Description
y ,i iuitl gisten www rrUe'fH MCDONALD, or rurtrssune, PENNSYLVANIA, AssIeNoR-Tol yHMSELF AND WILLIAM STUART, OF lSAME PLACE.
Leners Paten: Nasesvs, dated March 9,1869.
To all whom it may concern: A
Be it known that I, HUGH' MCDONALD, of thecity of Pittsburg, in the county of Allegheny, and State of Pennsylvania, have invented a new and useful Improve- 1 ment in l uddling-Furnaces and I do hereby declare the following to be a full, clear, and exact description thereot', reference being had to the accompanying drawing, making a part of this specilieation,iu Which-` Figure l is a perspective view of a a. paddling-furnace, partly in section, illustrative ol' my improvement;
Figure 2 is a horizontal -section of a portion of the bottom plate;
lFigure 3 is a horizontal section of the fore plate; and
Figures 5 and Gare perspective views of the wroughtiron bars, frooved, notched, corrugated, or perforated, on or around which I cast the bottom plate, fore plate, and door-frame of the puddling-furnace.
Like letters of' reference indicate like parts in each.
The nature ot' my invention consist in casting the pnrts'of a puddling or boiling-,furnace most subject to' the intense heat, on ora-round oneor more wroughtiron bars,-plaoed in the moulds in which such parts are to be cast, such wrought-iron bars being'first notched,
- erooved, serrated, corrugated, or perforated, so that the fluid cast-metal shall run into and fill up such notches, grooves, or perforations. Then, when, under the effect of the. intense heat required in paddling and boiling-furnaces, the bottom plate, or other part so made, breaks or cracks, .the wrought-iron bar or bars will hold the broken pieces in close contiguity, so that they may con- `tinue to be use d.
are thus seriously irri ured, if not rendered useless. To
lovrercor'ne this diliculty, I cast each of the parts named on orarouud one or more wrought-iron bars e e e.
These bars are notched, or serrated in their edges, as shown at i, or have grooves running across the iudentations in their faces, or are corrugated, or are perforated at intervals, as at or the notches, perforations, &c., may be combined in-the same bar.
These bars, in any desirable number, and of a. suitable length, are set in the moulds in -Which the plates a or b, or frame c, as the case may be, areto be cast, and are so placed that the metal, when poured. into the moulds, shall run in on all sides of the bars, and also so that the bar, or bars, in the nished casting, shall extend lengthways ofthe `part in which it or they are cast, as shown in fig. 1, or, in other words, at right angles to the most frequent line of breakage. Then, when either the bottom plate a, or fore plafeb, or frame c breaks or cracks, the pieces will be held tov gether by the cast-metal in the notches,- grooves, corrugations, or perforations of the wrought-iron bar or bars.
` Thus the pieces will he prevented from slipping apart even when the cast-metal of the part is broken entirely in two; and the wrought-iron bar or bars, not being' affected by heat in the same Way, will not crack or break. The durability of the furnaceis thus greatly increased, with little or no increased cost.
Steel bars may take the place of the iron bars for the purposes`deseribed.
What I claim as my invention, and desire to secure by Letters Patent, isi The mode hereinbefore described, of making the several parts of a, puddliug or boiling-furnace, by casting such part or parts on or around one or more notched,
grooved, serrated, or corrugated bars, iron or steel, substantially as described.
4In testimony whereof', I, the said HUGH MODONALD, have hereunto set my hand.
` HUGH MODONALD. Witnesses:
A. S. NICHOLSON, G. H. CHRISTY.
