PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Cutting Patterns from Cloth and
like Materials.
I, MARTINSON CRAMBY, of 34 Tyrrel Street, Bradford, in the County of York,
Tailor and Woollen Draper, do hereby declare the nature of this invention to be as
follows:-
This invention has for its object the cutting of cloth and like materials into small
pieces suitable for patterns, with greater facility than hitherto; and consists in
mounting one or more rotating knives on a shaft above a table having slits for the
reception of the lower portion of the respective knives, and a rotary knife arranged
to pass along and cut the cloth or the like in a transverse direction.
The apparatus is applicable for cutting a number of thicknesses placed together
and fed to the cutting knives by rotating grooved press rollers suitably connected
to the driving shaft, the cutting knives dividing the cloth in a longitudinal
direction.
The pieces of cloth or the like are cut transversely by a rotary knife mounted
upon a spindle, upon which is secured a pinion gearing into a rack, and upon the
said spindle is secured a handle, by the turning of which, a rotary and travelling
motion is given to the knife along the thicknesses of cloth, and so cut through to
any required size.
In order to secure the cloth when cut transversely, a press bar regulated by
springs to suit the various thicknesses of cloth or the like to be cut, is applied to
the same at each side of the rotary circular knife, thus pressing down the cloth or
the like firmly to the bed or table of the machine.

COMPLETE SPECIFICATION.
Improvements in Apparatus for Cutting Patterns from Cloth and
like Materials.
I, MARTINSON CRAMBY, of 34 Tyrrel Street, Bradford, in the County of York
Tailor and Woollen Draper, 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 has for its object the cutting of cloth and like materials into small
pieces suitable for patterns, with greater facility than hitherto.
In order that my invention may be fully understood, I will describe the same in
detail by making reference to the accompanying drawings, in which
Fig. 1 represents a side view of my improved apparatus.

page_text: secured the arms G. each arm having a guide roller H mounted thereon. The
before mentioned shaft C. is provided with a spur wheel J. gearing into spur
wheel K secured on the supporting roller L: upon the end of which is loosely
mounted a hand wheel M having a chain wheel M' mounted on the boss of same
and which is connected to chain wheel M³ secured on shaft C by driving
chain M³.
Upon operating the hand wheel M. tho shaft C is driven by the chain M³ and
the supporting roller L is driven through the spur gearing J and K.
To the opposite end of the roller L is secured a chain wheel L' a similar wheel
is also secured on the roller O. and the two wheels connected together by chain L³,
thus ensuring a constant feed to the cutting knives in the manner as hereinaffer
described.
The material to be ent.into patterns is supported and carried to the rotating
knives D. by the travelling bands N passing round the rollers O. O¹ and L. when
it is cut by the revolving knives D into longitudinal strips.
The material is carried forward and delivered on the table P. above which is an
adjustable cutting knife Q secured on shaft R supported by movable bracket S.
free to slide on cross bars T. T. secured to the sleeves U. U. on the upright
studs UU. On the said shaft R is secured the pinion V gearing into rack V'
also secured to the sleeves U. U.
To the before mentioned sleeves U. U. are attached the links W. W. the
opposite ends being respectively connected to levers. W₁ W₁ secured to the
shaft W passing across the machine. One of the said levers W₁ is extended,
terminating with a handle X. and upon turning the lever by the said handle to the
position shown by dotted lines, the sleeves U. U. rack Vi and travelling cutting
knife Q. in connection therewith are lowered to such an extent as to bring the
presser plate Y on to the material resting on the table P. for securely holding the
same thereon.
Upon turning the hand lever R' secured on shaft R. the knife Q receives a rotary
and travelling motion, thereby cutting the material in a transverse direction by the
rotating circular knife Q.
The presser plate Y is free on the bars B' and suspended at each end by the said
bars which are secured to the respective sleeves U. and is provided with springs Z
between said plate and rack VI. On placing the material on the table P to be cut
in a transverse direction, and lowering the rack V₁ and press plate Y. in the
manner described, the plate Y. secures the material in its required position, the
springs Z allowing for varying and irregular thicknesses of material placed on
the said table.
Having now particularly described and ascertained the nature of this inven
tion, 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
substantially as and for the purpose hereinbefore set forth and illustrated by the
accompanying drawings.
2. In a pattern cutting machine, the combination of the travelling cutting
knife Q. pinion V. rack V¹ presser plate Y with the links W. W. all arranged
substantially in the manner and for the purpose hereinbefore set forth.
