PATENT -OEETCE PADDLE-WHEEL.

SPECIFICATION forming part of Letters Patent No. 744,539, dated November 17, 1903. Application tiled I une 6. 1903. Serial No. 160,425. (No modeL) To @ZZ whom,v it may concern:

Be it known that I, GEORGE L. HAMLING, a citizen of theUnited States, residing at Farmington, in the county of Kent and State of Del,

aware, have invented new and useful Improvements in Paddle-VVheels, of which the following is a specification.

My invention relates to new and useful improveinents in paddle-wheels for use in propelling boats.

An object is to provide a wheel of simple, inexpensive, and durable construction, which overcomes the vibration incident to the use of propellers and which is capable of propelling a boat at high speed. With the above and otherobjects in view the invention consists in providing a wheel comprising a hub, in the opposite ends of which are arranged detachable blades, These blades are so inclined that when revolved the water contacted thereby will be forced toward the center of the wheel. As a result all vibration, such as occurring by the use of ordinary propellers, is dispensed with, and by packing or forcing the Water toward the center of the wheel-a high speed can be attained by the use of this wheel.

The invention also consists in the novel construction, combination, and arrangement of parts hereinafter more fully described and claimed, and illustrated in the accompanying f drawings, in which- Figure l is an end elevation, and Fig. 2 is a side elevation thereof.

Referring to the gures by numerals of reference, 1 is a shaft to which are secured drums 2, the inner ends of which are connectf ed by cross-strips 3. These drums and strips form the hub of the paddle-wheel and are adapted to rotate with the shaft l-. Blades 4: extend from each drum 2,l and the inner ends by means of bands 6, which are secured toy the blades in any desired manner.

It will be understood that when the paddlewheel is rotated inthe direction indicated by the arrows in Figs. l and2 the Water contacted thereby will be forced inward to points between the two series of blades, where it will be packed and increase the resistance odered to the rotation of the paddle-wheel. Moreover, as the water is thrown in. opposite directions by the two series of blades no vibration will result, as is the case where the water is thrown in the same direction by all of the blades. The wheel is extremely simple and inexpensive in construction, and should any one of the blades become roken or worn it can be readily replaced by detaching it from the bands 6 and removing the securing means 5 at its inner end. v

Having thus described the invention, what I claim as new, and desire to secure by Letters Patent, is-

In a paddle-wheel the combination with drums and strips connecting the saine, of series of oppositely-inclined blades extending `from the drums, means for detachablysecuring the blades to the drums, and bracingbands connecting the blades.

In testimony whereof I affix my signature in presence of two witnesses.

GEORGE L. HAMLING.
