I, ROBERT CUMMING ANNAND of South Shields in the County of Durham
Newspaper Publisher do hereby declare the nature of my invention for "IMPROVE-
MENTS IN PEN WIPERS to be as follows
"
-
My improved pen wiper consists of two rollers mounted side by side, one roller
has round it a series of parallel semi-circular grooves, whilst the other roller has
upon it a corresponding series of semi-circular projections which enter into the
grooves on the first roller
A ratchet or catch is provided so that the rollers can
tuin freely in one direction but not in the other
The pen to be wiped is inserted between the two rollers, the convex side of the
pen lying in a groove in one roller and the concave side upon the corresponding
projection on the other roller The rollers turn and allow the pen to enter easily,
but when it is drawn back the rollers cannot move and so the desired rubbing or
wiping action is obtained.

-
The different grooves with the corresponding projections may be made of
progressive sizes to suit various pens
I prefer to cover the rollers with india rubber in a laminated form, the laminae
being radial and running lengthways of the rollers

manner the same is to be performed to be particularly described and ascertained in
and by the following statement

My improved penwiper consists of two rollers mounted side by side, one roller
has round it a series of parallel semi-circular grooves, whilst the other roller has
upon it a corresponding series of semi-circular projections which enter into the
grooves on the first roller. A ratchet or catch is provided so that the rollers can
turn freely in one direction, but not in the other.
The pen to be wiped is inserted between the two rollers, the convex side of the 1
pen lying in a groove in one roller and the concave side upon the corresponding
projection on the other roller The rollers turn and allow the pen to enter easily,
but when it is drawn back the rollers cannot move and so the desired rubbing or
wiping action is obtained,
The different grooves with the corresponding projections may be made of 1
progressive sizes to suit various pens.
I prefer to cover the rollers with india rubber in a laminated form, the laminæ
being radial and running lengthways of the rollers.
In order that my said invention may be fully understood and readily carried
into effect I will proceed to describe the drawings hereunto annexed.
DESCRIPTION OF THE DRAWINGS.
Figure 1 18 a mde elevation and Figure 2 is a plan of a penwiper made in
accordance with my invention.
Figures 3 and 4 are transverse sections of the two rollers
Figure 5 is an end elevation of the rollers the base frame being removed.
a is the base frame b bare parallel spindles or axes mounted in the base frame
and able to turn freely. c. c¹, are two rollers of vulcanized india rubber mounted
on the spindles b b and meeting together in the middle These rollers have
laminae passing longitudinally along the rollers and projecting radially from them
as the drawings clearly show c* is a ring of internal ratchet teeth on one of the
rollers d is a finger or pawl mounted on one of the spindles b b, it can turn
freely upon the spindle it allows the rollers where they come together to rotate in
a downward direction but by engaging with the teeth c* it prevents movement in
a contrary sense e is a shield extending across the rollers and fixed at its ends to
the base frame, in this shield there are holes or mouths e¹ of a shape to admit of $
a pen being inserted through them, they are so placed that the pen entering
through the hole in the shield passes down between the rollers The rollers turn
freely as the pen descends between them but when it is drawn back they do not
revolve and then the lamina on the surfaces of the rollers retain the ink whilst
the pen 18 withdrawn.

page_text: The pen wiper shown by the drawing has three separate mouths for the
insertion of the pen but obviously it may be made narrower with two or with one
mouth or wider with an increased number of mouths if desired.
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 18-
1 A penwiper consisting of a pair of rollers having suitable wiping surfaces and
which rotate to allow the pen to enter between them, but remain stationary whilst
the pen is withdrawn so that the pen during withdrawal is rubbed by the wiping
surfaces substantially as described
2 Penwipers having rollers with surfaces of india rubber in a laminated form
by which ink is removed from pens substantially as described
