METHOD OF PRODUCING SMOKE FOR CURING- MEATS.

Specification of Letters Patent. Patented lay 15, 1917.

Application filed. November 16, 1916. Serial No. 131,669.

ous and uniform production of smoke with-' out ignition of the smoke-producing material.

In the present state of the art. smoke is usually produced by imperfect combustion of the smoke-producing material. It is difficult to control combustion so as to maintain uniform smoke production and the appara-- tus employed requires attention. With my improved method and apparatus the operation may be entirely automatic and without danger of igniting the smoke-producing material or variation in quantity of smoke produced. This is accomplished by the use of an electrical heating unit proportioned to limit the temperature below the ignition point, and by means for feeding the unit through the material for producing the smoke.

' In the drawings:

Figure 1. is a perspective View illustrating an electrical heating unit suitable for use with my improved method;

Fig. 2 is an elevation showing the unit in use, for producing smoke.

A is a suitable container for the smoke and material to be treated thereby. B is a pile of the smoke-producing material, such as sawdust. arranged in the base of the container, and C is an electrical heating unit, preferably initially placed upon the top of the pile and fed by gravity through the same during the operation. The unit may be of any suitable construction, but as specifically shown in Fig. 1, it comprises a frame D having depending studs E thereon, with a resistor wire or ribbon'F laced back and forth over said studs and suitably insulated. The resistor may be either exposed or armored, and the current may be supplied through a flexible conductor G.

With the construction as described in operation, when current is passed through the resistor the heat developed is sufficient to carbonize the material B and to produce the smoke, but the proportion is such as to limit the temperature below the ignition point. Consequently the material will not be ignited, but as it is carbonized the weight of the frame F will cause downward feed, this continuing until the entire pile is consumed.

While I have described an apparatushaving a gravity feed, it .is obvious thalizany means of feeding the heaterthrough the material will be equally operative.

What I claim as my invention is 1. The method of producing smoke, comprising the electrical generation of heat limited in temperature to less than'requiredfor ignition of the smoke-producing material, and the subjection of said material to said heat generation.

2. The method of producing smoke, com-- prising the electrical generation of, heat, limiting the temperature to less than the ignition point of the smoke-producing material, and relatively feeding the material and electrical heat generator to produce a continuous and uniform smoke production. 3. The method of producing smoke, com

prising the passing of an electricalv current" I through a resistor proportioned to generate in said resistor heat limited in temperature to less than the ignition point of the smokeproducing material, and feeding said resistor through the smoke-producing material.

4. The method of producing smoke, comprising the passing of an electric current through a resistor, placing said resistor on the top of a pile of smoke-producmgmatcrial, and feeding the same by gravity through said pile.

5. The method of producing smoke, comprising the generation of heat in a heater, of a temperature less than the ignition point of the smoke-producing material but sufliciently high to carbonize said material, placing, said heater on the top of a pile of smokeproducing materialand feeding the same by gravity through said pile.

In testimony whereof I aflix my signature.
