MOTOR.

SPECIFICATION forming part of Letters Patent No. 350,257, dated October 5, 1886 Application filed January 14, 1886. Serial No. 189,746.

To all whom it may concern.-

Be it known that I, WILLIAM LAY, of Omaha, in the county of Morris and State of Texas, have invented a new and Improved Propeller for Boats, of which the following is a full, clear, and exact description.

The object of my invention is to provide a new and improved propeller for boats which is simple in construction, prevents loss of power, and is thus very economical.

The invention consists in the construction and combination of parts and details, as will be fully described and set forth hereinafter, and then pointed out in the claims.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

2 is a longitudinal sectional elevation of the same. Fig. 3 is a plan view of the same. Fig. 4 is a cross-sectional view of the same.

The shaft A is provided with the crank B, and the end parts, A, of said shaft are passed through the sleeves 0, formed on and projecting from the disks 0, united at their rims by pairs of rods D. The sleeves O are journaled in boxes 0 on the bars E, projecting from the stem of the vessel. On the crank B the rings F are mounted to turn, and from said rings the rods F project, which are united in pairs by the frames F in which the blades or wings F are secured. Each frame F is passed between two rods, D, of a pair. On the sleeves G the sprocket-wheels G are mounted, over which the driving-chains G pass, which are also passed over the sprocket-wheels G on the driving-shaft G which is operated by the engine. On the ends of the parts A of the shaft Athe bow-springs H are rigidly mounted, and in the forked ends of the said springs the short shafts H are mounted, on which the ends of cables or chains Iare secured, which are passed over pulleys I on the ends of a shaft, 1 mounted on the frame 1 Each shaft H hasa squared end for receivinga key for turningit, and on each shaft a ratchet-Wheel, H is mounted, with which a pawl, H on the springH engages. By turning the shafts H the cables or chains I can be tightened as much as may be necessary. On the shaft 1 the worm-wheel (No model.)

J is rigidly mounted and engages with the worm J on the shaft K, journaled on the frame I at right angles to the shaft 1, and carrying the hand-wheel J On the shaft K the two pulleys L and M are loosely mounted, and are provided with the clutch-collars L and M, which can be engaged with the opposite ends of the clutch-sleeve N, mounted to turn with and slide onthe shaft K between the clutch: collars L and M, and held in the projection N of the bar N mounted to slide parallel with and below the shaft K. The upper. end of a lever, O, pivoted at O, can act on the sliding bar N and is connected with a rod, 0 by' means of which the saidlever O can be shifted from the engine-room or pilot-house or other part of the vessel. The lower end of the lever 0 is engaged with the upper end of the crank on the shaft P, which crank is provided on itsends with the pins P P, which are passed through the slots R S in rods R and S, connected with the opposite arms, R S", on the ends of the shaft A. Over the pulleys L and M the belts Q and T are passed, the latter being crossed to reverse the motion, and said belts are also passed over the pulleys Q and T on the shaft U, driven by bevel-gearing from the main shaft G The operation is as follows: The paddles are mounted to turn on the crank, and are eccentric to the disks 0, and as they descend they are projected farther beyond the rims of the disks 0, so that they can dip into the water, and as they rise they are drawn back again. The dip of the blades can easily be regulated as necessity may require. When the blades are to dip less, the front ends of the springs H-that is, the ends toward the stern of the vesselmust be swung down, and when the blades are to have more dip the rear ends of the blades must be swung down. To accomplish this the hand-shaft l is revolved either by means of the hand-wheel or by means of the belts Q T. By shifting bar N z by means of the lever Q and the rod 0" the clutch-sleeve N is arranged with either the clutch-collar Lor M, and the shaft K is revolved in one direction or the other, and thus the crank B is swung up or down and the paddles raised or lowered. When the desired position of the paddles has been secured, the motion of the shaft K is stopped by hand, operating the rod 0 and hence bar N If not stopped before the crank reaches its extreme positions, the belts Q T must be shifted automatically, which is accomplished in the following manner: As the crankshaft turns, the arms It S turn with it, and thereby the rods It and S are moved, and when the springs and the crank-shaft have been turned as far as necessary the ends of the slots It and S strike the pins P I? and shift the lever P, which acts on the lever O, the same in turn acting on the bar N The paddles or blades can he removed entirely from the water, which is a matter of great importance.

Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. In a motor, the combination, with a crankshaft, of blades or wings mounted to revolve on the crank part of the shaft, disks mounted to revolve on the shaft at the ends of the crankrods uniting the disks and guiding the wings, the springs H on the ends of the shaft, met-hanism lor raising or lowering either end of the said spring, and mechanism for revolving the disks, substantially as herein shown and described.

2. In a motor, the combination, with a crankshaft, of paddles or wings mounted to revolve on the crank part of the shalt, disks mounted to revolve on the shaft at the ends of the crank part, guides for the paddles or wings on the disks, the springs H on the ends of the shalt, the cables or chains I, secured on the ends of the springs and passed over pulleys, mechanism lor revolving the said pulleys "from the main driving shalt, and mechanism for revolving the disks, substantially as herein shown and described.

3. lna motor, the combination, with a crank shaft, of paddles or wings mounted to revolve on the crank part, disks mounted to revolve 011 the shaft at the ends of the crank, the springs H on the ends of the shalt, the cables or chains I, secured on the ends of the springs II and passed over the pulleys, mechanism .for revolving the said pulleys from the main driving shaft, a belt-shifting device for said driving mechanism, which belt-shifting device is operated from the crank shaft, and mechanism. for revolving the disks, substantially as herein shown and described.

at. In a motor, the combination, with the crank-shaft A B, of paddles or wings mounted torevolve on the crank part, the disks 0, mounted to revolve 0n the end parts of the shaft, and having guides for the paddles or wings, the springs II on the ends of the shaft A, the shafts H on the ends of the springs H, the ratchet-wheels I'I on said shafts, the pawls H engaged with said ratchet-wheels, the cables or chains I, secured on the shafts H, the pulleys I, over which the said cables or chains are passed, mechanism for revolving said pulleys, and mechanism for revolving the disks, substantially as herein shown and described.

5. In a motor, the combination, with the crankshaft A B, of paddles or wings on the crank part of the shaft, disks on the shaft at the ends of the crank, guides for the paddles or wings on the disk, mechanism for revolving the disks, the springs H on the ends of the shaft, the cables or chains I, the pulleys I on the shaft I, the worm-wheel J on the shaft 1 the shaft K, the worm J on the same, the pulleys L and M, mounted loosely on the shaft K, and having clutch-collars, the clutelr sleeve N, and the pulleys Q T on a shaft driven from the main shaft, substantially as herein shown and described.

6. In a motor, the combination, with the crank-shalt A B, of paddles or wings mounted to revolve on the same, the disks 0, mounted to revolve on the shaft at the ends of the crank, guides for paddles on said disks, the springs H on the ends of the shaft, the pulleys l on the shaft 1', the cables or chains I, the wormwheel J on the shaft l", the shaft K, the worm J on the same, the pulleys L and M, mount ed loosely on the' shaft K, and having clutchcollars, the clutch-sleeve N, the sliding bar N", the levers O and 1?, bars R and S, and the arms It and S" on the ends of the shaft A B, substantially as herein shown and described.
