Specification of Letters Patent.

Application filed April 20, 1909. Serial No. 490,996.

, constructions and combinations of parts here .inafter described and claimed.

The object of the invention is to provide a step of the kind specified which, when not inuse, will be folded neatly and inconspicuously against the bottom of the fixed steps and which maybe easily moved into operative position from the platform of the car.

Referring to the drawings forming a part hereof: Figure l is a perspective view of a portion of a car provided with the'improve- .ment, showing the step in operative position; Fig. 2 is an end view, showing the step folded; Fig. 3 is'a transverse section of a portion of the car platform, showing the operating mechanism; Fig. 4 is a partial transverse section of the fixed steps, showing a detail of the folding mechanism; Fig. 5 is a plan view of the locking mechanism; Fig. 6 is a section on the line 66 of Fig. 5, looking in the direction of the arrows;

Y and Fig. 7 is a-perspective view of one of the step supporting brackets.

The embodiment of the invention shown in the drawings comprises a step 1, preferably of wood, and resting at each end upon a plurality of perforated ears 2 extending from the lower edge of the body portion of a bracket'3, which body portion is provided at approximately its center with a lug 4 extending outwardly and provided with an inclined transverse slot 5, and the ears traversed by bolts or screws for securing the ears to the step. A bar 8 has one of'its ends secured in the slot by means of a bolt or lag screw 9, and the bar is slidable in bearings 10 secured to the side plates 11 of the usual car steps, the upper end of the plate having an angular portion 12 for engaging the uppermost bearing to limit the downward movement of the bar with respect to the side and that the said step corresponds in shape and'fdimensions-with the other steps, and is finished in like manner. V,

A plate 13 is secured transversely of the auxiliary step by any suitable means, as, for instance, bolts 13 and the inner end of the plate'projects beyond the edge of the step and is provided with spaced ears 14. A rod 15 has one of its ends pivoted between the ears, and the other end is provided with spaced cars 16, between which is pivoted the 1 outer end of a rigid arm 17, extending from the center of a'rock shaft 18, journaled in arms 19, connected to the side plates 11. Each of the arms 19 is secured to the adjacent plate by screws 20 and one of the arms is formed in two sections, one 20 of which is of greater thickness than the other and is longitudinally recessed, as at 21, to receive the other, the sections being secured together by screws 22. The outer section 20*is provided with a split bearing 23, Whose sections are secured together by bolts 24.

The purpose of the above construction is to permit the insertion and removal of the rock shaft, the sections of the split bearing beingloosened to permit the introduction or removal of the shaft, and the end of the shaft adjacent to the car body 25 is threaded and engaged by a nut 26, while the-opposite end is provided with an integral arm or crank 27. The arm 27 is provided with spaced ears 28, between which is pivoted one end of a link 29, [the link extending upwardly through an opening 30 in the platform 31 of the car, and being provided at its upper end" with a pair of spaced ears'32, for a purpose to be presently described. I

A lever 33 is pivoted to an ear 34 on abracket 35, secured to the car body, as at 36, the lever having spaced cars 37, between which is received the ear 33, and adjacent to the point of pivotal connection the lever is provided with-an angular portion 38, which is received between theears 32 of the link and connected therewith by a rivet or bolt 39. The angular portion 38 is formed, in the present instance, by bending the lever at an angle to the body portion, and return bending it at an angle to the first. bend, and the free end of-the lever is provided with a grip 40 for convenience in manipulating the same. I I

It will be evident from the description that. when the free end of the lever is elevated the rock shaft will be oscillated to in closed position, the said means being arswing the arm 17, and through the connection of the rod '15 therewith the auxiliary step will be pushed downwardly and outwardly into the position shown in Fig. 1, the step being guided andlimited in its move ment by the bar 8. i p

A means is provided for locking the -step ranged upon the platform 31 and engaging the link 29. The said means consists of a plate 41, shown in Figs- 3, 5 and 6 in detail, secured to the platform by screws 42,and the sides of the plate are each provided with a flange 43 overlying the plate. A-pair' of levers 44 and 45 is pivoted on the plate, as at 46, the lever 45 being pivoted directly there to by itsinner end, while the lever 44 is provided with a lateral lug engaged by thepivot 46; The lever 44 extends beyond the plate at both ends, and the one end 47 'is bent at an angle to the' lever proper and is provided with a cross head 48. The. oppositeend of the lever is provided with a recessed jaw '49 for receiving the link, and the free end of the lever 45 is provided with a similar jaw .50, coiiperating with the jaw 49. A spring 51 is connected by one end with the lever 44 and by the other with a pi1152 on the plate,

and acts to retain the. jaws clamped on the link. By moving the end 47 of the lever 44 into the position-shown in doted lines in Fig.

. 5, the jaws are released from the link, which a and a strap 54 is'arranged'across the plate,

the ends of the strap being bent at an anglethereto for engaging the outer edges of the is then free to move longitudinally. The

lever is recessed, as at 53, in order that it may move under the overlying flange,

sides of the plate. The link 29 is provided with an integral collar 55 which engages the lower faces of the jaws when they are closed, and the engagement of the said parts, rather than the grinning action of the jaws, is rein full lines in Fig. 1, thus pushing the step into the position shown in the latter figure. After the step has served its purpose the leveris swung in the reverse direction, which elevates the step into the position shown in Fig. 2, the step fitting neatly against the lowest fixed step, so that-it will hardly be noticeable. The side plates 11 of the fixedsteps are extended below the lowest fixed step,- as at 56, and are recessed, asat 57 to receive the'lugs 4. the auxillary step being received between the said ends when in elevated' position.

- It will be observed from an inspection of the fixed steps thereof, of an auxiliary step "Fig. 3 that the lower face of the collar 55 is beveled, as at,58, while the u perface is flat, so that the beveled face-wil spread thelevers when the linkv moves downwardly. The jaws permit the linkto move freely in a downward direction, but prevent its upward movement.

It will be evident from the description that the auxiliary step is simple in construction and not liable to get out of order easily, since it is devoid of complicated parts, and. that it may be applied to existing cars without any extensive changes in the 'cars being necessary.
