TO ALL WHOM 1T MAY CONCERN:l A

Beit known that I, H, H. PEMBER, of the city, county, and Stn-tc of New Yorlr, hai'e invented a new and useful improved Machine for Cutting Canvas, Card-Board, etc. and I do hereby declare that the following is o. full, clear, and exact description thereot`,'which will enable others skilled in theart to malte and use the same, reference being had to the accompanying drawing, forming a part of this specification.

The present invention relates to a. new and useful machine for the cutting of canvas, card-board, and other sheet materials into strips, and the machine essentially consists of two feed or pressure-rollers, between which the canvas,etc'., to be-cut is1diawn, in combination with a. knife blade, so arranged that it can be'adjusted in position according t`o the width of strip desired, as wllbeherenafter explained.

Figure 1 is b. plan or top view ofthe machine; Aand Figure 2, 'a longitudinal vertical section taken in the plane of the line :v x, iig.' 1.

Similar-letters of reference indicate like pai-tagi A, in the drawings, represents the framework oi'lthe ymachine, which consists of two parallel upright side frames, B B, placed a. short distance apart, and braced by means of cross-bars or rounds, C C, at suitable points of the same. Between the two side frames B B, at one end of the same, are hung two pressure or feed-rollers, D D, one above the other, both of which rollers are connected together through gear-wheels E, at the corresponding ends ofthe same, to one of which a crank-handle, F, is fastened foi-convenience in turning it. G, a cross-bar hung so as to swing between the side frames B, in front of the feed-rollers D, and at the upper part of the said frames B. This bar is slotted in the direction ot`-its length, 'through which slot, H, passes a set or thumb-screw I, screwing into a holder-bar or plate,.K,uponv the under side of the bar Gr, carrying a knife 'or cutter blade, L, secured to a slotted stock or handle, M, through the slot N of which the said set-screw I passes, thi-s handle being on the upper side of the cross-bar G. The cross-bar in a direction across its width-is inclined, correspondingly incliuing the cutter-holder and cntterstock,so that with reference to the platform or table O, secured between 'the two side frames B, the cutter stands in a vertical inclined position, with the point of the knifeV or cutter projecting'throngh a slot, P, extending in the direction of the length of the said table To and along'this table O, at one side, is a guidepiece or bar, O, and at its 'front-end, R, is a cross-bar or rail, S,

between which and the top of the platform-a space or opening, T, is left.

In the use of the machine above explained, the cutter is first adjusted to the widAt-h'of strip which it is desired to cut the canvas, card-board, etc., by slidingy it along upon the slotted bar G, either away' from or toward the guide-piece .0, when, securing it-by tightening the set-screw I, the cnnvas,etc., is then run or drawn through the space T, under the cross-rail S, between it and the platform, to the knife, and from thence to and betweenv the pressure or feed-rollers D, by which, as they revolve, the canvas is then drawn forward to the action of the knife, and by it cut in aline corresponding therewith, care being taken to keep the edge of the canvas b against and in contact' with the guide-piece O. I claim as newand desire to secure by Letters Patent--d The combination of the feed-rollers D, teble or platform-0, haviugguide-bar Q, and cutter lor knife blade L, susceptible of adjustment, when all arranged and combined together, substantially as and for thepu'rpose described.

'Ille above specification of my invention signed by ine this l/eith clay of July, 1866.
