ENAM ELlNG-TAB LE.

SPECIFICATION forming part of Letters Patent No. 558,339, dated April 14, 1896.

Application filed August 22, 1895.

To all whom it may concern.-

Be it known that I, JAMES W. ARROTT, Jr. a citizen of the United States, residing at Allegheny, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Enameling-Tables; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same. 1

My invention has relation to enameling-tables, and relates particularly to tables for heavy metallic objects, such as iron bath-tubs, tanks, sinks, &c. and my invention has for its object the provision of novel means by which the article to be enameled can be easily and speedily placed in any desired position, so as to enable the operatives to perform their work with ease and despatch.

While I have stated that my invention relates to enameling-tables, I wish it to be understood that my invention comprehends an adjustable revolving table for handling either regularly or irregularly shaped vessels or articles for the purpose of accurately and rapidly or slowly adjusting them to any desired position necessary for subjecting their various surfaces to any desired treatment when either hot or cold.

In carrying my invention into effect I provide a revoluble and tiltwise-adjustable table mounted on suitable supports and provided with novel means for holding the article in position while being treated, for revolving the table, for adjusting the same to any desired angle, and for protecting parts of the surface, when necessary or desirable, during the enameling or other operation.

My invention consists in the novel construction, combination, and arrangement of parts hereinafter described.

Referring to the accompanying drawings, which illustrate my invention as applied to a table for enameling cast-iron bath-tubs, Figure 1 is a plan view of the table with a bathtub in position thereon. Fig. 2 is a side elevation. Fig. 3 is an end View of the same,

and Fig. i a vertical transverse sectional view on an enlarged scale.

A A designate the end framings upon which the table is supported and which may be either Serial No. 560,151. (No model.)

bolted to the floor or upon a suitable movable A carriage or truck.

J ournal-bearings B B are formed on the upper ends of the framings A A and receive journals 0 O, projecting from the ends of a heavy swinging beam D, the longitudinal axis of which is some distance below the longitudinal axis of the bearings .C C. At the center of the beam D a strong vertical shaft E is arranged in suitable bearings, and upon the lower end of said journal beneath the beam D a worm-gear F is fixed and meshes with a worm G, keyed upon a horizontal shaft II, which has hearings on each side of the worm in hangers I I, that are bolted to the beam D, and has a third bearing in a box K, arranged on the side of a lever D, that extends laterally from the lever D. The shaft H extends slightly beyond the lever D and is provided with a handle II, by means of which it may be turned.

At a suitable point on the beam D a depending arm E is fixed and an adjustable weight E is carried by said arm, being fixed in any position to which it may be adjusted by a setscrew The purpose of the weight E is to counterpoise the weight of the article being enameled, and while the adjustment of the counterpoise-weight is not necessary when the articles being operated upon are of approximately the same weight such adjustment will be found necessary when it is desired to opcrate upon other articles varying considerably in Weight from those previously operated upon.

The laterally-projecting lever D is braced to the beam by a diagonal brace D and provided with a handle D Upon the inner side of the lever D is arranged a latch comprising the pivoted handpiece d, the rod d, spring d bell-crank lever (Z and sliding pin or catch d the handpiece d and bell-crank lever 01 being pivoted to the lever d and to the rod d, and the catch (Z being pivoted to the bellcrank lever d Upon the inner side of 'the framing A an arc-shaped plate d is fixed, said plate being formed with notches 61 into which the catch d" is forced-by the spring 61 when the handpiece d is released.

The vertical shaft E has attached to its upper end a cross-beam L, that supports a large metallic plate L, said plate being firmly attached to the beam L by braces L L The beam L is formed with a longitudinal slot L in which are fitted slide-bars L formed with slots L Bolts L pass through the beam L and through the slots L in the slide-bars L and serve to guide the said slide-bars in their seats, while set-screws L serve to hold the slide-bars in any position to which they may be adjusted. The table M is provided with slots on m at each end, and through the said slots pass the shanks on of clamps m projecting upwardly from the slide-bars L Near each end and on both sides of the beam L are arranged braces lll M that extend laterally toward and near to the edge of the table M and are secured thereto by bolts M M I-Ioles are bored at intervals through the table and through the lateral braces M M and through these holes are passed the down- \mrdly-projecting ends at n of horizontal sides braces or clamps N N. Several such holes n n are provided, so that the side braces N may be adjusted to different positions to accommodate different sizes of articles. Curved arms 0 0 project laterally from the ends 01 n of the side braces N, and from the ends of the said curved bars are hung swinging plates P P.

The apparatus constructed as described is operated in the following manner: Where it is desired to use the apparatus for handling articles to be enameled or otherwise treated, the structure is erected, or where it is mounted on a movable truck, the apparatus is moved to a suitable position at the furnace or place where treatment may be applied, the article to be operated upon is taken from the furnace or elsewhere, as the case may be, and is laid upon the table M, and if it is desired to change the position of the article for treatment in a furnace the handle H is turned until the table M has made sufficient revolution, when the article is lifted from the table and put back into the furnace. \Vhen the article is to be enameled, the side clamps or braces N N are fixed in position, their ends being inserted in such of the holes 01 0 in the table as will allow of the article passing between the clamps, and the slide-bars L L so adjusted as to permit the article to be deposited between them. The article is then drawn from the furnace and lowered upon the table, so as to rest between the side clamps N N and the end clamps M M. The operator now grasps the handle D and releasing the catch d, by means of the handpiece (1, he raises the lever D, thus tilting the table L. Zhen the table has assumed the desired angle of inclination, the handpiece d is released and the catch (1 takes into one of the notches (Z in the arc-shaped plate I), thus holding the table in the position to which it has been turned. The lower inside surface of the article as well as the upper outside surface of the article, when desired, is, by this movement of the table, brought to a horizontal or nearly horizontal position, and the enamel can now be readily applied by operatives standing by the side of the table. The table is now caused to revolve on the shaft E by turning the handle I-l until the end of the bath-tub is in a horizontal or substantially horizontal position, whereupon the enamel is applied to the end either inside or outside, as desired. The revolution of the table is continued until the other side and the other end of the article have been successively brought into a horizontal position, when the operator, grasping the handle D and handpiece (:1, releases the catch (2* and draws the handle down until the table has assumed its normal or horizontal position, when the bottom of the article can be treated, and when completed the article may be lifted from the table and disposed of as desired.

Where tubs or other articles having rims are to be enameled, the enamel is usually applied to that part of the rim which is uppermost when the table is tilted; and in order to prevent the enamel from falling upon and adhering to the outside of the article I have provided the swinging plates I, one of which, when the table is tilted, will swing around, so that its inner edge comes under the inside of the rim of the article, so that any enameling material which may fall over the edge of the rim will be caught by the plate and prevented from falling upon the outside of the article.

Having described my invention, I claim- 1.
