To all whom t may concern:

Be it known that l, DON M. MCGILL, a citizen of the United States, residing at Chicago, inthe county of Cook and State of Illinois, have invented a new and useful improvement in Passenger-Cars, of which the following is a specification'.

My invention relates more particularly to passenger cars, the platforms of which are providedwith vestibule doors which are adapted to be opened and closed to permit passengers to board the cars and leave the same, under the control of an operator, usually the conductor, and provided with barrier means for dividing the car platforms into entrance and exit ways, and adjacent to which the conductor stands, these barrier means being shiftable from a position in which they define the entrance and exit ways on the platform when the fares are collected at this platform, to a position in which they serve to partially encircle the moterman, thereby forming a barrier between him and the passengers, when the motorman is stationed at this end of the car and the fares are collected at the other end.

My primary object is to provide in a car equipped with a shiftable barrier as above stated, vestibule doors with means operated by the conductor for controlling themso disposed and arranged as to permit the doors, and also the steps, if the latter are of the type now commonly employed vand simultaneously operative with the doors to cause the steps to be folded out of position when the doors are closed and to be extended into operative position when the doors are opened, to be readily controlled by the conductor, who stands adjacent to the barrier, without obstructing either of the passage ways on the platform and which will permit the conductor to quickly close the doors following the entrance or eXit of a passenger.

A further object is to provide a'construction of controlling means above referred to', whereby the platform of the car when the barrier is in a position in which it partially encircles the motorman, will'befree of obstruction to the passengers on the platform.

Referring to the accompanying draw ings-@Figure t is a pian view, somewhat in the nature of a diagram, of a portion of one of the similar ends of an electric car provided with mechanism in accordance with my invention, the car proper including the doors, steps and platform, being shown in dotted lines, with the barrier shown by full lines in positionv for defining the entrance and exit ways, and in dotted lines in position for partially encircling the motorman. F ig. 2 is ay view in sectional elevation taken at the line 2 on Fig. l and viewed in the direction of the arrow. Fig. 8 is a similar view taken at the line 3 on Fig. 1 and viewed in the direction of the arrow. 4 is an enlargedview in vertical sectional elevation of the upper portion of the mechanism shown in'Fig. 3, for controlling the operation of the vestibuledoors and the coperating steps, this portion of the mechanism being carried by the barrier means and releasably engaging Vwith other cooperating parts of this mechanism arranged in fixed position relative to the Hoor of the car. Fig. 5 is a similar view of the lower part of the mechanism illustrated in Fig. 3, this view sho-wing the lower end of the removable portion of said mechanism and the manner of its coperation with the other stationary portion of this mechanism. Fig. 6 is a broken view in vertical elevation of the lower end ofl the removable portion of the door and step operating mechanism. Fig. 7 is a view in vertical sectional' elevation of the upper end portion of the relatively stationary portion of the said mechanism, showing the position it occupies'relative to the platform of the car. Fig. 8 is a bottom plan view ofthe structure shownin Fig. 6. Fig. 9 is a plan view ofthe structure shown in Fig. 7. Fig. 10 is a broken view in elevation of the intersecting portions of the barrier means and door and Vstep operating mechanism; and Fig. ll, a view in elevation of the portion ofthe mechanism of Fig 6, showing it in the position it occupies relative to the platform 'when the barrier is lpositioned about the'motorman.

