50 (LZZ whom it may concern.-

Be it known that I, Isaac \V. Hnvsnvcnn, ofPhiladelphia, in the county of Philadelphia and State of Pennsylvania, have invented a certain new and useful Improvement in Machines for Inserting Metallic Staples in Papers, &c., of which the following is a full, clear, and exact description, reference being had to the drawings accompanying and form ing a part of this specification, in which- Figure l is a horizontal sectional view through the staple-driver and its coacting parts. Fig. 2 is a front view taken along the dotted line 1 y of Fig. 1. Fig. 3 isaside view from the side occupied by the staple-feeding bar. Fig. 3" shows different equivalent forms of the follower which moves the staples along the bar. Fig. 4 is a vertical sectional view along the dotted line gt a of Fig. 1. Fig. is a side view of the machine, from the side opposite that shown in Fig. 3, and shows the arm raised. Fig. 6 shows the staple-bar, which I furnish withthe machine, supplied with staples and ready for use. Fig. 7 and Fig. 7show different but practically equivalent forms of the clamp used to hold the staple-feeding bar in place; and Fig. Sis an enlarged view of the end of the staple-bar and the parts of the machine to which it is related in place,

The lettering in all the figures is uniform. My invention consists, iirst, in the construction of a selffeeding staple-driviugmachine either for hand or foot or power use, in which the staples are delivered into the machine, from a longitudinal staple-feedingbar carrying a series of staples, which are delivcred into the'machine not directly under the plunger or driver thereof, but alongside the vertical axis of the same, and thence carried laterally under the plunger by a transverselyreciprocating head block or carrier, actuated either independently of or in connection with the motion of the plunger or driver, so that the staples will not jam against each other in the staple-guiding channel of the driver from any accidental or incomplete movement of the plunger, asis the case when the staples are fed from a feed-bar immediately under the plunger; secondly, in combining with a staple inserting and clinching machine having a vibrating arm carrying staplerdriving meohan- (No model.)

so that the latter may he raised to have stapies inserted at the open end of the stapleguiding channel thereof of various sizes, a-

.self feeding device consisting of a staple-carrying bar supplied with a series of staples pressed forward into the machine external to the line upon which the plunger operates, and

having a transversely reciprocating head block or carrier constructed to carry the staples singly across the face of the machine and under the plunger, and adapted to be used eitheras aself-feeding orasingle-feed machine, may be desired; thirdly, in the use, in a selffeeding staple-drivingmachine, of a longitudinal staple-carrying bar consisting of a body upon which the corners of the staples rest, lying against each other, and having their legs extending down along the sides thereof, and provided with a tongue or flap extending along the length of said bar, attached at one end and having the other free, so that the staples may be fed directly into the machine by a :follower traveling along the said bar behind the staples, the flap or tongue acting as a guide for the staples while being fed into the ma chine singly, and as a protection to the staples strung upon the bar during transportation thereof, or when not required for use.

I do not, however, claim in this application the detachable or detached staple-holding bar or stick of wood or metal described and shown herein, except as a part of the staple-driving combination in which it is used, as the said staple-holdin g stick forms the subject of a separate application dated April 17,1886, Serial No. 199,176, which is now pending in the United States Patent Office, and in which it is fully ICO ing arni,A, which carries at its free end the staple-driving mechanism, and rests by its own weight u pen the paper or other material to be stapled. The base B is provided at its forward end (see Figs. 3 and 5) with a raised clinching-anvil, B, which contains aclinchinggroove, B", upon its upper surface, which may be of any of the forms in use for like purposes. I show the front of this anvil sloped off, so that papers may be pushed under the driver, if desired, withoutraising the same by hand. \Vhen the arm A is raised, staples like a, b, or c, or suspension ring staples, like (I, Fig. 5, may be inserted in the open end of the stapleguiding channel A, and when the arm is depressed and the plunger forced down they will be driven through any papers interposed between the driver and clincher, and the legs bent inward or clinched upon the grooved face of the anvil 3. B is a stiffening-rib on the base, and B a sliding guide to regulate the distance from the margin of the papers at which the staples are to be driven.

