PROVISIONAL SPECIFICATION left by the said Frederick James Harrison
at the Office of the Commissioners of Patents on the 9th September 1882.
FREDERICK JAMES HARRISON of Queen's Road, Rock Ferry in the County of
Chester, "IMPROVEMENTS IN MACHINERY OR APPARATUS FOR RAISING, LOWERING,
AND CONVEYING SUBSTANCES OR MATERIALS
"
The invention has reference to machinery or apparatus for raising, lowering, and
conveying substances, or materials, to different parts.
In one form of apparatus according to this invention, two vertical frames are
built up in sections and provided with endless lifting chains and buckets arranged
to run in between, and are so constructed that they can be extended or shortened
to suit the depth from which the material is to be raised.
The construction of the sides or main frames for carrying the chain pulleys or
drums, is such that additional plates can be introduced or withdrawn, the plates
being suitably formed to bolt or be otherwise securely fixed to each other. The
endless lifting chains pass over suitably formed wheels or drums, and are made up
of loose links with cross bars or bolts, pitched at certain distances and which pass
through the links and couple their ends together. On these bars or bolts buckets,
trays, or arms are fixed which are pitched at such distances that a certain number
of buckets and the intervening portions of chain may be removed so that if also a
certain number of the side plates or sections be removed from the frames, then
when the side frames and the chains are recoupled they will be of suitable
respective lengths for operating to the required depth or distance.
In some cases it will be convenient to employ horizontal travellers for clearing
away the material elevated or for conveying it to the feeding end of the elevator as
for example in drifts in coal mines, in ships' holds, or in other situations for a
variety of purposes.

page_text: In constructing such horizontal travellers according to my invention the side
frames are constructed in sections similarly to the vertical elevator sides and the
travelling portions run over wheels or drums after the manner of the elevator
chains and the distance between the centres of such wheels or drums is capable of
adjustment to suit the distance the materials have to be carried.
The loose links of the elevator chains are permanently jointed in lengths equal
to the pitch of buckets trays or arms, and the joints at their ends by rods or bolts,
onto which the buckets are fixed, as already stated are of a temporary character to
allow of a required number of buckets and chains being readily removed, and of
recoupling as before mentioned. When two vertical elevators are placed side by
side down a ship's batchway into the hold, the chain, barrels, or wheels may be
driven by means of toothed gearing, or if working at some distance apart multiplying
gear fixed on the head and driven by means of a chain or rope, may be used to
communicate motion from one to the other but the elevators may be driven by
other convenient means according to the circumstances of particular applications.
A clutch coupling may be added so that either elevator may be worked
independently from the same gearing; a brake may also be applied and a ratchet
wheel when necessary The travellers may be driven direct from the elevator drum
shafts, or in some cases separately according to circumstances.
The elevator and traveller are provided with guides and with guide or steadying
rollers.
Suitable shoots or feeding troughs are provided for feeding and for removing
material from the machine.
The travelling bands are formed of narrow pieces of iron with one edge slightly
overlapping the other; or may be formed with buckets trays or arms; thereon in
place of flat plates. The construction is such that, as in the case of the elevator
chains, links are capable of being readily withdrawn or added so as to reduce or
increase the operating length. I provide a simple arrangement of mechanism con-
structed with levers, or screws for holding the frame sides in position whilst a plate
is withdrawn or the length of chain is altered, and this appliance is constructed so
as to draw the two ends of chain together and hold them whilst the bolt or rod is
passed through the links.
The sides or main frames are secured on to a suitable platform.
Apparatus according to my invention may be constructed in modified forms
adapted for dealing with various materials and under different conditions without
departing from the essential features of my invention. Also arms, buckets trays &c.,
may be employed whichever may be most suitable for the class of substance to be
dealt with. My improved apparatus may also be made in forms suitable for lifting
and conveying liquids.

FREDERICK JAMES HARRISON, of Queens Road, Rock Ferry, in the County of
Chester "IMPROVEMENTS IN MACHINERY, OR APPARATUS FOR RAISING, LOWERING
AND CONVEYING SUBSTANCES OR MATERIALS
The Invention has reference to machinery, or apparatus for raising, lowering and
conveying substances, or materials to different parts.
In one form of apparatus according to this Invention two vertical frames are
built up in sections and provided with endless lifting chains and buckets arranged
to run in between and are so constructed that they can be extended, or shortened
to suit the depth from which the material is to be raised.
The construction of the sides, or main frames for carrying the chain pulleys, or
drums is such that additional plates can be introduced or withdrawn, the plates
being suitably formed to bolt or be otherwise securely fixed to each other.
The endless lifting chains pass over suitably formed wheels, or drums and are
made up of loose links with cross bars, or bolts, pitched at certain distances and
which pass through the links and couple their ends together.
On these bars, or bolts, buckets, trays, or arms are fixed, which are pitched at
such distances that a certain number of buckets and the intervening portions of
chain may be removed so that, if also a certain number of the side plates or
sections be removed from the frames, then when the side frames and the chains are
recoupled they will be of suitable respective lengths for operating to the required
depth, or distance.
In some cases it will be convenient to employ horizontal travellers for clearing
away the material elevated, or for conveying it to the feeding end of the elevator
as for example in drifts in coal mines in ships holds, or in. other situations for a
variety of purposes.
In constructing such horizontal travellers according to my Invention the said
frames are constructed in sections similarly to the vertical elevator sides and the
travelling portions run over wheels, or drums after the manner of the elevator
chains and the distance between the centres of such wheels or drums is capable of
adjustment to suit the distance the materials have to be carried.
The loose links of the elevator chains are permanently jointed in lengths equal
to the pitch of the buckets, trays, or arms, and the joints, at their ends by rods, or
bolts onto which the buckets are fixed, as already stated are of a temporary
character to allow of a required number of buckets and chains being readily removed
and of recoupling as before mentioned.
When two vertical elevators are placed side by side down a ships hatchway into
the hold, the chain, barrels, or wheels may be driven by means of toothed gearing,
or if working at some distance apart multiplying gear fixed on the head and drum
by means of a chain, or rope may be used to communicate motion from one to the
other but the elevator may be driven by other convenient means according to the
circumstances of particular applications.
A clutch coupling may be added so that either elevator may be worked
independently from the same gearing; a brake may also be applied and a ratchet
wheel when necessary, the travellers may be driven direct from the elevator drum
shafts, or in some cases separately according to circumstances.
The elevator and traveller are provided with guides and and with guide, or
steadying rollers.

