OIL CAN Filed Dec. 24, 1928 Emes? Com/m Inventor Attorney Patented Feb. 10, 1931 UNITED STATES PATENT oFr cs mnsrconunn, or SPOKANE, WASHINGTON OIL CAN Application filed December 24, 1928. Serial No. 328,202

C tools or machinery, and the device is constructed in a simple manner toinsure low cost of productlon, and may be operated with facility and convenience in lubricating otherwise inaccessible parts.

The invention consistsin certain novel combinations and arrangements ofparts involving the feed and discharge parts of the oil can as will hereinafter be more fully set forth and claimed.

In the accompanying drawings I have illus trated one complete example and a modification thereof of the physical embodiment of my invention wherein the parts are combined and arranged according to the best modes I have thus far devised for the practical application of the principles of my invention. It will be understood that changes and alterations may be made in the exemplified structures, within the scope of my claims without departing from the principles of my invention.

Figure 1 is a sectional view of an oil can of my invention of the pistol type having a trigger operating means. Figure 2 is a sectional view of a modified type of can, but using the same feed and discharge means, and Figure 3 is an'enlarged detail perspective view partly in section showing the cylinder construction. 1

In Figure 1 where the pistol type of trigger actuated device is illustrated, the can 1.

is of usual cylindrical construction and provided with a filling barrel 2 that is normally closed by the screw cap 3. The barrel is utilized as a handle or hand-grip when the oil can is being manipulated for lubricating purposes, and the can and barrel may be filled or partiall filled with oil that is to be pump ed or forced from the can.

Within the can an axially alined cylinder 4 is supported beneath a stationary partition 5 which extends transversely of the interior of the can and is fashioned with openings 6 for freedom of movement of oil at the opposite sides of the partition. The partition has an annular flange 7 in which theend of the cylinder fits, and at the opposite end of the cylinder a supporting yoke 8 is fixed to a head 9. on the cylinder. The diverging arms of the yoke are supported at the end of the can and a tie bolt 10 which has a countersunk head in the screw cap 11 of the can, is threaded into the head 9 so that the cylinder may be rigidly supported within the can as shown in Fig 111871'.

At one side of the cylinder near its end an intake tube 12 is connected, said tube projecting into the barrel 2, and at itsfree end this tube has a valve bushing 13 threaded thereon in which a ball valve 14 is enclosed and held to its seat by a spring 15. The ball valve nor-' mally closes the valve bushing against entrance of oil to the feed tube or intake tube,

and the ball valve is opened against tension of the spring by suction or air pressure when the operating parts of the oil can are manipulated. .As the ball valve is opened oil flows from the barrel into the tube and thence into the cylinder 4 after which the oil is-pumped from thegcylinder by means of the piston 16 into the spout 17 of the can. 5 1

The piston isof course located within the cylinder and the spout, whichextends longitudinally ofthe center of the can, is passed through an opening in the partition, and secured, as by screw threads, to the piston. The piston is fashioned with a valve bushing 18 that forms an extension of the spoutand also forms the cage for a ball valve 19, which through a springQO, normally closes the open end of the bushing, the latter being formed as a valve seat adjacent the inlet end of the feed. tube =12. When the device is manipu lated, a charge of oil is fed from the tube 12 into the cylinder and past the ball valve as the latter is 'removed'from its seat, and of The spout and its plston are adapted to be reciprocated, and they are moved in one direction against the tension of a spring 21 that is coiled about the spout and interposed between a fixed collar 22 and the partition 5,

. and the spring moves the spout and piston in 1 of the piston in the cylinder discharges the oil and the forward movement of the piston causes suction in the cylinder and tube so that the ball valve 14 is opened to admit a successive charge of oil :to the cylinder.

At its end exterior of thecan the spout is pnovicled With a reduced extension 2% that may terminate ina curved nozzle 25 by means of which otherwise inaccessible parts may be reached, or a nozzle 26, dotted lines Figure 1, may be used where oil plugs with ball valves are to be lubricated.

The piston and spout are manually retracted through the manipulation of a trigger 27 that is slidable in a bearing or guide 28 on the exterior of the can, and the trigger is pivoted -.to a lever '29 that extends transversely oat the spout and is pivoted thereon at 30. A link '31 forms the pivotal support for the lever and said link is pivoted on the can as indicated at 31c.

In Figure '2 the can 32 is provided with a cylinder 33 and the latter is supported from the partition 6 by a yoke 34, in addition to the tie bolt 100;. A'looped handle 35 is provided for the can and the spring pressed spout and piston are retracted manually by manipulation of the thumb lever 36 pivoted to the spout and also to the link 37 that is in turn pivotally supported at 38 on the can.

Having thus fully described my invention, What I claim as new and desire to secure by Letters Patent is a l. The combination with an oil can having a laterally extending filling barrel adapted to form handle, a cylinder within the can, a feed tube in the barrel connected to the cylinder and a spring pressed intake valve in the tube, of a piston in the cylinder having an intake valve, a spring pressed spout connected to the piston in the cylinder, and a trigger mechanism for retracting the spout and piston to discharge the cylinder.

2. An oiler comprising .a body portion, a handle connected thereto constituting an oil reservoir, a cylinder Within the body, means in the reservoir for conducting oil therefrom into said cylinder, a piston in the cylinder, a spout connected to the piston, and mechanism for reciprocating the piston and spout for withdrawing oil from the reservoir into the
