page_text: I, JOHN CAMPBELL, of the firm of Campbell and Harrison, Upper Castle Street
Shed, Bradford, in the County of York, Wool Comber, do hereby declare the nature
of this invention to be as follows:-
This invention has for its object the construction of an automatic apparatus
by which the wool or other fibre, after having been washed, is more thoroughly
and effectually oiled, by a continuous spray, than can be accomplished by oiling
apparatus of the ordinary construction.
I accomplish my object in the following manner. The oil is put into an air tight
cistern, fixed in any convenient position and fitted with suitable taps; through
the upper portion of the cistern I insert a pipe which projects a short distance into
the interior and is also connected by pipes to a double action air force pump or
blower of the ordinary construction. In the interior of the before named pipe
I place another pipe, one end of which extends to within a short distance of the
bottom of the cistern and the other, or outlet end, to about the end of the first
named pipe which may be fitted with a nozzle having one or more small holes
therein, the end of the large pipe within the nozzle being made nearly solid, a hole
being left for the egress of air from the pump or blower.
When the air pump or blower is put in motion, the air passing through the
before mentioned hole, creates a partial vacuum in the internal pipe, which,
combined with the air forced into the cistern, causes the oil to pass up through the
internal pipe to the outlet end where it comes into contact with the jet of air
blown through the before mentioned hole, by which the oil is distributed in a fine
and continuous spray on to the wool or other fibre.

I, JOHN CAMPBELL, of the firm of Campbell, and Harrison, Upper Castle Street
Shed, Bradford in the County of York, Wool Comber do hereby declare the nature
of this invention and in what manner the same is to be performed, to be par-
ticularly described and ascertained in and by the following statement :-
This invention has for its object the construction of an automatic apparatus by
which the wool or other fibre, after having been washed; is more thoroughly and
effectually oiled than can be accomplished by oiling apparatus of the ordinary
construction.
I accomplish my object in the following manner :-The oil is put into an air
tight cistern through the upper portion of which I pass a branch pipe, hereinafter
called the air pipe projecting a short distance into the interior of the cistern, one of
the outlets being connected with a double action air force pump or blower, and the
other, or outlet end, to a nozzle on the end of the pipe, the opening between the
nozzle and air pipe however, being by a very small hole. In the interior of the air
pipe I fix another pipe, hereinafter called the oil pipe, which extends from the
bottom of the cistern to the nozzle, the latter being bored out to receive the full
diameter of the oil pipe. Air being forced through the small bole by the action of
the pump or blower, or steam pressure applied to the branch pipe in like manner,
causes a partial vacuum in the oil pipe, which, combined with the air or steam
forced into the cistern causes the oil to pass through the internal oil pipe to the
nozzle, where it comes in contact with the jet of air or steam, and is emitted from
the nozzle on to the wool or other fibre in a fine and continuous spray.
In order that my invention may be more fully understood, I append a sheet of
drawings. Figs. 1 and 2 show respectively the side and front elevations of a
portion of an ordinary wool washing machine with my improved apparatus
attached, Fig. 3 is a view, partly in section, showing the cistern and air pump with
the connections between the two, Fig. a section through the nozzle and pipes
drawn to a larger scale, and Fig. one means of working the double action air
force pump, driven by a belt..
The letter A represents the oil cistern fixed at the top of the delivery end of an
ordinary wool washing machine, and is fitted with gauge glass A¹, filling cup, and
taps; B is a double action air force pump driven by the belt, pullies, and gearing, B
and C the air, pipe supplied with back pressure valve boxes D and D'. Between
the air pump B and cistern A at E, the air pipe. divides, one branch extending a
short distance into the oil cistern A and the other terminating at the nozzle F, the
connection between the two latter, for the egress of air or steam, being through
the small hole G. In the interior of this air pipe C, I fix the oil pipe H which
extends from the bottom of the cistern A to the nozzle F, the latter being bored
out to receive the full diameter of the said pipe.
The action of the apparatus as follows: When the air force pump B is set in
action, or steam applied, the air or steam as the case may be, passes through the
pipe C into the cistern A, and also into the nozzle F through the small hole G,

page_text: thereby creating a partial vacuum in the oil pipe H which, combined with the air
forced into the cistern A, causes the oil to pass through the internal pipe H to the
nozzle F where it combines with the jet of air or steam, and is blown through the
small hole G by which the oil is distributed from the nozzle in a fine and con-
tinuous spray, on the wool or other fibre which has passed through the squeezing
rollers and is being removed by the ordinary serrated revolving roller or opener J.
In order to regulate the amount of oil to be distributed on the wool, I attach to
the bottom side of the cistern A a small well K into which the pipe H terminates,
and form in the end of the latter a number of small holes L, and to the well K is
fixed a stuffing box through which passes a rod M attached to the piston P fitting
tightly into the pipe H. When too much oil is being used, the piston P is moved
upwards, thereby reducing the number of holes through which the oil can pass, or
when too little is being used more holes can be opened by lowering the piston,
thus regulating the quantity of oil to be delivered by the nozzle in a fine and
continuous spray,
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:
The combination of the pipes C and H with a cistern and double action pump,
blower, or steam pipe, substantially in the manner and for the purpose shewn and
described.
