PATENT OFFICE,

BOTTLE-MOLD.

SPECIFICATION forming part 0f Letters Patent NO. 487,498, dated December 6, 1892.

t Application filed July 13, 1891. Seria] No, 399,331. (No model.)

To all whom t may concern.-

Be it known that ITHoMAs W. SYNNo'r'r, a citizen of the United States, residing at Wenonah, in the county of Gloucester, State of New Jersey, have invented a new and useful Improvement in Bottle-Molds, which improvement is fully set forth in the following speciication and accompanying drawings.

My invention consists of a mold for forming glass bottles formed of sections which may be readily opened in both vertical and horizontal directions,the construction of parts being hereinafter fully set forth and claimed.

Figures 1, 2, 3, and t represent vertical sections of a glass-mold embodying my invention. Fig. 5 represents a horizontal section on line a; Fig. 2.

Similar letters of reference indicate corresponding parts in the several figures.

Referring to the drawings, A designates a mold for manufacturing glass bottles, the same consisting of the `mouth portion B, the neck portion C, the body portion D, and the bottom portion E. The bodyr portion is formed of vertical sections F, each of which ishinged or pivoted at top to the section C, the hinges or pivots being located near the inner parts of said portions D and O. The mouth and neck portions are formed in sections con- The under side of portion C is beveled downward from the exterior to near the interior thereof, and the upper side of the portion D is beveled upward from the exterior to near the interior thereof, by which provision a daring space G is formed between the neck and body portionsCand D.

H designates a hollow plug which is adapted to be inserted int-o the metal or glass to form the bore of the mouth and neck portions of a bottle and direct air into the metal or glass for forming the body portion of the bottle.

The operation is as follows: The bottom portion E of the mold is removed and the remainder of the mold, in closed condition, is inverted. The plunger in now inverted position is located in line with the center of the opening of the portion B of the mold. A quantity of molten glass is then poured into the mold (see Fig. l) and the plunger forced upwardly into said glass, as shown by the dotted lines in said ligure. Air is now forced through the plunger into the glass, so as to form a cavity therein, after which the bottom portion E is applied and the mold inverted. As soon as the glass has cooled sufficiently so as not to spread the sections F are quickly opened, so as to prevent sticking of the glass, (see Fig. 2,) which would occur if the mold and glass were not separated when the glass stops spreading, and then quickly closed, after which air is forced into the glass through the inserted plunger, (see Fig. 3,) whereby the glass fully drops and is properly blown into7 the form of a bottle, as will be seen in Fig. 4. The bottom portion E is now removed and the sections of the portion D are separated or opened, thus releasing the body portion of the bottle, after which the sections of the portions B and C of the mold are separated or opened, thus releasing the mouth and neck portions of the bottle; but,it' desired, the sections of the portions B and C may first be separated or opened and the sections of the portion D afterward separated or opened. In either case the bottle is released and made removable. As the sections F are hinged to the neck portion of the mold, they may be first opened, thus uncovering the body portion of the bottle produced, this requiring but a slight motion, the latter being from bottom to top and limited by the walls of the space G. rJhen the neck and mouth sections C and B may be partially opened in lateral direction, this also requiring a slight mot-ion, as the neck and mouth of the bottle are, as is well known, of less diameter than the body portion. Again, should there be any sticking of the bottle to the mold this may be overcome by applying superior power to the section or portion of the mold where the sticking occurs without necessarily moving the other section; but in all cases the greater bulk or body of the bottle may be rst released, after which those of less diameter-viz.,the neck and head.

The bottom E is made detachable from the body of the mold, it being connected therewith by a hook or eye or other device, so that it may be disconnected from and again connected with the body, according for requirements.

IOO

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. A bottle-mold having neck and mouth portions and a body portion, consisting of sections, each of which is hinged to the respective neck-section, a fiaring space being formed between the body and neck sections, substantially as described.

2. A bottle-mold consisting of a body portion of vertical sections, a neck portion pivoted to the top of each of said vertical sections near the inner part. of said neck and body, and a sectional mouth portion hinged to the said neck, the under side of the neck portion being beveled downwardly from the ex-
