'TO ALL WHOM'IT MAY CONGERN:

Be it known that I, ELIJAH FJDUNAWAY, of Indianapolis, county of Marion, and State of Indiana, have invented new and useful improvements in Machine for Wiring Blind-Rods and Sla-ts; and'I do hereby declare 'the following to be a clear and exact description thereof, reference being had to the accompanying drawings,

:and tothe letters of reference marked thereon, making a part of this specification, in which- Figure 1 represents a top vieu' of ,thc machine.

Figure 2,1m end elevation.

Figure 3, a back view.

Figure 4, the slide and set-screw.

Figure 5, an end view of the slide and set-screw.

Figure 6, a view of the plates and eye in which the driver operates.

Figure 7, an end View of said plates and eye.

The nature of my invention consists in an adjustable eye, formed of steel plates, 'that the staples pass through, to be adjusted foi-wide or narrow staples, and of hardened steel, so as not to wear; also, the leather cord ,and pulley, as arranged and attached to both levers. A

A the frame or bed-plate; B the upright stationary post, in which themain` .leverC and staple-driver D operate; E the incline blade or bearer, upon which the staples are placed, and slide down to where they come in contact with the driver D that presses them down into the slat or rod beneath. His a sliding notched rod, moved by the action of the spring-lever J, and gives the regular and exact distahcesfor each staple to be driven .down into the slat or rod as it passes under the driver D. The slide K and set-screw L are used to centre the slats. The spring N holds the notched rod H to its'place. P, the upright post, (with a spring beneath,) to which the main lever C is,pivoted. -The slide Q is regulated by set-screws, R, and so adjustable to be moved back and forth to centre the staple in thick o1' thin slats or rods. At the one side of post Bis a pulley, S, .against which a leather round strap, T, operates, the strap or cord T being connected by a hook and eye to the lever C, and by another hook and eye to 'the spring-lever J; the cord drawing the lever `J forward, and the :spiral spring U forcing it back again; the spring being attached to a short upright post, V, to the top of which the lever J is pivoted. `The Vdriver D operates in a groove in the lower end of a plate on the post B. The lower en d of the brass or metal plate has a box or eye, W, (as seen at figs. 6 and 7,) with steel plates, X, that are adjustable, closer together or drawn apart to suit wide or narrow staples, the steel plates also preventing :the wearing ofthe eye on either side, and .are adjustedto either side by a slot and adjustable screw, Y.

When the machine is to be operated, 'the wire staples are placed on-the top edge of the incline bearer E. v One after another slides down it to the groove under the driver D. The lever C is then raised, and, with it the cordl drawing the lever J forward against a notch" on the rod H, pushing the rod, with the slat Z behind it onkel/ notch forward immediately under the eye W and the staple that is ready for the driver. The lever C is then pressed Adownmpon the staple, forcing it through the' eye into the slat each time, at equi-distances apart, as the lever J 'liesbackl to its place, ready to press against another notch in the top of rodl H. The backward and forward movement of the'lever .J is also regulated, and prevented from moving too far forward or back by adjustable projecting pins, a, on each side, adjusted byy slot and set-screw Z.

I What I claim as my invention, and desire to secure by Letters Patent, is-

The arrangement of the cord T with the levers Gand J, and pulley S, as herein described and for the purposes set forth` ELIJAH F. DUNAWA-Y.
