IMPROVEMENTS IN EMBROIDERING MACHINES
Year: 1885

page_text: I SIGMUND LOUIS of 50 Newgate Street in the City of London Lace Ware-
houseman do hereby declare the nature of said invention for "IMPROVEMENTS IN
EMBROIDERING MACHINES" (a communication to me from abroad by Messrs Dognin
and Company of Rue Puits Gaillot, Lyons, France, Lace Manufacturers) to be as
follows:-
The main object of this invention is to enable an indefinite variety of widths of
pieces or widths of patterns in the same piece to be worked in one and the same
embroidering machine of the kind mostly used in Switzerland for ornamenting
light fabrics or producing what is called Swiss lace. Heretofore such machines
have been made with the needles at the same permanent distance apart all
through the same machine, and the distance once adopted must remain so and
cannot be altered. The consequence is that all patterns intended to be worked on
one of these machines must be drawn to the same width or a multiple of it.
According to this invention the needles, shuttle boxes and shuttle drivers are
made movable and adjustable on their respective bars instead of being fixed as
heretofore. By this means the aforesaid main object of the invention
and also when the fabric to be embroidered has been previously ornamented with
woven or printed designs and when it is as in most cases of an elastic nature
which does not admit of all the repeat patterns being equally distant the workınan
is nevertheless enabled to complete the ornamentation with embroidery by means
of the movable and adjustable needles, shuttle boxes and shuttle drivers which
can be adjusted separately for each pattern.
attained
The front and back bar of the so called treadle machine is provided with a
number of equidistant screwed holes for securing pincer carriages or needle holders
thereto by means of screws. Each bar is also formed with a longitudinal groove
and the pincer carriage or needle holder with a corresponding lower projecting
feather which fits in the groove thus ensuring steadiness of connection and

formed with a slot for admitting exact adjustment before fixing it which latter is
done by screwing one of the aforesaid screws into any one of the aforesaid screwed
holes. In a so called shuttle machine the needle holders, shuttle boxes and shuttle
drivers are fitted and arranged in a similar manner respectively on the front bar,
back bar and shuttle driving bar that is to say formed with slots for adjustment
before fixing which latter is done by means of screws screwed into one of the
equidistant holes formed on the said front bar, back bar and shuttle driving bar.
The shuttle box is also formed with the usual V shaped thread path or recess, and
front plate with needle hole through:

I, SIGMUND LOUIS of 50 Newgate Street in the City of London Lace Ware-
houseman do hereby declare the nature of this invention (a communication to me
from abroad by Messrs Dognin and Company of Rue Puits Gaillot Lyons France
Lace Manufacturers) and in what manner the same is to be performed to be
particularly described and ascertained in and by the following statement :-
The main object of this invention is to enable an indefinite variety of widths of
pieces or widths of patterns in the same piece to be worked in one and the same
embroidering machine of the kind mostly used in Switzerland for ornamenting
light fabrics or producing what is called Swiss lace. Heretofore such machines
have been made with the needles at the same permanent distance apart all through
the same machine, and the distance once adopted must remain so and cannot be
altered. The consequence is that all patterns intended to be worked on one of,
these machines must be drawn to the same width or a multiple of it.
According to this invention the needles shuttle boxes and shuttle drivers are.
made movable and adjustable on their respective bars instead of being fixed as
heretofore. By this means the aforesaid main object of the invention is attained
and also when the fabric to be embroidered has been previously ornamented with
woven or printed designs and when it is as in most cases of an elastic nature
which does not admit of all the repeat patterns being equally distant the workman
is nevertheless enabled to complete the ornamentation with embroidery by means
of the movable and adjustable needles shuttle boxes and shuttle drivers which can
be adjusted separately for each pattern.
The front and back bar of the so-called treadle machine are provided with a
number of equidistant screwed holes for securing pincer carriages thereto by means
of screws. Each bar is also formed with a longitudinal groove and the pincer
carriage with a correspondingly lower protecting feather which fits in the groove
thus ensuring steadiness of connection and admitting the pincer carriage to slide
along the bar. Each pincer-carriage is also formed with a slot for admitting exact
adjustment before fixing it which latter is done by screwing one of the aforesaid
screws into any one of the aforesaid screwed holes.
In a so-called shuttle machine the needle holders, shuttle boxes and shuttle
drivers are fitted and arranged in a similar manner respectively on the front bar,
back bar and shuttle driving bar that is to say formed with slots for adjustment
before fixing which latter is done by means of screws screwed into one of the equi-
distant holes formed on the said front bar, back bar, and shuttle driving bar. The
shuttle box is also formed with for example V-shaped thread path or recess and a
front plate with needle-hole through.
In order that this Invention may be more fully understood I will now proceed to
describe same with reference to the accompanying drawings. Figure 1 is a view in
plan and Figure 2 is a side elevation shewing the improvements applied to a treadle
embroidering machine. Figure 3 is a plan of the front bar of a shuttle machine
Figure 4 is a vertical cross section of the same Figure 5 is a plan of the back bar
and Figure 6 is a section of the same and Figure 7 shews the front of the shuttle
box shewing the Invention as applied to a shuttle machine all the Figures shewing

page_text: so much of an embroidering machine as will be necessary to illustrate how the
invention may be conveniently carried into effect.

Referring to Figures 1 and 2, A A shew the front and back bars of the machine
with screw holes a a at short intervals apart; B is the groove cut all along the
bars, to allow the pincer carriages sliding along; C'are the pincer carriages provided
with a feather c underneath which slides in the groove B. It is to be remarked
that the bottom of this carriage piece C has a plane surface of a sufficient width to
keep it firmly on the bars, which together with the feather c will secure a perfect
steadiness for pincers and needles. D is a slot made in each pincer carriage
permitting an exact adjustment of the carriages on the width required. E screw
for fixing carriage C. F pincers similar to those used in such machines.
Referring to Figures 3, 4, 5, 6 and 7, A is the front bar of the machine carrying
the needle holders C a are the screw holes at short intervals all along this bar as
shewn at Figure 1. B is the groove cut all along the bar A to allow the needle
holders C to slide sideways to the places required. Care needle-holders or carriages
with a feather c underneath, which slides in the groove B. D shews the needle.

it for the needle to go through-N shuttle-0 shuttle drivers which can be shifted
on the bar Qand set at the required place by means of the slot P and the screw p
Qshuttle driver bar, with screw holes q for the same purpose as the holes in the
bar H and the holes a in the.bar A.
By setting the needles to the required width, and fixing the shuttle boxes and
shuttle drivers exactly opposite an embroidery can be made of any width whatever
and even on different widths at the same time.
The advantages of the invention are as follows:-
1st With but one machine patterns may be embroidered of any width instead of
being limited to patterns of the same width with the same machine.
2nd When the fabric to be embroidered is previously ornamented with woven or
printed designs, and when it is, as in most cases, of an elastic make, which does not
allow of all the repeat pattern being equally distant, the workman is nevertheless
enabled to complete the ornamentation with embroidery by means of the movable
needles which can be adjusted separately on each pattern.
Having now particularly described and ascertained the nature of my said
Invention and in what manner the same is to be performed I declare that what
I claim as the invention communicated to me is
In embroidering machines the movable carriages C, movable shuttle boxes J, mov-
able shutter driver O and the mode and means whereby the same can be adjusted
and operated all substantially as and for the purposes set forth.
