HEATER OR COOKER FOR COTTON. AND OTHER OIIJ'SEED OR MATERIAL.

useful Improvements in .Heaters or Cookers for Cotton and other Oil Seed or Material, of which the iiollowing 1s a specification.

rlfhis invention relates to heaters or cookers, and more particularly to that class ot' such devices which are used for heating cotton and other seed and similar material preparatory to expressing the oil from the seed or material.

The primary object of the invention is to provide con'iparatively simple and effective means ior automatically controlling the heating or cookinfrot the material within the several receptacles comprised in the heater organization.

A further object ot the invention is to provide a heater ot' the class specified coinprising a series of cou'ipartments or receptacles with means cooperating.;` with each of the compartments or receptacles for automatically controlling the feeding of the 1naterial from one receptacle to another and thus enabling the feeding opei'ations and the removal ot' the material to be properly tin?. fl.

The invention consists in the construction and arrangement ot' parts which vwill be more fully hereinafter described and claimed.

In the drawings: Figure 1 is a section' taken transversely through one form of heater and showing the features of the invention applied thereto. Fig. 2 is a detail perspective view o'l`-tlie automatically op-y erating controlling` means for the compartments or receptacles and particularly embodying the features of the invention. v Fig. 3 is a. transverse vertical section on the line SW3, Fig. 2.

In the drawings the invention is illustrated as applied to a heater whichl in its reneral features ot construction is oit'. a

e common type. This heater comprises three con'ipartments orA receptacles 5, .6 and 7 which are arranged in super-posed relation, and it will.: be understood that the number of compartments or receptacles may be increased or decreased as desired. The lower receptacle 7 is mounted upon a suitable support, such as standards and all of the receptacles are` connectel in any suitable manA Specification of Letters Patent.

Application filed March 15, 1913. Serial No. 754,65S.

Patented ug. 29, 1916.

The bottoms 9 of the receptacles are tightly 60 associated with the side walls 10 byma chined `joints 10a consisting vof male andA female structures respectively formed in the said parts as shown. The receptacles are held separated or in spaced relation by rings tfL having flanges 8" .engaged by the cap screws n. yThe receptacles are also heated, by suitable means, live steam being pref` erably usedfor this purpose, and the bottom and side walls 9 and 10A of each compart-4 70 ment `or receptacle are formed hollow and suitably. Lcpnnected to a sour-cple of steam snplply and `have eihaust pipes,V not shown, `as in other devices ot this type, and by means of which a circulation of steam is main-- tained within the walls of the various com partnients or receptacles. It Will be understood tha*u the heat of the several compartments or receptacles may be readily regulated by the usual valves installed in the` pipes. The heating feature of the several compartments or receptacles does not form a part ot the present invention and therefore need not be further described in detail.

Arranged within each compartment or receptacle close to the bottom wall 9 thereof is a suitable stirrei' 11` preferably comprising one or more arms each supported yat the center of the compartment and having la rotary movement imparted thereto... A vertical shaft 12 extends through the center of each compartment or receptacle and has the stirrers secured thereon, the said shaft being rotated by a bevel gear 13 on the upper end thereof above the uppermost compartment orfreceptacle, this gear being rotated by a, bevel pinion 14 on a shaft 15 held in suitable bearing uprights 16 and carrying a belt pulleyor wheel 17 on its one end and to' which power may be applied from a suitable J3 source. The `stirrersL 11 operate to distribute the' seed or other material evenly over the bottoms of the respective compartments and stir the seed or material to cause the wholev mass to be evenly heated. Preferably the seed or material is first fled into the upper compartment or receptacle, then to the intermediate compartment or` receptacle, and

finally into the lower.compartment,or recep-`v tacle. The seed or material is heated ineach 119 compartment or receptacle and is Withdrawn from the lower compartment or receptacle. A feeding device or` apparatus 1s supported above the .uppermost compartment .opening 23 in the top plate 24 oi the uppermost compartment or receptacle. The opening 21 in the bottom of the box 20 is preferably of such dimensions as to permit the charge of seed or other material to pass from the said box into the chute 22 Without retardation but the feed will be under con trol by means which will be presently ei:-

plained. The bottom -9 of the uppermost' compartment or receptacle has an opening E25 extending therethrough adjacent to the side wall thereof andlocated over the next compartment below, the second comlpart ment in like .manner having a similar open.- ing Q5 in the bottom wall thereof. All of the` intermediate compartments or recepftacles will `he. provided with outlets in the bottoms thereof and Athe Alowermost intermediate compartment or receptacle will be arranged to discharge its contents into the top portion of the bottom compartment or receptacle of the group, the lowermost or bottom compartment being provided with a discharge opening controlled in a well known mannen` and need not be here shown. or described as the same Will be readily understood by those skilled in the art.

