Application filed Eovemhcr 10, 1924:. Serial No. 74=8,331.

This invention relates to improvements in confection coating machines and, more particularly, to that type of machine where in the confections are carried through a casing by a conveyor and coated by traveling through a stream of coating material.

In machinesof this general type, various working parts become covered with the coating material, usually chocolate, and are hard to clean. It is diflicult to keep the machine in that clean, sanitary condition which is to be desired, considering that the products 01'' the machine are intended for human consumption. While the machines can be, and should be frequently cleaned, they are so constructed. that the cleaning operation is rather hard to perform and accordingly, it is often neglected.

This invention is concerned with, and has for its general object, the provision of a confection coating machine, wherein all oi the essential working parts, which are subjected to the coating, can be quickly and conveniently removed from the casing, and easily cleaned as separate units under the most favorable conditions, leaving thecasing entirely free of the usual obstructions so t rat an operator can easily enter the casing and clean the same and other stationary parts aflixed thereto. a

While certain of the working parts of a confection coating machine, such as the chocolate supply tank and the screw elevating means therefor, have heretofore been made removable, I wish to point out that the problem is only partially solved thereby. The supply tank and the screw elevator may, it is true, he as readily cleaned as with the present invention, but their reinovability does not contribute to the desired result of facilitating the cleaning of the machine, as a whole. The chief diiiiculty with prior machines has been that the pervious conveyer, or so called wire belt, together with its various supports and driving and guiding rolls, has not been removable and these elements, in effect, partition the cars ing into two parts, each of which is too small to allow convenient access to the interior of the casing for the cleaning operation. Tee removal of the wire belt, and its associated elements, is, therefore, the keynote to the successful accomplishment of the de sired abject because the principal obstruo .tion to free access into the casing is removed and also because the belt and its associated elements are exceedingly diiiicult to properly clean while held in place in the machine.

Other objects and advantages will appear in the following description and in the illustrative embodiment of the invention, in the accompanying drawings, in which Fig. 1 is a small scale front elevational view with parts broken away, of a confection coating machine en'ibodying the in vent-ion;

Fig. 10 is a fragmentary cross-sectional view taken on the line 10-10 of Fig. 3.

Referring to these drawings and particularly to Fig. 1; the machine, in its fundamentals, is similar to that disclosed in U. S. Letters Patent No. 735,890, granted August 11, 1903, on an invention of E. P. F. Magniez. lit includes a suitably heated casing A, through which the confections to be coated are carried by a perviious conveyor 7), usually oi wire mesh construction. Confections are supplied to the wire belt Z) by a feed belt 0 and the coated confections are transferred from belt I) to a delivery belt (5. The coating material is contained within a main supply tank 6, housed within casing A below belt b and mounted on a wheeled truck f, whereby it may be rolled into or out of easing A through a door A, after the general manner disclosed in said patent. Coating from tank 6 is carried upwardly through a tube 9 (Fig. 2) by an elevating screw it and delivered by Way of a spout i into a shower pan j, from which it i sues torough 5 (Fig. 1) in a downwardly directed stream upon the confections carried by beltb. A pair of rolls Z, mounted directly below belt I), pick up some of the coating passing theretln'ough and ap ply it to the bottoms of the confections in the usual manner. The confections, thus coated, are carried by belt I) in under a fan m, from which a downwardly directed blast of air issues upon the confections to remove superfluous coating. Any wrinkles in the coating, due to the action of the fan, are smoothed out by vibrating belt I) in the usual manner by meanslater to be described.

The wire belt I) is of usual and well known construction and travels, in its upper stretch, horizontally from one end of easing A to and beyond the other end and into an extension. This extension comprises side frames 72 and inner and outer hotom walls 0 and 0 (Figs. 4- and 5). The frames n are connected to casing A at one end. and supported at the other end by legs p. At the ends of the upper stretch of belt I) are very small rolls 9 and 1' and the lower stretch is guided around rolls 8 and t, the former being a tension roll and the latter the driving roll. Intermediate the rolls Q and 7', are grid like frames at, 'v and 10 which function to support belt Z) in its upper stretch of travel and may also act to vibrate it, as and if desired. As shown, frames a and w are vibrated while frame uis not.

