PULL-STRAPv FIXTURE.

Application filed May 18,

To all whom it may concern:

Be is known that I, PAUL RISSMANN, 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 Pull-Strap Fixe tures, of which the following is a specificati on.

This invention relates to attaching fixtures for securing a pull strap to a window sash. I In automobile closed body construction the so-called pull strap is still used on some windows. This strap is now usually made up of a center of burlap strips and has a backing of waterproof fabric and a face that is usually trimmed in the same goods with which the car is trimmed. It is customary ordinarily to attach these straps to the metal channel bar that forms the lower support of the sash by means of a loop. A metal loop is usually provided on the side of the channel bar and the pull strap is looped through this and then stitched to form a loop. The trouble With this construction is that it frequently tears out because the stitching or material is not strong enough to stand the very severe tension that is often put on the strap especially if the window sticks.

It is the object of the present invention to provide an attachment which comprises a strap fixture which may be quickly attached to the ends of the strap and which may be detachably engaged with a special fixture secured on the bottom of the sash bar.

In the drawings,-

Fig. 1 shows the usual interior construction of a closed body indicating the pull strap.

Fig. 2 shows how the pull strap is fastened to the bottom of the sash. This is simply a fragmentary view of the bottom of the window.

a designates the ordinarypull strap which is adapted to raise and lower the Window 7). These windows are now made with no sash bar at the top'and frequently none at the side. However, they have a channel bar 0 Specification of Letters'Patent. Patented Aug, 15, 1922 1921. Serial No. 470,648. I

the glass rests. Atthe bottom of this channel bar is spot-welded or riveted a sash fixture d which comprises simply a strip of metal stamped out as shown in Fig. 5, form-.. mg a loop e having a pair of ears fpf ex tending forward.

The strap fixture comprises an angle plate or stamping go {One web 1 of this angle plate is, provided with extending ends it. The. other web 8 is provided with struck- 1n prongs 7'. The clamping plate is is adapted to match the web 8 of the angle plate and at the bottom'in whichthe lower edge of I is provided witha plurality of struck-in v projections Z at the endof which are;slo ts m. able dies to hold the angle plate 9 and the clamping platelc. The end of the strap can be interposed between the two plates and the prongs j can be driven through the strap ,70 A machine can be provided with suitend and through the slots m of the plate k. i

The prongs are then turned over by the press I into the depressions Z which are just the shape to nicely receive them. This avoids their projecting to any extent above the surface of the plate k and makes a neat, clean job of it.

When this has been done the fixture is neatly attached to the pull strap with the end extensions extending to the sides of the strap. The strap may then be inverted, as shown in Fig. 2, the back of the strap facing the observer. The web 1- with the end extensions h is then slipped into the loop 6. The ears 7 are then simply bent up beyond the end extensions h, locking the fixture into the sash fixture.

These two fixtures not only form a attachment for the pull strap to the window sash but the strap fixture forms a very neat salvage for the end of the strap. The strap fixture may be applied by a suitable set of dies and a small press very rapidly so that strong the article is a large production proposition.

4. An attachment. for securing pull straps to Window sashes, having in combination, a fixture in the form of a stamping provided with a loop portion and having forwardlyfacing ears at the ends of the loop portion, and a pull strap fixture comprising an angle plate provided with a Web having end extensions adapted to be locked in behind the ears of the Window fixture loop When the ears are turned up right-angularly, the other Web of the angle plate being provided With struck-out prongs, and a clamping plate havingslots adapted to register with said prongs when the prongs are impaled through the end portion of the pull strap, the said prongs being then passedthrough the said openings in the clamping plate and turned over to complete the pull strap fixture.

In testimony whereof I aflix my signature.
