CHARLES M. BURNS, JB., OF PHILADELPHIA, PENNSYLVANIA.

SASH FASTENER.

SPECIFICATION forming part of Letters Patent No. 226,033, dated March SO, 1880, Application filed February 3, 1880.

To all whom it may concern:

Be it known that I, CHARLES M. BUnNs, Jr., of Philadelphia, State of Pennsylvania, have invented certain new and useful Iniprovements in Sash-Holders, of which the following is a speciiication.

Mv invention relates to improvements in dei vices intended to hold and secure such objects as two sliding sashes of a window in position when said sashes are closed, and to prevent their being opened from the opposite side to that ou or to which the catch is applied; and the object is to enable a person to disconnect the parts and move either sash with one hand, if desired, and is an improvement upon the device for which I obtained Letters Patent No. 116,150, dated June 20, 1871.

My invention consists in combining with a sash-holding spring-catch a latch or tumbler pivoted to said spring-catch, and adapted to engage with the frame of the device and :retain said catch within its frame, and thus allow the sashes to be disconnected and moved.

In the drawings, Fi gure'l represents,in perspective, a front and rear view of the device with the spring-catch as pushed in and retained within its frame by the latch or tumbler; Fig. 2, a perspective view of the device with the spring-catch projecting forward or sprung out, as when it has passed the top of a sash and locked it securely. Fig. 3 represents a having the spring-catch and latch within the frame thereof in a position occupied while the sashes are passing each other; Fig. et, a vertical section of the device with the parts in the same position as shown in ig.1. Fig.5 represents a perspective view of the frame of the device; Fig. 6, a perspective view of the catch disconnected from its frame and late In the drawings, A represents the plate or frame of the device, adapted to be set and secured by screws passing through the holes a in a mortise formed in the wood of a windowsash or the frame thereof. This plate is provided at the back with two lugs, B, recessed at b, for the reception of one end of the catch D, and, furthermore, recesses b', intended to provided with semicircular form sockets to receive the ends of a projection or boss, 1,011 the rear of said catch D. This catch is adapted to move through the slot A' of the plate A, and is retained in position by the lugs B and by the spring e abutting against its upper end, forcing it into the recesses in said lugs.

As a bearing-surface for the catch upon the top of the opposite sash to which it is or may be fastened a small plate is generally countersunk into said sash to prevent its abrasion.

To retract and retain the sprin g-catch within its frame, and allow one sash to pass in front of the other, this catch had to be pushed back with a finger of one d of the person desiring to open the window while the sash was being lifted with the other. This operation is often inconvenient.

To remedy this defect I pivot to the side, but toward the rear, of the spring-catch, at f, a latch or tumbler, Gr, made, preferably, of sheet metal, and adapted to pass loosely and play vertically through a slot formed between the catch and its frame by recessing either one or both, This latch G is formed with a nearly triangular pendent projection, g, to engage with the rear of the plate A, as shown in Figs. 1 and 4, and ret-ain the catch out of the way of the adjoining sash. The free end g projects out then a short distance above the lower end of the catch, and is lifted by the passing sash, which releases the catch and brings the position shown in Fig. 3, in which position the catch is maintained by said passing sash, and the latch is left with its point g resting upon the bottom a of the slot made in the plate A for its reception, and kept from falling back out of position by the shoulder d' on the upper end of the catch.

VVheu the sash is lowered to close the window the catch is forced out over the edge oi the adjoining sash in the position shown ir Fig. 2 by the spring e, and thus both sashe: are secured. The catch is kept from spring ing out too far by a projection, cl2, on its lowe end abutting against the inner face of th plate A of the device.

I am aware that keys and other movabl devices have been used to retain a sash-hol( ing spring-catch out of the way of an ascem ing sash; but they differ in construction from vided with a projection, g, adapted to pass 1o mine, and are generally liable to become dethrough a. slot in said plate and engage theretaehed and lost or misleid. with, substantially as and for the purpose de- Having now fully described my invention, scribed. 5 what I claim, and desire to secure by Letters P CHARLES M. BURNS, JR.
