16,090. Senter, R. T. July 9. Tramcars; ingress and egress of passengers, controlling; hand-grips.-A tramcar is provided with separate entrance and exit passageways on the front platform which also accommodates the motorman and conductor, the rear end of the car being enclosed and provided with an emergency door. The front platform is preferably at a lower level than the car floor and is divided into exit and entrance passageways by a rail 29. Rails 30, 31 enclose stations for the motorman and conductor. Folding doors 32, 33 and corresponding steps are operated separately or simultaneously by the motorman, and the rear exit door 23 and its step can be operated from the rear end of the car or from the conductor's station. A modification is described in which the conductor's station is placed between the entrance passageway and the near side of the car, the exit passage being adjacent to the motorman's station. In this modification the door controlling the entrance can be operated by either the motorman or the conductor. Two longitudinal seats 24, 25 are arranged near the front end of the car and another near the rear end. A seat 28 also extends part way around the rear end. A rail 91 is provided at the front of the car at a convenient height to be grasped by a person struck by the car Swing seats 37, 38 for the motorman and conductor are carried by brackets capable of sliding and turning on vertical pillars. The lower ends of the brackets have notches engaging corresponging projections on their supports to hold the seats in various positions. The remaining seats are cross seats. Steps ; doors, operating.-The doors 32, 33 are mounted on vertical shafts having arms connected by rods 45, 46, Fig. 6 to cranks on the ends of two concentric pillars 40, 41 provided with hand-levers 43, 44, Fig. 8, one above the other. To enable both levers to be moved together when required, a pin 47 on the lower lever is pushed through a hole in the upper lever by means of a lever 48 actuated by pressure on a pin 49. Hinged steps 50, 51 are connected up to the rods 45, 46 by means of rods 58, 56, levers 53, 54, and rods 57, 55 so that each step is operated wlth the corresponding door. The rear door is mounted on a vertical shaft 59, Fig. 4, having an arm 60 connected by a rod 61 to an arm 62 on a vertical shaft 63. The shaft 63 has a bellcrank 64 connected by a rod 65 to a vertical shaft 66, Fig. 1; at the conductor's station, and by a rod 67 to a bell-crank'68 which is connected by a rod 69 to shaft 72. A crank 79 on a shaft 63 is connected by a rod 78<a> to an arm on a spindle 76 carrying the step. The step consists of brackets 75 carring two treads, stops being provided on the brackets to impinge upon an angle-iron on the frame to limit their outward movement. When turned up, the lower tread rests against the car frame and the rest of the step lies beneath the car. Both of the shafts 66, 72 are squared to receive a detachable handle 73, the shaft 72 having a pivoted member adapted to be turned at right-angles to the shaft to retain the handle. To enable the handle to be adjusted, the square aperture is formed in a toothed, rotary element contained in the end of the lever. This element is normally locked to the lever by a spring pressed dog 82, Fig. 9, which can be withdrawn by pressing on a pin 80 acting through a bell-crank 81. The shaft 66 has a projection which is engaged by a removable pin to prevent the opening of the rear door 23.
