Improvements in the Methods of Attaching Castors to and Detaching
them from Metallic Bedsteads, Cots, and such like Articles.
JAMES ALFRED CRANE 43 Villa Road Handsworth in the County of Stafford
Modeller do hereby declare the nature of this invention to be as follows:-
The object of my invention is to attach to and if necessary detach the castor
from the castor peg, in such a manner that it may be applicable to both the best
and commonest classes of bedsteads cots and such like articles.
I accomplish this result in the following simple manner :-
I make a collar of any suitable metal wide enough at its extreme ends to pass a
neck in, or under a head on, the portion of castor peg which projects through
the horn of castor, after the same is passed over it, I then close the collar tightly
against the castor peg by means of pinchers or otherwise; when the collar
effectually throttles the castor peg and prevents the return of the castor horn.
To enable the collar to be removed I so form it that its inner measurement is a
little less than the measurement of the neck of castor peg so that when closed it
leaves sufficient space for the insertion of pinchers (working out wardly) to release
it again.
By making the collar of thin metal I may cover the crown of the castor peg in
the form of a cap, which in like manner .becomes an equally effectual "throttle"
when closed into the neck or under the head of the castor peg. To enable it to be
released I leave an apperture in the side.
I do not attach any novelty to the formation of the castor peg as I am aware that
it has several times previously been made use of.

Improvements in the Methods of Attaching Castors to and Detaching
them from Metallic Bedsteads, Cots, and such like Articles.
I JAMES ALFRED CRANE, of No. 43 Villa Road Handsworth, in the County of
Stafford, Modeller, 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 :-
My invention consists of the methods hereinafter described and illustrated in the
accompanying drawing of connecting the horn part carrying the bowl or roller of
the castor to the peg on which the said horn part swivels. By my invention the
horn part of the castor can be readily detached from the castor peg and the packing
and transit of articles of furniture having castors thereby facilitated and the injury
to or breaking of the said horns and their bowls which frequently happens during
transit, when they are permanently connected to their pegs is avoided. By my
invention the castors can be more expeditiously put on at the works than by the
ordinary rivetting process.

page_text: My invention is applicable to swivelling castors in which the horn part swivels
upon the peg cast in the foot block of the metallic leg of the furniture or upon the
peg carried by the castor plate or socket and can be applied both to the best and to
the common kinds of bedsteads, cots and other like articles, either of metal or of
non-metallic material.
In carrying my invention into effect I make an open collar of metal, the said
collar being wide enough at its extreme or open ends to pass into a neck or under a
head in the portion of: the castor peg which projects through the horn of the castor.
After the horn has been passed onto the peg, I close the collar tightly within the
neck of the castor peg by means of a pair of pinchers or otherwise, when the
collar effectually throttles or fills up and projects from the neck of the castor peg
and prevents the return of the castor horn.
To enable the collar to be readily removed, 1 so form it that it can be opened
either by a pair of pinchers or by a prizing action so as to release the horn.
By making the collar of thin sheet metal in the form of a cap, the crown of the
castor peg may be covered and a portion of it forced into the neck so as to throttle
it and retain the horn on the peg. To enable the cap to be released I make an
aperture or slot in its side.
Figure 1 of the accompanying drawing represents in perspective a swivelling
castor for the leg of a metallic bedstead or other article of metallic furniture, the
horn of the said castor being attached to the castor peg according to-one of the
methods constituting my invention; Figure represents the castor peg without
the horn and Figure 3 represents the horn detached; Figure 4 represents the
separable metal collar before it is closed upon the neck of the castor peg.
After
a is the foot block of the metallic leg of the article of furniture, and 6 is the peg
cast in the said foot block; c is the neck made in that portion of the peg which
projects beyond the horn d when fitted in its place on the said peg; e is the metal
collar for securing the horn on the castor peg. The said collar e has the. form
represented in Figure 4, that is, it has the form of about three-fourths of a circle,
so that the space at f, Figure 4, between its open ends is sufficient to permit of the
passage of the said collar, by a sliding motion, into the neck c of the peg.
the horn has been put on the peg b, the collar e is passed into the neck c and by
means of a pair of plyers or pincers its open ends at are closed or brought nearly
together so as to contract the collar upon the neck and secure it in its place as
represented in Figure 1. The neck c is thereby throttled or filled up by the
collar e, a portion of the collar projecting from the neck and peg. The projecting
part of the collar e constitutes a support or seat on which the bottom of the sleeve
or tubular part of the horn d is supported in position and prevented from sliding
off the castor peg.
In order to detach the castor horn from the peg, the nose of a pair of pincers is
introduced into the space fleft at the nearly closed ends of the collar (see Figure 1)
so that by opening out the pincers, the collar is expanded and released from the
neck c, when the horn may be withdrawn from the peg.
Or for the purpose of facilitating the release of the collar from the neck of the
castor peg, the enlarged base of the peg is constructed in the manner represented
in Figures 1 and 2, that is, the shoulder of the neck where it joins the base is
bevelled or inclined as represented at g so that the closed collar can, by means of a
screw driver or other tool, be prized out of the neck in the castor peg, when it is
required to remove the said collar for releasing the horn from the peg. Or the
the same object may be obtained by bevilling or rounding the inner edge of
the collar as represented in the elevation of the inverted peg and section of the
collar and collar separately in Figure 5 where the bevilled part of the collar e is
marked' e³.
In this case the bottom of the shoulder of the neck c in the peg b. is square, the
enlarged base of the peg being without the bevil shown in Figures 1 and 2. LE
required both the base of the castor peg and the collar may be bevilled and used in:
combination.

