'AiPPARATUS FOR THE MANUFACTURE OF ICE-CREAM GONES.

T oaZZ whom it'may concern:

Be it known that I, LEWIS LEWISON, of the city of Hamilton, county of VVentworth, Province of Ontario, Canada,have invented certain new and useful Improvements in Apparatus for the Manufacture of Ice- Cream Cones, of which the following is a specification.

This invention relates to apparatus for forming and cooking conical food containers which are themselves edible and particularly to that type in which a series of radially arranged divided molds and cooperating cores are supported on a rotary carrier to which a stepwise movement is given to carry each mold in succession to a filling device, thence through heating devices to a discharging point, suitable means being provided-for actuating the feeding device, opening and closing the molds and moving the coresto and from their cooperating position with the molds as necessary in the cycle of operations.

, It is my object to devise apparatus of this type which will be rapid and certain,- and absolutely automatic in operation, and particularly to devise means for preventing the sticking of pieces of broken cones between.

the parts of a mold or breaking of a cone in a mold in any way damaging or interfering with the proper operation of the machine if not immediately detected and the trouble remedied. A

I attain my objects by means of the constructions hereinafter described and illustrated in the accompanying drawings in which- Figure 1 is a plan view of my improved indicate corresponding parts in the different machine, showing only a, portion of the molds and cores;

By this arrangement any over movement of the carrier due to momentum is absolutelv (shown particularly and through derneath by I relationship,

Each mold is formed of a pair of separable sections 13 connected to arms 14 provided at their ends with inter- 16 is a yokeengaging hinge knuckles 15, shaped bracket embracing the hinge knuckles in Fig. '5). 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 bracket, through the hinge: knuckles 15 the carrier, being secured unmeans of a nut and above the upper jaw'of the bracket by a pin .19.

he 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 1s hinged behind the hinge pin 18 on lugs 22. formed on the bracket 16. From this arrangement it follows that by the r'emovalof one screw and a nut, a mold and core unit is quickly and easily removed ,or replaced whenever necessary. At the same timethe arrangement of the yoke-shaped. bracket always maintains the parts connected therewith in proper. and the mold arms are as short as possible which tends to prevent them springing. With short and thereforerigid arm s, single locks at the free ends are sufli cient. Withv long ave in some which is 7 on the shaft 8. On

' in the molds,

anti-friction rollers the jaws of an objectionable complication and the formation us on the cones is To assist in the proper alinement 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 terbalancing springs 24, the other ends of which are secured to the arm 21.

The hinge pins 18 also serve to support the locking levers 25; Each locking lever is preferably forked to embrace the hinge pin to which it is pivoted at its upper end.

ne end of each locking lever is provided with a projection 26 preferably formed as a roller adapted to engage in a slight identation formed at the upper end of the arm 27 secured to the core arm. -.The other end is adapted for engagement" by locking or unlocking cams and is also preferably formed as a roller 28. It will be seen that when the locking lever is in the position-shown in Figs. 5 and 6 that thecores will'be locked but that owing" to a measure of resiliency in the hinge pin 18 and arm v27 a slight automatic lifting of the cores is one end of one or more countionary cam 31, preferably secured to the journal 3. TlllS cam is ada ted to engage over. projections 32, prefera lily formed as and secured to the heels of thecore arms 21 behind their hinges. The cam, as shown particularly in Figs. 21 and 22, is provided with an inclihe 33 adapted to slightly raise the core arm, followed by a dwell and terminating in a portion 34 adapted to depress an engaging projection and thereafter to allow it to rise. The friction on the cam is, of course, con siderably relieved by the action of the counterbalancing springs The mold sections are, normally pressed to the closed position by means of the bent springs 35 which are located between the molds, the springs being provided with outwardly bent ends 36 adapted to enter holes 37 in the adjacent sides of adjacent molds. To open the molds I provide for each mold a vertical spindle 38 journaled on the car rier. Each spindle is provided with projections 39 normally parallel to and received between the arms 14.

On the lower end of each spindle below the carrier is a projection 40, which, when the projection is in the position shown in Fig. 5, lies in the path of the cam 41, (see particularly Figs. 1, 3. and 4.) The arm 42 supporting this cam from the frame work of the machine is preferably somewhat resilient so that the cam will yield if any mold has through accident remained locked, as hereinafter described, at the time it should be opened by the engagement of the projection 40 of its operating spindle with the cam 41. e V

The mold sections must be firmly tightened together and locked closed during the filling of the molds and the cooking of the cones. It is also very desirable that the locks be so arranged that the mold sections are not forced together in the event of a broken cone or other obstruction remaining between the parts or otherwise the mold sections or closing mechanism might be broken. It is also very important that no batter shall be fed to a mold which has not been properly closed. To accomplish the desired results I provide the following mechanism. On one section of each mold is pivoted a 25 hook-shaped lock 43 which is adapted'to engage over a pin 44 on the co-operating moldsection. The hook is so shaped that it will normally tend to fall to the reliminary closing POSltlOIl. as shown in ig. 14, with a slight shoulder 73 resting against the pin 44, requiring the application of force to press the lock to the final closing position and jam the sections 'closel together.- This force is applied through t e medium of a stationary chine in such .a position .that, as the mold travels toward it, will engage, according to circumstances,either-below or above the center of a projection 46 on the lock, formed as an anti-friction roller. If the lock has fallen to the preliminary locking position, as it will if there are no obstruc-- tions 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 locking position, as shown in ,Fig. 19, in which case the cam 45 "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. I

The locks 43 are. also usedto actuate the batter-feeding device, ing formed for that purpose.

is properly locked, this pro the position shown pa W hen a :mold ection occupies 15, and 16, in which position it will engage and operate the batter-feeding device. If

cam 45 supported from the frame of the mapreferably the projection '47 berticularly in Figs. 5, 6,.

