JOHN TAMBERIIN, OF PHILADELPHIA,PENNSYLVANIIL ASSIGNOR TO THE GEORGE W. BIABON COMPANY, OF'PI-IILADELIHIA, PENNSYLVANIA, A CORPORATION OF PENNSYLVANIA.

SHEET-LINOLEUM DISINTEGRATOR.

Application filed November 2, 1920. Serial No. 421,278.

This invention is a machine designed primarilyV for disintegrating sheets of linoleum fromwhich shapes have been punched for making inlaid linoleum, but it will be understood that it is not limited to operation upon sheets of this character.

The invention is characterized by a revoluble member (as a cylinder) provided with projecting devices (as rearwardly bentfmgers) spaced along the axis of revolution; a set of downwardly projecting stationary devices (as fingers inclinedat a small angle to the vertical) spaced along said axis of revolution so as to be passed in alternating relation by the devices first named; a chute extending downwardly from the punching machine for carrying the sheets to be disintegrated over the devices second named where they are engaged in shearing relation by the revolving devices first named; stationary projecting devices or strippers spaced along vsaid axis of revolution in alternating relation to the devices rst named and adapted for disengaging the broken or disintegrated material ytherefrom and from the cylinder, and means comprising a. conveyer for carrying away the broken material. Y

This mechanism, in the preferred practice, is combined with mechanism through which sheets are fed and by which shapes are punched therefrom, as in the manufacture of inlaid linoleum, the shapes being removed from the sheets and the remainder being fed down the chute to the disintegrating mechanism.

The invention is embodied 1n the mechanism set out in the following description and the accompanying drawings in illustration thereof.

In the drawings, Fig. 1 is a sectional elevation of mechanism for feeding and punching linoleum sheets in combination with my improved means for dismtegratrng and removing the punched sheets; Fig. 2 is a part sectional plan view taken on the line 2-2x of Fig. 1, and Fig. 3 is an irregular sectional view taken On the line 3X-3X of Fig. 1.

1n the machine illustrated, the linoleum sheet 1 is moved intermittently, `over a perforated stripper plate 2 and beneath a template 3, between the block 4 having the dies 5 thereon and the head 6. The movements of the sheet are effected by known carrier mechanism comprising the endless belts 7 which pass over the

wheels

3, 9 and 10, the latter being driven by a sprocket wheel 11 fixed thereto, a sprocket chain 12 passing thereover, a sprocket wheel 13 over which the chain passes, a pinion 14 fixed to the wheel 13 and a spur wheel 15 which drives the wheel 14 and the carriage 15 having grippers 15a'and 15b for engaging the sheet.

The block 4 is elevated by the rotary cams 16 which are connected to operate together by the meshing spur wheels 17 and act on rollers 18 on the block. The plate 2 is caused, by the elevation of the block, to press the sheet lagainst the,4 template 3, and the template (carried by the bolts 19 movable in the frame 15') is carried thereby against the frame. The dies 5 punch the desired shapes lfrom the sheet by passing therethrough, forcing the shapes into the corresponding apertures in the templet. Thereupon the block 4 falls by gravity as the cams 16 are revolved further, the plat-e 2 stripping the perforated sheetfrom the dies 5 as they are withdrawn.

The punched section of the sheet 1 is fed down the steeply inclined chute 20 into a box 21 through its top aperture 21.

A bar 22, which is disposed across the aperture at the bottom of the chute, is provided with the spaced downwardly extending projections or fingers 23 inclined at a small angle to the vertical and over which be substantially parallel to the fingers 23V in passing them and shall act therewith in shearing relation, instead of pulling and tearing the sheet; theends of the revolving ngers acting in shearing `relation to the bar 22 as well as to the fingers 23.

A bar 26, supported in the box 21, has

fingers or strippers 27 fixed thereto in spaced relation so that the fingers 25 shall pass between them in alternating relation, the strippers detaching broken linoleum adhering to the cylinder 24 and the fingers ,25, Y

The disintegrated `linolenm,` which 'tells from the cylinder and the fingers 25, passes between the :traine members 2S and frills upon the chute 29, which delivers it,I Within the box, to `the travelling belt or conveyor 30, the hitter running through the aperture 2l in the side of the box.

The cylinder' 2l and the belt 30 are opel ated in unison from the journzilled shaft 31 having1 thereon the spur wheel 32 end the sprocket Whee 33. The Wheel `3Q drives n pinion 34 lixed to the cylinder 24. 'Whe sprocket Wheel 33 drives n chain 35 which puisses over a sprocket wheel 3G, the hltterbeingtixed to n journalled shaft 37 having lixed thereon a pulley 38 over which passes the belt 30.

Having described my invention, I claim:

1. In a machine ot' the character described, the combination of a sheet conveyor, e s1otted member to which :rsheet is delivered by seid conveyor`y and :i distintegrator comprising a revoluble member having lingers movable through the slots in said slotted member, said fingers being so shaped as to engage a sheet on the slotted member substantially at right angles to the surface thereof, said slotted member and revolnble member cooperating` to sheer the sheet Without substantial pull thereon longitudinally.

In a machine ot the character described, the combination ol a chute having e bnr adjacent the mouth thereof with spneed downwardly projectingr fingers thereon, ai revoluble member having lingers thereon movable between the lingers first named, seid revoluble tingers beingr bent reznwardly with relation to the direction oit their revolution and haring their sheet engaging parts substantially parallel to the lingers first .named in passingr them, e stripper having .fingers through which said reif olnble fingers pees, and` :i conveyor to which material disintegrated by snidfingers is discharged.
