Definitions

  • This invention relates to such a method for operating upon a rotative glass body which employs a holder for holding the ware in a flame corona in such a way that the axis of the said holder coincides substantially with the axis of the flame corona during a relative rotation between the glassware and annular flame.
  • the flames of the coronary burner for instance, for cutting off the lost top of a chalice or for burning in the brim thereof, act as uniformly as possible along the entire circumference of the glass object and for that purpose the spacing of every point of this circumference from the burner must be as constant as possible.
  • FIGURE 1 shows, partially in a vertical section and partially in side elevation, apparatus in accordance with one embodiment of this invention.
  • FIGURE 2 is an enlarged plan View of a centering ring included in the apparatus shown in FIGURE 1.
  • FIGURE 3 shows a vertical section of a modified embodiment of a holder.
  • FIGURE 4 shows partially in side elevation and partially in axial section a centering means which is supposed to be mounted above and coaxially with a holder as shown in FIGURE 3.
  • the annular or coronary burner is generally identified by the reference numeral 1, while the assembly of the object holder and supporting table is generally identified by the reference numeral 2.
  • the glass object such as, for example, a chalice, has the lower side of its foot inserted in the saucer shaped plate 3, which forms a part of the supporting table 4.
  • a vacuum duct 5, 6, 7', 8 extends through the holder and the supporting table which forms a part thereof and opens at an aperture 9 of the table plate 3, thus providing for suspending the glass object, at its foot, by suction in the holder 2.
  • the supporting table 4 is suspended by means of three coupling rods 14 which are positioned at the corners of an isosceles triangle, and one of which is visible in FIGURE 1.
  • Each of these coupling rods is connected at its opposite ends, by means of universal joints, to the holder 13 and the table 4 respectively, as schematically indicated at the upper end of rod 14 by the crossed lines on two blocks on the 0pposite sides of this upper end.
  • the supporting table 4 is thus capable of swinging horizontally under the holder 13.
  • a coupling plate It) bearing against the foot plate 12 of the holder will follow this swinging movement as it is coupled by means of a universal join-t 11 to the table plate 3.
  • FIGURE 2 shows this ring after the cover, 15 (FIG. 1) has been removed.
  • the adjusting ring 16 which is turnable by means of the handle 17 to the angu lar extent permitted by engagement of the handle with the opposite ends of the slot 1d.
  • rollers 34, 35, 36 which contact the object, are always exactly situated on a circle, the center of which is the axis of rotation of the holder 2, and coincides with the center of the burner I the object is thus brought to a position in which the circumference engaged by rollers 34, 35 and 36 practically coincides with a circle having its center in the axis of rotation of the holder 12.
  • the bearing plate 4 follows this adjustment as it is capable of sliding together with the coupling plate 10 along the foot plate 12 of the holder 13.
  • the cock 37 in the branch duct 38 of the vacuum conduit 8, 7 (FIG. 1) is then turned to its open position so that the vacuum contact in space 39 for drawing the coupling piece 19 against the holder plate 12, whereby the supporting table 4 is also retained in the adjusted position.
  • Handle 17 can now be released so that spring 56 acts thereon to retract the rollers 34, 35 and 36 from contact with the object. Then holder 2 is raised, and centering ring 33 can be moved laterally away from its operative position above burner 1. Finally, the centered area of the object is moved into the plane of burner 1 by relative axial displacement of the burner and holder 2.
  • ball and socket joints 40 and 41 which are air-tight are provided at the opposite ends of the vacuum conduit 6 so as to permit the displacement of the table 4 relative to the holder 13 during the described centering of the object.
  • the holder 42 supports a mushroom shaped table 45 having a vacuum aperture 46.
  • the aperture 46 is communicated with a source of vacuum through a duct 47 which opens from a swingably mounted tube 62.
  • a branch duct 48 having a' cock 49 therein extends from the duct 47 to a space between the base of table 45 and an intermediate piece 44 which is slidably engaged by the table and is mounted on holder 42 by means of a' universal joint 43.
  • the supporting table 45 slides to the desired position with respect to the holder 42. (The axis of the holder 42 coincides with the axis of the burner.) 'Then the table 45 is fixed to the holder 42 by means of the vacuum acting in space 50.
  • This device of FIG. 3 is to be used with a centering ring of the kind described above with reference to FIGS. 1 and '2.
  • the spindle 53 is capable of up and down movement with respect to the sleeve 54, which surrounds the spindle, for opening and closing the clutch 51;
  • the mechanism serving that purpose is not described.
  • the'clearance between the sleeve 54 turning along with the spindle 53 and the holder 60 can be decreased to such an extent that, on lowering the clutch towards the object and on closing the fingers 52, the object is centered with respect to the holder 42, and thereafter the object isfixed relative to the holder 42 by action of vacuum in the space 50 of the latter.
  • the illustrated embodiment is, however, by reason of the relatively large clearance 55, suitable for cases, for instance in processing uniform press glass, in which the objects can be placed by hand in a centered position on an adapted holder.
  • the sleeve 54 and the spindle 53 can move laterally to a small extent by reason of the mounting of the upper end of sleeve 54 on an elastic ring 57 which is supported by the ball ring 58 of a ball bearing 59 provided in the holder 60.
  • the spindle 53 has a head 61 at its upper end which is resiliently supported on the sleeve 54.
  • the clutch spindle 53 is constrained to rotate with the holder 42 so that actuation of this spindle from above is not necessary.
  • the device according to FIGS. 3 and 4 is intended particularly for automatically manufactured articles, e.g. articles made in press moulds, which can be. manufactured with small tolerances, whereas the device according to the FIGS. 1 and 2 is also suitable for manually manufactured objects.
  • a device for treating glass bodies of revolution the combination of an-annular burner for heating a circumferentially extending region of a glass body of revolution during rotation of the latter with said circumferential region of the body located axially at a plane within said burner, a holder rotatable coaxially relative to said burner, said holder and burner being axially displaceabie relative to each other, a table for supporting a glass body to be treated, means mounting said table on said holder so as to be fixed axially with respect to the latter with the plane of said tablebeing parallel to said plane within the burner and with said table being adjustable laterally relative to said holder, means for securing a glass body of revolution to said table, centering means for the burner located in a plane spaced axially from, and parallel to said plane within said burner and engageable with a glass body secured to said table when the holder is axially disposed to axially located said circumferential region of the glass body at the plane of said centering means said centering means being operative to center
  • said table has an aperture opening at a surface thereof engageable by a glass body to be treated
  • said means for securing a glass body to said table includes means defining a vacuum duct extending through said holder and opening at said aperture of the table, and wherein said table and holder have confronting relatively slidable surfaces Which are recessed to define a space therebetween
  • said means for securing the table relative to the holder includes means defining a branch duct extending from said vacuum duct and opening in said space, and valve means interposed in said branch duct.
