through any suitable means, as by a lever 5, for changing the speed from low to high, and to medium. By the placing of the lever 5 into the position as illustrated at L, a low speed would be obtained. Whereas by placing the lever in position as illustrated in full line view in Fig. 4,

and in registerable alignment with the letter M,

a medium speed would result whereas by the placing of the lever indicated in position H, a high speed would be produced. I do not lay any particular claim to the speed reducing or speed changing mechanism as there are many devices that may be used to produce the desired result.

Shafts 6 and 7 are disposed transversely of the frame and are journaled within suitable bearings 8, 9, 10 and 11 that are disposedupon. the frame. The shafts are driven by any suitable driving mechanism as by a sprocket 12 that is placed upon a shaft extending outward from and being disposed through the gear box 4. The sprocket has a chain 13 trained thereabout that acts as a driving chain. A second sprocket 14 is disposed upon the shaft 6 and a chain 15 coacts therewith that passes about the sprocket 16 disposed upon the shaft 7 and thereby drives the supporting wheels 17 and 18 mounted upon the shafts and upon which the barrel, cask, or other object to be painted, rests. The rotating of the supporting wheels causes the object, to be painted, to be rotated. I have found best results are obtained wherein the supporting mechanism for the object to be painted is toothed upon its outer periphery to thereby cause the object to be painted to rotate as the supporting wheels, or

toothed members are rotated.

Vats 19 and 20 are disposed at the oppositely disposed sides of the frame into which the'coat ing material is placed. A third shaft 21 is disposed transversely of the frame and is journaled .within suitable bearings disposed within the frame members. Agitating heads 22 and 23 are disposed upon the oppositely disposed ends of the shaft 21 and as the shaft 21 is rotated the agitating heads are rocked.

A pitman 24 is mounted ,upon the shaft of the gear box and a pitman rod 25 is secured to the pitman 24 upon its one end. The pitman rod is secured upon its oppositely disposed end to a crank 26. and as a rotating motion is imparted to the pitman 24 a rocking motion will be imparted to the crank 26 to thereby rock the shaft 21 and to impart a pendulum action to the agitating heads 22 and 23 to maintain the coating material in a uniform state of viscosity within the respective vats 19 and 20. 1

A vat 27 is disposed at one end of the frame and a shaft 28 is disposed within the vat upon which an agitating head 29 is disposed. The shaft 28 is rocked through a pitman rod 30 connecting the crank 31 disposed upon the shaft28 and the crank 32 disposed upon the shaft 21. Power driven pumps 33 and 34 are mounted within the frame and are adapted for being" upon one side of the spray head 38 and the spray head 38 is shaped to fit the contour of the object to be painted in order that each of the spray nozzles may be substantially thesame distance from the object to be painted.

A brush 40 maybe made to engage the outerperipheral surface of the object being painted are inwardly disposed from each of the heads 1 ture and power transmission means operatively to remove the surplus material therefrom, the same being so placed so as to drain the surplus material back into the respective vats. The pump 34 is secured to the base of one of the paint vats by a pipe 41 and a discharge pipe 42 is secured to the discharge side of the pump 34.

Spray heads 43 and 44 are disposed at the oppositely disposed ends of the objects to be painted andthe same are connected by suitable piping connections .42, with the pump 34. In order to adapt the spray heads 38,. 43 and 44 to the various sizes of articles to be coated, suitable arrangements may be made to adjust the spray heads to the article to be coated. Spray nozzles 43 and 44 and are properly spaced to completely coat the head, or end, of the article to be painted. In view of the fact that coating materials of different colors may be applied to the heads and to the outer peripheral surface of the object, protecting shields 46 and 47 are supported upon the frame and are made to come in close proximity to the head to prevent the deposit of the different colors being applied to the heads and the body of the object to be painted.

Entrance rollway tracks 48 are disposed upon one end of the frame over which the article to be coated may be rolled and discharge tracks 49 are disposed upon the opposite end of the frame over which the article may be rolled after the coating has been completed.

When it is found desirable to coat the surface of the object to be coated by hand, the discharge spray heads 43 and 44 and the shields 46 and 47- may be removed and the spray head 38 may be also removed,- at which time the coating may be carried on as a hand operation. a v

While the form of mechanism herein shown and described is admirably adapted to fulfil the objects primarily stated, it is to be understood 11 that it is not intended to confine the invention to the. one form of embodiment herein shown and described, as it is susceptible of embodiment in :various forms, all coming within the scope of the claims which follow.

What I claim is:

In a devicefof the class described, the combination of an elongated and elevated frame, a paint holding vat extending transversely-of the frame at one of its ends, a bail member rotatably mounted in said vat and adapted to agitate the contents thereof, similar vats arranged on both. sidesof the frame near the end carrying the said first mentioned vat, apair of parallel shafts rotatably mounted transversely of the frame, a plurality of toothed wheels fixedly secured tov and rotatable with said shafts and adapted to rotatably support an article to be painted, a prime mover mount'ed within the frame strucinterconnecting" the prime mover with said rotatable shafts, conduits extending from said vats through power driven pumps thence upwardly to points-above the frame, saidconduits beingprovided with spray nozzles, twoof said conduits, terminating in endless circles arranged one within the, otherat opposite sides of the frame and each of said circles being provided with spray nozzles, the other of said conduit terminating in a laterally disposed conduit extending transversely of the frame, all of said conduits adapted to convey paint under pressure'to and through the nozzlesto the articles to be painted.