Means are provided for automatically controlling the discharge of the material from the box or compartment 2O to the uppermost compartment and from one compartment to another. The mechanism preferred and which has been particularly devised for this purpose comprises a plurality of rotary gates 26 which, as shown by Fig. 2, are in the form of disks each having an opening 27 therein adapted to register at intervals with the respective feed openings 21 a'nd 25. The rotary gates or vdisks are mounted on and secured to a Vertical shaft 28 disposed at one side of the heater and the uppermost gate or disk is disposed at vone side of the feed hopper 18 and extends between the bottom of the box 20 and the upper end of the chute 22 to control the opening 21. It will be understoodihat the openings 27 in the several rotary gates or disks are in diii'erent positions relatively to each other so as to accomplish the proper timed berging of the uppermost compara nient or i; izptacle' Ii and the feedingof the intermediate and bottom compartments or .-cszffihgtafcles 6 and 7. The ujiipermost rotaryl incase? gate or disk 26 will have its opening 27 coincide at intervals with the opening 2l inthe bottom of the box 20 and thereby permita charge to fall into the chute 22 and through the opening 23 into the upper compartment. or receptacle The size of the opening .37 ot the uppermost gate or disk and the speed at which the gate or disk rotates are so regulated that a fixed amount of material, preli-A their size by means of sliding gates 2l) arranged on opposite sides of the openings and having segmental slots therein engaged by clamping or set bolts, the slots being shown as at 30 and of proportions as to length wmmeneurate with the distances thereof from, the axes of the disks. The clamping bolts 31, as shown by Fig. 3, engage the webs of the disks, and the gates *2.9 have their inner and outeredges respectively seated in grooves 32 and bearing against overhanging flanges 33 at the peripheries of the disks. means of center Hangend hubs 34 and annuli 35 interposed betvs'een the `hubs and the webs 3 6 of the disks, there being one hub and a single annulus in each disk organization. It will be understoodthat all of the rotary disks are ofsimilar construction, the only variation being the differentiation of position of the openings E37 in the several disks so as to properly time the retention of the charges of material in the compartments or` receptacles for heating purposes and to reg ulate the feed from the hopper to the upper most compartment at regular intervals when the said uppermost-compartment shall rThe grooves 3:2 are formed by have been relieved of its successive charges.

The rotary disks cooperating with tl e bottom openings 25 of the compartme ex# tend inwardly into the top portions oil"`the compartments which they engage through openings 37 provided for this purpose, the rotary disks closely engaging the lower portions of said openings 25 so as to insure against leakage of material in the several compartments `and permit a discharge of the material from one compartment to another only when the openings 27 Aof the disks coincide Aor register with the openings 25.

The shaft 28 is mounted insutable bearings 38and 39, the bearing 39 being `ci@ the` foot or step type and held by a, suitable supporting bed 4,lo extending outwardly in] line with the bottom ol the lower;comparis` ment or receptacle and. having a prop or ien;

leo

' 'this operation be desired. This is -accomi shown. i lowerportion of an auxiliary frame 48, and

in the upper part ofsaid frame a power transmitting shaft 49 is disposed in suitable band' pulley to receive power from any Variable speed mechanism 20.

" lished through the medium of` a friction or A]av'v clutch 45 associated in part with a shaft 44 and in partwith a countershaft 4G, the

'lclutch'being controlled through the medium of a hand-lever attachment 47, as clearly The shaft 46 is mounted in the bearings and provided with a belt wheel or suitable source. is provided in connection with the shafts 46 and 49 and in the presenetv instance consists of stepped .pulleys 51' and 52 on the respective shafts 46 ande49, the said pulleys being engage-d by a belt 53 which may be shifted as desired to modify the speed of the shafts 44 and 2,8 and` thus'regulate the speed of rotation of the rotary gatesor disks 26 when the clutch. is operated to connect the two shafts 44 and 46.

i The operation of the improved heater will be readily understood from the foregoing description, and vit will lie apparent that -fixed quantitiesvof material are fed into the upper compartment4 or receptacle at regular intervals and in sequence similaiquan tities of material are fed from the coml'-partment 5 intov the compartment 6 and from the latter Vinto the compartment 7. The material as fed into the several compartments isv evenly vdistributed over the bottomewalls 9 by the stirrers 11 and is heated to the degree desired or inaccordance with the adjustment. of the gatas or slides 29 relatively tothe openings 27 of the rotary disks and the speed of rotation imparted to the 'said disks. Whenl the several charges of material shall have reached the loWer compartment or receptacle theywill be removed at fixed intervals and in any desired uantities. By means of the organization o devices hereinbefore described, all ofthe material fed into the upper compartment and passing onto the succeeding compartments must remain a fixed time in each several compartments as the heat can be more gradually applied to the seed or meats and evenly distributed with respect to all portions ofthe'seed or meats. Frequently Where large quantities of the product to be treated are cooked it is found that portions of these large quantities of material when removed from the heater are not suiiiciently cooked. Furthermore, by meansI of the improved heater, neglect or inattention on the part of careless employees does not result in injury to the material treated or heated, as the heater will automatically work or discharge the quantities of the material regularly from one compartment into another and the feed will be maintained at intervals iii the uppermost or first compartment,

.and it is therefore practically impossible to overcook the material in the several compartments. A still further advantage in the present improved heater is the automatic charging Yof the upper compartment by the mechanism heretofore explained and independent of any manual operation or depend ence.A

It will be understood also vthat the cooker will be equipped with such devices as are usually employed in connection with the several compartments for observing the interior operation of the latter and readily understood in the art. v
