DEVICE FOR AUTOMATICALLY SUPPLYlNG STAPLES TO INDEPENDENT OR DETACHABLE STAPLE-DRIVERS.

SPECIFICATION forming part of Letters Patent No. 363,957, dated May 31, 1887.

Serial No. 216133. (No model.)

To CLZZ whom it may concern.-

of Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a certain new and useful Improvement in Devices for Automatically Supplying Staples to Independent or Detachable Staple-Drivers, &c., of which the following is a full, clear, and exact description, reference being had to the drawings accompanying and forming a part of this specification, in which Figure 1 is a longitudinal vertical sectional View through the working parts of a device embodying my invention, the hinged rear end and the attachments for moving. up the series of staples having been removed. Fig. 1 is'a view of the finger-piece H of Fig. 1 detached from the bar F. Fig. 2 is a transverse longitudinal view of the parts shown in Fig. 1. Figs. 2 and 2 are enlarged views of theparts form of staple-driver now in general use, and which is adapted to operate in connection with the supplying device, as shown. Fig. 4 is a side view on a reducedscale, partly in section, of adevice in complete form embodying my invention. Fig. 4 is a view of the rear cradle and its supports, and Fig. 4" of the front cradle, which together support the staplefeeding bar and the guide-flap, and between which is the staple-guiding slot F Fig. 5 is a top view of the guide-flap F and adjacent parts. Fig. 6 is a view of the follower, which occupies the staple-slot and pushes the series of staples along the same; and 'Fig. 7 shows different sorts of staples adapted to be used with the devices shown.

The lettering in all the figures is uniform.

My invention relates to theconstruction and operation of a device by means of which metallic staples-such as are used for fastening sheets of paper together in offices, binding up pamphlets, fastening boxes, putting down carpets, upholstering furniture, &c.may be automatically supplied to and inserted into an independent or detachable staple-driver, in which the staples are inserted singly and used one at a time, having the staple-holding channel separately supplied at its open end with a staple after the previous one has been driven,

in contradistinction to the staple-driving de- Vices, which either take their staples from a reservoir behind the driver or make their own staples and. drive them successively as soon as made.

The classofstaple-drivers for which my in vention is adapted have heretofore had the staples inserted singly by hand at the open end of the staplechannel crown foremost, the plunger afterward driving out the staple, and being again supplied by hand as each staple is driven. Notwithstanding the loss of time occasioned by having to pick up each staple separately from a box, stick, or pile of staples and insert the same into the driver, these staple-drivers have come largelyinto use, as they are cheap to a make, simple .to operate, and light and convenient to handle. these staple-drivers used, if desired, with a separate clinching device, is shown in my Letters Patent of the United States No. 226,402, dated April '13, 1880, in which the construction and mode of operation are clearly set forth; and such staple-driversare shown in Fig. 3 of the present drawings,-and are adapted other figures.

however, the parts being enlarged or modified to fit the same, and also to supply staples having more than two prongs, or asingle stem instead of a pair of legs, or staples with enlarged heads, or which have their legs constructed to be bent outward in clinching instead of inward, and fastening devices of other kinds adapted to be used with a driver supplied in the manner described.

Referring to the drawings, in Fig. 4. the device is shown as it stands upon the desk,table, or floor ready for use, the staple-driver (part view) being'shown suspended over the guide- A type of to be used with the device, as shown in the Any of the forms of independent staple-drivers in use may be used instead,

channel 13 and ready to be inserted therein end, being supported by a spring, G. A spring-follower, S, carries the series of staples along the slot, the legs of the staples hanging down on each side the bar and guarded above by the guide-flap. The follower is moved forward by a suitable spring. Facing the front end of the staple-holding bar is an upright post of the same cross-section, and behind this is a vertically-sliding'plate to prevent the spring which feeds the staples along the bar from carrying the forward staple over the top of the post D and into the space to be occupied by the case of the driver when pressed down from above.

Above the free or vibrating end of the staplefeeding bar and over the post D is a vertical guide channel or hopper, to direct the stapledriver downward at the proper place. The operation is as follows: The spring-follower moves the series of staples forward until the crown of the front staple is pushed out of the slot F and rests upon the top of the post D, the legs hanging down each side. The driver to be supplied with a staple, being inserted into the guide-channel B pushes down the front end of the staple-holding bar F F and the vertically-sliding plate E behind the post D. The post, remaining fixed, inserts itself at its upper end into the channel of the stapledriver K, carrying with it the staple which is suspended upon it. When the driver is removed, the slight outward spring or flare of the legs of the staple T holds the same in place in the channel of the staple-driver when it is withdrawn from the channel B of the device. The spring G carries up the end of the bar F and the plate E. The spring R moves up the series of staples until a new one occupies the post D, and the operation is repeated as often as the preceding staple has been expelled from the staple-driver and there are other staples upon the bar of the machine.

