CHEMICAL APPARATUS.-
SPECIFICATION forming part of Letters'Patent No. 700,268, dated May 20,1902.
Application filed October 28, 1901. Serial No. 80,239. (No model.)
which is of suitable structure to'facilitate the estimation of the nitrogen, both by saving time in the process of distillation and by avoiding a lossofmaterials. I accomplish this object by the device shown in the accompanying drawing, in which the figure is a vertical section, partly broken away, of a device constructed according to my invention.
' In the device shown the tank 1. is support ed on standards 2 and contains thecoil 3,
Whichconnects with the pipe 41 at its upper end' and with the discharge-pipe 5 at its lower end. Said tank and coil together form a condenser. The chamber 6 and pipe'7 form an extension of the pipe 4. At the outer end of the pipe 7 is a chamber 8, havingan upwardly-extending neck 9 anda depending tubular extension 10. A sleeve 11, made of resilient material, such as rubber, surrounds the lower end of the extension 10, forming therewith a hollow stopper for the distillation-flask 12. A steampipe 13 enters the extension 10 above the sleeve 11 and extends to the bottom of the Said steam pipe connects with a main pipe 14: and is provided with a valve 15. The pipe 14is connected with a suitable steamsupply, which is not shown in the drawing. The pipe 16 leads from the receptacle 17, through the stopper 18 and extension 16, to the bottom of the flask 12. The valve 19 controls the passage of liquid from the receptacle 17 through the pipe 16. 1
The pipe 4, chamber 6,-pipe 7, and. chamber 8 are preferably made of metal and are rigidly connected, so as to support the cha n- 50 ber 8. Iprefer this structure to the use of glass bulbs with rubber fittings, since it re- Thefclamp 20 is supported on the'rod 24,1
which is held in the block-by means of the set-screw 26. The block 25 is vertically slid-.
able 'on the rod 27 and held by means of the set-screw 28. The rod 27 is rigidly secured to the tank 1. The clamp 20 will usually remain at a fixed height-on the rod 27and is, made adjustable thereon, so that same may be moved when desired to suit the position I of the flask on the sleeve 11.
29 -represents the mouth of an inlet-pipe through which the tank 1 is supplied with water. 30 represents the mouthof an outletpipe which maintains'the water at the desired level in said tank. Thepipe 5'is connected by means of the flexible section 31 with the A pipe 32 in the receiver 33.-
The operation of the device shown will be understood from the following description of a method of estimating nitrogen by means of said device: The material containing thenit-rogen to be estimated is first digested in the flask12 by using concentrated sulfuric acid and mercury. After the digestion is completed the flask is allowed to cool, and its contents is then diluted with distilled water. The flaskis then connected to the other parts of the apparatus, as shown in the drawing. Sodium hydrate is next addedfrom the receptacle 17 by openingthe valve 19. At the same time steam is turned into the fiask-12 by opening the valve 15, thus aiding in mixing the alkali with the acid. Potassium sulfid is then added through the receptacle 1-7 to precipitate the mercury. The steam will then be allowed to continue to flow, the vapors beingcarried up through the chambers 8 and 6 and into the condenser until all of the nitrogen has been carried into the receiver 33 in the form of ammonia. The chambers'8 and'6 permit the tails of the device shown may be altered without departing from the spirit of my invention. I therefore do not confine myself to such details, except as hereinafter limited in the claims.
\Vhat I claim as my invention, and desire to secure by Letters Patent, is-
1. A chemical apparatus comprising a condenser; a chamber communicating with said condenser and having a tubular extension; a resilient sleeve mounted on said extension and forming therewith a hollow stopper; and a steam-pipe entering said extension above the stopper part, passing out through the interior of the stopper, and having a valve outward of its entering part.
2. A chemical apparatus comprising a condenser; a chamber communicating with said condenser and having a tubular extension; a resilient sleeve mounted on said extension and forming therewith ahollow stopper; a receptacle outside of said extension having a pipe entering said extension above the stopper part, passing out through the interior of the stopper, and having a valve controlling the passage through said pipe; and a steampipe entering said extension above the stopper part, passing out through the interior of the stopper, and having a valve outward of its entering part.
3. A chemical apparatus comprising a condenser; a chamber communicating with said condenser and having a tubular extension; a resilient sleeve mounted on said extension and forming therewith a hollow stopper; a steampipe entering said extension above the stop per part, passing out through the interior of the stopper, and having a valve outward of its entering part, and an outer clamp adapted to coact-with said stopper in engaging and supporting a flask.

5. lmhemicalapparatus comprisingacham her having an outlet-passage in its side, said chamber having a neck extending above same adapted to receive a stopper; a depending tubular extension on said chamber having on its lower end a resilient sleeve forming therewith a stopper; a flask removably fitting the stopper end of said extension; a receptacle above said neck having a pipe passing through said neck and tubular extension to the bottom of the flask and having a valve above said neck controlling the passage through said pipe; a stopper securing said pipe in said neck; and a second pipe, independent of the outlet-passage and independent of the other pipe and said receptacle, entering said extension above the stopper part of same, passing through the interior of said extension to the bottom of the flask, and having a valve outward of its entering part.
(3. A chemical apparatus comprising a suitably-supported condensing-tank, a condensing-coil therein having a supply-pipe extending outwardly and downwardly from said tank, the chamber 6, pipe 7 and chamber 8 rigidly connected and supported by said tank in the relative positions shown, said chamber 8 having a depending tubular extension, and a resilient sleeve mounted on said extension and forming therewith a hollow stopper adapted to engage and support a distillationflask substantially as shown.
