts in the difi'erent figures.

The machine with which my batter feeding device will usually be employed is of the ordinary type in which separable molds having cores cooperating therewith are moved past a batter feeding device.

The form of the mold forms no part of the present invention, but as the lock therefor is used to actuate the batter feeding device a mold is shown in Figs. 1, 2 and 10 of the drawings.

Referring particularly to Fig. 1, 4 is a. 1'0- tary carrier or disk on which the molds are carried. While my batter-feeding device may be used to fill any form of mold, the mold shown is especially adapted for coiiperation with my batter feeding device. In my construction each mold and core unit comprises the following parts: Each mold is formed of a pair of separable sections 13 connected to arms 14 provided at their ends with the engaging hinge knuckles 15. 16 is a yoke-' shaped bracket embracing the hinge knuckles 15. This bracket is secured to the carrier by means of a screw 17 and also by means of a hinge pin 18, which extends through the jaws of the bracket, through the hinge knuckles 15 and through the carrier, being secured underneath by means of a nut and above the upper jaw of the bracket by a pin 19.

The mold sections are preferably formed with a plurality of mold recesses with which cooperate the cores 20 secured to the core arm 21, which arm is hinged behind the hinge pin 18 on lugs 22 formed on the bracket 16. From this arrangement'it follows that by the removal of onescrew and a nut, a mold and core unit is quickly and easily removed or replaced whenever necessary. At the same time the arrangement of the yoke-shaped bracket always maintains the parts connected therewith in proper relationship, and the mold arms are as short as possible, which tends to prevent them springing.

To assist in the proper alin'ement of the cores and molds, I prefer to continue the hinge pin upwardly as shown and to form the core arm with a slot 23 embracing the hinge pin. The hinge pin also serves for the attachment of one end of'one or more counterbalancing springs 2%, the other ends of which are secured to the arm 21.

The hinge pins 18 also serve to support the locking levers Each locking lever is preferably forked to embrace thehinge pin to which it is pivoted at its upper end.

One end of each locking lever is provided with a projection 26 preferably formed as a roller adapted to engage in a slight in dent-ation formed at the upper end of the arm 27 secured to the core arm. The other end is adapted for engagement by looking or unlocking cams and is also preferably formed as a roller 28.

The cores are raised to the position shown in Fig. 1 by means of the cam 31 suitably supported from parts not shown. This cam is adapted to engage over the projection 32,

preferably formed as an anti-friction roller and secured to the heel of the core arm 21 behind its hinge. The mold sections are normally pressed to the closed position by means of springs (not shown), and are opened to the position shown in 2 by special opening mechanism (not shown), the opening and closing means forming no part of the present invention The mold sections must he firmly tightened together and locked closed during filling of the molds and the cooking of cones. It is also very desirable that locks be so arranged that the mold sect are not forced together in the event t broken cone or other obstruction bet' rieen the parts, or otherw 1 sections enclosing mechanism broken. lit is also very important that-l. batter shall be fed to a mold which has not been properly closed. To accony h desired results 1 provide the following mechanism.

On one section of? each mold is pivoted a hook-shaped lock which is adapted engage over a pin A on the coiiperz mold section. The hook is so shaped the. will normally tend to {all to the preliminary closing posit-ion as shown in 11, w t slight shoulder 73 resting against the pin 4 requiring the application or force to press the lock to the final closing position and jam the sections closely together, This force is applied through the medium oi a stationary care :5 supported from the frame of the machine in such a position that, tr e mold travels toward it, it will engage, according to circumstances, either below or shove the center of a projection to on the lock, prefieraloly formed as an anti-friction roller. It the lock has fallen to the prclimins locking position, as it will if there are rsoasea obstructions in the mold, the end of the cam will strike the roller just above. the center and draw down the hook, thus tightly jamming the sections of the mold together. If there is any obstruction in the mold, the sections will be held apart, against the tension of" the closing-springs, and the lock will fail to fall to the preliminary looking position, as shown in Fig. 10, in which case the can: if) will either strike the roller below the center or pass completely beneath it, so that the lock is not actuated to force the sections together, and thus no breakage of the mold or locking mechanism will occur, due to the parts being forced together with an obstruction between them.

The locks 43 are also used to actuate the hatter-feeding device, the projection 47 being formed for that purpose. /Vhen' a mold is properly locked, this projection occupies the position shown particularly in Fig. 2, in which position it will engage and operate the hatter-feeding device. if the mold be not completely closed, the projection l7 will occupy the position shown in Fig. 10, in which it will not operate the hatter-feeding device as will hereafter appear. The hatter-feeding device comprises a cyli icai casing a8 and the cylindrical hatter-measuring device and valve 429 rotatable therein. The casing is provided with a 1" 50 at each side adapted to be inserted in the grooved guides 51 formed at the lower end of the inwardly and downprojecting arms 52 extending from erm-ed on or secured to the 18. From the support 53 t-With the free end. of e 1-9 engages when the Y in the position valve being thus held when the casing is uides A set screw J vided "for clamping one J 50 in its grooved guide,

ogeinent it follows that the ice is readily placed. in si ion red from the machine and shied in a few moments for cleaning nunicatesby means of with the hopper 55, 3 provided with a source of hatter s plurality of mold d in each mold, a p-urality of inlet 3'?" may he employed inthe top of e casing communicating the though it is not essential to so sepaand ap'lurality of discharge openare provided in bottom of the cut-off of the batter and prevents drip.

From this arrangement it follows that the pockets are alternately filled and emptied as the valve is rotated, and as the filling and emptying occur during periods of movement, ample time is provided for proper filling and sufficient draining of the radial pockets followed by a cut-off of the drip before a fresh pocket arrives at the discharge position.

The end of the valve has a plurality of dogs 61, corresponding in number to the radial pockets, pivoted thereon. The movement of each dog in the direction of rotation is, however, limited by the stops 62. When a mold approaches the batter-feeding device, (see Fig. 2), the projection 47 and its lock, assuming the mold to be properly locked, will engage one of the dogs 61, press it against the stop 62 and then rotate the valve so that by the time the mold comes to a rest, it is immediately below the discharge openings 58 and one of the sets of radial pockets is in position to discharge through the discharge openings of the casing. If the mold is not properly locked, the projection passes by without engaging the proper dog to rotate the valve and no batter is fed, (see Fig. 10).

From the above description it will be seen that-as each mold in turn reaches the batter feeding device, it is filled as long as evervthing is going well. If, however, any mold becomes obstructed, the safety devices hereinbefore described come into operation and the machine makes no attempt to close the obstructed mold and no batter .is fed thereto.

It is desirable at times to be able to stop the operation of the batter feeding device, for example, when the molds and cores are being heated up at the beginning of operations. For this purpose I provide the spring-pressed pin 68 slidable through the support 52. The pointed end of this pin, when projected toward the-batter-feeding device, is adapted to engage the forward side of any dog 61 which is in position to be engaged by a projection =47of the lock of a properly locked mold and to push back the dog out of the path of the projection, (see Fig. 6). The stem of the pin has a cross pin 69 passed through it which may be engaged with the end of the tube 70 through which the pin 68 passes to hold the pin back against the pressure of the spring and therefore out of operative position. The tube 70 is cut away at 71 to permit of the pin 68 being projected when the cross pin is brought into alinement with such cut out portions. An operating handle 7:2 is preferably connected to the pin 68.
