I, WALTER CHILD of 149 Montgomery Street Sparkbrook, Birmingham in the
county of Warwick Oil Can Manufacturer do hereby declare the nature of this
my invention for IMPROVEMENTS IN THE CONSTRUCTION OF OIL FEEDERS FOR
LUBRICATING MACHINERY to be as follows:-
My invention for improvements in oil feeders, relate to the construction of those
articles whereby greater simplicity is attained, and fewer working parts needed,
these improvements chiefly relating to the construction and manipulation of the
valves for the emission of oil and the inlet of air.
At a convenient point in the spout of the feeder I make a joint, that is, the
spout may be said to be in two parts.
To the part connected with the body of the feeder I attach a valve seat for the
emission of oil, having its face or seat outwards.
At a point in the body of the feeder near to the handle, and in a convenient
position for the thumb to operate thereon I fix another valve seat for the admission
of air, having its face or seat inwards.
Each of these valve seats having a central hole somewhat larger than the valve
spindle or wire which passes through them, thus allowing in the one case a passage
for the emission of the oil, and in the other case a passage for the admission of air,
I also provide a spindle or continuous wire having at the one end, (the handle end
of feeder) a thumb knob or button. Near the thumb knob or button the spindle
passes through the air inlet valve, and at this part upon the said spindle or wire,
is mounted a valve which acts upon the air inlet valve seat; the spindle then con-
tinues through the body of the feeder and up into the spout, terminating outside
the valve seat in the said spout, having at its extremity a valve to act upon the
said valve seat.
Attached at one end to a convenient part of the said spindle or wire, and at the
other end to the body of the can or feeder, I place a spring which acts upon the
aforesaid valves, so as to always keep them pressing upon their faces or seats,
except when a counter pressure is applied to the thumb knob or button.

page_text: Thus it will be seen that both valves act simultaneously upon their respective
seats, and from my method and arrangement of construction there is no necessity
for any screw adjusting arrangement for the valves to act together, as the emission
valve is secured in its position from the outside when the air inlet valve is in its
place. The extreme or remaining part of the spout is then screwed on to the part
which forms the emission valve seat, covering the valve in so doing.

Improvements in the Construction of Oil Feeders for
Lubricating Machinery.
>
I, WALTER CHILD of 149 Montgomery Street Sparkbrook, Birmingham, in
the county of Warwick Oil Can Manufacturer do hereby declare the nature of
my invention for IMPROVEMENTS IN THE CONSTRUCTION OF OIL FEEDERS, FOR
LUBRICATING MACHINERY and in what manner the same is to be performed, to
be particularly described and ascertained in and by the following statement:—
This invention for improvements in oil feeders, relates to the construction of
these articles, whereby greater simplicity is attained and fewer working parts
needed than in similar feeders heretofore made, these improvements chiefly relating
to the construction and manipulation of the valves, for the emission of oil and the
inlet of air.
At a convenient point in the spout of the feeder, I make a joint, that is, the
spout may be said to be in two parts.
To the part connected with the body of the feeder, I attach a valve seat, for the
emission of oil, having its face or seat outwards.
At a point in the body of the feeder, near to the handle, and within easy reach
of the thumb, I fix another valve seat, for the admission of air, baving its face
or seat inwards.
Each of these valve.seats having a central hole, somewhat larger than the valve
spindle or wire, which passes through them, thus allowing in the one case a passage
for the emission of the oil, and in the other case a passage for the admission of air.
I also provide a spindle or continuous wire having at the one end (the handle end
of feeder) a thumb knob or button. Near the thumb. knob or button, the spindle
passes through the air inlet valve seat, and at this part upon the said spindle or
wire, is mounted a valve, which acts upon the said air inlet valve seat;. the spindle
then continues through the body of the feeder, and up into the spout terminating

page_text: outside the valve seat in the said spout, having at its extremity a valve to act upon
the said valve seat.
Attached at one end to a convenient part of the said spindle or wire, and at the
other end, to the body of the can or feeder, I place a spring which acts upon the
aforesaid valves, so as to always keep them pressing upon their faces or seats,
except when a counter pressure is applied to the thumb knob or button.
Thus it will be seen that both valves act simultaneously upon their respective
seats, and from my method, and arrangement of construction, there is no necessity
for any screw adjusting arrangement for the valves to act together, as the emission
valve is secured in its position from the outside, when the air inlet valve is in its
place. The extreme or remaining part of the spout is then screwed on to the part
which forms the emission valve seat, covering the valve in so doing.
I will now further describe this my said invention by the aid of the accom-
panying sheet of drawings upon which are figures and letters of reference, and
upon which like letters refer to the same thing throughout.
Fig. 1 is an elevation of an oil feeder made according to this my said invention.
Fig. 2 is a sectional elevation of Fig. 1, shewing the internal arrangement, a, is
the emission valve seat serving also by means of screw at b, to connect the outer
end of spout c, to the inner end or part of spout (l. It will be seen that the valve
seat is upon the outside, so that when the outer part of the spout c, is removed,
any irregularity in the working of the valve, can at once be detected and put
right.
At a suitable point in the body of the feeder, I fix the air valve seat e, with its
face inside the feeder; fis the valve spindle, which is continuous from the valve g,
to the thumb knob or button h, carrying also the air valve i.
One end of a spring k, is attached at 7, to the valve spindle, the other end of the
said spring being attached to a suitable point in the body of the feeder at m, in
such a manner, as that the said spring tends always to press the valves g and i,
upon their faces simultaneously.
At suitable places such as n and o, I provide necessary guides for the valve
spindle, to control its movement and bring the valves g and i, to bear fair upon
their faces.
A sufficient amount of difference in size is provided, between the size of the
valve spindle, and the hole in the valve seats a and e, through which it passes to
allow (in the former case) the flow of oil, and (in the latter case) a passage for air.
The valves g&i, may if required be provided with leather, or other suitable
washers upon their faces.
In other respects than herein described the feeder may resemble those of ordinary
manufacture, and vary in design to suit pleasure.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is :-
1st. The construction of oil feeders, having one continuous valve spindle to
carry the emission and air valves, and acted upon by a spring similarly as described
herein and shewn upon the drawings.
2nd. The construction of oil feeders having an emission valve and seat, with its
face outwards, similarly as shewn at a & g, Fig. 2, upon the drawings.
