I, GEORGE BISHOP, of No. 23, Soho Square, in the County of Middlesex,
Partner in the Firm of A. Marion, Son, & Co., of the same Place, Wholesale
Stationers, do hereby declare the nature of the said Invention for " IMPROVE-
MENTS IN APPARATUS FOR STAMPING AND MARKING," to be as follows:-
This Invention has for its object improvements in apparatus for stamping
and marking. For these purposes in constructing a portable apparatus for
stamping and marking a frame is used having two side plates or uprights, in
each of which is formed a slot reaching nearly to the bottom of the plate or
upright. At the lower ends of these uprights is fixed a horizontal plate or
frame on which the apparatus stands. In the horizontal plate is an opening
which corresponds in shape with the outline of the stamp or marker, and
the stamp or marker when depressed passes through this opening and presses
on the surface below.
The stamp or marker, of which the form and character will as heretofore
be varied to suit the particular nature of the work it is to perform, bas

working it makes a half turn in rising from and descending to the surface
which is to be stamped or marked. The manner in which the stamp or
marker is caused thus to turn is by means of two pegs or teeth on one of the
uprights, between which a peg or tooth on the stamp or marker enters both
in the up stroke and in the down stroke. The two side plates or uprights
are fixed at their upper ends to a closed vessel, in which a supply of printing
ink is contained. This vessel is fitted with a horizontal partition, which is
perforated with holes, and there is an opening at the upper part of the vessel
covered by a plug or cap fixed fluid-tight by a screw or by other convenient
means. In the under compartment or chamber of this vessel séveral thick-
nesses or layers of woollen cloth or felt are placed, which become saturated
with the printing ink introduced into the upper compartment of the vessel.
The necks or axes of the stamp or marker are received into the ends of a
forked or branched frame, and this frame is fixed to a handle, which for a
hand portable instrument is upright, and is hollow in order to contain a coiled
spring resting at its lower end of an upright on the top of the ink vessel, and by
preference fixed to or forming part of the screw cap or cover used to close
the ink vessel. By this arrangement the stamp or marker when left free
will be raised by the spring and pressed against the saturated cloth, and so it
will become inked. It is desirable when the apparatus is out of use, that
the stamp or marker should be kept out of contact with the saturated cloth;
with this object a stop is applied which retains the stamp or marker from
coning in contact with the inking surface, and the stop is also arranged to
retain the marker or stamp when at its lowest position in order to facilitate
the cleaning of the marker or stamp. In some cases the stamp or marker is
formed with a numbering apparatus consisting of rotating discs similar to
what has been before employed in stamping and marking apparatus. When
thus applying a numbering apparatus it is caused to make its change in its
upward movement, so that the changed number may be inked before the
marker again descends, but this changing of the numbers is, when desired

apparatus is desired to be arranged according to this Invention, the lowe
plate and frame will be modified accordingly.
