WILLARD E;

' Buffalo, in the county ofErie and State of New York, have invented .a new and useful Improvement in Vestibules for Railway-Car's, of which the following is a specification.

- This invention relates to vestibules for railway-cars. I

The ordinary railway-car vestibuleisprovided at the outer end of the [stationary frame'structure..with an extensible and compressible hood formed by'anopenrectangular frame or face-plate and flexible diaphragms or extensible wallsof other construction, which connect theface-plate to the end of the stationary'partof the vestibule and allow the face-plate t0 move'to- .5 ward and from the end of the "vestibule.-

When the cars are coupled-in a train, the abutting hoodsof the adjacent vestibules are compressed somewhat and the-'face-plates are yieldingly pressed outtoward each other and constantly-held in contactb springs'or pressure means, which allow of t e compression and extension of the hoods due tothe movementsof thecars toward andfrom'each other permitted by the draft devices l The primary object of the invention is to produce very simple, compact, and desirable pressure means for holding the upper parts of the face-plates in contact, soconstructed that the face-plates can be rigidly-secured to the vestibule-buffers and the pressure means located'wholly in the hood outside of'the stationary vestibule. v Y Other objects ofthe invention-are'to improve the pressure means for the face-plates fof car-vestibules in-the respects hereinafter specified, and set forth in the claims;

' In theaccompanying drawings, -consisting of two sheets, Figure 1 is a longitudinal sectional elevation of a portion of the stationary structure and extensible' hood of a -car' vestibule embodying the-invention; Fig. 2 is a rearv elevation of the face-plate, partly in section in line 22, Fig. 3, omitting the dia-- phragmsl Fig. 3 is a horizontal sectional plan of the vestibule'in line '3 3, Fig. 1. Fig. 4 is a fragmentary elevation, partly in section, of the end of thevestibule and pressure devices for-the face-plate. Fig. 51s a sectional elevation, on an enlarged scale, of one of thezpr'essure devices for the face-plate.

Like letters of reference refer tolike parts in'the'several figures. A represents the outrrpassage-way frame orouter end of'a car-vestibule; B the mov able face-plate or'frame which is similar in shape to the'outer end of the'vestibule and is connectedat its sides and-top to the endof the vestibule by the flexible or extensible diaphragms or'walls forming the top and sides 'of'the extensible and" compressible hood. These parts may be of any usual or suitable construction. 1

In the construction shown in the drawings the metal face-plate is reinforced by" upright T'-bars riveted to the sides thereof, and-the walls of the hood are preferably formed b inner and outer diaphragms 'C' C, but suc construction is not an essential of'the inven tion.

The face-plate B is riveted or otherwise rigidl attached at its lower end to the vestibuleuffer D, which is pressed yieldingl {out in front of'the end=sill (tor the vestibu e by the usualbufier-sp'rings. --(Not shown.) The buffers'of cars coupled together are held in contact by their springs irrespective-of the movements ofthecars toward and from each other, and so'hold the lower portions ofthe face-plates of adjoining hoods in-oontact and the buffers are usuall capable of pivo tingg'or Swinging horizontal y somewhat, so -that they and the lower ends ofthe face pl'ates are held flat against each other throngh git their width when the cars erre -rounding curves. Asthe face-plates are of considerf links swing on their pivotal conneotionswith the end of'the vestibule in; the movements of the face-plate toward and-from-the latter,- 1 and as the face-plate 'isii igidly attached to the vestibule-buffer, andso'held from vertical movement, .one end of each'liri'k hasiaisl-id 'ing connection with thei partitouwhich itiis clined position, and 'therebypress the faceplate outwardlyfrom the end of the vestibule. Preferably the links are pivoted at their lower ends to the end of the vestibule and their upper ends are'pivoted to slides F, which are movable vertically on the rear sideof the faceplate, and the upward movement of the slides is opposed by suitable springs G. The construction of the links, slides, and pressure devices may be varied. In the construction shownin the drawings the lower end of each link is. rovided' with a cross-head or pivot e,

