To all whom may concern.:-

Be it known that I, GEORGE K. BAINBRID'GE, a citizen of the United States, residing at San Francisco, in the county of San Francisco, State of California, have invented a new and useful Cutting and Rolling Machine for Plastic Materials, of which the following is a specification in such full and clear terms as will enable those skilled in the art to construct and use the same.

4This invention relates to a machine vfor cutting and rolling plastlc materlals such as'cream candies which must be surfacedplete machine, Fig. 2 is a plan view of the complete machine, Fig. 3 is a sectional view of the cutter and that portion of the machine which rolls the cut-off lumps of material, Fig. 4 is a vertical sectional view on the line 4-4, Fig. 2, Fig. 5 is a sectional view 'illustrating the supporting shaft upon which the u per belt frame slides, Fig. 6 is a sectiona view illustrating the mounting of one of the rollers in the frames carrying the same, and Fig. 7 is a vertical sectional view illustrating another of the rollers carrying the rolling belt.

The numeral 1 represents a suitable base vupon which the machine is mounted. This base has a pair of inverted Urshaped frames 2 and 3, which frames support longitudinally extending bars 4.and which bars form the support for two roller shafts 6 and 7.v The bars 4 and 5 are braced-by means of two bars 8 and 9 which are bolted to the frames 2 and 3 respectively. Connecting the bars 4 and 5 are crosspieces 10, 11,

and 12 which form a support forthe door 13 .upon which the endless belt 14 travels.

The endless belt 14 passes' around rollers 15, 16 and over a 'small roll 17, which latter prevents the belt from saggin The shaft 6 is carried in ioxes 20, 21

which are adjusted by means of the threaded bolts 22, 23, suitable nuts 24,25 being used to draw the roll up andhold the belt tight. The shaft 7 has a pulley 26 thereon for drivlng 1t, said pulley' receiving power from a belt 27 which passes around a multiple pulley 28 on a short shaft 29 supported by the brace 8.

At the upper part ofthe frame there is secured a flat top member 30 for the support of the operating parts of the upper belt. This member 30 is adjustably supported by means of bolts 31, 32, 33 and 34 which bolts have nuts thereon in Contact with the upper member of the U frames supporting the belt. On the sides the frames 2 and 3 support a horizontal bar 36 which bar supports a bracket 37 through which a shaft 38 extends, said shaft supporting two rollers 39, 40 over which a belt 41 extends from the multiple pulley 28 to a pulley 42 on the upper end of the crank shaft 43. The crank shaft is journaled in a box 44 suitably secured tothe top lmember 30 and its lower end is connected to a shallow U shaped frame 45 in such manner as to permit it to rotate in said frame 45 and thus give a gyratory motion to the upper belt.

The upper belt is supported from -the member 30 by means of four depending arms 46,47, 48 and 49. Said arms carry two hori' zontal shafts 50,v 51, on which shaft-s two longitudinally extending bars 52, 53 are Y slidablc, said bars having outturned lugs at the ends as indicated at 54, 55 through which said shafts 50, 51 respectively pass. The bars 52, 53 are rigidly connected by two cross shafts 60, 61. The frame which supportsv the upper belt comprises two longitudinally extending bars 62, 63 rigidly connected together by means of the bolts 64, 65. This frame carries rollers 66, 67 at its ends, the latter beingadjustable, and the bars 62, 63 are slidable on the bars 60, 61, which latter bars are connected with the supports 52, 53 slidable on the longitudinally extending rods 50, 51, so that the components of ai lateral and longitudinal slide of the belt frame imparted by the shaft 43 and frame 45 will be a circular or gyratory movement.

The roll 67 is supported upon a shaft 68 which shaft is journaled in suitable bearings 6 9, 7 0,which bearings are rigidly connected to the threaded. bolts- 71, 72 andv which bolts are acted upon by the nuts 7 3,74y forshifting the roll 67 and tightening the belt 76 carried thereby. IThe roll 66 has a worm wheel 77 on its shaft at one end, which worm wheel is operated by the worm 78 on a flexible shaft 79, the latter shaft having as a bearing a bracket `8O. and having its other end connected by means of a coupling 81 to the .top of the crank shaft 43.

