PROVISIONAL SPECIFICATION.
An Improvement applicable to Wheeled Vehicles.
I, THOMAS HARGREAVES BRIGG, of Thornton Road, Bradford, Yorkshire,
Engineer, do hereby declare the nature of the said invention to be as follows :-
In wheeled vehicles fitted with a fore-carriage as ordinarily, the forc-carriage is
subject to constant vibratory movements about its central connection to the body
of the vehicle, cansed, inter-alia, by obstructions on or irregularities of the roadway,
and the motion is communicated, with a tendency to augment the lateral deviation,
to the connected draught-animal by the usual connections of the fore-carriage and
shafts, to which the draught animal is harnessed, tending to produce an unstable
feeling in and to distress the animal as it is thus being perpetually buffeted on its
sides and to minimise its utility and tractive efforts.
The object of this invention is to provide means of preventing this vibrating
motion of the fore-carriage from being communicated to the connected draught
animal or of materially lessening the communicated motion.
To this end, according to one modification, connect the shafts to the fore-
carriage by means of eye-bolts adapted with rubber or metallic springs through
which the bolt connecting the fore-carringe and shafts is passed, so that the
vibratory motion of the fore-carriage is more or less taken up by such intervening
springs, without being directly communicatod to the shafts as ordinarily.
According to another modification, I connect the eye-bolts usually attached to
the fore-carriage, to the ends of a plate spring, the centre of which is clipped or
bolted to the fore-carriage, the eye bolts passing through the ends of the spring
and the front part of the fore-carriage and being fitted with springs adapted to
take the said vibratory motion and prevent it from being communicated to the
shafts and connected draught animal.

COMPLETE SPECIFICATION.
An Improvement applicable to Wheeled Vehicles.
I, THOMAS HARGREAVES BRIGG, of Thornton Road, Bradford, Yorkshire,
Engineer, do hereby declare the nature of the said invention, and in what manner
the same is to be performed, to be particularly described and ascertained in and
by the following statement:-
In wheeled vehicles fitted with a fore-carriage as ordinarily, the fore-carriage is
subject to constant vibratory movements about its central connection to the body
of the vehicle, caused, inter alia, by obstructions on or irregularities of the roadway,
and the motion is communicated (with a tendency to augment the lateral deviation)
to the connected draught-animal, by the usual connections of the fore-carriage and
shafts, to which the animal is harnessed, tending to produce an unstable feeling in
and to distress the animal as it is thus being perpetually buffeted on its sides and to
minimise its utility and tractive efforts.
The object of this invention is to provide means of preventing the vibrating
motion of the fore-carriage from being communicated to the connected draught
animal or of materially lessening the communicated motion.
To this end, according to one modification, ride Figs. 1 and 2, respectively a
sectional elevation and a sectional plan, I connect the shafts 4, to the fore-carriage 5,

page_text: by means of eye-bolts 6, adapted in any suitable manner with rubber cushions or
metallic springs or equivalent cushioning or resilient parts 7, through which the
usual bolt 8, connecting the fore-carriage and shafts is passed, the parts co-acting
in such a manner that the vibratory notion of the fore-carriage will be more or
less taken up by such intervening cushions, springs or equivalent parts so as not to
be directly communicated to the shafts as ordinarily. The eye-bolts 6, may be
bolted or otherwise secured to the fore-carriage and shafts in any suitable manner.
According to another modification, cide Fig. 3, a plan view, I connect eye-
bolts 6*, such as those usually attached to the fore-carriage, to the end of a plate
spring 9, the centre part of which is clipped or bolted to the fore-carriage as at 10, the
eye-bolts 6*, passing through the ends of the spring 9, and the front part of the
fore-carriage, and being fitted with nuts 11, and springs 7*, adapted to take up
the said vibratory motion so as to wholly or nearly so prevent it from being
communicated to the shafts and connected draught animal as aforesaid.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
:-
1. In vehicles, the combination of a fore-carriage, shafts, and an elastic connection
of such parts operating to prevent or materially minimise the communication from
the fore-carriage to the shafts of lateral vibratory motion.
2. The modification hereinbefore described with reference to Figs. 1, and 2, of
the accompanying drawings.
3. The modification hereinbefore described with reference to Fig. 3 of the
accompanying drawings.
