IMPROVEMENT IN FEATHERING PADDLE-WHEELYS.

Specification forming part of Letters Patent No. 15,149, dated June 17, 1856.,

To all whom it may concern:

Be it known that I, JOSEPH G. SHANDs, of the city and county of St. Louis, and State of Missouri, have invented a new and Improved Paddle-Wheel for the Propulsion of Vessels;

. and I do hereby declare that the following is a full and eXact description thereof, reference being had tothe accompanying drawings, making a part of this specification.

Figure l in said drawings is a side View of my improved paddle-wheel; Fig. 2, a face view thereof; Fig. 8, a section in the line y y of Fig. 2; Fig. 4, a section of one of the eccentric rings O and one of the steadying-wheels D, showing their relative position with each other and with the main shaft A; and Fig. 5 is a side View of one of the vertically-acting bucketarms h detached from the wheel.

Similar-lettersindicate like parts in all the gures.

My improved paddle-wheel is constructed in such a manner that the buckets z' 1.' of said wheel are retained in a vertical position during their entire revolution, and by such an arrangement of parts as guards said buckets at all points against liability to injury from any of the ordinary shocks or concussions which paddle-wheels are exposed to.

A is the Wheel-shaft.

B B are the rims of the wheel, which are connected to its shaft in the ordinary manner by means of a suitable number of arms radiating from hubs placed thereon. The rims B B of the paddle-wheel are connected to each other by means of a series of bucketshafts g g, Whose outer extremities project beyond the outer sides of the rims and whose journals are received into journal-boxes secured to said rims. The buckets may be secured to their shafts g g in the manner represented in the drawings or by any other suitable method. Rings U C, that are a little larger in diameter than the rims B B of the paddle -wheel, are placed outside the said wheel-rims and a sufficient distance vertically above them to enable said rings to be connected to the projecting ends of the bucket- Shafts g g by means of the arms h h, which are rigidly'secured to the said bucket-shafts and which are jointed to the rings O'O by means of properly-secured pivot-bolts. The bucket-arms 'h h are secured to the bucketshafts g g in such positions, respectively, as to .cause them to be all parallel with each other and parallel with the sides of the buckets z' ,and the said bucket-arms are of such a length as to cause them to all stand in vertical positions when the rings C C are supported in such a manner as to bring their axes vertically above the axis of the paddlewheel. To relieve the bucket-arms h h from the severe shocks caused by the rings O C being brought in violent contact with ice, logs, or other obstructions, or from shocks caused by the sudden stoppage of the vessel or other y cause', I place Within each ring O a steadying grooved wheel D, secured to the wheel-shaft A and acting on the inner periphery of said rings. L also place two smaller grooved wheels E E on suitable arbors lF F in such positions as to act on the outer peripheries of said rings opposite their axes. The said grooved Wheels E E rotate freely on their arbors F F, and they are allowed to have a limited lateral movement on said arbors controlled by the odsets or shoulders lo k, and the springsjj interposed between said offsets or shoulders and the said grooved wheels, which arrangement enables the grooved wheels E E to adaptthemselves to all the needful lateral oscillations of the said rings and yet enables said grooved wheels to afford ample lateral support to said rings when they are subjected to violent shocks. All shocks or concussions which have a tendency to force upward the rings O C are transmitted directly to the wheel-shaft A by the grooved wheels D D, and therefore no injury can result from such concussions. The sides of the grooves in the periphery of each of the wheels D D act in conjunction with the grooved wheels E E in affording the proper lateral support to the rims O O of my improved paddle-wheel. The holes in the outer ends of the bucketarms h h, which receive the pivot-bolts that connect said arms to the rings O C, are made of an oblong shape, as shown in Fig. 5. This shape 0f the aperture in said bucket-arms, taken in connection with the grooved wheels D D on the shaft A, prevents the concussions which may throw upward the/rings' C C from acting on and bending said arms. The Weight of the said rings C O is sustained entirely by the arms h 71, but any concussion which may 2. In connection with the combination of the Wheels D D With shaft A in such positions as to bring them Within the inner peripheries oi' the rings C C, making the holes in the outer ends of the arms h h of an oblong shape, for the purpose substantially as herein set forth.

JOSEPH G. SHANDS.
