PROVISIONAL SPECIFICATION.
Improvements in Rope Grips for Haulage and like Purposes.
JAMES FREDERICK PHILLIPS of Chapel Street Leigh in the County of Lancaster,
Engineer do hereby declare the nature of this invention to be as follows:-
This invention has for its object improvements in the means for readily and firmly
attaching or connecting coal tubs to continuous or intermittent colliery haulage
ropes by means of a device linked to the end of the lashing chain and so arranged
as to hook on to the wire cable or rope and in taking the pull of the tub or tubs
of coal the strain operates on a cam or eccentric surface, or by a bolt or clamp
operating in connection there with and in such manner as to tightly and firmly
embrace the rope without the tendency of the slipping and destruction that occurs.
with the ordinary lashing chains which are wound round the rope and then hooked.
Such method in passing over pulleys is very apt to become loosened and consequently
allows the tubs to run back and collide with the succeeding ones, and my invention
is to overcome these difficulties and the inconvenience occasioned thereby.
Instead of a cam surface (to which one end of the chain is connected) pressing
the rope against the fixed hook or friction surface, it will be obvious that I may
employ a hinged clamp in such manner that say in over-head haulage the chain
would be linked to the one arm of the clamp which bas its hinge above, and the
other side corresponding, the chain from the one arm could be brought around the
other and thus the weight serve to more securely connect the device to the rope.
Another modification of my invention is a screw operating through the clamp bracket
against the rope which although not automatic in its action can be securely attached
by the "hooker on" independent of the automatic lock before referred to and in
a compact form to admit of freely passing over the drums or pulleys. Balls or
rollers can in some cases be advantageously employed in the gripping surfaces.
Several modifications can obviously be arranged but in any case my invention
is applicable either in straight or irregular haulage and capable of being immediately
disconnected at the desired point.

I, JAMES FREDERICK PHILLIPS of Chapel Street, Leigh in the County of Lancaster,
Engineer 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 :-
This invention has for its object improvements in the means for readily and firmly
attaching or connecting coal tubs to continuous or intermittent colliery haulage
ropes by means of a device linked to the end of the lashing chain and so arranged

page_text: as to hook on to the wire cable or rope and in taking the pull of the tub or tubs
of coal the strain operates on or in the normal position causes a cam or eccentric
surface to tightly or firmly embrace the rope without the tendency of the slipping
and destruction that occurs with the ordinary lashing chains which are wound two
or three times round the rope and then back hooked. Such method in passing
over pulleys is very apt to become loosened and consequently allow the tubs to
run back and collide with the succeeding ones and my invention is to overcome
these difficulties and the inconvenience occasioned thereby or from the difficulties
attending the loosening of such fastening in endless and continuous running ropes.
On the accompanying drawings
Figs. 1 and 2 shew front and back views respectively in which it will be seen
that the pendulum cau arm A, is of a suitable length to prevent the twist of the
rope and is connected to the rope clip B at the point C.
In order to better illustrate the application of this system I have shewn at Fig. 3
the attachment to the rope in pulling out the tubs of coal in a "brow" in the
workings to the pit bottom for raising. In some instances where there is a "jig
i.e. to lower the full tubs or in lowering the empties in a brow the attachment before
described is put on the reverse way as shewn at Fig. 4. The direction of travel of
the rope being indicated by the arrow.
Having thus particularly described and ascertained the nature of my inven-
tion and in what manner the same is to be performed I declare that what I
claim is
In rope grips for haulage and like purposes the combination of the pendulum
arm A being provided with a cam or eccentrie surface hinged to the clip B for
automatically gripping the haulage rope whether on levels or gradients such arm
being of a suitable length to prevent the twist of the rope and to freely adapt itself to
passing around curve pullies substantially as described and illustrated on the
accompanying drawings.
