'made a certain new and useful Invention in Door-Operating Mechanism for Passenger- Cars, of which the followinglsa specification.

This invention relates to door operating mechanism for passenger cars.

The object of the invention is to provide a construction andarrangement of door operating mechanism for passenger cars which is simple and efiicient.

A further object is to provide a construction and arrangement of door operating mechanism wherein a single operating or control handle may serve to operate or control the operation of different doors or of doors on opposite sides of the car.

A further object is to provide an arrangement for facilitating the entrance and exit of passengers to and from the car, and whether the entry andexit of the passengers is accomplished on one side or the other of the car.

Other objects of the invention will appear more fully hereinafter.

The invention consists substantially in the construction, combination, location and relative arrangement of parts, all as will be more fully hereinafter set forth, as shown in the drawings, and finally pointed out in the claims.

In the drawings,Figure 1 is a view in floor plan, parts broken off, and parts in horizontal section, showing a portion of a street car and the application thereto of an arrangement of entry'and eXit way and door operating mechanism therefor, embodying the principles of my invention. Fig. 2 is a top plan view of the control stand, one set of the control arms or-rods being omitted.

Fig. 3 is a view in elevation, parts broken application of a door operating mechanism embodying my lnvention' and an exemplificatlon of an entry and exit way for passenger cars, I have shown a portion of a car wlth slde doorways on opposite sides thereof. As is obvious, these may be at either or both ends of the car or intermediate its ends, as in the case of a center entrance type of car. Where my invention is applied to a car of the center entrance type, the portions at opposite sides of the entrance, indicated at 10, 11, constitute the seating spaces for passengers, and these portions may communicate with the entry and exit platform or landing13i, in any suitable or convenient manner. I shall therefore refer to the platas the landin form portion 13,

and as be distinct from either or both of the seatlng portions 10, 11.

At each side of the landing 13, are three doorways, in the par ticular form shown in the case of a center entrance car, each doorway having a door. I shall refer to the center door of the three at each side of the landing as the entrance door, and the ones on opposite sides of the center one as the exit door. The doors may be of any suitable or convenient type or construction. I have shown the exit doors as of the swinging type, and the entrance doors as of the folding type, but obviously I am not to be limitedor restricted in this respect. Where swinging exit doors are employed, and in the arrangement shown, they are composed'of the swinging sections 14, 15, 14, 15', 16, 17, 16, 17'; and in the case of the folding entrance doors they are j composedofthe folding sections 18, 19, 20, 21, 18, 19, 20, 21'. The door sections 14:, 14, 17, 17 are respectively carried by vertical shafts 22, 23, 24, 25, located at their outer edges and adjacent the door posts 26, 27, 28, 29. Upon each of said door shafts are crank arms indicated indotted lines at 30, 31 (see Fig. 1) through which said shafts are rotated to swing the door sections into open or closed position. Similarly, the door sections 15, 15, 16,16, arecarried by vertical shafts respectively, 32, 33, 34, 35 at the outeredges of said door sections which are located adjacent the door posts 36, 37, 38, 39 and each of said shafts is provided with a crank arm indicated at dotted lines 4O, 41, through which said shafts and with them the cooperating door sections are rocked into their open or closed position. In like manner the door panels .18, 18',-21, 21 are carried on vertical shafts 42, 43, 44,45 having crank arms indicated in dotted lines at 4:6, 4:7 for a similar purpose, the panels 19, 19, 20 and 20 folding back upon the panel 18, 18, 21, 21 respectively, being suitably not, as it is obvious that the same door or door sections may control both the entrance and exit passages.

Located opposite the entry doorway, and in the preferred arrangement, as shown, is a stand 48, which serves to define a station for the conductor or cashier, and at which station is located means for controlling the doors at the entrance and exit doorways. In practice I prefer to locate this station opposite the entrance doorway and at a point midway the transverse width of the landing or platform, and between the entrance doorways on the opposite sides of the car and approximately midway the communication of the platform or landing with the seating spaces of the car. In the case of a center entrance car, or .entrance intermediate the ends of the car, I prefer to locate the conductors station at approximately the mid point of the landing or platform. By this arrangement entering passagers can distribute themselves on one side or the other I of the conductors station in passing from the entry doorway to the seating space of the car at one end or the other, the said station forming a division barrier for this purpose and by defining a conductors station at the point indicated not only are passengers able to pass on opposite sides of the conductors station in entering the car so as to reach the seating space at one end or the other of the car but they also pass by the conductors station where they pay their fares before entering the seating spaces or portions of the car. This very greatly facilitates the entering movements of passengers and the collectlon of their fares before entering the seating portions of thecar while at the same time permitting distribution of the passengers to the respective ends 7 of the car, thereby securing a desirable dis- I tribution of the weight or load of the passengers.

