To all whom it may concern:

Be it known that I, WILLIAM E. GILES, a

subject of George V, King of Great Britain View of my improved device applied to a and Ireland, residing at New Haven, the county of New Haven and State of Connecticut, have invented certain new and useful Improvements in Car-Steps, of which the following is a specification, reference being had therein to the accompanying drawings.

My invention relates to a new and 1mproved car step, having for its object, among other things, to construct a device of this character, with two or more steps that will open or close synchronously, and capable of operation by manual or other means; a further object being to design the device that it may have great strength and rigidity and of few parts that may be economically constructed, readily assembled, and the device as a unit applied to any car.

To these, and other ends, my invention consists in the car step, having certain details of construction and combinations of parts, as will be hereinafter described and more particularly pointed out in the claims.

Referring to the drawings, in which like numerals of reference designate like parts in the several figures; Figure 1 is an end car body; Fig. 2 is a fragmentary side elevation thereof; Fig. 3 is an elevation of one of the hangers, looking from the left of- Fig. 1, with some of the parts adjacent thereto; and Fig. 4: is an end elevation of a modified form of my invention.

Referring to the drawings, the car body is designated by the numeral 1, to which is secured a pluralityof hangers 2, within which I is rotatably mounted the shaft 3, preferably constructed of tubing. Upon this shaft are a plurality of dogs 4, to which is attached the lower'step 5, having a toe board 6 upon the inner side thereof.

Upon the shaft 3, adjacent to the end hanger, is a dog 7 constructed in substantially the same manner as the dogs 4, but

having a crank arm 8 thereon, to which is secured one end of a turn buckle connection 9,. the'other end of which is secured to a hand lever 10. This lever is pivotally mounted upon a stud 11 in the bracket 12, secured to the car body 1. The turn buckle connection 9 is constructed in the usual manner, the distance between thelever and crank arm being adjustable through the central nut forming part thereof.

Upon the inner ends of the dogs 4 and 7 is a lug 13 that contacts with a lug 14 into: I gral with the hangers 2 and thereby limits the movement of said dogs so as to hold the lower step 5 in a horizontal position and take-the weight and pressure placed thereon. Movement of the lever 10 upon its pivot mounting from the position shown in full lines to that shown in broken lines, in Fig.1, rotates the shaft 3, and, the dogs connected therewith through the turn buckle connection 9, and lifts the lower step 5 from its horizontal position to a substantially vertical position that is shown by broken lines in Fig. 1. I

I have not shown the construction of the upper end of the lever 10, as it constitutes -n o part of my invention, any form or type of lever being adapted for this purpose, which may be locked by any preferred form of locking means so as to prevent accidental or improper manipulation thereof. A lever may be located, however, at each end of the car, if desired, so that the person operating the car at either and may raise or lower the steps.

Rotatably mounted in the hanger 2, between the car body 1 and the shaft 3, is a shaft 15, also preferably made of tubing, upon which is secured a lurality of do 16, having a counter-weight 17 upon their inner ends, and to the outer ends of which is attached the upper step 18,- connected with the lower step by the chains 19. When the upper step 18 is in its horizontal positio shown in Fig. 1, the counter-weight 17 contacts with the underside of the body 1, so that the weight or pressure upon said upper step is taken. by said body member. The

ingshown by broken lines in Fi 1.

The device herein illustrated and described is manually operated, but as many cars are provided with air brakes, and hence have an air pressure system connected therewith, this may be utihzed for the purpose of movement of the lower step 5 fromits vertical to its horizontal position imparts a like counter-weight 17, this vertical position be- '25 5 do notlimit myself to the exact construction operating "m improvedstep. Totake ad vantage of t issystem, I provide a cylinder 20, that is connected to the body 1, and within which is movable the piston head 22 that is connected with the arm 23, integral with thedog7 through a piston rod21. Air is admitted into the piston through a pipe .24 in a well known manner. rTheope'ration of the shaft 3 and the other parts of my improved device will be exactly the same through air pressure means just ,described as ifthe-said shaft were operated manually. Theflconstruction of the air cylinder and the means for admitting and taking air I ations that can be made ithin ,myinvention, aside from those herein suggested, and I would therefore have it understood, that I herein; shown andv described,'but claim all that fallsfifairly within the spirit and scope of lmy invention.

contact with said hangers; weighted dogs upon the other shaft; a step secured to the dogs upon each of said shafts; a connection,

between said steps; and adjustable means,

controlled from the body of the car, for operating one of said shafts.

2. Ina device of the character described, the combination with a plurality of hangers, designed for attachment to a carbody; of a shaft rotatably mounted therein adjacent to its lowerend; a second shaft also rotatably mounted .t herein at. a point between said shaftand said car body; a plurality of dogs connected with said lower shaft, having means thereon that contact said hangers and limit the movement thereof in one direc; t10n; 'a. step connecting all of said. dogs;

means connected with said shaft and controlled, from the body of the car for impart-- mg a rotary movement to said shaft; a

.i of dog s econd shaft and having a counterweight upon one end thereof; a step attached to said last mentioned dogs; and a connection between each of said steps.

3. In a device of the character described,

the combination with a plurality of hangers, designed for attachment to a car body, said hangers having a laterally projecting arm at their lower end; a shaft rotatablymountedin said arms;a plurality of dogs connected with said. shafts, at least one of said dogs having ant-rank arm connectedtherewith; means connected withsaid. dogs for limiting their movement in one direction; a.
