- OIL CAN.

Application filed July 6,

' The present invention relates to oil-cans of the kind comprising a receptacle for the oil and a force and suction pump for forcing the oil out through a discharge pipe.

The primary object of this invention is to provide an il-can of this type which will not leak if the canbe placed in lying or inclining position (which might easily oc cur when the oil-can is stored forv inst-ancein the tool box of an autocar).

Another important object of the invention is to provide the discharge pipe in such a manner that said pipe can be swung or adjusted to any desired position in relation to the receptacle whereby "places which other- I wise are accessible only with difficulty readily can be reached by. the oil-can. I

These and other objects of the invention will be understood by the following description with reference to the accompanying drawing illustrating; one preferred embodi ment of the invention.

Referring to the drawing, Figure 1 shows a vertical section of theVoil-can. Figure 2 a side elevation of a portion of the oil-can, 3 a similar View with thedischarge pipe removedand Figures F6 views of de tails showing. the device by means of which the discharge pipe is joined to the receptacle. In the drawing, 1 denotes the receptacle fitted with a pump-cylinder] 2 preferably arranged in inclining position in said recepftacle which is provided with a discharge pipe 3 and a handle 4. The pistoniof the force and suction pump is denoted by 5 and the piston rod, having a button 6 on its outer end, by 13. The pump-piston 5 .is actuated by a spring 11 by which the piston, when .at rest, is kept raised and forced against the end of a tube-110 fastened to the cover 12 of the pump-cylinder and through which the piston rod passes. The air is permitted toenter into. the pumpcylinder through said tube in the. downward movement of the piston and to escape through it in the upward stroke thereof. The inlet for the oil is denoted by 7 and is c o edin an oil-tight manner bya screwcap 8. I

In order to permit the air to enter-into v the receptacle in the operation of the pump,

said enteringof air being necessary for forcing out the oil, a small bore or opening'is arranged in the top 35 of the receptacle, the said bore or opening receiving the end of one branch 14* of a rather thin U-sha'ped pip- 1925. Serial No. 41,774.

retiree pipe-connection 21 passes to the discharge pipe 3 which is united to said pipe-connectionby means of a joint permitting the ad justment of said discharge pipe in any desired position. Said joint comprises a memher 22 fastened to the bottom of the recep-- tacle. A central boring 23 in this member by means of ahole'24'going through the top wall'of the member'and the bottom of the receptacle communicates with the pipeconnection 21. A rotatable pin 25 of essentiallyv smaller diameter than that of the boring 23 is inserted into the latter leaving a passage for the oil in the interspace between the member 22 and the pin. One end of said pin is provided with threads receiving a nut 27 by means of which head 29 upon the other end of the pin is forced against an offset 30 at one end of the member 22, a packing ring 31 being preferably provided between the head 29 and the offset 30. The not 27 bears against an inwardly extending flange 32 at the opposite end of the member 22. a washer 33 and a packing ring 34: being preferably providedbetween the nut and the flange. hen tightening the nut 27 to a certain degreea shoulder -35 on the pin 25 will bear against the inner sideofthe flange 32. By

the device described both ends, of the member 22will be closed in an oil-tight manner at the sametime asrotation of the pin is permitted i The boring 23 of the member 22 communicates with a centralboring 36 in the pin 25 which boring extends fromthe interspace between the pin25 and the. member 22 to the interior of thehead 29 and communicates there with a boring 37 the axis of which is perpendicular to ,the axis of the boring 36. A member 38 having a central boring 38 disposed co-axially 'to the boring 37 and communicatingwith theilatter is revolubly 7 attached to the 'head29j. The member'38 is joined to the head 29 by a'scre'w of OU smaller diameterthan that of the borings 3'? ins inclining position. but? ifjan'y" smalleuantity and 38 The head 39 of said screw by means of a packing ring 40 bears against an inwardly extending flange 41 on the head 29. The threaded end of the screw or pin 39 receive: a nut e2 bearing against the outer side of the member 38. An oil-tight connection between the parts 29, 88 is effected in the following manner: On the head 29 there is provided a flange 43 projecting co-axially in relation to the boring 37 and surrounded by an annular recess it (Figure 5). This recess, in which a packing ring 4:5 is applied, fits to a flange 4L6 projecting from the member 38 and co-axially positioned in relation to the boring 38. hen the nut 42 is tightened the flange 46 will bear tightly against the packing ring 45. The member 38 (Figure 6') is formed with a threaded portion 47 having a boring 48 therein. The threaded portion 47 receives a nut 9 by means of which a flange 50 on the end of the discharge pipe 3 is forced against the outer end of the portion 47, A packing ring 51 may be provided between the flange 50 and the nut 49.

By these means the discharge pipe 3 is permitted to be rotated about its longitudinal axis a well as about each of the pivots 25 and 39. The pivot 89 permits the swinging of the discharge pipe in a vertical plane and the pivot 25 in any plane forming a right angle to said vertical plane. Due to this arrangement the discharge pipe can be adjusted to any desired inclining position which involves a great advantage in the lubrication of ditiicultly accessible places.

On the outer end of the discharge pipe 3 a screw-cap 52 or the like may be applied in order to prevent leakage of oil through said 1 e. p lwo studs 53 attached to the bottom of the receptacle 1 together with the member 22 form supports for the oil-can.

Supposing oil is present in the receptacle t the height indicated'in Figure 1. If now the pump-piston be moved downwards against the action of the spring 1.1 the oil previously sucked into the pump-cylinder will be forced out through the discharge pipe .3. lVhen the piston 5 is pressed up-' wards by the spring 11 a new quantity of oil is sucked through the canal into the pump-cylinder on the under side of the piston. Hereby a reduction of the pressure in the space above the oil within the receptacle will take place and as a consequence'air will be supplied into said space through the U-shaped piping 1a. The air thus supplied. obviously replaces the oil sucked into the pump-cylinder. Under ordinary conditions no. oil will. be able to escape through the-pip; evenif thecan be placed inflyfiifg gr etcil ha e redto th r i 'ins i f -w l pressetl' out into the receptacle at the ne;t;t :npward. stroke .of thc prstonjthe all which at the same time by the atmospheric pressure is forced into the'piping,

It will thus be understood that the oil-can is completely oil-tight at all parts where otherwise a leakage might easily take place. If on account of heat the volume of the oil be increased the air is permitted to escape from the space 35 through the pipe 14-. If such an escaping of the air were not possible the pressure within the receptacle would be increased and the oil forced out through the discharge pipe.

I do not limit my invention to the embodiment above described with reference to the drawing but'want to be free to vary the details thereof without departing from the spirit of the invention as defined in the appen d la ms- What I claim is 2- 1 In oil-cans, a receptacle. for the oil, a 5
