combination and arrangement of parts hereinafter described and claimed and illus: trated in the accompanying drawings.

in the said drawings l igure l is a side elevation of stapling machine embodying improvements with one of the two shells 1 other fastening means passed three 11 the holes if, both parts of the casing beingprovided with. such holes the holes heing in ineinont when the two parts are peep ,placel. together. vfithin the'vertical A -forined by c gposiiig angular nav grooves in the frame parts-the driver B works. This driver is rectangular iii-cross section fitting the grooves of the. casing and is prevented from. having movement other than vertical by its rectangular form and the cones; ending form of. the way iii Which,

it works. It is held normally in its upper-. most position and returned to. such position after being depressed, by the compression spring C located between .ltS.tlIlOl) B and the of the casin 6n the rearv of the driver is a longitudinal recess B in which the lug D of the rocking piece D is located. and its lower extremity is formed.

into a staple-drivingcutter B which works in the vertical grooves A of the casing, formirn a restricted continuation of the way A". driver is checked at the proper point bv' the oulder formed at the junction oi A and contact of recess B x piece which brings the depending D of that member into contact with to stud extending through the casing, after rocking that member and giving the staple moving means forward movement.

The rocking member D is pivoted at D and. in addition to the projections 13' and D has a rearwardly depending portion D to which the staple feeder F is pivoted. In

e lip B at the lowerend of The downward movement. of the.

. and its upward movement is checked 1th the projection of the rockthis manner the feeder is retracted when the member D is rocked by the downward the path of the staples, and the longitudinal recess B of the driver is, therefore, of such length that the lip B does not come in contact with the projection D until this point in the upward movement of the driver has been reached. Nor should the lower end of the feeder be withdrawn from the staple strip until the end staple has been severed from the strip, and this is provided for by the downward free movement of the driver before it strikes the projection of the rocking piece D.

The feeder consists of the forked lower end or claw F, constituting the primary staple moving means, adapted to engage the staple strip G .between the staples, the forked upper end F by which it is pivoted to the part,D andi the intermediate portion F. It is pressed against the staple strip by the volute spring H which has its upper end held ina slit in the depending lug D, and its lower end constantly in contact with the feeder F immediately above the staple-engaging fork. The spring, therefore, on account of its construction and arrangement with respect to the parts D and F, and the arrangement of these parts, not only acts to press the feeder against the staple strip but has a tendency to return the member D to its normal position, and at the same time to thrust the feeder forward. In this manner, a limited forward pressure is exerted upon the staple strip the moment the driver begins to ascend which, of course, occurs instantly when the driver has driven the detached staple. This action is of great advantage in preventing the staple strip,

from becoming displaced and insuring the complete movement of a staple into the path of the driver.

The staple moving 'cl'aw F is withdrawn from behindthe staple, after the foremost staple has been severed, by the impact of the upper edge of the recess B against the projection D of the rocking piece D, thus causing that piece to. rock and draw the said claw upward and backward from contact with the staple.

The spring staple holder J consists of a strip with a lower beveled edge and a looped upper end J turned around the stud A to secure the'said holder. The holder is constantly pressed against the upper surface of the staple strip (see Figs. 1 and 2) by the pin A which holds it" constantly flexed so that a strong pressure is exerted by its lower end upon the strip of staples, and the staples thus held against accidental movement when not engaged by the feeder. This pin A also acts to cause the feeding member to move upwardly and thus disengage the strip when the strip is retracted in withdrawing it from the magazine.

The way A is of slightly greater horizontal diameter than the staples, and the width of the die or anvil piece K located therein is slightly less than the distance between the prongs of the staple so that the staple strip will be confined between the said die and the surrounding walls and will be guided and prevented from having vertical or lateral movement thereby. The staples are out 01f at the forward end of the die K when lower cutting end B .of the driver B strikes them, in the usual manner, and are carried down through the grooves A and forced into the material. In using thestapler to bind together thicknesses of relatively soft material it is desirable to first place the material on a metallic surface so that the ends of the staples will be upset or clenched by the said surface, and the machine may be provided with an anvil piece to be placed beneath the material, in the usual manner. In using it, however, for such purposes as the attachment of tags to boxes it is not necessary to provide such an anvil piece, and the prongs of the staple will be turned inwardly after passing through the softer material and while embedding themselves in the harder material. In order to facilitate this action the'point-s of the staple prongs are given a slight inward inclination, as shown in Fig. 3.

In operation, the machine is first supplied with a staple strip which is pushed forward until the outermost staple is in the path of the driver. The machine is then placed on the material to be stapled and the desired number of staples driven by striking the knob B and causing the driver to descend, a new staple being thrust into the path of the driver as soon as one is severed and driven, by the action of the feeder F, which on account of its construction and arrangement, moves upward and backward and thendownward and forward to its position behind each succeeding staple, as described.
