PROVISIONAL SPECIFICATION.
Improved Back Chain for Horses and other Animals.
We WILLIAM HENRY BAILEY of Tranmere Street Hulme Manchester in the
County of Lancaster Mechanic, JOHN HAMILTON BRINDLE of Sewerby Street
Moss Side Manchester Gentleman, ARTHUR TAYLOR NEWBOLD Springs Bury in
the county aforesaid Gentleman and JAMES MASON of Elton Bury aforesaid
Sanitary Engineer do hereby declare the nature of this invention to be as
follows:-
We construct our chain essentially on the same principle as our patent driving
chain No. 15,222 of 1893 but in place of balls we may use a roller horizontally or
barrel shaped or a sleeve with or without an inner sleeve or bush and the links may
be either recessed at their ends and countersunk or left plain. We intend our
chain to be used as a back chain for horses and other animals this chain to be made
in metal preferably all parts steel the rollers or balls have a greater circumference
than the width or depth of the sides of the links and the chain will travel along the
groove in the saddle or over the saddle plate ou its rollers or balls.
It will reduce
friction, give greater ease and comfort to the animal, facilitate carrying power aud
avoid making sores on the animals backs. Back chains can be made wholly of our
invention or part only namely that part which rides on or in the saddle and the ends
may be made of leather or curb open or other link chain with suitable hooks links
swivels &c. for fixing to each other or attaching to the cart shafts or other
vehicle.

We, WILLIAM HENRY BAILEY, of Tranmere Street, Hulme, Manchester, in the
County of Lancaster, Mechanic, JOHN HAMILTON BRINDLE, of Sewerby Street,
Moss Side, Manchester, aforesaid, Gentleman, ARTHUR TAYLOR NEWBOLD,
of Springs, Bury, in the said county, Gentleman, aud JAMES MASON, of Elton,
Bury, aforesaid, Sanitary 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 is designed to provide a back chain for use with the saddles or
back-pads forming part of the harness of draught horses or other animals.
With these chains as at present constructed we find that there is a great amount
of friction owing to the weight of the vehicle and load and that consequently they
do not move to and fro with as much freedom as is desirable to keep the load
adjusted and give freedom to the movement of the animal.
This invention consists essentially in making an anti-friction back chain for
draught animals constructed with longitudinal links and cross pins with two or more
LD077

page_text: balls placed side by side on each cross pin each of greater diameter than the width
of the longitudinal links.
It will be fully described with reference to the accompanying drawings.
Fig. 1. Side elevation of back chain partly in section.
Fig. 2. Front elevation of same partly in section.
Fig. 3. Front elevation partly in section showing a modified form of link.
The side or longitudinal links A are made with rivet holes a and are connected
by transverse pins or rivets B. On each of these transverse pius we place two or
more balls C free to rotate thereon.
The balls C are made of greater diameter than the width of the links so that when
the chain is laid upon a flat surface the balls will rest upon it and allow of the chain
being moved thereon longitudinally without the links A coming in contact with the
surface and with very little friction.
The balls C are perforated with a hole through their transverse axis and are
made of metal preferably of hardened steel and the links A and pins B are also
preferably constructed of steel.
The links A may be made straight as in Fig. 1 or they may be made of the
modified form shown in Fig. 3 cut away so as to fit one into the other and the
pins B may be made with or without a shoulder at the ends as may be found most
desirable or convenient.
In use the chain will lie in the groove of the saddle plate, the balls resting on the
plate. It will reduce friction in movement and will give greater ease and comfort
to the animal, facilitate the carrying power and avoid dragging the saddle and
making sores on the back of the animal.
These back chains may be made wholly of this form or that part only which rests
on the saddle may be so made and the ends may be made of open link chain leather
or rope and with suitable hooks links and swivels for attaching to the shaft of the
cart or other vehicle.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed we declare that what we
claim is :-
A back chain for the saddle or pad of draught animals constructed with
longitudinal links connected together with cross pins and two or more perforated
balls on each pin the balls being of greater diameter than the width of the links
substantially as and for the purposes described.
