COMPLETE SPECIFICATION.
Improvements in Furniture Casters.
1 JOSHUA ENTWISLE, Manager with the Firm of E. K. Dutton & Co.,
Chartered Patent Agents, of 5 John Dalton Street, Manchester, in the County of
Lancaster, do hereby declare the nature of this invention (communicated to me
from abroad by Curtis Allen Tucker, of Westboro, Worcester County, in the
State of Massachusetts, Manufacturer, and George Arrowsmith Drysdale of
Chelsea, Suffolk County, also in the State of Massachusetts, United States of
America, Merchant,) and in what manner the same is to be performed to be
particularly described and ascertained in and by the following statement and
accompanying drawings :-
My invention relates to that class of casters on rollers which are detachably
secured and held in place in suitable sockets, and the especial object of my inven-
tion is to provide means for securing a caster socket within the end of a hollow
pipe or post
To this end, my invention consists of the parts and combinations of parts as
bereinafter described, and more particularly pointed out in the claims at the end
of this Specification.
In the accompanying drawing,
Fig. 1 is a side elevation of a hollow iron pipe or post partially broken away to
show themeaus which I preferably omploy for securing a caster socket within the
same and
Fig. 2 18 a perspective view illustrating the form of caster socket which I
preferably employ.
In making iron bedsteads and similar articles of furniture which are provided
with vertical iron posts or legs, it has heretofore been customary to close the
bottom of the bed-post or leg, and to provide each post with an extending pintle
or pin, which may be beaded over to secure a caster upon the same.
In practice, it has been found that this method of fastoning casters to posts or
pipes is unsatisfactory, as threading caster pins or pintles, or otherwise securing
these projecting pins in the bottoms of the posts is expensive, and it has also been
found that the caster pins and the rigidly secured casters are liable to be injured
or broken off when the bedsteads or other articles of furniture are shipped or
otherwise moved about.
To overcome these objections, I have provided meaus for securing the socket of
a detachable caster within the end of the pipe or post, which in practice have been
found to be exceedingly simple and practical.
Referring to the drawings and in detail, A designates a pipe or bed post, which
may be of the ordinary or approved construction, and is ordinarily formed of
hollow wrought iron pipe.
In providing the post with a caster socket according to my invention, I ordinarily
employ a sheet-metal socket D, which is provided at its lower end with a curved
serrated head or disk H, and is also provided near the centre of its body portion
with a sping tongue or projection E.
When a caster socket is to bo secured to a post, the socket is placed within the
end of the post so that the serrated disk or head H fits over and extends up around
the outside of the post A.
The end of the post or pipe A is then inserted within the molding flask or other
form of mold, and closing the lower end of the post A and surrounding the

page_text: projecting edges of the serrated disk H, I cast an ornamental re-enforcing bead, or
as it is commonly called, a chill I, which will thus form a re-enforced foot for the
bedstead post, and, at the same time, will rigidly secure the socket D within the
end of the post.
Ordinarily prefer to chill the casting I so that it will be shrunk upon the post A,
and will more rigidly engage the parts to hold them together, although it is
evident that other methods of casting may be employed, if desired.
In the dotted lines in Fig. 2, 1 have illustrated n.caster socket which is provided
with projecting spurs or extensions h, which may be used, if preferred, and where
this construction is employed, the spurs will extendito argreater distance within
the chill I, and will serve to more firmly secure the parts, although in practice I
have found.that the use of these projecting spurs is unnecessary except in cases
where the article is to be subjected to unusual strains.
The caster B which I.employ in connection with the caster socket, which is thus
secured to the bed post is provided with the ordinary caster wheel C and with an
upwardly projecting pin or shank F.having a head or shoulder G, which is adapted
to be engaged by the spring tongue E of the socket D, and to be thus detachably
secured in place.
By utilizing the ornamental re-enforcing chill on bead I for.both protecting and
ornamenting the end of the post, and for securing the caster socket in place, I have
greatly simplified the attachment of casters to posts, and have provided an extremely
simple, efficient and ornamental device
I am aware that changes may be made in the form of the caster-socket and
caster which may be employed, and I do not wish, therefore, to be limited to the
details of construction which I have shown and described.
Having now particularly described and ascertained the nature of my said 'inven-
tion and u what manner the same 18 to be performed I declare that what I
glas
1. The combination of a hollow pipe or post, a caster socket fitting within the
ond of said pipe or post, and an ornamental re-enforcing bead or chill cast upon
the lower end of said post, and securing the caster socket within said post,
substantially as described.
2. The combination of a hollow pipe or post, a sheet-motal caster socket having
a head or disk adapted to fit over and extend up around the lower end of said pipe
or post, and an oinameutal re-enforcing bead or chill cast upon the end of said
post, and securing the caster socket within said post, substantially as described.
3. The combination of a hollow, vertical, wrought-iron pipe or post, a sheet-
metal caster socket having a serrated head oi disk adapted to fit over and extend
up around the lower end of said pipe or post, and having an inwardly extending
spring tongue formed in its body portion for detachably securing a caster in
place, and an ornamental, iron ro-enforcing bead or chill cast upon the end of said
post, and securing the caster socket within the end of said post, substantially as
described.