Referring to Fig. 2, A is the driver-head of the swinging arm A, to the front face of which is attached, by screws A" A A" A,a front plate, I), (see Fig. 1,) which holds the parts in place and is suitably recessed for the purpose. F is a staple driver or plunger, supported by the coiled spring F, and reciprocating vertically in a channel in the head, as shown. It is pro- 'vided at its upper end with a large rounded hind-knob, F; oralcvermaybeusedinstead,or in power-machines a rotating care, so that by pressure upon the head of the plunger the same will be forcibly driven down. F is a blade forming a downward extension from the bottom of the plunger F, and it rests above the crown of a staple when in position for driving, which said staple is driven downward through a narrow staple-guiding channel, A, as the plunger descends. \Vhen a clincher is used, the legs are clinched upon the grooved anvil 13* beneath. E is a transversely-reciprocating head-block or carrier, which traverses laterally across the line of vertical motion of the plunger F and the driv ing-blade F, and a groove, E, is made in the rear side of the carrier E, which permits the vertical passage of the blade F", as shown in Fig. 1; or the carrier may not extend entirely across the face of the machine, but may be a transverscly-reciprocati11g blade approaching the line of descent of the plunger, and then receding therefrom laterally, so that a staple lying in front of the said transverse blade would be carried under the plunger by its motion toward the same; but I prefer to use the grooved head-block E, as it is more certain of operation, and a staple in the groove 13* would be carried to and fro as the head-block was reeiprocated, so that a fresh staple could not enter the groove E until the preceding one had been driven out by the plunger F. The groove E conforms to the size and shape of a staple lying flatwise therein, the legs pointing downward. lf staples with slightly flaring legs are shown, as in Fig. 7, the groove will be slightly wider below; if staples with straight legs, as in Fig. 7, the sides will be vertical. When pushed to the left, the motion of the head-block E will be arrested by the stop E, and in its return the head -bloek will be stopped by the lug or stop IE. Within these limits it is free to travel to the left, and is brought up sharply to the right by a spring, 0, which maybe of any desired form or construction, though I prefer to use a simple coiled extension-spring, as shown in Fig. l. Vhen pushed to the left, the groove R will occupy the space marked by a dotted staple, L. This staple, Fig. 2, lies behind the headblock, and is the terminal staple of a series strung or otherwise arranged upon a longitudinal stapleholding bar extending back from the dotted staple of Fig. 2 in the manner shown atJ in Fig. 1. This series of staples lying flatwise against each other is carried forward under tension by a spring-follower, K, (see Fig. 3,) so that the staples, which are prevented from lateral escape by the flap or tongue J, are pressed forward along the slot J", the terminal staple abutting against the smooth rear face of the headblock or carrier E. if the groove E is empty and the headbloek E be pushed to the left to its full extent, it will slide along the front:- end of the series of staples until the groove 1 7" comes opposite the staple-bar J, when a single staple will be projected into the groove F1 and the series of staples L will move up one space along the slot .l". W hen pressure is removed from the head of the carrier E the spring 0 will suddenly return the carrier to its place, and the groove E-', carrying the staple, the latter will be placed directly under the driving-blade F. A blow upon the top of the plunger F will drive the blade F down through the groove E and the staple-guiding channel A, carrying the staple before it, and drive the legs of the staple into any suitable material beneath.

It will be seen that the plunger cannot descend unless they carrier is in place, with its groove ll beneath the same, nor can two or more staples be carried under the blade F at one time, as the staple will remain in the groove F1 ifit be again reciprocated, and block the entrance to any succeeding staple until the former one be driven out by the descent of the plunger.

As the staple has sometimes a tendency to drop a little in the groove Ft when carried over the stapleguiding channel A", unless somewhat carefully fitted, so that the legs are likely to be caught and the staple injured by being carried back accidentallya second time in the carrier, I usually make the carrier E of hardened steel and magnetize it, or provide it with a suitable holding attachment, so that a staple lying in the groove E will be attracted and adhere to the bottom of the same without tendency to slip or drop. I also sometimes, instead of the carrier, magnetize the drivingblade F, so that the staple will slide along its ITO under surface in contact therewith; but I prefer the former, and if the parts are carefully.

fitted the staple will be held mechanically and no magnetization will be necessary.

As often as the carrier is reciprocated and the staple driven out a new one may be taken up and the operation go on continuously until the staples upon the bar J are exhausted, when the bar is removed and a fresh one filled with staples is put in place. I make these bars to hold from one hundred to five hundred or more staples, and usually provide them of wood or other cheap material, and furnish them already filled for use in the machine, and they may be thrown aside when empty or refilled at pleasure.

-While the bar J is in use, or at any time it may be desired to use staples of odd sizes, such as are not at the time upon the feed-bar, or to use a suspension-ring staple, such as is shown at d, Fig. 5, in such case the carrier E is merely left in place, instead of being reciprocated, and the arm A being raised, as shown in Fig. 5, the staples are inserted singly at the open end of the staple-guiding channel A crown first, and when the bar is brought down the staple will be driven and clinched, as in ordinary single-feed staple-inserting machines. To accommodate the laterally-extended loop of a suspension-ring staple, as shown at d, Fig. 5, the rear side of the stapleguiding channel A is recessed at its middle part, with a notch extending through the same, as shown at A", Fig. 2.

Instead of operating the carrier E by indeendently working it laterally to the left, I metimes use a rightangled lever to move the same to the left by a vertical motion of the arm, the lower end of which is pivoted to the sliding carrier, and the angle pivoted to the frame of the driver D; and, in power-ma chines, for instance, I sometimes attach this lever to the plunger, so that the upwardmotion of the plunger may operate the carrier, or I work the carrier and the plunger from one or more cams by the same belt or gearing. For a simple cheap hand-machine I prefer the form shown in Fig. 2.

