Improved Combined Marking Gauge and Compass.
I, HONOR GEORGINA BASSET, of Ivy House, East Woodhay, Newbury, in the
County of Hants, Widow, do hereby declare the nature of this invention to be as
follows:-
My invention has for its object an improved measuring device of the carpenters'
gauge type but differing essentially therefrom in the manner in which the sliding
piece is secured in the desired position.
In the construction of my improved gauge I use a strip of spring metal of
suitable length, width and thickness and bent to a V form, the two arms or straight
portions being however, so twisted that they lie edge to edge.
Sliding on this V plate so as to embrace both arms thereof and force these more
or less together is a rectangular plate or block of metal or other suitable
material.
The inner edge or projections of this sliding plate or block engage with notches
or recesses formed on the outer edge of each arm of the V plate which notches to
be arranged at inches and parts of inches and marked and figured for easy
observation owing to the pressure exerted by the arms in attempting to regain
their normal position. The sliding block or plate is thus securely held in any
desired position and distance from the apex of the V plate at which point is formed
or secured a socket for a pencil or other marking device.
Where found desirable a point may be secured or formed on the lower edge of
the sliding plate or block thus admitting of the device being used for describing
circles in the same manner as a beam compass.

COMPLETE SPECIFICATION.
Improved Combined Marking Gauge and Compass.
I, HONOR GEORGINA BASSET, of Ivy House, East Woodhay, Newbury, in the
County of Hants, Widow, 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 has for its object an improved device of the carpenters' gauge
type, but differing essentially therefrom in the mauner in which the sliding piece is
secured in the desired position.
In the construction of my improved gauge I use a strip of spring metal of
suitable length, width and thickness and bent to a V form, the two arms or straight
portions being, however, so twisted that they lie edge to edge.
Sliding on this V plate so as to embrace both arms thereof and force these more
or less together is a rectangular plate or block of metal or other suitable
material

page_text: The sides of the slot or opening in this sliding plate or block engage with notches
or recesses formed on the outer edge of each arm of the V plate owing to the
pressure exerted by the arms in attempting to regain their normal position, said
notches being arranged to correspond with any suitable scale stamped or otherwise
marked on the arms of the V plate. The sliding block or plate is thus securely
held in any desired position and distance from the apex of the V plate, at which
point is formed or secured a socket for a pencil or other marking device.
Where found desirable a point may be secured or formed on the lower edge of
the sliding plate or block thus admitting of the device being used for describing
circles in the same manner as a beam compass.
A device constructed according to my invention is shown in perspective in the
accompanying drawings, Fig. 1 in which A is the spring plate of metal or other
material bent to a V form with its arms so twisted as to lie edge to edge. At the
apex of this V plate a pencil holder B is provided of such construction that pencils
of different diameter may be secured therein
This holder, of which Fig. 2 is an enlarged sectional elevation and Fig. 3 a
sectional plan, consists in forming in the apex of the V plate or a socket fitting into
or attached thereto an eccentric or "snail" shaped opening into which fits a
tube cut away at that point where it lies within said opening b, as shown in
Fig. 3 and held in position by means of collars & 63. Thus when said tube is
revolved the size of the opening through the whole will be increased or diminished
according to the direction in which it is revolved.
The two arms of the V plate are marked on the upper surface or other suitable
part with any desirable scale and have notches a corresponding with the measure
formed along their outer edges.
Sliding on this V spring plate so as to embrace both arms thereof is a rectangular
or other shaped plate or block C forming the adjustable part of the gauge and
having a point e provided with a cap el projecting from the lower edge thereof by
the aid of which the gauge may be used in a similar manner to an ordinary beam
compass.
The tendency of the arms of the V plate to separate holds the plate or block C
in any adjusted position from which it is prevented from slipping to a great
extent by means of the notches 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.) A gauge consisting of a V spring bar or plate A, a socket B and sliding
plate or block Call constructed and arranged substantially as and for the purpose
described and illustrated in the accompanying drawings.
(2.) In a gauge, compass or like device a V spring bar substantially as and for
the purpose described and illustrated in the accompanying drawings.
(3.) In a gauge, compass or other like device a bolder for a pen, pencil or the
like consisting of opening tube and collars 63 arranged and operated
substantially as described and illustrated in the accompanying drawings.
Dated this 27th day of September 1894.
