Briey, the invention utilizes a chuck for gripping the moil and a holder for holding the ware in axial alignment with a burner. At the start of the operation, the glassware with moil attached is placed in the holder. The burner then moves vertically with its annular :llame against the walls of the glass serving as a means to polish the glass. The continued vertical movement of the unit causes the ware holder to be picked up and moved vertically along with the burner so as to bring the moil into engagement with the moil gripping chuck. At the same time, suction is applied to the base of the ware by the holder. The jaws of the chuck grip the moil and together with the holder cause the relative rotation Vbetween the glassware and xed annular flame.

A cam control mechanism holds the burner and the ware holder units at a xed elevation for a principal glass wall softening period and iinmediately thereafter, the ware is lowered away from the moil a predetermined distance/'and the softened wall of the glass is stretched. The severance of the moil of the ware is completed by continued application of the flame at the The ware and burner then begin to descend during which time the application of ame at the severed edge with rotation of the .ware results in the formation of the suction on the base thereof is released and then as soon as the burner con-ipletesl its descent or at any other portion of the travel of the burner as may be desired, the oxygen 'supply of the Vvfiance is stopped and the temperature of thefflafn dropped. This results in the iinished 'article being elevated above the burnerwiththef-suctioni.s

removed ready to be replaced by another piece of glassware for a repeated cycle of operation." l

Referring invdetail to the drawing, the apparai,

tus consists of a `moil Vgripping chuck unit 2, a burnerv 4,y and a ware'holder unit 6, all of which 'are'in axial alignment when positioned-for severance-'of the moil from the ware. However, for the disposal of the moll, the chuck unit swings out ofthe axial alignment as shown in Figure 3.

The burner' 4, which is of conventional type, is

Vsupplied through injector 8 which connects through globe valve l0 toa gas'line I2 and through globe valve i4 to an oxygen supply line i6.

The burner 4 is supported upon bracket iB which is mounted uponthe-slide 20, which, in turn, is

carried by the rectangular slideway 22 for vertical r'eciprocati'on. A second bracket 24 is also mounted upon 'theslide 2U,`this latter bracket 24 serving 'to raise and lower the ware holder as will be described more fully hereinafter.

The lbrackets' |78V and 24 constitute angular extensions of a' plate member 28 which has slots 28 through which bolts 3l) extend for fastening the@ plate 26 to the rear portion 32 of the slide 2B.

At the base of the slide 20, there is a. lug 34 which carries-anfadju'stment screw 35. The ad- 1 ust'ment screw 3-Sfperm`its fthe -plate 2B and the integral brackets -l'S-and 24 to be raised or lowered by sliding the plate 26 entire-bolts 3S', so as to adjust the position of the burner and holder relative to the moil gripping lchuck during the severin'g operation andvthusfpermit the accommodation of glass articles of different size.

The slide lis provided with extensions 38 and which carryl rollers 4. These rollers 4B rest upon levers `42 which are pivoted at the fulcrum end 44 on the brace' 4d by means of pin 48. Between the free end 4|' `and the fulcr'um end 44 of the lever 42, there is positioned by means of a pin 50, and between the two separate levers, a roller 52. This roller 52 rides upon a cam 54 and thus, serves to raise and lower the slide 2t Vthrough movement of the lever 42 by the cam 54.

The ware holder 6 consists of ring centered bottom plate 55.V having perforations 58 about which is placed a ring of asbestos 60. TheV plate 56 is attached by vapor-tight connection to the tubular shaft 62. This shaft passes through an opening 64 in the bracket 24 and slides in a bearing 65, carried by the bracket 24. The upper portion of the shaft 62 is supplied with threads 68 which serve to position the yadjustment nut lll.V Adjustment of the distance between the holder 6 and the burner '4, when the burner and holder are both in their uppermost position, so as to accommodate glass articleszofivariouslsizes is accomplished by running Athe hut 'l0 up or down dthe threads 58 the required distance to properly position the burner 4 relative to the ware.

The lower part of the shaft 62 passes through a bearing 'l2 which is attached to the base 'I4 of the apparatus. At the lower end of the bearing T2 there is a gear 'i6 which is keyed to the shaft 62 and serves to rotate the lshaft 62 and the vholderf. The key way T8 in the shaft B2 extends" throughout its length so'that the shaft may slide lengthwise in the bearing 'l2 and the gear 1E while being rotated.

Y l The gear 15 is held in place against the bottom of the bearing 'l2 by plate 8|)y which is positioned 'upon thev base 'i4 `by the spacers 82. The plate Sii `'alsofsurlip'orts idler lgears 84 and 86, as well as the 'ame'quality control unit 88.

