page_text: I HENRY EDWARD NEWTON of the Office for Patents, 6 Bream's Buildings,
Chancery Lane, in the County of Middlesex, Civil Engineer, do hereby declare the
nature of this invention to be as follows:-
In embroidery machines hitherto in use, the devices for stretching the cloth or
woven material limit the embroidery process in two directions, that is to say, either
only patterns or designs of comparatively small sizes, and corresponding to the
distance of the needles, therefore, of permanent repetition (repeat), must be
produced to make the production pay, or if patterns or designs of large extent
are to be produced, only a comparatively small number of needles can be put in
action, thus reducing the amount of work of the machine to such an extent that the
cost of production of such embroidery is too great.
Now this invention has for its object to so improve the construction of embroidery
machines, that several designs, patterns, or pictures of large extent, or repetitions of
the same, may be produced at one time independently of the needle distance (repeat),
and with a considerable number of needles per machine, or at least as many needles
as possible, and the invention consists in an arrangement of vertical rollers
applied to the frame of the embroidery machine, on which rollers the cloth or
woven material to be embroidered is wound, so that for each needle employed, a
separate piece of cloth or woven material is stretched out between two rollers.
The invention is applicable either to shuttle machines or needle machines such as
Heilman's embroidery machines.
In carrying out this invention, sets of two rows of rollers, arranged one behind the
other, are employed, and a piece of cloth or woven material is stretched between the
front rollers of one set and the back roller of the other set, on or from which the cloth
18 wound or unwound as required.

page_text: In order that the materials shall always be within the same vertical plane, it
is passed over guide pieces arranged between the rollers.-The frame which carries
the parts, rollers &c, is counterbalanced, and it is desirable to make all these parts
as light as possible.
The embroidery fields are those parts between the guides, and they may he
embroidered according to the embroidering height of the machine, and nearly the
width of the fields. After such fields have been embroidered, a fresh portion of the
material is brought forward to be embroidered, so that the embroidering of the com-
menced design is continued.
Rotary motion may be imparted to the roller in any convenient manner, but it is
preferred to use two shafts arranged at right angles to the rollers, and carrying worms
or bevelled wheels which gear with worm wheels or bevel wheels on the spindles of
the rollers. These shafts may be turned by keys, head keys, levers, cranks, ratchets
or any other convenient means
To prevent the shafts turning back, and thus slackening the stretched woven material,
any convenient means may be employed, such as set screws, pressure screws, ratchet
wheels, or friction wheels.
In order to obtain as far as possible a uniform and sufficient tension of all the pieces
of woven material in the fields from the beginning, it is necessary to provide means
for unparting rotation to each roller independent of the other. This is accomplished by
providing each roller, at the upper end, with a clutch, which, when raised vertically,
will free the roller, so that it may be turned as required to properly stretch the piece
of material belonging to said roller A spiral spring is arranged above the clutch to
hold it in gear. Instead of the device just described, one of the spur or bevel wheels
may be provided with a coupling arrangement so as to uncouple such wheel, and thereby
free the roller for separate rotation.
Each roller is provided with a step bearing having a slot at one side, through which
slot the spindle or pivot of the roller is introduced into the step bearing. The slot
is not so deep as the bearing itself, so that when the roller is inserted, the
spiral spring presses upon the roller, and keeps the spindle steady in the step
bearing. The roller may be easily removed by slightly lifting up the roller against
the pressure of the spiral spring, and drawing the spindle out through the slot.
Dated this 5th day of June 1888.

1 HENRY EDWARD NEWTON of the Office for Patents, 6 Bream's Buildings, Chancery
Lane in the County of Middlesex, Civil Engineer, 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 embroidery machines hitherto in use, the devices for stretching the cloth or
woven material to be embroidered, limit the embroidery process in two directions, that
is to say,
either only patterns or designs of comparatively small sizes, and corresponding
to the distance of the needles, therefore, of permanent repetition (repeat), must be
produced, to make the production pay, or, if patterns or designs of large extent are
to be produced, only a comparatively small number of needles can be put in action,
thus reducing the amount of work of the machine to such an extent, that the cost of
production of such embroidery is too great.
Now this invention has for its object to so improve the construction of embroidery
machines, that several designs, patterns, or pictures, of large extent, or repetitions of
the same, may be produced at one time independently of the needle distance
(repeat), and with a considerable number of needles per machine, and the
invention consists in an arrangement of vertical rollers applied to the frame of the
embroidery machine, on which rollers the cloth or woven inaterial to be embroidered
is wound, so that for each needle employed, a separate piece of cloth or woven material
19 stretched out between two rollers.
The invention is applicable either to shuttle machines or needle machines, such as
Heilmann's embroidery machines.
In the accompanying drawings:
:-
Fig. 1 shows, in front view, the invention as applied to a shuttle embroidery
machine
Fig 2 is a cross section of the frame, and
Fig 3 is a plan view
Figs. 4, 5, 6 show, in similar views, the invention, as applied in a slightly modified
form, to a Heilmann embroidery machine
In carrying out this invention, pairs of rollers a b, Figs 1, 2, and 3, and a¹ b¹,
Figs. 4, 5, and 6 (the two rollers being arranged one behind the other), are employed,
and the pieces of cloth or woven material to be embroidered are stretched between the
rollers a a of one pair, and the roller 661 of the next pair, on or from which
the cloth is wound or unwound, as required. The material may be attached to
the rollers in any convenient manner; for instance, it may be held in a slot
by, a bar.
In order that the embroidering "fields" thus formed shall always be in the same
vertical plane, no matter what may be the quantity on, the respective rollers, it is
passed over guide pieces c c¹ arranged between the rollers, and in advance

