EPHRAIM WIMER, OF ORABBOTTOM, VIRGINIA.

SASH-LOGK.

To all whom it may concern:

Be it known that I, EPHRAIM WIMER, a citizen of the United States, residing at Crabbottom, in the county of Highland and State of Virginia, have invented a new and useful Sash-Lock, of which the following is a specification.

The invention relates to improvements in sash looks.

The object of the present invention is to improve the construction of sash locks, and to provide a simple, inexpensive and efficient one of great strength and durability, adapted to be readily applied to a window and capable of securely looking a sash in its closed position and at various adjustments, and of effectually preventing the sash from being raised from the exterior.

With these and other objects in view, the invention consists in the construction and novel combination of parts hereinafter fully described, illustrated in the accompanying drawing, and pointed out in the claim hereto appended; it being understood that various changes in the form, proportion, size and minor details of construction, within the scope of the claim, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawing :Figure 1 is a perspective view of a sash lock, constructed in accordance with this invention and shown applied to a portion of a window. Fig. 2 is a horizontal sectional view of the same. Fig. 3 is a vertical sectional view of the sash lock.

Like numerals of reference designate corresponding parts in all the figures of the drawing.

The window sash 1 is equipped with a vertical keeper bar 2, adapted to be engaged by a horizontally swinging locking arm 3, hinged to a plate 4 by a pintle 5. The plate 4 is pierced by screws 6, or other suitable fastoning devices for securing the plate to the window frame 7, as clearly shown in Fig. 1 of the drawing. The said plate is provided at its inner edge with vertically alined eyes 8, and the locking arm has a similar eye 9 at its inner end. The eye 9 of the locking arm is arranged between the upper and lower eyes 8 of the plate, and is secured to the latter by means of the vertical pintle 5, which passes through the said eyes. The locking arm is Specification of Letters Patent.

Serial No. 421,038.

adapted to swing horizontally to engage it with and disengage it from the keeper bar 2.

The keeper bar 2, which is secured by screws 10, or other suitable fastening devices. to the sash at one side thereof, is designed in practice to be about twenty inches in length, more or less, and it is provided at intervals of two inches, or thereabout, with recesses 11. The recesses, which extend across the keeper bar, are adapted to receive the looking arm 3, and have horizontal lower walls. The upper walls of the recesses are provided with grooves 12, adapted to receive the upper edge of the locking arm, which after being swung into a recess, is engaged with the top groove by a slight downward movement of the sash. This will prevent the locking arm from being swung outward before being dis engaged from the upper wall of the sash. By this construction, there will be no liability of the sash lock being accidentally unfastened by small children. The locking arm extends beyond the keeper bar, when in engagement with the same, and is equipped at its free end with a knob 13, or other suitable means for enabling the locking bar to be readily oper ated.

Having thus fully described my invention, what I claim as new and desire to secure by Letters Patent, is

A sash lock comprising a keeper bar pro vided at intervals with horizontal recesses having grooves in their upper walls, a plate provided at its inner edge with vertically alined spaced eyes, a pintle arranged in the eyes, and a horizontally swinging locking arm provided at one end with an eye arranged between the said eyes and hinged to the plate by the said pintle, said locking arm being arranged to swing into and out of the recesses of the keeper bar and adapted to be engaged with the grooves at the tops of the recesses by a slight downward movement of .the sash, whereby the locking arm and the keeper bar are interlocked to hold the former against outward movement.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two witnesses.

EPHRAIM WIMER.
