i @citen gisten stmt @ffice IMPROVED STEERING APPARATUS.
Be it known that I, REUBE'N SPARKS, of the city of Buffalo, county of Erie, and State of New York, have` invented a new and improved Steering Apparatus; and I do hereby declare that the following is a full and exact` description thereof, reference being had to the accompanying drawings, making a part of this specication, in which- Figure I is a-front elevation; and
Figure II is a plan view of my improvement. K
The nature of this invention consists in the combination and arrangement (if a. series of spur-wheels and pinions, with-a vertical shaft carrying the hand-wheel, and a horizontal chain-Wheel or drum, to which the rudder chains are connected; the said gearing being constructed in such relative proportions that a considerably less number of revolutions of the hand-wheel is suiiicientto move the tiller of the rudder through the requisite distance without a material increase of power or exertion on the part of the steersman.
Letters of like name and kind refer to like parts in each o f the figures. p p
A A represent a portion of the framework of vessel, which support `the steering apparatus.` B represents a vertical shaft, revolving in journal bearings, b'. C represents the hand-wheel for operatingthe apparatus;
it is keyed to the top of the shaft, B, and when set in motion imparts its horizontally rotatory movement Vto the shaft, B." Apinion, D, is keyed to the lower end of the shaft, B, which gears withspur-wheels, E, upon countershafts, E'. Journal bearings, e, are formed on the bridge-tree, A', which constitutes a part of the framework. The counter-shafts, E', carry upon their lower ends pinions, F, which gear with the spu-wheel, G, attached to the horizontal chain-wheel or drum,` H. This spur-wheel G, when an external one, is located between the pnions,
i F, as shown in the drawings. It may also be made an internal spur-wheel, and in that case the pinions, F,
revolve upon its inner side. It will be observed that one spur-wheel E, one pinion F, and one counter-shaft E are sufficient to transmit motion from the shaft, B, to the chain-wheel, H, but in order to prevent undue strain upon the shafts, I prefer to employ two sets, one'npon each side of the shaft, B, as shown in the drawings.` The shaft to which both the spur-wheel, G, and chain-wheel, H, are connected, is b elow and -in line with the main shaft, B, and has bearings in both the bridge-tree, A', and the de ck of the vessel. The chain-wheel, H, has two grooves cut in its outer rim, or edge, one above the other. A chain, I I', lies in each groove, and one end thereof is connected to the rim of the wheel as shown at jj the other end of each chain is attached to a chain-wheel,
', in a similar manner. This chain-wheel, H', is made fast to the stem of the rudder, and is' of the same general construction as the chainwhecl, H. The rudder isshown at K. The tiller of the rudder is represented chains,I I', over snatch-blocks and attach them to the end of the tiller as shown in red lines, in Fig. II, and in that case the chainwheel, H', is not required. An elastic link is interposed in the chains as shown at L, Fig. II, for the purpose of keeping the chains from breaking in case of sudden jars to the rudder in high seas, or when the movement of the chains should be suddenlyarrested by obstructions upon the deck of the vessel,
What I claim as my invention, and desire to secure by Letters Patent, is A l Y K The arrangement of the vertical shaft B, having a pinion D on the lower end thereof, `with the pinions I1'- and F, and spur-wheel G, connected with the drum H, and chain I I', connecting with the drum H, and wheel H', substantially as described.
at k', andas a modification of my improvement, and especially when old` vessels are to be provided with this improved steering apparatus, it may in some casesbedesirable, and at the same timeA less expensive, to pass the
