Abstract: 8412. Beach, R. H. April 6, 1910, [Convention date]. Tramcars; sides, roofs, partitions, and framing; hand - grips and s a f e t y guards.- Car bodies, especially street car s driven by electric storage batteries, are built up about a lattice girder framework in such a manner that all the parts cooperate to stiffen t h e structure in all directions so that lighter materials may be used. In the form shown, the body is built upon two light lattice girders 1 of angleiron which form the sole support for the seats, the spaces within the girders beiog utilized for storage batteries 90. Wire screens 91 extend from the seats to the floor and partially conceal the batteries. The girders are connected together by light beams 3, which also support two light longitudinal sills 2. The side posts 20 of the car are secured at their lower ends to the sills and cross-beams, and near the upper corners of the girders 1 to longitudinal strips 6, the strips and side posts being connected to the girders 1 by angleirons 7. Longitudinal strips 8, 9, 10, 11, 12, 13 also stay the posts together longitudinally. The upper ends of the side posts are stayed laterally by the roof, which consists of an eccentric arch having inner and outer sections 30, 31 kept in shape by light carlines 35 and stayed longitudinally by a central strip and two strips arranged in the position shown at 32. The strips 10, 11, 12, 13 secure the roof to the side posts. The roof is constructed of veneer, metal, leather, or matched wood. The end bulkheads 14 are bolted to the upper and lower edges of the girders 1, and are stayed at their upper ends, which are carved to conform to the roof, by the longitudinal strips in the roof. Secured to the roof beneath the strips 32 are brackets 50 which receive the upper ends of vertical grab rods 60, the lower ends of which are secured in extensions 70 fixed to the girders 1. These rods act as additional stays for the roof, and to render them adjustable, their connexions between the brackets 50 and extensions 70 may be by reversely threaded screws. The brackets 50 have arms 58 supporting a guide 55 which surrounds the grab-rods 60 and carries extensions 56 adapted to take the reversely threaded ends of horizontal grab-rods 65. Eyes 59 are formed in the arms 58 to take the signal cords. Extensions 53 are also provided on the brackets for lamps 54, the grab-rods 60 serving as conduits for the electriclight wires. The ends of the rods 55 are secured to brackets 40 on the bulkheads 14. The windows slide in grooves 21, 22, of the shape shown, formed in the side posts. They rest, when raised, upon hinged plates 24 which are turned up into recesses 23 when it is desired to lower the windows. These arrangements enable the window to commence sliding in the same plane that it occupies when closed, thereby saving space. Doors for passenger vehicles.-The Specification as open to inspection under Section 91 (3) (a) comprises also doors consisting of two leaves 100, 101 rendered self-closing by means of spring hinges between the leaves, the outer corner being supported in such a manner that it will not bind should the end platform become distorted. The upper corner of the leaf 101 is supported through a spring 115 from a roller 112 running on a rail 113. Catches 104, 105 secure the door in its closed and open positions. This subject - matter does not appear in the Specification as accepted.
