An Attachment for Glove Sewing Machines and the like for Colouring
or Dyeing the Seam during Sewing.
We, JEAN ROMEYER and ALBERT JOSSERAND, both of Place de Metz, Grenoble,
Isère, in the Republic of France, do hereby declare the nature of this invention
to be as follows:-
This invention has for its object to provide a simple and efficient attachment
for colouring or dyeing the seams of gloves or the like during the operation of the
stitching by a sewing machine.
The colouring liquor or dye is contained in a holder encased in vulcanite
celluloid or other substance which is a bad conductor of heat so as to prevent
expansion of air in the holder due to contact of the hand as this would cause the
colouring liquor or dye to be improperly expelled therefrom.
The holder is closed at its upper end by a cover soldered or screwed or otherwise
fastened thereto and at its lower end by a base plate secured by screwing or other-
wise so that it can be removed for refilling the holder, a leather rubber or like
washer ensuring a perfectly tight fit.
The device may be secured to the sewing machine by a tube passing through
the base plate of the device which tube is closed at its upper end and receives a rod
attached to the sewing machine and it can be held fast by a set screw for adjusting
the height of the device. The said rod can be fixed onto the needle carrier of the
sewing machine by means of a collar clamped by a screw which collar avoids
the necessity of boring the needle carrier while facilitating the adjustment of the
apparatus.
A tube is secured to the base plate for conveying the colouring liquor or dye
to the wick carrier and admitting air into the receiver. This tube is preferably
cylindrical internally and conical externally and contains a rod which acts as a
regulator and is flat on each side throughout its length and is bevelled at its upper
end. It may be held in position at its lower end by a pin bolt passing through
the tube and at its upper end by a screw fixed in the base plate. The said rod
regulates the passage of the air and liquid and prevents rapid ejection thereof when
the sewing machine is running at full speed.
The wick carrier is secured to the tube and contains a wick of fine fibre or other
suitable substance enclosed in a tube made with openings, which tube slides in
frictional contact in the wick carrier and is connected thereto by a fine screw and
has a milled head and is provided with a lock nut.
Any other method of support can however be employed as required according
to the sewing machines used, the present description applying more especially to
a machine of the overstitching "Brosser" type. The holder may be secured to
the table of the machine, the needle carrier only carrying the wick holding device,
which may be connected to the holder by a flexible tube.
The working of the apparatus is as follows:-The apparatus, set in motion by
the needle-carrier, rubs or brushes with its wick about the level of and near to

page_text: the wick or brush 13, which latter is contained in a tube 14 made with slots or
openings, which tube slides in frictional contact in the wick carrier or brush holder ?
so that it practically forms one piece with such holder especially towards the lower
part. The tube 14 has a fine screw thread 15 at its upper part and terminates
in a milled head 16 by means of which it may be screwed in and out of the brush
holder or wick carrier 7, a lock nut 17 serving to fix it in the required position.
The slotted tube 14 may, if preferred, be replaced by a wire-gauze tube.
The device may be secured to the sewing machine by a tube or sleeve .18 pass-
ing through the aforesaid base plate 4 of the device, which tube or sleeve is closed
at its upper end and receives with slight friction a rod 19 which can be held fast
in any desired position by a set screw 20 with a milled head for adjusting the
height of the device.
The said rod 19 is shewn fixed onto the needle carrier 22 of the sewing machine
by means of a collar 20 adapted to act as a spring which may be compressed by
a screw 21 against the said carrier.
The operation of the device is as follows:-
After firmly securing the support or bracket 19 with its collar 20 to the needle
holder 22, the mechanism is so adjusted that the end of the brush or wick 13
comes into frictional contact with the piece of material to be sewn, prior to
the stitch being formed, that is to say to the left of the needle. The formation
of objectionable loops which would result in an irregular seam is thus obviated.
The friction of the brush 13 against the glove or article being eewn causes the
fluid to be attracted by capillarity, through the brush-holder 7, and the tube 6,
air entering through such tube 6 in the condition of minute air-bulbs.
The better to ensure the admission of air, in the case of a less fluid colouring
matter, there may be fitted to the holder 1, on one side of it (as shewn in Figure 3)
a tube 23 of adequate diameter; or a central tube 24 may be similarly fitted to its
upper part, provided with a pin 25 adjustable by means of a screw (Figure 4).
The holder 1 may, if desired, be secured on the sewing-machine table, in which
case the frictional brush-holder 7 need alone be left on the needle holder, being
connected to the receiver by a flexible tube.
The advantages of the device are as follows:-
It operates without any valve, piston or spring, capillary attraction alone being
used, produced by the friction of the glove material or the like, being sewn against
the brush.
The head excluding casing 2, which surrounds the holder 1 on all sides, but
does not touch it, and which is provided with perforations 3, whereby the free
circulation of air is ensured, prevents any heat from being transmitted to the
holder 1. either from the operator's hand, or from the sun, or gas jet or other
source of heat. By thus preventing the holder 1 from becoming heated, this
casing 2 prevents also the delivery of any excess of colouring fluid-which heat
would cause and obviates the damage arising from an excessive discharge.
The employment of a slotted or wire-gauze tube, such as 14, for holding the
brush or wick 13, enables a certain rigidity to be imparted to such brush or wick,
so that it is prevented from gradually slipping back into the holder and ceasing
to rub against the material to be dyed.,
The provision of the counter-nut 17 on the brush or wick holder 14 permits the
screw 15, which supports it, to be secured against any backward movement, when
once the brush or wick 13 has been adjusted to the requisite length.
The counter-nut 17, moreover, ensures air-tight closing and effectively prevents
any of the fluid from oozing out at the top of the brush holder.
The resilient collar 20* being integral with its set screw 21, and therefore very
rigid and strong, enables the device to be fastened at any convenient point of the
needle holder 22 without involving the necessity of perforating the same.
The cylindrical supporting rod or bracket 19, fitted within a cylindrical sleeve
or tube 18 and provided with the set screw 20, enables the wick or brush 13 to
be turned at will and accurately adjusted in the required position, and the sleeve 18,
