BUILT-UP LADLE.

Specification of Letters Patent.

Patented Oct. 24, 1911.

Application filed May 6, 1910. Serial No. 559,705.

.To oZZ whom it may concern:

Be it known that I, MUNsoN H. TREAD- WELL, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Built- Up Ladles, of which the following is a full, clear, and exact specification.

This invention relates to built up ladles, and more particularly has reference to what are commonly termed cinder ladles,7 that is ladles used for carrying away slag, etc. from blast furnaces, or foundries. Such ladles are commonly made of cast iron, and are not ordinarily lined with refractory material, and consequently are subject to burning out and other accidents. Where a ladle is cast in one piece, and especially a ladle of large capacity, when a burn out occurs the ladle is useless and must eventually be scrapped, as the value of the metal is considerable. In order to utilize the metal such a casting must be broken up, which has been found difficult and expensive in the case of large and heavy cast ladles.

The object of this invention is to provide a ladle which can be constructed of rolled plates, preferably steel, and unlined, which can be riveted together and cut up when necessary to be scrapped, with inconsiderable expense. The invention, furthermore enables small holes to be patched, or to have parts renewed, without destroying the usefulness of the entire ladle.

A further object of the invention is to provide improved supporting means for a built up ladle.

The invention will be more fully understood in connection with the accompanying drawing, wherein Figure l is an elevation partly in section of a ladle embodying the invention, and Fig. 2 is a top plan view.

In building up a ladle of plates, it is essential that the interior be smooth and free from projections or interstices in which the skull can bind and thereby prevent discharge of the entire contents. In order to accomplish this, the ladle embodying my invention is constructed of a number of rolled segmental plates 1 having their edges closely abutting and fastened together by external lapping plates 2, riveted together by rivets 3, having their heads interiorly countersunk as at 4 in Fig.- 2. Thereby, is formed an annular conical shaped body open at top and bottom, which is strengthened by intermediate hoops 5 riveted to the segmental plates between the lapping plates 2, and to which are attached hoop members 6 overlying the lapping plates 2 and connected to the hoops 5. 7 are bumping plates, preferably carried by the lapping plates 2 above the hoop members 6 to take the shock when the ladle is mounted on a dumping car according to the known practice. At the top, above the ends of the lapping plates 2, is externally fastened a top hoop or rim 9, preferably consisting of an angle bar bent and rolled to proper shape, forming a strong and at the same time light rim. At the bottom is fastened a second angle plate 11 having its flange turned outwardly and slightly downwardly. l2 represents a bottom which may be a casting, forging or plate having a flange 13 through which and the flange 11 and fastening bolts 14 are passed, securing the bottom to the body. The interior edge of the bottom is made to fit the bottom of the body 1, so that no spaces or interstices are formed in which the skull can take hold. In order to mount the ladle on a cinder car, it is provided with feet 16, which may be castings adapted to rest on a bail or yoke 17, and riveted to the body plates 1, preferably. The feet 16 are recessed to tit the hoops 5 above and below, and riveted to the body plates 1 as shown, and thereby a firm support secured, it being seen that should the plates 1 become red hot the hoops 5 would still carry the strain from the feet and thereby the whole weight is not directly supported by the body plates 1.

From the foregoing description, it is thought the advantages of the invention will be understood, and it will be seen that by the invention is provided a built up plate cinder ladle which can be cheaply and economically built in large sizes and readily cut apart when worn out.

Various changes in the details andV specific construction herein shown may be made without departing from the scope of the invention.

Having thus described my invention, I declare that what I claim as new and desire to secure by Letters Patent, is`

1. A built up cinder ladle comprising segmental plate sections having their edges abutting to form a conical body having a smooth interior, outside lapping plates secured to said abutting sections, an external hoop carried by said body adjacent the lower end, and a bottom separably attached to said hoop.

2. A built up cinder ladle comprising segmental plate sections having theirV edges abutting to form a conical body having a smooth interior, outside lapping plates secured to said abutting sections, a flanged strip hoop secured to said plates around the top and bottom edges of said body, and a bottom section separably secured to the flange of said bottom hoop.

3. A built up cinder'ladle comprising a conical body formed of segmental plate sections secured together by longitudinal outside lapping plates, a flanged hoop secured around the bottom portion, and a bottom section separably carried by said hoop.

4. A built up cinder ladle comprising a conical body formed of segmental plate sections secured together by longitudinal outside lapping plates, an intermediate plate hoop secured to said sections, a bottom section, and supporting feet secured to certain of said sections and braced by said hoop.

5. A built up cinder ladle comprising a conical body formed of segmental plate sections secured together by longitudinal outside lapping plates, an intermediate plate hoop secured to said sections, supporting feet adjacent said hoop, a flanged bottom hoop, and a bottom section carried by said flanged hoop.

In testimony whereof I aiiiX my signature, in presence of two witnesses.
