Improvements in Faucets for Measuring Fluids.
I, GEORGE W. MILLER, a Citizen of the United States of America, residing at
Lexington, in the County of Dawson, and State of Nebraska, U.S.A., Merchant,
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:-
This invention relates to measuring-faucets which are adapted to be driven or
screwed into a barrel or tank to draw any kind of fluid therefrom, and its object is
to provide means whereby large quantities of fluid-such, for example, as kerosene-
oil-may be rapidly drawn through the faucet and measured thereby to any
prearranged amount required and the delivery be stopped automatically when the
required amount is discharged, whether the operator be present or not.
To this end my invention consists in the construction and combination of parts
forming a measuring-faucet hereinafter described and claimed, reference being had
to the accompanying drawings, in which―
Figure I is a front end view of a faucet according to my invention, a portion
being broken away to expose to view parts beneath.
of Fig. II.
Fig. I is a central longitudinal vertical section of the same.
Fig. III is a transverse vertical section at the line
Fig. IV is an under side view of the telescoping tube.
No. 5 represents the body of the faucet, made in a tapering form and adapted to
be either screwed or driven into a barrel or tank. This body portion is provided
with a valve-seat 6, into which a valve 7 is fitted. A valve-rod 8 passes out
through a stuffing-box 9, and is secured at 10 to a tube 11, which is fitted to
telescope within a tube 12, which is rigidly secured to or made a part of the
body 5.
13 is a spring acting between the telescoping tube 11 and the head of the faucet
to push the said tube outward and to draw the valve 7 into its scat 6 to hold it
closed.
14 is a trigger pivoted to the outer tube 12 at 15 and provided with a catch 17,
adapted to engage a corresponding catch on the telescoping tube 11 when the latter
is pushed in, as shown in Fig. II, and adapted to disengage the said telescoping
tube and permit it to be sprung outward to draw the valve to its seat when its
opposite end 18 is moved to one side.
16 is a pin or stud projecting from the tube 11 through a slot in the outer tube to
engage a slot 19 in the trigger 14.
20 is a cylinder attached a little to one side of the center of its own top to the
delivery end 21 of the faucet, and having an opposite outlet 22, to which an internal
longitudinal groove 23 leads.
24 represents a series of buckets fixed upon a shaft 25, which is mounted to

page_text: revolve in bearings in the cylinder 20 and fitted to bear neatly within the cylinder
to form a revolving contact therewith sufficiently close to prevent leakage of fluid.
The spaces between these buckets may be such as to contain any unit of measure―
such, for example, as one gallon.
26 is a spur-wheel fixed upon the shaft 25 to revolve therewith.
27 is a bracket fixed to the outer end of the cylinder 20 as an outer bearing for
the shaft 25 and shaped with a concentric sleeve. 28 to serve as a bearing for a
dial 29. This dial has an internally-toothed flange, 30, which is connected, with the
pinion 26 by means of an intermediate wheel 31, which is journaled upon a stud 32,
fixed to the end of the cylinder.
33 is a hand or pointer having a slot midway to slide freely upon the shaft 25,
and kept thereon by a screw nut or head 37, and further provided with a stud 34,
projecting inward to engage, a volute thread 35 on the face of a disk 36 which is
rigidly fixed to the sleeve 28, whereby the hand 33 will be drawn toward the center
when turned backward; and will be radially pushed away from the center while
revolving forward. The dial 29 is formed as a crown-wheel, its teeth 38 projecting
outward, and numbered with a certain fixed relation to the measuring-buckets 24.
*The hand 33 is adapted to engage any of the teeth 38, and it normally stands
sprung in between them and must be raised out by a person's fingers and revolved
around to be set at any point desired as an index to the amount desired to be drawn
through the faucet. The projecting end of this hand revolves in a path to engage
and trip the trigger 14 at the moment when the amount of fluid indicated by the
location of the hand on the dial has been delivered.
•
The drum 20 may be adapted to contain any number of buckets 24, and if there
are five buckets, as here shown, cach capable of holding one gallon, every revolution
of the shaft 25 will deliver five gallons, and the ratio between the pinion-wheel 26
and the inner circumference of the wheel or flange 30 upon the dial 29 may be
arranged for the dial to register any desired number of revolutions or the. parts of
a revolution.
The operation is as follows: Set the hand 33 at that notch upon the dial.which
indicates the number of gallons desired. Then push in the tube 11 until it is caught
by the hand 14, and the fluid will begin to run, filling the buckets and turning them
forward, also carrying the dial and hand, and when the hand reaches the trigger 14
it will trip it and permit the tube 11 to be thrown out by the spring 13, thus closing
the valve 7 and stopping the delivery. When the tube 11 is thus sprung out, the
stud 16 attached to it, sliding in the slot 19 of the trigger 14, returns the trigger
to its normal position, ready to engage the catch 17 whenever the tube 11 is again
pushed in to open the valve. Should it be desired to draw at one time more than
is indicated by one revolution of the hand upon the dial, the hand may be raised
out of engagement with the teeth 38 and turned backward as many revolutions and
parts of a revolution as will indicate the amount desired to be drawn. The hand
in being turned backward is drawn inward at its point by the stud 34 travelling in
the volute 35. After it has been drawn inward one revolution its point will pass
under and not engage the trigger. 14, and for a greater number of revolutions.it is
drawn still farther in, and it will not project enough to engage the said trigger until
by delivering the amount of fluid required it is revolved forward and projects far
enough to engage the trigger. This will be at the point indicating the..amount
delivered after the faucet has been once filled.
The dotted lines 39 show the position of the valve closed and the dotted lines 40
Ishow the position of the telescoping tube 11 at the same time; the said tube serving
as a handle for the valve. This faucet having been set to deliver the number of
gallons required; the operator may go about other business and leave it to auto-
matically stop itself at the proper moment, thus saving time. There is sufficient
resistance to the buckets revolving to insure their being filled, and after, once having
been started a bucket full-is always at the delivery ready to be discharged the
grooves 23 aiding it to deliver rapidly.
