EXTENSION -STEP FOR RAILWAY-CARS.

- I Application filed April 13,

I To all whom it mayho'ncern:

Be it known that I. OLor F. Lawson, a cit-ize-niof the United States, residing'at New Sharon, in the county of Mahaska and v State of Iowa, have invented new and useful IS'Tn' sta'tion platform so as to obviate the step' of the car.

,necessity of using a stool orthe like when passengers'are getting one]; on the train.

In the drawing, forming a portion of this specification and in which like numerals of reference indicate similar-parts in the several views :1 F igure 1" is a perspective view sl'iowing my extensible step applied to the usuat pern'ianent step of -a car, the ex-.

tensible step being shown in its extended or operative position. Fig. 2 is a section on line 2-2 of Fig. 1 showing the extensible step folded beneath the bottom permanent step of the car. Fig. 3 is a section on line 3-3 of Fig. '2. I

For the purpose of illustratiom-"a portion A of a car. is shown in the drawing, the same being provided with the usual permanent steps B.

My improvement resides in the provision of an extensible step l which is disposed below the plane of t-helowermost permanent The extensible step embodies a main stop member 2 and a riser 3, the latter being hingedly connected with the former by bracket plates 4 so to permit the members 2 and 3 to be folded on each other as-shown'in Fig. 2 of the drawing. The riser member 3 of the extensible step is mounted on a pivot bar or rod 5 which is mounted in suitable bearing passages 15 in the members 7 and 8 of the ear. The riser 3 of the-extensible step is spaced from the portion 8 of the car by a grooved roller S).

This roller pivot bar 5.

A lever 10 is pivoted, at 11. to the platform 12 of'the car, and as shown, the lower end of the lever is pivoted, ltt'lii, to an actuis mounted on one end of the Specification-of Letters P ten Patented J uly 16, 1912.

1911. Serial no. 621,775.

' e ating rod 14. the outer end of the rod hav ing pivotal connection twith the stud L?) which extends outwardly from one end of the riser 3. Achain or similar flexible connection 16 is connected at one of its ends with the lever 10, the oppositeend of the chain being extended over the guide roller 5) and being attached, at 17. to the section 2 ofthe extensible step.- The upper end of the lever is preferably located in close proxable in a guide 19 which is suitably secured to -the end of the car. This guide provided-with teeth 20 which are designed to engage the lever so ,as to hold the same in 'its adjusted position.

From tlIG OOIIStIUCilOD described it will be readily, understood that the lever 10 is adaptedfor manual operation so as to ob- 'imity to the door 18 of the ear and is slidtain the two adjustments of the extensible step, it being understood that when the lever is moved in one direction the step may be extended to the operative position shown in Fig. .l. of the drawing. and when the lever is moved in an opposite direction the step sections 2 and 3 are folded one upon the other and disposed beneath the lowermost permanent car step.

\Vhen my improved step is in its extended-position it will be disposed in such proximity with respect to the ground or station platform that will entirely obviate the necessity of providing-the stool which is-so commonly employed and used as a supplemental step when passengers are boarding or leaving the car. \Vhen the step is in -.its extended position the chain 16 will operate to hold the section 2 thereof securely in a horizontal position.

I claim r The combination with a permanent car step having-a depending member at. one side thereof, of airextensible step located beneath the permanent step and including a tread and a riser member, said members being pivotally connected with eaclrother, a, pivot rod supporting the riser member and having its extremities mounted in hearings in said depending member and car. respec mediately below said permanent step, a controlling lever, a horizontally disposed actutively. a grooved roller supported by one end of the said pivot rod and disposed nn-' uting rod connecting the lever and the riser member of the extensible-step, and :1 flexible inpresence of two witnesses.

connection extending over the roller iind i OI'OF I AVQOY having connection with the controlling lever l J and with the tread menihcr for the cxtensible step, substantially urnl'tor the purpose specified.

In testimony whereof I affiX rny'signature
