PROVISIONAL SPECIFICATION.
An Improved Pump for Ejecting and Spraying a Liquid from
a Vessel.
I, CHARLES WAGNER, of 162, West 27th Street, New York, in the County and
State of New York, United States of America, Machinist, do hereby declare the
nature of this invention to be as follows:-
The object of this invention is to provide a new and improved atomizing pump
which is comparatively simple and durable in construction and arranged to
positively and forcibly eject and spray a liquid from the vessel to which the pump
is applied.
The invention consists principally of a cylinder provided with a valved suction
pipe and a spring-pressed piston in the said cylinder and having its piston rod
forming the discharge pipe for the liquid.
The vessel containing the liquid to be sprayed or atomized is closed at its upper
end by a stopper in the form of a cylinder closed at its outer end by a screw cap.
From the bottom of the pump cylinder extends the suction pipe into the liquid
contained in the vessel and on the upper end of the said suction pipe is arranged a
suction valve which permits entrance of the liquid from the suction pipe to the
cylinder but prevents the liquid entering the cylinder from passing down the
suction pipe. In the cylinder is fitted to reciprocate a piston mounted on a piston
rod forming a discharge pipe for the liquid from the cylinder, the said piston rod
being fitted to slide in the cap and carrying on its outer end an atomizer nozzle of
any approved construction. On the piston rod a suitable distance above the cap is
arranged a disc adapted to be taken hold of by the operator's fingers to impart a
downward sliding motion to the piston rod for the purpose hereinafter more fully
described. The piston is mounted loosely on the piston rod and is free to slide
thereon between collars secured on the piston rod above and below the top and
bottom of the piston. The lower collar is secured in place by a screw which closes
the bottom end of the piston rod, the said lower end being also provided with inlet
ports or apertures adapted to be closed by the piston when the latter
on the up
stroke and adapted to be opened by the piston when the latter is on the down
stroke, the piston then resting against the upper collar. A coil spring is contained
in the cylinder and bears with its upper end on the lower collar so as to hold the
piston and its piston rod normally in an uppermost position. The cylinder is
preferably made of metal, and it is preferred to apply thereon an elastic ring
before inserting it in the neck of the vessel.
The operation is as follows :― When it is desired to atomize the liquid contained
in the vessel, the operator places the vessel in the palm of his hand and holds it
with some of his fingers and at the same time places the fore finger and little finger
ou top of the disc. The operator then exerts with the fore finger and little finger
a pressure on the disc so that the piston rod is moved downward whereby the upper
collar is caused to press against the top of the piston and carries the latter downward
in the pump cylinder at the same time that the spring is compressed by the
downward movement of the bottom collar. The air contained in the lower end of
the cylinder at this time escapes through the now open ports the hollow pistou rod
and nozzle to the outer air. When the operator releases the pressure ou the disc
the spring forces the piston rod upward whereby the lower collar on said rod is

page_text: caused to close against the piston so as to close the ports and as the piston moves
upward it draws in the liquid from the vessel so as to fill the lower part of the
cylinder. On the next downward stroke exerted by the operator's fingers the
piston uncovers the ports so that the liquid contained in the cylinder flows through
the ports into the hollow piston rod to be forcibly ejected through the atomize:
nozzle. As soon as the operator releases the pressure on the finger disc the spring
returns the piston rod and its piston into an uppermost position, it being understood,
however, that when this return movement begins the piston rod is first moved to
cause the piston to close the ports before the piston starts on the return stroke or
upward movement. Now by the repeated pressing and releasing of the disc jets of
liquid are forcibly ejected through the nozzle to the desired place.
I do not limit myself to any detail of construction described, as it is evident that
individual parts may be varied without departing from the spirit of my invention.
It will further be seen that the device may be amplified by the addition of an air
compressor to compress air either on the piston or an auxiliary piston on the piston
rod, and to carry this compressed air through the nozzle to thoroughly atomize the
liquid ejected through the nozzle.
Although I have described my invention as an atomizer, it is evident that the
invention can be arranged for use as an oiler, or as a pump or other device, for
ejecting any desired liquid from a vessel.

