page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, WILLIAM
WALKER, of George Yard, Crown Street, Soho, in the County of Middlesex,
Coach Smith, send greeting.
WHEREAS Her present most Excellent Majesty. Queen Victoria, by. Her
Letters Patent under the Great Seal of Great Britain, bearing date at West-
minster, the Second day of March, in the sixth year of Her. reign, did,
for Herself, Her heirs and successors, give and grant unto me, the said
William Walker, my exors, adiñors, and assigns, Her. especial. licence, full
power, sole privilege. and authority, that I, the said William Walker, my
exors, admors, and assigns, and such others as I, the said William Walker,
my exors, admors, or assigns, should at any time agree. with, and no others,
from time to time and at all times thereafter during the term of years therein
expressed, should and lawfully might make, use, exercise, and vend, within that
part of Her Majesty's United Kingdom of Great Britain and Ireland called
England, Her Dominion of Wales and the Town of Berwick-upon-Tweed, my.
Invention of "CERTAIN IMPROVEMENTS IN THE MANUFACTURE OF SPRINGS AND
AXLES FOR CARRIAGES;" in which said Letters Patent there is contained a
proviso that I, the said William Walker, shall cause a particular description of
the nature of my said Invention, and in what manner the same is to be
performed, under my hand and seal, to be inrolled in Her Majesty's High
Court of Chancery within six calendar months next and immediately after
the date of the said in part recited Letters Patent, as in and by the same;
reference being thereunto had; will more fully and at large.appear.

page_text: NOW KNOW YE, that in compliance with the said proviso, I, the said
William Walker, do hereby declare that the nature of my said Invention, and
the manner in which the same is to be performed, are fully described and
ascertained in and by the following statement thereof, reference being had
to the Drawings hereunto annexed, and to the letters and figures marked

according to my patented improvements. a, b, c, are three plates of steel of
uniform thickness throughout, the edges of which are tapered off towards
each extremity, as shewn in the plan Figure 2. d is a similar but larger
plate of steel, the ends of which are bent up, and formed into eyes to receive
the shackles or connecting bolts. The plates may be proportioned in thick-
ness, as well as in the number employed, to the work for which they are
required. The plates may be held together in their respective places by a
bolt passing through the middle, or by clamps placed externally, as at present
commonly practised. What I claim as being new and of my Invention, is
the manufacture of springs for carriages or other purposes of steel plates of
uniform or nearly uniform thickness throughout, tapered off on the edges as
shewn and described. I also claim the manufacture of springs tapered on the
edges, as described and shewn from plates of steel, diminishing in thickness
from the middle towards each end.
My improvements in axles are shewn in Figures 3, 4, and 5. Figure 3: A is
the axle which is hollow nearly up to the shoulder, and terminates in a screwed
end a... B is a shoulder forged on the axle. c is a small hole tapped through
the screwed end of the axle, and communicating with the hollow space within
the axle, which forms a reservoir for oil. d, d, are small holes perforated at
intervals along each side of the axle into the oil chamber, through which
the oil circulates when the wheel is in motion. Figure 4 is a longitudinal
section through the middle of the box and axle. A, as before, is the axle.
B, the shoulder. C, the apertures for oiling. d, d, openings into the oil
reservoir. D, D, the box. E, E, is a second shoulder and cap, which screws
on to the end of the axle after the box is in its place. There are two
collars ff, placed one at each end of the box, between the box and the
shoulders B and E, to prevent the escape of oil in either direction, the box
does not, however, bear hard upon the leathers, but takes a bearing upon the
metal cones g and h. I is an end cap, the periphery of which is divided into
eight or more sides, in each of which there is an oblong hole to admit the

page_text: screws k, k, to be inserted on opposite sides in the hole C when the shoulder
is screwed up tight. The screws k, besides closing the orifice of the oil
chamber, keep the cap and shoulder E from turning round, and thereby
prevents the wheel from coming off. Figure 5 is an external view of the box
and axle complete; references as before.
What I claim as my Invention is the improved form of axle, with perforated
internal oil reservoir and box with double shoulders os shown and described
In witness whereof, I have hereunto set my hand and seal, this Second
day of September, One thousand eight hundred and forty-three.
AND BE IT REMEMBERED, that on the Second day of September, in
