COMPLETE SPECIFICATION.
Improvements in the Method of Attaching Casters to Metallic
Bedsteads and such like Articles.
I, SAMUEL ILSLEY WHITFIELD of 96, Sampson Road Sparkbrook near
Birmingham in the County of Warwick Bedstead Manufacturer, 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,
reference being had to the drawings hereunto annexed and to the letters and
figures shewn thereon :-
My invention relates to the manner in which casters are attached to the feet of
metallic bedsteads and such like articles whereon casters are used.
I will describe my invention as applied to metallic bedsteads.
Hitherto the method employed in order to attach and secure the caster to the
bedstead has been by means of a washer placed upon the pin cast in with the foot of
the bedstead pillar and upon which the caster turns and then rivetting the pin, but
this method is liable to " "give" and the caster to become detached or loose by
reason of the tubular form in which it is usual to cast the pillar and foot, thus
sufficient strength is not allowed for rivetting to any great extent and consequently
any sudden pressure or force exerted upon any one caster will often cause its
rivetting to give way.
My improvements consist in casting the pillar and foot of the bedstead with a
solid wrought pin embedded therein as in the usual manner.
This pin upon which the caster turns I make with a shoulder or sinking at its
lower end and having a screw thread out thereon to receive a screw nut.
Figure 1, shews the caster detached from the bedstead.
Figure 2, shews the pillar and foot together with the shouldered pin and screw-
thread thereon.
Figure 3, is the screw nut.
Figure 4, is a complete view of the caster attached to the bedstead pillar.
Similar letters of reference relate to similar parts upon all the figures.
In order to attach the caster A to the foot of the pillar B of the metallic
bedstead the shouldered pin, C, upon the foot of the pillar is passed through the
metal carrier of the caster A and the screwnut D screwed thereon thus keeping the
caster firmly in position the shouldered screw threaded end of the pin C, being of
the same depth as the screw nut D obviously allows of the nut being screwed on
a certain distance only thereby leaving freedom for the caster A to turn upon the
pin, C.
By this method it is an easy matter to alter or change any of the casters by
simply unscrewing the nut from the pin.
I wish it to be understood that
do not confine myself to the precise details
herein set forth as I may vary the same without departing from the principle of
this my invention.
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 what I
claim is,
Firstly. The method of attaching and securing casters to metallic bedsteads and
such like articles by the use of a shouldered screwthreaded pin and screw nut upon
the foot of the bedstead pillar, substantially as herein more fully set forth and
illustrated.
Secondly. I claim, that by the use of a shouldered screwthreaded pin and nut,

page_text: great advantage is gained by additional strength simplicity and freedom of action
substantially as herein set forth and illustrated.
Thirdly. I claim, generally the construction and arrangement of parts as herein
set forth or any mere equivalents thereof by which casters are attached to
metallic bedsteads and such like articles, substantially as herein set forth and 5
illustrated.
