OIL AND LIQUID PUMP.

SPECIFICATION forming part of Letters Patent No. 239,828, dated April 5, 1881,

Application filed July 7, 1879.

To an whom it may concern Be it known that FRANCIS NICHOLS, deceased, late of the city and county of New London, State of Connecticut, and WOLCOTT B. MANWAEING, and OLIN L. LrvEsEY, both of the said city and county of New London, did invent certain new and useful Improvements in Pumps for Pumping Oil and other Liquids, which invention is fully described in the fol- 1o lowing specification and shown in the accompanying drawings, making a part thereof.

These improvements relate to that class of pumps in which the pump action is produced by the compression and rarefaction of air in a I 5 chamber between the valves, the air being compressed by a hollow collapsible bulb and rarefied by expansion of such bulb. The apparatus can also be converted into a siphon, and may be used as a convenient means for drawing oil or liquid from any vessel.

' Figure 1 is a view of the pump complete. Fig. 2 is a vertical section of Fig. 1 through the center thereof. Figs. 3 and show variations in the form of the top of the outer 2 5 vessel or cylinder of the pump.

A represents a metallic vessel, generally cylindrical, and whichfor ordinary uses need not be more than three, or four inches in diameter and four or live inches high. It can,

however, bemade of any size desired. In the lower end of this vessel is formed a valve: seat, a, upon which drops or rests a puppetvalve, 00, such valve opening upward,and being prevented from rising too highbyaystem,

I 3 5 of, which extends down through the seat and has an enlarged head, a upon it. To the bottom of such vessel, below the valve a, connects the suction-pipe B, which enters the vessel containing the oil or liquid to be drawn.

4 To the top of this vessel A is attached an elastic collapsible bulb, C, the neck of which enters the nipple 0, thereby permitting an easy removal of the bulb whenever desired. Within this vessel A is a smaller vessel, D, which has in the lower part thereof a valve-seat, d, and puppet-valve 01, opening upward in the same manner as does the valve 0/, and which is prevented from rising too high by the headed stein 01 This inner vessel, D, is fixed within the upper partof the inclosing-vessel A, but so that there will be air or liquid space above and around it, and extends downward within the vessel A some distance, generally about one-half or two-thirds the depth of such inclosing-vesse'l. Connecting with this inner vessel D near its upper part, and opening from one side thereoflpassing by a ti ght collar or thimble, E, through the vessel A, is fan eduction or discharge tube, E, which may be made of such a length as to convert the'ap- 6o paratus into a siphon, and in the lower end of which is a-faucet or stop-cock, F. L

The operation is as follows When the bulb C is compressed by the hand a portion of the air in the chamber A is forced through the valve d into the chamber D and outthrough the eduction-pipe E, the faucet F being left open. As the bulb is allowed to expand the air in A is expanded or rarefied and the oil or fluid rises in the tube'B and enters the chamber A. As the bulb is further compressed and allowed to expand the oil or liquid willrise in both chambers A and D and be discharged from thetube E and it this tube is lengthened so as to form the long leg of asiphon, the oil or liquid, after it has commenced to flow, will continue to do so unless stopped by the stopcock F or by the removal of the bulb C. The pump, by the combination, with the tube E, of the stop-cock F, is thus converted into a convenient apparatus for drawing in small quantities oil or fluid from a barrel or other vessel. The bulb C is placed, as will be seen from the drawings, about centrally in the top of the vessel A. This position is found from experiment and trial the most desirable, as securing the most effectual and uniform operation of the apparatus, the air being thus distributedmost equally upon the surface of the fluid in the vessel A, and all swashing or back flow of the liquid when the bulb expands being substantially prevented. If the bulb C is placed on the vessel A near one side, as at 0, when the bulb is compressed the air strikes with greatest force upon only part of the fluid, or at one side of the vessel,and then when the bulb expands the liquid surges or flows back,

and frequently to such an extent as to enter the bulb. This, particularly if the fluidis oil, soon so injures or destroys the bulb that it is frequently necessary to replace it. When, however, the chambers A and D and bulb G are of sufficient relative dimensions, and the two chambers are properly arranged with reference to each other, and the bulb is so placed that the air will be delivered so as to act equally, or substantially so, upon all parts of the surface of the oil or liquid, such surging or flow is prevented, and the fluid will not enter the bulb to injure or destroy it. The most satisfactory working of the pump is effected when the capacity of the bulb O is such that it is not greater nor much less than the airspace in the chamber A.

To secure a more uniform delivery of the air upon the surface of the fluid, the top of the,

inner vessel, D, is best made arch ed orronnded, as shown in Fig. 2; but if the top otsuch vessel is made flat, or nearly so, the same efiect, substantially, will be secured by means of a perforated plate, such as is shown in Fig. 3, placed just below the top of the vessel A, or by radiating tubes, as shown in Fig. 4, placed on the inner surface of the top of the vessel A.

The upper side of the thimble or collar E is preferably made curved or arched for securing a more equable action of the air upon the fluid in the vessel A.

To keep the suction-pipe B from entering the cask or vessel from which the oil orliquid is to be drawn so far as to reach or disturb any sediment, and to facilitate the em j tying the cask or vessel only to a given depth, the suction-pipe is fitted with a tapering collar or bung-bush, B, which is placed in the bunghole or other opening in the cash. This collar is, for convenience, in two parts or halves, so that it will hug tightly the pipe B, and being tapering will fit holes of difl'erent diameters, and will also tend to steady the pump while it is being operated.

We are aware of English Patent No. 2,123 of 1861, the same being an apparatus for administering injections. It differs from our pump in construction, operation, and use, and we lay no claim to what is therein shown and described.

What is claimed as new is- 1. An oil or liquid pump composed of an initial receivin g-ch amber, A, provided with an induction-pipe and a valve and a collapsible bulb, O, and a final discharge-chamber, D, arranged within the former, so that there shall be space above and around it, and provided with a valve and eduction-pipe, the chamber and bulb being arranged and of such relative dimensions, substantially as set forth, that the liquid will first enter chamber A and then chamberD without passing into bulb C, as and for the purpose set forth.

2. In an oil or liquid pump, the combination of chamber A and collapsible bulb 0, located substantially as described, with chamber D, having an arched or curved top, the whole constructed and arranged as set forth, whereby the liquid is prevented from swashing and entering bulb O and the air is distributed on all sides of chamber A, substantially as set forth.

3. In an oil or liquid pump, the chamber D, constructed with an arched or curved top for the purpose of distributing air on all sides of such chamber and facilitating the flow of any liquid from oft'it.

4. In an oil or liquid pump composed of the two chambers A and D, the combination ofa collapsible bulb, O, and a perforated plate located between the tops of the two chambers, as and for the purpose set forth.

5. In an oil orliquid pump, the combination of chamber A, chamber D inclosed therein, collapsible bulb C, and a device located between the tops of the two chambers, adapted to uniformly distribute air over the surface of the liquid, substantially as described.

6. In an oil orliquid pump, the combination ot'chambers A and D, thelatter being located within the former, and both provided with puppetvalves, the collapsible bulb (J, and eduction-pipe E, provided with stop-cock F,

the several )arts bein arran ed as shown a, a 7 9.,

tb operate as described.
