COMPLETE SPECIFICATION.
An Improved Protector for Ink or other Erasers.
We, JOHN KENNETT RAFFORD, of 30 and 32, Ludgate Hill, London, E.C., Rubber
Stamp Manufacturer, and ALFRED JERROLD NATHAN, of 17, Farringdon Avenue,
London, E.C., Merchant, 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 :-
:-
This invention relates to an improved protector for ink or other erasers and it has
for its object to provide such erasers with a protective case or cover which may be
readily removed when it is desired to use the eraser and which will effectually pre-
vent any injury to the erasive substance or composition employed, and at the same
time keep it clean when carried in the pocket.
In carrying the invention into effect we construct an approximately semicircular
case of any suitable width and of any suitable metal such as brass, vulcanite,
celluloid, or other substance may be employed and within which is pivotally secured
a semicircular disc of rubber, in the case of a pencil eraser, or a rubber composition
The rubber or the like
or other material or materials in the case of an ink eraser.
is secured to a sheet metal or other base, the sides of which are provided with a
number of teeth which when the rubber or other substance has been placed therein
are turned or pressed inwards securing the same to the straight portion of the semi-
circular disc and having provided at one end a projection with a button designed to
facilitate the rotation of the said disc by the fingers and which projection engages
with slots formed in the protector at each end and which serve respectively to keep
the eraser fixed when exposed or covered. A pin also passes through the centre of
the frame to which the disc is secured and is rivetted upon the sides of the outer
case.
In order that this invention may be the better understood drawings are appended
in which
Fig. 1 is a side elevational view showing the rubber or the like exposed.
Fig. 2 is an end view.
Fig. 3 is a side view with the protector turned to cover the rubber or the like.
Fig. 4 is a sectional view of the protector.
Fig. 5 is a side view of the rubber removed from the protector, and
Fig. 6 is a section of Fig. 5.
A is the protector which as shown consists of an approximately semicircular
case which may be of metal or other suitable material and of any convenient width
and which is formed with two side pieces joined at their peripherys to a plate, the
whole forming a semicircular box or case open at the top and having formed at
both ends of the mouth slots or openings B B see Figs. 2 and 4, and having in
addition holes C C formed in the sides, such holes being the centre of the circum-
ference of the outer case, and through which holes passes a pin secured to the
metal base D to which is secured the erasive composition. This base which may
be of metal or any other suitable material is in the present case formed from a
piece of sheet metal and is turned up at the sides and ends so as to surround the
base of the rubber or the like disc E and which disc is secured therein by a number
of teeth F formed at the upper edges of the sides of the base D and which teeth

page_text: are pressed inwards when the rubber is placed in position securing the disc thereto
as shown in Fig. 6. At one end of the base D is secured a projection G provided
with a head H and which projection, when the disc E. is exposed or covered,
engages with the slots B B formed in the protector A.
.
When in use the disc E is exposed as shown in Fig. 1 and the projection G is
engaged with the slot at the left hand side of the protector. When the disc E is
not required the protector is turned by means of the head Hupon the projection G
until the whole disc is covered when it will present the appearance shown in Fig. 3
the projection G then engaging with the slot upon the right hand side of the pro-
tector, the whole when in this position may be conveniently carried in the waistcoat
pocket, the protector effectually preventing the rubber or the like from becoming
dirty or damaged. It is obvious that the disc E may, if desired, be formed of ink
and pencil eraser, one half, or such proportions of the disc as may be found con-
venient, being formed of rubber and the other of ink erasing composition, and the
disc may instead of being formed circular, may be square or of any other desired
outline of such dimensions as to permit of the same being enclosed within the
protector.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that what
we claim is :-
The improved protector for ink, pencil, or like erasers consisting of a case or
cover pivotally secured to the erasive medium and capable of being turned by suit-
able means so as to surround the said medium and protect the same against injury
or dirt, substantially as described and shown by the accompanying drawings.
