PONTIL-HEAD.
Application filed January 14, 1909.
Specification of Letters Patent.
Patented Mar. 29, 1910.
Serial No. 472,346.
T 0 all whom it may concern:
Be it known that I, FRANK WARNER, a citizen of the United States, residing at Butler, in the county of Richland and; State of Ohio, have invented anew and useful Pontil- Head, of which the following is a specification.
This invention relates to glass manufacture and more particularly to a pontil head especially designed for use in the manufacture of milk bottles and similar containing vessels. v
Heretofore, in the manufacture of glass articles the pontil heads employed for gathering and drawing the molten glass have been made of metal, which material often melts and causes particles or iron to mix with the glass and produce dark s ots in the ware and otherwise injure and iscolor the same. i
The object of the present invention is to prevent discoloration of glass articles during their manufacture by providing the pontil rod with a head formed of sillca or other refractory material and which is capable of performing all of the functions of the usual metallic head and which will not disintegrate and mix with the glass under the intense heat to which the pontil head is subjected.
Further objects and advantages will ap pear in the following description, it being understood that various changes in form, proportions and minor details of construction may be resorted to within the scope of the appended claims.
In the accompanying drawings forming at art of this specification :-Figure l is a si e elevation partly in section of a pontil rod constructed in accordance with my invention.' Fig. 2 is a view showing the head in section. Fig. 3 is a transversesectional view taken on the line 33 of Fig. 2.
Similar numerals of reference indicate, corresponding parts lin all of the figures of the drawings.
' The pontil head forming the subject matter of the present invention includes a rod or shank 5 preferably circular in cross section, as shown, and having its upper end threaded at 6 for engagement with a handle 7.- The lower end of the rod is extended laterally to form an enlargement constitutaccidental displacement of the same. The
head may be of any desired shape or contour but in its preferred embodiment is provided with convex upper and lower faces 10 and 11 and an intermediate annular straight portion 12 disposed parallel with the longitudinal axis of the rod 5.
Attention is here called to the fact that the head being formed of concreteor other silicious material presents a roughened surface to the molten glass thus causing the latter to readily adhere to the head when handling the glass during the manufacture of bottles, jars and similar articles. It will also be noted that b reason of the fact that the head 9 is forme of refractory material, the latter will.withstand a very high tem;
.perature without disintegratingand commingling with the molten glass, thus preventing the formation of dark spots in the glass or other discoloration of the same,
which invariably results when metal heads are used for this purpose;
It will of course be understood that the heads may be made in different sizes and shapes and formed of any suitable material capable of withstanding the intense heat to which it is subjected without disintegration or fusion. Having thus described the invention what is claimed is k- 1. A device of the class described including a rod having one end thereof threaded and its opposite end provided with an enlargement constituting an-anchoring device,
a handle engaging the threaded end of the rod, and a headmolded on the anchoring device while in a plastic state and formed of refractory material.
2. A device of the class described includihg a rod, and a head secured to one end of as my own, I have hereto aifixed my signathe rod and formed of refrzactfry material, ture' in the presence of two Witnesses.
said hea having up er an ower convex i faces and an interme iate annular edge dis- FRANK WARNER 5 posed garallel with the longitudinal axis of Wltnesses:
the r0 LE ROY L. STIOHLER,
In testimony that I claim 'the foregoing RALPH O. GRUBB.
