Year: 1875

page_text: LETTERS PATENT to John Yeadon, of Idle, near Leeds, in the
County of York, for the Invention of “IMPROVEMENTS IN THE MEANS
OR APPARATUS FOR FIXING AND SUPPORTING 'SCAFFOLDING,' PART OF WHICH
PROVISIONAL SPECIFICATION left by the said John Yeadon at the
Office of the Commissioners of Patents, with his Petition, on the
25th May 1875.
I, JOHN YEADON, of Idle, near Leeds, in the County of York, do
hereby declare the nature of the said Invention for "IMPROVEMENTS IN
THE MEANS OR APPARATUS FOR FIXING AND. SUPPORTING SCAFFOLDING,' PART OF
WHICH INVENTION IS ALSO APPLICABLE FOR RAISING MATERIAL ON TO THE SAME," to
be as follows:-
My Invention consists of a means or apparatus whereby I dispense
with the ropes usually employed for securing the poles and supporting
the planks and other parts of scaffolding, also provides a ready means
for raising material on to the scaffolding.

page_text: The arrangement is not only applicable to ordinary buildings, but is
also for ascending the exterior of tall chimneys for repairs or building
purposes.
My apparatus consists of a rectangular bearing or bracket. To the
upper part of its vertical side is provided a clip or collar, which is made
to clasp the pole. At the lower end of the vertical side of the bracket
is provided an adjustable saddle, which is made to rest upon the pole.
The saddle is made adjustable to suit the taper of the pole. On the top
of the rectangular bracket is provided a suitable holder or holders for
the various horizontal pieces or timbers required in the erection of
scaffolding. In whatever position this rectangular bracket is placed on
the scaffold pole there it remains, and the greater the weight placed on
the top of the bracket the firmer it adheres to its position. Light
rectangular brackets may be attached to the feet whereby a man may
ascend a pole with perfect safety, and stop at any required position.
When required for hoisting, in combination with the above-described
rectangular bracket, blocks of ordinary construction may be employed,
provision being made thereon for attaching the same.
When required for fixing scaffolding for the purpose of ascending
buildings or repairing tall chimneys the brackets are of a similar con-
struction to those herein-before described, but the clip or collar is
constructed to suit the shape or construction of the chimney or stack,
so also is the adjustable saddle at the lower extremity of the vertical
side of the bracket or bearing.
SPECIFICATION in pursuance of the conditions of the Letters Patent, 25
filed by the said John Yeadon in the Great Seal Patent Office
on the 25th November 1875.
TO ALL TO WHOM THESE PRESENTS SHALL COME, I, JOHN
YEADON, of Idle, near Leeds, in the County of York, send greeting.
WHEREAS Her most Excellent Majesty Queen Victoria, by Her 30
Letters Patent, bearing date the Twenty-fifth day of May, in the year of
our Lord One thousand eight hundred and seventy-five, in the thirty-
eighth year of Her reign, did, for Herself, Her heirs and successors,

page_text: give and grant unto me, the said John Yeadon, Her special licence, that
I, the said John Yeadon, my executors, administrators, and assigns, or
such others as I, thesaid John Yeadon, my executors, administrators,
and assigns, should at any time 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 "IMPROVEMENTS IN THE MEANS OR APPARATUS
FOR FIXING AND SUPPORTING SCAFFOLDING, PART OF WHICH INVENTION IS ALSO
APPLICABLE FOR RAISING MATERIAL ON TO THE SAME," upon the condition
(amongst others) that I, the said John Yeadon, my executors or admini-
strators, by an instrument in writing under my, or their, or one of their
hands and seals, should particularly describe and ascertain the nature of
the said Invention, and in what manner the same was to be performed,
and cause the same to be filed in the Great Seal Patent Office within
six calendar months next and immediately after the date of the said
Letters Patent.
NOW KNOW YE, that I, the said John Yeadon, 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 accompanying two Sheets
of Drawings and marks thereon, that is to say :-
My Invention consists of a means or apparatus whereby I dispense
with the ropes usually employed for securing the poles, and supporting
the planks and other parts of scaffolding, also provides a ready means
for raising material on to the scaffolding.
The arrangement is not only applicable to ordinary buildings, but is
also for ascending the exterior of tall chimneys for repairs or building
purposes.
My apparatus consists of a rectangular bearing or bracket. To the
upper part of its vertical side is provided a clip or collar, which is made
to clasp the pole. At the lower end of the vertical side of the bracket
is provided an adjustable saddle, which is made to rest upon the pole.
The saddle is made adjustable to suit the taper of the pole. On the top
of the rectangular bracket is provided a suitable holder or holders for
the various horizontal pieces or timbers required in the erection of
scaffolding. In whatever position this rectangular bracket is placed on

