similar Material for Plain or Fancy Box Making or other
Purposes.
I NATHANIEL BOTT CHADWICK of 3 St. Ann's Place St. Ann's Road Stamford Hill
in the County of Middlesex Engineer do hereby declare the nature of this invention to
be as follows:-
I propose to use a revolving Emery wheel so shaped as to grind out any shape of
groove required.
The method of using the Emery wheel is to revolve the same quickly on a spindle
which spindle is fixed over an iron table and is made to rise or fall to suit the
thickness of material operated on and the wear of the Emery wheel.
The method of using this is for the operator to firmly grasp the sheet of Cardboard
or other material to be operated on and guide it on the table underneath the Emery
wheel to make the groove in any desired direction either straight or curved.
Where a number of straight lines are required I should put a corresponding
number of Emery wheels on one spindle or shaft and fix the said Shaft in a
machine comprised of two pairs of rollers geared together with a separate small
adjusting table underneath each Emery wheel and so grind a number of grooves by
the simple operation of feeding the material to be operated on through the rollers.
Having now described the nature of my Invention what I claim as new and as of
my Invention is
1. Grooving by Emery wheels in place of steel cutters or saws.
2. The adjustable tables underneath to allow all the Emery wheels to be mounted on
one spindle to be adjusted in any position on the said spindle by means of set screws
or otherwise.

A System of Grooving Strawboard, Wood Pulp, Thick Paper, or
similar Material for Plain or Fancy Box Making or other
Purposes.
I, NATHANIEL BOTT CHADWICK, late of 3 St. Ann's Place, St. Ann's Road,
Stamford Hill, in the County of Middlesex, but now of 29 Lealand Road, Stamford
Hill, aforesaid, Engineer do hereby declare the nature of my said 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 form grooves in strawboard, wood-pulp, thick paper
and analogous materials, for plain, or fancy, box making and other purposes.
In carrying out my invention, I make use of revolving emery wheels, the peripheries
of which are so formed as to correspond to the form of groove required. These wheels
are suitably mounted on spindles in bearings, and caused to revolve at a high speed,
above an iron table, which is made capable of rising and falling, so as to suit the
thickness of the material, the depth of cut required, and to compensate for the wear of
the emery wheels.
The operator places the material to be cut and grooved upon the table, upon which
it is firmly held in the required position, and steadily moved forward under the
revolving wheel or wheels, either in a straight or curved line.
When two or more parallel grooves are required, a similar number of wheels are
mounted on the spindle or shaft.
I also sometimes arrange feeders, consisting of pairs of rollers, between which the
material to be operated upon is passed, and gradually carried forward by the revolution
of the rollers.
And in order that my said invention may be particularly described and ascertained,
reference is hereby made to the accompanying drawings, in which similar letters of
reference indicate corresponding parts.
Fig. 1 is an elevation, and Fig. 2 a section of the cutter. a a a a are feed rollers, to
carry the material to and from the cutter. b is the cutter disc, mounted upon the
boss k, and secured by the nut d and washer n. m is the driving axle to which the
boss kis secured by the set screw l. ee are two parallel bars to which the frame his
secured by the block f, hooked bar o and fly nut i. The block f also sustains the
bar g and block c.
As the material is fed by the rollers a a to the underside of the cutter b, the block c
sustains it in position; and, by means of the screw p, the exact depth of cut can be
regulated, as desired.
The bars e e and the axle m are made sufficiently long to accommodate any number
of cutters that may be required to operate at one time the axle m being driven by any
ordinary gear.

page_text: 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 method of grooving materials for the purposes aforesaid, by means of
revolving emery wheels, substantially as herein before described and shewn on the
drawings.
C₂
2. The application and use of feed rollers a a, revolving cutter b, adjusting blocks
sustained by the bar g, and regulated by the screw p, severally arranged, mounted,
fitted, and operating substantially as herein before described and shewn on the
drawings.
3. The general arrangement and combination of the several and respective parts,
together constituting my invention of "a system of grooving strawboard, wood-pulp,
thick paper, or similar material, for plain or fancy box making or other purposes,"
substantially as herein before described and shewn on the drawings.
