BOOK- HOLDING CLAMF FOR INDEXING PURPOSES SPECIFICATION forming part of Letters Patent N 0. 617,787, dated January 17, 1899.

Application filed May 10, 1897. Serial No. 635,855. (No model.)

To all whom it may concern.-

Be it known that I, SMITH N. WEBB, a citizen of the United States, residing at Detroit, county of WVayne, State of Michigan, have invented a certain new and useful Improvement in Book-Holding Clamps for Indexing Purposes; and I declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to book-indexing, and has for its object a machine adapted to facilitate the cutting of notches in the leaves of books, so that an index character can be printed or placed on'the leaf which forms the bottom of the notch when the book is closed. The machine is intended to be used in connection with an indexing-machine patented to me on the 23d of March, 1897, No. 579,202. It can also be used disconnected from any machine and the cutting done by v hand.

The object of the invention is to provide a holder in which the book to be indexed is prepared and held closely and securely and notched and indexed while so held.

The holder consists, essentially, of a box of peculiar shape and with peculiar adjustments. There are in the box a number of fingers, each of which carries a cutting block or blocks adapted to be placed under the leaves to receive the edge of the cutting-knife and stop it at the proper place. These fingers are arranged to be adjusted and moved in several directions, and are also arranged to take special positions with reference to each other in order that the uncut leaves of the book may not be injured and that the portions out from the leaves may be cleanly and neatly cut away.

In the drawings, Figure 1 shows the holder or box in perspective. Fig. 2 is a plan view of two of the fingers and the cutting-blocks attached to them- Fig. 3 is a section through two of the cutting-blocks and shows the leaves of the book between them and above and below them. Fig. 4 is a perspective showing additional attachments to the box.

Fig. 5 shows an extensible finger in which the cutting-block can be rotated.

A and B indicate the sides of the box, which rise from the bottom 0.

D indicates the back of the clamp. This is hinged to the bottom 0 and rests at an angle with respect to the bottom. The angle between the bottom and the back can be varied to suit the book to be indexed by means of an arched slot at in the side A of the box and the winged nut a, that engages a bolt projecting from the end of the back D.

Each of the sides Aand B is provided with an arched slot similar to the slot at, so that both ends of the book may be firmly held in the desired position. On each of the sidesA and B, near the end to which the back D is attached, is a vertical post 2, and on the vertical post 2 engages a vertical extension-slide 3. One of these parts (as the extension-slide) is provided with a slot or slots vertically arranged, through which passes a holding-screw or holding-screws 8, and the holding-screws engage the other parts, so that together the post 2 and the slide 3 furnish a side standard, the height of which is adjustable. ing pieces 3 is hinged a bar 4, and the top of the other slide 3 is turned at right angles to furnish a rest and a catch. Against the rest the end of the bar engages, and under the catch a spring-hook 5 on the end of the bar 4 engages.

The book tobe indexed is placed in the box between the standards, the standards adjusted to the proper height, and the bar turned down over the top of the book after the cutting-blocks have been placed in position. If the indexing is done before the book is bound, a broad bearing-plate is preferably used under the bar.

In each side of the box, at that end which is farthest from the back D, is a vertical slot or two or more vertical slots, and on the inside of each side Aand Bis a track-bar, held by screws passing through'the slots. In the box shown in the drawings there are on each side two track-bars. The number of them would depend on the number of banks of knives that are used in the indexing-machine, as some machines may be used with one bank of knives and others with two or more banks To the slidthe screws 5 and 5.

of knives. The box shown would properly be used with a machine having two banks of knives.

