\VILLIAM H. LOOMIS, OF ST. PETER, MINNESOTA.
SLIDING-DOOR LOCK.
SPECIFICATION forming part of Letters Patent No. 623,552, dated April 25, 1899.
Application filed February 4,1898. Serial No. 669,066. (No model.) i
. doors and to provide a simple, inexpensive,
and eflicient one capable when two sliding doors come together of automatically locking the same and adapted to be operated from either side of either door to unfasten the doors.
The invention consists in the construction and novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended.
In the drawings, Figure 1 is a sectional View of the left half'of the lock. Fig. 2 is a similar View of the lower portion of the right half of the lock, showing how the catches of the two halves engage each other. Fig. 3 is. a detail sectional view of the transverse key. Fig. 4 is a detail perspective View illustrating the construction of the bolt and the push-rod and showing the connection between the same. Fig. 5 is a detail view of a portion of a sliding door, illustrating the arrangement of the lock and the escutcheon-plate.
Like numerals of reference designate correspondin parts in all the figures of the drawings.
1 designates the casing of the left-hand half of the lock, designed to be mounted in a mortise of a sliding door 2, as illustrated in Fig. 5 of the accompanying drawings, and the said casing is designed to be provided at one side with a removable face-plate of the ordinary construction. A sliding pull 3 is arranged in the upper portion of the casing and is adapted to project through an opening of the same sufliciently to be grasped in closing the door, and its sliding movement is limited by a stud 4t, mounted on the casing and arranged in a longitudinal slot 5 of the pull. The slot 5 is horizontal and the stud assists in supporting the pull in proper position. The sliding pull is retained within the casing of the lock bya catch 6, pivoted between its ends at '7 and provided at its outer end with a tooth 8 for engaging a shoulder 9 of the pull, and said catch is retained in such engagement by a spring 10. The spring 10 is composed of two sections or leaves 11 and 12 and is mounted at the top of the casing, near the inner end thereof, being preferably arranged in the corner, as clearly shown in Fig. 1 of the accompanying drawings. The arm or side 11 of the spring engages the inner or rear end of the catch 6 at theupper edge thereof, and the other arm or side is substantially U-shaped and bears against the inner end of the sliding pull, whereby when the catch is disengaged from the shoulder 9 the pull will be automatically thrown outward. The outer end of the catch is beveled and is engaged by an inner beveled end 13 of a push-bar 14, located beneath the pull and having its outer end 15 reduced and projecting through an opening of the outer end of the casing. Vhen the pushbar, which has its inner end bent upward slightly, is moved inward, it depresses the beveled front end of the catch and carries the same out of engagement with the sliding pull, which is thrown outward by the spring as soon as it is released. The sliding pull may be returned within the casingby hand; but if it is not it will be automatically returned when the sliding bars come together.
In the lower portion of the casing is mounted a reciprocating bolt 16, disposed horizontally and provided at its outer end with a catch and connected at its inner end by a le ver 17 with a push pin or rod 18. The catch at the outer end of the bolt 16 is adapted to project through an opening of the casing and interlock with the reversely-arrangcd catch of a bolt 16 of the right-hand half of the look, as clearly illustrated in Fig. 2 of the accon1- panying drawings. The lever 17, which is fulcrumed between its ends at 19, is pivoted at its terminals to the inner ends of the bolt and the push-pin, whereby when the latteris vided with a collar 21, forming a stop for the spring and arranged to abut against the inner face of the outer end wall of the casing to limit the outward movement of the pin.
One side each of the bolts 16 and 16 is oppositely beveled at 22 and is engaged by a transverse key 28, and the opposite side of the bolt is engaged by a spring 24, which is substantially U-shaped. The bolt is supported between the key and the spring, and the former is provided with a central V-shaped recess 25, having oppositely-inclined faces adapted to engage the inclined faces of the bolt, whereby when the transverse key is pressed inward the bolt will be moved against the action of the spring 24 and disengage it from the other bolt. In the left-hand half of the lock the spring is located beneath the bolt and the key is arranged above the same, and in the righthand half of the lock the spring and the key are reversely arranged.
In order to enable the parts to be readily assembled, the transverse key is composed of two sections connected at their inner ends by a pin 26, mounted on one of the sections and engaging a socket of the other section, as clearly shown in Fig. 3 of the accompanying drawings. The outer ends 27 of the sections are reduced and threaded and receive caps 28, which are capable of adjustment to enable the ends of the key to be adjusted to suit the thickness of the door to which the lock is applied. The ends of the transverse key are preferably arranged in openings of escutchcon-plates 29, as illustrated in Fig. 5 of the accompanying drawings, and it is adapted to be operated from either side of either door.
The invention has the following advantages: The lock, whichis simple and com paratively inexpensive in construction, is automatic in its operation and is capable of locking two sliding doors when the latter come together. -Itis also adapted to be operated from either side of either door to disengage the catches for releasing the doors, and the sliding pull, which is normally held within the casing, is adapted to be readily extended, and the same may be returned by hand or automatically returned by the closing of the doors.
Changes in the form, proportion, and minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of this invention.
What I claim is- 1. In a device of the class described, the combination of a reciprocating bolt having an oppositely-beveled portion, and a transverse key having a recess to engage the beveled portion and provided with threaded ends, said key having interiorly threaded caps mounted on the threaded ends and adapted to vary the length of the key, substantially as described.
2. In a device of the class described, the combination of a reciprocating bolt having a catch, and a transverse key en gaging the bolt and composed of two sections connected at their inner ends, each of said sections having its outer end capable of longitudinal adjust ment, substantially as described.
3. In a device of the class described, the combination of a reciprocating bolt having a catch and provided at one side with an oppositely-beveled edge, a spring engaging the opposite side of the bolt, a transverse key having a recess receiving the beveled portion of the bolt and adapted to depress the latter, a lever fulcru med between its ends and pivoted at one end to the bolt, and a push-pin connected with the other end of the lever, substantially as described. I
4. In a device of the class described,'the combination of a casing, a reciprocating bolt having a catch, a spring-actuated push-pin, and a lever pivoted between its ends and connected with the bolt and push-pin, substantially as described.
