GEORGE T. KENNEDY, OF CALGARY, ALBERTA, CANADA.
AIR-COMPRESSOR.
Specification of Letters Patent.
Application filed February 7, 1916. Serial No. 76,736 i 1 To all whom it may concern:
,Be it known that I, Gnonen T. KENNEDY, a subject of the King of Great Britain, residing at Calgary, in the Province of Alberta and Dominion of Canada, have -in-- vented new and useful Improvements in Air-Compressors, of which the following is a specification.
This invention relates to improvements in air compressors and has particular application to a centrifugal compressor.
In carrying out the present invention, it is my purpose to provide a centrifugal air' compressor which will embody in its construction an inner stationary cylinder formed with valve controlled ports and an outer revolving cylinder surrounding the stationary cylinder and having slots formed therein and equipped with outwardly projecting tangentiallycurved blades adapted to draw the air through the slots and force the same through the valved ports of the stationary cylinder into the latter so that the compressed air may be taken from the inner cylinder. 1 v I It is also my purpose to provideacentrifugal air compressor which will embody comparatively few parts and these so arranged and correlated as to reduce the pos "sibility of derangement to a minimum and wherein the parts of the compressor may be lubricated and cooled.
With the above and other objects in view, the invention consists in the construction, combination and arrangement of parts hereinafter set forth in and falling within the scope of the claims' In the accompanying drawings;
Figure 1 is a view inelevation of an air designates a stationary cylinder formed with longitudinally extending passages 2 spaced apart around the cylinder and adapted to receive a cooling liquid. Formed in the outer surface of the cylinder 1 adjacent to the respective ends thereof are annular grooves or raceways 3. While formed in the' cylinder between the grooves 3 are a plurality of ports 4 and arranged in each port 4 is an inwardly opening check valve fi which permits air or other fluid to flow through the ports and into the cylinder, but prevents Y the return of such fluid through'the ports. Surrounding thelcylinder 1 and adapted to rotate thereabout is a. cylinder 6 of less length than the cylinder 1 and formed in the inner wall of the cylinder 6 adjacent to the respective ends thereof and coinciding with the grooves or raceways 3 are grooves or raceways 7 and disposed within these alining raceways are ball bearings acting toreduee the friction between the revolving H cylinder and the stationary cylinder in the rotation of thecylinder 6. Formed in the Patented Aug". 28, 1917.
In practice, the cylinder 5 is rotated about the stationary cylinder and in the rotation of the cylinder 6 the blades 10 act to draw air toward the slots'8 and'compress such air to force the same through the valved ports 4 and into the stationary cylinder whence such air may be conveyed to a suitable receiver.
/Vhile l have herein shown and described the preferred form of my invention by way of illustration, 1 Wish it to be understood that I do not limit or confine myself to the precise details of construction herein de scribed and delineated, as modification and variation may be made within the scope of the claims and without departing from the spirit of the invention.
I claim:
I. In a centrijin 'al air compressor, a stationary cylinder; formed with valved ports, a revolving cylinder surrounding said stationary cylinderand formed with longitudinal slots spaced apart about said revolving cylinder, and blades secured to corresponding edge walls of said slots respectively and projecting outwardly from such revolving cylinder substantially at a tan gent thereto and curved in cross section whereby air may be drawn into said slots and compressed through said ports into said stationarv cylinder in the movement of the revolving cylinder.
2. In a centrifugal air compressor, a stationary. cylinder formed with valved ports, a revolving cylinder surrounding said stationary cylinder and formed with longitudinal slots spaced apart about said revolving cylinder, blades secured to corresponding edge Walls of said slots respectively and projecting ouhvardly from such revolving cylinder substantially at a tangent thereto and curved in cross section whereby air may be drawn into said slots and compressed through said ports into said stationary cylinder in the movement of the revolving cylinder, plates closing the ends of said revolving cylinder. and a casing inclosing said cylinder and secured to said end plates and formed in such manner that air may be drawn therelhrougl'i.
In a. centrifugal air compressor, a stationary cylinder formed with valved ports, a revolving cylinder surrounding said stationary cylinder and formed with longitudinal slots spaced apart about said revolving cylinder, and blades secured to corresponding edge walls of said slots respectively and projecting outwardly from such revolving cylinder substantially at a tangent thereto and curved in cross section whereby air maybe drawn into said slots and co1npressed through said ports into said stationary cylinder in the movement of the revol ring cylinder, said stationary cylinder being formed with longitudinally extending passages through which a cooling fluid may be passed.
In testimony whereof I aliix my signature in presence of two Witnesses.
