Improvements in Apparatus for Delivering Measured Quantities.
1, HENRY CHARLES SCHOLES of Clematis Villa Stoneygate Road Knighton
in the County of Leicester Gentleman do hereby declare the nature of this inven-
tion to be as follows:-
This invention relates to improvements in apparatus for delivering measured
quantities, for automatically receiving, measuring and discharging liquids, or gas;
applicable for all liquids and gases with or without any ordinary registering
appliances affixed thereto.
The object of this my invention is to provide an automatic measurer for liquids,
grases, vapour, granular substances or powders by the means of valve taps explained
in my application for Patent No. 12197 A.D. 1890, which may be of desired
any
shape or size and made of metal, or part metal and part glass, they are internally
screwed at their upper ends to receive the externally screwed end of the supply
pipe, or may have an angular screwed end attached to the tap to connect to the
vessel, or source of supply, the size of the body or may be bulb is made to a certain
size that only a predetermined quantity of the liquor can be obtained at one time.
At both ends of the body of the tap are flanges to receive slide valves, the upper
one being made proportionately longer than the lower one, to shut off the supply
before the delivery of the contents of the tap is discharged from the lower end,
these slide valves are hinged to straight or curved levers centrally pivoted to an
arm extending from the body of the tap or to a rod on a cam wheel attached to an
angular faced circular disc working on a central arm, and turned from a knob on
the outside, the act of turning withdrawing the lower valve and pushing forward
the other for delivering the contents of the tap.
°
Or the said angular faced disc may carry instead of the rod, a cog wheel, and I fix
one on each end of the lever bars also, when by turning the knob outside as before
stated the tap is opened or closed, suitable packing is provided in the parts of the
parts most desirable. Or the slide valves may be C shaped a portion of the
periphery of which carry rack teeth, which fit in with cogs on a flanged pulley
with central bar support and carrying a weighted chain, the outer end of which is
secured to a small rod with knob, under the weight attached to the chain is a small
platform to avoid recoil of the weight. Or outer and inner bulbs may be
employed, the internal one having holes, one to connect supply and the other for
delivering the contents, and operated by the same means as above described, the
end for delivery having a pipe attached. Or the levers connected to the arm may
operate lifting plates, or cup and ball valves on seating in the body of the tap.
Each tap can be locked up by having eyes inserted under the bottom flange of the
tap and pull bar, and a padlock secured to both. In the case of powders, grain or
thic like being measured the levers or sliding valves are made with sharp edges
and the interior guides in body of tap and in pipes from the supply are longer and
funnel shaped than in the case of liquids.

Improvements in Apparatus for Delivering Measured Quantities.
1, HENRY CHARLES SCHOLES of Clematis Villa Stoneygate Road Knighton
in the County of Leicester Gentleman, do hereby declare the nature of this inven-
tion 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 improvements in apparatus for delivering measured
quantities for automatically receiving, measuring and discharging liquids or gas;
applicable for all liquids or gases with or without any ordinary registering
appliances affixed thereto.
The object of this my invention is to provide an automatic measurer for liquids,.
gases, vapour, granular substances or powders by the means of valve taps explained
in my application for Patent No. 12197 A.D. 1890, and illustrated in the accom-
panying drawings to which I will now refer.
Figure 1 represents in section one arrangement of measuring tap J, employed
having the packed flanges ¹, in which fit the slide valves, hinged to the lever,
centrally pivoted to the arm on the body of the tap. This tap is adapted to hold
granular substances and is operated by the lever arm to shut off the supply before
the delivery of the measured quantity, in the measuring chamber, at the end of
the lower valve is attached the handle or its equivalent L, which is brought back
to repose by the spring j
Figure 2 represents a side view partly in section of valve tap J, operated by
crank lever, to which is attached the rod and handle L, the body of the tap is
the measuring chamber which may be of any suitable shape, and attached to the
supply valve box, j, and delivery valve box made as shown in section the conical
plug valve leaving its seating to release tlic liquid in the measuring chamber, after
the outer end or tail of the valves have been pressed inwards the spring ja brings
them again into the seating for closing supply, the crank lever being brought to
repose by the spring, the air valve is provided consisting of push rod operated
by push lever j.
