PROVISIONAL SPECIFICATION.
Means of Rendering Pencils Available for Taking and Retaining
Measurements.
I, HOWARD MATRAVERS ASHLEY, of Ferrybridge, in the County of York,
Engineer, do hereby declare the nature of this invention to be as follows:-
According to my invention, I apply to an ordinary lead pencil a split sleeve which
can slide along it but has sufficient spring to retain its position on the pencil. I graduate
the edges of the slit with inches and parts thereof or with other desired measures.
When a measurement is taken, the sleeve is slid along the pencil until the end of the
pencil or a mark on the pencil appears through the slit at a point corresponding to
tbe dimension, which is thus retained independently of the memory of the operator.
The pencil also may be graduated in the following manner. A number of pencils
are rolled simultaneously over a set of parallel blades which mark on them circular
grooves at regular distances apart. Besides the sleeve sliding on the pencil there
may be a ring or several rings also fitted to slide with considerable friction.
These can be set to graduations on the pencil corresponding to measurements
taken, and the measurements will thus be retained.

1, HOWARD MATRAVERS ASHLEY of Ferrybridge, in the County of York, 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:--
According to my invention I apply to an ordinary lead pencil a split sleeve which
can slide along it but has sufficient spring to retain its position on the pencil. I
graduate the edges of the slit with inches and parts thereof or with other desired
measures. When a measurement is taken the sleeve is slid along the pencil until
the end of the pencil or a mark on the pencil appears through the slit at a point
corresponding to the dimension which is thus retained independently of the memory
of the operator. The pencil also may be graduated in the following manner. A
number of pencils are rolled simultaneously over a set of parallel blades which mark
en them circular grooves at regular distances apart. Besides the sleeve sliding on
the pencil there may be a ring or several rings also fitted to slide with considerable
friction. These can be set to graduations on the pencil corresponding to measure-
ments taken, and the measurements will thus be retained.
Fig. 1 of the accompanying drawing shews a pencil laving a scale of inches
marked thereon; or it may be a scale of centimetres or other unit of measure-
ment. Fig. 2 shows at a the split metal sleeve, which also has a corresponding scale
marked upon it, and at 6 61 62 three split rings. Fig. 3 shews the pencil with the
sleeve a and rings bb1 6 slid thereon. It will be seen that on taking a series of
measurements, the sleeve a can be slid outward so as to bring the corresponding
division of its scale opposite the end of the pencil, and thus record one such measure-
ment while on sliding the rings b b¹³ to certain divisions on the scale of the pencil
they may be made to record one or more other measurements.

page_text: The graduated sleeve a may also be used on a pencil having no scale, without the
rings 6, and one or more of these may also be used on a graduated pencil without
the sleeve a.
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. The use for recording measurements on a pencil, of a siding split metal sleeve
graduated with any desired measure and adapted to slide on the pencil substantially
as herein described.
2. The combination with a pencil having a scale of measurement marked thereon,
of one or more sliding rings or sleeves for recording measurements substantially as
herein described.
