page_text: We CHARLES LEETHEM REYNOLDS and HERBERT WAIDE REYNOLDS, both of Sultan
Factory Corset makers, and EDWARD CHARLES BEAN, mechanic, of Buckland, all of
Portsmouth in the county of Hampshire do hereby declare the nature of this invention
to be as follows:-
.
This invention refers to the use of two needles in one machine to sew two lines
of sewing at the same time and is particularly applicable for stitching.corsets.
The usual needle, bar has an addition to hold the second needle this is preferably
of an adjustable character to enable the extra needle to be adjusted the distance
required from the other needle. The shuttles used are preferably of the reciprocating
rotary kind and are placed at right angles to each other and working in opposite direc-
tions. One of the shuttle carriers is arranged to be adjusted by set screws to suit the
adjustment of the extra needle. The extra shuttle carrier is worked from the usual shuttle
driving shaft by bevel gearing. The foot or presser for the material is made double,
the extra portion.having a slot in place of a hole for the extra needle. A double
arrangement is provided for feeding the cotton.

page_text: We, CHARLES LEETHEM REYNOLDS, and HERBERT WALDE REYNOLDS, both of Sultan
Factory, Corset Makers, and EDWARD CHARLES BEAN, mechanic of Buckland, all of
Portsmouth in the county of Hampshire, do hereby declare the nature of this inven-
tion and in what manner the same is to be performed to be particularly described and
azertained, in and by the following statement:-
Our invention relates to an improved manner of using two needles in one machine,
to enable two rows of lock stitch sewing to be sewn at the same time. To enable
this invention to be properly understood, we will proceed to fully describe the same
with aid of the accompanying drawings, which show the invention applied to a machine
of the "Singer type:" The same letters of reference are used to denote the same parts
in all the views.

with view of usual shuttle arrangement.

for operating two shuttles simultaneously, taken at line X, Y, figure 3.

shuttle arrangements.

shuttles D, and (%, are arranged at right angles to each other and work in opposite
directions as shown by arrows; D³, guard ring to retain shuttle, D2, in race.
the usual shuttle driving shaft, which in accordance with this invention, is fitted
with a bevel gear wheel F, attached to a boss sleeve F¹, made adjustable as to
position on shaft E; by a set screw F; this bevel wheel, gears, with another
bevel wheel G, keyed on stud shaft G', revolving in and held by a cross bracket H,
attached to shuttle race bed D; the top of shaft G³, is attached to shuttle carrier D'.
The bed of shuttle race D, is attached to underside of table A, and can be arranged
to be adjustable as to position. This adjustability may be effected by the means
shown in drawing at figure 3, consisting of screws D, and slots D³. I, I', are the
two needles, the former being the usual one, and the latter the extra one. J, the
needle bar, having a right angle slotted extension J¹, to attach an additional needle
holder J, to. This holder is made with a side projecting screw threaded stem, J³,
to enable the holder to be moved in slot nearer to or farther from the needle 1,

will be at once understood that the shuttle race bed D, and wheel F, must be
correspondingly moved to suit the position of needle. K, the presser foot bar, K',.
the foot; this is formed with a slot K³, to suit adjustability of needle I¹. The
plate B, is also formed with a slot L in the place of a hole, also to suit the adjustability
of the needle 1. The usual cotton feeding and take up arrangements, are duplicated
to meet the requirements of the second needle.
Having now particularly described and ascertained the nature of our said
Invention, and in what manner the same is to be performed, we declare that what
we claim is :
1. The combination with the needle operating mechanism of a two needle sewing
machine and its two needles, of a shuttle operating shaft, carrying the usual shuttle
for co-operating with one of the needles, a second shuttle arranged in a plane at right
angles to the plane in which the first named shuttle operates for co-operating with the
second needle, and means for driving the second shuttle from the shuttle shaft, all
substantially as and for the purpose set forth.
2. The combination with the needle operating mechanism of a two needle sewing
machine and its two. needles, of a shuttle operating shaft carrying the usual shuttle
for co-operating with one of the needles, a second shuttle arranged at right angles
to the first named shuttle for co-operating with the other needle, a spindle G', on which
said shuttle is mounted, a gear on said spindle, and a second gear on the shuttle
operating shaft, and engaging with the first named gear, all substantially as and for
the purpose set forth.
