COMPLETE SPECIFICATION.
An Improved Machine for Measuring Flour, Grain, Seeds, Spices,.
and Pulverulent or Granular Materials Generally.
I, WILLIAM RICHARD CLARKE, trading as W. G. Clarke & Son, of the
Anchor Biscuit Works, Limehouse, London, E., Biscuit Manufacturer, Seed
Flour and Grain 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:-
My improvements are devised with a view to effect by the hereunder described:
means which I employ according to my invention, the expeditious and accurate
measuring in predetermined quantities of flour, grain seeds, spices and pulverulent
or granular materials generally.
And in order that my invention may the better be understood I have appended
the accompanying 2 sheets of drawings in which
Figure 1 Sheet 1 represents a plan view of my improved machine, Figure 2, a
front view of same,
Figure 3, Sheet 2 shows a sectional view of the divided drum hereinafter
referred to, and
Figures 4 & 5 are front and back face views of the finger and star wheels also.
hereinafter referred to.
Now in accordance with my invention, I mount my improved machine upon a
frame which consists of say three uprights or standards a, b, c, secured together.
by means of rods and bolts. Between the standards a, b, I secure a drum or
chamber d having an outlet covered by the hopper e, at its top and a shoot or
channel fat its bottom.
I also provide a second drum 9 divided into 4 equal parts as shown more
particularly Figure 3 and which is mounted upon the spindle h and revolved by
means of the mechanism hereinafter referred to, within the drum d.
The driving mechanisin above referred to employed in connection with my
invention and which is supported within the standards b, c, is as follows:-viz. :-
Mounted upon the spindle i which is secured to the standard c, by means of the
brackets j, is a worm or tangent screw m and the driving pulleys 11. Said worm in
gears into a worm wheel k mounted loosely upon the herein before referred to
spindle h. One half of the boss of the worm wheel k is projected and formed with
teeth or serrations which correspond with those formed upon the clutch n, which
latter is provided with a pin or projection n' and is secured to the shaft by means
of a key and keyway. Also mounted upon said shaft is what I term a finger
wheel o having formed on its edge a projection of the object of which is hereinafter
stated. I also form on one face of the finger wheel ó a channelled collar o*
around which is placed the washer o³ hereinafter more particularly referred to.
Secured to the standard b, and parallel with the shaft h, I provide another shaft
carrying a star wheelp having a collar p¹. A segment of the above referred to
washer o is cut away at its edge so as to allow the collar p¹ to fit therein.
A hand lever q is provided at the face of the machine, and secured to the
standard a. Said lever has a slot cut therein into which is inserted, the pin q¹
projecting from the connecting rod r to which latter is attached the clutch lever
secured to the standard by the bracket r².
:
The working of my improved machine is as follows, viz. Taking for instance
the divided drum g is of such dimensions as to be capable of holding one quarter of

page_text: a bushel in each divided compartment. The sack is placed under the mouth of the
shoot and suspended by means of the hooks s. The material is then allowed to
enter the hopper e whence it passes down into one of the divided compartments in
the drum 9. The driving mechanism is now put into gear by means of the lever
and connecting rod r acting upon the clutch lever thus moving the clutch along
the spindle h until it is in gear with the worm wheel k. The act of putting the
driving mechanism into gear withdraws the pin or projection n¹ formed on the
clutch n from the slot or hole p² formed in the collar of the star wheel pl. Motion
is now imparted to the divided drum g which on completing one revolution, the
projection of formed on the finger wheel o takes into one of the openings p³ of the
star wheel p thus giving the latter a quarter turn.
During the revolution of the druin the pin or projection n' takes a bearing
against and revolves round the face of the washer o³ placed upon the collar o² of
the finger wheel o and part of the collar p¹ formed on the star wheel p. Upon the
finish of the fourth revolution of the drum the above referred to pin or projection n¹
meets and is drawn by the action of the spring, into the hole på formed in the collar pl
of the star wheel p thus disengaging the clutch n and worm wheel k which latter
now runs loosely upon the spindle h. The sack would now contain 4 bushel, struck
measurement, of the material or substance, and is taken away and a fresh one
supplied, when the machine is again put into motion and the same operation as
above described takes place. I may if deemed desirable employ any suitable
sonorous annunciator to give warning to the attendants when the machine is thrown
out of gear.
Having new particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
(1.) The improved machine for measuring flour, grain, seeds, spices and
pulverulent or granular materials generally, substantially as herein set forth and
shown in the accompanying sheets of drawings.
(2.) In machines such as those described in the preceding claim, the employment
of a divided drum g revolving upon the spindle h substantially as and for the purposes
herein described and shown in the accompanying sheets of drawings.
(3.) In machines such as those referred to in the preceding claim the means
employed for causing the driving mechanism to be thrown in and out of gear,
arranged, constructed and operated in the manner herein set forth and shown in
the accompanying sheets of drawings.
Dated this 24th day of December 1895.
