I FRANCIS BEAUCHAMP of High Cross Tottenham in the County of Middlesex
Engineer do hereby declare the nature of my said invention to be as follows:-
--
A Caster so constructed as to provide the means whereby the wheels of Casters are
kept under the circumference of the leg of the chair table or any other article for
which Casters are required-On the ordinary Casters all the pressure is brought to
hear on a centre pin or stud which very soon becomes loose and the Caster gets out of
order hut in this arrangement the pressure or weight is allways over the centre of the
wheels thus the table chair or the like can be moved with the greatest case for this
purpose I provide two plates-one of which is fixed to the (leg of the chair or any
other piece of furniture) with a hole in the centre-the other plate has a pin fixed on
the centre to revolve in the said hole on the outer edge of this plate I drill a hole for
a pin to work in with a lever attached the said lever has a hole in the end the pivot
end of the fork lever carrying the wheel works in the said hole to allow the wheel to
revolve freely at any angle on the plate that revolves I place two stops which prevents
the lever carrying the wheel from passing beyond the said plate-I sometimes use a
fixed plate with a stud fixed on the centre of the said plate and a lever working
thereon the end of the lever I provide with a hole the pivot part of the fork lever
carrying the wheel works freely in the said hole so that when the table or chair is
pushed or pulled the fork lever and the lever working on the stud turns on their axis
and allows the chair table or the like to run freely in any direction required thus
retaining the weight or pressure allways over the centre of the wheels.

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 Casters for general use whereby the wheels of the Castors
are kept under the circumference of the leg of a chair or table or any other article
for which castors are required.
In the accompanying drawings
Figure 1. is a Castor divided in the centre.
Figure 2. is an ordinary cup with six slots sawn down to allow for shrinking of the
wood.
Figure 3. is a square cup slotted in each corner for the same purpose.
Figure 4. is a Castor divided in half shewing its position under the circumference
of the log of the chair.
Figure 5. is a modification of the same cut in half.
A is a plate with a pin in the centre marked B. working in the centre hole of the
cup and marked C. D. D. are two stop studs E is a hole on the outer edge is a pin
working in hole E fixed to a plate G. H. is a fork bracket carrying the wheel with
pivot marked I. J. J. J. J. J. J. are slotsin cup. k. k. k. k. are slots in square cup L is a
roller in fork lever M is.a plate with a pivot fixed thereon marked N working in a
hole in cup and marked O. P. is a fork bracket with a pivot marked Q working in a
hole U. V. is a fork bracket working in a recess marked W. X is a plate provided with
a recess to fix to the leg of the chair Y is a pin running through plate and fork bracket
Z is the wheel.
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
The manufacture and use of Castors so constructed substantially as hereinbefore
described and illustrated in the accompanying drawings figures 1. 2. 3. 4. 5.
