Application filed February 14, 1914. l Serial No. 818,693.l

T 0 all whom t may concern y Be it known that I, ERIC BERKELEY HIG- GINs, Ph. D., a subject of theY King of Great lBritain and Ireland, residing at TvVallasey,

Cheshire, England, have invented certain new and useful Improvements in and Relating to Mixing-Machines, of which the following is a specification.

This invention'relates to mixing machines adapted for the adinixture of gases with liquids, and the invention has for its object to provide a mixing machine for this purpose of high efficiency and effectiveness.

The machine is more especially intended for use in the hydrogenatio-n of fatty acids but is of general application in any case in which anV intimate admixture of gases and liquids, of'liquids and solids, or of various liquids or any other bodies whether solid, liquid or gaseous is desired to be expeditiously and thoroughly eected. 'The invention is applicable for example to the oxida tion of liquids 'or solids with liquid mixtures such as for example the conversion of ferrous hydrate to ferrie hydrate or to the drying ofV gases where the liquid in the mixer is a water absorbing liquid, or the scrubbing of gases.

According to the invention I provide the beaters or vanes with a number of conical cups closed at .their bases and open at their narrower ends where they are mounted upon the plate formingthe beater or vane. The plate is provided with a hole of correspending size to that of the open end of the conical cup and the cup is mounted on the plate so that the opening in the cup is coincident with the hole in the plate. Such conical cups are uniformly distributed and are mounted upon one side of the beaters or vane-s. Between the respective cups, however, holes are formed in the plate. These holes are advantageously arranged Vall over the plate so as to form continuous.

longitudinal and transverse rows of holes intermediate of the respective rows of conical cups. By such means on the rotation of the beaters or lvanes the cups pass into the liquid open end first. A quantity of the gas thus becomes imprisoned in the cups and as the beater or vane rotatesso does the liquid pass into the cup and the gas passes out. The gas continues to pass out throughout the course of the beater or vane through the liquid. Moreover, by the pro- Specification of Letters Patent. Fgb, a

vision of holes intermediate of the'cups in the manner described, the rush ofthe liquid through these holes carries the bubbles of lgasthrough with it, and thus the bubbles of are brought into ver with'the liquid.

The invention ycomprises the constructional features which are `.hereinafter described; Y y The invention is illustrated inthe accompanying'drawings in whichy'Figure `1 is 'a cross section of a mixing y intimate contact machine, Fig. 2' is a sectional plan 0n the llineA A (Fig. l) showing also a sectional plain through the jacket on the line A1, A1

According to'. the 'invention in its application to a `mixing machine as illustrated adapted for thehydrogenation' of fatty acids and the like, I provide a vessel a whose lower-part is cylindrical in form and vhas mounted longitudinally `therein the spindle b upon whichfthe beaters or varies c are carried. These beaters or vanes' are constructed of a number Vof plates. These may advantageously be-four in number disposed radially with reference to the lower part of the vessel and mounted equi-distant one from the other and maintained in that position by stays c1 suitably disposed or by other means.v rIhe beaters or vanes c are provided with a number of conical cups c2 closed at theirpbases and open at their narrower ends where they are mounted upon the plate forming thebeater or vane. The plate is provided with a hole c3 of corresponding size to that of they open end of the conical cup and the cup is mounted on the plate so that the 'opening in the cup is coincident with the hole in the plate.4 Such conical cups are uniformly distributed and are mounted upon one side of the beaters or vanes. Between the respective cups, however,l holes c4 are formed in the plate. These holes are advantageously arranged all over the plate so as to form continuous longitudinal and transverse rows of holes c* intermediate of the respective rows of conical cups c2. Y.

t By such means on the rotation yof the beaters or vanes c the cups c2 pass into the liquid open end first. A quantity of the gas thus becomes imprisoned in the cups c2 and as the beater or vane rotates so does the liquid pass, into the cup and the gas passes out. The gas continues to pass out throughout the course of the beater' or vane through the liquid. Moreover' by the provision of holes intermediate of the cups in thek manner described, the rush of the liquid through these holes carries the bubbles of gas through with it, and thus the bubbles of gas are brought into very intimate contact lwith the liquid. rI`he beaters or vanes c are provided of a length corresponding to that of the vessel so that thus in the rotation of the blades the liquid is compelled to pass through the hol-es provided in Vthe beater or vane plates. The Vlower part or' the Avessel is provided with a jacket CZ through Which steam may be passed by means of the pipe e or other heating or cooling medium by means of which the operation may be effected at any desired temperature. The upper part of the casing is advantageously extended beyond the path of the beaters or vanes and suitable fittings are provided for indicating the pressure Within the casing,V for the admission and outlet of gas and for the admission and outlet of the liquid. Thel vessel fr, is mounted upon two frames f which contact with the lower part of the vessel. Upon the top faces of each of these frames are bolted angle irons g extending the length of the vessel on each side thereof, and these angle irons g are riveted to the sides of the What I claim as my invention and desire to secure by Letters Patent is l. A mixing machine, comprising a casing, beaters or vanes adapted to rota-te within said casing-open cups of conical form mounted on said beaters or vanes, having their Vmouths at their smaller ends, the mouths of the said cups being disposed in the plane of the said beaters or vanes, substantially as described.

2. A. mixing machine, comprising a casing, beaters or vanes adapted to rotate Within the said casing so that their edges closely iit the inner Walls of the said casing, open cups of conical forni mounted on said beat ers or vanes, having their mouths at their smaller' ends, the mouths of the said cups being disposed in the plane of the said beaters or vanes, said beaters or vanes being provided with series of holes intermediate of' said cups, substantially as described.

3. A mixing machine, comprising a cas ing, a rotating shaft Within said casing, beaters or vanes mounted upon said shaft at right angles thereto and so as in their rotation to fit the inner walls of the casing, open cups of conical form mounted on said beaters or vanes with their mouthsdisposed in line with the said beaters or vanes, said Ybeaters orv vanes being provided with series Copies of this .patent may be vobtained for` ve cents each, by addressing the Commissioner of Patents.
