DEVICE FOR REMOVING BRICKS Filed April 12, 1945 I l l mfg/k I l Wi 69k away Patented Jan. 7, 1947 UNITED. STATES PATENT OFFICE DEVICE FOR REMOVING BRICKS Wiley F. Casey, Birmingham, Ala.

Application April 12,1945, Serial No. 587,991

The invention relates to a brick remover, and

more especially, to an apparatus for removing bricks while hot from an open hearth steel furnace or the like.

The primary object of the invention is the provision of an apparatus, of this character, wherein the bricks while at white heat can be readily and conveniently removed from the interior of an open hearth furnace with dispatch, and without requiring the cooling of such bricks before such removal, which cooling requires considerable time, with resultant delay and removal by hand. This apparatus is adapted for use when it is found necessary to reline the furnace, and heretofore the brick work would be knocked down, the furnace cooled and the brick removed by hand, which required considerable time and labor, the apparatus being effective for eliminating this procedure.

Another object of the invention is the provision of an apparatus of this character, wherein the construction thereof is novel and the assembly unique, it being possessed of few parts, compact, and useable with a charging machine, for the mechanical working thereof.

A further object of the invention is the provision of an apparatus of this character, which is simple in construction, thoroughly reliable and eflicient in operation, expediting the mechanical handling of hot bricks, strong, durable, readily and easily operated, and inexpensive to manufacture and install.

With these and other objects in view, the invention consists in the features of construction, combination and arrangement of parts as will be hereinafter more fully described, illustrated .in the accompanying drawing, which shows the preferred embodiment of the invention, and pointed out in the claim hereunto appended.

In the accompanying drawing:

Figure 1 is a fragmentary diagrammatic dotted line view of an open hearth furnace with the apparatus constructed in accordance with the invention positioned therein for the removal of brick therefrom.

Figure 2 is an end elevation of the apparatus.

Figure 3 is a view similar to Figure 1 looking toward the other end thereof.

Figure 4 is a sectional view taken on the line 4-4 of Figure 1 looking in the direction of the arrows.

Similar reference characters indicate corresponding parts throughout the several views in the drawing.

Referring to the drawing in detail, particularly.

1 Claim. (Ci. 2142.6)

outline, a portion of an open hearth furnace, which is of standard construction, having a charging doorway Ill leading to and from its hearth I I, as is common in such type of furnace, and B denotes, in its entirety, the brick removing apparatus constructed in accordance with the invention and hereinafter described.

The apparatus B, comprises an elongated substantially rectangular shaped hood-like body formed with a solid straight side wall 12, opposed to the open side thereto, a straight top l3, upwardly divergent end walls M, and reversely laterally', angled to the side wall l2, and a bottom shoveling wall l5, outwardly sloping from such wall 12, the corners l6, between the latter and such bottom wall being beveled in the direction toward each other.

Integrally formed on the bottom wall 5 at the under fac thereof and at intervals throughout its extent, to protrude uniformly beyond its free edge, are scooping teeth I1, which are reversely beveled within their length 'to provide knife edge-like tips I8 outwardly of the body.

Operating through the doorway ll] of the furnac A is a rammer IE, only a portion of which is shown, of a charging machine, not shown. This rammer H) has detachably coupled therewith by a wedge jointer connection 20 the outer end of a suspension or carrier bar 2!, which through the clips 22 and bolted head 23, respectively, has securely fastened to its inner end, the body at the top wall l3, so that the charging machine in the operation thereof permits the scooping up of the hot bricks within the furnace, pulling them out of the latter, and the dumping of such bricks on the ground or directly into a railway car or other vehicle.

This apparatus B eliminates the removal of the bricks from the furnace A by hand, and does not require the cooling of the hot bricks, as they are mechanically handled by the said apparatus.

What is claimed is:

An apparatus of the kind described, comprising hood-like body having a straight solid side wall, upwardly divergent end walls, reversely laterally angled to said side wall, a shoveling bottom wall, and a straight top wall, respectively, teeth projecting uniformly from the free edge of the bottom wall, a handling bar securely fastened to the top wall of the body by means of U shaped clips and a bolt through the free end of said bar for the carrying thereof for scooping action of the same and means for detachably coupling the bar to a rammer of a charging machine.
