LEVI S, LAPHAM, OL1 PROVIDENCE, RHODE ISLAND, ASSIGNOR TO MARY S. BROWN, OF SAME PLAGE- Lettersv Patent o. 104,168, dated June 14, 1870.
IMPRQVEMENT IN oIL-PMPS.
i The Schedule referred to in these Letters Patent and making part Of the Same.
I, LEVI S. LAPHAM, of Providence, in the county .of Providence and State of Rhode Island, havevinvented certain Improvements in OilPnmps for Lubricating Steam-Engines and Mach-inery, of which the following is a specification.v
Nature and Objects of the Invention.
My invention relates to the arrangement of the valves in the pump, ius'uch a manner that the pump may be readily filled with oil -from the reservoir without, and then injected into the steam-chest or cylinder of an engine, without the necessity of opening or shutting any.cock.or valve, as 'has heretofore been necessary iu all other pumps, to prevent the escape of steam or the blowing out of the heated oil.
Description of thcAccompan-ytny Drawing.
Figure 1 is av side elevation of the pump, 'with ythe lower portion Vin section, showing the working parts.
Figure 2 is a plan of' the base, showing the location .of the valves.
i i are two valves, which prevent the return of the oil to the reservoir without.
p isthe passage from the pump to the outlet.
r is a valve, which prevents the oil from returning to the pump after having once passed it.
"w isla spring, which serves to keep the valve r `closed .when no pressure is on the pump.
vs is a plug, which serves as a seat for the spring, through which is an opening, t, for the passage oi the oil. u is a plug, which may he removed and the oil taken from the side instead of the bottom.
The oil, in passing from the reservoir to the engine, is drawn by the piston a through the passages e e, lifting the valves 'i t', passing through the passages o o, in tig. 2, into the space f, left bythe piston a.v By a reversed motion of the piston, the oil in the space fis forced down the passage p, opening' the valve r, and thence out at the opening t or u, as the case may be.
Claim..
I claim as my invention- The combination of one or more valves, asi i., and the valve r, together with the passage o, arranged substantially as and for the purpose herein set forth.
LEVIS. LAPHAM.
