Application filed January 2, 1895. Serial No. 533,562. (No model.)

To all whom, it may concern.-

Be it known that I, JAMES M. BRADY, a citizen of the United States, residing at the city chines for'lrimming Wall-Paper, &c., of which the following is a specification.

My invention has relation to a portable ma chine for trimming and rolling wall and other paper; and it relates more particularly to the construction and arrangement of the parts of The principal objects .of my invention are,

first, to provide a simple, durable and effective machine for trimming and rolling wall and other paper; second, to provide a machine for trimming and rolling wall and other paper having means for guiding the paper in the path of the cutter and for maintaining the latter in a good working condition; third, to provide a machine fortrimrning paper with a -holder adjustable lengthwise of the machine on a shaft or rod connected therewith; fourth, to provide a machine for trimming paper provided with a two part shaft and clamping device for engaging the paper and permitting of the rolling of the same in such manner as that said shaft may be readily released from the clamping device and the latter from the rolled paper; fifth, to provide a machine for trimming paper with a holder comprising two members adj ustably engaging a shaft or rod and provided with engaging pins for the ends of the roll of paper and the members of said holder provided with lugs adapted to contact with the base plate of the machine to maintain the same in required position; sixth,

to provide a machine for trimming paper having a beveled edge cutter revolving between rotatable guides or disks held under spring tension and said guides provided with an eccentric bearing in connection with the machine to compensate for wear and to insure perfect guidance of the paper in the path of the cutter and for maintaining the latter in a good working condition and a detachable and separable shaft adapted to form the paper into a roll and provided with means controlled by a gear-wheel having a pivotal operating handle for rotating said cutter and actuating the paper laying up shaft of the machine; and,

seventh, to provide a machine for trimming paper having a holder longitudinally adjustable on a shaft, a beveled cutter with a gear, a separable and detachable shaft with a gear and a removable two part spring clamping device, the said cutter and laying up shaft actuated by a gear-wheel provided with lugs, with certain of them pivotally engaging an operating handle and one of the others provided with a pin adapted to engage said handle to permit in one instance of a rotation of said large gear-wheel and in the other, when thrown out of engagement with said lugs to prevent rotation of said wheel.

My invention stated in general terms, consists of a machine for unrolling, trimming and rolling wall and other paper, constructed and arranged in substantially the manner hereinafter described and claimed.

The nature and general features of my invention will be more fully understood from the following description taken in connection with the accompanying drawings, forming part hereof, and in which Figure 1, is a perspective view of a ma chine embodying features of my invention. Fig. 2, is a top or plan view of the same.

Fig. 3, is a detached detail view of the parts8o' of the spring pressed revoluble guides for directing paper in the path of the cutter and for maintaining the latter ina good working condition and the same provided with an eccentric bearing for adjusting said guides from time to time to required position. Fig. 4, is a perspective view in broken sectlonof a portion of a revoluble shaft provided with a feed roll having a corrugated or ribbed periphery for frictionally engaging the paper and feeding the same to the cutter and away from the machine, the said view embody ng a modified form of paper feed to the cutter and of the trimmed paper from the same of my invention. Fig. 5, is a top or plan V ew of the parts of the machine illustrated in Flg. 3. Fig. 6, is a central sectional view through the rotary cutter and eccentric guides of the machine, showing the beveled edge of sand cutter in position between said guides; and Fig. 7, is a top or plan View of a portion of the machine of my invention, showing the roll of Fig. 5, in application thereto for feeding-the paper to the rotary cutter of the machine and for causing delivery also of the trimmed paper from the machine for laying up into a roll or other form, for subsequent use.

Referring to the drawings A, is an oblong base-plate preferably made in two parts a and a, and which are hinged together at a and on one of the members is provided a re-v tainer or clip a engaging a backstop or pin a", of the other member of the base plate A, as clearly illustrated in Fig. 1, of the drawings. At the left hand end of the folding base-plate A, is suitably secured a bracket B, provided with a projecting arm I), having a U-shaped slot 1), and the opposite end of the bracket B, is provided with a bearing having a tightening screw Z).

G, is a bracket suitably secured to the right hand end of the base plate A, and provided at one end with a U-shaped slot 0 and at the opposite end is provided a bearing 0'.

D, is a longitudinal shaft or rod engaging the bearings 11 and 0', one surface of which is flattened at d, for a purpose to be presently fully explained.

E, is a holder consisting of right and left hand memberseand e, having projectingpins c and 2 for engaging the respective ends of a roll of paper and provided with rear bearings c and 6 with tightening screws 6 and c and lugs e and a, forming holders or supports adapted to be brought into engagement with the top of the base plate A, for maintaining the respective members of the paper roll holder E, in required position, to permit of the ready winding off of paper in a manner to be presently fully explained.

e, is a revoluhle washer of rubber, pasteboard or other material applied to the pin 6 of the member e, of the holder E, to reduce friction on the end of the paper roll in the winding of the same and to insure also a more perfect delivery of the paper drawn into the path of a cutter for the severance thereby of a narrow strip or fillet, as hereinafter more fully explained.

