UNITED STATES EMIL H. JACOB, OF CHICAGO, ILLINOIS.

ANTI-WINDOW-RATTLER.

Application filed August 20, 1919.

To all whom it may concern:

Be it known that I, EMIL H. JACOB, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Anti-VVindow-Rattlers, of which the following is a specification.

In the manufacture of certain grades of window frames constructed of wood, it is common practice to provide guideways for the sash of sufficient width to insure at all times free action of the sash in its manipulation to open and close a window. This width of guideway while quite desirable in the respect mentioned, permits of undesirable rattling of the sash as in windy weather, and also prevents certainty of securing a tight joint at the parting rails of the sash when the window is closed unless some means is provided to offset these faults.

The object of the present invention is the provision of means adapted, when the window is closed, for applying yielding pressure to force the sash of a window toward the strip which separates their respective guideways, thereby to prevent rattling and to maintain a close joint at the parting rails. To this end the invention consists in a novel application of bowed springs, housed within mortises of the sash and cooperative with elements supported by the window jamb or casing.

In the drawings accompanying and forming a part of this "specification there is shown. in detail one convenient form of embodiment of the invention which in order that it may be clearly understood is fully set forth. in the following description, while the novelty of the invention is defined in the appended claims.

In the drawings,

Figure 1 is a vertical sectional view of window construction embodying my invention.

Fig. 2, is a sectional view on line 2-2 of Fig. 1.

Fig. 3, is an edge view of a window sash mortised and equipped in accordance with the invention.

Similar characters of reference designate similar parts throughout the several views of the drawings.

Referring to the drawings, the numeral 3, designates a portion of a window casing of ordinary construction having the usual guideways 4 and 5, respectively for the Specification of Letters Patent.

upper sash 6, and the lower sash 7. The guideways are separated by the strip 8,

and clearance for the sash in each guideway is indicated at 9. The

parting rails

10 and 11, respectively of the upper and lower sash are represented in Fig. 1, in the relation they bear to each other when the window is closed. Obviously the joint 12, between these rails, would, in the absence of means to prevent it, be subject to separation equal to more or less of the clearance in each of the guideways, therefore in providing for the application of pressure to prevent vibration of the sash, I prefer that it be directed to force the sash against respective walls of the guideways formed by the strip 8. My invention contemplates the use of bowed springs for effecting the desired pressure against the sash, and one of these is preferably provided near each of the four corners of each sash, although a lesser or greater number may be provided according to requirements.

Each sash is grooved as at 13, along each of its guideway engaging edges to receive and provide clearance for stationary elements as pins 14, projecting from the window casing at suitable points to en age respective springs as 15, carried by t e sash, such engagement being effected when the sash are moved respectively to window closing positions. Each of these springs 15, and the manner of applying it, is the same, so a description of one of them and its relation to the sash and window casing will afford an understanding of their combined action.

A spring of suitable form to fulfil the requirements of my invention is bowed intermediate its length, as at 17, and terminated in reversely

curved ends

18 and 19. For the reception of such a spring in the edge of a sash, a mortise or recess 20, is provided which intersects the groove 13, and which has a wall 21, substantially coextensive with the spring when the latter is extended by compression of its bowed portion, (see Fig. 1) the extremities of the wall being curved to correspond to the curved ends of the spring.

Preferably, though not necessarily, means are provided to retain the springs in their respective recesses, and staples as 22, are effective for this purpose, one being applied near each end of the spring and driven into the sash, ample clearance being left between the staples and the spring to insure free action of the latter when it engages its cooperating element or pin 14, supported in the window casing.

From the foregoing description it'will be clear that as the sash are moved into their window closing positions, the springs 15, ene gage their respective pins 14, and press the sash respectively toward opposite sides of the strip 8, thereby serving effectively to prevent rattling of the windows and to bring the parting rails intoa close-joint relation; While the springs are positively retained against diplaoernent from operative position, it will be noted that they are loosely held thereby permitting. a natural distribution of fiexure which insures an ease of action requiring little effort in operating the sash.

Having thus described my invention, what I claim is,

1. In combination with a sliding window sash and its casing, anti-rattling construction including a pin in one of the members ada ted to relativel Y traverse a oath defined 25 by a groove in the other member, said groove being covered throughout the normal path ofthe pin by a single wall of the pin carrying inernbeig and a bowed spring extending into thepath of the pin and freely retained 30 in a recess in aside wall of the groove.

2. In combination with a sliding window sashand its casing, anti-rattling construction inoluoing a pin in one of the members ada oted to relativel traverse a oath defined 35 by a groove in the other inen'iber, and a bowed spring extending into the path of the pin, the ends ofthe spring being reversely curved and retained in a recess in a side wall 0% the groove saidrecess having end sent H. i ooB.
