To all whom t may concern:

Be it known that we,l CHARLES B. YOUNG and GARTH G.GILP1N, citizens of the United States, residing at Aurora, in the county of Kane and State of Illinois, and Riverslde, in the county of Cook and State of Illinois, respectively, have invented a certain new and useful Improvement in Vestibule-Diaphragms for Railway-Cars, o f which the following is a full, clear, concise, and exact description, reference being had tothe accompanying drawings, forming a part of this specification. I

OurV invention relates to improvements in vestibule diaphragms for railway cars.

One of the main objections to the present form of vestibuleA diaphragms used on raili way cars lies in the fact that the same are not fireproof, since the same are generally made of canvas or like inflammable ma'- beviel. and often get on vfire caused by sparks from the locomotive. These fires sometimes '.spread to the car, and. in any event, require kconsiderable time and labor to extinguish the same to prevent spreading.

One of the objects of our invention 1s, to

cars which is absolutely fireproof.

fproyide a flexible diaphragm for railway Other objects of our invention are, to pro- "ide a vestibule diaphragm of durable'construction, and yet'which may be manufactured at relatively small expense.

:in Fig. 1.

'2 scoped, Fig. 6 is a sectional view of the,A

upper portion of a diaphragm and platestoy whichit is attached, showing another,form of our improvements. Figs. 7 andrj8 are improvements in connection therewith. Fig.

.'2 is a side elevation of the structure shown Fig. 3 is an enlarged Vertical sectional view taken substantially on line 3-8'of Fig. 1, parts being broken away to prevent crowding of the drawing. Fig. 4 is a horizontal sectional view taken substantially on line 4-4 of Fig. 1, upon an enlarged scale.

Fig. 5 is a vertical sectional view taken through the top of the vestibule diaphragm, and showing the positionof the parts when the Same are compressed or televiews similar to Fig.` 6, showing other forms of our improvements. I

Referring now to Figs. A1 to 5 inclusive, 10 denotes the vestibule diaphragm face plate, which is secured to the buffer plate 11 at the bottom thereof in vthe Ausual manner. Mountedon the buffer plate 11 is the foot plate 12, which slidesunder the vestibule door plate 13. The buffer plate 11 is normally pressed outwardly by the lusual buffer mechanism l(not shown) by means of the buffer stems 14. 15 denotes the end plate secured to the end of the vestibule, said plate having mounted thereon brackets 16--16, inv which slidably engagethe ends of a plurality of bowed springs 17, which pass 'through and are secured to another bracket V-18 firmly attached tothe upper cross member of the face platevv 10. As will be understood, the springs 17 normally tend to press the upper portion of the face plate and the diaphragm carried thereby, outwardly in the usual manner.

""Our improved diaphragm, as shown in Figs. 1 to 5 inclusive, comprises a plurality of relatively slidably mounted, telescoped sheet metal members, of which those refer- 15 of the vestibule; 21 is secured to the diaphragm face plate 10; and 22 and 23 are secured to each other, and slidably mounted between the members 19 and 20, as shown most clearly in Figs. 3 and 4. As will be understood, each of the members 1`9`tov23, inclusive, is substantially of in- 'vc'rted U-shape, that is, each member has thei'membervlf) is secured to the plate 15 by Y' rivets or other suitable, means, and the flange 26 of the member 21 is also suitably secured to rthe face vplate 10` by ,rivets or bolts, asshown. yThe flange 27 on the opposite ond of the member 19 on which the flange 25 is located is turned inwardly and .is adapted to limit the outward movement off" the member 22 by engagement/with the flange ,28,of the latter. Similarly, the

flange 29 fonftlief/lner edge of the member 7 enced 19 and 20 are secured to the end plate substantially ,to the member previously dewith the 30`onrthe outer edgeof the meiiibei' 22, to thereby pull the "latter outwardly, andalso to .limit the out?A "wardiinovement of the sheet'iiietal ineniber 5 21.

l rovided with anvinturiied flange 31,.which fis secured toftlieI .end 'plate 15` by any suit- Vable'means, and the outer edge of the niem- 1 ber 20 is preferably flared 'asi'ndica'ted at 32. The member 23 is providedvwith an outwardly extending lflange 33, which is `se,- f curedto the flange 28"of' the member 22 by any. suitable means such, for instance, as spot welding; and `tlie outer edge of' the i A member 23 is also flared as indicated lat 34.

