UNITED STATES PATENT OFFICE.
HENRY P. FEISTER, OF PHILADELPHIA, PENNSYLVANIA.
BOOK AND CARD CORNER ROUNDING MACHINE.
SPECIFICATION forming part of Letters Patent No. 242,192, dated May 31, 1881.
Application filed October 1, 1880. (No model.)
To all whom it may concern:
Be it known that I, HENRY P. FEISTER, a citizen of theUnited States, residing in the city and county of Philadelphia and State of Pennsylvania, have invented a new and useful Improvement in Book and Card Corner Rounding Machines, of which the followingis a specification.
My invention relates to an improvement in self-clamping book and card corner rounding machines, in which I use a pivoted knife having a series of curved cutting-edges, suiting different radii of book or card corners, the curved cutting-edges being set at right angles with a base pivoted to a reciprocating knife bar or carrier, and made to adjust around the pivot in the end of the knife-bar, in order to bring various sizes of the curvedcutting-edges into position to out different sizes or radii of book or card corners without removing the knife from .the machine. These objects I attain by the mechanism shown in the accompanying drawings, in which- Figure 1 is a side view of the entire machine; Fig. 2, a top view of the machine on line a: m,- Fig.'3, a top view of the knife as it appears after removal from the machine; Fig. 4, a vertical section of the lower end of the knife-bar, showing the manner in which the knife is secured to its reciprocating bar, together with the method of retaining it in its respective positions of adjustment, like letters referring tov like parts throughout the several views.
The table B, having lug R, fenders O G, and guides D, is pivoted to an adjustable stand, A,
the upper ends of the fenders G 0 being made parallel in order to form a guide or sheath for knife-bar E and self-clamp J to travel in.
1 is the operating-lever, F the knife, L L the books on which the machine is about to com- Inence to cut, and KK K'K the curved cutting-edges.
The machine is made adj ustable to difl'erent angles of elevation by means of pivot-joint P and circular slot and bolt Q, the object of setting the machine at an angle of, say, forty-five degrees being to cause the books or cards to slide partially by gravity into the cutting corner of the machine, and not having to be entirely pushed there by the operator.
The compensatin g-link H is connected with lever I and reciprocating bar E, in order to harmonize the working of lever I with the parallel motions of self-clamp J and reciprocating knife-bar E. Fig. 2 shows the books or cards clamped in the machine with the self-clampJ upon them; also, the shape and uses of fenders O 0, together with the manner in which they guide the books into the cutting corner of the machine. Their upper ends, being made parallel to each other, also at the same time form a guide or sheath for the knife-bar E and self-clamp J to travel in when reciprocated by lever I. g
In Fig. 3 is shown the knife F detached from its bar E, with its series of curved cutting or corner-rouudin g edges K K K K, together with holes for pivot-bolt G and spring stop-pin N.
Theknife F is made as follows: A round flat piece of steel has as many segments or angular pieces cut out of its edge as it is desired to contain cutters. The parts left standing are then bent upward at right angles with their base and grooved out vertically, as shown at K, corresponding to the shapes and sizes of corners to be out, after which their cuttingedges K are sharpened and drilled in the base, with holes for pivot-bolt G and spring stop-pin N, and hardened for use.
The operation of myinventiou is as follows: The books being placed in the machine, as shown at Fig. l, the operator pulls downward on lever I, using self-clamp Jas the fulcrum of his lever, and the corners of the books being under the said fulcrum or clamp J, they are thus clamped according tothe resistance offered by the hooks to the cutting-edge of knife F. Further pressure on lever I will now cause knife-bar E to move upward, carrying with it knife F, with its curved cutting-edges K, thus rounding the corners of the books until it has moved entirely up through the pile of books and brought in contact with bottom of selfclamp J, or fulcrum,when it has performed its work.
It will be observed that the motions of selfclamp J and knife F are always in opposite directions to each other, and that the harder the books are to cut the harder will be the ac tion of self-clamp J, it clamping according to the resistance offered to cutting-edge of knife F, as before stated. It is also plain that differeut thicknesses of books and cards can be clamped and out without any further adjustment of the clamping parts, as the thickness of material to be clamped and cut always reg- 5 ulates the height of fulcrum for the travel of knife-bar E. Thus the thinner the material to be clamped and cut the less will be the movement of lever I, and, again, the thicker the material the greater the movement of le- 10 vet 1.
Having fully described my invention, what I desire to secure by Letters Patent is as follows:
In a machine for rounding the corners of books, &c., the combination, with the pivoted r 5 knife F, having curved cutting-edges K and holes M, of the pivot-bolt G, reciprocating bar E, and spring stop-pin N, adapted to operate as set forth.
