staple-legs come up through the papers into the recess F, where they are bent over preparatory to the final olinching. The hand is now released from the knob of the driver, the latter then rising, and the papers are drawn somewhat forward, until the staplecrown rests upon the face of the guide B, when another blow is imparted to the driver, and the flat portion of its face descends forcibly on the staple-legs, so as to bend the latter close to the paper, thus completing the operation. It will be seen that the grooves C C serve to support and guide the staple-legs during their penetration through the papers, and the recess F is so shaped that, as the staple-legs enter thereinto, they will strike the concave or slanting walls of said recess, and thus be bent inward toward each other suficiently to insure their being bent down' properly when again struck between the faces of the guide B and driver E. A plate, g, may be advantageously employed to overlap the staple-crown for preventing the latter from binding while the legs are being forced through the papers. the recess F, where they are bent over by the slanting ends thereof. It will be seen that the grooves C C serve to support and guide the staple-legs during their penetration through the papers, and the recess F is so shaped that as the staple-legs enter thereinto they will strike the concave or slanting wells of said recess, and thus be bent inward toward each other, as shown in Figs. 2 and 3. A plate, a, may be advantageously employed to overlap the staple-crown, for preventing the latter from bending while the legs are being forced through the papers. It will be seen that the staple-support or anvil A', with the slotted or recessed hammer, operates to insert a staple through layers of stock to be united, and simultaneously bends over its projecting ends. In my original specification I described the further separate operation of completely flattening down the ends of the staple thus bent over by a second blow between the upper and lower jaw of the implement, 'believing that the same was new; but I have since learned that the same result was obtained by devices described in previous Letters Patent of the United States. Should the legs of the staple, when bent over by the same blow which drives the same, as is hereinabove described, be found not to lie sufficiently close to the surfaces of the paper, the same may be further flattened down by a second blow between flat surfaces in front of the staple-channel and bending-recess respectively provided therefor. Figs. 1, 2, and 3 show a hand-stamp embodying my invention, in which the driver reciprocates in a fixed head in the manner of a plunger, while Fig. 5 shows the same invention embodied in a hand-stamp, in which the driver is mounted at the end of a vibrating arm pivoted at its rear extremity to the base, Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is— 1. The reciprocating driver E, constructed with a flat face recessed, substantially as described, whereby the projecting ends of staples may be first bent over by entering therecess and then flattened down by pressure from face. 2. The self-adjusting guide-block B, having staple-guiding grooves C C and a flat face, upon which to complete the clinching of the staple, substantially as and for the purpose set forth. 3. The combination of the stationary staple support or anvil d with the sliding guide B, grooved to partially embrace and guide the staple-legs, substantially as and for the purpose set forth, 4. The combination of the stationary staple support or anvil A with the reciprocating slotted or recessed hammer, operating to insert a staple through layers of stock to be united and simultaneously to bend over its projecting ends, substantially as and for the purpose set forth. which rests upon the table. It will be seen that the devices which constitute my invention are to be found in both ́these modifications, and that both operate in precisely the same manner to insert by a blow upon the knob G of the hand-stamp the staple through layers of stook to be united, and simultaneously bond over the projecting ends in the opposite bending-recess provided therefor. Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is 1. The combination of the stationary staple support or anvil A′ and the sliding stapleguide B with the reciprocating slotted or recessed hammer operating to insert a staple through layers of stock to be united, and simultaneously bend over its projecting ends, substantially as and for the purpose set forth. 2. In a device for inserting metallio. staples, the combination of the staple-guide B, anvil A', spring D, and reciprocating driver, provided with the knob G, the whole arranged to operate substantially as and for the purpose set forth. 3. A staple-inserting implement having two opposite jaws arranged with relation to each other, substantially as shown, one of which is provided with a recess, the other with a vertically obanneled staple-guide, an anvil, and a spring, so that when the jaws are separated after driving a staple the guide will be open for the reception of the succeeding staple, substantially as described. 4. An implement for inserting metallio staples, consisting of two opposite jaws, one of which is provided with a staple-bonding recess, and the other, with staple-guiding grooves and an anvil fitted thereto, in combination with a knob to receive the blow of the hand and insert a staple by a sudden percussion, substantially as described. 5. In a staple-inserting machine constructed to operate substantially as described, the staple-guiding block B having stapleholding grooves C C, forming side extensions of the vertical slot S, substantially as shown and described. 