Improvements in Apparatus for Copying Letters, Writing, and other
Delineations.
I, BENJAMIN JOSEPH BARNARD MILLS of 23 Southampton Buildings in the
County of Middlesex, Patent Agent, do hereby declare the nature of this inven-
tion, a communication to me by Leon Mulwidson of 5 Knesebeckstrasse,
Charlottenburg near Berlin, in the Empire of Germany, Manufacturer, and in
what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement, reference being had to the accom-
panying drawing and to the figures and letters inarked thereon:-
This invention relates to a copying apparatus differing from those hitherto in
use by the fact that it can be used in any place, a hook or any projection being
sufficient to fix it in position for use.
In the accompanying drawing,
Figure 1 is a front elevation and Figure 2 is a side elevation of a copying
apparatus constructed according to the invention and
Figures 3 and 4 represent various positions of the same showing the several
parts thereof in their relation to one another when the apparatus is being used.
An apparatus of this kind substantially consists of a strip a of cloth or other
fabric rectangular in form, which serves as the pressing material. Any suitable
cloth or fabric may be used, but that which is preferred is a sheet of india rubber.
At the top and bottom sides of the said pressing cloth there are pairs of semi-
cylindrical laths b joined together by means of wood screws c, forming when united
a rod b. This rod 6 may be made of any suitable material either solid or hollow.
The ends of the upper rods b are attached to a cord.
In the middle of this cord there are two knots dd, which are close together.
The apparatus is used in the following manner. The copying book e has a
linen cover.
After the writing to be copied and the usual waterproof sheets have
been put into the book the latter is placed with the back lying parallel with the
laths as shown in Figure 3, upon the strip of cloth a, so that the lower lath b, in
winding round the copying book shall lie some little distance from the back. Then
the string d is passed over a book for some such other contrivance. The copying
book e is then wound up together with the cloth a, so as to bring them into the
position shown at Figure 4. By the strain exerted by the hand upon the parts in
rolling them up, an intimate contact between the writing or delineation and the
copying book sheet is produced, giving the required pressure. To avoid unequal
winding and consequently unequal pressure care must be taken that the resisting
point (the hook or projection) shall be exactly between the knots d'
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:-
1. In a copying apparatus, in which the copying book is pressed by means of a
stretched cloth rolled up together with the said book, the arrangement of a lath
at the top and bottom of said cloth, and of a string d, the ends of which are con-
nected with the ends of one of the two laths for the purpose of suspension to a
hook or other projection when pressing the copying book; the arrangement includes
two knots d' made near the middle of said string to prevent the string shifting

and described.
2. The improved copying apparatus substantially as herein shown and described.
Dated this 6th day of April 1892.
