BENTON E. WRIGHT, OF LODI, CALIFORNIA. I

ADJUSTABLE STRIKING-PLATE.

Application filed August 26, 1918. Serial No. 251,396.

To all whom it may concern Be it known that I, FEN'roN E. WRIGHT, a citizen of the United States of America, residing at Lodi, in the county of San Joaquin, State of California, have invented certain new and useful Improvements in Adjustable Striking-Plates; and I do declare the following to be a clear, full, and exact description of the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this application.

This invention relates to improvements in striking plates as commonly used in connection with door catches and locks, the principal object of the invention being to produce an adj ustab'le plate for the purpose, in which the orifice for the catch or look is adjustable both in a horizontal and a vertical direction.

It very often happens that the carpenter was not quite accurate in his fitting of the striking plate, or the door afterward sags on its hinges. In this latter case, which is a common source of annoyance, the catch or look either does not fit in the orifice in the striking plate or is made to do so only by the exertion of considerable upward pressure on the door. This may be easily remedied with my improved plate by lowering the adjusta'ble member.

Another case is side-fit, when any wind or vibration causes the catch to rattle in the plate. This is taken care of by horizontal adjustment of the striking plate.

A further object is to provide a simple and inexpensive device, and yet one which will be exceedingly effective for the purposes for which it is designed.

These objects, I accomplish by means of such structure and relative arrangement of the parts as will fully appear by a perusal of the following specification and claims.

On the drawings, similar characters of reference indicate corresponding parts in the several views:

Figure 1 is a front elevation ofmy im proved striking plate as secured to a door casing.

Fig. 2 is a rear elevation thereof, detached.

Fig. 3 is a longitudinal section through the center of the plate.

Referring now more particularly to the characters of reference on. the drawings, the numeral 1 designates the back or permanent member of the plate. This plate is provided that of an overly loose with a longitudinal orifice 2 of suitable height and width and with holes 3 near the top and bottom for the reception of wood screws, whereby the plate is secured to the casing 4. Situated between the holes 3 and orifice 2 are vertical slots 5, on both sides of which are upstanding lugs or flanges 6. Resting against the outer face of the member 1 is the adjustable member 7, which is of the usual size and shape and provided with two rectangular orifices 8 and 9 positioned to receive the catch and lock, respectively, of a standard door lock. Above and below said orifices are horizontal slots 10, the center line distance of these slots being the same as the distance between centers of the slots 5 in the member 1. These slots 10 are countersunk on both sides, as shown at 11, in order that the position of the member 7 may be suited to the position of the door. Flat head bolts 12 pass through slots 10 and 5 and are provided :with nuts 13 which impinge against the back side of the member 1 and are kept from turning by the ridges 6 thereon. The orifice 2 is wider and longer than the orifices 8'- and 9 in order to allow of vertical and horizontal adjustment of the member 7 without the edges of the orifice 2 projecting beyond the edges of the orifices 8 and 9.

This device may of course be used with any boxes, trunks, etc, which have a locking means similar to that used on doors.

From the foregoing description it will readily be seen that I have produced such a device as substantially fulfils the objects of the'invention as set forth herein.

While this specification sets forth in detail the present and preferred construction of the device, still in practice, such deviations from such detail may be resorted to as do not form a departure from the spirit of the.

invention, as defined by the appended claims.

Having thus described my invention, what I claim as new and useful and desire to seand below said orifices substantially in alinement with the first named slots whereby the two plates may be bolted together, the last named plate being capable of horizontal and vertical adjustment with regard to the first named plate.

2. A striking plate for door locks comprising a plate adapted to be rigidly secured to the door casing, said plate being provided with a longitudinal rectangular orifice therein and vertical slots above and below said orifice, parallel lugs on both sides of said slots on the under side of the plate, a second plate slid'able on the outer face of the first named plate provided with rectangular orifices to receive the door catch and look therethrough and with horizontal slots substantially in alinement with said vertical slots, bolts passing through each pair of slots, and

nuts on the bolts, the sides of the nuts seating between the lugs on the plate whereby the bolts may be retracted on the nuts from the outside to loosen the outer plate and adjacent the vertical or horizontal position thereof.

In testimony whereof I aifix my signature in presence of two witnesses.
