I SAMUEL TIMINGS 23 Great Hampton Street Birmingham in the County of
Warwick Manufacturer do hereby declare the nature of my invention for IMPROVE-
MENTS IN CASTORS SUITABLE FOR USE ON CHAIRS, SOFAS BEDSTEADS AND OTHER.
ARTICLES to be as follows:―
This invention consists in making a castor in such a manner that when several
are fixed to the legs of Tables; Chairs; Sofas Bedsteads or other articles, they will
quickly rotate on the centre spindle to bring all the bowls to roll in the direction
that a sofa or other article is being moved; there are other advantages resulting
from my method of making the castors as hereinafter set forth.
I provide a centre spindle which will by preference be formed into a screw at one
end for screwing into the wood leg of furniture or other article.
•
Near the root of this screwed part I by preference form the spindle square, beyond
this square part I make the spindle round.
On the square part of spindle I in some cases fix a circular disc, in other cases
I fix a cup or socket whose bottom forms a circular disc.
I provide an axle plate which would by preference be a flat piece of mettal cut
to form three, four, or any suitable number of arms The end of each arm would
be formed into a circular projection or axle the axle-plate would be pierced with a
central hole corresponding with the round part of spindle.
.
I provide, three, four or any suitable number of wheels or disc rollers, and pass
one on to each of the circular projecting axles of the axle plate, I then secure the
disc rollers in possition by riveting the ends of axles or by other suitable mechanical
means.
I provide a horn to carry the bowl, the top part of the horn would be made flat
and of sufficient dimentions to form a bearing for the disc-rollers.
Two ears or sides would extend downwards from the top of horn, one on the.
right side and one on the left side, these ears would be curved inwards so as to
leave a space between the two sufficiently narrow to receive the bowl edgeways.
I take the spindle with the circular disc, cup or socket secured to the square part
as hereinbefore mentioned I next take a washer whose thickness is about equal to

page_text: the cord of arch of wheel projecting above axle plate I pass this washer over the
circular end of spindle and let it rest on the circular disc or bottom of cup: I next
take the axle plate (with the disc rollers on the axles) and pass the central hole
over circular end of spindle the axle plate would bear against the washers and
the periphery of the disc rollers would bear against the bottom of cup or socket.
I next take the horn and pass the central hole in flat top part over the circular
end of spindle until this flat part took a bearing on that periphical edge of disc
wheels, opposite to the edge bearing against the bottom of socket. The circular
end of spindle that projects through the flat top, could be secured in position by
riveting or other suitable mechanical means.
In using four of my improved castors on the legs of a sofa it would be obvious
that the weight of sofa and ocupants acts directly and vertically on the periphery
of the disc rollers against the bottom of socket and against the flat top of the horn
. The frictional contact being tangentical is consequently very slight.
.
The horn rotating on the spindle answering so readily to the slightest amount of
side pressure I am enabled to keep the central working axis of my bow!, very
much nearer the centre of spindle than has hithertoo been found practicable, the
result being that castors made on my improved principal will not be so liable to
wrench off the legs of furniture from tortion pressure as castors now in use.
I can where desirable form bearings on the flat top of horn and hang the disc
rollers therein to work on the bottom of socket.

ARTICLES and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:
This invention consists in making a castor in such a manner that when several
are fixed to the legs of Tables; Chairs; Sofas Bedsteads or other articles, they will
quickly rotate on the centre spindle to bring all the bowls to roll in the direction
that a sofa or other article is being moved; there are other advantages resulting
from my method of making the castors, as hereinafter set forth.
I provide a centre spindle which will by preference be formed into a screw at one
end for screwing into the wood leg of furniture or other article.
Near the root of this screwed part I by preference form the spindle square,
beyond this square part I make the spindle round.
On the square part of spindle I in some cases fix a circular disc, in other cases>
I fix a cup or socket whose bottom forms a circular disc.
I provide an axle plate which would by preference be a flat piece of metal cut
to form three, four, or any suitable number of arms The end of each arm. would
be formed into a circular projection or axle the axle plate would be pierced with a
central hole corresponding with the round part of spindle.

I provide a horn to carry the bowl, the top part of the horn would be made flat

Two ears or sides would extend downwards from the top of horn, one on the
right side and one on the left side, these ears would be cut ved finwards so as to
leave a space between the two, sufficiently narrow to receive the bowl edgeways.
I take the spindle with the circular disc, cup, or socket secured to the square
part as herein before mentioned I next take a washer whose thickness is about
equal to the chord of that arch of wheel projecting above axle plate I pass this
washer over the circular end of spindle and let it rest on the circular, disc or
bottom of cup I next take the axle plate with the disc rollers on the axles and
pass the central hole over circular end of spindle the axle plate would bear against
the washers, and the periphery of the disc rollers would bear against the bottom of
cup or socket.

wheels opposite to the edge bearing against the bottom of socket. The circular end
of spindle that projects through the flat top, could be secured in position by riveting
or other suitable mechanical means.
In using four of my improved castors on the legs of a sofa it would be obvious
that the weight of sofa and ocupants acts directly and vertically on the periphery
of the disc rollers against the bottom of socket and against the flat top of the horn
The frictional contact being tangential is consequently very slight.
.
The horn rotating on the spindle answering so readily to the slightest amount of
side pressure I am enabled to keep the central working axis of my bowl, very much
nearer the centre of spindle than has hithertoo been found practicable, the result
being that castors made on my improved principal will not be so liable to wrench
off the legs of furniture from torsion pressure as castors now in use.
.
I can where desireable form bearings on the flat top of horn and hang the disc
rollers therein to work on the bottom of socket and on the flat top of horn The
rollers would thus be working on fixed axles instead of on rotating axles.
I will now proceed to describe with reference to the accompanying drawings the
manner in which my invention is constructed and used.

I have represented the thre ordinary fixtures 'generally used in the construction
of castors viz the plate B; the narrow rim or socket C and the deep cup shaped
socket D I can where desireable make the centre spindle A with a screwed end
when connected to the plate B or the cup shaped socket D but I prefer to use a

page_text: dowl as shown at O Figure 6 and a riveted fastening as represented at P Figure 4
In order to prevent the hole M in flat top part of horn wearing loose on the round
part of spindle A, I provide a steel bush as represented at N Figures 11 and 18;
this bush would be fixed in the flat top in the manner indicated at Figures 11
and 18.
On refering to Figure 5 it will be observed that the centre line W X passing
through the centre of spindle A is close to the centre line Y Z passing through the
central axis of bowl this close proximity of the central axis of bowl with the centre
of spindle, secures the castor against excessive torsion pressure when in use as
herein before explained.
Instead of using a loose washer to rest on the circular disc or bottom of cup
socket I can form the spindle A with a flange on it as represented at R Figures 1,
2, 3, 4, 5, 6, 11.
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 combination of a spindle; a disc, cup or socket; an axle plate on which
is formed arms or axles; two, three, four, or any suitable number of wheels or disc
rollers; a horn and a bowl
The bowl revolving in the horn, the flat top part of the horn revolving on the
spindle, the axle plate revolving on the spindle, the disc wheels revolving on the
arms or axles of axle plate, the periphery of the wheels or disc-rollers rolling on
the flat top part of the horn and on the under side of disc cup or socket,' as
illustrated and described the whole forming a castor suitable for use on the legs of
furniture and for other like purposes.
