IMPROVEMENT IN EMBROIDERING MACHINES
Year: 1885

page_text: I, WILLIAM HUTCHINSON FARMER, of Alexandra Park, in the town and county
of the town of Nottingham, Lace Manufacturer, do hereby declare the naturė
of this invention for AN IMPROVEMENT IN EMBROIDERING MACHINES to be as
follows:-
To the platform on which each row of needles in a power shuttle embroidering
machine slide, I secure bearings in or upon which a bar the length of the machine
can be traversed, to these bars are soldered or otherwise secured as many guides
as there are needles across the machine, the bearings will vary in number
according to the width of the machine. Each bar is kept in position either with
the holes in the guides exactly opposite the points of the needles or midway
between the points. When the guide holes are opposite to the points of the
needles, and each guide being supplied with a thread, cord, tape, ribbon, length of
chenille, fringe or other ornamental trimming or material; upon the machine being
started to embroider, the said material will be securely stitched down upon the
embroidered pattern as fast as it is embroidered by the point of the needle passing
through the material in the hole of the guide and through the fabric which is
being embroidered. Each guide bar can be placed in position by the attendant at
the pentagraph at the end of the machine by means of a cam and hand lever or
equivalent means so that the guide hole carrying the thread, cord, or other
material is exactly opposite the needle or intermediately of the needles, in the
latter position the thread, cord, or other material supplied through the guides,
simply floats on the surface of the fabric, being embroidered quite clear of it, so
that such portion can be clipped off it, without in any way interfering with or
distorting the remainder of the embroidered pattern.
By such means I am enabled to produce at one process novel effects in embroidered
fabrics without having to employ hand labour or other means after the pattern is
embroidered.

I, WILLIAM HUTCHINSON FARMER, of Alexandra Park in the town and county
of the town of Nottingham, Lace Manufacturer, 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 :-
DESCRIPTION OF THE DRAWINGS.
Figure 1 is a sectional side view looking from the left end showing my
improvement as applied to each of the two rows of needles in a power shuttle
embroidering machine drawn one third the full size.
>
Figure 2 a part plan of the same at the right end of the machine.
Figure 3 a part plan at the left end.
Figure 4 a vertical view of the left end of Figure 2.
Figure 5 a vertical sectional view of part of the framing of the machine looking
from the left end and showing a side view of a cam hereafter referred to, and
Figures 6 show a sectional view and a front view of part of a bar C and two
guides D the full size.
The corresponding parts in each Figure are indicated by the same letters where
necessary. To the platform A, on which each row of needles in a power shuttle
embroidering machine slide I secure bearings B, in which a bar C the length of
the machine can be traversed, to these bars are secured as many guides as there are
needles across the machine, the bearings B will vary in number according to the
width of the machine.
The traversing of the bars and the whole of the guides simultaneously is effected
by the attendant at the pentagraph at the end of the machine by means of a hand
lever C', shown respectively in plan and side view at Figures 2 and 4, the hand
lever is secured on a vertical rod which rocks in bearings C³ attached to the
framing of the embroidering machine, the rod is provided with two arms C³, the
back ends of which are hinged to connecting links C, the other end of each link
being hinged to a swivel C5 which turns on one end of the bar C thereby allowing
the bar to be rocked in its bearings by the following means: The right end of
each guide bar has an arm D¹ shown at Figures 3 and 5 keyed on it, the front end
of which receives an axle pin secured in a vertical bar D2, the lower end of which
receives an axle pin secured in a truck bearing lever D³ which rocks on an axle
secured to the framing of the machine, the truck being operated, by a cam D₁
secured on the cam shaft of the machine, by which means when the widest
diameter of the cam is uppermost, the bar Cis rocked so as to press the upper ends
of the guides D and the cords E or other material with which they are supplied
onto the fabric F'and firmly hold the cords and fabric on to the face bar G while.
the points of the needles pass through them.
When the guides are traversed to the left as shown at Figures 2 and 3, they
occupy a position midway between the needles, but when traversed to the right
they are kept in position with the holes in their upper ends exactly opposite to
the points of the needles as shown at Figures 6.

page_text: The thread, cord, tape, ribbon, chenille, fringe, or other ornamental trimming or
material E with which each guide is provided is supplied from a spool El shown at
Figure 1, each of which is placed upon a pin in a bar E' supported by bearing
brackets E secured to the framing of the machine, from the spools, the cords or
other material are passed under a rod H carried by the lower ends of the brackets E³,
then over a rod H¹ to and through the holes in the guides D, when the rod H' is in
the position shown at Figure 1, the cords or material are held tight, but just
before the needles move in to pass into the holes in the guides the rod H¹ is
lowered to slacken the cords to ensure the needles catching them, the cords
remaining slack while the needles (each carrying its embroidering thread) advance
slightly and partly return and then wholly advance while the shuttle threads pass
through the loops formed by the needle threads, then as the needles move back
the rod H rises again.
The lowering and raising of the rods H¹ is effected by the following means, each
rod near its left end is passed through a hole in a vertical rod H³, the lower end
of which rocks on an axle pin capable of adjustment in the slot of a truck bearing
lever H which rocks on an axle secured to the framing of the machine and is
operated by a cam H³ secured on the cam shaft.
By such means. I am enabled to produce at one process novel effects in
embroidered fabrics without having to employ hand labour, or other means after
the pattern is embroidered.
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 is:-
The construction and employment of apparatus carrying guides which firmly
hold cords or other ornamental trimming or material onto the fabric while it
is being embroidered in a power shuttle embroidering machine substantially as
described and illustrated in the Drawings annexed.
