This invention relates to a machine for making ice cream cones, and has for its principal object an improvement in the means for releasing baked cones.

A further object of the present inventionlies in the provision of means for opening the mold sections and closing them again after the cores have left the mold sections, but before the cones have reached the discharge position.

Further objects of t ie invention lie in t-he specific details of construction and are particularly pointed out in the claims.

In the drawings:

Figure Figure 1.

In Figure 1, the cone baking machine is of the present well known and generally used type, including a large wheel which supports all of the mold sections between the inner ring 10 of plates and the outer ring 11 of plates, these plates being bolted together and to the channel arms 12, which extend radially from the main wheel in accordance with established practice. y

The molds are each of two half sections 111 freely slidable in guides 15 on the two rings, and the half mold sections are pushed together to complete the mold and are withdrawn one from the other to separate the -molds by means of the crank arms 16, which extend through the plates of the rings 10 and 11 and carry on their outer ends the regulation cranks 17, each connected by a link 18 to a stud carrier 19 movable vertically up and down between a pair of guides 2O secured to each plate of the outer ring 11.

The two links 18 with the stud of the car- 7 is a cross section on line 7--7 of rier 19 form a toggle, which is opened and closed by a track (not shown), this track raising the roller 21 on the carrier 19 to open the molds and bearing down on the roller 21 to close the molds, the closing of the molds being accomplished through a direct pressure of the arm 16 on the half mold sections 14: While the opening of the molds is accomplished through a small rod 24 fast to the arms 16 and engaging a pair of relatively small bars 25 secured to the top and bottom extended edges of the half mold sections.

The cores 30, the same in number as the pockets of the mold sections, preferably six, are carried on a core bar 31 bolted to the top of the core carrier 32, each at its lower end having the customary roller (not shown) operating on a standard core operating track. I prefer to provide a second roller for operating the cores and mount this roller 36 on the free end of the core bar 31, and allow it to travel on a trackway 37 adjacent the periphery of the wheel as formed by the plates 11. All of the structure so far described is old and has been been covered in prior ap plications and patents, and no claim, there fore, is made to it in this application save in combination with the elements about to be described.

llVhen using a greater percentage of sugar in the making of the cones than has been used in the past, the cones are found to stick to the molds, and 1 ind that VV@by slightly opening and closing the molds after the cores have been Withdrawn, I have relieved the stickiness to a very considerable extent, and in many cases, have eliminated by this simple means the dificulty. 1 accomplish this desired result by a very simple means, namely, by the placing in the path of the roller 21 a cam to elevate the roller 1 and carrier 19 a small portion of the distance required to open the mold sections. rThis cam is preferably in the shape of a small block 1() secured to a permanent and non-movable part of the machine and sloping as at 4:1 to engage the roller 21 when it is in its down or mold-closing position.

The roller 21 rides upwardly on this slope 4-1 and remains open for the distance of: the

fiat portion 42 of the cam 40 and upon reaching the downwardly sloping edge 44, the mold will normally close by gravity.

In all machines upon which this device has been placed, the molds will close of' their own accord, largely due to gravity, and somewhat due to the jarring of the machine, these machinos normally being` of .intermittent type with a.l dwell between each of the positions usually in excess of 30. ln order to insure closing of the mold, however, I may place a small auxiliary cam 45 in the path of the roller 2l in case it is not lowered to full closing position.

In the ordinary sequence of the baking operation including the devices ust described the molds after discharge. of the baked product remain open for one period or position, and inthis position, a safety-first ejector' passes betweenv the open molds, and insuresthat no portion of Ia baked cone remains betweenV the mold sections. At the next position, the molds close, and alter closing, a small` amount of batter is deposited in eachv onezot the-mold cavities and at the next stage orhposition, theA cores 30 are lowered into the closed molds and the baking operation proceeds through the'next 25 or 30 positions, orjust solong as to give a perfectly brown andv thoroughly baked cone.. This brings the cones to the position just to the right of the portion of the machine shown in Figure'l, and in the first positionshown, which position ,is'number 30, the molds are slightlyopen, and inl the'next position 31,' the molds are closed, which brings us to the final. position,. whichA as illustratedV is the thirty-,second position. When the machine first arrives at this final position, the molds are closed with the baked cones in thecavities, but these cones have already beeirlooscned 'romono or both sides of the molfL in position above this stage 32, and when the comes to rest in this position, this ai'ixiliary` core "ar is raised, but-is immediately lowered into the baked cones by meansot a piston in. cylinder 5l. This pistonhas a rod 52 carrying a roller at the top andengages a shelf 53V on a sleeve 54 secured to a vertical shaft 5G, the cylinder 5l being` mounted on a stationary part ot the frame.

