COMPLETE SPECIFICATION.
Improvements in Castors for Articles of Furniture.
I, HENRY GORE of 8 Bott's Mews Westbourne Grove London in the County
of Middlesex, Engineer 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 invention relates to Improvements in Castors for Articles of Furniture and
consists in cutting or otherwise forming two or more openings or slits in the cone
or cup portion of such castors in such manner that when the said openings or slits.
are made and a thin strip of the material necessarily removed from the same, the
cone or cup is at once rendered flexible so that it could be contracted by outside
pressure to a smaller diameter throughout its length. To supply the outside pressure
just referred to, I preferably first cut a screw thread of a suitable pitch around a
portion of the outside of the said cone or cup and then form a large annular nut
or collar which shall fit the said thread around the cone just as an ordinary nut
should fit its bolt. For tightening up or loosening this annular nut or collar by
means of a spanner or other similar tool, I bore a few holes or cut facets or flats at
intervals around its edge which enables the spanner or other similar tool to obtain
a good grip of the said nut. To complete my invention I also form small studs or
pointed projections at intervals on the inside of the cone to enable the latter to
indent the wood of the table or other leg and thus prevent the castor from slipping
when being tightened up by means of the above referred to annular nut and
spanner.
I will now proceed to describe my invention with reference to the accompanying
drawings
:-
Fig. 1. is an elevation of my improved castor for articles of furniture, Fig. 2. is
a vertical section, and Fig. 3. is a plan of the same;
Fig. 4. shews a table-leg fitted with one of my improved castors.
The bottom end of the leg having been placed in the cone or cup a, of the castor,
the annular nut or collar b, is then tightened up by means of a spanner or other
similar tool until it will advance no further up the threads c, cut on the outside of
the said cone a. During this tightening up, the little studs or projections f, are
caused to indent the leg and thus the castor is securely fixed in its place. e; are
the slits or slots and d, are the facets.
I thus provide a castor for articles of furniture which is very simple and
efficient, requiring no screws, nails, or other similar fastenings and consequently
no holes in the furniture leg; and one that can be fixed and again removed
any number of times without damage to the said leg. It will also be seen that
a great saving of time & skilled labour is effected.
Having now particularly described and ascertained the nature of my said inven-
tion and in what manner the same is to be performed, I declare that what I
claim is :-
1. In castors for articles of furniture, the formation of slits or slots cut through
or partly through the cone or cup portion of the same, as herein described and
set forth

page_text: 2. In castors for articles of furniture the application or use of an annular
nut or collar threaded on the inside and working on a corresponding thread
around the cone or cup portion of the same, as herein described and set forth.
Dated the 7th day of April 1894.
