May 26, 1931. A. L. CULBERTSON WATER COOLED AGITATOR Filed July 27, 1926 WM ,2. v

ATTORN EYS I INVENTOR '10 fluid through the main tube and its several parts employed may be readily removed for Patented May 26, 1931 I UNITED STATES- PATENT; omen ALBERT It. GULBERTSQN, OF MOUNT VERNON, OHIO; ASSIGNOR\, BY MESNE ASSIGN MENTs. TO, THE TION or OHIO Application filed J'u1y127,

. The invention relates to the watercooling oli tubular members, such as. the a itator arms; employed for conditioning the ire'bed of a g s p oducer, having-'fingersor o her imil branch members extending h re r h also should be subjected to theaction of the co0Iing-fluid.- I

The primary object of the invention is to provide for the circulation of the cooling fingers or branch members in such manner as to insure that all the above parts will be uniformly and adequately cooled. Another object of the invention is to provide a construction of the'above nature in which the various replacement or repair.

Further objects and advantages of the invention will be in part obvious and in part specifically pointed out in the description hereinafter contained which, taken in conjunction with the accompanying drawings, discloses a preferred embodiment thereof. Such embodiment, however, is. to be considered as merely illustrative, of its principles. In the drawings- Fig. 1 is a side elevation partly in section of an agitator constructed inaccordance with the invention. 7 V

Fig. 2 is an end elevation of the structure shown in Fig. 1. l 7

Fig. 3 is an enlarged longitudinal section of one end of the agitator shown in Fig.1.

Fig. 4 is an enlarged side view partly in section of a fitting adapted to be employed in carrying out the invention;

Fig. 5 is an end elevation of the structure shown in Fig. 4.

The invention is illustrated. as applied to an agitating member having a'vertical stem 1 providedwith a tee coupling 2 at its bottom end to which coupling the horizontal agitator arms 3 are attached. In use such an agitator is turned around slowly in the surface of a gas producer fire bed or the like, and the arms 3 are provided with fingers 4, which project down into the fire bed and serve to condition the latter more thoroughly. Cooling water for the agitator is supplied through a pipe 5 in the stem 1 which leads to pipes 6 WATER-casino AGITATOB,

within the horizontal arms 8, the cooling water usually-returning. through the annular space -7 between thestem 1 and pipe 5, afte1; passing through; the agitator arms and fingers. V r v 1 Inaccordance with the present-invention the cooling fluid is caused to pass in series? or successively through the various fingers or branchv members. 4:; which are. associated withthe respective agitator arms,- theeools ing water first passing-through'pipes 5 and 6 to. the outerend of each agitator arm and, then being guided-by suitablefittings to pass successively through the fingersorgbranoh members in its return travel-from the outer ends of the agitator arms to theannular space 7v n s m 1. Of. co r he: ame u u e would permit. a reversal of the direction. OLE flow of the cooling fluid throughthe -agita-. tor-,jif desired, whereby the cooling water would flow in throughthe annular space 7 and out through pipe 5.. I y a P j H In he i lus r t e mb diment o he vention each branch 1 memberor finger 4 has associated: t erewi ha fi ting pr vide with a head 8 which surrQ-llnds the. corresponding pipe. 6 nd. obst cts t longit inalflqw, Qt Water thr ugh the ann la asp ce 9. between th eeitatpr' rm pieefi-s Ea h fitting furthermore is provided with a stem; lQ which 7 projects down into the interior ofthe corresponding finger a d ha a pas age ay T communicating between the interior of the finger ii; and the face ofhead 8....Thus with regard to. the arm 3, shown at the-righthand side of Figure 1, for example, the cooling fluid may flow from pipe 5. through pipe 6 Pipe 5..-

A path of travel of the above nature for the cooling water insures that each finger 4 will be adequately served with cooling water, since all the water passing through each arm 3 must pass through each finger which is associated therewith. If the cooling water were passed in parallel through the several fingers 4, the flow through any particular finger could be partially or entirely clogged without affecting the flow of cooling water as a whole, and thus the finger would be more likely to become over-heated without any indication to the operator that the supply of cooling water was inadequate.

Stems 10 preferably are restricted at their ends, as shown, to cause a greater velocity in the water issuing from them, thus more effectively carrying away deposits which tend to accumulate in the ends of the fingers.

As above stated, the invention also preferably includes certain features facilitating the assembly, replacement or repair of the parts of the agitator. As shown, each fitting is slidable along its corresponding pipe 6, and the several fingers 4 are screwed into bosses 12 on the arms 3. In assembling the parts the heads of the fittings may be passed through the holes in bosses 12 and strung along the corresponding pipe 6 as the. arm 3 is pushed inwardly along the pipe, the arm 3 being finally secured to the tee coupling 2. The fingers 4: are then screwed in place in bosses 12. The stems 10 of the fittings pref erably are provided with lugs 15 to space them properly from the walls of the fingers. The fingers 4: of course may be unscrewed at an time for repairs and replacements.

ile a specific embodiment of the invention has been disclosed it will be obvious that many changes may be made therein without departing from itsprinciples, as defined in the appended claims. The principles of the invention of course are also applicable to hollow members carrying heating instead of cooling fluids. Y

I claim:

1. In combination, a hollow firebed agitator member to be fluid cooled having hollow fingers spaced along the same, a fluid-conducting tube within said first-mentioned member, and fittings respectively coacting with said fingers, said fittings having heads disposed within the hollow member and enclosing the tube at points respectively adjacent the fingers, and also having passages extending through said heads to the interiors of the corresponding fingers.

2. A water cooled firebed agitator mem: ber comprising an upwardly extending stem, laterally directed arms extending therefrom, said stem having a cooling water pipe passing therethrough and said arms having water conducting tubes therewithin which are connected to said pipe, said arms also having hollow fingers projecting therefrom at points spaced along their lengths, and means for directing serially through the fingers carried by each of said arms, the water which flows through the corresponding tube.

3. A firebed agitator for gas producers and the like having a hollow arm, hollow fingers projecting from said arm at points spaced along its length, said fingers being detachably connected to said arm, a cooling water pipe enclosed by said arm, fittings having heads enclosing said pipe within said arm to obstruct the flow of cooling water along the arm, said fittings having stems respectlvely projecting into said fittings, and said fittings being provided with passageways leading from their heads through the stems to the interior of the fingers, to direct cooling water serially through the fingers.

In testimony that I claim the foregoing, I have hereunto set my hand this 13th day of July, 1926.

ALBERT L. CULBERTSON.
