Improvements in the Production of Drawings, Designs, and the like
on Transfer Paper and in Apparatus therefor.
I, GUSTAV HENRY BLOCK, of 9, May Street, Beverley Road, Hull in the County
of York, Lithographer, do hereby declare the nature of this invention to be as
follows:
This invention relates to improvements in the production of drawings, designs
and the like on transfer paper and in apparatus therefor.
According to my invention I stretch the transfer paper, which is preferably
highly glazed and on which the drawing is to be made in a frame constructed as
hereinafter described, and I hinge this frame to a base plate provided with a block
upon which a relief plate such as an etched metal plate rests the said frame being
so hinged that when it is lying upon the base plate the stretched transfer paper
lies over the upper surface of the plate on the block in such a manner that a
shading effect can be produced on the transfer paper by means of a crayon as
hereinafter more particularly described.
the
In carrying out my invention I provide a frame formed of two parts namely-a
bottom half which is hinged along one side to the base plate and is grooved upon
its upper surface and .an upper half grooved upon its under surface
the said grooves being made SO as to correspond in position with
grooves in the upper surface of the lower half of the frame and being fitted with
a suitable packing such as india-rubber. Suitable clamps are provided in con-
nection with the two halves whereby they can be firmly and expeditiously fastened
together. In practice I advantageously employ clamps consisting of metal plates,
hinged to the upper half frame and adapted to be sprung into recesses in the lower
half of the said frame.
The base plate of the apparatus is provided with an upwardly projecting rim
upon which a hand rest for the artist can be supported.
To stretch the transfer paper in the frame the upper half of the latter is removed
and the lower half is laid down upon the base plate to which it is hinged.
Transfer paper is then laid upon the block which, as hereinbefore described, is
secured to the base plate and passes up through the frame and the upper half of
the frame is then placed in position over the lower half of the frame and clamped
to the same. By this means the edges of the paper are clamped between the upper
face of the lower half of the frame and the under surface of the upper half of the
frame, the india-rubber packing forcing the said paper into the grooves in the
lower half of the frame.
The apparatus is employed as follows:-
The sheet of transfer paper being stretched upon the frame in the manner
herein before described the drawing to be traced is then outlined upon the same in
the ordinary manner. The frame is then lifted up upon its hinges and the required
zinc plate or stipple medium is then laid upon the upper face of the block and the
frame again lowered upon the base plate.
The shading of the outlined drawings is then effected by means of ordinary
lithographic crayons and the stipple medium then replaced by another to produce
a different effect and so on as required. The drawing thus produced upon the
transfer paper is then transferred to a stone or plate in the usual manner.
The stipple mediums which I preferably employ consist of etched plates of

page_text: different patterns or designs so that by suitably choosing the stipple mediums I
can produce any desired shading effect.
It will be obvious that with my apparatus drawings, designs and the like can be
produced with much greater facility and at considerably less cost than with
apparatus as heretofore usually employed.

Improvements in the Production of Drawings, Designs, and the like
on Transfer Paper and in Apparatus therefor.
I, GUSTAV HENRY BLOCK, of 9, May Street, Beverley Road, Hull in the County
of York, Lithographer, 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 relates to improvements in the production of drawings, designs
and the like on transfer paper and in apparatus therefor.
According to my invention I stretch the transfer paper, which is preferably
thin and highly glazed and on which the drawing is to be made, in a frame con-
structed as hereinafter described, and I hinge this frame to a base plate provided
with a block upon which a relief plate such as an etched metal plate rests the said
frame being so hinged that when it is lying upon the base plate the stretched
transfer paper lies over the upper surface of the plate on the block in such a
manner that a shading effect can be produced on the transfer paper by means of a
lithographic chalk or crayon as hereinafter more particularly described.
In carrying out my invention I provide a frame formed of two parts namely--a
bottom half which is hinged along one side to the base plate and is grooved upon
its upper surface and an upper half grooved upon its under surface, the said grooves
being made so as to correspond in position with the groove in the upper surface
of the lower half of the frame and being fitted with a suitable packing such as
india-rubber. Suitable clamps are provided in connection with the two halves
whereby they can be firmly and expeditiously fastened together. In practice I
advantageously employ clamps consisting of metal plates, hinged to the upper half
frame and adapted to be sprung into recesses in the lower half of the said frame.
The base plate of the apparatus provided with an upwardly projecting rim.
upon which a hand rest for the artist can be supported.
In the accompanying drawing,
Figure 1 is a plan of apparatus constructed according to my invention;
Figure 2 is a vertical section on the line 2-2 of Figure 1;
Figure 3 is a section of the upper half of the frame; and
Figure 4 is a similar section of the lower half of the said frame.
a is a base plate, and a¹ the upwardly projecting rim formed around the
periphery of the same and upon which a suitable hand rest for the artist is placed
when a drawing is to be made. b is the block upon which the relief plate of a
stipple or line medium rests the said block being formed, as clearly shewn in
Figure 2, rigid or continuous with the base plate a.
c is the bottom or lower half of my frame which, as clearly shewn in the drawing,
fits around the block b the said bottom half c being hinged at c¹, c¹.to the base
plate a so that the whole frame can be raised from the block as shewn in dotted

