Lanarkshire, Engineer, do hereby declare the nature of my invention to be as
follows
This Invention has reference to and comprises a new or improved construction, or
arrangement and combination of the parts of that class of rubber stamps in which the
dates are given by one wheel and band of rubber, the months by a second, and the
year by a third, all ranged -side by side round one axis within the stamper;
improvements will render such date stampers more convenient and useful than as
heretofore constructed.
which
The nature and novelty of my invention consist all as follows:-Under one
arrangement susceptible of slight modification in the details, the india-rubber hand
stamping bands are cemented or otherwise secured on narrow endless bands of strong
linen, silk or other non-stretching material, all of one. length or size of loop containing
the thirty one days of the month on the outer printing stamping surface of the india-
rubber band and the second band, the name of the month or the contraction letters
for the month, and the third band the year; and these bands would be all ranged over
their spindles to be turned as hereinafter described, so that they would stamp and read
transversely in the line of axis of the outer wheels, round which they would be made
to turn at the outer end of the enclosing-case of the printing frame. These bands
would be thus arranged over the outer small wheels in a narrow open front ended case
enclosing the mechanism, and attached to the handle at the back close wider end for
the hand of the operator to stamp with it. The case might be formed of thin brass or
other metal having a part open at the two sides to see the working of the bands. The
inner loops of all the bands would pass over larger wheels on an improved actuating
construction of axis or spindle passed through the inner end of the case; and the
centre of the bands at each side would pass over small side guide pulleys, whose axes
could shift outwards on their bearings or spindles in the ends of the case to stretch and

page_text: keep them tight on their inner actuating and outer setting or printing wheels, which
might also have their axes mounted in slots in end of the case to enable the printing
rubber surface to project more or less through the hinged end die plate, printing the
body of the stamp with the changing rubber dates in the centre. The inner moving
wheels of these bands would have four or other number of pitch teeth or pins in them,
and would take into corresponding pitch holes and eyelets secured in the bands,
between the printing type or letters of the bands. Each wheel would be mounted on
a contre spindle of its own, all mounted tubularly ways to rotate on each other on the
central spindle, turning in bearings in the back ends of the hollow case, each spindle
having a milled head on its outer end projecting a little beyond each other. That is
the central spindle with its outer milled head would be secured at its inner end to the
furthest in toothed wheel of the band for stamping the year, while the second spindle
and its milled head working as a tube spindle on the first central solid spindle, would
have its inner end secured to the centre toothed wheel of the band which prints the
month; and the third spindle, as a tubular spindle turning on the second spindle with
its milled head next the end of the frame, would have its inner end secured to the
near toothed wheel of the band printing the days, which would be turned one tooth
every day to give the new date by bringing the proper figure in line with the month
and year of the bands, over the centre of the printing wheels at the outer end of the
stamper; and the second milled head would be turned on the first of each month;. and
all or any one or two of the milled heads may be turned at once when desired, to have
their figures and letters all exactly set in line at the printing end of the stamper, and
be all fixed there by a slot cut in the outer closing end or hinged die plate when that
is used or by a screw on the far end of the inner spindle, or other equivalent, which
would fix all the spindles and prevent them from turning; and although only three
wheels and bands have been described ranged transversely on their longitudinal wheels
and spindles, it is to be understood that any number of wheels and bands may be used
as with the letters of the alphabet on each band, and so be able to set up a namio or
word with any desired number of letters in it; and each set of wheels and bands
would be separated and kept from rubbing on each other by the usual thin division
plates, or it might be thin narrow flanges on their wheels.
Other devices might be made for turning each toothed wheel and band than by
separate tubular telescopic spindles, as by a key passing in through a slot in the inner
spindle until it reached the wheel to be turned by the spindle, or when the bands are
very numerous they might be turned by the fingers direct through the open sides of
the case.

Improvements in and relating to Hand Rubber Dating and other
Stampers.
I, HUGH MCLEAN, Junior, of 3 Whitehill Street, Dennistoun, Glasgow, Lanark-
shire Engineer, do hereby declare the nature of my invention and in what manner
the same is to be performed, to be particularly described and ascertained in and by
the following statement in writing, reference being had to the accompanying Sheet
of Drawings, and to the letters and figures marked thereon, that is to say:-
This Invention has reference to and comprises a new or improved construction, or
arrangement and combination of the parts of that class of rubber stamps in which the
dates are given by one wheel and band of rubber, the months by a second, and the
year by a third, all ranged side by side round one axis within the stamper; which
improvements will render such date stampers more convenient and useful than as
heretofore constructed.
And in order that my said invention, and the manner of performing or carrying the
same into effect or practice may be properly understood, I have hereunto appended an
explanatory sheet of Drawings in which the same reference letters are used to indicate
corresponding parts in all the figures where shown.
Figure 1 is a sectional side elevation to an enlarged size of a hand dating
stamper S, S'as constructed with milled heads outside, and the stamping bands A², A³, A',
which they actuate all in accordance with my improvements, S being the hollow
enclosing case and S₁ the handle; and Figure 2 is a sectional plan as taken near the
line 11 of Figure 1 and showing the serrated actuating wheels formed on the
lower inner tubular spindles a, a, a, Figure 3 is a sectional edge elevation of
the stamper at right angles to the view shown in Figure 1, and showing the dating
band A2 and Figure 4 is a plan view corresponding to Figure 3 looking on the
top C, c, of the stamper and the printing type a, a, al; of the bands A2, A3, A.
Referring to these Drawings, the nature and novelty of my invention consist all as
follows: Under this arrangement which is susceptible of slight modification in the
details, the india-rubber hand stamping bands A2, A3, A4, are cemented or otherwise
secured on narrow endless hands of strong linen, silk or other non-stretching material,
all of one length or size of loop, the first A having the type a² formed on it for the
thiriy one days of the month on the outer printing stamping surface of the india-
rubber band; and the second hand A³ having the type a³ formed on it for the name of
the month, or the contraction letters for the month; and the third band A having the
type a formed on it, for the year. And these bands A, A³, A', are mounted within
the case S over their spindles A, A', A", and toothed actuating wheels a, a¹, all,
formed or fitted on these to be turned as hereinafter described, by milled heads on
their spindles outside the case S so that they may stamp and read transversely in the
line of the axis of the outer bar B fixed across the outer end of the hollow case S, or
it might be wheels on a spindle as an equivalent for the bar B, round which they would

