PROVISIONAL SPECIFICATION left by the said William Robert Lake at the
Office of the Commissioners of Patents on the 30th September 1881.
WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, and Co., Patent Agents,
Southampton Buildings, London. "IMPROVEMENTS IN THE CONSTRUCTION OF
METAL WHEELS FOR VEHICLES." [A communication from abroad by Leopold May,
of Ungarisch Ostra, Austro-Hungary.]
This Invention relates to metal wheels for vehicles, a wheel constructed according
to my Invention being made of wrought iron or steel, and the nave or hub being
provided with an axle box which may be either interchangeable or fixed; or in
some cases the said wheel may be used without an axle-box.
In carrying the said Invention into practice I provide a tube of sheet iron, upon
the outer periphery of which at each end thereof is rivetted a ring made of angle-
iron, and on the inside of the said tube there are two corresponding rings, likewise
made of angle-iron.
The same rivets pass through the outer and the inner rings and through the
tube.
The axle box, when one is used, is inserted within the inner periphery of the
two inner rings in such a manner that a recess or notch in a ring which is provided
on the wider end of the box passes over a pin firmly fixed upon the corresponding
inner angle ring, and thus any rotation of the axle box is prevented; the tapered
or narrow end of the latter is screw-threaded upon the outside thereof, and by
means of a screw threaded nut fitting upon this end the box may be secured tightly
in its place; a screw is provided to prevent this nut from becoming loose.
The axle-box can be removed with great facility when the aforesaid nut is
unscrewed.

page_text: The spokes of the wheel are rivetted securely at their inner end to the said
exterior angle-iron rings, and at their other or outer end are rivetted between two
metal hoops which are L-shaped in transverse section. At the inner or nave end
one spoke is rivetted to the outer angle-iron ring which is on one side of the tube,
and the next one to the outer ring on the other side, and so on, and thus a broad 5
bearing surface is produced which considerably increases the resistant power of the
wheels as is well known. It is evident that the spokes may be placed differently;
other than angle-iron may be used, or I may employ single angle-iron (this bringing
the spokes into one line) or instead of the angle-iron rings iron brackets or pieces
of any convenient shape may be placed lengthwise upon the aforesaid tube, to 1
which brackets or pieces the spokes may be secured. Upon or over the two angle-
iron or L-shaped hoops an ordinary iron tyre is placed and fixed by a few rivets,
screws, or otherwise, and when worn out is easily replaced.
It is obvious that steel may be used instead of iron when desirable.

WILLIAM ROBERT LAKE, of the Firm of Haseltine, Lake, & Co., Patent Agents,
Southampton Buildings, London. "IMPROVEMENTS IN THE CONSTRUCTION OF
METAL WHEELS FOR VEHICLES." A communication from abroad by Leopold
May, of Ungarisch Ostra, Austro-Hungary.
This Invention relates to wheels for vehicles, the naves of which wheels are
made of wrought iron, steel, or other malleable metal.
Referring to the accompanying Drawing,
a is a tube of sheet iron, upon the periphery of which at the ends thereof are
rivetted rings b, 61, made of angle iron, and on the inside of the said tube are fixed
two corresponding rings c, c', also made of angle iron. The same rivets pass
through the outer rings b, b', and the inner rings c, c', and also through the tube a,
thereby preventing any displacement of the nave, a pin or stud i being provided
on the ring c or c which catches in a recess or notch in the axle-box d; or the
'said box may be provided with pins or the like which catch in corresponding
notches on the angle iron ring so that the axle box cannot be moved or displaced
in the wheel; the axle-box is secured at its front end by means of a screw nut
and a suitable screw-thread, and a set-screw 9 prevents the loosening of the nut h;
or the said axle-box may be secured by any other suitable means.
The replacing
of a damaged axle-box is therefore easily and speedily effected.
The spokes E of the wheel are fixed in any known manner at one of their ends
to the outer angle iron rings b, b, their other ends being secured between the two
metal hoops ff. It is evident that the spokes may be placed in other ways than
that shown in the accompanying Drawing; instead of the angle iron, other shapes
of iron may be employed, and the wheels may be made without removable axle-
boxes if desired.
The tyre of the wheel is fixed in any known manner to the two hoops which
are preferably made of angle iron, but may be made of various shapes and of other
malleable metal.
Having thus fully described the said Invention as communicated to me by my
foreign correspondent, and the manner of performing the same, I wish it understood
that I claim,
A wheel whose nave is constructed entirely of iron, steel, or other malleable
metal, and is composed of a tube and rings of angle iron or other metal picces,
substantially as specified.
In witness whereof, I, the said William Robert Lake, have hereunto set my
hand and seal, this Twenty ninth day of March, in the year of our Lord
One thousand eight hundred and eighty two.