' For the purpose of illustrating my inven-A tion, I have chosen to illustrate it as applied to 'an electric car, the end portions of which are constructed in accordance with well-known practice.- The cars of the type shown are provided at opposite ends, which are of similar construction, with platforms 12, one only of which is shown, with two door-ways at each end of the car opening on to the platform, these door-ways being separated by a partition 13 arranged substantially midway across the end of the car. VIn the drawings (Fig. 1) one of the door-ways, which in the construction illustrated would be the exit door-way is represented at 14, the other door-way at this end of the car and which would be on the other side of the partition 13 and constitutes the entrance door-way, being omitted. Coperating with the-platform 12 is a barrierdevice 15 in the form of a railing which is curved to present two sections which extend substantially at right-angles to each other, the barrier in the full line position represented in Fig. 1 extending at one end adjacent to the partition 13 at the side of the latter yfarthest re moved fromfthe door-way 13 and at its other end adjacent to the edge of the platform at the side of the car, thereby dividing the platform into entrance' and exit ways which lead to the doors of the car here-inbefore' referred to. The barrier'means 15, when this end of the car is occupied by the motorman, and the conductor is stationed on the platform at the other end of the car, is shifted by the operator from the position represented in full lines in Fig. 1 to the position represented by dotted lines in Fig. 1 to operate as a shield for the motorman, this feature of providing for the transfer of the barrier means 15 from one position to the other as'stated, being in accordance with common practice.v

The'platform 12 at the edge thereof adiacent tothe point at which the barrier means l'termin'ate is provided with folding doors and with folding steps, this feature of cars of this type serving'to permit of the maintaining of the clcsing of the'platform of the car, except a-sthe doors'are required to be opened to permit passengers to board and leave the car. `the oppositeside'of `the platf-ormbeing closed. In the particular type of car illustrated. the door-way to he 'controlled bv the foldingdoors above referred to. is a single'opening. and two doors are provided` one of them being formed of sections 16 and 17 hinged 'together as represented at 1S and secured at the section 16 to a verticallv disposed shaft 19 iournaled anv suitable manner in the bulkhead of the car. and the -other of the said doors being formed of sections 2O and 21 hingedly connected together as indicated at 22 and secrred at the section 21 toa vertically disposed rotatable shaft'23 suitably journaled at ythejrear' end of the platform. 'the sections 17 andf20 being guided in 'anv suitable inanner.fas`byfpins24 secured'to the'upper edge portions of the sections @17 'an-th4 20 and-run rier l15 fromthe full line ning in a track 25, secured to the car at the upper side of the door-opening in accordance with common practice, whereby when the shafts 19 and 23 are rotated, the cooperating door sections 16 and 17, and 20 and Y21, respectively, are folded into the folded positions represented by dotted lines inl Fig, 1 to permit passengers to board, or alight from, the car, or into extended position wherein they fill the door opening at which they are located. The platform 12 is provided with two steps 26 and 27 arranged opposite the two vestibule folding doors just described, these steps being pivotally supported on the car structure, as indicated at 28, in accordance with common practice, whereby they may be moved into and out of step-forming position.

The above referred to doors at the side of the platform and the steps 26 and 27 are adapted to be independently operated by the conductor, who stands at the barrier 15, by mechanism connected with these doors and steps and operated by handles provided on the barrier 15 within easy reach of the conductor located at the curved portion of the latter, at which portion a seat 28 for the conductor is provided on the barrier. ln accordance with my invention, the mechanism for operating these doors and steps is provided'in sections of such form that they are separable at, or below, the level of the platform 12, whereby upon moving the barposition represented in Fig. 1 to the dotted line position represented in this figure, the platform is relieved of any obstacle to the free movement of the passengers over the platform, a description of a desirable form of operating mechanism for the purpose stated being as follows: rThe shafts 19 and 23 are provided with arms 29 and 30, respectively. these arms being pivotallv connected as indicated at 31 and 32 with links 33 and 311. the link 33 being pivotally connected as indicated at 35 with an' arm 3G rigidly connected with a sleeve member 37. The link 34 is pivotally connected as indicated at 38 with an arm 39 rigidly connected with the sleeve-member l0. surrounding the sleeve-member 37. the portions of the mechanism iust described beine' located below the platform 12. The sleeve-members 37 and 40 are disposed verticallv and are supported to be independently rotated. -`the sleeve member 37 beinfr supported at its lower end at a ball-bearing 41 an a stationary plate 42 and passing through a plate 446. with ball-hearinffs 48. confined between the plate 46 and the sleeve member 37.

