such like purposes.
DAVID ROCHE, 50, Ranelagh Road, Ealing, Retired Mariner, do hereby declare the
nature of this invention to be as follows:
This invention consists of a new or improved structure for use for painting, decora-
ting, building and other purposes. The object being to enable a person or persons
using the structure to operate same in the required direction, such operation being
effected from a platform or other suitable arrangement upon which the operator or
operators are carried. In carrying out my invention I provide a base which is carried
upon suitable wheels this base being extensible in the required direction either of its
length or breadth; an extensible structure or frame is pivotted upon this base and
carries at its upper end a platform or stage which is provided with a winch or such like
means for operating blocks and tackle so arranged as to enable the structure to be
swayed or moved upon this surface or base; by this arrangement the required surface
may be operated upon such as when painting, without the necessity of shifting the
whole of the structure, as, by swaying or moving the structure in the required
direction, a fresh surface will be rendered accessible. If desired, the structure inay
be employed as a water tower for use in cases of fire & for purposes where it is
required to deliver water from a height. The frames are so arranged as to enable
them when required to be collapsed or folded up for purposes of transport. Although
I have referred to blocks & tackle, it will be readily understood that any convenient
& well known means for extending the frames may be employed, as the essential
feature of the invention consists in the two structures or frames pivottally attached
to the base aforesaid, and carrying at the upper ends thereof a platforin or stage
which may be moved through the required distance, which will depend upon the
relative position and arrangement of the parts.

page_text: is to be performed, to be particularly described and ascertained in and by the following
statement:
This invention consists of a new or improved structure for use for painting,
decorating, building, and other purposes, the object being to enable a person or
persons using the structure to operate the same in the required direction, such opera-
tion being effected from a platform or other suitable arrangement upon which the
operator or operators are carried.
In carrying out this invention a base is provided which is carried upon suitable
wheels, this base being extensible in the required direction either of its length or
breadth. An extensible structure or frame is pivoted upon this base and carries at
its upper end a platform or stage which is provided with a winch or suchlike means
for operating blocks and tackle so arranged as to enable the structure to be swayed or
moved upon this surface or base. By this arrangement the required surface may be
operated upon, such as when painting, without the necessity of shifting the whole of
the structure, as by swaying or moving the structure in the required direction a fresh
surface will be rendered accessible.
'
The frames are so arranged as to enable them when required to be collapsed or
folded up for purposes of transport. Although blocks and tackle have been referred
to it will be readily understood that any convenient and well-known means for
extending the frames may be employed, as the essential feature of the invention con-
sists in the two structures or frames pivotally attached to the base as aforesaid and
carrying at the upper ends thereof a platform or stage which may be moved through
the required distance which movement will depend upon the relative position and
arrangement of the parts.
If desired the structure may be employed as a water tower for use in cases of fire,
and for purposes where it is required to deliver water from a height.
In the accompanying drawings,
Figure 1 is a side elevation, and
Figure 2 a front elevation showing one method of carrying out this invention.
Like letters indicate like parts throughout the drawings.
The
The platform A upon which the decorator or other operator may stand or sit may
be made of any convenient form and is supported by two extensible or telescopic
limbs each of which comprises upper and lower members B B and C C¹ respectively.
The platform A is provided with brackets A¹ preferably of metal by which the
member B is rigidly secured to one side of the platform A, whilst the member C is
by the same means pivotted at A³ to the other side of the platform A.
limbs B B, C C¹ are supported or carried by a base D having an extensible portion D¹,
and any convenient device D2 is provided by which the extensible portion may be
secured in any position upon the base D. The member B¹ is secured to a frame B2
which, with the member B¹ is pivotted to the base D by pins or other devices E.
The pins E about which the member B1 and frame B2 pivot are, for convenience,
carried by supports or stops F which are preferably rigidly secured to the base D.
The member C¹ is pivotted at E to the extensible portion D₁ of the base D and
stops F1 are provided on either side of the member. The stops F¹ may be of any
The
convenient construction, and are provided with a removable cross bar F2.
members B and C are arranged to slide upon the members B and C, and for this
purpose suitable guides are provided such as B3, C² on the members B¹, C¹ respectively.
These guides may be secured either to the sliding or stationary members and may be
placed in any convenient position upon the same, any desirable number being used.
Braces such as B B and C³ C may be provided to connect and strengthen the
different portions of the members B B and C C¹ respectively. Pulleys or blocks G G¹,
and H H are secured to the braces B B5 and C3 C4. Tackle G, secured by one end
to the base D at D³, is passed through the blocks B4 B and secured at its other end
to the windlass J mounted on the platform A. Tackle H2 is similarly arranged
between the members CC¹ secured to the extensible portion D¹ of the base D at D
passed through the blocks H H¹ and also finally secured to the windlass J.

