I JAMES COCKAINE SHAW of 1 Waterloo Road in the County of Dublin
Ireland, Flour Merchant do hereby declare the nature of this invention to be as
follows:-
This Invention has reference to an Improvement in harness used in "Tandem," and
four-in-hand driving.
In harness as at present used in tandem, and four-in-hand driving the ordinary
hames and traces are used in connection with both the wheeler, or shaft animal, and
the leader, the only difference being that the traces of the latter are longer, so as to
enable their free ends to be hooked to the traces of the wheeler.
This method of connecting the two sets of traces works inconveniently and awkwardly,
in practice, in as much as the draught of both animals (wheeler and leader) being
rarely regular the result is that the collar of the wheeler is constantly disturbed, or
displaced, or in other words a kind of to and fro motion is imparted to the collar
owing to the difference in the rate of speed of the two animals.
My Invention is designed to remedy this defect and to this end 1 propose to use
hames, and traces of special construction; that is to say I provide in the first place in
lieu of the usual tug in the hames of the wheeler, or shaft animal, a projecting 'tree'
tug, and secondly I provide a continuous trace for both leader and wheeler which is
attached to the hames of the former in the usual way and is provided with a longitudinal
slot of. suitable length in the vicinity of the collar of the wheeler, so as to be easily,
and conveniently passed over the tree tug above described.
.
By this arrangement it will be obvious that the trace is capable of longitudinal
movement to a certain extent without disturbing, or displacing the collar of the
wheeler and the variation in the motion of the animals is thus provided for, without the
inconvenience above pointed out.
It will be further obvious that separate traces may be used instead of the
continuous one described, in which case the slot is formed in the wheeler trace and
the leader trace is attached to the hames of the former by hook and eye, or other
suitable device.
Dated this 28th day of June 1887.

An Improvement in Tandem" or Four-in-Hand" Harness.
I, JAMES COCKAINE SHAW of 1 Waterloo Road in the County of Dublin, Ireland,
Flour Merchant 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 harness at present used in tandem' and 'four-in-hand' driving, the ordinary
hames and traces are used in connection with both the wheeler, or shaft animal, and
the leader; the only difference being that the traces of the leader are longer so as to
enable their free ends to be hooked to the traces of the wheeler.
This method of connecting the two sets of traces works inconveniently and
awkwardly in practice, in as much as the draught of both animals (wheeler. and
leader) being raroly regular the result is that the collar of the wheeler or shaft
animal is constantly disturbed, or displaced, or in other words a kind of to, and fro,
motion is imparted to the collar owing to the variation in the rate of speed of the
animals.
My Invention is designed to remedy this defect and to this end I propose to uso
haines and traces of special construction, that is to say I provide in the first place in
lieu of the usual tug in the hames of the wheeler, or shaft animal, a projecting tug,
with a button, or cross piece at its free end and secondly I provide a continuous trace
for both leader and wheeler, one end of which is attached to the hames of the leader
in the usual way, and is provided with a longitudinal slot of suitable length in the
vicinity of the collar of the wheeler, so as to be easily and conveniently passed over
the tug above described.
By another arrangement, instead of using a tree tug, and slotted trace as described,
I may use a swivel tug provided with a rectangular slot on the hames of the wheeler
through which the continuous trace is passed, a suitable piu or stop being provided
for the wheeler to pull by.
It is obvious that instead of using a continuous trace for leader and wheeler,
separate traces may be used in which case the wheeler trace is provided with the pin
or stop, and also a suitable device for attachınent of the leader trace.
In order that my said Invention may be more readily understood I attach hereto a
drawing illustrating the method which I prefer to carry out in practice
:- -A, indicates
the wheeler, or shaft animal's collar; B, the swivel rectangular slotted tug, through
which the trace runs ; C, stop or pin on trace of wheeler to pull by; D, trace of
leader connected to trace of wheeler by swivel hook, or other suitable device ;
E, chain for attaching trace to vehicle, and whereby length of trace may be
adjusted.
From this description it will be obvious that the trace of the wheeler is capable of
longitudinal movement through the rectangular slot B, without disturbing, or
displacing the collar A, and the variation in the motion or speed of the leader
and wheeler is thus provided for, without the inconvenience above pointed out.

page_text: The principle herein described may also be applied with advantage to double harness
in the following way.
By providing additional slots at both sides of the hames and instead of securing
the poll chain or strap in the usual way, its free ends are passed through the said
additional slots, and secured to the ordinary breechings.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed I would have it under-
stood that what I claim is
In harness used for 'tandem' or 'four-in-haud' driving the use of one continuous
trace, or separate traces, whereby the disturbance or displacement (caused by the
variation in speed of the leader and wheeler) is obviated in the manner substantially
as herein specified and set forth.
