PROVISIONAL SPECIFICATION.
Improvements in Oil Cans.
I, NOAH GIFFORD POMEROY, of 101, Humphrey Street, New Haven, in the
County of New Haven, and State of Connecticut, United States of America,
Clock Maker, do hereby declare the nature of this invention to be as
follows:-
My invention relates to an improvement in oil cans, and has for its object
especially to provide an oil cau capable of being safely carried in the pocket
without any of its contents spilling and also to so construct the can that it will be
especially adapted for use in oiling the bearings of bicycles and other like
machines or vehicles, the nozzle of the can being so formed that it will clean the
oil apertures from any dust or dirt contained therein and in advance of the flow of
oil, thus ensuring the oil reaching the parts actually in frictional engagement.
Another object of the invention is to construct an oil can of the character described
in a simple durable and economic manner.
The invention consists in the novel construction and combination of the several
parts, as will be hereinafter fully set forth.
The body of the oil can is preferably made in the shape of a cylindrical casing
closed at its lower end and provided at its upper end with an interiorly threaded
collar made integral with, or securely attached to, the casing. Beneath the
collar within the casing is located preferably a spiral or coil spring and in the
threaded aperture of the collar is screwed a nozzle preferably made conical at its
outer end and formed with an annular rib adjacent to said end. A piston or
cleaning rod is loosely fitted in the nozzle which extends through it some distance
beyond its outer end. To the inner extremity of this rod is fastened a disc made
of less diameter than the interior of the casing which disc bears by its under face
upon the upper end of the spring contained in the casing, the upper face being
preferably provided with a cushion acting as a valve to normally close the lower
or inner end of the nozzle. To the nozzle, preferably just above its threaded
portion, is attached a disc provided with a gasket which is of a diameter essentially
the same as the interior diameter of the casing. By this means any leakage of oil
from around the nozzle is rendered almost impossible, and when the inner valve
disc is in its normal position the oil is effectually prevented from passing out
through the opening in the nozzle. In order to ensure a total absence of leakage
when the can is carried in the pocket, it is provided with a cap containing an
interior plug, of cork or like material, provided with a channel of sufficient length
to receive the projecting end of the cleaning rod or piston when the valve disc is in
the normal position, the mouth of the channel being flared to receive the outer
end of the nozzle. The cap fits neatly over the body of the can and is prevented
from being pressed too far downward by an annular projection formed upon the
exterior surface of the can for the purpose.
When it is desired to lubricate a bearing, the cap is removed and the cleaning
rod is inserted in the oiling aperture and is manipulated to clear said aperture from.
dust or foreign matter that may have collected. When this has been accom-
plished and the surfaces to be lubricated have been reached pressure is exerted
upon the rod whereupon its attached valve disc compresses the spring contained in
the can and uncovers the opening in the nozzle so as to allow the oil to flow
freely past the disc and through the said opening, only in the quantity desired, to
the parts to be lubricated. The moment the can nozzle is withdrawn from the
oiling aperture, the spring returns the valve disc to its normal position closing the
opening in the nozzle and forcing the rod outward to be again brought into service

page_text: or to enter the channel in the cap. It will be observed that the piston or
cleaning rod is so constructed as to avoid absolutely any waste or leakage of oil.
The can is exceedingly simple and durable and may be economically
manufactured and it may also be carried in the pocket with safety, as the oil
cannot escape.

