Improvements in Apparatus for Delivering and Registering Measured
Quantities of Granular or like Materials.
I, CHARLES RAGGETT, of 23, Rood Lane, in the City of London, do hereby declare
the nature of this invention to be as follows:-
According to this invention a hopper has at its lower end a measuring neck or
vessel closed at the top and bottom by slides which can be moved simultaneously
in the same direction. Each slide has in it a hole the two holes not being vertically
above each other. When the hole in the upper slide is below the mouth of the
hopper the measuring vessel fills and when the slides are moved the mouth of the
hopper is first closed by the upper slide and then the hole in the lower slide comes
beneath the measuring vessel which discharges its contents.
The slides are carried by a lever handle acted on by a spring in such manner
that the measuring vessel is normally open to the hopper. Fixed to the lever or
one of the slides is a bent arm entering the hopper at the upper part and passing
downwards through the granular material almost to the mouth. This arm acts
on a stirrer and prevents its choking.
Or the measure may be a slide closing the bottom of the hopper and working
on a base plate in which is a delivery aperture.
In order to record the number of measures withdrawn from the hopper the
handle has fixed to it a finger or blade which each time it is moved pushes the
lowest token or counter of a pile into a receptacle.

I, CHARLES RAGGETT, of 23, Rood Lane, in the City of London, 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:-
According to this invention a hopper has at its lower end a measuring neck or
vessel closed at the top and bottom by slides which can be moved simultaneously
in the same direction. Each slide has in it a hole the two holes not being vertically
above each other. When the hole in the upper slide is below the mouth of the
hopper the measuring vessel fills and when the slides are moved the mouth of the

beneath the measuring vessel which discharges its contents.
The slides are carried by a lever handle acted on by a spring in such manner
that the measuring vessel is normally open to the hopper. Fixed to the lever or
one of the slides is a bent arm entering the hopper at the upper part and passing
downwards through the granular material almost to the mouth. This arm acts
on a stirrer and prevents choking.
Or the measure may be a slide closing the bottom of the hopper and working
on a base plate in which is a delivery aperture.
In order to record the number of measures withdrawn from the hopper the
handle has fixed to it a finger or blade which each time it is moved pushes the
lowest token or counter of a pile into a receptacle.
The drawings annexed to the specification show an apparatus made in accordance
with this invention.
Figure 1 is a plan the top plate being removed, Figure 2 is a vertical section
on the line 2, 2, Figure 3 and Figure 3 is a horizontal section on the line 3, 3,
Figure 2. Figure 4 is a local vertical section through the measuring vessel.
a is the outer casing of the apparatus and b b are the sides of hopper containing
the material to be delivered. c is the measuring vessel fixed to the outer casing
by the rod cat c, c. d and e are two slides connected together by the piece f
and having holes and e¹ in them. The slides are operated by a handle g outside
the apparatus and are normally held with the hole of the upper plate coinciding
with the top of the measuring vessel c by a spring h. The bottom of the measur-
ing vessel is in connection with the delivery shoot i leading outside the casing of the
apparatus.
Attached to the slides is a bent rod & having prongs kl, as the slides turn motion
is given to the rod which revolves in the bearing and the prongs stir the material
in the hopper. A tube m contains tokens which are supported by the end of the
tube in which there is a slot m³. On the slide d is a pin d which as the slide is
turned engages with the lowest token in the tube m and when the handle is released
pushes it through the aperture m² (Figures 2 and 4) at the bottom of the tube into
a shoot n. The slides are encased between two plates o.
When the apparatus is in the position shown in the drawings the measuring
vessel is open to the hopper, on the handle being operated the top of this vessel
is closed by the upper plate and the hole in the lower plate is moved under the
bottom of the measuring vessel and the material in it is discharged into the
delivery shoot on the handle being released the slides return to their former position
by means of the spring h.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I declare that what
I claim is
1. The combination of a hopper, a measure beneath it and two slides fixed
together one above and the other below the measure.
2. Apparatus for delivering measured quantities of granular or like materials
substantially as described and shown in the drawings.
Dated this 28th day of January 1898.