COMPLETE SPECIFICATION.
An Improved Pump for Ejecting and Spraying a Liquid from
a Vessel.
I CHARLES WAGNER, of 162 West 27th Street, New York City, in the County
and State of New York, United States of America, Machinist 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 :-
The object of this invention is to provide a new and improved atomizing pump
which is arranged to positively and forcibly eject and spray a liquid from the vessel
to which the pump is applied.
The invention consists principally of a cylinder provided with a valved suction
pipe, and a spring-pressed piston in the said cylinder and having its piston rod
fortning the discharge pipe for the liquid.
The invention also consists of certain parts and details and combinations of the
same, as will be fully described hereinafter and then pointed out in the claims.
Reference is to be had to the accompanying drawings forming a part of this
specification, in which similar letters and figures of reference indicate corresponding
parts in all the views.
and
Figure 1 is a sectional side elevation of the improvement;
Figure 2 is a broken sectional side elevation of the piston and its piston rod;
Figure 3 is a sectional plan view of the improvement on the line 3-3 of
Figure 1.
The vessel A containing the liquid B to be sprayed or atomized, is closed at its
upper end by a stopper in the form of a cylinder C, closed at its outer end by a
screw cap D, as is plainly illustrated in Figure 1. From the bottom of the pump
cylinder C, extends the suction pipe E into the liquid B contained in the vessel A,
and on the upper end of the said suction pipe is arranged a suction valve F which

page_text: permits entrance of the liquid from the suction pipe to the cylinder, but prevents-
the liquid entering the cylinder from passing down the suction pipe.
In the cylinder C is fitted to reciprocate the piston G mounted on a piston rod if
forming a discharge pipe for the liquid from the cylinder, the said piston rod II
being fitted to slide in the cap D, and carrying on its outer end an atomizer
nozzle 1, of any approved construction. On the piston rod H, a suitable distance
above the cap D is arranged a disk H' adapted to be taken hold of by the
operator's fingers to impart a downward sliding motion to the piston rod H for the
purpose hereinafter more fully described. The piston rod H has a loose fit in
the cap D to allow air to pass into cylinder C and down the fine channel C int,
vessel A, as shown by the arrows in Figure 1.
The piston G is mounted loosely on the piston rod H, and is free to slide thereou
between collars H and H', secured en the piston 10d above and below the top an
bottom of the piston G. The lower collar H³ is secured in place by a screw H',
which closes the bottom end of the piston rod H, the said lower end being also
provided with inlet ports or apertures Ho, adapted to be closed by the piston G,.
when the latter is on the up stroke as shown in Figure 2, and adapted to be opene l.
by the piston when the latter is on the down stroke, the piston then resting again-t
the collar H, as illustrated in Figure 1.
A coil spring J is set in the cylinder C and bears with its upper end on the
collar H³, so as to hold the piston and its piston rod normally in an uppermost
position, as shown in Figure 1. The cylinder C is preferably made of metal, and it
is preferred to apply an elastic ring K, between the cylinder C and the neck of the
vessel, as indicated in Figure 1.
The operation is as follows:
When it is desired to atomize the liquid contained in the vessel A, the operator
places the vessel A in the palm of his hand and holds it with some of his fingers,
and at the same time places the fore finger and little finger on top of the disk H¹.
The operator then exerts with the fore finger and little finger, a pressure on the
disk H so that the piston rod H is moved downward, whereby the collar H' is
caused to press against the top of the piston G and carries the latter downward in
the pump cylinder C, at the same time that the spring J is compressed by the
downward movement of the fixed collar H³. The air contained in the lower end of
the cylinder C at this time escapes through the now open ports H, the hollow
piston rod H and nozzle I, to the outer air. When the operator releases the
pressure on the disk H', the spring J forces the piston rod upward, whereby the
piston G is finally engaged by the collar H³, so as to close the ports H³, and as
the piston moves upward, it draws in the liquid B from the vessel A, so as to fill
the lower part of the cylinder C. On the next downward stroke exerted by the
operator's fingers, the piston G uncovers the ports H, so that the liquid contained
in the cylinder, flows through the ports H into the hollow piston rod H, to be
forcibly ejected through the atomizer nozzle I. As soon as the operator releases
the pressure on the disk H', the spring J returns the piston rod and its piston into
an uppermost position, it being understood, however, that when this return
movement begins, the piston rod H is first moved to cause the piston G to close the
ports H before the piston starts on the return stroke or upward movement.
In this manner by the repeated pressing and releasing of the disk H¹, jets of liquid
are forcibly ejected through the nozzle I, to the desired place.
I do not limit myself to any detail of construction shown and described, as it is
evident that individual parts may be varied without departing from the spirit of my
invention. It will further be seen that the device may be amplified by the
addition of an air compressor, to compress air, either on the piston G, or an
auxiliary piston on the rod H, and to carry this compressed air through the nozzle I,
to thoroughly atomize the liquid ejected through the nozzle I.
Although I have described my invention as an atomizer, it is evident that the
invention can be arranged for use as an oiler, or as a pump or other device, for
ejecting any desired substance from a vessel.
