NiTEn STATES PATENT WINDOW SASH AND FRAME..

SPECIFICATION forming part of Letters Patent No. 383,134, dated lvliay 22, 1888.

Application filed December 20, 1886. Serial No. 222130.

To all whom, it may concern.-

Be it known that I, CONRAD KRUEsI, a citizen of Switzerland, residing at Chicago,in the county of Cook and State of Illinois, have invented a certain new and useful Improvement in W'indow Sash and Frames,of which the following is a specification, to wit:

This invention relates to an improvement in window sash and frames; and it consists in certain novel details of the construction and arrangement of the same, whereby the sash is more readily removed and replaced and is locked and heldat any place, substantially as Will be hereinafter more fully set forth and claimed. y

In order to enable others skilled in the art to which my invention pertains to make and use the same, I will now proceed to describe its construction and operation, referring to the accompanying drawings, in which- Figurel is a front elevation of a window frame and sash fitted as I shall describe. Fig. 2 is a central vertical section of the same; Fig. 3, a horizontal section of the same. Fig. 4 is an enlarged detail cross section of a part of one ofthe sash-rails and my fastenerand guide. Fig. 5 is a detail front elevation of the guide partly brokenaway. Figs. 6 and 7 are views similar to Figs. 4 and 5, but representing the device in a different position. Fig. 8 is a plan view, and Fig. 9 an edge View, of the casting in which the guide is hinged. Fig. 10 is atop view, and Fig. 1l a side view,of my device for securing the sashcord.

A represents a window-frame of any suitable size and shape, and either with or without the usual weightwell, according as it is desired to use a balanced sash or not. This frame is on its inner sides provided with two shallow vertical grooves, b,instead of the usual dividing and guide strips; and while the form of these grooves may be greatly varied to suit dil-'ferent circumstances, I prefer the shallow halfround form shown in the drawings. These grooves being sunk in the frame leaves the entire face of the frame smooth and free for the insertion and removal of the sash, as will be presently explained.

The upper and lower sash, B C, are made, in the usual manner,of a size to tit the frame.

(No model.)

are forced into these grooves by means of small eccentric levers ef, pivoted upon studs g It' on the side rails of the sash. The eccen` tric levers work against wings p on the leaves a c, which project forward and are turned over the front of the sash. As seen in Figs. 5 and 7, these levers are eccentrically pivoted, leaving upon one side of the pivots asmall part, ef, and upon the other a larger portion, c fi, and it will be evident that when these levers are turned to press their larger sides against the hinged guides these latter are forced into the framegroovcs with varying force, either to serve as a guide for the sash in being raised or lowered or so tightly as to iirmly lock the sash and eft'ectually prevent its being moved. Vith this device to hold the sash the window can be perfectly secured at 'any point without the aid of balance weights; but I prefer to use such weights,and secure their supporting-cord H, knotted at its end,in a small metallic socket, F., which is provided with a screw, Cr, to secure it to the sash, and has in one side an angular slot, 7i, opening through the outer edge of the socket, as will be understood from Figs. l0 and 11. The cord is readily inserted and removed from the angular slot, and is securely held in place when the sash is in the frame.

The operation of this device is at once plain. The sash, when placed in the frame, is guided in lifting and lowering by the hinged leaves or guides a c, which run in the grooves b d in the frame and retain the sash in place exactly as is done by the stops and beads in common use. Vhen the sash is to be locked in any position, either closed or partially or wholly open, the eccentric levers are simply turned to press the hinged guide leaves more firmly into the IOO grooved frame, and thus firmly secure the sash perfectly immovable. When the sash is to be taken out for cleaning or repairs, it is only necessary to turn the eccentric levers in the opposite direction, and the guide-leaves can be swung out on their hinges and leave the sash free to be drawn out of the frame and returned again without the use of tools of any kind. The convenience of this will be seen at a glance, and also that the hinged leaves are readily adjusted for shrinkage or swelling ofthe sash, caused by variations of Weather, and take up all looseness and rattling.

The particular form of the hinged .guideleaves and their size will of course be regulated according to the dictates of fancy or the requirements of particular cases, and may be made of fancy form and ornamented according to taste or desired economy of construction.

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

1. The combination, with a Window-frame formed with grooved sides, of asash provided with guides pivoted to the sash and provided With' tongues to t into the grooves, and projecting wings projecting in front of the sash,

'and means, substantially as described, for operating said guides.

2. The combination, With a Window-frame formed with vertically-grooved sides, of a sash having its edges recessed, guides or leaves hinged in said recesses and projecting beyond the face of the sash, and eccentric levers pivoted upon the sash-rail and bearing against the projecting hinged leaf to press it into the groove with the required force, substantially as shown and described.

In testimony whereof I afx mysignature in the presence of two Witnesses.

CONRAD KRUESI.
