Improvements in Eraser Attachments for Pencils and the like.
I, REGINALD HADDAN, of the Firm of Herbert Haddan and Co., of
18, Buckingham Street, Strand, W.C. London, Patent Agent, do hereby declare
the nature of this invention, a communication to me from abroad by Charles
Frederic Wickland, Manufacturer and Salesman, and Horace Stephen Buckland,
Attorney-at-Law and Manufacturer, both of Fremont, in the County of Sandusky,
and State of Ohio, United States of America, 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 pencil-attachment, the primary object being to provide
an eraser and knife-blade holder at the end of a pencil, and to construct said
holder in two parts, the one part being adapted to telescope or fit within the other
and carrying the eraser and knife blade at opposite ends respectively, and the other
or receiving-part having sufficient length to receive the knife blade and blade
bearing end of the knife-blade-carrying member.
In the accompanying drawings,
Figures 1, 2 and 3, are elevations of a pencil provided with our improved
attachment, portions being broken away and in section to reduce the size of the*
figures and to more clearly show the construction.
This improved pencil attachment involves two parts or members A and B,
member A being tubular and adapted to be mounted or slipped upon the end of the
pencil and member B being provided with a cutting blade C and an eraser D at
opposite ends, respectively, and adapted to be held within and actuated end wise of
member A. Member B of the pencil-attachment illustrated in Figs. 1 and 2 is
reversible end for end, that is, either end thereof is adapted to be inserted into
member A; hence as the knife-blade is called into requisition the eraser-bearing
end of member B is inserted into member A, and, if the eraser is to be used, the
blade-bearing end is inserted into member A.
The tubular or receiving member A of our improved attachment has such length
that it will not only accommodate the mounting of it upon the end of the pencil,
but will also accommodate the reception of both the knife-blade and knife-bearing
end of member B when the knife-blade is unemployed.
Member B of our improved attachment may simply be capable of being slid into
member A, as shown in Fig. 2, or, it may be externally screw threaded at opposite
ends as at b, to engage corresponding threads internally of member A, as shown
in Fig. 1. or, if desired, member A may be elongated as shown in Fig. 3, wherein
member B is located within and adapted to slide end wise of member A, and
wherein each end of member A is adapted to be slipped or mounted upon the end
of the pencil, and wherein the blade and eraser borne by member B are adapted to
be exposed at opposite ends of member A, respectively. In the construction
illustrated in Fig. 3, the blade or the eraser is exposed for service according as
member B is slid in the one direction or the other, part B being actuated by means
of an external pin or lug b' projecting laterally from said part and engaging a
longitudinal slot a in member A, the length of said slot being such as to
accommodate the required sliding movement of member B, and part A is provided
with two notches a', a² in open relation with slot a and located such a distance
apart that notch a¹, or notch a³, shall be adapted to be engaged by pin or
projection ¹, ou member B according as part B is actuated into the one or the other
of its two adjustments, pin or member when opposite either one of said notches
being adapted to be brought into engagement with the respective notch by turning

page_text: part B somewhat laterally, and the size of notches a¹, a², is preferably such
relative to the thickness of pin or member 61, that said notches shall be adapted
to be tightly engaged by member ', so that part B shall be held in the desired
adjustment.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what I
claim is ;
1. A pencil-attachment consisting of a tubular or hollow member adapted to be
connected to the end of a pencil, and a knife-blade and eraser-bearing member
adapted to engage the tubular or hollow member internally the knife-blade and
eraser being located at opposite ends of the supporting member, respectively, the
latter being adapted to be actuated so as to expose the eraser or the knife-blade
as desired, and the tubular or receiving-member having sufficient length to
accommodate the reception of the knife-blade of the blade and eraser-bearing-
member, substantially as set forth.
2. A pencil-attachment, substantially as shown and described.
