Inthe drawings, 2 represents Vthe vertical My invention relates to the handling ofL bath-tubs in the enameling operationl and is designed to provide an -improved apparatus' by which the tub may be tilted into anydesired position under the control of the operator and by which the tub may also be inserted post of a crane having a lower rigid arm' 3,

which swings in a horizontal plane and'from which hangs a swiveled yoke 4, through which extends the shaft 5, having the end handle 6. The arm 3 is preferably provided with'tenf sion-brace 7, and above it is a second arm 8, which is pivoted at 9 to a loose collar 10, sur- The arm 8 .may therefore be swung both in a horizontal and a vertical plane, and its vertical -movement may be secured through the Wire rope'll, extending over the pulley 12 in'thearm, or by any other suitable connections. A link, 1,3 depends from the outer end of the arxn 8 and has a swivel connection .14 with a collar 15 which surrounds and supports the bearing 16. The shaft 5 is rigidly secured within the rear end of the two-part bearing 1,6, within which extends the rear portion of arotary shaft 17, which carries the fork proper, 18. Ball-bearings are preferably provided Within the bearing-sleeve fortheshaft 17, asindicated at 19, and the shaft is turned by worm-wheel 20, meshing with worm 2l on the short countershaft 22', having bevel-gear connection 23 with a shaft 24, actuated by a smallrotary motor 25. Compressed air or'otheractu'ating Fig. 2 is al fluid may be led to the motor by aiiexible conneetion, and the shaft 17,"witl1-its fork, may thus be rotated and locked in any adjusted position by the screw-gearing.

' AThe fork 18 is provided with trunnions 26, to theinner ends of which are secured longitudinal plates 27, which fit against the side vportions of the tub and are provided at their v frontand rear ends with loops or eyes 28, which areYA engaged by spring-catches 29,

IThese end shields'are formedtoyfit thetend uof the'tub and are provided with pulleys 31, over which Wind the cords or chains 32," which lpass through guiding-eyes 33 to the catches. By turning the hand-wheel 34 the cords may be tightened to disengage the catches 29 from lthe loops and allow the end shields to be removed after the dredging operation is perL formed. v j AToturn the tub in the fork to bring it to the different positions desired, I provide one of the trunnions vwith a worm-wheel 35, engaging a worm on shaft 37, carried in beary.ings at one side of the fork and having an actuating-handle 38.

In the operation of the apparatus the tub is inserted in the forks and the end shields are tilted, as shown in Fig. 3. The operator then turns the' tub to its diiferent positions by turning the handle 38 and by actuating the motor to `rotate the fork. The enamel is `dredged in the tub in these different positions. The tub and fork beingl raised or lowered by means ot`- the upper pivoted arm 8, the end shields 8 are removed, and the tub being brought to the normal horizontal position is shoved into the enameliug-muffle 39v by the operator using the `handle 6. When the enamel has been sufficiently heated to glaze the tub, it is drawn out of theinuifleand removed from the fork. f `rinothertublis then inserted and the operation is repeated.

The advantages of myinventionwill be' apparent to those skilled in the art, since a simple and effective apparatus is provided by which the tub may be tilted to its various positions with ease and rapidity. The fork itself, by which the tub is introduced to the lnuftle, is utilized for the dredging of the 'whose shanks are secured to end shields 30.

secured invplace, thus fastening the tub tol theforks, sothat it will not slide out when f I'do enamel instead of using a separate machine, as heretofore.

The mechanism and connections for tilting the tub upon the fork, for fastening it to the fork, as well as the other parts of the apparatus, may be modified without departing from my invention.

I claiml. In bath-tub-handling apparatus, a movable support carrying a tub-fork, mechanism for rotating the fork on its axis, and mechanism for tilting the tub to different angles relatively to the fork-axis; substantially as described.

2. In enameling apparatus, an overhead support, an enameliug-fork carried thereby, mechanism for raising and lowering the fork, mechanism for rotating the fork, and mechanism for tilting the tub to an angle with the axis of the fork; substantially as described.
