An Improved Split Wheel having a Rubber or Composition Tyre, for
Use on Trolleys, Barrows and like Carriages.
I, ALFRED ADAM BAYLISS, of Madresfield, Beeches Road, West Bromwich, in
the County of Stafford, Hardware Merchant, do hereby declare the nature of this
invention to be as follows:-
My invention relates to wheels for trolleys barrows and like carriages having
india rubber or composition tyres. In these wheels it is an advantage to have
the wheels split to facilitate the fixing and removing of tyres. My invention
is a split wheel.
In the drawing C and D form the two main parts of the wheel. E, E, two
segments of an interruption screw, somewhat similar to the breech block of a
gun, F' a thin metal key bent over at F 1, G the tyre, H the boss of C and I the
boss of D.
The use of the wheel is as follows-The tyre G is first fixed on C, the boss I
of D,
then inserted through C until the screwed segments E, E, are in position
for engaging, the wheel parts C and D are then turned in opposite directions
with the result that the wheel is locked in the position shewn in the drawing
and the tyre firmly secured.
The key is then inserted as shewn in any one of the spaces left vacant between
the screw segments and driven through the hole provided in D, the key is then
bent over as at F1, and thus secures the wheel against coming unlocked when
in use.
To suit wheels of various diameters, the pitch of the screw segment may be
varied, also increased or varied to any suitable number of threads or segments.
The tyre may also be made of any suitable shape.

An Improved Split Wheel having a Rubber or Composition Tyre, for
Use on Trolleys, Barrows and like Carriages.
ALFRED ADAM BAYLISS, Madresfield, Beeches Road, West Bromwich, Stafford-
shire, 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:-
My invention relates to wheels, having rubber or composition tyres, for use
on trolleys, barrows and like carriages. In such rubber tyred wheels, it is an

page_text: advantage to have the body of the wheels split, in order to facilitate the fixing,
and removing of tyres, and my invention is a split wheel.
In the drawing Fig. 1, shews a four inch wheel, full size in elevation. Fig. 2,
the same wheel, in half section plan. Fig. 3, and Fig. 4, the key plates as used
at D D.
In each view A is the tyre, B and C the two main parts of the wheel body,
D D two locking plates or keys, E E F F segments of an interrupted screw
similar to those in the breech block of a gun, G₁ G₁ are the key plates, D¹ D¹¹,
bent over to secure them in place.
The use of the wheel is as follows:-The tyre A, is first put on over B, fitting
up against the flange of B. The projecting boss of C, is then inserted through
the hole in the centre of B, until the screw segments, E EF F, are in their pro-
per position for engaging; the wheel parts are then turned in directions opposite
to each other, with the result that the wheel is locked, with the tyre on it, in the
position shewn on the drawing. The locking keys or plates D D", are then
inserted, in the spaces left between the screw segments, E E F F and the said
locking keys or plates, are driven through the holes provided in C, and then
bent over as at G G, thus securing the wheel against unlocking when in use.
To remove the tyre the above operation is reversed.
To suit wheels of various diameters, the pitch of the screw segments may be
varied, also their number may be increased, or decreased, to any suitable number
of threads or segments. The key plates may also vary in number and shape.
The tyres may also be made of any suitable size and shape.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the said is to be performed, I declare that what
I claim is
(1). The improved split trolley wheel, consisting of two main parts, inter-
locked by means of the screw segments, as described, and securing the rubber or
composition tyre as shewn, the whole being finally locked, by means of the key
plate substantially as set forth.
(2). The improved keyplate, for use with the wheel, substantially as herein-
before described.
(3). The combination of the screw segments, and the key plates as shewn, and
herein before described substantially as set forth.
