I Specification of Letters Patent.

Application filed December 24, 1914. Serial No. 8781,912.

lllinois, have invented certain new and useful Improvements in Folding Car-Steps, of which the fol.i owing is a specification.

This invention relates to improvements in folding car steps for railway cars, has for its object to produce an auxiliaryt step of this class hinged to the lower end of a stepway of a car platform and connected to and operated by a trap door which normally closes the upper end of the stepway and which is hinged'to the door of the vestibule of the car.

The invention is simple in .-construction, positive and elicent in operation.

With the foregoing and other objects in view the invention consists in the combination and arrangement of parts to be hereinafter fully described in the following specification, pointed out in the claims and illustrated in the accompanying drawings which form a part of said specification and in which- Figure 1 is an end view of a vestibuled railway car with the platform and stepway in section and provided with my improved folding step. Fig. 2 is a similarview with the vestibule door open. Fig. 3 is a side view of Fig. 2. Fig. 4 is-a plan" view of the rod socket employed. Fig. 5 is a fragmentary View of the rod showing its enlarged end. Fig. 6 is a side elevation, of one section of the socket shown in Fig. 4. Fig. 7 is a front view of Fig. 6. Fig. 8 is a View of the opposite end of the rod of Fig. 5 and its connections. Fig. 9 is a plan view of Fig. 8. Fig. 1Y0 is an end view of the auxiliary step. Fig. 11 is a section taken on line 11-11 of Fig. 10. Fig. 12 is an enlarged fragmentary portion of the slotted trap door-and connecpions. Fig. 13 is a vertical section through Like reference characters indicate corresponding parts throughout the several views.

rllhe reference numeral 1 designates the end wall of a vestibuled railway car, 2 the platform, 3 the stepway and 4y the door of the vestibule. To the door 4 a trap door 5 slotted longitudinally at 5a is hinged as at 6 so that it may be moved through an arc of approximately 90 degrees when the door 4 is closed and whenV the trap door is in closed position it closes the upper end of .the stepway. rllhetrap door is provided with a hand ring 7 by means of which it may be moved. A 2-piece plate 8 is fastened to a T-block 8a that rides in the slotted portion 5a of trap door 5 and the same carries a 2--piece bearing 9 which serves as a cup for the enlarged end 10 of a pitman 11, the cup and end 10 forming a ball and socket joint. The opposite end of the pitman 11 -is fastened by means of a clamp 12 toa 2-piece socket 13 adapted to releasably retain the enlarged end 14 of a gooseneck lever 15 which is pivotally hung at 16 in a bearing 17 secured to a riser and one of the steps of the stepway; the other end of said gooseneck lever pivotally carries a pitman 18 which terminally carries a'pivot 19 that is slidably disposed in the cam-recessed portion 20, 20b of auxiliary step 21, said step being hinged as at 22 to the lower end of the stepway. A. plate 21a secured as at 21b tothe auxiliary step is slotted at 20c and formed with a shoulder 20d. The recess 20 is slightly curved while the recess 20b is greatly curved. To/the plate 21a a spring 23 is secured as at 24E.- and said spring passes between guide pint-"25 and `extends as at 26, 27 across the central channel 20c near one end of the same. Another spring 28 secured to plate 21a at 29 passes between 'guide pins 3 0 and extends across the channel 20 near its opposite end.

Operation ln Fig. 1 of the drawingsthe full lines show the step and connections in closed or. inoperative position. rll`he vestibule door is closed and the trap door down. 'l[o throw the step into operative position raten-tea api-.ia rais.

(shown in dotted lines) the trap door is raised by the hand ring'7 until 4it stands against the back of the door 4 and this operation will move the gooseneck lever into the position shown in dotted lines and the pitman 18 will press the pin 19 against the slottedportion of the plate 21a but the pin 19 coming in contact with the spring 28 will not be permitted to pass through the portion 20 but will be deflected into the slotted portion 20b and as it. rides through this porlever 18 will pull upon the pivot 19 which.

must travel back to its original position through the'channeled portion 20, as contact with spring 23 will not permit it to do otherwise., thus moving the step 2l back upon its hinge. 22 into inoperative position.

What isclaimed is 1. The combination with the stepway and door of a vestibulod railway coach, of a trap door hingedto said door and adapted when closed to close said stepway, an auxiliary step hinged to the lower step of said step- Way and connection between said door, step- Way and auxiliary step whereby movement of said door will operate to move said auxiliary step and to osition it' operatively as said door is openeci).

2. The combination with the stepway and door of a vestibuled railway coach, of a trap door hinged-to said door and adapted when closed to close said stepway, a pitman connected to said door, a goose neck lever swiveled to said pitman and pivotally connected to said stepway, another, pitman pivotall connected to said gooseneck lever, an auXi iary -step hinged to the last step in said stepway, a slotted plate secured to said auxiliary step and. a pivot carried by said last named pitman and disposed in the slotted. portion o said plate whereby the same may be moved into and out of operative"position.

3. The combination with the stepway and door of a yestibuled railwaypoach, of a trap door'hingefl to said door and adapted when closed to close said stepway, a pitman connec-ted to said door, agooseneck lever Vposed in the slotted portion of said plate and springs secured to said plate and extending across one end of each of said slots to deflect said pivot into the opposite slot.

In testimony that I claim the foregoing as my own I have hereto aflixed my signa.- ture in the presence of two subscribing witnesses.
