JOI-IANN TRAUGOTT I-IOI-IBERGER, OF CHICAGO, ILLINOIS, ASSIGNOR, BY DIRECT AND MESNE ASSIGNMENTS, TO ARTHUR R. MORSE, OF CHICAGO, ILLINOIS.

CANDY-CUTTING MACHINE.

To all whom it may concern Be it known that I, JOHANN TRAUGOTT Honnnnenn, a, subject of the Emperor of Germany, residing at Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Candy-Cutting Machines, of which the following is a description. I

My invention-relates to'means for dividing, cutting, or otherwise suit-ably forming into pieces of suitable length a strip of candy or like material preferably while the same is in a plastic or semi-plastic condition. The object of my invention is to provide a simple, durable, and efficient device of the kind described wherein the relative movements of the cooperating cutting blades as they approach each other during the cutting operation are arranged to suit the requirements of the particular material upon which the device is adapted to operate.

To this end my invention consists in the novel construction, arrangement, and combination of parts herein shown and described, and more particularly pointed out in the claims.

In the accompanying drawings, wherein like or similar reference characters indicate like or corresponding parts; Figure 1 is a side elevation of mydevice. Fig. 2 is a top plan view of the samev with parts removed and broken away to more clearly show the construction. Fig. 3 is a perspective view of the cover, or outer cam plate for assisting in controlling the movement of the cutting blades. Fig. 4; is a perspective detail of the stationary inner cam for assisting in controlling the movement of the blades. Figs. 5 and 6 are details of the inner cam support and itsassociated parts. Fig. 7 is a detail of a portion of one of the blade carrying members. Fig. 8 is a perspective detail of a blade. Fig. 9 is an enlarged section taken substantially on line 9-9 of Fig. 1; and Fig. 10 is an enlarged section through the cutting heads taken substantially on line 1010 of Fig. 2.

In the preferred form shown in the drawings, my device consists of a pair of rotatable shafts 1 and 2, each mounted in suitable Specification of Letters Patent.

bearings upon the frame of the machine. Cutter heads or members 4 and 5 are mounted upon the extremities of the shafts 1 and 2 respectively and are each rigidly secured thereto, the relative position of the parts being such that the periphery of the members 4: and 5 will be brought into suitable relation with each other so that the cutting blades 6-6 positioned upon each head will be brought into suitable relation with each other to substantially sever the material passing between them. The heads 4: and 5 may be of anyv suitable construction and are preferably substantially similar. As shown each of the heads is provided with a peripheral wall 7 having a concentric flange 8 projecting at each side, a web or plate 9 having a central hub 10 is formed integral with or rigidly secured to the wall 7 for securing the head in position upon the shaft, and an inwardly projecting flange 11 is provided at the opposite edge of the wall 7 thereby providing a chamber 12 within each head between the plate 9 and flange 11 extending to the wall 7 Any desired number of substantially radial or otherwise suitably arranged slots 14.- are provided in the periphery ofeach head extending inward beyond the wall 7 and terminating at a substantially uniform distance from the center of the member. The blades 6-6 which are preferably of substantially uniform width are positioned in these slots and adapted to move substantially radially of the member.

Any suitable means may be provided for controlling the position and movements of the blades 6 in the heads 4 and 5. As shown a pair of plates 15 and 16 are secured to the outer face of each member to close the ends of the slots 14: and control the transverse position of the blades 6 in their respective slots.

The radial position of the blades may be controlled in any desired manner, as shown a pair of stationary cams or guides are provided adapted to engage the blades between them. In this form a cam 17 or equivalent means is rigidly positioned in each chamber 12 so that as the head revolves the inner edge of the blades 6 will successively engage the face of the cam to force them outward. A cover plate or cam 18 is arranged to par tially inclose the members 4 and 5, suitably formed to engage the outer edges of the blades 6 to control the outward movement thereof. In the form shown, the cam 18 is formed to hold the blades snugly at the inner limit of their movement in their respective grooves 14 until they arrive at a point where the blades engage the cam 17; at this point the cam 18 is formed to correspond with the form of the cam 17 so that at this point the cams coiiperate first to move the blades outward and then to return each blade to its normal position, the movement corresponding to the peculiar form of the cams. Obv ously these cams may be formed to provide for any desired movement of the blades at anypoint in the rotation of each head depending upon the particular material upon which it is intended that the machine is to operate. In the form shown, these blades are arranged to move outward to substantially the limit of their movement, after which they are permitted toreturn to their normal position in the member the return movement being so adjusted that the cooperating blades will approach each other with a substantially uniform movement.

