. 4 This invention relates to lubricant compressors, and more specifically to a large, semi-portable type for use in service stations and under similar conditions of serv ce.
Among the objects of the invention may be mentioned a detachable connection be tween the piston of the reservoir cyhnder and its guide rod. This connection may be obtained by the operator at willfor carry ng out certain manipulations such as the el1m ination of air mixed with the lubricant in the reservoir, or the lifting out of the piston itself for filling purposes.
The guiding tube for the reservoir piston may also be clamped to the cover of the reservoir when the rod is to be used for moving the device itself.
The invention also relates to a novel means for actuating the piston rod of the lubricant compressor itself by means of a pivoted foot pedal.
The single figure of the accompanying drawing illustrates, in ,longithdinal section, a double action compressor embodying these improvements.
In the embodiment of the invention selected for illustration, the movable piston of the reservoir 1 comprises a central sleeve 2 having an enlarged head 2' and threaded to receive a lock unit nut 3 for the elastic clamping against the head 2"of the clamping plates constituting the piston itself. In the wall of sleeve 2, which is bored to receive the guide rod 4:, there are formed bayonet slots-5, and guide rod 4 carries a transverse pin '6 to enter the slots when the rod 1s drawn up through the sleeve 2. This engage ment maybe obtained by a vertical entering movement followed by a movement of rotation in a horizontal plane, and will be employed when it is desired to get rid of air mixed in the lubricant. For this purose, the device is provided with a plug" 7 aving a knurled head and threaded into the bottom of the reservoir, beingprovided with a flat spot 7 Liberation of air may be eflected by unscrewing the plug slightly and operating the piston by means of rod 4 connected thereto by the bayonet slots above described.
Rod 4 terminates in through the cover 8.
a handle 9and passes It may be clamped to the cover by means of a set screw=10 havinga knurled head.
,The operating rod for the compressor piston 11 ends in a clevis 12 pivoted to a bent lever 13. This-lever is also connected to a supporting link l'pivoted on ears 15 car-'- ried by the bottom of the reservoir, and its long arm 13 is drawn toward the reservoir by coil spring 16 which, normally holds the lever in the dotted line position.
To operate the compressor, lever 13 is pushed down withone foot, which moves piston 11 down and compresses the IHbI-i-r cant below it in the annular space between its piston rod and the compression cylinder 17. The compressed lubricant may be delivered by the lateral opening 18 (pro-.
vided with a connector and flexible tube, not shown) when the pressure has risen sufficiently to push down valve 19. The c0mpression stroke ends when the piston itself makes contact with the valve, 20 yields. Upon relief of foot pressure, spring 16 draws lever'13 to its initial position while valve 19 again closes the compression cylinder and the piston, developing suction below itself, uncovers, at the upper end of its stroke, the admission ports 21.
The device shown rests on three feet .22, 22and 23, and it is provided with wheels 24 on axles journaled in feet 22 sothat when the device is in its vertical position of use, the wheels are off the ground. To move the device, rod 4 is clamped in cover 8 by means of set screW 10, and handle 9 may be and the spring used to tip the device'onto wheels 24 and move it around. g
Without further elaboration, the foregoingwill so fully explain the gist of the invention, that others may, by applying current knowledge, readily adapt the same for use under various conditions of service without eliminating certain features which may properly be said to constitute. the essential actuated by said rod, a handle formed on the outer end of said rod, means for clamping said rod against movement, fixed supports for said reservoir, and wheel supports positioned to carry the reservoir and fixed supports when the reservoir is tipped laterally by a force applied to said handle.
2. A lubricant compressor comprising a reservoir, an axially slidable rod extending out through the top of said reservoir, lubricant displacing means in said reservoir actuated by said rod, a handle formed on the outer end of said rod, means for clamping said rod against movement, fixed supports for said reservoir, wheel supports positioned to carry the reservoir and fixed supports when the reservoir is tipped laterally, and compressing mechanism housed under said reservoir between said fixed supports.
3. A lubricant compressor comprising a reservoir, a follower piston in said reservoir,
an axial guide rod for said follower piston, said guide rod being axially slidable and extending out through the top of said reservoir, a detachable connection between said follower piston and said guide rod compris ing a-bayonet slot in one and a co-operating projection in the other, said connection being capable of assembly by manipulation of the outer end of said rod, a handle formed on the outer end of said rod, means for clamping said rod against movement, fixed supports for said reservoir, wheel supports positioned to carry the reservoir and fixed supports when the reservoir is tipped laterally,
and compressing mechanism housed under sald reservoir between said fixed supports.
4. Alubricant compressor comprising a reservoir, fixed tripod supports for said reservoir, wheel support posltloned to carry "the reservoir and fix; d supports when the reservoir is tipped laterally, and compressing mechanism housedunder said reservoir between said'fixed supports.
5. A lubricant compressor comprising a reservoir, fixed supports for said reservoir, wheel supports positioned to carry the reservoir and fixed supports when the reservoir is tipped laterally, and compressing mechanism housed under said reservoir between said fixed supports.
6. A lubricant compressor comprising a compression cylinder, a piston therein, a piston rod rigid with said piston and projecting beyond said cylinder means for actuat ing the rod, and an annular check valve encircling the rod and positioned to "be unseated by the piston at the end of its stroke.
7. A lubricant compressor comprising low pressure compressing means, high pressure compressing means .fed by said low pressure compressing means, and an air vent plug for venting said low pressure means near its connection with said high pressure compressing means.
8. A lubricant compressor comprising a reservoir, high pressure compressing means supplied from said reservoir, a piston in said reservoir, an axially slidable rod extending out through an end of said reservoir, a quick detachable connection between said piston and said rod, said piston normally detached from said rod, and an air vent plug for placing that part of the reservoir on the discharge side of said piston in communication withthe atmosphere, said rod and detachable connection constituting means for operating said piston to expel air from said reservoir through said Vent plug.
