We, FREDERICK ALBERT MORETON, of 13, Station Road, Handsworth, in the
County of Stafford, Engine Fitter, and FRANK HENRY MORETON, of 167, Icknield
Street, in the City of Birmingham, Tobacconist, do hereby declare the nature
of this invention to be as follows:
This invention relates to improvements in means for connecting the piston
rods of engines or pumps to their crossheads, and also may be applied to other
like. connections, and has for its object the providing of a more simple and
effective connection, whereby we are enabled to dispense with the usual slotting
and the use of cotter pins &c.
We carry out this our invention somewhat as follows:-The piston rod, at
the end which is to be connected to the crosshead, is tapered inwards for a short
distance. We further provide a collar or bush, tapered both internally and
externally, its internal diameter corresponding to the beforementioned tapered
end of the piston rod. This collar is further split into two or more parts as
desired in order that it may be passed onto the tapered end of the piston rod.
Further we provide a connecting plate having in its centre a taper hole which
corresponds. to the external diameter of the split collar; also this connecting plate
is provided with a suitable number of holes by which it can be bolted or other-
wise secured to the crosshead.
The application of our invention is as follows:-The connecting plate is first
passed onto the piston rod beyond the tapered part, the split collar is then
placed in position on the tapered end of the piston rod, and the connecting plate
is then drawn back onto the split collar, and secured to the crosshead by means
of, bolts or other suitable means. The piston rod end abuts against the cross-
head and it will thus be seen that the act of bolting up the connecting plate to
the crosshead tends to draw the said plate and the tapered split collar up the
tapered end of the piston rod, and thereby a simple yet very effective connection
is made.
In some cases we may use a split collar having only its internal diameter
tapered, its external diameter being parallel; in this case we should form a
shoulder thereon which may fit into a recessed part in the connecting plate;
also the hole in the connecting plate would be parallel. In this case by reason.
of the shoulder on the split collar engaging with the connecting plate, the said
collar would be drawn up the tapered end of the piston rod, and the connection
thus made as before.

page_text: It will be seen that with but slight modification, this our invention may be
applied to the connections for piston rods to pistons, or for coupling lengths of
shafting, or other like purposes.

Improvements in Connections for Piston Rods and Crossheads and the
like purposes.
FREDERICK ALBERT MORETON, of 13, Station Road, Handsworth, in the
County of Stafford, Engine Fitter, and FRANK HENRY MORETON, of 167, Icknield
Street, Birmingham, in the County of Warwick, Wholesale Tobacconist, 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 follow-
ing statement:
This invention relates to improvements in the means for connecting the piston
rods of engines or pumps to their crossheads, and also may be applied to other
like connections, and has for its object the providing of a more simple and
effective connection, whereby we are enabled to dispense with the usual slotting
and the use of cotter pins &c.
We will at once proceed to more fully describe this our invention by the aid
of the accompanying sheet of drawings, upon which are figures and numbers
of reference like numbers referring throughout to the same thing or part.
Fig. 1, is a side elevation partly in section of this our invention as applied
to the connection of a piston rod to crosshead, and Fig. 2, is a front view of
same.
Fig. 8, is a detail view of the piston rod, showing tapered part.
Fig. 4, is a front view of the tapered split collar or bush, and Fig. 5, is a side
sectional view of same.
:
Fig. 6, is a front view of the connecting plate, and Fig. 7, is a side sectional
view of same.
Fig. 8, shows a modified form of tapered split collar and Fig. 9, is a side
sectional view of same.
Fig. 10, shows a front view of modified form of connecting plate and Fig. 11,
is a side sectional view of same.
Fig. 12, shows the application of this our invention to the connecting of piston
rods to their pistons.
The piston rod 15, at the end of which is to be connected the crosshead 16, is
tapered inwards at 17, for a short distance. We further provide a collar or bush 18,
tapered both internally and externally, its internal diameter corresponding to
the beforementioned tapered end 17 of the piston rod 15.
This collar 18, is
further split into two or more parts as desired (shown only in two parts) in order
that it may be passed onto the tapered end 17 of the piston rod.
Further we
provide a connecting plate 19, having in its centre a taper hole 20, which corres-
ponds to the external diameter of the split collar 18; also this connecting plate 19
is provided with a suitable number of holes 21, 21, by which it can be secured
by means of bolts 22, 22; to the crosshead 16, or other suitable means for con-
nection may be employed.
The application of this our invention is as follows:--The connecting plate 19,
is first passed on to the piston rod 15, beyond the tapered part 17, the split

page_text: collar 18 is then placed in position on the tapered end 17, of the piston rod 15,
and the connecting plate 19 is then drawn back onto the split collar 18, and
secured to the crosshead 16, by means of bolts 22. The piston rod end abuts
against the crosshead at the point 23, and it will thus be seen that the act of
bolting up the connecting plate 19 to the crosshead 16, tends to draw the said
plate and the tapered split collar up the tapered end of the piston rod, and
thereby a simple yet very effective connection is made.
If desired we may use a modified form of split collar as shown in Figs. S and 9,
this collar 18, having only its internal diameter tapered, its external diameter
being parallel; in this case we form a shoulder 24 thereon, which said shoulder
engages with the recess 25, in the connecting plate 19", see Figs. 10 and 11. By
these means the split collar 18", can be drawn up the tapered end of the piston
rod, and the connection thus be made similarly as before described.
In Fig. 12, we have shown the application of this our invention to the con-
necting of a piston rod to the piston; in this case 15", is the piston rod, 19b, the
connecting plate, and 26, the piston, the whole being connected together similarly
as before.
Having now particularly described and ascertained the nature of this our
invention, and the manner in which the same is to be performed, we declare
that what we claim is;.
-
1. In the means for connecting piston rods to crossheads, and the like con-
nections, the combination with the taper ended piston rod, of the tapered split
collar 18, and connection plate 19, or 19b, substantially as set forth and shown,
in Figs. 1 to 7 and in Fig. 12.
2. In the means for connecting piston rods to crossheads and the like con-
nections, the combination with the taper ended piston rod, of the tapered split
collar 18, and plate 19", substantially as set forth and shown, in Figs. 8 to 11.
