AM. PHOT0'LlTHO.C0.N.Y. (DSEORNES PROCESS) Uurrnn T aTns PATENT @Tirion CHARLES .I. EVERETT, OF NEW YORK, N. Y., ASSIGNOR TO LOOKVOOD 85 EVERETT, OF SAME PLACE.
IMPROVED RENDERING APPARATUS.
Specification forming part of Letters Patent No. 59,312, dated October 30, 1866.
To all whom t may concern:
Be it known that I, CHARLES J. EVERETT, ofthe city and county of N ew York, and Sta-te of New York, have invented certain new and useful Improvements in Rendering Apparatus 5 and Ido hereby declare the following to be a full, clear, and exact description of the same, reference being had to the annexed drawings, making part of this specification, in which- Figure l shows a vertical section through that part of a rendering apparatus to which one of my improvements is applied. Fig. 2 shows a modified application of said improvement 5 and Fig. 3 shows a vertical section through a relnlering-tank, to which another of my improvements is applied.
rllhese improvements relate more especially to the apparatus for which Letters Patent of the United States were granted to me on the 13th day of February, 1866, though they may be applied to any apparatus used for a similar purpose.
In that apparatus the noxious gases and vapors from the tank are-introduced to the consuming-furnace below the grate-bars, where they are left to be carried up through the tire by the draft of the consumer. This plan, although entirely successful in consuming the gases and vapors from the tank, does not-do it so economically as it is capable of being done, and especially when the tank is large, in which case there is a large quantity of steam and gas to be consumed, which not only causes a rapid current of air through the re, and a correspondin gl y-increased consumption of fuel from this cause, but the combustible elements of the superheated steam and gas also unite with the fuel, by which the consumption is still further augmented.
To obtain, therefore, acomplete consumption of the noxious gases and vapors from the tank, without increasing the consumption of fuel beyond what would take place by the natural draft ofthe consumer, is one of the objects of this improvement, which object I accomplish in the following manner-that is to say, I carry the delivering end of the supcrheater or coil A down to as near the furnace as experience may dictate, say to within about fifteen inches. I then, when the superheater is made of a coil,
as shown in the drawings, lead the lower end` of the coil through the shell of the consumer,
and connect it to a ring or coil of pipe around the outside of the furnace,in the manner shown by B, and continue the end down alongside of the ash-pit G, as shown by D. In the ring of pipe B, I set jet-tubes H H, the., and so arrange them as to cause their upper-or discharge-ends to enter the blow-pipe J J, Ste., which I adjust in the shell of the consumer at such an oblique angle with the axis of the consumer as will give the best results in accomplishing the end sought after. These blowpipes may be secured in the shell of the consumer in any convenient manner. I secure them with jam-nuts, one on each side of the shell, as indicated in the drawings; but they may be secured in any convenient manner that may suggest itself to the maker.
The `iet-tubes H should be provided with cocks, as indicated, to stop the liow of gas and steam whenever it may be expedient, and the lower end of the pipe D should be provided with a jet-tube and blow-pipe, communicating with the ash-pit in the manner shown.
The ash-pit should be fitted with a door, T, to regulate the supply of air to the furnace. Now, supposing the apparatus to bein'operation, with the steam and gas jets open, the
steam and gas, in issuing through the blowpipes, will induce a current of air to flow in along with it sufficient to support combustion over the furnace when the heat is sufficient to ignite the superheated noxious gases and vapors as they issue from the jet-tubes. By this means the consumption of the gases and vapors takes place over the furnace without auginenting the consumption of fuel.
rEhe door T may be very nearly closedindeed it may be quite closed-when the jetL is open in the ash-pit, which alone is sucient to support combustion; but when thejet L is not used the ash-pit door should be kept open just far enough to keep bright the fire in the furnace. To concentrate the heat over the furnace and insure thcignition of the vapors and gases, to arrest their too rapid ascent and give time for their consumption, I place over the fire, in -the under side of the superheating-coil, an inverted pot or receiver, It, made with a hole in its upper end, for the flame of the gases to pass through during combustion. This'receiver should be arranged near enough to the lire to keep it at a bright-redheat, and I think it best to adjust the blow-pipes J J so as to make them deliver the steam, gas, and air in the inside thereof, as shown in Fig. 2. This pot may be supported upon brackets, as shown by t, or it may be fitted with brackets to hook in thesuperheating-coil, as may be found most convenient or eflicient.
In case it should be found necessary to insure a more rapid and perfect consumption of the noxious gases and vapors, or a more economical one than can be obtained by the delivery of the jets and blow-pipes under the receiver, or immediately over the iire, I propose to arrange jets and blow-pipes, or simply airpipes, through or in the consumer, one above another, as far up as may be necessary to accomplish the desired result, as shown by N M.
Fig. 2 is a modified method of making the jet and blow pipe. The jet-pipe a in this case has a closed connection with the superheater or coil, and the blow or air tube Z is introduced through the jetpipe, so that none of the noxious gases or vapors can escape to the outside of the consumer 5 and there is, moreover, a more rapid current obtained by this method, as well as a better union or mixing of the vapor, gas, and air. In applying this method, the steam and gas tube a should be made to project beyond the air-tube, as shown in Fig. 2.
Fig. 3 shows a further improvement on the tank shown in my patent of February 13,1866. This im provcment consists in arranging in the center of the tank a pipe, P, communicating through the bottom of the tank with the waterspace Q, and through the upper part of the tank with the steam-space, as at i', in the manner shown. The object of this improvement is to increase the rendering-surface of the tank by introducing a heating-surface in the center of the mass of fat with which the tank is charged 5 and it is believed, too, that this pipe induces more or less circulation in the steam and water jacket, givin g the heating or rendering surface greater efficiency.
Now, the improvements illustrated in the drawings hereto annexedfan d described herein may be applied in a variety of ways and to a variety of furnaces. I want it therefore'understood that I do not intend to confine my claim to the particular devices, arrangements, or combination of devices herein described and shown for practicing my improvements; nor do I mean to claim the use of any principle per se but What I claim, and desire to secure by Letters Patent, is-
l. Consuming the noxious or offensive gases and vapors from a rendering tank, apparatus,
.or contrivance by introducing them in, over,
or under the furnace along with an artificial current of air induced by the flow of said steam and gas from the rendering apparatus or superheater.
2. Uniting or mixing over the furnace oi' the consumer or deodorizer an artificial current of air and the hea-t of the furnace with the noxious or offensive gases and vapors from a rendering apparatus, for the purpose of consuming them without materially increasing the consumption of fuel in the furnace.
3. The use of jets and blow-pipes, applied so .as to introduce the noxious gases and vapors, along with a current of air, into, over, or under the furnace, substantially as shown and described.
4. Concentrating the heat with the noxious gases and vapors from a rendcringtank, along with the current of air, over the furnace, and
arresting their too rapid ascent by the use of a receiver, to insure their ignition and consumption, as set forth.
5. The use ofthe pipe I, Fig. 3, in the tank, substantiallyr as in the manner described, for the purpose specified.
