AIR AND MOISTURE PROOF CONTAINER FOR CONTAINER CARS 5 Sheets-Sheet 5 Filed Dec. 9, 1930 Patented June 28, 1932 UNITED STATES PATENT OFFICE GRAHAM C. WOODRUFF, OF IBRONXVILLE, NEW YORK, ASSIGNOR TO THE PORATION, A CORPORATION OF DELAWARE L. O. L. COR- AND MOISTURE PROOF CONTAINER FOR CONTAINER CARS Application filed December 9, 1930. -Serial No. 501,146.

I This invention relates to goods containers for what are known as container cars, wherein individual containers for holding goods to be shipped are adapted to be disposed and held upon the container car body for separate removal and transportation to a consignee at a destination point.

Containers of this character have'heretofore been designed and used for shipping various materials and commoditiesin bulk, including some, such as a cement and J1me,

- that are deleteriously affected by exposure to air and rainwater or other moisture. Such containers as have heretofore been used, however, for the shipping for example of lime and cement are required to be only reasonably or to a fair degree proof against access of air or moisture, whereas a container for shipping calcium carbide or other substances which quickly gasify or liquefy on exposure to air or water must be of a hermetically sealing type and absolutely proof against entrance of air or moisture in order to be successfully used. Moreover, a container for 'bulk shipment of carbide must be constructed so as to be not only capable of being handled with a minimum degree of liability of inury thereto but of sustaining rough handling 'without danger of starting seams or othera: wise causing-damage allowing leakage of air or water into the container. In addition .a

container capable of successful use for ship-- ping carbide must be of such construction as to readily shed water, to have any filling and discharge openings therein .sealed securely against entrance of air'or water, to be seamless or without seams liable to leak even under severe shocks and jars, to be proof .1 in air and water-tight cans,

approximately 300 lbs., which cans are loaded in ordinary box cars. A carload 'consists of against bursting .from pressure unavoidably generated therein, and to be manufactured and operated at ajsaving over the cost of shipping the material in the usual way. I

Under usual practice carbide is shipped each weighing approximately three hundred of'these cans containing from 40 to tons of carbide. Such cans are of the non-returnable type,

of the cans and the of any gas it being necessary to cut them open just prior to discharging the contents to the generator, and the cost of these containers and the inability to use them more than once makes the cost of packing and transportation comparatively high. This usual practice of shipping carbide in 300 lb. cans is sometimes departed from by the use of specially returnable containers holding a somewhat larger quantity and which, after being unloaded at the destination point, must be shipped for refilling back to the shipping point at freight charges.

The object of the present invention is to provide a container for shipping carbide in bulk,'which may be repeatedly used and which will have the qualifications set forth required for successful use in the shipment of carbide and like materials. This con tainer in practice may be made of any suitable size and containing capacity, but preferably is made of a capacity for holding 10,000 lbs. of-carbide and of a size adapted for interchangeable use on a container car with brick and lime containers, thus enabling its use without change of structure of present container cars. This improved container embodies .the advantage over ordinary carbide containing cans and special receptacles of the character referred to in holding and transporting many times the quantity of carbidein bulk at a ti1n e,,andv of being repeatedly used for this purpose, thereby saving the cost freight charges to the shipper for returning special containers freighted back in empty condition to the shipper; also by facilitating and reducing handling charges atthe shipping and destination points.

A carbide container constructed in accordance with the invention is shown in the accompanyingdrawings, in which:

Referring now more particularly to the drawings, 1 represents the improved container, which, generally speaking, comprises a body portion 2, a hopper bottom 3 having a discharge outlet 4, and a neck portion 5 provided with a filling mouth or inlet 6.

The body and hopper portions of the container are preferably of rectangular or oblong rectangular form, a container of oblong rectangular form being shown in the present instance, and such container is formed of a suitably pressed steel metal frame and steel sheet metal plates secured thereto. The framing consists, as shown, of a bottom horizontal framing 7, a top horizontal framing 8, each in the form of an oblong rectangular loop,

- and angle metal corner posts 9 extending between said top and bottom framings. The bottom framing 7 forms a base on which the container is designed to rest and consistsvof angle metal side and end bars or sills mitred at the ends and suitably connected by steel gussets 10 secured to the horizontal flanges of the sills, while the upper framing 8 consists of pressed steel bent side and end bars secured to each other and to knee'braces 8' and uniting the upper ends of the L-shaped angle metal corner posts. In addition, an intermediate framing 11 formed of angle metal bars may be arranged along the sides and rear end of the container at the juncture of the body 2 with the hopper bottom 3, which bars will operate in conjunction with horizontal Z-

bars

12 and 13 at the top and bottom of the outlet 3 and with the corner posts 9 with which they are connected to form a stifl'ening framing rigidly tying and uniting the posts and plates of the container body and ottom and the parts of the top framing 5 of the neck portion 5, to give great strength and rigidity to'the container structure.

