PROVISIONAL SPECIFICATION.
A Spiral Shoot to Facilitate and Improve the Removal of Material
from. a. Higher to a Lower Level..
I, LEWIS HENDERSON BALLANTINE of Borrowstounness in the County of
Linlithgow, Scotland, do hereby declare the nature of this invention to be as
follows:-
The Shoot or Conductor may be of any dimensions required, is built in a spiral
form of any material, with spiral openings between the turns of suitable size-lt is
attached to vertical bars running from one end to the other of the inner side of the
Shoot or to an inner circular cylinder running' from top to bottom of the shoot-
When vertical bars are used they are continued and shaped at top into a swivel hook
or eye for reception of a swivel hook of a hoisting chain-On the outer-side of the
spiral Shoot or Conductor is attached or fixed a guide made of a strip of iron, the
edges of which are inverted so as to grip the corresponding attachment after
mentioned, and is fastened round the outside spiral frame of the Shoot or Conductor,-
which guide when the Shoot or Conductor is lowered or raised fits into and works
upon two or more outvert hooks placed in proper position upon any fixed or moveable
substance from which the Shoot is desired to operate-the swivel hook on the hoisting
or suspending chain allowing the Shoot or Conductor to revolve as the guide permits
in the lowering or raising. The guide may be also formed as a box-guide with slot
or opening on face, fastened round the outside spiral frame of the Shoot or Conductor
and fitted into or working upon a revolving castor or castors fixed in proper position
on any fixed or moveable substance as aforesaid and working in the slot.
The coil of the Shoot or Conductor may be round, oval, or square.
In loading from a Scoop such as is used at Coal Hoists an attachment shaped so as
to meet and work into the upper end or any desired part of the spiral Shoot or
Conductor will be fixed upon the lower edge of the scoop.

page_text: The Shoot or Conductor may be worked by the use of steam or hydraulic power
or by back balance, hand or horse power when used in suspension and may also be
used as a stationary or fixed shoot-It may be used in loading and removing all
substances, for the purpose of preventing damage by concussion in falling, and other
purposes.

A Spiral Shoot to Facilitate and Improve the Removal of Material
from a Higher to a Lower Level.
I LEWIS HENDERSON BALLANTINE of Borrowstounness in the County of
Linlithgow, Scotland 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 :-
The Shoot or Conductor may be of any dimensions required-It is built in a spiral
form of any material, with spiral openings between the turns of suitable size-It is
attached to vertical bars running from one end to the other of the
inner side of the shoot, or to an inner circular cylinder running from
top to bottom of the shoot. When vertical bars are used they are continued
and shaped at the top into a swivel hook or eye for the reception of a
swivel hook of a hoisting chain-On the outer side of the spiral shoot or conductor
is attached or fixed, a guide made of a strip of iron the edges of which are inverted
so as to grip the corresponding attachment after mentioned, and is fastened round the
outside spiral frame of the Shoot or Conductor, which guide, when' the Shoot or
Conductor is lowered or raised, fits into and works upon two or more outvert hooks
placed in proper position upon any fixed or moveable substance from which the Shoot
is desired to operate, the swivel hook on the hoisting or suspending chain, allowing
the Shoot or Conductor to revolve, as the guide permits in the lowering or raising
The guide may be also formed as a box guide with slot or opening on face fastened
round the outside of spiral frame of the Shoot or Conductor, and fitted into or working
upon a revolving castor or castors fixed in proper position upon any fixed or moveable
substance as aforesaid, and working in the slot.
The coil of the Shoot or Conductor may be round, oval or square.
In loading from a Scoop such as is used at Coal Hoists, an attachment shaped so as to
meet and work into the upper end or any desired part of the Spiral Shoot or Conductor
will be fixed upon the lower edge of the scoop.

page_text: The Shoot or Conductor may be worked by the use of steam or hydraulic power or
by back balance, hand or horse power, when used in suspension, and may also be used
as a stationary or fixed shoot-It may be used in loading and removing all
substances for the purpose of preventing damage by concussion in falling and other
purposes.
The drawings hereto annexed shew the form and nature of my said Invention.
The letter" a "shews the vertical bar or cylinder running from end to end of the
Shoot."6" is the Conductor-"c" is the guide and "d" is the attachment between
shoot and scoop.
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 :-
1. The construction, arrangement of parts and application of the spiral Shoot and
attachments before described, to the lowering of material from a higher to a lower
level.
