Application filed July 17,
This invention relat'e'sto improvements in boats of the type in which a suitable motor is installed for propelling purposes. The propelling mechanism proper comprises in general, an endless chain which is located on the opposite sides of the boat to the alternate links of which are attached blades that engage the water for moving the boat forward or rearward. Located between the blades is a link which is formed with an opening to receive the teeth-of the driving gear wheels that are suitably geared to the motive power of the boat. I V
Devices for steering the boat are provided which comprises a drum around which is coiled a cable that extends to the opposite front sides of the boat. This cable is so connected and arranged as to simultaneously fan , teeth 8 and flat surface 8.
operate the two rudders in the same direction.
Referring to the drawings Fig. 1 is a plan view showing the motive power located within the boat, the gearing connection between the motor and the endless propeller chains, also the means for steering or guiding the boat.
Fig. 2 is a side elevation of Fig. 1 illustrating one of the rudders.
Fig. 3 is a plan View of a short section of the propeller chain and one of the blades.
Fig.4 is a side elevational view of Fig. 3.

Fig. 7 is a detail o'fone of the supporting bearing blocks for the-rudder. V
referring to the drawings in detail:
1 designates the body portion of the boat. 2the driving motor of suitable type; as gasoline, like those used in motor vehicles. The transmission box 3 and bevel gearing 4 which transmits motion to the driving .shaft 5 is shown in Fig. 1. This shaft is located in boxes 6. On the shaft 5 at its opposite ends is secured a gear wheel 7 7 shown in detail in Fig. 5 having the gear Secured to the side of the boat are boxes 9 which may be adjustable for supporting theyshaft 10 on which a second gear Wheel 11 like wheel 7 loosely turns. Passing around the gears 7 .and 10 on each side of the boat is the propelling chain indicated .as a whole by the reference numeral 12, These chains are composed of the links 13 and 14 having 19%;; Serial No. 123,108.
openings 15-and 1'6to receive the teeth of the gears. The links are connected together: by means of the pins 17,'which pass through sleeves 18. The ends of the pins project beyond the outer sides of the plates 19 and I p 20 where they are headed over. Located between the plates 19 and 20 are the propellerplates 21. They are secured to the plates by means of the rivets 22. i
The openings 15 in the links 13 and the openings 16 in the links 14 are for receiving the teeth 8 of the gears 7 and 11,. whereby v the endless propeller chains 12 are actuated from the. motor.
venting the water from being thrown 'over the edge of the boat when the propellers are are the rudders 26, the shafts being sup Suitable'clutch means is operatedby the rod 23. 24 is a cover which ls'attached to the side of the boat for prep ported in the bearing blocks'34 through which they pass as indicated by the opening 34.
The advantages of locating. the propeller chains on the opposite sides of the boats is that they assist in supporting the boat on I even keel, the water line being indicated at 37. The plates. 21 being secured to the blades 19 are efficient in moving the boat forward, and if the engine is reversed in stopping the boat, or, for propelling rearwardly. The securing of the plates between the blades 19 produces a very rigid propeller and the gear teeth 8 which enter the openings 15 and 16 have a long bearing on p the fiat surface 38 of the gear 8. I The plates 19 and 20 further assist in maintaining the boat in astraight line since the water would engage the sides of the jblades.
The gear wheels 7 and 11 may, if desired,
be formed aspontoons to assist in floating the boat.
The rod for operatingthe transmission gears is indicated conventionally at 38. hat I claim is; s
'1. A propeller chain for @he --pu,;rp0se de scribe'dcomprising a plurality offlat links "with openings, means for pivotallypcolmecb in}; the links together, "side plates securecl to the alternate links, blades :s eeurecl to 'i-lie' plates and located transversely of the plates, l 2.
