Improvements in Carriage and similar Wheels.
I, EDWARD THOMAS HUGHES, of 5 Chancery Lane, London, W.C., Patent Agent
do hereby declare the nature of this invention (a communication from Carl Theodor
Wollmann of Berlin in the German Empire Engineer and in what manner the saine
is to be performed, to be particularly described and ascertained in and by the following
statement :-
11
My invention relates to improvements in carriage wheels, or wheels, for vehicles
of all kinds and has for its object to relieve the axle of the shocks, caused by the
rotation of the wheel, and to transfer the same to the spokes, thus utilizing the
shocks as a motive power, and reducing the inertia to a minimum.
Figure 1 is a sectional elevation of the wheel.
Figure 2 is a section of the top-half of the nave with spokes connected with it.
Figure 3 is a side elevation of the protecting spokes with details.
My improved wheel, is constructed with five sets of spring spokes which are
connected to the nave in the following manner :-
Over the axle box A four rings a. b. c. d are placed and held in position by the
flanges of the two tubes B. These rings a bed are made of suitable material and
provided with packing, so as to keep the rings a certain distance apart, thus forming
the spaces or chambers e, f, g. Into these chambers or spaces the sets of spokes are
fitted, the middle chamber being larger than the other two."
When the spokes are all fixed in the nave the whole is fastened together by means
of eight bolts C.
The middle spokes D are fixed in the chamber F. Outside the nave a loop N is
formed in the spoke and then the spoke is carried in a curve to the rim of the wheel F,
and at the rim another loop G is formed, and then the spoke brought back to the
chamber of the nave.
The loop G at the rim can be dispensed with if desired.
At both sides of the middle spokes, the spokes H are arranged (in a set consisting
of four or any multiple of four) and these spokes are held in the side chambers e & g
by means of the bolts C, and describe a logarithmetic curve round the nave, until
they reach the rim F to which they are attached.
On each side of the interior spoke arrangement above described, the wheel is
provided with eight spokes T, which protect the interior spokes and serve to balance
the wheel The extremities of these spokes T rest upon the bulged end K of the tubes B,
and being set up, are held in position by the pins K¹. These spokes T, after forming
the loop N are carried to the rim F. On either side of the spokes T, the spokes M
are arranged, but these spokes do not proceed any further than the ring O, which
passes through the loops N formed by the spokes T. The spokes M serve thus to
strengthen the spokes T at the loop N.
As
The ring O takes the shocks from the axle and also transfers them to the spokes T,
and to the spokes Q which go from the ring O at the point P, to the rim F.
all the spokes end in the rim Fit is advisable to make the rim of a semitubular section ;
the various parts can be jointed together in any suitable manner.
Having now particulary described and ascertained the nature of my invention
and in what manner the same is to be performed, I declare that what I claim is:
A carriage wheel possessing the following characteristics :
An arrangement of five sets of spokes, which serve to transmit the radial shocks
to the other spokes, the said middle spokes D after having a loop twiested in them, are
carried to the rim F and with or without another loop brought back to the nave
chamber. On either side of these middle spokes D, a set of spokes H (consisting

page_text: of four or any multiple of four) is arranged, which spokes EI are fixed in the nave
chambers eg and are carried to the rim in logarithmetic curves, thus serving to
convert the shocks on the wheel, to a power conducive to rotary motion.
In connection with the above the employment of the protecting spokes T, with or
without the spokes Q, such spokes T being attached to the bulged end of the tube K,
at their one extremity and to the rim F at the other, and supported by the spokes Q
and the ring O, which latter passes through the loops formed by the spokes T, for the
purpose of retaining the impetus caused by the middle and side spokes, and balancing
the wheel, in order to utilise the shocks on the rim, as a motive power.
