Improvements in Velocipedes.
nicated
I, ALEXANDER JAMES ELI of the firm of Hughes, Eli and Hughes, of
76 Chancery Lane, London W.C. Patent Agent, do hereby declare the nature of
renting (which invention has been
by Jean Lapovic
of Aire-sur-L'Ardour, France, Professor at the Professional School at that town)
ind in what manner the same is to be performed to be particularly described and
scertained in and by the following statement:-
My invention relates to improvements in velocipedes and has for its object to
dapt thereto mechanism which will reduce the shaking, vibratory or jolting
notion to which these machines are subjected particularly when travelling on rough
oads.

ind in what manner the same is to be performed to be particularly described and
scertained in and by the following statement :-
My invention relates to improvements in velocipedes and has for its object to
dapt thereto mechanism which will reduce the shaking, vibratory or jolting
notion to which these machines are subjected particularly when travelling on rough
roads.
In the accompanying drawings
Fig. 1 is a side view of a velocipede provided with my improvements.
Fig. 2 is a rear view of the machine.
Figs. 3 and 4 are details showing modifications of my invention.
Fig. 5 is a side view of a modified form of spring and
Fig. 6 a detail.
The main feature of my invention consists in the application of one or two
springs R. between the principal part of the frame A and the transverse piece D
connecting the two branches of the upper fork E K F, E¹ K¹ F¹.
Each branch has one of its extremities jointed at F or F1 to the corresponding
branch of the lower fork B while the other extremity is arranged to slide freely up
and down.
The lower fork B. is movable upon the crank shafts to which each branch is
jointed by means of a strap H.
For the purpose of increasing their rigidity these two branches are further
connected by a cross bar .J.
The extremities E K, E¹ K¹ of the upper fork pass through cylindrical
sleeves M, M connected together by means of a small shaft G. carried by the
prolongations L L' of the frame A of the machine (Figs. 2 and 6).
The spring used may either be a spiral spring or have the form shown in Fig. 5
that is to say consists of a number of thin steel strips arranged after the manner of
axle springs such as used for carriages; and I may further use one or two spiral
springs R.
In the first case the spring R Fig. 2 bears at its lower end against the transverse
bar D and at its upper end against the central part of the shaft G.
When two spiral springs are used they are coiled upon the lower part of the
ends E, K, E', K', of the upper fork and bear against the transverse bar D at one
end and against the sleeves M. M' at the other.
I may also make use of the arrangement shown in Fig. 4 in which only one
sleeve M is used being secured by means of two pins g. g¹ to the two branches P. P
of a fork formed integrally or otherwise secured in any suitable manner to the
frame A of the machine. The small springs s. scoiled on the upper part of the
ends E, K, E', K' between the sleeves M. M' and the nuts ll serve to deaden any
recoil due to a sudden expansion of the spring or springs R.
In the arrangement shown in Fig. 5, the two parts of the spring R are fixed at
their ends to two india rubber blocks n n' and the spring is provided centrally with
two straps t. t by means of which it is attached to the shaft G and to the
transverse bar D. respectively in accordance with the arrangement shown in
Fig. 2.
When the machine is mounted by the rider the spring R is first contracted and
[Price Ad

page_text: the whole frame is slightly lowered the machine being thus suspended in the same
manner as an ordinary carriage.
My improvements are applicable to all kind of velocipedes whether bicycles or
tricycles.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed I declare that what
I claim is.
I
In velocipedes the mode of suspension of the upper fork E, K, F, E', K', F¹
whereby the transmission to the rider of any jolting or vibration communicated to
the machine is greatly reduced in intensity substantially as herein described and
shown.
