PROPELLlNG-WHEEL.

SPECIFICATION forming part of Letters Patent No. 352,299, dated November 9, 1886.

Application filed March 1, 1886.

.To aZZ whom it may concern:

Be it known that I, MosEs S. COLE, a citizen of the United States, residing in the city,

of Rivas, Republic of Nicaragua, Central America, have invented a new and Improved Propelling-Wheel, of which the following is a full, clear, and exact description.

The object of my invention is to provide a new and improved propelling-wheel which has its wings open through a certain part of its revolution and closed through the remainder of the same.

The invention consists of cams which, in connection with rotating spokes or arms, operate sliding bars which open the wings of the wheel during a certain part of a revolution and lock the same in this open position.

The invention also consists of various parts and details and combinations of the same, as will be fully described hereinafter, and then pointed out in the claims.

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

. Figure 1 is a side elevation, with parts removed, of my improved propellingwheel.

Fig. 2 is a face view of one of the cams. Fig.

3 is'a sectional plan view of one arm and cam connections, showing the wings closed. Fig. 4 is a similar view showing the wings open; and Fig. 5 is a cross-section on the line a; m, Fig. 4. Fig. 6 is a detail perspective view.

My improved propelling-wheel is specially adapted for aerial vessels such as are described in my application for Letters Patent filed with this application; but it can also be used for propelling steamers and boats, or for fans or other purposes.

The brackets A A, carrying my propellingwheel B, are attached to the vessel or apparatus which is to be provided with my improvement. To the inside of each outer end of the brackets A is secured a cam, 0, having a cam-groove, G, and an aperture, 0*,through which passes the shalt D, provided on its outer ends with crank-arms D, which are connected with the driving machinery of the vessel or apparatus. Between the camsO is placed a bracket-wheel, E, secured on the shaft D, so

as to rotate with the same when the latter is set in motion.

The bracket-wheel E is provided with two, three, four, or more spokes, E, from the end of each of which extends a wingarm, F. Each spoke E is provided with a central aperture, E", and a side recess, E

'An arm or bar, G, having on its inner end a head, G, is mounted to slide in a recess, F, formed on the wing-arm F, and its head G passes into the central aperture, E of its spoke E, and is held. in place therein by the guidepins H and H, extending into the side recess, E The pin H extends beyond the said side recess, E and passes into the grooves O of the cams O. The bar G is held in place in the recess F of the wing-arm F by the ,coverplates F On the face of the wingarm F, on each side, are hinged the wings I, each of which consists of a frame, I, covered with canvas orother suitable material, and provided with two, three, or more lugs, 1 extending at right angles to the arm F when the wings I are open, and resting flat upon the face of the arm F when the wings I are closed.

Three or more wedge-shaped pieces, J J J', are secured to the upper edge of the sliding bar G, and the center one, J, is provided with a cross-piece, J having on each end a beveled locking'piece, J, which engages with a piece, 1 attached to the wing-frame I when the wing is closed. The under side of the arm F is incased by a wedge-shaped cover, K, of sheet metal or other material, so as to present but little resistance in passing through water or air.

The operation is as follows: The cam-groove O of the cam 0 consists of the part a, which is concentric with the aperture 0 and forms a semicirculargroove ofthe parts I) and b, which extend from the ends of the groove a at an angle of about forty-five degrees and continue into the-concentric groove 0 in an angle of ninety degrees, so that the respective pins H of the sliding bars G enter alternately the parts a, b, c, and 1), whereby the bar G is moved toward or from the central aperture, 0', of the cam C. This motion of the sliding bar G causes the wings I to open as soon as the pin H leaves the part a of the groove 0' and enters the part b,

and to open to the greatest extent when the pin enters the part 0, remaining open while the pin passes through the part c. The wings can begin to close as soon as the pin H reaches the part b, and are free to close entirely when the pin H enters the part a of the groove 0. The closing of the wings is accomplished by the resistance of the air through which the wings pass. A constant rotary motion is imparted to the bracket-wheel E by the shaft D and its connection with the driving machinery attached to the vessel or apparatus to which my improved wheel is attached. The motion is in the direction of the arrow a. The rotation "of the bracket-wheel E causes the pins H, on

entering the parts b of the cam-grooves O, to

J pass over the pieces I when the wings are fully opened, and thereby lock the same in this open position until the sliding bar G commences to recede from the axis of the shaft D, which is done as soon as the pins H enter the parts b of the grooves 0'. As soon as the pins H have reached the parts a of the grooves C, the wedge-shaped pieces J, J, and J 2 and lugs J are out of contact with the respective lugs l and the cross-pieces I of the wing-frames I, so that the wings I, being free to close, are forced to a closed position by the resistance of the air with which they come in contact on the rotation of the bracket-wheel E, and remain closed until the pins H have traveled through the parts a of the grooves, after which the opening and closing is again accomplished, as be-' fore described. a

It will be seen that all the wings I, attached to their respective bars G, sliding in the spokes E of the bracket-wheel E, are alternately opened and closed by the action of the pin H in the groove 0 of the cam G, and by the resistance of the air through which the wings pass.

- It will be seen, further, that the wings are open only through onequarter of the entire revolution, and are completely closed through one-half of a revolution of the bracketwheel E, the remaining one-quarter being necessary for the opening of the wings, as above described, and the closing of the same by the resistance of the air.

Having thus fully described my invention, I claim as new and desire to secure by Letters Patentas shown and described.

2. In apropelling-wheel, the combination of a cam and a bracket-wheel having spokes each provided with a wing-arm, and wings hinged to the said arms and consisting of a frame covered with canvas and provided with lugs, with a sliding bar provided with wedge-shaped pieces which engage the logs on the wingframe, and provided with pins extendinginto the groove of the cam, substantially as herein shown and described.

3. In a propelling-wheel, the combination of a earn, a bracketwheel provided with spokes, each having a wing-arm, and with wingshinged on each arm and provided with lugs, with a sliding bar provided with wedgeshaped pieces, and a locking device consisting of lugs secured to the sliding arm and passing over bars attached to the wing-frame, and with pins extending into the groove of said cam, substantially as herein shown and described.

4. 1n apropelling-wheeh the cams 0, having grooves O, the shaft D, provided with crankarms D, and the bracket-wheel E, provided with the spokes E and the arms F, in combination with the hinged wings I, having lugs I, the sliding bar G, having wedge-shaped pieces J, J, and J which engage with the lugs I of the hinged wings I and lockingpl'ates J, and the pins H and H, substantially as herein shown and described.

5. In a propelling-wheel, the earn 0, having a cam-groove, O, the bracket-wheel E, provided with the spokes E, each having the aperture E and recesses E the arms F, having recesses F, and the hinged wings I, each having a frame, I, provided with lugs I on pieces I, in combination with the sliding bars G, provided with the wedge-shaped pieces J JJ and lugs J, which engage with the lugs I" andthe pieces 1 respectively, of hinged wings I, and the pins H and H, substantially as herein shown and described.
