IMPROVEMEN IN APPARATUS FOR RENDERING LARDI TREATING OFFAL, 86 2.

Specification forming part of Letters Patent No. 136,208, dated February 25, 1873.

To all whom it may concern:

Be it known that I, JOSEPH N. B. BOND, of

the city, county, and State of New York, have invented a new and Improved Process and Apparatus for Deodorizing the Gases from Lard-Boiling and other Establishments; and I do hereby declare the following to be a full, clear, and exact description thereof which will enable those skilled'in' the art to make and use the same, reference being had to the accompanying drawing forming part of this specification, which drawing represents longitudinal vertical section of my apparatus.

This invention consists in a decomposingehamber filled with iron turnings or other suitable material, and situated in the interior of a furnace, said chamber being connected at one end with a pipe which carries ofi' the gases from a lard-boiling or other establishment of a similar nature, while the other end ofthe decomposing-chamber connects by a suitable pipe with a condenser. In this pipe extends a steam-nozzle, whereby the passage of the gases through the decomposing-chamber and into the condenser is accelerated. The

. condenser is supplied with water under pressure which is injected through a rose-head, and it also connects with a steam-pipe, which serves to blow out the sediment accumulating in said condenser. The invention further consists in the process of deodorizing gas from rendering-tanks; namely, by passing the gas, in connection with. steam, through a highlyheated chamber, containing iron filings or other suitable materials, as specified hereinafter.

In the drawing, the letter A designates a chamber made of cast-iron or other suitable refractory material, and situated in the interior of a steam-boiler furnace, B, so that it is exposed to direct action of the fire, and that the temperature of the chamber is raised to a high degree. Said chamber is filled with iron turnin gs or other suitable material, according to the nature of the gases to be treated, and it connects at one end with a pipe, 0, which serves to carry off the gases from a lard-boilin g or other establishment of a similar nature. From-the opposite end of said chamber extends a pipe, D, which leads into a condenser, E, said pipe being connected to a head, F, provided with a series of nozzles, G, which dip beneath the water contained in thecondenser.

Through the side of the pipe D extends e pipe, H, which forms a nozzle, to, in the interior of said pipe, and which connects by a pipe, J, with the steam-boiler K, so that by injecting steam into the pipe D the passage of the gas through the decomposing-chamber 7 A is accelerated. The pipe I connects with a reservoir containing water under pressure, and from the pipe J extends a branch-pipe L down into the decomposing-chamber.

The contents of the condenser are blown off through a tail-pipe, M.

When the chamber A is heated, the gaspipe 0 is opened, and as the gas comes in contact with the heated iron turnin gs or other material contained in said chamber, it (the gas) is decomposed, and a large percentage of its offensive odor is destroyed. The gases escaping from the decomposing-chamber pass through the pipe D into the condenser, which is supplied with cold water through pipe I, and thereby a large percentage of the gases is condensed. The non-condensable gases are carried through a pipe, N, beneath the grate in the furnace B, where the same are consumed. The sediment which accumulates in the condenser is blown off from time to time by injecting steam into it through the pipes J and I, the connection of the pipe I with the reservoir being closed for the time being.

By this arrangement the offensive gases generally escaping from lard-boiling or other establishments of a similar nature can be effectually destroyed, and such establishments can be worked without detriment to the neighborhood.

What I claim as new, and desire to secure by Letters Patent, isi 1. The combination of a decomposing-chamber, A, and condensers E, with a gas-coir ductor, O, pipe D, and steam generator, K, substantially as and for the purpose shown and described.

2. The process for deodorizing gas from rendering-tanks, viz., passing the gas, in connec tion with steam, through a highly-heated chamber containing iron filings or their equivalent, substantially as described.