6. An implement for inserting metallio staples, consisting of two opposite jaws, one of which is provided with a staple-bending recess, and the other with staple-guiding grooves and an anvil fitted therein, the said jaws being arranged to be separated and stand apart to admit the requisite manipulation for conveniently placing a staple in the open end of the said staple-guiding grooves, substantially as set forth. 7. The combination of the stationary staple support or anvil A' with the sliding guide B, grooved to partially embrace and guide the staple-legs, substantially as and for the purpose set forth. 8. In an implement for inserting metallio staples, a reciprocating driver provided with a knob to receive the blow of the hand, in combination with a grooved staple-guiding block and an anvil attached to a stand of convenient form for use upon a writing-desk, the said stand having an arm arising therefrom, and over and above it a guide for the purpose of guiding the said driver to the said anvil, substantially as and for the purpose set forth. The differences which thus appear in the descriptive parts of the specification are these: In the original, in stating the operation of the machine, it is said that the points of the staple point "upward" when the staple is within the grooves. In the reissue it is stated that those points are "turned toward the bending recess F." In the original it is said that the papers to be united are "placed upon the face of the guide B over the staple-points." In the reissue it is said that the papers to be united are "placed beneath the driver." In the original it is said that the guide B gives way, and the staple-legs come up through the papers into the recess F, where they are bent over preparatory to the final clinching. In the reissue it is said that the staple-legs come through the papers into the recess F, where they are bent over by the slanting ends thereof. The original then contains the following statement, which is wholly omitted in the reissue: The hand is now released from the knob of the driver, the latter then rising, and the papers are drawn somewhat forward, until the staple-crown rests upon the face of the guide B, when another blow is imparted to the driver, and the flat portion of its face descends forcibly on the staple-legs, so as to bend the latter close to the paper, thus completing the operation. The reissue omits the statement of the original that as the staple-legs strike the slanting walls of the recess they will be bent inward toward each other sufficiently to insure their being bent down properly when again struck between the faces of the guide B and driver E, aud substitutes the statement that when the staple-legs strike the slanting walls of the recess they will be bent inward toward each other, as shown in figures 2 and 3. The following sentence, not in the original, is found in the reissue: It will be seen that the staple support or anvil A', with the slotted or recessed hammer, operates to insert a staple through layers of stock to be united, and simulaneously bends over its projecting ends. The specification of the reissue then states that the separate operation described in the original of flattening down by a second blow the ends of the staple when bent over was not new, but that the legs of the staple, if not laid sufficiently close to the surface of the paper when bent over by the driving blow, may be further flattened down by a seeond blow between flat surfaces. Figure 5 of the drawings, though contained in the drawings of the original patent, was not described or referred to in the original specification; but the reissued specification speaks of figures 1, 2, and 3 as showing a hand-stamp in which the driver reciprocates in a fixed head in the manner of a plunger, while figure 5 shows a hand-stamp in which the driver is mounted at the end of a vibrating arm, pivoted at its rear extremity to the base, which rests upon the table; that the devices which constitute the invention are found in both of these modifications, and that both operate to insert, by a blow upon the knob G of the handstamp, a staple through layers of stock to be united, and to simultan. eously bend over the projecting ends in the opposite bending-recess provided therefor. On the question of novelty, the alleged prior invention principally relied upon is a patent of the United States No. 187,189, granted to George L. Ward and Orianna S. Smyth, assignees of James C. Smyth, February 6, 1877, for an improvement in machines for stitching books with staples. The circuit court, in its opinion, accompanying the record, held that the patented invention was not anticipated by that of Smyth; that claims 1 and 2 of the reissue were substantially the same as claim 4 of the original patent, when the latter claim was read in the light of the specification, and that the defendants' device infringed claims 1 and 2 of the reissue. Claim 1 of the reissue for a combination of (1) the stationary staple. support or anvil, (2) the sliding staple-guide, and (3) the reciprocating slotted or recessed hammer or driver, the conjoined operation of the three being to insert a staple through layers of stock to be united and to simultaneously bend over its projecting ends. Claim 2 of the reissue is for a combination with the same three elements, of (4) the spring D, and (5) the knob G. Claim 4 of the original patent was for a combination of only two of these elements, namely, (1) the stationary staplesupport or anvil, and (2) the reciprocating slotted or recessed hammer or driver. It left out the sliding staple-guide, and yet the claim stated that the combination of the two elements, without the staple-guide, would operate to insert the staple and simultaneously bend over its projecting ends. It would, however, wholly fail to so operate without the use of the sliding staple-guide. The use and operation of the sliding staple-guide, its arrangement so as to slide, the use of the spring D to keep it in its normal elevated position, so that it will not drop prematurely, and the use of the knob G, with which to impel the driver, |
