Improvements in Platen Printing Machines for Stretching Blanket
or Sheet, and Preventing Injury to the Hand whilst Feeding.
SAMUEL MOORHOUSE No. 50 Belle Vue Road Leeds, in the County of York,
Draughtsman, and SAMUEL WILLIAM NORTHI No. 8 Rosebank Road Leeds in the
County of York Letterpress Printer do hereby declare the nature of this invention
to be as follows:-
These improvements comprise the application of two swivelling bars attached to
the sides of Platen, one extending halfway down the bottom sides and along the
whole width of the bottom edge of Platen, and the other extending halfway down
the top sides and along the whole width of the front or top edge of Platen, each end
of these bars is provided with a lug, the lugs on bottom bar overlapping the lugs
on top bar at the centre of each side of Platen, thus forming a lap joint through
which is put thumb screws for making the said bars perfectly rigid when screwed
together, midway between the lugs on both bars and the top and bottom of Platen
are bosses through which are put four studs these studs are screwed into the side
Platen, two being for the top bar and two for the bottom bar, the said bars being
free to swing on these studs when the thumb screws are taken out, this being
neessary when a new or clean Blanket or Sheet is required on Platen, the Blanket
or Sheet being firmly fixed between top and bottom edges of Platen and swivelling
bars when screwed together by means of the above mentioned thumb screws. On
the top swivelling bar is cast a plate projecting a few inches on the bar in front of
Platen and extending rather more than halfway across the front from right to left
of said bar this extended portion projects above the carriage whilst the impression
is being taken and lifts out the hand of the attendant from between the Platen and
carriage containing the forme and by this means prevents the hand being caught
and crushed between the said Platen and forme.

SAMUEL MOORHOUSE of No. 50 Belle Vue Road, Leeds in the County of York,
Draughtsman and SAMUEL WILLIAM NORTH of No. 8 Rosebank Road Leeds in the
County of York Letterpress Printer do hereby declare the nature of this invention
[Price 8d1

page_text: and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:--
The object of our invention is to construct an apparatus to attach to the Platen
Printing Machine for preventing injury to the hand of the operator whilst feeding
and we make it in the following manner.
Fig. 1. is an end elevation of our improvement shewing position of Carriage and
Platen when ready for feeding.
Fig. 2. is a plan view of Fig. 1. shewing the projection on front cross bar.
Fig. 3. is an end elevation shewing the position of Platen whilst an impression it
being taken with the projection on front cross bar extending above the carriage.
A is the Platen to which we attach our improvements B are the four studs
screwed into the sides of Platen carrying the two pair of swivelling bars C and D
on the inner ends of which are the lugs E forming a lap joint, through which are
put the thumbscrews F making the bars C and D perfectly rigid when screwed
together, on the outer ends of the bars C and D are round pins G over which is
passed the cross bars H and I, on the outer ends of the pins G are placed spiral
springs J which keep the cross bars H and I pressed against the top and bottom
edges of the Platen A and between which the blanket or sheet is tightly held,
the bars C and D are free to swing on the studs B when the thumbscrews Fare
taken out, this being necessary when a new or clean blanket or sheet is required
on Platen A, the blanket or sheet being firmly fixed between top and bottom edges
of Platen A and the cross bars H and I when the bars C and D are screwed together
by means of the above mentioned thumbscrews F.
On the top cross bar I is the projection K which prevents the hand of the
operator being caught between the Platen A and carriage containing the forme L.
The projection M on the underside of top swivelling bars C and D prevents the
cross bar I being lifted up too high which prevents the inking rollers N coming
in contact with the projection K should the machine be put in motion when the
cross bar I is lifted up. The bottom cross bar H is prevented being lifted too high
by the lugs E on the bottom swivelling bars C and D being unable to pass the
lugs E on the top swivelling bars C and D. The boss on the bottom swivelling
bar C carries a weighted lever P connected with which is the slotted vertical arm Q
to which is attached the adjustable horizontal gripper R, the gripper R carries
another vertical gripper S which prevents the sheet adhering to the type after an.
impression has been taken. The two lugs T on each of the swivelling bars D.
carry the bottom and side feed gauges U and V.
Having now particularly described and ascertained the nature of our said In-
vention and in what manner the same is to be performed we declare that what
we claim is :
1st The projection K on cross bar I.
2d. The manner in which we stretch blanket or sheet on Platen.
