To all whom it may concern.- I

Be it known that I, ARTHUR J. BARBER,a' citizen of the United States, residing at Sodus, in the county of Wayne and State of New York, have invented new and useful Improvements ing is a specification. Y My invention relates to improvements in folding steps for cars; and it has for its obof treads and risers, which, when folded, will form a continuation of the car-platform.

A further object is to provide steps of the character named which when folded will form a continuation of the car-platform, with a foot- The invention consists in so pivoting the treads and risers of the steps to operating arms .and bars that when folded they will be adjusted edge to edge and will form a continuation or extension of the platform, with the exception of the lowest tread, which will assume a vertical position at the outer edge of the said extension, and thus constitute a guard to prevent persons from falling from the plat,

The invention consists, further,in certain novel details of construction, hereinafter more panying drawings, 'wherein- V Figure 1 is a perspective view of the end of a car the platform of which is provided with my improved steps, those on one side being in the lowered or operative position, while those on the other side are in the raised or horizontalposition. Fig. 2is a section of thesame. Fig. 3 is a side view to show the operating mechanism.

Referring by letter to the drawings, A designates the platform, having the openings B B at each end, in which the steps operate, it being my desire to bring the steps in both the lowered and raised positions within the line of the outside'of the car.

Grepresents a frame which depends from the, platform near the inner end of each opening B, and it comprisesthe vertical bars 0 cand the-horizontal bar 0, which connects the lower endsof the vertical bars. This frame is braced by fthinclined braces D D, which depend the length of the car, and F F representswing- 5 5 ing arms which are mounted at their upper ends on this rod. Similar arms,'G G, are pivoted at their upper ends to the sides of the openings BB at a distance from the upper. ends of the arms F Fequal to the width of a tread of the proposed steps. The arms G are about twice the length of the arms F, andtheir centers are connectedto the lower ends of the said arms Fby the links HH. 7 f

It will be evident that if the upper ends of the arms F and G are pivoted at the same level and the ends of the links H are com nected thereto at equal distances from their pivots the said links will be horizontal in'any position which the swinging arms may assume. The upper edges of the links are provided withhorizontal inward-extending'flanges h h, for a purpose hereinafter explained.

I I represent swinging arms, which are pivoted at one end to the vertical bars a 0 near their upper ends, and they are divided at their other ends to formthe forks K K. The arms k k, which comprise the said forks, are connected at their lower ends by the bars L, which have inward-extending flanges Z, for a purpose to be hereinafter explained.

The lower ends of the arms G G are provided with the outward-extending angle-arms M M, and the extremities of the latter are connected to intermediate points of the arms I I by means of the links N N, which have in= ward-extending flanges n n. It will now be. seen that when the arms F and G are in their vertical position the lower end of the arm G will bear against the horizontal bar 0', and the links Hwill be horizontal, the armsI I will be inclined at-an angle of about forty=five degrees, and the bars L at the lower ends of? the arms I will be horizontal, as also will be thelinks N N. When the arms F and Gare swung up to their horizontal position, the links H will still be horizontal. As before described, the link N is connected at the outer end to aninten mediate point of the arm I, and at a point near the inner end'to the extremity of the angle -too arm M, which is on the lower end of the arm G. The upper pivoted ends of the arms G and I are in the same vertical line; but the ends of the arms G are above those of the arms I, whereas the distance from the pivoted end of the arm G to the point where the link is pivoted thereto is about the same as the distance from the pivoted end of the arm Ito the point where the other end of the said link is pivoted thereto. Therefore, as the lower ends of the said arms are swung upward, the outer ends of the links N are drawn upward and inward by the arms I, and the inner ends of the said links are swung downward and outward by the arms G, thereby causing the links to turn over and assume a position the reverse of that previously occupied. WVhen thelinks N N are in the reversed position described, the arms I I are inclined upward at an angle of about forty-five degrees, and therefore the bars L L are vertical.

0 represents the top tread, which is secured to the horizontal flanges h on the links H.

P represents thesecond tread,which is simi lar to the tread O, and is secured to the flanges n on thelinks N; and Q represents the bottom tread, which is secured to the flanges Z on the bars L.

0 represents the top riser, which is secured at the ends to the swinging arms F F, and P represents a riser which is secured to the arms G G below the point where the ends of the links H are pivoted thereto. The rear edge of the tread 0 projects ashortdistancebeyond the ends of the links H, and therefore when the said links assume their horizontal position in the closed position of the step the rear edge of the said tread will exactly meet the front edge of the riser O, which is brought to the horizontal position by the armsF F, and their upper surfaces will be flush with each other and with the platform A. (See Fig. 1.) When the steps are folded, the links N are (as before described) turned over or reversed,'and therefore the tread P, which is secured thereto, will be similarly reversed and will fold over the riser P, so that its previous front edge will be brought in contact with the front edge of the tread 0. Thus the previous'under side of the tread P will be flush with the upper side of the tread O, and the riser P will be concealed under the tread P. The present outer (previous inner) edge of the tread P will fold up against the lower (previous inner) edge of the lowest tread, Q, and as the latteris in a vertical position it will form afoot-guard for theside of the platform. The arm F on one side of the steps (preferably the side toward the body of the car) is provided on the rear side with an angular bracket, F, comprising the converging barsff, which are connected together at their rear ends and are attachedat the opposite ends to the extremities of the arms F.

The arm G is provided on its rear side at the upper end with the angular bracket G,

and the bars g g, comprising the same, are connected at their rear ends, and are attached at their opposite ends to the arm G respectively at its upper end and at its central point. The bar g of the said bracket is extended beyond the arm G to form the handle B. It will be seen that the handle R and the bar 9 constitute a lever,which is pivoted at the same point as the upper end of the swinging arm G.

S represents a link,which is attached at its opposite ends to the apexes of the angular brackets G and F, respemely.

T represents a bracket which is secured to the platform A, and. it is provided with a notch, U, to receive and engage the handle when the latter is turned so as to close the steps. It will be seen that when the steps are raised or closed the handle'is drawn inward at the upper end, and it is preferably so arranged that when it comes in line with the notchU it willautomatically spring thereinto.

From the foregoing description it will be readily seen that by a mere swing of the bandle R the steps may be either opened (with the treads and risers in their proper relative positions to allow persons to enter the car)'or closed, (with the said treads and risers drawn up to form an extension of the platform, with a guard at its outer edge.) Thus the openings B B in the platform are closed, thereby enlarging the available space, and preventing persons from falling or being thrown from the platform while passing from one car to the next.

A gate may be hung to the corner of the car, to extend over the foot guard, and thus prevent all possibility of accident. By thus drawing up the steps persons are prevented from jumping on or off the platform while the cars are in motion.

It will be seen that if necessary the number of treads and risers in the steps may be increased, it being only necessary to'duplicate certain parts of the operating device, and also the number of treads may be reduced.