It is obvious that any suitable, convenient or well known means may be located at the conductors station for facilitating the making of change or deposit of fares but as these form no partof-my presentinventionfurther description thereof is an necessary.

If desiredpthe landing portion or plat form 13 may communicate in any desired manner with the interioror seating portlons of the car. In the particular form shown as exemplifying a practical arrangement embodying my invention I have shown bulk-heads between the lanlding or platform 13 and the end portions 10, 11 of the car and comprising or including doorways controlled by doors 4-9, 50, 51, 52 which, in the form shown, are of the sliding type and designed to slide into pockets 58, 54, 55, 56 in a well known manner, said doors operating transversely ofthe car, eachcooperating pair meeting at a center post 57, 58, when closed. Suitable barriers, indicated at 59, 60arearranged 'on opposite sides of the control stand 48, the functions of which are to divide'the landing space into separate passageways forentering and alighting passengers, the passageway for entering passengers being directed alongside the control stand whereby the entering passengers are compelled to pass in convenient relation to the controlstand to enable the conductor at the control stand to collect their fares before they pass on by and into the seating space of the car. At the same time these barriers afford convenienthand grips for passengers-while passing along the passageways, whether'entering or leaving the car. The barriers v59, 60, may have any suitable or convenient arrangement and relation. In the particular form shown, and in order to illustrate my invention, the barriers extend from the center landing posts 57, 58, respectively, to the posts 36, 38 on one side of the landing which separate the exit from the entrance doorways. Where the opposite side of the landing is used the barriers are turned or reversed so as to extend from thecenter posts 57, 58, to thedoor posts 37, 39 on theoppos'ite side of the landing, as indicated in dotted lines in Fig. 1. My invention, however, in its broadest scope, as defined in the claims, is not to be limited to the specific arrangement shown and above described. It is obvious that the doors to, 50, 51, 52, which separate the landing from the interior of the seating space of the car may be omitted, if desired,

in which event the: interior seating portions of the car communicate unobstructedly with the landing, with means located on the landing or platform to direct incoming and leaving passengers in different paths or streams so as not to interfere or to block each other, i

In the practical operation of a car constructed and arranged as above described,

entering passengers, board the car onto the portion 61 of the landing or platform 13,

either with or without side steps, indicated at 62, according as the car is of the low or high floor level type. It is also obvious that any suitable or well known type of step, either fixed or foldable, accessible or inaccessible, and operated in any convenient or well known way, may be employed. From this point 61, which is in front of the control stand, or between said stand and the entering doorway, in the particular arrangement shown, the passengers are directed by the barriers 59, 60, past the control stand on their way toward the seating spaces of the car. In the particular arrangement shown the passengers have their choice of passing to one side or the other of the control stand through the passages indicated at 63,64, and thence on through the doorways or passages, 65, 66, into one or the other end or seating portions of the car, as occasion may require. Passengers desiring to alight from the car will be directed from the seating spaces. at the opposite sides of the landing or platform 13, through the passages 67,68, to the exit doorway. Of course it will be understood that when one side of the landing or platform is utilized for boarding and alighting passengers, the doors on the opposite side of the platform are kept closed. It will also be understood that while the conductors station is at the control stand, ordinarily he will position himself between the control stand and the closed side of the landing or platform, or the side thereof which is not being used as an entering or exit side. At the same time the conductor is permitted a considerable freedom of movement while still remaining within easy reach of the control stand.

The .doors, where such doors are employed at the sides of the landing may be operated,

or the operation thereof controlled in any suitable or convenient manner and by any suitable or convenient construction and arrangement of operating and control devices. I have shown a simple construction and arrangement of devices for this purpose which embodies many advantageous features and which I will now describe.

