SPECIFICATION forming part of Letters Patent No. 608,102, dated July 26, 1898. Application filed February 16, 1898. $erial No. 670,572. (No model.)

T0 at whom it may concern.-

Be it known that I, LEWIS H. BOWMAN, of Walla Valla, in the county of W'alla WValla and State of WVashington, have invented a new and Improved Sash-Fastener, of which the following is a full, clear, and exact description.

My invention relates to an improvement in sash-fasteners, and has for its object to lock the sash in any desired position and also to hold it securely against rattling and to make a tight joint which will prevent the passage of air between the sash and the casing.

The invention consists of certain features of construction, which will be hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forminga part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure 1 is a cross-sectional elevation taken through the window-sash. Fig. 2 is a similar view showing the lower part of the sash and window-sill with the fastening mechanism in a different position. Fig. 3 is a top plan view inserted in the sill and the operating-lever, and Fig. 4 is a sectional elevation taken upon the line 4. 4 of Fig. 1.

My invention is particularly designed for use in connection with the windows of railway-cars, but is applicable to windows of any sort.

In the drawings the window-casing is represented by O and the sash by A. This sash may be constructed in any suitable or desirable form.

Just inside the sash is placed a lockingframe D, of such a Width as to fit snugly between the two sides of the casing and of a length slightly less than the inside measurement of the casing. This frame is pivoted to links cl, which are pivoted at one end of the casing C. The end of the link nearest to the sash is the one which is pivoted to the locking-frame D, and the opposite end is pivoted to the casing 0. It will be seen that when the frame D is moved upward it will be swung away from the sash A and released, while when the frame is pulled downward it will be swung into close engagement withthe sash and bind it in place. The inner edge of the frame D has a rubber strip K, adapted to form a tight joint with the sash A. This locking-frame D is operated by means of the connections shown beneath it, which connections are inserted in apocket or recess 13 in the window-sill B. A rod J, threaded at its upper end, passes through a hole in the lower bar of the frame D, and the frame is secured to said rod by means of nuts J, located above and below the lower bar of the frame. The rod J is pivoted to links I, which at their lower ends are pivoted to a horizontal lever H. "This lever 11 is pivoted at or near its middle to a" bracket 6, depending from the lower surface of the plate E, which is placed inthe window-sill so as to cover the recess B formed therein.

A bracket 5 depends from the lower surface of the plate E and furnishes a pivot for the lever F, by which the mechanism just described is operated. This lever is provided with a downwardly-extending arm F, the lower end of which is pivoted to the bracket 6. The lever F is provided with an extension f, extending beyond the arm F, and the end of this extension is beveled somewhat, as clearly shown by the dotted lines in Fig. 2.

The plate E is provided with a slot adapted to receive the lever F. The extension f of the lever F serves to fill up the slot when the lever is thrown down to the horizontal position or that shown in Fig. 1. This slot must extend beyond the pivot of. the lever F in order to permit the lever to be thrown into its upper position, as shownin Fig. 2, and the extension f of the lever will fill this space when the lever is thrown into locked position. The lever F is connected with the lie ver H by means of links G, pivoted to the end of the lever H and to the downward extension or arm F of the lever F, the. latter pivot being located above the point where the lever F is pivoted to the bracket e.

The parts are formed in suchproportion that when the lever F is thrown down to the horizontal or locked position the pivots will all be substantially in line. Preferably the pivot upon which the lever F swings will be a little to one side of the line connecting the other pivots and upon that side in which the strain upon the links G will tend to hold the parts in their locked position. As shown in Fig. 1, this would be a little to the right of the center line connecting the end pivots.

The lever F is provided with a knob f, by which it may be conveniently engaged for locking and unlocking the lever. By engaging this knob the lever may be thrown upward into the position shown in Fig. 2. The result of this will be to raise the frame D and thus to swing it away from the sash A. This frees the sash and enables it to be raised to any point desired, where it may be secured by depressing the lever F and thus forcing the frame D firmly against the sash.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patent- A sash-holding device, comprising a vertically-moving sash-locking member, a horizontal, pivoted lever beneath the windowsill, connections from one end of said lever to the sash-locking member, a bent hand-lever pivoted by one end beneath the sill and. having an arm lying flush with the sill when the window is locked, and a link connecting said lever near its bend with the other end of the first-named lever, the pivots on the hand -lever and its connected link being nearly in line when in the locked position, the center pivot being sufficiently at one side of the center line to hold the parts locked, substantially as described.
