Application tiled March 29, 1883; Renewed March 25, 1385. (No model.)

To @ZZ whom t may concern:

Be it known that I, SAMUEL C. TAYLOR, of Morton, near Bingley, county of York, England, have invented a certain new and useful Improvement in Windows, of which the following is a description sufficiently full, clear, and exact to enable any person skilled in the art or science to which said invention appertains to make and use the same, reference being had to the accompanying drawings, forming a part of this specification, in which- Figurel is a front elevation of a window embodying my improvement; Fig. 2, a vertical transverse section of the same; Fig. 3, a side elevation of the gear and pulley detached; Fig. 4, a sectional isometrieal perspective vi ew representing the pulley and gear in use; and Figs. 5, 6, 7, 8, and 9, views, respectively, of the main pulley, gear, eccentric, clutch-bar, and sleeve. y

Like letters of reference indicate corresponding parts in the different figures of the drawings.

My invention relates more especially to means for raising, lowering, and controlling the sash of the window; and it consists in a novel construction and arrangement of the parts, as hereinafter more fully set forth and claimed, by which a more effective device of this character is produced than is now in ordinary use. l

It is well known that iu large windows or 'those provided with heavy sash it is very difficult to raise and lower the sash by weights and pulleys or the ordinary appliances employed for that purpose. My invention is designed to overcome this difficulty, and to that end I make use of means which will be readily understood by all conversant with such matters from the following explanation, its eX- treme simplicity rendering an elaborate description unnecessary.

In the drawings, A represents the windowframe; B the upper and C the lower sash. A pulley, D, is journaled horizontally on the shaft E in suitable bearings disposed in the upper part of the windowfframe or in the walls of the building near the top of thewindow, and preferably at one side of the same, as shown in Fig. l. One side of the pulley is chainbcred, as shown at Kin Fig. 5, the annular wall of this chamber being corrugated or provided with a series of inwardly-projecting teeth having rounded ends, as seen at m. Mounted on the shaft E, and fitted to work in the chamber,there is a gear, L, provided around its periphery With rounded teeth or corrugations c, and with four laterally-projecting studs, m. A cruciform clutch or locking-bar, M, is also mounted on the shaft, the shaft passing through an elongated slot, t, at its center, anotherA slot, Z, being formed in the lower end of the bar to receive the pin g. Disposed on the shaft E there is also an ee centric or cam, N, provided with the sleeve l?, the eccentric being tted to work in the hole d of thegear L. The sleeve passes through the slot t in the bar M, the eccentric and its sleeve being loose on the shaft. Attached firmly to the outer end of the sleeve P there is a grooved pulley, G, provided with the endless eord H, which extends downward through a hole in the window-casing at a and passes over an Ordinary tension-pulley, J, which may be secured in any suitable position at the side of the window.

In putting the parts shown in Figs. 5, 6, 7, 8, and 9 together the sleeve P is passed from the inside through the slot t in the clutch-bar M, bringing the bar against the cam or eccentric N, the pulley G being then fastened by the key 'o or secured in any suitable manner to the outer end of the sleeve. The gear L is then placed in the chamber K, its studs a: projecting outwardly, and the eccentric N inserted 'in the hole d. The shaft E is then passed through the hole p in the pulley D, hole d in the gear L, and also through the eccentric N and sleeve P, carrying the bar M and pulley G, after which the shaft is journaled in its bearings in the frame-Work Q, as shown in Figs. 2 and 4. The gear L is less in diameter than the chamber K, and provided with one less serration or tooth, so that when the sleeve l? and-eccentric N are revolved by the pulley G and cord H, the eccentric being in the hole d, the teeth a of the gear will be brought into engagement with the teeth m of the chamber, but on one side only of the chamber at a time, as best seen in Fig.

IOL)

4, the gear passing around the interior of the chamber with an epicycloidal movement as the eccentric revolves. If the pulley D is held stationary and the pulley G, sleeve P, and eccentric N revolve, the gear L having one less tooth than the chamber K, and the teeth a m being engaged on `one side of the chamber only, a gain77 will be created as the teeth a slide down `over the teeth m, and the gear thereby caused to revolve in a direction opposite to that in which the pulley G is turning. In order, therefore, to render the pulley D operative, the clutchbar M is used, the arms of the bar fitting into the spaces w between the studs x on the face of the gear L, and its body resting in the spaces b, which are wider than the spaces w and permit the gear to move laterally back and forth as the eccentric revolves. y

