FRANK J". CARPENTER, OF EAST ORANGE, NEW JERSEY.

ENAMELING APPARATUS.

Application filed August 1, 1918.

To all whom it may concern:

Be it known that I, FRANK J. CARPENTER,

a citizen of the United States, and a resident of East Orange, in the county of Essex and State of New Jersey, have invented a new and Improved Enameling Apparatus, of which the following is a full, clear, and exact description. 2

Among the principal objects which the present invention has in view arez to facilitate the handling of articles being coated or enameled; to avoid unnecessary soiling of the hands of the operator; to reduce the time devoted to distributing the coating of enamel on articles being treated; to avoid spotting the coating during the distribution thereof; and to reduce the labor incident to the operation of enameling.

Drawings.

Fig. 2 is a detail view showing in cross section a swinging clamp arm and operating lever therefor, the section being taken as on the line 2-2 in Fig. 1;

Fig. 3 is a detail view showing a grasping arm and adjustable rod for supporting the same;

Fig. 4 shows a side view of a modified form of the invention, said form being particularly adapted for engaging the inturned rims of articles to be treated;

Fig. 6 is a vertical section, the section being taken as on the line 66 in Flg. 5.

. Descm'p t'ion,

Heretofore the art ofenameling has in part entailed the use of a vat containing the liquid enamel or paint. Articles to be coated have. been hand dipped therein. The operation of lifting the article from the vat has manipulated the same for the purpose of flooding ricover ng wit out bru m r the entire surface of said article. Consider- Specification of Letters Patent.

Serial No. 247,789.

able skill and care have been required to perform the operation described successfully. Incident to the handling of the article, finger marks or spots have occurred thereon. These spots have been eradicated after the article has been deposited on drying pegs provided for that purpose preliminary to placing the articles in the baking oven.

This operation of necessity has been objectionable in that the hands indubitably become soiled with the paint or coating. F 11rther, more than usual care has been required when applying additional paint or coating to cover or obliterate finger marks or impressions in the said paint or coating.

These disagreeable features are overcome when using the present invention. To enamel a pan, such as indicated by the numeral 11 in Fig. 1 of the drawings, the operator presses the hook-ended yoke 12 until the hooks 13 and 14 of the yokes 12 and 15, are spread to receive therebetween the curled rim of the pan. 7

To spread the yoke 12, the arm 17 of which it is an integral part, is swung on the pivot 18, which connects the said arm with the bracket 19 of the rotary shaft 20. To so swing the arm 17 the hand lever 21 is grasped by the operator and drawn beyond the shaft 20. Theofi set extension 22 of the said lever has at the end thereof a yoke 23, which straddles the arm 17, as shown best in Fig. 2 of the drawings. Normally the arm 17 is held above the line of the reach bar 24, by means of a pull spring 25, which is anchored on said bar 24, and engages the hook 26 on the arm 17 adjacent the yoke 12. When the arm 1'1 is fully depressed by the operation of the lever 21, the axis of the spring 25 passes below the horizontal plane of the bar 24 and pivot 18. The pull of the spring in this position holds the yoke 12 in itseXtreme spread disposition.

-f To accommodate utensils of various diameters, the reach bar 24 has a series of perforations 27. The yoke 15 is connected to the reach bar 24 by means of a short standard 28, whichat the lower end has a square col ar; 2% t o gh hi h p sse a pin o screw 30. The pin or screw 30 extends through the perforations 27 with which perforations in the square collar coincide.

When operating with an apparatus such as described, the operator adjusts the yokes l2 and 15 to the pan 10, the hooks 13 and 14being engaged with the rim 16 thereof. When the lever 21 is released, the spring 25 holds the yoke 12 firmly engaged with the said pan. The operator then engages the stationary handle 21 and tips the pan and the ends of'the yokes 12 and 15connected therewith into the liquid enamel until the pan is thoroughly covered. On lifting the pan or utensil, the motor or operative conmotion between the same. and the flexible shaft 32 is started or made. The shaft 32 is operatively connected with the shaft by means of a coupling 33, in which the two shafts are firmly held by set screws 34. vThe pan or other article is now whirled with greater or lesser violence and speed, the degree or rate of which is determined.

It willv be noted by reference to Fig. 1 of the drawings that the pan or other utensil is slightly'uplifted at one edge or at the edge engaged by the yoke 12, which produces a rotation of the utensil of a wabbling character, which promotes the flowing covering action of the enamel. When the article has been thoroughly covered with the enamel, it is placed on drying pegs. The operator now engages the lever 21 and by pressing the same rocks it on its pivot 35, with the result that the yoke is spread away from the yoke 15, releasing the utensil held therebetween. It will be noted that the edges of the hooks" 13 and 14 having engaged the rim 16, the uncovered spots are exceedingly minute and easily covered by drawing the paint or enamel over the untouched spots, requiring no added enamel with the usually attending lap. 7

When employing the modified form of the invention shownin Figs. 4 to 6, inclusive; the rim 36 of the utensil 37 is grasped from the inside by hooks 38 on the yokes 39. The yokes 39 are attached to bent arms 40. *The'arms 40 are pivotally connected by a pin 41. The pin 41 extends through a bifurcated coupling 42 at the end of the rotary shaft 43." The shaft 43 is, connected to the coupling 33 by meansof set screws 34, as in the preferred form shown in Fig. 1' of the drawings The arms 40 arecontracted and spread by means of a slide link 44. The link- 44 is pivotally connected by a pivot 45 with spreaders -46,"each of which is pivotally connected-by a' "pin 47 with one of thearms 40.' The linkf 44 ha'san elongate'd'slot 48, which engages the pin 41 in guided relation thereto. At the lower end of thelink 44;; alip 49 is outturnedto be engagedby the operator for'raising and lowering the link 44 and spreaders 46 connected therewith.

The form of utensil for which the modified form of the invention is particularly adapted; are such as hot-water or other kettles, where the diameter of the opening formed by the rim 36 is practically determined and fixed. 7

When the operator engages the lip 49 to draw the link 44 and spreaclers 46 connected therewith toward the handle 31, the spreaders 46 contract the bent arms 40 and yokes 39. The yokes are then introduced within the circle formed by the rim 36 to be spread by the operator moving the link 44 outward. The arms 40 are then spread until the hooks 38 operatively "engage the rim 36, and the link 44 is forced outward until the lower end of the sloti48 engages the pin 41. In

this position it will be found that the pivot 45 is lifted above the plane coincident with the pins 47. The strain on the members coordinated operates to lock the members in the position to which they have been moved. The operation of the modified form of the invention is to all intents and purposes, the same as that above described as when using the preferred form of the invention.
