Certain Improvements in Furniture Castors and the like.
I, HENRY MOORE, of 87, Clifford Street, Lozells, Birmingham, in the County
of Warwick, Brass and Iron Founder, do hereby declare the nature of this inven-
tion to be as follows:-
This invention has reference to that kind of furniture castors and other like
castors such as for pianofortes and organs in which castors a horn piece turning
upon a central vertical axis carries the castor bowl or roller to run along the floor
and the upper part of the horn piece carrying a friction wheel the axis of which
is arranged about centrally above the bowl and has its axis at about right
angles to the axis of the bowl the said friction wheel being arranged to bear
against the underside of the castor plate or socket so as to take the bending
strain off the vertical pin and thus make the horn piece turn more freely with
the bowl, and this invention consists of the herein described improvements in
the construction of the friction wheel and axle and their arrangement with the
horn piece and also the bearing surface on the castor plate or socket whereby
the manufacture of the parts is facilitated and they are caused to last longer in
wear.
In carrying out this invention I make the friction wheel in a piece with its
axle preferably as a steel stamping the said axle projecting at both sides of the
friction wheel and turning in slots in the top of the horn piece above the top
of which the friction roller projects. I provide a projecting annular rim all
round the bottom of the castor plate or socket and flush with the bottom of the
same to form a race for the friction wheel. As the friction wheel axle is made
in a piece with the wheel itself and takes and turns in a bearing in the horn
piece on each side of the friction wheel, the friction wheel is much stronger and
is much better supported than is the case in other castors of this kind where the
friction wheel is pierced with a hole and turns on a stationary axis fixed to the
horn piece.

and ascertained in and by the following statement:-
This invention has reference to that kind of furniture castors and other like
castors such as for pianofortes and organs in which castors a horn piece turning
upon a central vertical axis carries the castor bowl or roller to run along the floor
and the upper part of the horn piece carrying a friction wheel the axis of which
is arranged about centrally above the bowl and has its axis at about right
angles to the axis of the bowl the said friction wheel being arranged to bear
against the underside of the castor plate or socket so as to take the bending
strain off the vertical pin and thus make the horn piece turn more freely with
the bowl, and this invention consists of the herein described improvements in
the construction of the friction wheel and axle and their arrangement with the
horn piece and also the bearing surface on the castor plate or socket whereby
the manufacture of the parts is facilitated and they are caused to last longer in
wear.
I will describe my invention by referring to the accompanying drawings on
which Fig. 1 is a front elevation and Fig. 2 is a side sectional elevation of a fur-
niture castor constructed according to this invention; Fig. 3 shews the horn-
piece of the castor separately; Fig. 4 shews the frictional wheel and its axle
separately; Fig. 5 is an inverted view of the castor plate of the said castor on
line XX of Fig. 2; Fig. 6 is a side elevation and Fig. 7 is a front elevation of a
bedstead castor with my invention applied shewing also in Fig. 6 the foot of
the bedstead leg to which the castor is secured and Fig. 8 shews separately the
horn-piece of the castor illustrated by Figs. 6 and 7.
The same letters of reference indicate the same or corresponding parts in all
the figures.
A is the horn piece of the castor which turns on the central vertical axis B and
carries the castor bowl or roller C revolving on the cross pin I) secured in the
horn-piece A; E is the friction wheel which in carrying out this invention I
make in a piece with its axle el preferably as a steel stamping said axle el pro-
jecting at both sides of the friction wheel E and turning in slots a¹ a² which I
form in the top of the horn-piece A above the top of which the friction wheel E
projects so as to bear against the bottom of the castor plate or socket or foot of
the bedstead leg to which the castor is attached. As the friction wheel axle c¹
is made in a piece with the wheel E itself and turns in the bearings a¹² in the
horn-piece A at each side of the friction wheel E, the latter is much stronger and
much better supported than is the case in castors of this kind as usually made and
in which the friction wheel is made with a hole and turns on a stationary pin
or axis fixed to an upwardly projecting ear of the horn-piece.
In combination with the castor having its friction wheel E and bearings
constructed as above described, I provide a projecting annular rim f¹ all round
the bottom of the castor plate F, or round the castor socket, flush with the bottom
of the same outside the screw holes f³ thus forming a circular race for the friction
wheel E to bear against.
When my invention is applied to those castors which are used for metallic
bedsteads and which are sold separately from the vertical pin or axis on which
the horn-piece turns such castors as shewn for instance by Figs. 6, 7 and 8, the
combined friction wheel E and its axle e¹ would be liable to fall out of the bear-
ings a¹ a² unless some special means such as shewn for instance by Figs. 6, 7
and 8 were provided to keep the combined friction wheel E and its axle e¹ in
place. For this purpose the horn-piece A may have two projecting wires a³ at
cast in it as shewn in Fig. 8 which after the friction roller E has been placed in
position with its axle e¹ in the slots a¹ a³ these wires a³ a are bent down, as
shewn in Figs. 6 and 7, over the slots a¹ a² so as to prevent the roller E from
falling out of the horn-piece A. It is to be understood however, that I make no
claim to these wires a³ a as part of my invention.

page_text: Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed, I declare that what I
claim is:-
1. In a furniture castor or other like castor of the kind herein referred to,
the combination of the horn-piece A made with the top slots a¹ a² and the friction
wheel E made with its axle el projecting at each side thereof and turning in the
slots a a of the horn-piece, for the purpose and substantially as set forth.
2. In a furniture castor or other like castor of the kind herein referred to, the
combination of the horn-piece A made with the top slots a¹ a², the friction
wheel E made with its axle el projecting at each side thereof and turning in the
slots a as of the horn-piece, the roller C carried by a cross pin D of the horn-
piece, the central pin on which the horn-piece turns and the castor plate or
castor socket fixed to the central pin and made with a race for the friction wheel,
substantially as set forth and illustrated.
