PROVISIONAL SPECIFICATION.
Improvements in Dividers.
HUON ARTHUR MATEAR of 6 Stanley Street Liverpool in the County of
Lancaster, Architect do hereby declare the nature of this invention to be as
follows:-
This invention relates to improvements in "dividers," as used by architects,.
surveyors, engineers, and others, and has for its object to render scales as at present
used, almost unnecessary. In one form of my improved "dividers I provide a
segmental scale piece in any suitable metal or alloy or in ivory, bone or other
adaptable material, attached to one leg of the ordinary form of "dividers" and
moving in a slot provided on the other leg. In another form the scale piece may
be straight, working on a pivot in a slot in such manner as will allow the legs of
the "dividers" to open and shut easily. In a further modification, the scale may
be in form of a spring tape attached to one leg of the "dividers" and the free
end of tape to be attachable to the other leg of the "dividers" by any of the well
known methods.
The tape line may be of silk, steel ribbon, or other material adapted to the
purpose. All the scales as aforesaid or that may be found necessary in practice
are to be arranged to permit of being interchangeable and may be secured to the
"dividers" by means of thumb screws and the divisions on scale pieces may be
marked under any of the systems in use.
Dated this 25th day of January 1893.

COMPLETE SPECIFICATION.
Improvements in Dividers.
HUON ARTHUR MATEAR, of 6 Stanley Street Liverpool in the County of
Lancaster Architect 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 is for improvements in dividers.
A movable scale marked A. Fig. 1 regulated to certain curves, to suit the varied
requirements. The said scale being straight for two thirds of its length and
curved for the remaining one third.
The scale as shewn in Fig. 1 is attached to one leg of the- dividers by a small
screw and runs through a slot in the other leg.
Immediately adjoining the screw afore mentioned, as attached to the leg of the
dividers, is a knuckle joint on the said scale A, which enables the said scale A, on
closing the said dividers to be folded up. The scale as afore mentioned has a
slot at back, for nearly its full length, and has a screw pin on leg of dividers to
keep said scale in accurate position.
The aforesaid scale is interchangeable, to admit of any variety of scale being
used.
The scale may be made in metals, alloys, ivory, bone or any composite materials.
Fig. 3. shews a modification of this invention, with spring measuring tape
attachment, to one leg of the dividers.

page_text: The tape passes through a slot in said leg of dividers, and is attached by screw.
The other leg of dividers is likewise slotted for the tape to pass through. The
spring box of aforesaid tape is then attached to this said leg of dividers by a
swivel joint.
The said tape may be made in silk, steel, or other suitable material.
This spring measuring tape, is to be attached to dividers in place of scale A
Fig. 1, and is made to facilitate the carrying about, of the said dividers.
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
1st. The improved dividers substantially as figured, and described.
2nd. The scale or scales A Fig. 1 being straight for about two thirds and
curved for the remaining third, substantially as herein described with knuckle joint
for the purpose of permitting said scale to be folded up.
3rd. Spring measuring tape attachment Fig. 3. in place of scale A Fig. 1
substantially for the purpose as herein described.
