PROVISIONAL SPECIFICATION.
An Improvement in Machines for Printing on Book Edges.
I, NEIL MACPHAIL, of 11, Bothwell Street, in the County of the City of Glasgow,
North Britain, Engraver, do hereby declare the nature of this invention
to be as follows:
This invention relates to an improvement in machines for printing on book
edges.
In carrying out my invention I construct a platen printing machine, substitut-
ing for the ordinary flat platen on which the sheet of paper is laid to be printed,
two moveable jaws or clamps. These moveable sliding jaws or clamps are made
of a depth to receive and hold the books to be operated upon and can be adjusted
to suit their varying thicknesses.
On the books being placed between the jaws of the clamp, a screw or other
suitable device, acting on one or both of the jaws of the clamps causes it or them
to compress the book to the extent that will enable it to receive on the edges of
the leaves a clear and perfect impression from the type or block.
A reversal of the screw or other device relieves the books after receiving the
impression.
The degree of impression can be regulated by a lever or other convenient means
under immediate control of the printer.

An Improvement in Machines for Printing on Book Edges.
I, NEIL MACPHAIL, of 11, Bothwell Street, in the County of the City of Glasgow,
North Britain, Engraver, 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 an improvement in machines for printing on book
edges.
In carrying out my invention I construct a platen printing machine, substitut-
ing for the ordinary flat platen on which the sheet of paper is laid to be printed,
two moveable jaws or clamps. These moveable sliding jaws or clamps are made
of a depth to receive and hold the books to be operated upon and can be adjusted
to suit their varying thicknesses.

page_text: On the books being placed between the jaws of the clamp, a screw or other
suitable device, acting on one or both of the jaws of the clamps, causes it or them
to compress the book to the extent that will enable it to receive on the edges of
the leaves a clear and perfect impression from the type or block.
A reversal of the screw or other device relieves the books after receiving the
impression.
The degree of impression can be regulated by a lever or other convenient means
under immediate control of the printer.
In order that my invention may be properly understood and readily carried into
effect I have appended one sheet of drawings, of which,
Figure 1 is a side elevation and detached view of the bracket or platen attach-
ment, shown in the horizontal position of a printing machine embodying my
invention.
Figure 2 is a plan of the same, and
Figure 3 is a perspective view of a part printing machine with my improved
bracket or platen attachment applied thereto.
A is a sole plate of the platen, which receives its motion from a transverse
shaft, and is brought up to the type alter the manner of printing machines more
or less of that class. Fitted to the said sole plate A are two jaws B and C. The
jaw B is preferably stationary but is made adjustable and is capable of being
clamped into any desired position by the bolts D and E. The under surface of
the flange or bearing surface b of the said jaw B is provided with two longitudinal
projections, which engage with the grooves I and G so that it may move in the
same plane horizontally. The jaw is slidably adjustable by means of a longi-
tudinal screw H passing through a fixed arm I, which acts as a nut for the lateral
movement of the said slidable jaw C. The screw is operated by the bent handles J.
To allow of the due movement of the jaw C relatively with that of the fixed jaw B
the two bolts K and L are made to work in the grooves F and G aforesaid.
The books (the edges of which are to be printed upon) are fed between the
two jaws B and C, along the transverse path M and are delivered at the opposite
end M', shown in dotted line, Figure 2.
A spring stop or catch N, one end of which projects between the jaws, per-
forms the function of a stop and so ensures the true position the book is to occupy,
while being printed upon and suitable distance pieces c will be employed to fill
up the spaces when shallow material is being printed upon, as will be understood
from Figures 1 and 2.
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:―
The improvements in machines for printing on book edges, substantially as
described and illustrated on the sheet of drawings.
