CHARLES EDWIN BLUE, OF WHEELING, WEST VIRGINIA.

. MACHINE FOR THE MANUFACTURE OF NARROW-NECK GLASSWARE.

SPECIFICATION forming part of Letters Patent No. 687,597, dated November 26, 1901. Application filed August 4, 1900. Serial No. 25,899. (No model.)

To all whom it may concern.-

Be it known that I, CHARLES EDWIN BLUE, a citizen of the United States, residing at Wheeling, in the county of Ohio and State of West Virginia, have invented new and useful Improvements in Machines for the Mannfacture of N arrow-Neck Glassware, of which the following is a specification.

My invention relates to improvements in machines for the manufacture of narrowneck glassware, and pertains to a machine ineluding an inverted press-mold with a yielding removable bottom and an upright blowmold, all of which will be fully described hereinafter.

In the accompanying drawings, Figure 1 is an edge elevation of a machine embodying my invention, the press-mold being shown in vertical section. Fig. 2 is a front elevation, the press and blow molds being shown in vertical section. Fig. 3 is a detail view show ing the stops for limiting the oscillation of the press-mold.

Referring now to the drawings, A is a base, from which projects a standard B. An in- Verted press-mold C is supported by this standard B in any suitable manner and may be either a non-reversible or a reversible pressmold, as desired. As here shown, it is a reversible press-mold and is supported through the medium of a pin or bolt D, which passes loosely through the standard B and has its inner end screwed into a suitable mold-lug E.

This mold-lug E is provided with the oppositely-projecting pins, shoulders, or projections F, which are adapted to engage with the pins, shoulders, or projections G extending from the adjacent face or side of the standard B and which serve to limit the oscillating movement of the press=mold when it is oscillated to reverse its former position. One of the lugs, pins, or shoulders G serves, through the medium of one of the pins F, to limit the movement of the mold in one direction and the other set of pins serves to limit the mold when turned in the other direction, as illus trated in Fig. 3. A plunger-rod H moves through a suitable guiding-arm I and carries aplunger J at its upper end, which is adapted to enter the press-mold and to form a blank which will blow a finished article with an evenly-formed bottom.

K is a plunger-ring which is adapted to co act with the mouth of the mold O for the pur a row-neck mold the mouth of the mold is too narrow to permit the molten glass to be passed therethrough to the interior of the mold for forming the blank, and hence the bottom end of the mold is open and a removable bottom provided therefor, whereby the bottom may be removed to permit free access thereto for the ready placing of the glass within the mold.

In the formation of narrow-neck bottles a very narrow or slender plunger is necessary, for the reason that the mouth of the narrowneck mold will only permit a slender plunger to pass therethrough. Also in the manufacture of all glass articles the charging of the mold with glassware so far as the amount of glass supplied thereto is concerned is guess work, and hence uneven quantities of glass are supplied to the mold in the several charges thereof. It is found that owing to the slender ness of the plunger a slight variation in the amount of molten glass fed to the mold will cause a very large variation in the depth at which the plunger can enter the mold, for the plunger is stopped as soon as the mold is filled by the glass and plunger combined. Hence the Variation in the charges of glass to the mold causes a large variation in the distance that the plunger is moved within the mold, and the consequence is unevenly-blown bottoms.

The bottom L is made yielding for the purpose of permitting the plunger to enter the mold always a predetermined distance, and a weighted lever M accomplishes this result, one end of the lever being pivotally connected at the point N with the standard B and the opposite end of the lever carrying a suitable weight P. The weight is of such size and so positioned upon the lever M that it will hold the bottom to position against movement during the pressing operation until the mold has become filled, when the further movement of the plunger will cause the bot tom L to retract against the pressure of the said weighted lever.

Projecting upward from the leverM is a bar Q, which slides through an arm R, projecting from the upper end of the standard B, and this arm R is provided with a gravitylocking eccentric S for the purpose of looking the said bar and in turn holding the bottom L to its retracted position. A standard a also projects from the base A and carries a suitable open-and-shut blow-mold b, and a blow head or ring a is adapted to coact with the upper end of the mold for the purposeof blowing the pressed blank to a finished form.

Attention is directed to the fact that the two parts of the press-mold O are separately pivoted through the medium of suitable pins or pivots d, whereby the bottom L may enter the mold without interference from the pivotal connection of the two parts of the mold, which could not be the case if the two parts of the mold were hinged upon a single pin.

In the operation of my invention the plunger is carried to its downward limit of movement, and hence withdrawn from the mold through the medium of any suitable handleas, for instance, a handle e, connected to the plunger=rod and extending therefrom. The removable bottom L is then withdrawn from the press-mold by an upward pressure upon the lever M, when the locking-eccentric S will hold it in this elevated position, as shown in dotted lines, Fig. 1. A charge of molten glass is then deposited within the press-mold, the removable bottom carried to position within the press-mold, and the plunger then inserted within the mold. As soon as the mold becomes filled the further movement of the plunger will cause a retraction of the bottom L for the purposes heretofore explained. The pressed blank is then removed from the press-mold and placed within the blow-mold, and in accomplishing this the press-mold may or may not be oscillated for the purpose of carrying the pressed blank to an upright position, as may be desired or found most convenient. I prefer to have the press-mold reversible,as before stated,whereby the blank can be carried to an upright position corresponding to the position of the blow-mold, though this is not essential to the essence of my present invention.

Having thus described myinvention, what I claim, and desire to secure by Letters Pat ent, is

1. In a machine for the manufacture of glassware, the combination of an invertible press-mold, a removable bottom therefor disconnected with the said mold and movable out of line of travel of the said mold when being inverted, and an upright blow-mold.

2. In a machine for the manufacture of glassware, the combination of an invertible press-mold having a yielding and removable bottom, and a non-invertible upright blowmold. a

3. In a machine for the manufacture of glassware, the combination of an invertible press-mold having an open bottom end, and a freely-movable weighted and removable bottom for said mold.

4:. In a machine for the manufacture of glassware, the combination of an invertible press-mold, a removable bottom disconnected with the press-mold, and a locking member independent of the movement of the said mold for holding the said bottom in its removed position.

5. In a machine for the manufacture of glassware, the combination of an inverted press-mold having a movable bottom, means for automatically moving the bottom into op- 8o erativeposition, and a locking member for holding the said bottom in its moved position.

6. In a machine for the manufacture of glassware, the combination of an inverted press mold having a depressed verticallymovable bottom, and a locking member for holding said bottom in its moved position.

7. A machine for the manufacture of glassware comprising an inverted press-mold having a removable bottom, an independent up right blow-mold, an upwardly-acting plunger for said press-mold and a downwardly-acting blow-head for the said blow-mold, the blowhead being independent and acting irrespective of the said removable bottom and plunger.

In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
