MILTON BRADLEY, OF SPRINGFIELD, MASSACHUSETTS.

LABEL- SPECIFICATION forming part of Letters CUTTER.

Patent No. 272,202, dated February 13, 1883.

Application filed May 2, 1882. (No model.)

To all whom it may concern Be it known that I, MILTON BRADLEY, a citizen of the United States, residing at Springfield, in the county of Hampden and State of Massachusetts, have invented new and useful Improvements in Label-Gutters, of which the following is a specification.

This invention relates to improvements in label-cutters,vand has relation more particularly to the construction in this class of papercutters of an improved binder to press upon the paper near the knife, of an automatic gage, and of devices for holding and moving the paper, the object being to provide improved devices for attaching a paper-binder to a machine of this class, which is adapted to move parallel with the knife and bed and to adjust itself, so as to bear with proper force upon the paper near the knife and quite across its sur-' face; to provide a gage which is automatically moved to and from a proper position behind the knife, and a label-clamp to retain a series of paper-sheets of small dimension in a level position upon the bed of the machine.

In the drawings forming part of this specification, Figure -I is an end elevation, partly in section, of a label-cutter embodying my invention. Fig. II is a side elevation, partly in section, of said machine. Fig. III is a side elevation of the label-clamp and a section of the bed of the machine. Fig. IV is a section of the gage-shaft and its directly-connected rotating connections. Fig. V is a plan view of the central portion of the bed and thelabelclamp thereon.

The operating parts of this machine aresupported upon the frame A,of cast-iron, to which are bolted or otherwise suitably secured the legs B. The said frame has cast upon each side thereof the vertical knife-frame-supports 0, each having a corresponding vertical slot, within which the knife-frame d is fitted and adapted to slide.

The bed D is made preferably of hard wood, and is provided with a series of'longitu'dinal grooves, 0 in which the back gage and the label-clamp are guided in their movements toward the knife. Said bed is secured on frame A by suitable screws and rests .upon transverse blocks 42.

The knife-frame d has its opposite faces properly finished, and has parallel vertical bearings therefor.

Aseries of adjusting or gib screws, 2 2 2, is placed in said supports 0 0, each side of the slots therein. The knife-frame is fixed in a proper vertical position between the edges of said slots, and a suitable .gib-strip is placed on each side of said frame, and the screws 2 being turned against the rear face of said knife-frame on opposite sides thereof, and said frame is thereby held in a proper vertical po sition in said supports 0.

The ends of the knife-frame d extend outwardly beyond the sides of the supports 0 c, and, have attached thereto by suit-able pivotbolts the ends of the connecting-rods a Two shalt'supports, h h, are provided on the under side of the fra'meA,in which are formed suitableboxes,in which to hang the transverse rock-shaft a. In each end of said shaft, which extends outwardly beyond the sides of said frame, is placed a pivot'bolt in a position to rotate eccentrically to the axis of said shaft a, and whereby the two connecting-rods c a are connected with said shaft. i

A lever-handle,f, is secured on one end of shaft to, by which the latter is rocked, and whereby the knife-frame is given a reciprocatin g vertical motion.

Au arm, a", is provided on shaft a, to which is pivoted oneend of a spring supporting-rod, c and the opposite end of the latter passes through the end of frame A under the bed D.

A spring, 50, is placed on rod 0 between a shoulder on said rod, near arm of, and frame A. When shaft on is rocked to operate the knifeswings up a little above the axial line of shaft or, when the force of said spring acts to assist the rotating movement of said shaft, and this last-named action of spring occurs at the time when the resistance to the descent of the knife through the pile of paper is the greatest, and thus aids rather than otherwise in carrying the knife down, and when the handle-lever fis swung back to lift the knife-frame, bringin g the parts to the positions shown in Fig.2, said spring 50 operates to hold the knife-frame and said handle in those positions.

A self-adj usting paper-binder, e, is hung on strips, the latter are held firmly against theframe, spring 50 is compressed until arm a ICO jections on said frame, as shown.

the front face of the knife-frame d to two vertical posts, 6 which are supported and guided so that they,with sa d binder, may have a free vertical movement in suitable perforated pro- The said posts 0 are connected to the slotted arms of two evener-levers. 8 8, which are pivoted on the face of said knife-tratne, and are provided each with an upright arm, to or between the upper ends of which is connected a spring. 9. Said evener-levers are pivoted together at the point 15 of their intersection by a pin fixed in one. of them, which passes through an oblong slot in the other one, and screws or pins fixed in posts a pass through longitudinal slots in the said evener-arins, as shown in Fig. 1.

Stop-pins are fixed in posts 6 to arrest the latter at a proper point in their downward movement, or to let the under side of the binder e, when at rest, stand about on a line with the edge of the knife (I.

