WILLIAM GRIFFITH TRETI'IEWEY, OF TORONTO, ONTARIO, CANADA.

VESTIBULE-HOOD FOR CARS.

Application filed January 24, 1907.

To all whom it may concern:

Be it known that I, WILLIAM GRIFFITH TRETHEWEY, of the city of Toronto, in the county of York, in the Province of Ontario, Canada, have invented certain new and use ful Improvements in vestibule-Hoods for Cars, of which the following is the specilica tion.

My invention relates to improvements in vestibule hoods for cars, and the object of the invention is to devise a simple, cheap and durable form of car vestibule hood by which the door ways in the vestibule may be connected to each other and it consists essentially of a vestibule hood formed of flexible material, such as rubber substantially U- shape in ross section around the sides and top and secured in place as hereinafter more particularly explained.

I are 1, is a side elevation showing two cars equipped with my improved form of hood. Fig. 2, is a face view of my hood. Fig. 3, is an enlarged sectional plan. Fig. 4, is an enlarged sectional detail showing the manner of fastening the edge to the face of the vestibule.

In the drawings like letters of reference indicate corresponding parts in each figure.

A A are two cars and A A are vestibules thereof.

B are the vestibule hoods and O the platform. I

A are the side posts or panels of the doorway of the vestibule.

B is the encompassing outer frame of the vestibule, which is made preferably of iron and secured to the central floor plate C.

D are the flexible curtains of the hood which are preferably made of rubber or other suitable conntosite material having cotton as base. The curtains D extend from the bottom of the frame B around the top of the hood and is substantially U-shape in cross section as indicated in order to allow of contraction and expansion of the hood. To cause the curtain to retain its U-shape uniformly when in use it is preferable to reinforce its web from its center toward its edges. This may be attained by the employment of any flexible material that the manufacturer finds most adaptable.

E are the fastening bars preferably made of Specification of Letters Patent.

Serial No. 353,889.

wood,which lie along the edges and parallel with the same, and F are metal washers, 'hia-h extend over the bars E and prevent their spreading.

G are bolts, which are located at desired distances apart and are threaded at the inner ends into the panels of the vestibule door and the projecting ends which pass between the bars E and are also threaded to receive the fastening nuts G which abut the washers l The inner edge of the curtain as indicated in the drawings is fastened to the doorway frame of the vestibule and the outer edge to the frame B as indicated.

By such a construction of hood as I have described I am enabled to avoid the cracking and breaking, which is so commonly incident to the bellowslikc form of hoods for vestibules now commonly employed.

What I claim as my invention is:

1. In a vestibule hood for cars, an independent curtain for the end of each car U-shaped in cross section, fastening means connect g the inner edge of the same around the duel- Way of the vestibule, an outer frame, and fastening means for connecting the outer edge of the hood to the outer frame, the curtain at the edges where it is connected to the fastening means having a reinforcing thickness as and for the purpose specified.

2. In a vestibule hood for cars, a curtain formed U-shape in cross section with the center portion weakened or thinner and the edges reinforced or thickened, and suitably fastened to the frame of the hoodv and the doorway and vestibule as and for the purpose specified.

3. In a vestibule hood'for cars, the combination with the vestibule doorway and curtain, of a fastening means for securing the curtain at each edge around the doorway comprising divided parallel bars, washers straddling the same and bolts extending through the washers and between bars into the frame or doorway, and suitable iuts on the outer ends of the bolts, as and for the purpose specified.
