ll IF II II J] I JIF RICHARD'I-IILLIER, OF NEWARK, NEW JERSEY.

EXTENSION-STEP.

To all wiwm it may concern:

Be it known that I, RICHARD HILLIER, a citizen of theUnited States, residing at Newark, in the county of Essex and State of New Jersey, have invented new and useful Improvements in Extension-Steps, of which the following is a specification.

This invention relates to what is generally known as floating platforms for passenger coaches, and it consists in the novel features hereinafter described and claimed.

An object of the invention is to provide a platform or gangway pivotally connected with the side of a car or coach, and having means operatively connecting the same with a sliding or movable door, whereby the platform is folded up against the side of the car or coach when the door is moved to a closed position, and the said platform is permitted to swing in a downward and outward direction when the door is moved from a closed to an open position.

Another object of the invention is to provide in a structure of the character indi' cated, an arrangement of parts which will prevent minimum obstruction to a movement of the passengers over the same when the platform is in a lowered position. Also the platform is brought in close contact with the side of the door and car when the same is swung to an upper position, consequently its presence upon the car does not offer obstruction to the movement of the car along the trackway and by objects end is connected with the outermost section of the floating platform. The intermediate portion of the said flexible member is trained over a pulley mounted at the side of the car in the vicinity of the upper edge of the door, consequently when the door is open the floating platform may swing in an outward and downward direction and when the door is moved to a closed position,

the said floating platform is folded up in close proximity to the side of the car and i the door.

In theaccompanying drawing :Figure 1 1s a side elevatlon of a portion of a car wlth the floating platform applied. Fig. 2 is a perspective View of the floating platform.

Fig. 3is a transverse sectional view of the floating platform, portion of the station platform and part of the car showing the parts in position when the upper surface of the station platform is approximately at the same level as the upper surface of the floor of the car or just a little above the same. Fig. 4 is a similar view showing the relative positions of the parts when the upper surface of the station platform is below the upper surface of'the floor of the car.

As illustrated in the accompanying drawing, the car body 1 may be of any usual form or pattern employed for transporting passengers and the said body is provided with a sliding door 2, located at its side.

The floating platform includes a section 3 preferably of sheet metal, which is hingedly or pivotally connected with the side of the body 1 approximately at the level of the floor of the body and below the opening of the door 2. The said section 3 is provided at its inner edge with a curl 4 which is turnably mounted upon a rod 5 supported in lugs 6 attached to the lower portion of the side of the body 1. The section 3 is further provided at its outer or free edge with a curl 7 which receives and retains a rod 8. The floating platform also includes an outer or upper section 9 also of sheet metal. The section 9 is formed with knuckles 10 which are turnably mounted upon the rod 8. The inner-edge portion of the section 9 between the said knuckles and beyond the same lies over and against the upper surface of the section 3 as at 11 as most clearly shown in Figs. 3 and 4 of the drawing. A chain or flexible member is connected at one end with the outer portion of the section 9 and at its other end with the upper portion of the door 2. The intermediate portion of the said flexible member 12 is trained over a pulley 13 which is mounted at the side of the body 1 in the vicinity of the upper edge of the door 2.

The parts of the structure are so arranged that when the door 2 is in a closed position as illustrated in Fig. 1 of the drawing. the sections 3 and 9 of the platform are swung in an upward direction and lie in close proximity to the side of the body 1 and the andcOnSequent'lyi'thesections 3* and 9 may" swing in a downward and outward direction and the section 9 may'engagethe upper surface of a station platform as illustrated @in Figs! L of the drawing, Inftheeve'nt that the upper surface of the station; plat- .form is approximately at the same'le'vel 'as the upper surface of the floor lof theem 2 as, shown in Fig, 3the under surface of'the section 9 will'lie fiat upon the upper surface anglebetween thesect'ionsB and 9, but 'this angle fis'fnot sufficient to cause the inner'edge "portion ll' of the section 9 topi'bject-upfand lintiife-riwith t mo ement of the passengells- .QVBF the; platform,

i In the event that the upper 7 surface of :tlie 'station'platform is lower than the upper surface, of the floor of the car fasjshown inF ig. 4 of the drawing, 'the inner edge portion 11 of the section' 9 will engage the upper 'surface of thefe section 3, and the said sections 3 wide are thereby heldin' parallel relation and consequently the floating platform -assumes an a inclined I position down "which the passengersfmay readily pass without encountering obstruction.
