ADDISON S. HODGES, OF HYDE PARK, ASSIGNOR OF ONE-HALF HIS RIGHT TO EDWARD B. WILDES, OF IPSWICH, MASSACHUSETTS.

IMPROVEMENT IN STOVE AND FURNACE LININGS.

Specification forming part of Letters Patent N 0. 198,940, dated January 8, 1878; application filed November 12,1877.

To all whom it may concern:

Be it known that I, ADmsoN S. Honens, of Hyde Park, in the county of Norfolk and State of Massachusetts, have invented certain new and useful Improvements in Stove and Furnace Linings; and I do hereby declare that the following is a full,'clear, and exact description thereof, which will enable others and wrought metallic lining, made as follows:

The interior or central portion of my improved lining is made of wrought-iron waste or sheetiron clippings, or other suitable wrought, or rolled, or hammered wrought-iron scrapsuch as, for instance, galvanized-iron or tinnediron strips, &c.which waste wrought-iron is flattened together'to a shape analogous to that of the stove-lining piece that is to be cast, but somewhat smaller, so as to serve as a porous and elastic core. This core is inserted in a mold of the size of the desired lining, and melted wrought-iron scraps or waste is cast around the aforesaid flexible wrought-iron core, as well as between its diderent together, preventing the lining and cracking. a

Melted wrought-iron produces, when cast, a very hard and fire-proof surface, very well furnaces, &c., but, owing to its extreme hardness, is sometimes liable to crack when exposed to extreme and varying temperatures. This difficulty I have from warping successfully overcome, by uniting with the exterior melted 'wroughtir'on shell an interior elastic and porous wrought-iron scrap or waste core, by which all liability to cracking is entirely obviated. This lining is very durable,

' and, owing to its hard and smooth surface, prevents the accumulation of clinkers thereon,

which is a great fire-brick linings.

Ordinary cast-iron may be used, and melted and poured around the aforesaid central elastic and porous metallic Wrought-iron-scra'p difi iculty with the ordinary parts, by which the whole is, as it were, knitted and held very firmly,

core; but I prefer to make the shell or exterior portion of melted wroughtiron,sheet or scrap iron, as a harder and more durable surface is thus obtained as compared with ordinary cast pig-iron. I

The central elastic and porous wroughtiron-scrap core may, in. some places, project to the exterior of the cast shell without departing from the spirit of my invention; but

I prefer to cast the shell all round and con1- somewhat smaller in every direction. Around this core, and between its parts, is cast the metallic exterior cover I) b b, as shown. The lining may, of course, be provided with flanges or ribs, in the usual manner, so as to fit any desired stove, furnace, or fire-place, as may be required.

I am aware of the patent granted to E. M, Hendrickson, March 19, 1867, No. 63,046,i11

which spiral wires are laid in a mold and iron cast around them; and I am also aware of .the patent granted to G. H. Onions, 1875, No. 168,408, in which lapped rings are used in a similar manner; and I here wish to state that I do not claim anything as set forth in either of said patents as my invention.

Having thus fully'described the nature and construction of my invention, I wish to secure by Letters Patent, and claim The herein-described improved stove or furnace lining, consisting of the interior elastic.

and porous wrought-iron-scrap core a a a, and the metallic shell I) b I) cast around it, in 'a manner and 'for the purpose as herein set forth.

In testimony that I claim the foregoing as,

my owninvention I- have affixed my signature in presence of two witnesses.
