EDWARD ALEXANDER PHILIPS BURT Westwood Cottage, Wellington Road
Bow, E. Chief Wood Measurer Surrey Commercial Docks London, S.E. do hereby
declare the nature of this invention to be as follows :-
The above Rule is for calculating the actual Solid Cubic feet of Trees Round and
square Timber and Wood of every description, shape and size grown and in use.
Gauge Points being marked thereon with small brass pins fully describing same on
the Rule (on Girt line side) as shown on the Drawing, for all the varied systems of
measuring, including "Hoppus "girt system marked H 12 & small brass pin, girt line
side, line D (the divisor 144, and 40 ft. to the load). The "Customs" girt system
marked G. S. & small brass pin, Girt line Side, line D. (the divisor 113 and 50 ft.
to the load). The "Customs" system of measuring by the diameter marked C. D. &
small brass pin Girt line Side line D. (the divisor 183, and 50 ft. to the load). The
Customs systems of Measuring Octagonal or eight sided marked with figure 8 & small
brass pin, with letter D for diameter & letter & for girt-Girt line Side, line D and
Hexdecagonal or sixteen sided marked with figures 16 & small brass pin, with
letter D for diameter & letter G for girt-Girt line side, line D-Masts, Yards, Spars,
Bowsprits, Topmasts etc., etc., either by the circumference (or quarter girt) and by
the diameter Also piles of Deals, Battens, Boards etc., Stacks of Wood of any kind
and in Bulk-Also Baled Goods, Cases, Chests, Boxes, Luggage etc. and every article
which requires Solid Cubic Measurement (feet and parts of feet) including Blocks of
Stone, Planks, Deals, Battens, Boards etc., Wainscot Oak Logs and Railway Sleepers
of every kind and shape.
The above Rule is also intended for calculating the Superficial Measurement of
Planks, Deals, Battens and Boards of every description and size in use, or
any article
which requires Superficial Measurement, and at same time reducing any thickness to
Superficial feet of one inch thick in one operation-Gauge Points being marked
thereon with small brass pins for each thickness say in. thick to 8 in. thick and
being fully described on the said Rule on Inverted side of the Rule line A with the
words superficial measurement reduced to 1 inch thick, as shown on the Drawing.

page_text: The Plank measuring Rule combined so conveniently to the above Slide Cubing
Rule and marked P. M. R is for measuring and taking the dimensions of the goods
and articles as above enumerated. The Index with inches and quarters of an inch are
so placed upon the edges over the Superficial Measurement line, on girt line side also
Inverted line side of the above Rule that it matters not the position of the Rule when in
the measurers hands, the figures (inches and quarters of an inch) are always readable
and in their place-The small Slide attached marked P. M. R. as shown on the Drawing
which move up and down has fixed to it two sinall nibs or arms marked N. A
these are for taking the top and bottom of any of the articles or goods as above
enumerated, in order that the dimensions may be carefully and correctly taken-The
nibs or arms can be made to any length, these work upon Hinges marked H and a
Spring, so that when the Rule is not in use, it can be let down for convenience-as
shown on Drawing, left hand corner (bottom) marked L D. on Girt line side also
Inverted side of the Rule.
The above Rule can be made to any length, but for correctness should not be
shorter than two feet long-It can he made of Boxwood, or any other suitable kind of
Wood, Ivory, Bone etc.

