Improvements relating to Removable Scaffolding.
I FREDERICK WILLIAM GOLBY of 36 Chancery Lane, in the County of
Middlesex, Patent Agent, do hereby declare the nature of this invention, as
communicated to me by Mads Kruse of Copenhagen, in the Kingdom of Denmark,
Master Painter, to be as follows:-
The invention relates to improvements in removeable scaffolding and its chief
object is, to render the up and down movement of the box as easy, convenient and
safe as possible.
In the accompanying drawings
Figure 1 shews the improved scaffolding as seen from the front.
Figure 2 is a side elevation of same, partly in section; and Figure 3 is a detail
plan view.
The scaffolding consists of a box a which can be moved up and down along the
pillar which is provided in front with a guide rail; in the latter at suitable
distances apart are holes for the hooks by means of which the box is hung up.
To avoid dragging, the box a is furnished with friction rollers k which during
the up and down movement roll along the pillar b.
At the top the pillar has two sloping arms v provided with rolls w these rolls
rest against the wall of the building and roll along the latter, when the scaffolding
is moved sideways.
Above the arms is a head r which acts round the stretching steering rope y
which is gripped and checked by the two toothed sectors s; the latter are
controlled by spiral springs which are connected to the rope in such a way, that
the grip or check on the steering rope ceases, if this rope is pulled. At the top in
front the pillar has an arm u with a block for the ropes p. If the pillar is to be
moved to either side, one must first pull the rope t to release the grip of the
sectors s from the rope q so that the latter is no longer kept in the head then one
of the ropes p is slackened and the other pulled, viz. :--that one, which is on the
side one wants to bring the pillar to. The foot of the pillar is moved on successively
hy means of hand spikes.
When the pillar has been removed to the desired spot the rope p is fastened
again and rope t loosened. The spiral spring will then cause the toothed sectors s
to again grip the running rope y in the head r. The box has behind the pillar a
falling board or bridge which can be let down in a horizontal direction, where it
is kept by means of chains m (see Figure 2).
Between the bridge and the wall is a sail cloth channel o, fastened on two
removable bolts n; this channel is for the reception of dirt, water etc.
The box is, as before said, hung up by two hooks e and y, of which the lower
one e can be turned round a cross bolt in connection with the bottom of the box,
The cross bolt is firmly united to two vertical poles c, at the upper ends of which
the ends of the handles are pivotted. The handles are also pivoted to one peg
sitting in a mounting which carries above the pivot of the upper hook f and is
provided below with a panel on which is supported the spiral spring which
presses the hook f against the pillar band with a coupling box which glides along
the steering pole and is connected with the bottom of the box. The hook e is
pressed against the pillar 6 by the spiral spring g when the latter is in the stretched
position, shewn in full lines in Figure 2.

page_text: If the box a is to be raised on the pillar b, the two handles d must first be
brought from the lower into the higher position (see Figure 1). The handles
then turn round the pivots in the poles c and the book is brought into the next
hole above, whilst the hook e and the box remain in the original position.
If now, the handles d are pressed down again, they turn round their common
pivot; the consequence is, that the hook e is brought into the next hole above and
the box a is now lifted a distance equal to the distance between two consecutive
holes in the pillar b.
The hook is connected, so that it can be turned, with the angular piece i,
which is pivotted at j (see Figure 2). The spring y can be fixed in two different
positions on the angular piece i, the position shewn drawn in full lines in Figure 2
is used to lift the box or to keep it in position when resting; whilst the position
shewn by the dotted lines is used to lower the box. In the latter position the
spring g is so much compressed, that it pushes the hook e out of the holes in the
pillar which however cannot be done, until the hook has been raised sufficiently to
clear the hole. To let the box down, the handles d are first moved, till the
compressed spring g can press the hook e back. The box a will then siuk with the
hook e, until the latter is pressed by the now stretched spring g into the next hole
below. And the spring pulls at the same time at the angular piece i. The pull
will, when the hook has been freed of the hole of the pillar by means of the
handles, overcome the spring h, and bring the hook to the next hole below, into
which it is pressed through spring h, which is now again supported by the
compressed spring g.

