CAR CONSTRUCTION.

Specification of Letters Patent.

Patented Feb. 13,1912.

Application filed August 20, 1907. Serial No. 389,325.

Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain Improvement-s in Car Construction, of which the followingis a specification;

This invention relates to the construction largely of metal so as to be practically lire- 4 proof.

More particularly, the invention relates to a metallic sheathing for either or both the interior and exterior surfaces of the side walls of a car.

The object of the invention is to provide a metallic sheathing for various uses, as for instance in sheathing the side walls of cars, which consists of a plurality of similar sections, so that if one or more become damaged in any way, they can be readily withdrawn and new ones substituted, which is made of pressed sheet-metal sections capable of manufacture at comparatively small cost, in which the sections interlock so as to hold each other in proper relative position, and which presents an attractive appearance.

The sheathing constructed in accordance with the invention is of great utility as a lining for the interior and exterior of the sidewalls of cars, the truss-work for the side walls and for supporting the roof lying between the two sheathings. As thus used, the

- sheathings form a double metallic wall per-A mitting .comparatively little radiation of l with corresponding tongues and grooves- 'When the several sections are assembled, the tongue at one of the edges of each section enters thegroove at the edge of the adja-v cent ysection' to position the sections relaf" tively and the body-portions of the sections lie in substantially the same plane to form a .substantially unbroken wall.

the sections are so held that they are bowed slightly and, being flexed thus, vibrationis, to a very large extent, prevented.

The preferred embodiment of ythe invention is illustrated in the accompanying drawings in which- Figures l and 2 are sectional views through the side wall of a car, Fig. 3 is-an elevation of a portion of such wall, and Fig.

Preferably,

4 is a section through a length of the sheathing.

Referring to these drawings, 1, 2, 3 and et indicate sections of the sheathing, each formed of a strip of sheet-metal, preferably steel, pressed to provide a body-portion 5 and edge portions 6 and 7 at the lateral edges thereof turned at an angle of ninety degrees to the body-portion 5. At the extreme edges of the strips, flanges 8 may be provided as shown. In pressing the sections into form, a rounded groove 9 is formed in one of the edge portions, preferably at about the center thereof, and in thel other edge portion a corresponding bead or-tongue l0 is formed, these tongues and grooves extending throughout the length of the edge portions. The sections thus constructed are assembled edge to edge as. shown in Fig. l with the tongue l0 on each section entering the groove 9 in the adjacent section, and when thus positioned, the body-portions 5 of the several sections lie in the same plane forming an unbroken wall except for the slight depressions at thejoints between the sect-ions which extend across the sheathing in parallel lines as shown in Fig. 3.

Figs. l, 2 and 3 show the sheathing as applied to the interio-r and exterior of the side wall of a car, Fig. l being a section between two windows'and Fig. 2 being a section through-a window. The caritself may be of the usual or any suitable construction and is provided on the outer side thereof at the top and bottoniV with metallic pieces 11 and v12V of channel section running lengthwise of the car.` .The ends of the sections of the sheathing lwenter these channels and are held in plosition thereby. The truss-work 14 `'ofthe 'sideof the car has a strip 15 secured thereto andrunning lengthwise of the car and this strip'4 is of such width that. it bows t-he sections of the sheathing outwardly a small amount, that is, it causes the sections of sheathing to be bent out of line somewhat so that they are curved in the direction ofl their length on an arc of very large radius, this curvature being sufficient to flex thefsections so that they will not be subject to vibration. On the inner side of the trusswork 14, a similar sheathing 16 is provided, this bein held in position by suitable metallic strips of angular cross-section. Fig. 2 shows a window and its sash in section, 17 and 18 indicating the bottom or coping plates of the sash. The outer sheathing 13 is held at its lower end by the piece 12 and at its upper end by the plate 18. Preferably, the outer edge of plate 18 extends downwardly a considerable distance and the sections of the sheathing are of such length that their upper ends may be inserted under the edge of plate 18 and the sections then lowered to carry their lower ends into the trough of the piece 12, the upper ends of the sections being still held by the plate 18. The strip 15 puts these sections under iiexure by bowing them out slightly. The inner sheathing 16 is held in position` by the plate 17 and an angle piece 19 secured to the floor of the car. Itwill thus be seen that the side wall of the car consists of two walls of metal, one or both of these being under spring tension so as to prevent vibration, the two walls limiting very much the radiation of heat, and the complete structure being fireproof. The interlocking of the sectionsl of the sheathing holds them against relative movementand the integral edge portions of the sheathing strengthen the body portions to resist damage thereto; if any portion of the sheathing should become damaged, the sections thereof may readily be withdrawn and new ones substituted. The sect-ions being of pressed sheet metal, may be manufactured at comparatively small cost and, though comparatively thin, possess ample strength. The sections are so shaped as to provide insulating chambers vtherein which,` either when they contain only air or when packed with heat-non-.conducting material, reduce the transmission ofheat through the Wall of 'the car so that the temperature within a car having the sheathing applied thereto will be higher in winter and lower in summer than that in cars as heretofore constructed.

Having described my invent-ion, what I claim as new therein and desire to secure by Letters Patent of the United States is:

1 A metallic sheathing comprising a plurali-ty'l of assembled sectionsA of thin sheetmetal each having a body portion and the body portions of. the several sections lying in substantially the same plane to form a wall, certain of said sections each having integral edge portions at the lateralV edges inmate thereof turned at an angle and lso formed as 4to interlock a section with the sections adjacent thereto to hold it in position, and cer-v tain of said sections being removable from the sheathing independently of the parts adjacent thereto by a movement of the section away from said walll, substantially as described.
