ROBERT ARDREY, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR OF ONE- 7 HALF TO WILLIAM TALBOT, OF SAME PLACE.

. PAPER-ROLL CUTTER OR EDGE-TRIMMER.

SPECIFICATION forming part of Letters Patent No. 273,24=4, dated March 6, 1883.

- Application fileddianuary 18, 1882. (No model.)

To all whom it may concern Be it known that I, ROBERT ARDREY, a subject of the Queen of Great Britain, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and. useful Improvements in Paper-Roll Cutters or Edge-Trimmers; and I do hereby declare the following to be a full, clear, and exact description of the invention, referto once being bad to the accompanying drawings, which form part of this specification, in which- Figure 1 represents a front elevation of my improvement 5 Fig. 2, a rear elevation, and Fig. 3 a side elevation, thereof; and Fig. 4. is

A a perspective of the adjustable bracket carrying center pin or stud.

My invention has for its object to provide an improved machine or device for trimming the edges of wall-paper while in the roll.

My invention consists in the peculiar construction and combination of parts comprising the machine or device hereinafter described and claimed, including a concave bearing or rest for the roll, a curved-edge knife for trim- 2 5 ming the ed ge-of said roll, a clamp for binding the roll whilebeing cut, and a centeringstud for maintaining the end of the roll exactly in the plane of movement of the knife, so as to secure a perfectly-straight cut.

Referring to the acccompanying drawings, A indicates the base-board or bed-plate, upon one end of which are secured parallel standards B B O O, the standards B B being united by or formed integral with an arch, D. The 3 5 standards 0 O are connected by a plate, E, upon which is secured a concave box, F, which forms a bearing or rest for one end of a roll of paper, X. If desired, said plate E and bearing F may be made in one piece. A cross- 0 head, G, is fitted between the standards'B (J, so that it may be moved vertically therein, as in guides. To this cross-head is secured a knife-blade, H,havingacurved cutting-edge, h. V

I represents a lever pivoted at t on the arch 4 5 D, and connected by a link, K, with the crosshead G, so that as the outer end of said lever is depressed the cross-head and its knife will be caused to descend.

L represents a lever pivoted on one side of the bearing F, and extending across the same,

projecting on the opposite side, as shown, beyond the standards B G. Said lever is pro- "ided with a spring-catch, M, which, when the lever is depressed, as shown in Fig. 2, engages with a lip or flange,f, on the edge of the bearing or box F, thus securely clamping or binding a roll of paper if placed within the latter.

N is a standard secured to a foot, N, adapted to rest upon the base A, and formed with a slot, '12, for the passage of*a set-screw, n, which enters through said slot to a hole in the base A, provided for its reception. The upper end of the standard N is formed or provided with a stud, n which projects toward the front of the machine, and should be ex- 6 actly in line with the middle of the box F. By means of the slotted foot-N and set-screw n the standard N, with its stud, may be moved to and from the front end of the machine and fastened securely in any adjusted position.

The operation is as follows: The knife being raised, as shown in Fig. 1, a roll of paper is laid with one end supported on the bearing F, the other end being supported by the stud M, which enters said end as a center-pin, the 7 5 edge to be trimmed projecting beyond the plate E and under the knife H. The lever L is now depressed until an engagement of the spring-catch M is effected, as shown in Fig. 2. The outer end of lever I is next depressed, causing the projecting edge of the roll of paper to be smoothly and evenly cut off or trimmed by the knife. The clamp L is necessary to prevent the paper roll from moving while being cut, and the centering-stud a is also essential in order to adjust and keep the roll perfectly straight. Said center-stud also serves to gage the extent of projection of the end or edge of the roll forward of the plate E,

r and thus regulates the amount which shall be cut off of said edge. As the standard N is movable, it may be adjusted to various-lengths of rolls upon which it'is desiredto operate with the knife H.

' Instead of making the foot of the bracket N 5 with a slot to permit its adjustment, the stud or center-pin n may be adjustable longitudi- In testimony that I claim the foregoing I I nally in the standard N. have hereunto set my hand this 14th day of 10 What I claimas my invention is as follows: January, 1882.

The comblnation of base A, standards B O, ROBT' ARDREY' 5 arch D, plate E, concave box F, cross-head G, knife H, and knife-actuating and clamping Utnesses: levers I L, respectively, substantially as shown S. J. VAN STAVOREN, and described. CHAS. F. VAN HORN. fi
