20 Claims. (01. 4692) This invention relates to mechanical paddle canoe toys, particularly of the type in which a double paddle is employed, and has for its object the provision of improved and simplified mechanism for operating the paddle and simulating the natural bodily movements of a paddler.

In the accompanying drawings, I have illus-- trated a number of embodiments of my invention. In these drawings, Figure 1 is a perspective view of a toy canoe showing an automaton seated in the canoe and holding a double paddle; Figure 2 is a longitudinal, vertical section along a plane parallel to the keel of the canoe and showing the paddle-operating mechanism in side elevation; Figure 3 is a vertical, transverse sec tion taken along line 3-3 of Figure 2; Figure 4 is a horizontal section taken along line 4-4 of Figure 2; Figure 5 is a horizontal section taken along line 5-5 of Figure 2 showing the bottom of the mechanism; Figure 6 is a view similar to Figure 2 showing a modified form of the mechanism; Figure '7 is a section taken along line 1-1 of Figure 6 showing the bottom of the mechanism shown in that figure; Figure 8 is a vertical transverse section taken along line 8-8 of Figure 6; Figure 9 is a view similar to Figures 2 and 6 showing a further modified form of the mechanism; Figure 10 is a detail of a further modification; and Figure 11 is a view of the shirt or jacket for the automaton in the canoe.

The toy shown in these drawings comprises a small skiff or canoe I, provided with a deck 2, in the cockpit 3 of which is seated an automaton 4 whose arms hold a double paddle 5. The mechanism, which I shall presently describe, moves the arm extremities or hands of the automaton in ellipsoidal paths and in such phase relationship that the blades of the double paddle are dipped in the water, moved astern and lifted from the water in proper sequence, thus simulating the natural movements of a paddler propelling a boat forward.

In Figures 2, 3, 4, and 5, I have illustrated one form of mechanism for operating the paddle. As shown in these figures, the head 6 of the automaton is mounted upon the upper end of a vertical rod I secured at its lower end to a transverse plate 8 screwed to the underface of the deck. Mounted upon the plate 8 for oscillation about the rod I are a pair of uprights 9 and III. The upright 9 carries at its upper end a horizontal transverse bar I I, which constitutes the shoulders of the automaton, and terminates at its lower end in a plate or offset I2, the forward end of which is pierced at I3 to receive the rod I and from the rear end of which depends a fork I4. Similarly the other upright II] carries at its upper end a horizontal transverse bar I5 and terminates at its lower end in a plate I6 having at one end an aperture II for receiving the rod 1 and at its other end a depending fork I8. The outer ends of the bar II terminate in depending flanges I9 upon which arms 20 are pivotally mounted. These arms are permanently crooked at the elbow and are provided at their outer extremities with holes 2I for receiving pins 22 affixed to the paddle 5. The arms being of spring metal, the paddle is mounted and demounted by springing the arms inwardly to clear the inwardly extending ends of the pins 22. As clearly illustrated in Figure 4, the space between the pins 22 is sufficient to provide for variations in the spacing of the arms as they assume varying positions during the paddling operation. The upper parts of the arms 20 are provided with slots 23 through which project the ends of horizontal bar I5.

Mounted upon the underface of the plate 8 is a bearing bracket 24 in which is journaled a crankshaft 25 terminating in cranks 26, which extend within the slots of the forks I4 and I8. As shown in Figure 2, these cranks are angularly displaced relatively to each other. A spring motor 21 is mounted upon the underface of the deck just forward of the mechanism just described and through an angle arm 28 contacting with an extension of the forward crank 26, rotates the crankshaft 25. The motor 2! is provided with a winding stem 29 extending upwardly through the deck and terminating in a wheel 30 simulating a life-preserver.

The mechanism just described operates as follows: Rotation of the crankshaft 25 acts through cranks 26 and forks I 4 and I8 to oscillate the horizontal bars II and I5 through limited arcs about the vertical axis of rod 1. As the cranks are angularly displaced relative to each other the bars II and I5 oscillate out of phase, the exact phase relationship being determined by the angular displacement of the cranks. The oscillating bar II carries the arms 20 with it, and as the bar I5 is oscillating at the same time, and as the ends of this bar make a sliding contact with the arms through the slots 23, the arms are made to oscillate about their pivots, and these oscillations are also out of phase. As a result of these horizontal and vertical oscillations, the forward ends of the forearms or hands of the automaton describe ellipsoidal paths and swing the paddle 5 to propel the canoe.

