SPECIFICATION forming part of Letters Patent No. 414,278, dated November 5, 1889.

Application filed January 14, 1889. Serial No. 296,237. (No model.)

To all whom it may concern- Beit known that l, EDWIN D. BANGS, of Milwaukee, in the county of Milwaukee, and in the State of lNisconsin, have invented certain new and useful Improvements in Oil-Oups for Lubricating Locomotive and Other Engines; and I do hereby declare that the following is a full, clear, and exact description thereof.

My invention relates to oil-cups for lubri cat-ing locomotive and other engines; and it consists in certain peculiarities of construction, as will be fully set forth hereinafter, and pointed out in the claims.

In,V the drawings, Figure l is a vertical central section through the preferred form of my device on the line l l of Fig. 2. Fig. 2is a plan view of the same, with the cap removed and parts broken away.

A represents the cylinder of the cup, the upper part of which is externally screwthreaded, as shown at c, for the reception of the correspondingly-screw-threaded depending circular ange b of the cap B, which latter has an upward-extendin g central neck C, having interior screw-threads for t-he reception of a correspondingly-screw-threaded plug D, having a central vertical perforation d for the admission of airinto the cup above the oil, and below this neck the cap B is formed into a central feed-hopper I, having a feed-opening t', to one side of which is a vent c, preferably diagonal, communicating with the interior of the cylinder A.

E represents a vert-ical column integral with the inside of the cylinder, provided with a vertical channel e, which also extends through the nipple E', which is externally screw-threaded for attachment to the rods or pitmen or other moving part of the engine. The bottom A of the cylinder is tight, and from the same, on the inner side, directly opposite the described column, there rises the curved guide F, for a purpose hereinafter described.

G is an arc-shaped sliding plate on top of the column E, (andadjustably secured thereto by means of slot g in said plate and setscrew j passing through said slot into the top of said column,) while the other end of said plate G is formed with an opening H, guarded I ad j ustm en t.

by inwardly-tapering walls h to form a funnel, the opening H being more or less in register with the top of the vertical channel e, according to the adjustment of the said plate G, whose edge adjacent to the inside of thc cylinder A conforms in curve thereto.

My oil-cups may be provided, if desired, with windows K K, secured to the cylindrA by suitable frames k k and rivets, as shown.

The Operation of my device is as follows: To determine the requisite flow of the oil through the channel e, (which naturally varies according to the quality of the oil and the temperature of the air,) the cap B is removed and the cylinder of the oil-cup is filled even full with oil, and the plate G adjusted to cover more or less of the channel e, and when the opening H in said plate is in such position with reference to the channel e that the requisite number of drops per minute of the oil will pass through said channele, then the set-screw j is tightened to place, and the plate G thus secured in this preferred The oil is allowed to drain off till the space above said plate G is free, and then the cap B is screwed to place, and the oil-cup is attached by its nipple E to the part of the engine to be lubricated thereby. rPhe cap B isnot removed to lill the cup, except in the first instance of testing the flow and adjusting the plate G, as just described; but the plug D is removed and the cup replenished through the neck C, and when oil shows above the opening z' of the feed-hopper I the cup is sufficiently filled, and then the plug D is screwed down to place, the space inside the neck O below the bottom of the plug D and in the hopper I forming, with the space in the cylinder above the oil, an air-cushion, which materially aids the flow of the oil through the channel e.

It will be understood that the part of the engine to which my oil-cup is attached has a reciprocating motion, and with each forward or upward motion of said part the oil inside the cup, directed by the curved guide F, is injected up over andkinto the opening between the walls h of the plate G, and thence finds its way through the opening H into the channel e, and thence to the journal, slides, or other part to be lubricated, and this action will continue just so long as there is a single drop of oil in the cup.

My device is not only extremely eicient, but is very economical as well, as it. will only feed while the enginel is in motion, and for this reason and because by its use the actual amount of oil needed can be quickly and accurately ascertained the result is a great saving of oil, absolutely none being wasted With my device.

Another advantage lies in the fact that by reason of the straight channel e the same cany be instantly and easily cleaned by thrusting a Wire therethrough should it ever become clogged.

By reason of the described vent-c the cup can be readily filled, as described, through the neck C and feed-hopper I, as the air in the cylinder will escape through said vent as fast as the oil from the hopper takes its place; and if any oil is forced through this vent c in the motion of the cup when in use, it will fall intoi'the feed-hopper I, andthus directly feed back into the cylinder. The opening z' in the bottom of the feed-hopper I is below the Walls h of the entrance to the channel e, andhence in the described operation of my device, when the same has been filled to the point of said opening t', the oil in the cup can only get into the channel e by the described motion of the cup, and will be directed by the curved guide F directly to the funnel-entrance to said channel, as indicated by the dotted lines in Fig. l, the pressure of the "air above the oilbeing increased by the described motion of the oil-cup, and serving to drive the oil down through the channel e, thereby making a sure and continuous feed, so long as the cup is in mot-ion.

In` case it is found more convenient to have the nipple E or part which screws onto the moving part of the engine in any other location than that shown, it will only be necessary to make a suitable connection between the channel e in the column E and the chan- I have not deemed it necessary to illustrate the same in the drawings.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. In an oil-cup, the combination of vthe cylinder with a Vertical column having a channel therethrough adjacent` to the Wall of said cylinder and a curved guide for directing the courseof. the oil to said channel, substantially as set forth.

2. In an oil-cup, the combination of the cylinder witha vertical column having a .channel therethrough adjacent to the Wall of said cylinder, the top of said column being below the top of said cylinder, and a cap having a feed-hopper projecting down into said cylinder below the entrance to the said channel,

whereby the said channel can only receive oil when the oil is forced above said channel-entrance, as by the motion of said cup, substantially as set forth.V

3. In an oil-cup, the combination of the cylinder with a vertical column having a channel therethrough adjacent to the wall of said cylinder, the top of said column being below the top of said cylinder, and a cap having a passage leading to said cylinder closed by a perforated plug, whereby there is always an air-'cushion above the oil in the cup, substantially as set forth.

4. -In an oil-cup, the combination of the cylinder with a vertical column having a cha-n- `nel therethrough adjacent to' the wall of said cylinder, an adjustable plate having an opening registering with said channel and surrounded by walls forming a funnel around said opening, said plate being adapted, by change of position, to more or less'closesaid channel, and a curved guide for directing the course of the oil into said funnel, substantially as set forth.

5. In an oil-cup, the combination of the cylinder with a vertical column having a channel therethrough adjacent to the wall ofsaid cylinder, and a curved guide for directing' the course of the oil, with a cap having a central feed-hopper and a central neck rising above said feed-hopper and communicating therewith, and a vent or lpassage between said' neck and the cylinder below, and aperforated plug filling the upper part of said neck, substantially as set forth. nel in said nipple; but this is so obvious that In testimony that I claim the foregoing I have hereunto set my hand, at Milwaukee, in the county of Milwaukee and State of Wis` consin, in the'presence of two witnesses.
