SASH=FASTENER.

SPECIFICATION forming part of Letters Patent No. 356,182, dated January 18, 1887.

- Application iilrd July 3, 1856. Serial No. 07,090. (Model.)

To all whom t may concern:

Be it known that we, J oI-IN Wnrrn'and GUs THoMils, citizens of the United States of America, residing at Fulton, in the county of Obion and State of Tennessee, have invented certain new and useful Improvements in a Vindow or Sash Lock, of which the following is a pivoted above the center to a seat secured on` the window-sash in such .a manner that the lower end will hang perpendicularly from the pivot, while the upper end protrudes forward, so as to engage with stationary studs arranged in the window-frame- It also consists in the inode of mounting such fastener so that the lower end will hang vertically from the pivot along close to the windowsash, while the upper end protrudes forward sufficient to engage with the stop studs.

it also consists in providing said fastenerwith catching-lugs at each end, and, when V.desired, with double lugs at the upper end,to prevent the window Vfrom being accidentally displaced; also, in the manner of securing such fastener to the windowsash and engaging it with the stopstuds, also, in the mode of operating the same.

Figure lis an open window, shoi'ving the fastener on the lower sash, as well as the engaging stop-studs in the window-frame. Fig. 2 is a vertical cross-section of the saine, taken at the dotted lines a: a, showing the fastener engaged. Fig. 3 is a fragment of the edge of the window-sash, showing the fastener enlarged, being an edge elevation. Fig. 4 is another fragment of a window-sash, showing the fastener in detail, being a plan view of the same. Fig. 5 is another fragment of a window-sash, showing a modified form of the fastenerin detail, being also a plan view.

Similar letters of reference indicate corresponding parts.

A is awindow-frame. B B are window-sash. a is a window-fastener, pivoted at c. is a metal seat, secured to the window-sash B by screws b l), to which the fastener is pivoted;

and d d d and g are stop-studs set in the side of the window-frame A, with which the window-fastener a engages to secure thewindow in place.

The metal fastening-bar c, which need not exceed threeinches in length, a quarter of an inch to th rce-eighths in width, and a sixteenth to an eighth of an inch in thickness, assumes in form an obtuse angle, the pivotal center c being the corner. At each end of the fasteningbar a, on opposite edges, is a truncated lug or catch, n o, preferably slightly hooked for engaging with the stop-studs d d g, to fasten the window open or closed, respectively. For the purpose ofsafety we prefer to use two lugs, n u, on the upper end ofthe fastening-bar c, as seen in Fig. 5.

rilielo wer portion offastening-bar c is longer and heavier than the upper portion, so that when pivoted in its seat the lower portion will pend vertically close along the sash, thereby thrusting the upper and shorter portion forward to engage with the stop-studs d to keep the window open.

Anything to which the fastener a can be pivoted that may be fastened to the window-sash will serve as the seat i for the fastening-bar a, provided it is permitted to move freely.

The studs d d d are introduced at suitable intervals into .the window-stops by the side of and at a suitable distance from the sash to allow the catch-lug n on the upper end of the fasteningbar a to engage naturally therewith. The stud gis introduced lower down in the window-stop, close to the sash, in such a position that when the window is closed the lug o on the lower end of the fastening-bar a will naturally engage with it and fasten the window closed.

It will be observed that the fastening-bar a able mischief is by this device and mode of fastening windows wholly overcome, and so, too, is the danger of leaving the Windows uufastened through carelessness or by accident, as this fastener works automatically. The Window cannot be closed Without being` fastened, unless through design.

Having new fully described our invention, what we esteem as new, and seek to secure by Letters Patent, is-

l. A pcudulous elbow-shaped double latch in one piece having; a pivotal point above the center, and Whose opposite arms form an obtuse angle to cach other from the pivotal point and are provided with catches near their ends on opposite edges, and adapted to go over catches for the purpose ol' locking, substantially as shown and described.
