Letters Patent No. 103,326, dated May 24, 1876; antezlated May 10, 1870.

IMPROVED CONDENSER FOR STILLS.

The Schedule referredto in these Letters Patent and making part of the name.

il 'o all whom it may concern to which our invention appcrtains to make and use accompanying drawmg making part of this specification, and in which the same, reference being had to the our invention is representedby a plan view.

This inventionconsists in the peculiar construction of condensers, as hereinafter described, whereby increased-cooling surface is obtained without the enlargement of the apparatus, and condensation is brought to a greater, degree of perfection, and more expeditiouslyproduced than heretofore.

Our invention will be fully understood fi'oln thefollowing detailed description.

Referring to the drawing-'- A represents a trough or box containing the condensing-tubes, which it is intended shall be completely submerged in water while the apparatus is in use, the troughibeing so arranged or situated that water may be allowed to flow through it in a constant stream, and escape at the end a which is lower than the side of the trough.

B is the head or receiver of the'coudenscr, ele vated slightly above the bottom of the trough, as shown, and having a large opening I) in the top,'into which enters a pipe from the still.

G O are two gradually-tapering pipes, extending from and communicating with the receiver B, and

'having a slight downward inclination, which facilitates the flow: of the condensed vapors toward the point of discharge.

These pipe's O G gradually approach each other and form the large pipe D, which becomes smaller,

and inclines downward toward the lower end of the trough, where it is turned abruptly to one side and passes out at c, as the outlet of the condenser.

' The condensation in this apparatus is as follows, viz:

'ater is flowingthrough the trough A and en- 'tirely covering the pipes and part B. Vapors from the still enter and fill the receiver, then pass through the pipes 0 (land D, being, throughout the entire distance, cold, and graddolly-diminishing surface of the submerged pipe which retard the flow, and thus,

perfectly condense the vapor which is discharged in liquid form at the outlet e.

It isevident that CODdBIlSillg-Slll'fit-CG is gained by the employment of the two pipes C 0, instead of a single pipe moving twice the distance of each pipe 0. Besides, the smaller the pipe the more thoroughly will its interior be cooled.

The object in making the pipes O O D tapering," is to constantly retard the passage of thevapors,

and thereby aii'ord amplc time for their condensa-- tion. Again, if the pipe were of the same size throughout its length, the condensation would not probably be complete, because, after a portion of. thevapors had been condensed, the remainder would pass out without contact with the pipe, and thus escape uncondensed.

The simplicity of our condenser will generally recommend it.

Having thus described our invention,

\Vhat weclaim as new, and desire to secure by Let ters Patent, is-

1'. The combination of the receiver B, pipes O G and D, and outlet 0, when constructed and arranged substantially as described.

2. In combination with the parts named in the last claim, the trough A, combined and arranged substan tially as-and for the purposes set forth.

The above signed by us this 13th day of September, 1869.
