Improved Couplings for or Means of Coupling Shafts, Rods,
and the like.
I, CHARLES HOLLOWAY REED, of Trimdon Iron Works, Sunderland, in the County
of Durham, Iron Manufacturer, do hereby declare the nature of the said Invention
to be as follows :-
This invention relates to improved couplings for or means of coupling shafts, rods
and the like, the Invention comprising certain improvements in or applicable to the
formation of the end parts of shafts, and the corresponding formation of the coupling
parts in the improved manner hereinafter described.
In accordance with the present improvements (which are applicable to rods, tie-
bolts, bars, shafts or analogous parts constructed of iron, steel or other material, and
whether formed with or without swells, collars or enlarged parts at their meeting
ends) the end parts of the shafts are forined with any required number of peripheral
recesses parallel with the axis of the shaft, and which may be made of any required
width, depth and length, and of any suitable formation in cross section, being pre-
ferably made of a semi-cylindrical or other suitable formation in which the widest
part of the recess is outwards coincident with or towards the periphery of the shaft ;
the end parts of the shafts are also formed with one or more encircling or partly
encircling grooves or grooved parts, which, if continuous around the shaft, preferably
intersect such peripheral recesses formed therein. The couplings may be made of
cast iron, steel or of other suitable metal or material, and in one or more parts, and
are formed with internally projecting parts corresponding in disposition and shape to
those of the said encircling or partly encircling grooves or grooved parts formed in
the shaft ends and adapted for preventing endway separation of the coupled shafts,
and also with other internally projecting parts corresponding in disposition and shape
to those of the said peripheral recesses in the shaft ends and adapted for causing
the conected shafts and couplings to rotate together. Or the said couplings may be
formed with recesses or grooved parts opposite the said peripheral recesses in the
shaft, and such opposite recesses may be adapted with separate filling up parts of
corresponding formation in such a manner as to attain the said result of causing the

page_text: connected shafts and couplings to rotate together. The said couplings are preferably
made in segmental sections or parts as they can then be the more readily applied to
the shafts, and such sections or parts may be formed with or without flanges and may
be united together by bolts, rings, or other appropriate means. The couplings or the
segments thereof may extend as regards their width from end to end of the said
peripheral recesses of the connected shafts or for such other extent as may be
desired.

Improved Couplings for or Means of Coupling Shafts, Rods,
and the like.
I, CHARLES HOLLOWAY REED, of Trimdon Ironworks, Sunderland, in the County
of Durham, Iron Manufacturer, do hereby declare the nature of my said Invention,
and in what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement :-
This Invention relates to improved couplings for or means of coupling "shafts,"
(which term is intended to comprehend tie-rods, bars, bolts, shafts or analogous parts
constructed of iron, steel, or other material, and whether formed with or without
swells, collars, or enlarged parts at their meeting ends,) and the Invention comprises
certain improvements in or applicable to the formation of the end parts of the shafts,
and the corresponding formation of the coupling parts thereof in the improved
manner hereinafter described.
Various modifications of carrying out the Invention are illustrated on the
accompanying drawings, and will be hereinafter more particularly referred to.
On the accompanying drawings; Fig. 1, represents a sectional elevation through
the line, a,b, Fig. 2, of one modification of the Invention; and Figs. 2, and, 3,
represent transverse sections of Fig. 1. respectively through the lines, c, d, e,—f.
Figs. 4, to, 6, respectively represent similar views of another modification, the
sections being respectively through the lines, g, h, i,—j, k,—l.
Figs. 7, to, 9, respectively represent similar
sections being respectively through the lines, m,
views of another modification, the
n, o,—P, I,―r.

