LOCK FOR SLIDING DOORS.
Specification of Letters Patent.
Patented Jan. 5, 1909.
Application filed January 3, 1907, Serial No. 350,668. Renewed May 26, 1908. Serial No. 435,120.
T 0 all whom it may concern: 7
Be it known that we, AnoLF CARL KREUT- ZER and JAMEs C. Jones, citizens of the United 'States, residing at Philadelphia,
county of Philadelphia, and State of Pennsylvania, have invented a certain new and useful Improvement in Looks for Sliding Doors, of Which the following is a specification.
Our invention relates to a new and useful improvement in looks for sliding doors, and has for its object to provide an exceedingly simple and effective device of this description which when placed upon a sliding door Will securely lock the same, the keeper pass ing within the look so as to prevent access thereto, thereby preventing it from being unlocked except by the use of the proper key.
With these ends in view, this invention consists in the details of construction and combination of elements hereinafter set forth and then specifically designated by the claims.
In order that those skilled in the art to which this invention appertains may under-' stand how to make and use the same, we will describe its construction in detail, referring by letter to the accompanying drawing in which my improved lock is shown in perspective, the cover being removed so as to show the mechanism therein.
In carrying out our invention as here embodied, A represents the casing of the lock, in which is pivoted the latch B at C. The forward end of this latch has formed thereon a hooked nose D which is adapted to engage the hooked nose of the keeper E, while the heel end of this latch extends between the guard F and the case in order that it may be acted upon by the key G for unlocking the latch.
H represents a spring, so located as to force the heel end of the latch upward and its nose D downward for throwing said nose into engagement with the nose of the stationary keeper E when the latter passes within the casing.
I represents a slide located within the easing in which is journaled the roll J adapted to travel upon the under side of the latch, and this slide is normally forced forward by the spring K, during which movement the roll forces the nose end of the latch upward so as to carry it out of the path of the nose of the keeper E, the result being that when the keeper is withdrawn from the casing the latch is held in an elevated position until the keeper again passes within the casing, and in so doing forces the slide backward permitting the nose of the latch to enter into engagement with the nose of the keeper.
In practice, the lock may be secured to the sliding door and the keeper E to the jamb thereof or vice versa, and when the door is closed the keeper will pass into the casing forcing back the slide, thus permitting the latch to lock the keeper against withdrawal until the nose of the latch has been elevated by the proper manipulation of the key. This prevents the keeper from being disengaged from the lock in any manner except by the use of the key, since the parts which are engaged are entirely concealed within the casing.
If desired the forward end of the slide I may be arranged to close the opening in the casing through which the keeper is intended to pass, thus keeping moisture or dirt out of the casing.
Having thus fully described our invention, what we claim as new and useful, is-
1. A lock consisting of a casing, a latch pivoted therein, a spring for holding said latch in its locked position, a slide fitted to move below the latch, a roll carried by said slide for elevating the latch when the keeper is withdrawn and a spring for normally forcing said slide forward, as specified.
2. In combination, a casing, alatch pivoted therein, a nose formed upon one end of the latch, a spring for forcing the nose end of the latch downward, a slide adapted to travel beneath the latch, a roll carried by said slide for elevating the latch when the slide moves forward, a spring for forcing said slide for ward and a keeper adapted to pass within the casing and force the slide backward whereby the latch will be lowered into its locking position, as specified.
In testimony whereof, we have hereunto aflixed our signatures in the presence of two subscribing witnesses.
