WINDOW-REGULATOR OPERATOR AND CLUTCH.

Application filed July 19,

This invention relates to a sliding window regulator operator and clutch. It is the object ot' the present invention to provide an actuatorl and a lock for window regulators which comprises a single lever which when pushed in either direction will automatically release the clutch and Jermit the window to be raised or lowered. n the other hand, when the thrustingeffort is released7 the clutch will lock and hold the winthe window well.

is a side elevation ot' the combined Fig. Q

clutch in its central or locking operator and position.

Fig. 3 1s a view of the clutch, similar to the same when it is being actuated to raise or lower the window. Fig. l is a section on the line 4.--4 of Fig. 2.

Fig. 5 is a section taken on the line 5-5 of Fig. 2.

It is desirable with the rear quarter windows of an automobile closed body to use a regulator operating` handle which is supported either on the horizontal bottom garmoulding or the vertical side garnish moulding of the car. This removes the handle trom a position below the seat where it is liable to catch on ladies garments. It is the object of the present invention to provide sash operator and lock which will automatically release when thrust in either direction. i slide of ythis general nature is shown in the prior Heintz Patent7 No. 1,430,647, but this requires the pinching 4o together of two levers before the release is effected.

Sliding sash holdersare quite common and have been used in connection with rear quarter windows. Most of these sash holdrequire a distinct unlocking movement, furthermore, they do not operate a window lift, but simply attach directly to the sliding sash. Transom openers are also in common use which combine a l'sliding 51) actuating device with a locking device, butl most of these work on the principle of releasing by pinching two levers together.

The object of the present invention is to 1924. serial No. 726,948.

provide a simple regulator which automatically unlocks when thrust is placed on the handle in either' direction. This is the principlc of operation now employed in most regulators which have a rotating crank handle, but so far as I am aware it has never been employed or worked out in the sliding window regulator handle.

a, designates a flanged channel like track which is secured to the inside of the window well below the garnish moulding b. The bottom flange of this track is preferably notched as at c. Fitted into this C-like cross section track is a sliding carriage d comprising a stamped metal member having a strap portion odset at the center to form the housing e while the ends of the strap are riveted to the liber strips f to make the slide noiseless and easily operated.

The housing has a pair of spring supporting lugs g struck out of the stock and around these is looped and anchored a wire spring 7L which in effect is a double wish bone or safety pin type of spring. The two ends of this double wish-bone spring engage the lug i which is stamped out of the rocking lever or lever .7'. This lever j is a sort of inverted T-shaped, with a pair of nubs f; at either end of the bar of the T to act as rockers, while the depending portion m that passes through the slot- 11, in the carriage stamping serves as a sort of keel or centerboard (to use a homely comparison) to prevent the rocking lever from being tipped over or getting out of its proper position and assembly. The lever cannot have a permanent fulcrum in the way of a stationary pivot, as it is alternately rocked on two separate fulcrums. It is desirable that it have something in the way of a keel member or centering device which will keep it from getting out of its proper place.

The depending portion 0 of the carriage stamping is connected by a pivot with the arm g which is part of the window regulating apparatus, more clearly shown and described in my co-pending application, No. 725,7 59. The lug z' is arranged to be engaged or shot into anyone of the notches c of the track when the lever y' is in its central position. It is obvious that it isl only rocked from this central position when the handle portion 1' is grasped to slide the carriage in either direction. IVhcn the handle is so grasped, the lever rocks on either one nub or the other as is plainly shown in the full line and dotted line in F ig. 3. This serves to lift the lug out of the notch and release the carriage, and consequently unlock the sash.

The apparatus that I have here shown forms a positive lock for engaging the window. It will be obvious, however, that the notches could be omitted and the lug modilied to torni a trictional engagement with the track, which would probably take a much stronger spring, but which plainly comes within the spirit ot my invention and hence is incorporated with the breadth of the claims stated below.

lVhat I claim is:

l. A sliding window operator and clutch. having in combination a track and sliding hand lever guided along the track and arranged to lock on the track at any one ot' a plurality ot points while in its central position, but released when rocked in either direction when one grasps the handle to slide the operator.

2. A sliding window operator and clutch having in combination a track, provided with notches, a carriage guided along the notched track, and ahandle by which the carriage is moved, arranged to normally engage one of said notches but automatically lifted out of the notches when the handle is moved.

3. A sliding window operator and clutch, comprising` a track, a slidable carriage guided on the track and a hand lever rockingly mounted on the carriage and normally locking at any one ot' a plurality of points on the track against sliding movement ot the carriage, said lever however fulcrumed so as to release the lock when thc lever is actuated to slide the carriage.

4. A sliding window operator and clutch, having in combination a track, a sliding carriage guided on the trackl and a double fulcrumed hand lever mounted on the carriage which normally locks with the track at any one of a plurality ot points against movement of the carriage on the track when in undisturbed position, but which rocks to release the clutching action when actuated to slide the carriage in either direction.

5. A sliding window operator and clutch, having in combination a track, a carriage slidably guided on the track, a double ulcrumed hand lever supported on the carriage and normally centralized by a spring, and serving when in a central position to lock the carriage against sliding on the track, but rocking when actuated in either direction to slide the carriage so as to release automatically the carriage from its locked relation with respect to the track.

G. A sliding window operator and clutch, comprising a carriage, a track on which the carriage is guided, a lever having a pair oi2 tulcrums and a depending centering device, and a spring tending to hold the lever in its central position to lock the carriage against sliding movement on the track, whereby when the lever is grasped to slide the carriage in either direction, the same rocks on one tulcrum or the other to release the carriage from a locked relation with respect to the track.

7. A sliding window operator and clutch comprising a notched track and a device including a hand lever slidably guided on the track, the said lever being ordinarily spring pressed to have a portion engage with one of the notches of the track, it being rockable, automatically to release from the notch when the lever is operated to shift the device along the track.

8. A sliding window operator and clutch, comprising a track having a C-like cross section, a carriage in the form ot a stamping` having portions engaged in the channelsl formed at the top and bottom ot the C to establish a sliding relation between the track and the carriage, and a lever tulcrumed on the carriage and arranged to engage with the track when in undisturbed position, and a spring for maintaining the lever in engage ment with the track said lever however t'ulcruming on the carriage to release it from the track when actuated to slide the carriage on the track.

In testimony signature.
