Manufacturing Glass, ofwhic the following is a specification.
My invention relates generellyf to the meniro nfectnre of hollow glass articles, end more 2 5 become more pronounced cylinders increases. These waves are ofparticular-l to the manufacture of hollow glass cylin nog of window-glass though it is to be under- `1stood that I do not limit my invention to the `iproduction of any definite article which it is A ,ne able of making.
n the drawing of hollow cylindereY by methods new in use they have@ wnrnipnnlgmce, due largely to weven of weging' 'res-V fh the geeeegrsie inn: A(ly inders made by Said methods are fairly rood for about the first five feet; but below t is the cylinders are encircled hy a series of'transverse waves, whic as the height ofthe course produced by the existence of en unbalanced or unequal pressure within the cyl. inders.
It iseth provide a rcmedyor 1u other words, to equalize the pressure within the cylinders whereby they may be drawn e object of my present invention to vmore perfectly than has hitherto been possi- Other objects will appear in the description following.
In the drawings, tive of only va, few forms which my lnvention Vmay assume Figure 1 shows thc-mechanism thereof partly in elevation and' artly in vertial section, andV Fig. 2 u sir ar view of n modification thereof.
Referring to Figs. 1 und 2 of the drew'ngsf l designates vertical standards or masts on which the carriage 2 is mounted to slide veri tically. The carri e is raised and lowered by Ineens of the cab e or other flexible device which is secured at one end to the carriage 5o and at the other end to e winding-dimer other device. (Not showr l @he carri 2 supports in any approved ey the drawingers produced as' a. step in the mela the unequal pressures* which are merely illustral tool 4 in euch a manner that it can he readily detached therefrom.
5 represents a furnace supplied ing devices, 'as the burners 6. the furnace Ylies the o cui l", through w the cylindereare drn'n. nn the opcnin mount the )let 8, whioli'has-.the annuler gg ess |holding ce," ityf 9, tile cnxtrul `hoes l0 ming provided tliltl'le opening'll. The bottom of the furnace '5 is provided with a guidebloelr 12, the upperend of the same being preferably in Contact with the bottom of the pot in use.
' VNithin the tube 12 is the air-inlet pipe 13, which extends through the opening 1l in the Ypot and slightly above the boss 1G. The upper Vend Vof tube h und a second branch i7, leadn to the int'erior of the' drawing-tool 4. upwardlyopening cavity orother valve i8 is provided in ,the pipe 15, which vulve will be opened, if for any reason thepressure in the pipe l5 rises above a. definite limit, in order that the pressure transmitted to the interior of the cylinder shell notexceed the necessary ernennt. v
If preferred, the xpos 16 and 17 may be connected to separa. `sources `of pressure, es indicated 'n Fig. 2, in whichthe pipes 16 und 17 eachhesavalvel.
i9 is e-bar normally su ported by the cross-pin 20, which passes' t erethrough and rest' on the top of the horizontnlegport '21. The letter has a slot through whic the pin will ass tolgt T e opera .mn laas follows: The ot is placed as shown in Figs. 1 and 2. il olten P-g iras is pouredinto the pot end` the carriae i '2 is lowered until the drawing-tool enters t o l glass slight! After the glass adheres soilicientl to the tool the carriage 2 is elevated and au' is admitted to the interior of. the hollow cylinder, suflcient pressure being admitted t0 the Cylinder to e undA its mmtrnetcd noch:v ortion to the desir d dlimcter for tlic eylin er. Thepressure is regulated by the lector lll, which directs the incoming eir or` the bar 1 9 down upon the valve.
with lient. The top of rich 13 is provided with the de- Y lOO ` sure within the bai' 19 or in any other desired manner. The pressure within the cylinder should preferably remain substantially uniform during the subsequent drawin operation. If for any reason there shoul exist at one end of the cylinder a tendency to develop or transmit a change of density of the air within the cylinder, there woul be a oounteraetingr force at the opposite end through the branch tube leadingthereto. The two tubes 1G and 17 ten'd to equalize the pressure within the cylinder and notonly modify or nullify a change of density, but rather prevent the roductionof such echange.. The valve or va ves 1S also regulate the Vpressure of the air, as the aiizmust pass the valve before reaching the c vli der. `llA the pressure should be excessive-fili" the inlet 13, the valve will be opened anr lpermit the excess to escape. After the cylinder liasbeenforrneditfis severed from the bathin thepot and removed in any pre-` ferred manner. f
I ,do not desire to be restricted to any of the det-ails'shown and described as various means maybe ernploy'edto equalize the prestion. l
Having described my invention,-l"claim- 1. 'In an ap aratus for drawing hollow glass bodies, w ei'ein4 a gaseous pressure is i" ,supplied withiii' the body during operation, means for cqualizing the pressure throughout apparatus lfor drawing hollow glass bodies, -means for containing the glass toglie drawn, a drawing-tool arranged to draw a'` hollow body, means for supplying gaseous fluid to the interior of said body dur-y draw a hollow body, and a plurality`of ducts cylinders during their formanl for drawing hollow Iluid.
5. In anapparatus for Ydra'wing hollow glass bodies, means for containing the glass to be drawn, a drawing-tool arranged to draw a hollow body, a gaseoiis-liiidsupply ipe, and branch pipes connected thereto and ceding'l from the exterior to diilereiit longitudinal portions Iof the interior of the cylinder being formed.
