NITED STATES WILLIAM BRAIDWOOD, OF MOUNT VERNON, NEW YORK.
IMP ROVEM ENT IN MACHINES FOR PERFORATING PAPER.
Specification forming part of Letters Patent No. 170.337, dated November 23, 1875 application filed May 15, 1575.
To. all whom it may concern Be it known that I, WILLIAM BRAIDWOOD, of .MountVernon, in the county of Westchester and State ofNew York, have invented a certain new and useful Improvement in Machines for Perforating Paper and other materials, of which the following is a specification:
This invention is illustrated in the accompanying drawing, in which Figure 1 represents a plan view., Fig. 2 is a longitudinal section. Fig. 3 is a transverse section.
Similarletters indicate corresponding parts.
My invention relates to machines for cutting lines of perforations in paper and other ma terials, in order to facilitate-severing of the paper into parts of regular size.
My invention consists in a peculiar construe tion and arrangement of parts, wherebyI am enabled to perform the cutting of the perforations by the combined action of a hand-perforator, constructed among other things of a wheel-carriage, which supports a rotary cutting-tool, and of two parallel and stationary knives secured to a platform, and between which the cutting-tool is made to pass. The platform is provided with two or more rails, in order to form guides for the wheels of the perforator. With the guide-rails are combined cams, which cause the perforator to assumea higher position at the part of the rails at which the cams are located, and by this means the cutting-tool is brought out of contact with the paper to the extent of the length of the cams, and a portion of the paper remains unperforated.
The invention relates to certain other improvements, which are hereinafter described, and pointed out in the claims.
In the drawing, the letter Adesignates the platform of my machine, which is supported byuprights B, and which is divided by a longitudinal slit, (1, into two parts, on the parallel edges of which are secured the knives O O. The width of the slit a is such as to leave a space between the cutting-edges of the knives, or of the parts of the platform which in this case form the stock of the knives. The platform and the knives are rendered. adjustable by providing the platform with slots 1), through which pass its fastening-screws c. D designates a carriage. E E designate wheels, and
teeth resembling the letter M in outline. This.
wheel'F is intended to run in the space between the knives O O, and to this end the platform A is provided with guide-rails I, which are parallel to each other and to the knives. In the rails are formed grooves 01, which are adapted to receive flanges formed on the wheels E of the carriage. If the carriage is placed on the rails and moved to and fro, it is accurately guided, while a sheet of paper placed on the platform receives a line of perforations by the combined action of the cutting-tool F and of the knives Q C. The guide-rails I form the support for cams J, whose purpose is to raise the perforator, so. that it ceases in its action on the paper for a portion'of its length, and so that a portion of the paper remains unperforated. This-action is desirable as to paper intended for checks or drafts, and other like purposes, the unperforated portion of the paper servingto form the stubs of the checks.
The cams J embrace the sides and the top surface of the rails I, so that the grooves cl remain unobstructed. The cams are provided with slots 0, (see Fig. 2,) through which pass set-screws K, by means of which the cams are fastened to the rails, and by which, furthermore, the cams are rendered adjustable, so that the portion of the paper remaining unperforated admits of being gaged. The rails I I are supported on the platform A through the medium of screw-bolts L, which pass through the platform, and are provided with locking-nuts f. By loosening the nuts f the bolts can be raised or lowered to any desirable extent, and the movement of the bolts being imparted to the rails, they can thus be raised or lowered. The object of this arrangement is to admit of regulating the depth of cut of the perforator,
which partakes of an ad ustment of the rails, so that its tool F enters between the knives G O to a greater or less depth. Above the platform is situated a clamp, M, which has the form of a longitudinal strip, and is provided with a slit, 9, to admit of the passage of the cutting-tool F. To the respective ends of the clamp M are secured pins N, which project downward through the platform A, and are fastened to a beam, 0, which is connected tov a treadle. 1?, through the medium of alink, h.
The beam 0 is suspended from the platform by means of springs Q, Fig. 2, one end of which is secured to the beam, and the other end to the platform. The springs Q are so gaged that they hold the beam 0 and the ,treadle in such a position that the clamp N is held aloof fromthe platform in order to admit of sliding the sheet of paper to its proper position, while when the treadle is depressed the beam 0 and the clamp follow the action thereof, and the clamp exerts its functions, and the paper is tightly held in place while being perforated.
. In order to prevent jumping of the perforator from off the ends of the rails I I, I secure at that point stops It, which obstruct the movement of the perforator by catching the shaft H. The stops are secured to cross-pieces S, that form a connection for the ends of the rails I I, and which serve, to keep the rails parallel. The stops, however, may be secured to the platform.
The cutter F may be fast to the shaft H, and the rollers loose, or vice versa.
What I claim as new, and desire to secure by Letters Patent, is-
1. A hand-perforator, constructed of the carriage D, wheels E, cutting-tool F, handle G, and shaft H, in combinationwith the support ing-platform A and its parallel knives (J O, i
substantially as described."
2. In combination with thehand-perforator D E F GE, the clamp M, substantiallyas.
and for the purpose described.
3. The clamp M, having combination with thepins N attached at the ends of the clamp, the beam 0 carrying the pins and clamp, the treadle I, connected with said beam, and the springs Q arranged between the beam and the frame of the machine, substantially as and for the purpose described.
4. The hand cutting-tool or perforator, constructed of the carriageD, flanged wheels E, shaft H, and rotary cutter F, in combination with the vertically-adj ustable guide-rails I, con
structed to receive the flanges of theiwheelsi E, all substantially as and i'orthe purpose described.
5. Thecombination of the rotary perforator and the grooved guide-rails, having camsJ for elevating the said perforator to bring it out of contact with the paper, substantially as and for theobject specified. v
In testimony that I claim the foregoing, I have hereunto set my hand and seal.
