PROVISIONAL SPECIFICATION.
Improvements in Apparatus for Copying Letters and other
Documents.
I ABRAM CHARLES HERTS of 5 Ridgmount Street Bloomsbury Manufacturer, do
Hereby declare the nature of this invention to be as follows:-
The object of this invention is to enable a person to readily take one or more
copies of one or more letters or other documents by means of a simple portable
inexpensive copying apparatus thus dispensing with the ordinary copying press
and stand thus affording increased convenience at a considerably reduced cost.
This I effect by making a copying pad consisting of a back of rubber cloth or
other equivalent material on which a pad of blotting paper or other suitable
absorbent substance is mounted and covered with a linen face-Over this face an
ordinary oil copying mat corresponding in size with the copying pad is laid and on
the top of such oil mat a rubber sheet is placed.
Such copying pad mat and rubber sheet together constitute my improved copying
apparatus.
'
The operation of my invention is as follows: To take one or more press copies take
one or more tissues and place the copying pad beneath them then damp them with an
ordinary copying brush or roller and place the oil mat on the top and allow them to
remain until required for use-The copying pad absorbes the moisture and so keeps
the tissues damp while the oil mat prevents the moisture evaporating therefrom-
When ready to take the press copy or copies remove the oil mat and substitute
therefor the document or documents to be copied over which then place the rubber
sheet. Then pass the hand over the back of such rubber sheet or instead of using
the hand employ a suitable rubber-after which remove the rubber sheet and
document or documents when it will be found that a perfect copy or copies has or
have been obtained.

Improvements in Apparatus for Copying Letters and other
Documents.
I ABRAM CHARLES HERTS of No. 5 Ridgmount Street Bloomsbury London, Manu-
facturer, 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 object of this invention is to enable a person to readily take one or more
copies of one or more letters or other documents by means of a simple portable
inexpensive copying apparatus thus dispensing with the ordinary copying press and
stand and affording increased convenience at a considerably reduced cost.
This I effect by making a copying pad consisting of a back of rubber cloth or other
equivalent material on which a pad of blotting paper or other suitable absorbent sub-
stance is mounted and covered with linen or cotton face-Over this face an ordinary oil
copying mat corresponding in size with the pad is laid and on the top of such oil
mat a sheet of rubber gutta percha or other suitable material is placed.
Such copying pad mat and rubber sheet together constitute my improved
copying apparatus.
The operation of my invention is as follows:-To take one or more press copies
first damp the pad then place thereon one or more tissues and cover them with the
oil mat The tissues absorb the moisture and are kept damp and ready for immediate
use as the oil mat prevents the moisture evaporating therefrom. When ready to
take the press copy or copies remove the oil mat and substitute therefor the docu-
ment to be copied and place the rubber sheet over it-Then pass the hand over the
back of such rubber sheet or instead of using the hand employ a wooden block or
rubber after which remove both the rubber sheet and the document when it will be
found that a perfect copy has been obtained.
Having now particularly described and ascertained the nature of my said invention
and in what manner the same is to be performed I declare that what I claim is
1. A copying pad consisting of a back of rubber cloth or other equivalent material
whereon an absorbent blotting pad having a linen or cotton face is mounted all
substantially as hereinbefore described.
2. The use in conjunction with such copying pad of an oil mat and rubber sheet
in the manner herein before described.
3. The improved combination copying apparatus all substantially as hereinbefore
described.
