R. BERRENBERG. APPARATUS FOR PRODUCING HIGH PRESSURES.
APPLICATION FILED FEB. I0, 1917.
Patented July 13, 1920.
Rgfmvntar r *X'Wik REENOLD BEBRENBERG, 011 BOSTON, MASSACHUSETTS.
Specification of Letters Patent.
application filed. February 10, 1917. Serial No. 147,915.
To all whom it may concern.-
Be it known that T, Rumors Bnnnnnenne, a citizen of the United States, residing at Boston, in the county of Suffolk. and State of Massachusetts, have invented a new and useful Improvement in Apparatus for Producing High Pressures, lowing is a specification.
The present invention relates to apparatus for producing high pressures, and more particularly to such apparatus for use 1n motor cars to pump the tires thereof full of air.
The object of the present invention is to produce an apparatus of the type hereinbefore referred to which will produce high pressures in an economic manner and which will pump air into pneumatic tires wlthout liability of oil or other lubricant used in the apparatus entering with the air into the tires.
To the accomplishment of this object and such others as may hereinafter appear, the various features of the present invention consist in certain devices, combinations and arrangements of parts fully set forth hereinafter, the advantages of which will be readily understood by those skilled in the art.
The various features of the present invention will be readily understood from an inspection of the accompanying drawings, in which,
Figure 1. is a detail inside elevation, partly in section, of the apparatus;
Fig. 2 is a detail in front elevation, partly in pkentral, vertical section, of the apparatus; an
Fig. 3 is a sectional detail of the adjusting means for the blade actuating ring.
Tn-the illustrated embodiment of the invention an air-ti ht tank is mounted on a suitable base 2. ll/llounted on one end wall of the tank 1 is a casing 3 for a rotary pump. This pump comprises a carrier 4 provided with a series of blades or pistons 5 loosely mounted in slots 6 formed in the carrier i. The carrier 4 is arranged to fit the upper part of the casing 3 and leave a chamber 7 between the carrier and casing in the lower part of the casing.
The carrier 4: is rotated shaft 8 which extends throug a stuffing box 9 on the tank 1 and which is driven from some suitable source of power. During the rotation of the carrier, the blades 5 are of which the fol-v b a horizontal pushed outwardly in the slots 6 to contact with the casing 3 by a ring 10 which surrounds the shaft 8' and a roll 11 loosely mounted on a stud 12 secured to the casing. The casing 3 is provided with a slot 13 to permit the adjustment of the roll 11 and thus change the position of the ring 10.
The casing 3 is provided with an inlet port 14 and an outlet port 15. The port 14: communicates with the chamber 7 into whlch the air to be compressed is supplied by a horizontal pipe 16 provided with a check valve 17. The inlet port 14 is located a substantial distance below the horizontal plane passing through the axis of the shaft 8, whereas the upper edge of the outlet port 15 is substantially coincident with said plane. l/Vith this construction the air is drawn through the port it at a time when the space inclosed between the blades 5 nearest the port 142 is increasing in size. When the bucket formed by the blades between which the air is trapped passes the lowest point in the casing the space within the bucket decreases in size thus causing the air in the bucket to be compressed. The compressed air is discharged through the outlet port 15 into a vertical riser 18 which conducts the air to the tank 1.
Tn order to seal the internal parts of the pump and thus prevent leakage of air either through the casing or from one bucket to another the tank 1 is provided with a lubricant, such as glycerin, or oil, to a depth indicated by the line 19 which is below the upper end of the riser 18. This lubricant is subjected to the pressure of the air discharged into the tank 1 and is forced through a screen 20 and a needle hole 21 into the inlet port or casing 3. This lubricant entering the casing efiectively seals the space between the blades and the casing and thus prevents the leakfife of air from one bucket to another. oreover the air pressure acting on the lubricant forces the flat end walls of the casing against the edge faces of the rotating blades, thereby tightening the joints between the blades and the end walls. The roof of the tank or reservoir 1 is concaved and the riser 18 is arranged to discharge the air and accumulations of lubricant directly against the concaved roof. This. construction causes the lubricant to strike the arched roof with such force as to separate it from the air which is deflected in its course by the curved roof. The air is Patented July 13, 1920 thus caused to circulate across an outlet 22 in the roof until the air is again deflected by the wall 23 into the air-storage part of the tank. The stored air is drawn as needed through the outlet 22 free from traces of the lubricant thus making the present invention particularly useful in filling pneumatic tiress When the pump is not in use the lubricant gradually 'fills the inlet port 14 and the pipe 16 back to the check valve 17. When the pump is rotated this accumulation of lubricant is discharged from the riser 18 and spattered against the arched roof. The lubricant is thus separated from the air and returned to the body of lubricant in the reservoir. r
What is claimed as new, is:
1. An apparatus for producing high pressures, having, in combination, a tank for storing lubricant and compressed air, said tank having an arched roofand an outlet formed therein, an air compressor immersed in the lubricant in said tank, a discharge pipe for the compressed air and accumulations of lubricant opening into the tank above the level of the lubricant therein and adapted to discharge directly against the arched roof at one side of the outlet therein,
- whereby the lubricant is separated from the air, substantially as described.
2. An apparatus for producing high pressures, having, in combination, a rotor provided with a series of radially disposed slidable blades providing buckets between said blades, a casing in which said rotor is sures, having, in combination, a rotor blades while the buckets are in communication with said inlet port, and means cooperating with said casing to supply lubricant to said restricted aperture and to conduct the lubricant externally of said casing from said outlet port to said aperture. I
3. An apparatus for producing high presprovided with a series of radially disposed slidable blades providing buckets between said blades, a casing in which said rotor and said blades are rotatably mounted, said casing being provided with inlet and outlet ports, and having a chamber connecting said ports,
, which chamber is traversed by said buckets,
a lubricant tank into which the outlet from said casing discharges at a point above the level of the lubricant in said tank, said casing being immersed in the lubricant in said tank and having a restricted inlet admitting lubricant into each bucket when the same is in communication with said inlet port, whereby the body of the lubricant in said tank will be subjected to the pressure produced in said apparatus, and the lubricant will be forced through said restricted opening by said pressure.