which ears in the seat of a fulcrum-box e,

secured on the end of the vestibule. The fulcrum-box has a removable ..cap plate, which is slotted vertically to allow of the movements of the link and to enable the link to be placed in and removed from its seat,

and the cap-plate is provided at opposite sides of its slot with projecting lugs 6 between which the link is guided and is held from lateral deflection. Each slide F, to which the upper endof the link is pivoted, has a hollow cylindrical upper portion, which is confined and guided in a hollow cylindrical pocket f, secured to the rear side of the faceplate, .and a depending' slotted extension f Aheaded stud passing through the'slot of said extension and secured to the face-plate, assists in guiding the slide and prevents the detachment thereof from the faceplate. An-

antifriction-rollerf .surroundsthe stud f 2 in the slot, to reduce the friction between the slide and the stud. The link E can be pivoted to the slide F by a pin f 4 or in anyother suitable manner. The coil-springs G, which oppose the upward movement of the slides F, are'in'closed and protected in the hollow ortions of the slides and the guide-poo ets therefor.

When the face-plates are forced rearwardly or, toward the ends of the vestibules by the bumping of the cars, the links E swing rearwardly with the face-plates, and as their upper ends move upwardly in the arcs of circles the slides F, connected to the links, are moved upwardly ,on the face-plates and compress the springs G in the spring-pockets. The pressure of the sprin s on the slides constantly tends to force t e latterdownwardly, and such'downward movement of the slides forces the links outwardly and through them presses the upper portion of the face-plate outwardly. The vertical movement of the slides is slight and short springs can be employed, As the springs are arranged vertically,.they occupy the least possible horizontal space and will allow the maximum movement of the face-plate toward theend of the vestibule. If the springs'were arranged horizontally, they would have to be several times the length of the s rings shown to obtain an equal movement of the face-plate and would consequently have to be let into the vestibule structure, thereby making it necessary to out into thevestibule' to apply the pressure devices and greatly increasing the cost of application of the hood to the vestibule. The links are independently movable and enable the upper part of the face-plate to assume an oblique position, so that the upper as well as the lower part of the face-plate will maintain a proper contact from side to side when the cars are rounding curves.

In a hood such as shown, having inner and outer diaphragms or flexible walls, the pressure devices are preferably located between upright side portions of the two diaphragms.

Some means, such as a chain H, attached at opposite ends to the upper part of the end of the vestibule and passing around a sheave h, secured to the upper part of the face-plate B, are employed for hmiting the outward movement of the face. Any other suitable stop device could be used.

I claim as my invention 1. The combination with a car-vestibule, of an extensible hood therefor, and means for extending said hood comprising a swingin link which connects the outer portion of sai hood to the vestibule and is pivoted at one end to one of said parts and has a sliding connection at the other end with the other part, and means exerting force on said link in a vertical direction to swing the link away from the part to which it is pivoted, substantially as set forth.

2. The combination with a car-vestibule, of a face-plate which isconnected to the vestibule by an extensible wall and is movable toward and from the vestibule, and means for pressing said face-plate outwardly away from the vestibule, comprising links each pivoted at one end to said vestibule and having sliding and pivotal connection at the other end with said face-plate, and means exerting force on said links in a vertical direction to swing them away from the vestibule, substantially as set forth.

3. The combination with a car-vestibule, of a face-plate which is connected to the vestibule by an extensible wall and is movable toward and from the vestibule, and means for pressing said face-plate outwardly away from the vestibule, comprising links pivoted at their lower ends to the sides of the vestibule and having pivotal and sliding connections at their upper ends with the upper side portions of said face-plate, and springs carried .toward and from the vestibule but is held from vertical movement, and means for pressing said face-plate outwardly away from the vestibule, comprising links pivoted at one end to the vestibule, slides pivoted to the other ends of said links, hollow springpockets on said face-plate in which said movable horizontally toward and from the I vestibule, and means for pressing said faceplate outwardly away from the vestibule, comprlsing links pivoted at opposite ends to the side portions of said face-plate and vesti- 2o bule and also having sliding connections with said face-plate, and means for yieldingly resisting the movement of said links toward the vestibule, substantially as set forth.