In the U-shaped slots 1) and c, of the brackets B and G, is detachably mounted a rod or shaft F, consisting of two separable parts f andf, screwing together in the manner illustrated in Figs. 1 and 2, and at the right hand end of said rod or shaft is secured rigidly thereto a gear f which is adapted to mesh with alarge operating gear-whee1 G, suitably journaled to the bracket 0. In one face of the gear wheel G, are provided lugs g and g, to which by means of a pivot 9 is attached an operating arm 9 provided with a handle 9 and in operative position. The same with its handle is brought into engagement with the pin 9 of ohe of the lugs g and 9 formed with another part of the gear-wheel G. In the operative position of said arm 9 withits handle 9 as illustrated in Fig. 1, rotary motion is imparted to said gear-wheel G, which imparts like motion to the gear f and to a gear 72, rigidly mounted on a journal h, se-

cured to the bracket 0, and carrying a beveled edge circular cutter H.

I, is a disk provided with a rear flanged hub i, and surrounding the same is a ring or annulus I.

I is a curved spring finger plate, the tingers of which engage with one surface of the ring or annulus I, and this plate is provided with openings through which are inserted a series of screws 2' engaging the disk I. The central opening in the spring finger plate engages the flanged hub 2', of the disk I, as clearly illustrated in Fig. 2, of the drawings. The rotary cutter H, having a bevel edge on one surface about the periphery the reot, normally engages between the disk' I, and annulus l, as illustrated in Fig. 1, and the periphery of the annulus 1, is slightly beveled in an opposite direction to that of the bevel surface of the cutter H, so that a good working surface for the cutter may be presented to the paper to be severed in the travel of the same and by a clean shear out through the actuation of the gearsf and h, and wheel G, a narrow strip or fillet may be removed therefrom. The inoperative position of the arm g, with its handle g, is illustrated in dotted lines in Fig. 2,of the drawings, whereby rotation of the gear-wheel G, in such position is entirely prevented. The disk I, and the aunulus I, are helda proper distance apart for the engagement of the cutter H, between the same by means of the spring finger plate I 1 is an eccentric bearing and upon which the spring controlled annulus or ring and disk are mounted and which bearing is secured to the bracket 0, in such manner as thatthe said disk and its annulus constituting spring positioned guides for the rotary beveled edge cutter H, may be raised or lowered by loosening the screw i of said bearing, whereby a good working surface for the said cutter is always thereby insured.

J, is a semicircular clamping device provided at one end with depending lips orlngs jand j, adapted to engage the shaft or rod F, after one end ot'the paper K, has been wrapped by hand or otherwise around the same.

In Figs. 4 and 7, is illustrated a modified form of paper feed to the cutter and of the delivery of the same away from the machine, comprising a roll L, having a corrugated or ribbed periphery composed of rubber or other gritty matter or material Z, and which roll is mounted on the trimmed paper laying up revoluble shaft F. This roll L, is provided with a clamping or tightening device Z, extending through a tubular or other castingl secured to one end of the same. This roll is employed as a feed, when a narrow strip or fillet is to be removed from heavy wall or other paper, not susceptible of being easily formed into a roll.

A roll constructed and arranged as above described and as fullyillustrated in said Figs. 4 and 7, is well adapted not only to uniformly feed the paper to the cutter H, but also to prevent bunching, creasing or jamming thereof, during the cutting operation of the same;

and moreover, this rollis adapted to deliver the cut paper uniformly and smoothly away from the machine, whence it may be laid up in any preferred manner, for subsequent use.

The mode of operation of a machine for timming paper of my invention as hereinbefore described,is as follows: The roll of paper K, is mounted on the pins of the two members 6 and e, of the holder E, and then led forward in the path of the rotary annulus I, and its disk I, and against the'rotary cutter H, whence the operating handle of the gear-wheel G, is manipulated to impart rotary motion to the gearsf and h, which is continued until the paper is trimmed in sufficient quantity to per mit of the same being wound around the shaft F, and theapplication of the clamping device J, thereto with the lugs or lips j and j, of said device engaging said shaft F, when by a further manipulation of said operating handle of the gear-wheel G, the paper-can be fed from the holder E, uniformly to the cutter for removing a strip or fillet therefrom and then wound into a roll onto the clamped shaft F, until the entire roll of paper from the holder E, has been trimmed and wound upon said shaft F. The shaft F, with the clamped paper around the same may then be readily removed by lifting the shaft from the U-shaped slots of the brackets B and O; and the shaft drawn outward from the roll of trimmed paper K, and the clamping device J, by tilting the roll may be removed by hand from the roll of trimmed paper.

It may be here remarked, that is preferred to make the clamping device-J, in two hinged or jointed parts, and other partsof the machine separable and detachable, so that the machine can be quickly detached and carried in a satchel and quickly set up for use.

It will be manifestly obvious to those skilled in the art to which my invention appertains that as to minor details, modifications may be made, without departing from the spirit of my invention, and hence I do not wish to be understood as limiting myself to the precise construction and arrangement hereinbefore explained; but,

Having thus described the nature and objects of my invention, what I claim as new, and desire to secure by Letters Patent, is-
