PROVISIONAL SPE
CATION.
A Hoist for Elevating Materials.
We, JAMES HARPER, 132 Easter Road, Plasterer, and JOHN HARPER, 2 Rodney
Street, Blacksmith, both of Edinburgh, in the County of Mid-Lothian, N.B., do
hereby declare the nature of this invention to be as follows:-
This invention relates to a hoist particularly applicable for elevating plaster, bricks
and such like in buildings. The hoist consists of a cast iron or other drum, say
30 inches long by 20 inches in diameter. The ends of the drum are provided with
heavy flanges which act as fly-wheels. The said drum stands on two triangular
frames with journals for the spindle of the drum to revolve in. The said frame is
preferably strengthened by means of stays towards its top and bottom. The sole-
plate of the frame is capable of being screwed down or otherwise attached to the
joisting of the building.
The action of the hoist is as follows:-
Supposing it is desired to elevate a quantity of plaster to the top storey of a
building, the frame carrying the drum is fastened down to the joisting of the room
or place in the building where the plaster is required. A length of rope is then
wound around the drum and the two ends of the rope passed over two pulleys
fastened outside the window or other opening to the outside of the building. The
plaster receptacle is attached to each end of the rope. By means of a cranked handle
on the drum the material is quickly elevated by the winding in of the one portion
of the rope, the other portion of rope simultaneously unwinding itself and lowering
the other receptacle. By means of the large diameter of the drum the hoist works
very rapidly and thus the work of lowering and raising the cement receptacle is
performed with ease and expedition, thus doing away to a large extent with the usual
manual labour. Instead of the double acting arrangement of the hoist we may
employ a single acting arrangement, that is to say we may use the hoist for elevating
and lowering one receptacle only.
The hoist being portable, it can readily be clamped down to any part of the
building for the purpose of elevating and lowering the cement, or whatever is required
at any part of the buildings.

We, JAMES HARPER, 132 Easter Road, Plasterer, and JOHN HARPER, 2 Rodney
Street, Blacksmith, both of Edinburgh in the County of Mid-Lothian, N.B. 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 hoist particularly applicable for elevating plaster, bricks,
and anah like in buildings

page_text: But in order that our said invention may be readily understood and easily carried
into effect we will proceed to describe the same with reference to the accompanying.
drawings in which
Figure 1 is an elevation and
Figure 2 an end view of our hoist and
Figure 3 a section of a building showing the hoist in operation.
As shewn in Figures 1 and 2 of the said drawings, the hoist consists of a wooden
drum A say 30 inches long by 20 inches in diameter. The said drum A is
preferably composed of a number of spars a secured to the flanges a¹ in any con-
venient manner, the spars being arranged at intervals around the periphery of the
flanges so that a space is left between each.
A frame consisting of two triangular or other suitably shaped standards B having
journals b, is provided, within which the spindles C secured to the flanges of the
drum revolve. The said standards are held together by means of stay rods D having
shoulders d formed thereon, the ends of the rods which pass through the standards
being provided with nuts, so that they can be readily braced together or separated in
order to facilitate their removal from place to place and also to enable them to be
more easily passed for example through the window of the building.
A plate di is placed upon the outside of the standards to prevent the wearing away
of the wood by the nuts.
The sole plate of the frame may be secured to the joisting of the building by means
of buckles or stays E having screwed ends e. The said buckles or stays are adapted
to fit round the joist and are caused to hold the standards firmly thereto by passing
the screwed ends through a plate F laid loosely upon the sole plate and securing them
together by nuts.
Or the sole plate may be screwed down or otherwise attached to the joisting of the
building.
Or I may employ an iron or other drum having heavy flanges formed thereon
which act as fly wheels and consequently lessen the amount of labour required to
operate it.
The action of the hoist is as follows:-
Supposing it is desired to elevate a quantity of plaster to the top storey of a
building, as shewn in Figure 3, the frame carrying the drum is fastened down to the
joisting of the room or place in the building where the plaster is required. A length
of rope is then wound around the drum and the two ends of the rope passed over two
pulleys E fastened outside the window or other opening to the outside of the building.
A plaster receptacle F is attached to each end of the rope. By means of cranked
handles G on the drum the material is quickly elevated by the winding in of the one
portion of the rope, the other portion of rope simultaneously unwinding itself and
lowering the other receptacle. By means of the large diameter of the drum the
hoist works very rapidly and thus the work of lowering and raising the cement
receptacle is performed with ease and expedition, thus doing away to a large extent
with the usual manual labour.
When the hoist is situated at the top of the building as shewn, the rope is merely
given two or three turns round the drum in order that it may grip which it readily
does owing to the sparred formation of the drum. But when the hoist is being used
at say the storey marked H (Figure 3) the rope is given a greater number of turns
round the drum before commencing so that there will be no slack rope to wind up
between the lowering of the upper bucket and the raising of the lower which
would be the case if the rope were only turned round the same number of turns as
for a higher storey.
The weight of the empty bucket when descending also assists in raising the full
bucket.
Instead of the double acting arrangement of the hoist we may employ a single
acting arrangement, that is to say we may use the hoist for elevating and lowering
one receptacle only.
The hoist being portable, it can readily be clamped down to any part of the building

page_text: for the purpose of elevating and lowering the cement, or whatever is required at any
part of the buildings.
Having now particularly described and ascertained the nature of our inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
The hoist for elevating materials, substantially as hereinbefore described and shewn
in the accompanying drawings.
