We, JOHN PARRY and FREDERICK JOSEPH WYTHES, trading together as Parry,
Wythes & Co., of Eagle Foundry, Broad Street, Birmingham, Warwickshire,
Manufacturers, do hereby declare the nature of this invention to be as follows:-
In the ordinary method of attaching castors to the legs of bedsteads and other
articles of metallic furniture a vertical centre pin around which the castor revolves
is cast into the leg and projects for a certain distance beyond the lower end. On this
projecting pin the castor is threaded and is there secured by the outer end of the pin
being rivetted over. As the castors often get broken in transit they are, when secured
in this manner, difficult and expensive to renew.
By our invention castors can be secured on their pins by any inexperienced person
without rivetting thus enabling the castors to be packed separately from the bedstead
and readily attached thereto on arriving at their destination.
In carrying out our invention we form in the said pin which is cast into the leg and
near its outer end a recessed neck. We provide a sheet metal washer, preferably of
circular shape, having a central hole about the same size as the said neck. This washer
is divided in radial lines extending from its central hole towards its periphery thus
forming a number of tongues pointing to the centre of the washer. These tongues are
pressed or bent upwards thereby separating them farther from each other and
enlarging the central hole of the washer so that it will pass on to the said pin.
To attach the castor it is threaded on to the pin in the ordinary manner; the
washer is then threaded on to the pin and flattened by a tubular tool and a mallet
or by other means so as to cause its tongues to resume their normal position and
engage with the neck thus firmly fixing the washer and castor on to the pin.

page_text: In applying our invention to those castors in which the horns carrying the roller
are fixed to the vertical pin and the pin turns loosely in a hole in the leg to which the
castor is attached, we provide a neck near the upper end of such pin and fix the split
washer in the leg in such a position that when the pin is inserted in the hole in the
leg the tongues of the washer will engage with the neck and secure the castor in
position but permit of its turning round.
In some cases we form a small head or swell on the pin, instead of a neck, the
divided washer being sprung over such swell or head and secured as above
described. .

WO, JOHN PARRY and FREDERICK JOSEPH WYTHES, trading together as Parry,
Wythes & Co., of Eagle Foundry, Broad Street, Birmingham, Warwickshire,
Manufacturers, 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 :-
In the ordinary method of attaching castors to the legs of metallic bedsteads and
other articles of metallic furniture a vertical centre pin around which the castor
revolves is cast into the leg and projects for a certain distance beyond the lower end.
On this projecting pin the castor is threaded and is there secured by the outer end of
the pin being rivetted over. As the castors often get broken in transit they are, when
secured in this manner, difficult and expensive to renew.
By our invention castors can be secured on their pins by any inexperienced person
without rivetting thus enabling the castors to be packed separately from the bedstead
and readily attached thereto on arriving at their destination.
In carrying out our invention we form in the said pin which is cast into the leg and
near its outer end a recessed neck. We provide a sheet metal washer, preferably of
circular shape, having a central hole about the same size as the said neck. This washer
is divided in radial lines extending from its central hole towards its periphery thus
forming a number of tongues pointing to the centre of the washer. These tongues
are pressed or bent upwards thereby separating them farther from each other and
enlarging the central hole of the washer so that it will pass on to the said pin.
On the accompanying drawing Fig. 1 represents in elevation and Fig. 2 in plan
a castor secured to the leg of a metallic bedstead or other article of metallic furniture
according to this invention; Fig. 3 is a separate view of the pin on which the castor
turns and the lower part of the said leg separately, and Fig. 4 represents the said
metal washer in sectional elevation and plan and Figs. 5 and 6 illustrate the operation
of attaching the castor on to its central pin.
A is the central pin on which the castor D turns and which is cast into the leg B
in the usual manner and having the recessed neck a near its outer end. is the sheet
metal washer having the central hole c¹ a little larger than the neck a and slit or
divided in radial lines from the central hole towards its periphery thus forming the
tongues c². These are bent upwardly by dishing the washer thus separating the
tongues farther from each other and enlarging the central hole c¹ so that it will pass
on to the pin A.
After the castor D has been threaded on to the pin A the washer C is then threaded
on to the pin as shewn in Fig. 5 and the washer is then flattened by striking a circular
tool E which fits over the pin A and brings the tongues back to their original
position and the central hole c² to its original size so as to engage with the neck a and
thus be secured to the pin and prevent the castor coming off.

page_text: In applying our invention to those castors in which the horn prece carrying the
roller is fixed to the vertical pin and the pin turns loosely in a hole in the leg to which
the castor is attached we provide a neck near the upper end of such pin and fix the
split washer in the leg in such a position that when the pin is inserted in the hole in
the leg the tongues of tho washer will engage with the neck and secure the castor
in position but permit of its turning round. The application of our invention to
attaching this kind of castor to the legs of metallic furniture is illustrated by Figs. 7.
and 8. F is the vertical pin of the castor which is fixed to the horn piece Ď and fits
loosely in the vertical hole in the leg B. The upper end f¹ of this pin is reduced
in diameter smaller than the body of the pin and is necked down at for the
washer to engage in. C is the divided washer which is similar to that shewn in Fig. 4.
The washer is cast in the leg centrally with the hole band with the tongues pointing
downwardly (see Fig. 8) and when the pin F of the castor is inserted in the hole the
upper end of the pin passes through the hole c' in the washer and the shoulder
formed by the end of the body part 2 of the pin comes in contact with the ends of
the tongue and as the pin F is driven home the washer is flattened and the
tongues engage with the neck f³ thus securing the castor position but allowing of
its turning round.
هم
In some cases we form a small head or swell g (see Fig. 9) on the pin A instead of
a recessed neck and the divided washer C is secured over such swell or head by striking
with a tool as above described with reference to Figs. 5 and 6.
Instead of the washer having several tongues as above described a single tongue
may be employed as for instance in the modification illustrated by Fig. 11 which, when
the washer has been threaded on to the pin A and flattened, will similarly engage in
the neck a¹.
Having now particularly described and ascertained the nature of our said Inven-
tion, and in what manner the same is to be performed, we declare that what
we claim is :-
1st. Attaching castors to the centre pins which are fixed in the legs of metallic
bedsteads and other articles of metallic furniture, by means of a dished washer having
inwardly projecting tongues which, when the washer has been threaded on to the pin
and flattened, engage in a neck in the pin or with a head on the pin, substantially as
set forth.
•
2nd. Attaching castors to the centre pins which are fixed in the legs of metallic
bedsteads and other articles of metallic furniture by means of a washer having an
inwardly projecting tongue which, when the washer has been threaded on to the pin
and flattened, engages in a neck in the pin or with a head on the pin, substantially as
set forth.
3rd. Attaching castors to the legs of metallic bedsteads or other articles of metallic
furniture by means of a dished washer cast in such leg and having an inwardly
projecting tongue or inwardly projecting tongues and the upper end of the central
pin of the castor having a recessed neck so arranged that when the said central pin is
inserted in the hole in the leg and driven home the washer will be flattened and the
tongue or tongues caused to engage with the recess in the pin, substantially as sot
forth.
4th. Forming a recessed neck near the outer end of the central pin of a castor, or
on which a castor turns, for the purpose and substantially as set forth.