page_text: Figs. 10, and, 11, respectively represent a sectional elevation, and a transverse
section, respectively through the lines, s, t, u,v.
Any of the modifications herein described may be applied to shafts formed with
or without enlarged ends.
In accordance with the modification illustrated in Figs. 1, to, 3, the end adjacent
parts of the shafts, 1, are formed with any required number of coincident peripheral
recesses 2, parallel with the axis of the shafts, and such recesses may be made of any
required width, depth, and length, and of any suitable formation in cross section,
being preferably made of a semi-cylindrical or other suitable formation in which the
widest part of the recess is outwards coincident with or towards the periphery of the
shaft. The end parts of the shafts are also each formed with one or more peripheral
grooves or grooved parts, 3, encircling or partly encircling the shaft ends, and
preferably but not necessarily intersecting with the said recesses, 2.
The shaft ends are coupled or connected in such a manner as to cause them to rotate
together and to prevent their endway separation, by sectional or segmental couplings, 4,
which may be made of iron, steel, or other suitable metal or material, and are formed
with internally projecting parts, 5, corresponding in disposition and shape with those
of the said peripheral recesses, 2, formed in the shaft ends, and adapted for causing
the connected shafts and couplings to rotate together, and also with other internally
projecting parts, 6, corresponding in disposition and shape with those of the said
encircling peripheral grooves or grooved parts, 3, in the shaft ends, and adapted for
preventing endway separation of the coupled shafts.
In the modification illustrated in Figs. 4, to, 6, the shaft ends, 1, and segmental
couplings, 4, are reversely formed, that is, the shaft ends are formed with external
projections, 5, 6, and the segmental couplings with internal recesses or grooves, 2, 3,
respectively corresponding in disposition and shape with those of the said
projections, 5, 6.
In the modification illustrated in Figs. 7, to, 9, the shaft ends and segmental
couplings are respectively formed with recesses or grooves, 2, 3, at opposite parts,
and the said opposite recesses, 2, are adapted with separate or removable filling up
pieces, 5, and the said opposite encircling grooves, 3, are adapted with separate or
removable filling up segments, 6.
In any of such modifications the shaft ends may be centred relatively to each other
by a removable spigot piece, 12, fitting into corresponding holes formed centrally in
the adjacent ends of the shafts; or there may be adapted, between the meeting ends of
the shafts, a keyway, 7, and key, 8, which latter may be of any suitable section, and the
ends of which may project and enter corresponding recesses, 9, made in the adjacent
parts of the couplings as in the modification represented in Figs. 10, and, 11, which
otherwise (excepting the spigot piece, 12,) agrees with the modification illustrated in
Figs. 1, to, 3.
In other modifications, the projecting parts or filling up pieces, 5, 6, may be replaced
by fixed or removable studs or like projecting parts and the improvements herein
described may be variously combined.
In all modifications, the improved couplings are made in segmental sections or
interchangeable parts, of any required number, in order to allow of them being readily
applied to the shafts, and such sections or parts are preferably formed with flanged
parts, 10, which may be secured together by bolts, 11, or the said sectional couplings
may be held together by surrounding rings formed entire or in parts screwed or
otherwise united together, or by other appropriate means. The couplings may extend
as regards their width from end to end of the said recesses, 2, of the connected shafts,
or for such greater or less extent as may be desired.
Having now particularly described and ascertained the nature of my said Invention,
and in what manner the same is to be performed, I declare that what I claim is ;-
1. The construction of the end parts of shafts with peripheral recesses or projecting
parts parallel with the axis of the shafts, in combination with peripheral grooves or

page_text: grooved parts or projecting parts encircling or partly encircling the shaft ends,
substantially as and for the respective purposes hereinbefore described.
2. The construction of couplings adapted for use with the end parts of shafts thus
constructed or formed, with inner projecting or grooved parts corresponding in disposi-
tion and shape with those of the said recessed or projecting parts of the shaft ends,
and in sectional or segmental parts or interchangeable parts adapted for connection
together, substantially as and for the respective purposes hereinbefore described.
3. The combination of shafts and couplings respectively and correspondingly adapted
and formed, substantially as herein before described.
4. The modification hereinbefore described, in which the shaft ends and segmental
couplings are respectively formed with opposite recesses or grooves which are adapted
with separate or removable filling up pieces or segments, substantially as hereinbefore
described.
5. The application between shaft ends, formed, adapted and coupled in accordance
with the present improvements, of a key-way and key, or the equivalents thereof,
substantially as hereinbefore described.
6. The construction of the shaft ends, or of the said couplings, with, or the application
thereto of, fixed or removable studs or like projecting parts, in lieu of the said
projecting parts, 5, 6, substantially as hereinbefore referred to.
7. The application of the improvements hereinbefore described or referred to in any
suitable combination or combinations.
