Description
April 6, 1954 c. l. SPRINKLE HYDRAULICALLY-OPERATED TOY Filed July 9, 1952 IN VEN TOR.
CZ VDE SPF/IVKLE BY fi/f A TOP/V5) Patented Apr. 6, 1954 UNITED STATES ATENT' OFFICE 1 My invention relates to improvements in toys, especially aquatic toys that are adapted to float upon a body of water and relates more particularly to an improved hydraulically-operated motor for propelling and operating such a me-.
chanical aquatic toy.
An object of my invention is to provide an aquatic mechanical toy that is automatically animated and propelled by hydraulic forces.
Another object of my invention is to provide a mechanical toy having movable members with means for operating those members hydraulically.
Another object of my invention is to provide an aquatic toy with an hydraulically-actuated motor for applying pulsating propulsion forces thereto.
Another object of my invention is to provide a simple and, inexpensive hydraulically-actuated motor for use in operating or propelling a toy.
The foregoing and other objects of my invention will become apparent from the following specification taken in connection with'the accompanying drawing where:
Figure 1 is a side view partly broken away of an animated duck to which my invention is applied;
Fig. 2 is a front view of the duck;
Fig. 3 is a schematic diagram illustrating the operation of the duck;
of Fig. 1; and
Fig. 5 is a sectional view taken on the line 5-5 of Fig. 1.
Referring to the drawing, there is illustrated an animated duck employing my invention. This duck includes a hollow body member l0 having a rounded breast portion l2 and a tapered tail portion I4. The seat l6 of the body member [0 is thickened to provide a stablizing weight and the remaining walls of the body member are of more or less uniform thickness, the entire body member enclosing a cavity I 5. Intermediate the front and rear ends of the body member there is provided an upwardly extending tubular neck portion l8.
A hollow head member in theshape of a ducks head is movably connected to the neck portion I 8 by means of a transverse pin 22, the head being pivoted for rotation about a transverse axis to provide a nodding action. The head member 20 comprises a main head portion H comprising a cavity 23 and including an upper bill part 24. A lower movable bill part 22 is pivotally secured to the main head-portion 2| by means of a trans- Fig. 4 is a sectional view taken on the line 4-4 verse pin 26 arranged on the main head portion 2| at the jaw position, the two bill portions thus being arranged for relative movement, simulating a quacking action. The lower bill part 22 is secured to a rigid member 28 that extends into the head cavity into a position above and opposite the neck 18. This rigid operating element is provided with an upwardly extending operating or arm element 32 directly opposite the rear portion of the neck l8. An opening 34 is formed in the operating. element 32 in alignment with the central opening in the neck portion [8.
A tail member 40 is attached to the outer end of a shaft 42 journalled in the tail portion I4 and extending into the body cavity I5. The shaft 42 is inclined downwardly at an angle of about 45 and is provided at the inner end with a transverse operating element or arm 44 extending upwardly at an angle of about 45 so that movement of the arm 44 causes the tail member 40 to rotate, thus simulating a wagging movement.
A discharge, or exhaust, fitting or pipe 54 extends horizontally and is secured within an outlet 58 arranged in the tail portion of the body member, being supported in fixed position by an inclined transverse partition 60. The duck is so designed and its weight so distributed that it normally floats'up to a waterline indicated by dashed lines in Fig. 1. With the tail member 40 and the head member 20 well above the waterline and the outlet 58 below the waterline.
The propulsion and animation of the duck are produced by means of a very simple hydraulicallyoperated motor. This motor comprises a flexible tube 50, such as a thin-walled rubber tube, one end of which is connected to a supply fitting 52 and the other end of which is connected to the exhaust fitting 54. The supply fitting 52 is rigidly mounted along a vertical line in the lower wall portion IS, the outer end of this fitting being connected to a hose 56 through which water is supplied continuously under pressure during operation.
The flexible tube 50 is looped about the shaft arm 44 and also aboutthe neck pivot pin 22, being threaded through vertically spaced holes 62 and 64 in the partition 60 mounted within the body portion as well as being threaded through the neck portion l8.
