ASBES TOS SHEET CUTTER.-

FILED JUNE 23 I921- To all who la it may concern ,1

Be it known that l,- Lonrs {lmso11, a

citizen of the United States, residing at N'cktown, in the county of Cambria, State of Pennsylvania, have invented certain new and useful improvements in Asbestos-Sheet Cutters; and 1 do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to new and useful improvements in cutting machines and parti ;-ularly to machines for cutting sheets of asbestos. a

One object of the invention is to provide a device of this character whichis simple in construction, easy and effective in operation, and. which light in weight, thus enabling the user to readily carry the same to a roof for the purpose of cutting asbestos shingles; 1

Another object is to provide a device of the character named having means for adjusting the cutting blades toward and away from each other.

, Another object is to provide means for supporting the asbestos sheet while being cut, and also means to catchthe'piece cut from the sheet.

Qther objects and advantages will be apparent from the following description when taken in connection with the accompanying drawing.

in thedrawing:

Figure 1 is a side elevation of a cutting machine made in. accordance with the invention, viewed from the higher table side thereof.

Figure 2 is a. side elevation viewflfrorn the opposite side of the machine.

Figure 3 is a vertical transverse central sectional view taken on the line 33 of v Figure 1.

Figure 4 is an end view of the'lnachine.

Referring particularly to the accompanying drawing, 10 represents a pair of uprights each having supporting feet 11. Secured to one vertical face of each'upright is a vertical elongated block 12, and also secured to the said faces of the uprights,

and extending therebetween, but belowthe' lower ends of the vertical blocks, is the stationary cutter blade 14. The blade 14 is tapered from the center toward its ends whereby to strengthen the blade. Secured asnnsrossrrsn'r cur-run:

strip 16, a pivot pin 17 being disposed cto the outer face of each end of the stationary blade 14 is a small. block 15, and disposed against the outer face ofeach of the blocks 15, and extending vertically in parallel relation to the block 12, is a guide through the upper endof each block 12, the

upright, and the upper end of the strip 16. On each of "these pivot pins is mounted a vertical swinging arm 18. The lower portion ofeach of the arms 18 is wider than the upper end, to permit the pivotally connecting thereto, of the short link 19.

Extending between the upper ems of the uprights is a connectingbar 20, and pivot-ally mounted on this bar is the angle lever 21. Pivotally connecting the upper end of one of the arms 18 withthe lower .end of the angle lever 21, is a link '22, and similarly connecting the upper end of the other arm 18 with the lever, above its pivotal mounting on the bar 20, is a second link 23. Secured to the outer face of the stationary blade 14,

and extending longitudinally thereof, ad-

jacent the upper edge of the blade, is a brace bar 24, and secured on. the upper face of the bar 24, and extending horizontally outward therefrom, is the table 25, on which the asbestos sheet is placed forcut ting, Secured to the lower portion of the other face of the blade 14, and in a plane below that of the table 25, is the receiving table 26,-for catching and supporting the piece out from the sheet.

nally over the blade 14 in position to cooperate with the upper edge of the blade 14,-

. v so The movable blade'27' extends longitudii no I pushed outwardly toward the ends of the machine, with the result that the arms 18' will be rocked on. their pivots and the blade 27 lifted above the blade 14, by. the short links 19. The asbestos sheet is placed on" the table 25 and slipped under the blade 27, to the proper distance, when the operator swings the lever 21 down, causing the blade 27 tocooperate with the blade 14, and sever the desired piece from the sheet.

The piece thus severed falls onto the lower able 2'6, as will be appzu'eni; from the drawing.

, What is claimed is:
