Jean in. Jones, or tonsvrnmjrnaas.

To all whom inmay-concern Be it known that 1, JOHN T. Jones, a citizen of the- UnitedI States, resident of Longvie'w in the county of Gregg and State of Texas, have made a certain new and .useful Invention in Sash-Balances; and I declare the following to be a full, clear, and exact description of the same, such aswill enableothers skilled in the art to which it appertains to make and use the invention, reference being had to the accompanying drawings, and to letters or figures of reference marked thereon, which form a part of this specification.

Figure ,1 is ,a front view of the invention as applied, the window casing being shown in section on the line 1'1, Fig. 2. Fig. 2 is a side view of the invention as applied. Fig. 3 is a detail face view of the sash weight partly broken away. Fig' 4 is a detail side view of the sash weight. Fig. 5 is a detail perspective view of the pulley and its frame.

The object of the invention is to provide improved means for balancing the sashes of windows, and it consists inthe novel construction' and combinations of parts, as hereinafter set forth.

' In the accompanying drawings, illustrating the invention, the numeral 2 indicates the casement framing of a window, and 3, window sashes. 4 are the lateral boxes for the reception of the weights which are designed to counterbalance-the sashes.

The numeral 5 designates the improved sash weight, which is of elongated form and of rectangular oblong shape in cross section. The lower portion of the weight consists of a series of detachable lobes 6, which are connected by narrow neck portions 7, formed by circumscribing notches 8. These lobes are about an inch or two in vertical length, the entire weight being about fourteen or fifteen inches, or of such dimensions as may be required. The middle or body portion of the weight is solid, and the upper portion is provided with arecess 9, open at each side and at its upper end. This recess is designed to receive a pulley and its frame,

., Y and is located between two parallel walls 12,

12, which are separated sufficiently to receive between them the frame of a pulley, and are provided with bearings or ln s 14 at'their upper portions. Atone side tiese lugs project inward or toward each other, the distance between them being sufiicient for the passage of a-sash rope 10.

Specification of Letters Patent. I

' Application filed February 14, 1914. Serial No. 818,814.

SASH-BALANCE.

Patented Sept. a, 19314.

The pulley frame- 15 may be used; at the 'upper end of the weight box, for the upper pulley of the sash rope, as well as: in the weight recess. But this frame is not de signed tobelonger than the sash weighti is lde, and preferably consists of a sheet from a slotted bottom 18, a pulley 19 being tion, the ends of which are curved inward and toward each other, to provide guidin passages for the rope 10. The frame 15 an its pulley is designed to be readily inserted through a lateral opening into the recess of pulley upward between the walls of the recess 1n its upper portion, its flanges 17 engaging the bearings 14. The pulley and its frame can be put in place with the rope in engagement, as the rope can be readily passed between the lug bearings of the recesswhen the frame is inserted. The weight can, therefore, be readily attached or detached from the pulley and frame and connected rope, and its exchange or modification is readily effected when necessary. If the weight is too heavy for the sash or sashes to which it is being applied, one or more of the lobes should be broken off, in order to The weights are designed to.be cast in a foundry, the upper end portion being cored out to form the recess for the pulley. In use, the weights are applied as follows. One end of the rope or cord is fastened to one of the sashes, and the rope is thencarried up over a pulley 23 in the window frame box of this side, and down through the weight engaging the weight pulley. Thence the rope extends up, over the other window frame pulley 24, located alongside the pulley 28, and down to the other sash, to which it is secured. Another weight is used in the window box at the other side of the window frame, and is connected to the other sides of it is designed to balance both sashes by means of a single pair of weights. The

to the sashes and. pulleys, and the weights, being attachable and detachable, can be hung on at'any time, by inserting the weight pulleys and their frames into the recesses of the weights. These weights are usually made fifteen inches long, by one and threequarter inches, by three and three quarter metal body having and fiangesl-T projecting pivoted between the walls of the body porreduce this weight according to requirement.

ropes can be cut to length and connectedthe sash weight, and is adjusted with the he sashes in a similar manner. In this way 7 inches. Double Windows may be made With a middle frame box measuring four inches by' four inches. The movement of the Weight is shortened When compared to that re uired Where the rope is fastened to the weight. And because of the pulley engagement and the use of a single Weight in the Window frame box, the Wear on the rope is inapp reciable, and the movement of the weight is smooth and comparatively noiseless. 7

I claim 1 In a sash balance, the combination With a Weight having at its upper portion a recess having a lateral opening, and stop means at the upper portion of said recess, of a laterally insertible and removable pulley frame designed to be first passed into said recess through said lateral opening and then raised in said recess, said pulley frame hav 7 ing in raised position engagement with said stop means to prevent movement of said frame out of said recess and to'limit the upward movement of'said frame in said recess.

In testimony whereof I afiix my signature in presence of two Witnesses.
