IMPROVEMENTS IN CASTORS
Year: 1884

page_text: I ALFRED ALLEN BARRATT of Glenwood Thames Ditton in the County of
Surrey Clerk in Holy Orders, do hereby declare the nature of said invention for
IMPROVEMENTS IN CASTORS, to be as follows:-
The improvements so far as they relate to wheel castors consist in making such
castors in or of two castings or pieces viz the upper or socket or plate piece for
fitting on the furniture or other article, and the lower or wheel piece for holding
the wheel or roller; in some cases this lower piece may itself be made in or of two
pieces and in combination with such pieces in making the upper piece with a
segmental or hemispherical bollowed base having a circular hole for receiving a
cylindrical pin projecting from a segmental or hemispherical boss fitted or fixed or
otherwise formed on the lower or wheel piece, the object being to allow of the
rotation of the lower piece in the upper; the cylindrical pin of the lower piece
when inserted in the upper piece is prevented from slipping out or down by a
screwed washer or nut or otherwise formed to effect this object. In cases whero
the lower or wheel piece is made of two pieces it is contemplated to make the pin
and boss described above separately and screw or key or otherwise fasten them
together The whole may be made of metal and the wheels or rollers of any
convenient material as at present.

page_text: I, ALFRED ALLEN BARRATT, of Glenwood, Thames Ditton, in the county of
Surrey, Clerk in Holy Orders, do hereby declare the nature of my invention for
IMPROVEMENTS IN CASTORS, and in what manner the same is to be performed, to
be particularly described and ascertained in and by the following statement :-
The improvements relate to wheel castors and consist in making such castors in
or of two castings or pieces viz the upper or socket or plate piece for fitting on the
furniture or other article, and the lower or wheel piece for holding the wheel or
roller; in some cases this lower piece may itself be made in or of two pieces-and
in combination with such pieces in making the upper piece with a segmental or
hemispherical hollowed base having a circular hole for receiving a cylindrical pin
projecting from a segmental or hemispherical boss fitted, fixed, cast or otherwise
formed on the lower or wheel piece, the object being to allow of the rotation of the
lower piece in the upper; the cylindrical pin of the lower piece when inserted in
the upper piece is prevented from slipping out or down by a screwed washer or
nut or otherwise formed to effect this object. In cases where the lower or wheel
piece is made of two pieces it is contemplated to make the pin and boss described
above separately and screw or key or otherwise fasten them together.
The whole may be of metal and the wheels or rollers of any convenient material
as at present.
The accompanying drawing will illustrate a mode of performing the invention,
like letters representing like parts in all the figures. Fig 1 is a side elevation.
Fig 2 a cross section. Fig 3 section socket piece and Fig 4 section of wheel or
castor piece. A is the socket piece-B the wheel piece-C the castor-B¹ the
segmental base-B¹ segmental boss. D washer or collar fitting in the recess D¹.
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:
•
Making castors of two or more pieces in combination with a segmental hollowed
base having a circular hole therein for receiving a pin projecting from a segmental
boss substantially as described and illustrated and for the purposes set forth.
Dated this 9th day of December 1884.
