Definitions

  • a novel apparatus which, essentially, rigidifies itself with the insert or shell and mounts the vibrator within the shell so that the vibratory forces are transmitted uniformly throughout the shell, thus eliminating the need for repositioning the apparatus in the shell.
  • the apparatus is so constructed that it lends itself for use with such noncylindrical inserts as ovals, etc.
  • the apparatus includes a central part from which radiate opposing arms or members, at least one of which is outwardly movable, to engage interior portions of the shell, whereby the apparatus becomes rigidified with the shell and is thus capable of transmitting vibratory forces uniformly throughout the length and circumference of the insert and thus the apparatus need not be repositioned.
  • FIG. 1 is a elevation, partly in section, showing the mounting apparatus
  • FIG. 2 is a section, on a reduced scale, showing the FIG. 1 apparatus in use in a furnace.
  • a PREFERRED EMBODIMENT DESCRIPTION OF A PREFERRED EMBODIMENT Guides ll carry jaws or members 2 for radial sliding movement and the jaws are biased inwardly by means in the form of springs 3 acting in opposition to the effects of an upright spindie or screw 4 which is threaded into an intermediate part 5 of the guide to rotate in a central part 6 which has an under portion adapted to carry a conventional vibrator 7, which may be of the pneumatic type.
  • Cooperative cams or ramps 8 and 9 cause the jaws or members 2 to move outward when the screw 4 is turned in one direction and to retract or move inwardly when the screw is turned oppositely, because the springs 3 do the retracting.
  • the apparatus is positionable substantially centrally within an electric are or induction furnace, here having a base 10 and an outer annular refractory wall 11 about which induction winding occurs at 12 and within which is positioned the usual shell or insert, here 13.
  • the shell is of course smaller than the wall 11 and this leaves an annular space into which conventional refractory particulate material is introduced as at 14.
  • the central part 6 is located substantially coaxially within the insert l3, assuming that the shell or insert is cylindrical, which is customary but which need not limit the scope of the invention.
  • the screw 4 is on an upright axis.
  • the central part extends radially as respects such axis so that the cams or ramps 9 are formed on outer portions thereof, but here it will be seen that instead of two jaws or members 2, there may be but one that is movable if the second or other jaw is engageable with an opposing wall portion of the shell l3.
  • a multiplicity of jaws could be used, such as two, three, four etc., so long as the radially expansible means-including the screw 4 and the cams 8,9-causes the apparatus to become rigid with the shell 13.
  • the guides 1 may be regarded as part of the force-exerting means, because they are integral with the portion that has the internal thread 5.
  • the spindle or screw 4 is threaded into the portion 5 and its unthreaded lower part isjournaled in the part 6 and has a head accommodated by the under portion of the part 6 on which the vibrator 7 is mounted.
  • one jaw 2 is a first movable member and the opposed jaw is a second member engageable between the central part 6 and the proximate shell wall portion.
  • both jaws or members 2 are guided as duplicates, and this is true when three, four etc., jaws are used.
  • the apparatus being of considerable weight, may be lowered into the shell by any conventional means and is preferably located intermediate the upper and lower ends of the shell 13, the top of which is of course open and the upper end of the screw 4 is accessible through this open top.
  • the insert is of such large diameter as to exceed the extent of the outer, wall-engaging portions of the jaws or members 2
  • additions 15 may be used to close the gap.
  • the vibratory forces have a reach of effective area substantially throughout the height of the shell 13, as shown by the dimension 16. Because of this feature, the apparatus need not be repositioned and the forces are uniform to assure a satisfactory compaction of the: mass or material M. Because the expansive forces exerted by the apparatus on the shell rigidify the apparatus with the shell, it is assured that the forces from the vibrator 7 are appropriately conducted to the shell.
  • the apparatus may be inexpensively constructed. It is easy to operate, is simple and has a long life. There are relatively few moving parts and the design is such that more than adequate clamping or expansive forces may be manually accomplished, but it is obvious that power-operated refinements may be resorted to if desired.
  • Apparatus for mounting a vibrator within the upright annular-walled shell of an electric are or induction furnace for compacting particulate refractory material in the annular space between the shell and the surrounding refractory wall, comprising a central part positionable substantially centrally within the shell and including a portion adapted to carry a vibrator, and radially expansible means carried by the central part and operative to exert radially outwardly opposed forces against interior wall portions of the shell so as to rigidify the apparatus with the shell and to transmit vibratory forces to the shell, said central part including an outer portion in the form of a cam inclined to the lengthwise extent of the shell, and the radially expansible means including a first member having an inner portion riding the cam and an outer portion engageable with a proximate portion of the shell wall and at least a second member engageable between the central part and the shell wall in opposed relation to the first member, biasing means operative between the central part and the first member for biasing said first member inwardly and away from the shell wall portion,
  • the radially expansible means includes the first member and at least a similarly constructed and mounted second member, and the force-exerting means is operative simultaneously on both members, and second biasing means is operative on the second member to bias said second member inwardly.
  • the central part rotatably carries an upright screw having a top end accessible through the open upper end of the shell
  • the force-exerting means includes said screw and an element threaded thereon and engaging the first member so that rotation of the screw causes the first member to ride the cam in said radially outward direction.
  • the vibratorcarrying portion of the central part is an under portion to carry the vibrator below said part, said under portion is hollow and accommodates part of the force-exerting means.
  • the force-exerting means includes an upright screw rotatable in the central part and having a lower head comprising the aforesaid part accommodated by said hollow under portion.
  • Apparatus for mounting a vibrator within the upright annular-walled shell of an electric are or induction furnace for compacting particulate refractory material in the annular space between the shell and the surrounding refractory wall comprising a central part positionable substantially centrally within the shell and including a portion adapted to carry a vibrator, and radially expansible means carried by the central part and operative to exert radially outwardly opposed forces against interior wall portions of the shell so as to rigidify the apparatus with the shell and to transmit vibratory forces to the shell, said central part including an outer portion in the form of a cam inclined to the lengthwise extent of the shell, and the radially expansible means including a first member having an inner portion riding the cam and an outer portion engageable with a proximate portion of the shell well and at least a second member engageable between the central part and the shell wall in opposed relation to the first member, means mounting the inner portion on the central part for relative back and forth movement, and force-exerting means acting between the central part and the first member
