Specification of Letters Patent.

Patented Apr. 22, 1919..

Application filed February 27, 1919. Serial No. 279,505.

To all whom it may concern:

Be it known that I, J OHN P. ODoNNnLL, a citizen of the United States, and resident of the city of Providence, in the county of Providence and State of Rhode Island, have invented certain new and useful Improvements in Galvanizing Apparatus, of which the following is a specification.

This invention relates to an apparatus for. applying a protecting coating to metal articles such as buckets or the like, and has for its object to provide such an apparatus that is simple and inexpensive in construction and effective in its operation and that is adapted to engage and immerse articles such as metal pails into a bath of galvanizing or other similar molten material so as to coat the articles both on the inside and outside evenly and uniformly and to carry the articles through the bath without permitting them to contact with any adjacent objects.

With these and other objects in view, the invention consists of certain novel features of'construction, as will be more fully described, and particularly pointed out in the appended claims.

In the accompanying drawings:

Figure 1 is a sectional side elevation of my improved apparatus.

Fig. 2- is a plan view of the same.

Referring to the drawings, 10 designates the tank in which a bath of molten metal may be carried, the same being of suitable width and length to contain the desired quantity of coating material to permit the work to be immersed therein.

The drum or cylinder 11 performs the function of a carrier and is provided with a central shaft 12 extending out from either end thereof to run in bearings 18 mounted upon the tank. This drum or cylinder is of a length to extend transversely across the tank and is of a suitable shape to provide a dam or barrier for retaining the flux indicated at 1 1, at the entering end of the bath, which flux is of a gravity less than that of the molten metal 15 in the tank and floats thereon. On this carrier I have mounted a plurality of grippers or engaging members 16 arranged around its circumference, which members are provided with a pair of jaws 17 one of which is pivoted and normally pressed against the other by means of the tension spring 18 to engage and support the work between them and these grippers are preferably offset at a particular angle so that when they engage one wall of the pail 19 and the carrier is rotated, the pail as it enters the tank is so immersed that the flux is caused to cover both the inside and outside surfaces thereof, to prepare these surfaces for the effective action of the molten galvanizing or coating metal, into which it is next passed, to act effectively upon the same.

The angle of offset of these grippers is also such that a pail as it emerges from the bath after having been carried therethrough is at such an angle that the molten contents will be automatically emptied therefrom back into the tank.

This drum or carrier may be rotated through the belt 21 running over the pulley 20 or by any other suitable means.

It will be noted that by my improved con struction of coating apparatus the work is supported by the carrier during its entire passage through the bath and is not permitted to come in contact with any of the surrounding or adjacent objects, thereby insuring a perfect coating of material to be deposited uniformly upon the work.

The arrangement of these grippers is such that they do not interfere with the coating of the material even at the point of their engagement with the work, and the work when removed shows no mark due to the contact of the grippers therewith.

I have shown this device as applied to the galvanizing operation of metal pails, but I do not wish to be restricted to the use of this device for this particular purpose for which it may be adapted; neither do I wish to be restricted to the particular form of grippers illustrated and described as any engaging means for supporting the work while being passed through the bath, will fall within the spirit of this invention, the scope of which is limited only by the terms of the appended claims.

I claim:

1. An apparatus for coating metal articles, comprising a tank, a carrier body mounted to rotate in said tank and arranged to form a barrier to confine the floating flux, and means on said carrier for receiving and conducting the work through the fiux and coating material in the tank as said carrier rotates.

2. An apparatus for coating metal articles, comprising a tank, a cylindrical carrier rotatably mounted to have a portion of its body extend into and transversely of said tank to form a barrier to confine the floating flux, and means on saidtcarrierfor grasping the Work to pass it through the flux and coating material in the tank as the carrier rotates.

3. An apparatus for coating metal articles, comprising a tank, a carrier rotatably mounted to have a portion extend into and transversely of said tank to form a barrier for confining the floating flux to one portion of the tank, and a set of spring actuated grippers mounted on said carrier for positively engaging the Work to support thehsame during its passage through the bat In testimony whereof I afiix my signature.

JOHN P. ODONNELL.
