Description of Rope or Chain Haulage.
I, JAMES BLACKBURN Engineer and Colliery Manager Allerton Main Colliery
Woodlesford nr. Leeds do hereby declare the nature of this invention to be as follows:-
An improvement in Friction Gear, it is an apparatus for putting in and out of gear
a shaft on which is fixed a loose pulley, by means of a metal cup termed a true taper,
on the inside and attatched to the loose pulley attatched to a sliding collar with a key
slot cut in, is a cone slightly larger than the cup, this cone is pressed into or withdrawn
from the cup by means of an iron bar in the centre of which the loose collar revolves,
the iron bar at one end is made fast by a bolt or pin to a cross bar or post, the other
end is fitted with a threaded hole or nut through which is passed a screw and this
screw is attatched to a post or cross bar at one or both ends as may be thought
desirable so that by turning a wheel or handle on the screw the cone is pressed into
the taper cup.
An Improvement in Friction Clutch Gearing Applicable for any
Description of Rope or Chain Haulage.
JAMES BLACKBURN Engineer & Colliery Manager Allerton Main Collieries Woodles-
ford nr. Leeds Yorks do hereby declare the nature of my invention for AN IMPROVE-
MENT IN FRICTION CLUTCH GEAR and in what manner the same is to be performed, to
be particularly described and ascertained in and by the following statement :-
The Friction Clutch Gear consists of a She Cone 2 which can be bolted on any
description of Drum, Cog Gear or Clip Pulley. On the same Shaft is a He Cone 1
the centre of which is formed into a sliding collar 6 on the shaft with a key way cut
Dice 21

page_text: in it the collar 6 or Boss projector on the off side or outer side with a grove turned
round it. The cones are moved in and out of gear by means of a Wrought Iron Arm
or lever 3 the one end of which is fixed to a stay 7 parallel with the plane of the cone,
the centre of the lever arm 8 spans round the Grove cut in the projecting collar 6 the
opposite end has a nut 5 formed in it and extends to a screw 4 which is fixed at one
or both ends and revolves in the nut made in the arm this Screw is moved by a
handle 9 fixed in its extreme end and moves the arm backwards and forwards forcing
the Cones in and out of each other and thus putting them in and out of gear. If the
Gear is required to turn a Shaft a key is sunk in the Shaft to fit the key way in the
Collar of the Cone which travels on the fast key thus fixed on the Shaft Or both
the cones can run loose on a fixed Shaft and the power he transmitted direct from Cone
to Cone and thence to any Gear that may be attached to them.
This Gear is especially adapted for Haulage in Mines or up inclines and may be
applied either to Main and Tail or the Endless system of Haulage, for the last named
it is of the utmost importance to have such an application as it enables any number of
roads to be worked at the same time or separately without injuring or interfering with
each other and it further enables haulage to right angles to be worked successfully as
feeders to a Main Road, as it may be applied any juncture without inconveniencing
the haulage or Engine and can be worked by a boy to put to put the Friction in and
out of Gear.
It is also of great service in preventing the wear and tear of ropes as there is no
fendency to break or strain the rope by any sudden jerk which may arise from any
accident on the road. It is further a saving of labour as one man by means of this
Gear can work five or six ropes in one pit. It is not necessary to stop one road to
detach or attach another road. It will work either Vertically or Horizontally as
required and all the roads can he worked from one Shaft. The space it takes up is
very limited each one can be constructed in the space of one foot three inches.
Having now particularly described and ascertained the nature of my said Invention
and in what manner the same is performed I declare that what I claim is
1st. A He & She Cone working into each other Fig. 1. 2.
2nd. An Iron Arm or Lever Fig. 3 connected with a left and right hand Screw
Fig. 4 working in a nut (Fig. 5) attached to the arm.
3rd. An extended Boss or Collar revolving in the arm or Lever (Fig. 6).
4th. The Cone Travelling or working on a fast key on the shaft.