page_text: The arrangement is similar to the herein-before described, except that
the rectangular bearing or bracket j is arranged to receive a square or
oblong piece of timber, as shewn at k; also the collar & is made in the
form of a hook instead of having a hinged clip. The set screw mis
employed for keeping the timber in position, as shewn.
The arrangement is similar to the nerein-belore described, except thAT
the rectangular bearing or bracket jis arranged to receive a square or
oblong piece of timber, as shewn at k; also the collar is made in the
form of a hook instead of having a hinged clip. The set screw mis
employed for keeping the timber in position, as shewn.
Figures 6 and 7 are of a similar construction to Figures 4 and 5,
except that it is provided with a hinged clip n similar to that shewn in
Figures 1 and 2.
A further modification of my Invention is shown at Figures 8 and 9,
being respectively an elevation and plan.
Instead of forming, the upper part of the bracket or bearing in the
manner shewn at Figures 1, 4, and 6 I construct it with an angular
form, as shown at o. In this case I, by preference, employ the hinged
clip p, and dispense with the adjusting at the lower end of the vertical
side q; r shews the mode in which the horizontal timber rests between
the vertical scaffold poles and bracket o. When this arrangement is
employed for supporting the ends of the vertical scaffold poles I employ
a cup t, as shewn at Figures 10 and 11, which are respectively an
elevation and plan of the same. In this arrangement it will be seen
that the scaffold pole is intended for increasing the height of the
scaffold, and is supported on the bracket v, and retained in position by
the cup t.
'
Instead of employing the hinged clip, as shewn in Figures 8, 9, 10,
and 11, I employ a chain w, which may be carried any number of times
round the pole and tightened, or one alone round the pole, as shewn at
Figures 12, 13, and 14. By this arrangement not only may the vertical
scaffold poles be secured together, as shewn in Figure 12, but also the
bracket, which may be of a similar construction to those shewn in
Figures 8 and 10, may be employed for supporting the horizontal beams,
or poles, or scaffolding.
Another application of chain arrangement is shewn at Figures 15, 16,
and 17, respectively a front elevation, a side elevation, and plan looking
at the top. In this arrangement the chain y is put slackly on the poles,
after which the horizontal pole a' is threaded through the chain, as
shewn. To the chain y is attached the collar 6', which may when
required be provided with spikes o³, as shewn at Figures 15 and 17. It will

page_text: be readily understood that (the weight of the pole a' tightens the chainy,
and causes the clip b' to press so hard upon the surface of the pole that it
keeps itself in one position, and supporting the scaffold pole a¹ by means
of the chain y. The heavier the weight put upon the horizontal pole or
timber a' the more securely it is held. When preferred the brackets,
shewn at Figures 10 and 11, may be employed instead of the collar 6',
and the chain y may be passed round the pole any required number of
times.
I have shown at Figure 18 a means whereby a man provided with
brackets similar to those shown at Figures 4 and 5, with a slight
alteration in the top thereof to receive the feet, can ascend a pole or
other vertical column.
Sheet 2 shews a modification of my Invention, and the means of
employing it for raising materials on to the scaffolding or other places.
Figure 1 is a side elevation; and Figure 2, a plan looking at
the top.
It will be readily understood that the jib a and tee rods 6 form a
rectangular bracket. In this case I have shewn the chain c, which I
employ instead of the clips or collars, shewn on Sheet 1. At d and e I
have shewn the lower part of the rectangular bracket held to the pole f
by means of similar chains d and e. A block or crane of ordinary con-
struction may be applied to this arrangement of rectangular bracket for
hoisting purposes. The greater the weight placed upon it at 9 the
firmer it is secured to the pole at c, d, and e.
In all cases when preferred spikes may be employed within the clip or
collar, as shewn at ď³, Figure 2, Sheet 1.
Having now described the nature of my said Invention, and shewn
by Drawings how the same may be carried into practice, I would have it
understood that I do not limit myself to the exact limits, details, or con-
figuration of the various parts I have explained and shewn, as the same 3
may be varied or modified without in any way departing from the naturo
of my Invention; but what I do claim and desire to be secured to me
by Letters Patent is,―
First. The arrangement, construction, and application of the various
forms of apparatus for fixing and supporting scaffolding, substantially as 3

page_text: Second, The arrangement, construction, and application of apparatus
for raising material, substantially as herein set forth.
In witness whereof, I, the said John Yeadon, have hereunto set
my hand and seal, this Twenty-third day of November, in the
year of our Lord One thousand eight hundred and seventy-
five.
