COMPLETE SPECIFICATION.
Improvements in the Naves of Carriage Wheels.
We, ANATOLE LELONGT, and LOUIS LELONGT, of 121, Boulevard de
l'Hopital, Paris, in the Republic of France, Merchants, 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 and
accompanying drawing, that is to say :—
The improved nave has for its object to render the wheels to which it is applied
elastic, and to deaden the hard blow upon paved roads which the ordinary wheels
with fixed naves produce. The wheel being moveable in the improved nave, the
vibration and shaking of the carriage are considerably reduced, the liability to
breakage of the axles and springs is prevented, and considerable economy is
effected in the wear and tear of the entire carriage.
With the improved separate nave, the shape of the wheel is not in any way
different from those ordinarily used, so that even an experienced wheel-wright or
carriage builder will be unable to notice the construction of the interior of
the nave.
--
The nave may be made according to any of the three following methods :-
1st. A nave for carriages carrying three or four persons.
The nave A (as illustrated in Figure 1 of the accompanying drawing) is formed
in two parts; the spokes arranged between them are held together at the centre by
galvanized iron plates B upon each side of the spokes. These plates are firmly
attached to the nave by bolts C, and against the plates rest washers D of india-
rubber, having holes for the passage of the bolts and for the heads of the latter
and the nuts. Against these plates of indiarubber are fitted the two parts A of
the outer nave which are provided with small rings E of indiarubber opposite the
bolt heads and nuts.
The inner ends of the spokes rest upon a steel tube. F, inside which is another
tube of indiarubber G fitting upon the axle-box H which is provided with ears or
projections to prevent it from turning.
i
The iron rings I and J, whilst they hold the outer nave firmly, give at the same
time more or less elasticity to the wheel by the compression of the indiarubber.
The iron rings K fitted near the spokes enclose the indiarubber.
2nd. Figure 2. Naves for carriages carrying twenty to forty persons.
The principle of these is exactly the same as in the first form already described.
The reference letters A', B, C, D', E¹, F¹, G', H¹, I, J, K¹, being used instead
of A, B, C, D, E, F, G, H, I, J, K. The nave differs from the first form
described, only in the special axle-box H', which is regulated by means of the iron
ring L resting upon the indiarubber ring D'.
3rd. The invention may be applied to wheels of all kinds fitted with patent
axle-boxes,
The wheel is not less solid, its appearance is not altered, and it can be repaired
like other wheels.
The adjustment in the usual way of wheels having the improved nave is
unnecessary until the complete wearing away of the tyres, for by replacing the
teel tube F, the settling in of the wheel
can be readily corrected when
perceptible.

page_text: Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what
we claim is :-
The construction of the naves of carriage wheels with india rubber at the back
and front of the spokes, substantially as described and illustrated.
Dated this 21st day of May 1895.
