improved Means for Transmitting Motion between Snaits or AxIUS.
I, BENONI CLOVIS VAGNIEZ, of 14, rue Lemerchier, Amiens, (Somme), France,
Yeast Merchant, do hereby declare the nature of this invention to be as follows:-
This invention relates to means for transmitting motion between two parallel shafts
whose distance apart may vary at each moment and to a new system or construction
of toothed wheels in which the teeth are curved in two different planes. This system
or construction of wheels enables motion to be transmitted between shafts which do
not remain parallel while their distance apart varies.
The accompanying drawing represents by way of example, a part of a steam
carriage fitted with means according to this invention by which the motion is trans-
mitted from the crank shaft to the driving axle by means of toothed wheels. It is to
be understood that chains or belts may be substituted for the wheels.
Fig. 1 is a side elevation.
Fig. 2 is a plan, partly in section, the section following the line a b c Fig. 1.
Fig. 3 is an end elevation.
Fig. 4 is a perspective view of a part of a toothed wheel according to this
invention.
Fig. 5 is a plan of the same.
Fig. 6 is a cross section.
T is the frame work of the carriage, R the spring, P is the crank shaft which gives
rotary motion to the toothed wheel D fixed on it. In its turn this wheel drives
the wheel B fixed to the driving wheel A by means of the intermediate toothed
wheel C. E&F are easy fitting rods or arms supporting the shaft G of the wheel C.
N is the horn plate.
In case of flexure of one of the springs R by a shock or any other cause the frame T
and engine crank shaft P which are connected together take the position as indicated
in Fig. 3 and in dotted lines in Fig. 1. The arms or rods E F permit the shaft G to
lower itself to G₁ at the same time keeping it parallel to the shaft P.
To permit of this parallelism the shaft G ends in a ball joint working in the arm
or rod E. In this movement the wheel C becomes displaced from the vertical plane
by sliding over the wheel B, this sliding being permitted by the peculiar form of the
teeth which are constructed with curves of the same radius. To aid and at the same
time to limit this sliding movement, which necessitates that the wheels B & D shall
be of increased width, the wheel C is mounted on a ball or spherical bearing on its
shaft G; this arrangement permits of the three wheels placing themselves in different
planes as indicated in Fig. 3.
If the two springs are flexed equally the articulated system of rods bend symme-
trically on both sides, and in that case all the shafts remain parallel among themselves.
The distance apart of the shafts O & P is altered, but the engagement of the gearing
remains the same, since the intermediate wheel is of a diameter greater than the
distance between the wheels B & D.

page_text: Fig. 6 is a cross section.
T is the framework of the carriage, R the spring, P is the crank shaft which gives
rotary motion to the toothed wheel D fixed on it. In its turn this wheel drives the
wheel B fixed to the driving wheel A by means of the intermediate toothed wheel C.
E & F are easy fitting rods or arins supporting the shaft G of the wheel C. N is
the horn plate.
In case of flexure of one of the springs R by a shock, or any other cause, the
frame T and engine crank shaft P, which are connected together, take an inclined
position such as indicated in Fig. 3 and in dotted lines in Fig. 1. The arms or
rods E, F, permit the shaft G to lower itself to G¹, at the same time keeping it.
parallel to the shaft P.
To permit of this parallelism the shaft G ends in a ball joint working in the arm or
rod E. In this movement the wheel C becomes displaced from the vertical plane by
sliding over the wheel B, this sliding being permitted by the peculiar form of the
teeth which are constructed with curves of the same radius. The teeth of the wheels
are curved in two directions as shewn, both curves being struck with a radius equal
to the radius of the intermediate wheel. To aid and at the same time to limit
this sliding movement, which necessitates that the wheels B and D shall be of
increased width the wheel C is mounted on a ball or spherical bearing on its shaft G ;
this arrangement permits of the three wheels placing themselves in different planes
as indicated in Fig. 3.
If the two springs are flexed equally the articulated system of rods bend symmetri-
cally on both sides, and in that case all the shafts remain parallel among themselves.
The distance apart of the shafts O & P is altered, but the engagement of the gearing
remains the same, since the intermediate wheel is of a diameter greater than the
distance between the wheels B & D.
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 :-
The use for transmitting motion between shafts or axles of the hereinbefore
described system of articulated rods or arms in combination with toothed wheels with
doubly curved teeth.
