Metallic Bedstead Chill Fitter do hereby declare the nature of this Invention to be as
follows:
In casters for furniture as ordinarily made the horn carrying the bowl and turning
upon the pin or axis of the caster is inseparable from the cup or plate of the
castor.
Various inconveniences attend the use of casters of this the ordinary construction.
For example in the transit of inetallic bedsteads and other articles of furniture having
casters the horns and bowls of the casters are liable to injury by the rough treatment
the articles are exposed to. When the parts of metallic bedsteads are being put
together or separated the pillars cannot safely be put to stand upright against a wall
in consequence of the facility with, which the bowls of the castors turn. Further if
the rivetting by which the horn is connected to the pin is done carelessly the horn is
made incapable of turning on the pin or turns thereon with difficulty.
The object of my invention is to remedy these and like inconveniences and my said
invention consists in fixing the horn to the axis of the caster and making the said
axis take into and rotate in a cylindrical hole in the bowl or plate of the caster or in
the leg of the table or foot of the pillar of the bedstead or the like. Or when the pin
is fixed I connect the horn in the manner hereinafter described.
I will describe may invention in connection with a caster of one of the pillars of
a metallic bedstead. Instead of making the horn of the caster turn upon the cylin-
drical pin or axis of the caster I fix the said pin or axis to the horn so that the horn
and pin move together. In the foot of the pillar I make a vertical cylindrical hole of
such a size that the pin of the caster when inserted therein will turn freely but work
closely therein. In order to retain the pin of the caster in the hole in the foot. I make
a shallow depression or neck near the upper end of the pin and in the said neck I fit
a steel spring of the figure of a short piece of open jointed tubing. This spring is
retained in position by the shoulders at either end of the said neck and when in its
normal or expanded state it is of slightly larger diameter than the hole in which the
nin works.

page_text: When the pin is inserted in the hole in the foot of the bedstead and pushed home
therein the said spring is compressed and brought into a state of tension. By its
elasticity there is produced sufficient friction to retain the pin in the hole when
however it is wished to detach the horn and bowl it is only necessary to pull the horn
downwards with a force which one hand will easily exert when the pin will be drawn
out of the hole in the foot. Thus the horn and bowl can readily be attached to and
detached from the foot of the pillar by simply pressing home the pin in the hole or
withdrawing it therefrom.
In case of a socket or plate caster the pin of the caster works in a tube in the axis of
the socket or plate or in the case of the leg of a table or other article of furniture
made of wood the pin may work in a hole in the leg but I prefer that in all cases the
pin should work in a tube or hole made in metal.
Where for any reason it is preferred to make the pin fixed I make the horn
detachable from the pin in the following manner. I make a neck or depression near
the end of the pin and on the underside of the horn I fix at opposite sides of the hole
in the horn light spring arms the ends of which are turned inwards. When the horn
is pushed home on the pin the ends of the said spring arms snap into the neck or
depression in the pin and prevent the horn from passing off the pin. In order to
remove the horn the spring arms require to be lifted from the depression or neck in
the pin when the horn can pass from off the pin.

page_text: I JOHN GARVEY of No. 17 Florence Road, Handsworth in the County of Stafford
Metallic Bedstead Chill Fitter do hereby declare the nature of my invention and
in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement:-
In casters for furniture as ordinarily made the horn carrying the bowl and
turning upon the pin or axis of the caster is inseparable from the cup or plate of the
caster.
Various inconveniences attend the use of casters of this the ordinary construction.
For example, in the transit of metallic bedsteads and other articles of furniture having
casters the horns and bowls of the casters are liable to injury by the rough treatment
the articles are exposed to. When the parts of metallic bedsteads are being put
together or separated the pillars cannot safely be put to stand upright against a wall
in consequence of the facility with which the bowls of the casters turn. Further if
the rivetting by which the horn is connected to the pin is done carelessly the horn is
nade incapable of turning on the pin or turns thereon with difficulty.
The object of my invention is to remedy these and like inconveniences and my said
invention consists in fixing the horn to the axis of the caster and making the said axis
take into and rotate in a cylindrical hole in the bowl or plate of the caster, or in the
leg of the table or foot of the pillar of the bedstead or the like. Or when the pin is
fixed I connect the horn in the manner hereinafter described.
I will describe my invention in connection with a caster of one of the pillars of a
metallic bedstead. Instead of making the horn of the caster turn upon the cylin-
drical pin or axis of the caster I fix the said pin or axis to the horn so that the horn
and pin move together. In the foot of the pillar I make a vertical cylindrical hole of
such a size that the pin of the caster when inserted therein will turn freely but work
closely therein. In order to retain the pin of the caster in the hole in the foot I make
a shallow depression or neck near the upper end of the pin and in the said neck I fit
a steel spring of the figure of a short piece of open jointed tubing. This spring is
retained in position by the shoulders at either end of the said neck and when in its
normal or expanded state it is of slightly larger diameter than the hole in which the
pin works.
When the pin is inserted in the hole in the foot of the bedstead and pushed_home
therein the said spring is compressed and brought into a state of tension. By its
elasticity there is produced sufficient friction to retain the pin in the hole; when
however it is wished to detach the horn and bowl it is only necessary to pull the horn
downwards with a force which one hand will easily exert when the pin will be drawn
out of the hole in the foot. Thus, the horn and bowl can readily be attached to and

