The conical member may be'kept in position laterally by means of a removable cover secured to the casing a by studs and nuts and shaped on its inner surface to correspond to the member g. rlhe cover may be provided with a set screw to bear tightly against the conical member. By removing the cover both the latter and the nozzle can be easily removed from position. In Figs. 1, and' 2, we have shown the cover 7a as part of the cone g, the combined unit being secured to the casing a by studs and nuts m. The studs pass through slots n in the' cover to enable a jack screw 0 carried by the upper flange p ofthe casingI a to jam themember g' down on to the vnozzle Z9 before'the cover kis tightened up.
By the arrangements previously described sire to secure by Letters Patent is Ink an injector, a casingprovidedV with two inlets and one outlet and having an Internal shoulder and a lateral opening between the `shoulder and'one inlet, a nozz'levformed-in vtwo sections arranged end to end and supported in the casing between the said inlet and the outlet, the outlet section being held against the said shoulder by the inlet seotion, and the inlet section being removable through the saidlateral openingv inthe casing and provided with a flange which closes the lateral opening, and means which secure the said flange to the casing. y
In testimony whereof we have hereunto set our hands.
