Description

, joint, which would obvlate or To all 'whom t may concern:

novel means for delivering oil under pressurefrom an oil can so that the tlow of the oil is augmented and forced to the roper point for use; the said invention aving for its further object the provision of novel means for controlling the discharge of the oil from the can, the said means including a valve which is in such position to the valve seat that when it is moved from engagement with the seat, the passage from the oil can to the discharge tube is unobstructed and this is advantageous for the reason that the full pressure of the air within the oil can may be exerted on the oil and there will be no valve stem or other impediment in the passage.

A still further object of this invention is to provide an oil can, the arts of which are readily disconnected so t at the valve and valve seat are accessible for purposes of repairing parts orrenewin parts which may use Aand a tight preventthe become unpaired ihroug leakage of oil or air, ma be maintained between the said valve an valve seat.

A stillfurther object of this invention is to provide novel means for connecting the oil conduit to the can so that the same may be removed and renewed when any part of the controlling system is impaired.

With the foregoing and other objects in 4- view, the invention consists in the details of yconstruction and in the arrangement and lcombination of parts to be hereinafter fully set forth 'and claimed.

In describing the invention in detail, reference will be'had to be accompanying drawings forming part of this specification in which the invention is` illustrated b tical sectional view of an oil canem the' invention.

In this drawin removed for the purpose of supplying oil to the interior of the can. Near the bottom tpeoi'eatlon of Lettera Patent.

of the can, there is a branchpipe 3 havin a web 4' constituting a valve seat, the sai web having an a erture therein for the passage of air to t e can. The valve seat is engaged by a valve` 5 threaded in the end of the pipe A3 so that it may be moved with relation to the valve seat of the web 4. A pump barrel 6 forms a continuation ,of the assf from the pump arrel to the pipe 3 w en the valve 5 is unseated, it bein understood that when proper pressure has een acquired in the 011 can, the valve may be closed to prevent escape of the said air. There is an air pumping piston 9 in the pumping cylinder and a' rod 10 extends through the cap 11 of the pump cylmder so `that when the piston 9 is reciprocated, air is forced into the can' or receptacle 1, and, as stated, when the roper pressure is attained, the valve is closed).-

The top of the can has an externally threaded flange 12 which surrounds an openmg 13 in the top of the can and a spout or discharge duct 14 has a threaded connecupper portion thereof. The cylindrical portion 16 is externally threaded as at 1 8 and internally threaded as at 19. The threads on the internal wall are engaged by threads of a valve s'eat 20, which valve seat has a duct 21 therethrough for the passage of oil and the lower end of said valve seat is engaged by a valve 22 carried by the valve stem 23 which valve stem is slidable in the cylindrical portion of the duct 14 and projects through the reduced end 17 of said cylindrical portion. The valve is held normally lseate by a spring 24 which encircles the valve stem and lbears against a shoulder 25 of the cylindrical portion of the duct 14 and against a shoulder 26 formed on the :5 .valvel stem. The valve 22 is removably apg, 1 denotes the reservoir.' or'can proper having a cap 2 Kwhich may be plied to the valve stem and is held in place byascrew 27. The kvalve may be manipulated or. unsea'ted by pressure on the lever 28 which by the pivot 29 is connected to the lower end of the valve stem and said lever is furthermore pivoted to a lug 30 on the external surface of the duct or member 14.

The spout 31 of the oil can has its lowery end provided with a flange 32 as shown and this flange rests against a gasket 33 on the outer end of the valve seat.l The fiange of the spout is held in engagement with the gasket by a ring nut 34 having a flange 35 engaging the flange of the spout and by the threads 36 engaging external threads of the cylindrical portion of the duct or member 14.

By reason of the construction just described, it will be observed that the spout may be expeditiously or 'conveniently removed frcm the valve seat and furthermore that said valve seat may be removed by reason of its threaded connection with the cylindrical ortion of the duct, and further'-V more that t e valve stem and valve may be) taken-from` the cylindrical portion by rea-' son ofthe clearance afforded by the removal of the valve seat.

It will be apparent also that the Whole of the oil discharging apparatus may be removed from the can by disjointing the parts which are connected tov the flange `at the top of the oil can.

From an inspection of the drawing, it will be apparent that when the valve is drawn down, free passage is afforded between the valve and valveseat and there is no valve stem or other impedimenthto the free flow of the oil under the influence of the pressure within the can.

I elaiml In an oil can, a receptacle, means for supplying air thereto, an oil discharging means comprising a duct having an extension depending into the receptacle, means for connecting the ductto the oil can, a cylindrical extension forming a continuation of the duct, said cylindrical extension having a reduced lower end, a valve stem slidable therein, means for holding the valve stem normally elevated, a manually operated device'for actuating the valve stem, a valve seat removably secured to the upper end of the cylindrical ortion and resting on said cylindrical portion, a spout resting on the upper end of the valve seat, and a nut engaging the said cylindrical portion and bearing against the spout for holding it on the seat.

In testimony whereof, I hereunto affix my signature in the presence of two witnesses.
