I JOHN EDWIN SOWERBY of Raglan Street Works, Halifax, in the County of
York, do hereby declare the nature of my said invention for "IMPROVEMENTS IN
APPARATUS FOR BEVELLING OR CUTTING AWAY THE ANGLES OF MILL BOARD WOOD
METAL OR OTHER MATERIAL" to be as follows:-
This invention relates to improved apparatus for cutting away and bevelling or
chamfering the edges of mill boards for book binders and operating in like manner
on wood metal, or other like materials.
The improved apparatus comprises a revolving disc cutter having angled cutting
edge plain or serrated according to the material to be operated upon and rotated
by power treadle or hand wheel-The supporting or holding table consists of an
angled plate or rest having a projecting ledge, one end of the said plate is slotted
or recessed, to allow space for the edge of the cutter, and is placed slightly out of
line to the cutter-The holding table is carried by supports, which readily admit of
either vertical or lateral radial movement being given to the said table so as to set
the same at any desired distance froin and angle to the revolving cutter thereby to
cut away more or less of the angle as desirable-It will be understood that if the
table be a fixture then the rotary cutter will be made adjustable.

Agent for the Applicant.

I JOHN EDWIN SOWERBY, of Raglan Street Works, Halifax, in the County of
York, do hereby declare the nature of my said invention for "IMPROVEMENTS IN
APPARATUS FOR BEVELLING OR CUTTING AWAY THE ANGLES OF MILL BOARD, WOOD,
METAL, OR OTHER MATERIAL" 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 away and bevelling or
chamfering the edges of mill boards for book binders and operating in like manner
on wood, metal, or other like materials.
Such being the nature and object of my said invention, the following is a
complete description of same reference being had to the accompanying drawings
forming a part of this specification, in which—
Fig. 1 is an end elevation of a machine in accordance with my invention.
Fig. 2 is an elevation of the right hand end of the machine.
At 1 is the framing of the machine carrying the shaft 2 on one end of which is
the balance wheel 3 on the other end is the circular cutter 4 having angled cutting
edge plain or serrated according to the material to be operated upon-5 is a driving
pulley for imparting rotation to the shaft and cutters by means of cord or strap
from the driving pulley or by treadle the latter being quite efficient for ordinary
thicknesses of millboard-The table on which the material to be cut or operated
upon is placed comprises the angled plate 6 having an opening or recess under the
edge of the knife to allow the latter to cut through and slightly below the under
edge of the material operated upon-The table plate 6 is carried by the bracket 7
its convex part 8 being during adjustment moved in the arc or concave holder 9 on
the supporting stud or pin 10-At 11 is a nut for clamping the parts 8. 9. together
when adjusted-The bolt 12 admits of the adjustment of the plate 6 in its
supporting bracket, the guage thumb screw 13 passed through the lug 13 of the
plate 9 is for securing required adjustment of parts 6. 7. 8. 9 in a lateral direction,
the screw 14 is for adjusting vertically the stud 10 and table 6 and the screw 15 is
a binding or holding screw for the stud 10-At 16 is a bracket and clamp 17 for
carrying a file 18 or stone for sharpening the circular cutter 4-19, 20 and 21 are
screws for adjusting the said bracket.
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 general construction combination and arrangement of the parts con-
stituting the improved machine for purpose aforesaid and as herein described and
illustrated by the drawings annexed.
2. The table adjustable as illustrated and described and in combination with the
circular cutter for purpose set forth.
