MACHINERY FOR STITCHING BOOKS WITH STAPLES.
SPECIFICATION forming part of Letters Patent No. 223,252, dated January 6, 1880.
Application filed March 10, 1879.
To all whom it may concern Be it known that I, JAMES C. SMYTH, of Boston, in the State of Massachusetts, have invented an Improvement in Machinery for Stitching Books with Staples, of which the following is a specification.
This invention relates to adevice for driving staples through books, pamphlets, or sheets of paper or other material, bending up the ends, and compressing the staple firmly to the material.
In the drawings, Figure l is a vertical section of the machine. Fig. 2 is a plan of the same; and Fig. 8 is a sectional elevation, showing the sheet-holder, plunger, magnet, bending-slides, and hammer.
The staples are fed upon the staple-bar c by any convenient means-such, for instance, as those shown in my Patent No. 187,189. These staples slide down the bar 0, and the end staple is attracted to and held by a magnet, (0, which may be an electro-magnet, but is preferably a permanent magnet attached to a movable block, I, hereinafter described. This magnet prevents the staple dropping, for there is a channel for the staple between the face of the magnet a and the end of the staple-bar c. There are openings at the sides of the bar 0 for the ends of the staples to enter freely into the vertical channel; but this channel is of a size adapted to receive and hold a staple of a certain size of wire but the length of the prongs of the staple should be only sufficient to pass through the book and be bent up or clinched.
The staples varyin length. Hence the machine has to be adapted to thelongest staples, the openings at the sides of the staple-bar 0 being sufficientlylong for such staples to pass into the channel.
The lowest staple, regardless of the length of its prongs, is held by the magnet at one side of the channel, and the other staples upon the bar 0 cannot descend until this staple is carried down by the plunger 6 and driven through the book. The plunger 0 rises and the staples slip down the bar, and another staple is attracted by the magnet.
It is to be understood that the plunger 6 is driven by any suitable means. I have shown screws 5.
the lever f and cam h upon the revolving shaft 75 as the means for moving this plunger.
The magnet will not'exert enough power to interfere with the plunger in slippingthe staple along its surface, but such magnet will insure the proper position of the staple.
In order to guide the staple at the surface of the book, I make the block I, that carries the magnet, and in which is the staple-channel, movable vertically between the stationary 6o head-block m and the cap-plate n, and there is a spring, 2, to raise this block to allow for the insertion of the book between its lower end and the surface of the bed 0; and springs 3 3, between the plunger-carrier i and this block I, serve to force the block 1 down to the surface of the book as the plunger-carrier de scends, after which the staple is driven by the further movement of the staple-driver.
The cap-plate n is hinged at the top, so
that it can be swung forward, together with the plunger and block I, to give access to these parts, if necessary, and said cap is retained in place by the turning buttons t.
The bed 0 can be raised or lowered to suit different thicknesses of books by the screw or There is a mortise in the surface of the bed 0, intowhich the ends of the staples pass, and in the bed are the two bending-slides s s, that are in line with the mortise, and there is also a vertical sliding hammer, 1", that is in the mortise below the surface of the bed. Cams 9 9 and 10 upon the main shaft 70 actuate these bending slides s and hammer 1 through the agency of levers 11 11 and 12, respectively. The shapes of the cams are such and the p arts are timed so that after the staple is driven through the book the driver 0 pauses, the bending-slides s 8 come up, bend the staplepoints toward each other, and then fly back, and the hammer r flattens the points against the book.
I claim as my invention-- 1. In a staple-driving machine, a magnet against the face of which the side of the staple 5 is attracted and kept in position, in combination with the staple-driver that is moved along the face of the magnet toward the book, and the means for supporting the book into which the staple is driven, substantially as set forth. 10o

The block 1, adapted to move vertically, the book, and a hammer, 1", acting upwardly and provided with the channel for the staple, to clinch the ends of the staple, substantially in combination with the plunger-carrier and as set forth. plunger for driving the staple and moving the Signed by me this 30th day of September,