The frames a, o and w are each of similar construction and a description of one will suffice for all. These frames are best shown in Figs. 3, 4 and 10 and each comprises two laterally spaced side bars 15 connected together by two cross bars 16 to which are fixed in laterally spaced relation a plurality of longitudinal bars 17 set on edge. The upper faces of the bars 15 and 17 are arranged to contactwith belt 6. Each side bar 15 is forked at one end to straddle a stud 18 mounted in the adjacent side frame a, where by each frame ispivotally supported at one end on a pair of these studs and may be lifted free therefrom and removed, when desired. The studs of each pair are shouldered, as shown in Fig. 8, to hold the frame from sidewise movement. The pivot studs 18 for frame w are fixed in fran'ies a but the other studs extend through and beyond the frames and have fixed on their outer ends ratchet wheels 19 and outside these wheels sprockets 20. The forward ends of the side bars 15 of frames 1) and w are offset outwardly and upwardly lo overlie the ratchet wheels 19 and carry vertically adjustable pawls 21, to co operate therewith. The forward ends of the sidebars of frame a, which is not vibrated, rest on shouldered down portions of the nearest bottom coating roll Z, as clearly shown in Figs. 3 and 4;. It will be seen that each of the frames a, o and 'w is conveniently removable,when the tension of belt 6 is relaxed by simply lifting them free of the ratchets 19 and studs 18. Thus, all the intermediate supports for belt I) are mounted for convenient and expeditious removal.

The various rolls which engage belt I), are likewise mounted for quick and convenient removal. These rolls are naturally arranged in two groups, one at each end of belt 6,

and, by preference, are removable from the machine in groups rather than individually, as by so doing the dismantling of the neces sary parts for cleaning is so much the more quickly performed. It is recognized, however, that the particular groups chosen may be subdivided and other groups formed and that rolls may even be removable individually. In the present case, rolls Z, q and 8 constitute one group and rolls 7 and t the other group.

Referring to Figs. 2, 3, 4; and 5, the rolls .7, g and s of the first named group are rotatably mounted at their ends in, and extend between, a pair of laterally spaced, parallel side frames arranged one adjacent each ide of easing A. Each frame 22 has an outwardly extending horizontally disposed flange 23 which rests upon a horizontally arranged angle iron fixed by brackets 25 to the side walls of easing A. A pair of longitudinally spaced pins 26 are fixed in upstanding relation on each angle iron 2% and each flange 23 fits between a pair of the pins 26 and is held from endwise movement thereby. One face of each frame 22 abuts the inner face of the angle irons 52st, whereby the frames are held from moving outwardly, and inward movement of the frames is prevented by the rolls therehctween, which are shouldered near their ends to abut the inner faces of the frames. It will be evident that frames 22, with the rolls Z, r, and a, may he removed as a unitby simply lifting them free of the angle irons 2d and pins 26. These frames, when removed, may be held from scparating'in any suitable manner and, as shown, may be held sufficiently by the gears 27 and 28, hired to opposite ends of one roll Z, outside frames The gear 28 drives by an idler gear 29 a gear 30 on the other roll Z. The rolls 1 and are not driven. Roll 1 is provided with the customary scraper 31 and roll is mounted for longitudinal adjustment and is forced to r ll) the left (as viewed in Fig. 4-.) by springs 32, which thus serve to tension belt 7).

Referring to Figs. 3, l and 5, the second group of rolls, comprising rolls r and z, are mounted at their ends in, and extend between, two spaced side frames 33, which are removably mounted at the outer ends of frames 17.. These frames are cut out in step fashion and the frames 33 are correspondingly formed to fit in the cut out portions. The are held in place by spring pressed pins 34; (see Fig. 9) which are slidably mounted in frames 33 and enter into holes in frames '11 to hold frames 33 against upward or sidewise displacement,-longitudi nal displacement being prevented by the tension of belt Z) which holds frames 83 snugly against frames n. The roll '1' has fixed to its rear end a pinion 35 which is driven through an idler 36 from a gear 37 fixed on the rear end of a. shaft 38. The latter is rotatably mounted in frames 33 and at its forward end carries a gear 39 which is driven by a gear to rotatably mounted on the front frame 92 adjacent to frame Fixed to gear 40 is a gear ll which drives a gear l2 fixed on roll Z. The gears 37 and 39 preventseparation of frames 33, when removed, and the roll 2., being shouldered near its ends, prevents inward movement of the frames. The latter may be easily removed by pulling outwardly on pins 3% and then lifting the frames 83 above frames at and pushing them inwardly (to the left) until belt Z) is loosened sufficiently to allow the frames 33, and associated parts, to be removed from the loop of the belt.

