wood boss having a metal rim rivetted thereon, but which rim has soon got loose in
consequence of shrinkage of the wood and the rivets becoming loose. Now my
improvements consist in making shuttle wheels entirely of metal, and casting them
in two parts, which are bored out to receive a casehardened metal spindle or axle.
The wheels are cast hollow or shelled out, and may have arms somewhat similar to
the arms of a wheel or pulley.

by the said Thomas Rollinson in the Great Seal Patent Office on the 19th May
1880.
THOMAS ROLLINSON, of Paddock, near Huddersfield, in the County of York,
Shuttle Maker. "IMPROVEMENTS IN THE CONSTRUCTION OF WHEELS EMPLOYED IN
SHUTTLES FOR WEAVING."
The object of this Invention is to dispense with the wood at present used in the
construction of shuttle wheels. Hitherto these wheels have been composed of a
wood boss having a metal rim rivetted thereon, but which rim has soon got loose in
consequence of shrinkage of the wood and the rivets becoming loose.
Now my improvements consist in making shuttle wheels entirely of metal, and
casting them in two parts, which are bored out to receive a casehardened metal
spindle or axle. The wheels are cast hollow or shelled out, and may have arms
somewhat similar to the arms of a wheel or pulley.
In order that these improvements may be better understood I herein give reference
to the accompanying Sheet of Drawings, wherein Fig. 1 is a front elevation and
Fig. 2 a plan view of an ordinary woollen shuttle, to which are applied my improved
wheels; Fig. 3 is a cross section of a pair of shuttle wheels constructed according
to my Invention. The wheel A. has a long boss a cast thereon, part of which is
reduced in diameter to receive the boss b of the other wheel B, both of which are
bored out, and a case hardened spindle or axle C is passed through them.
All the parts are composed of metal, and when put together resemble one piece
of metal, and pulley revolve backward and forward on the slay board of a loom.
The wheels or pulleys may have strengthening arms a, as shewn at Fig. 4, or
they may be cast hollow, as shewn at Fig. 5.
Having thus shewn and described the nature and particulars of my Invention,
and the manner of putting the same into practice, I would have it understood that
what I consider to be new, and therefore claim as my Invention is,―
The combination of the parts A, a, B, b, and C, when put together in the manner
and for the purpose substantially as herein shewn and described.
:
In witness whereof, I, the said Thomas Rollinson, have hereunto set my hand
and seal, this Fourteenth day of May, in the year of our Lord One thousand
eight hundred and eighty.