page_text: lines in Figure 2. c is the groove running around the upper surface of the said
bottom half c of the frame.
d is the upper half of the frame which can be wholly detached from the bottom.
half c and d is the groove running around the under surface of the same, the
said groove being so arranged that, when the upper half frame d is placed in
position upon the lower half c, the groove d' comes opposite the groove &. d² is
the rubber or other packing fitted in the groove d' for securing the paper in
position as hereinafter described. d³, d³ are metal clamps hinged, as shewn, to the
top of the upper half d of the frame and bent inwards at their lower ends the said
lower ends being designed to be snapped into the recesses ³, 3 in the lower half c
of the frame, as shewn in Figure 2, so as to secure the two halves of the frame
together. e is the sheet of transfer paper and f the etched plate or stipple medium.
To stretch the transfer paper e in the frame c, d the upper half d of the latter is
removed and the lower half c is laid down upon the base plate a to which it is
hinged. Transfer paper e is then laid upon the block 6 which, as herein before
described, is secured to the base plate a and passes up through the frame and the
upper half d of the frame is then placed in position over the lower half of the frame
and clamped to the same. By this means the edges of the paper are clamped
between the upper face of the lower half c of the frame and the under surface of
the upper half of the frame, the india-rubber packing 2 forcing the said paper c
into the groove 2 in the lower half c of the frame as shewn in Figure 2.
The apparatus is employed as follows:-
C,
The sheet of transfer paper e being stretched upon the frame d in the manner
herein before described the drawing to be traced is then outlined upon the same in
the ordinary manner. The frame c, d is then lifted up upon its hinges c', c¹ and
the required relief plate is then laid upon the upper face of the block b and the
frame again lowered upon the base plate.
The stipple or line mediums which I preferably employ consists of etched plates
with ordinary lithographic crayons and the relief plate f replaced by another
to produce a different shading effect and so on as required. The drawing thus
produced upon the transfer paper e is then transferred to a stone or plate in the
usual manner.
The stipple or line mediums which I preferably employ consist of etched lates
of different patterns or designs so that by suitably choosing the stipple or line
mediums I can produce any desired shading effect.
It will be obvious that with my apparatus drawings, designs and the like can be
produced with much greater facility and at considerably less cost than with
apparatus as heretofore usually employed.
My process is of great value for colour work as the outline or offset can be made
on the back of the transfer paper which will enable the artist to work more easily
with his chalk. Offsets usually made with a fatty ink and dusting powders are
rendered harmless when made, as above described on the back of the transfer
paper.
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. The described process for producing drawings, designs and the like on transfer
paper, such method consisting of stretching the paper in a frame, outlining the
drawing on the stretched paper and then producing the required shading effects
by means of etched plates of stipple or line mediums placed under the stretched
paper, substantially as described.
2. In a process of the kind described in Claim 1 outlining the drawing upon the
back of the transfer paper to avoid any injurious effect, substantially as, and for
the
purpose, described.
3. A device for carrying out the process described in Claim 1 such device con-
sisting of a frame made in two parts and hinged to a base plate in such a manner

page_text: that the paper can be stretched over the opening in the frame by being clamped
between the two halves of the frame which can then be lowered or raised from a
block serving as a support for the stipple or line medium by lowering or raising the
frame, substantially as described.
4. In a process of the kind described in Claim 1 the employment of apparatus
consisting of the base plate a block b frame c, d hinged to the base plate a and
provided with clamps d³ for locking the two parts c and d of the frame together,
and with grooves c³, and packing & for securely holding the paper in the frame.
