No. 210,904. Patented Dec. 17, I878= INVENTDR:

UNITED STATES PAT CHRISTIAN BISSMANN, OF NEYV YORK, N.'Y.
IMPROVEMENT IN SASH-ALANCES.
Specification forming part of Letters Patent No. 210,904, dated December 17', 1878; application iiled July 1, 1878.
To all whom it may concern I Be it known that I, CHRISTIAN BIssirAnN, of the city, county, and State of New York, have invented a new and Improved Sash Balance, of which the following is a specification:
In the accompanying drawing, Figure 1 represents a sectional front elevation of my improved sash-balance, and Fig. 2 shows a horizontal section of the window-casing with one balance in horizontal section on line y y, Fig. 1, and the other balance in top View.
Similar letters of reference indicate corresponding parts.
The object of this invention is to furnish, in place of the common boxes, with cords, pulleys, and weights, for window-sashes, an improved spring-balance that takes up less space, and by which the raising and lowering of the sash are accomplished in easyand noiseless manner and the sash retained in any position without shaking or rattlih g.
The invention will first be described in connection with the drawing, and then pointed out in the claim.
Referring to the drawings, A represents a cylindrical casing, that turns on a fixed shaft in supporting-arms B. The casing A is connected with the fixed shaft by a strong spiral bainl-spring, 0, that is attached at the inner end to the shaft and at the outer end to the casing A. It is also provided with a circumferential ring, D, of soft rubber or other elastic material, that projects through a slot of the window-casing and bears on the grooved end of the sash. The balance is support-ed in a cavity of the window-casing at a level with the meeting-rails of the sash, the supportingarins being secured to a slotted faceplate, E, that is screwed flush to the window-casin The elastic ring is of such thickness as to bind sufficiently on the sash, so that the casin g A is revolved by the friction therewith when the sash is raised or lowered.
The tension of the spring 0 is regulated in proportion to the size and weight of the sash by means of a pawl, 13, that engages exterior ratchet-teeth F of the casin The pawl l? and ratchet F serve to lock the spring-casing until the sash is placed in position. The pawl .is then disengaged by means of a releasing slide-piece, F that is guided along the rear of the face-plate and pushed down by means of a stud or fin ger-rest, a, projecting through a slot, at, of the face-plate. A rear projection or stud, b, of the slide-piece engages a forwardextending arm of pawl F, and withdraws the same from the teeth of the ratchet, so that the spring-balance is ready to act on the sash. The lifting of the sash is facilitated by the action of the spring-balances on the same, while the lowering of the sash rewinds the springs of the balances to the former degree of tension.
As a spring-balance is arranged at each of the upper corners of the saslnvthe joint action of the balances accelerates the raising of the sash and supports it at any desired point in the same manner as the balance weights. When the tension of the spring is not sufficient for the sash, it may readily be readjusted by removing the sash and-sash-balance and turning the spring-easing until the required degree of tension is obtained. The balance and sash are then replaced and the pawl disengaged from the ratchet of the casing by the slide-piece.
In case the rubber contact-rin g wears out, either a new one maybe placed around the casing, or the supporting arms or bearings may be made adjustable by a set-screw or in other manner from the outside, so that the rubber ring is brought closer to the sash, and thereby the former degree of efficacy reestablished. The sash-balance is secured to the face-plate with all its parts, and the same readily placed in position or removed from the window-casin The upper corner of the-sash has a metal-lined projection or heel, that bears on the sash when in its lowermost position, while the lower corner is guided by an antifrietion roller along the casin The springbalances bind on the grooved end of the sash and hold it firmly in position, so as to prevent rattling and secure the easy and noiseless opening and closing of the window.
I am aware that it is not new in sash-balances to balance the sash by a coiled spring in a revolving case provided with an external of 1 theface plate, in combination with the elastic friction-surf'ace, or to use a pawl and pawl F, having a forwardly-extending arm, ratchet but as and for the purpose set forth.
What I do claim as new and of my inveu- CHRISTIAN BISSMANN.
