EXTENSION CAR-STEP..

Specification of Letters Patent.

Patented Sept. 12, 1905.

Application flied May 11, 1905. serai No. 259,891.

T all whom 771 muy concern.-

Be itknown that I, GEORGE GRANT COMER, a citizen of the United States, and a resident of Kalama, in the county of Oowlitz and State of llashington, have invented a new and Improved Extension Oar-Step, of which the following is a full, clear, and exact description.

This invention relates to improvements in extension-steps for passenger cars or coaches,

the object being to provide extension-steps that may be readily attached to the ordinary fixed steps and so arranged as to be easily moved to and held in its lowered position and moved automatically to its upper position when not required for use.

I will describe an extension car-step embodying my invention and then point out the novel features in the appended claims.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in both the figures.

Figure 1 is a perspective View of ay portion of a car, showing an extension-step embodying my invention; and Fig. 2 is a front View thereof, partly in section, on theline 2 2 of Fig. 1.

Referring' to the drawings, 5 designates the ordinary car-step fixed to the side boards 6.. The extension-step 7 has extended upward from its ends rods 8 9, the rod 8 being guided between two pairs of curved rollers 1011, mounted on a metal plate (preferably steel) 12 to one of the side boards 6. The rod is also movable through a bracket 13, extended outward from the said plate 12', and a spring 14 surrounds the rod, engaging at its lower end with the bracket 13 and at its upper end with a cross-head 15, rigidly secured to the rod 8. The rod 9 is also guided between a pair of lower rollers 16 and a pair of upper rollers 17, and a bracket 18, secured to a metal plate 19 on the frontside board of the steps, has a perforation in which the rod 9 is movable. A spring 20 surrounds the rod 9, en-

gaging at its lower end with the bracket 18 and at its upper end with a cross-head 21, attached to the said rod 9. The step is limited in its downward movement by the cross-heads 15 and 21 engaging' the upper sides o'f pins 22,- extended outward from the plates 12 and 19.

The front rod 9 is moved outward underneath the platform-sill 23,` the said sill having a recess 211 on its under side to permit said portion to move sufliciently upward to bring the extension-step up against the under side of the lower step 5; From the outwardlyturned portion 25 the rod is continued upward in front of the sill, as indicated at 26, and above the sill it is provided with a foot-plate 27. If desired, the part 26 may be still further continued upward between guides 28 on the platform-rail 29 and provided at its upper end with a handpiece 30. It is to be understood, however, that the rod may be operated wholly by foot-pressure. On the upward extension 26 of the rod is a lug 31, designed to engage against the under side of the sill 23 to hold the extension-step in its lowermost position. A spring 32, attached to the sill 23 and engaging against the outer side ofv the rod-section 26, will serve to force the lug 31 underneath the sill.

In the operation when itis desired to lower the extension-step the section 26 of the rod is to be forced downward, and as it is somewhat resilient when the inclined lower edge of the lug 31 engages with the sill 23 the saidrodsection 26 will move upward, permitting the lug to pass down the outer side ofthe sill until it is moved underneath.

Having thus described my invention, I claim as new and desire to secure by Letters Patent-- 1. The combination with fixed steps of a car, of an extension-step, rods extended upward from the ends of said extension-step, guides on the side boards of the fixed steps between which said rods move, perforated brackets on said side boards through which the rods pass, cross-heads'on the rods, springs arranged between said cross-heads and said brackets, one of' said rods having an upward extension, and means for holding the extension-step in lowered position. A

2. The combinationf-with fixed steps of a car, of an extension-step, rods extended upward from the ends of said step, guides on the side boards of the fixed steps between which said rods move, perforated brackets on said side boards through which the rods pass, crossheads on the rods, springs arranged between said cross-heads and said brackets, one of said rods having an upward extension, a lug on IOO said extension for locking tbe'eXtension-step in lowered position, and a spring for moving the lug to looking position.

3. The combination with fixed steps of a car, of metal plates secured to the outer sides of the step, side boards, upper and lower pairs or' rollers on said plates, perforated brackets ori-said plates, an extension-step, rods extended upward from said step and engaging between the rollers, and also passing through the perforations of the brackets, cross-heads on said rods, springs surrounding the rods and engaging at their lower ends with the brackets and at their upper ends with said Cross-heads, pins adapted to be engaged by the cross-heads to limit the downward movement of the step one of said rods having an upward extension, a lug on said extension designed for engaging the under side of the oar-platform sill, a footplate on said upward extension, and a spring' attached to the car-platform sill and engaged to the outer side by said upward extension.

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

GEORGE GRANT COMER.
