IMPR'OVE MENT'IN"FASTENERS FOR THE MEETING-RAILS OF SASHE S.

Specification forming part of Letters Patent bio-175,1 [0, dated March 21, 1876; application filed February 19, 1876.

To all whom it may concern! Be it known that I, TRA eoT'rKARU'rz, of Brooklyn, E. D., in the county of Kings and State of New York, have invented a new and useful Improveinentin Sash-Fasteners, which improvement is fully set forth in the following specification, reference being had to the accompanying drawing, in which Figure 1 represents a front view of two window-sashes containing my improvement. Fig. 2 is a vertical central section of the same. Fig. 3 is a horizontal section in the plane a a, Fig, 2. Fig. 4 is a cross-section of the fastener, detached, in the plane y 3 Fig. 2. Fig. 5 is alike section in the plane 2 2, Fig. 2. Fig. 6 is an inverted plan view of the lockin g mechanism.

Similar letters indicate corresponding parts.

This invention relates to certain improve-- ments in fasteners for the meeting-rails of window-sashes; and consists of a novel construction and combination of parts, which will be fully hereinafterdescribed, and specifically pointed out in the claims. In the drawing, the letter A designates a 'bolt, oneend of which is provided with a spur,

B, which projects therefrom in a radial direction, and to the other end of which is secured a handle, O, by which-the bolt may be conveniently turned. This bolt is placed within a case, D, which is so made that it may be atfixed to a window-sash. The letter E designates catch-plates, two of which are in this example s'hown attached to one of two windowsashes, F F, one of the catch-plates being situated'near the so-called meeting-rail, and the other near the upper end of the sashF, so that the sash may be fastened in difl'erent positions. The catch-plates E are provided with holes at, having lateral branches of such a size as to admit the bolt A and its radial spur.

' Hence, if the case D is secured to the upper surface of the meeting-rail of the sash F, so that ,the end of the boltA projects in the direction of the other sash, F, and the catch plate or plates E are fastened in a line with. the bolt, the latter, by being pushed forward, enters the opening a in the catch plate or plates; and if the bolt is thereupon turned its radial spur B catches behind the catch-plate,

and by this means the sashes F F are drawn tightly against each other, while at the same time they are prevented from being raised or lowered. By drawing the sashes together they are prevented from rattling, and the window is made comparatively air-tight.

It is obvious that two or more catch-plates,

,E, may be cast in one piece, as shown in this example 5 or they may be cast separately, and fastened to the sash 111 any desired-manner.

In order to permit of locking the bolt A after it has been connected with the catch plate or plates E, I-combine with the bolt a lock of suitable construction; and the best form of mechanism which I have hitherto devised for this purpose consists in providing the bolt A with a flat or square part, G, Fig. 4, and arranging thereunder a locking-slide, H, the latter, by being moved under the square portion of the bolt, servingto prevent its rotation. To the slide H I have, in this example, connected a tumbler, I, which is subjected to the action of a spring, b, and so arranged that it, together with the slide B, may begrnoved by a key inserted through a hole,c, in the lock-case. The slide H and concomitant parts are arranged in a case, D, forming part of the case inclosing the bolt A.

By the locking-slide H the bolt A is not only prevented from turning, but also from being withdrawn afterit has been locked.

If desired, a device for preventing the withdrawal of the bolt A when it is disengaged from the locking-slide H may also be combined with the bolt, consisting of a groove, d, which extends partly around the bolt, and a second groove, 0, communicating with the first one, and extending longitudinally of the bolt. A lug, f, projecting inwardly from the bottom plate of the lock-case D, catches in the groove at when the bolt is turned after being disengaged from the locking-slide H, while the said lug traverses the longitudinal groove 6 when the bolt is moved backward or forward.

In the longitudinal groove e is placed a spring, 9, which bears on the lug f when the bolt is pushed back and forth, and by the frictional contact of this spring with the bolt the latter is-prevented from moving by accident.

What I claim as new, and desire, to secure by Letters Patent, is-

1. The combination of a locking-slide, H,

plate E, all substantiellyes and for the object specified.

In witness whereof I have hereunto set my TRAUGOTT KARUTZ. Witnesses CHAS. WAHLERS, J. VAN SANTVOORD.
