12 Claims;

This invention relates to car roofs, and more particularly to the running board or runway cnstructions thereof. The principal object of the present invention is to devise a strong and durable, simple, economical and efficient runway construction. Ihe invention consists in the runway construction and in the combinations and arrangements of parts hereinafter described and claimed.

In the accompanying drawings, which form part of this specification and wherein like symbols refer to like parts wherever they occur,

Fig. 1 is a plan view of a portion of a car roof provided with a running board or runway conr struction embodying my invention,

Fig. 2 is a vertical transverse section through one-half of the roof on the line 2-2 in Fig. l,

Fig. 3 is an enlarged vertical transverse section through the ridge portion of the roof on the line 3 3 in Fig. 1,

Fig. 4 is a vertical longitudinal section at the ridge on the line 4--4 in Fig. 3,

Fig. 5 is a fragmentary plan view of a roof pro- .vided with a modified form of running board or runway construction,

Fig. 6 is a Vertical transverse section on the line Ii--B in Fig 5,

Fig '7 is a vertical longitudinal section through the roof at the ridge line on the line I--1 in Fig. `5; and

Figs. 8 and 9 are similar sections takeny on the lines 8-8 and .Q -9, respectively, in Fig. 5.

In the construction illustrated in Figs. 1 to 4, `the roof comprises metal roof sheets I that slope downwardly from ridge to eaves of the car where they are turned down and riveted or otherwise rigidly secured to the side plates 2. The roof sheets I are connected by upstanding seams that extend transversely of the roof from eaves to eaves thereof and comprise upstanding flanges 3 along the adjacent side margins of said sheets and inverted U-shaped seam caps 4 that straddle said flanges and are riveted or otherwise rigidly secured thereto.

The roof is provided at the ridge with a longitudinal running board or runway construction comprising side sections 5 of wood or other nonmetallic anti-slipping material and an intermediate or middle section 6 of metal whose upper surface is roughened or coated with a suitable material 'I, such as sanded bituminous paint, to prevent slipping of the brakemen. The intermediate section 6 is preferably of inverted channel-shaped section and has outstanding base (Cl: 10S-5.4)

flanges 8 at the lower edges of its side walls that constitute supports for the wooden side sections 5, These `wooden side sections are preferably set in suitable cement 9 applied to the upper surfaces of Ysaid base flanges of the metal intermediate section. l

At each roof seam, thebase flanges 8 ofthe metal runway section 6 rest on and are preferablyl secured by rivets I0 or other fastening means to the lateral top flanges of angle-shaped brackets I I that are disposed on opposite sides of thevridge and have their vertical flanges secured flatwise to one side of said seam by the securing rivets therefor. The wooden running board sections 5* arev also secured to the base flanges 8 of the metal intermediate section 6 and to the top anges of the supporting brackets II by means of bolts I2 whose heads are seated in countersinks provided therefor in the tops of said wooden sections.

In the modified construction illustrated in Figs. 5 to 9', the roof comprises plain roof sheets Ia whose adjacent marginal portions are supported on the flat top portions of inside carlines 4a of inverted channelshaped section. In this construction, the roof sheets are offset upwardly at the' ridge to form the metal intermediate section 6a Iof the longitudinal runway of the roof; and strips of wood orv other nonmetallic material are arranged on opposite sidesof said raised ridgeportion to form the side sections 5w of said runway. The side sections 5a are held down on the roof by means of bolts' I3- that have their lower ends riveted to the tops of the inside carlines 4a and are provided at their upper ends with nuts' that are seated in recesses provided therefor in the tops of said side sections. The raised ridge portions of the sheets` that form the intermediate metal runway section 6a are provided with a suitable anti-slipping surfacing 1a. Except at the raised ridge portions 6a of the sheets, the adjacent side marginal portions of said sheets are overlapped and secured together and to the tops of the inside carlines by rivets I4. At such raised ridge portions the adjacent side marginal portions of the sheets are notched, as at I5, to provide spaces that are filled with ush welds I6 that unite said marginal portions to the underlying carlines and avoid formation ofribs or obstructions on the top surface of the runway.

