OWEN ROBINSON Engineer 12 South Street Finsbury do hereby declare the
nature of this invention to be as follows:-
My Improvements are applied to and have special referance to my Patent 9979, 1885
in the Method of driveing the Rotary Shuttle. I employ a double Armed Oscillating
Bar or driver at the Back of the Shuttle, with its Fulcrum or Joint at the End of the
driving shaft The Back part of this Oscillating driver slides over a differential Annular
Surface which is secured in the Bed of the Machine concentric with the driveing
Shaft, by the action of this differential Annular Surface upon the Oscillating driver,
the Arms or Projections, advance or receed alternatly to each revolution of the
Shaft. "The Circular Shuttle is specialy constructed with recesses" to admit these
Arms at the required time so as to propel the Shuttle and at the required time so as to
propel the shuttle and allow of the free passage of the thread around it.

page_text: OWEN ROBINSON Champion Works Kettering Northamptonshire 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 relates to a method for driving circular shuttle. In the sheet of
accompanying drawings I shew Fig. 1. A a metal hub or ring shewing one bevilled
face as at a B is a T head with its stem fitting freely in A and fixed on end of the
revolving shaft as shewn. The head is slotted through as at Fig. 2. C is a steel
plate to be hereafter called the shuttle driver. This is made to fit in the slot 6 6¹ in
head B and is pivoted by a pin in its centre. D is the circular shuttle shewing the
back with the slots d d in which the two prongs c. c² of shuttle driver C work to
drive same. Fig. 2 is the head B. Fig. 3. is the shuttle driver C. Fig. 4. Back of
shuttle. Fig. 5. The circular shuttle D in its guides E E. Fig. 6. The Bevelled
Hub or ring A.
To more fully describe the working according to drawings in Fig. 1. The
parts A B. C and D all act from one centre. The ring or hub A bevilled on one end
or face is secured fast to machine frame concentric with the shaft of machine and is
recessed to allow of the stem of B to revolve freely within it. The shuttle driver
plate C is jointed in the slot. b. 6' in the head B. This plate at ca ca slides over the
bevilled face of hub or ring A and in its revolutions imparts a rocking motion to the
driver C. At each end of the driver C and opposite c² c³ are prongs or pro-
jections c & c. These are made to enter freely into the slots in the shuttle d & d¹
alternately entering and receding in each revolution as when c is out c¹ is in driving
the shuttle, making room for the thread to pass freely over the shuttle at C, and as it
continues to revolve c enters the slot appointed, and c' recedes, allowing the thread
to pass clear off the shuttle. The shuttle D is supported in the Machine by
bearings E E acting upon its periphery as at Fig. 5 allowing it to revolve freely to
the action of the driver.

page_text: Having now described the nature of my invention and the method of working
what I consider novel and original and therefore claim as the invention secured to me
by the hereinbefore Letters Patent is :
First. A metal hub or ring with a bevilled face or end as illustrated and described.
Second. A shuttle driver pivotted at its centre to a head on centre shaft and
capable of being rocked by sliding over the differential surface of hub or ring as
illustrated and described.
Third. A circular shuttle having slots at the back in a direct line with each other
across the centre and a groove round its periphery for the insertion of guides for
working as shewn and described.
