IMPROVEMENTS IN INKING-PADS
Year: 1884

page_text: COMPLETE SPECIFICATION.
I CHARLES WALTON CRUTSINGER, of the City of Saint Louis, in the State of
Missouri, and the United States of North America, Manufacturer of Printers
Rollers do hereby declare the nature of my Invention for IMPROVEMENTS IN
INKING-PADS and in what manner the same is to be performed to be particularly
described and ascertained in and by the following statement :-
The Invention relates to a device for the inking of cancelling and other hand-
stamps.
In the Drawings: Figure 1 is a top view of the pad. Figure 2 is a top view
with the felt cover removed and part broken away.
Figure 3 is a vertical section at 3, 3, Figure 1.
A, is the body cast of elastic material such as printers' roller composition or
rubber or any other flexible material suitable for the purpose.
It is not thought necessary to describe the composition of which printers' rollers
are made as the compositions are various and many of them well known.
The body has preferably a flat base a and has an ink recess a¹ containing a
number of concentric or other ribs or walls or pillars a³ whose upper edges are all
level with the sides of the recess.
Channels a³ are made in the walls a³ to give passage for the ink to all parts of
the recess a¹.
The ink is fed to the recess through a mouth B, having a tube 6 let in as a
bushing to receive a cork or plug or cap C.
The bushing or tube b may be made with an interior screw-thread and the plug C
screwed therein.
D, is the cover or pad proper which closes the recess a' said cover consisting of
felt, printers' blanketing, or other porous material that will permit the passage of
ink and will ensure an even application of it to the salient parts of the face of the
stamp.
The marginal connection of the pad or cover D, to the body of the pad is made
watertight so that there will be no escape of ink.
The felt cover D, may be attached to the body by any suitable means.
When the body has been made of roller composition herein before mentioned, I
have attached the cover to the body by softening the top of the latter with heat
after it has been taken from the mould and then pressing the cover down on the
softened surface of the body.

page_text: It will be understood that the cover is made to adhere to the tops of the walls
and thus gives them transverse support.
The filling mouth B, is not essential because the ink recess may be filled once for
all when first made; or the recess may be refilled when empty by raising one edge
of the cover, or by removing the cover D.
When thin ink is used, the recess a³ may be loosely filled with wool or equivalent
material to check the agitation of the ink on the impingement of the stamp and to
elevate it by capillary attraction.
I do not confine myself to the described form of elastic supporting walls a for
the shape is immaterial so that they support the porous cover D in a horizontal
position while allowing its depression by the stamp.
The pad may be connected with a vessel containing ink by a pipe communicating
with the mouth B, and closed by a faucet.
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:
1. In an inking pad the combination of a body having an ink recess with elastic
walls and a porous cover secured to the body and walls substantially as set forth.
2. A pad cast of elastic material, the said material forming an ink-chamber and
supports in said chamber for a porous cover, as set forth.
3. The combination of elastic body, feed mouth fitted to receive a stopper, an
ink chamber with elastic supports being formed of the elastic material of the body
and a porous cover, as set forth.
