IMPROVEMENT IN FASTENERS FCR THE MEETING-RAILS OF SASHES.

Specification forming part of Letters Patent No. 139,895, dated J une 17, 1873 application led May 2, 1873.

To all whom it may concern:

Be it known that I, MoRToN JUDD, of Wallingford, in the county of New Haven and State of Connecticut, have invented an Improvement in Win dow-Sash Fastenings, of which the following is a specification:

The object of this invention is to prevent the lever of the fastening being moved by a knife or thin instrument introduced between the meeting-rails of the sash. The swinging lever is made with a notch in 011e side to effect said object, and also with a curved end that carries the knob and turns aside clear of the sash, and allows the box containing the fulcrum of the lever to be made with a cap that is secured by the fulcrum pivot or screw.

In the drawing, Figure 1 is a plan of the fastening with the cap-plate in section, and Fig. 2 is a vertical section at the line w x.

The sash-fastening lever a is made with an eye at one end, through which the pivot-screw or rivet b passes to connect such lever to the plates c and d. The plate c is to be attached to the meeting-rail of the upper sash by the screws e, and upon such plate c is a threesided box, f, upon the upper edges of which the cap-plate d rests, and is secured by the said pivot b. The side of the box at 2 does not extend to the front edge of the plate c for a purpose hereafter named, but the pivot b is within a straight line drawn fromthe edge 2 to the edge 3 of the box f, so that the capplate d will be rmly held to the top edges of such box by the yscrew or rivet b. The eye of the lever a has three bearing-points for the spring h, so that the lever a will be held in the position shown by the full lines in Fig. 1, or by the dotted lines at 4, or back out of the way of the lower sash, as represented by the dotted lines at 5.

The shape of this lever c is peculiar, the end curving around and receiving the button k; the object of this being to allow the lever to occupy the space between the edge 2 ofthe box and the edge of the plate c, and throw the button 7c sufficiently back to be clear of the meeting-rail of the lower sash. This shape given to the lever a is also advantageous in keeping the button lc forward and over the locking-plate l, when the lever a is thrown to the extreme position, shown by full lines in Fig. 1. I remark that the lockingplate land the downward projection from the lever c are of usual character. A

The lever e hasV a projection, 6, forming a notch or angle at one side, and in case an eifort is made to move the lever a by a knife or other thin instrument introduced between the meeting-rails, the same enters this notch, and, in consequence of the lever not standing at right angles to the 'meeting-rails, any movement given to such lever will bind the knife against the meeting-rail of the lower sash in such a manner as to prevent further motion. Under ordinary circumstances the lever a will only be moved to the position shown by the dotted lines at 4, but when moved to the position shown by full lines, Fig. 1, it will be burglarproof.

I claim as my invention- 1. The sash-fastening lever a, made with the projection 6 at one side, in combination with the spring h, and bearing at the eye of the lever to hold the same in a position diagonal to the meeting-rails of the sash, for the purposes set forth.

2. The box f cast upon the plate c, in com' bination with the cap-plate d and rivet or screw b that secures said cap-plate and forms a pivot for the lever a, as set forth.

Signed by me this 22d day of April, A. D.
