Specification of Letters Patent.

Patented May 9,1911.

Application filed January 17, 1810. Serial 80. 538,551.

To all whom it may cor-earn: 5

Be it known that I, Jonx Wrasse, a citizen of the United States, and resident of Rochester, in the county of Monroe and State .if New York, have invented certain new and useful Improvements in Candy- (rniting Machines, of which the following is a specification.

This invention relates to machines of the t )8 in which candy centers are coated with climtolaie, or other niaterial.

The oticct of the invention is to produce a machine of this character which shall be simple in constructionand efiicient in operntion.

The novel features include means for maintaining automatically an even temperature in the meltin tank, means for costin the under side 0% the candies evenly 'and tioronghly, means for placing candy in the machine to be mated, and meansfor removing it therefrom.

Inythc drawings :-Fignre 1 is a plan view of a machine embodying the present invention; Fig. 2 is a side elevation of the machine of Fig. 1; Fig. 3 is an enlarged sec.- tion on the line 3-3 of Fig. 2; Fig. 4 is an elevation of part of the machine, from the side opposite to that. shown in Fig. 2; Fig. 5 is a longitudinal section on the line 5-5 of Fig. 3: Fig. 6 is an enlarged view of the distributing mechanism by which the candy is removed from the machine; Fig. 7 is a detail view of the carrying forks, in elevation; Fig. 8 is an end View of the forks: Fig. 9 is' a plan view of the forks; Fig. 10 is a perspective view of one of the candyholdcrs. with candi s on it, as it appears when placed in the machine; Figfll is a diagrami'aazic view of the temperaturercgnlator; Fig. i2 is an enlarged elevation of ertain parts slmwn in Fig. 2; and Fig. 13 is a plan view of certain parts shown in Fig. 12.

in Figs. 1 and where the complete machine is rcprcsentml. 1 indicates the coating mechanism, thrdistrilnlting table, and 3 the feed-table.

'l'ln: candy rotors X that are to be coated are laced in racks 4 (Fig. 10), divided at equal intervals by transverse rihs The racks are thin and (lat. and preferably made of wood. Operators till these racks with unmated candi s, and then place them upon a belt 6 (Fig. 1) that moves continuously,

' as indicated by the arrows, and is actu t d from a dri en shaft 7. The belt 6 runs over an idler 8 at one side of the machine, and a similar idler at the end of the feed-table, which is not; shown in the drawings.

The. operator stands at the end of the machine betwen the feedtable 3 and the idler S, and taltesjhe racks full of candies as they approach him. sliding the candies oil the racks onto a elt that moves in the direction of the length of the machine, carrying the candies through the coating mechanism. Having removed the candies from the racks, the operator places the empty racks on the opposite side of the belt 6, which is moving toward the feed-table, and they are returned tube filled at the latter.

The prongs of the carrier-forks are preferably made from flat. pieces of metal that are twisted near the ends 10 at right angles to the main portions 9, so that the main portion; 9 support the candies on their edges, and the parts 10 can be secured between two transverse bars 11 and 12 (F ig. 7), which latter are fastened together by screws 13. 9 turned down over the bar 12 at their rear ends, so that they cannot fall out when the screws are set n The bars 11 and 12 which extend across the machine, as aforesaid, are fixed at each end to blocks 14, while the latter are connected to endless chains 15, 15 that run over sprockets 16 and 1'! (Fig. 5). These sprockets in turn are fixed, respectively, to transverse shafts 18 and 19 th' are ournalcd in the side frames 2 l0f the machine. The shaft 19 is rotated intermittently by a mtchet gear 21 (Fig. 2. that meshes with a pinion 22 on one end of said shaft. outside the frame 20. The gear 21 is actuated by a rockerarm .23., that is connected to an ccentric 24 on a drive shaft The pinion 22 is thus given intermittent movement, which it, communicates to the chains 15, so that the forks move through the machine one step at a time, and the parts are so proportioned that each step is 0: ual. in length to the distance from the tip o one set of prongs to the tip of the next. set. The candies are placed on the forks while the latter are momentarily stationary between the movements. Below the chains 15 and inclosing them on all sides but the top, is a hopper 26 (Fig. 5) that contains the melted chocolate, or other coating material. Connected to the bottom of this hopper by a. pipe 27 is a gear pump 28, driven The drawings show the prongs.

