We RICHARD MORRIS of Beechfield Doncaster in the County of York Engineer
and JAMES WOOD of West Stockwith in the County of Nottingham Engineer do
hereby declare the nature of this Invention to be as follows:-
The object of this Invention is to provide a simple and efficient clutch or coupling
which need have no keys or screws necessitating cutting the shafting and in which no
projecting parts such as bolt heads and nuts are needed. The clutch or coupling is
also readily detachable and so also is the shafting to which it is applied and the clutch
or coupling will accommodate itself to inequalities in the bearings of the shafts.
According to this Invention one part of the clutch secured to the one end of the
shafting to be coupled is provided with a rim with slots or openings therein for the
reception of engaging pieces or bolts on the part of the clutch carried by the other
part of the shafting to be coupled. These bolts are provided with pins which engage
in cam or eccentric grooves in a plate or disc mounted so as to turn on the last named
part of the shafting. This disc is enclosed in the part of the clutch or coupling
mounted on this part of the shafting the bolts projecting therefrom so as to be in line
with the openings for them in the other part of the clutch. The disc is capable of
having a partial rotation given to it which may be effected by a pinion mounted in the
interior of the coupling or clutch and engaging with a toothed segment on the disc.
This pinion may have the part which is mounted in the clutch body with a squared
recess in it for the reception of the key for turning it. When this pinion is turned
the disc is also turned so that its eccentric slots act on the pins of the bolts and the
bolts are moved outwards to engage with the slots or openings in other part of the
clutch and the shafting is thus coupled. By rotation in the other direction the bolts
are withdrawn and the shafting is uncoupled. The parts of the clutch are mounted

page_text: on and secured to the ends of the shafting by forming the holes in their bosses conical
and placing in these similarly shaped bush pieces which are forced inwards by a cap
piece screwing over the boss of the coupling and forcing the conical bush
pieces tightly in place to fix the part of the coupling or clutch to the shafting. The
screwed caps are preferably formed with holes in their periphery for the insertion of
rods for turning them. The end of the shaft carrying the part of the clutch with the
holts may have a small portion of its end received in a bearing in the other part of
the clutch on the other shaft end.

Improvements in Clutches and Couplings for Shafting.
We RICHARD MORRIS of Beechfield Doncaster in the County of York Engineer
and JAMES WOOD of West Stockwith in the County of Nottingham Engineer 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:
The object of this Invention is to provide a simple and efficient clutch or coupling
which need have no keys or screws necessitating cutting the shafting and in which no
projecting parts such as bolt heads and nuts are needed. The clutch or coupling is
also readily detachable and so also is the shafting to which it is applied and the clutch
or coupling will accommodate itself to inequalities in the bearings of the shafts.
Figure 1 of the accompanying drawings represents a longitudinal section and
Figure 2 represents a face view of the interior of the part B of a clutch or coupling
made according to this invention. The part A of the clutch or coupling secured to
the one end of the shafting to be coupled is provided with a rim a with slots or
openings a² therein (see the view of a part of the rim in Figure 3) for the reception
of engaging pieces or bolts D on the part B of the clutch carried by the end of the
other shaft E to be coupled. These bolts D are provided with pins d which engage in
cam or eccentric grooves fin a plate or disc F mounted so as turn on the last named
end E of the shafting. This plate or disc F is enclosed in the part of the clutch or
coupling B the bolts D projecting therefrom so as to be in line with the openings a²
for them in the other part A of the clutch or coupling. The bolts D are guided by
lugs F2 on the part B. The disc F is capable of having a partial rotation given to it
which may be effected by a pinion G mounted in the interior of the coupling or
clutch and engaging with a toothed segment H fixed or formed on the disc F. This
pinion G may have the part which is mounted in the clutch body with a squared
recess in it for the reception of the key for turning it. When this pinion G is
turned the disc F is also turned so that its eccentric slots fact on the pins d of the
bolts D and the said bolts are moved outwards to engage in the openings a² in the
part of the clutch A and the shafts C and E are thus coupled. By rotating the
pinion G in the other direction the bolts D are withdrawn and the shafts aro
uncoupled.
Instead of the recesses a² in the part A for the reception of the bolts D the said
part A may be provided with spring detents d² as shown in Figure 4 there being one
of the said detents for each bolt which bolts may be projected by means of the wheel
and segment G and H as before described, so that when as the shafts rotate the bolts
come into contact with the inner sides of the detents d the said detents will yield and
enter the recesses 3 but when the bolts pass the ends of the said detent and come
against the stops the detents will be again caused to project by the action of the
springs and thereby lock or couple the two shafts. Any desired number of bolts D
may be employed. The parts A and B of the clutch or coupling are mounted on and

page_text: secured to the ends of the shafting C and E by forming the holes in their bosses conical
and placing in these similarly shaped bush pieces i which are forced inwards by a cap
piece J screwing over the bosses of the parts of the clutch or coupling and forcing
the conical bush pieces i tightly in place to fix each part of the clutch or coupling to
the shafting. The screw caps J are preferably formed with holes in their periphery
for the insertion of rods for turning them. The end of the shaft E carrying the part
of the clutch or coupling B may have a small portion of its end received in a bearing
in the other part A of the clutch or coupling as shown at k.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is —
1. The arrangement and combination of parts constituting the clutch or coupling
substantially as hereinbefore described and illustrated in Figures 1, 2 and 3 of the
accompanying drawings and the modified arrangement Figure 4.
2. In clutches or couplings parts attached to the respective ends of the shafts to
be coupled the one part having therein bolts which can be projected outwards to
engage with the other part substantially as hereinbefore described.
3. In clutches or couplings the means for securing the parts of the clutch or
coupling to the shaft consisting of the conical pieces i and caps J substantially as
hereinbefore described.
4. In clutches or couplings for shafts the provision of a bearing in the part of the
clutch or coupling fixed to one shaft end in which bearing is received the end of the
other shaft as hereinbefore described and shown at k in the accompanying drawings.
