This invention relates to means for making jelly rolls or the likefor use particularly in commercial bakeries, andthe present invention aims to provide an improved and simplified machine for this D 'D N- The well known bakery product commonly called a jelly roll may consist of a quantity of batter which is first formed as a flat baked slab of, say, sponge cake, upon the upper surface of which is spread a coating of fruit Jelly or the like, the slab being then; rolled u-p, with the jelly coated surface innermost, to form a roll, the coils of the roll advantag'eously showingat the ends of the roll to display the jelly content.

Among other objects, the present invention aims to provide mechanical means for the production of such-jelly rolls with a minimum. of manual handling, while at the same time insuring a more uniform disposition of the jelly upon the cake preliminary to rolling-up, and the production of a more uniform coil or roll in the final product.

These and other objectsij will be more fully pointed out in the following description, taken together with the accompanying drawings. of an illustrative embodiment of the invention, and in which drawings:

Figure 1 is a side elevational view of a machine constructed in accordance with the present invention, being somewhat schematic and with parts broken away for clearness of description;

Figure 2 is a fragmentary elevational view, similar to Figure 1 but showing analternative position of a part;

Figure 3 is a plan view of the structure of Ffgure 1; and

Figure 4 is a fragmentary plan view showing a portion, greatly enlarged. of a part of the machine.

Referring in detail to the illustrative construction shown in the drawings, a support is provided in the form of a mobile table II! comprising side frames I l and legs l2 which may be reinforced by longitudinal girders I3, wheels ll at the lower terminations of the legs serving asmobilizing means.

The two parallel main frameparts ll running longitudinally of the table serve as supports for a table surface or platform l5 forfthe upper runs of a plurality of longitudinally. aligned conveyors such as, in this instance, the endless belt canvas conveyors IE, IT and I8. The conveyor belts are entrained on the usual conveyor windlasses of which there may be a pair 19, and 20 for the belt i6 carried by axles 2| and 22 respectively, a pair 23 and 24 for the belt i1 carried by axles 35 and 28 z respectively, anda pair 21 and 28 for the belt it? carried by

axles

29 and 30 respectively. The axles may be suitably journaled in the side frames ll as indicated in the drawings.

As shown and broadly claimed in my co-pending application S. N. 525,556, of Morris Cohen, Gerald A. Jorg'enson and George Hasty, filed March 8, 1944, for Coating and rolling apparatus and now Patent Number 2,402,874 dated June 25, 1946, the present machine desirably includes a coating or jelly applying device here indicated generally by the numeral 38 and which may include a hopper 32 suitably attached as'at 33 to one of the side frames ii and offset laterally therefrom. The hopper 32 afiordsa reservoir for a supply of jelly in the fluid state which travels by gravity through the pipe 36 to the pump 35, which is driven by an electric motor 35. The pump 35 and motor 36 may be carried by the girders I3 of the table below the conveyor belts. Rising from the pump 35 is a delivery pipe 3'! on the opposite side from the reservoir 32, that is. the side near the observer in Figure 1, which is bent to clear the side of the table and. is then turned horizontally across the conveyor belt as at 38 to bring its discharge end 39 over the longitudinal center line of the conveyor. At the discharge end 39 is suitably secured a transverse spreader nozzle 40 which may have a discharge slot 40a elongated longitudinally of the nozzle or transversely of the machine for emission of the jelly or other coating.

The pump 35 is adapted to force the fluid up through the delivery pipe 31 and to the spreader nozzle 40 under pressure except when the pipe 3! is closed by a valve mechanism ii located in the part 38 of the pipe and controlled in this instance by a solenoid device 42. When the valve mechanism 4| is closed to prevent discharge of the jelly through the discharge nozzle 40, an overflow pipe 43 is provided communicating with the pump 35 at its lower end and having its upper end 44 bent over and turned down into the hopper 32. A relief valve mechanism d5 is associated with the pump 35 and overflow pipe 43 which opens to permit passage of the fluid from the pump to the overflow pipe when the pressure of the fluid in the pipe 31 by closing of the valve mechanism 4| reaches a predetermined point, the latter being adjustable by a hand control-screw d5.

