GEORGE KISSAM COOKE and EDWARD HURLES, constituting the Firm of
G. K. Cooke, Hurles, & Co., India Rubber Stamp Manufacturers, of 170, Fleet
Street, in the City of London. "IMPROVEMENTS IN THE CONSTRUCTION OF HAND
STAMPS, AND IN THE WORKING PARTS THEREOF." A communication from abroad
by Edward Gumbs, of New York, United States of America.
This Invention relates to certain improvements in the reversing or rotating
mechanism for hand stamps, wherein the die or stamp plate occupies a position
when not in use under and against the inking pad, which is secured in the upper
portion of a stationary frame, which is provided with vertical slots for guiding the
spring handle which carries the rotating die plate.
To the inside of the upper portion, and on one side of the stationary frame, is
pivoted an oscillating link piece formed with an excentric or cam slot, which is
curved in relation to the vertical slot of the stationary inking pad frame so as that
the upper portion of the said curved slot of the link piece coincides with the upper
portions of the vertical slots on each side of the stationary inking pad frame, and the
lower portion of the said curved slot is coincident with the lower portion of the said
vertical slots of the stationary inking pad frame, the middle portion of the curved slot
of the said oscillating link piece being thus eccentric to and to one side of the vertical
slot of the stationary frame. Upon the inner side of the said oscillating link piece

page_text: is secured a stud, which is directly opposite to the centre of the vertical slot of the
stationary frame. The die or stamp plate is carried upon a cross bar or on
centre studs, which said bar or studs is or are passed through the vertical slots of
the stationary inking pad frame, and is or are free to turn in the extremities of the
yoke arms of the spring handle, and said die plate is provided on the side towards
the oscillating link piece, or on both sides if two link pieces are employed, with an
arm, or in the double case with two arms, which arm or arms has or have a vertical
slot, into which takes the pin of the oscillating eccentrically slotted link piece. Now
upon pressing down the handle and the yoke aruns thereof, the turning bar or the
studs carrying the die plate, passing vertically down the slots of the stationary
inking pad frame pushes against the one side of the cam slot of the link piece and
forces it aside, thus displacing the stud thereon; which stud as it is in the vertical
slot of the die plate, and is thus forced to one side, gives the said die plate a quarter
turn with and upon its cross rod or studs; and upon further pressing the spring
handle, the rod still passing down the vertical slot of the stationary frame, presses
against the opposite side of the eccentric slot of the oscillating link piece, and so
returns said link piece to its former position and returns the stud thereof to its
coincident position in regard to the vertical slots of the stationary frame, and
completes the second quarter turn of the die plate upon its cross rod or studs, and
the die plate is brought vertically down by the completion of the downward
pressure of the spring handle yoke upon the paper or surface which is to receive
the impression of the die, which is secured upon the said die plate. Upon removing
the pressure from the handle the die plate rises vertically for a sufficient distance to
remove the die or stamp from the already stamped surface, the cross bar or studs
presses or press against the opposite sides of the link piece, rotates the die plate
half a turn, then strikes the opposite side of the cam slot of link piece and carries
the stamp plate die up against the inking pad out of use and to receive fresh
supply of ink for the next impression, and so on.
Along with the die plate, upon the back part thereof, for using this apparatus as
a dating stamp as well as a fixed die, a block piece is secured of substantially H
form, but with the bar standing between two semispherical sections, and between
these two sections and spanning the bar of the His a sliding piece with a central
longitudinal slot which allows of the said sliding piece being moved backward and
forward. This forms the body upon which the band dating type will be arranged,
and the sliding piece will serve to hold the requisite face of the band type through
the slot of the die plate for giving off its impression. The band type will be
adjusted for alteration of dates by sliding the sliding piece of the body back and
turning the bands in ordinary manner.

