UNITED STATES PATENT OFFICE.
ROTARY AIR-COMPRESSOR.
To all whom it may concern:
Be it known that I, JAMES R. MASON, a
resident of North Versailles township, in-
the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Rotary Air-Compressors; and I do hereby declare the following to be a full, clear, and exact description thereof.
My invention relates to air compressors, and particularly to such a form of compressor as is known as the rotary type, wherein the air is compressed by rotating means.
The object of my invention is to provide a cheap, simple and efficient form of air compressor wherein the means for compressing the air will be light and efficient and will need no adjusting or regulating.
My invention consists, generally stated, in the novel arrangement, construction and combination of parts as hereinafter more specifically set forth and described and particularly pointed out in the claims.
To enable others skilled in the art to which my invention appertains to construct and use my improved rotary air compressor I will describe the same more fully, referring to the accompanying drawing, in which Figure 1 is a side elevation of my improved air compressor having the cover plate removed. Fig. 2 is a cross-sectional view of the same on the line 22, Fig. 1. Fig. 3 is a perspective view of one of the compressing means. Fig. 4 is a perspective view of the body of the compressor. Fig. 5 is a crosssectional view of the air admission port and is taken on the line 55, Fig. 1.
Like symbols of reference herein indicate like parts in each of the figures of the drawing.
As illustrated in the drawing, 1 represents the casing of my improved air compressor, and said casing is circular in form and consists of an end wall 2 and a circular flange portion 3. The material forming the casing 1 is preferably of brass or other like material and the inner face 4 of the circular flange 3 is finished in order to provide a smooth and even surface. A cover 5 is adapted to be placed upon the outer edge 3 of the circular flange 3, and said cover is held in place by means of screws 6 fitting through the same and into said flange.
The end wall 2 of the casing 1 and the cover 5 are each provided with a hole 7 Specification of Letters Patent.
Application filed. September 25, 1911.

Serial No. 651,237
therein for forming a bearing for the body portion 8, as hereinafter described. These holes 7 are situated directly opposite one another and are at a point slightly distant from the center of the cover 5 and end wall 2 so that the body portion 8 in its rotation in the casing 1 will revolve at a position off the center of said wall. and cover.
The body 8 is provided with arced portions 9 at equal intervals throughout its periphery and between each of the same is a flat portion 10 and a curved slot 11, which extends the entire width of the same, while a lug 12 is formed at the center'of said body and on. each side of the same to provide a means of rotation by fitting into the holes 7 in the end wall 2 of the casing 1 and the cover 5. The lugs 12 are adapted to extend a slight distance outward from the outer faces of the end wall 2 and cover 5 and have a hole 13 extending through the same and the body 8 to provide for attachment to a motor or other source of power.
The curved slots 11 are each provided with a plate 14 which is formed from fiber or other light material and has an enlarged end 15 for fitting into the slot 11 in the body 8,
and said plate is slightly longer than the flat portion 10, while the other end 16 of the same is curved to provide a close contact with the inner face 4 of the flange 3, as hereinafter described. Secured to the plate 14 and adapted to extend beyond the arced portion 9 immediately beyond the same is a wing 17 which is formed of sheet material such as tin, aluminum, etc, and such wing is curved in shape and adapted to conform to different positions of said plate. The plate 14 is adapted to be movable in the slots 11, and in certain positions of the body 8 extend outward from the flat portion 10, as shown in Fig. 1.
At the bottom of the casing 1 is an arm 18 which may be of any length, and such arm is used merely to prevent rotation of the casing 1 when the compressor is attached to the shaft of a motor for operation. This arm may be of any suitable shape and will rest against the table, or the compressor may be mounted on a pedestal and secured to the table or stand, as desired. Above the arm 18 and in the flange 3 of the casing 1 is an air inlet port 19 which may be either a hole drilled in the side of the same or may be provided with a regulating means such closed by abutting against said flange.
as shown in Figs. 1 and 5. In such a case the hole l9 is drilledthrough the flange, and another hole 20 larger in diameter than said first named hole is drilled and tapped in the same and extends about three-fourths of the,
and such thread extends about half way up the outer surface of said regulator while the other portion is provided with a nurling 23 foradjusting the same with the-fingers. A number of holes 23 are drilled through the regulator 22 and are opposite the flange 21 so that when said regulator is screwed tightly into the hole 20 theholes 23 age n the other side of the flange 3 is an exhaust port 24 into which is fitted a nipple 25 to provide a means for exhausting the compressed air from thecompressor, and said nipple is so formed as to. admit of a hose being attached to the same for transmitting the same to any place desired.
The operation of my improved rotary air' compressor is as follows:The compressor is mounted on the motor shaft, as described, and the motor is then set in motion so that the body 8 in the casing 1 will be caused to rotate in the direction of the arrow, while said casing will be prevented from revolving bythe arm 18 resting against the table on which the motor is mounted. The air is drawn into the interior of the casing 1 through the openings 23 in the regulator 22, and the amount of the same is controlled by the position ofsaid regulator which is adjusted by screwing "said regulator into the hole 20 by the knurled portion'23 thereon, and the air entering the casing 1 through the port 19 is regulated by the distance be tween said regulator and the flange 21, as the air before entering the opening 19 must pass between the end of said regulator and said flange. The body 1 being rotatable off the center ofthe casing 1, more space will beprovided at one side of said body than at the other, and as the air is admitted at atmospheric pressure on said larger side, the'pockets formed by the plates 14: and the wings 17 will be decreased in size as they pass the exhaust port 24, so that the aircollected at atmospheric pressure at the enlarged side of said casing will be compressed and will pass outward through said port and may be piped toany point desired; The
- My improved rotary air compressor may be used to great' advantage in dentistry work, where it is desired to center a heat at any particular point, and the fuel, such as gas, may be mixed with the compressed air from such compressor, and the blast therefront will provide a heat of very high temperature, while 5 the compressed air may be used in a number of ways, and. its degree of compression will depend to a greater or lesser extent onthe speed of the motor operating the same, and by the position of the regulator in the admission port.
Various changes and modifications in the design and construction of myv improved rotary air compressor may be resorted to with out departing from the spirit of the invention or sacrificing any of its advantages.
What Iclaim as my invention and desire to secure by Letters Patent is l I 1. A fluid compressor comprising a casing having inlet and exhaust ports, a rotating member mounted eccentrically in said casing, a series of plates pivoted at one of their ends to said member and adapted to engage by their other ends with the innerwall of said casing, and spring wings on said plates engaging with said wall and adapted to form a space between the same and said plates for compressing the fluid between said plates and wings. v 2. A fluidcom-pressor comprising a casing havinginlet and exhaust ports, a rotating member mounted eccentrically in said casing, a-series of plates pivoted at one of their ends to said member and adapted to" iive cents each, by addressing the (Commissioner of Patents, 7 Washington, D. G.
