CHARLES C. SPREEN, OF DETROIT, MICHIGAN, ASSIGNOR TO KELVINATOR CORPORA- TIO'N, OF DETROIT, MICHIGAN, A CORPORATION OF DELAWARE oomranssoa.
Application filed July 26, 1923. Serial No. 653,968.
7 To all whom it may concerns Be it known that I, Crmamts C. SPREEN, a citizen of the United States, residin at Detroit, in the county of Wayne and tate of Michigan, have invented a certain new and useful Improvement in Compressors, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings.
The Widespread use of artificial refrigeration in homes and small stores has necessitated the developement of a unit embodying many refinements not present in the large commercial installations theretofore inuse. My invention is designed to further this development by the production of a compressor superior, at least" for use in such units, to any compressor heretofore known, particularly in reducing the attention required and in further preventing the escape of refrigerant from the refrigerating system. In the drawings accompanying this specification and forming a part thereof I have shown, for purposes of illus- 2 tration, one form which myinvention may assume and in the single figure of these drawings have shown a vertical section of this improved compressor.
The compressor described in these draw ings comprises a crank case 11 arranged to support a compression cylinder 12 in which is located a suitable piston 13 connected b means of a pitman 14 with a crank sha 15 which: lies entirely within the crank case 11' and is. supported therefrom by means of bearings 16 and 17 carried by the crank case 11 and also lying entirely therewithin.
I have shown this crank case 11 as provided also interiorly thereof with a third bearing 18 arranged to support one end of a trans mission shaft 19 which carries a pinion 20 meshing with a cooperating gear 21 carried by the crank shaft 15 and extends exteriorly of the crank case 11 where it is additionally 4:5 supported in any suitable manner and is arranged to be operated by any means suitable for operating the compressor. Iihave shown this transmission shaft 19 as emmerging from the crank case 11 through so an opening 22 in a plate 23 secured to the crankcase 11 by suitable bolts 24 and clamping between itself and the crank case 11 one end of a substantially tubular sylphon 25 the other end of which is securely 65 sealed to a ring 26 which is held in tight the single opening through which the transmission shaft 19 emerges, that this single opening is tightly sealed against the escape of any refrigerant which-maycreep into the crank case 11 from-the cylinder 12 by the sylphon 25 sealed at one end directly to the crank case 11 and at the other end to the ring 26 which is tightly sealed by the sprin 28 to the shoulder 27 of the shaft 19, an that the construction herein shown accord- .inglyprovides a compressor in which esca e of the refrigerant is practically impossib e. It will also be apparent that the positioning of the reduction gearing entirely within the crank case 11 entirely revents injury to the operator from accidental contact with the gears while the compressor is in operation and, in addition, by surrounding the gearing with an oil tight shield, permits the application to the gearing of the large quantity of oil necessary to eliminate noise and wear and which, because of excessive spattering, could not be applied were the gears not so enclosed.
It will also be apparent to those skilled in .the art that the construction herein shown may be variously modified without departing from the spirit of my invention or sacrificing the advantages thereof and it will therefore be understood that the disclosure herein is illustrative only and that my invention is not limited thereto.
I claim:
1. A compressor comprising at least one cylinder, a crank case hermetically connected thereto and having but one additional operative opening and divided into a crank chamber and a gear chamber by a wall hav-v ing a single operative, aperture, a pair of bearings carried by said crank case one interiorly of said crank chamber and the other tightly sealed within said aperture, a crank no shaft mounted in said bearings and lying entirely Within said crank case, a third bearing carried by said crank case interiorly of said gear chamber, a transmission shaft par tially supported in said bearing and lying partly within and partly without said gear chamber and entering said gear, chamber through said single operative opening in said crank case, co-operating gears carried by said crank shaft and said transmission shaft and lying entirely within said gear chamber, and a seal hermetically sealing the space between said transmission shaft and said opening.
2. A compressor comprising a crank case divided into a crank chamber and a gear chamber by a wall having a single operative aperture, a crank shaft lying entirely within said crank case, bearings, lying one entirely within said crank chamber and one tightly sealed within said aperture, supporting said crank shaftfrom said crank case, a transmission shaft lying partly within and partly without said gear chamber, a bearing lying entirely within said gear chamber and partially supporting said transmission shaft from said crank case, means hermetically sealing any space between said transmission shaft and the edges of the opening through nseaooe which said transmission shaft enters said gear chamber, and gearing lying entirely within said gear chamber connecting said crank shaft and. said transmission shaft.
3. A compressor comprising a crank case divided into a crank chamber and a transmission chamber by a wall having but a single operative aperture, a crank shaft lying entirely within'said crank case, bearings, lying one entirely within said crank chamber and one tightly fitted within said aperture, supporting said crank shaft from said crank case, a transmission shaft lying partly Within and partly Without said transmission chamber, a bearing lying entirely Within said transmission chamber and partially supporting said transmission shaft from said crank case, means hermetically sealing any space between said transmission shaft and the edges of the opening through which said transmission shaft enters said transmission chamber, and transmission'mechanism lying entirely within said transmission chamber connecting said crank shaft and said transmission shaft.
In testimony whereof, I hereunto aflix my signature.
CHARLES C. SPREEN.
