E. F. BRITTINGHAM LOCK STRIKE Filed Feb. 24, 1928 Patented June 10, 1930 UNITED STATES PATENT OFFICE ELISHA F. BRITTINGHAM, 0): LOS ANGELES, CALIFORNIA, ASSIGNOR TO SARGENT & r 1
COMPANY, OF NEW HAVEN, CONNECTICUT LOCK STRIKE Application filed February 24, 1928. Serial No. 256,620.
This invention relates to a lock strike, and more particularly to an improved form of lock strike and improved manner of securing the same to the jamb of a door or the like.
The lock strike of this invention, while not limited to use with a spring latch or lock to be mounted on an outer surface of a door, is especially useful in connection with such a form of lock. According to the prior art, the usual lock strike used in connection with a lock of this type is provided with a bolt-receiving body which is mortised into an outer face of a door jamb or the like, and is provided with a laterally extending flange or other portion which is mortised into an inner face of the door casing. Such strikes are usually secured to the door casing by means of screws which pass from the exterior of the strike through openings in the body thereof and into the door casings. In order to provide room for passing the screw or screws through the body of the strike, the usual strike is provided with a much larger portion engaging the outer face of the door jamb than would otherwise be necessary and requiring, in most instances, that this portion be mortised into the j amb.
In order to provide a lock strike having a more sightly appearance than the usual strike, it is proposed in the present invention to provide a strike which may be mounted on the j amb of the door without the use of exposed fastening means.
Another object of the invention is to provide a form of lock strike which may be mounted on the jamb of a door or the like without the necessity of mortising the strike into the jamb or other support.
A further object of the invention is to provide a lock strike in which there is provided a concealed but eflicient means for securing the strike to the jamb of the door.
To these and other ends, the invention conslsts 1n the novel features and combination of parts to be hereinafter described and claimed.
In the drawings,
Fig. 1 is a fragmentary view of a door and a door casing showing a preferred embodiment of my invention mounted thereon; Fig. 2 is a view alongline 22 of Fig. 1;
Fig. 3 is a cross-sectionalview along line 3-3 of Fig.2; and
Fig. A isan end view of my improved lock strike, taken in a direction similar to Fig. 3.
Referring now to the drawings in which I have shown a preferred embodiment of my invention, the reference numeral 5 indicates in general a portion of a door having mounted thereon a lock casing 6, which may be of any usual or preferred type, and which will not therefore be described herein in detail, the lock casing 6 being secured to the door 5 by suitable means, as for example, screws 7, and being provided with a latch bolt 8, and the usual thumb turn 9 for retracting the bolt.
Adjacent the door dis a door jamb 10, having mounted thereon my improved form of lock strike 11, which is provided with a bolt retractingface l2, and a bolt receiving opening 13. trike 11 is provided with a relatively narrow face 14, which abuts against the outer face 15 of jamb 10, and a rearwardly extending flange 16, which may be secured to the inner face 17 of jamb 10 by suitable means, as, for example,screws 18. The side of strike 11 abutting against the face 15 of jamb 10 is preferably solid and passing from the interior of strike 11 through this solid portion and into jamb 10 is a suitable fastening meansherein shown inthe form of screw 19. As shown in the drawings, the face 14 is of less width than the depth of the bolt receiving opening 13 and the wall 20 of strike 11 extends outwardly from jamb 10 substantially at an acute angle.
In use, my improved form of lock strike may be placed in a suitable position on the jamb of a door opposite the lock with the face 14: abutting the outer face of the amb and the screw, or other fastening means,
19 passed through the opening in the strike body provided for that purposes and into the jamb. It will be seen from Figure 1 of the drawings that the screw 19 is entirely concealed when the door is closed. By eX- tending wall 20 in a direction substantially forming an acute angle with the face of the door .jamb, it is possible to mount the strike on the edge portion of the jamb where it Will not interfere with any beading, molding, or other ornamental portion of the j amb, while at the same time the face 14 forms a suitable support for the strike.
By providing the lock strike with a solid portion at the back of the bolt opening and. a
passing a fastening member through this portion into the face of the door jamb, I am enabled to omit the laterally extending flange usually provided at the face of the door jamb through which the fastening members are ordinarily passed. This flange must be mortised into the face of the door jamb and by omitting that element I provide a lock strike which may be secured in place much more easily, and at the same time will not deface the door j amb.
While I have shown a preferred embodiment of my invention, it is to be understood that the same is not to be, limited to all the jamb abutting face thereof and into the jamb of the door.
3. A look strike adapted to be applied to a door jamb comprising an inner face portion abutting against and secured to the door jamb and an outer wall substantially parallel to said inner face portion and of greater width than said face portion, and a rear wall inclined rearwardly and outwardly from the door jamb and connecting. said outer wall and face portion.
In witness whereof, I have hereunto set my hand this 2d day of February, 1928.
