CAR-ROOFING.

Specification of Letters Patent.

Patented Dec. 10, 1918.

Application filed December 10, 1917. Serial No. 206,485.

To all whom it may concern Be it known that I, .WJLLIAM J..B0YER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certainnew and use- -ful Improvements in Car-Roofing, of which the following is a specification.

This invention relates to car construction and in its more intense aspect to roofing for use in metallic, wood or sheet metal cars now of general construction.

One of the objects of the present invention is to provide a metallic roof more particularly designed for use on freight cars which will be of simple and practical construction and possessing great strength and durability. A further ob ect is to provide a roof of. the above general character which will be'water-proof and substantially Ironconductive of heat and cold. A further object is to provide a roof of the above character adapted to prevent inside sweating, thereby affecting the contents of the car. A further object is to provide a roof of the above general character having relatively few parts which may be easily and inexpensively constructed and assembled. A further object is to provide a roof of the first above-mentioned character possessing a certain amount of flexibility thereby to permit relative movement of the parts of a car when subjected to shocks or the like without danger of causing subsequent leakage.

Other objects will be in part obvious from the annexed drawings and in part indicated in connection therewith by the following analysis of this invention.

This invention accordingly consists in the features of construction, combination of parts and in the unique relations of the members and in the relative proportioning and disposition thereof, all as more completely outlined herein.

To enable others skilled in the art so fully to comprehend the underlying features thereof that they may embody the same by the numerous modifications in structure and relation contemplated by this invention, drawings depicting a preferred form have been annexed as a part of this disclosure,

and in such drawings, like characters of reference denote corresponding parts throughout all the views, in Which-- Figure 1 is a central transverse sectional view of a freight car showing a portion of my invention applied thereto; v

Fig. 2 is an enlarged longitudinal sectional View showing a portion of the roof;

Fig. 3 1s a detail perspective view of a portion of the sheathing;

, Fig. 4 is a detail sectional view taken on the line 4-4, Fig. 1, on an enlarged scale; Fig. 5 is an enlarged sectional view of a portion of Fig. 1 shown adjacent the section line 4--4;

Fig. 6 is a detail showing the fastening means; Figs. 7, 8 and 9 are detail sectional views of modified forms of sheathing;

Fig. 10 is a detail section taken on the line 10 10, Fig. 9. I

Referring now to the drawings in detail and more particularly to Fig. 1, 20 denotes one of the longitudinal side beams of the car to which the side sheathing 21 and molding boards 22 are adapted to be secured. A central longitudinal peak beam 23 is provided and is connected to the beam 20 by means of a plurality of joists or roofing girders 24 extending preferably entirely across the car. Additional longitudinal beams, such as indicated at 25, may be applied where necessary,

A running board 26 is supported above the peak of the car by means of brackets 27 which are riveted or otherwise suitably secured'to the roofing sheathing as appears clear in Fig. 1.

All of these parts may be made either of wood or steel as desired, according to the preferred construction and form no part of this invention except in so far as they enter into certain combinations hereinafter set forth. 1

The present invention resides more particularly in the roofing and this is referably made of a plurality of longitudinally disposed sheet metal members of the general S-shaped structure shown in Fig. 2 and extending transversely of the car. Each member is formed with an upper plain'surface ment one with another as shown more clearly in Fig. 2 to form a double roof with intermediate air spaces which may be filled with insulating material if desired. iRaised perforations 29 may be used for ventilation as shown in Fig. 3. It will also be noted on reference to this figurethat the parts when assembled will have a certain amount of flexibility and will also be water roof in construction. For instance, shoul any wa- Fig. 7 the upper surface 33 corresponding ter leak between any two members it will be caught by the lower surface 28 and drain off at the side of the car. The raised perforations 29 prevent the leakage of water therethrough and into the car.

' In Figs. 7, 8 and 9 are shown cross'sections of modified forms of sheathing. In

to the surface 27 in Fig. 3 is concaved,

. thereby to convey the water away from the in place.

seam between the two members. In Fig. 8

this same corresponding surface is provided with two grooves 34 and 35 for a similar purpose. In Fig. 9 the construction is. substantially the same as shown in. Fig. 3 only means are provided such as registering openings for receiving a bolt '36 to hold the parts Other openings are provided to receive bolts 37 for attaching the sheathing to bracket 38 and thence to the car frame.

Fig. 5 shows in detail the manner of securing the sheathing to the car. A central bolt 40 is preferably provided, the upper end of which is threaded to receive a nut 41 after the bolt has passed through an opening 42 in the sheathing. A suitable cap 43 fits over the opening, which may be flanged as shown, to prevent a relative upward movement of the sheathing with respect to the beam 23.

The side edges of the sheathing are preferably held in place by means of a fastening device of substantially the form shown in Figs. 1 and 6, that is a member 41 of L-shape cross section is provided with a plurality of teeth-like projections 45 of a size and shape substantially corresponding to the distance between the web 30 and the web 32 of Fig. 3. This member is bolted or otherwise secured to the molding board 22 by means of suitable bolts or the like passing through holes 46. It will thus be seen that when the sheathing is in place the L-shaped member 44: is so positioned as to permit the projections 45 to engage the spaces provided the parts to be readily menace in each "sheathing member and when secured in place positively prevents an upward relative movement thereof.

It is believed that the above description fully sets forth the structure and the manner of installing a metallic roofing of the general character herein set forth.

The invention is of simple and practical construction yet exceedingly durable, and one which can not be easily broken by torsional or other strains owing to its construction involving the interlocking features. The double roof formed b makes the car water-proo so far as roof leakage is concerned, and is adapted to prevent internal condensation which might damage the contents of the car. It is thus seen that the present invention is adapted to accomplish, among others, all of the objects and advantages herein set forth.

I realize that considerable variation is possible in the. details of construction and arrangement of parts without departing from the spirit of my invention, and I ther fore do not intend to limit myself to the specific form shown and described, except as defined by the appended claims.

Having thus described my invention what I claim as new and desire to secure by Letters Patent is 1. A metallic roofing composed of a series of hollow ventilating and draining channels open at the roof edge, each of said channels comprising a plurality of sheet metal members, each of said members having upper and lower surfaces in ofiset relation and connected by a web of irregular crosssection, and each surface being provided with a web of similar shape extending in opposite directions and adapted for interlocking engagement with the next adjacent member, and ventilating openings in said lower surfaces.

2. The combination with a car having a central longitudinal beam and side beams, of a metallic roofing composed of a series of hollow channels open at the roof edge, each of said channels comprising a plurality of sheet metal members, each of said members having upper and lower surfaces in offset relation and connected by a web of irregular cross-section, and each surface being prothis sheathing vidcd with a web of similar shape extending bers transversely disposed with respect to the car and forming hollow channels open at the roof edges, means for securing said members together, means for securing said 5 members to the central peak beam and fastening means co-acting directly with the lower of said sheet metal members forming said hollow channels and the side beams of the car, said last mentioned means compris- 1 ing a longitudinally disposed member of L- shaped cross section having a plurality of projections each. adapted to enter a channel and having its body portion secured to the side beam of the car.

In testimony whereof I afiix my signature 15 in presence of two witnesses.
