Improvements in Furniture Castors.
We, JOSEPH CROWTHIER, of 1, Queen's Grove, North Road, Longsight, Man-
chester, in the County of Lancaster, Mechanic, and WILLIAM DOLLIN, of 52,
Sidney Street, Oxford Road, Manchester aforesaid, Joiner and Builder, do
hereby declare the nature of this invention to be as follows:----
Our invention relates to improvements in furniture castors and the chief object
of our invention is to reduce friction so that the roller of the castor will swivel·
more freely than is the case with castors of the ordinary construction; further
to save labour in the manufacture, and to secure the castors to furniture in
less time.
To effect our objects we form with or secure to the frame in which the roller
is pivoted a stud or spindle the upper end of which is coned, or pointed. This
spindle is fitted into a flanged cup or socket which is bored to receive it and
coned at the end of the hole to form a bearing surface for the upper end of the
spindle. In order to connect the spindle to the socket we form a recess in the
socket round the bottom of the hole, and in this recess we fit a small ring of metal.
cut across in one place to form a spring clip, so that the spindle when pressed
into the socket, which can be done after the socket has been secured to the
furniture, is clipped by the spring ring and held firm enough to withstand all
ordinary use.
As an alternative construction the socket might be reversed; to effect this
we should secure in any convenient manner to the leg of the piece of furniture
a plate, say provided with an open cup if desired, and to the centre and lower
side of this plate we cast or secure a spindle with a coned or pointed end, and
we form with the frame which carries the roller a boss which is drilled out to
receive the spindle and coned at its bottom to receive and form a bearing for the
spindle point, and we form a recess near the mouth of the hole to receive a split
ring to connect the frame to the spindle as before mentioned.
The roller and the spindle can be removed from the socket at any time by
exerting sufficient pressure to overcome the grip of the split ring upon the
spindle.

Improvements in Furniture Castors.

be performed, to be particularly described and ascertained in and by the follow-
ing statement:
-
Our invention relates to improvements in furniture castors and the chief
object of our invention is to reduce friction so that the roller of the castor will
swivel more freely than is the case with castors of the ordinary construction;
further, to save labour in the manufacture and to secure the castors to furniture
in less time.
And in order that our invention may be fully understood and readily carried
into effect we will describe the accompanying sheet of drawings reference being
had to the figures and letters marked thereon.
Figure 1 is an elevation, partly in section, of a furniture castor made according
to our improvements.

Figure 2 is a similar view to Figure 1 showing the castor socket formed with
a cup for convenience in securing it to the leg of a chair or, the like.
Figure 3 is a sectional elevation illustrating an alternative construction in
which the socket and stud or spindle are reversed.
Figure 1 is a detail view of a split ring which we employ to form a spring clip.
In Figure 1, a designates the roller of the castor: 6 the frame in, which
the roller is pivoted; the stud or spindle which we form with or secure to
the frame 6; the upper end of this spindle is coned or pointed and fitted into a
flanged cup or socket d which is bored to receive it. In order to connect the
spindle to the socket we form an annular recess in the socket near the
bottom of the hole and in this recess we fit and spring in a small ring of metal e,
see Fig. 1, cut across in one place to form a spring clip so that the spindle c
when pressed into the socket d, which can be done after the socket has been
secured to the furniture, is clipped by the spring ring and held firm enough to
withstand all ordinary use.
In Figure 2, The construction is similar to that already described with
reference to Figure 1 except that the foot of the socket d is made with a cap f
for convenience in securing the socket to the leg of a chair or the like.
In the alternative construction illustrated by Figure 3, the spindle is
formed with or secured to an open cap f which is secured to the leg of the piece
of furniture and the socket d is formed with the frame b of the roller the con-
struction in other respects being similar to those already described.
It will be obvious from the foregoing description and from the drawings that
in each construction illustrated all the weight of the furniture is supported on
the coned end of the spindle bearing against the correspondingly formed end of
the socket and as the spindle is only gripped by the spring ring e which is fitted
loosely in its annular recess the spindle can swivel freely with its frame and
pivoted roller.
The castor can be withdrawn from the piece of furniture at any time by exert-
ing sufficient force to overcome the grip of the split ring e upon the spindle c.
Instead of the split ring e we might employ a screw projecting into an
annular groove in the spindle or any equivalent device for retaining the spindle
in the socket.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is:-
1. In a furniture castor, the combination with a stud or spindle having a coned
end and formed with or secured to the roller frame, of a socket formed to receive
the cone ended spindle and adapted to be secured to a piece of furniture and
means, such as a split ring, for retaining the spindle in the socket, substantially
as herein set forth.
2. In a furniture castor, the combination with a stud or spindle having a

piece of furniture, of a socket formed to receive the cone ended spindle and
formed with or secured to the roller frame and means, such as a split ring fitted
in an annular recess in the socket, for connecting the two parts together, sub-
stantially as herein set forth.
3. The several constructions and combinations of parts substantially as herein
described and as shown on the accompanying drawings.
