DETAILED DESCRIPTION OF THE DRAWINGS
2With particular reference to Fig. 1, the orifice ring and holder of the invention will be described in the ~ environment of its use. AS shown in Fig. 1, a feeder G bowl 10, formed of ceramic material, has the usual tube 11 ~ positioned therein concentric with the lower feeder orifice, 7 designated 12. The tube 11, in cooperation with the inner 8 ledge of the feeder 10, will determine the quantity of glass entering into the area of the feeder orifice 12.
Also within the area of the feeder orifice, and within the 11 confines of the rotating tube 11, are positioned four 12 vertical plungers 13. In the operation of the feeder 10, 18 the plungers 13 are reciprocated in timed sequence, with ~ all being reciprocated together as a unit under normal 16 operating conditions. The orifice 12 is closed by a 18 ceramic orifice ring, generally designated 14. The orifice tq ring 14 will be described in greater detail with reference 18 to Figs. 4-7. The orifice ring 14 is supported in a 19 holder or pan 15.
The holder 15 will be described in somewhat greater 21 detail with reference to Figs. 2 and 3. Suffice it to 2~ say, the holder 15 is a generally cylindrical metal pan 28 having a planar bottom surface with the orifice ring 14 supported by the holder in its operative position as shown 26 in Fig. 1. The pan 15 is supported and held in the 26 operative position by a metal ring-like member 16, which 27 extends about and embraces the pan 15 with the pan resting 28 on an upper ledge 17 of the support ring 16. The feeder 2~ 10, which is ceramic and has a bowl-like configuration, is supported in the position shown by a metal frame 18, Form 233 ~2;~75SO
1 only a portion of which is shown in Fig. 1. This frame 18 2 has an opening, as shown in Fig. 1, which is somewhat 8 larger than the orifice 12 in the feeder bowl 10. The holder or pan 15 and the ring 14extend through the 6 opening in the frame 18 beneath the feeder bowl 10. The 6 ceramic orifice ring 14 carried by the pan 15 is held 7 against the lower surface of the feeder bowl and a sealing 8 material 19 is interposed between the upper surface of the ~ orifice ring and the lower surface of the feeder bowl 10.
lo In the past this sealing material 19 took the form of an 11 asbestos rope; however, presently the material is of a 12 non asbestos composition capable of withstanding high 18 temperature without becoming distorted, and thereby prevents ~ leakage of glass through any opening that might otherwise 16 appear between the orifice ring 14 and the lower surface of 1~ the feeder bowl.
Iq The metal ring 16 is pivotally mounted at 20 to a 18 fixed pivot pin 21. Diametrically opposite to the pin 21, 1~ the ring 16 has a downwardly extending boss portion 22 that is engaged by a clamp lever 23 which pivots about a 21 shaft 24. The lever 23 is locked in its engaging position, 22 as shown in Fig. 1, by a suitable operating mechanism (not 28 shown). The pan 15, as best shown in Fig. 2 at the left 2~ side thereof, is provided with an outwardly extending, 26 bifurcated flat plate or tongue 25. This plate 25 engages 26 with a vertical pin 26 carried by the ring 16~ thus 27 accurately locating the pan 15 in the ring 16.
28 Turning now to Figs. 2 and 3, it can be seen that the 2g pan 15 is generally comprised of a cylindrical wall 27 having an inwardly stepped portion 28, this stepped portion 28 Porm 233 ~237~5~30 15 714 VSA
1 being the area which fits within the ring 16 and is 2 supported by the ledge 17 of the support ring 16. The bottom of the pan 15 is a generally horizontally extending flat member 29 having a planar upper surface 30. An 6 elongated opening 31 extends nearly the full diameter of the bottom 29 of the pan 15 and runs generally in the 7 direction of the plate 25. This opening 31 is to accommodate 8 the four feeder orifices found in the orifice ring. The 9 opening 31,intermediate the length of its two parallel sides 32, is provided with a pair of ring locating slots 33.
11 As best shown in Fig. 2, the slots 33 are generally 12 rectangular and extend radially outwardly with respect to lJ the central axis of the pan 15.
~ Turning now to Figs. 4-7, the orifice ring itself will 16 be described in detail, and the manner of its mounting in lB the orifice ring holder or pan 15 will also be described.
t7 The ring 14 is made of a ceramic material and is normally 18 cast in a mold when being made and fired to set the material 19 into a precise shape. It should be pointed out that it is extremely important that the orifice ring seat within the 21 pan 80 that its upper surface, which is to be sealed 22 against the lower surface of the feeder bowl, will be 28 parallel to the bottom of the orifice pan 15 when they 8~ are assembled. In order to assure that this occurs, and also 26 that the ring 14 is precisely and accurately positioned 26 centerwise of the pan 15, the orifice ring 14 is formed 27 with a pair of locating keys 34 in the bottom surface 28 thereof. The keys 34 are intended, upon assembly with the 29 pan 15, to be located within the ring-locating slots 33.
