SASH -BALANCE.

SPECIFICATION forming part of Letters Patent No. 251,943, dated January 3, 1882.

Application filed May 20, 1881. (No model.)

To all whom it may concern:

Be it known that I, J OHN ALBERT Qmc r, of Palestine, in the county of Anderson and State of Texas, have invented a new and useful Improvement in Sash-Balances, of which the following is a full, clear, and exact description, reference being had to the drawings hereto annexed.

The object of my invention is to furnish a" 1 sashes in a locked position; Fig. 2, a partial view of the same, showing the adjustment of the cords for letting down the top sash without hoisting the bottom one; and Fig. 3, detail views.

Referring to the drawings, A represents a windowframe, having two pulleys, a a, secured to the under side of its top portion just in front of the top sash, b. The pulleys are thus 'exposed to view and may be easily reached in case repairs are needed. Two cords, a a, are secured to the front portion of the sash on opposite sides, a little below the top thereof, and passed over the said pulleys, respectively, from which they are conducted downward under pulleys c 0 on top of the bottom sash, b, then along the top of said bottom sash, passing each other, to spring-hooks d, to which they are secured by eyes attached to the ends thereof. As arranged, each cord extends along the top ofthe bottom sash and up one side of the frame. The pulleys a a and c c are arranged with their planes at right angles to each other respectively, but may, if desired, be arranged otherwise. The said hooks d are provided with spiral springs d, which are secured at one end This attachment is provided with a horizontal,

slot, by which it is secured adjust-ably to the bracket of either of the pulleys c o by means of a screw, which also serves as the pivot of the pulley. I

When the cords are of proper length the operation of the spring will tend to press the top sash againstthe upper part ofthe frame, whereby a close adjustment will be formed to keep out wind and dust. trifle too short or too long the action of the springs will be brought into requisition by adjusting the attachments e horizontally by means of the slots and screws. By unhookin g the cords the top sash may be lowered until the ends of the cords are drawn to the pulleys c 0, respectively. To accommodate the cords, one attachment, 6, is secured on the outside and one on the inside of pulleys c c, respectively.

The sashes, whenclosed, maybe held in po-- sition by a horizontal lever, i, pivoted tothe top of the bottom sash and adapted to oscillate under a flange secured to the top sash.

"Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-- In a sash-balance, the combination, with pulleys a a and cords a a, of the pulleys c 0, which are arranged on the top of the lower sash and provided with horizontally-adj ustable attachments 6, having hooks d and springs 01, substantially as shown and described, and for the purpose set forth.

JOHN ALBERT QUICK.
