COMPLETE SPECIFICATION.
A New or Improved Machine for Cutting Leather, Cardboard, Veneer,
and other like Materials into Bands or Strips.
I, JOSE MOMPO, of Valencia, Spain, Engineer, 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 :-
My invention relates to a new or improved machine for cutting leather, cardboard,
veneer and other like materials into bands or strips. Such bands or strips may be
employed for many useful purposes. I find narrow ribbons of leather cut by my
machine particularly useful for joining the thin wooden boards used to make boxes
for packing tobacco, oranges & delicate fruits.
The main and essential feature of my invention lies in the use of the circular
cutters hereinafter to be described.
In order that my invention may be more readily understood I shall now proceed
to describe it in detail with reference to the annexed sheets of drawings in which
similar letters of reference indicate similar parts.
Figure 1 is a side elevation,
Figure 2 a front elevation and
Figure 3 a plan of one form of my machine.
As
The machine consists essentially of two metal cylinders Z Z of such form and
construction that they present as shewn alternate annular projections and depres-
sions so as to constitute a series of circular cutters, the projections of one cylinder
entering the depressions of the other cylinder, and the cutting edges engaging like
the blades of a pair of scissors so as to cut any material placed between them.
will be seen the number of separate cutters may be varied at will. In some cases
the cylinders are formed or built up by joining a number of separate discs or
cutters, and these are separated one from another by means of other discs of
smaller diameter the said discs being strung or threaded on a spindle and retained
thereon by nuts screwing on the said spindle in a well known manner. A. wooden
feeding board is placed in front of the two cylinders for the purpose of guiding the
sheet of leather or other material to the cutters. A similar board on the other side
of the cylinders serves for the leading off of the cut strips. The two cylinders are
mounted in bearings on a strong frame as shown. The rotation of the two cylinders
in a contrary direction is produced by gearing at one side of the frame and this
gearing driven from a countershaft in the well known manner shown in Figure 2.
Figure 4 is a part section of built up cylinders with the attached spindles, shaft
and gearing.
Figure 5 represents gearing which may be employed.
Figure 6 represents one of the pinions in the said gearing and like the preceding
figure shows the screw employed to fix the pinions.
Figure 7 shows a comb which I find convenient to employ. It is fixed close to
the cylinders and receives the cut strips as they come from the cutters and prevents
the said strips from becoming entangled with one another.
Figure 8 is a plan view of the said comb.
Figure 9 represents one of the upper transverse bars employed to brace the
frame of the machine as shown in Figure 2.
Figure 10 represents the lower transverse bracing bar also shown in Figure 2.
Figures 11, 12 and 13 show a modified form of my machine which differs from
the form already described in that is better adapted for cutting sheets which are
wider than the cutting cylinders are long. It will be seen that the frame has a
lateral opening at one side so that that part of the sheet which cannot be cut by
the cutting cylinders may pass therethrough and not be crumpled. Of these three

page_text: figures, Figure 11 is a side elevation, Figure 12a front elevation and Figure 13 a
plan. This modified form will be readily understood from what has preceded.
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.
1. In a machine for the purpose specified the employment of cutting cylinders
constructed and arranged substantially as set forth.
2. The arrangement and combination of parts constituting the new or improved
machine substantially as set forth.
3. The modified form of machine substantially as set forth in Figures 11, 12
and 13.
