Complete Specification Left, 1st Sept., 1892-Accepted, 12th Nov., 1892
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 certain improvements in car-axles.
It consists in dividing the axle near the centre and in a peculiar sleeve and
coupling by which the two parts are held together and allowed to rotate inde-
pendently of each other.
Referring to the accompanying drawings for a more complete explanation of my
invention,
Figure 1 is an exterior view of my coupling.
Figure 2 is a section of the same.
A A are the two parts of an axle, which is divided in the centre.
These parts
have holes bored in the ends for a short distance, and a corresponding pin B is
adapted to enter the holes, so as to hold the two parts of the axle exactly in line
while allowing them to turn freely.
Around each part of the axle, near these meeting ends, is turned a groove or
channel D, for the purpose of receiving the collars E of the sleeve F. This sleeve
is split longitudinally into two parts, so as to facilitate fitting it upon or taking it off
the axle. It is made of considerable length in the form of a double cone, having
the greatest thickness and strength at the centre. It is bored out so as to exactly
fit the axle and is provided with the collars. E, as before described, to fit the
grooves D, made around the axle near the meeting ends. When the two parts of
the sleeve have been applied to the axle, they are retained in place by the hollow
conical collars G, which are fitted to surround the two halves of the inner sleeves
and clamp them closely together upon the axle. The outer collars G have flanges H,
through which holes are made for the introduction of bolts I, and by the aid of
these bolts the two collars are drawn toward each other, their inner surfaces fitting
over the outer conical surfaces of the inner cones, and thus clamping them strongly
together and upon the axle, at the same time giving great strength to this central
divided portion of the axle, while allowing the two parts to turn freely with
reference to each other, the object being to allow either of the wheels which are
fixed to the opposite ends of the axle to turn independent of the other, as when
passing around curves.
The double cone-shaped sleeve with the inclosing conical clamping collars and
the pin-and-socket connection of the abutting ends of the axle form a powerful
supporting truss, which overcomes any objection of lack of strength in the
structure

page_text: Having now particularly described and ascertained the nature of my
said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. The two part axle having abutting ends with holes 'bored centrally in them
and a guide-pin projecting into the holes, a two part sleeve surrounding the
meeting ends of the shafts, having inwardly projecting collars, grooves formed in
the axles, into which said collars fit, and the exterior collars by which the sleeves
are clamped together and retained upon the axle, substantially as herein described.
2. A two part axle with abutting ends, an axial pin-and-socket connection
between the ends, by which a movable connection is made between the two, circum-
ferential grooves around the. adjacent meeting ends of the axles, a longitudinally
divided sleeve, the exterior of which forms a doubie cone and the interior is formed
to fit the axle, and having interior collars which fit the annular grooves of the
axle, exterior conical collars fitting the conical surfaces of the sleeves, with flanges
upon their inner ends, and bolts by which these flanges are drawn toward each
other, substantially as herein described.
