FASTENER FOR THE MEETING-RAILS OF SASHES.

SPECIFICATION forming part of Letters Patent No. 510,432, dated December 12, 1893.

Application filed February 23, 1893. Serial No. 463.358. (No model.)

To all whom t may concern.-

Be it known that I, FREDERICK J. LOUDIN, a citizen of the United States, residing at Ravenna, county of Portage, State of Ohio, have invented a new and useful Window-Sash Fastener, of which the following is a specification.

This invention relates to that class of window-sash fasteners which employ a swinging lever on the upper bar of the lower sash and a catch on the lower bar of the upper sash, with which catch said lever engages for fastening the window-sash.

rlhe object of the invention is to secure greater safety and convenience, and a further object is to lock the lower sash in a raised position or the upper sash in a lowered position, by means of a detachable extension to the catch; all as more particularly described and claimed below.

In the drawings forming a part of this specication, Figure l is a broken perspective view, showing .the sashes fastened, neither one being raised or lowered. Fig. 2 is a vertical section of the fastener in Fig. 1, taken on line l-l, in Fig. 3, showing the sash locked when the lower one is raised or the upper one is lowered; and Fig. 3 is a plan view, with parts in section, on line in Fig. 2.

Referring to the lettered parts of the drawings A is the upper bar of thelower sash and B is the lower bar of the upper sash. To the bar B of the upper sash is attached an angled plate, C, fitting the upper and inner face of the same, and is provided with a catch, D, having an open notch, a, in the inner side, and an open, dovetailed mortise, c, in the top.

At E is an internally recessed casting, fitting the upper and inner face of the upper bar, A, of the lower sash, and attached thereto, as in Fig. 2. It will be observed that that part of the angled plate C which lits against the inner face of the sash, B, is provided with a rib or prongs, which impregn into the sash, and a like portion of the internally recessed casting E is provided with asimilar prong or ribs, O. The object of this is to prevent house breakers from forcing the plates by prying under the lower sash, which, but for the prongs or ribs, O, would be liable to draw the screws which fasten said plates to the sash. f

Placed on the internally recessed casting E is a turn-cap, F,having a pendent stern, G, which loosely passes down through a hole in the internally. recessed casting E, said stem terminating at the lower end in a key, II.

In the interior recess of the casting E is a swinging lever, I. Through this lever I and through the bottom of theinternally recessed casting E is formed a key-hole, J, Fig. 3, adapted to receive the key, 1I, of the stem, G. 'Ihe knob of the turn-cap, F, is preferably milled, as at e, in Fig. 1, to prevent theiingers from slipping when operating said turn-cap.

The turn-cap, F, is adapted to be raised and lowered so that when lowered, the key, H, will be partly in the key-hole in the lever I and partly in the key-hole of the internally recessed casting E, as in Fig. 2. Whenin said position the lever is locked, so that it cannot be swung in either direction to disengage it from the catch, D. By raising the turn-cap F, bringing the key, H, entirely in the key-hole of the lever l, and turning said turn-cap in either direction, the lever I can be swung out of or into the notch, a, of the catch D, the sashes being fastened, of course, when the lever I is in said notch, and unfastened when said lever is disengaged from the notch.

That portion of the internally recessed casting E which tits against the inner face of the sash is provided with one or more vertical ribs, L, (two being shownv in Fig. 3,) which loosely tit into corresponding grooves, c, Fig. 1, of that portion of the plate C contiguous to them. These grooves and ribs may be employed or not, as desired, their object being to serve as a guide, so that the parts of the fastener will register with each other, and to make it more difficult for a burglar to obtain access to the lever I, since he would have to saw through the ribs before he could saw the lever.

Referring to Figs. 1 and 2, P is a catch-extension, consisting of a bar having a series of notches, s, like those at o., in the catch D, and having one end formed so as to detachably t in the xnortise c, of the catch D, so as to ICO be located in an upright position, as in Fig. 2. When th'us employed the'upper or lower parts of the Window may be opened a desired distance and fastened in the same manner as when not Open.

When the catch-extension, P, is not enr ployed, it is caught into a notch, z, of the casting E, and placed horizontally on the window sash, as in Fig. l.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent of the United States, is-

1. A sash-fastener comprising the internally recessed casting for attachment to one of the sashes, a swinging lever in said recess, said casting and lever being provided with key-holes registering with each other,a turncap provided with a key adapted for vertical adjustment in said holes and to swing the lcver, and a catch-plate for attachment to the other sash and for receiving t-he end of the swinging lever; substantially as set forth.

0 A` sash-fastener comprising the internally recessedcasting for attachment to one ofthe sashes, a swinging lever in said recess, said casting and lever being provided with key-holes registering with each other, a turncap provided with a key adapted for vertical adjustment in said holes and to swing thele ver, and a catch-plate for attachment to the other sash and provided With the notched catch for receiving the end of the swinging lever, in combination with the detachable catch-extension; substantially as set forth.

3. In a sash-fastener, a swinging lever attached to one of the sashes, in combination with a detachable catch-extension attached to the other sash; substantially as set forth.

In testimony to the foregoing I have hereunto subscribed my name in the presence Of 4o two witnesses.

FREDERICK J. LOUDIN.
