/srncrrcArIoN forming Aia-fe er Letters Patent No. 693,130, dated February 11, 1902. Application tiled August 18,1899. Serial No. 727,719. (No model.)
To all whom, t may concern:
Beit known that we, JONATHAN HALEY and HARRY 1-1. BRIDGWATER, residents of Akron, in the county of Summit and State of Ohio, have invented certain new and useful Improvements in Machines for Forming Glassware; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it pertains to make and use the same.
The invention relates to machines for forming glassware, and is especially suitable for forming narrow-mouth ware, such as beerbottles. It has for its objectto increase economy, efficiency, and certainty of action and also to avoid undue complexity and cost of construction.
The invention consists in the devices and combinations hereinafter described and then pointed out.
In the accompanying drawings, Figure 1 is afront elevation of the improved machine. Fig., 2 is a partial rear elevation. Fig. 3 is a perspective of devices for supporting and moving the sections of a finishing-mold, the sections being omitted. Fig. 4 is a plan of the inner parts of the same. Fig. 5 is a side elevation, partly in section, of the machine. Fig. 6 is a perspective of the neck-mold sections and their supporting and operating de- Fig. 7 is a plan of a cam-plate for moving the neck-mold sections. Fig. 8 is a perspective of one of said sections. Fig. 9` is a horizontal section of the machine, taken above the molds and showing the finishingmolds open and the neck-molds closed. Fig. 10 is a longitudinal section of a press and neck-molds. Fig. 11 is a longitudinal section of a blow or finishing mold and neck-mold.
Numeral 1 denotes the frame of a carriage, and 2 denotes a table or platform in which are supported a plurality of press-molds 3 and blow-molds 4. As shown, the latter are sectional, the press-molds being preferably entire. To the table are fixed posts or guides 5 and 5x. The latter are connected by an adjustablyfixed cross-bar 6, which supports vices.
blowing devices. The posts are also connected in pairs by top bars 7.
8 and 8x denote cross-heads sliding on the posts 5 and operated at will by alc'ver 9, fixed eccentricallyin the present instance to one of a pair of disks 10, fixed on a rocking shaft 11.
12 denotes connecting-rods eccentrically pivoted to the said disks and loosely connected to the cross-head 8, the construction being known in the art as a means for operating the plungers of glass-pressers.
The cross-heads 8 and lX are connected, and in the latter are adj ustably secured a plurality of rods 13, each having a plunger 14, adj ustably connected to its post and in proper alinement with a press-mold 3.
In operation the press-molds are raised from an inoperative to an operative position and then held stationary while a plunger is forced into one of them, the press-molds being subsequentlylowered and the plungers retracted,
these operations being effected by the movement of the lever 9, that draws down the cross-heads 8 and 8x. The lifting of the pressmolds to meet the plungers is effected by cams 141, fixed on the shaft 11', said cams having bearing-faces 14 and 14" of suitable form to first raise the molds and then to rotate under them without further vertical movement of said molds. The parts or faces 14" of the cams are circular and correspond to this latter part of the operation. f
15 denotes pistons movable in cylinders 15x to raise the molds, and 16 are slots in the cylinders for the passage of the rocking cams 14X.
The blow-molds are raised by cams 23, loose on a shaft 23x, which cams are separately actuated by levers 24.
On the platform 2 are fixed small posts 17, provided with adjustable parts, such as sleeves 18. Set-screws are denoted by 19, and mediately supported by said posts and directly by the sleeves are ways for neckmoldsupporting plates 2l. A handle for moving a plate, a neck-mold, and a pressed article suspended by said moldis denoted by 22.
25 denotes the sections of a three-post neckniold fixed at 25X to feet or supports 26, sliding in ways 26X. They are moved back and forth by a suitably-slotted plate 27, provided with a handle and having its slots engaged with pins 25', fixed in the sliding supports 26.
28 denotes one of several plates suspended by rods 29 from plates 30, fixed to rods 13. The latter support the plungers and connect the movable cross-bars 8 and 8 in a usual manner.
When a plate 28 is lowered upon a plate 2l by the descent of the cross-heads which carry the supporting-rods, said plates 28 are held on the plates 2l, while the plates 30 are moved down on said rods 29 as the plunger enters the mold. Springs 3l are compressed by this operation and act as a cushion, and they subsequently react to lift the plates 30 on the rods 29.
The glass that has been pressed in a mold 3 is relieved from said mold .by its descent when its lifting and supporting cams permit the pistonsl to drop, and the plunger being lifted said glass or pressed article remains suspended by the neck and is moved by suitably sliding the neck-mold plate under the blower and in situation to be embraced by a blow-mold.
The blow or finishing mold 4, composed of two sections 32, is closed upon the suspended glass after the latter has been moved to a proper situation, as stated, by means of a rotating cam-plate 33, (indicated by broken circle in Fig. 4.) Said plate has slots 33X to engage pins 34, fixed in the mold-sections and mold-section supports 35, as shown in Fig. 1l. The rotation of the plate 33 is effected by a handle 33V, which, together with plate 33, plays in a recess 33, formed in the under side of the fixed plate 33W, which latter plate also has a raised part 36X, having shoulders 36, over which the mold-section supports 35 tit, as best shown in Fig. 3. The proper movement of plate 33 moves the mold-sectionsupports by means of the engagement of its slots 33X with pins 34, and said movement is kept in a right line by the shoulders 36, the pins 34 also moving in slots 35x, situated in plate 33W.
