' 6 Claims (crass-426i This invention relates to a window operating mechanism and has relation more particularly to a mechanism of this kindincluding a lever operatively engaged with the window proper thus making it possible to produce an operating mechanism for rapidly moving the window into open or closed position. a

The invention has for an object to provide a mechanism of this kind so constructed and arranged to allow a rapid movement of a window into open or closed position as a result of but a slight turn of an operating handle in contradistinction to themechanisms now generally in use wherein a number of .complete turns of the operating handle is necessary in order to'move a window into either fully open or closed position.

The inventionalso has for an object to provide a mechanism of this kind including an operating lever for operative connection with a window and wherein said lever is so constructed and arranged to impose a push or pull as required upon the window without shifting the operative connection or engagement of the lever with the window. a

A still further object of the invention is to provide a mechanism of this kind constructed and assembled in a manner to move a window into open or closed position without chattering and free of rubbing against or sticking to the frame or guide members for thewindow, thus assuring desired adjustment or shifting of the window without strain to the operator.

The invention consists, in the details of construction and in the combination and arrangement of the several parts of my improved window operating mechanism whereby certain important advantages are attained and the device rendered simpler, less expensive and otherwise more convenient and advantageous for use, as will be hereinafter more fully set forth.

The novel features of my invention will hereinafter be definitely claimed.

In order that my invention may be the better understood, I will now proceed to describe the same with reference to the accompanying drawings, wherein:-

Figure 1 is a fragmentary elevational view of somewhat a diagrammatic character illustrating an operating mechanism for a window constructed in accordance with an embodiment of 'my invention;

Figure 2 is a view somewhat similar to Figure 1 showing certain of the parts in asecond position;

Figure-3 is a view in top plan of the structure as illustrated in Figure 2;

Figure 4 is a fragmentary sectional view taken substantially on the line .4-4 of Figure 1;

Figure 5 is a fragmentary elevational view of the side opposite to Figure 1 and particularly illustrating the balance spring ooacting with one of the gears. i

My improved mechanism as herein disclosed is particularly adapted for use in connection with a vertically movable glass closure member M such as is now generally used in connection with automobile bodies. This member M is mounted in any or the different ways now known for desired up and down movement in substantially a fixed path of travel, and as such mounting in itself forms no part of the present invention it is not believed, that a'detailed description and illustration thereof is required.

The lower marginal portion of the closure member M at preferably its longitudinal center has pivotally connected therewith, as at I, an end portion of a lever 2 of desired length. The end portion of the lever 2 remote from its. pivotal connection with theclosure member M is pivotally connected, as at 3, with the outer portion of an arm 4 extending radially from and preferably integrally connected with a pinion 5 of desired diameter. This pinion 5 is mounted for rotation upon a stub shaft 6 carried by and extending laterally froma chassis I. This chassis 1 or supporting member is mounted in any preferred' manner within the well below a window opening in either a door or side wall of a vehicle body. c

The pinion 5 constantly meshes with a second pinion 8 fixed to rotate on the shaft 9 rotatably supported by and disposed through the chassis The chassis I carries a bearing l through which the shaft 9 is also directed,

The shaft I0 extends beyond the face of the chassis I opposite to the pinion 8 and secured, as at H, to said extended portion of the shaft 9 is an end portion of a helical spring l2, the opposite or outer end portion of which being anchored, as at [4, to a post extending outwardly from the chassis I at the same side as the spring l2. This spring I2 serves as a balance spring as will herematter be referred to.

The pinion 8 as herein disclosed is integrally formed with a segmental gear It, the radius of this gear I6 is materially greater than the radius of the pinion 8 and the axialcenters of the pinion l6 adjacent to its periphery carries an outstand ing pin H which extends through a slot IS in the lever 2 and extending lengthwise thereof. The pin-l1 is of a diameter substantially equal to the width of the slot iii. The arm 4 of the pinion 5 is of such length-that as the gear I6 is rotating in either direction, the pivotal point i on the lever 2 will move up or down in a straight line as indicated at a. in Figures 1 and 2. This is important as .a similar pull is assured at 'all times upon the closure member M when being either pushed or pulled into fully open. or closed position. This is of advantage as chattering is avoided and the member M has movement without resistance being offered by such movement as by rubbing or sticking to the conventional guideways for the member M. I

The gear it constantly meshes with a segmental gear l9. In the present embodiment of my invention this gear is is illustrated as being on the same radius as the gear i6. This, however, can be varied in accordance with the preferred speed at which it may be desired to have the gear l6 operate.

This gear i9 is fixed to rotate with a shaft 20 disposed through the chassis or support I and said shaft 20 has engaged therewith in a conventional manner an operating handle ii. In Fig-. ure 1 the closure member M is illustrated in its fully. lowered position whereas in Figure'2 the lever 2 is shown in its position when the closure member has been moved into half way position with respect to its opening. Attention is directed to this in view of the fact that it is to be emphasized that in order to move the closure member M into either fully open or closed position only approximately a one quarter turn of the handle 2! is required which is in contradistinction to the window operators now generally in use wherein the operating member or handle of necessity must be fully rotated a number of times.

As the mechanism is operated to move the closure member M downwardly, the balance spring I! is placed under tension so that when the mechanism is operated to raise the member M such upward movement will be facilitated by the action of the spring l2 and thereby materially minimizing the effort onthe part of the operator. It is to be stated, however, that the spring I! in itself is at no time of a tension sufficient to automatically raise the closure member M.

From the foregoing description it is thought to be obvious that a window operating mechanism vention is practice except as hereinafter claimed.
