REFRIGERATING MACHINE Original Filed Oct. 25, 1927 2 Shoots-Shut 2 l 55. Gator vices and particularly to animprovement in Patented Aug. 12, 1930 UNITED STATES imsmus M. HVID, or CHICAGO, ILLINOIS REFRIGERATING MACHINE Application filed October 25, 1927, Seria1 no. 228,511. nenewea January 6, 1930;
My invention relates to refrigerating dea detail of construction of the machine disclosed in my copending application, Serial 5 No. 228,510 filed of even date herewith.
An object of the construction here disclosed is to provide for economical construction and simple and effective assembly of the parts thereof.
In order to enable'the use so faraspossible, of castings in the constructionoi the principal parts of an ice machine, I have" designed a casing construction composed of three parts which may bev cast in the proper shape and machined to provide abutting tongueand-groovefluid-tight joints. Inasmuch as;
these parts are intended to contain thehigh pressure gas, the construction should besuch that gas leakage throughout'the expected life of the device is certainly avoided. To
that end, I provide a construction composed of three parts, adapted to be pulled into tight engagement by a plurality of bolts-and when so positioned, to be fluid tightthereafter;
Another object of the invention issto include simple means for mounting the motor supporting frame on the'c'asing, such means providing for removal andreplacement of drawings, in which:
the motor without interfering in any manner' with the remainder of the assembly,
' The invention will be morereadily understood by reference to the accompanying Fig. 1 is-a verticalsectional view through a casing construction for icemachines, arranged in accordance w th my invention; and
of Fig. 1. i i a i In the drawings I have illustrated the 1m- Fig. 2 is asectional. view on the" line 2-2' portant features of the invention, eliminating details that arenot herein claimed. It-will be observed that the parts comprising the high pressurechambers include'an upper,
hemispherical casting, 10, a lower hemisphen ical casting, 11, and an intermediate horizontally disposed casting, 12. i The top wall 13 ofthe upper casing member lOisgenerally flat and horizontally disposed, providing a a convenient seat'for the legs, 14 o fla' motor frame, not shown." Thus'the motor and its mounting may. be readily applied and removed withoutlinterfering withfthe remainderfof the assembly. i
The method of constructing 'and joining all'three casing parts, 10, 11, 12 constitutes a dl'stlnctadvanc'e in this art. The desired remember 10; Lead orother metal gaskets are inserted inthe respective grooves and a force lapplied'throughtheears l9, 20, and bolt,
'21, tends to pull the parts towardeachother.
Due to tlieshapefof the groove 17, the clamp ing force tends to seal'all three. of the con- 3 tacting 'part's. By providing a relativelylarge number of clamping bolts, as shown in Fig; 2, I amabletosecure a high; degreebf clamping pressure which when evenlyj'apconstruction, inasmuch as the chamber is intended I to contain high prsesure refrigerating gas. The chambers 22, 23, contain high-pressure gas, whereas the chamber 24is l i d results in aipermanent'seal between th'e'part's, This is essential in ice machine low pressure and an efficient seal must be provided therebetween.
Another important point is'that by the design here disclosed, I am able to'employ metal castings instead of inetalstampings, with greatly reduced cost'and without a 'substan tial increase in weight. w
Various modifications may be made in the design and construction herein illustrated e within the skill of the mechanic, and I do not wish to be limited except as indicated in V the {appended claims e i I claim v 1. Inan ice machine, the combination of upper and lower casing "members, each of gen erally hemispherical shape, and a separate intermediate wall, said upper and lower members having angularly spaced ears, said three vpart-shaving abutting, cooperating grooves and flanges, gaskets between the abutting portions, and bolts enga ing the respective lugs and adapted to pull t e three parts into gastight abutting relation.
2. In combination, upper and lower casing members and a separate, intermediate wall member having an annular flange and an annular groove, the upper member having the annular groove adapted to cooperate with the flange on the intermediate member, and the lower member cooperating with the groove in said intermediate member, lugs on said upper and lower members, and bolts engaging the lugs and adapted to pull the upper and lower members toward each other and to join the respectiveflanges and grooves of the three parts to provide a fluid tight connection.
3. In combination, upper and lower casing members of generally hemispherical form and an intermediate member serving to divide the s ace within said first members into two cham ers, said three members being composed of cast material, said three members having cooperating flanges and grooves, apertured lugs on said upper and lower members, and bolts engaging the lugs and adapted to pull the parts together to form a fluid tight connection betweenthe three parts.
4. In an ice machine, the combination of upper and lower members providing a high ressure chamber, a'wall dividing said chamers, said intermediate wall having an annu larflange and a peripheral groove, said upper member having an annular groove for engagement by the annular flange, and said lower member having its marginal portion shaped to engage the annular groove in said intermediate wall, and means engaging the upper and lower members and adapted to pull the same together and to confine the intermediate wall in gas-tight relation thereto.
Intestimony whereof I have aflixed my signature.
