UNITED STATES PATENT QF-FICE.

WILLIAM E. MORRISON, OF GRANITE CITY, ILLINOIS, ASSIGNOR OF ONE-HALF TO ISRAEL B. EURWI'IZ.

WINDOW FASTENER.

This ,invention relates to an improved article of hardware which may be conven- .iently and specifically designated as a window sash holder or fastener. I x The invention has more specific reference to a device of this kind which is mount ed upon the top of a lower slidingsash and is cooper-able with the lower portion of the upper sliding sash for preventlng unauthorized opening of the sashes from the outside of the window.

The details of the structure and their relative arrangement and association will become apparent from the following description and drawings.

in the accompanying drawings forming a part of this application, and in which like numerals are employed to designate like parts throughout the same:

Fig. 1 is a fragmentary vlew of a portion of a window showing the improved sash holder in operative position.

Fig. 2 is an enlarged side view in section and elevation showing the specific construction of the holder more plainly.

In carrying out the invention, I employ a mounting bracket 1 which in the present instance comprises an attaching base 2 having upstanding ears 3 through which a pivot pin or bolt 4 extends.

Pivotally mounted upon the bolt 4 is the improved retainer generally indicated by the reference character 5. This retainer comprises a substantially U-shaped member having a short arm 6 pivoted upon the pin 4: and a long arm 7 extending outwardly beyond the window frame as shown.

The intermediate portion or bight of the U-shaped member is in the form of an arcuate plate 8 carrying a corrugated rubber facing 9. Attached to the free end of'the arm 7 is a depending operating chain 10 having a finger piece 11 at its bottom. in addition,

a curvilinear or bowed spring 12 is fastened at one end to the base portion 2 of the attaching bracket and has its free end portion overhanging and bearing upon the arm 6 at a point spaced from the pivot connection of the same.

Under normal conditions, the spring 12 serves to yieldably hold facing 9 in locking contact with one of the side rails of the upper sash 13 when the bracket 1 is fastened upon the top of the lower sash 14 as shown. Because of the peculiar shape and location of the device, it is obvious that when thus positioned, it is impossible to .push the upper sash 13 down or to lift the lower sash 14 up. It is obvious, though, that if the upper sash has been lowered somewhat and it is desired to raise and close it, this can be done without interference of the locking device. "This isalso true of the I lower sash; that is, if it has been raised slightly it can be lowered to closed position Without interference of the device. It is also obvious that the operator may, at any time, pull upon the operating chain 10 to temporarily hold the device out of operation when the sash is to be raised or lowered as may be desired.

With the device shut, however, considerable difliculty would be experienced in attempting to open the sashes from the interior. It is also evident from the foregoing description that I have evolved and pro I duced a comparatively simple and inexpensive lock that can be ut in place by unskilled hands. Although it inds severel ,it nevcrthe}lless does not mar or destroy t e Window sas The tighter the push against the sashes, the tighter'the device binds. The device is not unsightly in' any instance and has proven to be successful in operation after considerable actualnse.

The foregoing and other features and advantages of the invention have doubtless been made appai'ent by the description and drawings. Moreover the description will suffice, when taken in connection with the drawings, to enable persons skilled in the art to obtain a clear'understandin of the inven tion. Therefore a more lengt my description is thought unnecessary,

While the preferred embodiment of the in vention has been shown and desfi'ibed, it is to be understood that minor changes coming within the field of claimed invention may be resorted to if desired.

Having thus described my invention, What I claim as new is The herein described sash fastener comprisin a bracket, a vertically swingable U- shape retainer having an arcuate toothed bight portion adapted for use in opposed re lation to a window sash and also having at the lower endof said arcuate lower arm pivoted at its en remote from the arcuate portion to the said bracket, and

ortion a short further having a long arm extending in the same vertical plane as the lower arm from the upper end of the arcuate portion and overhanging and spaced from the lower arm and the bracket and extending beyond the pivoted end of the lower arm and the bracket, a string or cable connected to and directly pendent from the end of the long arm, and a bowed spring attached to the bracket below the pivot connection of-ihe lower arm of the retainer and extending upwardly from the point of connection and,

outwardly beyond the pivot connection of the lower arm and having a free end portion overhanging the pivot connection and the adjacent portion of the lower arm of the retainer and exerting a downward pressureon said lower arm; -said free end portion of thespring resting in the space between the lower and upper arm, whereby it is protect- 20 ed by the upper arm.

In testimony whereof I- afiix my signature.

WILLIAM E. MORRISON.
