IMPROVEMENT INSTEERVING-GEAR FOR VESSELS.
Specification forming part of Letters Patent No. 197,871, dated December 4, 1877; application filedA Apmlso, 1877.' f
To all whom it may conce/rn:
Be it known that I, JOSEPH I). MAN'roN, of the city and county of Providence, in the State of Rhode Island, have invented certain new and useful Improvements in Steam-Steering Gear 5 and I do hereby declare that the following specification, taken in connection with the drawings furnished and forming a part of the same, is a clear, true, and complete description thereof.
My said improvements are applicable, in whole or in part, to steam-steering apparatus as heretofore constructed.
Briefly stated, the object thereof is to provide for the steering of a vessel either by hand or by the employment of steam-power, and also to provide for the relief of the loperative mechanism from the injurious elfect of shocks incident to the strokes of waves against the rudder; and to these ends my invention cony sists, rst, in the combination of the rudderpost, having a circular plate mounted thereon, of an annular worm-gear surrounding said plate, and connected therewith by a detachable key or keys, and right and left handscrews operated by suitable steam -driven gearing, whereby the rudder may be lreadily connected or disconnected from the steam mechanism by the insertion or removal of a key or keys.
To more particularly describe my invention7 I will refer to the accompanying drawings, in which- Figure l represents, in plan view, a complete steam-steerin g apparatus embodying the several features of my invention. Fig. 2'represents the same, partly in end vie'w and partly in central vertical section, on a line with the center of the rudder-post. Fig. 3 represents, in section,'a portion of one of the screws, its shaft, and cushion. l
The steam apparatus here shown consists of two double-acting cylinders, A, which are coupled, in a manner Well known, to a crankshaft, B. 'The steam-pipe, which communieates with both cylinders, is provided'with a valve at C, constructed in a manner also well known, so as to control the induction and eduction of steam to and from both cylinders, for stopping, starting, and reversing the engine by a simple movement of the valve-rod, which is manipulated by the wheel-man in steering the vessel.
From the various well-known styles of valvegear suited to locomotive and similar service,
many selections of valve-gear may be made for attaining good results in this connection.
The rudder-post is shown at D, provided with a tiller, D', which may be directly employed for steering by hand, or connected with the well-known tiller ropes and wheel. The
rudder-post is provided with a circular plate,
Y with vertical square-sided slots or scores, as
at a, which serve in each instance as one-half of a key-seat.
F denotes an annular worm-gear, which is concentrically mounted on the plate E. The eye of this worm-gear'is key-slotted, to correspond with the key-slots in the plate, already described, so that when a key, as at b, is inserted, the gear and the plate will be rotatively connected.
G denotes in each instance 011e of two screws which engage with the worm-gear F at opposite sides thereof. One screw has a right and the other a left hand thread. These screws are revolved by gears c, which mesh with a smaller gear, at d, on the crank-shaft.
As thus constructed, it will be seen that the rudder-post will be firmly held in any desired position, while the engines are not in motion, by the oppositely located screws and the worm-gear, and also that, on removing the key or keys I), the rudder may be operated by hand wholly independent ofthe steamgeaiin g..
Each of the screws is so mounted on its shaft c that it is rotatively connected therewith, but free to move longitudinally thereon. Each shaft e is provided with two collars, f, which are keyed or otherwise secured to the shaft, one-near each of its journal-boxes. Between each collar and the adjacent end'of the screw is an elastic cushion or buffer. In this instance it is shown to be composed ofI elastic material, preferably of vulcanized rubber, although other forms of spring may be employed,
as heretofore, for relieving the screws and gearing from shook incident to the striking of the rudder by Waves.
The rubber spring is shown at g, and it is embraced Within tWo anged collars, h, vso mounted on the shaft as to be longitudinally free thereon Within the space between the fixed collar j' and the end of the screw.
Each collar h may be provided with short doWels, as at t', which occupyholes in the rubber spring, all of Which is shown in detail in Fig'. 3.
` Having thus described my invention, I claiml as'new and desire to secure by Letters Patent- The combination, with a rudder-post provided with a circular plate, of an annular Wormgear surrounding said plate, and connected therewith by a detachable key or keys, and screws which mesh with the Worm-gear, and are operated by suitable steam-driven gearing, substantially as described.