Figs. 12 and 19, in which it will not operate the batter-feeding device as will hereafter appear.

he batter-feeding device comprises a. cylindrical casing 48 and the cylindrical battermeasurin device and valve 49 rotatable therein. he casing is provided with a flange 50 at each side adapted to be inserted in the grooved guides 51 formed at the lower end .of the inwardly and downwardly projecting arms 52 extending from the support 53 formed on or secured to the frame of the machine. From the support 53 extends the rod 66. With the free end of this rod the valve '49engages when the batter-measuring device is in the position shown in Fig. 33, the .valve being thus held securely in position when the casing is positioned on the, guides 51. A set screw 54 is preferably provided for clampin one of the flanges 50 in its grooved gui e. K

From this arrangement it follows that the batter-feeding device is readily placed in position or removed from the machine and disassembled in a few moments for cleaning purposes. 1

The casing communicates by means of suitable feed openings with the ho per 55, which hopper is closed and provided with a pipe 56 which may be connected with any suitable source of batter supply.

As a plurality of mold recesses are employed in each mold, a plurality of inlet openings 57 are employed in the top of the valve casing communicating with the hopper and a plurality of discharge openings 58 are provided in the bottom of the casing.

The valve 49 is provided with a plurality of radial pockets 59 arranged in sets, the sets corresponding in number with the number of mold recesses in each mold. Each radial pocket has an opening 60 through the periphery of the valve of lesswidth than the width of the pocket (see particularly Figs. 28, 29, 30,31- and 32) which causes a proper 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 relatively long compared tothe periods of movement, ample time is rovidedfor proper fillingand complete draining of the radial pockets.

The end of the valve has a plurality of dogs 61, corresponding in number to the radial pockets, ment of each dog in'the direction of rotation is, however, limited by the stops 62. When a mold approaches the batter-feeding device, (see Figs. 15 and 16), the projection 47 and its lock, assuming the mold to be properly locked, will engage one of the dogs 61, press of rest, which are a batter effectively than if the .will help to .By this time the projection 46 has 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 isin position to discharge through the discharge openings of the casing: If the mold is not properly locked, passes by without engaging the proper dog to rotate the valve and no batter is fed,(see Fig. 19). It will be noted particularly on reference to Fig. 6 that each mold section is formed with the lip 73' extending upwardly from its face at the outer side thereof adjacent the. mold recesses.- These lips serve to prevent batter spreading out over the sides of the mold and thus forming laterally proecting fins which would prevent the cones molds as they open. 21 above the molds are prowith the laterally extending lips 74 serve to prevent the burning of any forced up between the core arms and the lips 7 3'.

While the operation of the parts will be readily understood from the foregoing description taken with the drawings, a general outline of the mode of operation setting forth the coordination of. the parts a better understanding of the invention.

Assuming a mold to be closed and locked, it is traveling between upper and lower as jets 63 and 64 arranged andsupplied with a combustible mixture in any well known manner. On arriving near the position for the discharge of the baked cones, the locking lever 25 engages and is rocked by the cam 30 this engagement, however, takes place slightly after the projection 32 has engaged the incline 33 of the cam 31. The result .is that the core springs up sharply, releasing itself from the baked cones more movement were more gradual. The incline 33 frees the core from the cones in the mold, mold sections are unlocked by the engagement of the projections 46 with the stationary cam 67 opened up sharply by the rocking of the spindle 38 through the engagement of the projections 40 with the cam 41. cones will be held in approximately central position by the slightly disengaged cores, "th

the mold sections readily pull away from the finished cones so'that sticking of the cone to one side or the other is'p'revented. The

cones now drop and the core rises up to the the 41 and the molds are closed by the springs 35. assed the cam 67 andthe lock 43 is free to 7 all to the projection and at this point the The sections are now.

As the the side by the bent spring 65,- which has a curved hump formed at its end. This spring, when the hump engages the projection 32, presses the, core firmly to. the closed position so that the end of the core arm 27 is in a position to be engaged by the projection 26 as the locking lever 25 is moved toward the locking position by itsengagement with the cam 29. If there is any obstruction in the mold, the spring yields and the core is not pressed down and is not locked. After passing the hump on the bent spring, the projection 32 does not engage the spring so that the action of the latter on a projection just passing from the stationary cam 31 is not interfered with. Each mold in turn the series ofoperations just described as long as everything is I, going well. If, however, any mold becomes obstructed, the safety devices, hereinbefore described come into operation and the machine makesno attempt to close the obstructed mold and no passes through batter is fed thereto. If one of the pro-;

jections 46 becomes brokenafter a mold is locked so that its hook 43 does not automatically unlock, still no harm is done to the unlocking device as the cam 41'yields to allow the projection 40 of the mold-opening device to pa by. 1

It is desirable at times to be able to stop the operation of the batter feeding device, for example, being heated up at the beginning of operations. For this purpose I provide the spring-pressed pin 68 slidable through the .support 53. 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 aprojection 47 of the lock of a. properly locked mold and to push back e dog out of the path of'the :"projecti'on, (see Fig. 33). 'The stem of the in has a cross pin 69 passed through it w ich may be engaged with the end of the tube ,70 through which the pin 68 passes to hold the pin back a .ainst the pressureof the spring and there ore out of operative .BThe tube 70 is cut away at 71 to permit of pin 68 being projected when the cross V pin is brought into allnement with such cut out portions. preferablyconnected 'to the pin 68.
