JACOB BARROW', OF WINDFALL, INDIANA.

SPECIFICATION forming part of Letters atent No. 706,008, dated August 5, 1902. Application filed July 271 1901. Serial No. 69,969. (No model.)

T0 all whom it may concern:

Be it known that I, JACOB BAEROW, a citizen of the United States, residing at Windfall, in the county of Tipton and State of Indiana, have invented a new and useful Sash-Balance, of which the following is a specification.

My invention is an improvement in sash balances and fasteners, and has for its object to provide an arrangement whereby the counterbalancing-weights and ropes may be dispensed with. To accomplish this object, I arrange a series of pulleys within the windowframe and upon the sashes, over and around which is passed a cord or rope that is securely held at one end to the upper sash and adjustably connected near its opposite end to the lower sash and by which the two sashes connterbalance each other and may be locked to any position to which they are adjusted.

A further object of my invention .is to provide a lock to secure the lower end of the rope which shall be of simple construction and easy Ofoperation;l and with these objects in view my invention consists in the peculiar construction and novel combination of parts, as will be hereinafter fully described in the specilcation and pointed out in the claim, reference being had to the accompanying drawings, in Which- Figure lis a perspective view of a sashframe embodying my improvements, parts of the frame being broken away. Fig. 2 is a face view of the same. Fig. 3 is an enlarged section of the upper end of the frame, and Fig. 4 is a detail view illustrating the lock.

In adapting my invention to windows it only becomes necessary to arrange a recess in the upper portion of the frame directly above the sash; otherwise the frames are' exactly as those now used when the counterbalanceweights are omitted.

sash C is fastened a cord or rope E, which is then extended up and over the pulley B, thence down around the pulley D', thence across the top of the sash and around pulley D2, when it is extended up over a pulley B', thence down around the pulley C', secured to the upper sash C, then up and over pulley B2, when it is iinally carried down to the lower sash, where it is fastened to the catch or lock F. This lock is of a peculiar yet simple construction, consisting of a U-shaped bracket F', in which is eccentrically pivoted a block F2, having an aperture f arranged therein that is normally arranged on an angle to the vertical line of the sash. A cord Gis connected to the blocks to facilitate the operation thereof, as will appear later on.

The operation of adjusting the upper and lower sash together or of either sashindependent of the other is as follows: Should it be desired to adjust the upper sash=say for ventilationntlie operating-cord G is given an outward pull, turning the block on its axis until the aperture attains practically a vertical position, which releases the cord, when the window may be adjusted as desired by reason of the cord slipping through the block, the sash dropping of its own weight until the cord G is released, which permits the lock to readj ust itself and firmly hold the cord, locking the sash in place. the lower sash it is only necessary to pull downwardly upon the cord E, which draws the sash up to any height desired, and if both the upper and lower sash are to be adjusted it will not be necessary to disturb the lock F; but by raising the lower sash the upper one will drop of its own weight and take up the slack in the rope.

The operationr of closing the sashes will be readily understood.

By reference to Fig. 4 of thedrawings the operation of the lock will be readil understood. It will be seen that the blocly has its axial bolt arranged near the upper edge theres of and the aperture arrangedbetween the axis and the sash. The cord is passed through the aperture from the top and out through the bottom, and as the pull upon the cord is in an upward direction the tendency will be to revolve the block, as indicated by arrow l, which brings `the cord protruding through Now to raise` the lower end of the block against the bracket, locking it firmly, as will be readily understood.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

In a lock for sashes operated in the manner described, the combination of a bracket, a

circular block eccentrically journaled there- -Io in, the said block having an aperture which is normally arranged at an angle to the Vertical line of the sashes, and a rope engaging the sashes and lock whereby through the Weight of the upper sash the cord is held in the lock, and a cord for operating the lock, 15

substantially as shown and described.

JACOB BARROW.