GEORGE KISSAM COOKE and EDWARD HURLES, constituting the Firm of
G. K. Cooke, Hurles, & Co., India Rubber Stamp Manufacturers, 170, Fleet
Street, in the City of London. "IMPROVEMENTS IN OR APPLICABLE TO HAND
STAMPS FOR ENDORSING AND SUCH LIKE PURPOSES." A communication from
abroad by Edward Gumbs, of New York, United States of America.
This Invention relates to certain improvements in the operating mechanism and
construction of hand stamps, the same being hereinafter described in reference to
and shown by the annexed Sheet of illustrative Drawings, wherein Fig. 1 repre-
sents an oscillating cam slotted link piece pivotted to the inside of the stationary
frame; Figs. 2 and 3 represent die-plates arranged respectively for simple rotating
die-plate stamps or with flange slot therethrough for additional movable types, as
for dating and changeable expression purposes; Fig. 3a shows the dating type on
its body; Figs. 4, 5, and 6, represent the die-plate and oscillating link piece from
"out of use "
position to " stamping" position; Fig. 7 is general view shewing
stamp in "out of use position without dating appliances attached; Figs. 8 and 9
shew in end view in raised and lowered position respectively; and Fig. 10 inside
view from left of Figs. 8 and 9, the mounting of the dating stamp mechanism on
and combined with the slotted flanged die-plate, Fig. 3, of a rotating hand stamp,
whether said die-plate be rotated as herein shown or otherwise.
To the inside of the upper portion and on one side of the stationary frame A is
pivotted an oscillating link piece B formed with an eccentric or cam slot a which is
curved in relation to the vertical slot b of the stationary inking pad frame A, so as
that the upper portion of the said curved slot a of the link piece B coincides with
the upper portions of the vertical slot b on each side of the stationary inking pad
frame A, and the lower portion of the said slot a is coincident with the lower portion
of the said vertical slots of the stationary inking pad frame A, the middle portion
of the curved slot of the said oscillating link piece being thus eccentric to and
to one side of the vertical slot of the stationary frame, Figs. 1, 4, 6, and 7.
Upon the inner side of the said oscillating link piece is secured a stud c, which is
directly opposite to the centre of the vertical slot 6 of the stationary frame A. The
die or stamp C is carried upon a cross bar or on centre studs D, which said bar or
studs is or are passed through the vertical slots 6 of the stationary inking pad
frame A, and is or are free to turn in the extremities of the yoke arms E¹ of the
spring handle E, and said die-plate Cis provided on the side towards the oscillating
link piece or on both sides if two link pieces are employed with an arm, or in the
double case with two arms F, which arm or arms has or have a vertical slot b', into
which takes the pin c of oscillating specially slotted link piece B. The slots a, b,
and b¹ are made, as shown in the Drawings, wider at their middle portions than at
their ends, to ensure the correct and easy movement of the parts in relation to each
other.
Now upon pressing down the handle E and the yoke arms E¹ thereof, the turning
bar or the studs D carrying the die-plate passing vertically down the slots b of the
stationary inking pad frame A pushes against the one side of the cam slot of the
link piece, and forces it aside, as in Fig. 5, thus displacing the stud c thereon, which
stud c as it is in the vertical slot of the arm of the die-plate C and is thus forced to
one side gives the said die-plate C a quarter turn with and upon its cross rod or
studs D, see Fig. 5; and upon further pressing the spring handle E the rod or
studs D, still passing down the vertical slot 6 of the stationary frame presses against

page_text: the opposite side of the eccentric slot a of the oscillating link piece B, and so returns
said link piece B to its former position, and returns the stud thereof to its coincident
position in regard to the vertical slots of the stationary frame, and completes the
second quarter turn of the die-plate C upon its cross rod or stud D, see Fig. 6,
die plate is brought vertically down by the completion of the downward pressure
of the spring handle yoke E, E', upon the paper or surface which is to receive the
impression of the die which is secured upon the said die plate C. Upon removing
the pressure from the handle the stamp plate C rises vertically for a. sufficient
distance to remove the die or stamp from the already stamped surface, the cross bar
or studs D presses or press against the opposite sides of the slot b of the link piece B
rotates the stamp plate by c half a turn, then strikes the opposite side of the cam
slot b of link piece B, and carries the stamp of die plate Cup against the inking
pad at A¹ out of use and to receive fresh supply of ink for the next impression, and
so on.
With the die-plate upon the back part thereof (for using this apparatus as a
dating stamp as well as a fixed die) slotted bracket arms G are secured, which slots
thereof receive the studs in the ends of the body (see Fig. 3ª) which carries the
adjustable band type, and said body and the type is capable of upward and down-
ward movement in the slots of brackets G to project the requisite dating type
through the slot of die plate C, or withdraw same to readjust the bands of type
for changing the date. To control this projecting and withdrawing action, and to
ensure the due adjustment of the movable type in relation to the slot in the plate C
and to the thickness of the fixed stamp or die thereon.
The side slotted rockers H are pivotted at h to the brackets G and are bound
together by the bar at i passing through projecting arms of the rockers H. The
studs K of the adjustable type body pass through the vertical slots of brackets G
and into curved cam slots of rockers H and are acted upon by said cam slot.
The adjusting screws are screwed through ears on the rockers H so as to act on
studs K when in lowest position of the type body when projected through slot of
plate C and of finger spring m extend from another ear n of bracket G to and
acts on stud o on side of rocker H to retain said rocker in position, in which it
may be placed for or after adjustment of the band type. In conjunction with the
slot of die plate C a flange or lip p of metal on back of said plate C is provided
for regulating the band type against previously to its being carried down into the
slot by swinging the rocker H on their pivots h and carrying with them studs k
of the type body from position shown in Figs. 8 and 10 to the lower projected
position shown in Fig. 9.
In adjusting the band type the required heads of the band are brought around
the body until the said heads are approximately in line, see Fig. 10, and the rocker
from H is partly moved towards the position of Fig. 9 until the heads of the type
are on a level with the back of plate C; any convenient pointed implement, such
as a pencil, is now pressed against the row of type heads, whereby they are laid
perfectly in line and evenly against lip p, which serves as a most effectual guide
for clean entry of the type heads into the flanged slot of plate C.
If it be found that the band types do not project far enough through plate C,
or on the other hand project too far, the screws 1, which bear upon pins k, are to
be adjusted.
This dating and changeable type device is applicable to all hand stamps of the
rotating die-plate class, whether operated by slot 6 device, as herein described, or
by the well known cogs or teeth arrangement, or otherwise, as well as to hand
stamps with fixed die plates wherein dating types or changeable numbers or
expressions are to be used.
Having now described the nature and particulars of the said Invention, we
claim,―
First. In rotating die plate mechanism of hand stamps, the specially centrally
enlarged slotted link piece B carrying the stud c, both in relation to the said vertical
slots b of the frame A, with stud c engaging with the said vertical slot or slots 6¹
