WILLIAM J. WEST, OF CLAY CITY,.WAHINGTON.

SASH-LOCK.

Specification of Letters Patent. Patented Nov, 16, 1915.

Application filed June 15, 1915. Serial No. 34,156.

T allwkom it may concern:

Be it known that I, WILLIAM J. Wear, a citizen of the United States, residing at Clay City, in the county of Pierce and State of W'ashington, have invented certain new and useful Improvements in Sash-Locks, of which the following is a specification, reference being had to the accompanying drawings.

The present invention relates to new and,

useful improvements in sash locks for windows and, as its principal object, aims to provide an improved device of this character which is relatively simple in construction and may, therefore, be cheaply manu factured, and is of such design that it may be easily and quickly applied to or removed from any window casing of standard design without requiring any alterations or changes in the construction of either the casing or the sashes and without necessitating the application of permanent fastening devices to either the casing or sashes.

A further and more specific object of the invention is to provide a sash lock of the character above stated which consists generally in two hi-ngedly united sections, one of which constitutes the attaching plate and is accompanied by spurs adapted to be embedded in the sash bar or window casing for holding the device against movement, and the other of which is formed in the nature of a wedge-shaped locking block which is designed to be inserted between the two sashes for preventing movement of the two sashes relative to each other.

, The above and other incidental objects of a similar nature, which will be hereinafter more specifically treated, are accomplished by such means as are illustrated in the accompanying drawings, described in the following specification, and then more particularly pointed out in the claims which are appended hereto and form a part of this application.

With reference to the drawings, wherein there has been illustrated the preferred embodiment of the invention as it is reduced to practice and throughout the several views of which similar reference numerals designate corresponding parts, Figurel is a perspective view illustrating two possible applications of the sash lock to a window sash; and Fig. 2 is a detail perspective view of the sash lock.

The structural details of the preferred form of the sash lock are illustrated in deta l 1n Fig. 2 and, for this reason, reference will first be had to this figure. As there shown, the lock consists generally in an at tachlng or body plate and a wedge block 11. The two members 10 and 11 are hingedly united by means of a hinge 12 which may be formed either as an integral part of the plate and block or may be designed as a separate element and suitably secured thereto in any desired manner. The plate and block are both preferablyv formed as metallic castings although, may alone be made of metal and the block formed of wood or some light but tough composition.

if desired, the plate The attaching or body plate 10 is preferare relatively sharp and adapted to be em- I bedded in either the window casing or the window sashes, as will be hereinafter more particularly pointed out, for holding the locking device in the proper position and against movement. These studs or spurs are, of course, relatively short since it is not intended that the present device shall, when applied to the window casing or window sashes, deface these members.

The actual construction and arrangement of the several parts of the lock device being thus disclosed, reference will now be had to Fig. 1 and particularly to the right hand side thereof, wherein the device is shown as attached to the window casing. As disclosed, the attaching or body plate is applied to the vertical face board 14 of the window casing and is disposed in the vertical line which separates the upper and lower sashes.

venting the lower sash from being opened.

In some instances, it may be desirable to As previously stated, the body plate is held 1n proper position and against movement so apply the locking device that it will hold both the upper and lower sashes from movement. Such application of the device is illustrated at the left, in Fig. 1. As therein shown, the spurs of the plate 10 are forced into the vertical bar 18 of the'upper sash and the lower end of the wedge block inserted between the meeting rails 16 and 17 of the upper and lower sashes respectively. It will, of course, be understood that the wedge is first placed in position, 'at which time the plate 10 is turned down into angular relation to the wedge and then after the wedge 11 has been inserted between the meeting rails, the plate 10 is turned back against the vertical rail 18 of the window sash and the spurs I?) forced into the wood of the rail or bar. The hinge connection between the plate 10 and the wedge 11, permits the plate 10 to be forced rearward, even where meeting rails are of different widths. Furthermore, in detaching the device, it is only necessary to pull outward on the plate 10, thus releasing the prongs 13 from the vertical bar, whereupon the wedge may be readily withdrawn, the plate, in that case, acting as a.

handle. It will be obvious that when the device is in place, as shown in Fig. 1, it cannot be readily disengaged by the insertion of an instrument between the meeting rails of the sashes, as the hinge 12 will prevent any rotation'of the Wedge in the plane of the plate 10.

In concluding the description of the invention, I now desire to direct particular attention to the practical utility of my window lock. Obviously, the lock may be carried' by travelers and transients, and since it is composed of two hingedly united sections, will occupy a minimum space when in transit. In case the owner of the sash lock is lodging in a strange hostelry, he may guard himself against intrusion by applying the sash lock to the window. My sash lock is particularly employed for such' purposes since it may be so quickly and easily applied to-or removed from the window sashes.

Having thus fully described my invention,

what I desire to claim and secure by Letters Patent is 1. A sash lock adapted for temporary application to window sashes comprising an attaching plate having means whereby it may be secured in place, and a normally depending wedge block hingedly attached to the lower edge of the plate for movement in a plane at right angles to the face of the plate and the upper edge of the plate and from a depending position approximately depending position into angular relation to the face of the plate.

3. A sash lock adapted for temporary application to window sashes comprising an attaching plate having spurs upon its rear face adapted to. be temporarily embedded in the woodwork of a window, a hinge leaf hingedly connected to the lower end of the plate and movable in a plane at right angles to the face of the plate and to the lower edge of the plate, and a wedge block, t9 the butt end of which said hinge leaf '1 attached whereby the block is movable in a plane at right angles to the face of the plate.

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