THOMAS BRIGHT 11 Clifton Road in the City of Gloucester Engine Fitter and
Turner do hereby declare the nature of this invention to be as follows :-
The object of my invention is a useful Gauge suitable for all classes of Mechanics.
This Gauge is 2 long 1 wide thick with a 3 inch steel rule A wide or .
This rule and Scriber is movable, answers for depths and lengths, also any bevel or
angle. A small steel Scriber is also provided and will answer for depths and lengths
also Scribing block. Both articles can be used independantly. The rule and Scriber
is fixed on the Gauge by a thumb screw C. One end of scriber at D also answers
for a thickness Gauge, also calipers, point of rule answers for V screw cutting, rule
will also answer for all kind of pitched threads. This Gauge can be made to any
size.
This Invention has for its object improvements in pocket combination tools
suitable for all classes of Mechanics. For this purpose the Tool is designed to form
a combination of several Tools in common use with Mechanics. The Tool is light
& compact, but at the same time being of a size consistent with the dimensions of
the ordinary Pocket Tool. The Guage Plate is provided with an adjustable &
Temovable Rule which serves for "depths " & "lengths," also for the angles & bevels
in general use, which are marked & figured on the aforesaid Guage Plate. In
addition, there is an adjustable & removeable Scriber for guaging "lengths" &
"depths" & a loose Plate which forms a Scribing Block. The Rule & Scriber are
readily removed & may be used independently from each other in the manner &
form illustrated by the diagrams. The Rule, Scriber & Block are controlled by one
Thumb Screw. The curved end of the Scriber will serve for a Thickness Guage also
Calipers, as shewn by the diagrams. The pointed end of Rule is cut to the angle
of 55 degrees to suit Vee Thread Screw-Cutting for all pitches. On the top edge of
Guage Plate, there are three guages cut to the angle of 55 degrees to set point of
tool for Vee Threads. The loose Foot may be detached from the tool & is useful
for marking Key-ways on round shafting. The Guage Plate has three square edges,
to any of which the loose Plate & Clip may be adjusted. The angles marked on
Guage Plate are (1st) 60 degrees, for Hexagons & Drill Guage (2nd) 55 degrees,
for large Vees, Slide Rests & Lathe Beds; (3rd) 45 degrees for Valve Seats, inside &
outside. On the back of Guage Plate there is marked a list of six sets of Change
Wheels for Vee Thread Screw Cutting. The leading screw of Lathe, inch pitch.

page_text: end of Scriber A will serve for Calipers, Levelling Guage, or for marking off centres
of Shafts either round or square. Diagram No. 4 shews tool to answer as a Tee
Square, also Centre Guage for Lathes.

I, THOMAS BRIGHT, of 11 Clifton Road, Bristol Road, in the City of Gloucester,
Engine-fitter and Turner, 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 :-
The Guage Plate E is provided with an adjustable and removable Rule B which
serves for "Depths" and "Lengths," also for the Angles & Bevels in general use, which
are marked in figures on the aforesaid Guage Plate. In addition there is an
adjustable and removable Scriber A for guaging Lengths and Depths, and a loose
Plate F which forms a Scribing block. The Rule B and Scriber A are readily
removed, and may be used independently of each other in the manner and form
illustrated by the drawings filed with the Provisional Specification. (Sheet 2).
The Rule (B) Scriber (A) and Block (F) are controlled by one thumb-Screw (C).
The curved end of the Scriber A will serve for a Thickness Guage also Calepers, as
shewn by the drawings filed with the Provisional Specification. (Sheet 1.) The
pointed end of the Rule B is cut to the angle of 559 to suit V Thread Screw Cutting
for all pitches. On the top edge of Guage Plate E there are three guages cut to the
angles of 55° to set point of tool for V Threads. The loose Foot (F) may be detached
from the tool, and is useful for marking keyways on round shafting. The Guage E
Plate E has three square edges (999), to any of which the loose plate and clip may be
adjusted. The angles marked on Guage Plate E are (1) 60° for Hexagons and
Drill Guage; (2) 55° for large Vees, Slide-Rests, and Lathe-beds; (3) 45° for Valve
Seats, inside and outside. On the back of Guage Plate there is marked a list of six
sets of Change Wheels (see Sheet 2) for V Thread Screw cutting, the leading screw
of Guage, pitch.
DESCRIPTION OF DRAWINGS:
Sheet I shews Plan, Elevation, and Side View of Tool, with Scriber A in position

page_text: Diagram No. 3 shews Tool without Rule B, answering as Scriber and Block.
The curved and pointed end of Scriber A will serve for Calepers, Levelling Guage,
or for marking off centres of Shafts, round or square.
Diagram No. 4 shews Tool to answer as a Tee Square also Centre Guage for
lathes.

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. A Guage providing a movable Ruler, Scriber, and Block.
2. One that can be used for all Lengths, Depths, Bevels, Angles, and Squares; also
for V Threads, and Square Threads.
