PROVISIONAL SPECIFICATION.
Improvements in Machines for Skiving Shanks for Boots and Shoes
and the like.
JOHN EDMUND HODGSON, Montague Street, Kettering, Engineer, do hereby declare
the nature of this invention to be as follows:.
In my invention I employ a knife or knives of improved design which when
attached to a skiving machine of the ordinary construction renders it capable of
cutting or skiving both edges of the leather or other material used for the shank
at the same time thus completing the shank at one operation
instead of two as is now usual. To do this I usually employ
Vee shaped knife, this is fixed so as to cut the shank on issuing from the feeding
rolls & skives it on both sides at the same time, I can also obtain the same result
by the use of two or more knives suitably fixed instead of the one knife.

Improvements in Machines for Skiving Shanks for Boots and Shoes
and the like.
I, JOHN EDMUND HODGSON, of No. 10, Montague Street, Kettering, in the County
of Northampton, Engineer, do hereby declare the nature of this invention and in
what manner the same is to be performed, to be particularly described and ascer-
tained in and by the following manner: -
My invention relates to a machine for skiving boots, shoes and the like, and has
for its object to improve the construction of such a machine so that it will be capable
of cutting or skiving both edges of the leather or other material used for the
shank at the same time, thereby completing the shank in one operation.
According to my invention I provide a knife which is V-shaped in cross section,
this is mounted on a skiving machine of any suitable construction in such a
manner that the shank on issuing from the feed rolls is skived on both sides at the
same time. In place of a single V-shaped knife I may obtain the same result by
providing two or more knives if desired."
In the accompanying drawing.
Figure 1 is a front elevation of a well known form of skiving machine fitted with
my improved knife.
Figure 2 is a plan, Figure 3 a rear elevation, and Figure 4 a side view of the
V-shaped knife and its securing means detached from the machine and drawn to
an enlarged scale.

page_text: Referring now to Figure 1, A. is the frame of the machine, B B¹ the feed rolls.
C is a knife V-shaped in cross section, which is held in a clamp D. Said clamp
is pivotally supported so that the position of the knife edges can be adjusted with
reference to the feed rolls. The knife is furthermore provided with a slot through
which the clamping bolt passes, so that it can be moved nearer to the feed rolls
when its edges have become worn away by repeated sharpening. The details and
shape of the knife will be readily understood on reference to Figures 2 to 4 in which
D is the fixed portion of the clamp which is pivotally secured to the frame work of
the machine, this part being formed with a groove Di to fit the knife. E is a block
into which the clamping bolt E¹ is screwed. Said clamping bolt passes through
a slot in the knife and a slot D³ in the fixed part of the clamp D.
In place of a single V-shaped knife I may obviously employ two knives inclined
to each other, a suitable construction of clamp being provided in this case.
It will be readily understood that on passing a shank between the feed rolls the
two edges of the knife will skive the same on both sides at the same time, thereby
completing in one operation what has hitherto required two operations.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:-
A machine for skiving shanks for boots, shoes and the like, fitted with a knife
V-shaped in cross section or with two knives adapted to skive both sides of the
shank at one time, substantially as described.
