SASH-HOLDER.

SPECIFICATION formingpart of Letters Patent No. 764,305, dated July` 5, 1904.

` Application filed December 17, 1903. Serial No. 185,604?. (No model.)

T0 all whom, it may concern:

Be it known that I, Josnri-r L RIVER, a citi- Zen of the United States, residing at San Francisco, in the county of San Francisco and State of California, have invented certain new and useful Improvements in Sash Holders, of which the following' is a specilication.

My invention relates to improvements in sash-holders, the object of my invention being' to provide a cheap, simple, and convenient device for locking together the upper and lower window-sashes in any desired relative position.

My invention therefore resides in the novel construction, combination, and arrangement of parts for the above ends hereinafter fully specified, 'and particularly pointed out in the claim.

In the accompanying drawings, Figure I is a perspective view of a window equipped with my improved device. Fig. 2 is an enlarged perspective view of the device in its locking position. Fig. 3 is a similar View of the device in its non-locking position.

Referring' to the drawings, 1 represents the upper window-sash, and 2 the lower sash. Upon the upper edge of the lower sash close to one side of the window is secured the base 3 of a standard 4, said standard being forked to carry a pivot 5 for the swinging cam-lever 6. Said cam-lever is pivoted upon said staudard by means of an offset 7, which extends downwardffrom the main portion of the lever when the lever is in its locking position, as shown in Fig. 2. In one direction from said offset the lever broadens vertically and is provided with a wide curved head 8, forming a cam, said cam being arranged to engage the side of the upper window-sash. The construction and arrangement of this cam relative to the standard and pivot are such that if the cam is in engagement with the upper sash and it is attempted to open the window by either sash then the cam-shaped head 8 binds more firmly against the face of the upper sash and effectually locks the same against any further In the opposite direction to the head 8 the lever extends to form an arm l0, carrying' at its extremity an eye 1l, to which is attached a cord l2,

which is preferably passed through a small staple 13, secured at a convenient point in the lower window-sash.

This holder has been especially devised for convenience of manipulation in view of the fact that the holder itself being' on the top of the lower window-sash is very often at a considerable height and out of convenient reach of the hand. This is especially the case with large windows in offices, churches, or other large buildings. The construction is such that the device can readily be operated without the necessity of reaching up to it with the hand or with a stick or pole. This utility is due to the fact that the cam-lever is pivoted to the standard by means of the offset and also that the end of the lever which carries the head is considerably heavier than that to which the string is attached. The utility of this construction will be seen by following the mode of operation of the device. Supposing that the window-sashes are locked when open and it is desired to close the same, the holder does not oppose the closing of the windows, since the cam only binds in the opposite direction to that in which the sash moves when closing. However, into whatever position the window-sashes are moved the cam immediately drops back into place, locking the same against any further opening movement thereof; but if it is desired to open the sashes farther this can be easily done from the inside by y drawing down the string slightly, raising the Vcam-head out of engagement with the upper sash, opening the desired sash, and then letting the cam-head drop into position again, which it does at once on account of the weight of the cam-head; but it may occasionally be desired to throw the cam-lever permanently out of engagement with the upper sash. When this has been done, it would be inconvenient to restore it to its locking position but for the fact that, first, the cam-head is heavier than the opposite end, and, secondly, that the lever is pivoted to the standard by means of the otl'set, for by reason of the latter construction an upward movement of the lower sash followed by a sudden stoppage of the same will impart momentum to the cam -lever sufliciently to throw it over into its locking posicam-head is uppermost, and pivoted by said offset to the standard, substantially as described.

In witness whereof I have hereunto set my -15 hand n the presence of two Subscribing Witnesses.

J. L. RIVER.