In Figs. 1 and 3 the clutch-bar M is repre sented as arranged horizontally, and in Figs. 2, 4, 7, and 8 vertically; and in Figs. 1 and 3 the gear L is also represented as arranged to receive a horizontal bar, the operation of the device being substantially the same whether the clutchbar is arranged horizontally or vertically, although it is deemed preferable to arrange it vertically when con venient to do so. The bar is prevented from revolving with the sleeve on which it hangs by the pin g, which passes through the framework Q in which the pulley D is mounted and through the slot l in the lower end of the bar, and as the pulley G, sleeve P, and eccentric N are turned the gear L will also be prevented from revolving by the studs x, which engage the bar M, thereby causing the pulley D to be revolved in a manner which will be readily obvious without a more explicit description. When the pin g is through the slot l, as shown in Fig. 4, and the sleeveP and eccentric Nare revolved to raise the gear L to its highest point in the chamber K. the bar will be drawn up by the studs x, acting on its arms, which rest in the spaces w, and as the eccentric continues to revolve the gear L will be moved back and forth past the bar, the wide spaces b permitting this movement of the gear asthe arms of the bar slide in the narrow spaces lw. Attached to opposite sides of the pulley D there is a cord, 0, and chain R, which pass downwardly over the friction-supporting rollersf, centrally disposed in the upper part of the window-frame, as best seen in Fig. 1, the cord being attached by a spring-hook, h, to the top rail ofthe upper sash, B, and the chain R by a like hook to the top rail of the lower sash, C. Instead of a cord and chain, however, two cords or chains may be used, if preferred. Above the sash B there is a door or ap, F, hinged at its upper edge to the top of the win dow-casing and opening inwardly. This door may be let down,as shown in Figs. 1 and 2, and when in a vertical position its lower edge fits into a shoulder or rabbet in the top rail of the upper sash, B, to make a tight joint of these parts. Asupplemental or auxiliary sill,

T, is employed for the window, this sill being inserted for use under the lower sash, as seen in Fig. 1. The sash C is provided with two flap-hinges, r, the upper halt of the hinges being attached to the lower rail of the sash, and lower half left to hang free. Two vertical sockets, j, corresponding with the lower portions ofthe hinges r, are formed in the sill T, and there are also two similar sockets, e, formed in the main sill U. A portion of the band Y which secures the sash C in its ways is cut out, and fitted into the cavity thus formed on either side of the window there is a bar, I, pivoted at 25, near its upper. end, and adapted to swing outwardly, thelower sash being held in its ways by a laterally-projecting stud, q, at either end of its top rail, and by corresponding studs, y, at either end of its lower rail,which work in the groove 27. The length of the sashes, B and C are such that when the door F is turned down or closed and the auxiliary sill T inserted the window will be shut, as shown in Fig. 1. When the sash C stands on the sill T, with the lower ends of its hinges r in the sockets j, the studs q will be above the pivots 25 of the bars I, and it will be securely held in a vertical position by the band Y, but when the auxiliary sill is removed and the sash permitted to drop onto the sill U the studs g will pass below the pivots of the bars I, and the sash may then be tilted or tipped forward into the room, as shown in Fig. 2, the lower portions of the hinges 1' standing in the sockets e and being secured by the pin 14. The bands Y are also cut away at their lower ends,as seen at. z,to admit the sill T, and when said sill is removed the lower part of the sash C may be drawn out, the studs y passing through the openings z. The lower portions of the hinges r are provided with holes, and pins 14 are used to secure them in the sockets j e, thereby fastening the sash and preventing it from being raised from the outside of the room or building. The sashBis also provided with downwardly-projecting flanges 20, which enter the sockets 22 in the sill U, and may be secured by the pins 14, when desired. The door F acts as a ventilator for the room, connecting with ilues (not shown) in the Walls of the building or opening into the usual space between the walls when it is raised.

In the use of my improvement it will be obvious that the sash may be readily raised or lowered by means of the cord H, and that as the cord O and chain R lpass around the pulley D in opposite directions the sashes B C will counter-balance each other, one being raised when the other is lowered. I do not, however, confine myself to this arrangement of the cord and chain on the pulley D, as they may be operated to lift the sashes separately, or one at a time, and may be passed around the pulley in tbe same direction, if desired. By removing the auxiliary sill T the room may be readily ventilated either below the lower sash, between the sashes, above the upper sash, or by tilting the window, as shown lin Fig. 2. When the cord and chain are not in use, they may be drawn up into the casing of the Window, or swung to one side and attached to any convenient support.

It will be obvious that the heaviest sash may be readily raised,lowered,and controlled, as desired, by means of the mechanism described, which, although more especially designed for sashes of this character, is also well adapted for medium and light weight sashes.

Instead of attaching the cord and chain to the sash at the center, as described, two cords and two chains may be used for each sash, and so arranged as to be attached to the sides of the sash, if desired.

Having thus explained my invention, what I claim is- 1. In a device for raising,lowering, and controlling the sash ofa window,thepulley D,hav ing the chamber K,provided with the teeth m,
