FOLDING CAR STEP AND DOOR.

Specification of Letters Patent.

Patented Feb. 11, 1913.

Application filed October 28, 1912. Serial No. 728,142.

To all whom 15 may concern:

Be it known that I, AREY V. VVINEGARDEN, a citizen of the United States, residing at Eldorado, in the county of Butler and State of Kansas, have invented a new and useful Folding Car Step and Door, of which the following is a specification.

My invention relates to improvements in railway car steps, and has for its object to provide the fixed steps of the car with a folding step, in combination with a door leading to the steps, and operating means for simultaneously lowering or opening the folding step and opening the door or closing the folding step and shutting the door, means being provided for positively locking the folding step and door in a closed position and also for holding them both in an open position.

The invent-ion consists in certain novel features of construction and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that various changes in the form, proportion, size and minor details of construction may be made without departing from the spirit or sacrificing any of the advantages of the invention.

In the accompanying drawings :-Figure 1 is a transverse sectional view taken through the end sill of the platform of a railroad coach showing the outer side of the fixed steps with my invention applied thereto, the parts being in a closed position. Fig. 2 is a similar view with the parts shown in the open position. Fig. 3 is a transverse sectional View taken through the platform close to the end of the body of the car showing the inner side of the fixed steps with the invention applied thereto and the parts in an open position. Fig. 4 is a longitudinal sectional view through the platform showing the back of the fixed steps with the invention applied thereto, the parts being shown in an open position. Fig. 5 is a horizontal sectional View taken on the line 55 of Fig. 4 but showing the parts in a closed position. Fig. 6 is a fragmentary view of a portion of the fixed steps and platform showing the trap door in a closed position. Fig. 7 is a perspective view of the operating lever, rock shaft and associated parts. Fig.

8 is a perspective view of the member which serves as an abutment for the hand lever.

Referring to the drawings, which illustrate the preferred embodiment of my invention, 10 designates the platform of a railroad coach provided with the usual passageway or exit leading to the fixed steps 12. Near the front or outer edge of the bottom of the lower step of the fixed flight of steps is hinged the riser 13 of a folding step 1 1. The riser 13 and the tread 15 of the folding step are hinged together at their meeting edges so as to fold flat one against the other beneath the lower fixed step. Pivotally connected to the tread 15, near its outer or front edge, is a link 16, and to the rear or lower end of the riser 13, is connected the end of a second link 17 having a slot ends of the links is the free end of a lever 21. This lever is fixed to one end of a transversely-arranged rock shaft 22, which is arranged in rear of and extends entirely across and slightly beyond the sides of the fixed step and is journaled in bearings formed by strap irons 23 secured to the underside of the fixed steps. Connected to the other end of the lever 21 is the lower end of a diagonally-disposed link 24. The upper or other end of the link is connected to the lower end of a normally vertically-disposed hand lever 25. The lever 25 is pivoted at 26 in a slot 27 formed in the inner face of the transverse end sill of the platform 10, so that its lower end projects below the platform. The hand lever extends up some distance above the platform and terminates at its upper end in a suitable grip or handle 29. The stroke of the hand lever is limited in its forward movement by the depending stop 30 formed on a plate 31 attached to the underside of the car sill.

The link 16 connected to the end of the tread 15 is provided at an intermediate point with a shoulder 32. Adapted to cooperate with the shoulder 32 is an angular latch lever 33, which extends up through the slot 27 of the platform and is pivoted at 34 within said slot, and has its lower end provided in rear of and above the pivot 20 which connects the lever 21 with the links 16 and 17, thereby holding the steps locked in both positions. I

The rock shaft 22 has secured to its end at the inner side of the steps a bell crank lever 40. The long orupper arm 41 of the bell crank lever is connected to the pivot 20 connecting the upper ends of another set of links 16 and 17, which are exactly similar to the corresponding links at the outer side of the steps, except that the shoulder 32 is omitted from the link 16. Connected to the free end of the lower or short arm 42 of the bell crank lever -is the lower end of a vertically-disposed arm 43, the upper end of which extends up through a hole in the platform 10 close to the passageway leading to the steps. The upper end of the arm 43 is provided with teeth constituting a rack 45.

Adapted to normally close the passageway in the platform is a trap door 46, which is hinged at the inner side of the passageway and is designed when closed to have its upper face flush with the top of the platform. The trap door is provided along its inner edge with a pintle rod 47 secured by means of strap irons 48, the ends of the pintle rod passing through eyes 49 connected to the platform. Secured to the pintle rod 47 is a segment 50 which meshes with the rack carried by the arm 43.

When it is desired to lower the folding step 14 and open the door 46 leading to the steps, the trainman places his foot upon the treadle 38 of the latch lever 33, thus raising the lip 37 out of engagement with shoulder 32 on the link, and then pushes the lever 25 from the vertical position to the inclined position shown in Figs. 2 and 3, whereupon the link 24lifts the inner end of the lever 21, and forces the links 16 and 17 downwardly thereby unfolding the folding step by forcing the riser 13 to a vertical position and the tread 15 to a horizontal position. Through 38 the lip 37 will descend assuming the position shown in Fig. 2, thus locking the folding step and trap door in an open position. Then the vestibule door is opened swinging in front of the trap door, so that it is out of the way. NVhen it is desired to raise the folding step and lower or close the trap door, the vestibule door is first closed and the trainman again presses his foot on the treadle raising the lip 37 to the position shown in dotted lines in Fig. 2, when the lever and the attached parts can be pulled back to the vertical position shown in Fig. 1.

From the foregoing it will be apparent that I have produced an exceedingly simple and effective device which can be easily and quickly operated to open and close the folding step and trap door simultaneously. It is also evident that the folding step can be used without the door and its operating connections, and that if desired the folding step could be operated by employing one set of links 16 and 17, though the duplicate set is the best construction.
