PROVISIONAL SPECIFICATION.
Improvements in Machines for Breaking, Grinding, or Crushing
Hard Substances.
I JAMES GADSBY RICHMOND of the firm of Richmond and Chandler of Southall
Street Manchester in the County of Lancaster Agricultural Implement Makers do
hereby declare the nature of this Invention to be as follows:-
My invention relates to improvements in machines for breaking grinding or crushing
miscellaneous hard substances such as oil cake for cattle, dog biscuits, oyster shells, etc.,
said improvements consisting mainly in a novel construction of the star rollers
employed in such machines and also in certain other arrangements hereinafter
described.
In constructing my improved star rollers I propose to make each roller of a number
of dises with spikes or teeth on their peripheries of different diameters and I prefer to
have two small dises and then one large disc and so on so that when the rollers are set
in their working positions one of the larger discs or discs of long teeth on one roller
comes between or opposite each pair of small discs or discs of short teeth on the other
roller by which arrangement the different speeds of the points of the teeth on the
opposite discs give a better breaking or crushing action to the machine. I mount one
star roller in a movable frame as now customary the frame with the roller being moved
to and from the other roller as required by the usual eccentric cam or equivalent a
catch or other means being employed to lock the roller when in the desired position.
The remaining features of my Invention consist first in the application of a scraper
formed with notches to correspond with the teeth of the movable star roller and
mounted on the movable frame near and parallel to the said roller this scraper is for
the purpose of cleaning the star roller by removing the large particles which adhere
to the teeth or spikes and as the scraper moves with the roller as the latter is closer to
or farther from the fixed roller it always retains its proper position close to the
movable roller; and secondly in making one side of the hopper inovable and in so
.connecting it with or operating it from the movable frame that when the latter is moved
to bring the two rollers nearer together or farther apart this side of the hopper will
also be moved toward or from the other as the case may be thereby adjusting the
mouth of the hopper relatively to the distance apart at which the two star rollers
are set for working.

Improvements in Machines for Breaking, Grinding, or Crushing
Hard Substances.
I, JAMES GADSBY RIOHMOND, of the firm of Richmond and Chandler, of Southall
Street, Manchester, in the County of Lancaster, Agricultural Implement Makers 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 :-

page_text: In constructing my improved star rollers I propose to make each roller of a number
of discs with spikes or teeth on their, peripheries of different diameters and I prefer
to have two small discs and then one large disc and so on so that when the rollers
are set in their working positions one of the larger discs or discs of long teeth on
one roller comes between or opposite each pair of small discs or discs of short teeth
on the other roller by which arrangement the different speeds of the points of the
teeth on the opposite discs give a better breaking or crushing action to the
machine. I mount one star roller in a movable frame as now customary the frame.
with the roller being moved to and from the other roller as required by the usual
eccentric cam or equivalent a catch or other means being employed to lock the roller
when in the desired position.
The remaining features of my invention consist first, in the application of a scraper
formed with notches to correspond with the teeth of the movable star roller and
mounted on the movable frame near and parallel to the said roller this scraper is for
the purpose of cleaning the star roller by removing the large particles which adhere
to the teeth or spikes and as the scraper moves with the roller as the latter is set closer
to or farther from the fixed roller it always retains its proper position close to the
movable roller and secondly, in making one side of the hopper movable and in so
connecting it with or operating it from the movable frame that when the latter is
moved to bring the two rollers nearer together or farther apart this side of the hopper will
also be moved toward or from the other as the case may be thereby adjusting the
mouth of the hopper relatively to the distance apart at which the two star rollers
are set for working.
And in order that my invention may be fully understood and readily carried into
effect will describe the accompanying Sheet of Drawings reference being had to
the figures and letters marked thereon.
Figure 1 is a side sectional elevation and Figure 2 a sectional plan of my improved
machine for breaking grinding or crushing hard substances.
In these views. a designates the main frame or body of the machine; b the star
roller which is mounted in fixed bearings and c the star roller carried in the movable
frame d which is operated as usual by the eccentric or came and handle e' to set the star
roller c nearer to or farther from the star roller b. When adjusted to the desired position
the framed with the roller cis locked by dropping the pivoted catch f into one of the
notches. Each star wheel or c is built up of two series of spiked discs one series
having longer teeth than the others and two of the discs with shorter teeth being
preferably placed on the roller axis between each pair of the discs with longer teeth so
that when the rollers bc are in the positions shown in the Drawings each longer tooth
on the one roller divides a pair of the shorter teeth on the opposite roller. The ends
of the portion d² of the frame d which portion d² forms the movable side of the
hopper are supported and guided in slots a¹ in the frame a and another portion d³, of
the movable frame d is notched to form the scraper for the movable star roller c.
The
other or fixed side of the hopper is formed by the piece n¹ and the scraper for
the star roller b is formed by the notched piece n both of which are preferably
cast with the piece n.
The star rollers b and c are driven as usual from the shaft g (on
handle g¹) by means of the pinions of which the pinion
drives a toothed wheel j fixed on the axis of the star roller 6
gears into and drives an internally toothed wheel k fixed on the
roller c.
which is fixed a
gears into and
and the pinion i
axis of the star
い
Having now particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
:-
1. In machines for breaking grinding or crushing hard substances constructing
each star roller of a number of discs having teeth of different lengths.substantially as
and for the purposes herein set forth.
2.-Combining the scraper for the movable star roller and one side of the hopper

page_text: with the movable frame which supports said roller substantially as and for the purposes
herein set forth.
3. The constructions and arrangements of parts which severally and in combination
embody my improvements in machines for breaking grinding or crushing hard
substances substantially as and for the purposes herein described with reference to the
Drawings annexed.
