JAMES A. 110mm, or DENVER,

' 'PROPELLING MECHANISM.

Application filed September 13,1915, Serial No. 50,418;

To all whom it may concern Be it known that I, JAMES A. HORNE, a citizen of the United States, residing at Denver, in the county of Denver and State of Colorado, have invented certain new and useful Improvements in Propelling Mechanism, of which the following is a specification.

This invention relates to propelling mechanism for boats and aeroplanes, and has for its object the provision of a simple mechanism by which a vessel may be driven either forwardly or backwardly at a high speed and with a small expenditure of power.

The invention is illustrated in the accompanying drawings and will be hereinafter fully described, the novel features being particularly pointed out in the claims following the description.

In the drawings:

Figure 1 is an elevation of my improved propelling mechanism applied to a boat;

Fig. 2 is a plan view of the same;

Fig. 3 is a detail perspective view of the propelling mechanism removed from the boat;

Fig. 4. is a detail section of the propelling blade or bucket.

In carrying out my invention, I mount in suitable bearings in the hull'or upon the deck of a vessel hollow driving shafts 1 which are in axial alinement but have their inner ends spaced apart. The outer ends of these driving shafts project beyond the sides of the vessel and are equipped with radial arms 2 which are rigid with the shaft and are spaced apart and have propelling blades or buckets 3 supported between their outer ends. These blades or buckets are of arcuate form and are open along the chords of the arcs described by their outer convex surfaces. These open sides of the blades are shown at 4: and it will be readily noted that the buckets or blades consist of two arcuate side plates between the curved edges of which extend the covers 5. Through the ends of the arms 2 and through the said side plates of the blades or buckets, I insert pivots or shafts 6 which are secured fixedly to the buckets and have their outer ends bent laterally to present cranks 7, as clearly shown. These cranks 7 are connected by links 8 which extend parallel with the radial arms 2 and are pivotally mounted at their centers upon the cranks 9 formed at the outer ends of a reversing or Specification of Letters Patent.

I equipped at its center with COLORADO, Assrcavoie, BY MESNE ASSIGNMENTS, 'ro EDWARD 1.. CLOVER. I 1 i Patented J uly 30, 1918; Renewed February 9, 1918. Serial a... 216,401.

controlling shaft 10 which extendsthrougli the alined hollow driving shafts 1 and is a reversing lever 11 which may be operated from the pilot house. Upon the driving shafts 1, I secure pinions or pulleys 12 which are adapted to receive power from the engine and transmit the same directly to the shafts, as will be readily understood.

Power being applied to the driving shafts 1, the said shafts will be rotated and the radial arms 2 carried by the said shafts will be caused to swing about them as centers and thereby carry the buckets or blades down into the water and, inasmuch as the inner concave surfaces of the blades will be presented to the water, a be obtained which will serve to move the vessel forward. As the shaft swings around, the bucket will be lifted from the water and any liquid which may remain in the bucket will readily drain therefrom over the lower end of the same. The arrangement of the several cranks 7 and 9 and the link connecting the same will tend to hold said cranks in a vertical position so that the straight edges of the buckets will always remain vertical and the desired travel of the vessel upon the water obtained. Should it be desired to reverse the motion so as to drive the vessel backward, the reversing lever 11 is swung over so as to rock the crank shaft 10 through one-half of a revolution and thereby 2 swing the crank arms 7 and 9 to a position above the supporting arms 2, as a result of which action, the buckets will be swung with the shafts or pivots 6 and their straight edges brought forward. If the engine be then reversed and set in motion, the buckets will engage the water in the same manner as previously described but will present the opposite faces to the water so that the resulting travel of the vessel will be backward. Any desired or convenient means may be employed to permit the shifting of the controlling lever 11 by the pilot and it will be read: ily understood that the shaft 10 is at rest except when it is being rocked to reverse the propeller.

It will be readily noted that my device is composed of very few parts which are simple in their construction and free of complicated arrangements. The device can be instantly reversed so that no time will be lost in changing the direction of travel of the vessel. It

powerful leverage will 7 will be readily understood, of course tha t the propellers may be duplicated and any desired number or sets of the propellers may be provided according to the size of the vessel to which they are applied.

Having thus described the invention, what is claimed as new is:

In a propelling mechanism, a hollow shaft, radial arms carried by said shaft and spaced 1 apart, pivot shafts mounted for rotation in said arms and each having a crank, a bucket fixed to each of said pivot shafts between said arms, a rock shaft extending through said hollow shaft and having a crank, a link connected to the cranks of said rock shaft and of said pivot shafts, means for holding said rock shaft and reversing its position, and means for rotating said hollow shaft.

In testimony whereof I affix my signature.