37 denotes a pipe communicating with a.
source of air under pressure, and 38 are branches to discharge air into the pressed glass after its transfer to and inclosure by the blow-mold sections.
39 is a valve, one for each blowpipe, to control the air-blast. The valve-stem 40 is connected to an adjustable rod 41', dependingin the ascending path of the blowmold and adapted to be lifted by the ascent of the said mold when forced up by a cam 23, acting on a piston 15. Upon the descent of said mold the valve is closed by air-pressure.
To charge the metal into a press-mold, the
latter is drawn off from the upper end of a piston l5 and from between suitable stops, such as 15', on the table 2 in front, and the glass dropped therein. The mold .is then pushed back against the stops and the presssealed mold raised, so that it embraces the previously-closed neck-mold', theupp'eredge of the press-mold being preferably chamfered, as indicated at 3x. As the mold 3 is pushed up it forces the metal into the neck-mold. The descending plunger opens the bottleneck and expands the glass laterally into engagement with the neck-mold, vso that upon dropping the body of the pressmold and lifting the plunger the neck-mold and partiallyformed article can be slid back to be inclosed bylthe blow-mold, as above explained. The operator who manipulates the blow-mold devices having finished the article lowers the mold, opens both sectional molds, removes the finished article, closes the neck-mold, and returns it to the front.
It will be understood, although all the pressmold pistons are simultaneously-lifted, that in practice but one press-mold will be in situation to be raised, the others being on the front part of table 2. Obviously a larger number of press-molds could be provided and two or more press-molds simultaneously operated.
The construction provides for dropping metal into a wide (or body) part of a pressmold and subsequently lifting said mold,with the edect to force the dropped metal into a narrow neck-mold, and this is considered important. The locking of the neck-mold sections hy the raising of the body of the pressmold is an advantageous feature, as also is the removal of the press-mold, whichis entire, from the partially-formed article and simultaneous lifting of the plunger, whereby the article isfree to be carried by the neckmold in a horizontal line. The combination including the pressmold lifting-cams, so formed as to push up the mold-lifting pistons to a suitable height and then support the pistons and their corresponding press-molds in a state of rest while the plunger opens the metal thus forced up into the neck-mold, is especially important.
The simplicity and certainty of the neck- `moldclosing devices and also of the blowmold-closing devices are characteristic of the improvement, also the upward pressure of the various sectional molds against fixed parts of the machine, whereby special locking devices for the sections are rendered unnecessary, aiid also the four-post construction combined with suitable cross-bars,\vhere by both the press and blow molds are supported and operated in close proximity without a rotating table. It is obviously incidental to the latter feature of construction that any number of molds may be used by simply lengthening the table and multiplying the devices. It is further obvious that the machine is adapted,with suitable modification of the neck-molds, for the manufacture of wide-mouth vessels.
Having described our invention, what we claim is- 1. The combination of a press-mold, a cam IOO IIO
lfor elevating said mold, the cam being formed with a part concentric with its axis to hold the mold at rest in an operative position, a vertically-movable plunger and means to depress the plunger while the mold is at rest.
2. The combination of a press-mold, a neckmold, a plunger, and means for moving the press-mold to the neck-mold to partially form the neck of the article and subsequent-ly moving the plunger to the neck-mold and pressmold to initially form the interior of the article.
' 3. The combination of a press-mold, a neckmold, a plunger, a cam for moving the pressmold to the neck-mold, and means for subsequently depressing the plunger to the neckmold and press-mold, said cam and plungeroperating mechanism being controlled and operated by a single lever.
4. In combination, a press-mold, and a neckmold adapted for coperation therewith, said neck mold having depending extensions adapted to embrace the article below the neck, whereby the article is rigidly supported when suspended solely from the neck-mold.
5. The combination of a neck-mold carrying the partially-formed article, a finishingmold, means for elevating said finishing-mold to embrace the partially-formed article, and blowing apparatus automatically set in operation by the elevation of the finishing-mold.
6. The combination of a neck-mold carrying the partially-formed article, a iinishingmold, means for elevating said finishing-mold to embrace the partially-formed article, and blowing apparatus automatically set in operation by the elevation of the iinishing-mold,
and automatically shut olf in the lowering of the finishing-mold.
7. The combination of a neck-mold carrying the partially-formed article, a finishingmold, means for elevating said iinishing-mold to embrace the partially-formed article, and suitable blowing apparatus, automatically controlled by the operation of the finishingmold.
8. The combination of a press-mold, a sectional neck-mold, a plunger, and means for moving the press-mold to the neck-mold to lock the sections of the neck-mold together and partially form the neck of the article, and subsequently moving the plunger to the neck-mold and press-mold to initially form the interior of the article.
9. In combination, a press-mold, a neckmold adapted for cooperation therewith, said neck mold having depending extensions adapted to embrace the article below the neck, and means for elevatingthe press-mold to embrace the neck-mold extensions, said pressmold being chamfered to insure registry with said extensions.
In testimony whereof we have signed this specification in the presence of the subscribing witnesses.
