Description

klJNITnD STATES PATENT unice@ JAMES C. MARSHALL, OF BOSTON, MASSACHUSETTS.
ROTARY CUTTER.
SPECIFICATION forming part of Letters Patent No. 235,163, dated December '7, 1880.
Application filed October 1B, 1880. (Model.)
To all whom Lt may concern Be it known that I, J AMEs C. MARSHALL, a citizen of the United States, resi/ding .at Boston, in the county of Suffolk and 'State of Massachusetts, have invented certain Improvements in Machines for Scoring and Cutting Paper for Boxes, &c., of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, making part of this specification, in Which-- Figure l is a perspective view of a paper scoring and cutting machine having my improvements applied thereto. Fig. 2 is a vertical section through the same; Fig. 3, sectional detail. Figs. 4 and 5 represent modifications of my invention.
My invention relates to certain improvements-in machines for scoring and cutting paper for boxes, &c., and particularly to the construction of the cutter-holders which carry the revolving disk-cutters and slide upon the stationary cutter-bar or carrier-shaft, arranged horizontally over the bed or table on which the paper rests; and my invention consists in a cutter-holder made in the form of a divided collar and adapted to be clasped tightly around the cutter-bar by means of a clamping screw or screws, in order that it may be readily adjusted thereon in any desired position for cutting or scoring the paper, whereby I am enabled to dispense with the adjusting mechanism heretofore applied to the cutter-holder, which necessitated the formation of a longitudinal groove or grooves in the cutter-bar, and also avoid the use of the set-screws hitherto employed in connection with the adjusting mechanism to clamp the holder when adjusted, which set-screws are objectionable, as they indent and mar the surface of the cutterbar, on which the holders slide, and often fail to hold the cutters immovably in position when adjusted.
In the said drawings, A represents the main roller, by means of which the paper to be scored or cut is moved over the bed or table.
B is the stationary cutter-bar or carriershaft, which is of circular form in cross-section, and secured, as usual, in a horizontal position immediately over the roll A, and at the desired distance therefrom.
C represents the cutter-holders, any desired number of which may be employed, these holders being mounted upon the cutter-har B, upon which they are adapted to slide longitudinally inV order that the revolving disk-cutters a may be set or adjusted at any desired distance apart. Each of these cutters a, which are of the usual form employed in machines of this description, is secured by means of a atheaded screw, b, to one side of the lower end, vv6, of its holder, instead of in a slit or between bifurcations thereon, as heretofore, for a purpose to be hereinafter explained.
Each cutter-holder O (shown in Figs. 1 and 2) is made in the form of a divided collar, being composed of two portions, c f, hinged or pivoted together at`g, which construction admits of the collar being readily opened to allow of its being placed upon the cutter-bar B or removed therefrom for repairs or other purpose without disturbing the bar or taking it off the machine, as is necessary where au ordinary cutter-holder is employed.
The upper ends of the portions ef, which abut against each other, are somewhat enlarged, as at 8, and through these enlargements passes a tangential clamping-screw, h, upon the square end of which is fitted a key or Wrench, by which the screw can be conveniently turned by hand to tighten or loosen it, as may be desired; and thus when an adjustment is required itis merely necessary to loosen the screw h and then turn the holder C upon the bar B to swing it up out of its operating position, or until the cutter a is brought into the desired position to score or cut the paper on the roll A, when, by a single turn of the screw h, the entire inner periphery of the collar C may be brought into contact with the surface of the bar B, andthe holder thus clasped tightly around it, all liability of slipping being avoided, as a much greater amount of friction is thus created than where an ordinary setscrew is employed, as heretofore, to clamp the collar in place upon the cutter-bar, While the indenting and marring of the surface of the cutter-bar by the point of this set-screw is also avoided.
A cutter-holder constructed to be opened as above described possesses another great advantage, inasmuch as it can be readily removed from the bar B and again placed there on in a reversed position, as seen on the lefthand side of Fig. 1, which, on account ofthe cutter being secured to the holder on the side of its lower end, instead of' between bifurcations thereon, enables two contiguous cutters t0 be brought much nearer together than has heretofore been possible in machines of this description, which is oftentimes a great convenience.
Furthermore, no complicated adjusting mechanism orlongitudinal groove or grooves in the cutter-bar B, which add materially to the cost of the machine, are required, while my improved cutter-holder is simple, cheap, and eilicient, and can be readily removed and replaced without taking the bar B oli' the machine and adjusted thereon in any desired position.
If desired, the cutter-holder maybe made of spring metal in a single piece with a dividing slit or opening, i, as seen in Fig. 4, and adapted to be drawn together and clasped tightly around the bar B by a single clamping-screw; or it can be made in two parts, secured together by two clam ping-screws adapted to draw the two parts together and cause them to tightly clasp the bar B, as seen in Fig. 5; but I prefer to use a holdetI of the construction shown in Figs. l and 2, for the reason that it can be more readily removed for repairs and reversed when desired.
The cutter-holders shown in Figs. 4 and 5 I regard, however, as mere 'modifications of the holder shown in Figs. 1 and 2, as they contain the principal features of my invention.
I am aware ot' the two United States Letters Patent Nos. 212,314 and 212,315 granted,
respectively, to G. L. Ingram and W. F. Lodge, February 1S, 1879, for paper scoring and cutting machines, and do not'l claim any of the mechanism therein described, as in both of' the machines described in the said patents the cutter-bar is grooved longitudinally and one or more set-screws are employed to clamp the cutter-holder upon the bar, which it is the object of my invention to avoid; but
What I claim as my invention, and desire to secure by Letters Patent, is- 1. In a machine for scoring and cutting paper, the combination, with the stationary cutter-bar B, of the adjustable cutter-holder C, made in the form ot' a divided collar, and pro vided with a clamping screw or screws adapted to draw the collar together and cause it to tightly' clasp or embrace the bar B to hold the cutter immovably ill position when adjusted, substantially as set forth.
2. In a machine for scoring and cutting paper, the combination, with the stationary' cutter-bar B, of the adjustable cutter-holder C, made in the form of a divided collar, and composed of two portions, ef, pivoted together at g, and provided with a tangential clampingscrew, h, adapted to draw the two portions e f together and cause them to tightly clasp or embrace the liar B to hold the cutter innnovably in position when adjusted, substantially as described.
Witness my hand this 2d day of October, A. D. 1880.
JAMES U. MARSHALL.
In presence of- P. E. TESCHEMACHER, W. J. CAMBRIDGE.
