SCAFFOLDING USED IN THE ERECTION OF BUILDINGS."

PROVISIONAL SPECIFICATION left by the said Henry Batt at the Office of
the Commissioners of Patents on the 14th February 1876.
HENRY BATT, of Victoria Road, Kentish Town, London, N.W. INROVEMENTS
IN THE CONSTRUCTION OF SCAFFOLDING USED IN THE ERECTION OF BUILDINGS."
My Invention of improvements in scaffolding consists of an arrangement of
standards with connections and moveable shoes, so that the ordinary scaffold poles
and cords are entirely dispensed with. I use for this purpose vertical rectangular
standards of any convenient lengths and set at similar distances apart as scaffold
poles, and on the top of each length I place a double end metal cap, one end passing
over the top of the last length of standard and the other end being open to receivo
the next length. By this means any required height of scaffolding may be erected
by short lengths of standards. Sliding loosely up and down each standard is a
strong metal ring or collar carrying any required number of shoes. The shoes,
which are for the purpose of carrying or supporting ledgers or horizontal bearers,
hook at the tops on to the metal collar, while the under sides are furnished with
sharp spikes or teeth pressing against the standard, and when any weight is put on
to the shoes by the ledgers or scaffold the teeth are forced into the standard, and by
that means the scaffold may be fixed at any required height, and the greater the
weight the firmer the teeth will hold.
Each ring or collar may be made to carry one, two, three, or four shoes as
desired..

page_text: My said Invention relates to the construction of scaffolding, and consists of an
arrangement of standards in combination with connections and adjustable shoes and
links or collars so constructed and arranged that the ordinary scaffold poles, cords,
and wedges usually employed are entirely dispensed with. In carrying out my
Invention I arrange at a suitable distance apart in a similar manner to ordinary
scaffold poles a number of vertical standards, consisting of rectangular or other
suitable shaped beams of wood (fir by preference), on the upper end of each of
which I fit a metal connecting piece containing two sockets, one of which fits on to
the upper end of the lower section of the standard, whilst the other socket receives
the lower end of another length or section when it is required to increase the height
of the scaffolding. By fitting similar connecting pieces or sockets to the upper
ends of each succeeding superposed section the height of the scaffolding may be
increased to any desired extent. The ledgers or horizontal bearers for supporting
the puttocks that carry the scaffold boards are carried in metal shoes suspended by
means of hooks with which they are provided to strong metal rings or collars fitted
to slide freely over the standards. These shoes are provided with sharp points or
teeth, which by the weight of the ledgers or horizontal bearers are caused to
penetrate the standards, and thereby hold the shoes and the ledgers securely in
position, whilst any additional weight placed on the bearers will tend to force the
teeth of the shoes further into the standards, and thereby increase their holding
power.
And in order that my Invention may be clearly understood I have annexed to
this my Specification a Sheet of explanatory Drawings, in which the same letters
of reference are employed to indicate corresponding parts in all the Figures.
Figure 1 is an elevation of a portion of a standard having fitted thereto a con-
necting or socket piece and two shoes constructed according to my Invention.
Figure 2 is a horizontal section of a standard fitted with four shoes.
Figure 3 is a vertical section of one of the connecting or socket pieces.
Figure 4 is a plan of the same; and Figure 5, a plan of one of the shoes
detached.
A represents a portion of one of the sections of a standard, to the upper end of
which is fitted a metal connecting or socket piece B provided with an internal
flange C dividing it into two sockets D, E, for the reception respectively of the
upper end of the section A and the lower end of a superposed section F of the
standard.
The height of the scaffold may be increased to any desired extent by fitting to
the upper end of each superposed section a similar connecting or socket piece for
the reception of the ends of additional sections of the standard. G is a metal
collar or ring fitted to slide freely up and down the standard, to which rings the
shoes H are suspended by the hooks I. These shoes carry the bearers for supporting
the puttocks that carry the scaffold boards, and are provided with teeth K on their
under side, which by the weight of the ledgers and scaffold boards are forced into
or caused to enter the standards, the shoes being thereby prevented from shifting
out of position. Any increase of weight placed on the shoes will tend to force the
teeth further into the standards, and will consequently increase their holding
power.
prefer to make the standards of a retangular section, as shewn in my Drawings,
but they may be cylindrical, hexagonal, triangular, or of any other suitable shape.
Each of the rings G may carry any desired number of shoes, according to the
character of the scaffold to be erected.
Having now described the nature of my said Invention and the mode of carrying
the same into practical effect, I wish it to be understood that what I claim as my
Invention is,―
First. The application and use in substitution for ordinary scaffold poles of
standards consisting of lengths or sections of wood joined together by metal con-
necting pieces, substantially as and for the purpose herein-before described and
illustrated by my Drawing.

page_text: Secondly. Supporting the ledgers or horizontal bearers in adjustable metal shoes
provided with spikes or teeth for the purpose of fixing the said shoes and bearers at
any desired elevation upon the vertical standards with links or collars, substantially
in the manner herein-before described and illustrated by my Drawing.
In witness whereof, I, the said Henry Batt, have hereunto set my hand and
scal, this Fourteenth day of August, in the year of our Lord One thousand
eight hundred and seventy-six.