~o In addition to the keys 34, the orifice ring 14 is formed Porm Z33 ~.~375~0 15 714 USA
1 with four seating pads 35. The seating pads 35 extend 2 1/16 inch below the adjacent bottom surface 36 of the 8 orifice ring 14. These pads are accurately formed and the four of them, as shown in Fig. 4, are made to be 6 precisely parallel with the upper sealing surface of the ~ orifice ring. At the inside edges of the pads 35 are 7 downwardly extending vertical pads 37 which fit within 8 and are located along the sides 32 of the elongated open-0 ing 31. These side-locating pads, as seen in Fig. 4, extend outward slightly relative to the general dimension 11 of the downwardly extending areas 39, which form orifices 38.
12 Thus it can be seen that when the orifice ring 14 is 18 assembled in the orifice pan 15, the pad 35 will rest on 1~ the planar surface 30 of the bottom 29 of the pan 15.
16 Additionally, the keys 34 will be located in the ring-1~ locating slots 33 and the surfaces of the side-locating Iq pads 37 will accurately position the orifice ring within 18 the precise center of the pan 15. The four orifice openings 38 extend through the bottom of the orifice ring and are located on centers which are on a precise diameter of the 21 ring 14 and are spaced apart equidistant along this 22 diameter. Furthermore, each of the orifices 38 is to be 28 a true circle as is necessary in order to provide precise, 24 accurate feeding of molten glass where all of the mold 26 charges or gobs are of the same weight. The area between 28 the pan 15 and the orifice 14, when in their assembled 27 relationship as shown in Fig. 1, is filled with a packed 28 insulating material to provide heat insulation to the 23 ring 14 in order to obtain a uniform thermal radiation and conduction from the orifice ring 14 about its circum-81 ference.
~2 Form 233 5~30 15 714 USA
1 Thus it can be seen that an orifice ring and the 2 holder or pan for supporting the orifice ring, which has ~ four glass feeding orifices formed therein, is provided, and 4 which may be accurately positioned and held in the orifice 6 opening of a glass feeder bowl.
B While the foregoing description has been in conjunction 7 with a quadruple orifice ring and holder, it should be 8 apparent that the number of orifices in the ring could be 9 more or less than that shown without departing from the spirit and scope of the invention.
11 Furthermore, the keys 34 in the orifice ring provide 12 the mechanism for locating the orifice ring relative to the 18 pan in the direction of the centers of the orifices. Because ~ the keys 34 are of a fairly small dimension, they do not expand under heat from the glass to any appreciable extent ~ and cause the ring to crack as has been a problem in the l7 prior art arrangements. Although the small keys 34 are a 18 preferred longitudinal position locating means for the ring 19 in the pan, alternative locating means in the form of down-wardly extending surfaces at the extreme ends of the ring 21 would be capable of providing this longitudinal centering 22 function.
28 It would, however, require some care in designing the 2~ ring so that it would have sufficient clearance with the 2~ ends of the hole in the pan, that expansion of the ring on 26 heat-up with molten glass would not cause expansion to the 27 extent that the ring would break, but would accurately locate 28 the ring in the longitudinal direction of the opening in the 29 same manner as the surfaces 37 locate the ring sideways in the opening in the pan.
27 It is a further object of this invention to provide 28 an orifice ring and pan or holder combination which assures 29 the support of the ring against the bottom of the bowl with ~o uniform force and with the proper alignment.

The holder or pan 15 and the ring 14extend through the 6 opening in the frame 18 beneath the feeder bowl 10. The 6 ceramic orifice ring 14 carried by the pan 15 is held 7 against the lower surface of the feeder bowl and a sealing 8 material 19 is interposed between the upper surface of the ~ orifice ring and the lower surface of the feeder bowl 10.

This plate 25 engages 26 with a vertical pin 26 carried by the ring 16~ thus 27 accurately locating the pan 15 in the ring 16.
28 Turning now to Figs. 2 and 3, it can be seen that the 2g pan 15 is generally comprised of a cylindrical wall 27 having an inwardly stepped portion 28, this stepped portion 28 Porm 233 ~237~5~30 15 714 VSA
1 being the area which fits within the ring 16 and is 2 supported by the ledge 17 of the support ring 16.
