PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Cutting Patterns of Cloth and other
Materials.
MARTINSON CRAMBY, of 22, Valley Street, North Street, Leeds, in the County
of York, Mechanic, do hereby declare the nature of this invention to be as
follows:
This improved invention has for its object the cutting of cloth and other like
materials into small pieces suitable for patterns or otherwise with greater facility
than hitherto and consists in the mounting of one or more circular or straight
knives on a shaft or spindle, the above knives running between two steel plates
having cutting edges.
These knives divide the cloth in either a transverse or longitudinal directions.
This apparatus cuts one or more thicknesses and the material is fed to the
knives by rotating grooved rollers or endless bands suitably connected with the
driving shaft. The knives are mounted on a spindle geared to a rack by a pinion.
On the spindle is attached a handle by turning which (either by hand or power)
a rotary or other travelling motion is given to the knives which thus make a clean
cut through the material. In order to secure the cloth when cutting a press bar
regulated by springs holds the material firm on the bed or table of the machine.
Special provision is made for the complete cutting of the patterns without
changing or reversing the material to be cut.
This is done by means of a longitudinal and transverse groove between the two
steel plates before mentioned and which plates are fixed in the bed of the machine
the press bars answering to the grooves as conductors for the knives.

Improvements in Apparatus for Cutting Patterns of Cloth and other
Materials.
I, MARTINSON CRAMBY, of 22, Valley Street, Leeds, in the County of York,
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:-
This invention is an improvement on Specification No. 8188, dated 2nd August,
1893, and has for its object the cutting of cloth and like materials into pieces suit-
able for patterns and otherwise with greater facility than hitherto.
In order that my improved invention may be fully understood, I hereby describe
the same in detail by making reference to the accompanying drawings, in which
Pine 71

page_text: Figure 2 is a plan of same.
Figure 3 is a side view.
Figure 4 is a
cross section of cutter box and bed.
Figure 5 is a view of cutter box with front removed.
Figure 6 is a modified form of my machine.
The frame of the machine is indicated by the letter C, and is suitable for rest-
ing on a table or other support. To the said frame or bed C, are secured supports
or pillars P, to which are attached guide bars E E', along which the cutter
box A carrying a straight or other shaped cutting knife B, travels in a groove in
bed C for cutter knife B; on the edges of said groove are steel plates with
cutting edges. The handle I is secured to crank shaft K, on turning which a
reciprocating motion is given to the slide N, along with blade or knife B. On
crank K is also secured a wheel L, geared into wheel J, upon the boss of which is
fixed the wheel M, gearing into the rack F, thereby giving a horizontal travelling
motion to the cutter box A, and a reciprocating motion to the cutter knife B.
* Handle Q is attached to shaft R, at each end of which are links S S. The opposite
ends of said links fit on to pins secured to brackets G G¹, carrying springs HH',
and press plate D. The material to be operated upon is placed on the feed
apron Q. Handle T attached to roller, U feeds forward the material, whilst
handle is in position dotted in Figure 2. After feeding the requisite amount
of material forward, handle Q is reversed to position shown in full Figure 2,
causing the pressure bar D to descend supports or pillars PP, which securely holds
the material, whilst handle I is turned giving a reciprocating motion to the blade
or knife B, along with a horizontal motion across the bed C, thus cutting the
material into small strips for patterns or otherwise.
Fig. 6 shows a modification of the above pattern cutting machine, dispensing
with the cutter box A, and knife or blade B. A hand knife as shown at W, is
used by the operator instead. The machine consists of bed C, pressure bar or
plate D, spring H H, supports P P links S S, handle Q, shaft R, and slide
brackets G G. The material being placed on apron O, is carried forward under
the press bar D, and firmly held whilst knife W is drawn across the bed C along
the groove. Straight or other shaped blades similar to the foregoing may be fixed
transversely suitably attached, so that the material may be cut both transversely
and longitudinally thereby cutting the material into patterns or otherwise. Any
number of thicknesses may be cut at one operation. The frame on which the
apron runs as feeder, is jointed, folding into a compact form, and is clamped to
the back of the bed of the machine, and requires no refixing, but is ready for
immediate use.
Having now particularly described and ascertained the nature of this improved
invention, and in what manner the same is to be performed, I declare that what I
claim is :
1. The combination of the parts forming the complete apparatus arranged sub-
stantially as and for the purpose hereinbefore set forth and illustrated by the
accompanying drawings.
2. In this improved pattern cutting machine, the combination of the travelling
and reciprocating cutting knife or blade B, brackets G G, springs H H, crank K
slide N, pinion M, rack F, press plate D, links S S, wheel L, all arranged sub-
stantially in the manner, and for the purpose hereinbefore set forth.
Dated this 5th day of April 1899.