For most satisfactory operation the paddle blades should be in a substantially vertical plane when dipped into the water, during the stroke, and when lifted from the water. To this end the rear face of the paddle handle adjacent the pins 22 is made fiat and the ends of the arms have straight edges disposed at an obtuse angle to each other so as to bear on these flat areas on opposite sides of the median line of the paddle when a blade is in the water. Figure 2 illustrates the paddle with one blade immersed and the other elevated. The end of the upper arm bears against the lower side of the flat area adjacent its pin 22 while the end of the lower arm bears against the upper side of the flat area adjacent the other pin 22. Thus the blades are held in vertical position when in the water.

In the modified form of apparatus shown in Figure 6 the mechanism extending above the deck of the canoe is substantially the same as that just described. In the mechanism below the deck, however, I have made certain changes, notably in the motor and its winding mechanism and the location of the forks l4 and 18. The fork M which oscillates the horizontal bar I I remains as before, but the fork l8, which oscillates the bar I5, is placed at the rear closely adjacent the fork I4. Thus both forks are on the same side of the axis of vertical oscillation and on the side opposite the forearms of the automaton and hence of the paddle. A better balance of the mechanism is thus effected. This change involves necessarily a change in the position of the cranks both of which are mounted on the same end of the crankshaft.

Instead of the ordinary spring motor 21, as shown in Figure 2, I have here provided a motor in the form of two rubber bands 3| each of which is secured at one end to a bracket 32 depending rom the deck, and at their other end to a hooked extremity of the crankshaft. Rotation of these rubber bands about their common axis, when under torsion, rotates the crankshaft and cranks, and through the forks operates the paddle as described previously. By using two rubber bands I get the propulsion effect of a single long band but with the advantage of balance, the longitudinal pull of each band on the operating mechanism being equal and opposite.

I have provided the following mechanism for winding this motor; the vertical rod 7 which supports the head 6, instead of being fixed at its lower end upon a transverse plate, is journaled within that plate and is provided at its lower end with a crown gear 33 meshing with a pinion 34 upon the crankshaft. To twist the rubber bands and thus wind the motor, the head 6 of the automaton is turned. In order to prevent untwisting of the rubber bands during the winding operation when fingers are temporarily removed from the head to secure a new grip, the crown gear 33 is mounted so that its periphery makes frictional engagement with one wall of the bearing bracket 24. This frictional engagement is sufficient to prevent unwinding of the rubber bands until the torsion created by the winding operation has reached a predetermined point. After this point is reached rotation of the crown gear 33 is reversed until the torsion of the rubber bands and the friction between the crown gear and the bearing bracket reach equilibrium. Thus overwinding and consequent breakage of the rubber band motor is improbable. At the same time I have simplified and cheapened the mechanism by doing away with a ratchet. In order to permit the torsion motor to perform its intended function after it has been wound I withdraw the crown gear from engagement with the pinion by pulling upward on the head 6. When this disengagement has taken place the rubber bands are free to rotate the crankshaft and operate the paddle.

It will be noted that nothing projects above the deck except the torso of the automaton, thus giving an effect of naturalism. The motor is started, stopped and wound through means controlled by the head of the automaton, and the head may be left in any desired angular position thus adding another naturalistic touch.

The form of apparatus shown in Figure 9 represents a still further simplification of the mechanism. In this apparatus I have but one bearing for the crankshaft 25 and but a single rubber band 3|. I have also eliminated all gears and pinions and have provided a simplified means for winding the torsion motor. The forward end of the rubber band 3| is connected to a string or other similar flexible connection 35. This string extends upwardly through a tube 36 and terminates in a knob 37 mounted on the upper side of the deck and held in frictional engagement therewith by means of a spring 38. When holding the paddle, the rubber band can be twisted by turning the knob 31, the frictional resistance of the string 35 in the tube 36 being sufficient to permit this. Overwinding, however, is prevented by slippage of the string when the torsion of the band has reached a predetermined value.

In Figure 10 I have illustrated a modified form of winding knob and connections. The knob 39 is rotatably mounted on the deck of the boat and is provided with a bore 40 and a transverse slot 4! across its top face. The end of the rubber band extends upwardly through the bore, divides in the slot, and the loop extends under the head of the knob. Two bands might be used if desired. With this form of winding knob it is a simple matter to replace a broken rubber band.

In Figure 11 I have illustrated the jacket or shirt with which the automaton is clothed. This garment is substantially T-shaped, the stem of which is provided with a slot 42 and a hole 43 for receiving the head of the automaton and the cross bar which encircles the waist of the figure and is provided with a draw-string 44.
