1 Claim.

This invention relates to a detachable connection for auxiliary reservoirsv and is especially adapted to be used in connection with a lubri-v cation with a lubricating system for an internal 5. combustion engine as disclosed in the application of Vernon W. Thompson and Burt N. Pierce, led December 8, 1930, Serial No. 500,928, the object being to provide means for connecting the auxiliary reservoir to the oiling system Without breaking the connection, thereby allowing the auxiliary reservoir to be connected and disconnected to the oiling system.

Another and further object of our invention is to provide a gauge in connection with the connecting member, whereby the amount of oil within the auxiliary reservoir can be ascertained at any time.

A still further object of the invention is to provide a connection in the form of a sectional cap, one section being movable in respect to the other so that the threaded section can be screwed down onto the threaded neck of the receptacle, allowing the other section to remain stationary.

Other and further objects and advantages of the invention will be hereinafter set forth and the novel features thereof defined by the appended claim.

In the drawing,

Figure 1 is a perspective View of a portion of a can showing the application of our improved construction of connection thereto;

Figure 2 is a vertical section through a portion of a can showing our improved connection; and

Figure 3 is an enlarged vertical section through the `connection.

Irf the construction of lubricating system described in the application of Thompson and Pierce, we employ an auxiliary reservoir in the 40 form oi a can for supplyingY a lubricant to an oiler, which in turn supplies oil to the induction pipe of an internal combustion engine, said supply being controlled by the vacuum in the intake whereby lubricant is fed to the valves and the combustion chamber of an internal `combustion engine.

In the form of connection as herein sho-wn when used in connection with an auxiliary reservoir in the form of a can 1 having a threaded neck 2, we provide means for connecting the pipe system after a can becomes empty without breaking the connections or injuring the connections in any way leading to the oiler.

In carryingout our invention, we employ a sectional cap formed of an internally threaded sleeve 3 and a disc 4, the sleeve being provided at one end with an annular flange 5 having a beveled portion 6 cooperating with the beveled periphery 7 of the disc 4 so as to form a tight joint between the two Vsections when the sleeve is screwed down on the neck of the can.

As herein shown the neck 2 of the can is provided with an annular flange 8 at its upper end which is engaged by the bottomface of the disc 4 so as to form a seat therefor so that when the sleeve 3 is screwed down, the disc will be forced tightly in position on the iiange of the neck and a tight connection will be formed between the sleeve and disc. This allows the sleeve to be rotated in order to insert or remove the same from the neck of the can Without disturbing the connection to theoiler as will be hereinafter fully described.

The disc has formed integral therewith an elbow 12, said elbow having a coupling 13 for connecting the pipe line 14 to the oler of the lubricating system to which the auxiliary reservoir is attached whereby the pipe line leading to the oiler will remain in its original position when the sleeve 3 is rotated so as to detach the sectional cap from the reservoir.

The elbow portion of the disc 4 is internally threaded and in said position the threaded upper end 10' of a pipe is mounted, which extends down into the receptacle and terminates short of the bottom thereof so as to allow the lubricant to be withdrawn from the bottom of the can and to prevent air from being conveyed with the lubricant` to the oiling system to which the device is adapted to be attached.

The disc 4 is also provided with a threaded opening 15 in which a tube 16 is mounted in which is slidably mounted a gauge `rod 17 calibrated to indicate the quantity of oil within the container or receptacle,l said rod terminating in a curved portion 18 atits upper end forming a handle by means of which it can be raised or lowered or de tached from the reservoir in order to determine the amount of oil within the same. The rod carries a cap 19 which seats on the upper end of the tube 16 so as to support it in its proper position.

From the foregoing description it will be seen that we have provided Van auxiliary reservoir with a sectional cap carrying a gauge and means for connecting the same to a pipe line leading to an oiler so that the pipe line can be connected to and a new can inserted and attached to the lubricating:

system without any danger-'ofiniing pipe lines leading from the auxiliary reservoir ytothel oiling system. l

What we claim is:

A reservoir for lubricatingv for internal combustion engines comprising a receptacle having an externally threaded neck terminating in a at end portion, aflat disc mounted on the flat portion of said neck having an outwardly beveled edge and provided with a tubular projection having a coupling, an internally 'threaded cap mounted on said neel; having an annular flange provided'witlffan undercut beveled portion cooperating with the beveled edge of said disc to allow said members to be rotated in respect to one another, said disc portion being 'adapted to be clmged'tli'ereon in adjusted position by said cap pion and a pipe line connected to the coupling @if eel@ @ist Perdon;
