MEANS FOR PROPELLING VESSELS.

SPECIFICATION forming part of Letters Patent No. 457,426, dated August l1, 1891.

Application filed August 15, 1889.

T aZZ wiz/ont it 171,603/ concern:

Be it known that I, CHARLES JOSEPH MENGES, of Kansas City, Jackson county, Missouri, have invented certain new and useful Improvements in Means for Propelling Vessels, 0f which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming4 a part hereof.

My invention relates to hydraulic motors as applied for the propulsion of vessels; and it consists in a certain novel construction and arrangement of parts, as fully described hereinafter and claimed.

In the drawings, Figure l is 'a sectional view on the line of Fig. 4, showing avessel provided with my motor. Fig. 2 is a detail view showing the end of one of the grooved blocks which carry the oars. Fig. 3 is a side elevationof the same, partly in section. Fig. 4 is a plan view of the vessel, partly broken away. Fig. 5 is a side view, partly broken away. Fig. 6 is a detail view of one of the trip-pins.

A represents a steamboat having a central longitudinal open space, in which, near its ends, are mounted vertical power-wheels C C,

having shafts 7s 7s, said wheels being provided with radial arms f, the outer ends of which are concaved or notched to engage transverse bars 69 of the sprocket-chain V. These bars are connected together at regular intervals by the links D, which carry uprights F at their forward ends, said uprights being provided with horizontal stop-pins 122, against which hinged paddles E, which are carried by said chain, bear when the paddles are encountered by the current of the stream in which the boat is being navigated. Parallel tracks 70 71 are arranged adjacent to the upper and lower ends of the chain, respectively, on

l which operate rollers L, mounted on the bars Serial No. 320,842. (No model.)

push against the bottom of the stream when the oars are pushed rearwardly, and the upper ends of the latter are hinged to the sliding sleeves S, which are loosely mounted onhollow tubes O', that are secured to sliding grooved blocks N, whereby the lower ends of the oars are enabled to adapt themselves to the uneven surface of the river-bed. The hinged ends or wings h are pivoted at t' to the oars in such a position as to bear against fin-shaped strips j to limit their backward movement.

The oars receive their' mo'tion from chains R R, which operate on sprocket-wheels T T', mounted on shafts b b', said shaft D being provided with gears s, which mesh with gears r, which in turn mesh with gears q, that are mounted on the shaft 7c of power-wheel C. A trip-lever Q is mounted on the block N and is provided at its free end with a crosshead, the ends of which are adapted to engage alternately with the upper and lower portions of the chains R R whereby when they are engaged with the upper portions of said chains the blocksN are carried forward, and when engaged with the lower portion they are carried rearwardly. The trip-levers' are provided with arms P P, which engage pins p at the end of each stroke to reverse the position of the levers, and a spring R engages the rear concaved end of the lever to hold it in engagement with the chain until released or tripped by the arms P. Thus the blocks which carry the oars are alternately carried forward and backward the entire length of the vessel, and when they are carried backward the oars engage in the bed of the river and thereby assist in pushing the vessel forward. ,l

From the above it will be seen that the action of the current on the paddles carried by the chain when the vessel is' headed upstream operates the oars automatically, thereby partially overcoming the resistance of the current and assisting the motive power used to propel the vessel.

To insure the perfect operation of the blocks N, I provide them with grooves 5 to travel on tracks V V. g

In Figs. 'Zand 8 are shown propellers 37, which are provided with paddles 38 and 41. Paddles 38 are pivoted at 39 to the rim ofthe IOO wheel, and stop-pins 40 are arranged to engage the inner ends of said paddles when lthe propeller-shaft is mounted in the rear ends of the arms 34, which are pivoted at intermediate points and are connected at their ends to adjusting-screw 35, having sprocket-Wheels 36 on their upper ends, which are connected for simultaneous operation by the sprocketchain 6 4. These sprocket-wheels are provided with handles 62 to enable them to be rotated to-elevate or depress the front ends of the arms 34, and thereby adjust the propellers to the desired height. An arm 47 is mounted at its upper ends on the propeller- 1 shaft 60, and carries at its lower end a sprocketwheel 48, which engages a horizontally-dis.' posed chain 49, which is secured in any suitl, able manner at its ends, and is arranged be-V neath the surface of the water in the path of A guide-roller 87 depends fromA the vessel. the lower end of the arm 47 and bears against the under side of the chain 49 to hold the latf ter in contact with the sprocket-wlieel 48. A sprocket-wheel 45 on the shaft of the wheel 48 1s connected to a sprocket-wheel 44 on the Q propeller-shaft by means of achain 46, wherei by the rotation of the propeller is cominunicated to sprocket-wheel 48,which travels along j the chain and thereby moves the vessel for-f ward.

the chain 3l, and the crank-wheel is connected or lowered independently of sprocket-wheel 48 I employ an adj usting-arm 55, which is pivoted at its lower end to the arm 47 and passes at `its uppery forked end through slots in the progecting strips 58, the extremities of saidj forked ends being engaged by nuts 56.

are mounted three pulleys 24, which are connected by means of a cable 22, which passes around their peripheries, and the upper ends of the piston-rods 2l, which operate alterj nately, are slotted to enable said cable to pass therethrough. The movements of the pistonrods oscillate the central pulley 24, causing it to turn through a half-revolution at each stroke, thereby rotating the crank-wheels 32, which are connected to the central pulley by crank-rods 28. 4 H H represent rudders, which are mounted on vertical shafts a at the opposite ends of the vessel in bearings ct', and the upper ends of said shafts are provided with sprocketwheels M M', which are connected together for simultaneous operation by the chain Gr. The forward shaft carries a gear-wheel J, which meshes with a gear-wheel J', that is carried bythe shaftA of lthe pilot-wheel K.

Having thus described my invention, I claiml.
