Improvements in Boot and Shoe Machinery.
I, WALLIS ASKHAM, of 55, Havelock Street, Kettering, in the County of
Northampton, and 11, Castle Street, Sneinton, in the County of Nottingham,
Machine Builder, do hereby declare the nature of this invention to be as
follows:-
A welt cutting machine with grooving bevelling and skiving appliances
attached and so arranged that the four operations are performed simultaneously.
In carrying out my invention I construct a machine with three rollers. One
with a plain surface and two with grooved or toothed surfaces to form feeders
and placed in such positions that the plain roller forms a centre. The two
toothed or grooved rollers. One in a perpendicular above. The other in a
horizontal position behind. The inner surfaces of these rollers forming a semi-
circle. These rollers are on shafts or spindles and are geared together with
toothed wheels supported in a frame. The upper and back rollers having adjust-
able bearings with springs on them to allow them to rise and fall according to
the thickness of leather that is placed between them.
On the aforesaid frame I attach knives held in blocks that can be adjusted
into different positions for the purpose of cutting to a certain width. Grooving
to the required depth, bevilling one or both edges, and shaving or skiving to
the desired thickness the leather that is thus passed through the machine. Being
lead to theese required positions by movable or fixed guides. Having ascertained
the nature of my said invention, what I claim is the production of a finished,
welt by passing it through the machine only once thus accomplishing the four'
operations at one and the same time, as herein substantially discribed.
Dated this Eighth day of September 1898.

I, WALLIS ASKнAм, Machine Builder, of 8, Havelock Street, Kettering, in the
County of Northampton, and Thorsely House, Colwick Road, Sneinton, in the
County of Nottingham, formerly of 55, Havelock Street, Kettering, and 11, Castle
Street, Sneinton, Nottingham, 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:-
-
A welt cutting machine with skiving grooving and bevilling appliances attached
and so arranged that the four operations are performed simultaneously.

A, is machine frame.
B, Top roller on shaft B1, and wheel B'2.
B3. Bottom feedroller on shaft B4, and wheel B 5.
B 6. Back feed roller on shaft B7 and wheel B 8, all driven by pinion wheel B 9,
on pulley B 10.
C. Splitting knife block, fitted to frame A.
C1. Splitting knife, held in position by clip C2, and screws C3, and C4, and
top roller clearing fork C5, held in position on knifeblock C, by screw C6.
D. Sliding skiving knifeblock, fitted to frame A.
D1. Skiving Knife, locked in position by screw 12, when adjusted between
rollers B, and B3, by screws D3. Said skiving-knife D1, in block D. Raised
or lowered to thickness of material required by screwed spindle D4, and wheel D 5,
Geared into a simular tooth wheel D D, on pressure spring cap of movable bear-
ing 00, of top roller B, for the purpose of giving one and the same tension on
roller B, when cutting thick or thin material.
D6. Lever and screw for securing skiving knife block. D, when adjusted as
required.
E. Table, fence and guide combined. Fence-part shown marked E, in Fig. 1
Sheet 1. Table of same E, Fig. 2, Sheet 1, and Fig. 3 Sheet 2.
E1. Back staypin to guide fence E, passing through frame A, is attached to
crosplate E2, by screw E4, at one end, and the opposite end is inserted in a
hole bored partly through guide E, Fig. 3, Sheet 2, to prevent guide E, from
springing away from its position, thus keeping the welts equal widths after
leaving roller B, down between rollers B3, and B 6.
E3. Thumbscrew, for holding guide and table in position when set for various
widths of welts.
F. Backroller bearing.
F1. Adjustable screw on spring cap F2.

G: Grooving knife holder.
G 1. Grooving knife, held in position by clip and screw G2, and G3, when
adjusted between rollers B3, and B6, by screw G4, said knife G1, shown in
groove of roller B6, Fig. 1, Sheet 1.
G5 and G 6, are screws for setting knife.

H. Bevilling knife.
H1. Bevilling knife holder. H2, and H3, clip and screw for holding same at
any angle when set by pin H4, and adjusted by screw H 5.
H6. Delivery guide.
I. Adjusting presure screw on spring.
I 1. Screw for adjusting top gear wheel on roller B.
The machine is so constructed that the top roller B, on shaft B 1, can be raised
or lowered by means of an adjusting screwed spindle D4, that passes through
the top of sliding knife block D. Said block having a projecting lug 0, to
lift movable bearing 00, of top feed roller B, for the purpose of keeping top
roller from damaging knife D 1, that is to say that by adjusting knife block D,
to the thickness of material required the roller and bearing is carried up or down
by said lug 0. But at the same time giving an independant rise of bearing 00,
for rough material passing under roller B, and over B3, shown in Fig. 3,
Sheet 2, and more clearly in Fig. 4, Sheet 2.
The operation is as follows.
The material is placed on table E, up to fence, and is carried forward between
rollers B, and B 3, on to splitting knife C1, and skiving knife D1, thus cutting
and shaving the material to the desired width and thickness the surplus material
passing over skiving knife D 1. The partly prepared welt going under said
knife D1, between guides and rollers 133, and B6, on to grooving knife G 1, and
bevilling-knife H, same being delivered a finished welt over delivery guide H 6.
I do not confine myself exclucively to bevil and groove, as welts are required
without grooves, and in some cases without bevils.
Having now particularly described and assertained the nature of my said
invention, what I claim is:-
First the construction and general arrangment of a machine or apparatus as
shown in accompanying drawings and for the purpose herein before described.
Second, the production of a finished welt by passing it through the machine
only once, thus accomplishing the four operations at one and the same time.
Dated this Ninth day of September One thousand eight hundred and
ninety eight.
