(l.-137--'204) This invention relates to mechanism to abstract a liquid, such as water, from a gas, such as compressed air.

In the operation of air-compressing mechanismssuch as air brakes, water collects and interferes with the functioning of the mechanism, thereby presenting a problem I of disposal of the water without loss of compressed air.

One of my objects is to provide improved mechanism to automatically dispose of 'said water without loss of air or gas, that is compact and uses a minimum number of parts. g

Another object is to provide an improved construction that enables a direct and simple connection with an air reservoir, and an arrangement that permits liquid to flow directly downward from the time it enters my mechanism until it reaches a point ready for discharge.

The foregoing and other objects which will appear as the nature of the invention is better understood, may be accomplished by a construction, combination and arrangement such as is disclosed by the drawings. The nature of the invention is such as to render it susceptible to various changes and modifications, and, therefore, I

bottom closure plug 58 which screw-threadedly connects am not to be limited to the construction disclosed by the drawings nor'to the particular parts described in the specification; but am entitled to all such changes therefrom-as fall within the scope of my claim.

In the drawings:

Figure 1 is a vertical, sectional view of my water abstracting mechanism, shown enlarged, and with the valve in closed position.

anism. This neck 16 has a port 17 extending therethrough which communicates with an interior chamber 22 of'said head portion 14. The lower portion of said head 14 is interiorlyscrew-threaded as at 18 to connect with the screw-threaded upper portion 20 of said main body 10.

Within said chamber 22 is spacer apparatus which has a sleeve 23 and a collar 24' on which said sleeve 23 rests and which in turn rests on the top surface of said main body 10. A filter 25 rests on a shoulder 26 formed by making a recess in said sleeve 23, and said filter is held inposition by a retainer 27, forming part of said spacer apparatus, and which rests on the top surface of said sleeve 23. This filter 25 may be made of fine mesh, brass wire fabric or other suitable material. Said collar 24 has holes 28 therein and at the center is a neck portion 29 having a hole 30 therethrough to slidably receivea shaft 36, later described.

{Within said main body 12 is a float chamber 32 in communication with said-holes .128, and in which a :fioat 34 is movably housed, which floatds-shown as 1a.hol101w, metal :b,a ll ialthoughit :could .be imade'of other suitable materials. said float ;34.-;is mounted on :said shaft 3.6, which ,latterhasa reduced'lowerqend 37 r to permit ,liquid to sflow beyond .it; when -in--,open position, It is movable in said hole 30 as ,saiddloat .is raised'or lowered inwsai'd chamber 32. This ,float irestsh on a ,collar 38' attached to ,said shaft 36 .andds held in predetermined position on saidshaft with-the ,aido fia nut.40,qn tqppf it. 4

Within a vale space provided in the lower portion of said main bodytl2, a valve seat 42 is formed that closes an opening 44 below it, and, on which, a valve 46 is adapted to seat when in closed posittion as shown in said Figure l. Said shaft 36 movably extends into said'valve i and moves upwardly'and downwardly therein and-in A piston 48 sursaid hole 30, as said float 34 moves. rounds the lower part of said valve 46 andis held in position in said valve space by a screw-threaded valve plate 50 screw-threadedly connected to the threads52 at the lower part of said valve 46. Movement of said piston 48 up or down causes said valve 46 to open or close respectively. 1 v

The lower portion 12a of said main bodyis screwthreaded internally as at 56andhas a screw-threaded with said screw-threads 56 to close said valve space at the bottom.

Said valve 46 has a horizontal port 62 therein which communicates through said valve space with a horizontal discharge port 63 extending through said main body lower portion to the outside. Said valve 46 also hasan upper vertical port 64 communicating withsaid float chamber 32, and has a lower, vertical port 66 that communicates with the portion of said valve space that is below said plate 50 and valve 46 and extends to a point directly below said piston 48. Opposite said horizontal port 62 an exterior groove 70 is formed in said shaft 36 which communicates with said port 62 and, when said valve is open only, with said port 64. a

Within said valve 36 an adjusting screw 72 screwthreadedly enters at the lower central end thereof which extends upwardly to the lower end of said shaft 36, thus enabling one to correctly position the shaft 36 in open. "able position. i

As water passes from the said air chamber 10 through port 17, chamber 22, filter 25, and through said holes 28.into said float chamber 32 it runs into the conduit 64 in said valve 46 until the space below it is full. Then as the water rises in said float chamber32 the float 34 rises together with saidshaft 36, the lower portion of which rises above said conduit 66, so that the water flows from conduit 64 into said conduit 66 and into the valve space under said piston 48. This causes said piston 48 to rise, thus carrying with it said valve 46 which rises ofi said seat 42 to thereby provide an escape opening 74, shown insaid Figure 2, through which water flows out of said float chamber 32 into said opening 44 and through said valve space and said port 63 and discharges outside my mechanism. Likewise water passes through said port 64 and into said groove and said port 62 and out said port 63. r I

As the water flows out of said float chamber 32 said float 34 descends, thereby closing said valve 46. Thus no gas or air can escape.

What I claim is:

Mechanism to abstract liquid from gas comprising a main body having a float chamber therein and a valve space below said chamber and having a discharge port extending to the outside of said body in communication with said valve space, a head connected to said body and having a chamber therein, said chamber having 'means'adapted'to establish"communicationwith an outside supply of gas comprisinga port in communication with said head chamber, spacer apparatus in said head chamber supported between saidmain body and head and having an opening thereinin communication with-- said float chamber, a float within said float chamber, a

valve movably mountedin said' main bodyf and extending 'into saidj valve space and adapted to close an;opening'b e 'tween said valve space and said fioat chamber when; in closed position, a shaft attached tosaid' float and slidably extending into said spacer apparatus and into said valve,

said valve being so positionedthat liquid may be received in said valve space when said valve is open andbe discharged through saiddischarge port outside said main said valve having a screw-threaded opening in its a lower portion, and a'screw adapted to enter said opening and screw-threadedly connect with said valve and contact the lower end of said shaft whereby the position of said shaft may be adjusted.
