Definitions

  • the present invention relates to anarob1c chambers.
  • the object of the invention is to provide a special chamber for allowing any substance to be safely manipulated in any gas and out of contact with the external atmosphere.
  • Figure 1 is a perspective view.
  • Fig. 2 is a detail view showing the method of mounting the manipulating gloves in the openings of the chamber.
  • Fig. 3 shows on a larger scale an arrangement for detecting the presence of air in the chamber.
  • the anaerobic chamber of the present invention consists of an entirely closed box a preferably of parallelepiped shape. On the front side of said box are provided three openings b c el and on the rear side two openings b and d' facing the openings b and d respectively in the front side.
  • the openings b and b and d and d are large enough to allow free passage to the hands and arms of the operator; the central opening c is large enough for the admission of the various obJects and apparatus to be used in the box.
  • the said object is introduced at the end of the rubber tube.
  • the end of said tube being then held firmly, the object is caused to move forward in the tube by working on it from the outside; when the object has reached the opening c the operator takes hold of it with his hands after having inserted the latter in the gloves e.
  • a quick and easy method consists in introducing the gas by means of a radiator g placed at a suitable position in the apparatus, for instance as shown in Fig. l on the right hand side of the apparatus.
  • This radiator consists of a tube/lt extending into the interior of the box and connected with a series of small vertical tubes perforated at intervals with holes through which the gas for l lbox through the holes jin the left hand side of the box Fig. 1.
  • the holes y' are closed by means of Stoppers or taps.
  • the gas inlet is closed by means of a tap or other means.
  • a gas analysis could be made by collecting gas from the interior of the box, for instance through one of the openings j; however it is much simpler and more expedient to operate in the following manner
  • a benzene or the like lamp lo is placed, for instance, at the right hand side near the front of the box. Said sov lamp can be lighted at will by means of an electric current, but will not burn unless the latmosphere of the box contains oxygen.
  • Anaccumulator Z and a sparking coil m are placed outside the box and a lamp lo provided with a copper igniter o is placed inside.
  • the positive terminal of the aclighting the lamp is as folcumulator is connected to the terminal p If oxygen is' present in the box the lamp is lighted by the sparks produced between the igniter o and the burner of the lamp; if there is no oxygen present the lamp does not light.
  • the switch g enables the lighting sparks to be passed or stopped at will. If the lamp lights it indicates that oxygen is present in the box, in which case the air must again be displaced with nitrogen.
  • the chamber of the present invention may be used for many purposes, but it will suffice to mention some of them 1. With such a chamber one can safely manipulate substances which evolve the most dangerous vapors.
  • Any substance can be manipulated in any gas without fear of such substance undergoing alteration through contact with the outer atmosphere.
  • An anaerobic chamber for safely manipulating lany substance in any gasand ⁇ out of contact with air comprising a completely closed box provided with a plurality of manipulating hand holes, long soft manipulating gloves extending through said hand holes into the interior of said box, each glove being firmly secured with its open end to one of the said hand holes so as to make an air tight joint, an opening provided with a long rubber adapted to Vprevent all communication between the interior of the box and the outer air and serving to introduce the objects to be manipulated into said box, and means for removing air from said box.
  • An anarobic box as set forth in claim 1 in which the air is displaced from the box by a current of gas discharged from a jet provided within said box.
  • means for detecting the presence of air in the box comprising a benzene or the like lamp at the top of which electric sparks are produced, which sparks light said lamp when any oxygen is present inside the box.