The action of spring 9 and the evener-levers upon the binder e is to cause the latter, as the knife-frame and knife move down, (the latter against a pile of paper to cut it,) to press steadily and firmly upon said paper close by the edge of the knife, and to prevent any of the sheets composing said pile of paper from being drawn by the action ofthe knife, whereby imperlect work would be done.

It \\'Ill be seen that said binderc and its above-described connections move down with the knife-frame until said binder strikes the pile of paper 00, placed under the knifed to be cut, when the motion of the binder is arrested, except so far as it may be forced by the action of spring 9, and the frame d and knife dcontinue to move down until the latter shall have passed quite through said paper, the lower edge of that part of frame (1 beyond supportsc c then striking the ends of the stop-screws 7 7 and stopping the motion of said frame. The binder econtinues to hold the paper firmly in place until the knife (I shall be lifted quite away from it.

The evener-levers S, as constructed and applied to the knife-frame and connected to the posts e compel the binder c to move down, with its under side always parallel to the face of the bed 1) anti with the edge of the knife, whether the thing to be out be placed centrally between the ends of said hinder or not.

The rear edge of the bindere is beveled off, as shown in Fig. 2, to afiord facilities for looking down between said binder and the adjoining face of the knife, so that the paper can be accurately adjusted to a propercntting-line, if need be, otherwise than by depending solely upon a gage.

A gage, 71, adapted to restin the rear of the knife d and form a stop against which the end of a pile of labels or of paper may be placed to determine their width when out, is supported adjustably on agage-rod, 2' so thatit maybe moved toward and from said knife.

The downhanging end of said gage n is slightly below the surface of bed D, and has an oscillating movement in a groove, 0 back of knife d. Thus the lower sheet of a pile of paper, as well as those above it, strikes said gage when adjusted beneath the knife. Said gage-rod i is adjnstably secured in the end of the gage-arm i by a thumb-nut,o, and aspring, 12 the latter operating between a pin in said rod and said arm. Said gage-arm is secured on 'a transverse rock-shaft, m. (see Fig. 1,) which is hung on the rear side ofthe supports 0 c and back of the kni e-frame. and a short horizontal arm, '1 on said gage-arm strikes the rear side of the knife-fra me when arm i is in the position shown in Fig. 1, and there causes it to he held.

A short rack, c, is fixed on one end offramc d, and a pinion. a, hung on the end of shaft m, engages with the teeth of said rack. Said pinion i is adapted to have a limited free motion on shaft m, as follows: Pinion i is provided with a hollow hub, tKFig. 4, havingone of its sides cut away for about half of its length.

A pin, t. is fixed in shaft to in such position that one lip of the hub it will strike it wh n pinion iis turned in such a direction as will operate shaft at, so as to swing arm 2' in the direction indicated by the arrow in Fig. 2, and a coiled spring, 2, is placed on shaftm, one end of which engages with a pin in said shaft, and its opposite end engages with the lip of hub t opposite the one which,as above described, strikcs pin t.

The above-described construction of the pinion 11 and its connection with shaft m by the said pins and spring 2 are for the purpose of allowing a certain movement to frame at without turning shaft m, and whereby, when the knife-frame is approaching its highest point and the end of arm you arm 1' is restingagainst said frame, pinion imay rotate slightly against the tension of spring 2 and cause the gage a to beheld firmlyin position bytheforce of said spring; and, furthermore, said corn struction provides for allowing the frame d and knife 01 to descend and the latter to begin to out the paper before pinion t has rotated against pin t and commenced to turn shaft m and to lift up arm 71 and swing gage 12. away front the knife and the end of the pile w of paper, thus holding the latter in position until the binder e and the knife have control thereof. Said gage is adjustable on rod i for general dimensions; but when it is desired to adjust the gage so that cutting may be done very accurately said gage is adjusted finally by the aid of the screw 0 and the spring id.

The clamp H is especially constructed for use with this machine, and consists of an upperandlower plate, hinged together, asshown, one end of the upper one being provided with a thumb-screw, whereby the opposite ends of said plates are caused to approach each other and clamp a series of sheets of paper and hold them while being out. On the .lower one of work which does not elevate oneend of the pile, as is usual, above the face of the bed, thus keeping the paper in the best position to insure the best work. In using said clamp the paper a is secured in it, and,placing the block 5 in one of said grooves in bed D, the paper is pushed along under knife (I and against the gage a.

A back gage, n is provided for pushing for ward paper, having likewise guide-blocks w thereunder to follow in 'saidgrooves e in bed I D, and thus compel its edge next to the paper 00 (see Fig. II) to stand parallel with the knife, and consequently serve to forward the paper-pile to a true position under the latter, so that it may be properly out.
