Year: 1787

page_text: TO ALL TO WHOM THESE PRESENTS SHALL COME, JOHN COLLINGE,
of Bridge Road, in the Parish of Saint Mary, Lambeth, in the County of
Surry, Cabinet Maker, send greeting.
WHEREAS the King's most Excellent Majesty, by His Letters Patent
under the Great Seal of Great Britain, bearing date the Second day of
November, One thousand seven hundred and eighty-seven, gave and granted
unto the said John Collinge, his executors, administrators, and assigns, His
especial licence, full power, sole priviledge and authority, that he, the said John
Collinge, his exors, adiñors, and assigns, by himself or themselves, or by his or
their deputy or deputies, servants or agents, or such other person or persons as
he, the said John Collinge, should at any time and no other, from time to time and
at all times thereafter during the term of fourteen years therein expressed, should
and lawfully might make, use, exercise, and vend, his new-invented art and in-
provement in "MAKING OF CARRIAGE AND OTHER WHEEL BOXES AND AXLETREES,
WHICH WILL BE MORE DURABLE AND LESS LIABLE TO BE OUT OF ORDER, THAN ANY NOW IN
USE;" in which said Letters Patent is contained a proviso, that if the said John
Collinge should not particularly describe and ascertain the nature of his said In-
vention, and in what manner the same is to be performed, by an instrument in
writing under his hand and seal, and cause the same to be inrolled in His
Majestie's High Court of Chancery, within one calendar month next and im-
mediately after the date of the said Letters Patent, that then the said Letters
Patent, and all liberties and advantages thereby granted, should cease, deter-

page_text: mine, and become void, as in and by the said Royal Letters Patent, referrence
being thereto had, will more fully and at large appear.
NOW KNOW YE, that in pursuance of and in compliance with the said
proviso in the said Royal Letters Patent contained, I, the said John Collinge,
do hereby disclose, discover, and describe my said Invention in manner follow-
ing; that is to say,-
Figure 1st, in the margin of these Presents, represent the longitudinal section
of a pipe wheel box, lined at each end with cast or wrought steel, mill brass, or
any other hard metal; the box may be lined in any other form upon the same
principle in any number of pieces, or cast solid in any hard metal, with one or
more internal projections or bearings for the arm of axletree to lay upon, to
diminish adhesion and friction, and contain oil or grease beneath. Figure
2d is the arm of an axletree. Figure 3d represents a hollow case to cover
and preserve the arm of axletree from wearing when in action within the
wheel box, Figure 1st, and is made of cast or wrought steel, mill brass, or
any other hard metal; this case may be made in any other form upon the
same principle, or the arm may be partially covered with any number of cases,
either all round or on the under part, to effect the same purpose and diminish
adhesion and friction. Figure 4th is a cap or reservior to contain oil or grease,
at the inner end of wheel nave; the aperture in o center, is to permit the arm
of axletree Figure 2d, to pass through before it is cased by Figure 3d;
the screw stopper on the outsid fills a space where the oil is pour'd' in.
Figure 5th is a plate or bar to cross the outer end of nave for the point of
axletree cap, Figure 3d, to bear against. Figure 6th is a cap or reservoir to
contain oil or grease, and inclose the outer end of wheel nave without the hoop,
and if required will receive the point of axletree case instead of the plate,
Figure 5th. Figure 7th is an ornament plate to cover the face of cap,
Figure 6th. Figure 8th represents the longitudinal section of a wheel nave
with the several Figures before mentioned in their proper stations.
this section is also described a pin that holds the axletree arm and cap
together, likewise bolts with screw ends which pass through the nave,
the plate, and the reserviors, and are secured by nutts at each end to pre-
vent the wheel and axletree from disunion. Figure 9th represents an axle-
tree case upon the same principle as Figure 3d, but with the addition of two
lose collars A; A, one at each end, to fit the parts B, B. These collars may be
used in any number, according to the form of the case, and made of any of the
metals before mentioned. The collars are intended to work or bear within the
wheel box instead of the fixed case, to effect the same purpose of reducing the
friction. Figure 10th represents one end of Figure 3d with the end of axletree
In

page_text: projecting beyond it to form a bearing or shoulder against the plate or bar,
Figure 5th, through which it passes, and is secured by a nutt on the other side.
Figure 11th represents a cap or reservior to contain oil or grease, resembling
Figure 6th, with an aperture in the center to permit the end of axletree to
pass through to receive a nutt on the outside by which it is secured. All which
several descriptions above written and referred to constitute my improvement
upon carriage and other wheel boxes and axletrees, and will be more durable
and less liable to be out of order than any now in use.
In witness whereof, I, the said John Collinge, have hereunto set my hand
and seal, this First day of December, in the Twenty-eighth year of the
reign of our Sovereign Lord George the Third, by the Grace of God,
King over Great Britain, France, and Ireland, Defender of the Faith,
&c., and in the year of our Lord One thousand seven hundred and
eighty-seven
