Year: 1877

page_text: LETTERS PATENT to Marcus Fenton and Bagshaw Cockayne, both of Sheffield,
in the County of York, Steel Manufacturers, for the Invention of "IMPROVE-
MENTS IN SECURING WHEELS AND PULLEYS TO THEIR AXLES."
Sealed the 6th October 1877, and dated the 3rd May 1877.
PROVISIONAL SPECIFICATION left by the said Marcus Fenton and Bagshaw
Cockayne at the Office of the Commissioners of Patents on the 3rd May
1877.
MARCUS FENTON and BAGSHAW COCKAYNE, both of Sheffield, in the County of
York, Steel Manufacturers. "IMPROVEMENTS IN SECURING WHEELS AND PULLEYS
TO THEIR AXLES."
Our Invention has for its object the securing of wheels of railway carriages and
wagons, colliery wagons, and other similar vehicles, fly wheels, pulleys, and other
mechanical wheels to their axles or shafts, and for the ready means of disengaging
and replacing the same, and we attain this object in the manner herein-after
described.
In carrying out our Invention, as applied to the wheels and axles of colliery
wagons, for example, in which the wheels are by preference made of cast steel, and
revolve with the axle, we construct the boss of the wheel of sufficient diameter on
one side to allow of a recess being cast or otherwise being formed in it of a square,
octagon, or other shape, corresponding in shape and depth to a collar formed on the
axle.
The hole through the wheel is by preference round, and the end of the axle fits
into it in the usual manner. To retain the wheel in full contact with the collar of
the axle a washer or plate made solid or in parts is fitted over the axle, and on the
contrary side of the collar to that on which the wheel is fitted, and it is secured to
the face of the wheel boss by screws, bolts, and nuts, or other similar appliances.
By a slight modification this arrangement may be altered to suit axles and wheels
having inside or outside bearings.

the said Marcus Fenton and Bagshaw Cockayne in the Great Seal Patent Office
on the 29th October 1877.
MARCUS FENTON and BAGSHAW COCKAYNE, both of Sheffield, in the County of
York, Steel Manufacturers. "IMPROVEMENTS IN SECURING WHEELS AND PULLEYS
TO THEIR AXLES."
Our said Invention has for its object securing the wheels of railway carriages
and wagons, colliery wagons, and other similar vehicles, fly wheels, pulleys, and
other mechanical wheels to their axles or shafts in such a manner as to afford ready
means for disengaging and replacing the same, and we attain this object in the
manner herein-after described, reference being had to the Sheet of Drawings hereunto
annexed.
Figures 1 and 2 of our Drawings illustrate the application of our said Invention
to a wheel such as is used in colliery wagons, for example, fitted to rotate with the
axle upon which it is carried, Figure 1 being a vertical section, and Figure 2 a side
elevation of the same; Figures 3 and 4 are similar views to Figures 1 and 2 of a
wheel fitted to rotate upon the axle, and having our said Invention applied
thereto.
The same letters of reference indicate corresponding parts in all the Figures.
Referring to Figures 1 and 2 of the Drawings, the wheel A, which is by preference
made of cast steel, and is intended to revolve with the axle B, is constructed with a
boss C of sufficient diameter on the inner side to admit of a recess being cast or
otherwise formed therein of a square, octagonal, or other shape corresponding to a
collar D formed on the axle B.
The hole formed in the boss C of the wheel for the reception of the end E of the
axle is by preference round, and the end of the axle is made to fit into it in the
usual manner.
The wheel A is maintained in contact with the collar D on the axle
by means of a washer or plate F, made either in one piece, as shewn, or in parts,
and fitted on to the axle on the opposite side of the collar D to that on which the
wheel is fitted, and the plate is secured to the boss C by means of bolts and nuts G,
as shewn, or by other suitable fastenings capable of being readily released for the
purpose of detaching the wheel from the axle when required.
When the Invention is applied to wheels intended to revolve upon their axles, as
in the example, Figures 3 and 4, the collar D upon the axle B and the recess in the
boss C for its reception are made of a cylindrical form, the washer or plate E for
securing the wheel upon the axle in this case being caused to revolve upon the axle
with the wheel.
The Drawings illustrate the Invention as applied to the securing of wheels of
vehicles only, but it is obvious that it is equally applicable for securing the wheels
and pulleys employed in machinery on to their shaft or axles.
Having now described and particularly ascertained the nature of our said Inven-
tion, and the manner in which the same is or may be used or carried into effect, we
would observe in conclusion that what we consider to be novel and original and
therefore claim as the Invention secured to us by the herein-before in part recited
.Letters Patent is, securing wheels and pulleys to their axles or shafts so as to render
them capable of being readily disengaged therefrom when required, substantially in
the manner herein-before described and illustrated by the accompanying Drawing.
In witness whereof, we, the said Bagshaw Cockayne, on behalf of Marcus
Fenton and myself, have to this our Specification set my hand and seal,
the Twenty-second day of October, One thousand eight hundred and seventy-
BAGSHAW COCKAYNE. (L.S.)
