FFICEQ NEW ORLEANS, LOUISIANA, ASSIGYOR AND ROBERT H. SIMONS, OF NEIV OR- VESTlBULE-CAR.

SPECIFICATION forming part of Letters Patent No. 782,025, dated February '7', 1905.

Application filed June 29, 1904. Serial No. 214,614.

be it ltnown that I, JULEs ALLoU DHmtn eoturr, a citizen of the United States, and a resident of New Orleans, in the parish of Orleans and State of Louisiana, have invented a new and Improved vestibule-Car, of which the following is a full, clear, and exact description.

My invention relates to the vestibules of cars. and more particularly to those which extend the full width of the car and have the space between the platform and outer door closed by atrap. In such a structure the ordinary practice is to operate this trap from the inside before opening and after closing the door. the preparation for egress and ingress requiring two distinct operations.

To furnish means for simultaneously operating the door and trap is the principal object of my invention: and with this end in view it consists in the various features and combinations hereinafterdescribed and claimed.

Reference is to be had to the acompanying d rawings, forming a part of this specification, in which similar characters of reference indicate ;:orrespomling parts in all the figures.

Figure I is a perspective view of a portion of the end of avestilmle-car to which one embodiment of my invention is applied. Fig. 2 is a partial bottom plan view thereof, showing the door and trap partly opened. Fig. 3 is a similar view illustrating another position of the elements. Fig. a is a vertical section showing the parts stilI further opened, and Fig. :3 is a bottom plan view in which the door and trap are fully opened.

L designates a car having a platform P and a vestibule structure V extending over the steps S to the full width of the car, in which vestibule there is a door D. Filling the space between the end of the platform and the door when the latter is in its closed position is a trap, which is here shown in two sections 10 and II. The former or main section is secured to the end of the car by hinges 12 12, which permit it to be turned up against said car. the section 11 being pivotally mounted upon the section 10 by hinges 13 13. Both sections may be supported at their ends opposite the car by a ledge 14, while the section 11 may receive further support by the manner of attachment of the hinges, which being upon the upper side bring the adjacent edges of the sections together and prevent their opening beyond horizontal alincment. The bottom of the door may be provided with a transverse strip or head 1%, extending beneath the trap and serving to close the space between the elements against the entrance of air and dust.

Fastcncd to the end of the car beneath the trap is a plate 15, having upper and lower flanges 15 extending toward one another and furnishing ways in which moves a slide 16. This slide is connected with a plate 17, fixed to the door near the bottom beneath the. bead let by a linlt 18, which is articulated to the slide and plate by hinges 18. The. opposite end of the slide is connected to the underside of the trap by a link 19 through joints which are preferably universal in character, they being here shown as consisting of eyes 20, carried by the slide and by a plate 202, secured to the under side of the trap, which eyes engage openings in the ends of the link.

The section 11 of the trap is provided with a contact member, which is here illustrated as a rotatable roll 21, mounted upon a spindle 21, extending across a recess 21". In the closed position of the trap the outer section 11 is held by its weight with the roll resting against an inclined contact-surface 22, which is here shown as a portion of a track 23, extending over the surface of the door in substantially the arc of a circle, so that the roll may coact therewith throughout the movement of the elements, as will be hereinafter described.

Upon the end of the car, lying in the plane of the end of the track 23, is a horizontal track-section 24:, and below this is a shorter section 25, with which the inner end of the trap-section 11 may contact.

Vhcn the 'estibule-door is closed, the parts will occupy the relative positions illustrated in Fig. I of the drawings, the two trap-sections being in horizontal alinement and furnishing a continuous floor to the vestibule. When the door is opened, the pressure of the inclined track-section against the roll causes the latter to ride up it, turning the section 11 about its hinges at an angle to the companion section, this initial movement being permitted without the raising of the companion section by the play existing in the joints between the links, the slide,and the parts they connect; but as the door continues to open the link which is connected with the slide causes said slide to move in its ways and by means of the link 19 raises the section 10 upon its hinges. Then as the inner end of the section 11 approaches the end of the car it strikes against the track 25, which tends to turn it upon its hinges into alinement with the section 10, bringing the roll 21, which has passed over the whole length of the track 23, into cooperation with the track 24, over which it runs. Finally the track 23 contacts with the trap at the adjacent edges of the sections and presses them back into alinement against the end of the car, as is shown in Fig. 5 of the drawings. \Vhen the door is closed, the links, acting through the slide, draw down the trap, the roll operating over the track 23, and as the door attains a position of complete closure the weight of the section carries it down over the incline 22 into a horizontal position, completing the closure. In this manner the opening and closing of the vestibule-door either from the inside or outside automatically actuates the trap, greatly increasing the ease and convenience of operation.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. The combination with a door, of a trap, and means for connecting the door and trap and extending beneath said trap whereby they may be simultaneously operated.

2. The combination with a door, of a trap formed in sections, and means for connecting one section to the door, another section operating in contact with but movable independently of said door.

3. The combination with a door, of a trap formed in sections, means for connecting one section to the door, means for inaugurating movement of another section, and a roll moun ted in the last-named section and cooperating with the door.

at. The combination with a door, of a trap formed in sections, means for connecting one section to the door, means for inaugurating movement of another section. a track fixed to the door, and a roll mounted upon the lastnamed section and contacting with the track.

.5. The combination with a door having an inclined surface, of a trap formed in sections, means for connecting one of the sections to the door, and a contact member carried by another section and coacting with the inclined surface.

6. The combination with a car, of a door and trap movable thereon, a slide mounted upon the car, and links connecting the slide with the door and trap.

7. The combination with a car, of a door, a trap having two sections hinged together, means for connecting the door and trap whereby they may be simultaneously operated, means carried by the door for moving one of the trap-sections relatively to the other, and means carried by the car for restoring the sections to their original relation.

8. The combination with a car, of a door, a trap having two sections hinged together, means for connecting the door with the trap whereby they may be simultaneously operated, means for moving one trap-section with relation to the other, and tracks fixed to the door and car and with which the trap may cooperate.

9. The combination with a car, of a door, a trap having two sections hinged together, means for connecting the door with the trap whereby they may be simultaneously operated, means for moving'one trap-section with relation to the other, a contact member carried by the door, and tracks fixed to the door and car and with which the contact member may cooperate.

in testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
