PROVISIONAL SPECIFICATION.
Improvements in Pantograph and similar Embroidering Machines.
OTHO HERBERT WEBB 41 Church Road Chorlton-cum-Hardy near Man-
chester, Factory Manager, do hereby declare the nature of this invention to be
as follows:-
Whereas in the ordinary pantagraph embroidery machines, and other machines
of a similar nature, the frame for holding the cloth to be embroidered, is so
constructed, that only one piece of material the length of the frame, can be placed
in at one time for each row of needles in the said machine, and that when these
single pieces have been embroidered they have to be taken out of the frame and
replaced by a fresh piece of material of a similar length, thus causing great delay
in the working of the machine.
My improvements consist in so altering the frame for holding the cloth, that
I am enabled to embroider any length of material without removing the same from
the frame until the whole is embroidered all through.
This is accomplished by dividing the frame into sections, by placing bars
vertically across the frame-these bars are so constructed as to afford support for
seperate rollers to be placed at the top and bottom of each row of needles on the
said machine-the cloth to be embroidered, instead of being stretched on the frame
in the usual manner, is wound on one of the rollers and stretched from it to the
corresponding roller either above or below as may be required-it is then
embroidered in the usual manner, and as the work proceeds, the cloth being
embroidered is rolled off one roller on to the other, thus enabling the whole of the
cloth originally wound on the roller, to be embroidered all through, before any of
the cloth is removed from out of the frame in the machine.

COMPLETE SPECIFICATION.
Improvements in Pantograph and similar Embroidering Machines.
I, OTHO HERBERT WEBB, of 41 Church Road, Chorlton-cum-Hardy, near
Manchester, in the County of Lancaster, Factory Manager, 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 the ordinary pantograph and other embroidering machines the frame in which
the cloth is held whilst being embroidered is constructed with gripping devices on
each of the four sides by which the cloth is stretched and held which renders it
necessary to cut the cloth into lengths before being fitted into the frame and
prevents the embroidering of any piece of material longer than the frame in which
it is stretched. When these single pieces have been embroidered the machine has to
be stopped to replace them each by a fresh piece of similar length thus causing
great delay in the working of the machine.
This invention is designed to provide for the embroidering of any length of material
without cutting it into lengths and without having to remove it from the machine
until it is embroidered throughout its whole length.

page_text: It consists essentially in constructing the oscillating frame in which the cloth is
stretched and carried to be embroidered in two or more sections with two or more
sets of rollers upon one of which a roll of cloth can be placed and upon the other
the cloth can be wound up being stretched between the two and the necessary
appliances for securing the rollers and rotating them as required.
It will be fully described with reference to the accompanying drawings in
which sufficient of a pantograph embroidering machine is shown to illustrate the
invention.

Fig. 2. Transverse sectional elevation.
Fig. 3. Sectional diagram showing the position of cloth when stretched in the
frame.
Figs. 4 and 5. Enlarged detail of ratchet for securing the rollers.
The frame work A which supports the several parts of the machine the panto-
graph appliance (not shown in the drawings) the balance lever B and suspender
rods 6 by which the cloth stretching frame D is supported the needle bars C the
shuttle bars E and the cloth plates e are all constructed and operated in the
ordinary way and will not be further described.
I divide the oscillating frame D by which the cloth under operation is carried
and in which it is stretched transversely into a number of sections F, F¹, Fl
etcætera and in each of these sections I mount one or two pairs of rollers G, H
upon one G of which a roll of cloth can be placed and upon the other one H the
cloth can as desired be rolled up and drawn off the first roller G.
The frame D is rectangular constructed of the longitudinal bars d and is divided
into the desired number of sections F, F, etcætera by the vertical transverse bars d¹.
To the transverse bars d' are bolted or otherwise fixed the brackets g and h upon
which the rollers G and H are supported. These brackets g and h and the
rollers G and H are placed one above and below each row of needles c.
In addition to the rollers G and H I place a number of guide rollers or bars K
running longitudinally of the frame over or around which the cloth (shown in
dotted lines) is passed to hold it perfectly in line with the cloth plate e and
perpendicular to the needles c as it is transferred from the roller G to the roller H.
A presser bar L or other device may be applied to the cloth to prevent it being
pulled back from the plate e as the needles are withdrawn.
On the end of each of the rollers G and H is fitted a ratchet wheel M with a
loose disc N capable of being rotated and two pawls m and n are fitted to engage
with the teeth of the ratchet wheel. The pawl m is pivoted on the upright bar di
and prevents the rotation of the roller in the reverse direction and the pawl n is
pivoted to the loose disc N and causes the roller to rotate in one direction with the
disc N. The disc is provided with holes n' to receive a bar for actuating it or it
may be fitted with a fixed or pivoted handle.
By this construction of frame the cloth to be embroidered instead of being cut
into short lengths and placed in the frame is wound upon one of the rollers pre-
ferably the bottom roller G and stretched from it to the corresponding roller H.
It is then embroidered in the usual manner and as each length of the cloth between
the two rollers is embroidered it is rolled from one to the other thus enabling the
whole piece of cloth originally wound upon the roller G to be embroidered
throughout its whole length before any of the cloth is removed from the frame D
in the machine.
Having now particularly described and ascertained the nature of the said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is :-
1. In a pantograph or other embroidering machine an oscillating cloth supporting
and stretching frame constructed of a number of sections each provided with one
or two pairs of rollers upon which the cloth under operation is wound and stretched
it being transferred from one roller to the other whereby a piece of cloth can be

page_text: embroidered throughout its whole length without being cut or removed from the
frame substantially as described.
2. In a frame D for supporting and stretching cloth for pantograph and other
embroidering machines the combination with the longitudinal bars d of the trans-
verse upright bars d' dividing the frame into sections F, F etcætera and the
rollers G and H upon one of which the cloth is placed and upon the other it is
rewound when the embroidering is complete without being removed from the frame
substantially as and for the purpose described.
3. A cloth supporting and stretching frame for embroidering machines having
the several parts constructed and arranged in combination substantially as described
and shown.
