Definitions

  • At least one of said tubes communicates through its lower end with the outside of the chamber, preferably through the agency of a sluice, and the arrangement includes inside the chamber at least one shiftable trough the lower end of which is adapted to be brought into registry with the upper end of any one of States Patent ice Patients! Mar. as, reel moving inside said cap round an axis passing through the center of the latter.
  • the tubes/housed inside the chamber havetheir upper ends located on a" spherical cap the conv cavity'of which faces upwardly and there is provided a movable trough suspended'through a cardanrjoint and distance; said cables are intended for the transportation of various articles and pass through the troughs.
  • the troughs 15 and 16 form the hypotennses of the two deformable right-angled triangles the median lines 21, 22 of which have a constant length and consequently the lower ends 2-5 and 26 of said trou hs move in a horizontal plane when their upper ends follow the axial movements of the turret. It is apparent that it is possible to obtain experimentally a scale of references showing which pair of symmetrical tubes registers at any moment with the lower openings 25 and 26 of the troughs.
  • the lower element 10 of the turret is rigid'with the chamber 1 while the upper element 11 is axially and revolubly shiftable.
  • element 11 has a ring gear 'dll.fixedlyrmounted thereon, which gear is engaged by the'pinion dldriven by motor 42 for rotating said element .11.
  • Said;ring gear is of sufiicient length to allowsaid element 11 tobe axially moved while said gear remains in engagement with said pinion, and this axial or longitudinal moverent of element 11 is provided by a ,lingitudinally extending rack 43 fixedly mounted thereon which is in engagement with a pinion 44 driven by motor 45.
  • the length of the tubes 1'3 and 14 and, conse- .quently, the height of the turret lt311 may be substantially reduced,pprovided the added length of the tubes andtroughs such as 13, .15 on the one hand .and 14,
  • An apparatus for introducing articles into and removing the same out of a chamber comprising an open end chamber, a turret capping said chamber open end and capable of revolving around and moving longitudinally along the longitudinal axis of said chamber, a pipe system fixedly mounted in said turret for movement therewith and arranged coaxially with reference thereto, at least one tube located in said chamber and communicating through an end with the outside of said chamber, a series of tubes substantially parallel with said first mentioned tube and positioned inside said chamber, a pair of troughs positioned within said chamber and each having one end thereof in register with an end of a corresponding pipe of said pipe system, a spindle extending across said turret and to which each trough is pivotally secured through said end thereof, a pair of links the length of each of which is equal to half of the length of each trough each being pivotally connected at one end to the middle of one of said troughs, a horizontal carrier adapted to revolve around but not along the axis of said turre
