Claims.

This invention relates to supporting means, and has to do with means for supporting linings for furnace walls and analogous structures.

My invention is directed to supporting means 5 of the character stated comprising a shelf-like member and a cooperating anchor member intended for securement in a Wall, the anchor member having simple and highly efficient means whereby it may be secured in position with eX- pedition and facility.

More specifically, the anchor is so constructed as to provide highly efficient means for supporting, at its inner end, a cooperating member, the anchor being provided at its outer end with elements adapted for cooperation with a securing member or for cooperation with the corresponding element of a similar anchor member, whereby a variety of conditions encountered in practice may be met in simple and efficient manner. Further objects and advantages will appear from the detail description.

Figure 12 is a sectional view taken substantially on line |2-l2 of Figure 11, the wall anchors and associated parts being shown in plan.

The wall anchor and associated shelf member are shown more clearly in Figures lto 3, inclusive; The wall anchor comprises a body l 5 of elongated rectangular shape in plan provided. at one end, which may be termed the inner end for purposes of description, with an integral-depending ange I6. An upwardly tapering stud il of frusta-conin cal shape is integrally connected to flange l and spaced inward therefrom by a web element I3, the upper portion of which extends'outward along the upper face of .body l5v centrally thereof. Stud I'l is provided with `a lower base flange i9 projecting radially outward thereof. A shelf member 2B, conveniently of rectangular shape in plan, is provided, adjacent `its outer side, with an integral depending socket member 2i from which extend reinforcing ribs 22 projecting radially from socket member 2t and tapering upward in height, these ribs' being integral withv the shelf and the socket member. Socket member 2| is open at bothits upper and its lower ends and defines an interior upwardly tapering socket 23, which is somewhat larger than the stud I1, socket member 2| also being provided with an outwardly flaring lengthwise slot 2t at the outer side of shelf member 2G. The width of slot 2li is appreciably greater than the transverse thickness of web element i8, thus providing clearances between the side walls of slot 2li and the web element i8. When the shelf member 223 is applied to stud l1, as in Figure 3, it rests upon base flange I9 of the stud and is free from the latter for relative movement both lengthwise and transversely, due to the clearance provided by the socket 23, whereby the shelf member is capable of movement relative to stud il for accommodating expansion and contraction of the lining supported by the shelf member, as will be dem 50 scribed more fully later.

Body l5 of the anchor is provided at its other end portion, which may be termed its outer end for purposes of description, with a lengthwise slot 25 yforming two parallel arms 263 of equal Width. 55`

Each arm 2B is provided, at its outer end, with an upwardly extending ange element 21 of greater width than the associated arm and projecting beyond the inner and the outer edges of the arm. Each flange element 21 preferably is connected to the associated arm 26, adjacent the inner edge thereof, by an integral fillet element 28.

II'he anchor and the shelf member of Figures 1 to 3, inclusive, are particularly suitable for supporting a refractory lining for a furnace wall or other structure, though they may be used to advantage for other purposes. In Figure 4 I have shown fragmentarily a refractory lining anchored to a wall by suitable anchor means a of a character to permit expansion and contraction of the lining in all directions in a plane parallel to the inner face of the associated wall, the anchor means a preferably being of the character disclosed in Patent No. 1,828,618, issued October 20, 1931, to Ivon S. Pieters, for Anchor for furnace lining. Lining L is initially formed from plastic material and is constructed in monolithic form, being later separated into sections Z which may expand and contract individually, with the object of avoiding stresses such as would occur if the lining were of considerable extent and of monolithic structure. Each of the sections Z of the lining L rests upon a suitable number of shelf members 2U so as to be supported thereby, each of the shelf members being mounted upon a wall anchor in the manner above described.

In Figures 5 and 6 I have shown a brick wall W, which may be considered as the setting or casing wall of a furnace, at the inner face of which is disposed a lining L of refractory material, such as that above referred to, such lining being separated into sections l. Each section l of the lining is supported by a suitable number of shelf members 20, each mounted upon a wall anchor imbedded in the wall W, flange I S of this anchor extending downward from body I5 thereof and seating against the inner face of the furnace wall. A securing member, conveniently in the form of a bolt 30, extends between ange elements 21 at the outer end of body I5 of the anchor, this bolt being provided at its inner end with a squared head 3| which engages in front of the inner edge portions of flange elements 21, th-eshank of bolt 30 passing through a slot 32 between the inner edges of the flange elements.' Bolt 30 extends outward beyond wall W, a suitable distance, and receives a nut 33 screwed thereon, there being a washer 34 interposed between this nut and the outer face of the furnace wall. In cases where a stay is disposed at the outer face of the furnace wall, as is commonly done, bolt 30 may be passed through the stay, upon the outer face of which the nut 33 may seat, as will be obvious. The flange elements 21 and bolt 30 provide simple and efficient means for securing the anchor in position in wall W.

