IMPROVEMENTS IN AXLETREES
Year: 1836

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, I, the
Reverend ROBERT ALLEN HURLOCK, of Whaddon, in the County of Cambridge,
Clerk, send greeting.
WHEREAS His present most Excellent Majesty King William the Fourth,
by His Letters Patent under the Great Seal of Great Britain, bearing date at
Westminster, the Eleventh day of August, in the seventh year of His reign,
did, for Himself, His heirs and successors, give and grant me, the said Robert
Allen Hurlock, His special license, full power, sole privilege and authority,
that I, the said Robert Allen Hurlock, my exors, admors, and assigns, or such
others as I, the said Robert Allen Hurlock, my exors, admors, or assigns,
should at any time agree with, and no others, from time to time and at all
times during the term of years therein expressed, should and lawfully might
make, use, exercise, and vend, within England, Wales, and the Town of
Berwick-upon-Tweed, my Invention of "IMPROVEMENTS IN AXLETREES;" in
which said Letters Patent is contained a proviso, that I, the said Robert Allen
Hurlock, shall cause a particular description of the nature of my said Inven-
tion, and in what manner the same is to be performed, to be inrolled in His
said Majesty's High Court of Chancery within two calendar months next and
immediately after the day of 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.
NOW KNOW YE, that in compliance with the said proviso, I, the said
Robert Allen Hurlock, do hereby declare the nature of my Invention, and
the manner in which the same is to be performed, are fully described and
ascertained in and by the following description thereof, reference being had to

page_text: the Drawing hereunto annexed, and to the figures and letters marked thereon,
that is to say :-
DESCRIPTION OF THE DRAWING.
Figure 1 represents my improvements applied to a carriage, the body and
wheels being shewn by dotted lines.
Figure 2 shews the axletree on a larger scale.
Figure 3 shews another view of the axletrees with part of the boxes (in
which the parts work) removed.
Figure 4 shews two views of the parts which constitute the two outer boxes
in which the axletrees turn.
Figure 5 shews two views of the parts which constitute what I call the
central box, and in which the inner ends of axletrees turn.
Figure 6 shews a method of applying the boxes.
In each of these Figures the same letters indicate similar parts. A, A, the
axletree, which, being divided into two parts, I have and shall speak of them
as the axletrees. The construction of these axletrees will readily be under-
stood by an inspection of the Drawing. B, B, the square ends of the axletrees,
which are affixed in the naves of the wheels by screws and nuts, or by other
suitable means; C, C, the inner ends of the axletrees; D, D, are projecting
circular surfaces which turn in suitable grooves formed in the boxes, and these
circular projecting surfaces act as stops and retain the axletrees in their
proper positions; E is the central box, which I prefer to be of brass, and such
is also the case with the external boxes J, J; F, F, are grooves formed in the
central box E; and K, K, are the grooves in the external boxes J, J. The
boxes are shewn as affixed to the light bar G, which bar G is affixed to the
bar H. By the foregoing description it will be seen that the wheels and their
axles revolve independently of each other, and thus obtain a steady motion.
Having thus described the nature of my said Invention, and the manner of
performing the same, I would wish it to be understood that what I claim is,
the forming or dividing the axletree into two parts, and applying the circular
projections D, D, whereby the axletrees thus produced are capable of revolving
securely and easily in the boxes E, J, J, as above described.
In witness whereof, I, the said Robert Allen Hurlock, have hereunto set
my hand and seal, the Twenty-fourth day of September, One thousand
sight hundred and thirty-six.
ROBERT ALLEN (L.8.) HURLOCK.
Signed, sealed, and delivered, being first duly
