PRlNTERS BLOCK.

Specification of Letters Patent.

'Eatented June 12, 1906.

' Application filed July 31,1901. Serial No. 70,318.

My invention relates to printers blocks or hooks for holding stereotype and other print.

and it has for its primary ob3ect to provide a rinters block of such construe tion that t e nut or turning head provided for the application of the wrench by which the movement of the hook relatively to the plate is effected may followthe hook back and forth, whereby much less s ace back of the hook for the manipulation ofthe turning head will be re uired and the screw may be rigidly fixed and therefore require much less material for its bearings at o posite ends thereof and as a consequence alibw the hook to approach much closer than heretofore the edge of the block. I

With these ends in view my invention consists in certain features of novelty inthe construction, combination, and arrangement of parts by which the said objects and certain other ob'ects hereinafter appearing are attained, afl as fully described with reference to the accompanying drawings and more particularly pointed out in the'claim's.

In the said drawings, Figure 1 is a side ele ing plates;

vation of my improved hook, showing the.

printing-plate in dotted lines. F'i 2 1s a lan. view thereof, showing the hoo r at the imit of its retracted movement. Fig. 3 is a similar view showing the hook advanced.

Fig. 4 is a vertical longitudinal section taken on the line 4 4, Fig. 2. Fi 5 is a similar section taken on the inc 5 5, Fig. 3. Fig. 6 is an Fig. 7 is a cross-section taken on 4; and Fig. 8 is a similar section taken on t eline 8 8, Fig. 4.

1 represents the block proper, which may be composed of a solid block of metal or any other suitable material or constructed in any other manner so lon as the upper side thcrcof be provided fwit a longitudinal slot 2, which extends from a point near one end of the block 1 entirely through the other end and below this slot is formed a cylindrical cavity 3, also extending from a point near one end of the block entirely through the other end view;

provided with a dovetai end, the cylindrical cavity 3 being of greater diameter than the width of the slot 2, as better shown in Fig. 7, so as to accommodate a round nut or turning head 4 and permit the latter to move back and forth along the cavity 3, but hold it against vertical movement through the slot 2. The nut or turning head 4 is provided in its outer face with radial wrench sockets or grooves 5 for the application of a pin or other suitable .wrench whichis passed downwardly throughjthe slot 2 just back of the hook 6 in the usual manner, and said nut or turning head is threaded on a screw 7, which has its threaded extremity supported in a removable plate or disk 8 and its eaded end 9 supported in a suitable counterbore in the opposite end of the block 1, as clearly shown in Figs. 4 and 5. The disk or plate 8 has threaded connection with the screw, so that by tightening, the screw the disk will be drawn firmly against the end of block 1', which is recessed or inortised, as shown at 10, Figs. 4' and 5, for receiving the disk and holdin it flush with the end of the block, and in order that the disk may not rotate with the screw the upper edge thereof is 11 projecting upwardly therefrom and being sheercd off flush with the upper face of theblock, as shown in Fi 6, and seated in a corres ondin dovetail mortise 12 in the' end oft 1e bloc said dovetail mortise 12 being constituted by bevelin the edges of slot 2 throughout a portion of their length, or so much thereof as is traversed by nut bevel ma perform the further useful purpose of a lowing the wrench or turning key a greater range of movement in either direction. The screws 7 also constitute a guide and support for a slide 14, upon which is formed or secured a shank 15 of the hook; but this slide has no threaded connection with the screw and is held firmly against the nut 4 and caused to follow said nut during its re ceding movement by means of a coil-spring or other suitable cus ion 16, sleeved on the screw 7 between the slide 14 and the inner end of the cavity 3. The hook and slide are caused to move in the opposite direction for gripping the plate by the nut 4, as will be understood. In order that the nut may not be deprived of any of its bearin r upon the screw 7 and at the same time may c-as thin as possible at its outer edge or periphery for per- 4, as shown at 13, so that the a consequence the disk or by statin .this construction it will be seen that inassary for the insertion qluence a second 2 saeie,

1. In a-printers block, the combination of a block proper having a recess opened through the top and through one end, a disk closing the said end of the recess, a screw projecting mittin the hook 6 to come as close tov the end of the %lock as possible, the back of the hook and shank are let into the inner face of the nut or turning head, or it might be described that the inner end of the nut is let into the s ank so as to underlie the hook, as

mg one end bearing in the block proper, and shown at 17 in Figs. 4 and 5. By means of the other end threaded in said disk, a hook projecting through cess, a slide sleevedloosely on said screw and supporting said hook, a spring sleeved on said screw between said slide and one end of the block proper, head located on said screw between t he'other side of said slide and said disk, substantially as so; forth..

2. In a printers block, the combination of a block proper having a recess, a screw secured in said recess, a slide on said screw, a hook on said slide, a turning head threaded on said screw cont'i uous to said slide and hook, said turning ead being let into the back of said slide and hook whereby the hook will overlie the turning head and a s rin for pressing the turning head against t substantially as set forth,

JOHN KYLE.

much as the turning head follows the hook the space-required bacl; of the hook need at no time be great 1' than that which ls necesof the wrem 1 into the sockets in the turning head, and as a cons plate may be placed much oser to the back of the hook than hereto- It will also be seen that the screw 7, being striionary, it does not require extended bearings at its ends for its support, and as plate 8 by being composed of steel may be made comparatively thin, and tI-erefore the entire distance between the end of the blockthat is, the outer edge or face of disk 8 and the back of i hook 6need only be suflici t for the ac- I commodation of the thickness of the disk and the sockets 5 in back of the turning head.

Having thus described my invent 11, what I claim as new therein, and desire to secure by Letters Patent, is-
