FIRE-POT LINING.
SPECIFICATION :forming part Of Letters latent NO. 658,546, datedrseptember 25, 1900. Application iiled February 13, 1899. Serial No. 705,437. (No model.)
T O a/ZZ whom, it' may concern:
Be it known that I, JOHN F. HOLLINGS, a citizen of the United States of America, residing at Hartford, in the county of Hartford and State of Connecticut, have invented a certain new and useful-Improvement in Fire-Pot Linings, of which the following is a description, reference being had to the accompanying drawings, wherein- Figure I is a view of a furnace embodying said improvement in central vertical section. Fig. 2 is a plan view of the parts shown in Fig. l. Fig. 3 is an edge View, on an enlarged scale, of one of the supporting-staves described hereinafter. Fig. 4 is a back view of the stave shown in Fig. 3. Fig. 5 is an end View of the stave shown in Fig. 3. Fig. 6 is an edge View, on an enlarged scale, of one of the tying-staves described hereinafter. Fig. 7 is a back view ofthe stave shown in Fig. G. Fig. 8 is an end View of the stave shown in Fig. 6. Fig. 9 is an edge view, on an enlarged scale, of one of the closing-staves described hereinafter. Fig. 10 is a back view of the staves shown in Fig. 9. Fig. Il is an end View of the stave shown in Fig. 9. Fig. 2 is an enlarged perspective View showing three of the staves in the position which theyoccupy when in place. Figs. I3 and 14. are enlarged perspective details of one of the tying-stavesland one of the closing-staves, respectively.
This improvement is one specially applicable to furnaces such as are commonly used for heating houses and other buildings, as well as to those which produce hot air, hot water, or steam.
In the accompanying drawings the letter 'a denotes the fire-pot of a furnace of the class already indicated.
The letter Z) denotes the grate.
The letter c denotes certain projections, such as are ordinarily found in furnaces of common construction. In the case where the improvement forming the subject-matter of this patent is readily removable from the firepot these parts 'c form the supports for the parts of the improvement yet to be described. In some furnaces there are other supports of this character to be found in ordinary constructions, and it will be understood that they can be made specially for the purpose in hand.
The apparatus shown and described herein is of the class that are made adaptable to furnaces already existing and in ordinary use.
The letter d denotes a flexible band of sheet metal with ends that interlock by a motion lateral to the breadth of the band. l It is made of such flexible material in order that it may be introduced through the door of the furnace and then putin proper place and shape. It is best that it should t snugly against the wall of the fire-pot; but in some cases, in order to avoid the necessity of having a great number of sizes of this flexible band, spurs or projections d are provided thereon, which in the act of fitting the band in place may be turned out from the band laterally as far as necessary at different points and serve as o points of contact with the wall of the fire-pot.
Whatever space there .may be between the band d and the innerwall of the fire-pot is to be filled with suit-able cement or the like. letter d2 denotes parts of this flexible band, preferably at its upper edge, which are turned inwardly to serve as a seat for the ring, next to be described.
The letter .e denotes a ring mad-e in interlocking sections-that is, interlocking at the ends, as by dovetails, as at E--a construction which permits the parts of the ring to be introduced through the door of the firepot and assembled Within.
The letters A B C denote staves,which when assembled form an inner wall somewhat removed from the wall of the {ire-pot and leaving. an air-space between them.
The letter f denotes a ring the same in construction as the ring e, it also being made in interlocking sections.
The letter g denotes an apron lying partly upon the ring f and partly upon the floor of the door-opening into the fire-pot and serving practically vas a continuation of that floor across the upper ring, and, if desired, there may be aprons h for somewhat similar use at or near the rear.
Practically-there may well Vbe four of the staves A, which I will call the supportingstaves, six of those lettered B, which I will call the tying-staves, and four of those lettered C, which I will call the closing-staves, and all of these staves preferably have their edges struck on lines truly radial from the The IOO
center of the grate and their outer faces curved slightly, so as to fit within the circles i formed by vertical rims e' and f', projecting toward each other, respectively, from the trated four such mortises (lettered f2) in the` upper ring, those in the lower ring being directly beneath and out of sight. supporting-stave A has on its back or outer face a longitudinal web A4, provided at its extremities with outwardly-facing hooks A', as best seen in Fig. 3, and at its lower end this stave also has the ange A2. Each tying-stave B has a similar web B4, with hooks Band flanges Bzat both ends. Each closingstave C has a similar web C4, except that it extends completely to the ends of the stave, and at its extremities this web is provided with dovelailed tenons C. On the outer face of this web, near its lower extremity, is a stop C2, facing toward the lower end of the stave and positioned to correspond with the tips of the hooks on the staves A and B, and the tenon C at the upper end is extended downward to a point corresponding with the throats of the uppermosthooks on the remaining staves, below which the sides of this tenon are cut out, as at C3.
In assembling the parts of this improved device the band cl, if it is employed, is first put in position, and the sections of the lower ring e are then inserted, interlocked at their ends, and supported by the seats d2 of the band. The Lipper ring j' is then put into place in like manner, and the operator is ready to insert the stave. It is obvious that each of the supporting-staves A and the tying-staves B may be brought into position opposite one pair of mortises, then moved radially outward, so that the hooks pass into these mortises, and then carried annularly around, so that the hooks take over the rims of the two rings. During this operation the iianges A2 at the lower ends of the supporting-staves pass in under the lower fringe e, as seen at the left of Fig. l, and the flanges B2 at both ends of the tying-staves B pass outside the rings e and f, as seen at the center of this View. Hence the stavesA serve to support the upper ring, which might be lifted oif of them if it were not for the staves B, whose flanges B2 tie the upper and lower rings c and f together. By preference two of the tying-staves B are brought into position across the interlocking ends of the sections of the rings, as seen at the right and left of Fig. 2, so as to hold their dovetails E from disengagement. The complete-device is built up by finally inserting the four closing-staves C at the points indicated in Fig 2. In this operation each of such closing-staves is brought into its proper radial position, but
Each
raised higher than the staves alongside and its upper extremity borne inward. This per mits the lower tenen C to pass over the rim c and drop into the mortise therein until the stop C2 strikes upon the upper face of the lower flange e outside said mortise. Before dropping the stave into position, however, the cut-out portion C3 of the upper tenon C is passed into the mortise f2 in the upper ring f, which permits the body of the stave to assume a vertical position, and then when it is dropped into place both tenons C' engage and fill the mortises in the two rings, and the body of the stave closes the opening remaining between the other staves which have previously been put in place. As so constructed it is impossible for any of the sta-ves to become accidentally displaced. In order to remove them, it is necessary to re; verse the operation just described with re* spect to one of the closing-staves, after Which the entire set can be moved around until any one is opposite a pair of mortises, and then it can be withdrawn, as will be clear.
I claiml. In a furnace fire-pot, in combination, a grate, a flexible band with interlocking ends supported from said fire-pot, a sectional ring supported on said band, staves interlocking with the ring, and a top ring interlocking the said staves, all substantially as described and for the purposes set forth.
