COMPLETE SPECIFICATION.
Improvements in Fringing Machines for Producing Ornamental
Stitches, and Edging or Fringing.
I, WILLIAM FAIRWEATHER of Sackville Street, Manchester in the County of
Lancaster 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 :---
This invention is partly a new invention, and partly improvements upon the
invention for which Letters Patent were granted to me bearing date 5th June 1888
and numbered 8174, for "6
Improvements in Fringing machines for producing
ornamental stitches and edging or Fringing," and the object of this invention is
to reduce the amount of friction by simplifying the working parts, particularly in
relation to the means for closing the barbed book, thereby obtaining increased
speed and efficiency.
In order more clearly to describe this my invention I have annexed hereunto two.
sheets of drawings.
In the several views therein shown similar letters refer to similar parts: Fig. 1. is.
an end view and Fig. 2. side view of a machine constructed according to this
invention Fig. 3 is side view of part of same machine as seen from opposite side,
and Figs. 4, 5, and 6 are details drawn to an enlarged scale explanatory of closing
mechanism for closing barbed hook as herein after deseribed: In this invention
I place fast and loose pulleys band 6 on top longitudinal or driving shaft c: the
stud plate d is actuated by bevel gearing e, which is connected to said shaft: the
adjustable driving link fis attached to disc d, and the relative position of disc there-
with, the connection of swing link 9, and the corder h, the action of shaper plate j
thereon, and the means employed for imparting motion to the foot k, are the same as
described in the specification of my invention to which I have herein before referred :
In order to give a quick rise and fall motion to the presser l, I place a tappet m on
top longitudinal shaft c: this tappet actuates a lever n which is attached to a rocking
shaft 0, and by means either of a lever p or other suitable connection, the vertical
spindle is depressed at each revolution of the tappet m, thus imparting a fall motion.
to the presser which is attached to bottom end of spindle 9: Alternate rising
motion is obtained by means of the spring": For the purpose of closing the barbed
hook z when it rises, I form a closer t which I attach to rocking bar s which also
carries the bottom hook u: In order to give motion to said rocking bar s 1 form a
tappet von disc d: I attach a bell crank lever w to frame a of machine by means of
stud w¹ : I place a bowl on free end of bell crank lever w, and the lower end of
said lever I attach to a rod y: I connect the opposite end of rod y to closer t: the
tappet von disc d acting on bell crank w fitted to frame a of machine imparts motion
to connecting link y which is coupled to rocking bars carrying closer t and hook u;
the closer t and bottom hook u being both fixed to the rocking bars, are thereby
brought into a vertical position simultaneously as in Fig. 3. The closer t causes the
barbed hook to close in rising as represented in Fig. 4, and keeps it closed until it
has passed through the work, when it is released as shown in Fig. 5, the closer t
returning to its original position, and the barbed hook again descending: Fig. 6 is.
a plan view of Figs. 4 and 5: By the means herein above described, when the
swing link g is brought into position shown by dotted lines in Fig. 2 on drawings,
the presser is raised by the spring, the tappet m causes the presser to descend
before the return of swing link g and corder h to their original positions: the thread
is carried by the hook h' under the presser in the form of a loop: the length of loop
required which is thus formed, may be regulated, in addition to the adjustable studs.
on disc d, by the length of corder employed: If a loop of greater length is required

page_text: to be formed, I employ a long corder h and swing link g which I suspend from an
upper stud h³ as shown on drawings, but if a loop of less length is required to be
formed, I then employ a shorter corder and swing link g, which I suspend from
lower stud h². The rocking bar s, and in combination therewith the closer t and
bottom hook u, may be actuated by mechanism such as is ordinarily employed in like
machines, in lieu of tappet » on disc d and bell crank was herein before described.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed, I declare that what I
claim is:
1st. In a machine that is employed for producing ornamental stitches and edges or
fringing, the combination and arrangement of the several parts forming said machine
in the manner, and for the purpose substantially as herein before described.
2nd. In a machine that is employed for producing ornamental stitches and edges
or fringing, said machine being constructed either of the form shown on accom-
panying drawings or of the ordinary form, the use of closing mechanism for closing
the barbed hook z by means of a combination of the closer t and the rocking bar s
substantially in the manner herein before described and illustrated.
3rd. In a machine that is employed for producing ornamental stitches and edging
or fringing the use of closing mechanism for closing the barbed hook z by means of
the rocking bar s in combination with a connecting link y and bell crank lever w,
which may be actuated by a tappet placed either on a disc as shown on drawings, or
in other preferred position.
4th. In a machine that is employed for producing ornamental stitches and edges or
fringing the use of a tappet m, placed on top longitudinal or driving shaft, in com-
bination with a vertical spindle to which a presser is connected, for the purpose of
giving quick rise and fall motion to said presser, substantially in the manner herein
before described.
