T @ZZ whom t may concern:

Beit known that I, FRED W. HIRoNiMUs, a citizen of the United States, residing at Corydon, in the county of Henderson and State of Kentucky, have invented a new and useful Sash Balance and Lock, of which the following is a specification.

The invention relates to improvements in sash balances and locks. j

[o The object of the present invention is to improve the construction of spring sash-balances and to provide a simple and efficient lock adapted to fasten a window either open 0r closed or at any-adjustment and to pre- I5 vent the same from being moved upward or downward by exterior pressure.

The invention consists in the construction and novel combination and arrangement of parts, as hereinafter fully described, illuszo trated inthe drawings, and pointed out in the claim hereto appended. i L

In the drawings, Figure l is an elevation of a portion of a window provided with a sash balance and lock constructed in accordance z 5 with this invention. Fig. 2 is a vertical sectional view on line sa :c of Fig. 1. Fig. 3 is a similar view on line y y of Fig. 2. Fig. 4. is a detail perspective view of the locking device. Fig. 5 is a similar view of a portion of 3o the casing, illustrating the construction of the stop for engaging the handle of the locking device. i

Like numerals of reference designate corresponding parts in the several Iigures of the drawings.

l designates a casing mounted in a recess of a window-sash 2 and having a windingshaft 3 mounted in it and disposed horizontally, and upon the winding-shaft is mounted a spring-actuated gear-wheel 4.., The gearwheel, which is connected with the windingshaft by a clutch of the ordinary construction, is connected with one end of a barrelspring 5, which has its other en d secured to the casing and which is designed to take the place of a sash-weight in balancing the sash. `The spring-actuated gear-wheel meshes with a pinion 6 of a shaft 7, which also carries a cog-wheel 8, andthe latter engages a rack- 5o bar 9 of the window-frame 10, and the raising and lowering of the sash winds and unwinds the spring, as will be readily apparent. VThe clutch, which connects the spring-actuated gear-wheel tothe winding-shaft, operates in the ordinary manner and enables the spring to be wound up to the proper tension for balancing the sash, and after the spring has been adjusted to the proper tension it does not require any further attention.

The sash, which is designed to be provided 6o at each side with a sash-balance, is locked at anydesired adjustment by a locking device 11, consisting of a crank-loop disposed transversely of the casing and j ournaled at its ends thereon. The crank-loop is adapted to engage the cog-wheel, and its engaging portion is substantially triangular in cross-section to fit the spaces between the teeth of the wheel, which is held against rotation in either direction. The outer end of the crank-shaft is eX- 7o tended through the casing and has a handle 12 secured to it and arranged on the faceplate of the casing, which is provided with a p protuberance 13, forming a stop to lock the handle against upward movement and thereby retainthe locking device in engagement with the cog-wheel. The protuberance forms a shoulder at one side and a beveled face at the other side, and it effectually prevents the locking device from being thrown out of en- 8o gagement with the cog-wheel by shaking or j olting the sash.

It will be vseen that the sash balance and lock is adapted to be readily applied to any ordinary window, that it will' take the place 85 of sash-weights and sash-fasteners, and that the locking device is adapted to securely liasten asash either closed or at any desired adjustment, and that it cannot be'thrown out of engagement with the cog-wheel by jarring 9@- or `jolting the windowsash- In a device of the class described, the com` bination with a window-frame having a racky bar, and a sash, of a spring-actuated cogwheel mounted on the sash and meshing with the rack-bar, a crank-loop j ournaled in suitable bearings and arranged to swing into and out of engagement with the .teeth of the cogwheel and having one end or journal extended roo through the Window-sash, a easing or plate A mounted on the sash and provided with a protuberanee 13 struck up from the metal of the easing or plate and having a beveled face at one side and a shoulder at the other, and a f handle arranged on the exterior of the plate or easing and secured t0 the extended end or journal of the crank-loop, said handle being arranged to swing into and out of engage-
