ICE-MACHINE.
SPECIFICATION forming part of Letters Patent No. 679,696, dated July 30, 1901.
Application filed March 20, 1901. Serial No. 52,079. (No model.)
To @ZZ whom t may concern:
Beit known that I, JOHN H. J. HAINEs, of the city and State of New York, have invented a new and useful Ice-Machine,which is fully set forth in the following specification.
This invention relates to the construction of ice-machines, and more particularly to that class of ice-machines wherein low temperature is produced by means of a hygroscopic substance (such as sulfuric acid) and a vacuum. This method, while practical and effective, has not up to the present time, so far as I am aware, been brought within commercially economic limits, and the object of my invention is to provide an apparatus wherein ice can be manufactured or low temperatures produced for other purposes in an economical manner.
The improvements embraced in the invention can Vbest be explained in connection with the accompanying drawings, wherein- Figure l is an elevation of an apparatus constructed in accordance with the invention. Fig. 2 is a top plan view thereof, and Fig. 3 is a vertical section of the valve controlling communication between the element-s of the system. y
In the drawings, A represents the cylinder of avacuum-pump, and nits piston-rod. The pump may be of ordinary construction and operated in any suitable Way. As shown, the operating means consist of a hand-crank C, attached to a fly-wheel D, and a pitman E, connected at its upper end to the pump-lever F, (pivoted atf,) and at its lower end connected to wheel D at G. (See dotted lines, Fig. l.)
H represents the vessel containing the sulfuric acid or other material which has a strong avidity for moisture. Vithin this vessel is an agitator, shown as formed of perforated plates 7L, attached to an upright shaft I. At its upper end this shaft has a hori- Zontal arm or pin z', which passes freely through a slot e in pitman E. The vertical is shown in Fig. 2.
centrically connected t0 wheel D, has an oscillatory movement as Well as a reciprocatory movement. The oscillations of pitlnan E will consequently impart au oscillatory movement to the agitator h. The agitator may of course be of any convenient description.
K represents the refrigeration or ice chamber.` It is preferably formed in two parts united in a horizontal plane by screw-clamps 71; or otherwise, so that the upper part can be removed for inserting and removing the vessel L, in which the ice is to be formed. This vessel is herein shown as a carafe, such as is used in restaurants, the entire apparatusbeing of a form and description suitable for freezing water in such vessels. The forms and details generally may obviously be modified according to the specific use for which the machine is designed.
Between the outer vessel K and inner vessel L is a space m. In the operation of the machine a vacuum is formedin this space, it being found that the production of freezing temperature in vessel L is thereby greatly expedited. Vessel L is thus insulated by a vacuum. The cock or valve N controls communication between the pump-cylinder and the vessels or chambers H, L, and m. The casing of valve N has three ports. Port n leads by pipe O to the pump-cylinder, port n.2 leads through plug O2 to the Vessel H, and port n3 leads by pipe O to vessel K-that is tol say, to the vacuum-space m between vessels K and L. The ice chamber or vessel L leads by pipe O3, inclosed in pipe O, and by passage n4 to port n2. Consequently the vessel H and icechamber L are simultaneously connected with and disconnected from the pump.
In the position of the parts shown in Fig. 8 the vacuum-space m within Vessel K is in communication with the pump-cylinder by way of pipe O', port n3, groove n in the valveport n', and pipe O. A few strokes of the pump-piston serve to exhaust the air from space m. Valve-handle N'l is then turned through an arc of ninety degrees, which puts ports n n2 into communication through the hole N2 through Valve N. The vessels H and L are thus simultaneously put into communi- IOO 1. In an ice-machine the combination of the ice-chamber, a vacuum-chamberinclosing the same,y a vessel separate from said vacuumchamber, for containing the absorbing material, an exhaust-pump, and means for putting said pump in communication with said icechamber, vacuum -chamber, and absorbing vessel.
2. The combination of the ice-chamber, the vacuum-chamber surrounding the latter, the absorbing vessel the latter being in free communication with the ice-chamber, the exhaust-pum p, and means for putting said pump alternately in communication with said vacuum-chamber, and with said ice-chamber and absorbing vessel.
3. The combination of the eXl1aust-pump, 2 5
the ice-chamber, the vacuum-chamber surrounding the latter, the absorbing vessel, and the three-way valve having a port communieating with the pump, a second port communicating with the said vacuum-chamber, and a third port communicating with the icechamber and absorbing-chamber.
l. The combination with the exhaust-pump, absorbing-chamber,icechamber and pipe connections between said chambers and pump, of a vacuum-chamber inclosing the ice-chamber, and detachably connected with piping leading to said pump, and means for connecting the latter alternately to said vacuumchamber, and with said ice-chamber and absorbing-chamber.
In testimony whereof I have signed this specification in the presence of tWo subscribing witnesses.