page_text: Figure 6 represents in side elevation partly in section and Figure 7 in perspective
the horn and part of the peg of a castor in an inverted position, the said horn
being connected to the necked peg by a sheet metal cap according to my invention;
Figure 8 represents the cap detached and Figure 9 represents the same in section
upon the peg b ready to be closed upon the neck of the peg.
The said cap is marked h and has a slot 2 at one side for releasing the closed
cap from the neck of the castor peg. After the horn d has been passed onto the
the peg e the cap is placed over the projecting part of the peg as represented in
Figure 9. The middle of the cap is next contracted or pressed inwards by means
of a tool so as to cause the said part of the cap to enter the neck c and thereby
throttle it and retain the horn in its place on the peg as represented in Figures 6 and 7.
In Figure 6 the contracted cap is shown somewhat separated from the neck, for the
purpose of the better exhibiting of the parts, but in practice the contracted part
of the cap partly fills the neck in the castor peg.
To remove the cap a screw driver or other tool is introduced into the slot 2 and
by downward pressure of the said tool the cap is forced off the peg.
The necked peg and the fixing devices of the horn may be applied to socket and
plate castors as well as to necked pegs cast in the metallic feet blocks of metallic
furniture.
Having now particularly described and ascertained the nature of my inven-
tion, and in what manner the same is to be performed I declare that I claim,<
my invention:-
First. Attaching the horns or swivelling parts of castors for furniture and other
articles to and permitting of their detachment from the castor pegs by the method
hereinbefore described and illustrated in Figures 1, 2, 3 and 4 of the accompanying
drawing, that is, by the use of necked castor pegs in combination with detachable.
metal collars of the kind and applied substantially as described and illustrated.
Secondly. Facilitating the detachment of the collar from the castor peg by a
prizing action by making the lower shoulder of the neck in the castor peg bevilled
or inclined substantially as herein before described and illustrated in Figures 1 and 2
of the accompanying drawing.
Thirdly. Facilitating the detachment of the said collar from the castor peg by a
prizing action by making the inner edge of the detachable collar bevilled or
curved substantially as hereinbefore described and illustrated in Figure 5 of the
accompanying drawing.
Lastly. Attaching the horns or swivelling parts of castors to and permitting of
their detachment from the castor pegs by the method hereinbefore described and
illustrated in Figures 6, 7, 8 and 9 of the accompanying drawing; that is, by the
use with necked pegs of castors of thin sheet metal caps slotted at one side, the
said thin sheet metal caps being applied to and detached from the castor pegs
substantially as described and illustrated.
