WINDOW-LOCK.
Specification of Letters Patent.
Patented Apr. 14, 1914.
Application filed May 23, 1913. Serial No. 769,393.
To all whom it may concern Be it known that I, JOHN C. CROWLEY, a citizen of the United States, and a resident of Toledo, in the county of Lucas and State of Ohio, have invented a certain new and useful Window-Lock; and I do hereby declare the following to be a full, clear, and exact .description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the characters of reference marked thereon, which form a part of this specification.
This invention relates to window locks, and has for its object the provision of a simple and improved lock of this character, which is strong and durable in its construc tion, inexpensive of manufacture, and easy to apply to the upper and lower sashes of a window, and which is adapted to securely lock the sashes against relative opening movements.
A further object of the invention is to provide a window lock which cannot be jimmied or unlocked by the insertion of tools between the sashes without the window,
thus making it burglar proof.
The invention is fully described in the following specification, and while, in its broader aspect, it is capable of embodiment in numerous forms, a preferred embodiment thereof is illustrated in the accompanying drawings, in which,
Figure 1 is a perspective view of my invention applied to the sashes of a window. Fig. 2 is a top plan view of the lock. Fig. 3 is a front elevation thereof with parts broken away, and Fig. 4: is a central longitudinal section thereof.
Referring to the drawings, 1 and 2 designate the upper and lower sashes, respectively, of a window, and 3 and 4 the two members of the lock, the former of which is carried at the inner side of the upper sash adjacent to its bottom edge and the latter at the upper edge of the lower sash. The lock member 3 is screwed or otherwise suitably secured in vertical or upright position to the inner side of the upper sash 3 adjacent'to one side edge thereof and has its opposite side edges turned over, as at 5, to cooperate with the body portion of the member to provide an elongated vertically disposed guide or slide-way for the lock member 4. The member 3 is preferably stamped from sheet metal for cheapness and rapidity of manufacture, and is provided at predetermined distances longitudinally thereof with openings 6 for the bolt or dog of the member 4 to engage into, as hereinafter more fully described. The member 4- of the lock is of hollow construction with its inner side, or at least a portion thereof, open to the base of the member 3 and with its side edges flanged outwardly, as shown at 7, to adapt them to engage under the rolled over side edges 5 of the member 3, whereby the two members are retained in tongue and groove engagement. The memher 4 is provided at its lower end with a foot flange or enlargement 8, which is adapted to rest upon the top edge of the lower sash and has openings for the insertion of retaining screws.
A dog 9 is mounted in inclined position within the hollow of the member 4 longitudinally thereof, and is shown, in the present instance, as having its tail or inner end, which is the end adjacent to the base of the member, provided with a longitudinally extending spur 10, which projects into a registering opening 11 in the member base whereby to cooperate with the wall of such opening to provide an end fulcrum for the dog. A coiled compression spring 12 is mounted within the member 4E and bears outwardly against the free end of the dog 9 to influence a projection of such end through the open side of the member 4: and into engagement with a registering opening 6 in the guide member 3, when moved into register therewith. A pin 13, in the present instance, is disposed within the open side of the member 4 to limit the outward movement of the dog or to coiiperate with the member 4 to retain the dog 9 and spring 12 in assembled position therein when removed from a window. The outer side of the dog 9 or that which is opposed to the member 3 is provided with a wing or flange 1A, which projects outwardly through a registering opening 15 in the outer or front side of the member 4 and provides a finger-grip to facilitate a withdrawal of the nose end of the dog 9 from engagement with an opening 6, as is apparent.
The guide member 3 is preferably shorter than the length of relative opening move ments of the window sashes, and to facilitate an entrance of the slide member 4 into e11- gagement therewith when the two members have been separated by an opening of the sashes, the upper or mouth end of the guide member is flared outwardly, as indicated at 16, and the lower ends of the flanges 7 of the slide member are beveled, as at 17.
It is found in practice that this form of lock is simple and inexpensive to manufacture and can be easily applied to the window sashes, and that when applied and the two parts are in locking position it is practically impossible to release the same from the outer side of the window by the insertion of a bolt or other unlocking agent between the sashes, as is customary in the opening of window locks by unauthorized persons.
I wish it understood that my invention is not limited to any specific construction or with internal guideways which flare outwardly at their upper ends, a slide member rising from the upper edge of the lower sash and having parts slidingly fitting into the guide parts of said member, said slide member having its inner side provided with a cavity with an opening in one end of the cavity, a dog disposed upright within the cavity of the slide member and having a the cavity for influencing an outward move-i ment of the free end of the dog.
In testimony whereof, I have hereunto signed my name to this specification in the presence of two subscribing witnesses. i
