CERTAIN IMPROVEMENTS ON LOCOMOTIVE MACHINES OR CARRIAGES
Year: 1834

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, F, GEORGE
MILLICHAP, of Birmingham, Carriage Axletree Manufacturer, 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 Thirty-first day of March, in the fourth year of His
reign, did, for Himself, His heirs and successors, give and grant unto me,
the said George Millichap, His especial license, full power, sole privilege
and authority, that I, the said George Millichap, my exors, adñiors, and
assigns, or such others as I, the said George Millichap, my exors, adñiors,
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 "CERTAIN IMPROVEMENTS
ON LOCOMOTIVE MACHINES OR CARRIAGES;" in which said Letters Patent is
contained a proviso that I, the said George Millichap, shall cause a particular
description of the nature of my said Invention, and in what manner the
same is to be performed, to be inrolled in His said 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.
NOW KNOW YE, that in compliance with the said proviso, I, the said
George Millichap, do hereby declare that the nature of my said Invention, and
in what manner the same is to be performed, are particularly described and

page_text: DESCRIPTION OF THE DRAWINGS.
Figure 1 is a side view in elevation, Figure 2 is a plan, and Figure 3 is
another side view of a locomotive machiner or carriage (represented in the
nct of overcoming an obstacle in the road), constructed according to my
Invention. In each of these Figures the same letters of referenco indicate
similar parts, a, a, being the framing of the fore part of the carriage, and b, b,
the framing of the hinder part of the carriage, the construction of which will
be evident on inspecting the Drawings. c is the main or driving shaft or axis
on which are affixed the toothed wheels d and c. This shaft c has its bearing
at on the framing 6 of the carriage, and it is capable of being moved endwise
in the bearings, in order to put the wheels daude into and out of gear, and
the shaft or axis c is retained in the desired position by the stops y placed
between the bearings and the collars h of the axis or shaft e. On to this
shaft care aflixed the two handles i; this is in case the carriage is to bo
driven by manual labour, but in case the same is to be driven by the power
of steam engines, then it will be desirable to affix cranks to the axis c. j is a
shaft or axis below the shaft or axis e, and on this shaft or axisj are affixed
the toothed wheels : and 1, and these wheels are respectively driven by the
wheels d and e, that is to say, the wheel d takes into and drives the wheel k,
and the wheel takes into and drives the wheel 6. The object of this
arrangement is to have the capability of changing the motion from slow to
fast, or fast to slow, according to the state of the road over which the carriage
is about to pass, or according as the load is great or small in comparison with
the power employed. It will be seen that the toothed wheel takes into and
drives the toothed wheels m and n, the wheel m being affixed to the axis o of
the wheels p of the carriage, the wheels p being affixed and turning with the
axis o, and this axis has bearings affixed to the framing 6 of the carriage.
The wheels n are affixed to the axis q, which has its bearings in the framing a
of the carriage, and to this axis y are affixed the wheels 1.
It will be seen
that the hinder part of the carriage is connected to the fore part by the axis
7 by means of the bearings s, through which the axis q passes, and by this
means, in the event of the wheels r meeting with an obstacle in the road, the
two parts of the carriage a, b, will allow for the inequality, as shown in Fig. 3.
In the front of the carriage is placed the stearing or guiding apparatus, the
fore wheels turning with a locking motion similar to ordinary carriages

page_text: turning on the pin, as shewn in the Drawing; and on the framing which
carries the axis of the wheel t is formed or affixed a curved toothed rack v,
which is worked by the toothed wheel u, affixed on the shaft or axis w, and
on this axis is also affixed the toothed wheel, which is driven by the toothed
wheel y, affixed on the axis of the stearing wheel A; the axis of the stearing
wheel and the axis w turn in proper bearings, as shewn by the various
Figures of the Drawing.
Having described the nature of the machinery, and the manner of com-
bining the various parts, I will proceed to describe the manner of action.
The Drawing represents the wheel d taking into the wheel k, which is the
slow motion, and consequently the most powerful. Motion being communicated
to the main shaft c, in the direction of the arrow, the same will be transferred
by means of the wheels d, k, & l, to the wheels m and n, which will give an
onward or forward motion to the carriage, and in case of coming to an ascend-
ing ground, or an obstacle in the road, the peculiar combination of the wheels
d, k, l, m, and n, will be found to act most advantageously in surmount-
ing the same. It is almost needless to add that in case a quick motion be
desired to the carriage, then the wheel e is to be put into gear with the
wheel l.
Having now described the nature of my Invention, and the manner of
carrying the same into effect, I would remark that I have not thought it
necessary to show a carriage body for goods and passengers, nor have I shown
steam engines, these forming no part of my Invention, and will be readily
applied by competent workmen; and I would further remark, that although
I have shown various parts which in their separate condition are well known,
I do not claim them when uncombined, nor combination other than hereafter
particularly defined, and it will be evident that the size and relative speeds of
the wheels inay be varied without departing from my Invention; and I would
have it understood that I do not hereby confine my claim of Invention to the
peculiar combination of the parts herein described and referred to by the
letters l, m, and n, actuated by the proper speed wheels, when such parts
I, m, and n, are combined for the more advantageous application of the
driving power of locomotive machines or carriages, as above described.
In witness whereof, I, the said George Millichap, have hereunto set
my hand and scal, this Twenty-seventh day of September, in the
year of our Lord One thousand eight hundred and thirty-four.
GEO. (L.S.) MILLICHAP.
