PADDLE-WHEEL WITH FEATHERING-BLADES.

SPECIFICATION forming part of Letters Patent No. 641,289, dated January 16, 1900.

Application filed J une 23, 1899.

To all whom t may concern:

Be it known that I, REINHOLD HEERE, teacher, a subject of the King of Prussia, German Emperor, residing at l0 Kleine Rosenthalerstrasse, Berlin, Germany, have invented new and useful Improvements in Paddle- Wheels with Feathering'Vanes or Blad es, of which the following is a specication.

The present invention relates to an improved paddle-wheel with feathering vanes or blades, which by virtue of its special construction is applicable both for high-sea navigation as well as for inland navigation.

The improved paddle-wheel which forms the subject of the present application and the blades of which are actuated upon at both ends from the engine on the vessel directly is successfully applicable for high-sea navigation as well as for inland navigation in view of the fact that in the first instance the motive power by the agency of a main shaft, which, if necessary, may be driven at both ends, and by the agency of two cross-'shaped frames, one of which is rigidly mounted on said main shaft, is uniformly supplied to both ends of the paddle-wheel blades, While sim ultaneously the second cross shaped frame causes the variation in the position of the blades, so that the latter assumes the required angle in regard to the water or their feathering, respectively, by being suitably connected to said cross-shaped frame, which supports the blades at either end thereof. In view of these arrangements the blades are prevented from jamming in their bearings whatever position the vessel may be in, lateral pressure of the waves likewise not demanding any consideraticn, as it cannot exercise any detrimental effect on the action of the blades, so that these latter may be constructed and employed of any desired suitable width. A paddle-wheel with feathering-blades constructed in such a manner is applicable for the largestsized vessels. In addition the amount of motive power required is considerably reduced in comparison to the hitherto-known constructions of paddle-wheels and of screw-propellers.

I will now proceed to describe my invention more fully, reference being had tothe accompanying drawings, in which- `Figure l shows a side elevation of my improved paddle-wheel. Fig. 2 is a section Serial No. 721,664. (No model.)

through the paddle-wheel in the direction of the longitudinal axis of same on line A A of Fig. 1. Fig. 3 illustrates a perspective view of one of the blades of the paddle-wheel. Fig. 4 is a diagrammatic view illustrating the position of the paddlewheel in regard to the stern of the vessel.

On the shaft a. are rigidly mounted at either end two cross-shaped structures o, the oppo-v site arms of which are connected by staying; rods d, so that they form a strong frame; The shaft a may, if necessary, be provided with cranks h at either end, arranged at an angle of ninety degrees in regard to each other. The shaft penetrates outside the cross-shaped structures c two eccentrics e, which are stationary, and thus serve as bearings for the shaft. On the circumference f of these two eccentrics e are rotatably mounted two likewise cross-shaped structures g. These structures are situated adjacent to the structures c and firmly connected to each other by means of staying-'rods c'. The driving-frame c imparts motion to the frame g by means of suitable couplings-"e-such, for instance, as cranks h, which are pivoted on the one hand to one of the arms of the frame c and on the other hand to the adjacent arm of the frame g. The staying-rods t' of the frame g pass through slots in projections on the back of the blades or vanes m, or through slots in the body of vanes, respectively.

Rollers 7o serve for attaining an easy movement in the slots. Each two opposite arms of the driving-frame c, which is firmly mounted on the shaft a., are rotatably connected at their extremities by means of bolt n to one of the blades m, thus supporting them.

The motion imparted tothe shaft a .from the source of motive power, if necessary by the auxiliary of the cranks b, will rotate the frame c, constituted as above described. Simultaneously, in view of the connection between the frame c and the frame g, the latter will be rotated around the eccentrics e, and by virtue of the movability of the stayingrods t' of the frame g in the slots in the vanes `or blades m these latter will feather or be caused to vary their positions in regard to the two frames in a regular and predetermined manner, respectively, as required.

In view of the novel features of construc- IOO vshaped frame c rigidly mounted on the shaft i .a., a second cross-shaped frame g for regulating the feathering of the vanes being movably mounted on stationary eccentrics and rotated by the rst frame c by being pivotally connected to the latter by means of suitable couplings, substantially as and for the purposes set forth.

In testimony whereof Iy have hereunto set my hand in presence of tWo subscribing Witmesses.

REINHOLD HEERE.
