WINDOW-HOLDER.

Specification of Letters Patent.

Patented Apr. 21, 1914.

Application filed November 18, 1913. Serial No. 801,633.

To all whom t may conce/m.'

Be it known that I, ARTHUR A. MILLER, a citizen of the Unitedv States, residing at Kapowsin, in the county of Pierce and State of Washington, have invented certain new and useful Improvements in VVindow-Holders; and I do declare the following to be a full, 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.

This invention relates to window holders and has for its object to provide an improved device of this character which is designed for mounting` upon one of the side rails of a window-sash and constructed for engagement with the adjacent portion of the window frame so as to lock the sash when the latter is in an elevated position.

A further object is to provide a yieldable housing for the window frame engaging member whereby the latter will not become jammed, displaced or broken.

With these and other objects the present invention consists in the combination and arrangement of parts as will be hereinafter more fully described and shown in the drawings and particularly pointed out in the appended claims.

Like characters of reference designate corresponding parts in all of the figures of the drawings.

1n the `accompanying drawings :#Figure l is a fragmentary view of a window frame and sash showing my improved invention attached thereto; Fig. 2 is a vertical longitudinal section taken on the line 2-2 of Fig. 4, showing the frame engaging member in projected position; Fig. 3 is a similar view showing the frame engaging member in retracted position. Fig. 4i is a horizontal sectional view taken on the line Jr-1 of Fig. 2. Fig. 5 is a similar view taken on the line 5 5 of Fig. 3; Fig. 6 is a front elevation of my improved window holder showing the same attached to a window sash. Fig. 7 is a perspective View of the cam housing.

In its present embodiment my invention comprises a rectangular casing 1 having one end thereof open as at 2 and the other end closed by the end piece 3 which is formed integral with the bottom of said casing but which has its opposite ends cut therefrom, right angularly bent and secured by rivets to the sides of said casing. Attaching flanges 4 are formed on the lower edges of said sides and provided with perforations 5 for the reception of suitable fastening de vices 6.

To avoid the objectionable features connected with the ordinary sash fastener in which the window frame engaging member is pivotally mounted in the casing which latter when disposed on a loosely mounted window subject tc jars frequently causes said member to become jammed thus making it impossible for the operator to release the window when the same has heel? locked in elevated position, I provide a cam housing which consists -of a plate having a width substantially equal to that of the casing and bent intermediate its ends to form the upper and lower cam attaching ears 7 and 8. This housing is slidably mounted within the casing 1 and normally has the forward edges of the ears 7 and 8 in contact with the stops 9 formed on the sides of said casing adjacent the open end thereof. Said housing is yieldably retained in this position by the leaf spring 10 which has one end thereof secured to the inner side of the end piece 3 and the opposite end engaged with the head of a T-shaped slot 11 formed in the curved portion of said housing.

Pivotally mounted between the ears 7 and S on the pivot at 12 is a cam 13 which latter is disposed so as toV have the outer edge thereof projecting beyond the forward edges of said ears and through the opening 2 in said casing. For the manipulation of the cam 1.3 there is provided a bell crank 14: which is pivotally mounted in the casing 1 as at 15 and has the outer portion of one arm thereof projecting through a. transversely extending slot 16 formed in the closed end of the casing 1 said outwardly projecting portion being bent to a plane substantially at right angles to that of said arm to form a finger piece 17. The other arm of said bell crank is pivotally connected to one end of the rod 18 which passes through the shank of said T-shaped slot 11 and is pivotally connected at its opposite end to the lower edge of the cam 13.

From the foregoing, it will be seen that a. downward pressure on the finger piece 17 will draw the rod 18 inwardly thus retracting the cam 13. To normally retain the upper edge of the cam 13 in contact with the inwardly projecting tongues 19 which are cut from the ears 7 and S at diametrically opposite points thereon and which are intended to limit the outward movement of the cam 13, I employ a. helical spring 2O which encircles the rod 18 and has one end secured to the outer portion thereof and the opposite end in engagement with shoulders 21 formed by the shank of said T-shaped slot 11.

For convenience in operation I employ a radially projecting gripping member 22 which is eXteriorly secured to one side of the casing 1 adjacent the closed end thereof and adapted to co-act with said inger piece 17.

The operation of my improved Window lock is as follows Before raising the Windoiv the iinger piece 17 is depressed which compresses the spring Q0 and retracts the cam 13. The Window is then raised to the desired elevation after which the finger piece 21 is released, permitting the ca-m 13 under the infiuece of the spring 2O to come into engagement with the Window casing thus holding said Window in an elevated position.

From the foregoing description taken in connection with the accompanying drawings, the construction and operation of the invention Will be readily understood Without requiring a more extended explanation.

Various changes in the form, proportion and the minor details of construction may be resorted to Without depart-ing from the principle or sacricing any of the advantages of the claimed invention.

Vhat I claim is:

1. In a Window holder of the character described, the combination With a casing provided with attaching means and having one end thereof open, of stops adjacent said open end, a cam housing slidably mounted Within said casing, a cam pivotally mounted therein and having one edge projecting therefrom and through the open end of said casing, means Within said housing to limit the outward movement of said cam, means adapted to retract said cam, means connected with said last mentioned means to hold said cam in projected position and a spring to normally retain said housing in yieldable engagement with said stop.

2. In a Window holder of thc character described, the combination with a casing provided with attaching means and having one end thereof open, of stops adjacent said open end, a` cam housing slidably mounted within said casing, a cam pivotally mounted therein and having one edge projecting therefrom and through the open end of said casing, a pivotally mounted iinger press, a connect-ing member having one end secured to the inner end of said finger press, the opposite end thereof being secured to said cam whereby the latter may be retracted, means disposed upon said connecting member and adapted to hold said cam in projected position and a spring to normally retain said housing in yieldable engagement with said stops.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
