"Referring to the drawings, "Referring to the drawings, A represents a stationary anvil, A' represents a stationary anvil, which is secured to or which is secured to or formed with an arm rising formed with an arm rising from a suitable stand of convenient from a suitable stand of convenient form for use upon a form for use upon a writing-desk; and B represents writing-desk; and B represents a sliding guide-block a sliding guide-block fitted to the anvil A by a fitted to the anvil A' by a sliding joint, and having sliding joint, and having grooves C C, which match grooves C C, which match with the tongue of the anvil, with the tongue of the anvil, the upper face of the block the upper face of the block being flat. The normal position being flat. The normal position of the guide B is elevated, of the guide B is elevated, and, in order to keep it in this and, in order to keep it in this position, or from dropping position, or from dropping prematurely, I employ a prematurely, I employ a spring, D, which may press spring, D, which may press up under the guide, or a up under the guide, or a spring, D', which may press spring, D', which may press against it, and thus produce against it, and thus produce the necessary friction. E represents the necessary friction. E represents a reciprocating driver, a reciprocating driver, whose under face is flat, and whose under face is flat, and in the same is a concave recess, in the same is a concave recess, F, said driver having a F, said driver having a knob, G, for receiving the knob, G, for receiving the blows of the hand, and provided blows of the hand, and provided with a spring, H, for with a spring, H, for causing the return or elevation causing the return or elevation of the driver. of the driver.

"The operation is as follows: "The operation is as follows: A staple is placed within the A staple is placed within the grooves C C, with its crown grooves C C, with its crown resting on the anvil A, the resting on the anvil A', the points thus beingupward. points thus beingturned towardThe papers to be united arethe bending recess F. now placedupon the face ofThe papers to be united arethe guide B over the staple-points, now placedbeneath the driver, and, by a sharp blow and, by a sharp blow of the of the hand upon the knob G, hand upon the knob G, the the driver is forced downward driver is forced downward upon the papers.The guideupon the papers.

"In my original specificationI described the furtherseparate operation of completelyflattening down the ends ofthe staple thus bent over, by asecond blow between the upperand lower jaw of the implement,believing that the samewas new; but I have sincelearned that the same resultwas obtained by devices describedin previous letters-patentof the United States.Should the legs of the staple,when bent over by the sameblow which drives the same, asis hereinabove described, befound not to lie sufficientlyclose to the surface of the

paper, the same may be furtherflattened down by a second blowbetween flat surfaces in frontof the staple-channel and bendingrecess, respectively providedtherefor."Figs. 1, 2, and 3 show ahand-stamp embodying my invention,in which the driverreciprocates in a fixed head inthe manner of a plunger, whileFig. 5 shows the same inventionembodied in a hand-stamp, inwhich the driver is mountedat the end of a vibrating armpivoted at its rear extremityto the base, which rests uponthe table. It will be seen thatthe devices which constitute myinvention are to be found inboth these modifications, andthat both operate in preciselythe same manner, to insert bya blow upon the knob G of thehand-stamp, the staple throughlayers of stock to be united, andsimultaneously bend over theprojecting ends in the oppositebending recess provided therefor.
