INVENTOR T 5 E T T UNITED STATES THOMAS V. JONES, OF DECATUR, ILLINOIS.

STAPLE- DRIVER.

SPECIFICATION forming part Of Letters Patent NO. 420,074, dated January 28, 1890.

Application filed J U118 7, 1889. Serial No. 313,418. (No model.)

To all whom it may concern:

Be it known that I, THOMAS V. J ONES, of the city of Decatur, county of Macon, and State of Illinois, have invented a certain new and useful Staple-Driver, of which the following is a specification.

It is the object of my invention to provide acheap,simple,and effectivestaple-driver that may be used advantageouslyin upholstering, putting down carpets and matting, trimming carriages, attaching Wire-cloth to window and door frames, and for other analogous and obvious purposes; and I attain my object in the manner hereinafter set forth.

In the drawings accompanying and forming a part of this specification, Figure l is a side view of my device. Fig. 2 is also a side View showing the stock in central vertical section and exposing the internal construction. Fig. 3 is a face view of the lower end of the stock with the staple-holder detached.

The stock a has the lower flattened portion 5, one side of which is nearly in line with the longitudinal center of the upper portion a. The driver-bolt c has the handle (1. It is adapted to move longitudinally in the stock, and it has the lateral projection. c, that moves in slot a of the stock. The driverbar g is secured to the driver-bolt by screw it, or in any suitable manner, and its lower end moves longitudinally in a recess in head 1). A metallic stript'rests in said recess back of the driver-bar, and it has a retaining projection i, that fits loosely in a hole in the head and prevents the strip from becoming displaced longitudinally while acting as a pivot therefor. A bow-spring 7c in the rear of the strip tends to press said strip against the driver-bar and against the opposing surfaceof staple-holder e. Set-screw Z provides means for regulating the tension of spring k. The staple-holder is somewhat oblique on its upper surface, and it has flange-plates e, as shown in Fig. 1, that are secured to headb by screws extending through the plates and into holes 0 0. (Seen in Fig. 3.) The guardfinger f is secured to the head in a similar manner, screws extending through plates f and into holes n n; but the plate f is preferably slotted to enable the finger to be adjusted with relation to the holder 6.

In operation the holder is supplied with staples, as seen at m in Fig. 2, a staple is forced by gravity against the strip t'and under the driver-bar, the bolt is forced downward to drive the staple, raised to admit another, and so the operation may be continued until the holder needs resupplying. As the strip i is forced closely against the driverbar, but one staple can be admitted at one time, and as the discharge-path of the staple is held normally closed by the lower end of the strip a staple cannot escape withoutbein g driven.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- The staple-driver comprising the stock, the driver-bolt carrying the driver-bar, the stapleholder secured to the stock, the guard-finger attached to the stock above the staple-holder, the strip held loosely in the stock and opposed to the inner surfaces of the driver-bar and staple-holder, and the spring to the rear of the strip, as set forth.

In testimony whereof I sign my name in .the presence of two subscribing witnesses.

THOS. V. JONES. Attest:
