To all whom, it may concern:

Be it known that I, CARL LoUrs-LAsOH, a subject of the Emperor of Germany, residing at Reudnitz-Leipsic,in the Kingdom of Saxony and Empire of Germany, gentleman, have invented new and useful Improvements in Apparatus for Binding Books and- Similar Objects with Metallic Staples, (for which I have obtained Letters Patent in Great Britain, No. 16,138, dated December 8, 1884; in'Germany, No. 80,993, dated October 18, 1884; in France, No. 165,527, dated November 22, 1884; in Belgium, No. 66,974, dated November 22, 1884; in Italy, No. 17,650, dated December 3, 1884, and in Austria-Hungary, No. 44,466 and No. 15,286, dated November 24, 1884, of which the following is a specification.

This invention consists in certain features of novelty, which are hereinafter particularly pointed out in the claims, being first fully described with reference to the accompanying drawings, in which- Figure 1 is a side elevation of the complete apparatus, a portion of the head being shown in section. Fig. 2 is a front end elevation of the same, a portion of the frameot' the machine being broken away to show the springs which hold the clinchinghcad in elevated po- Fig. 3 is a detail view of the clinching mechanism. Fig. 4 is a sect-ion on theline 4 4, Fig. 5, looking in the direction of the arrow. Fig. 5 is a detail view showing portions in section and portionsin elevation. Fig. 6 is a plan view of the head in which the staplcdriver works.

The frame of the machine consists of a single casting comprising a base portion, A, and two arms extending upward therefrom, the forward one, A, of which carries at its upper end the mechanism for supporting the signature while it is being stitched and for clinchingthe staple,while the roar one, A, supports the staple-driving mechanism. The whole of the statendency being to hold the front end of the arm 9 in elevated position.

A is a lug projecting from the arm A for limiting the extent to which this arm 9 shall be moved by the spring 1. That part of the arm 9 which projects rearward from the fulcrum q may be of any shape, that part which projects forward being of the shape in cross section which is shown more clearly in Fig. 4that is to say, its top side isrof rectangular shape, so as to form a saddle, a, over which the staples hang, as shown at s in Fig. 5, its under side being broader, as hereinafter described. The staples are fed forward to the staple-driver by a rod, I, under the influence of a spring, 70, the forward end of the said rod being provided with a follower, Z, which is of a rectangular shape (corresponding to the shape of the staples) and extends downward on both sides of the saddle nin the manner shown in Fig. 5, so as to maintain the legs of the staples in planes perpendicular to the movement of the bar Z.

9 represents a cap or cover whose exterior may be of any desired shape, but whose interior is of such shape as to fit snugly over the saddle n and bar Z, leaving only the necessary rectangular space as for the passage of the staples. The formation of this space of proper proportions may be insured by forming the arm 9 with rabbets g, for the reception of the lowermost portions of the overhanging sides of the cover, the offsets or shoulders 9 being of such size as to compel the inner walls of the cover to leave the proper space as. The front extremity of this cap or cover is enlarged so as to form the rearside of the head B in which the staple-driver works, and is in addition provided with bars 9, projecting downward over the sides of the'bottom flange of the arm 9, said bars and also the arm being perforated for the passage of a single pin, 9, by which the cover is securely held in place. The face of the enlarged front end, of the cover 9 is form-ed with a rectangular rib or projection, g, which forms the rear wall of the channel through which the staples pass. Secured to the front side of this enlargement 9 by screws 9', is a plate, 71, of the peculiar shape shown in Fig. 6, its inner side being cut away to form a passage-way for the staple-driver e and a channel for the staples, the latter being of slightly greater width than the former. The Staples move in the space left between the outer face of the rib or projection g and the shoulders h of the plate h, while the driver 6 moves 1n the groove cut in the plate h between the shoulders lb.

