To all whom it may concern: 1

Be it known that I, SIDNEY G. BARNS'JEAD,

a citizen of the United States, and a resident of Cambridge, in the county of Middlesex and Commonwealth of Massachusetts, have invented certain new and useful Improve.-

' ments in Condensers, of which the following is a full, clear, and exact specification.

The object of this invention is the construction of an improved device for the condensation of water froma still, the same being especially designed for use in connection with a boiler heated by means. of a as burner. My improved condenser consists essentially of two concentric spaced cylinders into the annular chamber of which cold 7 water is supplied, and through the inner Fig. :2 is a cross section on the line 22 in Fig. 1. a

The steam producing portion of the still consists of a casing 1 provided with an apertured base 2 which supports a burner 3. Above the burner is a hollow ring 4 adapted to receivewater through a tube 5, and having numerous vertical tubes 8 connecting it with the receptacle 6. This receptacle films a. mouth 7 and a flange 9 provided with openings 10 for the escape of the products of combustion. Upon this mouth 7 there is fastened by means of thumb-nuts 11 a plate 12 from which rises the vapor escape pipe 13, the upper end of the latter having an elbow 14 which opens into the condenser proper. i 7

As shown in Fig.2, the body of this condenser is composed of two sheet metal cylintiers of unequal diameter, the smaller being spaced within the larger to form an annular space 15, The outer cylinder 16 and the inner cylinder 17 are attached to 'heads 19 and 20 which taper down to a. fit on the elbow 14, the head 19 tapering more thanthe head 20 in order to be brazed or soldered thereto as Well as to the elbow.

The head 21 at the other end of the cylin-. ders is stepped to provide two seats 22, 23 for the reception of the two cylinders, and to render the annular chamber 15 water tight in its separation from the chamber 24 within the cylinder 17.

A constant supply of cold water is supplied to the annular chamber through a. pipe 25 leading into the lowermost part of the same, and the circulation is maintained I therein by the outlet pipe 26 rising from the highest p r f he Chamber 24 and then descending to apoint directly over the cup 27. This cup is supported by and communicommunicates with the tube 5 so that the water from the chamber 24 passes to and" maintains the supply in the boiler tubes and receptacle 6. Whenever the level in this receptacle rises above the holes in the small tube 30 located within the tube 29, the ex cess escapes through such holes 31 down through the pipe 30 to any suitabledrainage.

The cook 32 is for the purpose of draining out the boiler tubes and receptacle whenever desired, and also for obtaining a supply of hot waterfor any purpose.

\Vithin the chamber 24 and attached to I the upper wall thereof is an oblique partition 33 whose lower edge and side edges'are spaced from the cylinder 17 as shown in Fig. 2, its obliquity being such that its lower edge is farther away from the elbow 14 than its upper end.

At the lowermost part of the head 21 is an outlet pipe 34 for the delivery of the distilled water to any desired receptacle.

The operation of this still is as follows: As the water in the boiler tubes 8 and the receptacle 6 is put into ebullition through the effect of the heat from the burner 3, the vapor arising therefrom passes through the pipe 13 and thence into the chamber 24.

Here it meetsthe oblique partition 33-and is diverted into direct contact with the portion of the cylinder 17 nearest the edges of the partition, and also nearest the freshest and coldest part of the inflowing water'coming from the pipe 25. Consequently, the steam and vapor passing down the chamber 24 is quickly condensed to water and descends through the pipe 34.

What I claim is:

A condenser comprising two concentric spaced unequal slightly inclined cylinders. the space between the cylinders having 70 cates with a tube 29 whose lower portion mar means for the circulation of a cooling fluid I through it, and the inner cylinder having lower end of'the plate being farther from the vapor-entrance than its upper end.

1 In testimony that Ifclmm the foregoing 10 invention, 1 have hereunto set my hand this 31st day of July, 1920; f

. SIDNEY G. BARNISJTEAD.
