Definitions

• This invention consists of an auxiliary step particularly adapted for use in connection with the usual steps of a Pullman or ordinary passenger car and designed to be lowered for use when the car is run intoa depot or alongside an alighting-platform to admit of greater ease in passing into and out of the car.
• the present disadvantages arise from the fact that the lowermost step of the average passengercoach is too high for one to step to or from without difficulty, stools being often used to facilitate the above; and it is therefore an object of the invention to obviate the foregoing by the provision of the'auxiliary step mentioned and novel operating means for the same.
• FIG. 1 is a perspective view showing the invention applied.
• Fig. 2 is a vertical sec tional view showing the steps of the usual construction of railway-coach, an auxiliary step being shown adjusted in a lowermost position as when in use.
• Fig. 3 isarearelevation bringing out more clearly the mounting of the auxiliary step upon the main steps of the coach.
• Fig. 4 is a perspective view showing a portion of the steps, bringingout more clearly the arrangement of the spring which cooperates with the operating-lever.
• the rigid steps of the car are indicated at 1, and said steps are of any common approved construction.
• the auxiliary step is designated 2, and this step when out of use is normally held in a position just beneath the lowermost of the steps 1.
• Special means are provided for supporting and operating the step 2, said step being secured to guide-rods 8, extending upwardly therefrom and movable in brackets or guide members 4, substantially attached to the rear sides of adjacent steps 1.
• the step 2 is directed in its movement primarily by the rods 3, being actuated, however, by means of a lever 5, mounted upon a crank 6.
• the crank 6 is mounted in a bearing 7, located in rear of the uppermost step, and one end of the crank 6 is projected through a side of said step, so that the lever 5 may be readily mounted thereon in a convenient position.
• An arm 8 of the crank 6 is connected with a rigid bar 9, projected upwardly from the step 2 and extended therefrom at a point preferably about intermediate the guide-rods
• the bar 9 is suitably attached to the step 2, and the upper end of the bar is connected with the arm 8 by means of a link 10.
• the step 2 When in its uppermost position, the step 2 is just beneath the lowermost of the steps 1, as mentioned above, and the outer edge of the step 2 is about flush with the step 1 aforesaid. sition by means of a curved spring 12, which projects upwardly from the uppermost step 1 and engages beneath a lug 13, projected lat erally from the lever 5. An interlockingconnection is established between the spring 12 I and the lug 13 by deflectingsaid springsomewhat adjacent its front end, so that when the lever 5 is so disposed as to force the lug 1 3 into the deflected portion of the spring (inch- The step 2 is held in its uppermost po-' cated at 14:) the step 2is virtually locked from downward movement.
• the crank-arm 8 By forcing the lever 5 rearwardly, however, the crank-arm 8 is moved downwardly, actuating the step 2 in the same direction, and when said crank-arm reaches an approximately vertical position, engaging the rear side of the uppermost step 1, the step 2 will be rigidly held in a position sufficiently near the depot or alightingplatform as to admit of stepping into and out of the car without difiiculty.
• One of the guide members 4 is preferably used for operation with the bar 9 also. It will be noted that the device, as hereinbefore described, is very simple and may be operated by the conductor or porter of the car as the train enters and leaves a depot or the like.
• an auxiliary step normally disposed beneath the lowermost of said steps, a plurality of guide members attached to the rear sides of the first-mentioned steps, a plurality of guiderods projected upwardly from the auxiliary step and cooperating with the guide members aforesaid, a bar extended upwardly from the auxiliary step, a crank mounted in rear of one of the first-mentioned steps and having its arm projected rearwardly therefrom, a link connection between the crank-arm and the bar of the auxiliary step, a lever mounted upon the crank aforesaid for connection thereof, a lug projecting laterally from the lever, and a curved spring extending upwardly from the uppermost step and provided in its length with a deflected portion adapted to receive the lug of the lever to thereby interlock therewith.
