PUMP.

Specification of Letters Patent.

Patented May 30, 1916.

Application led March 29, 1912. Serial No. 687,291.

To all whom t may concern Be it known that I, .FRANK R. CHILDREN,

a citizen of the United States, residing in,

Council Bluffs, in the county of Pottawattamie and State of Iowa, have invented a new and useful Improvement in Pumps, of which the following is a specification.

This invention relates to improvements in pumps.

The object of the invention isto provide a pump, such, for instance, as is used in transferring oils from a barrel, and which is adapted to be attached directly to the original barrel.

Another object of the invention is to so arrange and construct the delivery spout of the pump as to prevent loss of 011 or other material due to dripping.

Another object of the invention is to prolvide a structure comprised of few parts, simple and compact in arrangement, and one which may be cheaply manufactured.

My invention furthermore consists in the novel construction of parts and devices and in the novel combinations of parts and devices herein shown and described and more particularly specified in the claim.

In the drawing forming a part of this specification, Figure 1 is a vertical, sectional View, showing my improved pump attached to a barrel, the latter being shown as broken in order to get the same on the sheet. Fig. 2 is a partial, detail, vertical section, taken on the line 2 2 of Fig. 1. Fig. 3 is a horizontal sectional view, taken on the line 3-3 of Fig. 1, and Fig. 4 is a transverse, horizontal section, taken on the line 4 4 of Fig. 1.

In the drawing, I have shown the pump as comprising a cylinder or casing within which slides the piston 11, the latter comprising preferably a pair of leather washers 12 secured in place by washers 13 screwed on the lower end of a rack member 14. The rack member 14 is adapted to be reciprocated up and down by means of a pinion 15 mounted on a shaft 16 supported in brackets 17 at the upper end of the casing or cylinder 10, the shaft 16 being provided with a crank arm 18, whereby the latter may be manually operated. Screwed into the bottom of the piston or cylinder 10 and communicating with the interior of the latter is a T-pipe 19 having screwed thereinto on one side the elbow 20 and at the bottom thereof the inlet pipe 21. Secured in the upper end of the inlet pipe 21 is a valve seat 22, preferably of soft metal and coperating with a ball valve 23, the latter being limited in its upward movement by a pin 24 secured in the T- member 19. The inlet pipe 21 is provided with a sflidable sleeve 25 adapted to be ad- Justably' retained in position on the pipe by means of .ifi set screw 26. The sleeve 25 is exteriorly threaded and is adapted to fit an interiorly threaded bushing 46, such as is ordlnarily provided on original barrels containing oil. I have shown the sleeve 25 as threaded into v:such a bushing in the top 27 of a barrel or inclosed receptacle 28 adapted for shipping oils or other liquids. Threaded into the upturned end of the elbow`20 is a short nipple 29, the same being provided with a valve seat, preferably ofsoft metal 30 and in which is adapted to be seated a ball valve 31, the latter being limited in its upward movement by a pin 32 secured in the lower end of a vertically extending spout 33, the latterbeing attached to the nipple 29 by means of a coupling 34. The spout 33 is provided with a short, downturned end 35, and at the joint or bend in the spout formed between the main portion of the'spout and the downturned end 35 onthe interior thereof is an upwardly extending ledge or projection 36.

With this structure it will be apparent that waste of oil or other liquid due to dripping will be prevented by this ledge 36, since the oil or liquid remaining in the tube, after the downward movement of the piston l1 has ceased, will fall back down the main portion of the spout 33. By making my improved pump in such a way that the same may be readily secured'to original barrels containing oils or other liquids, I also prevent the waste of oil or liquid due to transferring the oil from the original containers to a storage tank in the manner which has heretofore been customary. Another advantage of my construction resides in the fact that the pump is readily interchangeable from one ori inal barrel to another.

The pump is a justable with respect to The pump is accurately adjustable to bring the spout over a desired delivery station rangement permits the changing of the position of the spout in a horizontal plane without affecting the pipe adjustment.

By using the original receptacle for stor-v age purposes, the contents are kept cleaner than by the old method where the oil or other liquid is transferred from the shipping eceptacle to a storage tank, and furthermore danger of loss from leaky faucets or valves and the consequent danger from fire where inflammable liquids are used is' avoidedby my method of using the original container in connection with the pump. With my improved form of pump, it will be obvious, also that if there is any of the oil or other liquid spilled in the transferring of the liquid from the receptacle to the measuringy can, the same may be easily cleaned up and there will be no danger of y A pump having the drippings or spilled contents soaking into the Hoor.

I have shown one form of my inventio but it will be understood that the same i merely illustrative and that many change and vvariations may be made -without de parting from the spirit of the invention, and all such changes and variations are contemplated as fall within the scope of the appended claim.

I claim an upwardly extending outlet spout or pipe provided with a down` turned vertically extending nozzle at the end thereof and being provided further with an upwardly e'xtendlng sharp ledge projecting from the intersectlon of said pipe with said spout, Said ledge forming a restricted passageway at the intersection of the main portion of said pipe and the down-turned nozzle, theouter face of said ledge being disposed substantially .in the plane of the adjacent face of said nozzle whereby to provide means for suddenly stopping the flow of liquid through the spout without subsequent drip or waste.
