PROVISIONAL SPECIFICATION.
Improvements in or relating to Machines for Cutting Chaff and
other similar Substances.
I SAMUEL EDWARDS of Ladywell, Eccles, in the County of Lancaster, Agricultural
Engineer, do hereby declare the nature of this invention to be as follows:-
My invention relates to machines for cutting chaff and other similar substances
the object of which is to reduce the power required and add to the durability of
the above class of machines. To enable me to do this I purpose fitting roller
bearings to all the main spindles instead of the ordinary fixed metal bearings. In
order to do this I make the outer case of the bearings a greater diameter than
that of the spindle. The difference between the diameter of the outer case and
the diameter of the spindle represents the diameter of the rollers which form the
roller bearings. These rollers are bored out and kept equi-distant by means of
pins passing through them. These pins are journaled down at each end and
riveted into rings. These rings can be either in one part or made in semicircles
the latter preferred. To keep the rings in position endwise I put two semi-
circular plates at each side of the bearing one on the cap and the other on the bottom
bearing. These plates have an opening slightly larger than the diameter of the
spindle and form a receptacle for the lubricating oil, I do not confine myself to the
above particular form of roller bearing but to the use of roller bearings in the above
class of machines.

Improvements in or relating to Machines for Cutting Chaff and
other similar Substances.
I, SAMUEL EDWARDS of Ladywell, Eccles, in the County of Lancaster Agricultural
Engineer do hereby declare the nature of this invention and in what manner the same
has to be performed, to be particularly described and ascertained in and by the
following statement :-
The object of my invention is to enable such machines as chaff cutters and similar
machines for cutting substances, to be driven or worked with less power than hitherto,
and thereby to add to their durability, and to accomplish this object, I make all the
main shafts or spindles to revolve upon roller bearings in the following manner,
reference being had to the drawings which form part of this specification.

page_text: Fig. 1, is a side elevation of an ordinary chaff cutting machine, showing one of the
roller bearings of the fly wheel shaft.
Fig. 2, side elevation of the roller bearing on an enlarged scale.
Instead of and in substitution for a bearing fitted with solid brasses as used heretofore,
I construct the bearings A, B and C, preferably as follows: I bore out the body D,
and cap E, to a greater diameter than that of the shaft or spindle F, and I make a
number of rollers G, their diameter being such as to fill up the annular space between
the said shaft and the bearing, the number of the rollers will depend upon their
diameter and the size of the bearing.
They are bored out and are kept equidistant by means of short axles passed through
them and rivetted into rings H, on each side of the rollers, the rings being made
solid or in sections.
To secure the whole in position within the parts D and E, I use end plates I, and J,
which are screwed upon sides of the body D, and the cap E, and thus prevent any
lateral movement, they also retain the lubricant within the bearing, the revolving
rollers transmitting it to the shaft F.
This construction of roller bearing lends itself satisfactorily to this class of machine
and the work it has to perform, but I do not confine myself to this particular con-
struction, as it will be evident that they may require to be varied in construction to
suit different sizes and makes of such machines.
In the machine shown, K is the frame, L is the fly wheel carrying the cutters M,
and N is the top motion spindle.
Having now particularly described and ascertained the nature of my invention
and in what manner the same is to be performed, I declare that what I
claim, is:
1. In a machine for cutting chaff and other similar substances, supporting the main
shafts in roller bearings constructed as hereinbefore described and shown in Fig. 2 of
the drawings.
2. A machine for cutting chaff and the like having its main shaft or shafts carried
in roller bearings, substantially as herein before described and set forth.
