Improvements in Liquid Dispensing Apparatus.
I WILLIAM MILES FOWLER of No. 15 Vaudewater Street in the City of New
York in the County and State of New York, United States of America, Manu-
facturer, 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 improvements in liquid dispensing apparatus in which
different, predetermined quantities may be drawn from a receptacle, and a register-
operating device moved through different distances during the act of drawing,
to correspond with, and effect the registering of the different prices of the quantities
of liquid drawn.
A practical embodiment of my invention is represented in the accompanying
drawings, in which :-
Fig. 1 is a view of the apparatus in side elevation.
Fig. 2 is a front view.
Fig. 3 is a top plan view.
Fig. 4 is an enlarged view of the parts, exclusive of the receptacle from which
the liquid is drawn, taken from the opposite side from Fig. 1.
Fig. 5 is a section through line, Fig. 4, looking toward the front.
Fig. 6 is a view through line y y of Fig. 5.
Fig. 7 is a view through line zz of Fig. 6.
Fig. 8 is a transverse vertical section, partly in elevation, and on an enlarged
scale, of the receptacle from which the liquid is drawn; and
Fig. 9 is a similar view of a modified form of receptacle and outletting device.
A represents a receptacle from which the different quantities of liquid are to be
drawn. An air inlet and outlet valve a is seated in a chamber a', in communication
with the top of the receptacle. When the valve is down, as in Fig. 8, air may
pass freely by it, but when floated to its seat a' by the rising of the liquid, it will
cut off the escape of the liquid by overflow.
I have shown the receptacle A enclosed within a casing B, the interior of which
may form a cooling chamber, and have shown a supply pipe C, leading from a
source of supply, not shown, through the interior of the casing B, and thence to a
three-way cock D, located at the juncture of pipes d and d', the former leading to
the receptacle A, and the latter to a spout d².
Liquid is admitted to the pipes d, from within the receptacle A, by an outletting
device controlled by the operator, as follows:
A rock shaft E, tubular at its inner end, as shown at e, Fig. 8, extends through
the end of the receptacle A, the tubular portion extending from without, to a point
within the receptacle, and at its inner end provided with a laterally extending
tubular arm e', open at its end, and in communication with the hollow portion e of
the shaft.
The shaft enters the receptacle at or near its bottom, and preferably off to one
side of the bottom, and, as the shaft is rocked, it will raise or lower the open end
of the arm e', so as to draw from within the receptacle A, a lesser or greater
amount of the liquid therein. The hollow portion è of the rocking shaft is at all
times in communication with the pipe d, leading to the receptacle, the communication
being preferably established by means of a chamber e³, at the front of the receptacle,
with which chamber the hollow portion e of the rock shaft and the pipe à both
communicate.
The shaft E has fixed on its front end a crank e, by means of which it is rocked
to raise and lower the mouth of the arm e', within the receptacle and the handle e³

page_text: of the crank is so connected with the crank proper, as to yield in the direction of
its length, and thereby release a point e, on its inner end, from shallow seats
numbered 1, 2, and 3 respectively, and formed in the outer face of the support B¹,
in front of the casing B. The indentations 3, 2, and 1, are so located as to hold
the outletting arm e in position to draw from the receptacle A, three pints, two
pints, and one pint respectively. It is of course understood that the number of
different quantities, and the particular dimensions of the measures, may be varied
at pleasure, to suit the different purposes to which the apparatus may be devoted.
In setting the outletting device to permit the outflow of the different quantities
of liquid, I provide for the different rotary movements of the registry operating
shaft under the impulse of the lever which operates the three-way cock to dispense
the liquid, as follows:
On the shaft E, there is a fixed a pinion F, which intermeshes with a vertically
sliding rack bar G. The rack bar G has a set of rack teeth f thereon, for inter-
meshing with the pinion F, and another set of rack teeth y for intermeshing with
a spur wheel or sector H, mounted, in the present instance, on the same axis as the
cock-operating lever I. The spur wheel or sector H is fixed to rotate with a
sleeve h, which extends within a hollow hub i on the lever I, and both the wheel
and sector H and the lever I are mounted loosely upon a registry operating
shaft K. The shaft K has fixed to rotate therewith, a ratchet wheel k, and
connection between the said shaft and the lever I is effected by means of a spring-
actuated dog L, seated in a suitable socket formed in the hub of the lever I. The
sleeve, fixed to rotate with the spur wheel or sector H, is adapted to extend
across the path of the dog L, and holds it out of engagement with the teeth on the
ratchet k. The sleeve h is, however, cut away a predetermined distance, as shown
ath, Fig. 7, so that when its cut-away portion comes opposite the dog L, the latter
will be allowed to extend through the opening into engagement with the. ratchet
teeth. The movement of the sleeve h is so timed with respect to the movements of
the crank e, that when the crank is in position with its handle seated in the
socket 3, the downward stroke of the operating lever I will rotate the shaft K a
distance of three teeth of the ratchet k.