Referring further to Figure 3, it will be noted that the width of slot 25 is slightly greater than the width of the respective flange elements 21, and the width of slot 32 is slightly greater than the width of the respective arms 2G but is considerably less than the width of th-e respective ange elements 21. Due to that arrangement, a second wall anchor similar to that shown in Figures l and 3 may be readily attached to the outer end of the latter wall anchor, by inserting one arm 25 of the second anchor through slot 32 of the rst anchor, so that a flange element 21 of the second anchor is disposed in overlapping relation to the ange elements 21 of the rst anchor. That may be accomplished either by moving the arm 26 of the second anchor downward through slot 32 of the rst anchor, or by inserting one flange element 21 of the second anchor through slot 25 of the first anchor, moving arm 26 of the second anchor upward through slot 32 of the first anchor.

In Figures 7 and 8, there is shown a wall W1 of brick construction which may be considered as av center or an intermediate wall of a furnace construction, in which combustion chambers are provided at opposite sides of wall W1. This latter wall is provided, at each side thereof, with a refractory lining L divided into sections Z. These sections of the lining are supported by shelf members 20, as before. The wall Wl is of considerably less thickness than the wall W of Figures 5 and 6, being approximately eight inches in thickness, it being noted that the body I5 of the wall anchor is approximately four inches in length, usually somewhat greater. In the construction of Figures '7 and 8, the wall anchors are arranged in pairs, with a flange element 21 of rone anchor disposed in overlapping relation to the flange elements 21 of the other anchor, and an arm 28 of the first anchor extending through slot 32 of the second anchor, as shown in Figure 8. In that manner the two wall anchors are effectively locked together so as to be held against relative movement toward the sides of wall W1. The anchors secured together in this manner support the shelf members 20, the latter supporting the sections Z of the lining L, in the manner previously described.

In the construction shown in Figures 9 and 10, wall W2 comprises an inner portion w formed of hollow tile, a coating w1 of suitable thermal in-v sulating material and a sheet metal sheathing wz. Sections Z of lining L, at the inner face of wall W2, are supported by shelf members 2li mounted upon wall anchors imbedded in wall W2, each of these anchors being secured against inward movement by a headed bolt 35, upon the outer' end of which is threaded a nut 36 bearing against the outer face of sheathing w2.

The construction shownin Figures 11 and l2 is quite similar to that shown in Figures 7 and 8, except that the wall W3 is considerably thicker than wall VW, being approximately twelve inches in thickness. Assuming that the body portions of the wall anchors are' approximately four inches in length, or somewhat greater, it will be apparent that when two anchors are imbedded in wall W3.-

in alignment, with flanges I6 disposed at the opposite sides of the wall, the ends of these anchor members carrying the flange elements 21 will be spaced a considerable distance apart. Under such conditions, the adjacent ends of the anchor members may be secured together with expedition and facility by means of a bolt 38, provided at one end with a squared head 39 and having a squared nut 4!) threaded onto its other end, the shank of this bolt passing through the slots 32 of the aligned anchors, with head 39 in overlapping relation to flange elements 2'! of one of the anchors and nut 4I] in overlapping relation to the ange elements of the other anchor.

It will be seen, from what has been ysaid above, that the Wall supporting means of my invention is particularly suitable for use with walls of various constructions and thicknesses, and that the anchor member is readily adaptable to various conditions of use, such as are frequently encountered in practice. Within the broader concepts of my invention, the anchor member may be used for supporting either a shelf member or any other desired member, to suit requirements. It will be understood that changes in construction and arrangement of parts of my invention may be resorted to, without departing from the field and scope thereof, and I intend to include al1 such variations, as fall within the scope of the appended claims, in this application in which the preferred forms only of my invention have been disclosed.
