COMPLETE SPECIFICATION.
An Improved Machine for Cutting Patterns and the like of Woven
Fabrics, Paper, Cardboard, and similiar Materials.
I, FRANZ VETTERLING, of Wiesbaden, in the Empire of Germany. 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:-
The improved machine consists of a lever cutting apparatus particularly
applicable for cutting a number of thicknesses of woven or other fabrics or materials
such as paper or cardboard into patterns or small pieces for various purposes.
And in order that my invention may be fully understood and readily carried into
effect I will describe the accompanying sheet of drawings reference being had to
the figures and letters marked thereon.
Fig. 1 is a front elevation, Fig. 2 an end elevation, partly in section, and Fig. 3 a
plan of the improved machine.
In the drawings,-a represents the frame of the machine, the knife carrier or
movable portion to which the knife or cutting blade is secured and d d guide
pieces bolted to the base of the machine by bolts d'; ee are two studs which screw
into the frame a and pass through slots in the knife carrier band through holes
in the guide pieces d, and winged nuts e¹ on these studs serve to adjust the knife c
and prevent it falling by gravity.
on
A hand lever is fulcrumed on a study secured to the frame a and a pinion f
this handle is in gear with a rack 2 cast or formed with the movable knife carrier b.
The materials to be cut are laid upon the base of the machine in the desired position
where they are securely clamped by turning by means of a hand wheel ½ a screw h¹
which passes through a nut in the top of the frame a and carries below a cross
rail i fitted in guides a' in the pillar a² of the frame; the knife carrier b and knife c
are then brought down by moving the handle ƒ to the right hand and the material
is cut.
Instead of having a stationary adjustable clamping device as described, I might
as an alternative arrangement have a movable presser for the materials to be cut,
the said presser being connected adjustably to the knife carried 6 so as to move up
and down with the latter when actuated by the hand lever f.
In order to cut the edges of the fabric at right angles with one another, and of
any required length the base of the machine is marked with guide lines parallel
with and at right angles to the knife.
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. A lever cutting machine consisting in its essential features of a frame, a knife
and means for adjusting the same, a knife carrier with inclined rack actuated by a
pinion and hand lever for the purpose of cutting woven fabrics, paper, and the like,
substantially as herein described with reference to the accompanying drawings.
2. The general arrangement and combination of parts constituting an improved
machine for cutting woven and other materials such as paper and cardboard,
substantially as herein described and as illustrated by the accompanying drawings.
Dated this 29th day of August 1893.