The auxiliary core arm 50 is provided with anV air chamber 58 in communication by a pipe 59lwith an air-pump, causing alternate pressure and suction in the air chamber 58, which communicates with the center cavity ot each ofthe baked cones, and when the auxiliary bar 50 is in its lowered position, it rests against-the smooth plane top ot' the mold sections and presses against the excess batter which joins together the six cones of each set or series. The preferred form oit-'this auxiliary bar is preferably in the form shown l v oy the opening of the mold sections at position in Figure 2, the bar being rectangular in cross section anc. carrying a plurality of circular plates 60, each having an annular peripheral flange 6l rising slightly above a circular plate 62 carrying a number ot perforations 63 communicating with the central orifice G4 of the auxiliary bar and leading to the air-chamber 58. The disks GO are secured to the auxiliary bars 50 by any preferred means, preferably by simple screws 66,- l prefer that the circular ring or flange 6l bound by these'disks shall be ot just sufficient size to engage snugly the waste immediately at the edge of the cone proper. ln other words, l prefer that these circular ridges shall just lree the cone itself.

ln the modified form shown in Figures-3 and 4, the auxiliary bar is slightlychanged.r ln Figure 8, the bar is plane throughout its extent, save for the slight marginal flange 70, which forms a frame for the main` portion. ln this modification, the air-chamber is that portion ot the-bar bounded by the continuous flange 70, antl this flange is of suflicient si-Ze to receive snugly the six baked cones and just free the slight rim at the top, engaging the waste only. ln Figure 4, the bar is again modified, this time by providingy a very largev surface to engage the waste `and by counterboring the bar itself to provide a` recess to receive the top edge ot the cone. ln'this modification, the air chamber is the space 74 within the counterbore. Here, again, the auxil` iary bar does not at any time `touch the baked cones, engaging solely the waste just surrounding the top edges of the six cones` As previously stated,'on reachingthethirty-second position, the molds are closed. The bar'O then'de'scendsand seats itself, no matter which modification is used, firmly on the waste, and it presses the waste against the top of the molds. rhe molds now by means or" well known mechanism start to open. The baked cones are prevented from following either mold section by means-of the pressure exerted by the auxiliary bar 50, the friction ot' this bar against the top of the mold being always considerably in excess-ot any-possible friction between the conc and mold. At this time, that is justbetore-the molds open, air' is withdrawn from the chamber 58 through the pipe 59, and this causes the six cones toget-her with their integral waste usually ormed'altogether in a-single piece to stick to the auxiliary bar 5041 as it rises by movement of the piston in cylinder 5l. This cylinder-5l "is fixed', and upward movement or ythe rod 52 causes upward movement of the shaft 50 and the sleeve 54, which moves upwardly with it, but whichv is formed to move angularly about the shaft. reaches its uppermost position, it is. oscillated by means of a piston within the cylinder 77, movement 'being imparted through Va piston rod 78 having its free end pivotally con- Vhen the sleeve 54' nected as at 79 to the shelf 53. The piston 77 is secured to the shaft 56 and has no movement except in connection therewith, so that movement of the piston within the cylinder 77 will cause movement through an angle of approximately 90 of the sleeve 54:. This sleeve carries a shaft 80 on which the auxiliary bar is mounted, and on which it is free to turn through an angle of 3600 except as limited by other mechanism.

The auxiliary bar 50 carries an upstanding lug 90 which engages the curved ca'm surface 91 on a bracket 92 loosely receiving the shaft 56 and secured to a stationary part of the mechanism. As the sleeve 54 is rotated, the lug 90 engages the cam 91 and throws the auxiliary bar 50 through an angle of 90o, changing the axes of the thereby'carried cones from vertical to horizontal, and

- swinging the baked cones with their Waste into the path of a series of brushes 9G carried on a shaft 9i' receiving motion through the belt 98. rIhese brushes remove all the waste from the cones, and at this time, the suction caused in the air chamber o8 is changed, by mechanism timed with the molds, to pressure, and this pressure forces the six cones through the brushes and on to the receiving table iOO, preferably having channels such as lOl to receive one each of the cones of each series thereby stacking the cones in position to facilitate their removal to the packaging machine. 'Ihe auxiliary bar 50 byr reverse movement of the piston in the cylinder 77 is now restored to radial position about the molds, and by gravity is restored to vertical position as soon as the lug 90 is freed from the cam surface 91 and the parts remain in this position until the large wheel again comes to rest in position 32, whereupon the first movement is the lowering of the auxiliary bar 50, and with it the sleeve 54 and the cylinder 77, both of these always moving with the shaft 56.
