Improvements in the Connection of Castors to Bedsteads and Cots
and such like.
We, FREDERICK CHARLES RANDALL, Foreman, of 374, Rotten Park Road, in
the City of Birmingham, and WALTER THOMPSON, of 420, Rotten Park Road,
as aforesaid, Brass Bedstead Maker, do hereby declare the nature of this
invention to be as follows;
-
The improvements according to this invention relate to detachable castors, and
consist in a simple means whereby they are more effectively connected to bed-
steads cots and such like in a neat and inexpensive manner.
According to this invention a peg or pin, having a rounded outer end formed
with an annular groove, neck, or undercut-part slightly inwards of it, is cast
into the foot of the pillar or post of the bedstead, and within the yoke or
cross bar of the castor bracket is formed a vertical hole or opening with a resilient
inner edge, the said edge constituting spring jaws. The peg or pin, as afore-
said, passes through the said hole in attaching the castor, and the resilient edge
has a snap action into the annular groove or neck of the peg so as to hold the
said castor onto the said peg until force is used to open out the resilient edge
sufficient to detach the castor.
The resilient edge is preferably, according to this invention, formed by the
split inner end of a thin metal sleeve or ferrule which fits a hole in the yoke
of the castor bracket so that its inner end projects somewhat and constitutes spring
jaws, the said sleeve or ferrule being fixed to the yoke by portions displaced
from its inner edge, in forming the spring jaws, being turned over on the under-
side of the yoke, the other end of the said sleeve having a small flange or
collar upon it which abuts against the top face of the yoke. A thin metal socket
with indented portions in its walls near its bottom may take the place of the
sleeve or ferrule and be attached to the yoke, and both it and the ferrule can be
made from the blank.
The principle feature of this invention is the carrying of the spring jaws on the
yoke of the castor and the peg on the foot of the bedstead pillar or post, as thereby
the work of fitting the parts, especially the casting in of the peg, is
simplified.

and such like.
We, FREDERICK CHARLES RANDALL, Foreman, of 374, Rotton Park Road, in
the City of Birmingham, and WALTER THOMPSON, of 420, Rotton Park Road,
as aforesaid, Brass Bedstead Maker, do hereby declare the nature of this inven-
tion and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
The invention relates to the connection of castors to bedsteads cots and such
like, and consists of the hereinafter described improvements in what are known
as detachable castors by which such castors are more effectively connected to the
pillars or posts of bedsteads and cots, and this in a neat and inexpensive manner.
According to this invention a peg or pin having a rounded outer end and an
annular groove or neck inwards of the said end is cast into or otherwise fixed to the
foot of the pillar or post of a bedstead, and within the yoke or cross-bar of the
castor-bracket is formed a hole or opening with a resilient inner or lower edge,
the said edge constituting spring jaws. The peg or pin, as aforesaid, passes
through the vertical hole or opening in attaching the castor to a pillar or post,
and the resilient edge has a snap action over the rounded end of the peg or pin
into the groove or neck inwards of it, the engagement of the spring jaws at the
back of the rounded end being such as to require considerable pulling off force to
open out the resilient edge sufficient to detach the castor from the peg or pin.
The improvements according to this invention are practically illustrated in
the accompanying sheet of drawings, Fig. 1 showing a castor connected according
to this invention to the lower end of a metallic bedstead pillar or post. Fig. 2
shows the castor, Fig. 1, detached from the pillar or post, and Fig. 3 is an
underside plan of the castor Fig. 2, showing in particular the resilient edge before
referred to on the cross-bar or yoke of the castor-bracket. Fig. 4 is a top side
plan of the castor Fig. 2. In the said drawings a peg or pin a³, having a rounded
end a formed with an annular groove, neck or undercut part a slightly inwards
of it, is rigidly cast into the foot a of the pillar or post a of a bedstead vertical or
in line with the said post, and within the yoke or cross-bar c³ of the castor-bracket c
is formed a vertical hole or opening having a resilient inner edge d, the said
vertical hole being of a size to fit the peg or pin a³, and the said resilient edge
constituting spring jaws. The peg or pin a² when the castor e is being attached
to the pillar or post, a, passes through the hole or opening in the castor
bracket, and the resilient edge d has a snap action over the rounded end a³ of the
said peg to engage the groove, neck or undercut part at the back of the said end,
the said engagement holding the castor onto the peg until sufficient pulling off
force is used to open out the resilient edge sufficient to allow of the passage of the
end a³.
The resilient edge d is according to this invention formed by splitting the end
of a thin metal sleeve or ferrule, g, which fits the hole in the yoke of the
castor-bracket, and arranging the said sleeve within the said hole so that the said
split end projects somewhat from the inner face or underface of the said yoke.
The sleeve or ferrule is fixed in the hole of the yoke by rolling over the top
edge on the one side of the yoke, forming it into a collar or a flange, and by
displacing portions of the said sleeve upon the lower edge to be turned over
against the underside face of the yoke. This is clearly shown from the drawings
by Figs. 2, 3 and 4.
The sleeve or ferrule is preferably made from a small flat metal blank.
The

page_text: principal feature of the improvements according to this invention is the arrange-
ment of the spring jaws or resilient edge on the castor bracket and the peg on the
foot of the bedstead pillar or post, as thereby the work of fitting the parts is very
much simplified and the casting in of the peg in the case of metallic bedsteads
rendered easy.
In applying the invention to wooden bedsteads or other articles of furniture
other than metallic to which castors are applied, the peg or pin a² may be rivetted
to a socket or a plate which is in turn wood-screwed or otherwise fixed to a part
such as a leg, or a piece of the frame, of the article.
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 :-
First. In detachably connecting castors to bedsteads cots and such like to which
castors are applied, the combination of a peg or pin such as a fixed upon the
pillar or post or frame, the said peg or pin having a rounded end a with a
groove, undercut, or equivalent part a inwards of it, and a castor whose yoke
cross-bar is formed with a hole having a resilient inner edge to fit over and
engage the said peg or pin in the manner substantially as described.
ог
Second. In castors, bedsteads, and other articles to which castors are applied,
the combination of a peg or pin 2 upon the pillar, post, or frame, and which has
a rounded end a³ and a part such as a inwards of said end a castor having a hole
within it, and a sleeve or ferrule g fitting in the said hole and being formed
with a resilient edge or with spring jaws d, substantially as described and set
forth.
Third. In a castor and bedstead or like connection as described, the method
of forming and fitting the resilient inner edge or spring jaws & in and to the
castor bracket, as set forth.
Fourth. Connecting castors to bedsteads cots and other articles of furniture in
the manner described and set forth with reference to Figs. 1 to 4 of the drawings.
