Ser'alifNoL/'43,378. y i i To all whom it may concern: y e 1 Be it known that I, CHAnLnsWILLiAM MALLINS, a subject of the King of Great Britain, and residing in Liverpool, England, have invented certain new and useful Improvements in T ram-Cars, of which the following is a specification. This invention relates to tramcars, and the object is to so modify the construction of a double deck bogie car as to provide for separate exits and entrances, wherebyy passengers boarding the car or ascending to the upper deck, are kept quite distinct and apart from the passengers leaving the inside or descending from the upper deck; whereby the seating accommodation for a given size of car is utilized to the fullest ypossible extent; and whereby the opposite ends of the car are quite symmetrical; and so that the entrances and exits are separately located on the near-side kin whichever direction the car is running.I

The invention also comprises certain improvements in devices to deter or caution assengers from boarding or leaving the lcar when the latter is in motion, or after the signal has been given to the driverfto proceed.

The invent-ion is illustrated in the accompanying drawings in whichf Figures 1 to 6B show the general arrange-` ment of the car, and Figs. 7A to 1,1 show details of the signaling devices. Fig. L1 is an elevation; Fig. 2 aplan in vsection onthe line II, II, of Fig. 6B, showing the seating and platform arrangements ofthe upper deck; Fig. 3 is a plan 1n section on the line III, III, of Fig. 1 showing the seating and platform arrangement of the` lower deck; Fig. t is a transverse section on the lme IV,

IV, of Fig. 1; and Fig. 5 is aitransverse section on the line V, V, of Fig. v1.v Figs. 6, 6A and 6B are views to aflarger scale showing the arrangement ofthe main platform; Fig. 6 is an elevation; Fig. v6A isa plan, and Fig. 6B isa transverse sectionon the line VI,

VI, of Figtg.` Fig.y 7 is a detail of they signal` arm. f n .A .f The arrangements of the bogie trucks, wheels, brakes, motors and controllers may be of any type suit-ablefor the construction l of body'abouti'to be described, and are in general `omitted from the drawings ;-the lifeguard is preferably that known as the Liverpool type. i* i y y Themain body ofthe car extends vfor nearly the whole length of the' car leaving a` driving platform A at each end, over which platform the said platform being vopen atthe sides, or being inclosed, as may be desired. Thecentral portion of thel main body vided off from the interior, and forms a central platform D by which passengers `board orleave the car. Two stairways are prov1ded,having the inside lstringers set at an anglewith kthe tread, and from the central platform to theupper deck, one F` an as'- cending stairway for thoseLboarding, and the other E a descending stairway for those leaving. Theside opening ofthe platform D, which is providedwith a suitable step all, is divided by two vertical posts @Z2 and d? into three parts, a central entrance and' two laterally arranged exits. f

The inside of the car is 'divided by the central platform into two compartments, the

smaller of which C, may be adapted for rst class passengers and the larger C for ordinary passengers. yThe entrance to each compartment is by `double door-ways `01, c2 and upper deck B extends,

c, c', is dii barriers are arranged so that passengersy i boarding the car by the cent-ral in consequence of the barrier, enter the f inside ofthe vcar `by the offside half of the doorways, or to ascend to the upper deck by the off-side stairentrance are,

' way F; -whereas passengers alighting must leave the car by kone or other of the side exits, beingy directed thereto from the 'near' side half of the doorways of the inside compart: ments, or bythe descending staircase' E from the upper deck. It will be seen that for opposite directions posite sides of the platform are on the near side; the barriersreferred tok must therefore beso arrangedfthattheyncan be swiveled so astof make the near side ofthe platform form the entrance andjexits in whichever direction the car is running; theolfside of the platform must of course be closed and this can'be done by means of a balanced compelled to ofmotion of the car, .opi n y guard rail, or the barriers may be arranged so that they can be lused alternatively for directing the passengers on the near side and forclosing-in the platform on thel off? side. The preferred arrangement of the barriers is as follows The double stanchion if is fixed opposite the meeting stiles of eachA pair of doors, and swiveling barriers d? andn cls which may be ornamental iron work hinged doors are provided, and'pivoted at Z5 and ZG to the posts cl2 and da as shown; when the car is traveling in the direction of the arrow Z, (Fig. 6A), these barriersare arranged as shown in Fig. 6A, so that they form a central entrance and two side exits on the near side, and completely close in the off-side; when the car is running in the opposite direction to that indicated the arrangement of the barriers Z7 and ZS is reversed. The seats G generally are arranged transversely, but are, of course arranged to fully utilize the space and some of them, such as g1 may be arranged as drop seats so as to give clearance spacev when desired. The whole of the upper -deck is closed' iny by the roof II, and the stairways E and F are accordingly fully protected. Doorsa1 are provided at the end of the two lower deck compartments to give access to the drivers platforms A. IVith this arrangement, a car having an over-all length of 35 feet may be arranged to have a total seating capacity for eighty-four passengers.

he arrangement of barriers and entrances to the lower deck compartments and the arrangement of t-he stair-ways and seats, may of course be modified within the limits of my invention to meet any special cases.

The location of the platform in an approximately central position, as described has the advantages that the platform is protected from the weather; that all passengers boarding or leaving the car are brought to a focus under the control of4 the conductor; that the weight of passengers assembled on the platform is Yevenly distributed,- as distinguished from the case of cars with end platforms, when the weight of passengers assembled on t-he rear platform tends to tilt the car.

The car body is carried on a gap frame to permit of the platform being arranged several inches below the carfloor, to reduce the height of the step.

In order to deter passengers from attempting to board or leave the car when it is in motion, or after the signal has ybeen given to the driver to proceed, light arms O may be mountedon the vertical posts cl2, Z3 at the entrance and exits so that in one position they extend across the entrances and exits,- and in the other position ,are clear of them. The arms (see Figs. 7 and 6) are preferably pivoted on sleeves o1 on the vertical posts cl2, CZ?, and suitable pulleys 02 on the sleeves are connected yto a spring 03 which normally holds the arms in the clear position. The

vthe electro-magnet is energized and draws the'arms into the obstructing position. In a similar manner,`the pulleys are also connected by a cord to a lever 08 operated by the p conductor in such manner that when he sig# nals the driver to proceed, the arms are drawn into the obstructing position and that when he signals the driver to stop, they are turned from the obstructing position when the car comes to a stand; the Said lever may operate the signal bell through a dash pot arrangement so as to give a 'time interval. Y

i The cars are fitted with balanced windows andI ventilators Itis convenient to have the entrance at the 'center .and the exits at the sides of the platform, the entrances may however be at thesides andthe exit at the center in which case E would be the ascending stairs and F the descending stairs.

Having now fully described my invention, I declare that what I claim and desire to secure by Letters Patent is 1. In a double decker tramcarA in combination :-a central platform dividing the lower deck into two compartments; a doorway from each compartment to the platform; two separate stairways from the platform to the upper deck; two stanchions dividing the side entrance to the platform into two wing sections and one central section; barriers extending respectively from opposite the center of each vofthefdoorways to the adjacent stanchion, one of the said barriers dividing off a portion of the plat-form which communicates with one half of one of the doors, one ofthe staircases and one ofL the wing sections of the side entrance, and the other barrier dividing off a portion of the platform which communicates, with one half `of the other door and the yother wing section ofthe side entrance, the remaining portion of the platform communicating with the other staircase and the other halves of the two doors; substantially' as described.
