Description

G. J. JBVERT.
WINDOW LOCK.
APPLICATION FILED MAY 5, 1011.
Patented Mar. 12; 1912.
UNITED STATES PATENT OFFICE.
CARL J'. JEVERT, OF CHICAGO, ILLINOIS.
WINDOW-LOCK.
To all whom it may concern:
Be it known that I, CARL J. Jnvnnr, a citizen of the United States, and a resident of the city of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Window-Locks, of which the following is a specification.
My invention relates to improvements in window locks and has for its object the provision of a window lock of improved construction and efficient in operation.
Other objects will appear hereinafter.
The invention consists in the combination and arrangement of parts hereinafter described and claimed.
My invention will be more readily understood by reference to the accompanying drawings forming a part of this specifica tion, and in which,
Figure 1 is an interior elevation of a portion of the meeting rails of window sashes equipped with a window lock embodying my invention, Fig. 2, a top plan view of the same, Fig. 3, a section taken on line m-w of Fig. 2, Fig. 1, a detail elevation of one of the spring links employed in the device, Fig. 5, a top plan view of one of the brackets employed in the device, and Fig. 6, a front elevation of the bracket shown in Fig. 5.
The preferred form of construction as illustrated in the drawings comprises two spring links 1 and 2 pivoted together at one end 3 and spread apart at the other end as shown. Link 2 is permanently pivoted to a bracket 4 secured to the lower rail 5 of the upper sash of the window. The freeend of link 1 is provided with a key hole slot 6 adapted to pass over a similarly shaped lug 7 on a pivoted stud 8 carried by a bracket 9 secured to the meeting rail 10 of the lower sash of the window.
In use with links 1 and 2 secured to the meeting rails 5 and 10, the upper sash may be lowered as indicated in dotted lines in Fig. 1, a distance equal to the sum of the lengths of links 1 and 2, or the lower sash may be raised an equal distance, or each sash Specification of Letters Patent.
Application filed May 5, 1911.
Patented Mar. 12, 1912.
Serial No. 625,303.
may be lowered or raised a component part of this distance. The sum of the lengths of links 1 and 2 is made so as to permit ample ventilation but at the same time prevent the entry of unauthorized persons. \Vhen it is desired to unlock the window so as to permit complete opening of the sashes, link 1 is rotated to proper position to bring key hole slot 6 in registration with lug 7, as indicated in dotted lines in Fig. 4, whereupon link 1 may be sprung over said lug and the sashes thus unlocked.
While I have illustrated and described the preferred form of construction for carrying my invention into effect, this is capable of variation and modification without departing from the spirit of the invention. I therefore do not wish to be limited to the precise details of construction set forth, but desire to avail myself of such variations and modifications as come within the scope of the appended claim.
Having described my invention what I claim as new and desire to secure by Letters Patent is:
The combination with the upper and lower sashes of a window, of two spring links pivotally connected together at one of their ends and the other end of one of said links being permanently pivoted to the meeting rail of the upper sash and the other end of the other link being provided with a key hole slot; and a stud secured to the meeting rail of the lower sash and provided with a locking lug adapted to pass through said slot when in one position and detachably pivot its link on said stud, said links being spread apart at the ends pivoted to said meeting rails and formed of spring metal, substantially as described.
In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
CARL J. JEVERT.