Improvements relating to Removable Scaffolding.
1 FREDERICK WILLIAM GOLBY of 36 Chancery Lane, in the County of
Middlesex, Patent Agent, do hereby declare the nature of this invention as
communicated to me by Mads Kruse of Copenhagen, in the Kingdom of Denmark,
Master Painter, and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement :-
The invention relates to improvements in removable scaffolding, and its chief
object is to render the up and down movement of the box as easy, convenient and
safe as possible.
In the drawings left with the Provisional Specification
Fig. 1 shews the improved scaffolding as seen from the front.
Fig. 2 is a side elevation of the same partly in section and
Fig. 3 is a detail plan view.
The scaffolding consists of a box "a" which can be moved up and down along
the pillar b, which is provided in front with a guide rail; in the latter at suitable
distances apart are holes for the hooks by means of which the box is hung up.
To avoid dragging, the box a is furnished with friction rollers k which during
the up and down movement roll along the pillar b.
At the top the pillar has two sloping arms provided with rolls w these rolls
rest against the wall of the buildings and roll along the latter, when the scaffolding
is moved sideways.
Above the arms is a head r which acts round the stretching steering rope g which
is gripped and checked by the two tooth sectors & the latter are controlled by
spiral springs, which are connected to the rope t in such a way, that the grip or
check on the steering rope ceases, if this rope is pulled. At the top in front the

page_text: pillar has an arm u with a block for the ropеь p. If the pillar is to be moved to
either side, one must first pull the rope t to release the grip of the sectors & from
the rope so that the latter is no longer kept in the head r then one of the ropes p
is slackened and the other pulled, v. :-that one which is on the side one wants to
bing the pillar to. The foot of the pillar is moved on successively by means of
band spikes z.
When the pillar has been removed to the desired spot, the rope p is fastened
again and rope t loosened.
The spiral spring will then cause the toothed sectors to again grip the running
rope g in the head r. The box has behind the pillar a falling board or bridge
which can be let down in a horizontal direction, where it is kept by means of
chains m (see Figure 2).
Between the bridge and the wall is a sail cloth channel o, fastened on two
removable bolts n; this channel is for the reception of dirt water etc.
The box is, as before said, hung up by two hooks e and f, of which the lower
one e can be turned round a cross bolt in connection with the bottom of the box.
The cross bolt is firmly united to two vertical poles c at the upper ends of which
the ends of the handles d are pivotted. The handles are also pivotted to one peg
sitting in a mounting which comes above the pivot of the upper hook ƒ and is
provided below with a panel on which is supported the spiral spring
which presses
the hook against the pillar band with a coupling box which glides along the
steering pole and is connected with the bottom of the box. The hook e is pressed
against the pillar b by the spiral spring when the latter is in the stretched
position shewn in full lines in Fig. 2.
If the box a is to be raised on the pillar b the two handles d must first be brought
from the lower into the higher position (see Fig. 1).
The handles then turn round the pivots in the poles c and the hook is brought
into the next hole above whilst the hook e and the box remain in the original
position.
If, now the handles d are pressed down again, they turn round their common
pivot; the consequence is, that the hook e is brought into the next hole above and
the box a is now lifted a distance equal to the distance between two consecutive
holes in the pillar b.
The hook is connecter, so that it can be turned with the angular piece i which
is pivotted at j (see Fig. 2). The spring y can be fixed in two different positions
on the angular piece i, the position shewn in full lines in Fig. 2 is used, to lift the
box or to keep it in position when resting whilst the position shewn by the dotted
lines, is used to lower the box. In the latter position the spring g is so much
compressed, that it pushes the hook e out of the holes in the pillar, which however
cannot be done until the hook has been raised sufficiently to clear the hole. To
let the box down, the handles d are first moved till the compressed spring g can
press the hook e back. The box a will then sink with the hook e until the latter
is pressed by the now stretched spring g into the next hole below. And the
spring pulls at the same time at the angular piece i. The pull will when the
hook has been freed of the hole of the pillar by means of the handles, overcome
the spring and bring the hook f to the next hole below, into which it is pressed
through spring which is now again supported by the compressed spring g.
Having now particularly described and ascertained the nature of this said
invention and in what manner the same is to be performed I declare that what I
claim is
-
1. A removable scaffolding such as above described chiefly characterised by the
hooks e and f, which fit into holes on or in the pillar and are controlled by the
springs g and hand connected with the movable box a; and by the two handles d
which have one common and two seperate turning points and lastly by the head r,
with the special checking system for the running rope y substantially as hereinbefore
set forth and illustrated in the drawings.

page_text: 2. A removable scaffolding constructed and operating, substantially in the
manner described and illustrated, and for the purpose stated.