The front edge of the driver 0 is grooved vertrcally, as at c, for the reception of the extremity of a screw-plug, If, which passes through a screw-threaded aperture formed in the plate h, a stop, 6, being secured to the driver e within the groove 6", for impinging agalnst the inner end of the screw If, and

thereby limiting the extent to which said drivershall move upward independently ofthe head. The driver 6 is operated by ahand-lever, d, whose rear extremityis hinged to the upper end of a link, i, the lower end of which link.

is hinged at a to the arm a, said lever being provided with a hook, d, for engaging a pin, 0, pro ecting from the driver a. This hook is held in engagement with the pin 0 by the spring k, whose extremities are secured, respectively, to the link t and to the feed-bar Z, said spring being thus made to do double duty. The support for. holding the object to be stapled is secured to a head, a, secured to the upper extremity of the arm A by means of pins and slots a, which permit said head to move for a short distance in a vertical plane. This head is held normally in elevated position by means of a pair of plate-springs, f, placed 111 upright positions, their upper ends being in engagement with the underside of the head,while their lower ends rest upon shoulders formed on the frame of the machine. This head is formed with a narrow slot, a, between the vertical walls of which are pivoted a pair of bending-plates, b, whose adjacent free extremities bear upon the top side of a fixed anv11, 0, pro ecting upward within the slot a. For the purpose of more clearly representing the slots (1 the clinching-plates b are omitted from Fig. 5. On reference to Figs. 2 and 3 it will be found that their top sides are straight instead of inclined in a curved manner toward the free extremities of the plates, as is the case with an existing device with which I am familiar. If the top sides of these levers are curved, they will have the effect ofbending the staples in the maunerin which it is the object of my invention to avoid-z. e., as shown at s. It is also desirable to pivot these levers in a narrow slot, a, having parallel walls which fit close to their sides and serve as braces to maintain them, constantly in a vertical plane.

When the signatures of books are to be stapled for supporting them, I prefer to employ thin rules or knife-edges m,which are secured to the vertically-movable head a, so as to form acontinuation thereofprojecting on both sides of the machine. Bysecuringasupport of this character to the upper end of the arm A, the two sides of the signature may fall smoothly over itsopposite sides and the stapling be done directly at the fold. A flat table, m, may, however, be provided, as shown by dotted lines in Fig. 1, its under side being provided with brackets in, which embrace the opposite sides of the rule for holding it in horizontal position, notches m being formed in the upper sides of the rules m for permitting the tableto fall until its upper face is flush with the upper edge of the head a. This table is of course apertured,for the passage of the head a, and is also provided on its upper side with a guide or stop, m for guiding the article to be stapled to proper place.

The operation of the machine is as follows: The machine may be charged with staples by removing the plate It and inserting the staples one by one, or, instead of this method, the cap or cover 9 may be removed by with drawing the pin This being done, the feed-bar, is retracted, by pulling upon the hook Z, and held in retracted position until the desired number of staples have been placed astride the saddle a. The capis then replaced and the feeder released, whereupon the machine is ready for operation. The handle (I being raised, a staple will be fed into the channel in the head B, and the head being held normally elevated by the spring t, it is neces sary to depress it so that its lower side will have contact with the article to be stapled. For this purpose the screw-plug It may be enlarged into a handle. The head being depressed into the position shown in the drawings, pressure is exerted downward on the handle d. During the first part of the descent of the plunger 6, and until the staple has been driven completely through the arti-. cle to be stapled, the clinching-head a is held in its elevated position b'y the springs f; but so soon as the staple-driver reaches the limit of its downward movement within the head B a pin, 1), projecting therefrom comes in contact with the top side of the head B, thereby compelling said head to descend with the lever (1, overcomesthe resistance of the springs f, and causes the head a to descend. This movement of the head causes. the plates 1) to assume the position shown in Fig. 3, and to clinch the staple in the manner already intimated.

Springsff of the character herein shown and described are preferable, for the reason that they exert their greatest strength to support the head a until the staple is inserted in the work, after which further pressure will cause them to bend and allow the headn to descend for the clinching operation, their resistance to the downward movement decreasing in proportion to the extent to which they are bent. Coiled springs would not answer the purpose, for the reason that they would exert their least pressure during the insertion of the staple, and their resistance would increase as the head descended.

Having described my invention, the followtog IIO

ing is whatIclaim as new therein and desire to seeureby Letters Patent:

1. The combination of ahand-lever, d, having a hook adapted to engage the staple- 5 driver 6 with said driver, a link, 1', and a spring, 70, the said link and spring being adapted to keep the lever d in gear with the pin 0 of the driver, substantially asset forth.

2. In a book stapling machine, the combiro nation, with the head 13, the staple-receptacle, and the staple-driver, of the handle (I,

engaging said lever, the link 2', the feed-bar Z, and the spring k, connected at one end to CARL LOUIS LASGH.
