Specification Accepted, 20th Apr., 1888
I, EBENEZER WANZER RIDER, residing at Racine in the county of Racine and
state of Wisconsin, in the United States of America, Gentleman, do hereby declare
the nature of this invention and in what manner the same is to be performed to
be particularly described and ascertained in and by the following statement :-
This invention relates to Oil Cans and consists in the construction and arrangement
of its several parts as will be hereinafter fully described and pointed out in the
claims.
In the accompanying drawings,
Fig. 1 is a vertical section of an oil can with the present invention applied and
attached.
Fig. 2 is a vertical central section of the inner or central tube detached.
In these drawings like letters refer to like parts.
The oil can A, is made in any usual or ordinary way, preferably in the general
conical shape shown in the drawings. Centrally fixed within it, in or over the
aperture a, in the bottom, is the tube B, its upper end b, projecting above the top of
the can and terminating in the nozzle b¹.
has on either side a slot, which extends down to the partition diaphragm or disc C,
Just within the top a', of the can this tube
fixed within said tube about three fifths more or less of the distance from the bottom
of the can.
This disc is centrally perforated at c to allow the insertion of the upper
end of the plunger rod D.
On the screw-threaded end of this, which extends beyond the disc C, is secured by
nut e the disc or piston head E.
On the rod D, near its upper end and fitting closely within the tube B, and so as
o be pressed snugly against the disc C by the spring F, is the gasket or packing G.
This spring is preferably spiral and wound round the stem of the plunger-rod and
ecured at its lower end to the button H.
This button fits snugly within the lower end of the tube B, but yet so as to be
ully moved up and down therein, and preferably so as to be about Hush with the
ottom of the can.

page_text: The operation of this device is as follows:-
Inverting the can and placing the thumb upon the button H, on its underside, the
plunger-rod D is moved forward, carrying with it the disc or piston-head E, on its
end, the oil from the interior of the can having meanwhile flowed through the slots b³
into the end of the tube is, by the continued forward movement of the piston-head E,
forced out of the nozzle.
It will be noticed that since the slots 6 extend close up to the inside top of the can,
By means of the washer or
the vory last drop of oil can be forced out of the can.
gasket or packing G, any leakage at the point where the plunger rod passes through
By moving the button H, up
the fixed partition will be almost completely prevented.
and down, any desired amount of the oil in the can can be forced out of it no matter
how thick or cold it may be.
The spring F, will act to return the plunger rod to its normal position whenever the
pressure on the button H, is removed.
Having now described my invention what I consider now and desire to secure by
Letters Patent, is :
1. In combination with the oil can A, having an apertured bottom, the central
tube B, slotted in each side at 3, at a point just within the can top, and having the
fixed partition C, and the plunger rod D, provided at its end with the piston-head E,
and the spring F, on said rod substantially as described.
2. An oil can having an apertured bottom and a central internal tube slotted at its
end, a fixed diaphragm or partition and a plunger rod having a packing thereon and
provided at its end with a piston head and having a spring connected with it and
bearing it inward and moved forwardly by a button in the lower end of the tube,
substantially as set forth.
