PLATE-HOLDER.
Specification of Letters Patent.
Patented Apr. 9, 1912.
Application filed March 1, 1911. Serial No. 611,667.
To all whom it may concern.
Be it known that I, FREDERICK L. SOHLEY, a citizen of the United States, and a resident of the city of New York, borough of Manhattan, in the county and State of New York, have invented a new and Improved Plate-Holder, of which the following is a full, clear, and exact description.
This invention relates to a new and improved holderfor securing in position plates of varying sizes.
It has been found in practice that where slots are provided, or other means for supporting a printing plate to allow for the adjustment of the members securing the plate in position, under the great pressure to which the plate is exposed in the press, it sinks into its slot to a greater or less degree, thereby lowering the surface of the plate at this point, and making the impression at this. point fainter than at the remaining portions of the plate. An object, therefore, of this invention is to provide means for holding plates of various sizes, which can be adjusted without leaving any openings or slots into which the plate can a further object of this invention is to provide a device which will be simple-in construction, inexpensive to manufacture, strong, durable, and easily adjusted.
These and further objects, together with the construction and combination of parts, will be more fully described hereinafter and particularly set forth in the claim.
Reference is to be had to the accompanying drawings forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the views, and in which Figure 1 is a top plan view of a block having my particular. form of adjustment therein; Fig. 2 is a side View in elevation,
partly in sect-ion to show the underlying structure; Fig. 3 is a detail vertical section through one of the adjusters; Fig. 4 is a detail vertical section showing one of the worms; and Fig. 5 is a vertical section on the line 55 of Fig. 4.
Referring more particularly to the separate parts of this invention as embodied in the form shown in the drawings, 1 indicates a block, of a type adapted to receive a plate and which may be provided on two juxtaposed sides with elongated hooks or retainers 3 and 4, which may be of any suitable form, such as plates provided with an overhang at the upper end, as indicated in Fig. 2. The plate to be secured on the block can be forced up against the retainers 3 and 4 and held from movement in two directions. In order to hold plates of varying sizes, there are provided one of more hooks 5, 6 and 7, mounted on adjusters 8, which are capable of movement so as to bring the hooks into closer juxtaposition with the retainers 3 and 4. These adjusters 8 may be of any suitable character, but in this instance are shown as being in the form of cylindrical members 9, rotatably mounted in the block 1 and having their upper surfaces flush with the upper surface of the block, so as1 to'leave no depression, openings, or the li (e.
Each of the adjusters is provided with a worm wheel 10, which may be separate and connected to the adjuster, or formed thereon as indicated in the drawings. Engaging each of these worm wheels, there is provided a worm 11, which is rotatively mounted in the block 1 and prevented from endwise movement in any suitable manner as by means of a lock 12 engaging a circular slot 13 in one end of the worm, The worms may be rotated in any suitable manner, as by means of mechanism engaging a gear 14, secured to the end of each worm. In this instance, the gears 14 which manipulate the hooks 6 and 7 are shown as being operable in unison by means of a rack 15. The rack 15 may be held in position by guiding clips 20, which may be secured to the side of the block 1 in any suitable manner, and are adapted to overhang the top of the rack. These guiding clips maybe of any suitable number, arranged at suitable spaced intervals.
In order that the hooks which are shown as being capable of engaging the plate at more than a single point may always extend parallel to the retainers 3 and 4, they are adjustably connected to the adjusters 9, so as to automatically adjust themselves to different positions. While any suitable means of adjustably connecting the books 5 to 7 relative to the adjusters, may be used, I have shown in this instance the hook may be enlarged, as shown. At any rate, its upper surface is preferably flush with the upper surface of the adjuster and with the block.
The utility of the device will be readily understood when taken in connection with the above description. The printers plate to be used is placed on the block so that two of its edges contact closely with the re tainers 3 and a. The adjusters 8 are then rotated either singly or simultaneously until the hooks 5, 6 and 7 come in close contact with the edges of the plate. It Will be seen that inasmuch as the hooks are movably mounted relative to the adjusters, they will .assume a position parallel with the retainers 3 and with the edges of the plate, if said edges are parallel to the retainer.
It will thus be seen that there is provided a simple and eflicient means for securing plates of various sizes, without danger of having unevenness in the printing when the plate is put in the press, and which will be exceedingly simple and inexpensive in character.
lVhile I have shown one embodiment of my invention I do not wish to be limited to the specific details thereof, but desire to be protected in various changes, alterations and modifications which may come within the scope of the appended claim.
Having thus described my invention, I claim as new and desire to secure by Letters Patent The combination with a block having one or more openings therein, of a pair of plates disposed at right angles to each other and secured to adjacent sides of said block and having overhanging portions adapted to form retainers, to secure a plate on said block, an adjuster entirely filling each of said openings and having its upper surface flush with the upper surface of said block, a hook rotatably mounted on each of said adjusters, each of said adjusters having a worm wheel connected thereto, a worm engaging each of said Worm wheels, a gear secured to each of said worms, and a rack adapted to engage a plurality of said gears, so as to simultaneously manipulate a plurality of said adjusters.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
FREDERICK L. SCHLEY.