Atlthe lower-:end of the shaft $2 there is a suction control valve QQ. This valve 5l), the details 'of 'which are shown in Figure 6, consists of a chamber 92 having opposed seating surfaces 94 and 96 and-'a hole-98 leading into the chamber. The shaft 62- extends into thechamber 92 through the hole 98 and there'is provided on the shft 62 within the chamber an annular collar lill). This collar has seating surfaces H32 and 104 which match'withthe seating surfaces 84 and 96 respectively of the chamber 92. The lower edge of the annular collar lllil is provided `with vent ports The chamber 92 is formed in an extension |08 that is connected by means of threads IIB upon a tubular shaft H2 which is axially aligned with the shaft 52. lThe shaft H2 is, in turn, slidably carriedin a bushing .H4 which is held by means of bracket HB extending from a portion of the base 14. Theopposite end of the bracket H6 is provided with slots l IlY which permit the bracket to be adjusted to different vertical heights. The lower end of the shaft H2 is connected through elbow H3 to a flexible tube |20, which, in turn, connects to the vacuum connection 122 upon the pump |24. l f

v'The operationofthe-holder 6, shaft 62, suction control means Sil and-associated parts may be briey described as follows: As seen in Figure; l, atthe-beginning of an operation, the slide 20 will be lowered-by means of. the lever 42 to such an extent that the bracket 24 and Ibearing G6 are disengaged from'the adjustment nut lil and the burner 4 is near to the holder 6 which is held in an elevated position from the bracket 24, because the annular coll-ar l on thershaft 62'rests upon the seatingl surface which, Vin turn, rests upon the bracket l lt.- As the slide 2E! is raised by the lever 42 through operation of theA cam 54, the burner 4 and bracket 24 will correspondingly be raised and the hot annular flame will travel up vthe side of the ware 428. When the slide 20 had risen suiciently sov that the upper surface of the bearing 66 on the bracket 24 contacts the adjustment nut 10, the holder 5 -and the attached shaft 52 will be raised simultaneously with the slide 28 and the burner 4, so that throughout the remainder ofthe upward ascent of the slide the relative position yof, the lburner 4, holder 6 and ware {28 will remain the same. Y Y

As soon as4 the shaft 62 is raised, the annular collar |00 will be separated from the seat 96 and then a short distance further of travel will cause "the seat |32 to contact seat 94'. As soon as this Icontact of seats 94 and l02 results, the bleeding of air from theatmosphere through the hole 98 into the chamber 92Y and through the radial ports H16 into the tubular 'shaft H2 will be stopped and "a""suctio'n on the 'ba-secr the ware 128 will result nected and the suction will be released by the bleeding of air through hole 98 as described above. Further descent of the slide will cause the collar |00 to seat upon surface 66 and prevent Vfurther descent of the holder 6, so that the burner 4 will then travel down the sides of the ware until the further descent o-f the slide 20 is stopped by the cam 54. Throughout this entire operation, the shaft 62 and, in turn, holder 6 and Ware |28 are rotated by means of gear 16 and associated gears.

Rotation of the drive shaft |18 is accomplished through spiral gear 206 which meshes with spiral gear 204 fastened upon the shaft. In turn, gear 206 is attached on the output shaft 208 of the transmission 2|0, which is driven by motor 2|2 through pulley 2 I4, belt 2 I6 and pulley 2 |8, which is attached to the input shaft of the transmission 220. The arrangements of these pulleys and motor can best be seen in vFigure 2, whereas the arrangement of transmission and gears for the driveshaft can best be seen in Figure '7. At the opposite end of shaft 220 there is attached pump i 24 which furnishes the vacuum for provision of suction as described above.

Figures 7 and 9 further shoW the arrangement of the cam 54 and gear shafts associated with the transmission 2|0. Thus, the cam 54 which is attached to shaft 208 consists of a plate 222 fastened to a bushing 224 which is keyed to the shaft 208. The plate 222 is provided with a series of holes 226 through which bolts 228 may be extended for fastening adjustment patches 230 to the plate 222. These adjustment patches 230 have over-size holes 232 for receiving the bolts '228, so that the lpatches may be adjusted as to position relative to the plate 222 with the result that a variation in the contour in the cam 54 may be obtained in order to vary the different steps in the cycle of operation of this invention, as will be more fully described hereinafter in relation to Figure 10.

As indicated above, the cam 54 controls the levers 42 and the roller 52 which rides upon the cam 54 and is carried between the levers by the lpin 50. In addition, the cam 54 controls the action of the flame quality control means 88. This latter control is accomplished by the raising and lowering of the rod 234 by means of the clevis 236 which extends over the pin 50.

The details of the flame quality control unit 88 are shown in Figure 8. Thus, at the end of the rod 234, there is threaded a valve plug 238 provided with

radial holes

240 and 242 and longitudinal hole 246. The plug 238 rides in fiuidtight bearings 248 and 250 which are contained in the chamber 252 of the valve housing 254. The' housing 254 which is attached by means of bolts 256 to the base 14 alsol carries bearing 258 through which the plug 238 moves. A second chamber 260 is superposed above the chamber 252 and separated therefrom by means of the bearing 250. An inlet tube 262 which is connected by flexible elbow 264 to oxygen supply line 266 enters the chamber 252. The chamber 260 is provided with oxygen outlet line 268 to which is attached the flexible oxygen tube |6. The control means 88 is completed by means of an oil shield 218 which is retained between the end of the rod 234 and the end of the plug 246. This shield 210 performs the dual purpose of limiting the descent of the plug 38 and also prevents oil or othervcombustible matter from flowing past the bearing 258 into the

chambers

252 and 266.

