Definitions

  • the invention relates to a device for adjusting the spatial position of a specimen carrier freely rotatable about two spatial axes arranged in perpendicular relation to each other and located inside a treatment chamber.
  • the specimen carrier is rotatable about its axis and mounted on a crosspiece of a U-shaped strap the two legs of which are rotatable on a platform slidable inside the treatment chamber about an axis arranged in perpendicular relation to the axis of rotation of the specimen carrier. All motions of the specimen carrier are derived from separately driven spindles extending in the longitudinal direction of the treatment chamber.
  • this aim is achieved by the provision of two individually rotatable driving shafts arranged in concentrical relation to each other and preferably extending through the Wall of the treatment chamber, the rotation of the specimen carrier about its two axes of rotation on the intersection of which it is preferably located, being derived from the said driving shafts.
  • the insertion of the device in the chamber is greatly facilitated, as it may be freely introduced into the chamber through a single aperture.
  • this design offers an additional advantage by ensuring simple and positive sealing of the interior of the treatment chamber against the open air, which is particularly important for high-vacuum treatments. In that case, the one and only aperture of the chamber wall can be readily sealed by conventional means.
  • the coaxial arrangement of the driving shafts facilitates the operation of the device since all control handles are neatly grouped and arranged over a comparatively small area.
  • one of the driving shafts of hollow design can be axially slidable, the specimen carrier being additionally orientable about a third spatial axis arranged in perpendicular relation to its two axes of rotation, allowing it to be preferably elastically pressed against a cooling body provided in the treatment chamber.
  • the specimen carrier can be cooled, as frequently required for cer- Patented July 25, 1967 tain types of treatment, by direct contact with the cooling body, thereby reducing the time during which the treatment has to be interrupted.
  • the specimen can be periodically heated, the use of a combined heating and cooling body being most convenient in many cases. Nor will the easy sealing of the chamber be impaired by the additional degrees of freedom required for the displacement of the specimen carrier.
  • two solutions are suggested according to the invention, one of which consists in a relative axial displaceability of the concentric driving shafts from which the swiveling motion of the specimen carrier is derived.
  • an additional, separately rotatable tubular driving shaft, coaxially extending through the hollow shaft is provided, from the rotation of which the swiveling motion of the specimen carrier is derived.
  • a preferred embodiment of the invention provides for the gimbal suspension of the specimen carrier by means of two U-shaped bows encompassing each other and interconnected by means of articulations attached to their legs, the shaft of the specimen carrier being rotatably mounted on the crosspiece of the inner bow and the outer bow centrally fixed on the inner extremity of the outer hollow shaft. Consequently, whatever its spatial position, the specimen carrier will always be arranged in central relation to its axes of rotation so as to remain in any case Within the direct effective range of the source of radiation or vaporization.
  • a bevel gear can be non-rotatably connected with the inner bow and engage with a bevel gear at the inner extremity of the hollow driving shaft, an additional bevel gear being interpolated, if necessary, between the above-said bevel gears.
  • FIG. 1 is a schematic cross-sectional view of an embodiment of the invention
  • FIG. 2 a longitudinal cross-sectional view of another embodiment of the invention.
  • the specimen carrier 1 is centrally arranged inside a treatment chamber 2 enclosed in a biaxial housing 3.
  • the specimen carrier 1 is rotatable about its own axis and mounted on a swivel head 4, whose center coincides with the intersection of the two aXes A A and BB of the housing 3.
  • the swivel head 4 is connected with the inner end of a tubular shaft 5 arranged in concentrical relation to the axis AA and inside which a central driving shaft 6 is freely rotatable and longitudinally slideable.
  • the swivel head 4 is orientable about a 3 spatial axis C arranged in perpendicular relation to the two axes A-A and BB.
  • the tubular shaft 5 extends through a lateral mounting flange 9 of the housing 3 and is both axially displaceable and rotatable in the bore of the flange 9.
  • the aperture of the housing 3 opposite the flange 9 leads to a vacuum pump as indicated by the arrow for the purpose of permitting the evacuation of the treatment chamber 2.
  • Reference numbers 10 and 11 designate the flanges for closing the lower and upper portion respectively, of the treatment chamber 2 which also serve to receive the vaporization 'or irradiation sources when treatments of this kind are to be performed.