The plate [42 is secured bv bolts 43 against the bottom of a block 47 which bears against the plate 46 positioned against the bottoni of areastin'g' 44, the bolts 43 passing through these plates; block and .casting and. securing them rigidly together. The casting 44 is hollow and is secured at its upper end in an opening 45 in the platform 12 (Fig. 5). The sleeve member 40 is rotatably supported at ball-bearings 49 and 50, the bearings 49 being interposed between the lower end of this sleeve and the plate 46, and the' ballbearing 50 being interposed between the casting 44 and said sleeve a slight distance above the lower end of the latter. The sleeve members 37 and 40 doI not extend above the top of the platform 12, as shown in Fig. 7, and to adapt them to be independently rotated, their upper ends are notched as represented at 51 and 52, respectively.

It will be understood from the foregoing that the sleeve member 37 vcontrols the doorsections 16 and 17, and the sleeve-section 49 controls the door- sections 20 and 21, the rotation of these sleeves operating to move the door-sections to extended position in which the door-way at the side of the platform is closed, or to folded position in which the door-wav is opened, depending upon the directicn in which these sleeves are rotated.

ln the construction illustrated, the steps 26 and Q7 are operated simultaneouslv with the doors just referred to, bv actuating the sleeve members. this being accomplished by `providing the following mechanisms: The

step Q6 is provided at its inner edge with an arm 53 pivotally connected as indicated at 54 to a link 55, the inner end of which is pivotallv connected as indicated at 56 to a link 57 pivotallv connected at 53 to a bracket 59, the link 57 being also pivotally connected at 56 with a link 60 pivotallv connected with the link 33. The step Q7 is connected with a link 61 in the manner described of the step 26, the inner end of this link being pivotally connected as indicated at 62 to one end of a lever 63 pivoted between its ends as indicated at 64 on a depending boss 65 secured to the underside of the car platform, the opposite end of this lever being pivotally connected, as indicated at 66, to a link 67, pivotallv connected, as indicated at 68, to the link 34.

It will be understood from the foregoing that shifting of the links 33 and 34 to operate the folding doors as described will simultaneously operate the steps, causing them to be swung to step-forming position when the doors are opened, and out of stepforming position upon closing the doors.

The means for actuating the sleeves 37 and 40 are carried by the barrier means 15 and are so constructed and arranged that they may be assembled with these sleeves upon positioning the barrier 15 for defining the entranceand exit ways, a description of these means in the form` in which I prefer to provide them being asfollows: Secured in the barrier 15 toy extend substantially to the upper surface of the platform 12 when the barrier is in the full line position represented in Fig. 1, is a tube 69, this tube containing two independently rotatable tubes and 71, one within the other. rThe tube 70 is journaled on the stationary tube 69 at ball-bearings 72 and the tube 71 is j ournaled at its upper end on the tube 70, at ball-bearings 73, ball-bearings 74 being confined between the lower end of the tube 70 and the stationary tube 69, and ballbearings 75 between the lower end of the tube 71 and the lower end of the tube 70, whereby the tubes 70 and 71 are supported in position and in a manner to be independently rotated. The. lower end of the sleeve 70, which is adapted to enter the opening in the upper end of the casting 44, is provided with two diametrically opposed lugs 76, adapted to be inserted into the slot 52 in the sleeve 40; and the lower end of the tube 71 is provided with a head 77 having a depending lug or tooth 78, adapted to enter the notches 51 in the upper end of the sleeve 37. The sleeve 70 carries a removable handle 79, splined thereon as indicated at 30, and the sleeve 71 has a barsection 81 rigidly secured in its upper end, to which a removable handle 32 is splined as indicated at 83, it being understood from the foregoing description that the handle devices 79 and S2 are independently operable and serve, respectively, as means for opening and closing the two sets of doors at the side of the platform and simultaneously operating the coperating steps.

