- this part of my invention consists in coinbiniug the location of the shaft and propeller with the rudder made with a slot commencing at the outer edge,that it (the rudder) may have the requisite play; and myinvention also consists in supporting the propeller abaft the vessel by a sliding or swinging frame having a box iu which a journal of the hub turns, when this is combined with the shaft made in two parts, one sliding within the other, and so connected and provided with the necessary inechanical means that the sliding part of the shaft may be inserted and withdrawn f
- Thepropeller the hub ol' which is elongated and formed into a journal, is supported abaft the vessel by a frame of wrought-iron or composition metal, the lower end of which is provided with a bearing made to receive the said journal.
- the frame is made either to slide up and down on a suitable guide, the upper part of which guide is attached to the ships counter and the lower part to the stern-post, or it is made to swing on an axis or spindle attached to the stern-post just above the water-line, and it is raised and lowered by a chain worked by a windlass.
- the propeller-shaft passes through the run by the side of the stern-post, a bearing being bolted to the sternpost to support the shaft.
- a slot is cut in the latter for about half its width, beginning at its outer edge.
- This slot permits the rudder to turn as far as an angle of forty-tive degrees with the centerline of the vessel.
- the propeller-shaft is composed of two parts, the one sliding within the other a. distance equal to the length of the hub of the propeller, the outer part being the sliding one, and the motion requisite to withdraw it from the hub ofthe propeller being given to it by a rack and pinion. Both ends of this sliding part of iluI shalt are made either square or six-sided or round und i'eathertal, the outer end being malle taper, Corresponding to a taper hole in the hub ol'tlie propeller. and the inner end being parallel and eorrespondingto aparallel hole in the other part ol' the shat't. The water is prevented from entering around the shaft where it goes through the run by a -slul'lingbov.

- parts ol' mv invention may be advantageously employed without otherswas, torinstanee, the loeatiou ol ⁇ the sbutt and propeller,in eonnee ⁇ tion with the siotting of the rudder, may be employed to advantage without the use ofthe mode of disconnecting the propeller from the shalt and elevating it, and so this latter part of my invention may be employed without the former; but by union ofthe whole the best results will be at tained.
