ANTIIRATTLIN-G MECHANISM roe wrix'rnows.

I j Applicationfiled' April 26, i922. Serial Nd, 556,595.

To all whom it may concern:

Be it known that I, EDWARD EDWARD RICHARDSON, a citizen of the United States, residing at Maumee, in -the county of Lucas and State of Ohio, have invented certain new and usefullmprovements inAnti- Rattling Mechanisms. for Windows, of

cise', and exact description of my invention,

such as will enableothersskilled in the art to which it appertains to make and use the same. i I

to I such device as will prevent the unpleasant rattling of glass" windows of enclosed automobiles, although my invention is not limited to such a use. 7

An object of my invention is to provide ananti-rattling mechanism adapted to be used to prevent. the vibration of a glass window, such as employed in enclosed automobiles, by the application.of pressure resiliently applied to the surface of such a window, near the edge thereof.

A further object of my invention is to provide such mechanism as maybe simplc to operate, but which may be capable of applying a considerable pressure, re-

siliently, to the-window pane, and which willbe capable of being; set in operative condition by a simple single operative n ov'en'ient by the operator and which when sorset will remain in set' position against the portion of contributing causes which in prior constructions have been eflected to restore the mechanismto inoperative condition, such contributing causes being vi-.

bration caused by rough roads, etc. t

Another object of my invention is to'pro vide an inexpensively constructed mecha: nism of the kind described, made principally of sheet metal and of very few parts and which may be assembled or disassembled repeatedly and Without any particular skill on the partof'the assembler.

Another object of my inventionis to provide amechanism as described,which may be easily placed on the casing adjacentthe window pane and which will remain in operative condition for longperiods oftime wvithout attention, and which will moreover, give a presentable appearance, adding rather than detracting from the appearance of thec ar to which it is applied.

Other objects offmy invention and the by reference to the drawings forming a part of this specification, and inwhich drawifngs Fig. 1 shows an 'elevational view of the .mechanism of my invention in normal, un-

attached, inoperative condition.

Fig. 2 shows an elevational view of the mechanism of Fig. l, the parts beingin v the mechanism. My invention relates to anti-rattling" mechanisms for, windows,v and particularly to awindow casing adjacent a windo-w ane,

the parts being .111 operatlve ad1usted posi tion to restrain vibrations of the saidw1n'-- dow pane.

. invention itself will be better understood 'Fig; 5 shows "a top. plan view of the mechanism as'shown in F1 4.

Fig. "6 shows a view similar to Fig. 2,'but with the operating lever of the mechanism thrownto full operative position.

Referring now to the variousfigures,in

all of which like parts are designated by like referencecharacters, at 1 I show the enclosing casing for a mechanismembodying my inventiomsaid casing having a front outer wall 2,end walls 3 and 4 and portions of end walls 5 and 6. The side of the casing opposite the wall 2 being left open as are also portions of the walls 5 and 6 for purposes later to be described.

Thecasing 1 is as'shown formed of sheet metal, the side and end walls being turned up from the outer wall 2 and at right angles thereto, a portion of the wall '5 being omitted so as to provide an opening 7 through which the spring vibration subdulng element 8'is adapted to pass, portions of the spring 8 occupying different positions through the opening 7 according to the different operative positions of the spring and due to the flexing of the spring 8 in the different adjusted positions thereof. The wall 2 has also a turned up portion9, over which flange portion 9, a cainming lever 10 fitted, the lever 10 having an opening 11 adapted to encompass the said flange 9,'the

wall 6 base portion omitted from either side oftlie flange 9 for the retaining of the lever 10' and the cam portion 12 thereof, said 'cam portion being suitably formed so as to have acamming edge 13, adapted to engage the spring 9. at an intermediate portion 14. The spring 8 is placed within the frame 1 with its end 15 resting against the wall 5 and the spring 8 being bent around between the wa ls 5 and 6 and the cam surface 13 of the'lever 1.0 and around a pin 16 secured at its end to the base 2 the frame 1. The spring 8 thus has anormal tendency tending to move the soft rubber cap 17 placed on its end away from the pane of glass shown 18.,The end of the spring 8 is suitably made irregular in shape as indicated in Fig. 3 at 19, and the rubber cap 17 is made of such size that it must be stretched in order to fit over the spring 8.

When the anti -rattling device of my invention is placed in service, it is secured by means of wood screws 20 and 21, passing through openings 23 and 24 through the case 1, and into the casing 22 of a window frame having the window pane shown at 18. Vihen the lever 10 is in inoperable position as shown at Fig. 2, the cap 17 rests but lightly, if at all against the window pane, but when the lever 10 is thrown to the position indicated in Figs. 4 and (3, the cap 17 is moved against the window pane 18 and I exerts a considerable pressure. thereagainst,

the pressure being resiliently applied through the resilience of the material of the cap 1? and the spring 8.

The resiliency of the pressure contributes to the prevention of rattling at all times. and at the same time where a plurality of my improved devices are in use on different portions of the window pane simultaneously, the window pane will not be placed under such a severe unyielding stress will cause the pane to break when vibrated sharply.

It will be noted also that approximately at the point 25 of the cam face 13. the said cam. face surface 18 is disposed further from the center of rotation of the lever 10. The center of rotation being indicated in Fig. 6 by the numeral 27. Therefore. when the lever 10 is thrown to its completely operated position the point 25 on the cam face has just passed that position whee it contacted with the spring 8 and another point 28 on the said cam face less distant from the center of rotation 27 in contact with the spring 8; in other words. the cam is rotated past the dead center operative posi- "tion. This contributes towards the performance of the function of maintaining the lever of set operated position under the sustaining pressure of the operated spring 8.

Having thus descr'bed my invention in a specific embodiment, I am aware that numerous and extensive departures may be made from the embodiment herein illustrated and described, but without departing from the spirit of my invention.

What I claim as my invention is:

1. in a device of the class described, a

substantially open ended rectangular box shaped base member, opposite sides of said boX member having openings therein, a fiat leaf spring secured at one of its ends within the said base member near an end thereof, and having its other end projecting through one of the said side openings, a camming lever journalled in the said box member and having a handle portion projecting through the other said opening, means whereby said base member may be secured to the frame of a window with its open cndin contact with my improved devices are in use on different the said frame and the end of the said leaf spring adjacentthewindow pane; said camming lever adapted to press the end of the said spring firmly against the window pane when the said handle is operated, and a pad of resilient material carried by the said spring end pressed against the window pane.
