IMPROVEMENT IN FASTENERS FOR MEETING-RAILS OF SASHES.

Specification forming part of Letters Patent No. 161,020, dated March Q3, 1,875; application led February 6, 1875.

To all whom tt may concern:

Be it known that I, EDWARD G. FELT- HoUsEN, of the city ot' Buffalo, in the county of Erie and State of New York, have invented certain Improvements in Sash-Locks, of which the following` is a specification:

My invention relates to that kind of sashfastenings known as meeting-rail sash-locks, which consist generally of an arm pivoted to the upper side ofthe meeting-rail ot one sash, so as to swing horizontally and project over the opposite rail of the other sash.

The object of my invention is to protect the locking-arm against movement by an instrument from the outside inserted between the meeting-rails for the purpose of unlocking the sash; and with this object in view, my invention consists of a gravity locking-catch, adapted to drop over the locking-arm, and provided with a suitable shoulder to prevent the arm from being returned, as will be hereinafter more fully set forth.

In the accompanying drawings, Figure l is a plan View of asash-fastening provided with my improvements. Fig.'2 is afront elevation, and Fig. 3 a side elevation, thereof.

Like letters of reference designate like parts in cach ofthe figures.

. A represents the lockingarm ot' the fastening, pivoted to a bearing-plate, B, secured by screws to the top ofthe meeting-rail of the upper sash, in a common manner. C is a plate secured to the opposite meeting-rail, and provided With a curved ledge, o, with which a notch, a, on the under side of the locking-arm engages as it is swung around, for the purpose of drawing the sash together to prevent rattling of the same, which is, however, an old feature of construction. D is my gravity locking-catch, pivoted to au upwardly-projecting lug, e, cast with the plate O. The catch D is provided with a jog or lockingshoulder, d, and its end or face is beveled on the under side, so as to cause the locking-arm, as it is swung around, to strike against this incline and swing upward the catch, until the arm has reached its locking position and passed the shoulder d, when the catch descends to its former position and locks the arm, as clearly shown in Fig. 2.

As represented in the drawing, the upper side of the arm A, at the point Where it engages with the catch D, is recessed and beveled off, so as to facilitate its engagement with the catch and render the device more compact. The lug e, which forms the bearing ot' the catch D, also serves as a stop to arrest the movement ot' the arm A, when it has arrived at its proper locking position. The lockingarm is readily released by raising the catch D with one n ger, when thearm can be readily swung around from disengagement with the meeting-rail in the common manner.

Vhat I claim as my invention is- The combination, with the pivoted arm A, of the gravity locking-catch D, pivoted to lug` e, and provided with a suitable shoulder, d, substantially as and for the purposes hereinbefore set forth.

EDWARD Gr. FELTHOUSEN.
