Improvements in Brake Mechanism of Looms.
RICHARD WHALLEY 71 Higher Eanam Blackburn Hairdresser, and WILLIAM
WELLS,
Chemist and Druggist 97 Bastwell Terrace Whalley Now Road Blackburn,
both in the County of Lancaster do hereby declare the nature of this invention to be
as follows:-
To an improved construction of Brake Wheel and Brake Block in Looms.
We cut or form a groove in the Brake's Wheel rim in the form of V. We make
a Block of hard material that will fit in this groove; leaving a small space between the
bottom of the Block and the bottom of the groove, thus forming a Vacum. This
Block we fix on the shoe of the Brakes Leaver. When the Brake is applied this
Block fits in the groove of the Brakes Wheel binding so tightly that the Loom is
stopped almost instantly.
Dated this Third day of Marchi 1887

We RICHARD WHALLEY of 71 Higher Eanam Blackburn in the County of
Lancaster, Hairdresser and WILLIAM WELLS of 97 Bastwell Terrace Whalley New
Road Blackburn in the County aforesaid Chemist and Druggist 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 relates to an improved construction of brake wheel and brake
block.
According to this invention we cut or form a groove in the rim of the brake wheel
of V form, we make a block of hard material that will fit in this groove leaving a
small space between the brake part of the block and the bottom of the V groove, thus
forming a space. This block we fix on the shoe of the brake lever. When the brake
is applied this block fits in the groove of the brakes wheel binding so tightly that
the loom is stopped almost instantly.
Such being the nature and object of this our said invention the following is a
complete description of same, reference being had to the accompanying drawings:
Fig. 1. is an end elevation of brake wheel and brake.
Fig. 2. is a side elevation of same.
Figs. 3. and 4 shew other means of securing the block to the brake lever.
~
According to this our invention we cut or form in the rim of the brake wheel 1
a V shaped groove 2 in which the brake shoe or block 3 is received. The block or
brake shoe 3 we form of iron or other metal, the portion which comes in contact
with the V groove 2 being covered with leather, rubber or other like material 4
secured in position by rivets 5. 5. This block or brake shoe 3 has on its under side
a projecting lug or lugs 6 which are received in a slot 7 in the brake lever 8. In
existing looms where the brake lever 8 is not adapted for a slot 7 being formed in it,
we employ one or other of the designs shewn at Figs. 3 & 4. In fig. 3 the brake
shoe or block 3 and carrier 9 in which the lugs 6. 6. are received is secured by bolt 10
and nut to the brake lever 8, and in fig. 4 the contrivance is somewhat similar but
the block 3 can be adjusted to the brake wheel 1 by moving the bolt 10 in the slot 11
and by moving the carrier 9 when adjusted being secured by set screws 13.
It will be seen (fig. 1) that the shoe 3 does not press against the bottom of the
V groove 2 but leaves a small space, thus allowing for wear of the shoe 3 and
prevents the same getting “glad.",

page_text: Having now particularly described and ascertained the nature of our said Inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is :-
The improvements in brake wheel and blocks wherein is combined the V grooved
brake wheel, the block 3 and covering 4 as described and as illustrated by annexed
drawings.