The portions of the tubing extending through the holes 62 and 64 are substantially parallel,
being supported in fixed positions and resiliently constricting the rear portion 66 of the tubular member adjacent the shaft arm 44. Likewise, the portions of the tubing extending through the 3 neck 18 are substantially parallel, thus resiliently constricting the upper portion 68 of the tubular member within the head cavity 23. The two constricted portions 66 and 68 are thus pinched together substantially closing the passage through the tubing. The rear loop Hi so formed encircles the arm M and is adapted to rotate that arm about the shaft 42 as the loop vibrates horizontally, about the fixed parallel parts thereof which thusv act as a pivot for the loop 10. The upper loop 12 so formed extends through the aperture 34 and is arranged to strike.
the operating arm 32 as this loop vibrates back and forth about a horizontal axisnear the fixed parts thereof which thus act as a pivot for the loop 12.
In effect, the two constricted portionsfifi and 68 of the tubing 50 operate as hydraulicallyoperated valves. The opening of each of these valves decreases when the pressure on the upstream side thereof is reduced and enlarges when that pressure is increased, thereby causing the flow of water through the tubing to pulsate. As each of the constrictions decreases, hydraulic pressure. increases on the upstream side of the constriction, thus swelling the tubing slightly. Finally, when this pressure becomes great enough the constriction is enlarged permitting water to pass rapidly through or past the constriction, thereby relieving the pressure on the upstream side. thereof. When thi'spressure is relieved, the constriction is. again reduced causing the pressure to be increased again on the. upstream side thereof. The repeated rise and fall. of pressure and the repeated corresponding fall and rise of fiow rate causethe corresponding loop to vibrate about .the fixed parallel parts referred to above.
With the arrangement described; when water under pressure is supplied through the hose 56 the rear loopHl vibrates in a horizontal direction. about a vertical axis and the upper loop 12 vibrates forward and backward about. a horizontal axis. The vibrating action of the loops 10 and 12 causes the tail 40. to wag and both the main head portion and the lower bill part 22 to oscillate, simulating a. very natural animated effect. l
The oscillation of pressure in the loops T6 and 12. and the resultant vibration of parts of the loops. occurs continuously, whilethe flow of water into the supply tube 56. is maintained. At the same time, the repeated opening and closing of thevalves B and 68 causes the flow of water through the tubing to pulsate, thereby causing the discharging waterto apply pulsating forces to the duck( One of these forces acts along the axis of the exhaust fitting and the other along the axis of the supply fitting 52. The exact nature of the resultant action varies somewhat with the positions of the axes of the fittings relative to the center of percussion and the center of gravity of the duck. Generally speaking however, as a result, the duck is propelled forwardly and rocked by intermittently applied forwardly directed and upwardly directed forces.
In practice, the supply tube 56 may be connected by means of a fitting 80 to a faucet 82 and the duck placed in a partially-filled bathtub 84. To restrain the movement of the 'cl'uck;.a weight 88 is attached to the supply tubing 56; thus permitting the duck to make random excursions on the surface of the water within a limited range.
In practice, in the manufacture of the duck the body member In is formed of two parts Illa and mo and the wan member so is formed uni- 4 tary with one of these sections, as indicated in Fig. 4.
A stopper 86 may be arranged in a port 88 near the bottom of the body member to facilitate emptying water from the cavity l5.
From the foregoing disclosure, it is apparent that I have provided a novel improved animated aquatic toy embodying many novel features which are adaptable as well to many kinds of toys other than the specific toy hereir'i' illustrated and described. Thus, the feature of animating the head and tail may be applied to the animation of other relatively movable body elements of a, toy animal. Likewise, the hydraulicallyoperated motor may be applied either to actuate other moving parts or to propel other kinds of aquatic toys lt will, therefore, be understood that my invention is not limited to the specific embodiment thereof illustrated and described herein but that it may be applied to other kinds of devices. It will also be obvious that my inven tion is not limited to the. specific embodiment illustrated and described herein but is capable of a variety of mechanical; embodiments. Various changes which will now sugest themselves to those skilled in the art may bemade in the ma terial', form, details of construction, andarrangement of the elementswithout departing from the principlesof my invention; Reference is therefore to be had tjotheappended: claims to ascertain the scope of theinvention.
