HENRY A. HILLS, OF GRAND RAPIDS, MICHIGAN.

CONDENSER.

Specification of Letters Patent.

Patented Feb. 12, 1918.

Application led .Tuly 28, 1916. Serial No. 111,808.

To @ZZ fuwm it may concern.'

Be it known that I HENRY A. Hints. a citizen of the United tates, and a resident of the city of Grand Rapids, in the county of Kent and State of Michigan. have invented certain new and useful Improvements 1n '.Condensers; and I do hereby declare that still, although of course well adapted for use in connection with other apparatus wherein a condensing effect is desired.

It is an object therefore of this invention to construct a condenser presenting a large condensing surface to an entering vapor with the surfaces so disposed that as the vapor is condensed thereon it flows rapidly by gravity through the condenser', and with a counter-current of a cooling medium to maintain said condensing surfaces cool to not only condense the vapor but to thoroughly cool the same as it proceeds through and leaves the condenser.

It is also an object of this invention to construct a vertical tube condenser provided with a distributing means at the entrance end thereof to direct the vapor to be condensed so that the same flows through the various different tubes, thereby utilizing the full effect of the condenser to condense the 'apor and cool the condensates as they leave the condenser.

It is furthermore an object of this invention to construct a condenser embracing an upright cylinder and a plurality of tubes extending therethrough and sealed therefrom at the upper and lower ends thereof to admit a flow of vapor into the upper end of said tubes for condensation therein, and with -:inlet and outlet means in said c vliuder to introduce and promote a fiow of cooling liquid around said tubes.

It is finally an object of this invention to construct an improved type of condenser of large capacity designed to condense and cool a fiuid admitted thereinto.

The invention (in a preferred form) is illustrated in the drawings and hereinafter more fully described.

In the drawings:

Figure l is a central vertical section with parts in elevation, of a condenser embody- -ing the principles of my invention.

ig. 2 is a section taken on line 2 2 of Fig. 1. V y Fig. 3 is a section taken on line 3 3 of Fig. 1. As shown in the drawings:

The condenser consists of au outer shell 3, lwhich. as shown, is open at its upper end 'and secured therein are a series of upright condensing tubes 15, all communicating at theirvupper ends through an apertured plate or head 1G. on which there is hrazed, riveted, or otherwise tightly secured thereto a conical hood 17, affording a con'ipartment for the vapor to be condensed prior to introduction into the condenser tubes. The outlet pipe 2, from a still is connected into the upper end of said conical hood 17. Nithin said hood above the plate 1G. is a distributing screen or apertured plate 18, shown as rectangular, and acting to insure an even distribution of the entering fluid to the different condensing tubes 15. by passage through the apertures in said plate and dispersion over the edges thereof. between which and the wall of the hood, clearance is provided. The lower ends of said condensing tubes 15. are connected through a crown sheet 19. which is rigidly secured by its fianged periphery to the inner walls of the cylindrical casing 3, of the condenser by riveting, brazing.' or otherwise. Connected to said cylindrical casing 3. below said crown sheet 19. is a conical bottom afferding a receiving compartment for the condensates into which the discharge pipe 1l, is connected. An inlet pipe for cooling water, denoted by the reference numeral 21. is provided, which communicates through the lower end of the cylindrical casing 8, and an outlet pipe Q2. is connected at the upper end thereof, so that water admitted into the condenser completely surrounds the condensing tubes l5, flowing upwardly therearound.

The operation is as follows:

The fluid introduced into the condenser through the pipe 2. for condensation strikes the distributing plate 18, and is broken up and caused to spreads in ditferent directions and then passes downwardly for passage through the condenser tubes 15, so that all ot' said condenser tubes are utilized to condense the fluid. The fluid after condensing in said tubes, flows by gravity downwardly therethrough subjected to the cooling action of the liquid surrounding said tubes, so that as the condensate flows outwardly from the condenser it is thoroughly cooled. y

I arn aware that various details of construction Inay be varied through a wide range without departing', from the principles of this invention, and l therefore do not purpose limiting the patent granted otherwise than necessitated by the prior art.

'I claim as I'ny invention:

l. A condenser com risinan outer c liiider open at its upper end, a crown plate in the lower end of the cylinder, a conical bottoni rnernber secured to the cylinder below the crown plate, a plurality of tubes connected to the crown plate, an apertured head plate secured to the tubes, a conical hood se cured to the head plate, and a rectangular apertured distributing platerin said hood having spaces around the edges thereof and the hood. c

2. Acondenser comprising an outer cylinder, tubes therein, a plate in the bottoni of the cylinder through which the tubes open, a lnernber secured to the cylinder below the plate, a plate near the top of the condenser through which the tubes open, a hood secured to the plate, an apertured distributing plate in the hood having a channel between the edge thereof and the hood adapting the uid to be condensed passing through the distributing plate and diiiu'sing around the edges thereof, and an inlet and outlet pipe opening into the cylinder.

In testimony' whereof l have hereunto subscribed my `name in the presence f two subscribing witnesses.

, HENRY A. HILLS.
