Be it known that l, LEXUS NV. HARDY, :i resident of Chicago, inthe county ot Cook. and State of Illinois, have invented certain new and useful improvements in Devices for Oiling Elevated Sheft-l'em'ings; sind l do hereby declare that thc following is zi. full, clear, sind exact description thereof, referencel being had to the accompanying drawings, and to the lett-ers of reference marked thereon, which form a partei1 this speciiezition.

This invention rele-ii te Oilers for oiling` elevated allait-bearings and the like; audit consists in the features and combinations hereinafter set forth. and pointed out in the appended claims.

Figure l is elougitudinztl Section showing my invention in the forni new believed to be the best adapted for general use. Fig. 2 is si longitudinal section showin g the invention in modified form. Fig. 3 is a longitudine-l section Showing tire general invention Wanting certa-in features present iii Figs. 1 and 2.

The cylinder A is'proyided with a. iillinghole a stopped with eplug c.' at its upper end, tube C is provided with am opening c neer its connection with the pieton l), while itsupper cud is provided with e hoek In the simple construction shown in Fig. 3 the piston D fills the 'cylinder A. The cylinder A. being filled with oilafnd the filling;H hole stopped by the plug, the end of the hook C' on the tube C is thrust into the cup of en elevated bearing and doWnwa-idpulling force isl applied to the handle B. Such pulling upon the handle dra-Ws tlic cylinder ilowii- Wardly while the piston remains stetionary,

2. An oiler for elevated bearings and the like, comprising a receptacle and pump mounted on the end of a pole or handle, the pump piston being connected with a protruding, longitudinally movable delivery tube which is provided with a hook adapted to be engaged with the cup or bearing to be sup plied, whereby, tirst., the oiler may be raised to engagement with the elevated bearing by the operator standing below, and, second, upon a downward pulling movement ot the pole or handle by the operator, the pump is operated. and the oil is expelled through the tube to the cup or bearing, substantially` as set 'foi-th.

3. In an oilerforelevated bearings, the coinbination of a receptacle closed at both ends and provided at its lower end with means for its attachment to a pole, a pump piston within the receptacle, and a delivery tube connected with the piston a nd prot ruding through the -upper end ot' the receptacle, said delivery tube being provided at its delivery end with a. hook adapted to be engaged with the cup or bearing to be supplied, whereby, the hook being so engaged, a downward pulling ioree applied to the receptacle causes the piston to expel oil through the delivery tube to the bearing.

et. An oilervi'or elevated shaft bearings, the 5o combination ot aI receptacle adapted to-be mounted on a pole, apump piston within the receptacle, a delivery tube connected with the piston and protruding through the upper end of the receptacle, said delivery tube ter- 5S Y ininating in a hook-formed spout at its upper end, the extremity of which is substantially in line with the straight portion of the tube, and a spring arranged to retract the delivery tubc, substantially as and for the pur- 6o poses set forth. I

5. An oiler comprising a receptacle closed at both ends, a handle secured to the receptaele, a separate piston pump secured within and at or near the bottom of the receptacle, a 65 delivery tube connected withthe pist-on of the pump and protruding through the top of the receptacle, said tube terminating at its outer end in a hook-formed spout, and a spring for retracting the delivery tube.

Il. ln an oiler, the combination of a receptacle closed at both ends, an apertured diaphragm secured wit-hinthe receptacle and provided with a downwardly projecting plug having a lengthwise passage through it; ahol- 7 5 low piston fitted to the plug and provided with a lateral opening which is covered by the plug except when the piston is retracted; a delivery tube connected with the bottom of the piston, said tube having an opening witli- So 'in the piston, prttruding lthrough the plug and also through the top of the receptacle, and having a hooleforined spout at its upper end, and ay spring for retracting the piston and delivery tube., substantially as .de- 85 scribed and for the purposes setl forth.

In testimony that I claim the foregoing as my invention l a i'tix my signature in presence of two witnesses.
