MAIL-CAR.

SPEG1FIGATION forming part of LettersiPatent N 0. 709,894, dated September 30, 1902.

Application filed May 12. 1902.

provements in Mail-Cars, of which the following is a specification.

My invention relates particularly to the construction and arrangement of railway-cars specially adapted for carrying and protecting mail-matter, though the principles involved in said invention are equally applicable in a car for carrying express-matter, money, or

other valuables. v

- The special objects of my invention are to provide a car of the class stated which will be fireproof and of such shape and strength as to be proof against demolition from collisions or telescoping; also, to provide a car which cannot be destroyed by the use of ex-.

plosives in the ordiuary manner and in which the lives of the persons in the car will be fully protected.

Having these and other objects of general utility in view, I have invented the railway mail-car'shown in the accompanying drawings, which form a part of this application, and in which- Figure 1 is a side elevation of a car embodying my invention. of the car with a portion of the roof removed. Fig. 3 is an end elevation with a portion of the end removed. Fig. 4 is a-front' elevation of the sliding door, which forms an element of my invention. Fig. 5 is a vertical section through the door on the line Z m of'Fig. 4'. Fig. 6 is a bottom plan view of the door. Fig. 7 is a section through the side walls and a portion of the car-floor. Fig. 8 is a crosssection on the line X Y of Fig. 7. v Fig. 9 is an enlarged detail of Fig. 8. Fig. 10 is a detail in section, showing the nnanner of securing the floor-plates to the car-framing.

w Referring to the drawings in detail, A A represent the outside main girders, formed of angle-irons, the end portions of which are bent on a curve inwardly and secured together at the draw-bars. Extending transversely between the girders are cross-beams B, and extending longitudinally of, the car are intermediate beams B, all of said beams being suitably secured to .the girders A.-

Fig. 2 is a top plan view Serial No. 107,051. (No model.)

Channel-bars O, are secured at each end of the car-floor frame and furnish suitable bearings and braces forthe draw-bars D.

E represents the car axles, and F one of the frame-ribs, which is formed of T-iron bent rounding at its middle portion and having its ends suitably secured to the girders. To these ribs are secured the sheet-metal plates H, which form the sheathing or side and roof wallsof the car.

G is an angle-bar which extends from end to end of the car and forms a meeting bar for the sheathing-plates at the ends and on the roof. The outer wall or sheathingU and the inner wall or lining V are made up of a plurality of sheet-metal plates H, which are riveted together at their contiguous edges, so as to form tight joints. A space is preferably left between the lining and the sheathing in which may be placed an interlining of asbestos or other suitable fireproofing material.

I represents my improved car-door, which forms an important feature of myinvention. This door may be placed in both sides of the car and also in the partition k, with which I maysubdivide the car into two compartments,

it desired. This door is constructed of two 5 metal plates secured together with spacers T therebetween and riveted to a square metal barf, which extends along the edges of the plates and is bent to conform to the shape of the door. At the center of the door and on its inner side is a hand-wheel K, which is 'mounted on asuitable spindle secured in the door, said spindle also carrying a two-arm lever L, which is positioned between the two plates forming the door. To the ends 'of the lever are secured vertically-moving locking bolts or bars M .N, respectively, which project and slide in suitable openings in the bar f and when in locked position bear against the door-frame at the top and bottom of the doorway. Covering the lever and extending the width of the door is a plate at, which is secured in place by bolts and nuts, so that it can be readily removed if access to the lever is desired. Rollers O,mounted on pintles P, are arranged in the bottom of the door and travelin a grooved track Y, which extends across the threshold and serves as a ready means of sliding the door with little friction.

the top of the door on a pin R is mounted oller Q, which bears against the inside of a car and serves as an antifriction-bearing that point. Handles-S, secured to the in- .e of the door near its side edges, serve as lvenient means for moving the car-door. At each end of the car are ventilators J, of

y suitable construction, which serve not.

ly to permit the admission and exit of air, I: also serve as ports through which a gun revolver may be fired by those within the r. Within the car may be placed a fan-motor lriven by a belt 1', running on a pulley h, muted on the axle or journal E, thus imving the circulation ofthe air within the when the train is in motion.

I preferably divide the car into two comrtments by a partition g, which may be med of an iron grating or may be provided ah a grated opening it, thus facilitating the culation of the air throughout the entire In constructing my improved car I prefer secure the sheathing U to the flanges of a T-bars by rivets, as shown in Fig. 9, and opposite sides of the body of the T-bars I :ure by bolts X flat metal bars W, the outer gespf which bear against and hold in place alining V, also as shown in Fig. 9. Around a lower corner of the car I place an angler a, between which and the girder A is .ced the edges of the floor-plates b. On the per side of the horizontal arm of the angler is placed the floor-plates c, and said partsa riveted together, as shown in Fig. 10, thus iroughly and tightlysecuring them and proling an air-space d between the inner or per floor c and the outer or lower floor b,

ich space may be filled with a non-comstible, if desired. 3y forming the walls and floor of my improved car double 1 get a light and strong construction. By providing a car of the conical-end shape shown I avoid angles and broad surfaces, which would be easily damaged in case of a collision.

Through the use of the bar G, extending from end to end of the car and bent as shown, I am able to secure a water-tight joint between the contiguous edges of the plates which form the side walls and roof of the car.

Having thus described my invention, what Iclaim as new, and desire to obtain by Letters Patent, is

1. In a car, a frame composed of the girders A having their end portions bent as shown, longitudinal beams B arranged between the girders, transverse beams B, ribs F formed of T-bars, and the bar G, extending from end to end of the car and having its ends secured to the girders and bent as shown.

2. In a car, the ribs F composed of T-irons, sheet-metal plates riveted to the flanges of the bars and forming the sheathingof the car, the liniugVspaced from the sheathing,and means for securing the lining in place consisting of bars or plates bolted to the ribs and having their outer edges bearing against said lining, substantially in the manner shown.

3. In acar, girders A formed of angle-irons and having their ends bent as shown, an outer carfloor b resting on said girders, the sheathing U, angle-irons at extending "around the corner formed bythe junction of the bottom PATRICK J. FARRELL.
