Complete Specification Left, 30th Dec., 1896-Accepted, 20th Feb., 1897
I, ISING RHEINBERG, of 32 Snow Hill, London, E.C., Commercial Agent, do hereby
declare the nature of this invention to be as follows:-
This invention relates to portable copying presses, and consists in an improved
form of construction, whereby, whilst the apparatus is eminently light and portable,
the user is enabled to introduce the copying book into the pressing rollers with
ease, and thereafter to apply easily, such as by a single turn of the hand, the
requisite pressure for efficient copying, and to traverse the copying book through
the apparatus with ease, by the turning of a small handle, whilst the press is held upon
the knees, or in like position, where it would be impossible to use the heavy screw-
down desk copying presses.
To carry my invention into effect by way of example 1 may employ small steel or
metal rods or rollers, as my pressing devices, one or more of which are fixed free
to rotate in the same direction, and parallel to one another, in suitable bearings in
frames, or on a small base plate of wood or similarly light material. Upon these
the copying book travels, and the necessary pressure is produced by a third light
steel rod or roller, mounted, free to rotate, in a pivotted upper frame. The said
frame is pivotted about one of the lower rods or rollers, and thus when lifted, the
upper rod or roller lifts away from the other lower rod or roller, to admit easy
insertion of the copying book.
The upper pivotted frame and roller is then closed down upon the entering edge
of the book, and is held in position firmly by any suitable pressing device, such as
a pivotted stirrup bar of steel, extending the full width of the book, so as to allow
the book to travel through the stirrup, the latter being pressed over a detent such
as a cam fixed on a small bar traversing the base plate at right angles to the pressing
rollers.
The further necessary pressure is then brought upon the upper pivotted frame
and roller, by the rotation of the said cam shaft and cam detent on the spring steel
stirrup, by means of a handle fixed to said shaft; or by a key or wrench, provided
with the press; or the extra pressure may be produced by a set screw, or other
suitable means.
I find it advantageous for the proper travel of the copying book through the press,
that all the rollers above and below the book should rotate, to feed the book through,
at the same speed of periphery, and in the reverse direction of rotation, as regards
the lower and upper rollers.
This I effect by gearing the two lower rollers to one another on one side, by a
gearing of three uniform spur wheels, and upon the other side, I gear the first motion
lower roller to the upper roller at the end of the pivotted frame, by two equal and
uniform spur wheels.
As the first motion driving roller is that one situated as the hinge of the pivotted
frame, it is obvious that the pivotted frame, and the geared upper roller at its end,
can be lifted to admit and withdraw the copying book, whilst the upper roller still
remains in proper gear with the first motion driving roller at its pivot.
The proper speed also of the upper roller is maintained exact, whatever may be

page_text: the thickness of the copying book employed, as the gearing operates in its proper
ratio upon all the rollers, whatever the angle of the pivotted frame.

1 ISING RHEINBERG of 32 Snow Hill London E.C. Commercial Agent, 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 portable copying presses and consists in an improved
form of construction, whereby, whilst the apparatus is eminently light and portable,
the user is enabled to introduce the copying book into the pressing rollers with
ease, and thereafter to apply easily, such as by a single turn of the hand, the requisite
pressure for efficient copying, and to traverse the copying book through the apparatus
with ease by the turning of a small handle, whilst the press is held upon the knees
or in like position, where it would be impossible to use the heavy screw-down
copying presses.
To carry my invention into effect by way of example, I may employ small steel or
metal rods, or rollers as my pressing devices, one or more of which are fixed free to
rotate in the same direction, and parallel to one another in suitable bearings in
frames, or on a small base plate of wood or similarly light material. Upon these, the
copying book travels, and the necessary pressure is produced by a third light steel
rod or roller, mounted free to rotate in a pivotted upper frame. The said frame is
pivotted about one of the lower rods or rollers, and thus, when lifted, the upper rod
or roller lifts away from the other lower rod or roller, to admit easy insertion of the
desk copying book.
The upper pivotted frame or roller is then closed down upon the entering edge
of the book, and is held in position firmly by any suitable pressing device, such as a
pivotted stirrup bar of steel extending the full width of the book, so as to allow the
book to travel through the stirrup, the latter being pressed over a detent, such as
a cam, fixed on a small bar, traversing the base plate at right angles to the pressing
rollers.
The further necessary pressure is then brought upon the upper pivotted frame and
roller by the rotation of the said cam shaft, and cam detent, on the spring steel
stirrup, by means of a handle fixed to said shaft, or by a key or wrench provided
with the press; or the extra pressure may be produced by a screw or other suitable
means.
I find it advantageous for the proper travel of the copying book through the
press, that all the rollers above and below the book should rotate, to feed the book
through, at the same speed of periphery, and in the reverse direction of rotation, as
regards the upper & lower rollers.
This I effect by gearing the two lower rollers to one another on one side by a
gearing of three uniform spur wheels, and upon the other side I gear the first motion
lower roller to the upper roller at the end of the pivotted frame, by two equal and
uniform spur wheels.
As the first motion driving roller is that one situated as the hinge of the pivotted
frame, it is obvious that the pivotted frame and the geared upper roller at its end can
be lifted to admit and withdraw the copying book, whilst the upper roller still
remains in proper gear with the first motion driving roller at its pivot.

