SASH HOLDER AND LOCK.

Specification of Letters Patent.

Patented Nov. 9, 1909.

Application filed March 1, 1909. Serial No. 480,732.

To all whom it may concern:

Be it known that I, THEODORE KEPHART, va citizen of the United States, and a resident of Sinnamahoning, in the county of Cameron and State of Pennsylvania, have invented a new and Improved Sash Holder and Lock, of which the following is a full, clear, and exact description.

The invention relates to windows and its object'is to provide a new and improved sash holder and lock, arranged to hold the upper and lower sashes in an open position or to securely lock the sashes in place when closed.

For the purpose mentioned, use is made of upper and lower runners fixed on a window frame, and spring lever devices held on the sashes and adapted to engage the said runners, to hold the sashes open by frictional contact, the said spring lever devices and runners having interlocking means for locking the sashes in a closed position.

A practical embodiment of the invention is represented in the accompanying drawings, 10i-ming a part of this specilication, in which similar characters of reference indicate corresponding parts in all the views.

Figure l is a front elevation of a window provided with the improvement and showing the upper and lower sashes closed; Fig. 2 is a transverse section of the same on the line 2 2 of Fig. l; Fig. 3 is a similar View of the same on the line 3--3 of Fig. l; Fig. et is an enlarged cross section of the same on the line i-4 of Fig. l; and Fig. 5 is a side elevation of the lower runner.

The lower and upper sashes A and B are mounted to slide up and down in the usual manner on a window casing C, and on the lower cross bar of the lower sash A is pivoted a hand lever D pivotally connected with one end of a link E, mounted to slide in a bearing F attached to the lower sash A, and the outer or free end of the lin E is provided with a vertically-disposed spring arm E, adapted to engage a vertically disposed runner G, provided with pointed angular terminals G adapted to be driven into the stop bead C of the window casing C, to hold the runner G fixed on the window casing. The lower end of the runner G is provided with a shoulder G2 in register with the upper end of the arm E at the time the lower sash A is closed, so as to lock the sash A in a closed position at the time the lever D is swung downward, as indicated in Fig. l. Now when it is desired to raise the lower sash A, the operator swings the hand lever D upward, thus moving the link E to the left and the arm E out of engage nient with the shoulder G2, to unlock the sash A and allow the operator to raise the sash by having hold of the lever D. lVhen the sash has been raised to the desired height, the operator swings the lever D downward, so as to move the link E to the right and thus press the spring arm E in i'irm Contact with the runner G, and owing to the flexibility of the arm it will engage the runner with suilicient force to hold the sash A in a raised position. When the lever D is swung into the position shown in Fig.

l, the end of the link E connected with the lever is below the pivot of the lever so that` the lever is locked in this position and the spring arm E of the link E held in engagement with the runner. The runner G eX- tends suliiciently high on the casing C to permit the arm E to engage the runner at any point to which the sash A may be raised by the operator.

On the upper cross bar of the upper sash B is pivoted at H a spring lever H having an arm H2 extending from the pivot H outwardly to the left side of the window casing C, as plainly indicated in F ig. l, the said arm H2 being guided in a guideway I in the form of a staple or the like, attached to the upper sash B. From the arm H2 extends transversely and lforwardly an arm H3 adapted to engage a runner J secured to the stop bead C2 on the left side of the window casing C. The forward end of the arm H3 terminates in the downwardly-extending member H4 of the lever H, and this member H4 is provided with an oii'set or a shoulder H5, adapted to engage the lower angular terminal J of the runner J and above the o-set or shoulder H5 the member H4 is pro vided with a projection H0 adapted to pass under the runner J for a purpose hereinafter described. It is understood that the angular terminals J and J 2. of the runner J are driven into the window casing C, but the runner J is somewhat spaced from the stop bead C2, to allow of engaging the odset H5 with the angular terminal J', as indicated in Figs. l and 2. When the upper sash B is in a raised or closed position, the offset H5 engages the terminal J of the runner J, to lock the upper sash B against downward movement. Then it is desired to lower the upper sash B the operator swings the member H4 of the lever H forwardly, to disengage the odset H5 from the runner J, and then the operator swings the lever H to the right into the position shown in dotted lines in F ig. l, so that the sash B can be moved downward, by the operator having hold of the lower end of the lever H. IVhen the sash B has been lowered the desired distance then the operator swings the lever H to the left into engagement with the runner and then the lever is forced inward toward the sash to cause the projection H6 to pass under the runner, when the sash will be held in the position to which it has been moved by the friction of the said lever with the runner.

From the foregoing it will be seen that the spring lever devices for both the lower and upper sashes A and B serve to lock the sashes in a closed position, and to hold the sashes in open position by frictional contact of the arms E and H3 engaging the runners G and J, respectively.

The device shown and described is very simple and durable in construction, and can be readily applied to sashes and window frames as now constructed.

Having thus described my invention, I claim as new and desire to secure by Letters Patent:

1. A. sash holder and lock, comprising a vertically disposed runner for attachment to the window casing, a spring lever device on to hold the sash raised by frictional contact,

the said spring lever device and the said runner having interlocking means in register with each other at the time the sash is closed to lock the sash in the closed position.

2. A sash holder and lock, comprising a vertically disposed runner provided with a shoulder and secured to the window casing, a lever fulcrumed on the window sash, a bearing on the window sash, and a link connected at one end with the said lever and provided at the other end with an arm for engagement with the said runner and the shoulder thereof.

3. A sash holder and lock, comprising a vertically disposed runner having a shoulder and secured to a window casing, a lever fulcrumed on the window sash, a bearing on the sash, and a link connected at one end with the lever and provided at its free end with an upwardly projecting spring arm for engagement with the runner.

In testimony whereof I have signed my name to this specification in the presence of
