IMPROVEMENTS IN PORTABLE ENGINES AND OTHER WHEELED MACHINERY."
Year: 1877

page_text: LETTERS PATENT to Nathaniel Clayton and Joseph Shuttleworth, both of Lincoln,
in the County of Lincoln, Engineers, for the Invention of "IMPROVEMENTS IN
PORTABLE ENGINES AND OTHER WHEELED MACHINERY."
PROVISIONAL SPECIFICATION left by the said Nathaniel Clayton and Joseph
Shuttleworth at the Office of the Commissioners of Patents on the 5th March
1877.
NATHANIEL CLAYTON and JOSEPH SHUTTLEWORTH, both of Lincoln, in the
County of Lincoln. " IMPROVEMENTS IN PORTABLE ENGINES AND OTHER WHEELED
MACHINERY."
Our Invention relates to the under carriages of portable engines and other wheeled
machinery, and consists of a mode of constructing the under carriage (which is
composed of wrought iron or other suitable metal) as part of the rolling gear of the
portable engine or machine.
In carrying out our Invention we connect the splinter bar to the fore axle by
means of stays and diagonal braces arranged in the following manner:-The stays
proceed from the upper side of the fore axle to the splinter bar, and pass over the
same and return beneath the splinter bar to the under side of the said axle, the two
doubled portions of each stay being connected together and to the axle and the
splinter bar by means of rivets. The diagonal braces, which also form the hooks to
which the whipple trees are attached, are each secured at one extremity to the
upper side of the fore axle, and at the opposite extremity to the splinter bar, and
midway to one of the stays, the whole constituting a strong trussed frame. Space
is left at the part at which the stays are doubled over the splinter bar to form loops
through which, and also through additional loops if necessary, bolts are passed for
the attachment of the shafts.
By means of our Invention great strength and rigidity are obtained in an
economical manner in the construction of the under carriages of portable engines
and machinery.

"IMPROVEMENTS IN PORTABLE ENGINES AND OTHER
WHEELED MACHINERY.'
Our said Invention relates to the under carriages of portable engines and other
wheeled machinery, and consists of a mode of constructing the under carriage (which
is composed of wrought iron or other suitable metal) as part of the rolling gear of
the portable engine or machine.
In carrying out our said Invention we connect the splinter bar to the fore axle by
means of stays and diagonal braces arranged in the manner herein-after described,
reference being had to the Sheet of Drawings hereunto annexed.
Figure 1 of the accompanying Drawings represents a sectional elevation (the
section being taken along the line 1, 2, Figure 2) of an under carriage constructed
according to our said Invention, and Figure 2 is a corresponding plan of the same.
A are the stays which proceed from the upper side of the fore axle B to the
splinter bar C, and pass over the latter and return beneath it to the under side of
the said axle, the two doubled portions a, a¹, of each stay being connected together
by means of rivets b, b¹, with the interposition of distance pieces c, and being also
connected to the axle B and the splinter bar C by means of rivets b², bs. D are the
diagonal braces which also form the hooks E to which the whippletrees are attached;
these braces are each secured at their extremity d to the upper side of the fore
axle B by means of rivets b³, and at the opposite extremity d¹ to the splinter bar C
by rivets 6, and midway at b¹ to one of the stays A, the whole constituting a strong
trussed frame. Space is left at the part a² at which the stays A are doubled over
the splinter bar C, to form loops through which and also through additional loops
at a³, if necessary, bolts F are passed for the attachment of the shafts.
By means of our said Invention great strength and rigidity are obtained in an
economical manner in the construction of the under carriages of portable engines
and machinery.
Having now described and particularly ascertained the nature of our said
Invention, and the manner in which the same is or may be used or carried into
effect, we would observe in conclusion that what we consider to be novel and
original, and therefore claim as the Invention secured to us by the herein-before
in part recited Letters Patent is, the mode of constructing under carriages for
portable engines and other wheeled machinery, so that they form part of the rolling
gear of the same, substantially as hicrein-before described.
In witness whereof, I, the said Joseph Shuttleworth, on behalf of myself, and
the said Nathaniel Clayton, have to this our Specification set my hand and
seal, this First day of September, One thousand eight hundred and seventy
seven.
JOSEPH SHUTTLEWORTH. (L.S.)
