IMPROVEMENT IN FCLDING DOUBLE-STEPS FIOR CARRIAGES.
Specification forming part of Letters Patent No. 127,707,1dated June 11, 1872 antedated May 22, 1872.
To all whom it may concern:
Be it known that I, JAMns ,PENDERGASL of New Haven, in the county of New Haven and State of Connecticut, have invented a new Improvement in Folding Carriage-Step; and I do hereby declare the following, when taken in connection with the accompanying drawing and the letters of reference marked thereon,
tobe a full, clear, and exact description of the' same, and which said drawing constitutes part of this specification, and represents, in-
Figure l, a front view; Fig. 2, a side view; and in Fig. 3, a vertical central section, showing the steps open.
This invention relates to an improvement in folding-steps for carriages, especially designed for that class in which the steps are automatically opened or closed with the door, the object being the arrangement of two steps combined, so as to operate together. The invention consists in the arrangement of two steps, one above the other, in a suitable support, and constructed with an arm on each step, which two arms are joined by a connecting-rod, to cause the movement of one of the steps to communicate a similar movement to the other.
A is the frame, xed to the carriage in the usual manner. B is the lower, and C the upper, step, pivoted to the frame, respectively, at b and c, and of such relative length of plate that when both are closed they cover the front of the frame, as seen in Figs. 1 and 2. Each step is provided with an arm, a, and a rod, D, extending from one arm to the other, to con- ,nect the two so that as one step is moved the other necessarily moves with it as, for instance, the steps being closed, aperson taking hold of one ofthe steps for the purpose of lowering or opening, and drawing that step from the frame, will, at the same time, by the connection D, communicate a like movement to the other step, a suitable stop being arranged to arrest the movement of the steps when they are lowered to the required level. The mechanism by which the movement ofthe door` may operate the steps is connected to the rod I), or to either of the steps, in the usual manner.
I claim as my invention- The arrangement of the two steps B C, when they are attached together and both fold in the same plane with the frame A, substantially as described.
