IMPROVEMENTS IN THE CONSTRUCTION OF NOISELESS WHEELS SUITABLE FOR RAILWAY PLATFORM TRUCKS AND SIMILAR VEHICLES
Year: 1884

page_text: I, WILLIAM MARTIN of 19 Silver Street Manchester in the County of Lancaster,
Fustian Cutter, do hereby declare the nature of my Invention for IMPROVEMENTS
IN THE CONSTRUCTION OF NOISELESS WHEELS SUITABLE FOR RAILWAY PLATFORM
TRUCKS AND SIMILAR VEHICLES to be as follows :-
I cast a wheel in metal with a flange.
I secure to the side of such wheel and against such flange sections of wood, by
passing bolts through the same, and by means of nuts secure a loose flange on the
inside of the wheel-such sections of wood are placed grain end up, as per rough
drawing.
The same may be applied to larger wheels, or pullies as before named.

page_text: I, WILLIAM MARTIN of 19 Silver Street Manchester, in the county of Lancaster
Fustian Cutter do hereby declare the nature of my invention for IMPROVEMENTS
IN THE CONSTRUCTION OF NOISELESS WHEELS, SUITABLE FOR RAILWAY PLATFORM
TRUCKS & SIMILAR VEHICLES and in what manner the same is to be performed,
to be particularly described and ascertained in and by the following statement :—
I construct a wheel with the outer rim or edge formed of timber, end grained
on, dovetailed and fitted between metal flanges: I make the centre of the wheel
of any convenient form or pattern, the outer edge being flanged or angular shaped:
On this angular seating I fit the end grained timber blocks, so that every alternate
block shall form a dovetail or rebate for the intermediate block: When the said
blocks are fitted in their places, I secure them to the wheel by means of a loose
metal ring or flange corresponding to the fast flange, and placed on the opposite
side: I then pass bolts through the two metal flanges and the intermediate wood
blocks, and the said bolts being tightly screwed, the wood blocks are held firmly
in position, and form the outer rim or tyre of the wheel.
The wood blocks may project beyond the metal flanges to a greater or less
extent as desired, or one or both of the flanges may project to serve as a guide
if the wheel is required to run on rails, or for other purposes: The wood blocks
used in the construction of such wheels as above described may be hardened by
being compressed similarly as wood keys that are used for railway chairs, or
by other process.
In order that my invention may be fully understood, I now refer to, and
describe the accompanying sheet of drawings, similar letters being shown on
similar parts through the several views.
Fig. 1 is a side view of wheel complete: Fig. 2 is an end view of the same:
Fig. 3 is a side view of wheel with washer or flange removed Fig. 4 is a section
of wheel through the centre: a. represents the wheel skeleton, b, the washer or
flange, c, the wood blocks forming rim, d, the bolts holding the blocks in position.
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
1st The construction of a wheel, the centre part of which may be of any shape
or pattern, but with the outer rim or edge, made of any suitable timber, in sectional
blocks, so that every alternate block shall form a rebate or dovetail for the inter-
mediate block, the outward pressure on the rim or periphery of the wheel thereby
causing the blocks to tighten and fit closely together and form a perfect wooden
rim or tyre for a wearing surface: substantially as shown and described.
2nd The construction of a wheel as above described, with the said wood blocks
projecting to a greater or less extent as desired beyond the metal flanges within
which the blocks are placed, or with one or both of such flanges projecting beyond
the wood blocks, so as to serve as a guide, if required to run on rails, or for other
purposes.
