SHINGLE-MACHINE.

Specification of Letters Patent;

Patented Aug. 12, 1919.

To all whom it may concern:

Br it "nown that I, Go'rrrnm Humnuno, a citizen of the United States, residing at (3 929 Soiith Laflin street, Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Shingle-Machines, of which the following is a specification.

This invention relates to a shingle cutting machine. It relates more particularly to an. improvement by which the shingles, as they iLl'GZL'llll from a sheet of shingle-making material, are kept separate fromeach other and prevented from becoming mixed or trossed. The inter-mingling. which occurs without the use of this improvement causes difliculty in sorting and packing the individual shingles in neat, compact, and regularly arranged piles. v

The invention is applied to that class of shingle cutting machine in which a flexible sheet of shingle-formin material is slit longitudinally to form shingles of the proper width and is cut oil at regular intervals to form the shingles of proper length. Such machines have given trouble on account of the tendency the severed shingles have of falling across each other or the edges of the same overlapping and causing the shingles to become mixed or out of alinement with each other.

The invention will be understood by reference to the accompanying drawings in which:

Figure l is a plan view of the machine;

Fig. 2 is a side View of the same;

Fig. 3 is a side View showing a different position of the cutter; and

Fig. 4 is a perspective view of the cutter, showing the separating device thereon.

In the figures, reference character 1 represents a sheet of flexible material out of which shingles are made. This sheet is fed forward in the direction of the arrow by the usual means (not shown) along the bed 2 and under the slittiugdisks 3 mounted upon roller 4 and over the bed plate knife 5 where the sheet is cut transversely by the cutter 6.

The cutter 6 is mounted upon the revolving roller 7 which is driven by any convenient means such as gear wheel 8. Mounted upon the roller 7 is a sheet of metal 9 exi tending partly around the roller 7 and disposed at such a distance from the axis 10 is maintained between the outside surface of said sheet 9 and the bed plate knife 5 to permit the shingle sheet to pass therethrough as the roller 7 revolves. Upon the outside of the sheet 9 are a number of cirof rotation of roller 7 that suflicient space cumferen-tially disposed wires or strips of wires 11, divide the chute 13, down which the shingles slide, into a number of compartments. These plates 12 have their ends which are in proximity to the roller 7 cut away as shownat 14 so that the outside of the wires 11 on sheet 9 almost touch the same as the roller 7 revolves. 15 is a receptacle into which the severedzand sepa-- rated shingles fall.

The operation is as follows: The sheet 1 of shingle-making material of proper width is 'assed along the bed 2 under the cutting r0 ler 4: where it is slitted by means' of the slitting disks -3. Theslitted sheet then passes over the bed plate knife 5 until the proper length extends thereover when the knife 6 mounted upon the roller 7 descends and severs the sheet. As shown in Fig. 2, the slitted sheet 1 just'before being severed by knife 6 follows alon the outside of the sheet 9 and is guided tierebywith the wires 11 slightly separating the slitted ends so that they Wlll readily pass into the compartments formed by the plates 12 and be prevented from intermingling as they slide down the chute 13 into the receptacle -15. It will be noted that the slitted ends of the sheet 1 pass into the spaces between the plates 12 before the sheet is severed by the knife 6 so that it is impossible for the shingles to cross each other however rapid the cutting. operation may be. Because of the fact that the outside of the wires 11 almost touch the rounded edges 14 of plates 12, the space between the shingles when they are cut is practically closed. This makes it certain that the group of shingles will be maintained entirely separated from-each other and cause the shingles to be piled in the receptacle in as many regular and neat piles as there are slitted ends of the sheet.

Various changes may be made in the details without departing from the spirit and scope of the invention.

What I claim and desire to secure by Letters Patent is:

i 1. In a shingle cuttin machine, a slitter to divide a sheet of roofing material into a plurality of strips, a severing knife to out said strips transversely, and means to prevent shingles in transverse rows from intermingling after being severed.

2. In a shingle cuttin machine, a slitter to divide a sheet of roofing material into a 'plurality of strips, a severing knife to out ends before severing the same.

4c. In a device of the character-described,

means for slitting a shingle strip, means for severing the sllts and means for positively separatlng the slitted ends before severing.

volving guiding means associated with said knife, and separating means revolving with said guiding means.

'7. In a device of the class described, in combination a revolving knife, a circumferentially disposed sheet of metal having circumferential wires on the outside thereof revolving with said knife, vertical plates disposed substantially in the same planes as said wires, said plates being cut away in proximity to said sheet so that said wires pass along said cut away portion.

In testimony whereof I aflix my signature.

GOTTFRID HULTBERG.
