Improvements in Adjustable Cradles or Staging for Use in
Decorating Buildings, and for other purposes.
I, HENRY HARRIS LAKE, of the Firm of Haseltine, Lake & Co., Patent Agents,
45, Southampton Buildings, in the County of Middlesex, do hereby declare the
nature of this invention and in what manner the same is to be performed, to be
particularly described and ascertained in and by the following statement:
-
This invention relates to a stand or chair for the use of artisans employed on or
about the outer wall of a building and it consists in means for the attachment
of the stand or chair to the building and also in means for moving the chair both
towards and from the wall lengthwise and perpendicularly with respect to it,
which means are connected with the chair or stand and adapted to be operated
from it in any of its positions.
Referring to the accompanying drawings;
Figure 1 is a view showing in front elevation my invention applied to a
building.
Figure 2 is a similar view in side elevation.
Figure 3 is an enlarged view in perspective, of an adjustable holder, to which
reference will hereinafter be made.
A represents the chair or stand. It may be of any desired size and of any
form of construction. In the drawings I have represented it as small and adapted
to hold a single person. I have also represented it as consisting of a base-
piece a, which serves as a floor or support and which preferably has a front
edge a¹, which is straight or parallel with the wall of the building, and a curved
side and rear edge a². It is also represented as suspended by the three chains a³,
a, ab, two of which chains a³, a, are attached to the front corners, and the

end are attached to a common uniting block as, and this block has a hook a⁹,
which hooks into the eye or shackle 6 of a block B, connected by a suspending
and hoisting rope 61 with a block B¹, suspended from a trolley C, which is sus-
pended from a horizontal rail D.
The hoisting rope runs through sheaves in the two blocks B, B₁, and its end
is attached to the chair or stand, and it affords means for the raising, holding, and
lowering of the chair or stand by the occupant of the chair.
The rail D is preferably of flat bar iron and is held by the hooks D', D₁ which
are of a size to hook over the gutter or edge of a roof of a building, with which
roof the points engage. Each hook has a long downwardly-extending shank d,
which has extending through its lower end a narrow recess of a size to receive
an end of the rail D, which passes through the said recess d¹ and has a removable

page_text: stop upon its outer end. There is also attached to the lower end of such
shank a screw stay-rod E, having a threaded section c, adapted to turn in a
threaded nut el on the shank, to adjust the position of the lower end of the shank
with respect to the wall of the building. The said stay-rod has its inner ends
provided with pointed forks e, e which are horizontally disposed in relation
to each other and which bear against the wall of the building and act to stay
the lower end of the hook-shank, (see Figure 2). A locking-screw e, carried by
the shank, serves to lock the shank to the screw stay-rod after. the rod has been
adjusted, and the stay-rod also carries at its outer end an adjustable collar e which
may screw upon the stay-rod or otherwise be horizontally movable thereon and
which upon the adjustment of the stay-rod is moved against the outer edge of
the hook-shank and locked against it by a locking-screw e6 (Figure 2). These
suspending-hooks D1, D2, are arranged at some distance apárt and near the ends
of the rail D. When required, an additional reinforcing-hook 13. may be used.
This hook is adapted to be movable between the fixed hooks D', Ds and engages
the rail by means of a hook d³, formed on its lower end and upon which the
rail rests. The rail also carries, near each of the fixed hooks, preferably near
each end, the adjustable blocks FF, each of which is arranged to slide upon the
rail and each of which is adapted to be fastened to the rail by a fastening-
screw f. Each of these blocks has suspended from it beneath the rail a roll f¹,
over which a draw-rope f, extending in both directions from the trolley C and
to the stand or chain A, runs. This rope extends through eyes f³ on the chair
or stand and is long enough to extend to the ground, the chair riding upon it,
and the portion of the rope beneath the chair or stand is prevented from twisting
by means of a weighted separating arm f, having eyes fo through which the rope
runs, and which separates the rope, and a weight f, attached to its centre. The
rope is thus brought to a position to permit the occupant of the chair or stand
to use it in drawing the trolley C and moving the chair or stand horizontally
along the wall of the building in one direction or the other, according to which
branch of the rope is pulled. The chair also has attached to it horizontal
rods G, G, each carrying at its inner end a roll g, adapted to bear against the
wall of the building. These rods are adjustably secured to the chair or stand to
permit it to be set in or out with respect to the said will, and for this purpose
the base a of the chair carries on its under side the rod-holders g', in which the
rods are adjustable and to which they are fastened in fixed position by a set
screw. These rod-holders are near the sides of the chair or stand, and the rods
are thus so located as to prevent the chair or stand from twisting or turning on
its supporting-rope.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, as communicated to me
by my foreign correspondent, I declare that what I claim is :-
1. In a device of the character specified the combination of the rail D; its
supporting-hooks D¹, D3, the trolley C mounted upon said rail, the stand or
chair A, the hoisting, supporting and lowering rope b¹ connecting the chair or
stand with the trolley, the rolls f' adjustably secured to the rail, and the draw-
rope extending from the trolley Cover the rolls and thence to the chair A,
us and for the purposes described.
2. The combination in a device of the character specified of the chair or
stand A suspended from the rail D vertically and horizontally movable in relation
thereto, and the rail supports or hooks D1, D2 having depending shanks provided
with holes for receiving the ends of the rails, and the stay-rods E having an
adjustable relation to the ends of the hook-shanks and also having their inner
ends forked, as and for the purposes set forth.
3. The combination in a device of the character specified of the rail D, the chair
or stand A suspended from a trolley thereon and vertically movable with relation
thereto, the rolls f' and a draw-rope extending over said rolls to said trolley,

page_text: and also extending through eyes in the said stand or chair to a position below the
same, the said rope being endless, and a weighted separating arm through which
said rope extends to prevent the twisting thereof.
4. In a device of the character specified the chair A comprising the base a,
the flexible hangers a³, a³, a', the block a to which the upper ends of said
flexible hangers are connected, and the adjustable bracing-frame a³, substantially
as described.
5. In a device of the character specified the combination of the hooks D1, D2,
the rail D attached to said hooks, the adjustable forked staying-rods E, the
trolley C mounted upon the rail, the adjustable rolls f¹ mounted upon the rail,
the chair or stand A, the hoisting supporting and lowering rope 6¹ connecting
the chair with the trolley, the trolley-rope f extending from the trolley over
said rolls f¹ to the chair and the horizontally adjustable rods G carried by said
chair or stand.
6. An adjustable stand or chair for artisans substantially as shown and
described.
