APPARATUS FOR FEEDING MCLTEN GLASS.

Application filed February 19, 1920. Serial No. 359,958.

To all whom it may concern:

Be it known that I, KARL E. PEILER, residing at West Hartford, in the county of Hartford and State of Connecticut, a citizen of the United States, have invented or discovered certain new and useful Improvements in Apparatus for Feeding Molten Glass, of which improvements the following is specification.

The invention described herein relates to means to be employed for changing the direction of movement of the gobs, gathers, or mold char es of glass as they pass from their point of Formation and direct the gobs or gathers centrally into the molds.

The invention described herein relates to the form or construction of a deflector capable of being easily and accurately constructed and also having its parts relatively ad-.

justable to compensate for any inaccuracies of construction. It is also an object of the invention to so construct the deflector that there will not be an liability of its becoming clogged by a defiirmation of the gobsor gathers and it is a further object of the invention to provide for formation of a lubricating film between the gobs or gathers and the guiding surfaces, thereby minimizing retardation and deformation of the gobs. The

invention is hereinafter more fully described and claimed. I V

In the accompanying drawings formlnga part of this specification, Fig. 1 is a side ele vation showing the improved deflector supported in position above a mold carried by a table and also a portion of a trough for bs from the furnace toward the deflector; Flg. 2 is a sectional elevation of the deflector and mold Fig. 3 is a top plan view of the deflector; Fig. 4 is a view partly in elevation and partly in-section showing a modification of the form shown in Fig. 1; Fig. 5 is a sectional plan view on a plane indicated by the line V-V, Fig. 1; and'Fig. 6 is a similar 'fi iew on a plane indicated by the'line VI-VI;

I n the practice of the invention the main deflecting portion 1 of my improvement has its inner or guiding surface carved longitudinally and transversely. This deflector is arranged in such relation to the conducting trough or member 2 which has such an inclination that the gathers or gobs will slide freely and quickly thereal lg and acquire sufficient momentum to carry them a substantial distance beyond the end of the conducting trough or member, as to intercept the gathers or gobs in their trajectoral movement and deflecting therefrom will direct them towards the mold. ,It is preferred that the longitudinal curvature of the deflecting portion should have such a length that when this curved trough-like structure is placed inoperative position the guiding surally decreasing radii until at its lower, end

the radius of its curvature will be approximately half the diameter of the "mold opening. As it is preferred that the deflecting portion should be made separable from the lower or guiding portion, the lower end of the deflecting portion is provided with a flange 3 whereby it may be secured on the upper end of the portion 4, which has an internal diameter approximately equal to twice the radius of the curvature at the lower end of the deflecting portion. In lieu of making the lower end or iding portion 4 cylindrical as shown in F lgs. 1, 2 and 5, it may be 'U-shaped as shown at 4 in Figs. 4 and 6. It will be readily understood that by making .the deflecting portion separable from the guiding portion, the shapin and finishing of each of the parts is great y facilitated. In addition to making the deflecting portion separable from the art 4, or

4, it is preferred that the deflecting part 1 i should be adjustably mounted on the part 4.

To this end one of the parts, as 4, may be provided with a radial ro'ove 5 for the re- Ice ception ofthe pin 6 on t e flange 3, and the parts are held'together' by cap screws 7 pass part 1 may be shifted radially of the part 4 and if the slots be made somewhat wider than the shanks of the screws as shown in Fig. 3 the deflecting part may be shifted angularly to compensate for any variation or defects in. the transverse curvature of the deflecting part 1. Incases where no lateral adjustment of the deflector on the part 4 is desired, a rib 6 may be substituted for the pin 6, as shown in Figs. 4 and 5, and if desired both pin and rib may be omitted and the deflector held in position on the part 4 solely by the screws 7 as indicated in Fig. 5.

At the upper or receiving end the deflector is provided with suitable means as a sight feed oil cup 9 to supply oil or other suitable lubricant to a passage 10 extending to and through the guiding surface. From this passage from which may radiate distributing grooves, the lubricant will flow onto and be distributed in a thin film upon the deflecting surface. This lubricating film minimizes friction and allows the gobs to slide smoothly along the deflectingsurface with little retardation. mushrooming or spreading of the front end of the gobs as they are deflected and makes uniform delivery more certain.

The combined deflector and guide are supported by an .arm 11 secured tothe shaft 10 of the pressing or blowing machine of which the table 13 carrying the molds 14 forms a part. In the arrangement shown herein the combined deflector and guide is supported with its upper or receiving end in such position relative to the delivery or directing trough 2, that the ob will pass below the upper end of the eflector, striking the deflecting surface at a very acute angle and be gradually and progressively turned from a horizontal to a vertical position in which position it will pass through the guiding portion 4 into the mold. It has been found that the momentum acquired by the gobs is suflicient to cause them to follow and remain in contact with the deflecting surface until they have been turned to a vertical position when they will drop into the molds. In order to prevent any material retardation of the gobs by impact with the deflecting surface, the upper portion of the latter is so constructed and is so supported relative to the directing trough 2 that the entering surface of the deflector is nearly parallel with -the line of movement of the gobs as they pass into the deflector, and hence as the gobs contact with such surface at a very This tends to prevent acute angle, there is practically no liability of any mushrooming or spreading of the front end of the gobs. If for any reason a gob should clog the deflector or the mouth of the mold, it can be reached by a h ook through the open side of the deflector and quickly removed.

I claim herein as my invention:

1. In apparatus for delivering gathers of molten glass, the combination with a shaping mold, of a deflector in the form of an inverted trough positioned to receive the gather tangentially and of such longitudinal curvature that the gather is gradually deflected from its original path and follows the curved trough without deformation into the mold 2. In apparatus for delivering gathers of molten glass, the combination with a shaping mold, of a longitudinally curved deflector, open on its inner curved side and positioned to receive the gather on its open side and tangentially to the curve thereof, whereby the gather is gradually deflected into the mold by the said curved open side of the deflector.

3. In apparatus for delivering gathers of molten glass, the combination with a shaping mold for the gathers, of a deflector hav ing a longitudinally curved guiding surface substantially semi-circular in dross section and open on the inside of the curve when in operative position to receive and deflect the gathers into the mold.

4. -A deflector for directing gathers of molten glass to a mold, comprising a body having a longitudinally extending curved deflecting surface substantially semi-circular in cross section, and having apassage for delivering a lubricant, through the body to the curved surface.

' 5. In apparatus for delivering gathers of molten glass, the combination of a deflector having a curved guiding surface arranged to receive the gather in a substantially tan-' gential relation to the curved surface, a guide through which the gather is discharged from the deflector, and means for supplying lubricant to the guiding surface. In testimony whereof, I have hereunto set my hand.

KARL E. PEILER.
