To. all whomit may concern;

Be it known t at I, CARL P'. As'moma citizen of the United States, residing atHasbrouck Heights, in the county of Bergen and State of New Jersey, have. invented certain new and useful Improvements in Built.-

- Up Ladies, of which the following a. full, clear, and exact specification,

This invention relates. tobuilt. up ladies,

and more particularly has. refierence towhat.

are commonly termed cinder ladles that. is ladles used for carrying awaysliag, etc., from blast furnaces, or foundries. Such ladles are commonly made 0t cast iron, and.

' such a casting: must be broken up, which has been found diflicult and expensive in the case of large and heavy cast lad es- The object of this invention relates to the construct onof a built up ladle composed tiguous plates will all be subject. to equal temperatures, and thereby racking and shearing of the fastenings avoided.

A further object of the invention is to provide a built up ladle having the jointsof contiguousplates always sub ect to equal temperature, and means whereby the interior of the ladle will be smooth and free from interstices tending to cause the skull to bind and fill up when the ladle is dumped.

A further object of the invention is to provide improved supporting means for a uilt up 1 The invention will be more fully underit stood in connection with the accompanying drawing, wherein- Figure 1 shows an elevation of a ladle embodying the invention;' Fig. 2 is a top plan view; Fig. 3 is a detail view showing the manner of securing the bottom, and Fig. 4 .is a detail view showing the preferred manner of securing the plates, and of form-' ing a smooth interior.

' Accordin to. this invention, I form a ladle body y outwardly flanging a number of segmental plates 1, so as to have vertical external. flanges 2 which will be securedtogether by rivets or other fastenings 3. In

. order to, avoid corners and interstices where the plates 1 bend outwardly, I provide filling blocks 5.. which are sha ed to. fit the outwardly curved portions 0 the lates 1 and may be held by. the fastenings Thereby,

a ladle having -a practically smooth interior .will be provided in which the skull will not catch and bind. It. will be seen that when a ladle. thus; constructed is heated by pouring,- molten .or hot material therein,

such as. cinder, adjoining portions of the plates, 1 and the. flanges 2 will be heated to- .the same temperature, and consequently there. will not be any transverse shearing 'i strains: on the faste gwhere contiguous portlons of the plates, or of the fastenings, are. subjected to. di-fierent itemperatures. The. fil1ing sub ect to the same conditions and Wlll ex- .pand and contract with the plates without.

s 3 as might happen blocks: 5 are also.

straining the fastenings, which latter will f be subject throughout to practically the same temperature. simllar arrangement is provided for securing the bottom, as in Fig. 3.. of plates wherein the jolnts between. cen- 7 represents a flanged 0r dished plate having a flange 8 which is secured tothe lower ends, of the annular body plates 1 by fastenings' 9, an annular filling rim 10 being here used to fill up the space and avoid corners which would cause the skull to bind. It 'will be seen that the fastenings 9 and the bottom flange 8 will be subject to practically even temperature, and thereby shearing strains avoided. Furthermore, by this method of externallyl fastening the side plates together, and t e bottom plate to the side plates, no part of the fastening is inside the ladle and subjected to direct heat of the contents, which, so far as I am aware, is broadly new and renders a built up ladle more durable and'less liable to deterioration of the fastenings through the constant expansion and contraction they necessarily have to withstand. By this method shearing strains are practically entirely done away with, since t e parts contiguous to the fastenings are always of practically the same temperature, one-part of the fastening not being at a higher temperature than another part.

11 represents a top hoop or rim comprising an annular angle bar externally riveted to the tops of the plates and cut out to overlie the flanges 2 and filling blocks 5, as shown in Fig. 2. Thereby, the flanges support and strengthen the rim 11, and the latter prevents injury to the edges of the plates 1. Intermediate hoops 14, 14, 14' are shrunk or otherwise fastened on the outside of the body, the lower hoop being held by lugs 16 in the flanges'2 and the upper hoops by lug plates or cast lugs 17 18 riveted to the flanges 2. These pairs of lugs 17 and 18 also act as feet to support the bail or yoke 19 on which the ladle is commonly mounted .in a' car frame.

pacity. When the ladle is worn out, it can be readily cut up to enable the 'metal to be recovered, without much expense.

Modifications and changes may be made in the details and construction herein shown 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 ladle comprising segmental plates having outwardly turned edges, securing means passing through said edges, and interior filling blocks between said plates.

2. A ladle comprising segmental plates having outwardly turned ed es, external securing means passing throng said edges, andfilllng means held between said plates by said fastening means for forming an interior surface free of interstices.

3. A ladle comprising an annular body portion and a bottom plate secured thereto, said bottom plate being rovided with an outwardly turned. flange, asteninis-passing through said flange and annular dy, and a filling ring between the bottom plate and the body.

4. A ladle comprising an annular body formed of outwardly flanged segmental plates, filling blocks interposed between said plates, fastenings securing said flanges and blocks together, an inverted flanged bottom member, a filling ring interposed between said bottom and the body, and fastenings r'or securing saidbottom member and filling ring to said body.

5.-,A ladle comprising an annular body formed of outwardly flanged segmental plates, external fastenings passing through said flanges, a top hoop passing exteriorly around said bodyand overlying said flanges,

and a bottom member secured to one end of said body.

6. A ladle comprising an annular body formed of outwardly flanged segmental plates, external fastenings passing through said flanges, external hoops around said .flanges, and a bottom member secured to one end of said body.

In testimony whereof I afiix my signature,

in presence of two witnesses.
