"IMPROVEMENTS IN STAMPING OR ENDORSING MACHINES."
.
The object of this Invention is the obtaining by an improved arrangement of
machine and method or methods of working or actuating the same, greater con-
venience and rapidity than heretofore in such machines as those used by bankers
and others requiring the stamp or endorsement to be larger than the ordinary
portable stamper will effect; it may be thus described:-At or near the base of a
pair of cranes or standards I fit a strong horizontal shaft, with turned and well
fitted bearings at the ends, and upon this shaft I fit and fix a pair of parallel arms
for carrying between them, at their outer or free ends, a cross piece turned and
fitted to work freely in holes drilled in these arms or levers, which cross piece or
shaft also carries the stamp, and is prolonged at right angles with itself and
perpendicular to or from the back of the stamp into a plain parallel rod.
or
I then construct another turned shaft with turned bearings at its ends, and in the
centre a boss and smooth hole at right angles to its longitudinal centre line, this
hole being bored to fit and slide easily upon the before-named parellel rod, and act
as its guide in all positions; the bearings of this latter shaft being supported by and
working freely in the upper overhanging ends of the before-named cranes
standards, these standards having also attached to and between them a vertical
frame or "bed" for the inking pad. The before-named standards and working
parts are fixed upon the bed of the machine in such a manner as to allow an upper
Hap or top board to be hinged and so attached to the bed that its free side, the
front, may rise and fall about two inches, and I then attach this to the before-
named horizontal shaft and arms, by chains or otherwise, in such a manner that the.
pressing down of the front edge or side of the hinged top board shall cause the
before-described parallel arms or levers to leave their vertical position, and the
stamp to leave the inking pad, and after moving about ninety degrees from their
77

page_text: vertical or normal position to assume the horizontal position (both arms and stamp),
and place the stamp upon the paper and stamping block or pad, the former position
being again obtained, when the pressure is removed, by means of a spring or springs
sufficiently strong and elastic to support the hinged top board and lift the arms and
stamp into the vertical position, when the latter will rest against the inking pad as
its stationary or unused position.
The working or actuating of the machine is effected by the pressure of the hands
upon the hinged top board whilst holding the paper to be stamped across the
stamping pad; and, the principal objects of these improvements being, as before
stated, convenience and rapidity, I also sometimes add a simple knee or treadle
action to the before-explained parts, so that the loss of a hand or an arm, or the
loss of the use of either of them, shall not prevent the utility of my improved
machine being realized.

the said William Dawes in the Great Seal Patent Office on the 18th October

IMPROVEMENTS IN STAMPING OR ENDORSING MACHINES."
The object of this Invention is the obtaining by an improved arrangement of
machine and method or methods of working or actuating the same, greater con-
venience and rapidity than heretofore in such machines as those used by bankers
and others,, requiring the stamp or endorsement to be larger than the ordinary
.portable stamper will effect; it may be thus described--At or near the base of a
pair of cranes or standards I fit a strong horizontal shaft with turned and well
fitted bearings at the ends, and upon this shaft I fit and fix a pair of parallel arms,
or other equivalent, for carrying between them at their outer or free ends a cross
piece, turned and fitted to work freely in holes drilled in these arms or levers,
which cross piece or shaft also carries the stamp, and is prolonged at right angles
with itself and perpendicular to or from the back of the stamp into a plain
parallel rod.
I then construct another turned shaft with turned bearings at its ends, and in
the centre a boss and smooth hole at right angles to its longitudinal centre line,
this hole being bored (drilled) to fit and slide easily upon the before-named parallel
rod and act as its guide in all positions, the bearings of this latter or upper shaft
being supported by and working freely in the upper overhanging ends of the before-
described cranes or standards, these standards having also attached to and between
them as a "stay" a vertical frame or "bed" for the inking pad. The before-
explained cranes or standards and working parts are fixed upon the bed of the
machine in such a manner as to allow an upper "flap" or top board to be hinged
and so attached to the bed that its free side, the front, may rise and fall about two
inches; and I attach this flap to the first-named horizontal shaft and radial arms
by chains or otherwise, in such a manner that the pressing down of the front edge
or side of the said hinged flap or top board shall cause the before-described parallel
or radial arms or levers to leave their vertical position, and with them the stamp
to leave the inking pad, and after moving about ninety degrees from their vertical
or normal position to assume the horizontal position (both arms and stamp) and
place the stamp horizontally upon the paper and stamping block or pad, the former
or normal position of all the parts being again obtained, when the pressure is
removed, by means of a spring or springs sufficiently strong and elastic to support
(and lift) the hinged flap or top board and lift the arms and stamp from the liori-
zontal into the vertical position, when the latter will rest against the inking pad as
its stationary or unused position.

page_text: The working or actuating of the machine is effected by the pressure of the hands
upon the hinged top board or flap whilst holding the paper to be stamped across
the stamping block or pad; and, the principal objects of these improvements being,
as before stated, convenience and rapidity I sometimes further increase or
enhance these by adding a simple treadle or knee action to the before-described
parts or machine, so that the loss of a hand or an arm, or the loss of the use of
either of them, shall not prevent the utility of my improved machine being
realized by those who might otherwise be unable to fully obtain its benefits.
In the accompanying Drawings the machine is shewn in its normal or stationary
position with the stamp against the inking pad, Fig. 1 being a side elevation;
Fig. 2, a front elevation; and Figures 3 and 4, parts of the treadle and knee
actions,―

Having now described and particularly ascertained the nature of the said,Inven-
tion, and the manner in which the same is or may be used or carried into effect,
I wish it to be understood that I do not confine or restrict myself to the precise
details which I have described or referred to, as many variations and modifications
may be made therefrom without deviating from the principles or main features of
the said Invention, but what I consider to be novel and original, and therefore
claim as the Invention secured to me by the herein-before in part recited Letters
Patent is,-
First. The general arrangement and construction of stamping or endorsing
machine, or any mere modification thereof, which will produce similar combined
movements or actions.
Second. The employment in such machines of the hinged rising and falling top
board, cover, or "flap," whereby the user is enabled to effect the stamping or
endorsing by the mere downward pressure of the hands whilst holding, and without
loosing hold of either end of the document requiring to be stamped or endorsed.
Third. The addition to such machines of a treadle or knee action, for the purpose
of extending their utility and convenience to such persons as might otherwise be
unable to use the machine advantageously.
.
In witness whereof, I, the said William Dawes, have hereunto set my hand
and seal, this Seventeenth day of October, in the year of our Lord One
thousand eight hundred and seventy-six.
