JACOB 5. Fume BY 41W lation to the cross bars l2, l3.

the shaft 40 is a Sprocket wheel 44 driven by a downwardly extending drive chain 45 trained at its lower end about a sprocket 46 mounted adjacent its other end on the upright 2. trackway 56 is contoured to form a vertically .inverted cone-molds 33, each of which is co-axial with a mandrel 23. Each of said cone-molds 33 has a slot 34 therein at its outer side and extending from the rim down to the apex. It is essential that the slot extend a distance at least sumcient to accommodate the diameter of the generally circular wafers designated w which are to be rolled, as hereinafter referred to. It is also necessary that the slot extend to the cone apex, so that the rolled cones designated may be formed with completed tips. Each cone further has a so-called loading flange 35 forming one side of the slot 34. Said flange 35 projects outwardly beyond the periphery of the plate 3| and has mounted at its outer edge, by rivets, a scraper blade 36, the outer face of which is flush with the adjacent surface of the flange 35.

Afilxed, as by welding, at their upper ends to the under portion of each slide bearing 2| in the plate 22, and spaced from the associated spindle 28, is a pair of opposed generally concave stripper arms 31, the lower end of which are adapted for frictional engagement with the outer surface of the related mandrel 23 for stripping rolled cones therefrom, as will be presently described in detail.

Secured to, and depending from, the under face of the mold-support plate 3| is a circular rack 38 designed to mesh with and be driven by a gear 39, keyed or otherwise mounted upon a relatively short shaft 40 journaled in bearings 4|, 42, supported on cross pieces 43, 43', respectively, secured at their ends to the horizontal sections l4, l5, adjacent the upright 2 and in parallel re- Engaged upon adjacent the rearward end of a forwardly extending shaft 41 journaled in brackets 48, 49, respectively, secured to the upright 2 and a post member 50 presented adjacent the forward margin of the base plate 5. Mounted on the forward end of the shaft 41 is a sprocket 5| driven by a motor 55.

It will thus be seen that upon actuation of I the motor 55 rotation will be imparted to the vertical shaft 9 through the gear 39 and the rack 38 thereby causing the plates I6, 22, and

3| to rotate in a counterclockwise manner and thus causing the cone molds 33 and their associated spindles 20 to move in a circular path.

Referring to Figures 1, 2, and 17, it will be seen that secured at one of its ends to the upright 4 is a cam or trackway 56 for co-operation with the follower rolls 29. Said trackway 56 progresses rearwardly along an are substantially concentric with the plates I6, 22, 3|, being of slightly greater radius and suitably supported Said curved path with the highest point thereof being disposed just inwardly of the upright 2 with gentle downward inclinations on either side. Thus, upon rotation of the plates I6, 22, 3|, the cam followers will encounter the trackway 56 after having passed the forward portion of the machine A and ride therealong with consequent upward sliding movement of the spindles 20 within the bearings I9, 2|. The free sliding of the arm 28 upon the rods 3!! permits smooth, relia ble up and down movement of the spindles 28. Thus, with each revolution of the shaft 9, each mandrel 23 will be upwardly removed from its normal disposition within its associated mold 33 and be returned thereto. Referring to Figure 14, it will be seen that when a follower roll 29 has reached the peak of the trackway 56 the spindle 20 will have been raised sufficiently for the stripper arms 31 to come into contact with the outer face of the mandrels 23 for exerting pressure upon the upper margin of a cone 0 rolled thereon to strip same from adherence to the mandrel 23. Thereupon the cone C will drop downwardly into an inclined chute 51 suitably supported by means exterior to the machine A for conducting the cone C to a collector (not shown).

Aligned laterally, at the forward part of the machine A with the post 50 is a companion post member 58, said

posts

50, 56, being interconnected at their upper ends by a horizontal bar 59 to the forward face of which is secured an auxiliary motor 68, having its drive shaft 6| vertically disposed with a double grooved pulley 62 engaged thereon. Supported upon the pulley 62 is a pair of

drive belts

63, 64, which extend about horizontally spaced

sheaves

65, 66, mounted for rotation upon

stubs shafts

61, 68, respectively, disposed in laterally and rearwardly projecting

arms

69, 10, respectively, rigidly fixed to the rearwardly presented faces of the

posts

50, 58, respectively. The

drive belts

63, 64, thus traverse a triangular path with the rearward leg thereof presented for frictional engagement with the drums 25 on the spindles 20 to impart rotation thereto. Upon actuation of the motor 60, which may preferably be connected to the same main switch as the motor 55, the spindles 20 will be caused to rotate while moving through that are of their travel confronted by the

drive belts

63, 64. Thus, for a predetermined period of time, the cone-rolling mandrels 23 will be actuated for cone-rolling operation through a defined portion of their total travel.

