page_text: LETTERS PATENT to John Mold, of No. 6, Portland Terrace,
Westmoreland Road, Walworth, in the County of Surrey, for
the Invention of "IMPROVEMENT OR ADDITION TO AUGMENT CON-
VENIENCE BY TRANSFORMATION AND FACILITY THE DIFFERENT LINES
REQUIRED IN THE ERECTION OR MANUFACTURING EDIFICES OR STRUC-
TURES, BY APPARATUS, TOOLS, OR INSTRUMENTS SUITABLE FOR THE
DIFFERENT CAPACITIES OF OPERATIVES, AND GENERAL SURVEYING."
COMPLETE SPECIFICATION filed by the said John Mold, at the
Office of the Commissioners of Patents, with his Petition and
Declaration, on the 6th December, 1858, pursuant to the 9th
section of the Patent Law Amendment Act, 1852.
5 TO ALL TO WHOM THESE PRESENTS SHALL COME, I,
JonN MOLD, of No. 6, Portland Terrace, Westmoreland Road, Wal-
worth, in the County of Surry, send greeting.
WHEREAS I am in possession of an Invention for "IMPROVEMENT
OR ADDITION TO AUGMENT CONVENIENCE BY TRANSFORMATION AND FACILITY

page_text: THE DIFFERENT LINES REQUIRED IN THE ERECTION OR MANUFACTURING
EDIFICES OR STRUCTURES, BY APPARATUS, TOOLS, OR INSTRUMENTS SUITABLE
FOR THE DIFFERENT CAPACITIES OF OPERATIVES, AND GENERAL SURVEYING,"
and have petitioned Her Majesty to grant unto me, my executors,
administrators, and assigns, Her Royal Letters Patent for the same,
and have made a solemn declaration that I verily believe myself to be
the true and first Inventor thereof.
NOW KNOW YE, that I, the said John Mold, do hereby declare
the nature of my said Invention, and in what manner the same is to be
performed, to be particularly described and ascertained in and by the
following statement, reference being had to the Drawings hereunto
annexed (that is to say):
In describing the nature of my Invention, I refer to the system
required in constructing the various compartments of erections, and the
various means required to accomplish adjustment, and to augment to
the different parts or compartments and accessories by combining the
different stories, &c., with strength, appearance, convenience, and dura-
bility, and represent to notice that compartment assigned to connect the
different floors or stories of edifices, mansions, or buildings, in such
.forms and in such a manner as to meet the requisite conveniences, &c.,
required, and cannot be well constructed without adjustment in manu-
facturing as well. The white fabric, as a spiral staircase, is a favorite
plan, but, like others, liable to the same inconveniences of persons
meeting, &c., in ascending and descending, which is entirely obviated by
the simple addition of running the treads and risers through the whole
diameter, instead of stopping at the centre, and by that addition or
augmentation produces two staircases instead of one on the same plan,
independent of each other, with the exception of landings, and may be
termed a double spiral, and extended, where required, two continued
rails to each, and protecting all landings, &c. connected; no carriages
of whatever description required. The nature of adjustment is con-
sidered in union with the above statement and forthcoming introduction,
which is to subdivide, and by transformation, for convenience and
facility, to furnish the different capacities of operatives, and in manufac
turing either in preparation or operation, and is performed by each,

page_text: according as ability may require, and consist in consolidating a
sufficient number of tubes into one form which will operate upon the
various lines of direction from a common level to a theodolite; from
that are subdivided, and by transformation of tubes, operate and become
suitable to requisite purposes. In reference, as above stated, and to
the more fuller description by diagram annexed. A dial plate for lineal
land, &c. purposes, of wood, composition, or metal, divided and sub÷
divided in such a manner as to exemplify by a three finger indicator
the different items as required at the end of each proceeding. The
dial, instead of being fixed, is moveable, and slips to a starting point,
leaving each item separately and visable to the naked eye the number
of miles, &c. run over by the counting dial, to the extent of fifteen miles.
The shifting plate or dial is subdivided from one mile,,,, and
component parts; acres,,,; furlongs, 1 to 8; chains, 1 to 80%;
poles, 1 to 320; yards, 4 to 440, accounts for the subdividing required
on the plate. A further description reference for the manufacturing,
&c. of continued hand rails, before mentioned, by reference to diogram
No 10 by dotted lines, commencing with a scroll from the hall floor,
tracing the direction, finishes at the first step with a scroll, which
guards one staircase, leaving the other unprotected, with a view of
different choice forms. Strong dots represent banisters, &c.; treads
and risers, if of fir or deal, 14 in thickness. A piece of a semicircular,
glued and fixed on both sides the riser, together makes 7, struck
round grain with the riser; the trend in the centre struck round to
the diameter of 9 inches, then from the centre strike a curve to the
right length round both ends, back and front, taking care that both
riser and tread are properly tongued and grooved; if the tread be
1 in. will require a piece 14 in. by 24 in. fixed on each wide end, top
side of tread, rounded exactly the same as tread, and will form two
reeds, returned at each end, plain inside. The riser fixed on the top
of tread, glued and otherwise fastened, will constitute one step, with
the addition of piece glued, &c. at each end of riser, in the shape of
bracket or truss, according to fancy or fashion, taking care to put a
inch screw bolt through the front corner of treads and risers; the first
step will vary respecting substance, &c. Landings, double the size of

page_text: stops, but the same form; the whole of the structure carefully adjusted;
and according to ground plan; diagrams from 4 to 8, enclosed within
a frame of a triangular form, being tipped with brass at each angle,
No. 8. In addition, fitted a rack and range, as represented, with the
whole of the forms of tubes, &c. .(no glass spirit tubes are claimed as
my Invention, &c.), are consolidated and enclosed in a frame of a
triangular form.
N° 1 to 4 enclose within a frame, as represented, filled in with brass
fittings, tubes, &c.
In witness whereof, I, the said John Mold, have hereunto set
'my hand and scal, this Fifth day of December, in the year
of our Lord One thousand eight hundred and fifty-three.
