Improvements in Apparatus for the Delivery of Sugar and other
Substances in Measured Quantities.
I, GEORGE WILLIAM HADDOX, of 13, North Main Street, Winchester, Virginia,
United States of America, Merchant, 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 a measuring cabinet of the kind that is adapted for
use in retailing sugar and other commodities that are generally sold in quan-
tities of definite, or approximately definite weight or by the usual measures of
capacity. It is an object of the invention to provide an improved double acting
slide mechanism for controlling the charging and emptying of any one of a series
of measuring receptacles that differ in capacity according to the quantity of
material desired and to so construct the said mechanism that each fully charged
receptacle may be wholly emptied and made ready for further use before any
more material is admitted.
My invention consists in features of construction and novel combinations
of parts in a measuring cabinet as hereinafter more particularly described.
In the annexed drawings illustrating the invention
Figure 1 is a vertical section of my improved measuring cabinet from front
to rear.
Figure 2 is a part sectional front elevation of the cabinet.
Figure 3 is a horizontal section of the same above the guides for the upper
slides.
Figure 4 is an enlarged vertical section through one of the measuring recep-
tacles and its adjusting plate.
Figure 5 is a perspective of one of the measuring receptacles partly broken
away.
Figure 6 is a perspective of the slide mechanism.
The cabinet 1 may have any desired dimensions. A convenient size to adapt
it to the handling of, say, one barrel of sugar at a time would be about five feet
high, four feet wide and about twenty inches to two feet through from front to
rear. The upper part of the cabinet is occupied by a hopper 2 having a double
inclined bottom. In the bottom of the hopper there is provided a series of oblong
openings 3 through each of which the hopper is adapted to communicate with
one of a series of measuring receptacles 4 mounted beneath the hopper. These
openings 3 are formed through two parallel guide bars that are extended
lengthwise of the cabinet and one above the other, with a slight space between,
as shown in Figures 1 and 2.
It is preferable to make each measuring receptacle 4 with approximately the
outlines of a double triangle, in vertical cross-section, or double inclined at top
and bottom as shown in Figures 1 and 5. This form of measuring receptacle
permits filling to its exact capacity with such material as sugar, for instance,
and also facilitates a rapid and complete discharge of the quantity measured.
Each measuring receptacle has its discharge through an oblong opening 6

page_text: formed in two parallel guide bars 7 that are extended lengthwise of the cabinet,
one above the other and with a space between as in the case of the upper guide
bars 5, before mentioned.
For the purpose of controlling the entrance of material into the measuring
receptacles 4, through the upper inlet openings 3, and its discharge through the
lower outlet openings 6, there are provided a series of upper slides S and lower
slides 9 each of which is provided with a slot or opening as 10 and 11, Figures 1
and 6, to register at the proper time with the openings through the guide bars 5
and between which the said slides are arranged to operate. The upper slide
or cut off 8 and lower slide or cut off 9 are connected in such manner as to be
actuated in unison and in such a way that passage through one slide is fully
closed before a passage through the other slide is opened. This prevents any
continuous stream of material through the measuring receptacle, direct from its
inlet to its outlet, and permits an accurate measurement of the material to be
delivered.
As shown in Figure 6, the ends of the slides 8 and 9 are centrally slotted and
provided with eyes 12 for reception of pivots 13 the central portions of which
engage the ends of levers 14 that connect the slides 8 and 9 at both ends. Each
of these levers 14 is fulcrumed in a yoke 15 on a bar 16 that is extended length-
wise of the cabinet. There are two longitudinally extended bars 16, as shown
in Figures 1 and 3, one bar being at each side of the series of measuring recep-
tacles and secured thereto. The ends of these bars 16 are preferably made with
right angled extensions through which the bars are bolted to the ends of the
cabinet, as shown in Figures 2 and 3. It will be seen that by means of the upper
and lower guide bars 5 and 7 and the side bars 16 the series of measuring recep-
tacles 4 will be firmly supported in the required position within the cabinet.
Each lower slide 9 has connected with its front end an operating lever 17
that is extended through a guide opening 18 in the front of the cabinet. The
inner end of the lever 17 may be bifurcated, as shown in Figures 3 and 6, and
attached to the pivot 13 at each side of the lever 14 where it connects with said
pivot. At its outer end, each lever 17 is provided with a knob 19 or other handle.
Below and around the exit opening of each measuring receptacle 4, there is a
spout 20 having the form of a hollow truncated cone for guiding or directing
discharge of the measured material into one of a series of discharge hoppers 21
each of which is constructed with an inclined bottom having a tubular discharge
spout 22 in its central portion.
Although the drawings show only three measuring receptacles, of differing
dimensions, it will be obvious that the cabinet may be fitted with any number
of receptacles desired and these may each have any capacity suited to varying
quantities of material as usually sold. Thus the measuring receptacles 4 may
be graded for, say, one, two, three, four, five and ten pounds, or other quantities,
by measure or approximate weight. By operating the proper slide mechanism,
the required quantity of material is at once obtained and may be received in á
paper bag placed below and around the spout 22, or in any other receptacle as
desired. It will be observed, by reference to Figure 1, that on pulling out any
hand lever 17 to bring the opening 11 of the lower slide 19 into register with the
discharge opening of the measuring receptacle, the opening 10 of the upper slide
will be moved away from the inlet passage to said receptacle and the said inlet 3
will become completely closed before the outlet 6 is opened; also on pushing
the hand lever 17 inward, the outlet 6 is closed before the inlet 3 opens. Thus
there can be no stream of material flowing through the measuring receptacle
and the quantity of material required can be obtained accurately by operating
the slide mechanism of the proper receptacle. The arrangement of the levers 14
at both ends of the upper slides 8 and lower slides 9 provides for a pull" on
each slide in the required direction of movement, so that there is no liability of
causing the slide to "buckle," in either direction of movement. The slides are
preferably made of metal and are arranged to operate between and in close con-
tact with the guide bars 5 and 7 which may be also made of metal, or of wood

page_text: movable simultaneously in opposite directions to close the opening at either end
of the measuring receptacle before the other is opened, substantially as described.
3. In a measuring cabinet, the combination of a hopper, a series of measuring
receptacles located below said hopper in communication therewith and differing in
capacity, a discharge hopper below said receptacles, slides at top and bottom of
the measuring receptacles, centrally fulcrumed levers connecting the said slides
at both ends and adapted to control the inlets and outlets of said receptacles,
guides for said slides, and operating levers connected with the lower slides,
substantially as described.
