OIL PUMP.
Patented June 6, 1882.
' UNIT D STATES PATENT OFFICE.
ALBERT J. WEITH, OF CHICAGO, ILLINOIS.
OIL-PIUMP.
SPECIFICATION forming part of Letters Patent No. 258,962, dated June 6, 1882.
Application filed March 11,1882. (No model.)
To all whom it may concern:
Be it known that I, ALBERT J. WEITH, of Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Oil-Pumps; and I do hereby declare that the following is a full, clear, and
through the top of the plunger-rod opening,
but will discharge such leakage through an opening below the air-chamber, to run back again into the barrel or tank, and to have other provisions, in connection with the air-chamber, which will add to the perfect working of the pump, all as more fully hereinafter described and specifically claimed.
In the accompanying drawings, Figure 1 represents a vertical section through the center line of the pump; Fig. 2, an elevation of same; Fig. 3, a section .on horizontal line 00 :10 in Fig. 1, and Fig. 4 a similar section on line 3 y in Fig. 1.
Like letters designate corresponding parts in all the figures.
A denotes a conical air-chamber, and B the pump-barrel, connected tothe bottom of the same. This pump-barrel B is secured eccentrically to the air-chambcrA in such a manner that the plunger-rod C, that is passed through the center of such air-chamber, will pass down into such barrel at or near one side of the same. This plunger-rod has a handle, a, to its upper extremity, and a hook, I), to its bottom end, which connects with the plunger 1), having valve d.
The plunger-rod O is guided in a tube, e, that projects through the air-chamber A, and is hermetically secured to the top and bottom plates of such air-chamber in such a manner that the interior opening in said tube is in no communication with the interior of the airchamber.
Just below the tube 6, underneath the airchamber A, at p, a portion of the pump-barrel B is cut out, so as to expose the pl'un-gerrod O, and below such cut or notch 10 thepump- ,rod is guided again in a short tube,f, that is soldered to the barrel. An arch-shaped plate of metal, or a segmental section, g,ot' a pipe is placed behind the tines e andf, so as to form a connection of the same, and a partition between the interior of the pump-barrel B and v the exposed portion of the pump-rod, thus forming-aniche in said barrel, through which such plunger-rod reciprocates; and the ends of the tubes cf are formed with air-tight connections at the junction of the pump-barrel B and plate g. p
I The interior of the air-chamber A com 111 unicates with the pump-barrel B through an opening at their jointing-point, and the dischargepipeE is projected through the top of the airchamber A, where it is secured by an air-tight joint, andis thence projected downward into the pump-barrel B,so as to leave an open space around it. The top end of this discharge-pipe E is curved to spout the oil downward above and to one side of the'air-chamber A.
The'seat h fora valve, t, is securedin the bottom end otlbarrel B, andbelow this is fixed a bow-shaped support, j, on which the pump and so that how jrests upon the bottom of:
such barrel, and the plunger-rod 0 being reeiprocated, with each upward stroke oil willv 'be drawn into the pump-barrel B through valve '5, while an equal amount of oil that is above the plunger D will be forced upward through the discharge-pipe E, and with each downstroke of the plunger the valve 11 will close and the oil in the pump-barrel underneath the plunger D will pass through valve d into the pump-barrel above the plunger D. The discharge-nozzle E,'extendin g higher than the top of tube 6, with pumping, a certain amount of oil would be forced through the space around the plunger-rod if such tubes 0 and f were continuous, and unless the tube "6 was provided with a stuifing-box that would close the joint around the plunger-rod herm etically. Such stuffing-box would, however, make the plunger-rod work hard, and would require frequent repacking, while without it the leakage through the top of tube 0 would cover the exterior surfaces of the air-chamber and the pump-handles with oil and grease, and would make the operation of drawing oil a nasty job, beside the waste connected therewith.
By my arrangement, as will be noticed, the escape of any such leakage will be through the top of the tube f, whence the oil will run from the niche down and back into the barrel, and the air-chamber and pump-handle will be kept clean.
The air-chamber around tube 0 being perfectly tight and only communicating with the pump-barrel, and the discharge-nozzle E extending into such pump-barrel a desired distance, the oil can never rise into such airchamber unless the pump was being turned upside down while its barrel is filled with oil. The advantage of this arrangement is that the elasticity of the air in the chamber A is utilized to better advantage.
The check-valve nwill be closed by the pressure ofthe oil that is above and in nozzle E, and will preventsuch oil from escaping through the top of tubef while the pump is at rest or while it is removed from the oil-barrel. This valve 91., however, is not essential, and can be dispensed with by arranging the top of tube fwith a stuffing-box for hermetically closing the joint around the plunger-rod 0.
As will be noticed, this pump is simple in construction, and will insure a clean pumping ing the plunger-rod, and which furnishes an outlet for any oil forced into or through such tube, all substantially in the manner set forth.
'2. In oil-pumps, the air-chamber A, having central tube, 0, for guiding the plunger-rod C, and discharge -nozzle E, in combination with the pump-barrelB, eccentricallyconnected with such air-chamber A, substantially as and for the purpose set forth.
3. In oil-pumps, the air-chamber A, having central tube, a, for guiding the plunger-rod G, such tube e extending through both ends of the air-chamber, and being connected therein by air-tightjoints, substantially as and for the purpose set forth.
4c. In oil-pumps, the air-chamber A, having central tube, 6, for guiding the plunger-rod O, and the pum p-barrel B, eceen tricall y connected with such air-chamber A, in combination with the discharge-nozzle E, extending through the air-chamber into such pump-barrel B, all substantiallyas and for the purpose described and shown.
5. In oil-pumps, the air-chamber A, having tube 6, and the pump-barrel B, having notch 12, tubef, and partition g, in combination with the pump-rod passing through and guided in tubes 6 andf, all substantially as and for the purpose set forth.
6. In oil-pumps, the air-chamber A, having central tube, 0, and the pump -barrel B, con nected eccentrically with such air-chamber A, and having notch 1), tube f, and partition g, in combination with the plunger-rod 0, passed through the tubes .9 and f, and with the discharge nozzle E, projected through the airchamber A and into the pump barrel B, all substantially as and for the purpose set forth.
7. In oil-pumps, the air-chamber A, having central tube, 0, and the pump barrel B, connected eccentrically with such air-chamber A, and having notch 12, tube f, partition 9, and check-valve n, in combination with plungerrod 0, passed through the tubes e and f, and with thedischarge-nozzle E,pro jected through the air-chamber A and into the pump-barrel B, all substantially as and for the purpose set forth.
In testimony that I claim the foregoing as my invention I aflix my signature in presence of two witnesses.
ALBERT. J. VVEITH.
