Improvements in Carriage Shafts.
I, GUSTAVE XAVIER TAUTAIN, of 206 Rue Lafayette Paris, in the Republic
of France, Engineer, 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 :-
My invention relates to carriage shafts.
In the accompanying drawings,
Figure 1 is a longitudinal section, showing the arrangement of one of the
improved carriage shafts, the other shaft being exactly similar.
Figures 2, 3, 4 and 5 are detail views.
As shown in these figures the wood of the shaft A is divided into three
sections A A A³.
The left-hand extremity of the section A' is fitted into a piece a of malleable
cast-iron, of which Figures 2 and 3 show respectively an elevation and a plan.
Bolts or pins a¹ and a consolidate this connection and the extremities of a bar a³
on the said piece a will, when the shaft is raised, form an abutment as usual upon;
the corresponding mouth.
The section A' is pierced with a longitudinal hole, the diameter of which
varies so as to receive a notched washer at and a helical spring a', these two parts
being traversed by a steel rod a' with whose extremities forming rings are engaged.
on the right hand side the last link of a chain a' and on the left hand side a
cottar a held by the notch in the washer a*.
The section A is also pierced with a longitudinal hole, the diameter of which
varies so as to receive a steel rod a', with whose extremities forming rings are
engaged on the right hand side the last link of a chain a¹0 and on the left hand
side a band chain link a" which is attached to the above mentioned chain a³.
The sections A and A' are articulated together by means of two rings a
and a of malleable steel fixed upon the wood of the said sections by screws or in
any other suitable manner, and of which Figures 4 and 5 are respectively an
elevation and a plan. As shown in these figures the rings a¹ and a" are of the
form of a hollow cylinder and present one in relief and one in intaglio, trunks of a
quadrangular pyramid designed to fit one into the other when they are juxtaposed
as in Figure 1. It will be readily understood that a similar articulation permits
of the flexion, to 90 degrees and in all directions, of one of the two sections which
it unites relatively to the other.
The section A is likewise hollowed out to receive the right hand extremity of
the chain a¹, this extremity terminating in a long link a" which, after traversing
a washer a¹, receives a cottar a¹. As regards the articulation of the sections a³
and a³ it is obtained by means of two rings a" and a which are exactly similar
to the above-mentioned rings a" and a³, the ring as forming moreover a point
of support for a piece a of malleable cast iron which is fastened by means
of screws upon the wood of the section A* and serves as usual to receive and
hold the strap of the saddle.
I effect the mounting of my improved articulated shaft as follows:
The rod a provided with the chain a' is passed into the hole of the separate
section A through the right hand extremity of this section, the left hand
extremity of the said rod a' is moved outside the left hand extremity of
the said section A' so 88 to receive successively the helical spring a', the
notched washer a* and the cottar as, after which the rod as is moved to the
right again together with the several parts which it traverses or retains, and
by the aid of any appropriate device the helical spring a' is powerfully com-
[D7]

rod a to pass a sufficiently long distance from the right hand extremity of the
section A and facilitating the next operations.
The rod a provided with the chain a¹ is then passed into the hole in the
separate section A' through the right hand extremity of this section, and the
left hand extremity of the said rod a is moved outside the left hand extremity
of the said section A' so that through the medium of the band chain link a
the last ring of the said rod a' can be connected with the last link of the
chain a'. After this the chain a¹ is pulled to the right so that a sufficiently
great length will pass from the right hand extremity of the section A' at the same
time as the two rings a" as are fitted together.
The free extremity of the chain a¹0 is then engaged with the cavity of the
section A (the part a of which is supposed to be removed) and the long link a¹
receives the cottar a after it has passed through the washer a", then the
part a is put in its place and the two rings a alk are fitted together, where-
upon the device which holds the helical spring a compressed in the cavity of
the section A' is withdrawn, which permits the helical spring a to expand to its
original form and consequently exert the desired tension upon the whole of the
interior flexible armature of the articulated carriage shaft.
I may vary at will the forms, dimensions, proportions and materials employed
in so far as these variations do not affect the characteristic features of my
invention.
Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, 1 declare that what
I claim is :-
The improved articulated carriage shaft, substantially as hereinbefore described
with reference to the drawing.
