Improvements in Ranging Poles.
I, WILLIAM WARDLAW SCLANDERS, 22, Union Street, Inverness, Scotland, N.B.
Gentleman 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 :-
My invention relates to Improvements in Ranging Poles and has for its object to
render same extremely portable so that the surveyor or assistant will be enabled to
carry one, two, or more poles with the greatest ease without in any way interfering
with his general duties such as measuring &c.
In carrying my invention into practical effect I form the ranging pole of several
lengths of steel tubing or other suitable material each length sliding telescopically
within the other, the end of the lower and outer tube being brought to a point and
loaded with metal or wood secured by screws or fixed in any suitable manner.
The end of each tube, sliding within another, is furnished with a circular flange
of such a size that it will just fit the tube into which it is designed to enter, thereby
causing same to slide easily and truly, while the top or neck of each tube is furnished
around its inner periphery with a stiffening or strengthening ring. The length of
tubing when drawn out is prevented from collapsing by means of a spring clip
consisting of a semi-circular spring rivetted or suitably fixed near the top of each
tube, the other or free end being furnished with a stud which passes through a hole
near the top of the outer tube and through a corresponding hole near the bottom
of the inner tube, which is brought opposite the aforementioned hole in the
outer tube when the said inner tube is drawn out. I further provide means for
enabling the flag to be easily rolled up, consisting of a piece of wire wound around
a screw entering the end of the last length of tubing and bent over so as to pass
across the flag, the other end being wound around the tube just below the said flag
so that the wire is always pressing against the flag, the said wire being so attached
as to allow the tube to easily rotate without turning the wire.
In order that my invention may be more fully understood, I will now proceed to
describe same with reference to the accompanying drawings in which
Fig. 1 is a longitudinal section of the pole expanded or open ready for use and
Fig. 2 is a similar view of the pole collapsed,
Fig. 3 is a detail of the joint at an enlarged scale,
Fig. 4 shows two views of the spring clip,
Fig. 5 is a cross section on line x x of Fig. 1.
Fig. 6 is a view of the flag rolling device at an enlarged scale.
Like letters of reference indicate corresponding parts throughout the drawings.
My improved ranging consists of short lengths of tubing t the end of the outer one
being brought to a point p and loaded with wood w, the end of each tube sliding within
another is furnished with a flange so as to cause the said tube to slide easily and
firmly, and the top or neck of each tube is furnished with a strengthening ring r
which also serves for preventing the inner tube from being completely drawn out.
The clip c consists of a flat spring bent into a semi-circular form and rivetted or
otherwise fixed at one end to the top of the tube, the free end being furnished with
a studs passing through a hole formed in the tube to which it is rivetted and also
through a corresponding hole formed near the bottom of the inner tube as shown
in Fig. 1 the said stud being withdrawn by hand when it is required to collapse the
pole. The flag winding device consists of the wire w' attached to the screw s¹
entering the end of the last length of tubing the said wire being bent across the
flag and wound round the tubing, just below the flag in such a manner that it is

page_text: free to revolve without turning the wire, the said wire pressing against the flag f¹
thereby causing it to roll up easily and neatly.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. The new or improved ranging pole constructed of lengths of tubing t sliding
telescopically one within the other, furnished with flanges f, strengthening rings r,
spring clip c, and flag rolling mechanism w¹ s', substantially as herein described and
shown and for the purpose set forth.
2. The new or improved ranging pole arranged, constructed, and operated,
substantially as herein described and shown and for the purpose set forth.
Dated this 20th day of February 1894.