The track-bars 5 and 6 are arranged in pairs. The track-bar 5 is paired with a cor responding track-bar that is on the inner face of the side A and is held up in position by- The track-bar 6 would be one of a pair the other member of which is held up by the screws 6 6 On each pair of track-bars engage loosely the runners of a frame that carries the fingers and cutterbloeks. 5 indicates one of these runners, and its companion runner is concealed behind the side A. The runners are joined by a cross-bar that serves as an axle for the fingers. On the bar 5 are hung a number of fingers 7 7 7 7, and these fingers are properly spaced along the bar 5 between suitable sleeves S 8. To each finger is jointed an extension. For example, to the finger 7 is connected by a hinge-joint an extension 9, and to the finger 7 is connected by a hingejoint an extension 9. At the free end of the extension 9 is secured by pins or in any suitable way a broad plate of some material suitable to act as a cutting-block. Such material may be brass, copper, or preferably vulcanized fiber; but any material similar to these may be employed.

Each cutting-block 10 10, &c., is somewhat wider than the space from center to center between adjacent fingers, and the two contiguous edges of adjacent cutting-blocks overlap, and each cutting-block preferably has its edges beveled both on the upperand lower side, so that the extreme edge of each block is quite thin and knife-like. The object of this form of construction is. to prevent the cutting or tearing of leaves that may be between adjacent blocks, especially when it is necessary to use the blocks so disposed in the book that there is only a single or very few leaves between them. Unless the edges of the blocks overlap they would be apt to shear the leaves, and unless the edges were beveled the gouge might sometimes shear the leaves at improper places; but with these overlapping and beveled blocks the leaves will not shear under any pressure which can be brought to bear in cutting the notches.

The adjustable track-bars enable me to change or adjust the relative height of the two ends of the bar or axle 5 to conform to the size of the book to be indexed, and the hinged finger, with its two parts 7 and 9, permits the cutting-block 10 to assume a horizontal position, or such position that the leaves and the pressure on the leaves may render necessary, whether the block be in serted on a level with the bar 5 or above or below it. The several fingers shown in Fig.

1 indicate the position that will be assumed by the several cutting-blocks when placed in the book.

To use the box, the book is placed in position, and the cutting-blocks are also placed against the front edge of the book.

in the box, with the-runners on their tracks, but with the end joints 9 '9, &c., thrown back. The book is opened to the last one of the pages that the index character is to be printed on and the first or lowermost of the cutting-bloeks dropped into position. The leaves of the book areclosed over this bar until the page of the next to the last index character is reached and the second cutterblock is dropped into position, and so on until all the cutting-blocks have been dropped into position. If more than a single bank of cutting-blocks is used, the operation of placing the second one is precisely similar to that of placing the first. After all the cutting-blocks have been placed in position the cover of the book is closed down (or if not yet bound a bearing-plate is placed over the book) and the bar 4.- swung over and caught, and as this bar iis so adjusted that it bears with considerable pressure on the top of the book when it is closed down the parts are held in position with sufficient pressure to cause them to stay securely in place. The box, with its prepared book, is now ready for the cutter and printer.

In Figs. 4 and 5 are shown other attachments which are sometimes used to hold the book in the clamping-box. These consist of a movable back in place of the hinged back and of adjustable front fingers orelamps that rest The sides 22 22 and the bottom 23 of the box are made longer toward the rear than are the sides and bottom of Fig. 1, and the back support 24 is adjusted to any angle and arranged to slide along the bottom of the box and to be held in its finally-adjusted position by means of the thumb-nuts 25, which engage on the ends of bolts that reach from the back-support 24: through slots 26. The back-s u pport 2 iis held firmly in its adjusted position by a brace 27,

engages a thumb-nut on the outer .side of the box. The finger 29 is adjustable along the axis of the rock-shaft 31, so that it may be used with a book that is shorter from top to bottom than the width of the box. The cutting-blocks are mounted on round stems 34, and the round stems engage in tubular joints 35 of the hinged fingers, thus enabling the cuttin g-block to assume its proper position irrespective of the angle at which the hingebar is set, and also enables the workman to adjust the cutting-block independently of the hinge-bar, so as to vary the length of the entire finger somewhat, if he. desires to make that adjustment.

As most books will be indexed before the stiftboards of the cover are placed upon them, it is advisable generally to have the surface of the clamp-bar f broad enough to cover most of the upper or first leaf of the book; or the same result may be attained by using with each book that is indexed a stiif plate above the book and under the clamp-bar.
