UNITED STATES PATENT; OFFICE JOHN WALTER, or NASHVILLE, TENNESSEE. I

r CAR-ROOF.

SPECIFICATION forming part of Letters Patent N o.'286,877, dated October 16, 1883.

Application filed July 27, 1883. (No model.)

[0 mil whom it may concern.-

Be it known that I, J oHN' WALTER, of Nash= ville, in the county of Davidson and State of Tennessee, have invented a new and useful Improvement in (Jar-Roofs; and I do hereby deelare'that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming part of this specification, in which- Figure 1 is a partial plan View of a car=roof with one of the plates removed and a portion of the hand-rail and running-board broken away. Fig. 2 is a cross-section through the line 00 0c of Fig. 1, and Fig. 3 is an edge view of the roof from the side of the'car.

My invention relates to roofs for railwaycars; and its object is toprovide a readily deremoved or applied in part or whole, and also to afford greater security to the brakeman in running along the top of the car, as well as to provide an efficient means for ventilating the car. These objects are attained in the construction and arrangement of parts which I will now proceed to describe.

In the drawings, A represents the sheathing or top casing of the car-body, which forms the foundation for the roof, and has a slight inclination or slope upon each side from the middle line of the car. The roof is composed of sheet-metal plates B and B, arranged alterear-roof to the sides thereof. The two plates B and B are of different construction, and are adapted, when placed together, toform a watertight joint. The two edges of any one plate are exactly alike. The plates B are screwed or nailed to the sheathing a distance apart equal to the width of plates B, and the latter are then slid longitudinally upon and over the edges of the plates B, to form the necessary The plates B have their longitudinal edges bent (see Fig. 3) first upwardly and inwardly toward the plate, to form the ledge or flange a, then back upon the flange and downwardly, and then up to form the groove or trough b, and then down again and horizontally at g. The plates B have their longitudinal edges bent upwardly andoutwardl'y from the plate at an obtuse angle at 0, then horizontally at d, and-then downwardly and inwardly toward the plate at e. In fitting the plates, those marked B are corrugations on each side, no water can work in at this joint, and if any does get in it passes out the drain-trough b.

At the upper ends of the plates B the upturned flanges h are disconnected on opposite sides of the middle of the. car, so that said plates may be drawn apart from each other in taking the roof off the car, but the upper flanges, z', of the plates B are turned over each other to form a connection or tie across the apex of the roof. At the lower edges of both series of plates aredownwardlyproj ecting flanges j and la, which are nailed or screwed to the bargeboards or sides of the car.

Extending along the middle line of the car is the running-board O, which has'supports Z on each side of the middle, which rest upon the flat partof the roof-plates. In the middle of this running-board, on the under side, is a ventilating-groove, m, which communicates with'holes in the top of the car through the spaces between the disconnected flanges h of the plates B, thus securing the ventilation of the car.

In sleety weather, or when the car-roof is covered with ice, the passing of the brakemen over the top of the car is attended with great danger of slipping off. To prevent this I provide a hand-rail, E, which extends alongside of the running-board, and is sustained in brackets F five or six inches above the roof of the car. These brackets are screwed or riveted tothe sliding plates B, an elastic packing being interposed between them and the plate to close the hole against leakage. These brackets are also bolted horizontally through the running-board, as shown at m". The handrail is contained in sleeves or sockets of the brackets, and maybe removed tl1erefron1,When the plates are to be taken ofl, by slipping said rail endwise through said sleeves. For forming this hand-rail, sections of gas-pipe are well adapted, and the ends may be joined to form a union of the sections by a serew-eoupling at the sleeves of the brackets.

Having thus described my invention, What I claim as new is 1. A roof composed of plates 13 and B, arranged alternately, the plate 13 being formed with longitudinal flange a and groove b at each of its edges and screwed to the sheathing, and the plate B having overlapping bend a d and hooked edge 0, adapted to slide upon the edge of other plate and cover it, substantially as describe;

and for the purpose described.
