A, is the top of the kiln, A¹ the upper exterior wall and B, the base on which it
rests. B is the channel passing downwardly, for example, through the middle of the
kiln and out to the smoke stack. B2, is a branch in such channel leading from the
auxiliary furnace B³.
Three pipes pass entirely round the kiln the upper is marked C, the next C¹,
and the lower C².
The pipe C¹, connects with a coil C³, and this with a pipe C³,
which leads from the compression chamber and supplies fluid under compression
to the pipe C, the same being introduced as indicated by the arrow. The pipe C²,
passes entirely round the kiln and in like manner connects with the coil C, which is
supplied with air as indicated by the arrow through the exterior pipes C6. C, is an oil
pipe passing around the kiln and is supplied from the distant oil tank by means of the
pipe E¹, through which the oil passes in the direction indicated by the arrow.
D, D, D, are fluid feeding compound valves connected each with the three pipes C, C¹,
and C. Each of these valves is connected from above with the pipe C, by the short
pipe D', each is connected with the pipe C¹, by the shorter pipe D2, and each is con-
nected with the pipe C2, by the short curved pipe D³. Each of these pipes may be
controlled by a valve if desired. E, E, are the hand pieces of such valves, and F, are
the nozzles through which they discharge into the chambers G, formed by the curved
walls H, H. J, is a similar valve having the handle J, and the nozzle J2, and this
valve is connected by the pipe Js, with the oil pipe C. By the pipe J, with the com-
pressed air pipe C, and by the pipe J5, with the atmospheric air pipe Co. The pipe C,
is used to introduce oil into the various discharge valves, the pipe C¹, to introduce
fluid under pressure and the pipe C², to introduce the atmospheric air when desired
By the various arrangements of the valves and the structure of the discharge com-
pound valves D, and J, any number of the three fluids may be commingled and
discharged at any desired point upon the kiln and in such relative quantities as may
be desired by the operator. It will be clear that considerable alteration as to the
form number and operation of the parts might be made without departing from the
spirit of my invention.
A10, is a hand wheel passing through the stuffing box B20, and screw threaded into
the piece Co, and terminating in the point D10, which passes into the passage or
nozzle Es, and controls it. Fo, is the body of the device into which the piece C¹º, is
screw threaded. This body F10, terminates in the feed or discharge nozzle G10.
Within the body F10, is a cavity shaped as shown into which opens the fluid fuel
D

