INVENTOR v 1 :MZLcmL UNITED STATES PATENT \VILLIAM J. BARRON, OF HUNTSVILLE, ALABAMA.

SASH-FASTENER.

SPECIFICATION forming part of Letters Patent No. 325,481, dated September 1, 1885.

Application filed December 4, Iss4. (No mo lcLi To all whom it may concern:

Be it known that I, XVILLIAM J. BARRON, a citizen of the United States, residing at Huntsville, in the county of Madison and State of Alabama, have invented certain new and useful Improvements in Sash-Locks, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.

The nature of this invention is a windowsash lock which consists in the combination of an angular catch-bolt, a sliding spring-controlled rack and pinion, and means for rotating said pinion in order to retract said catch-bolt from aslot or recess in the stile of the sash when it is desired to raise or lower the latter, into which recess it is projected by the force of a suitable spring, as hereinafter particularly described, and shown in the annexed drawings, of which- Figure lisa perspective view of the exterior of the lock detached from the window-frame. Fig. 2 is a like view of the same reversed, the plate 2', Figs. 1 and 4, being removed to reveal the interior mechanism. Fig. 3 is a side elevation of a windowframe, showing my device applied thereto. Fig. 4 is a horizontal section, as on line a b, Fig. 3.

Like letters of reference, where they occur in the several figures, indicate the same parts.

A marks the frame of the lock, which in the present instance is L-shaped, the wing of which that comes next the sash-frame being provided with a slot, 1), for the passage of the end (1 of the catch-bolt E. O is a box-frame cast on the interior of the other wing of said L-frarne,which box-frame is let into a mortise in the side of the windowframe, as seen in Fig. 4.

R is a rack-bar having a part of one of its edges provided with teeth or cogs d. The catchbolt E is secured to or forms a part of said rack-bar, and is consequently movable therewith. Bar B rests against the sides orflanges of the box-frame, and is also guided by means of a projecting plate, f, Fig. 2,which,with the side of the box-frame, forms a recess in which is contained a spiral spring, S.

P is a pinion secured to a stud, g, and provided with any suitable number of cogs, (2, adapted to engage with the cogs of the rackbar. This stud passes out through a hole in the lock-frame, and on its other end is secured a knob or button, H affording a means for rotating the pinion. The periphery of this button is preferably milled orindented,so as to furnish a hold for the hand in turning the same.

A plate or cover, 23, Figs. land 4, is fastened by means of a screw passing into ahole, j,ina lug, k, on the side of the division-platef,thereby aiding to retain the rack-bar and spring in place.

In applying the device to the window a mortise is out into the front side of the frame 122-, and a recess, a, is made in the side of said frame, as seen in Fig. 4, in order to allow free play of the part of the catch-boltthat projects out through the slot 1) in the rack-frame. The lock is then secured to the frame by means of a screw, .r. The edge of the sash-frame is provided with one or a series of recesses, Z, Fig. 4, at suitable intervals apart, for the reception of the projecting end q of the bolt E.

Although not essential, I prefer to secure a slotted plate, T, Fig. 4, over said recesses, in order to have greater durability than if the bolt rested on the wood-work. I also prefer to provide the upper edge of the projecting part of the bolt with a slot, to, Fig. 1, with which the upper edge of the plate engages, and thus avoid liability of the catch slipping or being pushed out from the recess, as it is then necessary to raise the sash a short distance before the bolt can be retracted.

It will be obvious that the spring S retains the projecting part, q within the recess; but when it is desired to elevate or lower the sash it is merely required to rotate the button H in the proper direction, thereby retracting the bolt.

When the lock is applied to the lower sash, it is secured to the 'window frame near the top of the sash. \V hen applied to the upper sash, it is secured near the bottom thereof, as shown in Fig. 3.

I am aware of Letters Patent of Stoddard, No. 169,494, dated November 2, 1875, and No. 134,542, dated January 7, 1883, of Heegler, and do not claim anything shown or described in either of said patents.

Having thus described my invention, I claim as new and desire to secure by Letters Patent- 1. In a sash-lock, the combination of the sliding toothed rack, the angular catch-bolt connected thereto, and the piniomwith means for ICO rotating the same, substantially as and for the and button, all constructed and adapted to 0ppurposedescribed. erate substantially as and for the purpose set 2. In asash-lock, the combination of the slidforth. ing rack, the angular catch-bar connected In testimony whereof Ihave hereunto affixed I 5 5 thereto, the spring, the pinion, and. the knob 1 my signature this 20th day of November, A.

or button, substantially as and for the purpose D. 1884. specified.
