bemounted in the lining wall, saidsocket having an opening through a side of the block and being of narrowest width inits middle portion. The invention also consists in the parts and in the com` binations of parts hereinafter ldescribed and claimed. Y

Fig. '7 is an isometric projection of the metal member of my anchoring device.

As illustrated in Fig. 1, certain types of furnaces are built with an outer wall I, which is usually made of brick, and an inner or lining wall 2 inside thereof and in contact therewith. The lining wall is usually built of refractory plastic material or refractory concrete or a mixture of high temperature cement and calcined grog or of refractory blocks. The lining wall is exposed to intense heat that causes expansion and contraction thereof and to transverse stresses that make it desirable to anchor the lining wall to the outer wall in such a manner as to be steadied against bulging or distortion due to excessive transverse or vertical movement and still leave 7 claims. ((11.72-101)` the lining'w'all free to expand and contract in dependently of the outer wall.

According to the present invention, my anchoring means comprises two main parts, namely, a-

refractory block Il adapted to' be mounted inthe lining Wall and a metal Vmember 5 with one end 6 engaged in a socket 'I provided therefor in said refractory block and with an eye 8 in its otherv end 9 adapted to loosely engage a hook Ill providedtherefor'in the outer wall.

The refractory block is preferably pyramidal 0r wedge-shaped and its sides are preferably formedwith ribs or depressions Il so as' At'o make interlockingengagement with the refractory con'- creteA or plastic material in which the block' vis embedded when the Wallis built. In practice, the "concrete wall is built up and hammered, rammed or poured to a suitable height and then the refractory block or blocks are placed in position thereon with their small ends spaced from the outer wall and with their end portions covered with cardboard 2| to prevent the plastic concrete from coming in Contact therewith. Then the p'ouring,'ramming or hammering of th refractory material is resumed to raise the inner wall and embed the refractory blocks therein, In this way, the small end of each block' projects into one of the vrecesses 3 thus formed in the outer face of the inner wall. Y'

Ihe smallen'd portion I2 of the refractory block is provided with the socket 1 that opens through the small end of theblock. The Yside walls I3 vof this socket converge from eachv end of the socket to forma relatively narrow throat' I4 connecting inner andout'er triangular recesses I5, I6.

' The metal member 5 is similar in shape to the socket 1; that is, the metal member has a relatively narrow middle portion I'I that fits loosely in the throat of the socket, and the sides I8 of its inner end diverge to Iit loosely in the inner triangular portion I5 of said recess, and the outer end I9 of the metal member has diverging sides that t loosely in the outer triangular portion I6 of the socket. This outer portion of the metal member has the eye 8 formed therein to loosely receive the vertically extending metal hook l0 that is mounted in the outer wall. As illustrated in the drawing, the converging faces of each side yWall I3 of the socket 1 approach each other at an angle of the order of ninety degrees and the middle portion I4 that connects them is short and more or less rounded. The converging faces of the sides I8, I9 of the metal member also make an angle of the order of ninety degrees with each other and the neck portion between them is short.

This design affords a wide bearing at the inner end of the metal member in the socket 'l and enables the hook receiving opening 8 of the outer end to be made wide enough to permit considerable play between the metal member and the hook. It is noted also that along with these advantages is the fact that the metal member is short enough to permit the main and lining walls to be disposed close together.

AS the inner end of the metal member 5 is wider than the throat of the socket 1, the socket is extended through the top ofv the refractory block so that the metal member can be entered into the socket through said opening in the top of the block. As shown at 20, the bottom wall of the socket terminates short of the side walls thereof so as to accommodate the metal hook of the outer wall.

In operation, the metal member is adequately supported by the refractory block in which it is mounted and it is also kept thereby in position for cooperation with the metal hook of the outer wall. Thus the inner'wall is free to expand and contract vertically independently of the outer wall and still it is effectively steadied by the anchoring means against distortion due to excessive movement of the inner wall.

What I claim is:

1. A refractory wall-anchor block with converging sides, said block having a socket opening through its small end and through a side of said block, those side Walls of the socket that are next to the open side of the socket converging from each end toward the middle to form a relatively narrow throat in the middle portion of said socket connecting inner and outer triangular portions.

2. A refractory wall-anchor block with converging sides, said block having a socket opening through its small end and through a side of said block, those side walls of the socket that are next to the open side of the socket converging from each end toward the middle to form a relatively narrow throat in the middle portion of said socket connecting inner and outer triangular portions, and the side of the block opposite the side that is open to said socket terminating short of the ends of the adjacent sides.

3. A refractory wall-anchor block with converging sides, said block having a socket openf ing through its small end and through a side of I said block, said socket being narrowest in its middle portion, and the side of the block opposite the side that is open to said socket terminating short of the ends of the adjacent sides.

4. A wall anchoring device comprising a block having a socket in one end and a metal member with a portion extending into and loosely mechanically interlocked with the socket portion of said block, said socket being open at the top and being narrower in its middle portion than at its ends and the metal member comprising a narrow middle portion that nts loosely in the middle portion` of said socket, a wider end portion that ts loosely in the inner end portion of the socket and a relatively wide outer end portion that projects beyond the end of the block and has an eye extending vertically through it.

5. A Wall anchoring device comprising a refractory block with converging sides having a socket extending through its small end, and a metal member with a portion extending into and loosely mechanically interlocked with the socket portion of` said block, said socket being open at the top and being narrower in its middle portion than at its ends and the metal member comprising a narrow middle portion that ts loosely in the middle portion of said socket, a wider end portion that fits loosely in the inner end portion of the socket and a relatively wide outer end portion that has an eye extending vertically through it, the eye portion of said metal member extending outwardly beyond the end of the bottom of the socket.

6. A wall anchoring device comprising a rcfractory block having a socket in one end and a metal member with a portion extending into and loosely mechanically interlocked with the socket portion of said block, said socket being open through one side of the block and being narrower in its middle portion than at its ends, and the metal member comprising a narrow middle portion that ts loosely in the middle portion of said socket, a wider end portion that fits loosely in the inner end portion of the socket and a relatively Wide outer end portion that has an eye extending through it in position to receive a wall hook.

'7. A wall tie for anchoring a lining wall to the outer wall of a furnace, said tie comprising a relatively short and narrow middle portion with concave sides and relatively wide end portions whose adjacent sides converge toward each other at an angle of the order of ninety degrees and merge into said concave sides of the middle portion, one of said end portions having a wide opening for a wall hook, whereby said wall tie is adapted to interlock loosely with a socket of like shape in an anchor tile and to interlock loosely with a wall hook.
