Improvements in or connected with Furniture Casters and like
Articles.
I, JAMES PERCY ERNEST PROUD, of Fortal, Killiney, in the County of
Dublin, Ireland, Gentleman, do hereby declare the nature of this invention to be
as follows:-
This invention relates to improvements in furniture casters and other articles in
which a spindle or its equivalent revolves in a casing or sleeve and consists in
means for connecting the two parts together.
Hitherto this has generally been effected by forming a groove around the spindle
or inner cylinder and passing a screw through the outer casing or socket, the end
of the screw passing into the groove; or the parts have been connected by a
central rivet or bolt.
According to my invention I form the spindle or its equivalent with a projection
or projections adapted to work under a rim or flange or in a groove formed on or
in the socket or outer casing. A slot or slots may also be formed from the top of
the socket through the rim or into the groove to allow of the parts being put
together and separated from one another when required; or the outer casing may
be arranged to work between flanges on the upper and lower ends of the inner
casing.

Improvements in or connected with Furniture Casters and like
Articles.
I, JAMES PERCY ERNEST PROUD, of Fortal, Killiney, in the County of
Dublin, Ireland, Gentleman, 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:-

page_text: which a spindle or its equivalent revolves in a casing or sleeve and consists in
means for connecting the two parts together.
Hitherto this has generally been effected by forming a groove around the spindle
or inner cylinder and passing a screw through the outer casing or socket, the end
of the screw passing into the -groove; or the parts have been connected by a
central rivet or bolt.
According to my invention I form-the spindle or its equivalent with a projection
or projections adapted to work under a rim oriflange or in a groove formed on or
in the socket or outer casing. A slot or slots may also be formed from the top of
the socket through the rim or into the groove to allow of the parts being put
together and separated from one another when required; or the outer casing may
be arranged to work between flanges on the upper and lower ends of the inner
casing.
To enable my invention to be fully understood I will describe the same by
reference to the accompanying drawing, in which various forms of furniture casters
are shewn in vertical section in illustration of my invention.
Similar letters of reference indicate similar or corresponding parts in the several
figures.
a is the socket or outer casing, b the spindle or inner cylinder, which revolves on
bearing surfaces at the top and bottom of the socket or outer casing as shewn.
In Figures 1, 2, 3 and 4 the said inner cylinder b is provided with a projection
or projections adapted to work in a groove c formed in the outer casing a.
In Figure 1 the projection has the form of a pin cast with the inner cylinder b,
the upper end e of the outer casing a being provided with a slot at c¹ to allow of
the passage of the pin when introducing the inner into the outer one.
In Figure 2 the projections d are formed after the inner cylinder has been
inserted in the outer casing or socket a by forcing small tongues of the inner casing
outwards.
In Figure 3 the projections & form a continuous flange around the inner casing b,
the inner casing being first inserted into the outer casing and the upper part e of
the latter being then forced into position by steam or hydraulic pressure.
In Figure 4 the projection is formed by a screw which is screwed through the
inner casing into the wood of the leg of the chair or the like from the outside,
the head of the screw forming the projection. The inner casing b is inserted in the
outer casing and the screw is then introduced through the opening f in the outer
casing a.
In Figure 5 the inner casing 'b'is provided with a somewhat lengthened flange d
with a groove g above the same. The outer casing a has no groove formed in it
and the flanged forms the upper bearing surface of the inner casing. The inner
casing is first introduced into the outer casing and the top edge of the latter is
then spun or rolled over the upper edge of the flange d.
Figures 6 and 7 illustrate two formis of the modification of my invention in
which the inner cylinder is connected to the outer casing or socket by means of
flanges on the upper and lower ends of the inner cylinder. In Figure 6 the upper
bearing surface between the two casings is curved and forms the upper flange, the
lower flange being formed by a pin h passing through the lower end h¹ of the inner
cylinder which penetrates the outer casing. In Figure 7 the upper flange is made
by enlarging the diameter of the inner cylinder above the top end of the outer
casing and the lower flange by forming a flange on or expanding the lower end of
the inner casing."
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is
1. The improved construction of furniture caster hereinbefore described and
illustrated respectively in Figures 1, 2, 3, 4 and 5.
2. In furniture castors of the kind described connecting the inner and outer

page_text: casings by flanges formed on the upper and lower ends of the inner casing, sub-
stantially as described.
3. The improved furniture casters hereinbefore described and illustrated in
Figures 6 and 7 of the drawing.
