Year: 1880

page_text: I JOHN WHITTINGHAM of the Cross, Nantwich in the County of Chester, seok
leave to amend the Specification of Letters Patent, No. 3860 of 1880, as shown in
red ink in the copy of the original Specification hereunto annexed.
My reasons for making this amendment aro as follows:-
"
That I wish more clearly to describe the construction of the universal joint, and
to limit my claim to the form of universal joint so described, viz.: the "gimbals
form, and at the same time to correct some inaccuracies in the Drawing.
Page, 2, line 9, strike out words "I fix a" to the words "chain wheel" line 13,
and substitute the following:-for the attachment of the steering wheels, I connect
them with the engine or vehicle through the medium of a universal joint of tho
kind commonly known as gimbals" such as is used for suspending ships"
compasses, and chronometers in their cases, I construct my universal joint of threo
concentric rings. The smallest and innermost ring is rigidly keyed or attached on
the centre of the axle of the steering wheels, which axle may be either solid or
hollow, and is furnished with two short studs or trunnions, which work in bearings
in the second ring, the said studs or trunnions being opposite to each other at the
extremities of a diameter of the ring. The second ring is supported in the third
ring by two studs in the like manner, the studs in the second ring being at the
extremities of a diameter at right angles to the studs in the first ring. The third
or outer ring is supported by three or more grooved pulleys or rollers, which are
supported in suitable bearings in the frame of the engine or vehicle, and thus form
an antifriction bearing for the ring. The central portion of the periphery of tho
outer ring is formed as a pitch chain wheel, or is furnished with cogs as a spur
wheel.
Insert after the words "the engine" on line 14 page 2, the following:-Tho
groove in the pulleys or rollers allows the necessary spaco for the pitch chain or for
the cogs. If preferred, the universal joint above described may be attached to a

page_text: countershaft, and the steering axle connected therewith by pitch chains and wheels-
or in any other suitable manner.
Strike out the words "The particular" line 15 page 2 to end of line 18.
Line 29 page 2, after word "joint," insert a full stop and the following words:-
This universal joint is formed of an innermost ring a, keyed on centre of axlo M
of steering wheels, and supported within a second ring 6 by two studs or
trunnions a¹ a', this second ring being in its turn supported within the third or
outer ring c by two studs or trunnions b¹ b¹ at right angles to the studs a¹ a¹. The
third or outer ring c, as shown.
Strike out the word "which," line 29, p. 2, after the words "universal joint."
Strike out lines 42, 43, and 44, and substitute the words:-of such Invention
being the application of a universal joint and fittings of the kind herein described,
and commonly known as "gimbals," to enable all the wheels of the engine or other
vehicle to be used as driving wheels, and at the same time to steer in any
direction.

JOHN WHITTINGHAM of the Cross Nantwich in the County of Chester
"IMPROVED STEERING AND DRIVING ARRANGEMENTS FOR TRACTION ENGINES
AND OTHER VEHICLES."
My Invention for steering and driving traction engines and other vehicles
consists mainly of the following arrangements:-―
Instead of the turntable at prosent employed in engines and vehicles, I fix a frame
under the fore part of the engine or vehiclo, in which frame are placed three or
more grooved revolving pulleys. These pulloys support aud keep in its place an
outer ring of a universal joint. This outer ring is either a toothed wheel or a
pitch chain, and is driven either by a pitch chain or gearing from the main shaft
of the engine.
The above arrangements would be suitable for ordinary waggons or any kind of
vehicle requiring a turntable at the front."
The particular point or feature of this Invention is being able by a universal
joint and fitting as before set forth to use all the wheels of the engine as driving
wheels, and at the same time to steer in any direction.

"IMPROVED STEERING AND DRIVING ARRANGEMENTS FOR TRACTION ENGINES

My Invention for steering and driving traction engines and other vehicles
consists of the following arrangements :
-
Instead of the turn-tablo at present employed in engines and vehicles fixa
frame-under the fore part of the engine or vehicle in which-frame-are-placed three
or more grooved revolving pulleys. These pulleys support and keep in its place-nu
outer ring of a universal joint. This outer ring is either a toothed wheel or a
_pitch-chain-wheel, for the attachment of the steering wheels, I connect them with
the engine or vehicle through the medium of a universal joint of the kind commonly
known as "gimbals" such as is used for suspending ship's compases and
chronometers-in-their-cases, I-construct-my-universul-joint-of-three-concentric-
rings. The smallest_and_innermost_ring_is_rigidly_keyed or attached on the
centre of the uale of the steering wheels, which axle may be either solid or hollow,
und is furnished with two short studs or trunnions, which work in bearings in
the second ring, the said studs or trunnions being opposite to each other at the
extremities of a diameter of the ring. The second ring is supported in the third
riny by two studs in the like manner, the studs in the second ring being at the

or outer ring is supported by three or more grooved pulleys or rollers which are
supported in suitable bearings in the frame of the engine or vehicle, and thus form
an antifriction bearing for the ring. The centre portion of the periphery of the
outer ring is formed as a pitch chain wheel, or is furnished with cogs as a spur
wheel and is driven either by a pitch chain or gearing from the main shaft of the
engine. The groove in the pulleys or rollers allows the necessary space for the pitch
chain or for the cogs. If preferred, the universal joint above described may be
attached to a countershaft, and the steering axle connected therewith by pitch chains
and wheels, or in any other suitable manner. The above arrangements would be
suitable for ordinary waggons or any kind of vehicle requiring a turntable at the
front. The particular point-of-feature--of-this-Invention--is--being--able--by-a
universal joint-and-fitting as-before-set forth-to-use-all-the-wheels-of-the-engine-as

Having thus far described the nature of the said Invention, and incidentally
intimated in what manner the same is to be performed I will now proceed by
reference to the accompanying Drawings to further and particularly describe and
ascertain in what manner the same is to be performed or carried out in practice.