Suitably journaled in the control stand 48, are the vertical shafts 69, 70, 71, upon each of which is secured an operating handle 72, 73, 7 4, by which said shafts may be rotated. Also mounted upon each shaft, in one form of construction embodying my invention, are two cam plates or members 75, 76, see Fig. 3, each provided with a cam track or groove. In Fig. 2 the cam track or groove of the uppermost plate or member of each shaft is indicated in dotted lines at 77. The cam grooves in the plates 75, 76 are peculiarly shaped. Thus each plate is provided or formed with a groove which is curved concentrically with the aXis of the shaft on which the plate is mounted, for a portion of the length of the groove, and is eccentric to the said axis for another portion of its length. Associated with each cam plate is a pivotally mounted lever engaging at one end in the cam groove thereof. Thus, in Fig. 3, a lever 78, is pivotally mounted as at 7 9, and has its end 80 engaged in the cam groove of plate 75, while another lever 81, pivotally mounted as at 82, has its end 83 engaged in the cam groove of plate 76. The cam plates 75, 7 6, mounted on the same shaft are so related to each other, and so relatively arranged that when the control handle as 72, thereof, is turned in one direction from a normal or initial position, the engaging end of one of the levers 78, 81 will be engaged by the concentrically curved por tion of the cam groove 77, in its associated cam plate or member, and consequently, said lever will be held against rocking movement, while at the same time the end of the other lever will be engaged by the cam portion of the groove in its associated cam plate, and consequently said lever will be rocked. One of the levers 78, 81 is designed to be connected to doors on one side of the landing while the other is designed to be conducted to the corresponding doors on the opposite side of the landing. Thus in the arrangement shown, lever 78, is connected through rods 84, 85, with the crank arms 31, 11, respectively, of door operating shafts 24, 34:, while lever 81, is intended to be similarly connected to crank arms on the door operating shafts 23, 33, on the opposite side of the landing. In the same manner the cam plates on each control shaft operate pivoted levers which are respectively connected to corresponding doors on opposite sides of the landing or platform, and said cam plates are so relatively arranged that when the handle of the control shaft is turned in one direction from a control or initial position the door on one side of the landing will be operated While the corresponding door on theother side of the landing will not be operated, and when said control handle is turned in the other direction from its cen* tral or initial position, the reverse of this action will take place. Of course it is to be understood that a sufiicient range of movement of the control handle on each side of its initial position is permitted to enable the working door to be opened and closed without moving the corresponding door on the opposite side of the landing.

From the foregoing description it will be seen that I provide a construction of door operating devices wherein a single control handle controls the operation of doors on opposite sides of the landing but that one of the doors is not operated when the other is in operation.

In the construction above described two separate cam plates are mounted on the same control shaft, one concerned in the operation of the doors on one side of the landing and the other concerned in the operation of the corresponding doors on the opposite side of the landing. In some cases I may dispense with one of the cam plates and use only one with each control shaft. Such a construction is shownin Figs. 4 and 5. In this case a single cam plate 86, is mounted on each shaft 69, 70, 71, each cam plate having a cam groove which is curved concentrically with its aXis between the points 87, 88, in one direction peripherally thereof, as indicated at 89, Fig. 5, and is cam shaped between said points 87, 88, on the other peripheral direc tion, as indicated at 90. In this arrangement the ends of both levers 78, 81, engage in the same cam groove, but when the control shaft carrying the cam plate is turned in one direction from an initial position, the engaging end of one of the levers will work in the concentric portion of the cam groove while that of the other lever will work in the cam portion of the cam groove, and when the control shaft is turned in the other direction the reverse of this action takes place, thereby securing identically the same operation as above described with reference to the arrangement shown in Figs. 2 and 3. In this arrangement both doors may be opened, if desired, by the movement of the control handle in the same continuous direc tion. The doors will be opened consecutively, however, and not in unison, and a reverse movement of the control handle will in like manner close the doors consecutively.

Having now set forth the object and nature of my invention and various constructions and arrangements embodying the principles thereof, what I claim as new and useful, and of my own invention, and desire to secure by Letters Patent is,
