PROVISIONAL SPECIFICATION left by the said William Edwin Heath at the
Office of the Commissioners of Patents on the 29th December 1883.
WILLIAM EDWIN HEATH of 176 Camden Road in the County of Middlesex
"IMPROVEMENTS IN THE METHOD OF SECURING OR SHORING UP DANGEROUS
STRUCTURES AND FOR OTHER PURPOSES
"
This invention has for its object improvements for securing or shoring up
dangerous structures and for other purposes by means of shores commonly known
as raking shores and for sustaining framework of any kind of slight construction
and for shores for ship building.
I provide a foot piece of very strong proportions which I call the base of the
triangle one end of which is inserted or stubbed into the base of the building
or erection, and the other end projecting the requisite length from the base of the
structure or framework, is hollowed or recessed to receive the foot of the raking
shore.
The upper end of this raking Shore which is placed leaning on the building or
erection to be shored is fitted to receive a vertical rod of Iron flat or round or a
chain with an eye or eyes through which a bolt passes resting in a transverse
groove on the upper end of the raking shore which rod passes downwards through
or outside the leaning or raking shore in such a manner as to enable a set of rods
of Iron or other material or a continuous rod to be carried down to the foot piece
as close as possible to the base or foot of the wall or structure to be secured.
This rod or flat bar is then at its lower end secured by a bolt transversely to the
inner underside of the foot piece or base of the triangle in such a manner as to
connect by an Iron tie the apex of the raking shore with the foot piece or base.
I then by means of a swivel screw and with or without wedges exert a strain on
this tie rod and by bringing the foot piece and the apex of the raking shore tightly
together exert a straining force on the face of the wall buildings or structure which
077

page_text: tends to prevent the fall or the deviation from the perpendicular of either-without
the rupture of the tie rod.-the shores or foot pieces may be either timber or
timber shod with metal or wholly of metal and the foot piece may be inserted in
the brickwork of the base of the wall or at any height or may be packed as the case
of a shop front by the introduction of an intermediate packing under the brest
summer or in case of windows by a similar packing.
But I claim the invention of a metal or other tie rod from the foot piece to or
near the apex of the raking shore and the means of creating a tension on this tie
rod by a screw working in a swivel drawing the two points together and thus
exercising a pressure on the surface of the wall or structure to be supported.
For convenience of fitting and adapting to lengths I make the tie rod in several
lengths or parts connected by bolts or pins.

an Order of the Lord Chancellor filed by the said William Edwin Heath in

"IMPROVEMENTS IN THE METHOD OF SECURING AND SHORING UP DANGEROUS
STRUCTURES AND FOR OTHER PURPOSES
"
This Invention has for its object improvements for securing or shoring up
dangerous structures and for other purposes by means of shores commonly known
as raking shores and for sustaining framework of any kind and for scaffolding ship-
building and other purposes of a like nature or for platforms for steam derricks and
cranes.
I provide a foot piece of strong proportions which I call the base of the triangle
fig: 1 one end of which is to be inserted into the wall or structure to be shored or
into the base of the framework or at any height, and the other and projecting
horizontally to any required distance from the base of the structure or framework
to receive the foot of the raking shore.
The raking shore fig: 2 is then placed in position against the building or erection
to be shored: The upper end of the raking shore fig: 3 is so fitted as to receive a
vertical iron or metal rod chain or wire or other rope fig: 4 through which a bolt
passes horizontally which bolt may rest on a cleat or in a groove or be bolted to
the shore, the rod chain or rope passes downwards through or outside the raking
shore fig 2 in such a manner as to enable a set of rods chains or wire rope or a
continuous rod to be carried through or below the foot piece fig: 1 as close as
possible to the base of the structure to be shored.
This rod or other contrivance is then secured to the foot piece which enters the
wall or base of the structure, by a transverse bolt fig: 5 as near the inner end as
possible and in such a manner as to connect by an iron or other tie to the apex of
the shore with the base fig: 1. I provide a screw swivel piece fig 6 which I insert
in any position on the tie rod and by turning this swivel shorten the rod and bring
a strain to bear on the apex of the shore and consequently on the face of the
building to be shored, which tends to prevent the fall outwards of the building
unless the tie rod is ruptured or broken.-The shores and foot piece may be of
timber or timber and metal or wholly of metal and the foot piece may be inserted
at any height in the building or in case of an opening or shop front packed up
under the beam or brestsummer with an upright timber in cases where the foot
piece cannot be used I attach the tie rod to a bolt through the wall fig: C or by
another way fig: D get the strain on the tie rod requisite for resisting the fall of
the building. The face of the shoring by fixing cleats at intervals fig: E will form
a ladder and scaffolding may be affixed to the shoring for cornices or other work by
stepping on to one of the divisions in the shoring and carrying upwards a timber
with a cross piece to bear scaffold boards fig: E. This appliance can also be used
for underpinning instead of the plan of needling as now adapted.
Having now described the nature of my invention what I claim and desire to
have secured to me by Letters Patent is :
The invention of the tie rod rope or chain from the apex of the shore to the base
of the building and the manner of creating the tension on the tie by a swivel screw
drawing the two points together and thus exercising a pressure on the vertical

page_text: surface of the wall or structure to be supported, for convenience of fitting I make
the tie in several lengths fig: 9 or in one length. Drawings A and B shew single
and double shoring.
In Witness whereof I the said William Edwin Heath have hereunto set my
hand and seal this third day of July One thousand eight hundred and eighty four.
