IMPROVEMENTS IN THE CON- STRUCTION OF SHUTTLES
Year: 1879

page_text: LETTERS PATENT to John Sidney Crowley, of Manchester, in the County of
Lancaster, Engineer, for the Invention of IMPROVEMENTS IN THE CON-
STRUCTION OF SHUTTLES."
Sealed the 15th July 1879, and dated the 30th January 1879.
PROVISIONAL SPECIFICATION left by the said John Sidney Crowley at the
Office of the Commissioners of Patents on the 30th January 1879.
JOHN SIDNEY CROWLEY, of Manchester, in the County of Lancaster, Engineer.
"IMPROVEMENTS IN THE CONSTRUCTION OF SHUTTLES."
My Invention is applicable to the shuttles that run on wheels, and in consists in
securing the metal ferrules or hoops to the shuttle wheels by means of serrated
edges, thus dispensing with the customary loose pins or rivets which are liable to
damage the warp when the shuttle is passing through the shed.
In performing my Invention I cast or form a metallic ferrule provided on the
one side with a flange, and on the opposite side with a serrated rim, which, after
the hoop is driven on the wheel, is bent over to secure it to the wheel.
I purpose in some instances to dispense with the flange. I cast or form a
midfeather or midfeathers in the interior of the ferrule which retains the hoop in
position.
In some cases I make the serrations on both sides of the ferrule.

"IMPROVEMENTS IN THE CONSTRUCTION OF SHUTTLES."-
My Invention consists in dispensing with the loose pins or rivets commonly used
to fasten the hoops or ferrules on to shuttle wheels, and in securing metal ferrules
or hoops to the shuttle wheels by means of serrated edges or rims, which ferrules
or hoops I make either with or without flanges, covering partly or wholly the ends
of the shuttle wheels, and with or without a midfeather or midfeathers to retain
the hoops or ferrules in their places on the shuttle wheels. When the flange
entirely covers the ends of the shuttle wheels I cast or form on its inner side
a boss, which may be drilled to receive a centre shaft with pointed ends or
countersunk to form she centres. I can also attach the hoops or ferrules to the
shuttle wheels by rims without serrations.
And in order that my Invention may be fully understood and readily carried
into effect I will describe the accompanying Sheet of Drawings. Fig. 1 is a side
view; Fig. 2 is a longitudinal section; and Fig. 3 is an end view of a shuttle
wheel to which my improved hoop or ferrule, with a flange partly covering the end.
of the wheel is applied. a is the hoop; b is the serrated rim; and c, the flange;
d is the ordinary wood wheel; and c is the shaft or centre.
The hoop is pressed or driven on to the end of the shuttle wheel, and the serrated
rim is forced over and partly into the wheel by a milling machine or otherwise,
thus securing the hoop firmly on the wheel and preventing it from moving out of
its place.
is
Figs. 4, 5, and 6 shew a shuttle wheel with my improved hoop or ferrule having
the flange extended entirely over the end of the wheel; and with a boss on the
inside to receive the shaft or to be countersunk for a she centre. a is the hoop;
bis the rim, which in this case is made without serrations, as shewn in Fig. 7;
ff, are midfeathers; c¹ is the flange covering entirely the end of the wheel;
the boss; dis, the wheel; e is the shaft or centre; and his the she centre formed in
the boss g; the boop is forced on to the wheel, and the midfeathers penetrate the edge
of the wheel, and the rim is bent down by a milling machine or otherwise to secure
the hoop firmly on the wheel; the midfeathers keep the hoop from turning round
on the wheel.

Having thus stated the nature of my Invention, and described the manner of
performing the same, I declare that I claim, making the hoops or ferrules for shuttle
wheels with serrated edges and with or without a midfeather or midfeathers, in the
manner shewn and for the purpose described.
In witness whereof, I, the said John Sidney Crowley, have hereunto set my
hand and seal, this Twenty fifth day of July, One thousand eight hundred
and seventy nine.
JOHN SIDNEY CROWLEY. (L.S.)