The various moving parts, a sociated with the wire belt I), are all driven from a shaft 43 which extends from the driving mechanism, (mounted on a bed l at the upper part of easing A, Fig. 7), vertically downward near the front wall of the casing and carries at its lower end a bevel gear 45 (Figs. 3 and 10). Meshing with the latter is a bevel gear 46 fixed near one end, to a shaft 47 which extends horizontally across the casing and carries two sprockets 48, one on each side of belt Z1 (Fig. 10). Each sprocket 48 isconneeL-ed by a chain l: (Fig.

5) to other sprockets fixed to the ratchet wheels 19, whereby the rapping frames 1) and w are operated, and one chain 49 also extends to and drives a sprocket 5O rotatably mounted near the outer end of the front frame it. tiprocket 50 is fixed to a gear 51 which drives the gear -10, heretofore described, and thus the rolls '2' and t. Fixed to shaft 47 is a gear 52 (Figs. 3 and 5) which drives by idler intermediate gears 53 a gear 54 on a horizontal shaft 55. Shaft 55 is mounted at one end in the front wall of easing A. and at the other end in a bracket 56 and carries atits inner end a gear 5"? to drive the descril'ied gear 537 and thus both rolls Z. i

The wire belt drive shaft d3 extends above bed 44 and is connected by bevel gears 58 (Figs. 6 and 7) to a horizontal shaft 59, which has fixed thereon a series of gears 80, of graded sizes. Parallel with shaft 59 is a shaft 61 on which is slidaloly keyed a group of gears 62, one to correspond with each gear 60. The arrangement is such that any one of the gears 62 may be moved to mesh with one of gears whereby a selective change speed transmission from shaft 61 to shaft 59 is obtained and whereby the speed of the wire belt may be varied, as desired. A yoke 63, forked at one end to straddle gears 62, is threaded at its other end on a rod 6 rotatably mounted at its ends in the front and back walls of easing A and provided with a hand wheel 65, outside the casing, whereby it may be turned. Shaft 61 is driven by spur gears 66 from a shaft 67 mounted directly thercabove and shaft 67 is driven by a belt 68 and suitable pulleys from an electric motor 69 mounted on bed as.

The feed and delivery belts c and d are driven from shaft 59 through a selective gear transmissitm, whereby their speeds may be changed relatively to that of the wire belt 6. Referring to Fig. 8. a short shaft 70 is mounted directly below shaft 59 and he. fixed thereto a series of gears 71 of graded sizes. Jr corre pending group of gears 72 are provided on shaft 59. The corresponding gears of each group are always in mesh but only one of the gears 72 at a time can be keyed. to shaft 59. The latter is grooved to receive a sliding key 73 which can be moved axially and engaged with any one of gears 72. The key 73 is carried by a grooved collar 74: with which a shifter fork 75 is en gaged. Fork 75 is threaded on a rod 76, mounted similarly to rod 6st and provided, outside casing A, with hand wheel 77, whereby it may be turned to effect speed changes between shafts 59 and 70. The latcarries a sprocket 78 which is connected by a chain 79 with a sprocket 8G, rotatably mounted on a stud on the rear wall of casing A below belt 6. Fixed to sprocket 80 is a bevel gear 81 which meshes with a bevel gear on a horizontal shaft 82 disposed longitudinally of easing fraud behind and below belt 6. The ends of this shaft are provided with universal joint connections 83 and 8st to receive corresponding connections on the drive shafts for the feed and delivery belts respectively.

The drive for each belt is similar and a description of that for the feed belt will sufiice for both. Referring to Fig. 1, a shaft 85 is connected at one end to the uni.versal joint 83 and at the opposite end to a similar joint 86 which connects with a short shaft 87 mounted in brackets on a pedestal 88. The latter rotatably supports the drive roll 89 for belt a and the drive roll carries a worm wheel 90 driven by a worm 91 on a shaft 92, mounted on pedestal 88 above sl a it 87 and driven therefroni by spur gears 93. Shaft 85 is usually covered by a tube 94: on the ends of which are open ended cups and 96 to encompass the universal joint connections 8?) and 86, respectively. This tube, and the shaft therein. need to be removed for convenience in withdrawing the tank 6 through door in. The cup is held to its tube by a set screw 97 and, when this screw i U Q 41 will;

'83 and then to the right to disconnect it from joint 86.

