IMPROVEMENTS IN HAULAGE CLIPS
Year: 1885

page_text: THOMAS JAMES LINDSAY Colliery Manager Castlehill Iron Works, Carluke,
Lanarkshire, do hereby declare the nature of my invention for IMPROVEMENTS IN
HAULAGE CLIPS to be as follows:-
The clip is intended for attaching Tubs or Wagons to Ropes or Chains, & is
hinged to the drawbar of the tub or wagon & forms a permanent attachment
thereto, but it is easily detached for repair. It is in the form of a hook, the gap of
which is for the reception of & is made to suit any size of rope or chain, it has
also a link inserted in the body of the hook for coupling the tubs or wagons to each
other. The rope or chain is inserted into the gap of the clip by deflection of the
roads or by the use of pulleys. When the strain is put on the clip in the direction
of the load, it causes a slight deflection of the rope or chain in the gap of the clip
and sufficient frictional resistance is thereby obtained to hold the rope or chain
against the weight of the load. The clip can be used on steep gradients, level or
undulating ground & on either straight or curved roads above or underground.

THOMAS JAMES LINDSAY Colliery Manager Castlehill Iron Works Carluke do
hereby declare the nature of my invention for IMPROVEMENTS IN HAULAGE CLIPS
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:-
The Clip A as per full sized Drawing attached to this Specification, is in the
form of a hook, with a gap B suitable for any size of rope or chain, and is made in
crucible cast steel. When the attachment is to be made to a chain the inner
edges of the gap A are bevilled of to suit the chain to be used. It is fitted to the
drawbar at each end of the Tub, or other Vehicle, by a bolt, and forms a permanent
attachment to the drawbar of the Tub, but easily detached for repair-When
desired a hole is left in the body of the Clip for the insertion of a long link for
attaching trains of Tubs together.
The action of the Clip in operation is, When the rope or chain is inserted in the
gap of the Clip, and drawn forward in the direction of the load, sufficient tractional
resistance is obtained to move the load of the attached Tub forward with the rope.
The attaching of the Clip is effected by deflecting the rails, so that the Clip is
thrown clear of the rope, the rails being also depressed until the gap in the Clip is
level with the rope; the rails being at this point brought back to the straight the
rope slips into the gap and the attachment is made, the rails being then raised to
their normal level. The detaching is accomplished by depressing the rails as before,
and deflecting in the opposite direction to that by which the attaching is effected,
thus freeing the rope and consequently detaching the hutch when the rails are
again raised to their proper level.
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 ;-
1st. A permanent attachment to the drawbar.
2nd. Prevention of destructive strains on Tubs caused by the attachment of ropes
or chains to the sides or ends, & also prevention of undue strains to ropes.
3rd. Perfect reliability on the steepest gradient, or in undulating ground, or in
turning curves.
4th. It is self acting in attaching and detaching as by depressing the rails and
slightly deflecting in opposite directions at the attaching and detaching points.
5th. A great saving in ropes and chains.
6th. Cheapness, durability and easy repair.