my Invention as applied for raising cargo from a ships hold.
Figure 2 is a side elevation of Figure 1.
Figure 3 is a perspective view being a detail of the elevator bucket, or tray.
Figure 4 is an elevation of the carrier according to my Invention.
Figure 5 is an end section of the carrier.
In the form of apparatus according to this Invention illustrated in the Drawings
there is shown a duplex apparatus for raising lowering and conveying substances.
Each apparatus consists of two vertical frames A. A which are built up in sections a
and provided with endless lifting chains B and buckets or trays C and plates C¹
see Figures 1 and 3. The chains B and buckets or trays C are arranged to run
in between the vertical frames A and are so constructed and hung that they can
be extended, or shortened to suit the depth from which the material is to be raised.
I effect this extending and shortening by means of the vertical screwed rods D
which raise, or lower the shafts E which run in bearings F which work in the
vertical slides G in the side guide frames H. These bearings F are extended to
form screwed journals F¹ through which the screwed rods D work. The screwed
rods D are worked by the bevel gears J operated by the shaft J' and winch
handle J2 It will thus be seen that the elevators C and their side frames A can
be raised, or lowered by turning the screwed rods D. The construction of the
vertical frames A is such that the additional plates a can be introduced, or
withdrawn, the plates a being suitably formed to bolt, or be otherwise securely
fixed to each other at a¹
The endless lifting chains B pass over suitable wheels, or drums I mounted on
the shafts E at the top of the apparatus and pulleys K at the bottom of the
apparatus. One, or more intermediate guide pulleys K¹ being provided to carry
the chains. When the length of the side frames is altered by removing one, or

page_text: more of the plates a an amount of links of the bucket chain equal in length to the
length of plates a will have to be removed. The elevator, or bucket chain is made
up of lengths of fixed jointed links. These lengths correspond to the lengths of the
side plates a that is to say the plates a would be half the length of the length of
the fixed jointed link piece, as will be seen. These lengths of fixed jointed links
are jointed together by bolts which may either be simple bolts, or extend and form
a connecting rod between each side of the elevator chains.
Upon reference to the Drawings it will be seen that in Figure 3 the bars Clare
turned up at the ends and fill up, or cover the space between the successive buckets,
or trays and so prevent material from falling away when emptying. The material
such as grain is delivered from the buckets, or trays into a hopper L and shot
onto a carrier N and is led away from such carrier, or carriers to the required
position. The carrier N consists of metal plates n jointed together by links n', the
metal plates n overlapping, thus the plates and connecting links form an endless
metal band. The chains take over drums, or pulleys M provided with axles m
which run in bearings in the frame O of the carrier N.
The elevators are driven by the bevel gear E¹ and bevel gear E² which receives
motion from the pulleys and gear E³.
By the use of the bevel gear E', the elevators will travel in different directions,
so that the material which is delivered from one elevator will be delivered onto a
carrier N on one side, whilst the material which is delivered from the other elevator
will be delivered onto a carrier N on the other side as shown in Figure 1.
Having now described the nature, object and purposes of my Invention and
shown how the same is constructed and works, I would have it understood that
my Invention may be constructed in modified forms adapted for dealing with
various materials and under different conditions, such as on board ship, in mines,
or for warehouse purposes, without departing from the essential features of my
Invention, for example arms buckets, or trays may be employed for the elevation,
or lowering of goods suited to them. What I claim is
First In elevators of the class herein described the raising and lowering of the
elevating mechanism by screws and bevel gear, substantially as herein set forth
and as shown in the Drawings hereto annexed.
Second The construction of elevator arranged with the buckets C and the
plates C¹ as herein described and for the purposes set forth and as shown in the
Drawings hereto annexed.
Third A duplex elevator constructed geared and arranged to work as herein
described for the purposes set forth and as shown in the Drawings hereto annexed.
Fourth The construction and arrangement of endless carrier consisting of the
combined arrangement of plates and endless chains as herein described in reference
to Figures 4 and 5 of the Drawings hereto annexed.
In Witness whereof, I the said Frederick James Harrison have hereunto set my
hand and seal this eighth day of March in the year of our Lord one
thousand eight hundred and eighty three
