IMPROVEMENTS IN LUBRICATING TRAM WHEELS, WAGGON WHEELS, CART WHEELS, ENGINE WHEELS, CARRIAGE WHEELS, AND THE WHEELS OF MACHINERY."
Year: 1876

page_text: LETTERS PATENT to William Thomas, of Resolven, Neath, Glamorgan,
Mining Engineer, for the Invention of "IMPROVEMENTS IN LUBRICATING TRAM
WHEELS, WAGGON WHEELS, CART WHEELS, ENGINE WHEELS, CARRIAGE
WHEELS, AND THE WHEELS OF MACHINERY."
PROVISIONAL SPECIFICATION left by the said William Thomas at the Office
of the Commissioners of Patents on the 30th May 1876.
WILLIAM THOMAS, of Resolven, Neath, Glamorgan, Mining Engineer. " IMPROVE-
MENTS IN LUBRICATING TRAM WHEELS, WAGGON WHEELS, CART WHEELS, ENGINE
WHEELS, CARRIAGE WHEELS, AND THE WHEELS OF MACHINERY."
My Invention of lubricating tram wheels, waggon wheels, cart wheels, engine
wheels, carriage wheels, and the wheels of machinery consists of the use of a
chambered nave in such wheels divided into compartments for holding and retaining
the lubricating material which is supplied through a small tube between the
spokes.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by
the said William Thomas in the Great Seal Patent Office on the 30th November
1876.
WILLIAM THOMAS, of Resolven, Neath, Glamorgan, Mining Engineer. "IMPROVE-
MENTS IN LUBRICATING TRAM WHEELS, WAGGON WHEELS, CART WHEELS, ENGINE
WHEELS, CARRIAGE WHEELS, AND THE WHEELS OF MACHINERY."
My Invention of lubricating tram wheels, waggon wheels, cart wheels, engine
wheels, carriage wheels, and the wheels of machinery consists of the use of a
chambered nave in such wheels divided into compartments for holding and retaining
the lubricating material, which is supplied through a small tube or duct between
the spokes.
Having thus intimated in general terms the nature or character of the said
Invention I will at once proceed (with the aid of the accompanying Drawings) to
PT
'

page_text: further and particularly describe and ascertain same, and especially the manner of
performing such Invention or carrying the same into effect, that is to say :—
DESCRIPTION OF THE DRAWINGS.
Figure 1, side elevation of my improved wheel; Figure 2, end elevation of same;
Figure 3, side sectional elevation on line C, D, Fig. 4; Fig. 4, end sectional eleva-
tion on line C³, D¹, Fig. 3; Fig. 5, sectional elevation on line A, B, Fig. 1.
In these Figures A represents the wheel, with spokes B; C, chambered nave
divided into compartments, as shewn, to which the spokes B are cast or attached; F,
receptacles or compartments in the chambered nave for oil or other lubricant; E,
feed pipe or tube for oil or other lubricant; G, axle. The oil or other lubricant is
applied through the tube or feed pipe E, and same is received in chambered nave C,
and as the lubricant drops off the axle G, after lubricating it, it is received in the
compartments F of the nave C. The tube E is so formed that the oil or lubricant
is both applied and retained in the chamber.
Having now particularly described and ascertained the nature and object of the
said Invention, and in what manner the same is to be performed or carried out in
practice, I hereby declare that I claim the said Invention of " Improvements in
Lubricating Train Wheels, Waggon Wheels, Cart Wheels, Engine Wheels, Carringe
Wheels, and the Wheels of Machinery," substantially as the same is herein-before
set forth and described and illustrated by the accompanying Drawings, it being
understood that the use of the chambered nave, supplied through a tube or duct
with lubricating material, is an important feature of the said Invention.
In witness whereof, I, the said William Thomas, have hereunto set my hand
and seal, this Twenty-seventh day of November, in the year of our Lord
One thousand eight hundred and seventy-six.
Witness,
W. M. CROCKETT,
Mining Pupil,
Resolven.
