Improvements in Means for Spreading Ink, or Colour, over Pads
employed in Machines for Stamping or Marking Goods, or for
other Stamping, Marking, or Printing purposes.
I, ALFRED AUSTIN WHITLEY, of Park View, Walmersley Road, Bury, in the
County of Lancaster, Engineer, do hereby declare the nature of my invention
to be as follows: —
The object of my invention is to provide simple and efficient means in connection
with machines for stamping, or marking, goods, or for other stamping marking,
or printing, purposes, whereby ink or colour, is automatically spread over, or
applied to, the pad by which the types, stamp, or marking devices, are inked.
My invention is especially applicable to machines in which the pad moves under
the types, stamp, or the like, to ink them, and then retreats to give place to the
goods to be stamped, marked, or printed. Machines of this kind are described in
the Specification of Letters Patent No. 78 dated 1st January 1895 granted to me.
According to my present invention I mount above the pad, so that it will act
to scrape colour placed on the pad, a blade or scraper, capable of being raised
and lowered in or on suitable guides. The ends of the frame of the pad carry
inclined projections, or catches, which when the pad is near the end of either stroke
lift the blade, or scraper, and keep it lifted for a sufficient time to cause it, when
it again descends onto the pad to be at the reverse side of the ink, or mass of
colour, which is placed on the pad. On the commencement of each stroke the
blade, or scraper, is not raised as the aforesaid projections, or catches, are so shaped
or mounted as to pass without lifting the blade, or scraper, the parts which, at the
end of each stroke of the pad, are acted upon to lift the blade or scraper as afore-
said. Although I have described the invention as applied to machines in which
the pad reciprocates, it may of course be applied to machines in which the blade,
or scraper, reciprocates.
In either case the ink, or mass of colour, is, by the blade, or scraper, forced along
over the surface of the pad at each stroke, and the said surface has thus applied to
it the proper amount of ink, or colour.
Dated this 11th day of May 1897.

I, ALFRED AUSTIN WHITLEY, of Park View, Walmersley Road, Bury, in the
County of Lancaster, Engineer, do hereby declare the nature of this invention
and in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement:-
-
The object of my invention is to provide simple and efficient means in connection
with machines for stamping or marking goods, or for other stamping, marking,
or printing, purposes, whereby ink, or colour, is automatically, spread over, or
applied to, the pad by which the types, stamps, or marking devices, are inked.
My invention is especially applicable to machines in which the pad moves under
the types, stamps or the like, to ink them, and then retreats to give place to the
goods to be stamped, marked, or printed. Machines of this kind are described in
the Specification of Letters Patent No. 78 dated 1st January 1895 granted to me.
According to my present invention I mount above the pad, so that it will act
to scrape colour placed on the pad, a blade, or scraper, capable of being raised,
and lowered in, or on, suitable guides. The ends of the frame of the pad carry
inclined projections, or catches, which when the pad is near the end of either stroke
lift the blade, or scraper, and keep it lifted for a sufficient time to cause it, when
it again descends onto the pad, to be at the reverse side of the ink, or mass of
colour, which is placed on the pad. On the commencement of each stroke the
blade, or scraper, is not raised as the aforesaid projections, or catches, are so shaped
or mounted as to pass, without lifting the blade, or scraper, the parts which, at the
end of each stroke of the pad, are acted upon to lift the blade, or scraper, as
aforesaid.
I will describe with reference to the accompanying drawings an arrangement
according to my invention.
Figure 1 is a front elevation partly in section and Figures 2 and 3 are side eleva-
tions also partly in section of so much of a machine as is necessary to illustrate my
invention. Figure 2 shewing the position when the ink or colour pad is moving
towards the left of the Figure, and Figure 3 showing the position when the ink
or colour pad is moving in the opposite direction.
Figures 4 and 5 are an elevation and plan (drawn to a larger scale) of one of
the catches secured to each end of both sides of the frame of the ink or colour pad.
A represents part of the framing of the machine and B represents the ink or
colour pad.
On each side of the framework. A are guides or standards, C, with
adjustable collars c thereon fixed in position by screws and having at top pads c³
of rubber or the like. Upon these guides or standards are placed the eyes d at the
ends of the bar d which has secured to it the blade or scraper D. At each corner
of the frame of the ink or colour pad B, is a catch E consisting of a bracket e
carrying the pin e on which the piece 3 is hinged, the said hinged piece having a
curved projection upon it in line with runners or small bowls d³ mounted on
pins d' secured to the ends of the blade or scraper D.
The projection is so curved that when its free end rests
on the
stop the bowls d³ will, when the ink or colour pad moves in one
direction (viz. that indicated by the arrow 1 in Figure 4,), not be
acted upon by the projection as the projection will, by coming
in contact with the bowl d³, be turned on its pin ea into the position shewn

page_text: by dotted lines and pass over the bowl and the blade or scraper will not be raised,
but when the ink or colour pad moves in the direction of the arrow 2 in Figure 4
the free end of, the projection et on the hinged piece e³ will enter beneath the
bowls d³ and these will ride up over the top of the said projection e and the blade
or scraper will be raised until the catches have passed the bowls and then will drop
back onto the ink or colour pad on the side of the mass of ink or colour opposite
to that on which it was previously situated and so traverse the ink or colour across
the pad and then be lifted and passed across the mass of ink or colour and so on
at each stroke of the ink or colour pad.
Although I have described the invention as applied to machines in which the
pad reciprocates, it may of course be applied to machines in which the blade, or
scraper, reciprocates.
In either case the ink, or mass of colour, is, by the blade, or scraper, forced along
over the surface of the pad at each stroke, and the said surface has thus applied to
it the proper amount of ink, or colour.
The blade, or scraper, may be made in lengths and divisions be used between
separate masses of ink or colour so that several different inks or colours can be
spread along the pad.
The blades or scrapers may have flexible or rigid edges but preferably they have
rounded metal edges.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed I declare that what I
claim is:
1. In machines for stamping marking or printing purposes, the combination of
a blade or scraper, and means whereby it is lifted over the ink or mass of colour
near the end of the stroke so as at each stroke to descend into a position to pass the
ink or mass of colour across the pad, substantially as hereinbefore described.
2. In combination with machines for stamping marking or printing purposes,
the arrangement of blade or scraper and means for operating it so that it passes
the ink or mass of colour across the pad substantially as herein before described
and illustrated in the accompanying drawings.
