The brackets and 30 inajy be castings and are riveted or otherwise secured to the under frame ol the car, including the cross tie 30.` Said brackets preferably serve not only as supporting means for the sh .ft 27H27, but provide bearings for the shane 22H22 1which pivotally sup port the swinging doors 2l. Said brackets serve also as strengthening nieansfor the sloping Walls 2O and the sides of the car7 being riveted or o therwise secured to said sloping Walls @Q -20, side Walls l3-l3 and stakes lil-ll as indicated by lthenumeral 3( Then non-round shafts ily-2T are used, in order that they may have proper bearing in the brackets 29 and 3Q, bushings will preferably be provided having circular peripheries lorrotation in circiunt-erential seats Within the bracketsQSl and 30. Bnshings suitable for the purpose are indicated by the numeral 3l in Figure 3. The intermediate brackets Sli-f3() will preti erably have slotted apertures S2-32, the longer ailes of said apertnres 32--82 being vertically arranged. By reason of the slotted construction ol' the brackets 30 30 the inatter of assembly is greatly facilitated, inasmuch as it will frequently be found that the Shafts 2T*27 are not perfectly straight. will he noted from an inspection et Figure 2, the extren'iities of the crosstie 30 are cut away on the under side to allow space tor shafts 27 and the bushings 2:31.. The cross tie 30( will ndinarily take the forni oll a: llangcd beam having a web. `In order to strengthen the cross lie 30 at the extremities thereof, the brackets 30m-3.30 are provided with opstanding tlanges S25-33. which are c-nlcured to the web o'f the cross tie `530".

ln order lo move the il'erinediate doors 2:3--25 troni their open` I lositioxu-i toward closing position, ratchet mechanism is provided for operating the shafts :2l-27. which ratchet mechanism is indicated by the numeral 235. Said ratchet mechanism does not constitute the Vpresent invention and need notV be doseribed in `detail herein. It will be sullicient to state that each of the ratchet mechanisms includes a. ratchet pinion 3G secure l to the cori the responding shaft Q7. l-rlever 3l' is provided Oscillating having an ope ating dog 553. movement of th lever 37 Will cause the dog 38 to engage the ratchet pinion 3G to coinniunicate rotary niotion to the corresponding shaft lllhen the ratchet mechanism 55 is not being used, the lever arin l? is held in inoperative position Within a bracket 30T a locking member il0 being provided :tor this purpose. V'When the ratchet mechanism 35 is inoperative, said ratchet nir-xchanisin will not interfere with the opening ot the intermediate doors 25-25.

ln order to control the opening nimeincnt ol' the interni diate doors 25 5, certain detcnt ratchet mechanism is provided, which detent ratchet mechanism is indicated by the numeral ell. y Une ol' said detent mechanisms is provided l'or each side ol the car, and aldo-v scription ot one will sutlice tor a description ot' both. Each detent ratchet mechanism al includes a detent wheel il?, which wheel l2 is non-rotatably mounted upon its correspondingshattZT. Bushings are provided, having axial apertures conforming to the cross sectional contour of the shalt 27 and halvino' circular peripheries. The peripherics ofi said bushings 43 have bearings Within similarapertures in the bracket or yoke all, which is riveted or otherwise secured to the under frame ol the car. This bracket comprises two substantially parallel legs all and an att-aching member la from Whiclrthese legs entend. The detent wheel 4Q Virrt-h the bushings7 Which may be" used with a non-round shaft, as in the present disclosure, is mounted between the legs lll While the dog fl'is pivot-alb7 mounted upon the ineinber dell. By this construction, the parts are held in proper"operative relation regardless ot the location of the detent mechanism upon the shalt,`independent ot any lined part oit the canor other means for holding theni in this relation. lille present construction thus dillers materially from those shown in applica'nts prior patents hereinbciore refcrred to. y y y y'llic dog lis provided with the axial aperturc lo for the rec aption of a bar by .means ol'` which an oscillating movement may be connnunicatcd to the dog d5. 'lhc dog f; lies witiiin the overall dimensions of the car, so the tit infesents 11o projecting parts. y

lilac-h i" c .vhecl includes a pair ot side Walls Jil-ld which side walls are provided teeth itl-ele located in sl ggerod re latious ip about the periphery oliA d wheels l2. hach olf the teeth dBu-lli is provided with a lace l-Sllyiiig in a plan i ipproximatcly parw allel to the anis ot the shalt Z2?. The opposite laces, bearing the numerals oth-50, are inclii ad relative to the axis of the shalt 27.

ln order to insure the engagement ot' the teeth t8 48 with the extremity ot' the dog le. each of sa id teeth LS is preferably ol such a dimension that it extends beyond the medial plane of the detent Wheel l2? that is to Sayrrelerring to Fig re 7, the teeth 48 should all lll() llll doo; will move said` dog ont ot obstructing relationsl'iip with each tooth 48 in succession,

but will leave it in obstructing relationship` with the Aezitrsiicceedingif tooth 48. VContinued oscillation of the dog 45 will therefore result iii the step-hy-step openingJ of the intermediate doors The teeth 18a-4S are so disposed that when the detcnt wheel isbeing Vrotated hy the ratchet mechanism 35, e.,

in the closingl movement of the corresponding d oor the beveled faces 5'0-50 of the teeth sld-l will engage the end of the oscillating den 15. Inasmnch as the teeth A1B-48 are in sta-d ered relationship with one another, each succeeding; tooth 4S `(in the closingmovement ot the corresponding door 25) will move the end ot' the doglll to one side or the othen.

whereby said vdetent wheel 42 and 'conso qiiently the shalt 2T may be rotated. Reverse movement ot each Vdetent wheel 42 will he stoppeth however, hy reason of the engagement between the dog 45 and the 'laces fl9--494 ot the teeth 48H48, which `faces t9-#419- are in approximately parallel relationship with the airis ot the shaft 2T.,

The tact should be noted that the bracket ell provides a unitary mounting1 for the dog 45 and the detcnt wheel 42, so that the danger ot said doni and detent wheel getting ont of proper relationship with each other is minir mixed. lfloreover,V this proper relationship isV maintained regardless ot the positionof the liracliet eti axially ot the shatt 27. It will be noted that the bracket let .may 'be located at any point within substantially the whole length of sliatt 2T, permitting awide field of selection as to the location of said 'bracket 4l.

The present inventioi-i provides a sturdy structure whichri-idiices the Vamoiint o'fkcyine4 to a minimum. which is simple to assemble and to operatev1 aiidirhich promotes safety.

lhoiigi'h a preferred embodiment of the present in vention has been described in dek tail` it will heelear that many modifications will occur to those `skilled in the art. intended to cover all such modifications that tall within the appended claims.
