The present improvements refercmore esi pecially to the means for yieldin-gly and ad- 30 justably supporting` these metal plates v)2in a Vhorizontal position sogthat they mayhuo' 1,' above the couplingdevices, at the's'ame 35 time keeping the meetingedgesofthe plates 2 in close contact with each other while the Acars arerunning and thus prevent any substantial separation at any time' of said'edges l `when the cars areintercoupled, which separa- Y l tion` might sometimes be caused by oscillation of theiparts andiineven strain vonthe lier 3, the latter member 3 `beingsecuredin a suitable manner to the underside Vof the corresponding plate 2'; and #heretical Side 1- ,100

beingvsecured toa parallel plate or'bar mem- Y ber 8, which belongs to the lower end of the vestibule frame, it being noted that the outer edge of plate 2 rests upon or is firmly connected to the top edge of said plate 8,y as seen in Figures 2 and 3. Thus each car platform has the same carrying means for its movable plate 2,' saidmeans -consisting ofthe angle beam 4, 3, and the vestibule frame plate 8,-

which are united together and'to the plate 2V into a single unit after the manner described Y for in some equivalent way. And thus there are two suchV units in a closely contiguous relation when two cars are` coupled together,

causing an arrangement such that the lower sections-8 ofthe two vestibule framesare' 1n vclose contact with each other at the same time thatthe r-emaining upright frontfaces of said lframes are closely associated as seen in F igure Q i l, .i v v i v 1 These vertical vestibuleframes are only Y partiallyfshownV so farvas may be necessary,

but they-appear-in elevationin Figure 3 and jinedgeview in Figure 2; So :far as my present invention 1s concerned 1t Yls-enough to 1l- 'lustrate the par-ts I `have shown,'and.to say Vthat thetwo frames, one on each platform,

Varerectangular and closely adjacent to each other when the cars are coupled together. Each frame {has the-vertical Hat side ' strips 7, 7 ,connected at the top by theintegral cross stripe-7a, and at the bottom ends by the horizontal cross stripY or plate 8. f These latter plates4 8 areriveted orsecured to the angle beams 4-by rivets or bolts 17. Hence the lower ends of these vertical-frames are vunited Y movement7 and since they are located on each with the units above spoken of so as' tobe invclu'dedftogetherV with the/'platform plates 2 and the angle beams 4, 3.; so that the uprightv 7A and therectan'gular frames of which they 'are apart, the plates 2 and thel angle beam are so joined `together as'to have a unitary car lplatformv it will followthat as Vthe vestibules'oftwo cars are brought into closeassociation the plates 2 will have their trans- `Vverse'edges-'brought into contact, and'during Y Vthe fluctuations and vibrations of the Vvarious i GQ parts the platesr 2 will move more or lessY towards' or away-from-each other.l or sidewise carrying the various connected elements with them. v

` 7 vIt be remarked that these frames havl-ing the members and 8 Vare obviously only the outer frames of the vestibules. They are connected usuallybyfaccordion or bellowslikefeXpansion partsV withV similar upright frames 32, which are the main stationary uprights- "of'the vestibule construction, but the `details of these expansion members ,are not shown, except in dotted lines, as they-are not necessary to*the"presentexplanation.L

The, chiefy problem which my invention v '.seeksftosolveftherefore isV the 14provision of f 'jv "ans vfor keeping the plates V2, 2, closely up against the underside of the platform plates V1 during all the oscillations to which said plates 2 are subject .asthe car platforms vif brate andjar and strainv underthe load carrled or the rapid or uneven lspeed-and irregufects. `Therefore to solve thefproblemisatisfactorily I arrange under these plates 2 Vre-v siliently-acti'ngA means constructed and ap-v plied in the following manner:

In a bearing below the car platform, whichv Y bearing may be formed as partvof the main frame, or the transverse beam 25 isV .a longi-4 tudinal rod or bar 5- adapted toy travel endwise, its forward end being Vconnected to one of the angle beams which :carry the Vplates 2 and associated parts so as to particularly control the position of said plate 2. i The krear vend of bar 5Vis :yieldingly connected to the Y y main car frame, as 27 ,by nieanseof asprin 6 which surrounds the inner end thereof an is tensionedbetween the angle piece 28riveted'to yframe 27 and the aforesaid bearing for lthis bar 5; the'end of thebar 5 that passes Vthrough .part 28 being screw threaded. yat 30 and provided with a nut/29.. so asv to tighten or loosen the strain and regulatefits power. There is a similar arrangement of a bar '5 on each car bufferusothat when the vestibule frames' meet each other in carl coupling .and the like,the plates 2 may be adjustable. or movable back-,and forth as much as may be necessary under the yielding controll of the spring connections` as described.` There will usually, be two bars 5in each carbuffer, one oneach side,rso .as vto balance the str-ainand 7e i larities of the rails as well asroadbed de- I action on the plate 2, that is toV say eac-hi plate Y I 2 will-be vunder the control ofV two o f the spring-provided bars. i y l l Further, 'the end. ofeach bar v5 nearest'the angle beam 4, 3,' is formed with'an eye at 11 rthat receives a vertical pin whoseuplper end 12'ent'ersa round hole? in the angle beam flange 3 and bears against plate 2, there being a springr 13 between the eye 11 and theV iange 3; while the lower end 14 ofthe pin enters an `opening` in a short' angle plate 9' that is riveted to the angle beamv member 4 near its lower edge, as shown in Figure 5,:a

therefore a connecti'onfis made between the unit that includes the plate 2 and the control bar 5; and valso the plate 2 and- .associated vpartsare carriedresiliently on the bar 5 "so as to enable said plate to be kept in close 'con-l tact with the platform plate l, and also to enable the other parts whichare associated in a unitary combination with the plate 2 to be kept in Vtheir proper relative -position during the expansion and contractiony ofthe bel- Y ment just described will quickly restore its contact, noiselessly and without-shock or undue vibration. Y

Since there are duplicate spring mechanisms between each plate 2, or any number ofA such mechanisms corresponding to the number of the control bars 5 it will be evident that the even action of the bader mechanism on bothv of the abutting platforms is regulated and insured, and the bridge consisting of the two plates 2 between the two car platforms is preserved at a proper level and is capable.

' trally` a'sm'all wearing platel against which at all times to allow easy passage bythe passengers from one carto the other under all j conditions of speed and vibratory movements the platforms being therefore as safe and as protective for the passengers as the interior of the car itself. Y

ln order that the contact between the front frames of the vestibule structures at the meeting ends of two carsmay be properlymaintained and easily made when the ycars are inteicoupled and thatthis may be without shock or ,clash asrthe cars rock .andthe couplings oscillate and adjust themselves, l find,

it convenient to provide the meeting faces Y of the upright sides 7 ofthese frames, as well strip 7 of the frame on the other car, asl

" shown clearly in Figure 2. The ball A is kept in place by a series of small balls 23 surrounding it and carried in a raceway 22 that is enclosed in a box 2l, whose flangesv 24 are i screwed or riveted tothe plate 7 on the rear side .of the same, or the side .opposite to that on which the ball A projects to meet the adjoining strip 7. Each of these vertical frames having members 7 and 8, which meet on the f two cars, have two of the balls A, one in each member 7, and with two such ball bearings in each connection 8, but the two balls in one frame are staggered in their relation to each' other,

This staggered position of the balls in the two frames causes the balls in one frame to ries two or more such ball bearings whichV project through the vframe and roll upon the "frame provided Vwith a number Vof ball .loearingsl andV the other frame --with #noi such ball bearings, for f,it"prevents the possibility7 of the meeting oftwovestibules havingnofloall bearings, ortwo vestibulesboth having ball beaiiitgs in thesam'epo'sition which wouldiV causeafclashingof'aetion.-j inthe case oftheV connections f8, as seen in Figures 2 and 5, the

VIt willfurther bevnoted that the movement of the bars 5 is assisted l by ball bearings 26 arranged on the castings v that carry the bars 5 as already explained.