As can be seen by comparison of Figure 5 and Figure 8 when the plug '238 is raised through the action of the cam 54 so that hole 242 is above bearing 250, oxygen will flow from line 266 through control means 88 and line i6 into the burner 4. On the other hand, when the plug is lowered by the action of the cam 54 so that hole 242 is below the bearing 250, the supply of oxygen to line |6 will be cut off. Adjustment can be made by the clevis 236 so that the oxygen supply to the burner 4 will be cut off by unit 88 during any desired portion of ascent and descent of the burner during the steps in the cycle of operation.

piece of glassware.

`Returning for consideration ofthe chuck unit 2, it will be seen that the gear |58 carries two cams 212 fand 214 which are located on opposite sides of the gear |58 vfrom one another. Cam 212 is positioned upon the gear |58 so as to intermittently engage roller |14 on lever |64 as the gear rotates and to thus actuate the jaws |38 of the chuck, so asV to grip or release the moil.

The cam 214 is responsible for swinging chuck unit 2 for disposal of the moil. Thus,`the cam 214 is located so vas to intermittently engage roller 216 which is located upon semi-circular lever 218. This lever 218 is fulcrumed on rectangular `post 28B attached to arm |98. The opposite end of the lever 218 is provided with slot 282 which slidably engages pin 284 carried by the base |35.

In operation, the gear |58 rotates and carries with it cam 214. At the proper portion of the cycle of operation the roller 216 contacts the cam 214 and in so doing, forces the movable end or the lever 218 against the pin 284, thus causing the base |30 to swing as indicated in Figures 3 and 4, for the disposal of the moil. rotation of the gear |58 carries the roller 216 beyond the peak of the cam 214 and permits the base |30 to be drawn back by the action of the spring |86 into position for receival of another The extent of back swing of the base |30 is governed by stop plate 286, the position of which can be adjusted -by means of set screw 288 threaded through post 286.

The cam 212 is so positioned relative to the cam 214 so that when the unit 2 has been swung to the side, as shown in Figure 3, the roller |14 will engage cam 212 causing the jaws |36 to open and drop the severed moil 290 down the pipe 292 to a cullet receiver (not shown) The entire chuck unit 2 is provided with a removable cover 294 which is held on the unit by brace 296.

The various steps in the cycle of operation can be explained with reference to Figure l of the drawing. This iigure shows the various steps of operation in relationship to the portion of the control cam 54 to which they relate. Thus, the cycle of operation comprises a. loading and unloading step A, a nre polishing step B, a wall softening step C, a stretching step D, a severing step E and a beading step F and a polishing and .annealing step G. AS explained above, the relative period of time during which each of these ,steps is in progress may be varied by means of adjustment of the patches 238 upon hte plate 222.

The operation of the apparatus during the entire cycle may be comprehended by reference to Figure l0 and Figure l.

At the beginning of the operation, i. e., the loading step, the roller 52 rides upon the portion A of the cam so that the holder 6 and slide are in the position shown in solid in Figure l. The ware with moil attached is positioned in the holder 6. As the cam 54 revolves, the roller contacts the nre polishing or B portion of the cam so that the slide 29 is raised uniformly with the result that the burner 4 travels upwardly relative to the ware, impinging an annular flame upon the sides of the ware, since during this step of operation the holder 6 and ware |28 do not move vertically, but merely rotate. Within this period of time the bracket 24 has been raised sufiiciently so that the bearing 86 has contacted the adjustment nut 16 and the shaft 62 together with holder 6 and ware |28 has been raised along with the burner 4. At the same time, atmospheric Further bleeding of the suction valve 9i) has been stopped in the fashion described above so 'that the vware is firmly held in the holder 6 by means of the applied suction through the perforations 58 'in the plate 56. During the same period of time, the chuck unit 2 has been swung into the .position shown vin dotted section in Figure l and the jaws |38 have been clamped over the moil.Y

As the cam continues further rotation, the roller 52 contacts the wall softening or C Vportion of the cam. During this period, the glass is rotated within the annular iame without vertical movement, so that the glass at the junction of the moil and ware becomes soft.

Further rotation of the cam brings into play the stretching portion D, with the result that the slide 20, burner 4 and holder 6, together with the ware |28, are drawn down a short distance away from the moil, which is retained against vertical movement by the jaws |38. rIhere after, the severing portion E of the cam operates to cause the flame to completely burn through the stretched section of the glass. Then the beading section Foi the cam operates so that the burner proceeds downwardly with the ware forming a bead upon the severed edge of the ware. Finally, the polishing and annealing section G causes further lowering of the slide so that the bearing 66 disengages from the adjustment nut 10 and the burner proceeds dow-n the ware to the unloading position, as shown in solid section in Figure l. At the same time, the position of the plug 238 in the control unit 38 has been adjusted through the action of cam 54 and rod 234 so that the oxygen supply to the burner has been discontinued. The completely severed, polished and annealed ware is then removed from the holder, from which the suction has been by this time discontinued, and a new piece of glassware inserted for a repetition of the nishing operation.
