I, GEORGE KISSAM COOKE of 12 Harp Alley in the City of London Manufacturer
of Endorsing Presses do hereby declare the nature of said Invention for IMPROVE-
MENTS IN ATTACHING TO THE DIE PLATE OF SELF INKING ENDORSING PRESSES, A
FRAME CARRYING CHANGEABLE DATING, NUMBERING, OR LETTERING MECHANISM to.
be as follows:-
This invention relates to securing to the die plates of self inking endorsing
presses, a hinged Frame holding type bands or type wheels, which are moveable on
a central bearing fixed to the frame so as to admit of the printing characters on the
bands or wheels being moved more quickly and easily, into the required position
preparatory to printing, either in connection with one another at one impression or
on a plane, with a printing die attached to the die plate, and providing for same a
suitable spring fastening in combination with an adjuster and a slot or opening in
the die plate. The type bearing frame is provided with two ears through which
passes a bar, or shaft, this shaft is attached to the die plate of the self inking
endorsing press, so as to allow the frame to make a partial revolution on the shaft.
When turning the frame on the shaft, the type on the type bands or type wheels
are withdrawn from a centrally located slot in the die plate, and exposed for
changing or altering, and may be rotated back to the first position, replacing the
changed type in and through the slot for printing. Also on the same shaft is
hinged an adjusting bar, or guide, which passes down on either side of the type
bearing frame and across the face of same, and on one side of the type, keeping
them in position for entering the slot in the die plate, and when in said slot to
assist in keeping them in straight line for printing. A spring wire is bent in shape
of three sides of an oblong square thus 2]
the second side of which, passes
across the face of the type supporting frame. The parts of the wire bent in shape
of first and third side of an oblong square as described, pass down each side of the
type bearing frame under a second shaft, which passes through said type bearing
frame, and are coiled around the shaft which supports the frame and adjuster.

page_text: After coiling the wire around the shaft, the ends are brought forward and rest
upon the second shaft which projects beyond the sides of the type bearing frame.
The axle which supports the die plate in the endorsing press is bent in crank form
and passes around three sides of the slot in the die plate. Around
that part of the axle which passes in front of the slot, a catch for a spring is placed,
which turns on the axle.
On either side of the adjusting bar are ears or projections, "to hold the type on
the type bearing frame in position through the slot, for printing from," press down
the spring wire which passes across the front of the type bearing frame, and engage
or clip it in the catch which turns on the axle. The wire now acts as a spring,
and not only holds the type bearing frame and type in position, but also presses
upon the ears of the adjuster, holding it firmly down upon the die plate, and yet
allows the type to move by reason of the elasticity of the spring thus fastened,
when sufficient pressure is exerted in the act of printing, thus allowing the type to
assume a position on a plane with a die attached to the face of the die plate, and
giving an equal impression with same-when an impression is made.
Dated this 18th day of January 1884.

page_text: I GEORGE KISSAM COOKE, of 12 Harp Alley, in the city of London Manufacturer
of Endorsing Presses do hereby declare the nature of my said invention for
"IMPROVEMENTS IN ATTACHING TO THE DIE PLATES OF SELF-INKING ENDORSING
PRESSES A FRAME CARRYING CHANGEABLE DATING NUMBERING, OR LETTERING
"
MECHANISM 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 means for securing to the die plate of self inking
endorsing presses a hinged frame carrying type bands or type wheels which are
movable on a central bearing fixed to the frame and capable of being thrown back
out of the slot in the die plate so as to admit of the printing characters on the
bands or wheels being moved more quickly and easily into the required position
preparatory to taking impressions therefrom either in connection with one another
at one impression or on a plane with a printing die attached to the die plate and
also consists in providing for said frame a suitable spring fastening in combination
with an adjuster for keeping the type adjusted to a slot or opening in the die
plate.
In the following particular description reference will be had to the accompanying
sheet of drawings wherein Fig 1 is a perspective view of a hand stamp fitted with
the apparatus.
Fig 2 is a detached plan view of the apparatus in open position for purpose of
altering the type bands or wheels.
Fig 3 a side elevation of same partly in section at line a, b Fig 2.
Fig 3ª is a like view showing the apparatus closed and with the spring and catch
in position.
Fig 4 is also a plan view showing a modification of spring fastening.
The type bearing frame a is provided with two ears b through which passes a
bar or shaft c which shaft is attached to the die plate d of the self-inking endorsing
press and allows the type bearing frame to be thrown over in open position as
shown in Figs 2, 3 and 4 and when in this position the type will be exposed for
changing or altering after which it may be turned back and the type from which
it is desired to take an impression will pass in and through a slot or opening e in
the die plate, as in Fig. 3º.
On the shaft or bar c there is also hinged an adjusting bar f which passes across
on either side of the type bearing frame and across the face of same and against
the side of the type from which an impression is to be taken for the purpose of
adjusting and keeping them in position for entering the slot of the die plate and
also assist in keeping them in a straight line in said slot for printing.
The spring wire g formed up as shown in Figs 2 and 3 passes over the face of
the type and on either side of the type bearing frame and on one side of studs h
projecting from the sides of said frame and the ends g¹, g² are coiled around the
shaft e and are then brought back and spring against the other sides of the studs h
so acting as a spring when the part g³ is held down in position by the catch i as
hereinafter described.
Thus when it is desired to adjust the type through the slot of the die plate for
printing, the part g³ of the spring wire. g will be pressed or pulled down towards
the die plate d and causes the type to pass through the slot in said die plate, and
to keep it in this position the wire engages with the catch i provided for the
purpose turning on axle k which supports the die plate and formed of crank shape
as shown by the drawings.

page_text: The wire will thus act as a spring and not only hold the type bearing frame a
and type in position but allow the type to move by reason of its elasticity when
sufficient pressure is exerted in the action of printing, and assume a position on a
plane with a die attached to the face of the die plate so giving an equal impression
with same when an impression is being made.
g
A modification of the fastener is shown in Fig 4 in which the spring' wire is
provided on the part g³ with a slotted projection g¹ into which the screw upon
the fastening piece on the cranked shaft k will take when the apparatus is closed
and will be held in said slot by the nut m and by the loosening or tightening
of said nut this fastener is made to act as a tension to regulate the impression of
the type.
Instead of the spring piece g being loose on the shaft it may be secured to the
sides of the type bearing frame a.
The screw n holding the cranked shaft k to the die plate d passes through a
slot o in the part of the fastener turning on the cranked shaft k and serves to limit
its movement thereon.
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 :-
Firstly. In self inking endorsing presses the means of attaching to the die plate
the hinged frame or body carrying the type bands or type wheels in combination
with the spring g the catch i and the adjuster f the whole constructed and
operating as and for the purpose as herein set forth and shown by the drawings.
Secondly. In self inking endorsing presses the spring piece g in combination
with the catch fastener i serving to hold the hinged frame or body in position as
herein set forth and shown in Figs 2, 3 and 3° of the drawings.
.
Thirdly. In self inking endorsing presses the spring piece g in combination with
the screw and nut m to hold the hinged frame or body in position and to allow
of regulating the impression of the type as herein set forth and shown by Fig 4 of
the drawings.
