Specification of Letters Patent.
IPatented May 15, 1906.
Application filed May 25, 1905. Serial No. 262,232.
To (tZZ whom it may concern:
Be it known that I, THOMAS C. DUFFIELD, a citizen of the United States, residing in Elmer, New Jersey, have invented certain Improvements in Bottle-Molds, of which the following is a specification.
My invention consists in improvements in bottleblowing machines of the class described and claimed in a patent,No. 736,708, granted me August 18, 1903, one object of the invention being to provide a bottle-mold of such construction that while using the mechanism for forming the neck of the bottle shown in said patent it shall be possible to blow a bottle by the use of the machine which shall have certain of its transverse dimensions less than those of the blank or form for primarily receiving the charge of glass and confining said charge during the neck-forming operation.
Another object of my invention is to provide a bottle-mold with side sections so constructed that they shall be free to move to permit the closed mold to contain a chargereceiving blank or form of greater transverse dimensions than those of the finished bottle and, further, in providing means whereby after the said form has been dropped out of the mold and before the bottle is finally blown said side sections may be moved together into the position, required to properly mold said bottle.
These objects I attain'as hereinafter described, reference being had to the accompanying drawings, in which Figure 1 is a perspective View of a bottlernold,'illustrating my invention as applied thereto. Fig. '2 is a vertical section illustrating the form as raised into the mold and the side sections thereof moved outwardly. Fig. 3 is a vertical section showing the form in its lower position and the side sections of the mold-in their'inner position ready to form a bottle. Fig. 4 is a horizontal section illustrating the form in its raised position with the. side. sections of the mold in their out positions. Fig. 5 is a horizontal section'illustrating the'form in its lower position and the a side sections of the mold in their inner posi- .tions, and Fig. 6 is a perspective view of a finished bottle.
' In the drawings herewith, A is the basepieceof my improved mold, which is carried 'upon a supporting-table, preferably of the construction shown in my patent above referred to. On the back of this plate is an upwardly-projecting spindle a, serving as the hinge-pin for the two halves B and B of the mold B. The base-plate has a downwardlyextending tubular portion a, in which is guided a vertically-movable blank or form D, having within its upper end a recess, as shown, and provided at its lower end with a roller d. There is also a vertically-extending slot (1 in the form, into which projects a setscrew d carried in the extension a of the base, the downward movement of said form being limited thereby.
In the 11 per face of the base-plate A is an undercut s 0t, in which slides a piece C, designed to form the bottom of the mold and having a handle 0. The slot is so placed that when the form D is in its lower position said piece when moved inwardly will be guided over the opening through which the form operates, the outward movement of said piece being limited by means of a stop 0. The two halves of the mold may be of any desired construction, the member B being provided with a fixed handle I) and a projecting lug 1) adjacent thereto, while the member B is provided with a handle 6 which has ahooked extension 6 designed to engage the lug b and clamp said two members of the mold together when they are in their closed position.
That portion b of each member of the mold des gned to form one side of the bottle is independent of the remainder and is free to be moved in and out. The rear faces of these movable portions are rovided with recesses for the reception of cy inders b eccentrically supported on spindles I). These spindles project above the top of their respective members of the mold and are provided with adjustably-placed handles, whereby they and their cylinders b may be turned so as to force inwardly the movable side portions 12 of the mold.
As illustrated in my patent above referred to, there is a vertically-reci rocable plunger E, which is movable into an out of the mold, and it will be further understood that the form D is moved into the mold or allowed to drop out of it by mechanism which, as it forms no part of the present invention, is not shown nor described. I
Under operating conditions with the form or blank D raised and the plunger-E also in its lifted position a definite charge of molten glass is placed within the cavity 6 of said form, after which the two halves of the mold are brought together and clamped;
As will be noted from Fig. 6, the bottle to I mold, the bottom portion of the mold being be formed is relatively flat and as a matter of fact is of much less thickness than the diameter of the form D. It will therefore be seen that in closing the mold this form, which is raised so that its properly-formed top edges meet the lower portion of the neck of the mold, forces outwardly the two movable sections or side pieces 1). Movement of the plunger E into the mold and into the body of glass within the form D forces the glass up into the neck of the mold, thereby forming the neck portion of the bottle. The plunger E is now raised and the form D is permitted to drop out of the mold, after which the bottom section C is moved inwardly to its pro er position. The handles 6 which are pre erably so adjusted as to project in lines at right angles to the lines of the front handles, are then turned toward the front of the mold, so that they are approximately parallel, thereby causing the cylinders 6 carried on their spindles, to force the movable sections 6 of the mold inwardly into their proper relative positions to form the bottle desired. Compressed air is then supplied to blow the bottle, which when finished has the ap earance shown in Fig. 6. The charge of g ass just after the'removal of the form D and the plunger E from the mold has the shape shown in Fi .3.
%rom the above it will be noted that I have by my invention rendered possible the blowing by machinery of bottles of such dimensions that they could not have been made by machines similar to that shown in my Patent No. 736,708 nor by any other machine with which I am acquainted, and I have therefore materially reduced the cost of the production of bottles of this class.
I claim as my invention 1. A mold having two side members, a bot-- tom member, structures respectively movable into the mold from its top and bottom, a movable section for each of said side members, said sections being placed to be forced outwardly by one of the structures and having means whereby they may be forced inwardly, substantially as described.
2. A mold having a sup orting structure, two side members hinge thereto, a relatively movable section forming a part of each side member, a form movable into and out of the mold and of such dimensions as to force said sections outwardly when the mold is closed, and cams for forcing said sections into position when theform is withdrawn from the mold, substantially as described.
3. A mold having two side members and a bottom member, a form recessed at its upper end and movable into the mold, each of the side members having a portion movable relatively to the remainder in a line substantially at right angles to the line of motion of said form to permit of its entrance into the recess of the form, and movable sections for the side members of the mold, said sections being movable outwardly by the form and having means whereby they may be moved inwardly when said form is removed, substantially as described.
5. A mold including side members each carrying a section movable in and out of the mold, a bottom member, a plunger movable into and out of the mold, and means for operating said sections of the side members to cause them to enter and be withdrawn from the mold, substantially as described.
6. A mold including a side member carrying a section movable in and out of the mold, a bottom member, a plunger entering the mold, and means for moving said side section in and out of the mold, substantially as described.
7. A mold including side members, movable sections for said side members, means for forming the neck of a bottle, with means for forcing said movable sections of the side members mwardly after the neck of the bottle has been formed, substantially as described.
8. A bottle-mold including side members having movable sections for molding a portion of the body of the bottle, a movable bottom section, a form movable into and out of the mold having a recess at its upper end, a plunger movable into said recess, and cams for moving said side sections of the mold inwardly when the form is withdrawn, sub-.
stantially as described.
9. A bottle-mold including side members, and means for forming the neck of the bottle before the body is blown, said means including a plunger and a structure in addition thereto movable into the mold, and said mold having relatively movable portions to permit of the entrance of said structure, substantially as described.
10. A bottle-mold including side members, a form movable into the mold, said form having a recess in its upper end and having said upper end formed to engage the upper porsize of said cavity after said charge has been to shaped, substantially as described.
In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
