Application filed September 28, 1918. Serial No. 256,107.

To all whom it may concern:

Be it known that we, CHARLES M. Horr- MAN and J OSEPH TI-IOMISSER, citizens of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented new and useful Improvements in Automatic vestibule-Curtain Holders, of which the following is a specification.

This invent-ion relates to devices for holding the curtains connecting the bellows of adjacent vestibuled railway cars, and its object is to provide a novel and improved fastening which becomes automatically disengagedwhen the cars separate. Ordinarily, the trainmen must unfasten the curtains before the cars are ordereduncoupled and separated, and if this is overlooked the curtains are torn apart. The invention therefore effectually overcomes this difficulty, and all danger of damage to the curtains is eliminated.

ith the object stated in view, the invention consists in a combination and arrangement of 'parts to be hereinafter described and claimed, and in order that the same may be better understood, reference is had to the accompanying drawing forming a part of this specification.

In the drawing, j

Figure 1 is an elevation of the invention, and 7 Fig.2 is a horizontal section on the line 2-2 of Fig. 1, and

Fig; 3 is a fragment of the device showing a slight modification.

Referring specifically to the drawing, 5 denotes a fragment of the curtain, reinforced at its free edge'by a rod 6, and here carrying an elongated handle rod 7. On the wall 8 of the car toward which the curtain is to be stretched is mounted a device for holding the curtain in this position, This device comprises a pair of jaw members 9 and 10, respectively, having their opposite faces shaped to fit around the rod "7 when closed up. The rod 7 is tubular and fits loosely on a rod 11 secured to the free edge of the curtain "5 by clamps 12. v The' and forked at 22 to straddle the shank, to,

which latter it is connected by passing the cross pin 19 through the fork branches. This lever projects from the top of the housing.

The housing 16 has outstanding base flanges 23 for attachment to the wall 8 or other support.

It will be noted that the outer side edge of the aw member 10 is not parallel to the longitudinal axis of the shank 13 but has an outward curve, and hence when the shank is drawn inward, the edge of the slot 15 engaging this curved surface tends to force the jaw member over toward the fixed jaw member 9. The parts are so designed that the hinge or pivot connection 14 is inside the housing 16 when the jaws are closed, and hence the jaw member 10 now cannot PATENT,OFFICE, 7

accidentally swing away from the jaw member 9 to release the rod 7, and before the rod can be released, the shank 13 must be advanced to locate the jaw pivot 14 outside the housing, this being .done by the hand side the housing 16, the jaw member 10 is freed and swings back and allows the rod 7 to slip out of the jaws. The jaw members may be provided with the leaf spring 10 shown in Fig. 3, for automatically spreading the same when projected, so that it will not be necessary to pry them apart to insert the curtain rod when they stiffen from rust. We claim:

A holding device comprising a support having an opening, a slidable shank carried by the support and seating in theopening, a fixed jaw on the outer end of the'shank, a jaw pivoted to the shank and positioned opposite the fixed j aw, the outer side edge of to the shank for sliding the same in the the pivoted jaw engaging the edge of the posite direction.

openingand being non-parallel to the axis In testimony whereof we affix our signa- 10 of the shank, whereby said jaw is forced by tures.

said edge toward the fixed jaw when the shank is slid in one direction, and a hand I I CHARLES M. HOFFMAN. lever pivoted to the support andoonnected I "JOSEPH THOMISSER'.
