DEVICE FOR ASSISTING IN DARNING
Gerald Fitzwilliam Crusha, Bristol, England
Application September 30, 1937, Serial No. 166,467
In Great Britain April 8, 1936
5 Claims.
This invention relates to a device for assisting
(Cl. 223-100)
rubber the other end or ends of which is or are
a person when darning holes or tears in gar
suitably anchored to the outer stationary mem
ments or fabrics, such as socks, stockings, sheets,
curtains and the like, which device, which is gen—
erally known as a darning mushroom, consists
generally of a piece of wood shaped in the form
that the inner member in its normal position lies
approximately level with the outer member. 5
The outer member may be provided with a plu
ber.
The inner and outer members are so formed
of a mushroom which is placed with its head
rality of grooves or lines which may act as guides
underneath that part of the garment, herein
for the needle in order to assist in maintaining
after referred to as a sock, which it is desired to
10 darn, the device maintaining the garment in
a more or less rigid condition so that the move
ment of the needle to and fro is assisted merely
in that the edges of the material round the hole
are maintained more or less stationary and taut.
The main object of the present invention is
not only to maintain the garment in a more or
less stationary condition while darning is in
progress, but also to assist in the up and down
movement of the needle during the last part of
the darning operation while the weft threads are
being woven into the warp threads.
A'device according to the present invention
comprises two members, a stationary member
and a member wholly or partially surrounded by
25 said stationary member and resiliently mounted
within the stationary member, so that it is moved
relatively to the stationary member by means of
pressure from the needle during the darning
operation. The upper or top surface of this
30 resiliently mounted member is preferably smooth
or susbtantially so, and the word “smooth” as
used herein and in the accompanying claims with
reference to said top surface is intended to indi
cate that it is substantially free of furrows, re
35 cesses, ridges, breaks or any interruptions of a
character which might impede the passage of the
advancing point of a needle thereover, in contact
with such surface during a darning operation.
The resilient mounting may be effected by
40 means of a spring positioned between the mov
able member and the stationary member so as
to tend to keep the movable-member raised level
with the stationary member. There may be in
addition a further spring acting in the opposite
45 sense between the movable member and the ?xed
member in order to increase the sensitivity of the
device.
In one form of construction the device com
prises a mushroom, the head of which comprises
two members, one an outer stationary member,
the other being an inner resiliently ' mounted
movable member.
The movable member is rest
ing on or has anchored to its undersurface one or
more coil or suitable springs or a substance that
55 would ful?ll the same purpose such as sponge
a straight cross thread, such grooves or lines be
ing, if desired, provided on the inner member.
In the accompanying drawing:
10
Fig. l is a plan of one form of device made in
accordance with the present invention;
Fig. 2 is a section on the line 2-—2 of Fig. 1;
Fig. 3 is a plan of a modi?ed construction, and '15
Fig. 4 is a section on the line 4-4 of Fig. 3.
In the form of construction shown in Figs. 1
and 2 the device comprises a mushroom, the con
vex head of which comprises two members, one
an outer stationary member a. wholly surrounding 20
the second inner member b‘ which is resiliently
mounted within a. The bolt 0 free to move up
and down through the perforation in the base of
outer member 0., passes through two springs and
is screwed into the centre of the base of the inner 25
member 12.
The spring d acts as a cushion while the spring
e keeps the inner member I) in the position as
shown in Fig. 2. On pressure being applied to
the top of inner member b this resilient member 30
would move downwards compressing spring e,
the bolt head ,1’ following the dotted lines in the
cavity within the handle.
,
In order to use the improved device this latter
is placed in the sock with its mushroom head 35
beneath the hole or tear in the sock and the
needle is then passed over the device in a similar
way as would be used in the case of a solid mush
room darner.
In another form of construction as in Figs. 3
and 4 the device is comprised of two members,
one an outer stationary member a which only
partially surrounds inner member b. Fig. 4
shows the handle, which is ?tted with a con
tainer to hold needles and thread, a tube It hold
ing needles and compartments a‘ holding wool and
the like.
In order to use this alternative improved device
this latter is placed in the sock with its mush
room head beneath the hole or tear in the sock
and the needle is then passed over the device,
the slots or grooves g in the outer‘ member acting
as guides for the ?rst threads (i. e. the warp).
In order to facilitate the darning of the second
set of threads, (1. e. the weft) running at right
2
2,111,390
angles to the ?rst set of threads slight pressure
is exerted by the ?nger on the edge or top of the
spring biased member I) so that this is caused to
oscillate very slightly. This slight oscillation is
such as will allow the needle to be passed directly
across the ?rst set of threads without it being
necessary for the person using the needle to move
the needle up and down as is usually done in
darning, whilst still being able to make the needle
10 go over and under the ?rst set of threads.
The device according to the invention may be
of any suitable shape and size and be constructed
of any suitable material, for example the outer
member may be of wood and the inner member
15 of resilient material such as rubber, or the whole
device may be of the same material and again
may be, for example, of resinous material. The
method of holding the inner member b in posi

What I claim and desire to secure by Letters
Patent is:
1. A device for assisting in darning comprising
a stationary supporting member, and a second
member having a substantially smooth top sur
face and being resiliently mounted within the
supporting member and adapted to move rela
tively to the supporting member in response to
pressure from the needle during the darning oper
ation.
10
2. A device according to claim 1 in which the
resiliently mounted member is partially surround
ed by the supporting member.
3. A device according to claim 1 wherein
grooves are provided on the supporting member 15
to assist in positioning the threads during the
darning operation.
4. A device according to claim 1 wherein the
tion might be by sponge rubber instead of a bolt
resilient mounting comprises two springs disposed
and spring.
being particularly suitable when it is required to
between the resiliently mounted member and the 20
supporting member‘ and exerting substantially
balanced, opposing forces between said members.
5. A device for assisting in darning comprising
darn the heel or toe of a sock or like garment
a cup-shaped stationary supporting member, a
_
As an alternative arrangement, the device may
be oval or pear-shaped in elevation, such a shape
2.5 of fabric, Whilst if desired means may be incor
porated in the device, which means act as retain
ing means for needles, wool or the like when the
device is not in use.
It will be understood that the details of con
30 struction so far as concern more particularly the
position of the resilient member and the ?tting
of the resilient member within the stationary
member may be varied from the particular em
bodiment I have illustrated and described, this
35 being only given by way of example.
disc-shaped member mounted within the support 25
ing member, a spring being provided between the
base of the cup-shaped member and the disc
shaped member, the disc-shaped member being
provided with a central shank on its underside,
having a stud at its free end, a second spring
being provided between the said stud and the
underside of the cup-shaped member and a
handle on the supporting member.