  • a cooling cylinder 12 is also mounted in the preferably thermally insulated treatment chamber 2 opposite flange 9, said cylinder serving for the periodic cooling of the specimen carrier 1 as explained hereafter.
  • the said cooling cylinder 12 may also comprise a cylindrical extension made of a heat-conducting material such as sheet copper, surrounding the specimen carrier 1 and appropriately recessed for the purpose of faciiltating vaporization or irradiation of objects placed on the specimen carrier 1.
  • the driving shafts 5 and 6 comprise a control handle each, designated by reference numbers 7 and 8 respectively, at their respective extremities.
  • the rotation of the specimen carrier 1 about its axis is derived from the central driving shaft 6 and brought about by turning the handle 8.
  • the specimen carrier 1 is swivelled about the axis C.
  • the carrier 1 is swivelled away by 90 degrees from the position shown in the drawing, it occupies the position indicated by the dash-dotted lines where its axis coincides with the axis AA of the driving shafts 5 and 6.
  • the carrier 1 can be moved towards the cooling cylinder 12 by the axial displacement of the hollow shaft 5 by means of its handle 7 and cooled by direct thermal contact.
  • the specimen carrier 1 is furthermore freely rotatable about the axis A-A by means of the handle 7.
  • a cooling bridge such as an elastic outrigger, can be provided for the cooling of the specimen carrier 1 either inside or outside the treatment chamber.
  • a gimbal suspension is provided for the specimen carrier 1.
  • the specimen carrier 1 is non-rotatably connected with its shaft by means of a carrier 13 and equipped with a helical spring 14 supported by a shoulder of the shaft 15.
  • the pivot bearing 16 of the shaft 15 is located on the crosspiece of an approximately U- shaped inner bow 17.
  • the parallel legs 18 of the said bow have alining crossbores defining pivot bearings for the pivots 19 of the U-shaped outer bow 20 whose crosspiece 21 is centrally connectedwith the inner extremity of the outer tubular shaft 5.
  • the tubular shaft 5 is so designed as to be rotatable and slidable in a bore of the flange 9 and sealed off against the flange 9 by means of a packing washer 22.
  • a tapered chuck 23 attached to the flange 9 and comprising a threaded locking ring 24 makes it possible for the tubular shaft 5 to be fixed in any desired position.
  • the tubular shaft 5' extends through a separately rotatable hollow driving shaft 5 arranged in coaxial relation to same, which can be non-rotatably connected with the outer tubular shaft 5 by means of an additional clamping device consisting of a cone 23' and ring 24'.
  • a packing washer 22' serves to seal the shafts 5 and 5' off against each other.
  • a control grip 7' is mounted on the outer extremity of the hollow shaft 5' and a bevel gear 25 on its inner extremity.
  • the central driving shaft 6 extends through the hollow shaft 5', being sealed off against the latter by an additional packing washer 22" and equipped with a crank 34 at its outer extremity.
  • the inner extremity of the central driving shaft 6 also carries a bevel gear 28.
  • the bevel gears 25 and 28 constitute the drive gears of two independent bevel gearings deriving the rotating and swivelling motions of the specimen carrier 1 from the concentric driving shafts 5' and 6.
  • the gearing for swivelling the inner bow 17 comprises the bevel gears 25, 26 and 27, the last-mentioned one being non-rotatably connected with a leg 18 of the inner bow 17, whereas the intermediate bevel gear is rotatably mounted on the outer how 20 with an inclination of 45 each in relation to the axes of the bevel gears 25 and 27.
  • the gearing for driving the shaft 15 of the carrier 1 comprises a total of six bevel gears 28 through 33, among which the two middle bevel gears 30 and 31 are nonrotatably interconnected and supported by a sleeve rotatable in the crossbore of the leg of the inner bow 17 located opposite the bevel gear 27, the pivot 19 of the outer bow 20 protruding into the axial bore of said sleeve.
  • the intermediate bevel gear 29 is rotatably mounted on the outer, and the intermediate bevel gear 32 on the inner bow.
  • the axes of the intermediate bevel gears 29 and 32 are inclined by 45 in relation to the axes of the adjacent bevel gears with Whom they are in engagement.
