Improvements in or applicable to Hauling Blocks and other like
Devices where a Rope is used and has to be Made Fast or
Belayed.
I, THOMAS RYLAND of Northgate Chester in the County of Chester Engineer
do hereby declare the nature of this invention to be as follows:-
In the use of block tackle by painters in painting the sides of ships, houses, and
the like, also in the use of such tackle for raising heavy articles into lathes, and the
like and for other purposes where the lower block is always within reach, it is very
desirable to have some method of holding fast the rope without having to look
about and find some point to tie it to.
Now this invention is designed to supply this want, and to supply an attachment
of small cost, not in the way, yet always ready when wanted.
It consists in attaching to the side of the lower block near the upper part, a
circular grooved stationary wheel, cam, or projection, and placing a similar rigid
wheel or cam on a link attached to the lower part of the block, having a short
radial motion, so that it can stand either almost touching the other block, or the
two blocks be sufficiently wide apart for the rope to be very easily entered between
them.
The mode of action is as follows:-
:-
Having used the blocks, and the ropes being in tension, the hauling rope is held
by the hand a little above the bottom block. The rope is now passed by the other
hand round the circular grooved drum, wheel, or cam attached to the lever, and
between that and the other drum, cam or wheel, and round the latter lying in the
grooves of these two blocks. The end of the rope now being momentarily held
while the other part is let go, the tension on the block causes the moveable block
to jam the rope against the other block, and the harder the pull the tighter the

required is to again pull upon the rope above the block, when it can be at once
released.
It will be obvious from this description that in place of a grooved wheel rigidly
attached to the free end of a link, an excentric wheel or cam on a fixed pivot
would act nearly as well and the invention does not merely consist of the exact
details already described, but also in the method of fixing the rope by attaching a
moveable gripping device to the lower block so arranged that the grip shall be in
proportion to the pull of the rope, and caused by such pull.

Improvements in or applicable to Hauling Blocks and other like
Devices where a Rope is used and has to be Made Fast or
Belayed.
I, THOMAS RYLAND of Northgate, Chester, in the County of Chester,
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:-
In the use of block tackle by painters in painting the sides of ships, houses and
the like, also in the use of such tackle for raising heavy articles into lathes and the
like and for other purposes where the lower block is always within reach, it is very
desirable to have some method of holding fast the rope without having to look
about and find some point to tie it to.
Now this invention is designed to supply this want, and to supply an attachment
of small cost, not in the way, yet always ready when wanted.
The invention will be understood from the following description, reference being
had to the accompanying drawings, in which,
Figure 1 is a general view of my improved tackle in actual use;
Figure 2, a side elevation ;
Figure 3 a front elevation of the lower block with my attachment applied
thereto; and
Figure 4 a side elevation.
My invention consists, as shown in these figures, of attaching to the side of the
lower block A near the upper part, a circular grooved stationary wheel or
projection B and placing a similar rigid wheel C on a link D attached to the
lower part of the block A having a short radial motion, so that it can stand
either almost touching the other wheel B, or the two wheels B and C be sufficiently
wide apart for the rope to be very easily entered between them. The pin d on
the link in conjunction with the slot in the block limits the movement of the
link.
The mode of action is as follows:--
Having used the blocks, and the ropes being in tension, the hauling rope E is
held by the hand a little above the bottom block. The rope is now passed by the
other hand round the circular grooved wheel C attached to the lever D, and
between that and the other wheel B, and round the latter lying in the grooves of
these two wheels. The end of the rope E now being momentarily held while the
other part
let go, the tension on the block caused by the weight hanging from
the hook F causes the movable wheel C to jam the rope against the other wheel B,
and the harder the pull, the tighter the squeeze, consequently the rope is heid.
To relieve the tension all that is required is to again pull upon the rope E above
the lower block when it can be at once released.
It will be obvious from this description that in place of a grooved wheel rigidly
attached to the free end of a link, an eccentric wheel or cam on a fixed pivot
would act nearly as well, and the invention does not merely consist of the exact
details already described, but also in the method of fixing the rope by attaching a
movable gripping device to the lower block, so arranged that the grip shall be in
proportion to the pull of the rope, and caused by such pull.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. In hauling blocks and other like devices where a rope is used and has to be

page_text: made fast or belayed, the method of fixing the rope by attaching a movable
gripping device to the lower block, so arranged that the grip shall be in
proportion to the pull of the rope, and be caused by such pull substantially as
described.
2. The improvement in hauling blocks or other like devices where a rope has to
be made fast or belayed, which consists in attaching to the lower block near the
upper part a circular grooved stationary wheel or projection and placing a similar
rigid wheel or projection on a link pivoted to the lower part of the block having a
short radial motion, so that it can stand either almost touching the other wheel or
projection or the two wheels be sufficiently wide apart for the rope to be very easily
entered between them, whereby if the hauling rope be laid between the two wheels
and the rope momentarily let go, the tension on the block causes the wheel on
the movable link to jam the rope against the other wheel and hold the rope fast,
substantially as set forth.
3. The combined arrangement and construction of parts forming my attachment
for hauling blocks or the like, substantially as and for the purpose described.