The staple-bar F, I preferto construct with a separate top part or guide-flap, F, having a longitudinal transverse slot, F between the bar and the guide-flap, extending from end to end and open front and rear, and of a size to freely admit the insertion of the crowns of a series of staples, the legs of which hang downward upon each side of the bar F.

To hold the bar F and the guide-flap F in place, I provide a support or cradle at each end, as shown in Figs. 4 and 4", which I make open on the inside and attach the bar F to the bottom and the guide-flap F to the'top, so as to leave room on the sides for the insertion of a series of staples from the rear, and also to admit the follower S. (Shown in Figs. 4, 5, and 6.) The front cradle, N, does not extend entirely around the bar and flap, but one side is left open to show the staples in place as they pass through the slot F and admit of their ready removal should a defective one be encountered, or for other reasons; but the opposite or rear cradle, L, I carry entirely around F and F, and provide sockets I Z at the sides thereof, by means of which I pivot it to the raised supports A A of the base A. The screws attaching these various parts are shown at a a, l l, and n n, though any other wellknown means of attachment may be used, if desired. The cradles L and N are each shown with a laterally-projecting lug or car, L and N.

From L to N, between the cradles, extends a rod, P, along the bar F, upon which is a coiled spring, R, closely but freely fitted thereto. The spring It acts upon a slide, M, so that when the slide is drawn backward the spring will carry it again to the front when released. The mannerin which I prefer to construct the spring and follower is as follows: The slide M has two projecting bearings, M and M Fig. 5. M fits closely to the rod P, and the spring R impinges against it from behind. M is enlarged sufficiently to allow the spring R to pass through it, andthe sides of the opening are rounded, so that it will slide freely to and fro upon the coiled spring R, which in turn slides upon therod P. The slide M is made of considerable length, as shown, and has a thumb-piece, M, by means of which it can be drawn back and forth, or raised up to free the follower S, Fig 4.

On each side the space occupied. by the guide-flap F, when the slide M is in place, extending from one end of the slide M to the other, is a light bar or strap, and to the under side of these bars of M, at various places along the same, are downwardly-projecting studs M M M M opposite each other in pairs and hooked toward the front to prevent their escape from the wings S of the follower S, with which they engage. By this construction I can vary the tension of the spring R upon the series of staples in the slot F at will, as I can hook one or another pair of the hooks M M,according as I require to increase or diminish the tension of the spring. The follower S, I clearly show in Fig. 6, and the same is shown in place in Figs. 4 and 5. I prefer to make'it of a light plate of brass or other metal, which I strike up from the sheet, having the sides S S bent down at right angles nearly, and the wings S S cut from the sides at S and left standing, as shown. I construct these wings S S near one or the other end, or in the middle, as I prefer.

The above-described rod P, spring R, slide M, follower S, and staple-guiding bar and flap F F, operating substantially as is herein shown and described, I not only use for the specific invention herein fully set forth, but also apply the same to all sorts of staple-feeding mechanism for self-feeding staple-inserting machines and for other like purposes to which the feeding devices may be applicable; and I prefer to use it in the self-feeding staple-inserting machines secured to me by Letters Patent of the United States No. 349,093, dated September 14, 1886, for which I have it much superior in efiectiveness, convenience, and cheapness of construction to those heretofore used in similar machines. When, in such machines, the staple-bar is not constructed to vibrate, I attach the rod P to the frame of the.

machine instead of the cradles shown. I sometimes also reverse the spring R, making it draw from the front of the bar F instead of thrust from the rear.

It will be seen in Fig. at that the base A ex-' tends forwardthe whole length of the machine,

and I provide holes a a at the ends,wherebyspring, G, attached at g, and supporting atits.

front end the staple feed-bar F against the downward pressure of the driver K as it descends in the channel B and impinges with its case upon the front end of F and the top of E. At the front end of the base A is an upright, B, attached, as shown in Fig. 4,

- by one or more screws or rivets, A to the base A. This upright B extends above the bar F and its attachments, and is provided with a vertical channel, B over the front end of the bar F, the post D, and the sliding plate E, which I expand at its upper end to insure easy guidance of the driver K to the channel B in its more closely-fitted portion below. For convenience, I usually form the channel E by joining a front and back piece, B and B; but the upright B may be formed in one piece, ifdesired, with the ch annel.B ,cored or otherwise made in the'same. In its lower half the upright B is left open behind to allow the free end of the bar F to play upand down therein, but at its upper part is closed to form the channel 13*, and against the under side of this closed part the bar and flat. F F impinge as they rise. and their upward motion is thereby arrested at a point where the top of the post D is on a level with the top of the bar F, as shown in Fig. 4.