COMPLETE SPECIFICATION.
Improvements in Oil Cans.
I NOAH GIFFORD POMEROY, of 101 Humphrey Street, New Haven, in the
County of New Haven, and State of Connecticut, United States of America,
Clock Maker, 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 :-
"
My invention relates to an, improvement in oil cans, and has for its object
especially to provide an oil can capable of being safely carried in the pocket
without any of its contents spilling, and also to so construct the can that it will be
especially adapted for use in oiling the bearings of bicycles and other like
machines or vehicles, the nozzle of the can being so formed that it will clean the
oil apertures from any dust or dirt contained therein and in advance of the flow of
oil, thus insuring the oil reaching the parts actually in frictional engagement.
Another object of the invention is to construct an oil can of the character described
in a simple, durable and economic manner.
The invention consists in the novel construction and combination of the several
parts, as will be hereinafter fully set forth and pointed out in the claims.
Reference is to be had to the accompanying drawings forming a part of this
Specification in which
Figure 1 is a perspective view of the body and cap of the oil can, one removed
from the other;
Figure 2 is a central longitudinal section through the body of the oil can and its
cap; and
Figure 3 is a detail view of the cleaning plunger.
Like figures and letters of reference denote like parts in all the views.
The body A of the oil can is preferably made in the shape of a cylindrical
casing, closed at its lower end and provided at its upper end with an interiorly
threaded collar 10, the said collar being integral with or securely attached to the
casing.
Beneath the collar, within the casing, a spring 11, is located, which is preferably
a spiral or coil spring; and in the threaded aperture of the collar the threaded
portion of the nozzle 12 of the can is screwed. The nozzle at its outer end is
preferably made conical, and adjacent to its conical section an annular rib 13 is
formed.
A piston or cleaning rod 14, is loosely fitted in the nozzle, and extends through
it and some distance beyond its outer end. At the inner extremity of the piston or
cleaning rod a disc 15, made of less diameter than the interior of the casing is
fastened, which disc has a bearing upon the upper end of the spring 11 at its under
face, the upper face being preferably provided with a cushion 16, acting as a valve
to normally close the lower or inner end of the nozzle, as shown in Figure 2. The
nozzle is preferably provided just above its threaded portion with an attached
disc 17, provided with a gasket 18, the said gasket being of a diameter essentially
the same as the interior diameter of the casing. By this means it is rendered
almost impossible for any oil to leak out from around the nozzle; and when the

page_text: inner valve disc 15 is in its normal position, oil is effectually prevented from passing
out through the opening in the nozzle.
In order to ensure a total absence of leakage when the can is carried in the
pocket it is provided with a cap B containing an interior plug 19, of cork or like
material, provided with a channel 20 of sufficient length to receive the outer
projecting end of the cleaning rod or piston 14 when the valve disc is in the
normal position, the mouth of the channel being flared to receive the outer end of
the nozzle, as is likewise best shown in Figure 2. The cap fits neatly over the
body of the can, and is prevented from being pressed too far downward by forming
a projection upon the exterior surface of the can for the purpose.
In operation, when it is desired to lubricate a bearing, the cap is removed and
the cleaning rod 14 is inserted in the oiling aperture and is manipulated to clear
said aperture from dust or foreign matter that may have collected. When this has
been accomplished, and the surfaces to be lubricated have been reached, pressure is
exerted upon the rod 14, whereupon its attached valve disc compresses the spring 11
contained in the can, and uncovers the opening in the nozzle, so as to allow the oil
to flow freely past the disc and through said opening, only in the quantity desired,*
to the parts to be lubricated. The moment the can nozzle is withdrawn from the
oiling aperture, the spring returns the valve disc to its normal position, closing the
opening in the nozzle and forcing the rod 14 outward to be again brought into
service or to enter the channel in the cap. It will be observed that the piston or
cleaning rod is so constructed as to avoid absolutely any waste or leakage of oil.
The can is exceedingly simple and durable and that it may be economically
manufactured, and further that it may be carried in the pocket with safety as the
oil cannot escape.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. A tubular oil can having an internally threaded collar 10 in its outer end, a
threaded discharge tube screwed thereto, a disc 15 within the can and having a
rod 20 projecting out through the tube, the spiral spring 11 bearing against the
bottom of the tube and against the under side of the disc, and the removable
cover B enclosing the discharge nozzle, substantially as set forth.
-2. In an oil can, the combination, with the body thereof adapted to contain the
oil, a nozzle and a spring-pressed valve located below and adapted to close the
nozzle opening, of a rod attached to the valve and extending loosely through and
beyond the outer end of the nozzle, and a cap adapted to close the nozzle end of
the body, provided with a plug or filling channeled to receive the projecting end
of the valve rod and the outer extremity of the nozzle, as and for the purpose
set forth.
