Dieren-Counting non Winningen y 4To.cllfwh'om 'itmy concern; v' i Y Be it know-n that l, MICHAEL 'CincinnatLin the .'county of Hamilton and -State of 0hio,have invented certain new and f, useful Improvements inDrier-Conveyers for White Lead, of which the following is a speci- ,iicati'on; y y

t It is the objectof my invention to provide a drier conyey'er for white. lead..

-In the manufacture of white lead it is the acetic acid, or '-ot er chemicals/in suitable pots, which etrel stacked in layers one` abovev the other withboaids and tan-bark between the layers, Iafter which the decomposed lead .is ground by vsuiteible mills and passed through a. separator. The white lead so sepI arated is Athen ground in water,` the ground .rwhite'llead-.fpbeing then vpermitted to piecipi` tetex The lpractice heretofore has beenand still is to dry this precipitated whitelead in' large pans, a tedious and? time-consuming method.

l.it is thtbbject'of mymventifm t6 dispense with the drying of this white lead in pans and to .provide a driei*`-co`nve ;'yery of' novel coni struction especially applicablefor this jpurf of Fig. 3

pose, andthe inventioniwill be readily understood 'from the following description and claims,` and from the l drawings, which latter: y y I l Figure 1 is a central v y i y. longitudinalvertical sectionl of my improved device onfthe line the same on aline corresponding to the line y'-y of Fig. 1 g end,r Fig. 3 is an `end velevation ofthesarne..`

3 is the end-wall of ythe trou-h iat the feeding-in end thereof and 4 is the end-wallof A the trough at thefeeding-out end thereof.

These respective end-.walls have slanting sides at their upper ends as shown at 5 which z I act as rests for top-plates or' lids 6. The end-wall 3 has a flan 4e 7 which extends ini hwardly of the trough, in which there is an inlet-openingr S for the trough, an inlet-pipe 9 v communicating with they` opening 8.

1() is an outlet-openinginthe bottom of the trough at its outlet-end, with which an-outlet-pipe 11 communicates;

The outer parts of the heating' pipes `are preferably embedded in 'a body of cemen-tl'S supported in a case 19,

the inner fa e of the eemenbbed being l. referably offa orm similar to the shape. o the series of p'ping. escapei-ii 'e 17 for condensed steam 'ina be prov The inlet-'end oft ie white-lead' trough is i preferably v`lower than the outlet-end of the trough so thatl the moisture vin the saturated White lead will have aytendency to remitin or v be directed. toward .the inlet-end of the trough and thereby aid in the drying action asthe white lead is forced tow-ar the outlet opening of the trough by. the conve ermechyanism presently to be described. I he piping and innerv face of the cement-bed `are also preferably inclined 'longitudinally similarly to` the incline' of thewhite-lead .trpugh, and the case 'maybe given a similar inclination by mounting the same on blocks 20, but I do not limitinyself `'to inclir'iing Lthese iirts as stated. The rounded 'bottom of t e' Whitefield trough `is preferably voi cop r or such ma terial 'as ynot to be jchelniea y detrimentally affected by the whitelead and protects thev ipes and cementfro'in lcor-itact bythe whites` eed to prevent'disintegration of the Cement,

' which may 'be a usual mixture of hydraulic -cement,sand and. water; The'upperends of this `rounded bottomea're bentsidewardlyo'yer the body of cement and secured in suitsble .manner to thecase. The iidsorto lates '6 may have la lining 22 of copper. ey are shown hinged by hinges 23 to strips- 24 extending longitudinallyof 'the trough at the respective sides thereof and secured to the cese lin suitable manner as by the bolts 25. The `lids may be swung back on their hinges for inspection of the contents of the trough.A They prevent spattering oi the white lead beyond the sides of the trough adjacent they top of the trough. 'Their upper ends are 55 ably steam-pipes, fed, for iiistancex by a. I preferably separated however forforinng an opening 2G extending longitudinally,ofthe trough. This opening is provided for perniitting eso-ape of steam aiidffiinis'fiioiii'the trough. At intervals the upper edges ofy the 5 lids are' providediwitli separating' 'blocks'.4 27
