PROVISIONAL SPECIFICATION.
An Improved Ruler.
GEORGE HAWES Merchant 16, Harbut Road Wandsworth in the County of
London and PHILIP HOLMES Secretary to a Public Company 154 Camberwell
Grove Camberwell in the County of London do hereby declare the nature of this
invention to be as follows:-
This invention relates to improvement in rulers for ruling straight & parallel
straight lines the object of the improvement being to prevent any ink, dirt or such
other matter as may have accumulated upon the ruler from being transferred to
the paper being ruled, to rule over wet ink without smearing same or getting same
upon the ruler, and generally to facilitate the use of round rulers.
The said improvement consists of the addition of two or more rings made of
wood, vulcanite, rubber or other suitable substance or substances surrounding and
fitting the ruler and either fixed to same in any convenient manner or permitted to
travel along the ruler as desired or with one or more of same fixed at one or both
ends in a convenient manner and with the remainder unfastened.
Where the rings referred to are made of the same material as the ruler the rings
or one or more of the rings may be turned, cast or otherwise manufactured with the
ruler in one piece.

COMPLETE SPECIFICATION.
An Improved Ruler.
We, GEORGE HAWES, Merchant, of 16 Harbut Road, Wandsworth in the
County of London, and PHILIP HOLMES of 154 Camberwell Grove, Camberwell
in the County of London, Secretary to a Public Company, 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 comprises a ruler provided with two or more collars of larger
diameter than the body of the ruler whereby the latter is kept clear of the material
being ruled and the transfer of ink or dirt from the ruler to the paper or other
substance prevented.
In the accompanying drawings
:-
Figures 1 and 2 represent two different forms of ruler constructed according to
our invention.
Like letters indicate like parts throughout the drawings.
A is the ruler which in Figure 1 is shown provided at each end with a collar or
annular projection B which may either be formed in one with A or independently
of it, and of wood, metal or other suitable material as may also the ruler itself.
The collars B may be rigidly secured on the ruler A or mounted so as to be
adjustable along it, or one may be fixed and the other adjustable.
In Figure 2 we show the ruler A provided with collars B of the shape we prefer
to give them when formed of sheet or rolled metal. Each of these collars is in the
form of an annular bead and has a reduced or socket portion B' the latter fitting

page_text: on the end of A which end for this purpose may be reduced as shown at the left-
hand end of Figure 2, under which construction, if the external diameter of said
socket portion B₁ be the same as that of A the ruling surface will be maintained
right up to the bead B.
C is a collar which may be adjusted to any desired position along A.
The annular projections B may be either in the form of discs screwed on the ends
of A or collars as shown or caps fitting on and closing-in the ends of A or, as
before mentioned they may be turned, cast or otherwise formed (as by moulding
for example) as an integral part of A.
It will readily be seen that the main portion of a ruler provided with "collars"
(under which term we embrace all suitable annular projections) as before described
will be held out of contact with the surface over which it is rolled or passed so that
it will neither blot nor smear any wet ink nor transfer to the said surface any dirt
or ink which may have accumulated on the surface of the ruler.
By having one or more of the collars adjustable along the ruler the user is
enabled to adjust them to suit the size of the material on which the lines are to be
ruled so that the main portion of said ruler may be supported out of contact with
the material by at least two of the collars; without rendering it necessary to use
rulers of different length for different sizes of paper or sheets. This provision also
enables the collars to be adjusted to suit the position at which the lines are to be
ruled and overcome any tendency of the paper to bulge upwards as it sometimes
does in books, and come into contact with the main surface of the ruler.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is:
1. The combination with a ruler of two or more collars of larger diameter than
the body of the ruler for the purpose described.
2. The combination with a ruler of two or more collars of larger diameter than
the ruler one or more of which are adjustable longitudinally upon the ruler
substantially as described.
3. The complete ruler substantially as and for the purpose described and
illustrated in Figure 1 of the accompanying drawings.
4. The complete ruler substantially as and for the purpose described and
illustrated in Figure 2 of the accompanying drawings.
