GAGE-STOP FOR PAPER-CUTTERS.

SPECIFICATION forming part of Letters Patent No. 247,785, dated October 4, 1881.

A pplication filed March 28,1881. (No model.)

To all whom it may concern:

Be it known that I, JAMES SNOVER, of H01- yoke, in the county of Hampden and State of Massachusetts, have invented a new and useful Improved Adjustable Gage-Stop for Paper- Outters, of which the following is a specification and description.

The object of my invention is to facilitate the adjustment of the gage of a paper-cutting machine in cutting or trimming paper to dif-' ferentsizes, and I accomplish this by the means hereinafter described, and illustrated in the accompanying drawings, in which- Figure I is a side view representing a papercutter having my invention applied thereto. Fig. II is a front view of the ordinary gagewheel of a paper-cutting machine having my invention applied. Fig. III is a side view of my adjustable gage-stop, with its lower face curved and adapted to be fitted to the ordinary gage-wheel. Fig. IV is a plan view of the same. Fig. V is a side view of my adjustable stop, having its face straight and adapted to be secured to a gage-rod. Fig. VI is a plan view of the same; and Fig. VII is a plan view of the gage-rod, slotted and adapted to have my adjustable stop secured thereto.

In the drawings, A denotes the frame of any ordinary paper-cutting machine; B, the bed; D, that part of the machine in which the knife operates; and E and E denote the ordinary gage-adjusting wheels, of which there are two, located substantially as shown in Fig. I, each having a bearing to revolve in journals either made upon or attached to the frame of the machine, and with a flexible metallic band passing around both wheels, a portion of which band, around the wheel at the front of the machine, isusually provided with a scale, as shown in Fig. II. v

The bed B of the machine is usually provided with a narrow vertical opening extending lengthwise the bed, through which extends a rod or bolt, 6, connecting the transverse gage 5 with the flexible band 3, as shown in Fig. I. In this manner it has been the practice for the operator to move the transverse gage 5 to and fro along the bed, in the direction of the flexible band 3, to any desired position, by turning the wheels E and E in either direction to bring any desired mark of subdivision of the scale on the flexible band opposite any permanent or stationary point, so that in trimming or cutting the paper the latter may be placed against the adjusted gage, that it may be cut to the required size. In adjusting the gage by means .of this scale it is obvious that no little care is required to adjust it to any degree of exactness, which is, of course, necessary in most cases, and much time is necessarily lost in accomplishing the desired end in this respect.

My invention obviates all this trouble and care on the part of the operator, and the gage may readily be properly adjusted for each out without even looking at the wheel or at the scale on the band, and with one simple quick movement of the hand. I may use the same wheels E and E, and the same flexible band 3, and when my invention is to be adapted and attached to the wheel E, I make two or more narrow openings or slots through the wheel in the direction of its depth, as shown at 14 in Fig. II, the ends of these openings being quite close to each other, as also shown in the same figure.

F denotes a shoe, which, when to be attached to the wheel,is curved upon one side,to fit approximately the periphery of the wheel, and is provided with a slot, as 0, through which extends a bolt, as 4, having its head fitted in a recess in the piece f, which is adapted to be moved along the outer face of the shoe, except when the shoe is securedin place. This shoe F is secured to the wheel by removing the nut on the bolt 4 and placing the curved face of the shoe against the periphery of the wheel at the desired point, and with the bolt 4 inserted through the narrow opening or slot 14 in the wheel, and then turning the nut upon the bolt at and against the inner side of the wheel. Another shoe and its piece f, exactly like the one described, is secured in the same manner at another desired point on the wheel; and in both these devices, which I denominate adj ustable gage-stops, the piece f may be adjusted upon the shoe F in securing it to the wheel, so that the end or shoulder 1 shall be in a position at any desired distance from the end or shoulder 2say one-quarter of an inch, more or less.

A dog or pawl, 12, is pivoted to any desired point on the frame of the machine, preferably so that its free and somewhat sharp end may fall ot'its own weight upon the periphery of the wheel E and rest there as said wheel is turned, so that as the latter is moved in the direction indicated by the arrow the end 2 of the shoe will strike against the end of the dog and the wheel will be stopped, and if the free end of the dog he moved outward over the end 2 a slight further movement ot'the wheel will bring the end 1. of the piecefagainst the dog and the wheel will be again stopped.

