cHIcAeo, ILLINOIS, A f coR-l AUxILlARY olL-CUP Fon SIGHT-FEED' LUBBIGAToIis. i

B'efit known that I, FRANK W.' EDWARDS, a c'itizenof the United States, residing at Logansport, in the'county of Cass and State of Indiana, have invented ya certain new and useful Improvement in Auxiliary rOil-Cups for Sight-Feed Lubricators, of which. the fol.-

lowing is a full. clear, andexact description.

In the use of 'condensation-displacement sight-feed lubricators it is sometimes necese sary to replace or supplement thefeed of oil 'from the oil-bowl to one or more ofthe sightfeeds by anauxiliary oil-cup, and it is a com-l mon practice to construct such lubricators with facilities for introducing these auxiliary oil-cups.

i The present invention is concerned with this sort of apparatus, andthe object of the invention is to provide an auxiliary device that may be applied to the upper feed-arm of the lubricator, so that the auxiliary supply of oil can bedelivered to the upper feed-arm and into the oil-pipe without shutting off the lubricator steam or engine throttle.

' the lubricator of Fig. 1.

In the accompanying drawings, illustrate ing the invention, in the several 4figures of which like parts are similarly designated,

'Figure 1 is an elevation of a locomotive-lubricator of theclass described having two auxiliary oil-cups applied to its cylinderfeeds..v Fig. 2 is a cross-section, partly in end elevation and on a larger scale, of a portion 4of Fig. 3 is a crosssection of a modification. f

The oil-bowl 1, condenser 2, circulatingpipes 3, water-'valve 4, pipe-plug 5, .pressurevalve 6, steam-chest or cylinder sight-feeds 7, air-pump sight-feed 8, observation glass or index 9, oil-bowl drain-valve 10, filler-plug 1.1, and other parts shown, but not particularly described, may be of usual or approvedv construction and' are here shown as of the construction known on the market as the Chicago locomotive-lubricator, Class C, but it is to be understood that the present invention is not'limited to its use with that form of lubricatoralone.

As shown, the auxiliary oil-cups 12 are provided with nipples 13, screwed into the nipples of theupper feed,-arms 14 of the Since these oil-cups are alike, a description ofone will suiiice for both. The oil-cup, preferably,

fis cylindrical, with Aa saucer-shaped' top'15,

having afilling-hole 16 made as a valvesseat. The filling-plug' 17 is' adapted to be seated in the filling-hole and has a screw-threadedex tension 18 screwing into a hollow boss, 19, rising-from thebottoi'n 20. This extension has a lateral hole 21 above the'boss'and intersecting a longitudinal hole 22, opening at the bottom of the extension and within the boss. The' boss is pierced transversely at the bottom and in line with the nipple 13 andthe opposite nipple 23. lThis nipple'23 supports the oile'cup feed-valve 24, which has screwthreaded engagement therewith and extends through the opening in the boss, and its point is coned to serve as a valve in a seat 25 in the nipple 13. The oilecup has a drain-valve 26 in its bottom, which drain-valve is made as a screw-plug having a longitudinal bore 27, intersected by a lateral bore 28. The upper feed arm 14 has the pressure controlling valve 29 seating in the top of the sight-feed, and the same I'itting has a tallow-pipe connection 30.

Instead of the filler-plug 17, screwed into the boss, rising from the bottom of the oilcup I may use an oil-cup 31, Fig. 3, having a screw-threaded hole 32, in which is screwed One side of the oil-cup is made with a channel 34, opening at its top at 35 into the oil-cup and having an opening in its bottom for the reception of the plug or valve 24. Both forms of oil-cups operate in substantially the same Way-that is to say, the oil lcontained therein is displaced by steam-pressure-in one case through the channel formed by the bore 21 22 and in the other case-by the channel 34 35. The -water of condensation overflows .through connection 30. I

i In order to fill the cup, it is first drained thoroughly by opening the drain-plug 26. Before the drain-plug is opened, however, the valves 24 and 29 are closed, and the fillerplug yis opened suiciently to vent the cup. After the cup is drained the valves are closed and the iillereplug is opened wide, and then the oil is poured into the cup through the filler-plug, and after the oil-cup is filled then the ller-plug is screwed down tight to its seat and feed-valve 29 is opened wide, per- Initting the pressure from the upper feedarm to pass into the bottom of the oil-cup and effect the movement or feeding of the oil. Each of the channels shoWn by parts 21 22 or 34 35 constitutes asort of circulating-passage, Which prevents the oil from stagnating in the to of the cup.

hat I claim is- 1. In a sight-feed lubricator, an oil-bowl, a sight-feed adapted to loe supplied with oil from the oil-bowl and having an upper feedarm provided With a pressure-controllingvalve, in combination With an auxiliary oilcup applied in the upper feed-arm and in communication With the pressure-controlling valve, and having itself an independent pressure-controlling valve7 and an oil-circulating channel.

2. An auxiliary oil-cup having means for directly applying it in the upper feed-arm of a sight-feed lubricator, and also having a top filling-plug, a pressure-controlling valve arranged in its bottom, and an oil-circulating channel controlled by said valve.

3. An auxiliary oil-cup for sight-feed lubricators, having a filling-plug in its top, a

boss into which said filling-plug screws, an oil-circulating channel in said plug, means to connect the oil-cup With the upper feed-arm of a sight-feed, and an independent pressurecontrolling valve arranged in the oil-cup and controlling the admission of pressure into the oil-cup and the discharge of the oil therefrom.

4. An auxiliary oil-cup for sight-feed lubricators, having a iilling-plug 1n its top, a boss into which said iilling-plug screws, an oil-circulating channel in said plug, means to Vconnect the oil-cup with the upper feed-arm of a sight-feed, an independent pressure-controlling valve `arranged in the oil-cup and controlling the admission of pressure into the oil-cup and discharge of the oil therefrom, and an oil-cup drain-plug.

In testimony whereof I have hereunto set my hand this 16th day of June, A. D. 1906,