Any suitable means may be provided for directing the material to be operated upon into the space between the members 4 and 5. In the form shown, a suitable opening 19 is provided in the plate 18 and an inclined curved lip 20 arranged to direct the material to, and support and control the same until it is engaged by, the blades 6, a suitable opening 21 is also provided at the opposite side of the plate 18 to permit the discharge of the material from the space between the members. A guide or chute 22 is provided to direct the discharged material onto a conveyer or other suitable means for disposing of the same.

Any suitable means may be provided for supporting the various parts in position. In the form shown, two brackets 24 and 24 are provided each rigidly secured to a base or foundation plate 26. The shaft 1 is supported in suit-able bearings formed integral with or rigidly secured to the respective brackets. The .shaft 2 may be similarly mounted, but in the preferred construction shown, a suitable opening 29 is provided in each of the brackets with the top and bottom wall of each opening substantially horizontal. A bearing 30 of suitable height to snugly fit within the opening 29 and arranged to move horizontally therein to permit of side adjustment is provided. Suitable means are provided for controlling the position of the bearing 30 in the opening 29. In the bracket 24 adjusting screws 31 and 32 are provided at opposite ends of the opening adapted to engage the bearings between them and accurately control its position in the opening. In the bracket 25- however, as the pressure due to the operation of the machine always tends to separate the members 4 and 5, a suitable pocket is provided at the end of the opening 29 adjacent the bearing 28 and a spring 33 is positioned with one end in the pocket and its opposite end projecting into the opening 29 adapted to engage the bearing to resiliently force the same toward the opposite end of the opening. An adjusting screw 34 is provided in the opposite end of the opening to engage the bearing and accurately limit its movement in that direction.

The members 4 and 5 may be secured to the shafts 1 and 2 in any suitable manner. In the form shown, a fixed key or projection 35 is provided upon the shaft 1 and a corresponding slot is formed in the hub 10 of the member 4 to cooperate with the projection 35 to prevent rotation between the shaft and member. A set-screw 36 is also provided in the hub, arranged to engage the projection 35 or other suitable portion of the shaft and prevent longitudinal movement between the head and shaft.

The member 5 may be attached to the shaft 2 in the manner above described, but it is obvious that in a device of this charac ter it is desirable that the cutting edge of the cooperating blades 6 should accurately meet to secure the most satisfactory operation. For this reason means are preferably provided for adjusting the rotary position of one of the heads upon its shaft. In the other form shown, suitable slot-s 37-37 are provided'in that portion of the shaft 2 projecting beyond the bearing 30 and a pair of set-screws 38 and 39 are provided in the hub 10 of the member 5 each arranged to enter one of the slots and engage the part 40 of the shaft so that by loosening one setscrew and tightening the other the member 5 may be slightly rotated upon the shaft so as to adjust the relation of the blade 6 in the head 5 with those upon the head 4.

The cover plate or cam 18 may be supported in any desired manner. In the form shown a plurality of arms 45 are rigidly secured at one end to the plate 18 and at their opposite ends to the bracket 25. The space in the cover plate 18 for the head 5 is preferably of suitable form to permit sufficient lateral adjustment of the head to suit the different kinds or conditions of material to be operated upon.

The cams 17 may be rigidly supported in position within the heads 4 and. 5 in any desired manner. In the form shown, each cam is provided with a stem 46 positioned slightly to one side of its center line with the side of the stem adjacent the center line slightly wider than the opposite side and adapted to be engaged by astationary member extending into the chamber 12 for this purpose. Any suitable means 'may be pro vided for engaging the stem 46 to support the cams 17 in position. As shown a cylin-- drical tubular member 47 is provided having a jaw or face A8 at one end formed to cooperate with'the stem 46 (see Figs. 5 and 6). A rod 49 is also provided formed to snugly fit'the interior of the part 47 and provided with a head 50 preferably of substantially the same diameter as the part 47 and having a jaw or face 51 adapted to cotjperate with the jaw 48 to form a substantially dove-tail clamp of suitable size and form to engage the shank 4:6.

The relative position of the parts A? and 49 to produce the desired clamping action may be controlled in any suitable manner. In the form shown, the rod 49 is of sufficient length to extend entirely through the member 47 and its extremity is threaded and provided with a suitable nut 56 adapted to bear against the end of the part 47 to draw the head 50 firmly toward the part 47 to firmly clamp the stem 46 between them.

