BUFFER AND VE STIBULE CONNECTION FOR PASSENGER-CARS.

SPECIFICATION forming part of Letters Patent No. 503,647, dated August 22, 1893.

Application filed May 9, 1893- Serial No. 473,533. (No model.)

.To all tvhom it may concern.-

platform and vestibule, portions of the platform and vestibule being broken away to show the construction and connection of the vertical and horizontal buffers. Fig. 2 is a front perspective of the end of the car and vestibule, the bellows or accordion fold hood being removed, and part of the casing broken away at one angle of the vestibule to show the relation of the rearwardly extending plate or flange of the vertical bufier to the casing and door post of the vestibule. Fig. 3 is a front perspective similar to Fig. 2, the center horizontal buffer having been removed. Fig. 4 is a front perspective similar to Fig. 2, the bellows or accordion rubber hood which closes the space between the end of the car and the upper end of the vertical bulfer being in place. Fig. 5 is an enlarged front view of the rubber or equivalent flexible connection between the two vertical buffer plates at the top, and of Fig. 6 is an inverted view of the rubber or equivalent flexible bellows connection or hood. Fig. 7 is a longitudinal vertical section of the flexible connection between the tops of the vertical buffers and of the bellows or flexible hood on the line x-:r, Fig. 5., showing the relation of said parts to the vertical buffers and the flange or lateral plate thereof. Figs. 8 and 9 are transverse sections of the flanged vertical buffer plates, the latter figure showing how a plate hinged to the bufie'r plate may be substituted for the flange if desired.

Like symbols refer to like parts wherever they occur.

My invention has for its object to provide increased friction surface between the ends of the cars and greater security against telescoping in case of collision and alsoto protion, generally stated, embraces the combination with a railway car, of independent parallel and vertical bulfers adapted to work together or independentlyof each other, whereby the vibration or oscillation of the cars is perfectly controlled or limited to the minimum amount.

A second feature embraces the combination of independent parallel and vertical buffers with each other and with an independent horizontal buffer, so arranged and supported as to be adapted for either conjoint or separate operation.

A third feature of my invention embraces, the construction of the vertical independent bufiers with lateral plates or flanges, to telescope with the door casing so as to exclude drafts, dust, &c.

A fourth feature, embraces, the combination with independent vertical buffer plates of a flexible hood or bellows hood adapted to close the space between the top of the car and the tops of the independent vertical buifer plates.

There are other minor features of invention, and combinations, all as will hereinafter more fully appear.

I will now proceed to describe my invention more fully, so that others skilled in the art to which it appertains may apply the same.

In the drawings, Aindicatesapassenger car platform, and B the usual bumper rail at the endthereof through which passes the stems c c, of the horizontalvbuffer plate 0. The stems c 0, may be rigidly attached to the horizontal bufier plate 0, but are usually pivoted as at c and extendthence back through thebumper rail B, and through the cross bar or equalizer D, between which and the cross bar D' are the springs E, E,--all of which may be of the usual or any approved construction for horizontal bufiers or under some circumstances may be entirely omitted if ahorizontal buffer is not to be used in the combination. When the horizontal buffer plate 0 is used it may be provided with the usual horizontal flange or sill plate. I also prefer to provide a center stem 0 which has itsrear end supported by the springsupported equalizing bar D, in order .to prevent the buifer C from bending if compressed in the center-but said central stem is not an essential feature of the construction.

1, 1, indicate two vertical parallel and independent bufier plates, each of a lengthsub sta ntially equal to the height of the vestibule,

and each supported above and belowbystems.

