HENRY I. BRUNNER. OF NAZARETH, PENNSYLVANIA.

MACHINE FOR EDGING- WALL-PAPER.

Specification of Letters Patent No. 14,803, dated February 26, 1856.

T0 all wiz/0m t may concern.'

Be it known that I, H. I. BRUNNER, of Nazareth, in the county of Northampton and State of Pennsylvania, have invented a new and Improved Machine for Trimming the Edges of Vall-Paper; and I do hereby declare that the following is a full and exact description thereof, reference beinghad to the accompanying drawings, making part of this specification, Figure l being a plan of the machine Fig. 2, a side elevation thereof; Fig. 8, a transverse vertical section of the same; Fig. 4, a perspective of a part detached.

Like letters designate corresponding parts in all the figures The frame, in which the parts are mounted, is composed of two end blocks A, A, connected by two bars B, B. A sliding carriage C, is provided with a groove in its lar or otherwise arranged so that the carriage may not turn on the bars. In the upper side of the carriage C, there is also another groove a, in which two blocks L, L,

' are allowed to move somewhat tightly, so

as to remain in any position where they are left. An arm N, extends upward from each block L, and curves over t-ill the upper end rests against a rod M, in the top of the' frame, without being attached thereto. At a suitable point in each of these two arms, is inserted a pivot cl, formed and situated substantially as represented in the drawings.

Their use is to hold the rolls of paperl to be trimmed, the edges of which are placed over them, as bearings.

With simple iixed 1 pivots, the paper will often become wedged thereon, and not readily unroll, or have its inner corners torn. To obviatethis I place washers, or caps c c upon the outside of the pivots so as to revolve easily about them. A i modification of this device would be to allow the pivots to freely turn in their sockets.

Through the frame C, passes a spindle S, having a suitable handle on the outer end for turning it; and on its inner end a pulley .i P, around which passes a cord b, the ends end pieces A A of rthe frame.

of which are respectively secured to the two By turning the spindle in either direction the carriage "f C will be moved in a corresponding direction and thus the roll of paper be adjusted to a proper position for trimming and its position varied if required during the operation.

The edges of the rolls are trimmed by means of two circular knives m, n, situated respectively on rollers E, F, so as to act together as shears, in the manner represented in the drawings. The rollers are just far enough apart to admit the thickness of the paper and draw it through by their own motion. To render their Operation more efficient, they may be covered with clot-h or other suitable elastic or yielding material. The lower roller F, is turned by Imeans of a winch G, on one end of its shaft, and the upper roller receives its motion therefrom by means of the friction of the paper passing between. The upper roller turns in bearings 0 (Fig. 3,) which are pressed down kept in close contact with that of the other knife n by means of a coiled spring p, or its equivalent, upon the end of its roller, as shown in the drawings.

The paper is again rolled up directly after being trimmed, by the following arrangement: A small angular winding rod T, is mounted in two projecting arms D, D. As one end, at least, of this rod is required to be set free in order to slip off each roll of paper after being trimmed, it is desirable to have a convenient device to allow it to be readily detached from, and then re-inserted in, its bearings. I accomplish this by allowing the arms D, D, to be separate sufliciently to withdraw one bearing of the rod; and causing these arms to be held together after the rod is again placed in its bearing, by a coiled spring g, or its equivalent, upon the projecting end of a rod R, passing from one arm to t-he other, as shown in Fig. l. The revolving motion of the winding rod is given by means of a band, or cord, z', passing around a pulley H, on the shaft of the roller E, and another pulley I, on the end of said rod. The relative sizes of these pulleys should be about the same as the relative diameters of the roller F, and the rod; and the varying diameter ofthe roll, as it increases, is provided for by having the band z', loose enough to slip on its pulleys as much as necessary.

The rst end of the paper is secured to the winding rod, by means of two collars f, f, which slide freely on the rod. At one angle of each is a pointed projection e (as seen most distinctly in Fig. et), which is easily slid over the corner of the paper and thus confines it. These collar clamps are readily moved away from the paper which is thus set free. One collar is slipped ofi' each time, before the roll of paper.

Sometimes paper is rolled up with the' wrong side out; and fine qualities often require both edges tobe trimmed. To accommodate these circumstances it is desirable to be able to pass the paper through the machine in either direction. My machine provides for this by having the projecting arms D, D, turn on the shaft of the lower roller F, so that they can be carried to eitherside of the machine without interfering with any motion thereof. Hooks It, h, are secured to the ends of the machine to hold the said arms in the proper position on either side. In connection with this arrangement of the arms D, D, the carriage C, is arranged so that it may be simply lifted from its bar B, and transferred to the bar on the other side of the machine.

The machine as above described, will trim a roll of paper in a few seconds, with a degree of accuracy and neat-ness unequaled by any other means in use.

I-Iaving thus fully described my improved machine for trimming the edges of wall pan per, I wish it to be understood, that I do not claim revolving shears, upon feeding rollers; but

Vhat I claim as my invention and desire to secure by Letters Patent is,

1. The bearing pivots el, CZ, with friction caps c c, supporting arms N, N, movable blocks L L, sliding carriage C, and adjusting device S, P, b, arranged and combined substantially in the manner and for the purposes herein set forth.

2. I also claim the sliding clamps f, f, constructed and operating substantially as herein set forth.

3. I also claim the combined arrangement of the rolling and unrolling devices, so that they may be quickly shifted from one side of the machine to the other, for the purposes specified.

The above specification of my new and improved machine for edging wall paper, signedy by me this twenty first day of December 1855.
