PROVISIONAL SPECIFICATION left by the said Alexander Melville Clark
at the Office of the Commissioners of Patents, with his Petition, on the
11th December 1867.
I, ALEXANDER MELVILLE CLARK, of 53, Chancery Lane, in the County of
Middlesex, do hereby declare the nature of the said Invention for "IMPROVE-
MENTS IN PRESSES FOR STAMPING OR ENDORSING," to be as follows:-
This Invention relates to improvements in apparatus for stamping papers
and merchandize, in which the ordinary pad is dispensed with, and a strip
containing ink substituted therefor. This strip may also be applied to all
kinds of stamps or markers in which letters, characters, figures, or other
distinguishing marks are employed. In order to change the dates, months,
and years, I employ a system of adjustable dials, which are held in any
position by a spring.
This Invention is illustrated in the accompanying Drawing, Figure 1 being
a side view, Figure 2 a face view, and Figure 3 a partial section of same.
A, stem or arm carrying the various parts; B, circular chamber; C, circular

page_text: chambers in which is.wound the ribbon or strip containing the ink; D, springs
for keeping the strip in tension; E, dial indicating the mouth; F, dial indicating
the days; G, circular type wheel corresponding to the "day "dial; H, type
wheel of "month" dial; I, screw for securing the dials in position; K, part on
which is indicated the year, name, and address, or a third dial and type wheel
may be employed for indicating the year; L, strip containing ink, which is
wound up in the chambers C; M, spring stop for fixing the "month" type
wheel, the day, and year type wheels; O, tube containing a spring and
presser for operating the stauipers; P, table; Q, pins for setting the dials;
R, point for indicating the position of the fingers on the dials.
SPECIFICATION in pursuance of the conditions of the Letters Patent, filed
by the said Alexan'ler Melville Clark in the Great Seal Patent Office
on the 10th June 1868.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, ALEXANDER
MELVILLE CLARK, of 53, Chancery Lane, in the County of Middlesex, send
greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by. Her Letters
Patent, bearing date the Eleventh day of December, in the year of our
Lord One thousand eight hundred and sixty-seven, in the thirty-first year of ller
reign, did, for Herself, Her heirs and successors, give and grant unto me, the
said Alexander Melville Clark, Her special licence that I, the said Alexander
Melville Clark, my executors, administrators, and assigns, or such others as
, the said Alexander Melville Clark, my executors, administrators, and assigns,
should at any time agree with, and no others, from time to time and at all
times thereafter during the term therein expressed, should and lawfully might
make, use, exercise, and vend, within the United Kingdom of Great Britain
and Ireland, the Channel Islands, and Isle of Man, an Invention for
"IMPROVEMENTS IN PRESSES FOR STAMPING OR ENDORSING," a communication
to me from abroad by Edouard Cornélis, Merchant, of 29, Boulevart St.
Martin, Paris, upon the condition (amongst others) that I, the said Alexander
Melville Clark, my executors or administrators, by an instrument in writing
under my, or their, or one of their hands and seals, should particularly describe
and ascertain the nature of the said Invention, and in what manner the same
was to be performed, and cause the same to be filed in the Great Seal Patent
Office within six calendar months next and immediately after the date of the
said Letters Patent.

page_text: NOW KNOW YE, that I, the said Alexander Melville Clark, do hereby
declare the nature of the said Invention, and in what manner the same is
to be performed, to be particularly described and ascertained in and by the
following statement, reference being had to the Sheet of Drawings hereunto
annexed, and to the letters and figures marked thereon (that is to say):-
This Invention relates to improvements in apparatus for stamping and
dating papers and merchandize, in which the ordinary inking pad is dispensed
with, and a strip containing ink substituted therefor.
This strip may
also be applied to all kinds of stamps or markers, in which letters, characters,
figures, or other distinguishing marks are employed. In order to change the
days, months, and years, I employ a system of adjustable dials, which are held
in any position by springs.
This Invention is illustrated in the accompanying Drawing, Figure 1 being
a front view, and Figure 2 a side view of the apparatus; Figure 3 is a
vertical section of the type wheels. A, stem or arm carrying the various
parts; B, circular chamber; C, circular chambers in which is wound the ribbon
or strip containing the ink; D, springs for keeping the strip in tension; E, dial
indicating the month; F, dial indicating the day; G, circular type wheel
corresponding to the "day" dial; H, type wheel of "month" dial; I, screw
for securing the dials in position; K, part on which is indicated the year, name,
and address, or a third dial and type wheel may be employed for indicating
the year; L, strip containing ink, which is wound up in the chambers C;
M, spring stop for fixing the "month" type wheel in position; N, spring
acting on the day and year type wheels; O, tube containing a spring and
presser for operating the stamper; P, table; Q, pins for setting the dials;
R, pointer for indicating the position of the figures on the dials.
Another improvement consists in the mode of manufacturing the type wheels
or discs applicable for stamping and other purposes. These wheels are moulded
and cast of steel or other metal or material, and instead of forming the letters,
figures, or characters on their periphery by the aid of galvanoplasty engraved
rollers or other means, I obtain them by the moulding above-mentioned,
whereby a great saving of labor is ensured. The disc are hollowed at their
centre and divided radially into a certain number of parts, so that the blocks
serving to produce the impressions in the sand may be readily brought to the
centre for the purpose of withdrawing them from the mould.
This improved mode of forming the type wheels or discs is illustrate:l in
the Drawings, Figure 4 of which shows a plan and section of a disc a for
keeping the blocks b in position during the moulding. These blocks are
represented in different positions in Figures 8, 9, and 10.
Figure 5 shows a

page_text: face view of a moulding disc provided with radial divisions, the block b being
fixed to said disc by pins d. Figure 6 is an edge view of the disc, and
Figure 7 a view of the reverse side to Figure 5. Lastly, Figure 11 shows
the central boss f received in the hollow centre 9 of the discs.
Having described the nature of this Invention and the manner of performing
the same, I declare that what I claim as the Invention to be protected by the
herein-before in part recited Letters Patent is,-
First. The combination and arrangement of parts comprising the improved.
stamping apparatus herein-before described and represented in the Drawings,
provided with an inking strip to be used as a substitute for the pad usually
employed.
Secondly. The adjustable type wheels held in position by springs for
changing the dates, months, and years, arranged and operated as herein-before
described.
Thirdly. I claim producing the type wheels or discs by moulding them as
herein-before described, whether applied to this or other kinds of stamping
apparatus.
In witness whereof, I, the said Alexander Melville Clark, have hereunto.
set my hand and seal, this Ninth day of June, in the year of our
Lord One thousand eight hundred and sixty-eight.