2, 2, which may be rigidly secured thereto,

or as is preferred pivotally connected therewith, as at 3. These independent buf-*

fers

1, 1,may be actuated by air or weights, without'departing from the spirit of my invention, but are preferably spring supportedasshown, that is to say, theupper stems pass through the fra'm-ingand through brackets-4,

and are encircled by spiral springs 5 which bear on the brackets and against a shoulder or its equivalent on the stem 2. The lower ends of the vertical bufier plates maybe supported in like manner, it desired-and should be if the'vertical butter plates are used without ihtBhOPiZODtitlbllflfGl' plate O,butin case the horizontal buffer plate (3 forms part of the combination I prefer to dispense with in- 1 dependent springs on the lower stems, and to, connect the stems 2*'2, with the equalizing} bar D so that the spring supports E, E, of the horizontal bufier serve for the support of the It will be oblatter, as well as the former. served by examining Fig. l of the drawings,

that the openings in the equalizing barD for the passage of the several stems,a-re of an oval form which permits of the independent as well as the conjoint action of the vertical and the horizontal buffer-plates. It willalso benoted that the cross bar or equalizer D is, so connected with the horizontal buffer stems 0-0, that when any action of the horizontal buffer 0 takes place the

vertical buffers

1, 1,

' are also operated, though thevertical buffers may act separately. The outer faces of the vertical bufier plates may be either flat as: shown in sectional view Fig. 8, or curved, as shown in sectional view Fig. -9, but I'prefer.

to use both-tha.t is to saya flat vertical bu'ffer plate on one car in contact with acurved face buffer plate on the other car (applied alternately), the object being toprovide safety in case of collision. I provide each of the vertical buffer plates 1,

with a rearwardly projecting plate-(or-flange) 5 5 7,whi'ch slides in and out in a recess 7 of the postS-and is covered by thecasing 9, (see Figs.

2 and 3,) so as to form a draft and dustproof connection between the verticalbuifer plate 1 and theplatform. Forconvenience ofconstruction, I prefer to form t-heplate or flange 7 integratwiththe buffer plate 1- (or the wholeof angle iron) but the plate 7 may have a hinge connection with the buffer plate l,'as indicated at 7", Fig. 9, which will be ad- 'vantageous in curving and. permit of a closer A joint as the recess 7 for the reception of the vertical flange, or plate {7 may be of less width than would otherwise be necessary. This construction afiords additional strength to the vertical

lateral bufier plates

1, 1, of great value in case of a collision-and at the same time it produces asmooth iron passage-way between cars and renders it almost impossible for persons to get their hands or arms in- .jured between the butters and door posts of the platform, as now sometimes occurs where rubber is used for filling up the space. When the lateral vertical .platesor flanges are omitted, some flexible material must be substituted therefor'to close up the side spaces between the

vertical buffer plates

1, 1 and the car.

10 indicates a bellows hoodor accordion rubber, (see Figs. 4, 5,6 and 7,) which forms a flexible connection'between the upperends of the vertical buffer plates 1,- 1, and being secured thereto extends down on the outside of the lateral'plates '7 and back to the car roof to which it is also at'tac hed, thus effectuallyclosing the overhead space between the car and vertical bufifer plates by a'flexible connection which, while it securesa water'and dust proof coveredway, in no wise impedes the independent a'ction of the vertical

lateral bufler plates

1, 1.

I wish it also understood 'that'the vertical bufferscan be used in connection with the horizontal buifer by making one of the wellknown connections, either rigid :or flexible. In this case the stems 2 might be dispensed with, so that while the principal feature of my invention is the'independent vertical bulfers Ido not wish to confine myself strictly to that point.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

1. The combination with a railway car, 'of independent lateral vertical bufiers 5 substantially as and for the purposes specified.

2. The combination with a railway car, 'of independent lateral vertical buflers provided with rearwardly extending plates or flanges; sugstantial ly as and for the purposes specifie 3. The combination with a railway car, of independent lateral vertical bufiers, provided with pivoted or hinged rea-rwardlyextending plates; substantiallyas and for the purposes specified.

4. The combination with a railway ca1',-of independent lateral vertical bufiers, provided with rearwardly "extending plates, and a casing and door posts between which said rearwardly extending plates slide; substantially as and for the purposes specified.
