the box allows the heat to dissipate quite freely. One object of this invention is to provide a form of box which can be quickly and easily erected or taken down and which can be used many times. Another object is to utilize the heat given off by the kiln. Ac-

- cording to this invention the box is formed of a plurality ofhollow slabs or boiler units filled with water and the steam generated in these units is led away to be used in the ovens where bricks are dried preparatory to the unit.

In the drawings Fig. l is a side elevation of one corner of a brick kiln constructed in accordance with the invention;

Fig. 2 is an enlarged view in elevation of the ends of one of the units in thebottom tier; while i Fig. 3 is a horizontalsection on tl1e-.ine of the peep holes through the unit shownin Fig. 2, the view being'taken on the line 33 of Fig. 2 looking in the direction ofthe arrows.

Referring to the example shown in the drawings, the bricks 5 are piled up in the usual manner leaving the arches 6 through the kiln as usual. V s

For the purpose of inclosing the bricks and saving the wastage of heat the kiln is inclosed by a plurality of hollow slabsor boiler units consisting of sheets 7' of boiler plate iron with L irons 8 forming the-edges of the units; These are. all held together by staybolts 9 passing through from face to face of In orderto permit access to the arches 6 in the brick and to permit the in sertion of the usual oil burners 10, certain of the slabs have openings 11 in them at their lower edges. These are adapted to register with the arches 6 of the brick though they are preferably not quite as large as the At these openings lltheL irons arereplaced by curved plates 12 welded to the boiler plate'sheets 7 which form the two faces of the unit. These curved plates 12 can project inwardly from the main unit in order to make better connection with the arch in the brickf Spy holes 13 are provided I just above the openings -11 registering with. the top of the corresponding arch in the brick. p 1

With individual units of this type it is possible to make a kiln which is higher than usual and for convenience in handling the individualunits, I therefore use a plurality of tiers oft-he units. Thus in the drawings I I have shown a lower tier 14 and above it an upper tier 15. Means are provided to hold the units of the upper tier in position on the units of the lower tier, these means includingangle' irons 16 and lugs 17. One leg of each angleiron 16 extendsoutwardly from the face of the slab and comes opposite and near to the angle iron of the vertically adjacent. slab. These legs have holes therein and a pin 28 canbe dropped through these two holes which will hold the angle irons and the units. The lugs 17 also assist in keeping each unit inlline with thevertically adj acent' unit, and if desired these lugs may have openingsl?) in their ends which project beyond the unit in order thata crane may be p used to carry the unit when the box is being built or taken down. The four walls of the box are preferably sloped inwardly as shown in Fig. 1, this meaning that the units ateach corner are irregular in shape. j the units extend a foot or so above the bricks in order that the top bricks may be properly burned. v

To supply oil and air to the burners 10in the arches, .inanifolds 20 carried inside an asbestos lining 21 may be provided outside the units, and smaller pipes 22 leading from these manifolds to each burner, there being the usual valves 23, unions, nipples, etc., as

necessary.

The units are easily and quickly assembled and disassembled and resist the heat of the kiln through many firings. i

In order further to preserve the units from the heat, I use them to generate steam and Preferably carry the steam off to an adjacent drying oven where the pipes are led underneath the drying chambers in which the bricks are being dried preparatory to burning. This does away entirely with fuel consumption for the drying process. To achieve this end I providea water inlet 24 OI a plurality of them-in the lower tier at the bottom of the units, Preferably there is one water inlet in each wall of the box. I provide a steam manifold 25 connected to the top of each unit by a pipe connection 26 and a safety valve 27. The units can be interconnected in any desired manner but I prefer to provide a connection between each unit and the units on each side of it to give complete circula-- tion. The water level should preferably be kept part way up the top tier and preferably a water gauge 28 is provided to insure the maintenance of this level uniform andalso even all around the box. To make these connections between adjacent units, openings 29 and pipe connections are provided in each corner of the slab.

VV'li-at I claim'is:

1. A brick kiln having a box comprising a plurality of hollow units adapted to contain water, and means adapted to carry off I from said units the steam generated therein.

2 A brick kiln having a box comprising a plurality of hollow boiler units having a plurality of tiers, pipe connections between the tiers. and pipe means connected to the top tier adapted to carry off the steam formed therein. I p

3. A brick kiln having a box comprising a plurality of hollow iron slabs, said slabs being arranged in a plurality of tiers, means on said slabs adapted to hold each tier in position'on theone below it, and a plurality of pipe connections between the tiers, in combination with a steam manifold connected to the slabs of the top tier, and a water inlet in a unit in the bottom tier of the box.

4. A brick kiln having a box with sloping walls consisting of a plurality of boiler slabs,

' said slabs being arranged in a plurality of tiers, means on said slabs adapted to hold each tier in position on the tier below, a plurality of pipe connections between the said two tiers, a steam manifold connected to the top of the slabs of the top tier, and a water inlet in a unit at the bottom tier ofthe box.

5. A brick kiln having a .box comprising a plurality of hollow slabs adapted to be placed about the bricks in a plurality of tiers, pipe connections between the tiers, a steam manifold connected to each slab of the top tier and a water inlet connected to the bottom tier, in combination with openings in the slabs of the bottom tier adapted to register with the arches in the brick.

6. A brickkiln having a box comprising a plurality of hollow slabs adapted to be placed about the bricks in a plurality of a hollow metal slab, bracing means fastening the two faces of said slabs, openings for pipe connections at each corner of said slab, and means at the'upper edge thereof for holding an adjacent unit in position on said first unit.

In testimony whereof I have signed my name to this specification.

DAVID J. STRICKLAND.
