The body is constructed of two parts, the intermediate portion (6 and the back plate (fl as indicated in the section Fig. 2, which is taken on the line a; m of Fig. 3. For convenience of construction the parts of the box may be made from printers brass rules, which are supplied on the market in accurate sizes. Thus to make the box A we may take a rule, say, six points thick and machine it out, as shown in Fig. 7, presenting the recesses a? and a", and to the back of this we secure by dowelpins (4 the back (0 which is a plain flat rule of, say, three points thickness. The coverplate a may likewise be made from a plain flat rule of, say, three points thickness having openings a to register with the dowelpins (1 and an opening ((7 to receive a screw (5, adapted to extend into a threaded hole a. in the intermediate body. hen such box is together, it is with the dimensions given twelve points in thickness and is adapted to justify at once with any point system of furniture.

The hook is designated B. It is formed, preferably, as shown in Fig. 5, having its upper edge inclined or overhanging, as at 7), and having below one or more projections or legs inclined on their upper surfaces. There are preferably two of these projections, 7) and 7), as shown in Fig. 5. In use these projections enter the recesses a (f in the box, and then when the hook is shoved toward the left of the box in Fig. 7 the inclined upper surfaces of the legs I) and engage with the inclined lower surfaces o and a", carried by the box. Therefore the hook is drawn snugly down into place. In its lowermost position the base of the legs 7) and b engage the base of the recesses a and a", as appears in Fig. 3.

To hold the hook within the body, we provide a suitable lock, which is preferably a wedge, as shown in Figs. 3 and 6. This wedge (designated C) occupies a portion of the recess a and bears against the adjacent edge of the hook B, whereby as the wedge is forced downward into the box the hook is forced along the box and locked thereto. Notches 7) and 0 in the hook and wedge, respectively, allow their convenient removal by any suitable tool.

Owing to the cooperating inclines in the box and the book, there is considerable leeway in the vertical position of the hook, de pendent upon the amount of overlapping of the cooperating inclines, which is varied by the lateral positions which the hook may occupy. The wedge is inserted to a position which takes up the lateral space which the hook leaves between its end and the proximate end of the box-recess. The recess (0 is preferably extended downward at the extreme end to give the wedge leeway. The wedge may thus clamp the hook tightly and the hook clamp the plate tightly, though the hook does not reach its extreme setting position, and thus the plate does not have to justify perfectly on its base.

In use the plate N is laid upon the sectional base, (indicated by P,) with a stationary hook Q at two of its adjacent sides. On the opposite sides our hooks are employed, and the whole is locked in place by the usual furniture, wedges, &c. If it is desired to underlay the plate, (which can only be discovered after the form is on the press,) the wedges C and the hook ID are simply withdrawn. This allows the removal of the plate N without disturbing the rest of the form. Another plate may be substituted for the plate N with equal facility and without interfering with the registration in any manner.

It will be seen that our clamping device takes up very little room, (as heretofore stated, it may very conveniently only require twelve points of space,) allowing the setting of other plates or type as close to the plate as desired. If it is desired to employ plates adjacent to each other with a very narrow margin between them, the same hook may be used to hold the adjacent edges of the two plates. The point of the hook would then be made double, as indicated at I) in Fig. 8.

We claim 1. A printers plate-hook comprising a narrow vertical box, a hook portion consisting of a vertical plate adapted to enter a recess in said box and having an overhanging upper edge, the hook and box having cooperating inclines, the incline of the hook being adapted to take beneath the incline of the box, and means for holding the hook within the box, substantially as described.

2. In a printers plate-hook, in combination, a box having a vertical longitudinal recess extending downward and then under an inclined projection, with a hook adapted to occupy such recess and having a correlatively inclined projection, and means for forcing the hook longitudinally within the box and thereby locking the plate, substantially as described.

3. In aprinters plate-hook, in combination, a body adapted to be locked in a printers form and having a recess opening upward, a hook adapted to occupy such recess, and means for locking the hook within such recess by moving it longitudinally within the body, and a vertical wedge adapted to occupy the recess in said body left vacant by said longitudinal movement, substantially as described.

4. In a printers plate-hook, in combination, a narrow body having a longitudinal recess therein, a removable cover secured to the side of said body, said body being adapted to be locked in a printers form, and a hook snugly occupying the recess in said body and being retained therein by said cover, substantially as described.

5. A printers plate-hook comprising a box,

a hook, and a lock therefor, the box consisting of an intermediate recessed plate, and a pair of flat plates on opposite sides thereofthe hook consisting'of a plate-adapted to snugly occupy the recess between said fiat plates, and the lock consisting of a wedge, also adapted to occupy such recess and force the hook longitudinally, the hook and intermediate platehavinginterlockingprojections, substantially as described.

6. A body adapted to be locked in a print ers form, and having a vertical recess which divides into two recesses a and (0* which have overhanging inclined surfaces a and 0 combined with a hook B adapted to enter said recess, and having legs 6' b with inclined upper edges adaptedto engage the surfaces o a, substantially as described.

7. In a printers plate-hook, in combination, a body having a recess, a hook adapted to lie therein, said hook and body having inclined cooperating faces whereby said hook may be drawn downward by being forced internally within said recess, and means for so forcing said hook, substantially as described.

8. The combination of a box built up of brass plates on the point system, and a movable hook consisting of a plate having an overhanging edge adapted to occupy a vertical recess within said box and snugly engage the inner side of the extreme brass plates, substantially as described.

9. A printers plate-hook comprising a long narrow body adapted to be locked in a printers form with the length of said body parallel withthe plate and a hook adapted to be slid longitudinally within said body, the longitudinal movement of said hook operating to draw said hook downward and thereby lock the plate in the form, substantially as described.

10. In a printers plate-hook, in combination, a narrow body portion adapted to be locked in a printers form and a movable hook occupying said body portion and extending parallel with the length thereof, said hook having overhanging edges extended in opposite direction, substantially as described.

In testimony whereof we hereunto affix our signatures in the presence of two witnesses.