The hereinbefore described runway construction is simple and economical and can be quickly and easily attached to the roof. It dispenses with the use of the wooden intermediate runway section heretofore employed and thus reduces the cost and weight of the runway. The

metal intermediate runway section serves to support the wooden side section and stiifen and strengthen the entire runway.

What I claim is:

1. A car roof having a runway comprising nonmetallic side sections and a metal intermediate section having a flat upper surface substantially flush with the upper surfaces ofV said nonmetallic side sections.

2. A car roof having a runway comprising wooden side sections and a flat topped metal intermediate section, and an anti-slipping surface on said flat topped metal intermediate section substantially flush with the upper surfaces of said Wooden side sections.

3. A runway assembly adapted for application as a complete unit, said runway assembly cornprising nonmetallic side sections and a metal intermediate section, said metal intermediate section having portions that constitute supports for said nonmetallic side sections, and means for securing said nonmetallic side sections to said supports.

4. A car roof having a runway comprising an intermediate section of substantially inverted channel-shaped section with outstanding base flanges and side sections supported on and secured to said base flanges.

5. A car roof having a runway comprising nonmetallic side sections and a metal intermediate section of substantially inverted channelshaped section having outstanding base flanges that constitute supportes for said nonmetallic side sections, and means for securing said side sections to said anges.

6. A car roof having a runway comprising wooden side sections and a metal intermediate section, said metal intermediate section having outstanding side flan-ges that constitute supports for sai-d wooden side sections, means for removably securing said side sections to said anges, and separate means for securing said flanges to said roof.

7. A car roof having a runway comprising Wooden side sections and a metal intermediate section, said metal intermediate section having downwardly offset outstanding side marginal flanges that constitute supports for said wooden side sections, means for removably securing said wooden -side sections to said flanges, and brackets for securing said flanges to said roof.

8. A metal car roof having a runway comprising iiat topped side and intermediate sections having substantially flush upper surfaces, said side sections being made of nonmetallic material, and said roof being offset upwardly between said nonrnetallic side sections to form said at topped metallic intermediate section.

9. A metal car roof having a runway comprising nonmetallic side sections and a metal intermediate section having a flat upper surface substantially ush with the upper surfaces of said nonmetallic side sections, said roof being oiset upwardly to form said intermediate metal section, and said nonmetallic side sections being secured directly to said roof on opposite sides of said upwardly offset portion thereof.

10. A metal car roof havin-g a runway extending longitudinally of the car at the ridge, said runway comprising nonmetallic side sections and a metal intermediate section having a flat upper surface substantially iiush with the upper surfaces of said nonmetallic side sections, said roof being offset upwardly at the ridge to form said metal intermediate section, and said ncnmetallic sections being secured directly to said roof on opposite sides of the upwardly offset ridge portion thereof.

11. A metal car roof having a runway extending longitudinally of the car at the ridge, said runway comprising wooden side sections and a metal intermediate section, said roof being offset upwardly at the ridge to form said metai intermediate section, and said wooden side sections being secured to said roof on opposite sides of the upwardly offset ridge portion thereof, and carlines located beneath said roof and having their ridge portions oiTset upwardly to support said upwardly offset ridge.

12. A car roof comprising side plates, carlines extending from side plate to side plate, roof sheets extending from side plate to side plate with their side margins supported on said carlines, and a runway extending longitudinally of the car at the ridge and comprising a metal intermediate section and nonmetallic side sections, said roof sheets being offset upwardly at the ridge to form said metal intermediate runway section, and said nonmetallic side runway sections being secured to said roof sheets on opposite sides of the upwardly offset ridge portions thereof, said carlines being offset upwardly at the ridge to support said upwardly offset ridge portions of said sheets, the adjacent margins of said sheets being spaced apart and welded together and to said carlines along their upwardly oiset ridge portions and being overlapped and secured together and to said carlines on opposite sides of their raised ridge portions.