In accordance with the present invention, means are provided for propelling the conveyor belts I6, I I and It at successively faster speeds and, as here shown, by an electric motor d1 3 mounted on the girders II at the opposite end of the table from the motor 86. On the output shaft 48 of the motor 41 are fixed a pair of sprocket wheels 49 and 50 which are of equal diameter. The sprocket wheel 48 has entrained thereon an endless driving chain 5| which is also entrained on a sprocket 52 which is fixed on the axle 28 of the conveyor belt II. This axle 28 also carries another sprocket 53 which is smaller than the sprocket 52 and which has entrained thereon the driving chain 54 which is also entrained with a sprocket 55 on the axle 22 of the conveyor belt 98, the sprocket 55 being the same size as sprocket 52. The sprocket 58 on the motor output shaft 68 has entrained thereon an endless chain drive 58 which is also entrained on a sprocket 51 carried by the axle 38 of the conveyor belt l8, the sprocket 51 being the same size as the sprocket 58.

Thus operation of the motor 41 will simultaneously drive all :three of the conveyor belts i8, H and I8, in the direction of the arrow 5141, the motor output shaft 48 being arranged to rotate in the direction of the arrow 51b. In one preferred instance, the speed of the conveyor belt 55 may be twenty-four feet per minute. By providing the sprocket 49 with fifteen teeth, and the sprocket 52 with twenty teeth, and the sprocket 53 with fifteen teeth, and the sprocket 55 with twenty teeth, the conveyor belt l6 will thus run slower than the motor 41 and slower than the belt 11. By providing the sprocket 52 with twenty teeth, the conveyor belt I I will run proportionally faster than the belt l8 but slower than the output shaft 48. By providing the sprocket 51 with fifteen teeth, he same number as sprocket 58, the belt l8 will thus run at the same speed as the output motor shaft and proportionally faster than the belt I1.

The conveyor belts are adapted to carry thereon, in the direction of the arrow 51a, a serie of articles to be dealt with by the machine such as the slabs of cake 58 disposed initially in any suitable manner on the machine, at the lefthand end thereof in the flat and in contact or abutment one with the other as at 59.

It will be understood that the cake slabs are formed of cake batter which has been suitably prepared in the bakery and thereafter baked before being brought to the present apparatus to be prepared into so-called jelly rolls and the cake slabs are commonly say fifteen inches long, that is transversely of the machine, about twelve inches wide, that is longitudinally of the machine, and about five-eighths of an inch thick, and each slab as presently described is here adapted to make two J'elly rolls.

When the slabs 58 are travelling on the belt I'B, the motor 41 being in operation, electric wire leads being connected with the terminals 68 of the solenoid coil 8| and also connected into the circuit of the motor 41, as will be readily understood and need not be here further described, the solenoid coil is energized and the usual armature 82 of the solenoid device 42 is raised to open the valve of the valve mechanism 4|. Thus as the cake slabs 58 travel on the belt l8 under the transverse spreader nozzle 48, the jelly is discharged therethrough in a continuous film or sheet which is disposed by gravity onto the cake slabs thereunder.

Since, in accordance with the present invention, the cake slabs are in abutment, the jelly may be discharged continuously during operation of the machine. If, however, the motor 41 is shut down,

the solenoid coil 8| will be de-energized thus re leasing the armature 82 and allowing the valve of the valve mechanism to close under pressure of the fluid in the pipe 81, and so discontinuing discharge of the jelly through the nozzle 48.

