MECHANISMl FOR FORMING WIRE STAPLES AND SECURING THEM IN PAPER.

SPECIFICATION forming part of Letters Patent No. 225,933, dated March 30, 1880.

Application filed January 2S, 1880.

To all whom it may concern Be it known that I, CHARLES H. KELLOGG, of North Amherst, in the State of Massachu setts, have invented a new and useful Im 5 provement in Mechanism for Forming Wire Staples and Securing them in Paper or Card- Board; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanyio ing drawings, making a part of this specification, and to the letters of reference marked thereon.

The object of my invention is, rst, to guide the staple accurately into the holes made for it by the needles; and, second, to facilitate the fastening of the staple when it is in place; and to this end my invention consists, first, of the combination of two grooved needles, operating together, and moved by a plunger zo to pierce the paper or card-board; and it consists, second, ofthe combination of said grooved needles with two jaws and a former for forming the staples and guiding them into the holes made for them 5 and, third, of the combination z 5 of said grooved needles with a driver, movable guides, and an anvil for guiding` the staples, when formed, into the holes made for them, driving them fully into place and securing them irmly, all which will more fully 3o be hereinafter described.

Figure I is a side view of a frame containing l the needle-plunger, needles, driver, and the former for forming or bending the wire into staples. Fig. II is a front view of the same, with a piece of wire laid in position on the jaws, ready to be formed into a staple. Fig. III is a vertical longitudinal section of Fig. I at line D, showing the former in position between the jaws, and a staple formed. Fig.

4o IV is a vertical longitudinal section at line E of Fig. I, showing the needles moved up and the staple carried partially up to position with them. Fig. V is a side view, showing the former thrown or tilted back, and the staple carried up into placeby the driver, with its prongs against the outside of the guides. Fig. VI is a front view with the former removed, and showing the staple in'place and the movable guides moved apart, spreading the prongs of the staple outward, and the an- 5o vil moved down to clinch the staple. Fig. VII is a plan view of the jaws and former. Fig. VIII is a plan view of the jaws, needleplunger, and driver, the former being removed from its place; and Fig. IX is a plan view of the needle-plunger and the grooved needles.

In the drawings, A represents a frame in which are secured so as to move freely the needle-plunger B and the former 3, the latter having a longitudinal movement, and also 6o an outward or tilting movement into a position shown in Fig. V. The plunger B has two needles secured iirmly to its upper end, which are grooved on their inner or adjacent sides, as shown in Fig. IX, and the driver l is arranged with a longitudinal movement in the plunger B.

The jaws c at 6 are each grooved vertically on the inside, as shown in Figs. VII and VIII, the needles 2 moving up and down in said 7o grooves, and said jaws are also grooved horizontally at 7, as shown in Figs. V, VII, and VIII.

The guides 4 are secured at their upper ends to the head 9 in such manner that their lower 75 ends may move outward; and their lower ends are bent inward, so that both, when together, have approximately a wedge form, as shown in Figs. II, III, and IV, and an anvil,

5, is arranged to move down in the head 9, 8o said anvil, by its downward movement, forcing the two guides apart, as shown iu Fig. VI. These guides may be made of a springtemper, or elastic, and move inward again, by their own elasticity, when the anvil is moved 8 5 up again, or they may be moved in by any part of the machine with which it is connected, operating as a positive force to move them in after the anvil is moved up and out ofthe way.

The operation of my invention is as follows: 9o The mechanism consisting of the needle-plunger, with the needles and jaws, the driver, former, movable guides, and anvil, all occupying the relative position, each with the others, as herein shown, is connected with a machine by which the movements of each part are given by a cam or other suitable means.

The wire (iirst being cut into suitable lengths for forming into staples) is laid in its groove 7 on the ends of thejaws c, as shown in Figs. I and II. The former 3 (being in a positionjust above the jaws c) then descends between the 5 jaws, bending the straight wire 8 into the form of a staple, and carrying it down into a position between the jaws, as shown in Fig. III, and the prongs of the staple are l[hen in the grooves ofthe needles 2.

The needles, the former, and also the driver l then pass upward, the needles making two holes in the paper or the card-board, and the staple is also carried upward, with its'prongs in the grooves of the needles, which guide the prongs into the holes made for them. 'Ihe former 3 is then moved or tilted outward by the machine into a position shown in Fig. V, and the driver l is then forced upward, driving the staple entirely through the paper or card, the prongs passing up into a position with the lower ends of the guides 4 bet-Ween them. At the same time the needles are drawn down, and the anvil passes down, forcing the guides 4 apart, and bends the prongs of the staple outward, and the latter, being subj eeted to pressure between the driver l and the anvil 5, is clinched and secured, as shown in Fig. VI. The anvil then moves upward again, and the guides 4 and the former 3 pass back into the position shown in Figs. I and II, ready to form another staple.

In this manner the staples are formed automatically by this mechanism, and are also guided by the grooved needles 2 into the holes made for them in the paper or card, where they are rmly secured by the driver, guides, and anvil, as above described.

It is evident that the grooved needles may be used in any machine adapted to introduce small staples into paper, such as the binding of small pamphlets, 85o., with great advantage, and the jaws c furnish side supports for the grooved needles,`while they carry the staple up into the holes made for it.

Having thus described my invention, what I claim as new is- 1. The combination of two grooved needles, 2, operating' together, with the jaws c, for guiding a staple, when formed, into the holes made for it, substantially as described.

2. The combination of two grooved needles operating together, the jaws c, and a former, 3, for forming the staple and guiding it into place, substantially as described.

3. The combination of two grooved needles operating together, the driver l, the movable guides 4, and the anvil 5, for the purpose of guiding the staple into place and securing it there, substantially as set forth.
