RICHARD HAMBLY HUGHES 307 and 309 Mare Street Hackney in the county of
Middlesex, Furrier do hereby declare the nature of this invention to be as follows :-
-
My present invention has for its object an improved method of connecting the base
of a castor to the socket or cap into which the leg or legs of a chair fit.
Castors have hitherto been inade with the socket or cap and the wheel or rollers so
fitted together as to form one complete article this in practice is the source of much
loss and inconvenience owing to the roller part being usually worn out or broken
while the top remains sound & good, to obviate this disadvantage I make the castor in
two or more parts, the socket or cap (which may be of any shape such as a squaro
socket to suit a square leg of table, or round to suit a round leg or it may be of plate
form to screw up against the end of a leg) at its lower end being screwed with a standard
size female thread and the lower or roller part being furnished with a male thread of
a standard size as to fit the female thread accurately or I can reverse the position of
the threads, making the male thread on the lower part and the female thread on the upper
part of the castor but; I prefer the former principle, these two parts where screwed
together I designate the main screw.
I also fit one or more set screws or pins to either the male or female thread which
ever I may find to be most convenient which screw or pin can be tightened up after
the castor is in position, & so prevent any possibility of the main screw coming
undone; this arrangement is applicable to any form of castor but I prefer to employ
it in conjunction with my ball bearing castor as described & set forth in my Patent
No. 3753 of the present year.

RICHARD HAMBLY HUGHES 307 and 309 Marc Street Hackney in the County of
Middlesex Furrier 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 present Invention has for its object an improved method of connecting the base
of a caster to the socket or cap into which the leg or legs of a chair fit. Casters have
hitherto been made with socket or cap and the wheel or roller so fitted together as to
form one complete article, this in practise is the source of much loss and inconvenience
owing to the roller part being usually worn out or broken while the top remains sound
and good; to obviate this disadvantage I make the caster in two or more parts, the
socket or cap (which may be of any shape, such as a square socket to suit a square
leg of table, or round to suit a round leg, or it may be of plate form to screw up
against the end of a leg) at its lower end being screwed with a standard size female
thread and the lower or roller part being furnished with a male thread of a standard
size so as to fit the female thread accurately, or I can reverse the position of the
threads, making the female thread in the lower part and the male thread on the upper
part of the Caster but I prefer the former principle, these two parts I designate the
main screw.
I also fit one or more set screws or pins to either the male or female thread
whichever I may find to be most convenient which screws or pins can be tightened up
after the Caster is in position and so prevent the main screw from coming undone this
arrangement is applicable to any form of Caster but I prefer to employ it in
conjunction with my Ball bearing Caster described and set forth in my Patent
No. 3753 of the year 1886.
In the Drawings Fig. I shows the socket or cap A, and B is the male screw.
Fig. II shows the roller part of the Caster, B1 is the female screw, C is the casing in
which the female screw thread is made, and D is the ball or roller of the
Caster, E, E, E, are the set screws or pins. Figs. 3 and 4 are plans of Figs. 1 and 2.
Fig. 5 is a complete Caster.
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
In a Caster making the socket or cap separate from the lower or roller part and so
arranged that the two parts screw together, with the pins or set screws for preventing
the main screw from coming undone substantially as set forth.