Figure 3 is a side view also partly in section of an ordinary plug slide tap J,
operated by the crank levers, to both of which is attached the measuring
chamber, in addition I may employ the air valve ", fitted in the shoulder to
force delivery, the crank lever bar, being attached to or may form part of the
pull or push bar L.
Figure 34 is a sectional view of the air valve", which consists of a three sided
spindle, carrying a cone 13, in a ground seating 14, and nut jo secured in the body
of any of the measuring taps, J.
Figure 4 is a sectional view of a cup and ball tap J, operated by the spring
pressed piston rods, by pressure of the crank lever, connected to the pull or
push lever bar L, the loose balls, fit in the packing cups 7, and 18, and are
released both for closing supply or delivery by pressure of the springs j³, after
crank lever has been withdrawn the spring, brings it back to repose.
Figure 5 is a sectional view of a cup and ball valve tap J, which is operated in
a similar manner to the preceding figure, but adapted to be made in glass.
Figure 6 is a view partly in section of another slide valve tap J, the piston
rods, being operated by the lug on the bar L, which comes in contact with the
outer ends of the piston rods, the valves of which close on their seatings by aid of
the springs jº.
Figure 7 is a sectional view of a slide lever tap J, having the wedge or spear
shaped valves on end of the piston rods, the valve seatings may have any suitable
packing therein j¹, and close on their seatings by pressure of the springs, the
lever bar j³, being connected to the push or pull bar L, which is normally held by
the spring, the air valve j", consisting of a ball in wire gauze cage in the
shoulder of the measuring chamber je.

page_text: Figure 8 is a sectional view of a measuring tap J, provided with turn axle
bar L, jointed at it, to connect the supply valve, to the axle carrying the delivery
valve both have inlet holes jx, and pipe, and exit holes j×1, and pipe for delivery,
upon turning the axle bar L, half round to the right or left as will be notified
thereon the liquid passes into the delivery chamber and pipe.
And Figure 9 is another sectional view of the measuring tap J, the conc valves
both for supply to measuring chamber, and delivery, being closed on their
seatings by the springs, and released by the lugs j*, on the rod jxx, which is square
at top and is held by the spring j, to close delivery, the said rod is acted upon by
the finger, attached to the bracket upon which is the lever connected at its free
end to the pull or push bar L.
The said taps may be of any desired shape and size and made of metal, or part
metal and part glass, they are internally screwed at their upper ends to receive the
externally screwed end of any ordinary supply pipe or may have an angular screwed
end attached to the tap to connect to the vessel or source of supply, the size of the
body, which may be bulb, is made to a certain size that only a predetermined
quantity of the liquor can be obtained at one time.
Packing of any kind to the parts necessary is used and may consist of india
rubber rings, leather, asbestos or the like ordinarily used for such purpose.
Each tap may be locked up by having eyes made under the bottom flange and
pull bar and a padlock secured to both "not shown." And in the case of measuring
and delivering a predetermined quantity of powders, grain or the like, the levers
or sliding valves may have sharp edges and the interior guides in body of tap and
in the supply and delivery chambers and pipes may be funnel shaped "Figure 1
to facilitate delivery.
"
For delivering measured quantities of vapour or gases, the flanges are made air
tight, and provision is made to ensure the said taps from bursting.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is 11
1. In measuring taps of the character herein described the arrangement of valve
chambers in combination with the measuring chamber, constructed and arranged as
shown and specified.
2. In a measuring tap the employment of an air valve such as ", Figures 3, 34,
5, and 7 or as shown in Figures 2 and 8, in measuring and discharging liquids, to
facilitate discharge.
3. Improvements in self measuring taps arranged in the manner and for the
purpose substantially as herein described and set forth.
