Section 9 is formed with a series of longitudinal fail to register with the opening I8 in the strike plate due to sagging of the door or other conditions, it is merely necessary to grip the connecting web l9 with a pair of pliers and exert a slight outward pull thereon against the tension of the springs 26 until the teeth on the attaching plate and strike plate become disengaged when, by moving the strike plate l6 either vertically or laterally of the door jamb, the opening l3 in the strike plate may be properly alined with the sliding lock bolt of the door look, as will be readily understood. When the proper adjustment of the strike plate has been effected, the springs 2-1 will automatically return the strike plate iii to normal position and in which position the teeth will interengage and prevent further movement of said strike plate.

While it is preferred to make the attaching plate in two sections, it will, of course, be understood that said attaching plate may be of integral 20 construction, if desired. It will also be understood that the lcck strikes may be made in different sizes and shapes to accommodate any style or type of door without departing from the spirit of the invention.

Having thus described the invention, what is claimed as new is:

1. A look strike comprising an inner attaching plate, an outer strike plate having face to face engagement therewith, and yieldable means for 3 holding the strike plate in a set position and permitting shifting thereof to another set position in its initial plane.

2. A look strike comprising an inner attaching plate and an outer horizontally and longitudinally adjustable strike plate fitting against the outer face thereof, said plates having confronting faces provided with inter-engaging members, pins extending through said plates, and springs surrounding the pins for normally and yieldably 4 holding the strike plate in a set position.

3. A look strike comprising a body having a seating recess and provided with longitudinal and transverse teeth, a strike plate adjustably mounted within the seating recess and provided with teeth adapted to engage the teeth on the body, pins secured to the strike plate and loosely extending through the body plate, and coiled springs surrounding the pins for normally and yieldably holding the teeth on the strike plate and the body 50 in engagement with each other and maintaining the strike plate in an adjusted position.

4. A look strike comprising a body having a seating recess formed therein and provided with longitudinal and transverse teeth, there being 55 spaced openings formed in the body and extending through said teeth, a strike plate adjustably mounted within the seating recess and provided with teeth coacting with the teeth on the body,

pins secured to the strike plate and extending through the openings in the body and having heads at their free ends, washers fitted around the pins and spanning the openings in the body, and coiled springs fitted around the pins and bearing against the heads of said pins and the adjacent washers to maintain the strike plate in an adjusted position.

5. A look strike comprising a body having a laterally extending tongue and provided witha seating recess and a bolt receiving opening in the recess, the inner wall of the recess being formed with longitudinal and transverse teeth about the bolt receiving opening, there being spaced fastener receiving openings formed in the body above and below the bolt receiving opening and intersecting the adjacent teeth, a strike plate adjustably mounted in the seating recess and provided with corresponding teeth for engagement with the teeth on the body, pins threaded in the strike plate and extending loosely through the openings in the body and formed with heads at their free ends, washers fitted over the pins and bearing against the rear face of the body about the fastener receiving openings therein, and a coiled spring interposed between each washer and the head of the adjacent pin.

6. A lock strike comprising a body having a seating recess therein and provided with a bolt receiving opening and teeth about the opening, a strike plate adjustable longitudinally and laterally within the seating recess and provided with teeth inter-engaging the teeth of the body, pins rigidly secured to the strike plate and extending loosely through the attaching plate, and resilient means carried by the pins for normally and yieldably holding the strike plate in an adjusted position with the teeth on the strike plate and attaching plate in gripping engagement with each other.

7. A look strike comprising a body formed of rigidly united front and rear plates, the front plate being formed with an opening exposing a portion of the rear plate and together therewith providing a seating recess, the exposed portion of the rear plate having a roughened surface Visible through the opening of the front plate, an adjustable strike plate seated in said recess and provided with a roughened surface coacting with the roughened surface on the rear plate, guide pins secured to the strike plate and passing loosely through openings in the rear plate, and springs surrounding the pins and bearing against the rear face of the rear plate for normally and yieldably holding said roughened surfaces in gripping engagement with each other to maintain the strike plate in an adjusted position.
