lKEE'IPER FOR LOOK-BOLTS.

form its function, in co erating with the' lock, of holdin a door in c osed position and sufficiently tig t relative to its casing, to

prevent movement or`ra'ttling therein, must occupy at all times aproper osition relative to the catch-bolt, or lockingolt, or both.

It is the practice to set the plate in the door-j amb after the lock has been secured on the door, and owing. to the difficulty in properly positioning; the plate relative toits cooperating lock, the plate is often set inaccurately, necessitating its readjustment. Furthermore, sagging, shrinking and swelling of the door or casing changes the relative positions of -the keeper and lock-bolts, with the result of requiring the keeper to be reset.

Heretofore, the strike-plate has more usually been formed in one piece and is adapted to be secured by screws to the door-j amb, or the edge of one of double doors. It has therefore been necessary in readjusting a plate to cause it to occupy the desired position relative to the lock, to remove the attaching screws, change the position of the plate and then fasten it in its adjusted position by the screws, which again penetrate the material of the door or jamb, but in new places. As the required adjustments of the plate do not extend over an area of mor` than a small fraction of an inch, such fine readjusting of a plate is impossible after its fastening screws '.have `been repeatedly driven in ditferentplaces, as new screw-holes must be made each time a plate is reset, and the material of the door-jamb oi' door-edge is soon cut away to such an extent as to prevent the screws from holding in the wood at thfroper places.

y object is to overcome the, objections referred to by providing a construction of strike-plate or kee er which may be readily vand accurately a justed re eatedly on a door-jamb or door-edge wit out requiring the removal from such j amb or door-edge of the plate-attaching screws, therefore permitting adjustment of the plate without causin mutilation of or injury to its support; an my object is, further, to provide a construc- Speccation of Letters Patent.

My improved device comprises a rear or inner member 20 adapted to be permanently secured to a door-jamb or door-edge, as hereinafter described, and a front member 21 adjustably supported on the member 20. The member 20, which I preferably form of flexible sheet-metal, such as sheet-brass, is

` member upon itself, tovaffor outer and in` ner Walls 26 and 27, the central portion 22 being struck u sufficiently to cause its upper surface to e in approximately the same plane as that of the un er surface of the walls 26. Extending through the walls 26 and 27,

' near each end of the member 20, are screwholes 28, 29, at which the member is adapted to be secured, as by screws 3.0, in a recess 31 provided in a door j amb 32.

The adjustable member 21 has a struck-up central section 33 which is provided with the usual cam-extension 34 and catch-bolt and lock-bolt-receiving openings 35 and 36, respectively. These openings, which are relatively narrower than the openings 23 and 24 in the member 20, register with them, respectively, when the parts of the device are assembled as hereinafter ex lained. vThe ends of the member 21 are slig tly narrower than the ends of the member 20 and are provided with transversely elongated slots 37 and 37 which register with the adjacent screw-openings in the walls' 26 and 27, and through which the attaching screws 30 pass, when the member 21 is positioned on the member 20.

The arts are assembled before the device is applied to a door-jamb, or the like; and to accom lish this the members 2() and 21 are lateral y telescoped by inserting the ends of the member 21 edgewise into the adjacent recesses 25 and th-us between the walls 26 and 27 of the member 20, and drawing the -members together to the position re resented 1n Fig. 1, in which the member 21 ies fiatwise against the member 2() with its openings 35 and 36 registering with the o enings 23 and 24, respectively. The mem er 20, thus carrying the member 21, is then secured in the desired position in the doorjamb or other recess, by the screws 30, which serve, when screwed in tightly, to irmly clamp the member 21 to the member 20, and

to render the clamping hold positive, I prefer to roughen the surfaces of the end-portions of the member 21, as represented at m, and the inner surfaces of the walls 26 and 27 as represented at ly. When, for any reason, readjustment of the member 21 is desired, the screws 30. may be slightly withdrawn, thereb removing the pressure oi' the walls 26 an 27 against the endortions of the member 21 and allowing t e latter to be moved to the desired position on the member 20, in which adjusted osition it may then be clamped' by again tig tening the attaching screws.

In the construction illustrated in Figs. 8 to 13 inclusive, the member 20 is adapted to be secured to a door-j amb or door-edgethrough the holes 28 the intermediate screw-holes 29 being provided to receive machine-screws or set-screws 38 which pass through the openin s 37 and screw into nuts'39, on the rear' si e of the member 20. I prefer to form the nuts 39 in one piece 40, as shown in Figs. 9, 11 a d 12, and to provide a notch 41 at one side for receiving the end of a tongue 42 stamped' out of the member 2() and bent backward vto press against the piece 40 and rigidly hold its nut-portions in place on the back of the member. the member 20 is provided on its rear face with a transversely sliding nut 43, which moves in dovetailed guides 44 on the member 20. The member 21, shown in Flg. 10, has a screw-hole 45 between its openings 35 and 36, and the member 20, as shown in Fig. 8, is provided with a transversel -elongated opening 46 registering with the ole 45. A

which are tightened after the adjustment has been effected.

In Figs. 14 to 19, inclusive, I have `illustrated a construction embodying my invention, which under certain conditions is preferred to either of those hereinbefore described. This construction is the same as that shown in Figs. 1 to 7 inclusive, excepting as to the following particulars. The 1nner member of this construction instead of having its central section 22 struck up, has this section in the same plane as' its ends, with its catch-bolt and door-boltreceiving openings 23 and 24 relatively longer and wider then the corresponding openings 35 and 36in the outer member 21, Its outer member 21 is shorter than the inner member 20 and its slots 37 and 37 a are rovided of a size considerably lar er than t e attaching screws 30 whereby t e member 21 may be adjusted up and down or sidewise on the member 20 -and held in adjusted position thereon by the attaching screws to permit the catch-bolt and lock-bolt-receiving openings to be properly positioned relative to the coperating bolts, should readjustment of the keeper be required by the sagging, shrinking or swelling of the door.
