sAsH-BALANCE.

SPECIFICATION forming part of Letters Patent No. 317,262I dated May 5, 1885.

Application led February 19, 1885. (No model.)

T0 all whom t may concern:

Be it known that I, WILLIAM FRANK WIN- sHIP, of Albany, in the county of Albany and State of New York, have invented a new and useful Improvement in Raising and Lowering Devices for Vindows; and I do hereby declare that the following is a full, clear, and exact description of the same.

My invention relates to the raising and lowering of window-sashes; and its object is to dispense with the ordinary weights and cords now In use.

Another object of the invention is to provide means for the raising and lowering of windows where these weights are not used-as, for instance, in railway-car windows.

The invention consists in applying a rack or equivalent slotted plate to the edge or side of the sash, and a gear or pinion in a recess in the frame, adapted to mesh with the rack on .the sash, with operating mechanism from the gear tothe outer edge of the frame and a pivoted handle adapted to be folded into a recess in the frame.

In the accompanying drawings, Figure I represents a front view of a portion of a car sash and frame with a part ofthe frame broken away to show the operating mechanism, and also the anti-friction balls. Fig. 2 is a sectional view of the frame and sash, showing the anti-friction devices and the operating devices. Fig. 3 is a perspective view of an ordinary window frame and sash with a modified form of handle and locking device. Fig. 4 represents a detail View of a portion of the device shown in Fig. 2.

I have shown in Fig. l my invention as applied to a railway-car window; but it will be understood tlIatthe invention maybe used with equally good effect upon windows of dwellings and any other place where windows are to be raised or lowered. v

In the figure, A represents the frame of the window, and B the sash. This sash slides in the ordinary ways in the frame in the usual manner. Upon the edge a a groove is cut, rrunning the length of the sash, and in this grooveis fitted a raclebar, c, as shown. Instead of this, however, a slotted plate may be placed over the groove in the sash and secured ing in the frame, and the forward part extends through the frame to the outside, having secured to its end or formed therewith a. shell,

y, which fits within a corresponding recess or cavity in the window-frame. This recess or cavity is protected from wear and injury by a metal ring, h, flanged, as shown, to protect the top and side of the recess, and also to bear upon the edge of the shell g, to prevent it from working out. Vithin the shell at one side I pvotahandle, 17, upon a pivot-rod,7r, as shown.

It will be understood that when it is desired to raise or lower the window the operator grasps the handle i and turns it in one direction or the other, according to whether the window is to be raised or lowered. Vhen the window has reached the desired point, it may be locked in place by turning the handle upon its pivot-rod, which operation, while closing up the handle within the shell and out of the way, locks the said shell and consequently the window in position by a pin, Z, attached to the handle and projecting from the bottom there: of, entering openings m in the ring h, as shown Fig. 4. These openings are arranged at numerous points on the periphery of the ring on the side toward the sash, so that the window may be stopped and held at any desired position.

In order to make the movement of the window easy, and prevent it from binding through the lateral pressure imparted by the gear meshing with the rack, I recess or groove the opposite edge of the sash, as shown at b, and insert rollers b' b' therein, so as to allow them and thus bear on the frame, and, if desired,

this bearing-surface may be shod with metal.

In Fig. 3 I have shown the invention as ap Vplied to an ordinary window and in a more economical manner than that shown in Fig. 1.

IOO

Instead ofthe folding handle I have shown an ordinary handle and crank secured to the shaft of the gear. This is secured to the shaft so as to leave a space between the face of the frame and the crank-plate, and from this plate, projecting inwardly, are pins a, any suitable number being provided. Secured to the frame directly above or below the end ofthe shaft f is a sliding plate, o, held by screws, as shown,- and having at one end a slot and at the other a thumb-piece, whereby the sliding plate may be moved to engage one of the pins with the slot in the end ofthe said plate, thus locking the window in position.

4I have shown my device attached to the lower window; but it will be'obvious that it may also be applied to the upper as well.

I do not limit myself to the exact and special detailsof construction, as I may vary the parts in many ways, according to the class of work desired, and the form of the parts may also be changed greatly without departing from the spirit of my invention.

Having thus described my invention, what I claim is 1. A raising and lowering device for windows, consisting ofa rack secured to the sash, a gear carried on a shaft, and working in the window-frame, and adapted to mesh with the said rack, and a pivoted handle secured to the shaft of the gear and adapted to be folded into a recess in the window-frame, substantially as described.
