SPECIFICATION forming part of Letters Patent No. 644,949, dated March 6, 1900. Application filed November 1, 1899. Serial No. 735,503. (No model.)

To all whom it may concern.-

Be it known that I, THOMAS MANLY SPINKS, a citizen of the United States, residing at Shubuta, in the countyof Clarke and State of Mississippi, have invented a new and Improved Sash-Balance, of which the following is a full, clear, and exact description.

One object of theinvention is to so construct window-sashes that sash-weights need not be employed and to provide a construction whereby fon r sashes are used in a frame, the sashes being balanced in pairs, and in which one pair of sashes is arranged to balance another pair.

pair of sashes may be operated independently or bothpairs si in ultaneously.

The invention consists in the novel construction and combination of the several parts, as will be hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming apart of this specification, in which similar characters of reference indicate corresponding parts in both figures.

Figure 1 is a front elevation of windowsashes and a portion of a window-frame in which the sashes are mounted, parts of the frame being broken away; and Fig. 2 is a longitudinal section through the window-frame and through the sashes at a point near one of their ends.

The window-frame A is of the ordinary type, except that the said frame is provided with a double set of sash-grooves, since four sashes are used in closing the opening of the windowframe. These sashes are arranged in pairsnamely, an upper pair ofsashes B and B and a lower pair of sashes C and 0'. Each pair of sashes is of the same construction as the ordinary sashes of a window-frame-that is to say, the upper member of the lower member of the upper sash are meeting-rails, but the lower member of the lower sash. of the upper pair constitutes a meetingrail 10, as does also the upper rail or member 11 (if the upper sash of the lower pair, as shown in ig. 2.

A cord 12 is secured to the upper sash of the upper pair at each end, extend downward and are attached 'to the upper rail of the lower sash of the upper pair,

the lower sash and a d as shown in Fig. 2, and the cord 12 is passed over a pulley 13, located in a chamber 14 in the upper portion of the window-frame, above the upper sash when the sashes are closed.

Cords 15 are located at each side of the win-- dow-frame pair balances the other, and one pair of sashes serves to balance the other pair, so that by movlng the cords 12 thesashes of the u per pair may be adjusted independent of t e sashes of the lower pair, and the sashes of the lower pair dependent of those of the upper palr by ma- 17. Thus it will be observed that the two sashes of the upper pair may be brought one immediately back of the occupy a position between the top of the window-frame and the upper portion of the lower pair of sashes, and the lower pair of sashes may be correspondingly arranged, or all of the sashes may be placed one at the rear of the other at any point in the length of the window-frame, thus enabling more complete ventilation to be obtained than when sashes are When the window is open to its fullest extent, ihe sash only occupies one-fourth of the opening.

Having thus described my invention, I claim as new and-desire to secure by Letters Patent- 1. A window-frame, sashes mounted in the window-frame, the sashes being arranged in pairs, each sash of a pair balancing the other and the sashes of one pairbalancing the sashes other and made to.

may be adjusted inof the mating pair, and means, substantially as described, for independently moving the sashes of either pair; or simultaneously operating both pairs of sashes,

2. The combination, with a window-frame, of two pairs of sashes, the sashes of each pair being mounted to slide in the said frame, one sash of a pair balanein g the other andone pair of sashes balancing the mating pair, cords connecting the upper rails of the sashes of each pair, rollers over which the said cords pass, rollers journaled in the frame, and conneeting-eords passed over the guide-rollers and secured to the first-mentioned rollers, whereby each pairof sashes may be indepem ently operated or both pairs of sashes simultaneously operated, as set fortln In testimony whereof I have signed my 1 name to this specification in the presence of two subscribing witnesses.
