SASH-FASTEN ER.

SPECIFICATION forming part of Letters Patent No. 688,003, dated December 3, 1901.

Application filed July 29, 1901. Serial No. 70,045. (No model.)

To a whom. it 77mg concern.-

Be it known that I, HENRY L. NORTON, of Middletown, in the county of Middlesex and State of Connecticut, have invented a new and useful Improvement in Sash-Fasteners; and I do hereby declare the following, when taken in connection with the accompanying drawings and the letters of reference marked thereon, to be a full, clear, and exact description of the same, and which said drawings constitute part of this specification, and represent,

Figure 1, a side view of a fastener constructed in accordance with my invention; Fig. 2, a rear view of the same; Fig. 3, a side view, the reverse of that shown in Fig. 1; Fig. 4, a side view, the same as shown in Fig. 1, with the cap of the case removed; Fig. 5, a broken view of the slide and its finger-piece pivotally connected thereto and shown offset therefrom; Fig. 6, an end view of the arm of the operating-slide; Fig. 7, a broken top view showing the securing-flange of the case; Fig. 8, a sectional view showing the safety-plate therefor; Fig. 9, a perspective view of the safetyplate detached.

This invention relates to sash-fasteners,and is an improvement upon the fastener for which Letters Patent of the United States, No. 614,336,were granted-to me November 15,1898, the objects of the invention being to simplify the construction of the fastener, to improve the operation, and to provide the same with an operating-handle which may be conveniently grasped; and the invention consists in the construction as hereinafter described, and particularly recited in the claim.

Like my previous fastener, the case or frame will be formed in two parts, the case A and cap B being substantially the same in external appearance as in my previous patent and riveted together to form the case, except that the clearance-notch for the finger-piece on the plate is enlarged to permit it to be more readily grasped. Within the case upon a collar a, which is mounted upon a rivet b, is hung a locking-lever C,, formed at its upper end with a nose D and at its rear with a downwardly-extending leg E, the lower end of which is curved and which terminates in a toe f, having a flat under surface. The space between the leg E and the body of the lever is formed with a lug or shoulder F to receive one end of a spring G, the other end of which bears upon the upper face of an L-shaped partition H, formed in the case, the said partition extending to the forward edge of the case parallel with the bottom wall thereof.

The lever is formed upon one-side, and preferably upon the right side, with a finger-piece I, which projects through a notch J, extending inward from the rear wall of the case. Opposite thenotch J in the cap Bis formed a similar but shorter notch J. E of the locking-lever is a slide K, guided for transverse movement in the case and formed with a forwardly-projecting arm L, which extends forward between the partition H and the bottom of the case, the said arm terminating in a head M, forming a bearing for one end of a spring N, the opposite end of which is seated against a shoulder N in the case. This slide is formed at its inner face with a projection is, which has a flat edge m. In order that the slide may be readily grasped by the fingers, the central portion of its rear end is cut away, leaving shoulders n, between which the link 0 is pivoted, and this link is connected with a finger-piece P by a link Q. The parts being so connected with the finger-piece may be readily turned to one side or the other, as required. This construction is desirable, as my fastener requires two operations to unlock it, and to do this conveniently requires the operator to use both hands. Oftentimes a fastener stands so close to the window frame or sash that it is inconvenient to grasp the slide; but by connecting the finger-piece with the slide with links whereby it may be turned to one side, as clearly shown in Fig. 5, the finger-piece may be readily grasped and the slide operated. Preferably the head M will be formed integral with the arm L and so notched on opposite sides, as shown in Fig. 6, that the spring N may be readily turned onto the arm; but it is apparent that the head might be formed independently and riveted to the arm.

Fasteners of this character may be employed for locking sashes together at difierent points, so that either the upper sash may be lowered or the lower sash raised. \Vith such fasteners it is possible to reach over the upper sash and remove the screws by which the fastener is so- In the rear of the leg cured,and this might be done when it would'be impossible for the person outside the window to reach over and unlock the device, which, as before stated, requires two operations and the use of both hands. To avoid this, I employ a plate R,corresponding substantially in form to the flange R of the case, by which it is socured in position, and this cap is held in place by a short tack or nail S, adapted to extend through the plate and flange into the meeting-rail of the sash and so as to cover the retaining-screws.

The operation of my improved fastener is the same as my previous one, the lever being locked in either its projected or retired position and requiring the Withdrawal of the slide K before it can be retired.

Having thus described my invention, What I claim as new, and desire to secure by Letters Patent, is

In a sash-fastener, the combination with a case, of a locking-lever pivot-ally mounted at its lower end therein, and provided at its upper end With a nose projecting forward through the front of the case, and with a downwardly and rearwardly extending leg, an operating-slide longitudinally movable in the case, and formed with a projection at its inner end for engagement with the said leg, a finger-piece coupled with the outer end of said slide by links whereby the finger-piece may be turned out of line with said slide, substantially as described.

In testimony whereof I have signed this specification in the presence of two subscribing witnesses. A

HENRY L. NORTON.