page_text: the thickness of the copying book employed, as the gearing operates in its proper
ratio upon all the rollers whatever the angle of the pivotted frame.
And in order that my invention may be the better understool, I now proceed to
describe the same in relation to the drawings hereto annexed, and to the letters and
figures marked thereon.
Fig. 1 is a front elevation of my portable copying press, open, with the book just
entered.
Fig. 2 is a tranverse section through the same with the book gripped in the
pressing
rollers.
Fig. 3 is a plan of the same.
A is a base plate, conveniently of a light stamped metal, such as steel, and upon
this are mounted two vertical standards B, B, carrying in bearings the first motion
shaft C and a countershaft D.
The first motion shaft C is provided with a handle E by which the press is operated
and the copying book forced through the rolls.
The spindle C forms the first under roller, and it is geared by equal gearing a a,
with an idle wheel a' between, to the second under roller or countershaft D which
thus is caused to revolve in the same direction and at the same speed as C.
The first motion shaft C carries also a cog wheel gearing into a cog wheel of
the same size b¹ so as to produce the same speed of rotation as that of the lower
roller D, but in an opposite direction, upon an over-roller or spindle F, mounted on
a pair of arms GG pivotted on the spindle and of which the ends are connected
by a pivotted stirrup bar H, which is raised as in Fig. 1 to lift the top roller F,
without disengagement of the driving gear bbl of the said roller, to admit the
copying book between the rollers F and D the book lying upon the two lower
rollers CD as a travelling table.
When the book is in place, the roller F is brought down upon the book, and is
pressed thereon by bringing the stirrup bar H under the cam K pivotting round a
pink fixed to the front of the bed plate or to a bracket thereon. When the stirrup
har has been brought under the face of the cam K of smallest radius, with the
lever L (which is a prolongation of the said cam) extending to the left as in Fig. 1,
the lever L is brought round to the right, carrying the cam with it, and thus
forcing down the stirrup bar H by the increasing radius of the cam, so as to
produce any desired pressure by the top roller upon the copying book.
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
1st. A portable roller copying press adapted to receive a copying book of variable
thickness, by the lifting of the upper pressing roll or rolls, without disengagement
of the said upper roll or rolls from its rotating gearing, to grip the said book with
a suitable copying pressure by suitable pressure devices, and to cause the said book
to travel through upper and lower pressing rolls by the operation of a crank handle.
2nd. In a portable roller copying press an upper pressing roll, mounted upon a
pivotable lever, to admit the lifting and lowering of the said upper roller, whilst still
remaining engaged with the driving gearing, substantially as described.
3rd. In a portable roller copying press the engagement of the two lower pressing
rolls to a first motion shaft by three equal geared wheels, and the simultaneous
engagement of the first motion shaft with an upper pressing roll mounted upon a
frame pivotable about the said first motion shaft, by a pair of equal geared wheels
to ensure the rotation of the upper and lower pressing rolls at the same speed but in
opposite directions of rotation substantially as described.
4th. In a portable roller copying press the arrangement of the pressing mechanism,
consisting of a cam provided with a hand lever, and rotating round a fixed pivot,
producing the required pressure upon the centre of an elastic bar, connecting the
ends of the pivotable arms carrying the upper roll or rolls, substantially as described.

page_text: 5th. The arrangement and combination of parts forming a portable roller copying
press, substantially as described herein, and as illustrated in the drawings annexed
hereto.
