SASH-LOGK.

Application filed December 27, 1909.

Specification of Letters Patent.

Patented Dec. 27, 1910.

Serial No. 535,107.

To all whom it may concern:

Be it known that 1, WILLIAM A. JORDAN, citizen of the United States, residing at New Orleans, in the parish of Orleans and State of Louisiana, have invented a new and useful Sash-Lock, of which the following is a specification.

This invention relates to an improvement in gravity locks, and although the same is especially adapted for use in connection with window sashes, it can be employed with equal success with window shutters and in analogous relations.

The principal object of the invention is to provide a catch which will operate automatically, upon the closing of the sash, to lock the same, and which will be readily unlocked upon raising the said sash.

Another object of the invention is to provide a device of the class described which is devoid of any springs and is therefore simple in construction, is easy of application, positive in operation, cheap to manufacture, and is not liable to get out of order.

WVith 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 claims hereto appended; it being understood that various changes in the form, proportion, sizev and minor details of construction, within the scope of the claims, may be resorted to without departing from the spirit or sacrificing any of the advantages of the inven tion.

In the drawing :-F igure 1 is a front elevation of a portion of a window showing the invention applied thereto. Fig. 2 is a detail longitudinal sectional view through the lower portion of the window and the lock, and Fig. 3 is a detail transverse sectional view of the same, taken on the line 33 of Fig. 1, in the direction of the arrows.

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

Referring to the drawing, 4 designates a window-frame of any suitable construction having an ordinary sill 5. Vertically slidable within the frame is a lower sash 6 which includes a bottom rail 7 of common form.

Centrally formed in the bottom rail 7 and communicating with the inner side thereof the pocket 8 and opens at its lower end at the bottom of the said rail;

Arranged to fit snugly within the pocket 8 is a casing which is designated as a whole by the numeral 10. The casing comprises an inner or vertical wall 11, a front flange 12 which engages and overlaps the front face of the bottom rail '7, and a connecting peripheral wall 13 which integrally con-- nects the said inner wall and the flange. The inner wall 11 is provided with a plurality of openings. 1 l14:. The flange 12 is provided at one end with an car 15 having an opening 16 formed therein, and the connecting wall 13 is provided at a point preferably opposite the ear 15, with an opening 17 If the window sash is narrow in cross-section as illustrated in Fig. 3 of the drawing, the casing is retained by screws 1818 which respectively pass through the said openings 16 and 17, and into the bottom rail 7. Should, however, the casing be of sufiicient thickness in cross-section, the screws 1818 may be passed through the openings 14L14t of the inner wall 10, and into the bottom rail 7. Thus it will be seen that two sets of openings are provided, either of which can be used, depending on the thickness of the bottom rail.

Depending centrally from the top of the casing and from the said flange 12 thereof, is an ear 19 having an opening 20 formed therein. Directly in rear of and conse quently in alinement with the said opening 20 is a corresponding opening 21 which is formed in the inner wall 11. The casing furthermore includes an opening 22 which is formed in the connecting wall 13 directly below the opening 20 and to one side thereof. This opening communicates with the interior of the casing and the recess 9 of the, sill bar.

A latch is employed which includes a substantially U-shaped arm 23 which is provided at the upper end with oppositely-extending transverse bearing pins 2&2t which respectively engage within the openings 20 and 21 of the inner wall 11 and the car 19. This arm is preferably formed of fiat metal of a width somewhat lessthan the depth of the casing 10, and is somewhat less in size than the interior of the casing. Thus it will be observed, by an inspection of Fig. 2 of the drawing, that the said arm 23 is normally spaced from the curved end of the said casing. The arm terminates at the lower end in a downwardly-extending integral arm 25 which is normally arranged directly below the pivots 24. This arm passes through the opening 22 in the connecting wall 13, and terminates in an enlarged head or catch 26. Y

Arranged on the sill 5 is a plate 27 which is secured thereto by screws 28 or other suitable fastening means. Upstanding from the plate, is a hook or keeper 29 of ordinary construction. This hook is arranged on the sill in such a position as to project into the recess 9 of the bottom rail 7 when the sash is down. The hook is also positioned at one side of the opening 22, and extends toward the catch 26, so as to be engaged by the same when the sash is closed, as shown by Fig. 2 of the drawing.

In operation, when it is desired to raise the sash, the fingers of the operator are inserted into the casing so as to lie within the U-shaped arm 23. The upward pull or lift by the operator will cause the U-shaped arm 23 to swing upon its pivots 2424 to the position shown by the dotted lines (Fig. 2), this movementcausing the catch to be disengaged from the hook 29.

When the arm has been released, it will by gravity, assume its normal position, so that when the sash is shut down, the catch will automatically engage the hook and thereby lock the sash against any upward movement.

The peculiar shape of the arm 23 is the essential feature of this invention. It lends itself readily to the particular service required.

What I claim is 1. A sash lock comprising a substantially elliptical-shaped casing adapted to be carried by a sash, said casing comprising an inner wall, a connecting peripheral wall, and a front flange, said peripheral wall having an opening at the bottom, a catch adapted from the bottom of said peripheral wall, the

lower end of the arm projecting through the opening of the said peripheral wall and terminating in a hook which is adapted, when the sash is closed, to automatically engage the catch and thereby lock the said sash, said arm swinging in a plane parallel to the plane of the sash.

2. In a sash-lock, the combination with a sash having a pocket formed in the bottom rail thereof, and a recess formed in thelower portion. of the rail and communicating with the said pocket and the bottom of the rail, a casing arranged within the pocket, said casing comprising an inner wall, a connecting peripheral wall, and a front flange, the flange having a central depending ear having an opening, and the inner wall having an opening in register therewith, the wall of the casing at the bottom having an opening communicating with the said recess, a catch secured to the sill and adapted to project into the said recess, and a substantially U- shaped arm arranged within and at one side of the casing and provided at one end with oppositely-projecting pivots which respectively engage in the said registering openings, the other end of the arm being pro vided with a depending arm which projects through the opening in the peripheral wall and into the said recess, and terminating in a hook which is adapted, when the sash is closed, to automatically engage the catch and thereby lock the said sash.

In testimony, that I claim the foregoing as my own, I have hereto aflixed my signa v ture in the presence of two witnesses.

WILLIAM ALEXANDER JORDAN.
