Improvements in Jointed Shaft Couplings.
I, FREDERICK WILLIAM LANCHESTER, of Cobley Hill, Alvechurch, in the County
of Worcester, Engineer, do hereby declare the nature of this invention to be as
follows:-
'
This invention relates to improvements in jointed shaft couplings and refers
more particularly to those couplings in which it is desired to transmit torsional
stress and at the same time allow a certain amount of angular and sliding move-
ment to the two portions of shafting to which the coupling is applied. The present
invention has for its object to simplify as far as possible the working parts and
to so arrange them that the same elements of mechanism that allow of the shafts
working at an angle to one another also permits freely of sliding movement.
In one mode of constructing a coupling in accordance with the present invention
I arrange on the extremity of one of the shafts a cylindrical vessel slotted intern-
ally on opposite sides and on the extremity of the other I attach a ball turned
to fit within the said cylinder and drilled transversely to receive a pin whose
extremities are planed down to fit into 'the slots in the cylinder and slide freely
therein. A coupling constructed as above described may be proportioned to
transmit any power desired and to allow within certain limits of both angular
and sliding movement to whatever extent required.
When the shafting is approximately vertical the lower portion is preferably
fitted with the cylindrical vessel which may then be filled with oil or other
lubricant and a loose lid may be fitted to prevent overflow.
The hereinbefore described coupling is especially useful in connecting from
the superstructure to the underframe of motor carriages and may be used either
for the power transmission or for the steering or other control mechanism.

Improvements in Jointed Shaft Couplings.
I, FREDERICK WILLIAM LANCHESTER of Cobley Hill Alvechurch in the County
of Worcester, 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:-
This invention relates to improvements in jointed shaft couplings and refers
more particularly to those couplings in which it is desired to transmit torsional

page_text: stress and at the same time allow a certain amount of angular and sliding move-
ment to the two portions of shafting to which the coupling is applied. The present
invention has for its object to simplify as far as possible the working parts and
to so arrange them that the same elements of mechanism that allow of the shafts
working at an angle to one another also permits freely of sliding movement.
The method of carrying my invention into effect is illustrated in the
accompanying sheet of drawings in which,
Figure 1 is an elevation of the improved coupling, and
Figure 2 a sectional plan on a b Figure 1.
In this mode of constructing a coupling in accordance with the present invention
I arrange on the extremity of one of the shafte A a cylindrical vessel B slotted
internally on opposite sides at EE and on the extremity of the other shaft C
I attach a ball 1 turned to fit within the said cylinder B and drilled transversely
to receive a pin F whose. extremities GG are planed down to fit into the slots EE
in the cylinder B and slide freely therein. A coupling constructed as above
described may be proportioned to transmit any power desired and to allow within
certain limits of both angular and sliding movement to whatever extent required.
When the shafting is approximately vertical the lower portion is preferably
fitted with the cylindrical vessel B as hereinbefore described which may then be
filled with oil or other lubricant and a loose lid H may be fitted to prevent overflow.
The hereinbefore described coupling is especially useful in connecting from
the superstructure to the underframe of motor carriages and may be used either
for the power transmission or for the steering or other control mechanism.
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:
1. In jointed shaft couplings the provision of a slotted sleeve rigidly attached
to the end of one shaft carrying within it the end of the second shaft which
rotates upon a pin whose ends ride in the slots of the said sleeve; as a means for
a limited angular motion in combination with a sliding adjustment while
transmitting torque or twist.
2. The improved shaft coupling hereinbefore described with reference to the
accompanying drawings.
