July 10, 1923- R. F. HALL MACHINE FOR THE MANUFACTURE OF GLASS ARTICLES Filed July 27, 1920 nu 4 rd,
of the position or movement of the swinging Application filed m 27, 1920. Serial 116. access.
To aZZ'whom it may concern: I v
Be it known that I RoBnR'r Fnnnnmox HALL,'a subi'ect of the king ofGreat Britain and Ire and, residing at Moseley, near Birmingham, in the county of Warwick, England, have" invented certain new and useful Improvements in Machmes for the Manufacture of Glass Articles (for which I have filed an -application in Great Britain, No. 8769, filed Jan. 21, 1918), of which the following is a specification.
This invention relates to rotary machines for the manufacture of glass articles,and refers to that type of such machines 1n which the molten glass, from which the articles are to be formed, is drawn by means of suction into aparison or other mold, the said mold being open at the bottom and being lowered to the surface of the molten glass, toenable-theglass to be drawn into the interior thereof, after which the mold is raised and the parison therein contained is enclosed in a finishing mold and carried 7 through the various operations for the production of the finished article.
It has already been proposed to mount the finishing or blowing molds in 001118.60 tion with a main rotatable framework so that, theyare adapted to swing upwards, and to raise them at appropriate times by means of rack and pinion caring or by means of a roller attache beneath the swim 'ng framework and running upon a suite 1e camway.
My present invention has for one of its principal objects to provide improved means for carryi, raising and lowe the finishing mol and associated parts.
A further object of the intention is to provide improved means fonopenmg and closing the mold, so that such opening and closing may be readily efiected irrespective frames or the like carrying the molds.
Other objects of the invention will also be referred to in the specification asregards minor constructional. details and arrange ments. r
In the general way. of carrying out my invention, each finish a "moldis carried by a pivoted frame or member, constituting a lever of the first order, adapted to SW11! about a horizontal axisyi's counterbalanced parts in an elongated loop or it p annulus 15, ,and is adapted to be raised and lowered at v ph p ate times by means of acam or an electric solenoid or by fluid pressure or by acombination of any or all of these means.
The opening and closing of the halves of the mol are operated by a lever or levers or the like independently-of the movements e frame or member carry-- or position of t ing the molds. t 4
This openin and closing ma by toggle mec anism operated be efiected by a lever pivoted to the 'swin 'ng frame, the said lever being operated t rough suitable mechanism, from a cam in connection with the fixed framework of the machine.
I prefer to mount the mechanism carrying the finishing mold and its associated uivalent, adapted to be. easily laced in position so as to orm an integra portion of the main framework, and easily removed from'such framework to facilitate the building and repair of the machine. a
In order that my invention may be more clearl understood 1 will now proceed to descri e the same with reference to the accompanying drawing which shows more or less diagrammatically a part sectional eleva= tion of the mechanism for operati and controlling the finishing mold of one unit of a bottle maki m" a ne of the general type more particiil arlv described in In so pending application l lo. 399,427, filed July 27, 1920. L
The numerals of reference in the tollowing description correspond as far as pible with those used in connection with the draw ings accompanying my said co-pending appllcation. Y
1 indicates one of the supporti wheels, adapted to run un rails 2, in t neighborhood of the rnace, in the ordinary manner. v v
The wheels snort the main lower Era-- work ofthe ma 1 which is comd of longitudinally disposed girders f2 connected by transverm rders &
The 'rdcr ramework 7, 8 carries a ring 11, which in turn carries a channeled lit-d 12, forming the lower member of a fit bearing. 14 is another ring to i l-1mg the n per member of the ball bearing, and to this latter Ping-i8 attached an internall r Suitably supported upon e lows 'vertical struts 19, carried by brackets 20 from the column 16. '24 is another cam carried by suitable brackets on the fixed framework of the machine.
Bolted between a rotatable member at the top of the machine and the annulus 15 is a column or framework 96 hereinafter called the bifurcatedcolumn, a column of this description being provided for each bottle making unit.
Each column 1S formed from castings of H section at the lower part and solid up to the height of the trunnions 31, from which position to the top they are hollow, so that air may be passed down from the air reservoir to the top of the machne to the trunnions 31.
