I, ARTHUR PAGET, Mechanical Engineer. of Loughborough in the county of
Leicester, do hereby declare the nature of my invention for IMPROVEMENTS IN
APPARATUS FOR OBTAINING MULTIPLE COPIES OF WRITING AND DESIGNS, to be as
follows:
This invention has for its object improvements in apparatus used for obtaining
multiple copies of writings and designs. The first part of my invention consists in
constructing the inking-slab with an air-tight-cover which may also enclose the
inking-roller and by this means the ink on the inking-slab and roller is prevented
from becoming dry and hard and is kept in the properly viscid condition ready for
use and thus the ink need not be "cleaned-off" after using the apparatus and the
slab and roller do not require to be re-inked each time they are used as is ordinarily
the case.
"
The second part of my invention consists in making the top-surface of the inking-
slab of an elastic material such as is used for the "inking-rollers in printing-
machines or any such similar suitable material. This causes the ink to be more
evenly spread on the inking-roller and will be found to keep the ink in a much
more useable condition than the slabs hitherto used. The elastic top-surface may
be also used for making an air tight-joint between the inking-slab and its cover.
The third part of my invention consists in the manufacture and use of spring-
stops or hinged-stops to assist in placing the sheets of paper to be printed upon in
the proper position for printing upon them, such stops being so constructed as to
be put out of the way (so as not to injure the Stencil) by the Stencil-frame as it is
closed down.

I, ARTHUR PAGET, Mechanical Engineer of Loughborough in the County of
Leicester, do hereby declare the nature of my invention for IMPROVEMENTS IN
APPARATUS FOR OBTAINING MULTIPLE COPIES OF WRITINGS AND DESIGNS and in
what manner the same is to bo performed, to be particularly described and
ascertained in and by the following statement:-
This invention has for its object improvements in apparatus used for obtaining
multiple copies of writings and designs.
"
The first part which I will describe relates to a methord of constructing the
"Inking-slab" with an air-tight cover, which may also enclose the Inking-roller,"
and by this means the ink on the "inking-slab" and roller is prevented from
becoming dry and hard, and is kept in the properly viscid condition ready for use,
and thus the ink need not be "cleaned off" after using the apparatus, and the slab
and roller do not require to be re-inked each time they are used as is ordinarily
the case.
Fig. 1. 2. 3&4 (sheet I) show this arrangement, Fig. 1 being a longitudinal
section through the "inking-slab" and cover. Fig. 2 a cross section of same.
Fig. 3. a plan of the "inking-slab" with the cover removed, and Fig. 4 an enlarged
section of the edge of the cover and slab.
The "inking-slab" A Figs. 1. 2. 3 & 4, may be of wood, zinc, or other suitable
material, Round this I form a groove A¹ which I fill with an elastic material,
such as is used for the inking-rollers in printing machines, or any such similar
suitable material,. The lid A2 Figs. 1. 2 & 4, I form with an edge, or rim A³,
Fig. 4 shaped in such a manner that there shall be a narrow bearing-strip A4,
Fig. 4, to rest upon the elastic material which fills the groove A¹. The lid A2,
I fasten to the slab A, with a strap A5, or other suitable fastening, The bearing-
strip A being thus kept pressed down by the elastic pressure of the strap upon the
elastic material in the groove A¹, a perfectly air-tight joint is thereby made.
I prefer to enclose the inking-roller within this air-tight cover, by making a
suitable recess in the slab, as shown at A6, Figa 1. 2 & 3, the position of the roller
being shown in dotted lines in Fig. I.
The second part which I will describe consists in making the top surface of the
"inking-slab of an elastic material, such as is used for the inking-rollers in
printing machines, or any such similar suitable material. This causes the ink to be
more evenly spread on the inking-roller and will be found to keep the ink in a
much more usable condition than the slabs hitherto used. The elastic top-surface
may be also used for making an air-tight joint between the "inking-slab" and
its cover.
"
The arrangement will be readily understood by refering to Figs. 5. 6. 7 & 8
(sheet 1) where Fig. 5 is a longitudinal section through such an inking-slab" and
Fig. 6 is a cross section of the same, Fig. 7 is a plan of the "inking-slab"
cover.