With the machine in operation as described, the cake slabs, after being coated with jelly, pass from the conveyor belt l8 to the conveyor belt H where their speed is increased so as to begin to space the cake slabs apart, and they are further spaced apart as they pass onto the last conveyor belt I8. They are now spaced apart so as to be individually dealt with by the rolling-up means indicated generally by the numeral 68 which in this instance is shown in 'the form of a section of flexible chain belt 88a having one end suspended from a rod 84 which is rotatably mounted at its ends as at 85 in a pair of posts 86 upstanding from the table frames H respectively.

The chain belt section 8311 extends from the post in the direction of movement of the conveyor belt and tends to drag thereon as at 81 i Fig. 2), thus functioning somewhat as a loosely hung flexible apron. A fragmentary enlarged plan view of a portion of the chain apron 53a illustrating one illustrative formation thereof is shown in Figure 4, and in which the metal ribbons 68 are sinuously formed to be loosely interengaged by similar ribbons 68 flexibly joining the ribbons 88 and bent lockingly thereabout providinga device which is extremely flexible longitudinally of the machine but rigid transversely thereof, and which at the same time has sufficient weight to accomplish the purpose next described.

As shown in Figure 2, one of the cake slabs 58 which is here given the additional designating numeral 58a is show as moving on the belt l8 just at the point where its forward edge contacts the chain apron 6-3 and this forward edge is shown turned up as at 10. As the slab 58a continues to move forwardly carried by the belt under the apron 83a the dragging function of the latter on the cake slab continues to roll this up a shown at 58b (Fig. 1) at which stage the jelly roll is almost completely rolled up.

As the jelly roll 58b continues still further under the apron 63a, it passe freely under the free edge of the apron and by this time is completely rolled up, and then it becomes desirable to prevent it from uncoiling. For this latter purpose, the expedients next described are advantageously provided.

Suspended over the belt l8 beyond the rollingup means 63 is a setting device for the jelly rolls generally indicated by the numeral II and here shown in the form of a pressure plate 12 spanning the conveyor l8 and adjustably supported thereover as by a link mechanism comprising a pair of links 13 pivoted as at 14 on the side frames II respectively and articulated as at 15 with the pressure plate I2, another pair of links I6 similarly pivoted as at 11 on the frame intersecting the links 13 respectively at 18. A sub-link 19 is articulated as at 88 with each link 16 and as at 8| with the pressure plate. The connection 18 is both pivotally and slidably adjustable to permit raising or lowering of the pressure plate and the adjustment may be fixed by a hand screw 82. The edges of the pressure plate facing the ends of the machine are desirably upturned as at 83 and 84 to permit ready ingress and egress of the jelly rolls with respect thereto.

As the jelly roll, which may now have the designating numeral 580, passes under the influence of the pressure plate 12, the jelly roll is desirably rotated on its own axis as well as moved forward bodily by reason of the fact that the pressure plate is stationary while the jelly roll is moving thereunder and in contact therewith on the belt I8. This rotation, .which is fairly gentle, is

sufficient to set the jelly roll, that is, to give it surface of the pressure plate 12. In the'vicinity of the circular blade 88 and between the bearings for the blade spindle, the pressure plate is slotted as at 9| to permit the blade to turn therein and have its lower portion depend below the pressure plate centrally thereof into the path of the jelly rolls as at 92, and thereby severing each roll 580 into two similar cylinders or rolls 58d of one-half the length of the original roll.

Rotation of the jelly roll as previously described assists in causing the knife 85 to make a clean quick out, without the knife touching the conveyor belt.

These two jelly rolls 58d then pass out from under the influence of the pressure plate, carried by the conveyor belt to the end thereof as at 58c and are ready for the wrapping machine. As is well known, the coils or turns of the jelly roll are desirably visible, showing the jelly at the ends of the roll, to enhance its appetizing character.

The invention is of course not intended to be limited to details of structure shown for purposes of exemplification. Furthermore, it is not to be understood that all features of the invention must be used conjointly,'since various combinations or sub-combinations may at times be ad-- vantageously employed, embodying the invention in one or more of its aspects. Such changes or adaptations may be made as fall within the scope of the appended claims without departing from the invention.
