SASH-LOCK.

Specification of Letters Patent.

Patented July 21, 1914.

Application filed January 10, 1913. Serial No. 741,304.

To all whom it may concern:

Be it known that I, HENRY J. STANG, a citizen of the United States, residing at Bison, in the county of Bush and State of Kansas, have invented certain new and useful Improvements in Sash-Locks, of which the following is a specification, reference being had to the accompanying drawings.

This invention relates to new and useful improvements in locks and more particularly to sash locks, the object of the invention being to provide a sash lock wherein the locking bolt is normally retained in a locked position and also to provide means whereby the bolt can be quickly and easily thrown to an unlocked position.

Another object of the invention is to provide a casing of novel construction in which the various parts of the locking mechanism are inclosed.

A further object of the invention is to provide a lock of the above character which will possess advantages in points of efliciency and durability, is inexpensive of manufacture and at the same time is simple in con struction and operation.

With the above and other objects in view, the invention consists in the novel features of construction and the combination and arrangement of parts to be hereinafter more fully described, pointed out in the claim and shown in the accompanying drawings, in which Figure 1 is a view in top plan of a lock constructed in accordance with my invention. Fig. 2 is a top plan View, the cover being removed. Fig. 3 is a front view of the keeper member and Fig. 4 is a side elevation of the look.

In the construction of my improved look, I provide a casing 1 which is preferably rectangular in shape and having one side open as shown at 2. The open side 2 is closed by means of a suitable cover 3 having a centrally arranged tongue 4 formed at one side thereof and adapted to be bent rearwardly and engage over the side of the casing 1 to securely hold one side of the cover in position. The other side of the cover is provided with the spaced tongues 55 which are adapted to be bent downwardly over the side of the casing to securely retain this side of the cover in position. Thus it will be apparent that by means of the tongues 4 and 5 the cover is securely held in place and the same may be readily removed by bendmg outwardly upon the tongue, it being understood that the cover is made of suitable metal whereby the tongues will be supplied with sufiicient resiliency to allow of the.

bendingof the same. 1 I

Arranged transversely within the casing for sliding movement is the locking bolt 6 one end of which is adapted to project through an opening 7 formed in one of the side walls of the casing and engaged beneath the keeper member 8. The material which is cut from the opening 7 is divided in the center and each half bent inwardly into the casing to form spaced flanges 7 adapted to be disposed upon opposite sides of the bolt 6 and brace the same against lateral movement. The bolt 6 is nor-' mally retained in a locked position by means of the leaf spring 9 which is bent upon itself and having its ends arranged in resilient spaced relation so that one end thereof engages the inner end of the bolt and the other end engages the rear side wall of the casing to resiliently hold the locking bolt in its normal position.

Mounted for rotary movement within the casing is a drum 10, one end of which projects outwardly through the casing to form a suitable fingerhold 11 whereby the drum may be readily turned. Pivotally secured at one end to the locking bolt adjacent the inner end thereof is a rod 12, the other end,

of said rod being slidably directed through the drum 10 so that when the drum is rotated by means of the finger hold 11, the bolt will be withdrawn from its locked position as shown in Fig. 4, placing the spring 9 under tension. Thus as the drum is released, the tension of the spring 9 will return'the locking bolt to its locked position.

The locking bolt 6 is provided with an elongated slot 13 in which is disposed a pin 14, said pin being carried by the casing and adapted to limit the outward sliding movement of the bolt when thrown to its locked position. 7

From the above description taken in connection with the accompanying drawings, it will be readily apparent'that I have provided a simple and durable sash lock whereby the operating mechanism thereof is'disposed within a casing of novel construction and it will also be apparent that I have provided a lock which is composed of comparatively few parts, is simple in construction and operation and can be manufactured at comparatively low cost.

/Vhile I have shown and described the preferred form of my invention, it will be obvious that various changes in the details of construction and in the proportions may be resorted to for successfully carrying my invention into practice without sacrificing any of the novel features or departing from the scope of the appended claim.

What I claim is A sash lock including a casing provided with an opening, a bolt slidably supported within the casing and adapted to be directed through the opening thereof, a rod having one end pivotally connected to the bolt, a drum rotatably mounted within the casing and through which the free extremity of the rod is slidably directed, said drum being provided with means whereby it may be rotated.

In testimony whereof I hereunto afliX my signature in the presence of two witnesses.

HENRY J. STANG.
