rATENr SASI-I-LOGK.

To allwhomitmayconcern." f ,Beit known that'I, JAMns 0. LONG, a

bitizen of the United States, residing at Cedar Rapids, in the county of Linn and :State of Iowa, have: invented certain new and usefullmprovements in Sash-Locks;

and I dohere'by declare the following to be latch; for automatically moving into *a* keeper, for locking the window sashes-when they are moved into a closed position.

Another object of this invention is to provide a window look as specified, which includes a supporting plate, having a housing detachably mounted thereupon, in which is slidably mounted the locking latch, and further to provide a locking latch which is composed of a locking head having a reduced shank extending therefrom, Which shank is removably seated in a pulling member for unlocking the look, when it is desired to open the window.

A still further object of this invention is to provide an automatic acting sash lock, which is comparatively simple in construc tion, easy to manufacture, and which is du rable, the parts being interchangeable, upon the wearing out of any one of'the parts of the lock.

With the foregoing and other objects in view this invention consists in such novel features of construction, combination and arrangement of parts as will be hereinafter more fully described, illustrated in the accompanying drawings and claimed.

In describing the invention in detail reference will be had to the accompanying drawings wherein like characters designate like and corresponding parts throughout th several views, and in which a Figure 1 is a fragmentary section of a window, showing the lock applied thereto,

Fig. 2 is a plan view of the lock, showing the housing removed, 7

Fig. 3 is an edge view of the lock,

Fig. 4 is a longitudinal section on the line of Fig. 2, and.

Application filed June 4, 1915. Serial No 32,130.

Specification of Letters Patent. Patented 20, 19 9- i ig. 5 is a-perspective view of the latch pu l.

Fig. 6 is a perspective view-of a housing.

Referring more particularly to the drawings, .1 and 2 designate window sashes of'ordinary construction, which have mid rails 3 and 4. The mid rail 4' of the lower sash 2,

has a: metallic plate 5 secured thereto, by screws or analogous fastening devices, illustrated at 6.v The plate 5 is vprovidedx'with an upstanding tongue 7 formed centrally of its I ends, upon its rear Orouter edge. A shank 8 extends through a centrallyxdisposed opening formed in the tongue '7. The shank 8 is formed upon and extends outwardly from a latch head-.9, of ordinary shape, having one end 10 tapered. The shank 8 has its outer end externallyLscreW. threaded, as is shown .-at 11, for detachable connection with a pull member 12. The pull member 12 is positioned upon the opposite side of the tongue 7 from the head 9, and it has an upstanding curved finger engaging plate 14 formed upon its rear end. The plate 14 curves outwardly, so as to provide a concave surface for engagement with a finger of the operator of the latch. A spiral spring 15 is coiled about the shank 8, between the inner or butt end of the head 9, and. the inner surface of the tongue 7, and it tends to force the latch head 9 outwardly.

The plate 5 is provided with a plurality of spaced slots 16 extending therethrough upon each side of the head 9. The slots 16 are provided for receiving the tongues 17 which are formed upon the housing 18, for properly positioning the housing for inclosing the shank 8, spiral spring 15 and a portion of the head 9. The housing 18 has laterally extending wings 20 formed thereupon which engage the upper surface of the plate 5, and are secured to the plate, by the screws or analogous fastening means 6, by means of which the plate is attached to the mid rail 4 of the lower sash 2 of the window.

The mid rail 3 of the upper sash 1 has a keeper of ordinary construction mounted thereon, for receivingthe latch head 9, for locking the window sashes in a closed position.

When the sashes 1 and 2 are closed, the spring 15 will force the latch head 9 into the keeper 21 which is carried by the mid rail 4, and automatically lock the window. For unlocking the window, reparatory to opening the same, the latch 9 is moved eat Brion.

of the keeper 21, by pulling upon the pull member 12, which moves thelatch head 9 out of the keeper 21, against the tension of'the spring 15.

In reducing the invention to practice, certain minor features of construction, combination, and arrangement of parts may necessitate alteration, to which the patentee is entitled, provided such alterations are comprehended within the scope of what is claimed.

What is claimed is A sash lock comprising a plate having a pair of spaced apertures and pairs of spaced slots located in a plane within the apertures, a housing located on the plate and having each end open, tongues formed on the lower side edges of the housing and extending through the slots and bent at right angles to underlie the plate for securing the housing to the plate, a pair of oppositely disposed flaps formed on the side edges of the housing and having apertures'in registration with said apertures of the plate, fastening -elements extending through the aperslidahle in said opening, a latch head secured to the forward end of said shank and partially covered by said housing when in its normal position, a spring engaging the head and last named tongue for urging the head outwardly of the housing, a cylindrical member threaded to the'outer end of the shank and engaging the last namedtongue to limit the outward movement of the head fromthe housing and capable of adjustment on the shank to adjust the tension'of the spring,

and a finger grip on the cylindricalmember.

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