Patented Dec. 10, 1929 UNITED STATES PATENT OFFICE HAROLD J. RAYNES AND FRANK J. DENNING, OF SAN FRANCISCO, CALIFORNIA, AS-
SIGNORS TO ILLINOIS-PACIFIC GLASS CORPORATION, OF SAN FRANCISCO, CALI- FORNIA, A CORPORATION OF CALIFORNIA MOLD FOR FORMING GLASS VESSELS Application filed August 16, 1926. Serial No. 129,406.
This invention relates to molds for forming bottles, jars, and the like. Such molds as heretofore constructed are made in two hinged parts with the ring which forms the neck of the vessel being divided. This results in leaving a seam at the rim of the bottle or jar which is objectionable for many reasons. For instance, where a cap is to be screwed in place on a jar, the unevenness caused by the seam will interfere with the tight closure.
It is the object of the present invention to eliminate this seam on. the rim of the glass vessel, and this we accomplish by providing a continuous and integral ring to close the space between the plunger and the neck mold and form a smooth, even seat for the rim of the vessel.
One form which our invention may assume is exemplified in the following description and illustrated in the accompanying drawing, in which Fig. 1 shows a vertical central sectional view of a mold mounted in place on a turret;
Fig. 2 shows an inverted plan view of the one-piece ring and supporting arm therefor which serves to close the neck mold;
Fig. 3 shows a plan view of the parts illustrated in Fig. 1.
The present invention ap lies particularly to what are termed blan i or arison molds, as distinguished from the nishin mold. Usually these blank molds are inverted during the initial operation, and are provided with a mechanism for restoring them to upright position immediately before the transfor is made to the finishing mold. It is in these blank molds that the objectionable rim seams are formed. In the drawings a blank mold is illustrated as comprising two hinged body molds carried on arms 11. Coacting with the body molds are neck molds 12 also supported on arms 13. All of the arms are pivoted upon a pin 14 carried in a bracket 15, which bracket is rotated by gearings 16in a manner well known in the art, whereby the mold may be turned from its normal inverted position to upright position at the required time.
A plunger 1'? projects upwardly within the neck mold, and in prior structures it is usual.
tit
to provide ledges on the interior of the neck mold segments, so as to form a seat for the lip or rim of the jar or bottle. These ledges being integral with the neck mold and consequently split, are responsible for the objec tionable seams on the rim of the glass vessel.
In and by the present invention we dispense with these split or divided ledges and provide a one-piece closing ring 18 supported independently of the neck molds on a stationary arm 19. The said closing ring has a lip 20 fitting into a groove in the neck mold sections, for the purpose of insuring alignment. This closing ring is preferably carried on the arm 19 by means of a forked extension 21 fitting within a groove formed near the bottom of the ring. To prevent the ring from slipping out of the fork we provide a bail-shaped spring wire 22 fastened to the under side of the arm 19 and adapted to be sprung downwardly to release the ring when it is desired to remove it.
In the operation of the mold this one-piece ring 18 will fit within the neck mold sections and form a closure or seat between the neck mold and the plunger. This seat or closure, being in one solid piece, will leave no seams on the rim of the bottle or jar. The body and neck mold sections are free to open and close as in the ordinary practice, leaving the closing ring standing in place.
When the closing ring requires cleaning, as it frequently does, it can be quickly slipped out of the forked holder by pressing down on the bail-shaped spring wire.
Also, as a means of quickly detaching the body and neck mold sections "from the hinged arms, we provide a fork 23, slidably received in a slot on each arm 11 and 13. The tines of this fork fit into a groove in a pin 24, which pin is fastened to the mold section and extends through an opening in the supporting arm. The end of the pin has a small knob-like projection 25 which enters an opening in a spring leaf 26, the latter being carried by the supporting arm. To remove the mold section the operator retracts the spring leaf far enough to clear the projecting knob on the pin, where upon the forked holder can be slid backwardly so as tn disengage the pin.
Various changes in the construction and arrangement of the several parts herein described may be made without departing from the spirit of our invention as disclosed in the appended claims.
Having thus described our invention, what we claim as new and desire to secure by Letters Patent is:
1. A mold for forming glass vessels, comprising hinged sections for the body and neck of the vessel held in inverted position, a plunger co-operating with the mold sections to enter the neck thereof, a one-piece closing ring between the neck mold sections and the plungor to form a seat for the rim of the vessel, a stationary support for said closing ring, said stationary support comprising a forked arm fitting into a groove in the ring, and a spring latch for retaining the ring in the forked member.
2. A mold for forming glass vessels, comprising hinged sections for the body and neck of the vessel held in inverted position, a plunger co-operating with the mold sections to enter the neck thereof, a one-piece closing ring between the neck mold sections and the plunger to form a seat for the rim of the Vessel, and a stationary support for said closing ring, said stationary support comprising a forked arm fitting into a groove in the ring and a bail-shaped spring member surrounding the ring, arranged to be pressed therefrom to release the ring.
