SPECEFICATION forming part. of Letters Patent No. 315,551, dated April 14, 18.85. V Application tiled November l0, 1884. (No modul.) u

r of Michigan, have invented a new and useful Improvement in Lubricators, of which the fol lowing is a specification.

My invention relates to that class of lubricators in which the oil is supplied in limited quantities as it is displaced by water, the product of condensation being admitted to the oilchamberin carefully-regulated quantities.

It has for its object the production of a compact and cheap apparatus which may be attached directly to the top of a horizontal steam-pipe,or to the top of the steam-chest or other part to be lubricated; and it consists in the use of an internal water and steam chaml,

ber and an exterior oil-chamber cast in one piece and connected by such pipes, and com-.

this specification, Figurelis a vertical sec-` tion. Fig. 2 is an elevation, partly in section. Fig. 3 is a horizontal section on the line x of Fig. 1.

The same letters are employed in all the iigures inthe indication of the identical parts.

The external cylinder, A, and the internal cylinder, B, are concentric and cast inone piece, being united bythe neckG, -extended to the outside in the stud-c. Opposite to the latter, and projecting in like manner beyond the cylindrical shell A, is the stud c', these studs being bored out and threaded internally to receive the threaded stems -of the valves E and F, and externallytoreceive the correspondingly-threaded stuiiing-boxes e and f. The cylindrical shell A is closed at the top by the screw-plug G, and at the bottom by the vertical tubular plug D, which contains two parallel ducts, 1 and 3, and is inserted into the opening a2 in the bottom of the cylinder A, and tapped into'threaded annular flange b2 on the lower end of internal cylindrical shell,

' B. rIhe jam-nut L, set firmly against the end of cylinder A, holds the plug D in place and packs the joint between the plug and the cyl- I inder. The lowerend of the plug D has cut upon its yperiphery a thread of coarser pitch than that of the plug at Z, and by this the lubricator may be attached to a horizontal steampipe, or to the top ofthe steam-chester other part to be lubricated.` The cylindrical shell B is closed at the top b by the screw plug or cap forms the standard or support for the entire apparatus.

dieular hole to receive the connecting-pipe O, which leads from tube 2 inside the valve-seat to the. duct 3, and thence to the dischargeoritice o. The pipe O is closed at its upper lend, andhas its lower end tapped into the -upper end of plug D at the upper end of the duct 3. Another vertical pipe, S, opensnear the top of the chamber, andis tapped into the end of the plug D at the upper end of the duct 1, terminating belowin the orice s.

hole, P, through the projection d, formed by cut off or opened more or less by the adjustment of thevalve F. The pipe m communiof the indicator-glass K, which is a glass tube held between glass holders N and N and made tight bythe packing-rings m, n. The lower glass holder, N', communicates with the 4interior of -Tthe chamber A by the tube J, and with the open air when the tents of chamber A to flow out through a duct nected with the outside by holes opening into thestem and immediately below the seat.

The apparatus thus constructed is operated as follows: The plug or standard D being tapped into the steam-pipe or steam-chest, the plus the external chamber, A, when the plug is replaced. When steam is admitted to the pipe and pipes 1 and S and ll gradually the interior H, and at the bottom by the plug D, which p. 6c vIt has at' the top a stud, d, bored,v with a horizontal tube, 2, the end of which r .y forms a seat for the valve E, and a perpen` thickening the shell at that point in casting. j This duct Bleads Vfromnear the bottom of the chamber to the branch pipem,(being closed at r the top,) with which its communication maybe p cates by means of the pipe T with the interior4 formed in thel middle of valve-stem and con` Another tube is formed within the shell B by boring "a I drain-valve U` is with- `drawn from ,its seat, so as to allow thel cona recessed chamber around the upper end of G being removed, oil is poured in to lill or chest, it will rush in through the orice s,

. the pipe 2,

chamber, B, with water, the product of condensation. If, now, the valve F is slightly opened, this Water will ilow up the duct P, past the valve, and through the pipes m and T, into the interior of the indicator-glass K. As this glass has an opencommunication through J with the interior of the chamber A, the oil will stand in the indicator-glass at the same level as in the chamber, and the Water, coming through m T and falling onto the oil, will sink through the same in visible quantities, and the valve E having been opened will displace an equal quantity of oil, which, escaping through Will ilow down the tubes O and 3 V'and be'discharged through the orifice o. By

this means oil may be supplied to the part to be lubricated in quantities regulated at the will of the operator, and as it descends through the oil the ,Water will be risible and indicate to the eye the rate at which the oil is being fed. As the apparatus is placed immediately over the place where its work is to be performed, all its operations are performed by the direct force of gravity and with a minimum of loss. The steam and water chamber B being placed in the interior ofthe oilchamber and in constant connection with the steam-boiler when the apparatus is at work, it follows that the oil will be maintained in a state of uidity.

While I have presented the apparatus in the best form known to me, it is manifest that it may be modified in form and yet retain the essential principle of operation. Thus it is not essential that the steam and water cylinder should be entirelyincl osed by the oil-cylin der, as the oil can be maintained in a liquid condition under ordinary exposure Without such entire inclosure. So the feed will be continued in the same way, although the tube K maybe opaque and the position of the valve and pipes may be changed; nor is it essential that the two cylinders' should be cast in one piece, though that is the cheaper way to make them, and other changes may be made, still retaining the practically-essential features of my invention by `which it is distinguished from others before known-viz., an oil-chamber inclosing a steam and Water chamber to such'anY extent as to maintain the fluidity ofthe oil under ordinary conditions of exposure, the ducts and valves controlling the outflow of water and of the oil as it is displaced by the Water.

Iam aware that a steam-induction pipe leading to a water and steam chamber placed What I claim as my invention, and .desire to secure by Letters Patent, is-

l. A lubricator having an oil-chamber surrounding and inclosing an interior steam and Water chamber, in combination with a transparent tube filled normally with oil, through which the water falls in visible quantities in its course from the water-chamber to the bottom of the oil-chamber, substantially as set forth.

2. In combination with au exterior oil-chamber, au interior water aud steam chamber, a valve, F, and tube for admitting water from the latter to the former in regulated quantities, and a tube for discharging oil from the upper part of the oil-chamber as it is displaced by water introduced into said chamber, substantially as set forth.

3. The exterior oil-chamber and interior water and steam chamber cast in one piece and connected by the neck C, substantially as set forth.

4. The combination of an exterior oil-chamber, A, an interior Water and steam chamber, B, and the plug D, connecting the two, and also forming a standard to support them both at the same time that it forms an extension of the interior pipes, S and O, substantially as set forth.

5. The combination of the exterior and interior chambers A and B, the plug D, counecting the two, the steam and oil pipes 1 S and 3 O, the Water-pipe P, and valves E and It-O F, arranged in relation thereto, substantially as set forth.

As Witness my hand executed in the pres ence of two subscribing Witnesses.
