INvENTaR UNITED STATES PATENT OFFICE.

ALBERT HENNING, OF LEY'I'ONSTONE, ENGLAND.

(GRANTED UNDER To all whom it may concern Be it known that I, ALBERT HENNING, a citizen of the United Kingdom of Great Britain and Ireland, and resident of 120 Harrow road,1Leytonstone, in the county of Essex, England, have invented certain new and useful Improvements in Means for Cooling Internal-Combustion Engines and other Machinery, for which I have filed an application in England Sept. 25, 1917, Patent No. 116,819, of which the following is a specification, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to means for cooling various parts of machinery such as bearings, pistons or the spaces in which these parts are working, also for apparatus or parts of same used in laboratories, also for apparatus for low temperature desiccation, for reducing blood pressure and hemorrhage, for scientific, domestic, commercial and other purposes where a safe and rapid reduction of temperature is required.

The invention may be broadly described as consisting in providing a case or carrier for a number of flasks, ampuls or equivalents, each charged with highly volatile liquid such as ethyl chlorid in conjunction with means by which upon certain predetermined movement of the case the said flasks or ampuls may be consecutively opened and brought to a position from which they will discharge thelr liquid contents into the article to be cooled, said article being placed in any convenient case, housing or receptacle for the purpose.

An example of my invent-ion is shown in the accompanying drawings in which Figure 1 is a front elevation of a case holding twelve ampuls adapted to be discharged one at a time through the same opening, and

Fig. 2 is a vertical section through the case shown in Fig. 1.

The drawings are largely diagrammatical and I have not thought it necessary to illustrate the article to be cooled, because, as above indicated a very large variety of articles may be operated upon and the means for holding same may be as desired.

In these drawings a non-rotating chamber a contains a rotatable case 1) into which the ampuls c are removably fitted in radial specification of Letters Patent. Patented June 28, 1921,

Application filed October 2, 1918. Serial No. 256,633. THE PROVISIONS OF THE ACT OF MARCH 3, 1921, 41 STAT. L, 1313.)

through apertures in the rim of the case b. A stop e is fixed to the chamber a and is arranged 111 the path of the projecting ends 11 and close to a funnel-like outlet f into which two strainers are fitted. This outlet is directed toward the object to be cooled.

Any suitable mechanical intermittent means may be employed to rotate the case b or it may be turned by hand and some indicating means or a stop, of which many forms may be suitable, is provided to insure the correct amount of rotation.

In use, the case is charged with the ampuls, containing say ethyl chlorid, and after the object to be cooled is in position and the apparatus is to be used, the case is turned sufficiently to bring one of .the projecting ends opposite the outlet f to reach which it must pass the stop 6, which snaps the ends off thus permitting the contents of the ampul to be discharged through the outlet. \Vhen the ampul so acted upon is emptied and a further cooling is necessary, the case b is turned one stage farther and thus the next ampul is opened and permitted to discharge its contents, and so on until all the ampuls are emptied, after which they are removed and a further supply is fitted into the case. It will be seen that three of the ampuls which I have numbered 1, 2 and 3 have been opened, the first two have been emptied and the third is in action and is discharging its contents, as shown by the arrow, through the sieves in the outlet. The severed ends of the ampuls are shown resting in the uppermost sieve which is slightly conical to prevent their interference with the fine jet of ethyl chlorid,

although I do not wish to limit myself to this exact construction.

Any suitable number of cartridges or bulbs may be employed and they may be ready fitted in a case so as to be inserted en bloc to" replace those used. The means for manipulating the bulbs and efiecting their discharge may be effected in any desired way.

It will be seen that I use the latent heat of evaporation of ethyl chlorid, or its homologues or admixtures of the same, by which temperatures may be produced and maintained, if necessary, below zero, Fahr., without weighty or expensive appliances.

By suitable methods it has been found that suchbodies as above can be made to cool 900 times their weight of copper one degree cent, within a very short space of time, and temperatures of minus thirty degrees cent., can be obtained.

It will be understood that the discharge outlet of the ampul or equivalent is a fine capillary tube of say =from .1 to .25 of 2). mm. bore. 4

What I claim and desire to secure by Letters Patent is 1. An appliance for cooling purposes comprising a movable carrier with means for holding flasks, ampuls or the like containing highly volatile liquid, and means for opening the flasks or ampuls consecutively by moving the carrier.

2. An appliance for cooling purposes com prising a movable carrier with means for holding flasks, ampuls or the like containing highly volatile liquid, and means for opening the flasks or ampuls consecutively by moving the carrier, said means being a holding flasks, ampuls or the like contain- I ing highl volatile liquid, means for opening the asks or ampuls consecutively by moving the carrier and an outlet from said carrier having a strainer in it.

4. An appliance for cooling purposes comprising a case, a rotary carrier in the case, means for holding flasks in the carrier, openings in the carrier to receive the ends of the flasks and means external of the carrier adapted to contact with and to break the said ends as the carrier is rotated.

In witness whereof I have hereunto set my hand in presence of two witnesses.

ALBERT HENNING.
