PRINTER/S HOOK.

Application filed December This invention relates to improvements in the art of printi'ng,and the primary object is to provide a simple,-practica l and highly efiicient construction of so-called hook, or look, the same having'for its'object to engage and lock printing plates upon expancommonly employedin filling in the spaces in a printing chase. Further and 'more specific objects will be disclosed in the course of the following specification, reference 'being had to the accompanying drawing,

wherein:

Fig. 1 is a perspective'view of my improved locking hook.

Fig. 2 is an enlarged top or plan view of the hook shown in Fig. 1.

Fig. 3 is a sectional view as on the line 3-3 in Fig. 2.

Fig. 4 is a sectional elevation as seen substantially on the line 4 et in Fig. 3.

Fig. 5 is a perspective view of the guide or follower employed.

Fig. 6 is a perspective view of one of the side sections. 7 v

Fig. 7 is a planview of a portion of a printers chase or frame in which are ar ranged and secured a number of my 1mproved plate hooks.

Referring to the drawing more particularly and by reference charactersA designates a frame or chase in which is arranged and locked the usual filler blocks B which are customarily employed to fill in the nonprinting or blank spaces between the type. It is often necessary, in setting up a page or printing unit, to use as a part or parts thereof electro and other process plates C and D, which are frequently employed for color work, such as job and book work, publications, catalogs, etc., and, as the printing surfaces of these plates must be flush or even with the printing surface of the type they are necessarily very thin,'as the top surfaces of the blocks B are flush with the top edges of the type blocks.

My object, therefore, is to provide a practical method for securing the plates on the blocks B, and this I accomplish by substituting for certain of said blocks, depending u on the size, location and position the plate is to assume, a series of hooks or looking blocks E, the construction of which may be described as follows:

Each block E comprises a substantially U-shaped end and bottom member 8, to and 7; 1925. Serial No. 73,677.

in which is rigidly and securely fastened, as

by rivets 9, a pair of side sections or members IQ and 11, so that the members 8, 10 and 11 forma substantially solid'block having a central slot oraperture 12. v The sided members 10 and 11 are providedin their inner surfaces with directly opposed horizontal grooves 13 and 14-, and diagonal slots 15, A follower member 16, consisting'of a rectangular block, is slidably arranged in the slot 12 'and'is provided with opposite diagonal flanges 17 adapted to move or slide in theinclined grooves 15. The follower is provided with central threaded hole 18, in which screws a bolt 19 having a key-hole 20 in which a key may be inserted to turn the bolt. The bolt 19 is further provided at its lower end and near its upper end with a pair of rigid circular flanges 21 and'22, which respectively engage and rotate in the grooves 14 and 13, and thus prevent any play or tilting or tipping action of the bolt in'the slot 12, allowing it to move only longitudinally of and in the slot.

Rotatably secured upon the upper end'of the bolt 19 is a gripping member or jaw 23, the same being provided with an undercut or bevelled edge 24 for gripping engage ment with the edge of the plate G or D. The object of rotatably mounting the jaw on the bolt is, first, to allow the bolt to rotate, and second, to permit the edge of the jaw to engage the plate evenly even when the plate edge is at a considerable angle from the horizontal or vertical. As shown in Fig. 7 the plate edges are parallel with the sides of the chase, but it is frequently desired that a plate be secured in an angular position, with its edges running obliquely to the sides of the chase, and in such instances it is obvious that the members 23 will squarely engage such edges even though the blocks E are square with the chase.

It is understood that various modifications may be made in the general design and structural details of my invention, as herein disclosed, provided, however, that such modifications come within the spirit and scope of the appended claims.

Having now therefore fully shown and described my invention what I claim to be new and desire to protect by Letters Patent is: Y

1. In a device of the character described,

a block having a rectangular recess provided ways and horizontal guideways, a follower adapted to be guided by said inclined guideways, a bolt threaded in said follower, and having flanges for engagement in said horizontal guideways, and a jaw member adapted to be moved over the face of the block by Said bolt. 7

2. In a device of the character described, a block having a rectangular recess provided in its walls with horizontal grooves, a vertical bolt having circular end flanges arranged to rotate and move horizontally in the grooves, a jaw carried by said bolt, and means for moving the bolt horizontally by rotating the same. p

8.111 a device of the character described,

ablock having a rectangular recess provided in its walls with opposed inclined and horizontal guideways, a vertical bolt in-said recess adapted to be held against vertical movement by circular flanges operating in;

said horizontal guideways, a follower, en-

gageable with the inclined guideways tox "in its walls with opposed inclined and horizontal guideways, a vertical bolt in said recess adapted to be held against vertical movement by flanges operating in said h'orizontal guideways to move the bolt in a hori-; zontal path when the same is rotated, and a plate engaging jaw rotatably carried by the upper end of said bolt I V In testimony whereof I affix my signature.
