useful Improvements in Steam-Cookers, of

which the'following is a specification.

My invention relates to steam cookers, or apparatus used for the preparation and treatment of large quantities Of cotton seed, fish, or similar materials, to be subsequently operated upon in oil presses.

The objects of my invention are, rst, to so construct andl arrange the parts that the steam or cooking medlum can be so regulated, that the temperature and steam can be cont-rolled and modified at any one of the different sections of the cooker independent Of the other sections, and Without it being necessary to stop the apparatus or effect the feeding ofthe material into the apparatus, or its discharge therefrom. Second, to provide means whereby" the Operation can be made a continuous one and the material fed through the cooker uninterrupted and of varying speeds if so desired.` Third,

to so arrange the parts of the cooker so that access may ibe readily had to any of the parts in order to quickly examine the same and make necessary adjustments, or repairs, or replace broken parts in the least/time and at a minimum cost.

Further objects and advantages will ap-l pear from the detailed description hereinafter referred to.

The invention consists of structural features and relative arrangement ofthe different parts comprising the inv` ntion which will be hereinafter more fully described and particularly pointed out in the appended claims.

In the drawings in which similar reference characters indicate the same parts in the several figures of drawings.: Figure 1 is a side view of the cooker, partly in longitudinal section to show the interior construction Of the barrel; Fig. 2is a plan view, partly in section to show the interior of the barrel; Fig.v 3 is an enlarged sectional view of the cooker at the outlet end of the barrel; Fig. 4 is a section on line 4-4 of Figs. 1 and 3; Fig. k5 is a section on line 5-5 of Figs. 1 and 3;,and Fig. 6 is an enlarged fragmentary section of a coupling or diaphragm of the inner steam spray pipe'fshaft.

In the drawings, l, 1, are structural steel pedestals or base sections and braces, Which rigidly support and firmly hold the imperforate, container barrel 2, .having the inlet -head 3, and outlet or discharge head 4; said barrel 2,. being provided With the feed neck for the attachment of inlet chute 5 for feeding Iof the material, and manholes and co-vers 6, for access to the interior of the barrel to permit examination, adjustment and repair of all parts vWithin the same.

7 is a discharge opening in the lower side of head 4, having a pivO-ted door plate 8 for varying the size of discharge opening 7.

Base pieces 9 are provided with cross pieces 10 and braces 11, for rigidly supporting the journalboxes 12 carrying the shaft 13, of the driving gear, to be presently described. Fastened to said shaft 13 is a clutch' 21', controlled by a lever 22, saidv wheels 19 and 20 being geared to Wheels 14 =and 15, by

25 represents' a perforated, rotatable steam 'spray' pipe shaft Within the barrel 2, v,preferablyv at the out-let end and which `passes at one of its ends through a suite .able opening and packing inthe discharge head 4, While its other or inner end rests in.

diaphragm 28 which is rotatably supported in a bearing 26, fixed to the inside of the barrel, as shown in Figs. 2 and 5.

27 y's a 'section of a perforated steam spray pipe shaft forminga continuation of the section 25, and separated therefrom by .adiaphragm 28, and 29 is a similar section extending from the end of section 27 and separated therefrom by the diaphragm 30. Said section 29 passes through an opening, provided with steam tight packing, in the inlet head 3, and is provided on its outer end with a solid removable cap 31. Each of said sections 25, 27 and 29, are provided with suitable perforations 32 for the purpose of permitting steam or other heating or cooking medium to pass from the interior speed, and a means of Well known sprocket . chains 23 and 24, as shown. f

of said sections into the interior of the barrel 2, and each of said diaphragm sections 28, and 30, rest in bearings 2G, thereby rotatahly supporting the full length or sections of spray lpipe shafts 25, 27 and 29, properly and equidistant fromthe inner wall of the barrel.

32, 32', are combined miXers and conveyer paddles arranged radially and secured to the different sections of the rotary spray piper shafts 25, 27 and 29, and rotate with the same, for the purpose of not only thoroughly mixing and agitating the material fed into the barrel 2, by the feed chute 5, but also convey the said material through the barrel from right to left, and finally out through the discharge opening 7, to be received in any suitable conveyer, through 33.

34 is a stationary steam distribution cylinder, rigidly held and supported by means of a standard 35 secured to the base pieces 9, and is closed at its outer end by a removable cap 34', and open at its inner end to snugly receive the outer and imperforate end of the rotatable spray pipe section 25, which passes through `a suitable opening and packing in the discharge head 4, as shown in Fig. 3. Surrounding and secured to the outer end of section 25 and interposed between the drive gear 17, and head 4, and abutting against said head, is a thrust collar 36.

37 is a central imperforate rotary steam pipe, leading from the interior of section 29, through the diaphragms 30 and 28, sections 27 and 25, and head 4, to the interior of the forward end of the steam distribution cylinder 34, and passing through and connected to a piston 38, revolving in said cylinder 34. Connected at one of its ends to the diaphragm 28, and situated within the spray pipe shaft 25 and surrounding the pipe 37 and separated therefrom is a second rotary steam feed pipe 39,. which also passes through the head 4 and into the cylinder 34,

and is also connected to a rotary piston 40, in the same manner as pipe 37, and as shown in Fig. 3.

