VILLIAM BRAIDVVOOD, OF MOUNT VERNON, NEV YORK.
VCORNER-CUTTER FOR BOOKS.
SPECIFICATION forming part of Letters Patent No. 391,681, dated October 23, 1888.
Application filed August 4, 1867.
To ctZZ whom it may concern.-
Beit known that I, WILLIAM BRAIDWOOD, a citizen of the United States, residing at Mount Vernon, in the county of Westchester and State of New York, have invented new and useful Improvements in Corner-Cutters for Books, 85e., of which the following is a specification.
This invention has for its object to provide novel and efficient means for cutting the corners of books, pamphlets, and similar articles; and it consists in the'features of construction and combination of devices hereinafter described and claimed, reference being made to the accompanying drawings, in which- Figure l represents a front elevation of a machine embodying my invention. Fig. 2 is a vertical section thereof in the plane x x, Fig. 1. Fig. 3 is a transverse section in the plane y y, Fig. 1. Fig. 4 is a similar'section in the plane .e z, Fig. 2. Fig. 5 isaperspective View of a book as cut by the machine.
Similar letters indicate corresponding parts.
In the drawings, the letter A designates a frame for sustaining the operating parts of the machine, which frame is provided with a laterally-extending portion, A, that can be secured to a suitable bench or support, A2. In the upper portionof this frame are located boxes b b, which form bearings for a horizontal driving-shaft, B. A rotary motion in the direction of arrow l, Fig. 2, is imparted to said shaft by means of a tight pulley, C, located on one end of the same, which pulley is connected, as usual, by a belt to a countershaft. (Not shown in the drawings.) A loose pulley, U', is provided, upon which the belt can be shifted when it is desired to discontinue the motion ofthe driving-shaft B.
To allow the machine to be operated by hand,a square head or post, c, Fig. 1, is formed on the opposite end of the driving-shaft, which is received by a suitable socket in an ordinary crank. (Not shown.) Ator near the central portion of the driving-shaft B is located a fixed cam, D, which is in .position to engage with a. roller-stud, D', the shaft of which has l bearing in the upper slotted end of a spindle,
which I shall hereinafter call the carrier77 E. This carrier E is movable in the direction of its length in a suitable box, f, extending from the frame A, and it is prevented from turning about its axis by an arm e, Fig.
2, which extends laterally therefrom and ensefial No. cimas. (No model.)
gages a slot or guide groove, e', in the frame A. The lower end ofthe carrier E is recessed to receive a piercing or separating devicesuch as the cutter F-which is removably secured thereto by bolts f. The lower portion of the cutter is suitably shaped and rounded, as usual, to form on the book B, Fig. 5, such a corner as illustrated. The book-receiving table G is located beneath the cutter F, and is provided with a slide, H, of soft material-` the end of the slide I-I under the cutter becomes worn with use, the slide can be removed and reversed, so as to bring its fornier outer end under the cutter.
To effect the adjustment of the table just explained, the table G is provided with a pendent portion, g, which lies close to a vertical portion of the frame A, and contains a vertical slot, g', through which extends a setscrew, 7L, by which the table can be clamped iirlnly t0 the frame. An adjustingscrew, h', engaging an internal thread in a horizont-al portion of the frame, bears against the lower end of the pendent portion g of the table G. By the use of this adj Listing-screw h the table can be adjusted very accurately with relation to the cutter F, and subsequently fixed in position by the setescrew h. Other wellknown devices can be used for adjusting the receiving-table in place of that just described.
Ou the uppersurface of the table are secured oblique gage-pieces I, which are placed to form a right angle with each other, but do not meet. These gagepieces are so arranged with IOO 2. @greci working stroke by a retracting device, such as a stout spiral spring, J, one end of which is attached to the upper portion of the frame at]l and the other end to a pin or projection, j', extending from the lower end of the carrier E.
