8 Claims.

The main object of the invention is to provide a casing formed of panels adapted to carry sections of refractory furnace linings in such manner that these sections can be readily removed with their supporting panels, without disturbing the remaining panels and sections connected thereto.

Another object of the invention is to provide a casing for a boiler or a smoke breechlng, in

which the refractory lining requires frequent renewal, so constructed that it will only be necessary to remove a panel of the casing in order to give access to the part of the lining to be removed.

A further object of the invention is to provide for circulation of air between the casing and the refractory lining when inferior insulating material is used between the casing and such lining.

A still further object of the invention is to provide a casing, of the character referred to, which is provided with. means for maintaining the inner, vertical surface of the refractory lining in positive alignment.

Other objects will be disclosed in the specification and drawings.

Referring to the drawings, in which similar parts are designated by like numerals: 15

The wall I comprises a casing constructed of panels 3 having fianges 4 and 5 at their opposite edges, provided with apertures 6 adapted to receive bolts for the purpose of connecting adjacent flanges to each other. The lower fiange 5 has an inwardly directed fastening plate 1 spotwelded or otherwise fixed thereto.- The plate I has its outer edge turned upwardly to form a member 8 adapted to fit into an undercut rabbet 9 formed in the lower edge of the slab III of refractory material.

A fastening plate ll similar to the plate I is detachably secured to the upper flange 4 of the panels 3 by means of the bolts l2, which are used to secure adjacent panels to each other. The plate II is turned downwardly at its outer edge to form a member l3 adapted to fit in an undercut rabbet l4 formed in the upper edge of the slab Hi. When the casing is assembled, the two fastening devices are in contact with each other throughout their width to the members 8 and 13. These members 8 and I3 form in effect a dovetailed tongue seating in a dove-tailed groove formed by the undercut rabbets 9 and M of the adjacent slabs I0.

In the wall I the slabs III are located a considerable distance from the casing formed by the panels 3; and in this space insulating material I5 is secured between the fastening plates I and l I. Between the insulating material and the back wall of the casing formed by the panels 3, there is mounteda series of spacers Iii, which are U- shaped in horizontal cross section, and are arranged with the edges of their flanges in contact with the rear wall of the panels 3.

Gauge stops ll are formed on the plates I and II by stamping out the material thereof so as to position the stops to form a gauge for the purpose of maintaining the slabs III in fixed vertical position between the fastening plates. A series of apertures I! extend through the plates 1 and II in position to register with the space between the spacers i6, and the rear face of the panels I. A series of apertures iii are formed through each of the panels, near the flanges thereof, to admit air" into the spaces formed at the back of the panels by the spacers it. The holes i8 permit the air to circulate between upper and lower chambers which are formed by the spacers ii in adjacent panels. The holes I9 permit air from outside the casing to circulate in the air chamber formed by said panels and spacers.

In the wall 2, shown as connected to the wall I, the panels 3 and slabs Ill are the same as are used in the wall I. In this case, however, the insulation l and the air circulating spacers I! are omitted. The fastening devices 20 and 2| are substantially the same as the devices 1 and I l in so far as their outer edges are turned to form 20 a dove-tail tongue adapted to seat in the groove formed by the undercut rabbets 9 and N in adjacent slabs III. This construction is to be used on a breeching; and the air circulation is secured by the air passing through the apertures I9 25 and through the holes formed in adjacent fastening plates by stamping up the gauge stops 21.

It will be obvious from inspection of the drawings that whenever it becomes necessaryto remove any layer of slabs connected to any panel I, it is 80 only necessary to remove the bolts connecting adjacent panels to each other and then, by means of a hook inserted in the holes I, pull out any panel of the casing. The panel carries with it the air spacers ii, the insulation l5, and the re- SI fractory slabs III.

In the modification shown in Figure 7,the panels of the casing are the same as are indicated by the reference numeral 3 in Figures 1, 2, and 3 of the drawings. The fastening devices I2 and I! Q are shaped at their inner ends to form flanges bent to seat in the undercut rabbets of the slabs Ii. These fastening devices 82 and 38 are formed from flat plates adapted to be inserted between the flanges 4 and 5 of adjacent panels 3, and

4 to be secured in position by the usual bolts. Apertures 34 formed in the plates 82 and I} provide for circulation of air in the air space formed between the insulation 23 and the back of the panels 8.

In the modification shown in Figures 8, 9 and 10, the slab 35 of refractory material is provided, along its opposite edges, with grooves 36 and 31, adapted to receive the tongues ll formed by stamping out of the fastening plates 39 and 40. I These plates 39 and II are detachably secured between the flanges I and 5 of panels 3 which form the casing. Slabs ll of insulating material are secured between opposite plates 38 and 40 and in contact with the rear face of the refractory O0 slab 8!. Registering apertures 42 in the plates 39 and provide for circulation of air in the space between the slabs of insulation and the inner surfaces of the panels 3.

Tim modification shown in Figures 11, 12 and 1a is mums the same as that shown in Figure: 8, 9 and 10. Corresponding parts are designated by'the same reference numerals primed. In this form, however, the slab 43 of refractory material is provided, at its opposite edges, with groom M and 45 somewhat wider than the m 88 and 31, in order to receive the tongues Cl and II which are bent in substantially semicircular form at the outer edges of the plates 15 80' and 40'. It is believed the operation of he aovean various forms of this invention will be apparent to persons skilled in the art.