from the drive shaft. 7 (Fig. 4). 2S draws chocolate continuously from the bottom of the hopperand .forccs it up through a pipe 30 and into the side of :1 casing 31 that extends across the top of the machine. This casing 31 has a slot 32 on its under side, that extends across the machine (Fig. 5), in which a bar 33 lies that is adjustahle vertically by means of thumlr screws 34, to regulate the flow of chocolate. \Vhen the bar 33 is raised, a sheet of chocolatein fluid state flows continuously through the slot, down into the hopper, and between the prongs 9. As the candles 2x pass through this sheet of chocolate,v they become completely coated except, on the bottom. For the purposeof coating the bottom also, a

plate is pivoted at. 3-6 under the chains 15, and it. rear edge 18 held up against the under side of the forks by a counterweight 37 (Figs. 4 and 5). This plate is directly under the slot 32, so that itbeeomes thickly covered with chocolate, which it presses up through the forks. The candies in passing over the plate are accordingly dragged across the chocolate that it presses up betwccrf the forks, and in this way are thoroughly coated on th bottom. When the chocolate piled up on the plate 35 overcomes the counterweight 37, the plate tilts and lets the choc-date slide oil into the hopper. The surplus chocolate in the casing 31, that canno-I pass through the slot 32, runs back to the hopper through a pipe 38 (Fig.

A thermometer 39, set in the top of the pi": a., discloses to the operator the temperature of the chocolate. It, is essential to maintain the temperature of the chocolate practimlly constant, and the machine is designed to accomplish this in the following manner: in the first place, the machine is inclosed air-tight by its outer frame 20, and heating steam-coils 40 are placed on the floor under the hopper 26, but not in cont'act with it. The heat of the coils may vary, but inasmuch as the air between them and the hoppcr is a comparatively poor heat conductor, the llzuztuaticns at. the hopper are reduced. Next, the circulation of the chocolate by the pump 23, as tlt'rtlllmtl almve, tends to main- 7 tain an even temperature, and finally, the

device constituting the armature 4".) of anelectromugni-t 50. The clectromagnct, when encrgizwl,operates tit-a r cment to release the. rahihct monu-ntarilr and the eccentric 4-1- makcs a' halt rotation o der he movement imparted to it h the spring motor, and so raises the rod and opens the valve 42. 'l'hc magnet controlled by a thermometer 51, located between the hopper Iii and the frame 20. The mercury in this thermometer is divided by an air space into two parts 52 and and the terminals 54 and-55 fromja battery 56 enter the tube as indi- 'cated in Fig. 11. When the temperature drops to a predetermined point, the part 52 of the mercury closes a circuit between the terminals .34 and 55, and operates the magnet 50, which, as explained, opens the valve 42', and admits steam to the coils -10. \Vhen point, the part 53 closes the circuit and the magnet operates the escapement again and permits the eccentric 46 to make a half-rotation. and op rate the rod-45 and lever 43, closing thevalve 42 again. I

The apparatus which receives and distributcs the candies after they have been coated, eonsistsof' a frame 57 (Figs; 2 and 1-2), which has at its rear. end a rotatable drum 58, and at the forward end, adjacent to the frame 20., a roller 59. A tight canvas belt. 60 runs over the roller and drum, and is can ried alongslep by step as the latter is intermittentlyrotated. "Intermittent rotation is cficctcd by a ratchet disk 61., actuated by a pawl 62, which receives its movement. from a rocking link 63, which latter is swung back and forth by a rod 64. The rod 64 is connected to an arm 65 that is oscillated by a rod 66 from the eccentric 24 (Fig. 1). By moving the end of the rod 64 to various po sitions on the link 63 where it is secured in 105 place by a nut 67, the drum may be made to mme the belt (30 in longer or shorter steps as desired. 1