The staple supporting and inserting post D is attached to the front side of the upright B, within the same, and for this purpose I provide an extension or projection, B Fig. 2, against which the post D is firmly screwed at d. This projection B is narrower than the face of the post D, and in the recess behind the said post and on each side the same there plays up and down the vertically sliding plate E, which is bifurcated in its upper part, but united at E below. (See Fig. 2".) The extension B,to which the post D is attached, only projects downward sufficiently far to reach the lower part of the bifurcation of the plate E and E is supported as it rises bythe impingement of E against the under side of said projection, and in its descent the arms E E are guided by the sides of the same; When the driver K is inserted in the channel B the rear side of the case of the driver engages with the top surface of the front end of the guideflap F, and at the same time'the front side of the drivercase, alongside the groove K, engages with the tops of the bifurcated plate E E, and carry down both the free end of the staplebar and the plate E, the groove of the driver being guided alongside the projection B and the top of the post D passing into the staplechannel of the said driver. A staple suspended upon the post D will .be inserted into position for driving into papers, carpet, or

other material, and beretained therein by the outward spring of its legs against the sides of the staple-channel, .or by friction if the fit be a close one. The projection B thus serves as an additional guide to the staple-driver and insures theinsert-ion ofv the post D into the staple-channel thereof.

When a staple-driver without a side slot is used, the post D should be attached to the base below, and not against the upright B and the projection B and the bifurcation of E will be dispensed with. It is much stronger, however, in its present form when light wire staples are used, as the post -D cannot be forced back against the plate E spring R.

To raise the sliding plate E to its proper .place, I attach to the free end of the staplebar F, underneath, a forwardly-extended finger-piece, H, which is also bifurcated at its forward end, as shown at h h, and which bifurcations embrace the sides of the post D, Fig.

1, and assist in accurately guiding-thevibrating end of bar F in a vertical plane. The bifurcated ends it h extend behind the sides of the post D into the space occupied by the sides down by the pressure of a staple-driver upon the top thereof, then, in its ascent, the bar F, by means of the finger H, will again raise the plate E to its place. It is very important to by the thrust of the IIO retain this plate E in place during the accidental movements of the free end of the bar F,

as otherwise the legs of a staple or the crown would slip back behind the post D and choke the feeding device, or prevent-the bar F from fully rising to its place. I prevent the plateE from dropping when the bar F is depressed by mere friction when it is very light, but if heavier a slight magnetization will increase the friction, or a light catch or spring may be used. a

The object of the spring 0, which may be constructed in various ways, is (see Fig. 4) to prevent a staple from being lifted prematurely from the post D.

It is attached to the'rearface of the channel B at B by its upper end,

and extends downward and forward obliquely, so as to cross the channel B in whole or part at its lower portion, and has its free end bent backward to increase the surface presented over the post D, above which it rests at about the height of a staples thickness. I slot or notch the front of F in the middle, as shown at F, Fig. 5, to accommodate the free end of this spring 0 as it is swept backward by'the descent of the staple-driverin the channel 13, by which means the spring is removed from over the post D untilthe staple driver has been removed, when, just before a fresh staple is projected from the slot F upon the post D, the spring passes over the crown of the staple and holds the same from rising,while the plate E prevents the staple from being pushed backward over the said post D. The front end of the staple-bar may thus be vibrated at will without displacing thestaple which at the time may occupy the post D, or the device may be hung upon a wall or inverted without danger.

In certain cases, as for very heavy staples, the spring U may be dispensed with; but for the reasons stated I prefer to use it.

I do not confine myself to the specific form of device shown, as I modify it in various wellknown manners to accomplish like purposes. and I sometimes slot the staple-carrying bar F vertically to carry nails, tacks, and other fastening devices, all of which may be readily done by any well-skilled mechanic from the construction and operation of my invention, as hereinabove shown and described.

To supply staples to the slot F, I usually provide the'same strung on sticks or rods, as have been well known for blindslat and other staples heretofore, and one form of such'rod or stick which is well adapted to my present invention has been secured to me by Letters Patent of the United States No. 349,094, dated September 14, 1886, from which stick I pour the staples upon the bar F from the rear, the follower S having been previously removed from the slot F. F, upon its under side, I usually provide a shelf, F, with slightly-upturned sides, upon which the end of the staple-stick may rest during the operation of supplying the staples to the slot F Having now described my invention, what I claim, and desire to secure by Letters Patent, is-