When the crank e* is turned to bring the handle into engagement with the
indentation 2, the sleeve will have been thereby rotated so as to interpose itself
between the dog L and a portion of the ratchet teeth on the wheel k, and a full
stroke of the operating lever I will effect a movement of the shaft K only a distance
of two teeth. In the same manner, the swinging of the crank e* down into position,
so that its handle will engage indentation 1, will interpose the sleeve h between
the dog L and the ratchet teeth, so that it will have an opportunity of moving the
shaft K one tooth only during a complete downstroke of the lever I. Thus, it will
be seen, that the movements of the shaft K depend upon the quantities which the
outletting devices are set to draw.
A registering device of any well known or approved construction is represented
conventionally by K', Figure 2, and is supposed to be operated by the shaft K.
The operating lever I is connected with a crank arm d' on three-way cock D by
a link do, and the communication between the outletting port in the cock and the
pipe d, is such, that the opening for the dispensing of the liquid is effected just as
the lever I reaches the downward limit of its stroke, and after it has rotated the
shaft K to a point within less than one-half a ratchet tooth's distance of its complete
stroke. The purpose of this is to complete the registry of the amount to which the
crank e* is set before a drop can be drawn.
In order to prevent the operation of the lever I when the crank e* is set at any
point intermediate of the predetermined point, and in order to prevent the
manipulation of the crank e* after the operating lever I has been started on its
stroke, I provide the following interlocking mechanism :-
A sliding pin or bar M is seated in a socket in the support in front of the
casing B, and is provided with beveled ends m and m' for engaging respective seats
formed in the operating lever I in a disc e carried by the shaft E. The lever I is

page_text: provided with a single seat m³, and the disc e with a number of seats m³, one for
each of the indentations, 3, 2, and 1, at which the crank is to be set to draw
predetermined quantities from the receptacle. The pin or bar M is of such length,
that when it is seated either in a seat in the lever or in the disc, the other of the
parts in which it is not seated will be allowed to operate, but not otherwise.
The seat in the lever is so located as to correspond with a seat in the disc when
the operating lever is at the uppermost limit of its stroke. If, therefore, it be
desired to operate the crank e* to set the outletting devices, the operating lever I
must be at the uppermost limit of its stroke, so that the pin or bar M may enter
the seat therein, and permit the shaft E to rock. On the other hand, if it be desired
to operate the lever I, the same one of the seats in the disc e must be directly
opposite the seat in the lever, in order that the pin or bar may be set free from the
lever and permit it to rock.
In Figure 9, I have shewn an outletting device in which the hollow portion of
the rocking shaft extends up through the bottom of the receptacle, and into its
interior, to such a height as desired for drawing the least quantity at one time from
the receptacle. Such modified form of outletting devices I have shewn by E¹, and
provided it with ports N and n, located at different heights through its side, and out
of alignment, and have surrounded the interior portions of such shaft with a
casing o, forming a liquid-tight joint therewith, excepting along the narrow slit o
extending from the bottom of the casing up to the top of the port N.
In operation, when the shaft E' is rotated so as to bring both of its ports out of
alignment with slit o in the casing O, it will draw from the receptacle only down to
a level with the top of the shaft. When it is rotated so as to bring the port N to
register with slit o, it will draw from the receptacle down to a point on a level with
the bottom of the port N, and when it is turned to bring the port n to register with
slit o, it will draw from the receptacle down to the bottom of the port n.
The three-way cock D to which reference has heretofore been made, may be of
any well known or approved form, the ports within being so arranged that when the
operating lever I is at the uttermost limit of its stroke, there will be free
communication between the supply pipe and the interior of the receptacle through
the pipe, and when the operating lever I is at the lowermost limit of its stroke,
communication between the supply pipe and the interior of the receptacle will
be shut off, and open communication established between the pipe d and the
spout d
It is obvious that slight changes might be resorted to in the form and arrange-
ment of the several parts described, without departing from the spirit and scope of
my invention; hence I do not wish to limit myself strictly to the structure and
arrangement herein set forth.
