FEC,

To all whom it may concern:

Be it known that I, JOHN H. METHVEN, a subject of the King of England, and a resident of Ronald, in the county of Kittitas and State of lVashington, have invented' a new and useful improvement in Oil-Cups and Feeding' Attachments Therefor, of which the following is a specification.

My present invention relates generally to oil feeding devices, and more particularlyto oil cups and attachments therefor, the'combined operation of which effectively prevents the feeding of impurities with the lubricant and the construction of which obviates clogging up of the feed pipe by impurities in the oil within the cup.

Generally speaking l obtain these advantages by an arrangement which includes an oil cup in whichthe feed pipe is extended to a point adjacent the upper end of the cup, together with a water'tank which in operative position provides the necessary pressure to lift the body of oil to the receiving end of the feed pipe, and manipulation of which to inoperative-position permits of the draining of the water andrefilling of the oil cup.

More especially my invention resides in the construction, arrangement, and operation of parts as shownin the accompanying drawing to which-reference is made in the following specification embodying a description of the invention.

In the drawings:

Figure 1 is a view partly in side elevation and partly in section, illustrating vmy improvements Figs. 2 and 3 are detail sectional lviews taken respectively on lines 2v2 and 3 3 of Fig. 1;

Fig. 4 is a detail section through the fill* ing cap and relief port of the water receptacle.

Fig. 5 is an edge view of the supporting bracket.

Referring now to these figures, my invention provides an oil cup generally indicated at 10, having its feed pipe 11 provided with sight. feed glasses'12, as seen particularly in Fig. 3, and with a cutoff valve 13, and having its upper end extended upwardly within the oil cup 10 to a point adjacent the upper end of the latter, and threaded at 14.

The cylindrical portion 15 of the oil cup is of glass and its top 16 has an outer annular flange 17 engaging the upper edge of the cylindrical glass 15 and is provided with an j Specification of Letters Patent.

innerdepending threaded ring 18 supported by arms 19 for engagement upon the threaded upper end 14 of the feed pipe, the central portion of the top 16 having a threaded nipple on which is screwed a filling cap 2O adjacenty the` upper extremity of the yfeed pipe, upon which latter is a shield 21 vof cone-shape, inverted in spaced relationto the upper end of the pipe andconnected thereto by-a reticulated cylinder 22 so as to permit the lubricant within the body of the oil cup to nd its way upwardly over the upper end of the feed pipe and downwardly into the same, and at the same time force the lubricant in such movement to pass through the reticulated material by means of which impurities are rejected.

- Adjacent its lower end of the oil cup 10 has a 'water inlet tube 23 extending and opening therein, to theouter end of which water inlet tube is rotatably connectedvthe end of the tube 24:, the connection being madeby packed joint 25 to obviate leakage. The 4tube 211- forms the angular end of a verticallyv disposed water pipe 2G leading from an enlarged water container 27, in the present instance of substantially a sperical shape, that end,v of the tube 24: opposite the packed joint 25 having a conical recess in its terinini'ls receiving the similarly shaped end of a bearing pin 28, the latter threaded with in the central bearing 29 of a supporting bracket 30, so as to thus permit of rotation of the water receptacle 27 upon the longitudinal axis of the tube 24 from uppermost position above the oil cup 10 to lowermost position below the same and vice versa.

The bracket 30 which generally extends in an upright position and is secured at the outer end of a supporting stem 31 has an upper and lower angular arm 32 and 33 respectively, forming stops for the pipe 26 of the wat-er receptacle, and provided with pivoted catches 34- to engage the said pipe for holding the water receptacle in upper and lower positions.

The water intake pipe 23 is preferably provided with a cut-off valve 35 so that when the water receptacle 27 is turned down to the lower position and the water allowed to drain into the vessel and out of the oil cup previous to refilling the latter, the said valve may be closed when the oil is poured into the cup upon removal of the filling cap 20. In this operation the water is drained back into the water receptacle t0 the level of the innerl upturned end of the watertube 23 of the oil cup and the latter may be then Ydrained `of the remaining water including residue by means of adrain nipple 36 normally closedby a cap 37. Y v

As above stated, the oil is introduced after lowering of the water receptacle to permit the water to flow back thereinto from 'the oil cup, vand in case the water remaining in theoil rcup is drained out, the lower portion of the cup is filled with water to the level of the inner end of the tube 23 before the supply of oil is introduced through the filling aperture. .c

It isY obvious that my invention provides an'oil filling device of this type inrwhich refilling of the oil cup may be accomplished readily and quickly at all times, the supply of oil standing in the feed pipe and controlled' byits regulating valve 13, taking care of the proper lubrication of the parts in connection with which the invention is utilized, during the short spaceof time required for refilling. f

It is furthermore obvious that the inveni tionprovides a comparatively simple and inexpensivev device of this type, durable in its i nature kand capable of effective and eicient use for the intended'purposes.

Thel container 27 before referred to may have a filling cap and relief port 27a, as seen in Fig. l, provided with a check valve 27h to prevent outflow of water.