page_text: thereof. The frame which carries the parts, rollers &c, is counter-balanced
in the usual way, and it is desirable to make all these parts as light as possible.
The embroidery fields are those parts of the material marked S and S₁, between
two guides c c or c¹ c¹, and they may be embroidered according to the embroidering
height of the machine, and nearly the width of the fields -After such fields S S
have been embroidered, a fresh portion of the material is brought forward to be
embroidered, so that the embroidering of the commenced design is continued.
Rotary motion may be imparted to the rollers a a¹ and b b¹, for winding or
unwinding, in any convenient manner, but it is preferred to use two shafts d e, or d¹ e¹,
arranged at right angles to the rollers, and cariying worms s and s¹, Figs. 1 and 2,
or bevelled wheels, Figs 4 and 5, which gear with worm wheels and
01 bevel wheels on the spindles of the rollers These shafts may be turned
by keys, head keys, levers, cranks, ratchets, or any other convenient means.-
In this way, all the spindles in connection with one shaft are moved simultaneously
To prevent the shafts d e, or d¹ e¹, turning back, and thus slackening the stretched
woven material, any convenient means may be employed, such as set screws, pressure
screws, ratchet wheels, or friction wheels, not shown in the drawings
In order to obtain, as far as possible, a uniform and sufficient tension of all the
pieces of woven material in the fields from the beginning, it is necessary to provide
means for imparting rotation to each roller independently of the others. This is
accomplished by providing each roller, at the upper end, with a clutch m or m³,
which, when raised vertically, will free the roller, so that it may be turned, as
required, to properly stretch the piece of material belonging to that roller-A
spiral spring is arranged above the clutch, to hold it in gear. Instead of the device
just described, one of the spur or bevel wheels may be provided with a coupling
arrangement, so that such wheel may be uncoupled, and thereby free the roller for
independent rotation.
Euch roller is provided with a step bearing having a slot at one side, through which
slot the spindle or pivot of the rollei is introduced into the step bearing. The slot 15
not so deep as the beaning itself, so that when the roller is inserted, the spiral spring
at the top of the roller presses upon the roller, and keeps the spindle steady
in the step bearing The roller may be easily removed by slightly lifting up the
roller against the pressure of the spiral spring, and drawing the spindle out through
the slot
The number of needles used will of course depend upon the number of pieces to
be embroidered.
It will be obvious that small roller, may be used, the material being passed
fiom one to the other, but the arrangement of the rollers in pairs is most
convenient, as taking up less width, as the fabric may be unwound from the
back roller of each pair, and wound up on the front roller of the next pair, or
vice ter sa
It will be seen in the plan views, Figs 3 and 6, that the fields S and S¹ are
situate in the same vertical plane, although in Fig. 3 the two rows of rollers a and b are
on one side of this line, and in Fig. 6, the rollers a¹ and b¹ are on opposite sides of
such line. This is simply caused by the class of machine to which the rollers are
adapted, that is to say, Figs. 1, 2, and refer to a shuttle machine, in which the
shuttles of the different fields work in one line, which must be unimpeded by rollers,
whereas Figs. 4, 5, and 6 refer to a Heilmann machine, in which the needles are
carried through the woven inaterial by clips arranged and working on the two opposite
sides of the material.
With the exception of the addition to the frame of the stretching device, the
embroidering machine will be of the usual construction.
Having now particularly described and ascertained the nature of the said invention
and in what manner the same 19s to be performed, as cominunicated to me by my
foreign correspondents, I declare that what I claim is :-
1. The application to the frame of an embroidery machine, of means for stretching

page_text: or holding, in the same vertical plane, many pieces of fabric, of any length, to be
embroidered, so as to provide a number of embroidery fields in the frame at one time,
as and for the purpose set forth
2 A device for stretching many pieces of fabric to be embroidered in the frame
of an embroidery machine, and consisting of pairs of rollers a b, a' b', placed at short
distances apart, guide pieces c and c between and in advance of the pairs of
rollers means for simultaneously rotating all the rollers a or a¹ of the several
pairs, and all the rollers or of the several pairs, and means whereby the
said rollers may be rotated independently, and readily removed, as shown and
described.
