FREDERICK AUGUST GERLING, OF SILVER CITY, IDAHO, ASSIGNOR OF ONE-FOURTH TO DANIEL DALE LONG. AND ONEFOURTI-Lf TO RICHARD RICHARDSON, BOTH OF BOISE,

IDAHO.

REVOLVING AIR GOMPTi-ESSOR.

To all whom it may concern:

Be it known that I, Fnnnnnrox AUGUST GERLING, a citizen of the United States, residing at Silver City, in the county of Owyhee and State of Idaho, have invented a new and useful Revolving Air Compressor, of which the following is a specification.

This invention relates to an improved revolving air compressor, and the object thereof is to provide a balanced machine which will require a small amount of power to operate so as to compress and store air under pressure for various uses.

A further object of the invention is to provide a revolving air compressor having novel actuating means, capable of being automatically operated during the rotation of the machine, and so constructed as to regulate the weight of a plurality of pendulums designed to actuate the compressors or air pumps so that the degree of pressure may be varied as to the capac ty of the machine, and in addltion, to provide improved .means for lubricating the parts during the operation.

'which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that within the scope of what is claimed, changes in the precise embodiment of the invention shown can be made without departing from the spirit of the invention.

Serial no. 342,427.

Referring to the drawings in detail, in which like reference characters designate corresponding parts throughout the several views, my improved revolving air compressor, is shown as comprising a base 10 upon which is supported any number of alined bearings 11 vertically arranged and designed to rotatably receive in their upper ends, a horizontal shaft 12, suitable anti-friction means consisting of rollers, balls or the like, being provided if desired between the shaft and the bearin 's thereof; The shaft is adapted to be driven in any suitable manner from a prime mover, such as a gasoline en gine, or a steam engine; The opposite end of the shaft which is hollowed out longitudinally as indicated at 14, is connected to a stationary pipe 15 through a medium of a swivel or coupling 16, said pipe 15 leading to a suitable store chamber for compressed air, which is adapted to be supplied and compressed therein by the device constituting the subject matter of the present invention.

The shaft 12 is provided with an enlargement or double wall formation, the shaft being hollowed axially as indicated at 14: in the manner previously described and provided with a concentric wall 17 forming an annular chamber 18 extending over a considerable portion of the shaft 12 and adapted. to receive oil for lubricating purposes. The axial opening of the shaft and the chamber 18 are noncommunicating, and the oil contained in the chamber 18 is adapted to be supplied to the working parts of the machine, in a manner to be hereinafter more fully set forth.

'Extending from the shaft 12, there are a series of radiating arms 19, which are arranged in any suitable manner in order to secure an even balance, the number of arms thereon depending .upon the size or diameter of the machine, for the purpose to be explained. The arms 19 are provided with cross members 20 at their outer ends serving to pivotally support pendulums 21, which are pivoted thereto in any suitable manner as by means of screws 22 forming pivots engaged axially in the cross members or arms 20 extending longitudinally of the axis of the machine. The pendulums .21 are formed at their inner ends with rings 23 which encircle the shaft, so that the axis of the shaft and the axis of the rings coincide.

The rings 23 are considerably weighted or made heavy so that by reason of the leverage produced, the rings will act by gravity during the rotation of the shaft together with the arms 19, and cause the rings in moving downwardly and upwardly to operate the pumps.

Mounted at rightvangles on the .arms 19, are the compressors consisting of alined cylinders 2% having pistons therein connected to work in unison or in tandem in the manner of double acting engine, the piston rod being indicated'at 25. As the arms are disposed in staggered relation axially of the shaft and'uniformly spaced apart equi-distantly of the length of the machine, an even balance will be secured. Each pendulum has connection with a piston rod as indicated at 26, so as to actuate the latter upon actuation of the pendulum fordrawing air into the cylinders through the inlets 27 and discharging the same through the outlets 28, said inlets and outlets being controlled in any desired manner by means of check valves preferably working in opposite directions so that th c air may be forced through pipes 29 extended radially along side the arms 19, and through the walls leading to the hollow portion 14: of the shaft so as to be carried off and stored under pressure, as previouslyset forth. In Figure l of the drawings the upper pendulum is shown in a neutral position, the one at the left is shown in a compressing position when the pendulum has dropped by g'avity after passing over the dead center in which. the vertical or upper pendulum is shown disposed, the lower pendulum is also shown in a neutral position in slotted lines and in dotted lines after immediately passing over the dead center and finally dropping, when in position shown at the right in Figure l to reciprocate the piston rod and its pistons or plungers in the opposite direction, such as takes place, during a complete cycle.

In order to lubricate the parts, pipes 30 extend radially from the chamber 18, and have connection with the various cylinders through the branches 31, as through the me dium of an oil pump 32, so that the distribution of the oil insured for lubricating the various parts during the working thereof.

7 In order to vary the momentum imparted to the pendulums by the rings23, the latter may be weightedby means of balls 33 as clearly shown inFigure l of the drawings, or as shown in Figures 6 and 7, the ring may be provided with traekways or grooves 34, receiving the wheels 35 of a weighted car 36, so that varying the weight of the car, the momentum of the pendulum can be varied. In this way, theweight acting on the pistons for the purpose ofreciprocating the same and actuating the an compressors as the machine revolves may be varied in accordance with the desired capacity.

Also. since the cylinders 24. are mounted on cross arms 37, the pressure may bevaried by varying the proportion of the distance between the cross arms and the extremities of the arms 19, and the axis by varying the positions of the cross arms 37 and varying the weight ofthe pendulums, as heretofore set forth. Also, it is to'be understood that the pendulum rings are made sufficiently heavy to give the desired pressure, the pendulums causing the actuation of the air cylinders or compressors as the machine revolves, owing to the continuous dropping ofthe pendulums as they approach a point at opposite sides of the vertical center in the direction in which the machine revolves. f

It is also 7 to be understood that, the weighted means consisting ofthe ball 33 or of the wheel car 36, is adapted to revolve around the ring during the rotation of the machine including the shaft and arms, by the centrifugal action produced, and it is also apparent that this action will help to oscillate the pendulums in addition to the action of gravity caused by their weights;
