IMPROVEMENT IN SASH-BALANCEVS.

u Specification forming part of Letters Patent No. 154,597, dated September 1, 1874;. application tiled June 20, 1874. v

To all whom it may concern:

Be it known that I, LEwrs .FEGLEL of Port Carbon, in the county of Schuylkill and State of Pennsylvania, have invented a new and valuable Improvement in Sash-Balances and I do hereby declare that the following is afull, clear, and exact description of the construction and operation of the same, reference being had to the annexed drawings making a part of this specification, and to the letters and figures of reference marked thereon.

Figure l of the drawing is a representation of a front view of my sash-balance, and Fig. 2 is a sectional view. Figs. 3 and 4 are det-ail views.

This invention has relation to sash-balances, wherein are used saslrcords, passing over pulleys in the window-frame, and on the sashes to which the said cords are attached, whereby, when the lower sash is raised, the upper sash will be lowered, and vice versa. The novelty consists in a windlass for windin g up the sash-cord, which windlass is applied in its bearings so as to have endwise play, whereby a tooth, upon a crank-arm rigidly secured to the end of the windlass-shaft, may be engaged with or disengaged from a toothed rack upon a face-plate of the windlass-case, thereby admitting of the sashes being balanced, or of either of them being lowered or raised independently of the other. y

In the annexed drawings, A designates a window frame., into which are set in the usual wellknown manner an upper sash, B', and a lower sash, B. a a designate groovcd pulleys, which are rigidly secured at either end of the top rail of the lower sash, B, and b b designate grooved pulleywheels, applied in pairs on each side of the window-frame and at the top part thereof. O designates a semi-cylindrical hollow cover for a windlass, consisting of a rounded top, d', and two closing portions, c c', for the ends thereof, and which also afford bearings for the shaft `of the said windlass. ff are flanges constructed upon the edges of the cover C, whereby it is conveniently and rigidly secured to the top rail of the lower sash B. The front end e of the cover C is circular in form, and it is provided with a circular toothed rack, g, for a purpose hereinafter to be explained. D rcpresents a winding-drum, having flanges h constructed upon both ends thereof, which will prevent the sash-cord, when being wound around its periphery, from becoming engaged with the actuating shaft or its attachments. The said drum is applied within the Vcover C, and has bearings for its shaft t' in tne ends e e thereof. E designates a crank-arm, having a handle at right angles thereto, by means of which it is actuated, which crank-arm is rigidly secured to the shaft tin any suitable manner, and is provided with atooth, j, upon its under surface, to engage with the toothed rack g, for a purpose herein after to be explained. Through the periphery of the winding-drum D a perforation, d', is made, through which is passed a sash-cord, f', of suitable length and strength, whicn passes thence over the pulleys a a', and then over the pulleys b b', and it is then rigidly attached to the upper ends of the top rail of the upper sash B. If the slack of this cord be now taken up vby working the windlass, and the tooth j of the crank-arm E be engaged with the tooth-rack g, by pushing the windlass inward, so as to keep the said cord properly tense, the sashes B Bl will balance one another, so that if the one be raised the other will be lowered. The two sashes being in the position shown in Fig. 1, the lower sash may be raised by operating the winding device, irst pulling the winding-crank outward to release the tooth from the rack, and it may be held in any desired position by bringing the tooth j and rack g into engagement, as above described. The two sashes being in the position as above indicated, the upper sash may be lowered by disengaging'the tooth j from the rack g, and secured at any desired elevation by re-engaging the tooth and the rack.

I' have described the windlass cover and frame as being constructed of separate pieces, which were subsequently united, butImay, if I so prefer, cause them to be cast in one piece.

F designates a hollow rectangular bolt-holder, which is cast upon the upper surface of the windlass-cover C, and has in its rear end, and on its upper surface, a longitudinal slot, k. Within this bolt-holder, in the hollow portion-thereof, is applied a bolt, Gr, around the shank of which is coiled a spring, Z, and upon which is rigidly secured a stud, m, by means of which the said bolt may be retracted when desired. The outer end ofthe bolt G is adapted to be engaged with a catch, n, which is rigidl;r secured to a suitable portion ofthe upper sash, and which, when thus engaged, will prevent either sash from being readily lowered or raised from the outside.

What I claim as new, and desire to secure by Letters Patent, isy l'. In a device for balancing WindoW-sashes, the combination, with the sashes B B ,pulleys a a b b', of a sash-Windlass, perforated for the passage of the cord f and having endWise play, for the purposes set forth, substantially as specified. Y

2. The combination, with the sash-balancing` endwise-moving` Windlass-shaf't i, of the rack g and toothed crank E, substantially as speciied.

3. The Windlasscase for balancing Windowsashes, having a lratchet-face and journalseats, in combination With an endwise-lnoving Windlass-shaft, and a pawl-crank rigidly connected thereto, substantiallT as specified.

In testimony that I claim the above I have hereunto subscribed my name in the presence of two witnesses.

lLEI/VIS FEGLEY.
