OIL CAN,

AFPUCATION FILED JULY 19. 1919.

Patented Feb. 21,1922.

IN VEN TOR.

A TTORNE Y.

To all wiwm it may concern Y Be it known that I, EDWIN JoHANsoN, a citizen of the United States, residing at Tg o in the county of Latah and State of Eda. e, have invented new and useful Improvements in ()il Cans. of which the following is a specification.

This invention relates to improvements in cit cans, and the principal object of the invention .is to provide means for causing the oil to flow from the can upon the manipulation of the valve Another object of the invention is to provide a spring-pressed plunger for forcing the oil from the can and means for holding the plunger in retracted position when it is desired to till the can or for any other reason.

The invention also consists in certain other features of construction and in the combination and arrangement of the several parts, to be hereinafter fully described, illustrated in the accompanying drawings and specifically pointed out in the :appended claims.

In describing my invention in detail. vei erence will be had to the accompanying drawings wherein like characters denote like or corresponding parts throughout the several views, and in which 1- Figure 1 is an elevation of the invention with parts in section;

Figure 2 is a cross section on line 2-12 of Fi re 1; I

nignre 3' is a cross section through the valve;

Figure 4 is a detailed view of the handle ang stand; i re 5 lifter? In these views 1 indicates the body of the can which is provided with the usual spout 2 which is removably secured to the can by the screw top 3. The bottom 4 of the can, is screw-threaded t0 the body as shown hit fi. Within the body is located a piston. 6, the rod 7 of which extends is a detailed view oi the valve through the bottom 4, a packing gland 8 being provided tor preventing leakage. A coiled spring 9 is located between the piston and bottom and tends to force the piston towards the top of the can so as to force the oil in the can out of the spout.

The spout is provided with means for closing the same to prevent the discharge of oil until wanted. Such means consists of a Specification of Letters Patent. Patm tetfi Fell 21, 1922,

casing 10 extending crosswise of the s out, as shown and having one end closed an the other end open. A valve 11 closes the end of the spout. at the screw top 3 and the stem 12 of said valve passes th'rouglrthe lower part of the spout into the casmg'lO where it provided with an enlarged. head 13. The open end of the casing 10 is closed by a stopper 14 through which passes a stem 15 which is provided with an enlarged head 16. This stem is normally held in its outer position by means of the coiled spring 17 having one end pressing against the packmg gland 18 and its other end against the head 16. The inner end of the stem engages the forked end of a valve lifter 19 which is carried by a clevis 20 mounted on the stopper and the other forked end of the lifter engages the head 13 of the valve stem. It will thus be seen that the spring 17 \villhold the valve in closed position with the stem 15 in its outer position. The can is provided with a handle 21 provided with a finger hold 22 so located that when the same is gripped by the hand the thumb will be in position to press upon the head 16 of the stem 15 to push the same inwardly and thus rock the valve litter to move the valve oil its seat and thus open the spout. The pressure of the spring 9 upon the piston will force the oil through the spout. When enough oil has been dischargedthc thumb is removed from the head 16 so that the spring 17 will return the parts to normally position and close the valve.

The stem 7 of the piston is provided with a shoulder 23 to limit the upward movement of the piston and the rod also carries at its outer end a combined handle and stand 24 by which the piston may be lowered by hand and which forms a rest for the can.

When the can is to be filled or it is desired to hold the piston at the bottom of 'tiifiie can, the same may be lowered by hand and locked by means of a catch 25 slidably mounted on the bottom of the can engaging a hole 26 in the stem.

in order to prevent a vacuum being formed in the rear of the piston I provide a hole 27 in the bottom of the can which is closed by a flap 28.

It is thought from the foregoing descrip tion that the advantages and novel features of my invention will be readily apparent.-

I desire it to be understood that I may make changes in the construction and in the combination and arrangement of the several parts, provided that such changes tall within the scope of the appended claims.

Vi hat l claim is: 1. EhClQVHTQ of the character described eoinprising a body, a spout provided thereon, :1

' and the remaining end open. a valve closing the ends of the spout and the screw top and the. stem of said valve passing through the lower part of spout into the casing where it is provided with an enlarged head. a stopper (losing the open end of the casing and a stem passing therethrough and having an enlarged head provided thereon. a eoil spring adapted to hold said stem in its outer position, a packin gland pressing one end of said spring and the enlarged head pressing against toe. remaining end, av valve litter having its forked ends engaged by the inner ends of said stem and a elevis carrying said lifter and the former being mounted on the stopper, and the other forked end of the lifter engaging the enlarged head otthe, valve stem.

2. A device of the eharaeter deserioed coniprising a body, a spout provided thereon, a

screw top removahly securing said hodv to the can, the bottom of the can heing sen-0w threaded to the body, and a piston loeated Within said hod} and having its rods extending through the bottom thereof. a coiled spring closing the spout consisting of a easing ext-ending crosswise ot' the spout and haying one end closed and the remaining end open, a valve closing theends of the spout and the screw top and the stem of said valve passing through the lower part of spout into the casing where it is provided with an enlarged head. a stopper (losing the open end of the casing and a stem passing therethrough and having an enlarged head pro vided thereon, a (fOll spring adapted to hold said stein in its outer position. a paeking' gland pressing one end of said spring and the enlarged head pressing against the remaining end. a valve lifter having its forked ends engaged by the inner ends of said stem and a elevisezn'rving said lifter and'the former being mounted on the stopper. and the other lorlted end ol the lifter engaging the enlarged head of the 'alve stem. :1 shoul der provided on the stem of the piston and a roinlnned handle and van carried by the,

rod at its outer end a (-ateh slidahly mounted on the hottoni-ol't the can and engaging a hole tornied in the stem.

in testimony whereof I allix my signature.