The formation of the body portion 2 and hopper bottom 3 is completed by steel sheet metal plates 14 of suitable thickness which are secured to the framing members 7 8 and 11, to the corner posts 9 and to the Z-

bars

12 and 13 to provide the front side and end'walls of a main holding compartment and the side and front end wall of a bottom compartment, which bottom compartment is partitioned off and completed by other sheet metal plates to form a hopper bottom. Plates 15 similar to the plates 14 extend from the body 2 and top frame 8 upwardly to form the side and end walls of the neck portion 5, which is of tapering or frusto-pyramidal form and terminates at its restricted top in the mouth or filling inlet 6, which is made of a pressed steel collar 15 having a vertical upper flange portion 17 and an outwardly and downwardly inclined bottom flange portion 18, to which latter the upper edges of the sheets 15 are secured. The sheets lapped with respect to each other and to the framing members and collar and are welded together or riveted in such manner as to make the seams absolutely air and watertight. The downwardly and outwardly sloping sheets 15 of-the neck portion of the container not only provide a roof structure for the container which will shed icifsnow and water, but also provide an upper compartment leading from the main storage chamber in the body to receive therewith and with the hopper bottom the load of carbide, and which, on account of its progressively reduced cross-section from bottom to top, adapts the container to be filled solidly to the top so as to reduce the unoccupied space in the charge container to a minimum, thereby practically eliminating any space in the filled container for air or moisture which may have a deleterious action on the charge. The sheets forming the walls of the body and hopper bottom may be continuous between the

framings

7 and 8 and secured thereto and to the framing 11 or separate sheets for the body and hopper portions may be used which will be properly lapped and welded or riveted at the joints. The sheets 15 are lap ed at their corner angles by angle metal ri ge bars 19 forming the top frame 5, extending from the collar 16 downwardly to the framing 8 and provided at their lower ends with caps 20 overlapping the sheets at their angles of intersection with the corner posts 9 and sheets 14, which ridge bars and caps are riveted or welded to the other parts referred to and seal all joints between the sheets 15 and stifl'en and strengthen the'same to obtain a neck portion of great strength and rigidity.

The container is provided with the lateral outlet 4 near its bottom and the inlet 6 at its top, in order to adapt it to be conveniently filled while in an upright position and to obviate the necessity of inverting it to discharge its contents through the top opening, which would require the rovision of several manipulating means ans increase the liability of damage to the container. I p the preferred construction employed'fbut, within the scope of the invention, the bottom outlet may be omitted and the opening 6 used both as inlet and outlet, where'the user, for sake of cheapness of construction, is willing to assume the inconveniences and risks of the disadvantages mentioned.

Riveted or welded to the outer side of the flange 17 of the collar 16 is a holding ring 21,

to which are pivoted swing bolts or equivalent fastening members 22. These bolts are 14 and 15 are properly Ill adapted for engagement with notches in keeper projections 23 on a cover-or closure plate 24 designed to seal the inlet 6. This cover plate is provided with a body portion having marginal flanges 25 on which the keepers 23 are formed, the body being depressed below the plane of said flanges, which lie in an elevated plane parallel therewith. This construction of the cover body and its marginal flanges provides around the body and beneath the flanges a marginal recess receiving an angular metallic packing ring 26 which is arranged to seat upon and to be engaged by an inwardly extending flange from the holding ring 21, whereby, when the swing bolts 22 are engaged with the keepers 23 and the nuts thereof tightened, an absolutely reliable air and water-tight closure of the opening 6 will be effected.

The outlet 4 is provided with a seat frame 27 formed by angle metal top, bottom and side pieces, secured to the Z-

bars

12 and 13 and to marginal portions of the plates 14 at the sides of the outlet. The frame bars 27 carry swing bolts 28 similar to the swing bolts 22, which are adapted for engagement with notched keepers 29 on the marginal flanges 30 of a closure plate 31, the body and flange of this plate being similar in construction to the body and flange of the cover plate 24 and forming a seat recess for an angle metal packing ring 32, whereby when the swing bolts 28 are engaged with the keepers 29 an absolutely reliable air and waterproof closure of the outlet 4 will be effected. It will be observed that the parts forming the outlet and its closure are set back of the plane of the plates'l4 of the frontwall sothat said outlet and its closure lie wholly within the plane of the container, obviating liability of damage thereto in the handling of the container.

The container is provided at each of the reinforced upper corners of its body with a li ting eye or link 23, to permit handling of the container by overhead lifting devices in a well known way, and pressed steel guiding and retaining shoes or

members

34 and 35 at the opposite sides adjacent the ends thereof for coaction with guiding and retaining

members

36 and 37 on a gondola or other suitable container car 38 to position the container properly on the car with respect to other containers and to secure the same against displacement.

In practice, the loading, handling and unloading operations may be carried out as fol lows:

The container, with the closure 31 applied and closure 24 removed, is placed under a chute and the carbide allowed to flow from the chute through the filling opening 6 into the container until the latter is completely filled. The closure '24 is then applied and the filling opening sealed, thus making the container air and moisture proof, whereupon the container is swung into position on the container car if not already on the car, and

transported by the latter to its destination.

point. The container is then lifted from the car by engagement of suitable lifting means with its eyes or links 33 and swung into position above the bin or receptacle into which the load of carbide is to be discharged, the closure 31 then opened and the load permitted to flow by gravity out of the container into the receptacle. By this manner of discharging the load it will be seen that the load may be discharged while the container is in an uprightor substantially upright position, thus obviating the necessity of turning it over or inverting it to discharge the load, Which operation would require additional lifting devices and involve a greater risk of damage to the container while being manipulate In order to facilitate the discharge of the load, and to ensure the discharge of all the load while the container. remains in asubstantially upright position, the hopper or discharge portion 3 of the container may have its side walls 39 and bottom wall 40 sloping relatively to each other and toward the outlet 4, so that a gravity discharge with the container in upright position may be effected.

From the foregoing description, taken in connection with the accompanying drawings, the'construction, mode of use and advantages of my improved container for container cars will be readily understood without a further and extended description, and

it will be seen that a container is provided which is effectually adapted for safely handling and transporting carbide and other like substances. While the construction of the container as disclosed is preferred, it will, of course, be understood that changes in its form, construction and arrangement of parts, within the scope of the appended claims, may be made without departing from the spirit or sacrificing any of the advantages of the inventio Having thus fully described my invention, I claim 1.
