PROVISIONAL SPECIFICATION.
Improvements in Hand Hoisting and Lowering Gear.
I, ROBERT MAGUIRE of 16 Lamb 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 which relates to improvements in hand hoisting and lowering
gear adapted to warehouses, stores and similar buildings has principally for its
object to relieve the strain upon the hauling rope or chain whilst it is not in use
although a weight is suspended from it.
The apparatus constituting the invention consists of a bolt or rod to which one
end of the hauling rope or chain is connected, the said bolt or rod having provision
for hanging upon it any desired form of "seize " or jaws to carry the goods to be
raised or lowered. From the bolt or rod the hauling rope or chain passes upwards
over a pulley centred in a bracket which is secured to a beam or rafter at the
highest point of the building at which it is desired the apparatus shall work and from
thence the hauling rope or chain passes downwards and has its other end connected
to a ring or handle. The bracket carrying the pulley is composed of two side
cheeks with an eye at the front sufficiently wide to enable the suspending bolt or
rod to pass through and the said eye is so shaped that when the upper end of the
bolt or rod has passed through it, the bolt or rod can be drawn into a recess and
rested upon the two sides or cheeks so as to relieve the strain upon the hauling rope.
For that purpose there is also connected to the bolt or rod one end of a second
rope or chain which passes over a roller centred within the bracket, its other end
being attached to the ring or handle hereinbefore referred to. By operating this
second rope or chain the bolt or rod is drawn into the recess in the bracket and the
strain upon the hauling rope relieved. The bolt or rod is removed from the recess
and lowered through the eye of the bracket in the act of starting to operate the
hauling rope or chain.
"
Means are provided in conjunction with the handle or ring by which when the
is at a low position and the handle or ring has consequently been elevated
it may be brought back to its lowest or any other desired position.

COMPLETE SPECIFICATION.
Improvements in Hand Hoisting and Lowering Gear.
I, ROBERT MAGUIRE, of 16 Queensbill 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 which relates to improvements in hand hoisting and lowering gear
adapted to warehouses, stores and similar buildings has principally for its object
to relieve the strain upon the hauling rope or chain whilst it is not in use although
a weight is suspended from it.

page_text: The apparatus constituting this invention is illustrated by the accompanying
drawings Figures 1 and 2 being elevations and Figure 3 a plan of the hand hoisting
and lowering gear, and it consists of a bolt or rod A to which one end of the
hauling rope or chain B is connected, the said bolt or rod A having provision for
hanging upon it any desired form of "seize " or jaws to carry the goods to be
raised or lowered. From the bolt or rod A the hauling rope or chain B passes
upwards over a pulley D centred at d in a bracket E fixed to or integral with a sole
plate E which is secured to a beam or rafter F at the highest point of the building
at which it is desired the apparatus shall work, and thence the hauling rope or
chain B passes downwards and has its other end connected to a ring, handle or
ball G. The bracket E carrying the pulley D is composed of two side cheeks e
with an eye
at the front sufficiently wide to enable the suspending bolt or rod to
pass through and the said eye is so shaped that when the upper end of the bolt or
rod A has passed through it, the bolt or rod can be drawn into a narrowed recess e
and rested upon or locked by the two sides or cheeks e so as to relieve the strain
upon the hauling rope B. For that purpose there is provided a ring which
embraces the hauling rope B and has one end of a second rope or chain H attached
to it, which passes over a roller or pulley ¹ centred on the sole plate E', the other
end of the rope hanging free and having a ring, handle or ball attached to it. By
operating this second rope or chain H the bolt or red A is drawn into the recess e²
in the bracket E, as indicated by the dotted lines at Figure 1, and the strain upon
the hauling rope B is relieved. The bolt or rod A is removed from the recess e
and lowered through the eye e' of the bracket E in the act of starting to operate
the hauling rope or chain.
As an alternative to the above method and as shown by Figure 2 the pulley D
may be centred at d in the bracket E in order that the locking of the bolt A may
be effected automatically and the rope H used ouly for relieving the bolt from its
locked position when it is desired to lower the goods. In this case the bolt A on
being drawn up acts against the inclined edge e' of the side cheeks e and is thus
brought into position to pass through the eye e¹. When the bolt A has been raised
through the eye e¹ the hauling rope B is slackened slightly to permit the bolt to act
on the inclined edge of the side cheeks e and bring it into resting or locking
position.
Means consisting of a third rope I having hooks at either end one for embracing
the hauling rope B and the other for embracing the bolt A are provided by which
when the "seize" is at a low position and the handle, ring or ball has consequently
been elevated and abuts against a stop e formed on the side cheeks e it may be
brought back to its lowest position, or as indicated at Figure 2 this third rope may
have one of its ends hooked on to the hauling rope over the ball G the other
hooked eud embracing the neck of the bolt A thus leaving the goods in any
desired position.
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
claim is :-
The improved hand hoisting and lowering gear constructed and arranged
substantially as described with reference to the annexed drawings.
