IMPROVEMENT IN' STEAM-CYLINDER mOILELR.

The Schedule referred to inthese' Letters Patent and making parl: of the same.

To all whom it 'may concern v Be it known that we, SIMON F. STANTON, of- Manchester, in the county of Hillsborough, and State' of New Hampshire, and OnvILLE RIPLEY, of Charles accompanying drawings, forming a part of this specication, in which- Figure 1 represents a perspective outline vie'w of this invention.

Figure 2' represents a sectiOnalVeW, showing its working parts.

Figure 3 is a plan or rear view of the piston.

Figure 4 is a -view of the front of thesa'me.

lThis invention relates to a stationarybiler, surmounting the top of locomotive-engine boilers, near the smoke-stack, having a reservoir and suitable means for conveying the. oil from 'the same to 4the steamchests for lubricating the cylinders, without the engineer or fireman leaving their cab for this purpose.

A, ig. 2, represents the reservoir, made of sheetmetal, its seams soldered, or it maybe cast of one piece of meta-l, its inlet closed'by a cap, V, and its outlet, A', an open port, communicating with :the cyliuder- B.

B is the cylinder, cast of one piece of metal, having three openings, one at the top, through which the oil passes and enters from the reservoir, the second, which is'covered by the cylinder-head W', and serves as a guide for the piston-romand the third at its further extremity, which opens" into the outlet-chamber,'aud also forms the seat for the valve H, which closes the same.

Gis the pelforatedpiston closed by the valve K, which 'piston forces the oil out of the 'cylinder into the outlet-chamber P, and thence into the conductingpipes. Y

D is the paititioned tubular piston-rod, which receives, at itsforward end, ,by a screw-tl'u'ead, the shank of the piston, and through that the valve-stem I and nut J. At the other extremity is received the hollow guide-plug Fand the rod E, encircled by a spiral spring, G;

Eis the connecting-rod operating the'piston, extending from the interior of the piston-rod to the in terior of the cab, where it terminates, and is secured by any well-known device, which is releasedby the engineer and thrust forward whenever he wishes to discharge the oil from the cylinder.

F is the'hollow guide-plug, screwed into the rear end of the tubular piston-rod, which serves to. guide the rod E, and prevents its withdrawal entirely by means of the stud on the end of the rodE, also con* fining the spiral spring G within thecavity D2.

G is a spiral spring encircling the rod E, Within the cavity D2. It compensates for any accidental movement communicated tothe rod E, by oscillation of the cab, within which the other end of the rod E is secured by any of the well-known devices.

H is. the valve closing the outlet of the cylinder B, and operated by the piston'G, nut J, and tubular rod D.

I, the valve-stem, retained within the' cavity of the piston-rod D1. by the nut J. y

J, the nut on .the valve-stem.

K, the piston-valve, which opens when the piston is withdrawn, and closes when thrust forward.

LL are thepelforations through the face of the piston C, which permit the passage of the oil through them into the forward part ofthe cylinder B, when the valve K is open.

M M areheaded screws or rivets, which keepin position the valve K.

N is the packing-box, screwed on to the cylinderhead WV.

0 is the packing around the piston-.rod D.

P is the outlet-chamber, screwed on to the forward end of the cylinder B, and which receives vthe oil as forced from the cylinder B, andjdelivers it through an open port on each side Q Q, fig. 1, into the conducting-pipes It R.- f

Q Q are the openports 'of the outlet-chamber l?.

1t -lt are the tubes or pipes which convey the oil from the outlet-chamber l domi into the steam-chests Von each side of the boiler.

S is the steam-jacket enclosing the cylinder B and its contents, and nearly covering the bottom of the reservoir A. Steam is admitted through the hollow plug T. The oiiicc of this device is to keep hot and at a uniform temperature the oil, tallow, or other lubricants contained within the reservoir A and cylinder B.

' T is the hollow plug, screwed into the top of the boiler, and is connected to the jacket by the screwcoupling U. The amount ofsteam admitted through the plug may be regulated by valves.

U is the screw-coupling connecting the plug T and steam-jacket S.

V is the screw-cap, or stopper, closing the inlet of the reservoir A, and is removed for lling the same.

W is the cylinder-head.

Various methods 'of packing the piston may be employed. lVe have found the common metallic ring to answerthe purpose better than others in use.

The prime object of this invention is economy in the use of oil or other lubricants, when applied to locomotive-engine cylinders.

Itwill be seen from the explanation of our invention that the cylinders may be lubricated simultaneously,A by either the engineer` or fireman, without leavin g their cab, by simply thrusting forward the con-` nectingrod E, whichis accessible to them within the cab at all times. y

Having thus described our invention, We claim, and' desire to secure by Letters Patent- Zl. The arrangement of the reservoir A, the cylinder B, outlet-chamber P, and conducting-pipes R R, when constructed in the manner herein described.
