COMPLETE SPECIFICATION.
An Improved Raisin Seeding Machine.
I, CHARLES BRISTOW, of 42 Lambton Quay, in the City of Wellington, in the
Colony of New Zealand, Engineer, 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:-
The object of my invention is to obviate the necessity for the unpleasant and
wasteful practice of stoning or seeding raisins by hand, and to provide a machine
which will entirely remove the seeds from the raisins and deliver the said seeds in
a comparatively clean condition into a separate receptacle.
My invention is illustrated on the accompanying sheet of drawings on
which:-
Figure 1 is a front view of my machine.
Figure 2 is a side view of the same; and,
Figure 3 is a plan looking down on the same with the hopper and scraper
bar removed.
(a) is a standard clipped to the table (b) by the jaw (c) and screw (d) or in any
usual manner. This standard (a) carries a frame (e) in which revolve rollers (f)
and () in bearings (g). These rollers are revolved by hand by means of the
handle (1) through the medium of the toothed wheels (i) and (i).
The rollers () and (f) are set at such a distance apart and are of such a
diameter that the raisins can be squeezed between them without allowing the seeds
to pass, therefore the seeds remain above and are slided or pushed along in the
direction of the arrows (see Figure 3) by means of the spiral (2) attached to ove
or to both of the rollers, and deposited in the receptacle (k), whilst the raisins
drop through the rollers and are caught in any suitable place or receptacle (m);
the plate (n) preventing them reaching the seed receptacle (k). To more
thoroughly clean the raisin seeds from pulp, spring teeth or rubbers (0) (0¹)
and (o 2) are supported by a bar (p) and project down between the upper portion
of the rollers so as to check the progress of the seeds and rub them against the
spiral (2). (r) are scraper bars set so as to nearly touch the rollers (f) and (f¹)
in order to scrape any adhering matter into the receptacle (m). The raisins are
fed into the rollers from a hopper (q).
It will be evident that my invention admits of variations in detail such as the
method of driving by hand or power, also brushes of wire or other material may
be substituted for the spring teeth (o) (o') and (02), or a single wire screen or
brush might be placed at the end of the rollers for the purpose of cleaning the
seeds more effectually.
Having now 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. In a raisin seeding machine the rollers (f) and (f) (having a spiral ƒ2)
for the purpose of squeezing the seeds from the raisins, depositing the raisins in a
receptacle (m), and the seeds in a receptacle (k) substantially as set forth and
illustrated.
2. In a raisin seeding machine the rollers (f) and (f) having toothed wheels (i)
and and a handle (b) for revolving the same.

page_text: 3. In a raisin seeding machine the rollers (f) and (f¹) combined with spring
teeth such as (o) substantially as set forth and illustrated.
4. In a raisin seeding machine the frame (a) carrying rollers (/) and (f),
wheels (i) and (i) handle (h) hopper (9) and receptacle (k) substantially as set
forth and illustrated.
5. In a raisin seeding machine the frame (a) carrying rollers (f) and (f¹)
(one or both of which are fitted with spirals such as f2) driven by wheels ()
and () and handle (h), and having scrapers and any number of spring teeth or
brushes such as (o) substantially as set forth aud illustrated.
Dated this 30th day of January 1896.
