PROVISIONAL SPECIFICATION.
Improved Appliances for Building Monolithic Concrete Walls:
I, THOMAS POTTER of Grange Park, Alresford, Hants Clerk of Works do
hereby declare the nature of this invention to be as follows :-
:―
I employ standards or guides of angle iron or steel, rivetted together, and with
a pad of wood, or metal, between, and through this pad I pass flat bars of iron or
steel called wall guages, and which have a series of holes therein. I also use wall
cramps made of bar iron with holes at each end through which I pass bolts having
a series of pin holes to regulate the thickness of the intended walls. I also use
angle or other iron stays or struts to keep the standards or guides in position. I
form angles of walls with wood, fixed to the standards with iron wedge clips.

COMPLETE SPECIFICATION.
Improved Appliances for Building Monolithic Concrete Walls.
I, THOMAS POTTER, of Grange Park, Alresford, in the County of Hants,
Clerk of Works, 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 :-
My invention relates to improvements in appliances used for building concrete
monolithic walls, and consists of the use of standards, or uprights, nine feet in
height, or more or less, as may be found convenient, made of angle iron or steel,
rivetted together, and with a pad of wood between.
These standards are connected together by flat bars of iron or steel, having a
shoulder at one end, and a series of holes in their length at equal distances apart,
and called "wall guages." In practice, the wall guages are passed through
mortices made in the wood pad of the standards, and secured to the latter by means
of bolts and nuts, or iron pins. The standards act as guides for holding in position
rough wood boards for forming a trough into which the concrete is deposited in a
soft state. The boards are held rigidly together at various points by iron wall
cramps of a peculiar form, and having holes therein at fixed distances apart, into
which iron pegs or pins are placed, and which regulate the thickness of the wall to
be built. In practice the standards being placed upright on the ground, are fixed,
or stayed, in that position by means of angle iron stays; the boards are placed in
between, and resting against, the flanges of the standards, and the wall cramps are
secured to the boards and fastened together by means of the iron pins. To secure
the boards more rigidly to the standards, I use clips and wedges made of iron or
steel. In order that my invention may be fully understood, I have shown a plan
and elevation of my improved appliances when fixed ready for use, and I also show
the various parts of the said improved appliances as follows:-
A. A. the standards; B, wall cramps; B1 a part elevation of wall cramp to a
larger scale, showing the hole through which the loose portion C. passes to con-
nect B. B together in pairs; B 2 part side elevations of the same wall cramp B ;
B3 and E sections of the wall cramps B, (either of which are adapted for the
purpose); D.D. wall guages, with a series of pin holes therein to regulate the
thickness of the intended wall; G, iron wedge to connect the iron clip H to
the angle iron fastener K, which is secured to the board and also to the
standards.

I do not claim as a novelty the use of wood boards to form troughs, the same
having been previously invented.
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. Steel or iron standards with a wood pad in the centre, substantially as
described, and of the sections shown on drawing, and marked A, and used in the
way described.
2nd. Steel or iron wall cramps, substantially as described, and shown by section
and elevations B. B. B. B and C.
3rd. Iron or steel wedges and clips substantially as described and shown by
drawings G. H. and K.
