PATENT OEEIcE.

ROTATING HEAT-TRANSFERRING DEVICE.

SPECIFICATION forming part of Letters Patent No. 769,557, dated September 6, 1904.

Original application filed May 2'7, 1902, Serial No. 109,197. Divided and this application filed February 7, 1903. Serial No. 142,323. (No model.)

To (LZZ whom, it nuty concern:

Be it known that I, LEOPOLD VON MAY, a subject of the Emperor of Austria-Hungary, and a resident of Ungarisch-Ostra, Mai-graviate of Moravia, Empire of Austria-l-Iungary, have invented a new and useful Improvement in Rotating Heat-'lransferring Devices for Cooling, Distilling, Heating, Evaporating, and Condensing Liquids and biases, of which the following is a specification.

The invention relates to that class of rotating heat-transferring devices to be used for cooling liquids or gases, for condensing exhaust-steam, or for heating or distilling liquids, which comprises a group of pipes each connected at one end with one of two chambers and at the other end with the other of said two chambers, which chambers communicate one with an inlet-pipe and the other with an outlet-pipe, the said inlet and outlet pipes being arranged in line with each other and constituting shaft-journals, about the common axis of which the whole structure of chambers and pipes rotates.

The improvement consists in the novel structure hereinafter described and claimed embodying such pipes and chambers and journals, the said improvement having been described in my application, Serial No. 109,197, for United States Patent filed May 27, 1902, of which this application is a division.

Figures 1 and 2 of the drawings represent vertical sections at right angles to each other of a rotating heat-transferring device embodying my invention.

a designates a casing for containing liquid to be heated or cooled or a heating or cooling liquid, represented of substantially cylindrical form.

(Z and c are two short hollow shafts arranged in line with each other and fitted to rotate in stuffing-box bearings (Z e*'in opposite sides of the casing a. Between these shafts (Z and c and connecting them there is a box which is divided by a longitudinal partition 7L2 into two chambers h h, situated side by side. The

With the hollow shaft 6.

the chamber 71., at the right, communicates with the hollow shaft (2, but not with the one (Z. The only communication between the two chambers [L la is through the numerous group of heating or cooling pipes m m, which have a curvature approximately concentric with the axis of the alined shafts (Z and a and which almost surround the said chambers 7t 7t.

On that side of the casing (a at which the hollow shaft (Z projects through the stuflingbox (Z there is provided a stationary chamber 9, with which the hollow shaft (1 communicates and to which the heating or cooling medium or the liquid to be heated or cooled or steam or vapor to be condensed is introduced at f. The open outer end of the hollow shaft 0 is connected by a stufling-box c with a stationary outl.etpipe 1-. The said shaft 0 has applied to it any means for rotating it a gear p, for example. This rotation carries with it the whole structure a (i ll, 7/ m m, of which the hollow shafts (l c constitute journals. The heating or cooling medium or the liquid to be heated or cooled or the steam or vapor to be condensed introduced through f and g enters into and passes through the hollow shaft or journal (Z, thence into the chamber lb, whence it circulates through the numerous heating or cooling pipes m m to the chamber it, through which it or its condensation product passes to the hollow shaft or journal 0, which forms an outlet to the pipe r.

The box containing the chambers 72, his represented as constituted by a single casting divided into two compartments by the longitudinal central partition If. In each of these compartments or chambers there is a longitudinal slot j to permit access to the interior thereof and to the mouths of the pipes 111. \Vhen the device is in operation, the longitudinal slots y' are closed tightly by lids s.

Vhat I claim as my invention is In a rotating heat-transferring device, the combination of two short hollow shafts arranged in line with each other and constituting journals, a box arranged between said hollow shafts and divided by a longitudinal partition into two chambers which communicate one with the interior of one and one with the interior of the other of the so-constituted journals, and a group of pipes nearly surrounding said box, each one of the pipes having one end connected to one chamber and its opposite end to the other chamber to open communication between the two chambers through said pipes, substantially as herein described.

In testimony that I claim the foregoing as my invention I have signed my name, in pres- IO ence of two Witnesses,this 24th day of January,

LEOPOLD VON MAY.
