To aZZ whom it may concern:
Be it known that I, THOMAS A. EDISON, a citizen of the United States, residing 'at Llewellyn Park, Orange, county of Essex, State of New Jersey, have invented certain new anduseful Im rovements in Cement-Kilns, of
Which the ollo" the case if Wrought-iron Were used. These sections are made with flan es at their ends, and. the flanges are boltetogether. The kiln is su orted on rollers en agingl said fianges. Bbviousl theweight o such a kiln is enormous, and find in practice that for this reason the edges of the flanges begin to l disintegrate, and when this action commences the entire Wearing-surface of the flange becomes cracked or broken off.
The object of my invention is to provide a construction in which this objection Will be overcome; and to this end the invention consists in makin a kiln of cast-iron sections, the flanges being protected by steel shoes which form Wearing-surfaces for engaging the supporting-rollers. These steel shoes are of greater surface than the flanges, and being made of much tougher material there can be no danger of their becoming cracked, broken,
or disintegrated. At the same time they ef- .fectivel protect the flanges from disrupting strains y-distributing the ressure over an increased area. The shoes made secein tional can, if Worn ofi", b e remove and readlly rerlaced by fresh sections when necessary.
n order that the invention may be better understood, attention is directed to the accompanying drawings, forming part of this speclfication, and in Which- Figure 1 is a cross-sectional view through one of my improved kilns, the interior lining being removed and showing the protectingshoes in position; Fig. 2, a plan view of the same, an Fig. 3 an enlarged cross-sectional view through the Harige.
In the views corresponding parts are represented by the same numerals of reference.
The shell 1 is made of cast-iron sections of .rest lentirely on one of the oints suitable ningun' formed with flanges 2'2, which abut and ,Whichv are fastened together by bolts 3 3. Secured overthe fianges 24 2"are steel wearing-shoes 4 4, heldin place by the bolts 3. These shoes aremade sectional, as shown, and preferably the 'sections' break joints, as illustrated in Fig. 2, inorder that the Weight of the kiln may not at any time In that case there would be danger o the shoes yielding elastically and imposing objectionably heavy strainsv on the cast-ironlflanges. By
the strains are quite Wi' ely distributed over the cast-iron flanges, so that any danger of -arranging the protectin #shoes as explained the latter being crackedl or broken will be en- A tirely removed. Furthermore, since the secy tional shoes are in contact with the flanges an shearing'strains are removed from the bo ts, and since the shoes are carried entirely `outside of the kiln they may be readily re.
moved and replaced without interfering in any-Ivvay with the interior lining thereof.
aving now described mv invention, what I claim as new therein, and desire to' secure by Letters Patent, is-
1. In a kiln, the combination with a pair of cylindrical sections having abutting flanges, of -a shoe covering said flanges and comprising a bearing-surface and a securing-flange at right angles thereto, substantiallyI as` set forth.
2. In a kiln, the combination with a pair of cylindrical sections having'v abutting flanges, of a shoe com osed of two sets of L-shaped sectionsplace opposite each other and secured to said flanges, substantially as set forth. .l
3. In a kiln, the combination with a air of cylindrical sections having abuttin flnges, of a shoe composed of two sets o sections each of which has a bearing-surface and asecuring-flange, the sections of one set 'being so' placed that their 'bearing-surfaces bre joints With those of the other set, substanltially asset forth.
A4. In 4a kiln, the combination With a pair of cylindrical sections having abutting flanges, of a shoe com osed of two sets of L-shaped sections place opposite each other and break- E ing joints, substantially as set forth.