page_text: The operation of this apparatus is as follows :-
Presuming the apparatus to be in the position shown in the drawings the decorator
or other operator having completed that portion of his work within reach from the
platform A can without descending from the platform move the same so that he is
enabled to reach a fresh portion of his work. To do this it is only necessary to revolve
the drum of the windlass J when it is obvious that if the windlass J is revolved in the
direction of the arrow the tackle G2 will be lengthened, while the tackle H² will be
shortened. This will cause the member C to slide down upon the member C¹ thus
shortening the limb C C on that side of the platform while the member B will slide
up upon the member B₁ thus causing the members B B¹ on the other side of the
platform A to be lengthened. As the limb B B¹ is rigidly secured to the platform A
by the brackets A¹ while the limb C C is pivotted to the same, it is obvious that this
extension of the former limb and contraction of the latter will cause the structure
to cant so that it takes the position indicated by dotted lines. The stops F prevent
the structure from being canted beyond a certain range on the one side and the cross
bar carried by the stops F¹ serves the same purpose when the structure is canted
in the direction referred to above.
•
Although the tackle G2 H2 has been described as two separate cords or ropes each
secured to the base D and windlass J, it is obvious that they may form one rope
secured at each end to the base D and having some intermediate portion of its length
passed several times round the windlass J.
If it is desired to raise or lower the platform A, this may be done by releasing the
tackle G2 H² from the base D and hauling upon it until the platform A is raised the
required height, when the tackle may be again secured at D³ D on the base D. Also
when it is desired to carry the structure from one place to another the tackle G2 and
H2 is released from the base D so that the members B and C slide down to their
lowest position upon the members B¹ C₁; the two limbs are then brought together by
contracting the extensible portion Di of the base D.
To further render the apparatus portable it may be provided with wheels K carried
by bearings K¹ which slide upon the frame B2 and are provided with tackle K². The
base D may thus be raised from the ground by the tackle K2 and the structure
wheeled forward whilst the limbs B B, C C¹ remain in the position described in the
paragraph immediately above. Or the limbs may be lowered into a more or less-
horizontal position towards the stops F1, from which the cross bar F is previously
removed. During the lowering of the limbs into this position the bearings K' slide
forward upon the frame B2. The whole apparatus may then be wheeled forward with
the base D entirely off the ground, or wheels or runners K³ may be provided at that
end of the base D which will be nearest the ground so that that end of the base D.
may if desired run upon the ground. Side extensions L may be provided in the.
base D so that if desired the wheels K may rest upon the said extensions when
the apparatus is in use. These extensions may be arranged to be drawn out and
withdrawn in any convenient manner by operating a common lever or other
device.
If preferred those ends of the tackle G2 H2 which are secured to the base D may be
secured to the platform A by means for instance of a second windlass or other device
so that the user of the apparatus may raise or lower the platform without descending,
from the same in addition to his being able to cant the structure as described.
It will be understood that although the windlass J has been described as mounted
on the upper part of the platform A it might be mounted on a lower platform such
as A3 or in any other position conveniently within reach of the operator; also any
device such as a worm and socket mechanisın or gearing may be used to extend or
contract the members B B, C C in place of the tackle G2 H2. Also any convenient
device such as rack and pinion motion may be arranged if found necessary between
the platform A and the limbs B B¹, CC¹ so that as the lengths of the limbs are
oppositely varied the platform A may always be kept level. Further the apparatus
may be arranged so that the platform A is carried by one limb only pivotted to
the base D, the limb being swung about the pivot at its lower end by means of

page_text: some form of gearing which will also serve to support it. If desired, this single
limb may be provided with a flexible member, such as a chain, connecting its upper
portion to the base D, the said flexible member serving as a tie between the upper
end of the limb and base which carries the limb. Again, instead of causing either
the limb or limbs to cant or swing about pivots upon the base to which they are
secured, the whole structure may be made to rest upon wheels and provided with
gearing operated from the platform A so that the whole structure may be propelled
forward by means of the wheels operated by the said gearing. To do this, the
bearings K¹ of the wheels K may be furnished with some locking device by which
they may be locked to the frame B³, so that when the base D is raised from the
ground by the tackle K2 the weight of the whole structure may fall upon the
wheels K. The gearing referring to can then be arranged to operate the wheels K
and thus to propel the structure as in the manner described. When thus arranged
the wheels K³ would serve to carry the end D¹ of the base D. The construction of
the apparatus described may in fact be considerably varied in detail without
departing from the principle of this invention.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