If the package of paper to be cut or trimmed to a size be laid upon the bed B with its rear edge against the gage 5, and the free end of the dog 12 against the shoulder l of the stop F, which is shown in the drawings just in front of the dog, the first cut is made down one side of the package, taking off the rough edges. The package is then turned with the trimmed edge placed against the gage 5, and the wheel E moved slightly until the end of the dog drops down against the shoulder 2 of said stop, which moves the guide a little forward, and the opposite edge of the package is trimmed, the package being thus cut to the required size in one direction-say as to its width. The dog 12 being raised, the wheel E is moved, the band 3 moving the gage 5 back along the bed of the machine until the dog is brought against the shoulder l of the other stop on the wheel E, and the package of paper being placed on the bed and against the gage 5, at right angles to its former position, one end of the package is trimmed; and the wheel and gage5 being again slightly moved, bringing the dog against the shoulder 2 of the same stop, the package is reversed in its position against the gage, and the other edge of the package is trimmed 0E and is cut to the required size.

The stops may quickly be adjusted to any desired position on the periphery of the wheel by simply loosening the thumb-nut on the bolt 4, moving the stop to the desired position, the piecef be moved independently to bring the shoulder 1 in the desired relative position with the shoulder 2, and the thumb-nut turned up against the inner face ofthe wheel, and the stop is thus firmly secured. Of course the movement of the wheel to bring the stop against the dog and the gage into the desired position on the bed requires no particular care after the stops are adjusted in the desired position on the wheel, and may be made very rapidly.

In some machines a bar is used hinged to the rear part of the machine and extending horizontally above the bed, toward the forward end of the machine, with a series of notches in thelower side of the bar, into any one of which the upper edge of the gage will engage when the baris dropped thereon, and the gage moved by means of the wheels E and E and band 3, an operating-lever being connected with the suspended notched bar, by which to raise and drop the latter in adjusting the gage in the desired position.

Instead of securing the adjustable stop F to the wheel E, as hereinbefore described, they may, with manifest advantage, be secured to a bar suspended horizontally over the machine in the direction of its length, in the same position in which the notched bar above described has heretofore been used, in which case I use a bar having a slot or narrow opening along its length, as l in Fig. VII, and I make the lower side of the shoe straight or flat, to fit the lower side of this bar, so that the stop may be moved along the bar and be secured thereto in any desired position in precisely the same manner that it is secured to the wheel E. The stops may thus be secured to the suspended rod on its lower side in relative positions to each other, as desired, substantially as shown in Fig. I, and in using the machine the rod 7, with these stops adjusted in the desired position, is raised by lifting the hand-lever 9, and the wheels E and band 3 are moved to bring the gage 5 in front of the foremost stop F on said rod. The latter is dropped upon the gage, and the wheel and band moved in the opposite direction, moving the gage back against the shoulder l of the stop, and the edge of the package of paper backed against the gage is trimmed, the gage moved forward and against the other shoulder 2 of the same stop, and the other edge trimmed. The rod is then raised, and the gage 5 moved back against the shoulder 1 of the other stop, the package of paper placed against the gage, and one end trimmed off, and the gage then being moved against the other shoulder 2 of the same stop, the opposite end is trimmed, the whole package being thus cut to the required size.

In using a bar or rod provided with notches, of course the latter, even when made as close together as possible, occupy considerable space, so that the guide cannot well be set with. a

firm hearing at points nearer together than from the side of one notch to the same side of the next notch. Consequently to provide for the adjustment of the gage at any and all desired distances apart different notched rods are required to be used.

By the application of my adjustable stops to a slotted rod, as above described, only one rod is required, inasmuch as the two shoulders l and 2 of each stop may be adjusted at any desired distance apart, and the stops them selves may also be adjusted at any desired distance from each other, so that any desired size of paper may be trimmed by the use of only one rod.

It is obvious that the wheels E and E and the band 3 may as well be placed in a horizontal position as in a vertical one, and it is also evident that the stops may be used with equal advantage, whether attached to the wheels or to the rod, and without departing in the least from the invention.

Having thus described my invention, what 1 claim as new is An adjustable stop for paper-cuttin g machines, consisting of the combination of a shoe, position of the gage in cutting paper to any as F, slotted through a portion of its length, desired size, substantially as described. as at c, a piece, as f, movable upon the outer face of said shoe, and with 'a bolt secured there- 5 in extending through the slot in said shoe, and Witnesses:

provided with a nut, whereby said stop may T. A. CURTIS, be adjusted to the machine to determine the CHAS. H. WOOD.
