CANDY-FORMING MACHINE.

Application filed January 4, 1921 Serial No. 434,868.

To all whom it may concern Be it known that 1, WILLIAM G. SMITH, a citizen of the United States, residing in Philadelphia, Pennsylvania, have invented certain Improvements in Candy-Forming'Machines, of which the following is a specification.

v My invention relates to improvements in candy forming machines of the type disclosed in the U. S. patent of J. Werner, No.

1,206,069, dated November 28,1916, the ob- 'ject of the present invention being to provide improved mechanism for automatically cutting and discharging the formed candies from the machine.

In the accompanying drawings: Figure 1, is a plan view of a machine madr in accordance with my invention;

Figs. 2 and 3, are, respectively, side elevations of the main portion of the machine;

Figs. 4 and 5, are vertical sections taken on the lines 44 and 5-5, respectively, Fig. 1, and 7 Figs. 6 and 7 are vertical sections similar, respectively, 7 5, with the exception that the forming rolls are shown in position for the discharge of the formed candy and the reception of a new blank. c With reference to the drawings, the machine consists of a supporting frame 1, upon which are mounted, one at each side ofsaid frame, bearing frames 2, 2, said bearing frames each having therein a horizontal slideway for the reception of movable journal- boxes 3 and 4, and a vertical slideway for the reception of a journal-box 5. I

Mounted in the bearings 3, 3, is a forming roll 6, while in the journal-boxes 4:, 4., is mounted a similar forming roll 7, said rolls having trunnions' 3 and 4:, respectively, mounted in said journals and forming bearings for the rolls, the trunnions at one side of the machine extending beyond the outer thereto bevel gears 8 and 9, respectively.

Mounted in the bearings 5, 5, isa supporting roll 10, said roll'having trunnions 5 mounted in the said journalsboxes, and the trunnion at one side of the roll extending beyond the outer face of the journal-box and having secured thereto a pinion 1'1.

As most clearly shown in Fig. 1, the form ing rolls are provided in the present instance to the sections of Figs. 4: and

edge of the j ournal-boxes and having secured I with narrow extending spaced fins 12, said fins being oppositely disposed upon the respective rolls whereby when the two rolls are brought together, the peripheral edges of the fins meet accurately, the size and shape of the candy particles depending upon the conformation of the spaces enclosed between the adjacent fins when the rolls are in contact.

Mounted in the bearing frames 2, one at each X side thereof, are set screws 17, 17 and 18, 18,

which respectively limit the outward movement of the sliding journal- boxes 3 and 4 in the slides.

The supporting roll 10 is formed with wide cylindrical extensions which are adapted to fit between the adjacent fins of the rolls 6 and 7, as most clearly shown in Figs. 1 and 5, these extensions forming supports for the candy which is acted upon and formed by I the three rolls operating conjunctively.

As shown in Fig. 4, the journal- boxes 5, 5, which are adapted to slide in the said vertical slideways, are supported in each case by a vertically disposed threaded rod 13,

the threads of said rods engaging corresponding threads formed in suitable openings 1n the frame 1. The said rods 13 are so secured in the journal-box 5 that rotation of i the rod with respect to the journal-box is permitted, while at the same time a firm connection is established. In the present instance, the upper end of the rod 18, which occupies a suitable recess in the journal, has

an annular recess 13, and pins 11- entenda ing into the journal-box occupy the opposite sides of the said recess, thereby preventing withdrawal of the rod 13, while permitting its free rotation with respect to the journaLbox. One of the rods 13 may have at the lower end an operating wheel 15,; and this [rod may be joined to the other by means of a sprockets 16, 16, one of which sprockets is fixed to each of the rods. I V

Mounted upon suitable pivots 19, 19, upon the supporting frames 2, one at eachside of the IDZLClllIlB, are bell crank levers 19219 one arm of which carries a journal block chain connection between 20 through which the trunnions 4, E, of the roll 7 extend respectively, saidarm also hav-v ing an extension 21, in which is mounted a roller 22. The other end of the said lever 19 has extending loosely through an aperture therein a pin 23, the lower end of which pin is rounded at 24 to permit it to slide easily'over the upper surfaceof the frame 1, and a spring 25 carried by said pin 23 is confined between the under side of the arm of the lever 19 and a collar or spring rest 26, the tendency-of the spring being to force the arm of the lever 19 upwardly so as to carry the opposite end of the lever together with the journal-box 20 and the journal-box 4 in which the said roll 7 is mounted, outwardly and away from the opposing roll 6.