Under certain conditions it is desirable that the handle devices 79 and 32 be connected together so that the operator may actuate both sets of doors by grasping one only of these handles, and as suitable means for this purpose, 1 provide a dog 84, pivotallv mounted, as indicated at 35, on lugs 36, depending from the handle 79. rlfhe heavy, toothed, end of the dog 34 opposes an opening 87 in the handle 79 and, by press ing down on a shiftable pin 8S slidably mounted in the handle grip 39 on the handle 79 and coperating with the other end of the dog 34, may be'rocked into a notch 90 in the underside of the handle 32, thus locking these handles together for simultaneous movement.

It may here be explained of the barrier means 15, that. the end thereof, which opposes `the partition 13, is of the usual construction and is adapted to be releasably connected with the partition to render the barrier stable. The opposite end of the barrier is formed with a section 15EL pivotally connected as indicated at 15b with the main portion of the barrier and is adapted to releasably interlock with a socket member 15c provided on 'al stanchion 91 stationary on the' platform in accordance with common practice.

Ni h the parte in the position shown in ' sleeves 70 and 71 ao'aipst rotation.

full lines inFig. l, the conductor positioned Withinthe barrier 15 may readily open and close the doors and operate the coperating steps at the side of the platform independently of each other, Without in any Way obstructing, or being obstructed by, passengers entering or leaving the car.

As the members 69` 70 and 71 have a fixed relation to the barrier 15, the transfer of the barrier means 15 from the full line position represented in Fig', 1 to the dotted line position. represented in this figure, to form a barrier between the motorman and the passengers on the platform, will cause the sleeve members 70 and 71 to'be Withdrawn from engagement with the sleeve members 37 and 410, thus rendering` the cen` ter of the platform clear of any obstruction, as the sleeve members 37 and 40 do not eX- tend above the upper surface of the platform. rilhe handles 79 and S2 beine,` remov` able, the conductor Will accordingly detach them from the `sleeves 70 and .71 and position them for use on the door-operating mechanism provided at the other end of the ca thusv necessitating the provision of but one pair of handles for each car.

The platform 12 at a point coincident with the position occupiedv by the sleeve members 70 and .7 1. when the barrier 15 occupies the dotted line position represented in Fig. 1. contains the opening 92 provided with a plate 92a positioned in the platform to accommodate the lower ends of these sleeve members when the barrier is in this position.

To facilitate the assembling,` of the removable portion of the door and step-operating mechanism carried by the barrier 15, With the portion thereof stationary on the platform, 1 provide a locking device 98 coirnnisine` a pin 94 which extends throufrh openings in the tube G9 and sleeve members 70 and 71. and is carried bv a block 95 slidable in a tubular extension 9G on the barrier 15, the block 95 being eouipped WithA a handle 97 movable in a slot 98 in the tubular member 9G. The openings iust referred to in the members 69. 1'0 and 71 are so arranged that when thev are in alinement as shown in 4. in which position the pin 92 mav be pro'iected therethroiiah. the lugs 75 and 7S will resister with the notches 52 and 51, respectiwdv` when the vestibule doors are closed and thebarrier is ip the full line position repnesentefl in Vie. 1. The operato" before shiftino the barrier from the full line position represen-ted in Fie'. 1 to tbe dotted line position represented therein. v'ill first operate the doors to closed position and thereupon prniect the in 90, into the position shown in Fior. 4 for lookin@ the 0n res turnine the barrier to the full line position 4represented in Fig. l, no lpreliminary adjustment' of -the sleeves 70 and 71 is necessary'to cause them to become properly interfitted With the portion of the doonoperating mechanism stationary on the platform, as these sleeves occupy the proper position for the assembling of the lugs thereon with the notched portions of the sleeve members 37 and LiO, upon the act of positioning` the barrier as stated.

While i' have illustrated and described a certain construction Iin which my invention is embodied, 1 do not Wish to be understood as intending` Ato limit it thereto as the same may be variously modiied and altered Without departing from the spirit of my invention, it being my intention to claim my invention as fully and as broadly as the prior state of the art Will permit.