'As will bciinilerstood, all the flanges on l *the edges of the members '19 to 23, inclul sive, extend along the sides, corners and tops thereof. l 'f l From the preceding description, it is thought that the operation will beevident,

it being apparent that the member 21 tele.-v

vscopes withintlie members 22 and 23, and the latter in turn telescopes within the 25. members 19 and I29.' All these sheet metal members are Iof relatively light material'- I and flexible, 'thereby adapting the diaphragm :to yieldlaterally and vertically to accomaroused. Furthermore,the parts are so designed that all the members of the dia` phragin `proper are `in 'yieldingI fi'ic'tionall .engagement with each' other, which is an vimportant consideration *in preventing rat- :ftling of lthe parts.` The parts are of simple construction, the saine may be cheaply inaniifactui'ed, and provide any absolutely firei proof vestibule. In `addition 'to the fore,- 'going, it is apparent that the inner surfaces :ofA the diaphragm proper are substantially plaited nloiiuofdiaphragm now commonly i used, *since `with the latter construction `therefare numerous recesses or grooves in whiclra passengerpassingthrough the vestibulcgmay` get his hands caughtl upon sudi w den compression of' the diaphragm.

l ,'Referring now to Fig. 6', the form shown L -20, therein comprises members 119, 120, 122,

and 121, of which those referenced 119 and 120;' are suitably secured to the -end plate of -the vestibule, and the member 121 is bolted or otherwise secured to the diaphragm face `plate 1-10. The member 120 corresponds i scribed and referenced 20, buttlie member y g1 L9 instead of being' provided with a right- ,i

= angledV flange, is provided with' a hook 127 69` with4 which is adapted to cooperate and engage an oppositely turnedhook 1128 ony the inner .edge of the member 122. The outer ,cdgeof ythe member 122 is provided'with av curved .hook flangei130. `and is adapted to engage with an oppositcly turned curved The' 1neinberf20` on .its inner .edge is `.=\'s` Iwill beunderstimd, the intermediate inoilate Aitself to all the movements incident tov the operation of tliecars on whichy they .l flat, which is an improvement `over the "fla-'nge 129 :on the-member The diapliragni face plate is mounted in the usual manner, and is pressed outwardly. `at the top b v ineansof leaf springs 117.

- ,Ingt'he arrangement Just described, it will be seen that the intermediate metallic member is formed of a singleipiecepand tele'- scopes between the members 119 and 120.

member 122 will be prerented` frombecom- 7i ing` displaced laterally onv account'of the fact,- that any tendency for said member to 'move to one side will be resisted by the en- I gagement of the leg thereof on 'thewopposite side., with the adjacent legs of the members 8l "119, 120 and 121. `The saine result occurs when the intermediate member 122 tends to niov upwardly or downwardly relative] to the other members of the diaphragm wit which it coperates. i

In Fig. 7, the diapli'agniishwn therein comprises metallic plates or strips 219, 220, 222 and 221. Asy shown, the members 219 and 220 are secured by rivets brother suit*- able` means to the 'vestibule end'` plate 215,

the member 219 being provided with a rightangled flange 225, the member 220 with., a. similar flange 231.' Pinand yslotg'connepctions are' provided betweenthe members 222 and 219,y one Iof which is indicated at 235, 9|,

it being'under'stood that these pin'and slot connections will be dis osed at suitable distances apartalong eaci legend vacross the top of the diapliiagin`menibersfthl slots being foi-ined inthe plate 219 and 'the pin attached to the lmember 222, so that the outward movement of the latter will' be limited in av well known mianneri yThe outer edge of the sheet metal plate 222 is provided with y an in-turned"curved flange 230'V adapted to "metal members, the saine being referenced, respectively, 319, 322 and 321, the latter being attached to the face plate 320 by bolts, as shown'. The member 319 is secured to the end plate `of the vestibule in the same man lll .ner that thepreviously described members 19, 119 and 219 are secured. The interme-v diate member 322 is substantially Z-shaped in cross section throughout its length, the -flange 32S on thevinner edge'thereof being vturned inwardly, and the flange 330 on the outer edge thereof being extended 'outwardly. A `plurality of pin'iand slot connections and 331iv are proyidcd between the members 321 and|322` - anil 322 and 319,

respectively, said pin and :slot connections being disposed throughout the length of the' members as above described in connection with the structure shown ,in Fig.v 7.

When the diaphragm shown in Fig. 8 is collapsed, the inner ledge of the plate 321 .will engage the flange 328, and Ymove the intermediate plate-inwardly, and likewise `the outer edge ofthe plate 319 will engage the flange 330 to slide the latter over the plate 321.
