WINDOW-SUPPORTING LATCH.

Specification of Letters Patent.

Patented June 14;, 1921.

= Application filed October 16, 1920. Serial No. 417,433.

To all whom it may concern:

Be it known that I, EMORY GLENN SIMP- soN. a citizen of the United States, residing at Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Window- Supporting Latches, of which the following is a specification.

This invention relates to a window-supporting device or latch for use in connection with automobile closed bodies. The prevailing way to support a window in its upper position is to provide a so-called fence over which the window is lifted or hooked. This construction, however, is open to the disadvantage that the window guide must be wider than the window edge and hence often permits vibration or rattling of the glass. Another way of holding the window up is by the use of a window regulator. This raises and lowers the window mechanically and is provided with suitable clutching mechanism to keep the window in any position. The conventional types of window regulators however, have not so far been found very successful in connection with the rear quarter window.

It is the object of the present invention to provide a simple form of device which may hold the window in its raised position after it has been raised with the ordinary strap. This permits the use of the vertical window guides that are made substantially the width of the window.

In the drawings,

Figure 1 is a fragmentary view of the inside of the closed body adjacent the rear quarter window showing my window latch.

Fig. 2 is a front elevation of the window latch.

Fig. 3 is a section on the line 3-3 of Fig. 1.

a designates a plate which can be secured to the body of the car below the window sill. The body of the car adjacent the window will be called the window frame. This plate is provided with a slot 6 and under this slot a pressed-in or countersunk portion 0 to permit the finger of the operator getting in under the ring 03 which is attached to the latch. The escutcheon plate a has turned-back ears awhich support the pin 7. The latch itself is simply an elbow formed by a single stamping having turnedup sides or reinforcing ribs 2' and having the prongs it at one end to form the knuckle for the pin 7 and having the opposite end turned over to form the knuckle j to receive the ring cZ. it will be noticed that the top of the elbow has a beveled or slightly curved surface to permit the latch to wedge in under the bottom of the channel 72 that supports the-window Z.

m designates the usual pull strap by which the window is raised. The latch is located directly under where the pull strap ordinarily hangs so that one may grasp the pull strap and the latch handle at the same time to let the window down. All one has to do is to grasp the ring (Z and pull the latch in. This allows the window to drop and the operators hand being on the strap he may see to it that the window does not drop too rapidly.

The torsional spring a wound about the center of the pivot pin f serves to normally keep the latch projected into the window pocket, but of course as the top of the window is raised it strikes the side arm of the latch elbow and forces the same in. Ordinarily when the strap is in position this will tend to first force the latch in and the latch will bear against the inside of the strap as the window is being raised and also when the window is being What I claim is:

1. In a window construction, the combination of a frame provided with a window pocket, a window slidable vertically therein, and a latch comprising an escutcheon plate securable to the window frame and provided with an opening therein, an elbowlike latch member pivoted at its lower end and having its upper free end adapted to protrude through said opening, a spring for ordinarily forcing the latch into the window well, and the joint portion of the elbow into the path of travel of the window and means secured to the free end of the upper arm of the elbow for drawing the latch member out of the window well to allow the descent of the window.

2. In a window construction, the combination of a window frame provided with a window pocket, a window slidable therein, and a latch secured to the window frame, comprising an escutcheon plate having an aperture, an elbow-like latch member pivotally supported at its lower end upon the said escutcheon plate and having its upper dropped.

in the front of the escutcheon plate, a ring secured to such part of the elbow member by .which the same may be drawn out of the window welhand aspring tending to urge the elbow member into the window well and the joint portion of the elbow into the path of travel of the window to support the window when elevated.

3. In a window construction, rthe combination of a window frame provided with a window pocket, a window slidable therein, and a latch secured to the window frame, comprising an escutcheon plate having an aperture therein and below the aperture' a pressed-1n or countersunk portion, an

elbow-like latch member pivotally supported by the escutcheon plate at its lower end and having its upper arm protruding through the aperture in the escu'tcheon plate, a ring supported in such end of the elbow and hanging down along the pressed-in portion of the escutcheon plate, and a spring tending to urge the elbow-like latch member into the window well, the said latch member serving to support the window in ele-- vated position when projecting into the window pocket.

In testimony whereof I affix my signature.

V EMORY GLENN SIMPSON.
