'To t whu'l'n/ it may concern.-

Be it known that I ,WILLIS ELMER GUNNING, a citizen of the United States, residing at East Liverpool, in the county of Oolumbiana and State of Ohio, have invented new and useful Improvements in Pins for Holding Earthenware While Being Enameled, of which the following is a specification.

My invention relates to improvements in what may be termed pins for holding earthenware while being enameled. It is characterized for its extreme simplicity of structure and adaptability for its intended use and numerous other advantages which will appear in connection with the following description thereof.

It consists of the peculiarities of its structural outlines and constituency, substantially as hereinafter fully disclosed, and specifically pointed out by the claims.

In the accompanying drawings, illustrating the preferred embodiment of my invention, Figure 1 is a side elevation of the invention. Fig. 2 is a cross-section thereof produced upon either of the lines a a of Fig. 1. Fig. 3 is a plan view of the same. Fig. 4: is a partial section and partial side elevation of an oven, kiln, or saggar, with my pin in its practical-use position therein, said section being taken upon the line A B G of Fig. 5. Fig. 5 is a horizontalsection produced through the kiln or saggar practically in the plane of a set or series of the pins.

In the carrying out of my invention Imold or form a pin 1 of clayey material or a combination of clays, the same possessing the requisite hardness and toughness for its intended purpose. Said pin in general outline is angular or bent, comprising practically two underneath-braced limbs or members, although in a continuous piece, one occupying normally a horizontal position and being suitably held in a socket or hole in the vertical wall of the saggar, while the other limb or member stands at an obtuse angle to the former limb or member and faces or inclines downward and inward toward the interior of the saggar to form the rest or support proper for the article, as a washbowl, in treating the latter, as aforesaid. Said pin or support is also triangular or three-cornered in crosssection with its base presented downward and its upper central angle or apex efiective to engage the article, as in supporting the latter, a number, of course, of such pins being used to provide the necessary support therefor, as disclosed especially by Fig. 5.

It will be noted that with the article or washbasins or other piece of earthenware disposed or placed in the oven, saggar, or kiln, and of which former there is a number for treatment, the extreme outer normally upper edges of the basins are presented to and supported upon the apices or upper angles of the pins, thus providing for the minimum surface of contact between each pin and the articles being treated, practically avoiding the leaving any untreated portions or marks upon the articles, and whereby the latter may be presented in an inverted position to the firing or enameling process. This latter avoids the catching or lodgment upon and thereby the marring of the surface of the article, as would otherwise be the case, of any foreign particles or material which might be released and drop thereon from the inner dome-surface of the kiln or oven under the action of the firing or enameling process. Also itis noted that with the downward deflected or inclined members or limbs of the pins directly supporting the articles the latter may be nested or compactly arranged in the oven or saggar and yet be out of contact with each other, and thus provide for the treatment of a relatively increased number of articles at a single operation or one time, as well as prevent the liability of the articles sticking together in their initial condition or before the completion of the burning or enameling process. Itis still further observed that after the treatment or burning of one charge or batch of articles and their removal from the oven the pins may be withdrawn from their initial position in the oven-wall and be reversed for the like utilization of their other limbs or members, as in supporting another batch or charge of articles requiring like treatment. Again, it is remarked that but three of these pins are required for the support of each piece of ware, and that they will act during the aforesaid burning or baking operation as braces upon the suspension-bridge order, thus holding the ware or article practically in perfectly right lines and prevent the earthenware from becoming bent, crooked, warped, twisted, or wavy from the action of the heat or when passing through the glost kiln or oven. Other advantages will probably arise in the practical use of my invention which may not be now enumerated herein.

1 claim 1. A device of the character described, comprising the pin having a bent or angular outline.

2. A device ofthe character described, comprising the pin having practically two limbs or members one arranged at an obtuse angle to the other.
