PRESS-MOLD F0 HOLLOW ARTICLES.
SPECIFIGATIGN forming part of Letters Patent NO. 696,430, dated April 1, 190 2. Application filed July 12, 1901. Serial No. 68,008. (No model.)
To a-ZZ whom it may concern.-
Be it known that I, WILLIAM J. GREEN- WOOD,of Tarentum, Allegheny county, Pennsylvania, have invented a new and useful Press-Mold for Hollow Articles, of which the following is a full, clear, and exact description, reference being had'to the accompanying drawing, forming part of this specification, in which the figure is a sectional side elevation showing my improved press-mold with the blank in place.
My invention relates to the forming of hollow glass articles formed by pressing and then expanding the pressed'blan'k, and especially to the making of bottles and jars, and is designed to provide an improved press-mold which will do away with the annular seam or recess usually formed on the outer surface of the upper bulb-shaped enlargement of the neck and to prevent the burning out of the upper parts of the mold and afford a simple and effective construction.
In the drawing, 2 represents the body of a press-mold, and 3 a two-part hinged 1nolclring which seats upon the top of the pressmold.
4 is a top collar or plate through which the plunger 5 is reciprocated during the pressing operation. This plate is provided with an annular projection 6 around the central hole for the plunger, this projection forming a groove or recess in the mouth of the bottle where this recess is desired. The joint between the plate and the mold-ring extends" vertically from the top of the recess forming the enlargement around the mouth of the' bottle or jar, as shown at 7. Above this joint the plate is provided with an enlarged portion 8, which fits within a corresponding recess in the mold-ring, the faces of these parts being preferably beveled or inclined to guide them into registering position.
The pressing operation is carried out in the usual manner, and there being'no horizontal joint between the plate and the mold-ring at an intermediate point of the neck a seamless neck is formed. The pressed blank is then expanded in a well-known manner by blowing or otherwise.
The advantages of the invention result from the use of the collar or mold-ring having a curved recess in connection with a top plate forming the vertical joint at the top of the neck and havinga portion enteringthe neck.
Many variations may be made in the form and shape of the mold, the mold-ring, and plate, as well as the shape of the article, without departing from my invention.
1. A press-mold for bottles or other hollow articles having a mold-ring centered thereon, atop plate having interfitting projections and recesses with the mold-ring, said plate forming a joint with the mold-ring at the top of the bottle, and having a'projection entering the month of the bottle, and a central hole in said plate for the passage of the plunger for pressing the bottle; substantially as described.
A press-mold for bottles or jars, having a mold-ring centered thereon and provided with a globular recess arranged to form a projection at the upper end of the neck, a
top plate having interfitting projections and recesses with the mold-ring, said plate fOlIlling a vertical joint with the mold-ring at the top of the bottle and having a projection enterin the mouth of the bottle, the plate also having a central hole for the passage of the plunger for pressing the bottle; substantially as described.
In testimony whereof I have hereunto set my hand.
