SASH I'A'STENEB,

w. n m e UNITED STATES I PATENT OFFICE.

ROBERT MALOOLMSON 'HUTOHINSON, OF BOSTON, MASSACHUSETTS.

- SASH-I-LASTENER.

SPECIFICATION forming part of Letters Patent No. 352,189. dated November 9, 1886.

Application filed September 30, 1886. Serial No. 214,966. (No inodelJ To all whom it may concern.-

Be it known that I, ROBERT MALOOLMSON HUTOHINSON, of Boston, in the county of Suffolk, of the Commonwealth of Massachusetts, have invented a new and useful Improvement in Window-Sash Fastenings; and I do hereby declare the same to be described in the follow- .ingspecification and represented in the accompanying drawings, of which Figure l is a front elevation of a railwaycar window frame and sash with my invention applied thereto. Fig- 2 is a horizontal section taken through the spring-latch and the parts adjacent. Fig. 3 is a transverse section of the window-frame, showing the grooved and notched bar and its arrangement therein. Fig. 4 is a front elevation; Fig. 5 a front end view, and Fig. 6 a top view, of the spring-latch and its carrier and operative spring. Fig. 7 is a front view of the bar provided with the groove and the notches opening out thereof, as explained.

The nature of my invention'is defined in the claim hereinafter presented.

In carrying out my improvement I insert and fix in the rear part of one of the vertical grooves g of the window-frame F, in which the sash A is placed and is movable vertically, a metallic bar, B, which has lengthwise in it a groove, a, and a series of angular notches,

b b b, the latter being arranged at equal distances apart and opening out of the groove,

I and formed as represented.

Within the sash I insert the spring-latch O and its carrier D, so that such latch at its front end may extend into one of the said notches. This latch is a lever arranged in and fulcrumed to the carrier D, which is provided with a spring, E, to force the latch into the notch. The carrier at its front has a slot, 0,

The latch at its rear part is bent at about a right angle, and in front of the posterior end ofthe latch is a small ball or button, d,which is held in place by a circular cap, e, screwed or fastened to the sash, the whole being so as to enable a person, by pressing his finger on the ball or button, to force it inward and move the latch out of engagement with one of the notches, or from it into the groove.

On raising the sash the lat-ch will slip from one into the other of the notches in succession, so as to hold the sash at any desired altitude within the range of its motion. On pressing the ball or button in and holding the latch out of engagement with the notches the sash may be depressed, the latch at the time moving in the groove. i

The above-describedsash-fastening is speoially applicable to and useful for railway-car windows, it being very simple and efficient in its operation, the manner of operating it being readily suggestive to a passenger. With it a sash cannot easily accidentally fall on the head or arm of a person, to the injury thereof.

I claim- The combination of the bar B, fixed in the windowframe F, and provided with the groove a, and the series of notches b, arranged, as represented, with the spring-latch O-and'its carrier D, and with the ball or button at and its confining-cap 6, arranged with and applied to the sash A, substantially as set forth.
