Specification of Letters Patent.

Patented Jan. 4, 1910.

Application filed August 19, 1909. Serial No. 513,602.

To all whom it may concern:

Be it known that I, HARRY H. ADAMS, a

- citizen of the United States, residing in the c ar, but also to enlarge the passageways particularly at the entrance and exit so as to facilitate as much as possible the rapid ingress and egress of passengers. -This tendency to facilitate the movement .of passengers in getting on and ofi' cars is particularly noticeable in connection with pay-as-youenter cars, in connection with which it i's sometimes diiicult'to maintain the desired space for passageway and doors because of these limitations, the' width of the door opening in cars as now commonly construct-f e the barriers employed for guiding passen- .gers in this type of car. '4

My present invention relates to an L iniprovement in the construction of street 'railway cars with the object of obtaining the maximum width of doorways through the end walls of the car. As now constructed the end doorwa s are closed by centrally divided sliding doors which open intoside recesses or pockets formed in the end walls of lthe car. The width of the door opening is necessarily limited in this form of car by the width or extent of the door receiving pockets or recesses, which are inturn limited by the presence of the main vertical corner posts of the car body. By reason of the end walls will escape the limitations of the corner posts. By this arrangement I am able to construct a car with an available doorway of approximately one half the entire free exterior width between the side walls of the car, since the sliding doors for closing the doorway are permitted to move into their pockets or recesses to the inner faces ofthe Ioutside skin or sheathing of the car. l

In order that my'invention may be fully understood, I will first describe the samey with reference to the accompanying drawings and afterward point out the novelty more particularly in the annexed claims.

In said drawings Figure 1 is a diagrammatic'plan View or floor plan with the central part broken away, of a street railway car embodying my invention. Fig. 2 is a detail end elevation' of the same with the platform and vestibule omitted. Fig. 3 is a-detail horizontal plan view of a part of the same. Fig. 4t is a view similar to Fig. 3 of a slight modification. l

Without going into immaterial details as to the general construction .of the street railway car to which my improvement relates, it will be observed from the drawings that 1 is the car floor, 2 the paneled side walls, 3 the end walls, and 4 the end platforms around which are built vestibule walls 5.

The side walls are built upon` the upright central doorway.15 which it is desirable to construct with as wide a free openingv as possible .to facilitate the movement of passengers. The doorways 15 are closed by two rigid panel sliding doors 20 hung in the usual manner upon track bars 21 and 22, extending above the door opening and to the sides thereof. These sliding doors 20 meet, when closed, in the central vertical longitudinal plane of car, and rest, when opened, in pockets or recesses 25 formed between the panels of the end walls 3 upon opposite sides of the door opening 15. As stated above the extent of these door receiving pockets or recesses is usually limited by the presence of the corner posts at the four corners of the car body. f In my im roved construction, as shown particularly 1n Fig. 3, I have formed each corner post of two studs lOand 10a separated as shown and rigidly braced together byV steel plates 30 and 31 and by the other parts ilo of the car which are built upon the corner post studs. ner post `is arranged flush with the inner panel of tlieend wall, while the auxiliary stud section 10a is arranged flush with the outer panel of Said end wall, so that each door receiving pocket or recess 25 will 'extend to the outer skin or sheathing of the car between corner studs 10, 10a, thereby giving the door receiving pockets or recesses the greatest possible width so as to receive a greater width of door and permit the use of a wider doorway or opening.

In Fig. 4: theauxiliary part l0a of the corner post is in the form of a metal bracket or plate 35, and the door 20 is hung to slide upon the outer face of the end wall of the car, the usual front anel of the end wall being omitted, if pre erred.

What I claim is:

1. In a car construction, 'the combination with a car body having a centrally arranged doorway in its end wall of approximately one Ahalf the entire free width of the exterior of the car, separated studs forming divided vertical corner posts or supports, door receivin pockets in the end wall of the car upon bot 'sides of said. doorway, said The main stud l0 of each cor-- pockets extending between said separated studs to the side walls of the car, and centrally separating rigid sliding doors mounted in said door receiving pockets and adapted, when open, to aord a free passageway of substantially the entire Width of the doorway. 2. In a car construction, the combination of the car body having a floor, side walls and end walls, each of the end walls being provided with a central doorway of approximately one half thefentire free`width of the exterior of thelca'r, vertical corner`posts atv HARRY H. ADAMS.
