SASH-BALANCE.

SPECIFICATION forming part of Letters Patent No. 416,207, dated December 3, 1889.

Application filed September 15 3, 1889. Serial No. 324,312. (No model.))

To all whom it may concern:

Be it known that I, JACOB BAsTIAN, of Dansville, in the county of Livingston and State of New York, have invented certain new and useful Improvements in Sash-Holders; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, and to the letters of reference marked thereon.

My present invention relates particularly to that class of sash-holders adapted to prevent the sudden descent of the sash and to hold the same at any desired point, but which will permit it to be moved freely in an upward direction, the object of the invention being to produce a superior and cheap device for accomplishing the desired end which shall be noiseless and composed of few and simple parts.

The invention therefore consists in certain novel details of construction and combinations and arrangements of parts, to be hereinafter described, and pointed out particularly in the claims at the end of this specification.

In the accompanying drawings, Figure 1 is a perspective View of a holder constructed in accordance with my invention, a portion --of the frame being broken away and the sash and easing shown in dotted lines. Fig. 2 is a Vertical section. Fig. 3 is a side elevation with the side of the frame removed. Fig. 4 is a section at right angles to Fig. 2.

Similar letters of reference in the several figures indicate the same parts.

The frame A, in which the working parts of my invention are mounted, may be of any desired construction, although preferably constructed, as shown, with the back open and with an opening in the front plate for the passage of the supporting'strap, and through which the brake may be tightened, as will hereinafter appear. The sides of the frame are of course suitably braced and bound together with rivets and pillars or bolts, and journaled in said sides is the shaft or axle B, to which is rigidly secured the friction-drum O and ratchet-Wheel D. The drum B is preferably of wood, and is securely fastened, by rivets or otherwise, to a plate or disk E, formed integral with the ratchet-wheel and axle. At one side of and partially surrounding the ratchet-Wheel and drum is journaled the winding drum, consisting of the grooved wheel F, adapted for the reception of the supporting-tape G, and the annular extension H, surrounding the shaft, and to which is attached the inner end of the retracting-spring I, the opposite end of said spring being attached to the bolt 1' on the frame. IVithin the grooved wheel, and in position to engage the ratchet-wheel, are located four spring-pressed pins K, which constitute pawls and serve to lock the drum and wheel together when rotated in one direction, but permit of the free rotation of the wheel in the opposite direction. The spring I is so arranged as that when wound it will tend to move the Wheel in the direction of its free rotation. With this arrangement it will be seen that when the supporting-tape G, which is wound in a direction opposite to that of the spring, is drawn out the friction drum and wheel will be locked rigidly and rotate together; but when said tape is released the wheel moves freely in the opposite direction. In order, now, to retard the outward movement or unwinding of the supporting-tape, a friction band or brake M is passed around the friction-drum and one end made fast to the frame A, said band or brake being essentially the same as that described in my patent, No. 375,252, dated December 28, 1887, save that, for the sake of convenience, the shorter arm is toward the rear, and the head of the screw for tightening the band is in convenient position for manipulation through the opening in the front of the frame, thus enabling all wear on the band and drum to be readily taken up and the devices to be easily and quickly adjusted for the support of light or heavy sashes.

As will be readily understood from the foregoing, the frame and operative parts of the device are mounted in the window-casing, at the top of the sash, and the end of the supporting-tape fastened to the bottom of the sash. Thus when the sash is moved upward the tape is slackened and the spring immediately rewinds the same; but when the sash is moved downward it has to overcome the resistance of the friction-brake and spring, the former being adjusted to hold the sash at any desired point.

The supporting-tape is in tl e device herein shown formed of metallic ribbon of any suit able kind, although it is obvious that any preferred form of tape, cord, or chain may be employed.

WVhile it is obvious that a spring of such strength as to in a measure counterbalance the weight of the sash and tend to raise the same, and thus overcome the dead weight of the sash to a greater or less extent, may be employed, I prefer to employ a comparatively light spring, of sufticient strength only to return the tape to position on its wheel, as the spring may thus be made much longer and the device adapted for application to tall sashes, which is not practicable where the spring is relied upon to hold the sash at a given point, owing to the great variation in the strength of the spring, unless the same be extremely large and strong. 5

Having thusdescribed my invention, what I claim as new is- 1. In a sash-holder, the combination, with the frame, the axle journaled therein, the friction-drum and supporting tape-wheel mounted on said axle, and the spring connected to said wheel, of the clutch-connection between the drum and wheel, and the frictionbrake surrounding the drum, substantially as described. I

2. In a sash-holder, the combination, with the frame having the opening in the front, the axle jou rnaled in said frame, the friction-drum mounted on said axle, the supporting tapewheel also mounted on said axle, the spring connected to said wheel, and the pawl-andratchet connection between the wheel and drum, of the friction-brake surrounding the drum, connected at one end to the frame, and the screw for tightening said brake projecting through the opening in the front; of the frame, substantially as described. a

3. In a sash-holder, the combination, with the frame, the axle journaledtherein, the friction-drum mounted on the axle, and the friction-brake surrounding said drum, of the supporting tape-wheel mounted on the axle, with the annular projection at one side surrounding the axle, the spring connected at one end to said projection and at the opposite end to the frame, and the pawl-andratchet connection between said drum and wheel, substantially as described.

JACOB BAS IAN.
