MACHINE FOR BINDING BOOKS WITH WIRE STAPLES.
SPECIFICATION formingpart of Letters Patent No. 228,874, dated June 15, 1880.
Application filed August 1, 1879.
To all whom it may concern:
Be it known that I, WILLIAM L. Coor, of
the city and county of Providence, and State of Rhode Island, have invented a new and useful Improvement in Machines for Binding Books with WVire Staples; and I hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specification.
This invention has reference to improve ments in machines used for securing papers, pamphlets, or books together by means of wire staples; and it consists in the peculiar and novel arrangement of the various parts by which the staples are cut from the wire, supplied usually from a spool, are bent, formed, driven, and clinched automatically, as will be more fully set forth hereinafter.
Figure l is a perspective view of the binding-machine provided with a reel containing a quantity of wire suitable for staples, an auto matic arrangement for feeding the wire, cutting the wire into suitable lengths, bending the same into staples, driving the staples through the paper, and clinching the staples. Fig. 2 is a sectional view of the machine,
showing the devices for feeding the wire and clinching the staples. Fig. 3 is a sectional view,showing the working parts all in the position occupied by them when the staple has been inserted and clinched, the book or papers being shown compressed by the presser-foot. The line of this sectional view is marked on Fig. 2 vertically through the central portion of the machine. Fig. 4 is a horizontal section,
on a line marked w in Fig. 3, of the wire-cut ter, the staple-former, and the driver, on a line with the fixed part into which the wire is fed to be cut off by the cutter, and shows the wire inserted in the groove in which the stapleblank is cut from off the main length of wire. Fig. 5 is a vertical sectional view, showing the presser-foot in contact with the hinged cutter and the wire inserted in the groove of the staple-former at the moment the cutter has severed the wire and the two sides extending from the presser-foot are ready to descend and bend the wire into a staple. Fig. 6 is a sectional view, showing the driver ascending and about to come in contact with the levers by means of which the cut wire is the presser, and also to push the staple previously bent under the driver. Fig. 7 is a perspective view of the levers (shown in the same position as in Fig. (i) at the moment when they push the wire into the former and the staple under the driver. Fig. 8 is a sectional view of the fixed portion containing the groove into which the wire is fed, and a view of the presser and driver at the moment when they descend to form a new staple and drive the formed staple through the paper. Fig. 9 is a cross-section of the guides, the driver, the presser, and the levers for moving the wire and staples on a line marked 3 in Fig. 3. Fig. 10 is a sectional view of the end of the feederarm, showing the cam by which the wire is held when feeding the wire, but which will slide over the wire when moving toward the reel.
Similar letters of reference indicate corresponding parts.
In the drawings, A is a hollow standard, and a a raised platform, on which the paper rests, and within which the clinching device is secured. B is a spool of suitable wire for the desired staples, supported on a stud or pin, on which it revolves. b is a thumb-screw, by which the spool is secured on the stud or pin. A spring-washer or other device is placed between the spool and standard, or between the spool and thumb-piece Z), to prevent the spool from rotating too freely and to secure the proper tension'on the wire.
0 is the main actuatinglever, by which all the operations, except the feeding and clinching, are performed, the latter being performed by the lever D, which, with the arm F, forms a bell-crank lever. By raising the lever D the arm F feeds the wire while the inserted staple is clinched.
The wire is fed into a groove, to, extending entirely through the projecting case A, within which the driver, the presser, the former, and the hinged levers for moving the wire are secured.
fis the hinged cutter, which is operated by the presser-foot g coming in contact with the Y curved arm of the cutter, as shown in Figs. 1 and 5.
9 is the side or extension of the presser, surrounding the driver on three sides. It is secured to the driver by a spiral spring, and moves with the driver. At its descent the presser first comes in contact with the paper and compresses the same, the pressure becoming greater as the driver descends and compresses the spiral spring.
By connecting the driver with the presser 'by means of the spiral spring varying thicknesses of paper can be secured together.
As the wire is to be bent by the extension g of the presser, as shown in Figs. 5 and 8, a positive motion is required at that portion of the downward stroke. The rear portion of the presser is provided with the projection 1 and the connecting-link g, by which the driver is connected with the lever O, is extended below the connecting-pin I), and at the first portion of the downward stroke, when the staple is being formed, the extension of the connectinglink g rests on the projection g of the presser and exerts a positive pressure. As the lever descends it moves of from the projection, as is shown in Fig. 2, and the driver only is operated directly, the presser being held by the force of the spiral spring, by which it is con= nected with the driver.
To regulate the distance from the edge at which the staples are to be driven the guides E E are connected with the arm 0, and are operated by the thumb-piece 0, located in the rear of the standard, by which a screw secured to the thumb-piece is turned, and as this screw works in a nut on the arm 0, both the guides E E are drawn in or pushed out by the turning of the thumb-piece e in one or the other direction.
2' 11 are the hinged levers by means of which the wire is pushed into the recesses a formed on the side slides of the presser, to form the staple, and by which, also, the previously.
.formed staple is pushed into the longitudinal grooves a of the staple-former under the driver, so as to be driven into the paper.
It will be observed that the longitudinal lateral projections b of the driver engage with the projections biformed on the upper extremities of the spring-pressed levers i, and thereby cause the lower working extremities of said levers to operate in placing the formed staple into groove a of the staple-former beneath the driver, and to place the staple-blank into groove a The clinching apparatus consists of two cams, K K, located in the raised platform a, and are operated by the toggle-jointed levers Z Z and m m, connected with the lever D, as is clearly shown in Fig. 2. A stout spring, a, is connected with the lever O and the standard, to raise the lever.
A pivotal clamp, b (shown in Fig. 10,) serves to draw the wire from off the feed-roller, permitting the wire to pass through arm F in direction to feed the wire to the groove a, and preventing the wire from being moved in the opposite direction. A similar springpressed clamp, b secured within casing A, as shown in Figs. 5, 7, and 8, serves to hold the staple-blank in position while being operated upon.
The operation of the machine is as follows, viz: The guides E E being adjusted to the desired position, a number of sheets of paper, a book, or pamphlet is laid on the platform a, the edge resting against the guidesE E. The lever G is now pressed downward, which first brings the sides 9 of the presser against the projecting ends of the wire in the groove (L2 and forms a staple. By the time the staple is formed the arm g moves off from the projection 9 the presser descends onto the paper, and firmly compresses the same, the driver follows and forces a staple through the paper. At this point the hollow of the hand pressing on the lever O, the fingers of the same hand raise the lever D, which causes the cams K K to bend the projecting ends of the staple and firmly clinch the same, and at the same time the arm F of the lever D delivers a length of wire into the groove a. The lever G is now raised; the presser-foot comes in contact with the curved arm of the cutter f, which cuts off the length of wire to form a staple; the ascending driver comes in contact with the levers M, whereby the cut wire, as also the previouslyformed staple, are pushed respecf vely into grooves a and a as shown in Figs. 6 and 8, the finished staple under the driver, and the cut wire to meet the bending device on the presser.
It will be observed that upon release of the lever D the arm F returns to its normal position. The whole is now ready forthe driving of the bent staple and the bending of the new staple at the next descent of the driver and presser.
At each operation a length of wire is delivered, a staple is bent, a staple is driven and clinched, all the functions being performed, by means of the levers G and D, with one hand and with but slight exertion.
Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. In a staple-forming and staple-driving machine, the combination, with a lever which has pivotal movement in a vertical plane, of a staple-driver to which it is directly connected, a staple-former provided with a presser-foot at its lower extremity, and a spring which connects said staple former and driver, substantially as set forth.