()n the upper face of the hell (it), spaced at equal intervals, and arranged in pairgacross it, are hooks 68 (Fig. 6) each paii being adapted to enter perforations at one edge of a sheet of paper Y, that is placed on the hooks by, an operator seated at the table-leaf (39 (Fig. 1). 57 are idler rollers 70, 71, 7:2, provided with adjusting or tension screws, while just behind thcroller 5!); located at the forward end of said frame, is an idler 73. A belt 74 runs over these rollers, and the drum 58. so that 120 At the rear end of the frame 1 5 forksonto the paper Y. The parts are so timed that the paper Y moves and stops as the forks do. In this way the candies are placed on the paper Y in even rows, and as they stop momentarily under the stamps 78, are marked with the form on the die. The frame 77 is adjustable. vertically upon the arm 76 that is pivoted to the lever 73 and is fixed in adjusted position by set screws '57". The stamps are hung in the frame by means of freely sliding vertical stems, as shown in placed on the tops of the candies and then r Fig. so that as the frame descends they are picked up again. as the frame is raised. The

standards 7'4", .7 serve as vertical guides for the frame 77. It is not neces iry that ,the spacing of the candies longitudinally upon the paper Y should be the sameas the spacing on the forks, for by using an appropriste ra jlgfi -fil, the spaces will be shortcried, or lerltherled. as desired. The ratchet '61 must have a smooth portion 83 to allow for 'the spacing between two (c.lii iiltl'f. sheets of paper, and the papers should be spaced :1 distance apart equal to three or four rows of candy, in order to give the operator at the table 69 time to remove w' full sheet and substitute an empty one.

In order to maintain an uninterrupted movement of the belts 60 and 74 during the time while the papers are changed, so that each paper will be brought ar'mnz] the roller 59 in time to receive its first row of candies.

a ratchet Si (Fig; 13) is fixed on the same shaft with the ratchet 'f-L and has a toothed portion opposite the smooth portion of the latter ratchet. and vice versa. The ratchet 84 is operated by a dog on an arm 86 that is connected by a rod 8? to the arm 65, so as to mo've in opposition to the rod 34.

A fan Fig. 5) is jrni :alcd in a casing adjac lit to the casing 31, and is revolved by a beit 5'") {Fig.2. 4) from the shaft 29. The fan draws-air through a p pe 91 from the space between the hopper and the frame 20. and blows it over the candy after it has been coated. The candy is subjected to this air current before it is acted upon by the bar 83, and is hardened in this way so that it is not Infll'IDl-d by the contact of said bar 53.

An agitator or shaker is provided to vibrats the chains 15 and forks for the purpose of shaking the surplus coating from the candies. This agitator consists of a air of star wiieis' 92 ,(Fig. 5) carried by a s mft substantially at.

213. The shaft. is rotated by a chain (Fig. 4-), and the star wheels shake the cl'iains 15 up and down.

A treadle 9% is provi iug frame for disconnecting that part of the mechanism from the driven shaft when necessary. This treadie is connected with a rod 95, which carries a hook 93 adapted to disengage. a clutch .fe' (Fig. t), When said hook is moved toward the drive shaft. 25. Any suitable form of clutch may be used that will disconnect the driving pulley from the drive shaft. A lzan'l lever 98 and a treadle lever 99 are provided at the feed .end of the machine for operating this clutch 97 from that end of the machine. both le ers being connected with said clutch 9? by a rod 106.

Means are provided for maintaining the candies in proper lateral relation while they are being' agitated, these means comprising thin, stationary bars 101. that depend from cross-pieces 30?. (Figs. 3 and and are spaced iaterully to correspond will. the ribs 5 on the racks 4. so that they keep the candics ape rt while passir through the coating mechanism even tho.
