Improvements in Means for Raising and Suspending.
We, ROBERT BELL, M.D., of Glenae, Aimisfield, near Dumfries, in the County
of Dumfries, and ROBERT MAGUIRE, of 4, Wellfield Street, Springburn, in the
County of the City of Glasgow, Engineer, do hereby declare the nature of this
invention to be as follows:
-
This invention is a further development of the improvements in hoisting and
lowering gear described in the Specifications of Letters Patent Nos. 24137 of 1893
and 18941 of 1896; and it has for its object to simplify the apparatus and better
adapt it for raising, suspending, disengaging and lowering laundry poles and other
articles such as bicycles which may be conveniently stowed by suspension from a
roof or ceiling.
The improved apparatus under one modification comprises a bracket piece which
may be permanently secured to the joisting or other part of the roof or ceiling by
a screw bolt or other means, the said bracket being formed with vertical pockets
or recesses in which are fitted two rope pulleys whose spindles are carried by the
bracket on horizontal axes. The pulleys may be parallel to each other or set at
an inclination, and over each is passed a rope, wire or chain, the ends being secured
to a crosshead having a hook or eye for suspending the load. A single rope may be
used, doubled at its mid length and provided with a ring or other hand catch for
use in the raising and lowering operations, whilst the single ends are secured to
opposite sides of the crosshead. The crosshead has a central eye extending upwards
between the ropes, and when the load is raised this eye passes up between two
hooks secured on the bracket piece either of which may be used to carry the load.
By pulling either rope in advance of the other the eye on the crosshead is tilted out
of its normal vertical line and is caused to pass over the hook towards which it
is inclined, and on letting go the ropes the hook engages the eye and the load is
thereby suspended. When again lowering the load the ropes are drawn equally
taut so that the eye on the crosshead is lifted off the hook engaging it and is drawn
to its normal vertical position in which it is free to pass downwards between the
hooks. In lieu of forming an eye on the crosshead to engage with hooks on the
supporting bracket, a double hook may be formed on the crosshead to engage with
either of two eyes formed on or carried by the bracket, or other catches or retaining
devices such as those described in the specifications before referred to may be used
for suspending the load.
In dealing with laundry poles or like articles of considerable length a supporting
bracket with its rope pulleys and hooks for engaging the eye on the crosshead
should be provided for each end of the load, and the ropes carried over guide pulleys
to one terminal hand ring. The invention may however be applied to existing
single and double pulley brackets for laundry poles, by forming on or securing to
each pulley bracket an eye or a hook with which a corresponding hook or eye or
other retaining device at each end of the pole may be adapted to engage when the
pole is raised. In this case the ropes may be pulled so as to tilt or cant the pole

when the relative positions is such that engagement takes place automatically.

Improvements in Means for Raising and Suspending.
We, ROBERT BELL, M.D., of Glenae, Aimisfield, near Dumfries, in the County
of Dumfries, and ROBERT MAGUIRE, of 4, Wellfield Street, Springburn, in the
County of the City of Glasgow, Engineer, 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 is a further development of the improvements in hoisting and
lowering gear described in the Specifications of Letters Patent Nos. 24137 of 1893
and 18941 of 1896; and it has for its object to simplify the apparatus and better
adapt it for raising, suspending, disengaging and lowering laundry poles and
other articles such as bicycles which may be conveniently stowed by suspension
from a roof or ceiling.
On the accompanying drawings, Figure 1 is a front elevation and Figure 2 a
plan of one modification of the apparatus sufficient for the purpose of illustrating
our invention. Figure 3 shows a modified form of the retaining hook, and Figure 4
shows a modified form of the crosshead forming part of the hoisting and lowering
gear.
The improved apparatus comprises as shown by Figures 1 and 2 a bracket piece A
which may be permanently secured to the joisting or other part of the roof or ceil-
ing by a screw bolt or bolts or other means, the said bracket A being formed with
vertical pockets or recesses B in which are fitted two rope pulleys C whose
spindles are carried by the bracket on horizontal axes. The pulleys may be parallel
to each other, or set at an inclination as shown and over each is passed a rope,
wire, or chain E, the ends being secured to a crosshead F having a hook or eye for
suspending the load. A single rope E may be used, doubled at its mid length and
provided with a ring or other hand catch for use in the raising and lowering opera-
tions, whilst the single ends are secured to opposite sides of the crosshead F. The
crosshead F has a central eye F extending upwards between the ropes E, and when
the load is raised this eye ¹ passes up between two hooks G secured on the bracket
piece A either of which may be used to carry the load. By pulling either rope E
in advance of the other the eye FI on the crosshead F is tilted out of its normal
vertical line and is caused to pass over the hook towards which it is inclined, and
on letting go the ropes E the hook engages the eye F1 and the load is thereby sus
pended. When again lowering the load the ropes E are drawn equally taut so
that the eye on the crosshead F is lifted off the hook engaging it and is drawn
to its normal vertical position in which it is free to pass downwards between the
hooks G. In lieu of forming an eye on the crosshead to engage with hooks on
the supporting bracket, a double hook may be formed on the crosshead to engage
with either of two eyes formed on or carried by the bracket, or other catches or
retaining devices such as those described in the specifications before referred to
may be used for suspending the load. Or a single hook G may be used and may
be placed at either side of the centre line.

page_text: An alternative form of hook G such as shewn at Figure 3 may be employed and
in conjunction with this a crosshead F of the form shown at Figure 4 is used. In
raising the load the open eye of the crosshead F bears against the lower
limbs G2, G3, of the hook G and is diverted out of its true course, but on clearing
this end of the hook G the open eye F¹ engages the limb G³ and slides down the
upper surface of said limb until it rests on the limb G. On lowering the load the
ropes are first pulled until the open eye F sliding up the under side of the limb G³
clears the limb G2, when the ropes are then released and the load lowered.
In dealing with laundry poles or like articles of considerable length a supporting
bracket such as shown at Figures 1 and 2 with its rope pulleys and hooks of either
of the forms shown for engaging the eye on the crosshead should be provided for
each end of the load, and the ropes carried over guide pulleys to one terminal hand
ring. The invention may however be applied to existing single and double pulley
brackets for laundry poles, by forming on or securing to each pulley bracket an
eye or a hook preferably such as shown at Figure 3 with which a corresponding
hook or eye or other retaining device such as shown at Figure 4 at each end of
the pole may be adapted to engage when the pole is raised. In this case the ropes
may be pulled so as to tilt or cant the pole to cause the engagement of the hooks
and
eyes or to effect their disengagement when the relative positions is such that
engagement takes place automatically.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is:
1. Hoisting and lowering gear constructed and arranged to operate substan-
tially as described with reference to the accompanying drawings.
2. In hoisting and lowering gear the combination with a fixed bracket and pulleys
thereon carrying a rope or ropes, wires or chains, of a crosshead attached to the free
ends of the rope, the said crosshead being formed with an eye or hook adapted to
engage with a hook or eye on the bracket by which the load on the crosshead is
suspended, the engagement and disengagement of the hook and eye being effected
substantially in the manner described.
3. In apparatus for hoisting or lowering laundry poles or like articles, the com-
bination with each fixed rope pulley brackets of an eye or hook thereon and cor-
responding hooks or eyes on the pole or article the latter being put into and out
of engagement with the fixed hooks or eyes by operating the raising and lowering
ropes substantially as described.
