page_text: I, HENRY HARRIS LAKE, of the firm of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings in the County of Middlesex 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 comprises improvements in the copying press described in the speci-
fication of Letters Patent of the United States of America dated October 13th, 1885,
and numbered 328,039.
In the accompanying drawing, in which similar letters of reference indicate like
parts,
Figure 1 is a perspective view of the improved copying press with the platen
dropped and a book upon it.
Figure 2 is a side elevation with the platen partly down.
Figure 3 is a rear elevation.
Figure 4 is an enlarged detail described below.
Figure 5 is a vertical section on line xx figure 2.
A represents the bed of the press adapted to be attached to a wall or other vertical
support. This bed is provided with a hinged cover or lid B pivotted at B' to the
same at such a point that it can remain in a vertical position when desired. This

cover hides when closed, two compartments, the compartment C in which hangs the
brush D suspended from the hook. b secured to the under side of the cover, and the
compartment E in which is supported the water receptacle or pan F whose flanges F¹
rest on the upper edges of said compartment. The press is preferably made open
behind to save weight. When the lid is closed the water and brush are out of sight
but are of course easily accessible while the brush is kept from getting out of shape,
as is the case when it rests in the pan.
H is the platen pivotted to the bed by means of the sliding hinges H¹ not new in this
invention. For the purpose of preventing the book J which is operated upon from
resting directly upon the hinges we provide the steps or shelves I, which project
inwardly from the lower portion of the rear or inner side of the platen and support
and protect the copy-book J, and also serve as levers to keep the platen from working
back too close to the bed. Levers K K are eccentrically pivotted at K' to discs Lon
opposite sides of the bed, and are at their outer ends provided with the cross-bar K"
which serves as a handle to operate the press and also in connection with the pins N
as a rest or support for the platen when it is in a horizontal position, substantially as
shown in the Letters Patent above referred to. The discs L are centrally pivotted
to the shaft L' supported by the bed and are each provided for a portion of their cir-
cumference, with teeth L", see figure 2. These teeth are adapted to be engaged by a
locking device 0 meshing into the same and adapted to slide vertically in the
cross-bar P interiorly grooved for the purpose, and to be raised and lowered by means
of the cam R pivotted at R¹ to the bed and operated by its lever R". S S are hooks
pivotally applied to the inner. sides of the levers K, see figures 4 and 5, resting on
pins S¹ extending from said levers, prevented by means of the projections S" which
strike said pins from lifting too high relatively to said levers K, and by the pins T
projecting from the bed from being lifted too high actually. These pressure hooks S
engage lugs U on the platen.
The operation is briefly as follows: the platen being thrown down as in figure 1 sup-
ported by the crossbar K" and pins N, the book is laid upon it, and the platen raised
until the book touches the bed, resting meantime on the steps I, the pressure hooks S
drop upon the lug U, and the cross-piece K" is depressed, thus by means of the
eccentrically pivotted levers K, giving great pressure upon the book. To release the
book, the cross-piece or handle is raised causing the pins S¹ to lift the pressure arms
and release the platen which may then be swung down into a horizontal position. By
means of the pins S¹ on the levers K and the pins T on the bed, the hooks S prevent
the arms K from being raised above the substantially horizontal position shown in
figure 2 and thus prevent the platen H from dropping inside the cross bar K" into a
vertical position. When the same book, or books of the same thickness only are used,
the lock O is kept constantly engaged and the cam-lever R" is always in the position
shown in figures 2, 3, and 5. But if books of different thicknesses are to be used,
the lock O is depressed by raising the cam lever into a horizontal position, thus
moving the hook (which with the lever K is eccentrically pivotted to the disc) until
it projects the proper distance to accommodate the book desired to be used. This can
readily be ascertained by placing the book or books in the platen and pressing them
against the bed.
Having now particularly described and ascertained the nature of the said invention,
and in what manner the same is to be performed, as communicated to me by my
foreign Correspondents, I declare that what I claim is :-
First. In a copying press, the combination with the vertical bed A of the hinged
cover or lid B provided with the hook and the compartment. C for containing the
depending brush D substantially as and for the purpose set forth.
Second. In a vertical copying press, the combination of the vertical bed A boxed
in at the sides as shown and provided with the water-pan compartment E and the
hrush compartment C located side by side and separated by a partition, the water
receptacle F provided with the flanges F¹ resting on the upper edges of said
.

page_text: compartment E and the hinged cover or lid B of suitable length to cover both said com-
partments and provided with a hook 6 located centrally over the brush compartment
for suspending said brush in said compartment substantially as, and for the purpose,
described.
Third. In a vertical copying press, the platen H provided with the supporting steps
or shelves I for sustaining the book above the hinges while in a vertical position,
substantially as, and for the purpose, set forth.
Fourth. In a copying press, the combination of the vertical bed A provided with
the pins T the gear discs L pivotted to said bed, the hooks S and levers K eccentrically
pivotted to said discs, the pins S¹ locking devices O and cams and levers R R¹¹ sub-
stantially as, and for the purpose, described.
