PROVISIONAL SPECIFICATION,
Improved Apparatus for Cutting and Sawing Grooves or Slots in
Plates, and for other similar purposes.
CHARLES WALMSLEY AND
We CHARLES WALMSLEY, Engineer, and
COMPANY LIMITED, Machine Makers, both of Atlas Iron Works, Elton, Bury,
in the County of Lancaster, do hereby declare the nature of this invention to be as
follows:-
This invention relates to improved apparatus for cutting and sawing grooves or
slots in metal plates or other articles or for similar purposes such as cutting or
milling the surface of articles.
The apparatus consists mainly in mounting a series of circular or rotating cutters
upon a suitable shaft or spindle carried by a swinging arm or frame the action of
the cutters being regulated by a roller (or rollers) loose on the said shaft or spindle
(or otherwise suitably mounted on the said arm or frame) and riding or resting
upon a suitable "former" or surface, fixed to or formed with the support of the
article under operation.
The invention is specially desigued for cutting and sawing grooves in plates for
straining purposes, such as for straining paper pulp; and for this purpose the
apparatus is constructed as follows:-
The driving spindle or mandrel also forms the centre upon which the aforesaid
swinging arm or frame is mounted and is supported at one end by a suitable fixed
bracket and at the other end by the end of a spindle or driver.
A spur wheel is keyed on the last named end of the driving spindle or mandrel
and gears with a similar wheel or pinion on the shaft or spindle on which the
cutters are fixed at equal and suitable distances apart.
The plate under operation is mounted upon a suitable table capable of sideways
adjustment and endwise motion-and to or at either sido of this table is fixed or
made a "former" plate on the indented surface of each of which rides or rests
a bowl or roller of suitable width mounted loosely on the cutter shaft or
spindle.
The swinging arm or frame may be weighted if necessary; and when it is
lowered by the "former" plate the cutters will cut the plate under operation,
the length of the cut made being determined by the depression on the edge of
the "former."
"
When one series of cuts have been completed the table and the plate under
operation is moved or adjusted sideways for the required distance and the
operation recommenced, the loose rollors on the cutter shaft being sufficiently
broad to allow of this sideways adjustment of the "formor," on the table beneath
the said rollers.
It will be evident that the "formers" may have a curved or circular surface if
the plate or article under operation is curved or cylindrical and a corresponding
motion.will in such case be given to the support of the article under operation.

Plates, and for other similar purposes.
We CHARLES WALMSLEY, Engineer, and CHARLES WALMSLEY_AND
COMPANY LIMITED, Machine Makers, both of Atlas Iron Works, Elton, Bury,
in the County of Lancaster, 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 :-
This invention relates to improved apparatus for cutting and sawing grooves or
slots in metal plates or other articles, or for similar purposes such as cutting or
milling the surface of articles.
'The nature of our said invention and the manner in which the same is to be
performed or carried into practical effect will be readily understood on reference
to the sheet of drawings annexed and the following explanation thereof.
Fig. 1 on the drawing is an elevation, Fig. 2 a plan view, and Fig. 3 a transverse
section of our improved apparatus, Fig. 4 is a partial plan view showing a
modification thereof hereinafter more particularly described.
b
The invention consists mainly in mouuting a series of circular or rotating
cutters a upon a suitable shaft or spindle 6 carried by a swinging arm or frame c,
the action of the cutters upon the plate d being regulated by a roller (or rollers e)
loose on the said shaft or spiudle 6 (or otherwise suitably mounted on the said arm
or frame c) and riding or resting on the upper face or edge of a suitable "former"
or surface fixed to or formed with the table or support g on which the plate or
other article d under operation is carried.
The apparatus as shown on the drawings is specially designed for outting and
Bawing grooves or slots in plates for straining purposes such as those used for
straining paper pulp or other materials and for this purpose the apparatus is
arranged as follows:-
The driving spindle or mandrel h also forms the centre upon which the aforesaid
swinging arm or frame o is mounted, and is supported at each end by suitable fixed
brackets and has at one end a series of graduated driving pulleys k driven by a
strap from overhead or other convenient shafting, or it may be otherwise driven.
A spur wheel is keyed at or near the other end of the driving spindle or
mandrel hand gears with a similar wheel or pinion m on the end of the shaft or
spindle b on which the cutters a are fixed at equal and suitable distances apart.
The plate d under operation is mounted upon a suitable table capable of
sideways adjustment and end wise motion, and to or at either side of this table is
fixed or made a "former" plate on the indeuted upper surface of each of which
rides or rests a bowl or roller e of suitable width mounted loosely upon the cutter
shaft or spindle b.
The swinging arm or frame c may bo weighted if necessary, and when it is
lowered by the "former" plate the cutters a will cut grooves or slots in tho
plate d under operation, the length of the cut being determined by that of the
depression on the upper edge of the "former" f.
When one series of cuts have been completed the table g.and the plate d under
operation is moved or adjusted sideways for the required distance and the operation
recommenced, the loose rollers e on the cutter shaft b being sufficiently broad to
allow of this sideways adjustment of the "former" on the table g beneath the
said rollers.
It will be evident that the "formers "f may have a curved or circular surface

page_text: if the plate or article under operation is curved or cylindrical and a corresponding
motion will be in such case given to the support of the article under operation.
In some cases (especially when rapidly driven saws are substituted for the
cutters a) we dispense with the toothed wheels or pinions and m and drive the
cutter or saw spindle independently (as shown at Fig. 4) by affixing a small
grooved pulley thereon and driving the same by an endless band from any
convenient pulley on the shafting.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we doclare that what
we claim is :-
The improved apparatus for cutting and sawing grooves or slots in plates and
for other similar purposes substantially as herein before described and illustrated by
the drawings annexed, and more especially we claim in such apparatus the
combination of the "former" plates, attached to the table, with the swinging arm
or frame supporting the cutter spindle, together with the loose rollera mounted on
the latter and riding on the upper surface of the said "former" plates.