page_text: be made to turn at the outer end of the enclosing case S of the printing frame. These
hands A2, A3, A', are thus arranged over the outer bar B, or equivalent small wheels
in the narrow open ended case or frame S enclosing the mechanisin, and attached to the
handle S' at the back close end for the hand of the operator to stamp with it. The case S
might be formed of thin brass or of composite or other metal or vulcanite, and either
entirely closed in as shown, or have a part open at one or both sides to see the working
of the bands. The inner loops of all the-bands A2, A3, A4, pass over large serrated
wheels a, a, a, formed on an improved actuating construction of axes or spindles A,
A', A, passed through one side of the inner end of the case S; and the centre of
the bands A2, A3, A4, at each side would preferably pass over small side guide
pulleys, whose axes 6 could shift outwards on their bearings or spindles in transverse
slots 63, in the ends of the case S, to stretch and keep them tight on their inner
actuating wheels a, a, a, and outer setting or printing bar B, or it might be.
equivalent wheels when these are used, and which might also have their axes mounted
in longitudinal slots in the end of the case to enable the printing rubber surface to
project more or less through the hinged end die plate C, printing the body of the
stamp e with the changing rubber dates a², a³, a³ in a slot C₁ in the centre. The inner
moving wheels a, a, all of these bands A2, A3, A4, would be made in the form of a
serrated toothed pulleys or they might have a number of pitch teeth or pins in them,
which would take into corresponding pitch holes or eyelets secured in the bands,
between the printing type or letters of the bands. Each wheel a, a', a¹¹, is formed or
mounted on the inner end of a centre spindle A,. A', A", respectively of its own, all
mounted tubular ways or telescopically to rotate on each other on a central spindle D,
secured in the back end of the hollow case S, each spindle A, A, A", having a milled
head on its outer end projecting a little beyond each other on the outside of the case S,
and indicated by the same letters as the spindles A, A1, A
That is, the inner
central hollow spindle A" with its outer milled head is secured at its inner end to the
furthest in toothed wheel all of the band A, against the inner end of the case S for
stamping the year, while the second or intermediate spindle A and its milled head
working as a tube spindle on the first central solid spindle A", would have its inner
end secured to the centre toothed wheel a' of the band A³ which prints the month
and the third or outer spindle A, as a tubular spindle turning on the second spindle A
with its milled head next the end of the frame S, has its inner end secured to the near
toothed wheel a of the band A2 printing the days, which would be turned one tooth
every day to give the new date by bringing the proper figure in line with the month
and year of the bands, over the centre of the printing bar B or wheels in the slot C'
at the outer end of the stamper; and the second milled head A¹ would be turned on
the first of each month; and all or any one or two of the milled heads may be turned
at once when desired, to have their figures and letters all exactly set in line at the
printing end of the stamper, and be all fixed there by a slot cut in the outer closing
end or die plate Chinged at C and clasped by a spring clasp at C³ on the opposite
side to the hinge C, but which might be secured by screws. Or when this outer
hinged slotted plate Ċ is not used, the bands may be secured in position from turning
by tightening up the screw D1 on the far end of the inner spindle D, or other
equivalent, which would fix all the spindles and prevent them from turning. In the
month and year bands A3, A4, the letters of the month and year may be duplicated to
make these bands last longer, or blanks might be left between as at a on which the
type of abbreviated words such as "Paid," Accepted," "Entered," or." Advised,"
might be mounted as shown in Figure 1. Although only three wheels a, a', a",
and
bands A2, A3, A have been described ranged transversely on their longitudinal
spindles A, A, A, it is to be understood that any number of wheels and bands may
be used, as with the letters of the alphabet on each band, and so be able to set up a
name or word with any desired number of letters in it; and each set of wheels and
bands might be separated and kept from rubbing on each other by thin division plates.
or washers indicated at d in Figures 1 and 2, or it might be thin narrow flanges or
shoulders on their wheels, and which washers might be used to give pacing friction to
each wheel a, a, a, to prevent the turning of one spindle moving the other. Or

page_text: otherwise small spring ratchet pawls might be used as indicated in dotted lines at d in
Figures 2 and 3, mounted on a stud d projecting out from the case S, each pawl being
provided with a small blade spring d³ acting on its square eye over the stud d² to keep
the pawl into or out of action as desired and as dotted-in in the two positions in
Figure 3. Other devices might be made for turning each toothed wheel and band
than by separato tubular telescopic spindles, and milled heads A, A1, A
bands are very numerous they might be turned by the fingers.direct through an

Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed I declare that what I
claim is :-
First. The construction or arrangement and combination of parts, of hand rubber
dating, and other stampers, substantially as herein described in reference to and shown
in the accompanying Drawings.
Second. In hand rubber dating, and other stampers, the mounting or forming of
