PASTRY Application filed July 10,

This invention relates to machines for cutting sheets 'of plastic material into uniform fragments.

It is one object of the invention to provide a machine capable of shearing sheets of chewing gum, confectionery, dough, etc., rolled to a uniform, thickness into lozenges or diamonds of true and uniform rhomboidal shape. v

A further feature is in the provision of means. whereby such lozenges are formed with a double bevel'on each of. their several edges during the process of their manufacture and clean cut so that no ragged or rough surfaces appear. 1

Another aim is in the product-ion of a machine for accomplishing such purposes in the quantity production of goods, that is extremely simple and eflicient and under the instant control of an operator.

These and other minor objects are attained by the novel construction and combination of parts hereinafter described and shown in the accompanying drawings, forming a. material part of this disclosure, and in which Figure 1 is a top plan view of an embodin'ient'of the invention illustrating its application.

Figure 2 is a transverse sectional view taken on line 2-2 of Figure 1.

Figure 3 is a sectional View taken on line 33 of Figure 2.

Figure 1 is a rear end view of Figure 2.

Figure 5 is a. fragmentary transverse sectional view taken through the oblique cutting rolls.

Figure 6 is a fragmentary plan view of the dough sheet as it leaves the machine.

Figure 7 is an enlarged perspective view of one of the completed products.

The machine comprises a hollow bed frame 10 of rectangular profile, its longitudinal members having flanges 11 and 12, respectively at the front and rear, the latter being provided with an extension 13 at its forward, end and on the front side is an CUTTER.

1926. Serial No. 121,625.

open frame extension 14 these members to be supported by a bench or legs not shown. Supported by the main bed 10 are a plurality of channel shaped spacers 15 carrying a flat level platform 16. of considerable area, having at its rear edge a raised longitudinal rail 17. adapted to guide a sheet-18 of plastic material to be cut, this material having been rolled to a uniform thickness by means well known in the trade.

Bolted to the bed flanges .11 and 12 are a pair of doublepillow blocks 19, a similar pair of pillow blocks 20 being fixed on. the flange 11 and extension 13, in the same horizontal plane but at an oblique'angle to the first blocks.

Each pillow block carries two bearings 21, 21 and 22, 22, respectively upper and lower, the lower being seatedin the bottoms of the blocks and the upper supported by coiled compression springs; 23 disposed between the bearings, which are slidably mounted and adjusted by screws 24: in the pillow block caps 25,. v

- Revolubly mounted in the upper rear bearings 21 is a shaft 26, a similar shaft 27 being in the lower bearings, these shafts extending at right angles across the bed.

Another pair of shafts 28 are mounted in the bearings 21 of the forward angul'arly disposed blocks 20 as seen in Figure 1, oblique to the other shafts. v

Fixed on the shafts 26 and 27 are sleeves 29 and disposed-on the sleeves are fiat circular discs 30 having bevelled edges, these discs being held in rigid uniform spaced relation by spacing collars 31, the lower cutting discs extending through appropriate slotted openings 32 in the platfornr 16 to meet the peripheries of the upper discs in the manner of pairs of circular. shears.

Fixed on they forward, angular shafts 28 are similar sleeves 83 carrying a series of longitudinal segments 34:, having between their adjacent faces a series of straight, full length knives 35 provided with extending bevelled edges arranged in meeting relation,

at the center of the thickness of the sheet, the lower set of knives operating in a groove 36 in the platform 16.

This arrangement is best seen in Figure 5 and it will be noted that the peripheral surfaces of both series of segments 34 make contact with the material 18, as the shafts are revolved, tending to retain the sheet level and preventing its displacement by action of the cutters 35, which are timed to rotate in proper relation with advancement of the sheet.

It will also be noted that the bevelled'edges of the cutters 30 produce bevelled slits 18, as seen in Figure 3, while the bevelled edges of the knives 35, extending transversely across the slit sheet, produce correspond ingly bevelled edgeslS, as seen in Figure 5.

Fixed on the outer ends of the shafts 26 and 27 are spur gears 37 and 38 and the shafts 28 of the forward cutters are simi larly connected by spur gears 39.

Secured on the front end of the shaft 27 is a gear 40 and another like gear 41 is on the corresponding end of the lower angular shaft 28, both gears 40 and 41 being driven by an intermediate pinion 42 fixed on a shaft 43 mounted in bearings 44 carried on the front extension 14 of the bed frame.

A pulley 45, driven by a belt 46, is rotat ably mounted on the shaft '43 which can be driven by it upon engagement of a sliding friction clutch member 46.

The clutch is actuated by a handled lever 47 extending conveniently for an operator and pivoted to a bracket 48 carried by the rear member-of the extension 14.

The operation of the machine is believed clearly apparent from the foregoing, taken in connection with the drawings and it will be obvious that a sheet of suitable material may be cut to produce a multiplicity of parts, as seen in Figure 6, which upon separation will appear as in Figure 7, the angularity of each individual tablet being in con :lorinity with the angular relation of the front and rear cutter carrying rolls.

The foregoing disclosure is to be regarded as descriptive and illustrative only, and not as restrictive or limitative of the invention, of which obviously an embodiment may be constructed including many modifications without departing from the general scope herein indicated and denoted in the appended claims.

Having thus described our invention, what we claim as new and desire to secure by Letters Patent, is

l. A machine for cutting a plastic sheet into uniform rhomboidal tablets, comprising a platform over which the sheet is moved, a series of slitting cutters arranged above and below said platform the edges of said cutters meeting in a plane midway the thickness of the sheet, the axes of said cutters being at right angles to the path of the sheet, a second series of cutters disposed in the same horizontal planes as the first cutters and at an oblique angle thereto, and means for rotating all of said cutters simultaneously.
