PROVISIONAL SPECIFICATION.
Improvements in Shuttle-carriers Applicable for Oscillating-shuttle
Sewing Machines.
I JOSEPH MATTHEW SELLERS of the firm of William Sellers and Sons of
Keighley in the county of York, machine maker do hereby declare the nature of this
invention to be as follows, that is to say :-
It consists of improvements in shuttle carriers applicable for oscillating-shuttle
sewing machines, by the employment of which the cost of production of said machines
is diminished while their efficiency is maintained.
To attain this, in addition to the well known bifurcated shuttle-carrier which I
modify as hereinafter described, 1 make use of a supplementary stay which I hinge to
the oscillatory shaft carrying the shuttle-carrier above referred to.
This supplementary stay is formed to have suitable arms so that it will hold the
shuttle in proper position upon its bifurcated carrier as also within its stationary
curved bearing, which may be styled the shuttle-race, by which means the small
projections usually formed on the bifurcated shuttle-carrier which are to prevent
any lateral movement of the shuttle and which require considerable care to produce
may be dispensed with, as also in like manner may the moveable curved part usually
used in connection with the curved bearing forming the shuttle-race, be dispensed
with, by constructing the shuttle-race with its curved flange part rigidly attached
to it.
An adjusting spring is used in connection with the supplementary stay in order to
cause same to remain in appropriate proximity with the shuttle when said shuttle is
in its working position, while it will hold it (said stay) in suitable position when it is
moved to allow the removal of said shuttle as will be readily understood.
In order to facilitate the placing into position of the shuttle with its bifurcated
carrier, a small projecting pin is attached to each prong of said carrier, these pins
projecting beyond the outer surface of the bearings forming the shuttle race permit
the shuttle to rest upon them and form a guide for same when it is being pressed
into position.

COMPLETE SPECIFICATION.
Improvements in Shuttle-carriers Applicable for Oscillating-shuttle
Sewing Machines.
I, JOSEPH MATTHEW SELLERS of the firm of William Sellers and Sons of
Keighley in the County of York, Machine Maker, 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, that is to say:-
It consists of improvements in shuttle-carriers applicable for oscillating-shuttle
sewing machines, whereby the cost of production of said machines is diminished
while their efficiency is maintained, and in order that my said invention may be more
readily understood, I have hereunto appended sheets of drawings illustrative thereof,
to which by figures and letters; reference is made in the following description.
Fig. 1 is an elevation shewing the shuttle carrier, shuttle, and shuttle-race.
Fig. 2 is a side view of parts shewn by fig. 1, the shuttle-race being shewn in
section. Fig. 3 is a sectional top view of parts shewn by figs. 1 and 2.

page_text: Fig. 4 is an elevation of the shuttle-carrier shewing the opposite side to that shewn
by fig. 1. Figs. 5, 6 and 7 are similar views of the shuttle-carrier to figs. 1, 2 and 3
respectively, but are illustrative of a modification in the construction of same.
To attain the object of this invention in addition to the well known bifurrated
shuttle-carrier a a, I make use of a supplementary stay which I hinge at e to the
oscillatory shaft d which carries, in a common and well known manner, the.
shuttle-carrier a a.
This stay is formed to have suitable arms 16 so that it will hold the shuttle ġ
in proper position upon its carrier a a as also to hold it within the stationary curved
bearing (which may be styled the shuttle race) e, by which means the small pro-
jections, heretofore usually formed on the carrier a a, which were to prevent any
lateral movement of the shuttle and which require considerable care to produce, may
be dispensed with, as also in like manner may the moveable curved part heretofore
usually employed in connection with the curved shuttle race e, be dispensed with by
constructing said race e so that it shall have a rigidly attached rim e¹.
The adjusting spring fis used in connection with the stay in order to cause said
stay to assume an appropriate position relatively with the shuttle g when said
shuttle g is in its working position as shewn by figs. 1, 2 and 3. Again this
said spring will hold said stay in a suitable position as shewn in broken lines
fig. 2, into which it moved to allow the removal of said shuttle g as will readily
be understood.
In order to facilitate the placing into position of the shuttle g with its carrier a a,
a small projecting pin his attached to each prong of said carrier a a, these pins h
by projecting beyond the outer surface of the race e, as shewn by fig. 3, permit the
shuttle g to rest upon them preparatory to its being pressed into proper position in
said race e, these pins / h also form a guide for the shuttle to conduct it into its said
position.
Instead of forming the stay to span the shaft d to which it is hinged, in
the manner shewn by figs. 1, 2, 3 and 4, I may construct and hinge it as shewn by
figs. 5, 6 and 7.
In order to hold the shuttle y more constantly in contact with the surfaces of its
race e, springs and I may be respectively mounted upon the carrier a a and the
stay the formation of the stay 6 being suitable for the attachment of the
spring 1, formed as shewn by figs. 5, 6 and 7, while that of the stay b may have a
spring of the shape shewn by figs. 2 and 4 at 1.
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
1. The carrier a a having pins hh and being otherwise formed as shewn, the
stay having arms and the springs fand the shaft d and the shuttle-race e
in combination all of said parts being constructed and arranged to operate
substantially as herein set forth and for the purpose specified.
2. The carrier a a formed as described, the spring k attached to or mounted upon
said carrier a a, the stay b, the shaft d and the shuttle race e in combination, all these
said parts being constructed and arranged to operate substantially as herein set forth
and for the purpose specified.
3. The carrier a a, the stay 611, the springs k and the shaft d and the spring f
in combination the same being constructed and arranged to operate substantially as
specified.
