PROVISIONAL SPECIFICATION.
An Improved Apparatus for Cutting Long Shavings into Chippings or
Adzings.
I, THOMAS NIELD ROBINSON, of Thomas Robinson and Son Limited, of Rail-
way Works, Rochdale, in the County of Lancaster, Machine Maker, do hereby
declare the nature of this invention to be as follows:-
My invention relates to an improved apparatus for cutting long shavings into
chippings or adzings and my object is to provide apparatus for cutting the long
shavings produced by the fixed knife or knives of a floor board planing machine
or other wood working machine into fine chippings so that they can be easily
removed with the other refuse and burned in a furnace.
In carrying my invention into effect I arrange a hopper below the stationary
knife or knives and I mount a pair of feed rollers at the bottom of the hopper
and drive these feed rollers by any convenient arrangement of driving gear.
As the shavings are formed they fall into the hopper and are drawn through
the rotating feed rollers below which are mounted a plain fixed cutter and a
rotating cutter with preferably helical blades. The shavings as they issue
from the nip of the feed rollers are struck by the rotating cutter against the
stationary cutter blade and are so cut and broken up into small fragments or
chippings.
Dated this 30th day of June 1899.

I, THOMAS NIELD. ROBINSON, of Thomas Robinson and Son Limited, of Rail-
way Works, Rochdale, in the County of Lancaster, Machine Maker, do hereby
declare the nature of this invention and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:-
My invention relates to an improved apparatus for cutting long shavings into
chippings or adzings and my object is to provide apparatus for cutting the long
shavings produced by the fixed knife or knives of a floor board planing machine
or other wood working machine into fine chippings so that they can be easily

page_text: In the accompanying sheet of drawings-
Figure 1 is an end elevation, Figure 2 a side elevation and Figure 3 a plan of
my improved apparatus for cutting long shavings into chippings or adzings
and Figures 4 and 5 are detail views of the rotating cutter.
In carrying my invention into effect I arrange a hopper (not shown) below
the stationary knife or knives of the floor board planing machine, and I mount
a pair of feed rollers a b at the bottom of the hopper and drive these feed
rollers by any convenient arrangement of driving gear. The feed roller a is
carried by a pair of backets c bolted to a stationary frame d, and the feed
roller is carried by a pair of arms e pivoted at f to the frame d. The two
feed rollers a and b are held normally in contact by means of a pair of coiled
springs which are adjustable by screws h and nuts i or any equivalent device.
As the shavings are formed in the wood working machine they fall into the
hopper, and are drawn through the rotating feed rollers a, b below which are
mounted a plain fixed cutter and a rotating cutter m with preferably helical
blades as shown in the detail views Figs. 4 and 5. This rotating cutter m is
journalled in bearings in the frame d and is driven by a belt on a pulley o or
by other suitable driving gear. The bearings of the rotating cutter m are
adjustable relatively to the fixed cutter by means of screws and lock nuts n.
The shavings as they issue from the nip of the rotating feed rollers a b are
struck by the rotating cutter m, against the stationary cutter blade k and are so
cut and broken up into small fragments or chippings.
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: —
The improved apparatus for cutting long shavings into chippings or adzings
said apparatus consisting essentially of a fixed cutter blade and a rotating cutter
mounted below a pair of rotating feed rollers all substantially as and for the
purposes herein described with reference to the accompanying drawings.