The feed belt 0 is trained over a table comprising two sections 99 and 100, arranged end to end and hinged together at 101. The section 99 is pivotally connected at 102 to pedestal 88 and the opposite end of section 100 is supported by resting on brackets 103 on casing A. Stops 104 fixed to the sides of section 99 engage lugs 1.05 projecting outwardly from the lower face of section 100 and prevent the sections from downward jackknife movement and normally hold the sections in a common horizontal plane to support the feed belt in its upper stretch of travel. The sections, however, may be moved upwardly in jackknife fashion into the position shown by dotted lines in Fig. 1 and, when so moved, may be held in this position by brackets 106 on pedestal 88 which support the lower end of section 100. This operation can be quickly and conveniently performed without removing belt 0, and as a result, the space between pedestal 88 and easing A is cleared to facilitate the opera tion of withdrawing tank e.

The tank 6 is jacketed, as shown in Fig. 2, and is provided with a suitable stirrer, such as 108, which is fixed to the upper end of a centrally and vertically disposed shaft 109, which extends downwardly through a long hub 110 in tank 6, and through the floor of truck 7, and carries at its lower end a bevel gear 111. In mesh with the latter is a bevel pinion 112 fixed on one end of a shortshaft 113, mounted beneath the floor of truck 7 (Fig. 1). The rear wheels of the truck closely fit between tracks 114 on the bottom of easing A and stops 115 extend upwardly behind these wheels to arrest the same in proper position. When the truck is thus positioned, a clutch jaw 116 on shaft 113 is aligned with a mating jaw 117 fixed on one end of a shaft- 118 slidably mounted in one end of casing A and adapted to be moved endwise by a shift lever 119 to carry jaw 1.17 into engagement with jaw 116. Slidably keyed to shaft 118 is a sprocket 120 which is connected by a chain 121 to a sprocket 122, fixed on the described shaft 82, outside casing A, whereby the stirrer 108 is driven.

The bottom of tank 6 is connected, at one side, by a passage 123 (Fig. 2) to a vertically disposed cylindrical well 124, which loosely receives the lower end of the screw elevator tube 9. Fixed to the lower end of 1 ,ceraeo the latter is a fork shaped bracket 125 which receives, and forms a step bearing for, the lower end of the elevating screw it. The lower end of bracket 125, by abutment with the bottom of well 124, positions the tube 9 vertically. This tube is held from lateral displacement by a two part encompassing clamp, comprising a section 126 fixed to a side wall of easing A and a section 127 pivoted to section 126 at one end and adapted to .be held thereto at the other end by a clan'iping screw 128, all as shown in Fig. 3. By releasing screw 128, and swinging sec tion 127 outwardly, the tube g, while still in place in well 124, may be withdrawn from casing A when tank 6 is withdrawn, after which tube 1 can be removed by simply lifting it out of well 124.

In order to drive screw it in a manner such as to permit it to be quickly and conveniently disconnected for removal, when desired, the following mechanism is employed. The upper end of screw it is squared, as at 129, (Fig. 2) to fit in a correspondingly formed socket in a member 130, fixed to the lower end of a short vertical shaft 131. The latter extends through the bed 44 and is slidably keyed to a bevel gear 132. The weight of part 130 normally holds it in engagement with the squared end 129 but it may be disengaged therefrom by lifting shaft 131 until the key 133 is drawn out of gear 132. By then turning shaft 131 far enough to carry key 133 out of alignment with its keyway in gear 132, the part 130 is held in raised position so that tube 9 and screw it may be withdrawn from cars ing A. Gear 132 meshes with a bevel gear 134 (Figs. 6 and 7) fixed to one end of a short horizontal shaft 135 mounted in bearings upon bed 44. The other end of shaft 135 carries a bevel gear 136 which meshes with a bevel gear 137. The gear 137 is fixed to the hub of a clutch jaw 138 and the latter is loosely mounted on the shaft 61, above described. Slidably keyed to shaft 61 is a mating clutch jaw 139 which is movable by means of a shifter fork 140 into engagement with jaw 138. Fork 140 is fixed to a slidable rod 141 which extends outside casing A and carries an actuating handle 142.

The fan m is supported by brackets 143 (Fig. 2) secured to the lower face of bed 44 and disposed one at each end of the fan. On one end of the shaft 144 of the fan is a pulley 145 which is driven by a belt 146 from an electric motor 147 mounted on bed 44.

The shower pan has on each end an outwardly extending flange 148 (Figs. 1 and the angle irons 1et9 by andbetween pairs of upstanding pans 151 which engage the ends of flanges M8.

