Improvements in Castors.
EDGAR SMALLWOOD 23, York Road, Edgbaston Birmingham do hereby
declare the nature of this invention to be as follows:-
In the ordinary method of making and securing castors to bedsteads,
furniture &c. the castor is fixed when passed on to the peg or pin, which carries
the said castor, by means of a loose washer, such washer is secured by rivetting
the end of the peg or pin, and thus secures the castor also, this method occasions
-in case of the castor having to be removed by reason of its being broken, or
damaged, considerable trouble, by having to file away the rivetted portion of
the castor peg before the washer, and castor can be released, even when this is
accomplished, the process of rivetting has again to be resorted to for securing the
new castor in its place, in addition, the castor peg in the operation is often so
damaged as to render same useless for the purpose, and to replace this peg is a
serious difficulty.
By my invention, I fix in the underside of the base of the horn of the castor, a small
piu, to this pin is secured a lever, or escutcheon, the castor pin, or peg, having an
undercut hend, or groove, near the end, and when passed thro' the horn of the
castor, the said lever, or escutcheon, is drawn as a switch, underneath the head or
into the groove in the pin, and so secures, or releases the castor at will.

I, EDGAR SMALLWOOD, of 23 York Road, Edgbaston, in the City of
Birmingham, Bedstend Manufacturers Manager, 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 :-
In the ordinary method of making, and securing castors to bedsteads,
furniture &c., the castor is fixed-when passed on to the peg, or pin, which carries
the said castor by means of a loose washer; such washer is secured by rivetting
the end of the peg or pin, and this secures the castor also, this method occasions
(in case of the castor having to be removed by reason of its being broken, or
damaged) considerable trouble by having to file away the rivetted portion of the
castor peg before the washer and castor can be released, even where this is
accomplished, the process of rivetting has again to be resorted to for securing the
new castor in its place and moreover the castor peg in the operation is often Bo
damaged as to render same useless for the purpose and to replace this peg is a
serious difficulty.

page_text: By my invention I fix in the underside of the base of the horn of the castor a
small pin, to this pin is secured a lever or escutcheon; the castor pin or peg has
An undercut head or groove near the end and when passed through the horn of the
castor, the said lever or escutcheon is drawn-as a switch-underneath the head
or into the groove in the pin and so secures or releases the castor at will.
In order to more clearly explain this my invention I have appended hereunto
an illustrative sheet of drawings upon which are figures and numbers of reference,
and in which-
Fig. 1, is a part sectional view of the invention.
Fig. 2, is an inverted plan view of the castor.
Fig. 3, and Fig. 4, are detailed plan and edge views of the fastening lever or
escutcheon.
6, represents the usual chilled casting at the lower end of a metallic bedstead
leg in which is cast the peg or pin 7. In this peg is made the groove or underout
part 8. 9 is the castor horn carrying the usual roller 10 and having the usual
bearing hole 11 to receive the peg 7. In the horn 9 is fixed (by casting or other-
wise) the peg 12 upon which is passed the lever plate 13 by means of the hole 14.
The pin 12 is slightly rivetted to prevent removal but permitting the plate to be
swung around or switched into the undercut part or neck 8, the part 15 of the plate
fitting therein. At 16 a tongue is made by slitting the metal and pushing the said
piece downwards. When the plate is in its proper position in the neck 8 by
pushing this tongue downwards, it falls behind the corner or shoulder 17 of the
horn 9 and thus effectually prevents the return of the lever plate from the neck 8.
Should however the horn of the castor become broken or damaged and require
removal, it can of course be readily removed by prizing up the tongue 16, when
the plate 13 may be turned back clear of the pin 7, and a new castor put in its
stead.
I am aware that pins 7 have been already used having an underout or neck part
such as 8, and therefore I do not claim such broadly, but;
Having now particularly described and ascertained the nature of this my said
invention, and in what manner the same is to be performed, I declare that what
I claim is :-
The combination in castors with a leg pin 7 having a neck part 8, and castor
horn 9 having a pin 12, of the lever plate 13, constructed and operating
substantially as set forth and shown upon the drawings.
Dated this 22nd day of December 1896.
