PROVISIONAL SPECIFICATION.
Improvements in Harness.
We GEORGE WILLIAMSON of 316 Cold Harbour Lane Brixton, Harness
Maker, and CONSTANTINE DE NEGRI of 68 Stamford Street Blackfriars, Engineer
both in London in the County of Surrey do hereby declare the nature of this
invention to be as follows:-
This our invention relates to a particular form of tug which may be either
attached to a short back-band to buckle both sides or may be used as draught ends
of pair horse traces.
The tug consists of a buckle, part of which has a slot which will allow a square-
shaped D piece to enter freely and which is connected with the said D piece by
sufficient leather to allow the shaft or bar bolt of the vehicle to be enclosed, so that
when buckled the D piece is held in the slot by passing the points of the back-
band through it.
When used as draught ends of pair horse traces it buckles round the bolt on the
splinter bar and in either case, should a horse fall, by withdrawing the points of
the back-band, or traces, as the case may be, the Ĺ piece is released and falls out
thus leaving the horse to rise.

COMPLETE SPECIFICATION.
Improvements in Harness.
We GEORGE WILLIAMSON of 5 New Cromwell Road, Luton in the County of
Bedfordshire, Harness Maker, and CONSTANTINE DE NEGRI of 68 Stamford
Street, Blackfriars in the County of London, Engineer, do hereby declare the
nature of this invention and the manner in which the same is to be performed to be
particularly described and ascertained in and by the following statement :-
This invention relates to certain improvements in harness and consists in the
construction and form and in the arrangements of the parts of tugs or shaft couplers
for back buckles and for trace ends, whereby the horse or horses may be readily
and quickly attached to a vehicle or released therefrom in case of accident, or at
any other time.
We will now proceed to further and fully describe our improvements in reference
to the accompanying drawings in which similar letters refer to similar parts.
On Sheet 1, Figure 1 is a complete front view showing back band A. belly
band C and shaft tugs S with our improved shaft tug buckles B; Figure 2 is a
side view of the same.
Figures 3 and 4 are respectively plan and side view of our invention as applied
to the ends of the traces T.
Our tug buckles used for shaft tugs or trace ends combined with buckles are
illustrated on Sheet 2, Figure 5 being a front view, Figure 6 a side view of same,
whilst Figures 7, 8 and 9 are respectively plan, side, and end views of the
D piece.
The buckle b is formed with a part having slot R, and 6' is the attachment for
fixing the harness; a D shaped piece D fixed to the outer end of each shaft tug S
or trace T is of a size adapted to pass freely through the said slot R in the
tupa B

page_text: On Sheet 3 we give a modification of our invention as applied to trace ends
doing away with the buckle part b. Figure 10 is a plan and Figure 11 a side view
of the trace ends;
Figures 12 and 13 are respectively plan and side view of slot piece, and Figures 14
and 15 are also respectively similar views of the square D piece.
On Sheet 4, Figures 16 and 17 are respectively plan and side views of our
invention as applied to traces where chains are in use, details being given on the
same sheet at Figures 18 and 19, which are respectively front and side view of
D piece with ring O attached, and Figures 20 and 21 are respectively front and
side views of the slot piece..
On Sheet 5 Figure 22 we show another way in which we apply the same pieces_
to chain trace ends, doing away with the ring O.
Figures 23, 24 and 25 are respectively a side view and two plans showing
another manner of applying our invention to pair horse traces, and with slight
modifications to single horse traces. Figure 26 shows an elevation of a multiple
slot piece, and Figures 27 and 28 are side and front views of the D piece
detached.
In all cases the D piece fixed to one part of the harness is to be passed through
the slot R in the tug or slot piece B fixed to another part of the harness, and it is
then secured therein by passing a point P, which may exist or be provided, through
the other end of the D piece, its object being to couple or secure the two separate
but co-acting pieces B and D aforesaid together, and be easily and instantly with-
drawn when required.
Figure 1 illustrates on the right the manner in which the backband point P is
used to pass through the inserted D piece behind the slot R in the tug B, thereby
embracing one of the shafts of a vehicle, whilst the uninserted piece Ď on the left
side illustrates how, when the point P has been withdrawn from it, it is immediately
released from the slot R in the tug buckle B; in a like manner Figure 3 shows by
the same letters, how the roller bolt E' on the half splinter bar E illustrated, may
be encircled by the trace end which is joined at b¹ to the tug buckle B, and fixed
by the D piece, slot piece, and point P on the right side, and how it may be released
by withdrawing the point P, on the left side.
We may here note that p indicates a protecting "safe" where required.
The modification Figure 10 is not only more simple than Figure 3, but has the
advantage of closing on the roller bolt in proportion to the strain put upon
the trace.
It will now be observed that the D pieces are in this case strung loosely on the
traces T, so as to slide thereon; and when one piece is passed through the slot R,
Figure 12 and fastened there by the point P the coupling will be as shown to right
of Figure 10, and, when the point P is withdrawn it will release the parts from
the roller bolt as shown on the left side.
Figure 16 illustrates a way of applying our invention to traces where chains are
in use; in these it will be seen that the D piece has a ring O attached to it, which
ring is strung on the chain whilst the hook H is hooked back to any link to suit
the length required, the slot piece Figures 20 and 21 being attached to the other
end of the chain and the point P disposed as shown.
We show on right hand side of Figure 16 the point P in place, and on the left
the chain released.
In the arrangement illustrated in Figure 22 the ring O is dispensed with and
the length of the chain is adjusted by the hook H in the usual way, viz. by being
hooked into any of the links 1, 2, 3, or 4, more or less as may be required or
desired, the method of releasing being identical with all the other trace ends already
described.
The last example we give here of the application of our invention is shown by
Figures 23, 24, 25, 26, 27 and 28 as employed for pair horse harness, H' indicating
the end leading up to the draught eye of the hame iron.
The frame B, Figure 26, consists of a multiple slot piece prepared to receive the

page_text: D piece, Figures 27 and 28. The D piece is passed through one of the slots R
according to the length required, and the point P attached to the trace T is passed
in front of the slot piece through the D piece end then through the series of loops
or a pipe loop whichever may be preferred.
The same style of slot-piece B only on a smaller scale is well adapted for use as
a trace and tug buckle for single horse vehicles.
Having now particularly described and ascertained the nature of this invention
and in what manner the same is to be performed we wish it to be clearly understood
that we do not confine ourselves to applying this invention in the exact manner
hereinbefore described but what we claim is :-
1. The improvement in harness consisting in the use of a point such as P for the
purpose of readily coupling together two separate but co-acting parts of the harness
in such manner that the coupling can be instantly released when required.
2. The improvement in harness consisting in the combination of a buckle having
a slotted part for receiving a D piece such as D wherein it is held by the point P
which is part of the back band or attached to the trace, substantially as and for
the purposes specified and illustrated in Figures 1 to 9.
3. The improvement in harness consisting of the combination of a slotted piece B
fixed to end of trace, a D piece adapted to slide upon the trace, and a point P
either fixed to the trace, or in any other position for securing the trace substantially
as specified and illustrated in Figures 10 to 20.
4. The improvement in harness consisting in the use of a multiple slot piece such
as illustrated in Figures 26 attached to the trace in combination with a D piece
such as illustrated in Figures 27 and 28 and the point P, substantially as set forth
in reference to Figures 23 to 28.