page_text: detached from the foot of the pillar by simply pressing home the pin in the hole or
withdrawing it therefrom.
Where for any reason it is preferred to make the pin fixed I make the horn
detachable from the pin in the following manner. I make a neck or depression near
the end of the pin and on the underside of the horn I fix at opposite sides of the hole
in the horn, light spring arms the ends of which are turned inwards. When the horn
is pushed home on the pin the ends of the said spring arms snap into the neck or
depression in the pin and prevent the horn from passing off the pin. In order to
remove the horn the spring arms require to be lifted from the depression or neck in
the pin when the horn can pass from off the pin.
I will now proceed to describe with reference to the accompanying Drawing the
manner in which my invention is to be performed.
Figure 1 represents partly in elevation and partly in vertical section a caster made
and connected to the foot of the pillar of a bedstead according to the first part of my
invention; Figure 2 represents the caster detached and Figure 3 represents in
elevation partly in section and plan of underside the foot of the bedstead pillar with
the caster removed.
The same letters of reference indicate the same parts in Figures 1, 2 and 3.
a is the horn of the caster; b the bowl and e the pin or axis, the said pin or axis
being rivetted to the said horn so that the horn and pin move together; d is the
shallow depression or neck near the upper end of the said pin c
In this depression
or neck a steel open jointed tubular spring e is fitted the said spring being retained in
its place by the shoulders at either end of the said neck. The open joint of the tubular
spring e permits of the expansion and contraction of the said spring for increasing or
diminishing its diameter. In the foot of the bedstead pillar is a vertical cylindrical
hole g lined by preference by a tube upon which the foot is cast. Into this holo g
the pin c of the caster may be fitted and turn therein. When the spring e on the
pin c is in its normal or expanded state it is of slightly larger diameter than the hole g
for receiving the said pin.
In order to secure the caster to the pillar of the bedstead, the pin to which the
horn is fixed is inserted and pushed home in the hole g in the foot of the pillar. The
springe on the said pin is thereby compressed and brought into a state of tension as
illustrated in Figure 1, the elasticity of the said spring producing sufficient friction to
retain the pin c in the hole g but permitting the said pin to rotate in the said hole
when required. To detach the caster from the pillar it is only necessary to pull the
born downwards with a force sufficient to overcome the resistance of the compressed
spring e when the pin c may be drawn out of the hole, the spring resuming its normal
or expanded state as represented in Figure 2.
In case of a socket or plate caster the pin e of the caster works in a tube in the axis
of the socket or plate; or in the case of the leg of a table or other article of furniture
the pine may work in a hole in the leg but I prefer that in all cases the pin should
work in a tube or hole made in metal.

the underside of the socket ² of the horn and on opposite sides, are light spring
arms k, k the ends of which are turned inwards. On pushing home the socket a² of
the horn on the fixed pin h the ends of the spring arms k, kare made to snap into
the neck or depression i, in the pin and prevent the horn froin passing off the said
pin as represented in Figures 4 and 5.
To remove the horn the spring arms k, kare separated and thereby lifted or raised
from the depression or neck i, in the pin h when the horn can be removed from the
said pin as illustrated in Figures 6 and 7.

page_text: In a socket or plate caster the pin hi is fixed to the socket or plate of the caster.
Having now particularly described and ascertained the nature of my invention and
the manner in which the same is to be performed I declare that I claim as my
invention of "Improvements in casters for furniture."
First. The construction and arrangement of parts herein before described and
illustrated in Figures 1, 2 and 3 of the accompanying Drawing for attaching the horn
and bowl of the caster to and detaching them from the socket or plate of the caster,
the foot of the pillar, leg of the table or other part of the article of furniture; that is
to say, fixing the horn of the caster upon the pin or axis and forming in the socket or
plate of the caster, or in the pillar or leg or other part of the furniture, a vertical
cylindrical hole for receiving the caster pin or axis and retaining the said pin or
axis in the said hole by means of an open jointed tubular spring or other equivalent
spring substantially as described and illustrated.
Secondly. The construction and arrangement of parts herein before described and
illustrated in Figures 4. 5. 6 and 7 of the accompanying Drawing for attaching the
horn and bowl of the caster to and detaching them from the pin or axis of the caster;
that is to say, making the pin of the caster fixed and providing it with a neck
or depression and combining with the socket of the caster horn, spring arms for
snapping into the neck or depression in the pin and retaining the horn on the said pin
substantially as described and illustrated.
