devices, of -a cylindrical split bushing, which, by forci ble contraction in size, tightly embraces the ends of the shafts to be coupled.
In the accompanying drawings- Figure 1 is a perspective view of the several pieces of the coupling detached.
' Figure 2 is a cross-section of the coupling together, and in place on the sliafting.
.A A are the'ends of the shafts to be coupled, which have key-seats cnt, as shown, for thc reception of' the key B.
I prefer to use the double-draught key'B for this connection, as shown in the accompanying drawings, andalso shown in my Letters Patent for s haft-coup lng, December 29, 1868.
The bushing C is designed to fit the ends of the shafts A A', extending equally over th'e ends from the point where the shafts meet.
The interior of the bushing isA slightly key-seated at c to fit the top of the key Bjand is attened ontop at b lto form a seat for key D. l v
The bushing C is cnt or split at d, to allow of it i *MP- being contracted in size, the out being of suliicient width to permit the necessary ccntraction.
The sleeve E fits snugly over the split bushing C, and is key-seated to receive the key D.
are in place, is driven tightly in between thc outer sleeve E and inner-.bushing C, and being taper,l as shown, serves to contract the size of the bushing C,
it is impossible for the shafts to be 'drawn from the coupling endwise.
I am 'aware thatcou'plings have been used in which the inner sleeve'or bushing is'split or cut, and made to contract in size, by being forced endwise within an outer sleeve, the exterior of the inner'bushing and the interior .of the outer sleeve being respectively turned and bored tapering and made to fit.
