Lake, & Co., Patent Agents, Southampton Buildings, London, for
the Invention of "IMPROVED APPARATUS FOR CONNECTING AND SECURING
SCAFFOLD POLES."-A communication from abroad by Louis Auguste

Sealed the 21st August 1875, and dated the 20th March 1875.
PROVISIONAL SPECIFICATION left by the said William Robert Lake
at the Office of the Commissioners of Patents, with his Petition,
on the 20th March 1875.
I, WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, & Co.,
Patent Agents, Southampton Buildings, London, do hereby declare the
nature of the said Invention for "IMPROVED APPARATUS FOR CONNECTING
AND SECURING SCAFFOLD POLES," a communication, to be as follows:-
It is well known that in erecting scaffolding for the construction of
houses it is the practice to use vertical poles or uprights and horizontal
poles, and on the latter the boards are placed,

page_text: Heretofore the attachment of the horizontal poles to the uprights at
their points of contact has commonly been effected by means of cords.
But according to this Invention I replace these cords by a device
which is very simple, and which possesses the following advantages,
namely,-

page_text: extremity of this screw rod is made square to permit it to be operated
by a key; fis the nut fitted upon the rod d; g, g, are the hooks formed
upon the said nut; is the binding chain.
SPECIFICATION in pursuance of the conditions of the Letters Patent,
filed by the said William Robert Lake in the Great Seal Patent
Office on the 15th September 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM

agree with and no others, from time to time and at all times thereafter
during the term therein expressed, should and lawfully might make, use,
exercise, and vend, within the United Kingdom of Great Britain and
Ireland, the Channel Islands, and Isle of Man, an Invention for "IM-
PROVED APPARATUS FOR CONNECTING AND SECURING SCAFFOLD POLES," a commu-
nication to me from abroad by Louis Auguste Bouilliant, of Paris,
France, Builder, upon the condition (amongst others) that I, the said
William Robert Lake, my executors or administrators, by an instru-
ment in writing under my, or their, or one of their hands and seals,

page_text: Figure 1 is a side elevation illustrating this improved attachment;
Figure 2 is a front view of the same; Figure 3 is a plan of the above
described apparatus. Like letters indicate the same parts throughout
the Drawing.
a is one of the uprights of the scaffolding; b is one of the horizontal
poles of the same; c is the plate, block, or shoe resting against the
upright a; d is the screw rod capable of turning in its place in the
plate c, and formed with a square or polygonal part at e to permit of its
operation by a key or spanner; f is the screw nut or socket fitted upon
the rod d; g, g, are hooks formed upon the said nut or socket; h is the
binding chain.
It is obvious that I may modify the construction or form of the
various parts composing the aforesaid apparatus.
Having thus fully described the said Invention as communicated to
me by my foreign correspondent, and the manner of performing the same,
I wish it understood that I claim, the combination of the plate block or
foot c, the nut or socket with its hooks or wings, the screw rod d, and

scaffolding, as herein-above set forth.
In witness whereof, I, the said William Robert Lake, have here-