A cam shaft 27 is mounted in suitable bearings 28 upon brackets 29,29, which are mounted one at each side of the frame, and the shaft 27 carries attached thereto, one at each side of the machine and in position to engage the rollers 22 upon the respective levers 19, cams 30, 30. The shaft 27 is adapted to revolve, and in doing so causes the cams to operate upon the lever arms 19 in such a manner as to reciprocate the roll 7 backwardly and forwardly in the frame 2 so as to alternately bring the finsthereon in contact with the corresponding fins of the roll 6 and to separate them. The cams 30 are so formed that the movement of the roll 7 away from the roll 6 is rapid, after which it is slowly fed back into position in which the fins contact.

One of the trunnions 5 of the roll 10 is extended and carries at the outer end thereof a pulley wheel 31 which, by means of a belt (not shown) may be operably con' nected with anysuitable source of motive power. Carried also upon the said trunnion is a bevel gear 32, which is adapted to mesh with a bevel gear 33 upon a shaft 34 carried in suitable bearings 35,35, upon a bracket 36 attached to one of the brackets 29, said shaft 34 having at the outer end thereof a worm 37, which is adapted to mesh with a worm wheel 38 secured to the cam shaft 27. By this means the roll 10 and the cam shaft are interconnected and rotated.

Rotation of the forming rolls 6 and 7 is accomplished by the pinion 11 upon the supporting roll trunnion, and by the pinions 8 and 9, respectively, upon the trunnions of the rolls 3 and 4. Links 39, 39, and 40, 40, are loosely mounted upon the trunnion of the said supporting roll 10, and at the outer ends of these links are suitably mounted 7 pinions 41 and 42, respectively. Links 43,43, and 44, 44, are loosely mounted respectively upon the trunnions 4 and 3 of the rolls 7 and 6, and are secured to the outer ends of the links 39 and 40, the pinions 41 and 42 intermeshing respectively with the gear 11 and respectively with the gears 8 and 9. This arrangement will be more readily understood by reference to Fig. 3 of the drawings. From this figure, it will be i seen that as the pinion 9 moves outwardly With'the roll 7, the links 43 and 39 retain the pinion 41 in mesh with the said pinion 9 and with the pinion 11 whereby there is a continuous operative connection, this applying similarly to the pinion 42 which is continuallyin mesh with the pinion 11 and the pinion 8, regardless of any adjustment that may be made of the latter pinion.

The top portions 47 of the bearing frames 2 are pivoted at 45 whereby the said top elements may be lifted away to permit removal of the journal-boxes and of the various rolls, a pin 46 in each case locking the free end of the top 47 to the frame 2.

The operation of the device is as follows: lVhen the rolls are in the positions shown in Fig. 7, an operator places a blank roll of candy, indicated by the numeral 48, between the said rolls 6 and 7, this candy blank having been placed upon a platform 49 and simply rolled into place between the rolls at the appropriate time. As the cams rotate, the roll 7 is moved slowly inwardly towards the roll 6, the candy which is supported by the fins of the rolls to drop downwardly between the supporting roll 10 and the roll 7 into a trough or chute 50, which guides it to a. suitable receptacle. The direction of rotation of the rolls assists the discharge. .At this point, the operator drops another blank of candy between the rolls, which blank is supported by the supporting roll 10 and is prevented from falling into the chute by the extending fins of the roll 7, and the above described operation is repeated.

It will be noted that'the formation and discharge fromthe machine of the candy particles is entirely automatic, all that is required of any operator being the feeding to the machine of the blanks. I V I The inner edge of the platform 49 is turned downward, the edge being slotted to form a comb, the fins 12 of the roll 6fitting into the slots. A similar comb-like bar is mounted-above the roll 7, the two combs forming the mouth of a hopper into which the unformed bar of candy is dropped. These combs primarily act to loosen any formed pieces of candy that may adhere to the rolls when they are opened to discharge the finished candy pieces.
