- STAPLE FEEDING AND INSERTING DEVICE.

SPECIFICATION forming part of Letters Patent No. 746,967, dated December 15, 1903.

Application filed March 10, 1902. Serial No. 97,519. (No model.

To all whmn it may concern:

Be it known that we, ROBERT W. LEVIT'I and JACOB L. SHOUGH, citizens of the United States, residing at Somerset, in the county of 5 Perry and State of Ohio, have invented a certain new and useful Improvement in Staple Feeding and Inserting Devices, of which the following is a specification.

Our invention relates to the improvement IQ of staple feedingand inserting devices of that class in which staples are fed successively and automatically to a point where they receive the driving orinserting pressure; and the objects of our invention are to provide a simple 5 and effective feeding and inserting device of this class of improved construction and arrangement of parts, to provide improved means for loading or charging the feedingmagazine, to provide an improved construction and arrangement of driving or inserting plunger, and to produce other improvements, the details of construction of which will be more fully pointed out hereinafter. These objects we accomplish in the manner illustrated in the accompanying drawings, in'which Figure 1 is a side elevation of our improved feeding and driving device. Fig. 2 is a transverse section on line a: so of Fig. 1. Fig. 3 is a central vertical section on line 3 y of Fig.

2, and Fig. 4 isa view in elevation of one of the staples which may be used in connection with our device.

Similar numerals refer to throughout the several views.

'35 'In carrying out our invention we employa staple-containing or magazine body consisting of an inclined bar 1, the lower end por tion of which is curved or bent from the direction of the length of the bod y,as indicated. o This bar-body 1 has its front face and outer side cut away to form an angular recess 2,

which extends from a poi'ntin the upper end of said bar through the lower end thereof.

Within the recess thus formed is adapted to .5 be retained in the manner hereinafter described a correspondingly-shaped guide-bar 3, said guide-bar being su bstantially T- shape in cross-section and having its tongue portion 3 extending, as shown, within the recess ;o 2. This tongue portion is of such width as to result in the formation of a space, as shown similar parts more clearlyin Fig. 2, between the rear side of said tongue and the rear portion or back of the bar 1, and to further result in the outer face of said tongue portion being below the plane of the outer surface of said bar. The upper end of theguide-bar 3 at an outer point is pivoted, as indicated at 4, to an outwardlyextending arm 5 of the body 1. The guidebar is normally held in its place within the angular recess of the bar 1 through the medium of a suitable catch 6, arranged at the lower end of the guide-bar 3 and adapted to detachably engagethe back plate of the bar 1.

Theinturned lower-end portion of the magazine bar-body l is provided with oppositelylocated bearing extensions 7, within which is pivoted at the junction of its arms an angular lever 8, the lower and longer arm of which depends in front of the lower end of the tongue 3 of the guide-bar 3.

The magazine bar-body l is provided in its upper portion with a fixed laterally-extending arm 9, through a vertical openingin which passes loosely a vertical plunger-rod 10, this plunger-rod having a flattened blade-like termin-ation 11, which is adapted in the manner hereinafter described to be projected between the lower end of the guide-bar 3 and inner face of the lever 8. Surroundmg the rod 10, between the arm 9 and the upper side of the lower end portion of the magazine bar-body l, is a coiled spring 12,the lower end of the latter extending over onto and exerting a downward pressure on the upper and substantially horizontal arm of the lever 8. The upper end of the spring 12 engages the under side of a pin or suitable stop 13 of the plunger-rod 10, said spring normally holding said plunger-rod elevated and the pressure of the lower .end of the spring on the upper portion of the lever B normally retaining the lower arm of said lever in such slightly-inclined position as to cause it to abut against the lower end of the guide-bar 3.

In utilizing our invention the lower end of the guide-bar is swung outward, said bar swinging on the pivot at to a desirable position, after which staples, such as are indicated in Fig. 4 ofthe drawings, are arranged to I00 straddle or embrace the tongue portion 3 of said guide-bar. This being accomplished,

the lower end of the guide-bar is swung inward and latched through the medium of the catch 6 in its place in the recess 2 of the bar 1 and, in the position shown in the drawings. The staples being thus arranged on the guidebar, it is obvious that the lower staple will have dropped to a position immediately beneath the lower end of the blade termination 11 of the plunger 10, so that when a downward pressure is exerted on said plunger its blade portion 11 will serve to force the staple downward between the end of the guide-bar 3 and the adjacent face of the lower arm of the lever 8, the plunger thus serving to drive or insert the staple-points downward into the material into which it is intended to be driven or inserted. In its downward movement it is obvious-that the lower blade-like termination of the plunger 10 may either by contact with the inclined face of the lever B or by pressing the staple against said lever serve to force the lower arm of the latter outward to permit of the passage of the staple. It is obvious that when the downward pressure on the plunger is released the spring will return both the plunger and lever to their normal positions and that the next succeeding staple will have dropped into position for driving or insertion.

It is obvious that our improved staple feeding and driving device may be operated by driving the plunger-rod downward by hand or other power and that said plunger-rod may, if desired, be connected with any suitable or well-known means for imparting a downward movement thereto. It is also evident that the magazine may be suitably supported during the operation above described and that any desirable form of clenchingblock or other suitable receiving-block may be employed below the outlet of the staples.

It will readily be understood by the construction herein shown and described that simple and effective means are provided for rapidly charging the staple-holder or magazine with a comparatively large number of staples and that simple and desirable means are provided in conjunction therewith for successively discharging these staples with their points downward.

In case it should be deemed more desirable it is evident that the guide-bar might be pivoted at its lower end to the body 1 instead of the upper end thereof, as herein shown and described.

Having now fully described our invention, what we claim, and desire to secure by Letters Patent, is-

In a staple feeding and driving device, the combination with the inclined recessed bar 1 and a substantially T-shaped guide-bar pivotally connected with said bar 1 and adapted to have its tongue portion projected within the recess thereof, of a vertically-arranged spring-actuated plunger adapted to work as described in front of the lower inturned end of the bar 1 and a spring-actuated lever 8 normally pressed against the lower end of said guide-bar 3, substantially as specified.
