IMPROVEMENTS IN BALL CASTORS
Year: 1885

page_text: I HARRY WINGFIELD of 15 Alfred St Warstone Lane Birmingham in the County
of Warwick Pattern Maker do hereby declare the nature of my invention for
IMPROVEMENTS IN BALL CASTORS to be as follows:-
The castor is provided with four small ball attachments, so as to give better
freedom of action, and to keep the large ball always in a central position, and from
grinding on the side and bottom of the cup, the cup is made in two halves, and is
put together with three of the small ball attachments round the side of the cup,
slightly underneath the centre, the other small ball attachment being at the top of
the cup, there are three or four small screws connected with the small ball attach-
ments, one a sett screw, slightly concaved at the end, to tighten or loosen the large
ball as required to give it freedom of action the other screws are to screw the
attachments to the cup. I beg protection of the large ball in wood for castor
purposes.

I, HARRY WINGFIELD, of 15 Alfred Street Warstone Lane Birmingham, in the
County of Warwick, Pattern Maker, do hereby declare the nature of my invention
for IMPROVEMENTS IN BALL CASTORS and in what manner the same is to be per-
formed, to be particularly described and ascertained in and by the following
statement:-
The object of my invention, is to give better freedom of action, to the large, or
principal ball, and also to keep the said large, or principal ball, in a central position
in the cup, or body, of the castor, and by so doing, considerably reduce the friction
present in ball castors, caused by the said large, or principal ball, moving, or
revolving, upon, or across wheels, or a fixed substance.
To effect my object, I place, or insert, a number of small balls, made of steel,
iron, brass, or any other suitable metal, preferably of iron, or steel, inside the cup,
or body, of the castor, for the large, or principal ball, to move, or revolve upon,
I also cast, bore, or fix, a number of chambers, inside, the said cup or body, of the
castor, into which, I place, or insert, a equal number, of the said small balls, which
said small balls, and chambers, constitute the small ball attachments, mentioned in
my provisional specification, various numbers, of small balls may be used, but
I prefer to use four balls.
The said cup or body, of the castor, I make in two halves, or parts, I place, or
insert, one ball, into a chamber, cast, bored, or fixed, at the top, of the top part, of
the said cup or body, you will observe the ball, and chamber, marked a 1 in
figure one of the drawings.
I also place, or insert, three balls, in three chambers, cast, bored, or fixed, equal
distances apart, or triangular, round the side, of the top part, of the said cup or
body, two of which, balls and chambers, are shown, in figure one of the drawings,
marked a 2 and a 3, the whole of the three, balls and chambers, herein before
described as equal distances apart, or triangular, round the said cup or body, are
shown marked, a 2 a 3 and a 4 in figure two of the drawings, And on to this
arrangement of small balls, inside the top part, of the said cup or body, I place the
said large, or principal ball, marked B in figures one and two of the drawings.
I then place, the bottom part of the said cup or body, over the said large, or
principal ball, and screw it to the said top part, of the said cup or body, as shown
in figure one of the drawings, or secure the said two parts together, by two small
screws, one each side of the said cup or body.
When the said two parts, of the said cup or body, are secured together, it is
impossible for any of the balls to come out of position.
In case the said chambers, are bored, or made, in any metal, or substance, into
which the said small balls are likely to wear, or bed, I place, or insert, a peice of
sheet steel, at the bottom of the said chambers, before the said small balls are
placed, or inserted therein, and so prevent the said small balls, from wearing, or
bedding, into the said chambers, through having a heavy weight, put upon them,
for which purpose of carrying heavy weights, these castors are specialy adapted.

page_text: The aforesaid cup, or body of the castor, may be either screwed, or riveted, to
sockets, or plates, when required as socket, or plate castors, respectively.
Figure one, shows a internal veiw of a socket castor, with the small balls in
position, Figure two shows the triangular form, of the three balls, placed round
the side of the cup or body, Figure three, shows a socket castor externaly.
my said
Having now particularly described and ascertained the nature of
invention, and in what manner the same is to be performed, I declare that what
I claim is:
1st In a ball castor, one large, or principal ball, to move, or revolve, upon one or
more small moveable balls, placed, or inserted, on or over the top of the large ball.
2nd In a ball castor, one large, or principal ball, to move, or revolve, upon or
round, one or more small moveable balls, placed or inserted, on or round the side
of the large, or principal ball.
3rd The general arrangement, form, combination, and application, of the said
small moveable balls herein before substantialy described.

the said cup or body, you will observe the ball, and chamber, marked a 1 in
figure one of the drawings.
I also place, or insert, three balls, in three chambers, cast, bored, or fixed, at equal
distances apart, or triangular, round the sides, of the bottom part, of the said cup or
body, two of which, balls and chambers, are shown, in figure one of the drawings,
marked a 2 and a 3, the whole of the three, balls and chambers, herein before
described at equal distances apart, or triangular, round the said cup or body, are
shown marked, a 2 a 3 and a 4 in figure two of the drawings, And on to this
arrangement of small balls, inside the bottom part, of the said cup or body, I place the
said large, or principal ball, marked B in figures one and two of the drawings.
I then place and screw the bottom part of the said cup to the body or upper part
over the said large, or principal ball, with the small balls lying below the centre or
middle of the main runner ball as shown in figure one of the drawings, or secure the
said two parts together, by two small screws, one each side of the said cup or body.
When the said two parts, of the said cup or body, are secured together, it is
impossible for any of the balls to come out of position.
In case the said chambers, are bored, or made, in any metal, or substance, into
which the said small balls are likely to wear, or bed, I place, or insert, a peice of

Ilaim is :

more small moveable balls, placed, or inserted, on or over the top of the large ball.
2nd In a ball castor, one large, or principal ball, to move, or revolve, upon or
round, one or more small moveable balls, placed or inserted, on or round the side
of the large, or principal ball, and below the middle or centre thereof.
3rd The general arrangement, form, combination, and application, of the said
small moveable balls hereinbefore substantialy described.
