EXTENSION CAR-STEP.

Specification of Letters Patent.

Patented Aug. 21, 1906.

Application filed March 19, 1906. Serial N0. 306,833.

T0 all whom, it 1mi/y concern.-

Be it known thatl, EDGAR S. MITCHELL, a citizen of the United States, residing at Homer, in the parish of Claiborne and State of Louisiana, have invented new and useful Improvements in Extension Car-Steps, of which the following is a specification.

This invention relates to steps for passenger-cars, and has for its object to provide an extra step that can be extended into position for use when the distance from the ordinary fixed steps is too great for the convenience of passengers entering or leaving the car.

Afurther object is to provide a step of this kind which can be withdrawn out of the way when not needed or when the car is moving.

In the accompanying drawings, Figure 1 is a side elevation showing the extension-step withdrawn. Fig. 2 is a central vertical section showing the step extended into position for use, and Fig. 3 is a rear view.

Referring specifically to the drawings, 5 and 6, respectively, denote the side supports for the ordinary fixed steps of a passengercar. The extension-step (indicated at 7) is connected at its front end by links 8 to the side supports 5 and 6 in such a manner that it can be swung forwardly or rearwardly, as shown in the drawings The step is swung by means of a rock-shaft 9, from which extend arms 10, which are connected to cheeks 11, extending from the step 7 at the rear end thereof. The rock-shaft is journaled in the side supports 5 and 6 behind the first riser 12 of the fixed steps, and one end of saidshaft extends through the side support 5 and is bent to form an operating-lever 13 to actuate the shaft. To this lever is pivoted, as at 14, a bar 15, carrying a pin 16, which extends through a hole in the lever 13 and is engageable with holes 17 in a plate 18, secured to the side support 5. Two of such holes are made in the plate 18, one of which receives the pin 16 when the step is down and the other when the step is up. A spring 19, secured to the lever 13, presses on the bar 15, whereby the pin 16 is held in engagement with the stop-holes 17, and accidental disengagement thereof prevented. The rockshaft 9 is so positioned that when the step 7 is swung forwardly in position for use the arms 10 will engage the riser 12, which is thus made to serve as a stop to limit the forward movement of the step.

An extension-step constructed as herein described is simple and easy to operate, and it effectively serves the purpose for which it is intended. When the step is withdrawn, as shown in Fig. 1, it is out of reach of any structures or obstacles that may be along the side of the track, and it is therefore not liable to damage. The latch carried by the operating-lever 13 securely holds the step in position.

I claim- 1. The combination with a car-step, of a rock-shaft ournaled in the side supports of said step, an extension-step, links pivoted to the aforesaid side supports and connected to the front end of the extension-step, and arms extending from the rock-shaft, and operatively connected to the rear end of the extension-step.

2. The combination with a car-step, of a rock-shaft ournaled in the side supports of said step, an extension-step hinged at its front end to the aforesaid step, and an arm extending from the rock-shaft and operatively connected to the rear end of the extension-step.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.

EDGAR S. MITCHELL.