page_text: I here give a few examples showing the practical working, and use of the above
said Rule.
1st Example Having measured and taken the dimensions of a Round Tree, or
Log, length 50 ft. circumference or Girt 12 inches required its Cubical contents
according to Customs Girt system.
Set 50 ft. the length on line (girt line side of the rule) to the Gauge point
marked with brass pin, and words, under Customs Girt divisor 113 on line D.
then against 12 inches the Girt on same line D, will be found 63 feet Cube on
line C, the actual Contents required, all fractions less than a foot are rejected, the
particulars of which stand thus
2nd Example-Required the cubical contents. per.Hoppus Girt System, of a
round tree, or log, whose dimensions are the same as shown in 1st Example, viz.
length 50 ft. girt 12 inches. Set 5 ft. the length on line C (Girt line side of the
rule) to the gauge point marked with brass pin, and the words Hoppus Girt Divisor
144 under then against 12 inches Girt on line D, will be found 50 ft. on line C, the
solid contents required, the particulars of which stand thus
3rd Example required the cubical contents per Customs system by the Diameter
of a Round Tree, or Log, whose dimensions are, length 50 feet and Diameter
15 inches.
Set 50 ft. the length on line C (Girt line side of the Rule) to the Gauge point, on
line marked with brass pin and words under Customs Diameter Divisor 183, and
against. 15 inches the Diameter on same line D, will be found 63 ft. Cube on line C
the solid Contents required; the particulars of which stand thus
4th Example, required the Hoppus contents by the Diameter, of a round Tree, or
Log, same dimensions as shown in last example; viz. length 50 ft. and the Diameter
15 inches.
Set 50 ft. the length on line C (Girt line side of the Rule) to the gauge point on
line D marked with brass pin, and words under Hoppus Contents by Diameter,
Divisor 233, then against 154 inches the Diameter on same line D, will be found
50 feet on line C, the solid contents required; the particulars of which stand thus
5th Example Having measured and taken the dimensions of an unequal sided
piece of Timber, or wood, the length being 20 feet, depth 8 inches, and width
24 inches, required the number of Superficial feet, of an inch thick, contained
therein.
Set 24 inches the width on line C (Inverted side of the Rule) to 8 inches the depth
on line E, marked with brass pin over, on Superficial Measurement line, and then
against 20 feet the length on line A will be found 348 feet on line B, the Superficial
Measurement of 1 inch thick required-the particulars of which stand thus.-

page_text: 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 the following features of novelty on the said Rule (viz., the same Rule with
Gunters lines as used by H.M. Customs, when Timber, and Wood goods, of all kinds
and descriptions, were admeasured by them for assessment of Duty) the features of
novelty are-
1st. Gauge points marked with brass pins for obtaining Cubical Contents of Trees,
Round Wood, per Customs Girt system, divisor 113 and 50 ft. to the Load, the
same being distinctly marked thereon, in letters and figures.
2nd. Gauge points marked with brass pins for obtaining Cubical contents, of Trees,
round Timber, and Wood, per Hoppus Girt system Divisor 144, and 40 ft. to the
Load, the same being distinctly marked thereon, in letters and figures.
3rd. Gauge points, marked with brass pins for obtaining Cubical contents of Trees,
round Timber, and Wood, per Customs Diameter system, divisor 183, and 50 ft. to the
Load the same being distinctly marked thereon, in letters, and figures.
4th. Gauge points marked with brass pins, for obtaining Hoppus contents of Trees,
round Timber, and Wood, by the Diameter Divisor 233,-40 feet to the Load, the
same being distinctly marked thereon, in letters and figures.
5th. Gauge points marked with brass pins, for obtaining the Superficial contents
of 1 inch thick, of Log Timber, planks, and Boards, of all lengths, thickness, and
widths ranging, from of an inch upwards to any thickness.
6th. The measuring attachment which is conveniently attached to the said rule, is
intended for taking the dimensions of Timber and Wood goods of all kind or articles
described above-as it dispenses with one of the ordinary sets of instruments now in
use and is applicable for other purposes.
The above Slide Rule and Measuring attachment can be made to any length, and
can be made of all kinds of suitable Wood, Bone, Ivory, or metal.
The above Slide Rule as a whole can he made to work out numberless calculations,
when its usefulness is fully known-It is the same Slide Rule as used by
H.M. Customs, when all Timber and Wood goods, of every kind and description, were
admeasured by them for duty-with the six features of improvement and invention
added thereto, as above stated.
