MEASURlNG-PUIVIP.
SPECIFICATION forming part of Letters Patent No. 720,638, dated February 17, 1903.
Application filed May 13, 1902.
To all whom it may concern..- Y
Be it known that we, JOHN J. TOKHEIM, residing at Thor, in the county of Humboldt, and EDWARD O. MANSFIELD, residing at Cedar Rapids, in the county of Linn, State of Iowa, citizens of the United States, have invented certain new and useful Improvements in Measuring-Pumps, of which the following is a specification. t
This invention relates to pumps adapted for the drawing and measuring of liquids, such as oil, the construction being such that a delinite quantity may be pumped into a graduated transparent receptacle,where the amount may be easily seen by a purchaser, and thence quickly emptied into a vessel for delivery to such purchaser, i
The invention embraces `certain improvements in the construction of a measuring* pump describedin Letters PatentNo. 640,336, issued to John J. Tokheim on the 2d day of January, 1900, the nature of which improvements will appear in l,the description and claimsfollowing, reference being had to the accompanying drawings, in which- Figure l is a side view of a pump embodying our invention, butwithout the drip-pau. Fig. 2 is a central vertical section of the same as seen from the front. section, showing detail of the measuring-resa" ervoir and its connections, the overflow an/d the vent pipes.
In the main the pump is similar in construction to thatfshown and described in the patentabove referred to.
leverB therefor', and a fulcrum-rod C,pivoted to a base D. The pump-rod passes down a pipe E, screwed into the bottom of the base,
.to a cylinder, (not shown) and thence by a It comprises a pump-` piston, the rod'A of'which is shown, a hand-- Fig. 3 is an enlarged,l
Serial No. 107,207. (No model.)
Y certained volume of liquid. In practice this reservoir is made of glass and graduated to denote fractional parts, as of a gallon. In the middle of the reservoir is a stand-pipe J, extending from near the dome of the reservoir to the .base D, where it communicates by a chamber D2 with a drain-pipe K, leading back to the storage-tank- A suitable basin or pan L takes the drip from the bib. This is provided with a strainer L' and a little below it an inclined drip-collector L2, emptying into a discharge-pipe M.
The improvements which form the subjectmatter of this invention will now be more particularly described.
In the patent above referred to it will be seen that the overiiow-pipe was provided below the base (which is usually secured to the door) with an elbow and united by a lateral branch with a vertical pipe depending from l the center of the drip-pan. In practice this was found to be objectionable, as in many cases the joists and other timbers below the door interfered with the pipe connections, making it difficult to mount and connect up the pump. In our improved base the overilow pipe screws into the top of the base and discharges its contents into a chamber D2 formed therey in. Another pipe screws into the bottom of the base and opens into the same chamber, and this serves as a drain-pipe to carry the overflow back to the storage-tank. The same chamber connects with the drip-pan above the floor by a short pipe M, as clearly shown in Fig. 2. It will be observed that the bottom of the chamber D2 is inclined at D3 to facilitate the outflow of the discharge from the overflow-pipe.
Instead of the pipe-fittings and sections of pipe to which the measuring-reservoir was attached, as shown in said former patent, a single casting is now used. At one end is an el` boss G3, into which the nipple of the base I screws. The upper end of the overflow-pipe proper has a running thread for a considerable distance, so that the pipe may be run into the head far enough to allow the lower end of the pipe to clear the base as the head is screwed on the pipe F. When thus screwed on, the overflow-pipe is run down, screwing into the base at the lower end, and is secured ln proper position with a tight joint at the head bya lock-nut N. The upper end of the pipe extends a short distance into the head, as best shownin Fig. 3, and to it is connected bya coupling J2 a short section of pipe J', reaching nearly to the dome of the reservoir. This pipe is considerably smaller than the nipple of the reservoir-base, thus leaving an annular opening for liquid from the pump to the reservoir. When the liquid rises above the upper end of the pipe J', it of course flows down the pipe and passes back to the storagetank, as above mentioned.
To facilitate the escape ot' the overflow, a vent-pipe O is mounted inside the overflowpipe and terminates near the lower end of the same in a curved outlet O. A separate section O2, provided with a thimble O3, is adapted to slip alimited distance on the upper end of the pipe O and is held normally pressed upwardly by a spring P between the thimble and a collar O4. This admits of the upper end of the vent-pipe reaching the dome of the reservoir and at the same time allows for variations in the heights of such reservoirs. Air is admitted to the vent-pi pe through a notch O5.
It is to be understood that while the overflow-pipe J would of itself carry away the liquid rising above its upper end it would do so with considerable gurgling and more slowly than is desirable. The auxiliary vent allows such overflow to run down the pipe J very quickly.
Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is
l. In a pump of the kind designated, a base having a central hole in the bottom to take the delivery-pipe and pump-rod, a chamber communicating therewith, and having a hole opening upwardly to take a vertical continuation ot the delivery-pipe, and a chamber opposite thereto, with holes opening upwardly, downwardly, and laterally, to take the overflow, drain and drip pipes, respectively, substantially as described.
2. In a measuring-pump having supply and overflow pipes substantially as described, a vent-pipe inside said overiiow-pipe, extendinga little distance above it and terminating in a curved outlet at the lower end near the end of the overflow-pipe.
3. In a measuring-pump having a reservoir and overilow-pipe, substantially as described, a vent-pipe comprising two telescoping sections, the lower one secured inside the overflow-pipe, and having a collar or shoulder near its upper end, a spring above said collar, and a short section or" vent-pipe telescoping the upper end of the fixed vent-pipe, with its vented upper end touching the dome of the reservoir.
In testimony whereof We affix our signatures in presence of two witnesses.
JOHN J. TOKHEIM. EDWARD O. MANSFIELD.