The rotatable, perforated spraying pipe shaft 25is extended through the head 4 and thrust collar 3G, by an imperforate section. whose outer end surrounds the pipe 39 and also is separated therefrom, and is rotatably supported in theopen end of the cylinder :34 which is provided with a gland 41 to insure a tight joint between the said shaft 25 and `cylinder 34.

42 is a main steam supply pipe which in the present invention is provided with three branches 43, 43 and 43, each having its own controlling valve 44, 44' and 44, respectively, and lead into the cylinder 34 on different sides of the pistons 38 and 40, as shown, so that pipe 43 communicates with the interior of pipe 37, pipe 43 with 39, and pipe 43 with spray pipe shaft 25t 45, 45 and 45 are drip pipes connected with the bottom of the cylinder 34 on different sides vof the pistons 38 and 4() and are controlled by suitable valves, and lead to a common drain pipe 4G, for the purpose of withdrawing any water accumulated in the cylinder34,due to condensation of the steam.

47 represents a lagging which may be placed on the outside of the barrel 2 for the purpose of insulation, and for retaining the heat within the barrel.

lf it is desired, the pitch of the paddles 32 may vary from the inlet end toward the outlet, and preferably are so arranged that the paddles attached to section 29 will cause the material to travel faster than the paddles of section 27, and paddles of section 25 advance the material slower than the paddles attached to section 27.

While I have shown and described three spraying or heating sections, 25, 27 and 29, l do not care to limit myself to this exact number, as this number could be varied more or less, without departing from the essential features of my invention. Furthermore, while l have Shown the conveyer paddles attached to the rotary spray pipe sections, this is not essential for carrying out the invention, as the conveyer fiights may be attached to the barrel which can be rotated, and the pipe section so as to be stationary, as will be readily understood by one skilled -in the art, but I have herein illustrated my preferred form.

The operation of the apparatus is as followsz-They uncooked material is fed at a uniform rate into the chute 5, and the clutch 2l is thrown so as to engage either of the sprocket wheels 19 and 20, depending on what speed it is desired to rotate, by means of intermediate shaft 12 and gears 16 and 17, the inner spray pipe sections 25, 27 and 29, with their attached conveyer paddles 32.- The live steam is admitted into the different sections 25, 27 and 29 by openingV the valves 43, 43 and 43, and the amount of steam issuing through the openings 32 of each of said sections into the barrel 2, is separably and independently controlled, depending upon what valve is operated. The material within the barrel is agitated by said paddles 32 and conveyed through differentzones of heat and steam density, moving along the section 29 at a certain speed, then slower at section'27, and slowest at 25. Thel maximum of cooking is effected at section 29, owing to great capacity or volume of steam in said section 29 as compared with that of section 25, and by opening thevalve 43a greater quantity of steam can be admitted in said section 29. The spray section 25, by properv adjustment of valve 43 can control the steam to such an extent as to cause a portion of pipe section 25 to act as a hot baking pipe beforeV the material is finally l'll discharged out of the opening 7 into the conveyer 33. In order to 'control the steam pressure and spraying in the section 27 one adjusts .the valve 43. From this method of operation it will be seen that by means of said valves 43, 43. and 43, the quantity or pressure of steam in sections 25, 27 and 29, can be simultaneously or independently controlled of each other, and Without interfer-ing `with the operationof the machine,

and so regulate and absolutely control the cooker too rapidly, the clutchl 21 can be thrown from engagement with the sprocket Wheel 20, to the Wheel 19, and if a higher speed is desired, the clutch 21 is moved from the wheel 19 to engage 20, thus a further condition of regulation of the material is had in addition to the control of temperatures and steam supply, as above explained.

From the `foregoin disclosure of construction and lmode o operation of the invention, it Will be seen that the apparat-us is capable of cooking material of variable quality continuously and progressively, with an economical use o f the steam, and at vthe same time produce a better and uniform product in one apparatus in continuous operation; and all regulations of the operations being accomplished Without interruptions .to the apparatus. the steam distributing pipe 37 within the sections 25, and 27, and pipe 39 within section 25 and the pipe 37, and said pipes 37 and 39 leading to fa common distribution cylinder 34,. this' enables the valves 44, 44 and 44, respectively contro-lling the steam of the sections 29, 27 and 25, to be placed in such proximity to each other at the dischargel end of the cooker, as to be quickly and read.- ily controlled at one point of the cooker by a single person, Without being required to move from his position at 'the discharge end, while observing the vmaterial passing out of the opening 7, and in this respect differs and has great advantages over priorcookers, in which the pipe sections and steam connections are so arranged that a person is required to travel from one place toanother, up and down the full length of the cooker, in order to cont-rol the different sections.