The means for conveying the wafer or cake to the machine A for cone-rolling purposes comprises sub-framing, which includes a relatively short vertical upright 1| laterally aligned with the upright 3, being forwardly and to the left, reference being had to the left hand side of Figure 2, of the upright 4 to which it is connected by a cross bar 12. Aligned forwardly with the upright 3 is a short post member 13 in lateral alignment with the

posts

50, 58. Secured fixedly to the uprights 3, 1|, and the

posts

50, 58, 13, is a pair of vertically aligned, horizontally extending channel members, generally denoted 14, for forming upper and lower railways 15, 15', respectively, which extend at one end past the upright 3 and post 13 into a baking oven, generally designated 16, and at their other end terminate slightly beyond the upright 1|, at which end the upper and lower railways 15, 15', are connected by a pair of

sprocket wheels

11, 11, each being associated with one vertically aligned pair of channel In-embers may. "seen; in

Figures land 3; the rai1ways"15', 15",are in'downward relation to" the forward fp ortion of thecir- 'cu'larplate 3I. ""'Said sprocket wheels'l'l 11", are

projecting portions'of the flanges '85, 85', are outwar'dly offset] as "at '88 for alignment with the "projectingportion of the flanges of the adjacent :plateYBA for registration of suitable apertures therein through which freely extends a hinge pin 8], On the" opposite projecting ends of each hinge pint? there isfmounted a roller 88 for movementialong the railways 15, I. Each of said rollerstii is'integrally provided with a diametrally enlarged flange 89 for disposition intermediatethe inwardly presented faces of the trackways, I5, and the adjacent projecting iflang'es 85,15, of the plates 84' to maintain said plates 84 in alignment and, prevent untoward 'displacement of theconveyor B u'ponfth'e

"Bolted 'to the'upper' face of eachof the plate sameness" is the bottom' plate 90 of a griddle member 9! having a cover or top plate 92 adapted Q forfiatwis'e closure disposition upon the bottom plate 99'and being hingedly secured thereto for upward and forward opening" swinging movement.

Integrally formed withlthe cover plate 92 and on the no muy rearwardly pres ented edge thereof is a projecting lug v9 1. For camming'engagement with the lug 95 of each griddle member BI is a guideway 95 comprising a pair ofrod-

The operation of the machine" A- is -as'followsz The motor 55 is actuated to cause theplates l fi, 22, 3|, to rotate in a counter-clockwise manner, as stated above, and toeffect movement of the V conveyor B for continuous progression about the railways 15, 15', moving outwardly-omitsflower traverse from the oven 16 and. being brought in a.

upon the rod-like member 91 for continin, as the griddles 9| retain substantial quantities of heat absorbed during the movement through the oven 16. As the griddles 9| approach the sprockets I1, 11', the lug 94 will follow the rodlike member 91 and thus be led forwardly by the guideway 95 which, by its upwardly extending path, causes the top plate 92 to be raised from the lower plate 90, thereby opening the griddles 9|, with maximum opening attained along that portion of the guideway 95 which is immediately adjacent the

posts

50, 58, as may be seen in Figure 3. The wafer w will adhere to the grid 93' of the top plate 92 since the same is coarser than the lower grid 93 and, hence, tends to become embedded within the wafer w. Referring to Figure 3, it will be seen that when the top plate 92 is in maximum open position the lug 94 will abut on its normally upper surface against the plate which effects a pressure thereon to prevent untoward swinging movement of the plate 92 as the scraper 36 of a cone mold 33 comes into contact with the grid 93' for lifting the wafer w therefrom and causing same to move along the loading flange 35 and into the main cavity of the mold 33 (see Figures 9, 10, and 11). Thus, any outwardly directed thrust exerted upon the plate 92 of the griddle 9| by the cone mold 33 during wafer removing action will be positively countered by the force exerted by the plate |0| to assure clean and complete transference of the wafer w to the cone mold 33. Within the mold 33 the wafer w will become wound about the revolving mandrel 23 associated with the particular mold 33 for rolling same into cone formation, the ridges 24 tending to protrude slightly into the wafer w for maintaining same securely upon the mandrel 23. Rotation of the said mandrel 23 within the mold 33 is produced through coaction of the drum 25 upon its spindle 20 and the