The upper part of the bifurcated column -may carry the parison mold and its associated mechanisms which need not be described in detall, in the present specification as they! form the subject of a co-pending application.
As already explained, each of the bifur-- cated columns is formed at 31 with hearings in which work the trunnions of the lever or frame carrying the finishing mold and its associated parts.
This consists of a casting 300 formed with a suitable passage for air in connection with the hollow passages in the sides of the bifurcatedcolumn through the trunnions and bearings 31.
The casting 300 with the extension arm 300 on the other side of the trunnion31 constitutes a lever of the first order.
301 is a counterbalance weight, which is preferably somewhat heavier than the finish ing mold and associated parts, so that the said mold tends normally to remain in the raised position.
The weight 301 is adapted to slide vertically upon a guide 302 connected by means of a horizontal stay 303 to the bifurcated column above the trunnions 31.
At the lower end the vertical guide 302 is of T shape and is connected. by two horizontal stays 304: to the base 305 of the bifurcated column 96.
It will thus be seen that the weight 301 can slide vertically upon the guide 302, which passes therethrough.
The arm 300 IS bifurcated, one of the arms of the fork coming on each side of the weight. Each arm is provided with a roller 306, and each of these rollers is adapted to work in a horizontal slot 307 on the outside of the weight 301 so that as the weight rises and tells, it raises and lowers the frame 300 by turning it about its fulcrum 31.
The raising and lowering of the weight the arm 49 from the pivot 53) behind one half M of the finishing mold.
The opening and closing of the finishing mold is effected in the following manner.
Each of the arms carrying one half M of the mold is extended backwards beyond the bearing and the ends of the arms are connected to linking rods which are in turn connected to a slide block 122, a helical compression spring surrounding each of the rods.
The block 122 is connected to an S shaped lever 123, pivoted at 124 to the swinging framework 300. The S shaped lever 123 is connected at 125 to a link 126, which is pivoted at, 127 to one arm of a bell crank lever pivotally mounted at 128 in a recess within the weight 301.
The other arm of this bell crank lever is pivoted at 308 to a vertical rod 309 which is operated from rollers 310 in connection with the cam 17 It will be seen that the cam 17' may be so proportioned and arran ed that the opening and closing of the finlshing mold can be eii'ected to suit requirements independently of the position of the mold. In practice it Where the rise of the mold is brought about solely by means of a cam as is usually the case with rotary machines tor the manufacture of bottles or the like, there is considerable friction and a large amount of work has to be expended in order to elict the raising, and in any case the use of steep cams to effect a raising operation is to be deprecated.
The counterbalance weight which it is to be remembered tends normally to keep the blowing mold pressed securely in t e correct position relatively to the neck mo d causes very little work to be expended in the operation of the raising of the mold, since the cam rollers in connection with the weight simply run down a steep slope on the cam. On the other hand, the slope which raises the weight and depresses the mold may be of comparatively moderate gradient and ii the amount of weight on each side of the fulcrum is nearly equal, the operation of lowering the mold. by raising the weight also causes very little work to be expended.
in some cases the raising and lowering of the finishin mold may be effected by means of an electric solenoid or by means of a fluid pressure motor, working alone or in combination with suitable cams.
Examples of raising and lowering the counterbalance weight of the finishing molds by means of an electric solenoid or by'a fluid pressure motor being l\given in my co-pendmg application Ser. 0. 399,430, filed July 27, 1920, it is not thought necessary to illustrate these methods in detail in connection with the present specification.
- It is to be pointed out that in the preferred construction the lever carrying the finishing mold is mounted in an elongated loop or its equivalent more fully described in the specification of my said co-pending applicatlon, which can be easily removed from the rotatable framework of the machine by unbolting it from the rotatable ring at the bottom and from the arm or the like at the top; or in some cases both the arm and the elongated loop or its equivalent may be detached as a whole. It is also preferable to mount the parison mold and its associated parts in the same elongated loop at a higher level, so that the arison and finishing molds of any unit can be removed as a whole and the unit can be quickly replaced by a fresh one in case of accidents without stopping the machine for any considerable time. As an alternative the unit may be removed altogether and the machine can be worked without the said unit.
It will be understood that the particular details of construction may be varied without departing from the principle of my invention.
