UNITED STATES PATENT OFFICE Application March 24, 1933, Serial No. 862,495 8 Claims. (01. 299-46) This invention pertains to an apparatus for the best mode so far devised for the practical treating coal with oil, to render the same subapplication of the principles thereof. stantially dustless during subsequent handling. In the drawing:--

I am aware that it is old to treat coal with oil, Figure 1 is a plan view of an apparatus con- 5 but the apparatus heretofore employed has been structed in accordance with one form of the pres- 5 cumbersome, costly, and extremely ineflicient. ent invention; and Therefore, the present invention has primarily Figure 2 is an elevation with parts thereof for its object to provide a comparatively simple broken away and in section to more clearly illusand inexpensive apparatus for the treatment of trate the structural details.

Likewise, the invention may be con- 15 desired viscosity for the most efficient atomizastructed in one or more units and of various'sizes tion, regardless of inherent viscosity of the oil and capacities without departing from the prinused, or the atmospheric temperatures enciples thereof. countered.

the present invention constructed according to Obviously, the valve 10 permitsa portion of the 55 discharge line and consequently the pressure line and nozzles, while the excess oil is by-passed through the valve and returned to the tank through the line 11'. In the event that the nozzles are cut oiT, then all of the oil is returned to the receptacle and circulated therethrough.

The pump 5 is actuated by an electric motor 12, connected directly therewith through the shaft 13, which is provided with the usual flexible connection 13 of any conventional design.

In order to pre-heat the oil, and reduce the same to the desired viscosity for more eflicient atomization under any temperatures, an electric heating element 14 is inserted into the receptacle 1, and is provided with a protruding head 15, which carries the terminals to which the circuit wiring is connected.

While various controls and circuits may be employed for the motor 12 and the electric heating element 14, a preferred form is illustrated, in which a three-step switch 16 is connected with the supply circuit 17, and the heating element 14 through the circuit 18, to provide for a variable heat in the element 14, which is submerged in the oil contained within the receptacle 1, a thermocircuit breaker 19 is connected in the circuit 18 and inserted into the tank where it is aifected by the temperature of the oil contained therein.

Likewise, in order to prevent overheating and burning out of the motor 12, the same is provided with a thermal switch 20, which automatically breaks the motor circuit 21 in the event that the motor becomes overheated.

For the purpose of convenience the receptacle 1 may be provided with a suitable adjustable bracket 22 provided with a clamp 23 for reception of the nozzle fitting 7', thus permitting the same to be held in the desired adjusted position for the discharge of the oily vapor upon the coal either in a bin or traveling through a conveyor.

From the foregoing explanation, considered in connection with the accompanying drawing, it will be quite apparent that an exceedingly simple, compact, and comparatively inexpensive apparatus has been provided for the atomization of oil, particularly adapted for the treatment of coal, to render the same dustless during subsequent handling.

Obviously, pre-heating of the oil reduces its viscosity so that the same may be most efficiently atomized regardless of atmospheric temperatures, and regardless of the inherent viscosity of the oil utilized, thus effecting a material economy, not only in consumption, but permitting use of the heavier and cheaper grades of oil.

It will further be seen that extremely simple means has been provided for controlling the discharge or atomization of oil to a high degree of certainty, regardless of variation in pressure exerted thereon, and due to the fact that a portion of the oil is continuously returned to the tank 1, and circulated in contact with the heating element 14, a material economy in heat is effected, and viscosity of the oil is reduced in a minimum period of time.

While the heating element 14 has been shown and described in connection with the circulating tank 1, it is to be understood that the same may be applied to the storage receptacle from which the oil is drawn. Also, instead of by-passlng and returning a portion of the oil to the tank 1, the same may be returned to the storage receptacle without departing from the principles of the invention.

oil from the pump 5 to be forced through the In the application of the present invention the same may be installed in connection with a bin or hopper to treat the coal contained therein, or the same may be positioned over a delivery chute or conveyor to discharge a vapor or mist upon the coal as the same travels therethrough, it being understood that the volume of discharge can be readily controlled through the selective use of the nozzles 8 and regulation of the valve 10, whereby any amount of oil desired in proportion to the quantity of coal to be treated is available.
