Improvements relating to the Attachment of Furniture Castors.
We THOMAS CREYKE FAIRWEATHER, Maunger, EMIL HENTSCHEL, Foreman,
and THE AUTOMATIC CASTOR AND WHEEL COMPANY LIMITED, all of 34 North
Street, Manchester Square, in the County of Middlesex, do hereby declare the
nature of this invention to be as follows.-
The object of the present invention is to provide ready means for attaching
castors to the legs of cbans and other articles of furniture. The invention has
eference to that class of castors which are provided with cups or sockets wherein
are userted the extremities of the furniture legs.
The sockets of castors, as commonly made of cast metal, are conical, and the
furniture legs are shaped to fit them, the attachment being effected by ordinary
wood screws driven through holes in the cup into the wood of the leg. Another
plan which has been adopted consists in applying loosely to a recess cut around the
fumture leg near the extremity, a divided ring threaded externally, which is
embraced by the castor cap (correspondingly threaded internally), and thereby
held in an ingenious manner. This latter plan is, however, beset with manu-
facturing difficulties, owing to the cost of casting and fitting the parts, and both
arrangements have several disadvantages as regards security, if the furniture wood
be soft.
According to this invention, the socket of the castor is inade by stamping a
cylindrical cup from sheet metal, and thus cup is turned with a thread in the inside.
Another cylindrical cup, stamped and beaded on the outside, is fitted to the
furniture leg, and secured by sciews or pins. This cup is of a size to fit snugly
within the castor socket, and its thi cad corresponds with the thread of the
socket
To attach the castor, it is only necessary to screw the two threads together, and
the attachment is complete. This manner of fixing 18 exceedingly simple and
inexpensive, as the parts are easily and cheaply made and fitted.

Improvements relating to the Attachment of Furniture Castors.
We THOMAS CREYKE FAIRWEATHER, Manager, EMIL HENTSCHEL, Foreman,
and THE AUTOMATIO CASTOR AND WHEEL COMPANY LIMITED, all of 34 North
Street, Manchester Square, m the County of Middlesex, 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 the present invention is to provide ready means for attaching
castors to the legs of chairs and other articles of furniture. The invention has
reference to that class of castors which are provided with cups or sockets wherein
are inserted the extremities of the furniture legs.

page_text: The sockets of castors, as commonly made of cast metal, are comical, and the
fumiture legs are shaped to fit them, the attachment being effected by ordinary
wood screws driven though holes in the cup into the wood of the leg. Another
plau which has been adopted consists in applying loosely to a recess cut around
the furniture leg, near the extremity, a divided ring threaded externally which is
embraced by the castor cap (correspondingly threaded internally), and thereby
held in an ingenious manner. This latter plan is, however, beset with manu-
facturing difficulties, owing to the cost of casting and fitting the parts, and both
arrangements have several disadvantages as regards security, if the furniture wood
.be soft.
According to this invention the socket of the castor is made by stamping a
cylindrical cup from sheet metal, and this cup is tuined with a thread in the inside.
Another cylindrical cup, stamped and threaded on the outside. is fitted to the
furniture leg, and secured by screws or pins. This cup is of a size to fit snugly
within the castor socket, and its thread corresponds with the thread of the
Bocket.
In the accompanying drawing, Fige 1 represent the parts separate, and Fig. 2
the parts put together.
A is the chan on table leg, the end of which is turned down to a stump A'.
B is an externally threaded cup, which is secured to the stump A' by two or more
screws inserted through the bottom of the cup, as shewn in the figure.
The castor is formed with a cylindrical, internally theaded socket C, which screws
onto the cup B, and in this way the attachment is completed.
For the purposes of this invention it is preferied to make the socket C and cup B
by stamping and drawing from sheet metal in the manner now well understood, but
these parts may be formed in any other manner.
This manner of fixing is exceedingly simple and inexpensive, as the parts are
easily and cheaply made and fitted.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same 18 to be performed, we declare that what
we claim 18:-
1. The mode of attaching castors to furniture legs, which consists in turning
down the end of the leg to form a stump, adapting thei eto an externally threaded
cup, and screwing onto the cup an internally threaded socket forming part of the
castor, as here. shewn and described.
2. The improved furniture castor as herein shewn & described.
3. In a castor for furniture, the use of a cylindrical, internally threaded socket,
with an externally-threaded cylindrical cap, which is permanently secured to the
article of furniture, as shewn and described.