The tank emay be filled, while in place in casing A, by u'ieans of a trough 152 2) the mouth of which. is disposed outside casing A and the exit end of which overlies the top of the tank.

The casing i l-is entirely closed on the front and rear sides. The lower portion of the casing, forming the housing for tank 6 is permanently closed at one end and at the opposite end is closed by door A. Above the belt Z), suitable doors w and 3 are provided to close the end walls of the casing, except for small openings to permit the passageoi the confections into and out of the y y The operation of the machine, in so far as the coating of confections is concerned, is no 'diiferent than usual and will sutlicieritly appear from the foregoing description. The operation of removing the essential working parts of the machine is usually started by lifting the feed table sections 99 and 100 and moving them into their folded positions, illustrated by dotted lines in Fig. 1, which clears the space for the removal of thesupply tank a. The shaft 85 and its enclosing tube 94 are nextuncoupled, as already described The doors A and m are then opened to clear the way for the removal oftank e and. the screw elevator tube 1 The shaft 131 is pulled upwardly to disengage the member 130 from the squared end 129 of the screw elevator h and is turned to carry its key 133 out of line with the keyway in gear 132, whereby member 30 is held in raised position. The clamping screw 128 is loosened and swung free of clamp 127 and the latter swung outwardly to release tube 9, whereupon tank 6 with the tube {1 in place in well 124 may be rolled out of casing A,tl'1e tank being preferably first disconnected from its operating mechanism by Operating lever 119 to separate the clutch jaws 11.5 and 116. The shower pan 7' is then removed through the open door a: by lifting itfree from its angle iron supports 149. The removal of the wire belt and associated parts is started from the delivery end of the machine by removing frames 33. This is effected by firstpulling out pins 34: and then raising the frames until they clear the upper edges of frames 12, after which the frames33 are moved toward the feed end of the machine until there is slack enough in belt b to permit the frames 33, and rolls carried thereby, to be drawn laterally out of the loop of the endless belt 6. The frames 33, having been removed and the belt 5 left loose and free at one end, the rapping frames w and o, are successively removed in the order named. In removing these frames, they are simply lifted free of studs 18 and then withdrawn laterally from the loop of belt Z). The frame a is usually removed from the feed end of the machine after the frames 22, and the rolls carried thereby have been removed. To remove frames 22 they are simply lifted free of their angle iron supports 24:, and the pins 26 carried thereby, and then pulled endwise through door as. As these frames are pulled out, the rolls g and s drag belt 7) along with it and after the frames have been entirely withdrawn from casing it, they and their rolls may be withdrawn laterally from the loop of belt 5. ll 'ith frames 22 removed, access is readily had to frame a which is pulled out through door at and out of belt 5, after which the belt itself is completely drawn out. The operations described are far more easily and quickly accomplished than would appear from the description and a single operator can dismantle the machine, in the manner described, in a very few minutes. ll it-h the parts removed as described, an operator can enter casing r and clean the sides thereof, the adjacent stationary parts and any other parts which may become covered with chocolate: The cleaning can be easily and thoroughly done because the operator works under favorable conditions and everything is freely accessible for the purpose, alter stripping the casing of the main working parts as above described. 7 The parts removed can likewise be cleaned under favorable conditions. The group including frames 22 and the group including frames 33 can be cleaned as a unit without dismantling the individual parts. The elevator mechanism is, however, usually taken aoart. For this purpose the screw 9 is lifted out of tube It and the tube is then lifted out of well 12 1.

Aside from the mounting of the wire belt for convenient removal, which is an essential to the results sought to be accomplished, the arrangement for collapsing the feed belt table is thought to be particularly important. It is important, in any event to give free access to one end of the casing A to enable the removal of the wire belt to be the more readily performed, whether or not tank 6 is removable. It is also especially important to the practical and. successful use of a removable tank, particularly when there is associated therewith an elevating device which is drawn out with the tank in assembled relation. Such a tank and elevator cannot readily be withdrawn through the front and rear walls of the casing because these walls carry the bearings for a number of moving parts. One end of easing A is blocked by the extension frames n and, because of this fact and the fact that the elevator is adjacent the feed end of the machine, the removal of the elevator has to be effected from the feed end of the machine. This feed end, however, is blocked by the Cii n (If feed belt which, except for the collapsible arrangement described, would have to be removed as an entirety, necessitating the unbolting the pedestal 88 and the bodily shifting of a considerable weight.

The parts, removed from casing A as above described, may be reassembled therein by reversing the operations described and performing them in reverse order.
