WILLIAM ALLMAN Manufacturer 45 Villa Road Handsworth in the County of
Stafford and also of the firm of Cope Allman & Co. Unity Tube Works Icknield
Square Birmingham in the County of Warwick do hereby declare the nature of this
invention to be as follows :-
The object of my invention is to obviate the difficulties and objections now attendant
upon the breakable class of castors in general use upon Iron and brass Bodsteals, cots
and chairs by entirely dispensing with any kind or class of castor altogether and sub-
stituting in their place a smooth heini-spherical form or half ball at the extreme
bottom of the foot mounts or chill of pillars or legs.
My method of producing the desired shape and smoothness is of the most simple
character-The bottom part of mount or chill which is of the ordinary form I cast in
the usual manner by means of a top and bottom chill stock and therefore necessarily
shewing a seam down each side, but the smooth hemi-spherical form immediately
underneath is cast by means of a loose core, having a seam on the outer edge only,
thus leaving the surface of the half ball perfectly clear and smooth which I purpose
to act instead of a castor.
For the better class of Bedsteads cots and chairs I may make the hemi-spherical
shape or half ball seperately from the mount or chill and of a different metal or
material-I may also if I find it desirable make the loose half ball so that it will
rotate upon a surface or any other suitable swivel.
By the term half-ball I mean any shaped bottom allowing sufficient smoothness for
the purpose in view.
A somewhat similar fixed terminal has been used on wood furniture made in a
different form and fixed in a totally different way which could not be applied to
Iron or Brass bedsteads, cots or chairs except by my improved methods here
described.

COMPLETE SPECIFICATION.
Improvements in the Foot Terminals of Bedstead and Cot Pillars
and Chair Feet.
1, WILLIAM ALLMAN Manufacturer 45 Villa Road Handsworth in the County of
Stafford and also of the firm of Cope Allman & Co. Unity Tube Works, Icknield
Square Birmingham in the County of Warwick 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 :-
The object of my invention is to obviate the difficulties and objections now attendant
upon the breakable class of castors in general use upon Iron and Brass Bedsteads,
cots, and chairs, by entirely dispensing with any kind or class of castor altogether,
and substituting in their place a smooth hemi-spherical form at the extreme bottom of
the foot mounts or chill of pillar or leg.
My method of producing the desired shape and smoothness is of the most simple
character.
I make a chill stock or mould in 3 parts the lower and upper parts bearing the
impression of the ordinary portion of the foot mount and also a cavity to receive the
third part which consists of an iron core carrying the impression of the half ball.
Paine 1

page_text: This is placed into position in the lower half of stock first, and the upper half or
cover is closed over and secured in the usual manner before casting.
My object in having a loose core being to avoid the seain which would appear across
the half ball if the stock consisted of two halves only, in the ordinary manner..
I may if necessary cast my improved foot in any metal, in sand upon the pillar, or
separately from it and attach it afterwards.
For the better class of Bedsteads, cots & chairs, 1 may make the hemi-spherical
shape or half ball separately from the mount or chill and of a different metal or
material.
I way also make the loose half ball to rotate upon a surface or swivel and affix it to
the chill on the pillar afterwards. Figuro 4 in my drawing shows a method of
applying this, but I do not bind myself to attach it in this way only.
By the term half-ball I mean any shaped bottom allowing sufficient smoothness for
the purpose in view.
A somewhat similar fixed terminal has been used on wood furniture made in a
different form and fixed in a totally different way which could not be applied to Iron
or Brass Bedsteads, cots or chairs except by my improved methods here described.
I now proceed to describe the figures upon drawing.
Figure 1. shows the elevation and appearance of the foot terminal as cast in one
solid piece, upon the pillar or leg of bedstead. B B. is the portion of pillar and the
ordinary part of the foot terminal and E is the half ball.
Figures 2 & 3. are the upper and lower halves of the chill stock or mould-drawn
half size of figure 1. A is the cavity to receive the core A 1. B B is the impression
of the tube or pillar and ordinary portion of terminal. C. is the iron stock or mould
itself. D is the gett. or gutter for pouring, & F. is a loop or staple to lay hold of
when placing the core A 1. in position.
Figure 4. G. shows section of pillar and ordinary portion of terminal. H the
rotating half ball. I the ball bearings. K the division plato to keep them in position.
L. the brass or iron fitting which holds the half ball up and forms the connection
between the half ball and the mount G. M. is an ordinary nut cast into the mount G.
to receive the fitting.
In the better class of Bedsteads, cots or chairs, the nut M. would he cast into the
dolly or plug, and when cast brass mounts are used, the connecting fitting L could be
formed out of such mount if required.
Figure 5. shows the general appearance of Figure 4 when in elevation.
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is
1st. A foot or terminal for Iron and Brass Bedsteads and cot pillars, and chair legs,
so formed at its base to resemble a ball castor without actually being one, as described
and drawn in Figure 1.
2rid. The method of producing the same with a clear face, and without a seam upon
the half ball portion for the purpose of my invention.
3rd. Making a complete foot or terminal in one casting and without any "laying
on" pieces such as screws, pegs, or any other loose parts.
4th. Making the half ball separately from the mount or chill (of any metal or
material).
5th. In the better class, an alternative to the complete revolutions of the ball castor
by means of the rotation of the loose half ball as described.
