SPECIFICATION forming part of Letters Patent No. 621,569, dated March 21, 1899. Application iiled April 7, 1898. vRenewed February 14, 1899. Serial No. 705,512. (No model.)

To all whom it may concern: I

Be it known that I, JOHN WESLEY How- LAND, a citizen of the United States, residing at Lincoln, in the county of Lancaster and State of Nebraska, have invented certain new and useful Improvements in Sash-Fasteners; and I do declare the following to be a fu1l,clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention has relation to sash-fasteners 5 and the object is to provide a simple, durable, -and inexpensive device of this character by means of which the sash may be locked from the inside and eEectually pre-4 vent persons from without gaining entrance to the house through the window.

With this object in View the invention consists in certain features of construction and combination of parts, which will be hereinafter fully described and claimed.

In the accompanying drawings, Figure 1 is a perspective viewof a portion of the sash and window, illustrating the application of my invention. Fig. 2 is a detail view, partly in section, of the locking-cam and its casing, a portion of the casing being removed to illustrate the stop-lug. Fig. 3 is a detail perspective view of the cam removed from the casing, and Fig. 4 is a detail perspective view of the catch.

In said drawings, 1 denotes the windowsash, and 2 the window-frame.

3 denotes the cam-casing, which consists of two strips of metal 4 and 5, the strip 4 being arched and riveted to the strip 5. These strips have a slight spring action, and between the two is pivoted the cam-lever 6, which has upon its working face a fiat or rectangular portion '7, that engages the space 8 between the lugs 9, formed on the catch 10, that is se` Acured to the window-frame.

The front face of the plate 5 near one edge is formed with a lug 11, punched from the metal. When the handle of the cam is elevated to throw its square or rectangular face into engagement with the catch-plate, the handle of the lever presses by this lug due to the spring inthe plates. elevated a point above the lug the lug springs under the handle and holds it in its elevated position and the square portion of the cam in the catch, thereby securely holding the window-sash in locked position.

To unlock the window-sash, pressure is applied to the handle and it is forced downward, the spring-plates spreading apart to permit of the handle freeing itself from the stop-lug.

Having thus described my invention,what I claim, and desire to secure by Letters Fatent, is-