Any suitable means may be provided to support the parts 47 and 49 in position. In the form shown, a stand 52 is provided upon the base plate 26 with suitable bearings 53-53 formed therein each adapted to receive the part 47. A set-screw 54 or other suitable means is provided in the wall of each of thebearings 53 adapted to engage the part 4C7 to rigidly hold the same in position in the bearing.

The free end of each-0f the cam supports.

may be held against transverse movement in any desired manner to insure the satisfactory operation of this portion of the device. In the form shown the central bore of each head extends entirely through the hub 10 and plate 9, but the shaft upon which each head or member 4: and 5 is mounted does not extend to the inner face of the plate 9 thereby leaving a slight central recess in the plate 9 adapted to engage a port-ion of the head 50, which is formed to fit the recess, thereby rigidly supporting the cam in position. As shown a project-ion 55 is provided upon the central portion of the plate 9 within the chamber 12 to increase the depth of the recess above described.

Any suitable means may be provided for rotating the shafts 1 and 2. In the form shown, a pair of gears 5 57 are mounted upon and rigidly secured to the shafts 1 and 2 respectively and a drive shaft 58 is rotatably mounted in suitable bearings upon the brackets 24 and 25 with a pinion 59 rigidly secured thereto and arranged to mesh with one of the gears 57. Any suitablemeans may be provided for rotating the shaft 58. As shown a belt-pulley 60 is rigidly secured to the shaft so that my device may be connected by a belt or other suitable transmitting means to any suitable source .of power (not shown) for operating the same. If desired a similar pulley 61 may be, loosely mounted upon the shaft 58 so that when it is desired to stop the machine the driving belt may be shifted to this loose pulley. A belt shifter 62 of the usual "form is shown in suitable brackets upon the plate 26 for directing the belt from one pulley to the other.

The material after passing between the heads 4: and 5 as hereinbefore described is received upon a carrier or belt 23 which moves it to any desired point and'discharges the separate pieces into a suitable receptacle. The conveyer may be of any desired form or construction. In the form shown the belt 23 is arranged upon a pair of pulleys 63 and 64 suitably arranged to hold the belt at the proper tension. The pulley 63 is secured to a shaft 65 rotatably mounted in suitable bearings upon the brackets 24.- and 25. A gear or pinion 66 is also secured to the shaft 65 and arranged to mesh with the pinion 59 to drive the conveyer. The pulley 64: is secured to a shaft 67 rotatably mounted in suitable bearings upon a stand 68 at the opposite or discharge end of the conveyer. The upper portion of the belt 28 extends through a box, trough, or other suitable means 69 with walls or parts provided on each side of the belt adapted to hold the material upon the belt until it reaches the end of the conveyer and is discharged.

In the preferred construction shown the heads 4 and 5 rial passing between them is not entirely severed, and the conveyer 23 is of sufficient length to permit the material to harden sufficiently, so that when it arrives at the end of the conveyer the material will break apart as it leaves the conveyer. Any suitable means may be provided to insure the cooling or hardening of the material upon the conveyer. In the form shown an air pipe 70 is provided attached to a blower or other convenient source of compressed air, (not shown) and extends preferably substanti ally parallel to and slightly above the box or trough 69. A plurality of openings or nozzles 71 are provided in the bottom of the pipe 7 0 by which the air from the tube is directed upon the material in the trough. The end 7 2 of the pipe 70 is preferably only slightly contracted or left entirely open, and so positioned as to direct a blast of air into the receptacle arranged for receiving the severed material from my machine to prevent the warmth of the interior of the material from tending to soften its exterior.

As shown a slide 73 is provided upon the are so adjusted that the matestand 68 and a suitable beater 74 is provided having a plurality of arms 75 adapted to successively strike the material passingover the pulley 64: to insure the detachment of the severed pieces. Each of the arms 75 is preferably provided wit-h a brush or wiper 76 at its outer end for engaging the material so as to avoid breaking or marring the same.

Any suit-able means may be provided for rotating the beater 74. In the form shown, the shaft 67 is extended beyond the bracket 68 and provided with a gear 77 adapted to mesh with a pinion 78 rigidly secured to a shaft 7 9 rotatably mounted upon the stand 68 and to which the beater 74 is also secured.

Having thus described my improvement, it is obvious that various immaterial modifications may be made in my device without departing from the spirit of my invention, hence I do not wish to be understood as limiting myself to the exact form and construction shown.