The cam D (see Fig. 2) is segmental in form, and its contour is so shaped that in the rst half of each revolution of the driving-shaft B it moves the cutter-carrier E toward the receivingtable G to the full extent of its stroke, immediately after which the carrier is released from the cam, and is instantly moved in adirection away from the table by the action of the spring J. During the remaining portion of each revolution of the driving-shaft B the carrier E is motionless,and the cutter F is held above the receiving-table and out of the way of the operator, so that a new book can be properly placed on the said receiving-table. To hold the book firmly upon the receiving` table and to compress the leaves thereof, I make use of a presser-foot, 7c K. The vertical shank k thereof is guided at one end in a lug, Z, Figs. l and 2, extending laterally from the top of the carrier E, and at its other end in a lug, Z', extending laterallyfrom the lower end of the carrier. A spiral spring, L, encompassing a portion of the shank k of the presser-foot, is confined between the lug Zand a pin or other projection, m, extending transversely through the shank 7c. This spring L consequently connects the shank k of the presser-foot with the carrier E.
The foot K,secured to shank k,is set slightly in advance of the lower end of the cutter. Zhen the carrier E moves toward the table, the presser-foot K k is carried therewith and in a direction parallel thereto, since the lug Z on thccarrier acts on the pin m through the medium of the spring L. The foot K comes into contact with the book prior to the cutter F. Its motion is thereby arrested and it holds the book irmly down to the receiving-table G. -As the cutter F descends in its cuttingstroke, the pressure of the foot K on the book increases, since the spring L is compressed more and more during the said cutting-stroke. The presser-foot returns with the cutter-carrier in the non-working stroke.
To adjust the lead of the presser-foot K relatively to the cutter F, a number of holes, n n, Fig. 2, are formed in the length of the shank k of the presser-foot, through which the pin m can be inserted, and since the `spring L continually holds said pin in contact with the lug Z the normal position of the presser-foot varies according to the position of the pin.
It is evident that the carrier E can be constructed to hold a punch or cutter of any variety to adapt the machine for any particular purpose, and therefore the function of the machine is not restricted to cutting books and covers.
The retracting device J may consist of a weight attached t0 the carrier by a cord or chain, or by a lever, such being a well-known equivalent of a spring.
What I claim as new,and desire to secure by Letters Patent, is
l. Amachine for cuttingbook-corners, combining in its structure a frame, A, having a book-table, G, provided with gage-pieces I, a vertical carrier-spindle, E, having a cutter, F, and guided on the frame, a spindle-retracting spring, J, and a horizontal revolving shaft, B, journaled on the frame and provided with an attached revolving segmental cam, D, disconnected from the spindle and acting thereupon in one half-revolution of the sha ftand away from and inactive on the spindle in the other half-revolution of the shaft to permit the spindle to remain motionless for a limited time after it has been retracted by the spring and while the revolution of the shaft and cam continues, substantially as described.
2. A machine for cutting book-corners, combining in its structure a frame, A, having a book-table, G, a vertical carrier-spindle, E, guided on the frame, and having the rollcrstud D at its upper end, and cutter F at its lower end, a spindle-retracting spring, J, and a horizontal revolving shaft, B, journaled on the frame, and having an attached segmental cam, l), disconnected from the spindle and acting thereon in one half-revolution of the shaft and away from and inactive on the spindle in the other half-revolution of the shaft to permit the spindle to remain motionless for a limited time after it has been rctracted by the spring and while the revolution of the shaft and cam continues, substantially as described.
3. The combination, with the reciprocating cutter-carrier, of the presser-foot K, guides Z Z for the saine formed on the cutter-carrier, and an independent spring, L,connected with the presser-foot and the carrier, substantially as shown yand described.
et. The combination, with a reciprocating carrier, of the presser-foot K, having a shank extending parallel with the carrier, guidesZ Z for the shank projecting from the carrier, a spiral spring, L, encompassing the shank, and confined between the guide Z, and an adjustable pin, m, substantially as shown and described.
5. The combination, with a vertically-adjustable receiving-table, and gage-pieces I, secured thereon at right angles to each other, of a movable cutter-carrier, a pressenfoot, having a spring connection with the carrier, and means, substantially as described,for actuating the cutter-carrier, substantially as shown and described.
In testimony whereof I have hereunto set my hand and seal in the presence of two subscribing witnesses.
