IMPROVEMENT IN HOISTS FOR THE RAISING OF MATERIALS, MORE ESPECIALLY FOR BUILDINGS IN COURSE OF ERECTION
Year: 1884

page_text: I JAMES TOTTENHAM, of 9 Horton Terrace, Acacia Road, Wood Green in the
County of Middlesex Builders Foreman do hereby declare the nature of my
Invention for IMPROVEMENT IN HOISTS FOR THE RAISING OF MATERIALS, MORE
ESPECIALLY FOR BUILDINGS IN COURSE OF ERECTION to be as follows
-
The difficulties experienced in raising materials for use in buildings in course of
erection are considerable and the usual means employed by the labourer, with the
hod, the fall, or the single drum, not only entail a great deal of labour, but often
cause considerable delay in the execution of works from the slowness with which
materials are raised These difficulties are more especially felt when the buildings
exceed 30 to 40 feet in height.
My invention not only does away with a large amount of labour but facilitates
the work and enables less than a third of the men necessary under the old systems
to more expeditiously carry out a greater amount of building
The hoist which can be used on any ordinary scaffold consists of two drums, one
at the top and the other at the bottom of the scaffold Around these drums is
placed a continuous band of good woven material, on which at intervals of about
bfteen (15) feet are placed joints for affixing baskets, pails or hooks which may be
attached to any articles required to be raised
The joint which is made of metal, consists of two plates hinged in the centre to
educe the friction caused by passing round the drum The plates are connected
by four (4) metal bars the end ones being used to fasten the joint to the band,
& the inner ones for attaching a double hook which will receive upward or down
ward hangings
Under the inner bar at the lower part of the joint cushions of india rubber are
placed to prevent the jarring and probable breakage of the joint by heavy weights
being attached suddenly while the hoist is being worked
The hoist is worked at the top of the scaffold by a double purchase gear and
with moderate weights one man can keep it working at a height of 60 ft enabling
twelve (12) labourers to keep 30 bricklayers well supplied with material
The hoist would not only be useful for raising materials for buildings but can
easily be used in warehouses offices & shops where means are needed for rapidly
carrying parcels, books, and boxes from floor to floor
My invention is moderate in cost, & being simple in construction is very unlikely
to get out of order

page_text: I JAMES TOTTENHAM of 9 Horton Terrace, Acacia Road Wood Green in the
county of Middlesex Buildors Foreman do hereby declare the nature of my said
invention for 'IMPROVEчFNT IN HOISTS FOR THE RAISING OF MATERIALS MORE
ESPECIALLY FOR BUILDINGS IN COURSE OF ERECTION,' and in what manner the
samo is to be performed to be particularly described and ascertained in and by the
following statement
The object of this invention is to so construct or arrange hoists for raising
natural of any kind to various heights of a warehouse, factory or other structure
but is more especially intended for raising stone, bricks, or other material used for
the erection or the repairs of buildings.
The invention may be fitted within a framework of scaffolding or on the floor of
a building according to the purpose for which it is to be used
My invention will be understood by the annexed drawings Figures 1, 2 and 3
and conists of an endless band or belt A composed of woven fabric or webbing in
sections each section being connected by screw bolts Band plates C to a cross pin 1)
to the ends of which are two plates or links E provided at a part of their length
with rectangular slots within which I fit cushions of India rubber or other yielding
material upon which the squared ends of a cross bar can lodge themselves said
cross bar forining the connection for a curl or loop H of a plate which forms the
book I on or into which baskets bags, buckets bundles or any compact articles
can be hung either by its handle or by an attachable hook or by cord or rope
according to requirement such as I bave represented at Figure 2 where the invention
as more particularly represented for raising material used for building purposes
such as buckets for lifting mortar baskets barrows or other articles in which
bricks or material may be placed In Figure 2 I show a full bucket being raised
in the direction of the arrow being suspended from the hook I by means of a
detachable hook link, or bai J by its bale, the band A. being worked by the drum K
from the power gear L which may be provided with a fly wheel and crank handle
or by two fly wheels M as at Figure 3 for turning the same the bite of the band
upon the drum which I prefer should be ribbed being sufficient to prevent slip
whatever the weight of the load may be, the lift being always in a direct vertical
hne and steady without twist or swinging action thus the material is raised without
concussion or violent shaking The plate before referred to has a similar hook N
in the reverse direction to that marked I by which the empty baskets, buckets or
other receptacles can be hooked and lowered as shown on the left hand side of
Figure 2 when the hook has turned over the drum K.
The charged receptacles as they arrive at the platform P are detached by an
attendant stationed there for the purpose and as the hooks pass over the drum K
empty receptacles such as the basket shown, can be hooked on to the hook N by
an attendant on the opposite side of the frame Q he being also upon the platform P
This second attendant would only be necessary where the loaded buckets or baskets
follow in rapid succession this being more or less determined by the lengths of the

page_text: sections but if the sections are of comparatively great lengths or the working of the
drum slow, the same attendant could not only detach the full receptacles but return
the empty ones
The empty receptacles as they arrive at the bottom of the apparatus or other
desired part between the two drums the lower of which R may be below the
bottom flooring or sunk in a pit I fit a sloping or inclined table S on which the
receptacles rest the hook N continuing its motion releases itself from the receptacles
which then slides down the incline and frees itself from the apparatus
Instead of the sloping table S an attendant may remove the empty receptacles as
they arrive
The hook N has a curl T similar to the curl H but in the reverse direction and
this curl T forms the connection by a transverse bar U to two links or plates V
which are connected to the plates E and form a joint there with and also with the
adjoining section of the web A the end of which is connected to a cross pin D¹ in
the manner explained with reference to D The transverse pin U is slotted at one
end and has a key W which when removed enables the pin Ü to be withdrawn and
the double hook removed when desired
When an extra length of webbing has to be put in or a length removed to shorten
the band A to suit the distance between the two drums K, R, the two screw bolts B
and the plates C are removed and the attachment made
I have heretofore described my invention as applicable to hoisting goods or
materials in buildings but it is equally applicable for raising earth or other material
from excavations such as in the formation of docks and instead of the apparatus
being used for hoisting only it can be employed for lowering goods or for both
raising and lowering
Where material of a loose nature such as bricks, sand or the like, (or it may be
some article such as a window sill or a stone step or timber these being slung on
the hooks) is being raised I purpose arranging a fall down flap above the head of
the attendant who hooks on the receptacles so that as the material passes through
the opening the flap is lifted and then falls by its own weight, thus the attendant
is protected from injury
The invention as shown by the drawing represents the hook I as being the
raising hook on the right hand side of the apparatus but this may serve for
lowering and the hook N for ruising
To prevent the band slewing off the drum sideways I fit 1ollers X as guides
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is
The double hook and its appurtenances shown at Figure 1 as an appliance
forming a joint for an endless band in sections for hoisting material as set forth
and substantially as shown at Figures 2 and 3
