' 1'0 ail whom it seam-a.-

' vention, I employ a rack, desirably in the Be it known that I, WALLACE S. WAR- NOCK, a citizen of the United. States, resid ing at Chicago, in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in Printers Registering Devices, of which the following is a full, clear, concise and exact description, reference being had to the accompanying drawings, forming apart of this specification.

My invention relates to registering devices for printers use and has several obects.

Hitherto the market has been supplied with printers registering deviceseach provided with adjusting means engaging the back of the hook base by a follower or adjuster; or some other construction has been employed extraneous to the traveling hook element that would force the travel of said element to secure its clamping action upon the plate to be held. It has hitherto been the practice also to provide each hook element with but one surface to engage a plate, so that the hook element in order to effect its clamping action was limited to a single direction of movement. If the registering .devices were not so disposed as to engage 3'0 the plates they were to clamp, the entire registering devices would have to be taken out and reversed in position.

In practicing my invention, I have constructed a registering device wherein the adjustment effecting means is not extraneous -to the traveling element of the device but is carried-thereby, so that the registering de vices may be made small and compact, and.

which will permit of a very close approach of the plates that are to be held in position.

The device of the preferred formof my invention also includes as the engaging ele ment of the traveling moved in one direction, may engage one plate, and, when moved in another direction, may engage another plate, whereby a printers form equipped with the devices of my invention may be quickly assembled without the removal and repositioning of the registering devices.

In the preferred embodiment of my inook structure, doub e jaws, so that said hook element, when form of a threaded screw normally station ary and mounted at its ends in the walls of a suitableblock, the base of the register hook carrying train "ear elements that cooperate with said rac one of said elements being accessible desirably through the body of the hook, whereb the entire traveling hook structure may he moved. The train gear elements carried by the traveling hook structure are desirably a worm wheel in engage'ment with the rack and a worm shaft,

which is the element that is made accessible to a suitable operating tool.

I will explain my inventionmore fully by reference to the accompanying drawing, showing the preferred embodiment of the invention, in which Figure 1 is an isometric view of a StIHO ture embodying the preferred embodiment of the invention. Fig. 2 is a plan view thereof. Fig. 3 is a longitudinal sectional view on line 33 of Fig. 2. Fig. ff is a cross-sectional view on line 4-4 of Fig. 2.

Like parts are indicated by similar characters of reference throughout the different figures. I

The block a is made hollow and forms a separable part of a plate foundation, being provided with four vertical walls between which there is a vertical space clear through the block for cheapness o construction and to afford the desired operability of the traveling hook element. The lateral vertical walls are provided with lips I) at the upper margins thereof, between which the reduced top portion of the base 0 of the hookis dis-p 'posed, the lips I) being the only portions of the block that desirably engage the base of the hook, clearance being afiorded between the balance of the base of the hook and the block so as to eliminate as much friction and binding action as possible. The rack d is preferably in the form of a screw that is held intoplace by the screw 6 (Fig. 3), and which has a cylindrical enlargement f resting in a wall of the block, this head bein screw slotted at g, so that if the surface 0 the horizontal rack d engaging the worm' Patented Oct; 31, 1911.

wheel h to be hereinafter described, should become worn, thescrew d may be turned sufliciently to present a new working rack surface to the wheel 71..

The base 0 of the register hook is longitudinally channeled to permit the screw (Z to pass therethrough, the outer diameter of the screw closely fitting the channel, so that said screw and the lips b may cooperate to define the travel of the element a.

' The worm wheel h is provided with a shaft, upon and with respect to which the worm wheel it rotates. This shaft has a reduced portion 11 that it screwed into the base 0 and an enlarged screw-driver-headed end is desirably having a journal in the element 0, so that said shaft may be maintained in suitable alinement. .This shaft, while remaining stationary, permits the wheel h to rotate freely thereupon, this Wheel having an axis of rotation transverse to the direction of travel of the register hook. A vertical worm shaft Z engages the wheel h and is provided with a square recess m, as indicated most clearly in Figs. 2 and 3, into which a suitable square ended tool may be inserted for effecting the rot-ation of the shaft Z. ,The hook element 12 is provided with an aperture through which the operating tool may find accessto the recess m. The hook n is desirably, though not necessarily, separably secured to the base 0, and, if it is separably secured to said base, such separable connection is desirably a threaded connection, whereby the base and hoop may be readily connected together, while at the same time suitable motion of the hook is permitted.

It will be seen that the horizontal depth of the hook, that is, that depth transverse to the plate engaged by the hook, may be made very shallow whether the hook is provided with one or two jaw portions pp. I prefer to employ two jaw portions for the hook, for this construction will readily enable me to engage a plate lying on either side of the hook, without the necessity of withdrawing the registering device from the form and reversing its position. The advantage of this construction'is illustrated in Fig. 3, where two plates 9 are disposed upon opposite sides of the hook.

It will readily be seen that by rotating the shaft Z in one direction, one plate 9 may be engaged by the hook, and that when the direction of rotation 'of said shaft Z is reversed the other plate 9 will be en gaged by the hook--all without removing the registering device from the form.

It will be seen that the shaft Z has a vertical axis of rotation and the wheel 1' a horizontal axis of rotation transverse to the axis of rotation.

An important advantage gained by the structure herein disclosed resides in the locking action that I secure, for it will be seen that the wheel k can only be rotated by the shaft Z and that this shaft Z locks the 1 and advancing the register hook in either direction. This lock is a positive one that will serve to prevent the hook from receding from any position irrespective of the direction in which said book has been moved.

It will be seen that I have provided a clamp device for holding printing plates to a grooved bed or foundation, comprising a body portion apertured in different directions and provided with a recess in one side, a rack bar passing through the body in one aperture and along which said body is movable in oposite directions, a worm shaft in the other aperature and a worm wheel in the side recess meshing with both the worm shaft and rack bar.

I do not wish to be limited to the precise construction shown, but,
