HEATER CONTROL MECHANISM.

To all whom it may concern. p I

' Be it known that I, ALLEN BRAN'rI vGQ HAM, a citizen of the United States, residing at Toledo, Lucas county, Ghio, have relates to a treating device Referring to the drawings: F igure 1 is a side elevation with parts broken away of an embodiment of the invention in a'grain heater; Fig. 2 1s a fragmentary elevat on of features of the automatic controlling mechanism as seen from the left of Fig. 1; Fig. 3 is a fragmentary plan view of the device of Fig. 1; Fig.4 is a fragmentary section on the line IVIV Fig. 1, looking 1n the direction of the arrow; Fig. 5 is a section on the line VV F ig. 2, looking in the direction of the arrow, showing the parts in trip or dump position; Fig. 6is a View on the line VIVI Fig. 2, looking m'the direction of the arro-w, with-the parts advjusted for minimum throw in driving as controlled by the material receiving hopper; Fig. 7 is a fragmentary section of one of the heater ways showing a type of baflie therefor; Fig. 8 is a plan view of the way and baffle of F ig. 7 Fig. 9 is a fragmentary section of a way showing a link type of battle; and Fig. 10 is a transverse section through such way and baffie.

The jacketed treating device or heater 1 comprises the drum section 2 having dia phragms 3, 1, therein connected by the ways or tubes 5. The space between the ways 5, the diaphragms 3, f and the drum 2 forms a chamber for a heating medium as steam so that the travel of material through the ways 5 may result in a treatment of such material in bringing the material to a dey sired temperature or for drying .such material.

tion with the ways5. This; hopper .7 is provided with arm 9 yieldably poised 'by the spring 10 guided on the bolt '11 to thereby Patented Nov. 30, 191 5.

yieldably maintain the hopper 7311 such,

adjusted position as may be determined by the setting of nutson the bolt 11.

The material received in the hopper passing through the openings 8 and into the ways/5 is delivered from the Ways 5 to the openings 12in line with the fixed chutes or hoppers 13 having compartments 14 reg 1 is'tering with each of'the vwaysf). These compartments are grouped'in series for,

platform nember 16. Below thesereceiving discharging over the slats 15 forming a. slotted platform-carried by the receiving slats 1 5 is the outlet hopper 17into which 7.

the material passing between the slats '15 is discharged. The receiving platform member 16 is provided withtra'ck extensions 18 coacting with rollers 19 carried by brackets 20niounted on the heater 1, 'so that this glatform member is free for reciprocation to move the slatsv 15' laterally of the'series of hoppers 13 to permit spill from said hoppers 13 through the slots between the slats 15 either by direct flow" or in its reciprocation to crowd the material off the slats 15. -This reciprocable platformzmem ber 16 has the extension or bracket 21 carrying the pin 22 passing through the A slot23 .of theyoke 2 1 engaged by the rod 25 extending to the upper hopper arm 9. as to which it is held in adjusted relation by the nuts 26. Accordingly as material accumulates in the'hopper 7 to overcomethe re-.

sistance of the spring 10, the rod 25 may settle down to bring, the pin 22 into 'engag ing relation with each of the sides of the A-slot 23, while as the loadbecomes lighter in thefhopper 7, the spring lOmay force the I rod 25 upward so" that the pin 22 may have considerable play, as between the sides of the A-slot 23. This A slot member 23 is engaged by the link 27 mounted on the crank 28 of the shaft 29 swung by bearing brackets 30 fromfthe shaft 31, which shaft 31; is

mountedfo n the heater 1 by the brackets32.

The shaft 31 maybe driven continuously by the belt pulley 33, and through thesprocket r 3 1onthe shaft 31 drivethe sprocket chain Mountedupon the upper portion ofthe 35 passing about the sprocket wheel 36 on platfornr memberf15, 16.: The extent lof- 'thesereclprocation's is automatically varied by the positionof the A slot' member 23' as controlled by the material supplied in the hopper 7 Fast to the shaftBl isthe bevel gear 36 in mesh with bevel gear 37 ontheupright shaft'38, which carries the 'flyball governor 39 having the collar 40 engaging the link, 41 of the toggle links 42, 43, between the fixed bracket 44 on the heater 1 and the swinging brackets carrying'the shaft 29. With the shaft 31 driven at normal speed, this speed regulated device or fly ball governor 39 will, throughfits ,collar 40, hold toggle 42, 43, in such position that the link 27 may drive the platform slats 15 back and forth under the series of hoppers 13, as controlled by the basket; 7. However, should the mill be shut down or the drive cease for any cause, the speed controlling device or,

' governor 39 will act as an 'automatic dump and immediately break the toggle 42, 43

' (Fig. 5) and thereby swing the brackets 30 and the shaft 29 toward theh'eater 1 to force the slats 15' into such position that, there may be material flow from the heater 1. Thisis an automatic emergency control espe- .cially desirable, as in'usual stream control of material in mills there is a drive for the ele-' vator, and if the shaft 31 is driven in connection with the general 'run ofinachinery in the mill,-stopping of the elevator would of course. stop the material supply to the heater and should the simultaneous stop- 43 to bring the slats'15 into material hold ing position. 7 p

The ways 5 are provided with baiiles or means for effecting a rolling or agitation of the grain to better insure uniformheating in the intermittent travel of the grain through the ways' The cross bar 45 over the ways 5'may carry flexible wire cable 46 having strung thereon the platform providing elements or' glass beads 47 positively held in alined relation and centrally of' the ways 5'by series of three armed centering means 48 strung on the cable 46 between the platform elements or beads47. By making the platforms 47 of glass there is acheap wear resisting material. In providing the stem 46 of flexible material the beads may be strung thereon and the bafiie readily re 'moved from the heater or placed in posi-' tion therein even though the heater may be placedclose to overhead structures, as ceil- 7 ing or roof: This is a point of material advantage inpermitting the desired of the device in many millsyl 7 Instead of the continuous cable 46 in a built up bafiie, there may be provided a seriesof U-shaped links or members, the U- shapedmember 49 being provided with centering extension means or arms 50. This link 49 may be assembled through the crossshaped openin'g'51 within the platform or disk 52, while the link 53 may be staggered or, oppositely assembled therethrough by springing in the'shorter arms 54 which may seat upon the opposite side of the disk 52 from the arms 50. These links assembled the platforms 52 may be in staggered relation to form a flexible continuous baffle, which baf- He is flexible for insertion into the way 5 placing and removable therefrom but is positively held centered therein by thestaggered series of-arms 5Owh1ch vhave such relation as to the disks 52 as to firmly engage the ways The 'material flow in its intermittent travel through the ways 5 lands upon the platforms or disks 5:2, is rolled thereover to present difi'erent materialto the walls of the ways 5 and thus insure a-uniform heating of the grain in its passage through the heater; i V

In the device of the disclosure there is device having heater control mechanisms caring for such stream of material as the demands of the mill may present for uniform heating up to the capacity of the treating device. The extent of the heating may be varied by controlling the steam supply through the valve 55 and the condensation passing from the valve 56. The variations in material supply at once effect the flow rate through the heater through the automatic adjustment of the reciprocation of the platform slats 15 as controlled by theA-slot member 23, the loading down with material increasing'the flow and accordingly increasing the flow rate. In addition to this automatically adjustable flow connection there is the self dumping scheme as controlled by the governor 3,9 precluding retention of the material in the hopper for overloading or burning in the event of shutting down of any of the driving devices in the mill.