page_text: with the cover removed; and Fig. 8. is an enlarged section of the edge of the cover
and slab.
:
The "inking-slab" B Figs. 5.7 & 8 is shown coated with a layer B1 of the
elastic material above refered to. The air-tight cover B I construct with an edge,
or rim, Bs Fig. 8 shaped in such a manner as to leave a narrow bearing-strip B* to
rest upon the edge of the elastic surface B' all round. The lid B3 I fasten on with
a strap B, or other suitable fastening. The bearing-strip B being thus kept
pressed down upon the elastic covering of the slab, by the elastic pressure of the
strap B, a perfectly air-tight joint is thereby made.
"
I prefer to enclose the "inking-roller" within this air-tight cover, by making a
suitable recess in the slab as shown at B° Figs. 5. 6 & 7, the position of the roller
being shown by dotted lines in Fig. 5.
It will be seen, that by this arrangement, I obtain an air-tight cover, both for
the "inking-slab" and inking-roller, with a smooth elastic surface to the "inking-
slab," this enables the ink to be more evenly sprend on the inking-roller, and will
be found to keep the ink in a much more usable condition than the slabs hitherto
used, for apparatus for obtaining multiple copies of writings and designs. Thus,
the slab and roller are kept always properly inked and ready for immediate usc
whenever required, and do not require to be cleaned after using, which is a dirty
and troublesome, but necessary process in other arrangements of "inking-slabs,"
and necessitates a serious waste of ink which is obviated by my improvements.
The third part which I will describe consists in the manufacture and use of
"spring-stops," or "hinged-stops," to assist in placing the sheets of paper to be
printed upon, in the proper position for printing upon them, such stops being so
constructed as to be put out of the way (so as not to injure the "stencil") by the
stencil-frame as it is closed down.
This arrangement is shown in Figs. 9. 10. 11 & 12 (sheet 2). Fig. 9 being a
perspective view of a printing-frame with the stencil-frame lifted. Fig. 10 being
a perspective view of the opposite corner, with the stencil-frame removed from its
hinges, so as to leave the "spring-stops" exposed, Fig. 11 is an end view, the
stencil-frame being shown by dotted lines in the act of closing and commencing to
pull down the "spring-stops." Fig. 12, is a similar view showing the "spring-
stops" pulled down into the position occupied when the frame is closed.
C, is the writing and printing-slab, Figs. 9. 10. 11 & 12 (sheet 2) C¹, the stencil-
frame C, the corner "spring-stop," C³, the side "spring-stop."
It will be seen that the corner "spring-stop" C2, is fixed at the points C; C',
(Fig. 10) but works freely upwards and downwards in the eye C³ so that by
pressing the projecting end C downwards, the "spring-stop" C2 takes the position
shown in Fig. 12. Similarly, the "Spring-stop " C3, is fixed at the points C7, 07,
(Fig. 10) but works freely upwards and downwards in the eye C³ so that by
pressing the projecting end C downwards, the "spring-stop" C³ takes the position
shown in Fig. 12.
Thus it will be seen, that the projecting ends C6, C, of the "spring-stops" C³, C³,
(Fig. 10) are caught by the edges C10, C11, of the stencil-frame C, Fig. 9. as it closes,
and are thereby carried down below the surface of the writing and printing-slab C,
as shown in Fig. 12. and thus do not injure the stencil C, (Fig. 9), and directly
the stencil-frame is again lifted, the "spring-stons" rise into the position shown in
Figs. 9. 10 & 11, ready for use, as corner and side guides, in placing sheets of paper
upon the writing and printing-slab for the purpose of printing thereon.
It will be obvious that these "stops" may, if desired, be hinged, at either of the
points C, C, and C, C', Fig. 10. in which case they would require an independent
spring, or other suitable arrangement, for lifting them.
"
From the foregoing description it will be seen, that, these "spring-stops," or
hinged-stops," greatly facilitate the speedy productions of accurately printed
copies and they give a correct register" and so enable the operator to make the
whole number of copies, which the stencil will produce, with the headings & in
exactly the same place upon every sheet of paper.

page_text: Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I desire it to be
understood that I do not confine myself to the exact details herein set forth, as
such may be varied, or modified, without departing from the principle thereof; but
what I claim as my improvements in apparatus for obtaining multiple copies of
writings and designs are
(1.) The method of constructing the " inking-slab" with an air-tight cover,
which may also enclose the inking-roller, and by this means the ink on the
"inking-slab" and roller is prevented from becoming dry and hard and is kept in
the properly viscid condition ready for use, substantially as herein described with
reference to Figs. 1. 2. 3 & 4. (sheet I).
(2.) Making the top surface of the "inking-slab" of an elastic material such as
is used for the inking-rollers in printing machines, or any such similar suitable
material, substantially as herein described with reference to Figs. 5. 6. 7 & 8.
(sheet I).
"
(3.) The manufacture and use of "spring-stops," or hinged-stops" to assist in
placing the sheets of paper, to be printed upon, in the proper position for printing
'upon them, such " stops" being so constructed as to be put out of the way (so as
.not to injure the stencil) by the stencil-frame as it is closed down, substantially as
herein described with reference to Figs. 9. 10. 11. & 12. (sheet 2).
