Improvements in or relating to Machinery for Cutting Leather
and the like.
I, FREDERICK OUTLAN, Engineer, of Wellingborough, in the County of
Northampton, do hereby declare the nature of this invention to be as follows:--
This invention relates to machinery for cutting leather and the like, particularly
to those known in the trade as ranging machines and skiving machines.
The object of this invention is to effect an improved construction of such
machines by which the same machine may be used either for ranging or skiving
and also to effect improvements in details of such machines, as for instance, in
the knife, the fence, and the bed, which improvements may be applied to
existing machines.
According to this invention the ranging machine is provided with a circular
knife which operates in much the same way as a circular saw, that is to say the
circular knife is rotated close to a bed on which the material to be cut is placed.
A guide or fence is preferably arranged upon the bed to ensure uniform cutting
of the material. By this arrangement the feed rollers usually employed in a
ranging machine may be dispensed with, the circular cutter operating to draw
the material forward.
In the skiving machine a circular knife is also employed and similarly operated,
and it is preferred to so proportion and arrange the parts that the same machine
may be employed either for skiving or for ranging by effecting the desired altera-
tion in the guides or fences by which the material is supported or guided, and
if necessary by changing the knives. One construction of machine according to
this invention will now be described by way of example.
A horizontal rising and falling bed is attached to a frame which also supports
a horizontal shaft, to one end of which and just above the bed is secured a circular
knife. This knife is preferably made so as to be readily detachable, and if the
machine is to be used as a ranging machine, the edge may be bevelled from both
faces, but if it is intended to be used as a skiving machine it is preferred to
bevel the edge of the knife from one face only leaving the other a plane surface.
The bed is provided with a groove or slot into which the lower edge
of the knife enters, and the material is fed forward to the knife from that side
from which, by the rotation of the knife, it will be drawn onward. By this means,
when used as a ranging machine, the rollers which are usually employed to feed
the material to the fixed knife may be dispensed with, the circular knife according
to the present invention serving the purpose of both feed rollers and cutter.
adjustable fence or guide is preferably secured to the rising and falling bed so
as to regulate the width of the strip of material cut, and to ensure parallelism
of the edges. When used as a skiving machine the knife is preferably so attached

is

thickness of material, and is arranged with a guiding surface inclined at an angle
to the rising and falling bed. This angle may be adjusted by any convenient
means, and the fence is so placed upon the bed as to leave a space between it
and the front face of the cutter, into which space the leather is fed. By adjusting
the distance of the fence from the face of the cutter any desired thickness of
leather may be skived, and by adjusting the angle of the guide surface with the
bed the leather may be skived to any desired angle. A spring is preferably pro-
vided which presses the leather against the skiving fence or guide and so ensures
a uniform cut. A guard may conveniently be attached to the machine to enclose
the upper edge of the knife and so protect the operator from accidental injury.

Improvements in or relating to Machinery for Cutting Leather
and the like.
I, FREDERICK CUTLAN, Engineer, of Wellingborough, in the County of
Northampton, 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:-

accidental contact with the upper portion of the knife.
It is obvious that various alterations may be made in machines of the kind
described, without departing from the spirit of this invention, the construction
illustrated in the accompanying drawings being merely by way of example.
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. A machine for cutting leather and the like having a rotating circular knife
and so arranged that it may be used either for ranging or skiving.
2. A machine which may be used either for ranging or skiving having a
rotating circular knife and provided with a rising and falling bed for the purpose
described.
3. In a skiving machine a guide-fence having an adjustable face for the purpose
described.
4. A skiving machine in which the angle or depth of the bevel may be adjusted
substantially as described.
5. In a skiving machine guiding the leather by means of a spring which presses
it against a fence having an adjustable face.
6. The complete machine for skiving or ranging substantially as described or
illustrated in the accompanying drawings.