page_text: Into the con-
way or passage H, and the air way or passage J. Within the piece C¹º, is a
cavity K10, into which opens the forcing fluid passage L10. In the enlarged lateral
portion F1, of the body F10, is an oil reservoir M10, which opens into the conical
shaped aperture N10, into which opens the oil feed passage H10.
cavity Mio, opens the supply way O. Within the conical aperture N10, is placed
the plug P10, having about it the spiral passage way R₁0. This plug is provided
with the spring handle S1, which has a feather T10, on its lower outer extremity
the same adapted to engage notches about the periphery of the fixed graduated
quadrant U10. The quadrant may be graduated as desired and it serves as a scale
with which to measure the extent of opening of the fluid fuel supply aperture H10.
It will be readily understood of course that the fluid fuel way 010, the forcing fluid
supply way L10, and the air supply way J1, may be controlled by suitable valves
of the ordinary construction.
A20, is an oil tank situated for example at a distance from the room in which the
furnace is located having if desired a vent tube A", and a pipe A22, leading from
near the bottom of the tank to the steam pump A23. A24, is an oil pipe leading
from such pump to the reservoir A 25. From near the top of this latter reservoir
and preferably from below the point of its connection with the pipe A24, leads
the pipe A26, back to the oil tank. B20, B20, are the boilers having the steam
domes B21, B2, and fire doors B22, B22, opening into the furnace into which leads
the oil pipe C20. This pipe connects with the pipe C", which leads from the bottom
of the reservoir A25. S20, is a steam pipe leading from the steam dome to the
pump. to actuate the same. From the junction of the pipes C20, and C21, leads the
short pipe D20, (Figs. 9 and 10) containing the gate valve E20, which is operated
by the reciprocation of the stem E21. The pipe D20, opens into the pipe A.
The stem E, is secured to a lever F20, which is pivoted at the point G20, on the
standard H20, and the other end of which engages the nut J20, on the stem K20,
of the globe valve L2. This globe valve is operated by the hand wheel M20. The
spring T20, retracts the lever F20, so as to normally close the gate valve E20 U20 is
a box which contains the device shown in figures 9, and 10. The stem of the globe
valve L20, projects through the aperture U2. The operation of my device is readily
seen; alluding first to the valve shown in figures 5, 6, 7, and 8. By operating the
hand wheel A10, the point D10, will be retracted a supply of steam discharged through
the aperture E13, out through nozzle G, and a quantity of air will be drawn
through aperture J10, and a suitable quantity of fluid fuel or oil from the reservoir M10,
through the spiral R10, about the plug P, through the passage way H10, thence
out through the nozzle. The three fluids being commingled and discharged. The
device is applicable to any kinds of fluids. By referring to figure 8, it will be noticed
that by turning the plug P10, the extent of the communication between the spiral R10,
and passage H10, will be varied and by adjusting the parts properly, the extent of this
opening and hence the quantity of fluid fed may be indicated as well as regulated by
the hand lever S10. Burners constructed somewhat in this manner could be employed
in connection with the devices indicated in figures 9, 10, and 11. In this case the oil
is drawn up by the pump from the tank into the reservoir and should the pump supply
more than is needed it will pass back through the pipe into the tank hence the oil will
be fed from the reservoir to the burners inside the furnace solely by gravity and by
the weight in the reservoir which is constant, as the oil in such reservoir has a
constant height. By operating the hand wheel which controls the steam supply to
the pump as will be seen by referring to figure 9, a lever is moved on its pivot so as
to open the passage way from the bottom of the reservoir through to the tank and
thus permit the reservoir to be entirely drained. In this manner the oil is fed to the
furnace by constant gravity pressure and a very small supply of oil is held in
proximity to the boiler. By operating the hand wheel M20, the valve S20, will be
closed when the valve E20, is opened and vice versa. Thus the oil is drained from the
reservoir when the pump is stopped and the drain is closed while the pump is in 5
operation. It is desirable in drying and burning brick and the like, that they should
first be dried and then burned and that the drying should take place with no great

page_text: heat being used and also without the products of combustion being spread over the
bricks. After having been dried it is then desirable that great heat should be applied.
If the brick in the first instance are subjected to the actions of the products of com-
bustion they are likely to be coated so as to interfere with the process of drying if
they are subjected to great heat, they are likely to crumble and be otherwise injured.
By my kiln it will be seen that it will be possible in the first place to introduce
atmospheric air alone through the various discharge nozzles, if that be desired, the
same passing up into the kiln about the brick, down through the channel B¹, and into
the stack of flue; it will also be possible to supply this atmospheric air under greater
or less heat, the same being generated in the chamber B through which such
atmospheric air passes by means of the coil; it will also be possible by
opening the valves in the pipe C+, to supply either alone along with atmospheric
air any quantity of compressed air, or fluid, in like manner, this also being heated
in the auxiliary furnace B. After this hot air either atmospheric or under
or both combined has been passed through the brick or kiln for a sufficient length
of time to thoroughly dry the brick or contents of the kiln, the brick may be burned
as follows. A current of oil or fluid is introduced by operating the valve of the
pipe E¹, (Fig. 1) and the suitable valves in pipes D¹, D', or in the compound valve into
each of the discharge nozzles where it is caused to burn together with suitable
quantities of atmospheric air or air under pressure or both. The compound valve
or burner J, is supplied with oil by the pipe J³, from the pipe C7, with fluid under
pressure by the pipe J, from the pipe C4, and with atmospheric air if desired by
the pipe J5, from the pipe Co. The valve proper of the compound valve as operated
by the handle E, controls the pipe D2, D2, and J4, respectively.

The burner nozzle or valve shown in Figures 5, 6, 7, 8, is used in the devices
shown in the other figures and when objection is made to having quantities of fluid
fuel near the point of consumption and to feeding the same by a forcing pump direct
the construction shown in figures 9, 10, 11, must be used. Hence I have shown a

kilns.
