IWALTER EDMUND KERSLAKE Mechanical Engineer of 41 High Street Wavertree
Liverpool in the County of Lancaster, do hereby declare the nature of this invention
to be as follows:-
The object is to provide a simple light durable and compact press mainly applicable
for copying letters.
The invention consists in the combination of two headstocks connected by telescopic
or hinged ties and having a roller or pressure piece in fixed bearings and a roller
or pressure piece in movable bearings held in position by springs. Lever wedge or
quivalent apparatus is provided for separating the rollers when desired.

COMPLETE SPECIFICATION.
Improvements in Presses.
I WALTER EDMUND KERSLAKE Mechanical Engineer, of 41 High Street Waver-
tree, Liverpool, in the County of Lancaster, 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 is to provide a simple light durable and compact press mainly applicable
for copying letters."
The invention consists essentially in the combination of two headstocks connected
by telescopic or hinged dies and having a roller or pressure piece in fixed
bearings and a roller or pressure piece in movable bearings held in position by
springs. Lever wedge or equivalent apparatus is provided for seperating the rollers
when desired.

DESCRIPTION OF THE DRAWINGS.
Fig. 1 is a plan, and fig. 2 a side elevation of a press constructed in accordance
with my invention. A are headstocks connected by binged ties B which allow of the
headstocks being brought close together, as shown by the dotted lines. Instead of
using hinged ties the headstocks may be connected by telescopic tubes. The head-
stocks are made with a flat base to rest on a table and with snugs C to rest against
the edge of the table to prevent the press from slipping when a book or object is being
pushed through between the rollers or pressure pieces. d are brackets fixed to the
headstocks by thumb-screws and nuts e, and retained in position by pins f secured to
the said headstocks and passing through holes in the brackets d.

in slots in the said arms and be held in position by springs in any usual way but not
so advantageously. The arms are made with three sets of bearings to allow of the
position of the upper roller being adjusted for the purpose above set forth. Quite
sufficient adjustment may be obtained by regulating the position of the upper or lower
roller and in practice only one of the rollers would be provided with means for
adjustment. are levers hinged to the headstocks at m, and provided with lifting

rollers nearly equal to that of the book or object being pressed. When it is desired
to stow the press the rollers are taken out of their bearings, the headstocks are
brought close together as shown by the dotted lines, and the rollers are placed
transversely between them.
Fig. 3 is an elevation showing a modified construction of adjustable lower bearings,
here the brackets fit in vee shaped recesses.
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 :-
First. Presses constructed substantially as herein set forth.
Second. Presses with headstocks united by telescopic or equivalent connections
substantially in the manner and for the purpose set forth.
Third. Presses with rollers in adjustable bearings substantially in the manner and
for the purpose set forth.