The face-plate D is screwed onto the face of A and holds the plunger, the springs, and the carrier in place, forming a case for the same. The line of parting of the castings is shown in Fig. 4. It will be seen that the front of A is substantially a flat surface, the grooves and channels for the most part being formed in the cap D. The hollow roll or head D conlains the spring 0, which may, however, lie outside, if desired. The head-block E reciprocates in grooves somewhat wider than the grooved bead D. down from D. nearly to the headblock E, and at E is a screw or post raised upon the front side of E. A coiled spring, 0, stretched from one to the other, serves to return the carrier to its place and hold it there. The vertical groove D crosses the groove D, and, in conjunction with an opposite groove on A car- At D is a post extending ries the plunger F. At the lower part of D the staple-guiding channel A is also preferably formed in the cap D, through which, as well as through E, the plunger-blade F descends in driving the staple. I modify my machine to drive shoenails, tacks. glaziers points, 850.,

Without departing from the principles of my invention, as will be obvious to any one skilled in the art to which it pertains.

The construction of the staple bar or rod J, to which, however, I make no claim in this application, except as a part of my generic combination, is clearly shown in Fig. 6, and in end view in Figs. 7 and 7. It consists of a long rod of wood or metal, substantially of thesectional form shown, and is provided with a tongue or flap, J, extending along the top of the same, attached at one end to leave an open groove, J, rather wider than the thickness of the wire of which the staples are made, and which staples I usually make of Bessemer or other steel or iron wire, and having the op posite end of the tongue or flap J free, so that the staples may be pushed out of the slot J by a follower moving behind, the flap J acting as a guide to prevent their being pushed off at the side, and directing them along the slot and out from the open end of the same. I usually prefer to make these staple-bars of wooden strips of a proper size and length, sawing the slot J into the same from one end nearly to the; other with a band-saw or other smooth saw. The unsawed end I prefer to protect against splitting by a small nail, J. Having strung this bar full of staples, I secure them by tying a cord or elastic band over the end, as shown in Fig. 6 at J", which securely holds the flap down and keeps the staples in place. Instead of a cord or band, a small nail may be used; but I do not prefer it, as itroughensthe deli very space. These staple bars,'already filled may be provided, at no perceptible advance in price, over staplesin boxes, and they are all ready for use in the machine.

lt will be seen (see Figs. 6 and 8) that the end of the flap J is beveled or provided with an offset, J'". \Vhile not absolutely essential, I prefer to use this to keep the slot J open while the staples are being fed into the machine. Upon D is a beveled projection, D, matched to J, so that when the staple-bar is pushed into the machine the bevel J of the flap J will impinge against and rise upon the bevel D of the machine, thus spreading the slot J and holding it open. Where the follower-spring is of considerable strength, this will usually suffice without these bevels or oil'- sets. A filled bar, J, being ready to be inserted into the machine, the front end willbe inserted, the band J 7 having been removed or stripped back underneath -the overhanging head A of the machine and over the socketed support A", Fig. 8. The middle or rear part of the bar J will be supported by the clamp A A, attached to the arm A. Restingin place in the clamp, it is tightened up by the screw in Fig. 7 or the springclampin Fig. 7. The

front end of J is closely applied to the rear face of the carrier I. The springfollowerK. which is attached in the figures to one end of a clock or other spiral spring, M, turning upon a post, M, to which its inner coil is fastened, is drawn back and hooked over the end of the staple-bar J, the projections K K of the follower K, or a small removable pin in lieu thereof, as shown, (see Fig. 3,) entering through the grooves J J, made in the unsawed end of J, and traveling along the groove or slot J, so as to push the staples along. The lower parts of the sides of K extend down alongside the red .I and embrace the legs of the staples Ii, so as t 0 push them evenly along. At Ii the sides are shown extending in advance of the body of K, to pass into the machine and deliver the final staples of the series. The clamp A" A may be anywhere along the length of the rod J, and I sometimes place it so as to hind at J at the unsawed end of J.

\Vhilc I prefer to feed from my staple-bar directly into the machine, I sometimes strip the staples from my bar, provided with its retainingtongue or flap J' onto a metal bar permanently fixed in the machine. The de tachable bar, however, enables the mechanism to be examined from behind, should a staple catch, by merely detaching the bar J, instead of taking off the plate I), as would otherwise be requisite. Instead of the clock-spring M )1", I sometimes use a simple coiled spring or an elastic band; but I prefer to use the form shown as being more sensitive and COl'lVOllICllh.

\Vhen the clincher I3 is not required, as when a simple driver is used, I dispense with the base 13 and its parts and furnish the selffeeding driver, as above described, without aclinchcr, and with or without a handle, A. For making up boxes, upholstering furniture, wiring blinds, and for various other purposes my invention isthns extremely desirable.

Instead of having the carrier reciprocate in a right line transversely to the axis of the plunger, I sometimes construct it to move at various angles thereto, or upon the arc of a circle, and I otherwise variously modify my machine without departing from the principles of my invention as hereiuabove set forth.

Having now described my invention, what I claim, and desire to secure by Letters Iatcut, is
