GEORGE KISSAM COOKE of 12 Harp Alley, London "IMPROVEMENTS APPLICABLE
TO DATING AND ENDORSING HAND STAMPS
This invention relates to improvements in or applicable to india rubber dating
or numbering endorsing stamps and refer particularly to those stamps having letters
or figures in relief on india rubber rods fixed on flexible bands which can be turned
as required around an interior fixed piece of suitable form.
In carrying out my invention I proceed as follows:—
I make the supporting type band block (around which the india rubber type
move) hollow, of suitable metal and of a particular form with an opening in the
base thereof to make the block as light as possible. Two lugs are formed on the
enlarged part of the block one on each side each being provided with an opening
for receiving a screw such screws serving to connect the block with the outer
supporting frame. On one of the sides of the narrow part of the block I provide a
small projecting guide which can be moved longitudinally in a guide slot in the
outer supporting frame. This projecting guide serves to keep the block in a
perpendicular position after having been previously adjusted in the supporting
frame by means of the hereinbefore described screws. By moving the, block
longitudinally the moveable type may be placed in the same plane as the stamp
which is fixed on the die plate, in which position they are then held by the said
fixing and adjusting screws and the projecting guide. The die plate has a central
opening and is connected with the outer supporting frame by means of a projection
of a book form arranged in such a manner as to allow of it being placed and
turned on a pin fixed in the supporting frame thus forming a joint such that the
plate can be placed on or taken off as required. The said hooked hinge may have
different forms.
--
The moveable type pass through the central opening in the said die plate and
are placed on a level with the stamp properly so called which is effected by suitably
arranging the supporting type band block as herein before described. Two adjusting
bars turning on the herein before described hinge pin serve to place and keep the
moveable type in a straight line or the said adjusting bars may be applied on the

page_text: die plate when the opening therein is too large to serve for the adjustment and
consequently the type are maintained by the adjusting bars alone.
The advantages derived from my improved invention are as follows:
As the die plate can be changed at will several kinds of different impressions
may be obtained from one and the same stamp.
The special construction of the type band block allows of obtaining better results
at a minimum cost and the whole piece, the weight of which is reduced as much as
possible, may be cast or stamped from a single piece of metal.
The projecting guide allows of keeping the type band block in its proper
position and of arranging the type in their proper order for producing the required
impressions.
The adjusting bars keep the type in a straight line and when it is desired to
change the type this change is rendered much more easy by using these bars than
by any other arrangement hitherto in use.