The Hat member 3() carries a receptacle 8 for the comminuted material used for surfacing the lumps of material to be treated bythe machine. This receptacle has a shaft 84 extendin-Or thereinto which shaft is supported by the bearing block'85 and driven from the pulley 86 by means of the belt 87 two brackets 92, 93 which support a base 94 rack piston rod 107, said rod through a suitable support at 108 andbeing for the press cylinder 95. .It is to be observedthat the particular type of press is immaterial to the invention, the only requisite being that the press and surfacing machine be driven. in' such harmony as to cut off the right lengths of the plastic-material and adequately surface them as they pass out from their treatment bythe two belts. ln the present instance the base 94 is extended over the top of the lower belt as indicated atV 96, at which point it has a pair ,of bearings 98, 99zfor a shaft 100, which.

shaft carries arms 101, 102 for the'support of the cutting wire 103. The cylinder has a spout 104 which extends into proximity of the path, of the cutting wire 103 so that as fast as the material is forced out of the press it be cut off into small lumps by the wire 103.

The press has a piston 106 operated bythe passing driven by a gear 109 on a shaft 110. l.The shaft 110 has a' squared portion 111 to enable the piston to be withdrawn by manually sliding the driving gear 1121 onf-he feather 112' out of engagement with the plston.`

small pinion 113, a small hand crank being applied to the shaft 110 for on the base 1-which motor has a belt -114in mesh with the'pulleyll, a smaller pulley A" thereon, over which a chain 121 passes to a sprocketgear 122 onthe shaft 100, said retracting the Y shaft also carrying apulley 123 around which the cross'belt 124 extends, said belt extending to the multiple pulley 28 for ydriving the machine. v

The operation of the machine is as follows: The cylinder 95 havingbeen filled with the plastic material to be treated, the piston 106 is placed therein and turned up by means of a suitable hand crank, not shown,- until the piston engages the plastic material, whereupon the motor may be started and as it runs the. piston will be pushed forward, while at the same timev the belts will be caused to travel forward, the upper belt having a gyratory `motion imparted thereto by the crank 43. At the same time the arms 101, 102 will be rotated so that small lumps of the material .pushed out of the press will drop upon the belt 14 and as it travels forward they will be rolled in l the surfacing material that is dropped upon they upper belt from the receptacle 83,A so

that when they leave the machine they are properly rounded to be given such other treatment as may become necessary. At the same time that the belt 76 is given the gyratory'motion it is also given a slow longitudinal motion by means of the flexible shaft 79 and it receives the comminuted material for the treatment ofthe lumps, thereby continually offering a freshly dusted sur/-l face to the lumps to be treated, the lower belt moving them through the machine. The surplus materia-l1 falling olf the upper belt is sufficient to dust the lowerbelt mak- 'ing an additional duster unnecessary ordinarily. I Y

`Having thus described my invention what I claim as new and desire to secure by' Letters Patent of the United States, is as folj lows, modiiic'ations within the scope of the claims bein expressly reserved:

1. A confectionery rolling machine comprising a frame having a fixed bed, an endless apron movable over the bed, a vertij cally adjustable frame carried by the first frame, a'second endless apron carried by the movable frame over the first apron, means to move the adjacent Surfaces of the two belts in the same direction at different 3 rates of speed, and means Vcarried by the adjustable frame to give the upper belt a horizontal circular movement 1n addition to its longitudinal travel.

2. A confectionery rolling, machine coml Y Y Aprising a frame having a fixed bed, an end- The machine is driven from a motor less apron movable over-the bed, a verticallyy adjustable frame carried by the first frame, a second endless apron carried by the movable frame` over the rst apron, 1 means to move the adjacent surfaces of the two beltsin the same direction at different .rates ofspeed,1means carried by the adjustable frame'to, give the upper belt a horizontalcircular movement in addition to its 1 longitudinal travel, means to feed lumps of material intermittently on the lower belt, andmeans to dust flour on the upper belt from which it is discharged to the lower ielt.
