-invented an Improvement in- Machines for Making and Setting Blind-Staples; and I 'do hereby declare-that the following taken in connection with the drawing which accompanies and forms part of this specification, is a description of the invention sufficient to enahle those skilled in the art to make and use it.

This invention relates to a new construe tion-0r organization of machines for forming and driving staples, the invention consisting in certain new parts and combinations of ing the invention.

Figure'l shows the mechanism in front ele- Fig. 2 is an end view of it. Fig. 3 is The other figures show details. s e A denotes the bed 'or frame, which, iu connection with an upright, b, supports themech anism'. O is a vertically adjustable table, upon which the slat or'rod to be stapled is placed, the lower edge resting onthis table, and the upper edge extending under ashonlder, d, the back of the slat being supported against a vertical face, a} The top of the' shoulder d and another shoulder, j, form ways in which travels a reciprocating slide, f, on

' the front and near the opposite ends of which are tivo plates, 9 h, in each of which is a ho]: izontal hole for the passage of the stapleforming wire 1', said wire entering the machine through a stationary eye-piece, k, andnpassn ing under a spring-stop, l, which permits the wire -t0 be drawn forward, but prevents its;

he. wire passes under a s pring-feedcr, 'm,

v on the slide f and as the slide moves forward this 'feede'r is cramped down upon the the guide-eyes beiug'tbrmed'in a plate','r,fastened upon the front ofthe upright I). The

inner face of the plate r, at its front end, is inclined, and 'the guide eyepleads out to such face. Over the inner face of the plate 4" is a cutting-edge, s, onjthe bottom of a verticallysliding bender-plate, t, the cutting-edge being the converse of the inner face of the plate 1, and so that, as it descends, it strikes the wire at the end of the eye 11, and clips it off, cutting iton an angle, and thereby pointing it.

Bef0re, or just as the cutter reaches the wire, (in the descent of the bender-plate t,) the bottbln of the plate strikes the wire over the top of the beak q.- The bottom of the bender-plate t has a vertical slot, u, of a width exceeding thethickness of the beak q;

and as the plate moves down it bends the op- *pcsitecuds ofthe wire over theb'ealr q, and

down against its sides, and, thereby forms the wire into a staple, the end of the wire' projecting beyond the beak being of the length to form one of the staple-legs, and the length of wire from the beak to the mouth of the eye}; being the same, and forming the other leg. .Fig. 9' is a section through the bender-plate t, near its'end, showing the slot u over the beak g. This slot is made near-the f end of the channel in the plate It, in which the driver b reciprocates; and this channel and slot together form spaces in the plate t for the legs of thesta'ple; This chanpel'in plate t is occupied hy'the driver I) as the staple is driven. v

When the staple is thus formed its two .points are just above the edge of the slat to be stapled, and thebottom of the bender- .plate descends against the slat and holds it. The vertical movement of the bender is effected; hgna lever, .21, one armbt'Mbich-extendsinto a-slot, .w, in the bender-plate,-and this lever is actuated by another lever, m,'a pin, :1 from one arm of which extends into a bent slot, z, in the lever 11.

After thefjlever arm a has efl'ected the movement of the bender-plate down'upon'the slat, the arm still'furtber descends, but with-, out imparting movement to the bender, and

strikes the head of a driver, b The bottom of the driver(which moves in the channel in the lower-end of which the staple is formed) B I mm is in line with the formed staple, and over the beak, and just before the lever drives down the driver I) an incline, c, at the lower end of a lever, d, is forced in between an arm, a, (from the end of which projects the beak q,)

' and the upright b, and presses said beak back from under the staple out of the path of movement of the driver, the upper arm of the leve'r d having a cam-slot, f into which projccts the pin y, the pinstriking one incline of v the slot as it moves down, and thereby causing the lower end of the lever to force back the beak. When the pin rises it strikes another incline of the slot, andthrows up the the lower arm 9 of the lever w, the forward movement'of this arm causing it to strike the plate h and move'the slide, and with it the wire, thismovement takingplace just after the same movementol' the lever on has efi'ected the rise of thecutter, bender, anddriver, and the forward movement of the beak leaving these parts in position to receive the advancing end of the wire: i 1

When the wire is being cut and formed by the descent 'of the upper armof lovers", the arm 9 moves back, striking the plate g, and

returns the carrier-slide to its normal position, the feederm yielding and allowing the plates 9 h to slip upon the wire, the stop I holding the wire stationary duri11g -the back movement of the carrier-plate.

.,.-'Fixed to the lever-arm s is a cutter-stock,- 'h', having at its bottom end two cutters, i, and just as the arm is completing its descent these cutters strike the opposite sides of the wire, cutting upon each side a nick, k, as seen at Fig. 5, 'the wire being subsequently cut off between the two nicks, so that a'nick is formed upon one end ,of one stapleiamd one end of another by each action of the cutters. The metal displaced in cutting each nick forms a barb, which helps to confine the staple to the slat. I I

When the slat-rod is to have the staple applied to it the able 0 is raised and fastcued in positi to enable the slat-rod to be properly supported and presented to the action of .the' staple-driy ing mechanism.

To feed the rod a, ocker-arln, l, maybe connected by a. link (m to the lower arm 9, and a projection/n, upon this arm in its forward movement strikes eaoflm series' of 'tcethmn'a:stri'worracli astened to them-on When the slats are being stapled, the linkis unjoluted' from the lever, and the rocker-' arm may then act as a presser to keep the slat up to the face 0, for which purpose it is provided with a spring, q, the stress of which throws the arm inward.

Fig. 4 in the drawing shows the bender-- plate at its highest position, with the mechanism adjacent thereto.

Figs. 6 and 7 are sectional views, one with the parts in the position shown in Fig. 1, and the other with the parts shown in Fig. 4.

' Figs. 8 and 9 are cross-sections of the bender-plate t and its ways, Fig. 8 being asection above the slot u, and Fig. 9 a section through the slot u.

Having thus fully described this improvement in machines for making and setting blind and other staples as of my invention, I claim- 1. In combination with the supporting-table 0, the sliding and feeding carrier plate f,
