TANK-CAR.

Specification of Letters Patent.

Patented Jan. 15, 19118.

Application filed October 29, 1917. Serial No. 198,913.

To all whom it may concern;

Be it known that I, FRANK M. STEVEN- SON, a citizen of the United States, and resident of Sharon, in the county of Mercer and State of Pennsylvania, have invented a new and useful Improvement in Tank-Cars; and I do hereby declare the following to be a full, clear, and exact description thereof.

This invention relates to supports and more particularly to tank supports for tank cars and has for one of its principal objects to provide a device of this character that will be constructed of cast metal, and one that will be more efl icient, durable and cheaper to manufacture than the forms of supports heretofore used, which have been made principally from pressed metal.

A further object of my invention is to provide such a support that may be adapted for use on different sized cars and one that will be stronger than those constructed of pressed metal and so constructed as'to eliminate danger of crackling or breaking of the casting, or shell of tank.

Generally stated, my improved support comprises side members of cast metal having top and bottom portions supported by ribs or flanges, the side members being secured together by tie rods and spaced apart by tubular spacing members mounted on the tie rods. A top plate is secured to the side members and supports suitable cushioning means upon which the tank is adapted to rest.

Although I have shown and described one particular and preferred form of my invention, it will be understood that I do not wish to be limited to such a construction, and that various changes may be made in the construction and design within the scope of the appended claims, without departing from the spirit of my invention.

In the drawings Figure 1 is a sectional view of a tank car showing my improved supports in position;

Fig. 2 is a top plan of a support constructed according to my invention with the top plate and cushioning members removed;

Fig. 3 is a side view of one of my supports; and

Fig. 4 is a rear view of the same.

Referring more particularly to the drawings, the numeral 2 designates the side members of my device as a whole. The members 2 are composed of top portion 3, bottom portion 4, web portion or inner side 5 and supporting or strengthening ribs 6, all cast as a single unit. The top 3 is flat and extends outwardly'and downwardly on an angle and terminates in an upwardly extending flange 7. The bottom or base 4: is curved or arched upwardly, as at 8, and the end portions thereof are shaped to form bearing and securing lugs 9. The web or side portion 5 is formed integral with the top 3 and bottom 4 at their one longitudinal edge. The ribs 6 are formed integral with the side or web 5, top 3 and bottom 4 and extend outward to the free edge of the top and bottom members to strengthen and support such members.

The side members 2 are secured together by cross or tie bolts 10 and are spaced apart by sleeves or tubular spaces 11 mounted on the bolts 10. V

A top plate 12 is mounted on the upper faces of the side members 2 and has its lower edge abutting the flange 7 on each of said members. The members 2 and the plate 12 have suitable apertures 13 and 14 respectivelytherein and screws or bolts 15 are adapted to be passed through the apertures 14 and'l5 to secure suitable cushion members 16 in position on the plate 12. The cushion members 16 may be of any well known construction and material, but are preferably formed of wood and spaced apart as shown.

The whole support is secured to the car frame B by means of. bolts or rivets 17 which pass through apertures 18 in the plugs 9.

The tank supports heretofore used were formed of pressed steel to obtain strength and lightness, but such supports were very expensive and not entirely satisfactory, and no support has been produced formed of cast metal that was satisfactory; they were either too heavy and bulksome, or if light enough, lacked strength.

The present support has all the required features; it is light, strong and easily assembled; and also has the advantage of being made in sections so that worn or broken parts may be taken out and new ones substituted without the loss of awhole support as has been the practice heretofore.

The tank A is adapted to rest directly on the members 16 which have their upper faces formed to fit to the contour of the tank. The tank is secured in position on the car in any well known manner, as for instance by the usual bands and anchors (not shown).

The advantages of this construction will be readily appreciated by those skilled in the art.

Having thus described my invention, what I claim is 1. A support for tank cars comprising side members having longitudinally arched bases, means for securing said side members together, means cooperating with said firstnamed means for positively spacing said side members, and a. top plate extending across and supported on said side members.

2. A support for tank cars, comprising side members composed of a side, top and base portions, said base portion being arched, strengthening ribs between said top and base portions and formed integral with said side,

top and'base portions, and means for securing said side members together and positively spacing said members apart.

3. Asupport for tank cars composed of cast metal and comprising side members having arched bases, said side members being secured together by tie rods, spacing sleeves on said bolts for spacing said side members, and a top plate extending across and supported on said side members.

i. A support for tank cars composed of cast metal and comprising side members having arched bases, said side members being secured together by tie bolts, spacing sleeves on said bolts for spacing said side members, said side members having flanges formed on their lower ends, and a top plate extending across and supported on said side members and abutting said flanges.

5. A support for tank cars composed of cast metal and comprising side members having arched bases, said side members being secured together by tie bolts, spacing sleeves on said bolts for spacing said side members, said side members having flanges formed on their lower ends, a top plate extending across and supported on said side members and abutting said flanges, and cushioning means secured on said top plate.

6. The combination with a car having a tank supported thereon, of a cast metal support for said tank comprising side members having arched bases, said side members being secured together by tie bolts, spacing sleeves on said bolts for spacing said side members, said side members having flanges formed on their lower ends, a top plate extending across and supported on said side members and abutting said flanges, and a plurality of cushioning members secured on said top plate in spaced relation with each other.

In testimony whereof, I, the said FRANK M. STEVENSON, have hereunto set my hand.

FRANK M. STEVENSON.
