Improved Machinery for Cutting Leather, specially Applicable for:
Cutting and Trimming the Edges of Bag Handles, and other
Articles Made of or Covered with Leather.
I, WILLIAM MARSH, of 218 Jubilee Street, Mile End Road, in the County of
Middlesex, Fancy Leather Goods Manufacturer, do hereby declare the nature of
this invention to be as follows:-
This invention relates to machinery for cutting leather, and more especially for
cutting and trimming the edges of articles made of, or covered with, leather, such
as the handles of "Gladstone" and other travelling bags, and the like; but the
said machinery is also applicable for cutting leather for other purposes.
The machinery consists of a knife having an oblique or inclined edge, and caused
to reciprocate in the direction of its length, and more or less at right angles to a
bed or support on or against which the article that is to be cut or trimmed rests
while it is being operated upon by the reciprocating knife. The knife passes
through a slot in the bed or support, or in a suitable feeding device, somewhat
like the feeding device of a sewing machine, which is provided for feeding the
article to be operated upon up to the knife edge as the latter reciprocates.
It will be understood that as the oblique or inclined edge of the knife stands
at an angle with the line of reciprocation the knife, at each downward stroke, cuts
the object presented to it, to an extent dependent upon the angularity of the edge,
and the length of stroke of the knife, and the object being operated upon is fed
forward by the feeding device as the knife riess, so that at the next descent of
the knife it will make another cut, and so on. The knife and feeding devices may
be operated by any suitable mechanism, and if required a plurality of knives and
feeding devices may be employed to enable the object to be operated upon to be
cut at several points at once.

Improved Machinery for Cutting Leather, specially Applicable for
Cutting and Trimming the Edges of Bag Handles, and other
Articles Made of or Covered with Leather.
I, WILLIAM MARSH, of 218 Jubilee Street, Mile End Road, in the County of
Middlesex, Fancy Leather Goods Manufacturer, 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 machinery for cutting leather, and more especially for
cutting and trimming the edges of articles made of, or covered with, leather, such

page_text: as the handles of "Gladstone" and other travelling bags, and the like; but the
said machinery is also applicable for cutting leather for other purposes.
The machinery consists of a knife having an oblique or inclined edge, and caused
to reciprocate in the direction of its length, and more or less at right angles to a
bed or support on or against which the article that is to be cut or trimmed rests
while it is being operated upon by the reciprocating knife. The knife, passes
through a slot in the bed or support, or in a suitable feeding device, som
Somewhat
like the feeding device of a sewing machine, which is provided for feeding the
article to be operated upon up to the edge of the knife as the latter reciprocates.
And in. order, that the said invention may be fully understood I will proceed
to describe the same with the aid of the accompanying sheet of Drawings, which
Drawings illustrate, by way of example, how the invention can be carried into
effect by means of a sewing machine altered so as to suit the purpose in view.
Figure 1 is a side elevation of so much of the head and work plate of an ordinary
sewing machine as is necessary to elucidate the application of the invention
thereto.

Figure 2 is a sectional plan taken on the line X-X of Figure 1, and Figure 3
is a front elevation partly in section.
: A is, the fixed front of the head of the machine, B the lever operating the ver-
tically reciprocating needle bar C which is in this case adapted to receive and carry
the reciprocating knife D instead of the ordinary sewing machine needle. E shows
part of a work-plate provided with a slot F for the knife D to work through, and
with a serrated feed piece G reciprocating in a guide piece G and operated by
a lever H-to which it is attached by the screw Hor in any other suitable way.
The feed piece G is also provided with a slot G2 for the knife D to pass through.
I is a presser foot similar to that usually employed in sewing machines but
provided with a slot I' for the knife D to work through. J in Figures 1 and 2
represents in dotted lines part of the handle of a "Gladstone" bag with one of its
edges, which has to be trimmed by the knife D, resting on the guide piece G
fixed to the work plate E.
It will be understood that as the oblique or inclined edge of the knife D stands,
as shown in Figure 3, at an angle with the vertical line of reciprocation of the
bar C, the said knife at each downward stroke, cuts the object presented to it, to
an extent dependent upon the angularity of the edge, and the length of stroke of
the knife, and the object being operated upon, such as J for example, is fed
forward by the feeding device G as the knife rises, so that at the next descent of
the knife it will make another cut, and so on.
If required a plurality of knives may be employed to enable the object to be
operated upon to be cut at several points at once. For example as shown in
Figures 1 and 2 several knives D, D may be mounted on one cross head K
connected to the vertically reciprocating bar C, the work plate E, feed piece G
and presser foot I being respectively slotted to allow the knives to work through
them. This last described arrangement is suitable for cutting up leather into a
number of strips at one operation.
It is obvious that instead of using the mechanism of a sewing machine for the
purpose of utilizing my invention any other suitable mechanism may be employed
for operating the knife or knives and the feeding mechanism, and that the latter
may be of any suitable intermittently acting type.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:
First. Machinery for cutting leather which consists of a knife having an oblique
or inclined edge, and caused to reciprocate in the direction of its length more or
less at right angles to a bed or support on or against which the article to be cut
or trimmed rests while being operated upon by the reciprocating knife, sub-
stantially as described..

page_text: Second. Machinery for cutting leather which consists of a knife having an
oblique or inclined edge, and caused to reciprocate in the direction of its length,
or of a plurality of such knives, and an intermittently acting feed device, combined
and operating substantially as described.