belts

63, 64, associated with the now actuated motor 60. As the spindle 23, upon which the particular mandrel 23 now being described is mounted, is moved beyond the sheave 66, engagement will be lost between the drum 25 and the belts 63, B4, whereupon revolution of the mandrel 23 will be terminated. Thus, the cone C rolled upon the mandrel 23 is permitted to set until discharged into the chute 51 by the stripper arms 31 when the associated follower roll 29 has reached the highest point of the trackway 56, described hereinabove. Thereafter the mandrel 23 will be continued in its counter-clockwise path for ultimate repetition of the cyclical operation.

The particular timing requisite in the operation of the machine A is to be noted in that the shaft 9 must be rotated at such a speed with relation to the rate of travel of the conveyor B to assure proper coincidence of a cone mold 33 and the fully opened top plate 92 of a griddle 9| at a Y point immediately adjacent the plate |0| for effective removal of the wafer 11:. Simultaneous with this meeting of the mold 33 and the top plate 92 the spindle 20 of the mandrel 23 associated with the said mold 33 must be rotatin at Subsequent to the wafer scraping operation the griddles 9| continue along'the upper traverse of the conveyor B with the lug 94 riding now downwardly along the guideway 95 into progressively closing relationship with the lower plate 90. Just prior to the complete closing of the griddle 9| there will be discharged upon the lower plate a pre-measured quantity of batter sufflcient to form a wafer w. Immediately thereafter the griddle 9| will be completely closed and remain so through gravity as it is moved into and through the oven 16 where the baking of the wafer w is initiated. As stated hereinabove, the absorption of heat by the griddles 9| permits the baking of the wafer w to be continued while the conveyor B moves along its lower traverse so that minimum time is passed in the oven I5 and the wafers w are presented in a fully baked, warm, pliable condition for removal by the scrapers 33.

Previous attempts at mechanical transference of wafers from grids into cone molds have uniformly failed. While not heretofore known, the cause of failure included inadequate contact and travel as between scrapers and grids, and slowness in transferring the wafer as well as in the rolling operation. To overcome the problem of slowness, the machine A rotates the mandrel 23 so fast that, upon being first contacted by the edges of the wafers w being removed, they seize and lift them from the top grid plates 92, as shown in Figure 10. To permit the wafers w to be so lifted and drawn into the molds 23 without interference from the edges of the slots 34, opposite the loading flanges 35, the width of the slots 34 is increased as the diameter of the cone cross section increases, thus providing the necessary clearance. The spinning is completed before the wafers have cooled or lost their adherency. To assure adequate contact and relative travel between the scrapers and grids, the center of rotation of the spindles 29 is about a vertical axis in perpendicular relation to the upper path of the conveyor B so that, at the moment of scraping of each wafer w from its top plate 92, the said plate 92 is following a course tangential to that of the cone mold 33 and in a direction directly opposite. The thrust exerted by the plate |0| assures full contact during the travel of a cone mold 33 through an are which, though small, assures the positive removal of the wafers from the grids.

It is to be further noted that the machine A requires no manual operations whatever. In contrast, other currently used cone rolling machines require operators to deliver batter to the grids and, more seriously, to remove the hot baked wafers from the grids and feed them manually into cone-forming molds. If they are permitted to cool, the cones will not adhere. Handling such hot wafers results in burns to the operators hands; it is not possible for a person to do this work continuously for more than an hour or so at a time. Further, such operators must be experienced and skilled at feeding the wafers into the molds. But with the machine above described, the operation is entirely automatic.

It should be understood that changes and modifications in the form, construction, arrangement, and combinations of the several parts of the ice cream cone rolling machine may be made and substituted for those herein shown and described without departing from the nature and principle of the present invention.
