products from shale rock. And the apparatus is designed to be used wherever the application of heat to the material acted upon by the heat and accompanied by a simultaneous stirring of the material together with a continual grinding or pulverizing of the material during the time that the heat is applied is desirable. l

It is the primary object and lpurpose of this invention to produce an apparatus by means of which the process above outlined may be very economically carried out. A further object of the invention is to produce an apparatus which is capable of withstanding the severe usage to which it is put during service and one particularly capable of withstanding thev high temperatures which are used with the same, as well as any other objects and purposes not at this time specifically stated but which will appear fully and 'in detail as understanding of the invention is hadfrom the accompanying drawing in which,

Fig. 1 is a longitudinal vertlcal section of the apparatus of my invention.

Fig. 2 is an end elevation of the same looking at the structure shown in Fig. 1 from the left, and

Fig. 3 is a transverse vertical section through the construction shown in Fig. 1.

Like reference characters refer to like parts in the different figures of thev drawings.

In the construction a cylindrical drum 1 of suitable metal is used open at both ends and covered with heat insulating material 2 which may be brick or equivalent material. Against the ends ofthe cylinder 1 circular heads 3 may be placed which completely close the open ends of the drum. A hollow shaft 4 passes through the heads 3 and is supported by suitable bearings at the upper ends of posts 5 located at each end of drum. A pulley. r6 is fastened to shaft 4 and is adapted to be driven by a belt 7 from any suitable source of power. Water is supplied by a pipe 8 to one end of the 1924. serial No.' 696,485. t

hollow shaft 4, the amount thereof being controlled by manually operated valve 9 in pipe 8, the water passing through the pipe and through shaft 4 and being carried away through any suitable waste pipe 10 at the opposite end of the shaft 4.

A plurality of bars 11,*in the present apparatus shown as four in number, though this number may be changed, extend lengthwise through the cylinder 1 closely adjacent the inner walls thereof and pass through openings in the head plates 3. The bars are placed 'around and are connected to metal rings 12 which are located in spaced apart relation' within the drum 1. Coiled springs 13 are mounted uponthe outer ends of the bars 11 and are held between the outer sides of the head plates 3 and pins 14 which pass through the bars 11. These springs under compression serve to press the head plates 3 against the ends of the drum' 1. It will be noted that the bars 11 are formed with one edge brought to substantially knife point and with the movement in vthe direction indicated by the arrow in Fig. 3, said bars serve as Scrapers to keep any of the material introduced into the cylinder 1 from baking against or otherwise becoming secured to the inner walls of the drum, the movement of the bars causing a continual stirring of the material within member 1. The head plates 3 are provided with gear teeth 15 around the same. Two shafts 16 and 16al pass through the covering material 2 to which pinions 17 and 17a are xed, these pinions being in mesh with the teeth 15. The location of the shafts and pinions is best shown in Fig. 2, the end plates 3 bearing thereon. Said shafts 16 and 16n are supported adjacent their ends by suitable posts 18.

A small pulley 19 is fixed on the hollow shaft 4 around which a belt 20 passes, the belt also passing around a pulley 21 which is attached to one end of a short shaft 22 and vwhich, through an intermediate gear reduction in the housing 23, drives another shaft 24 at reduced speed. The'shaft 24 is cony the speed of potation ofthe hollow shaft 4 whenever the apparatus is in use, and such rotation of the plates 3 serves to move the scraping bars 11 at a comparatively. slow rate of speed.

The hollow shaft 4 is covered the greater portion of its length' within the drum by suitable protective material which may -be placed within outer sleeves 26. At spaced apart distances on the shaft 4, plates 27 are located between the ends of the sleeves 26, each having radially extending arms through which rods 28 pass. Beaterjbars 29 are mounted on the rods 28 by means of short links 30 which are pivotally connected to the rods 28. A plate 72, as shown in Fig. 1, may be mounted eccentrically on the shaft 4 and bars, somewhat curved attached thereto at one end by means of small brackets 31 and at the other end to the adjacent plate 27. The construction may beused to aid in feeding the material from the point where it is entered into thel apparatus toward the discharge end thereof.

The material to be treated may be passed into the drum 1 through an inlet pipe 32 adjacent which is a second pipe 33 for the introduction of heated air or' other source of heat. It will be noted the opening in the drum at the lower end of pipe 32 is flared downwardly, this insuring that material will not clog or stick on itsl way to the said member. Also the beating and feeding apparatus mounted on the shaft 4 is not extended underneath the pipe 33 so that material is not thrown up into said pipe to clog the same.

Adjacent the opposite end of the apparatus, a discharge pipe 34 is provided at the lower side of the drum and a second discharge pipe 35 at the upperv side of said drumin which a dam er 36 or other control is mounted. The disc arge pipe 34 leads to a chamber 37 from which an outlet pipe 38 leads adjacent the upper portion of said chamber; and an inclined pipe 39 is mounted in the chamber with its lower end near the lower side of said chamber in which a suitable screw c onveyer 40 is mounted.

In operation, the material to be acted upon being introduced through the pipe 32 is acted upon by heat supplied through the pipe 33. At the same time the shaft 4' is rotated and the bars 29 strike and beat the material to maintain itin pulverized state, while the bars l1 continually scrape tlie'same from the inner "walls of member 1 and stir it in addition to the continual agitation of said material by the beater bars 29 and the curved eXtensions located at the left hand portion of the apparatus. This continual agitation and beating of the material with the application of heat vcauses a very rapid action of the heat thereon. The material before entrante .may be broken up and ground and the agitation and beating of the same while in the apparatus insures that it will remain in a finely divided or pulverized state, thereby giving the heat access to the particles for action thereon. A large quantity of the material can be treated in this manner where a much smaller quantity only could be successfully treated otherwise.

The products resulting pass through the discharge opening into the chamber 37; or in some instances part of the products pass out through the pipe 35. For instance, in the treatment of coal to secure the gaseous products thereof and coke all of the products are passed to the chamber 37, the gases being drawn out through the pipe 38 to any-desired place where the same may he condensed in combination with the usual methods employed in scrubbing the ley-product gas for light oil and ammonia. The solid products are conveyed from the chamber 37 through the agency of the conveyer 40 in the outlet pipe 39. Ordinarily the chamber 37 is merely insulated to prevent the escape of heat, but of course, if necessary it would be heated to keep any desired temperature. In the treatl ment of shale rock for the recovery of petroleum products the more volatile gases escape through the pipe 35, while the rock passes to the chamber 37 together with heavier gase coming from the distillation.

This apparatus is practical in every respect and has so proved in service. The passage of water through the shaft 4 together with insulation vof the shaft by the material 25 serve to keep down the temperatures of the shaft whereby bearing troubles in the head plates 3 and in the bearings at the upper ends of posts 5 are avoided. The beater bars 29 are shaped so as to give the greatest eiciencythough it is to be understood that the particular and specific shape may be varied without departing from the invention. Many other details of the structure and parts thereof may be modified in various ways without `departing from the invention and I accordingly do not wish to be limited other than as 4defined by the appended claims covering the invention. The specific disclosures made, while of a practical and operative device is to be considered rather as diagrammatic of the invention and not as limiting the same to any specific constructive details.
