PROVISIONAL SPECIFICATION.
Improvements in Connecting Rods.
We, STEPHEN ALLEY, and JOHN ALEXANDER MACLELLAN, of the Sentine
Works, Polmadie, in the County of Renfrew, North Britain, Engineers, do hereby
declare the nature of this invention to be as follows, that is to say :-
Our said invention has for its object to improve the construction of connecting
rods and to provide for the adjustment of the brasses or bearing pieces at both end
joints by one action.
In carrying out our invention the main part or body of the connecting rod is made
with recesses at its opposite ends for half brasses or bearing pieces for the pins
upon which the rod is jointed; and the remaining half brasses or bearing pieces
are held in caps which are jointed to the ends of the rod.
The bearing caps are jointed, by preference, to opposite sides at the opposite
ends of the connecting rod; and a rod or long bolt crossing the middle of the rod
diagonally is employed for holding both caps in position. This long bolt passes
through holes or notches in the connecting rod ends and in the bearing caps, a head
formed on one end of it bearing on the outside of one cap and a nut screwed on the
other end bearing on the outside of the other cap. Springs are by preference
applied round the long bolt in a manner to keep the bearing caps close to the head
and nut respectively and thereby prevent rattling of the parts when a slight
slackness is produced by wear. The long bolt whilst securing the bearing caps,
contributes to the strength of the rod.
Dated this Tenth day of March 1891.

COMPLETE SPECIFICATION.
Improvements in Connecting Rods.
We, STEPHEN ALLEY, and JOHN ALEXANDER MACLELLAN, of the Sentinel
Works, Polmadie, in the County of Renfrew, North Britain Engineers do hereby
declare the nature of this invention and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following
statement, that is to say :-
Our said invention has for its object to improve the construction of connecting
rods, and to provide for the adjustment of the brasses or bearing pieces at both end
joints by one action.
And in order that our said invention and the manner of performing the same may
be properly understood, we hereunto append a sheet of explanatory drawings, to
be hereinafter referred to, and shewing an example of our improved connecting rod.
Figure, 1, of the drawings is an inside face view of a cap attached to one end of
our improved connecting rod,
Figure, 2, is a longitudinal section of the rod,
Figure, 3, is an inside face view of a cap attached to the other end of the rod,
Figure, 4, is a plan, and Figure, 5, is a transverse section of the rod at its middle
part.
In these drawings the same reference letters are used to mark the same or like
parts wherever they are repeated.
In carrying out our invention, the main part or body, A, of the connecting rod is
made with recesses, B, at its opposite ends, C, D, for half brasses or bearing

page_text: pieces, E, for the pins upon which the rod is jointed; and the remaining half
brasses or hearing pieces, F, are held in caps, G, which are jointed to the ends, C, D,
of the rod. The bearing caps, G, are jointed by preference, to opposite sides at
the opposite ends, C, D, of the connecting rod; and a rod or long bolt, H, passing
through the rod which is hollow, and crossing at the middle of it is employed for
holding the caps, G, in position. This long bolt, H, passes through holes or
notches, I, in the connecting rod ends, C, D, and in the bearing caps, G, a head, K,
formed on one end of it, bearing on the outside of one cap, G, and a nut, L, screwed
on the other end, bearing on the outside of the other cap, G. Springs, M, are as
shown by preference applied round the long bolt, H, in a manner to keep the
bearing caps, G, close to the head, K, and nut, L, respectively, and thereby prevent
rattling of the parts, when a slight slackness is produced by wear.
The long
bolt, H, whilst securing the bearing caps, G, contributes to the strength of the rod.
Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is
Constructing, combining, and arranging the parts of connecting rods so as to
have the same adjusting action for the caps of both end bearings, and otherwise
substantially as hereinbefore described and as shown in the accompanying drawings.
Dated this Eighth day of December 1891.
