Description
Jan. 29, 1957 w. E. SCHEITHAUER ANIMATED SUBMERSIBLE TOY Filed June 14, 1954 United States Patent 2,779,131 ANHVIATED SUBMERSIBLE TOY Walter E; Scheithauer, San Francisco, Calif. Application June14, 1954, Serial,No.. 436,412.
6 Claims. (CI; 46-92) Thisinventionrelates to. submersible toys and ispartieularlyconcerned. with. a. hydrostatic device inthe. form of an animated, figure, such as-a fish, which is. adapted to float at or near the. surface when, immersed in a body of liquid, and. which descends through. the liquid and executes a movement, of a gripping; member, thereof, such as the jaw of the. fish, upon,the applicationof pressure. to the. liquid.
Amusement. devices of the Cartesian diver type: are known. They are constructed as compressible bodies to displace a variable quantity of liquid; was hollow, bodies that. admit. or expel liquid to alter the weight of the body in accordance withthe prevailing pressure sov that the weight of thebody is slightly less than the weightv of the liquid displaced, thereby when the. pressure is. low and. slightly greater than the. weight of the: displaced liquid when. the, pressure is high. Among suchknown devices, are. those. in; which the center of gravity. is altered. in relation to, the; center. of buoyancy upon contraction or influx of liquid to cause. the devices to alter their. inclinations. simultaneously. with their upward. and downward movements.
While prior toys of thistypehave been amusing, they have not been animated beyond undergoing. a. minor change in shapewithout physical contact with the walls of the. container which holds the liquid. or other niechanical. connections. One of. the attractions of such amusement devices is their ability to perform movements. of external gripping or clamping members that are. more or less mystifying and are eflectedin alifelike andpuzzlingmanner. with no visible connection between the controlling or actuating element and the submersible toy. Further, such prior devices performednofunction beyond moving through the liquid and their sole attractionresided in their aspect; they would be more interesting. if they were capable of performing. some. mechanical action or function, such as seizing or gripping and. transporting an object, especially if such. function were successfully accomplished only occasionally. so.as.to challenge the skill or perseverence. of a person operating the toy.
Itjs an objectof the invention to provide a submersible toy-havinga body and a movable gripping, member. which will; descend and ascend through a body of liqiud. while efiectinga motion; between the body and the gripping memben.
A further object is to provide asubmersible toy of the type-described'which can perform a physical action, such as-engaging or graspingan object within-a bodyof liquid. A- specific object is to provide a diving toy in the shape ofan animate creature, such as a fish having a movable jaw, which can descend, open its mouth, hold an object such as a pebble, imitation pearl or a figure of a marine animal that isusually eaten by fish, ascend with said object in its mouth, and release or 'disgorge the object at any desired level at the will of an operator, thesaid object resting on the bottom ofthe container that holds hce 2. the liquid. or being. otherwise supported; e. g., by a thread.
In summary, the submersible toy according. to. the. invention. includes ahollow body having anopening covered by a flexible. diaphragm that. is substantially flat, at low liquid pressure and, is, adapted, to be. forced inwardsinto said opening upon an. increase in. the. liquid pressure, said body having a movable, grippingmember an. element of which is in. engagement with, said; diaphragmfor movement therewith,,where.b.y. said. appendage. is. actuated by the deflection of the diaphragm. The gripping member may be biasedby gravity and/ or by a resilient member for movement in one. direction and by the diaphragm for movement in the opposite direction. The said element engaging the diaphragmis usually a lever protruding from the movable appendage. and bearing against the diaphragm. By locatingthe saidop'eningand flexible diaphragm away from the center of buoyancy the. inward movement of the diaphragm causes. a shift inthe center of buoyancy of. the body whereby the body alters its inclination when the pressure. inflthe liquidQis; increased. The. weight of' the toy isv such, that the weight. of. the liquid displaced'thereby exceeds the weight. of the toy when the diaphragm is in its. outer position but is. less than the weight of the toy. when the diaphragm. is. deflected inwardly.
Consideredbroadly,,the.invention, includes also a my device as described in the foregoing paragraph. wherein thefeature of locating the opening; andl'diaphragm. away from the center, of buoyancy is omitted;
The invention will be described'in detail with. reference to the accompanying; drawing forming a part of this specification and"showing,two preferred" embodiments. by way of illustration, wherein:
Figure l is. a vertical sectional view of a container holding liquid in which the toy is immersed, parts being shown in' elevation;
Figure 21 is, an elevation of the toy on anenlarged scale;
Figure ,3 is. a transverse section taken on the line 3f-'--3 of Figure 2; and
Figure 4 is an elevation of a modified construction, parts of the head and movable jaw being shown in section.
Referringto Figure lin detail, 1 is the surfaceof'a body of liquid contained in a transparent, glass-walled pressure vessel 2 having a domed. closure 3" sealed hermetically by a gasket 4 and pressed downward "by a screw 5 having threaded engagement. with a strap 6 which engages the annular bead ofthe vessel. A compressible bulb 7"communicates' through a-tube8$ with the interior of the vessel. When the-bulb 'is contracted the pressure of the air above theliquid and, hence; the pressure withinthe liquid are increased; releasing the bulb reducesthe pressure. The pressure can be brought to and held at a desiredvalue'by compressing'tife bulb partially. The vessel contains objects, such as imitation pearls 9wand blocks 10, to. be engaged by the t'oy;
The animated. toy itself isin;.the:form 'of-a fishhaving a rigid, hollow body 11 made. of sheet: metal, plastic material, or the like,.and,having an amplehol'e rlzgsituated at the bottom, and near the front, somewhat: forwards from the center of gravity of the toy. This: hole: is covered by an impervious, flexible diaphragm; or. them? brane 13. The hollow body is, hermetically closed1- to contain a fixed. quantity of air which may: be at' atmosr pheric or at some other pressure. Although not. essen. tial to the invention, it. was found convenientto attach the flexible diaphragm 13 by forming it as a closed bag having only one open end 14.and'insertingthebodyll into the bag'with the'fr'ont end innermost... The. bag is advantageously made ofelastic'material'such as rubber and is circumferentially slightly smaller than the body so as to engage the body snugly and elastically. The bag thereby forms a cover for most of the body and aids in sealing it, whereby the covered parts forwardly of the end 14 need not be of liquid-tight construction. The bag may be suitably colored and decorated with a pattern including fish scales.
The body carries certain external immovable appendages representing parts of a fish, such as a tail 15, a head 16, and a dorsal fin 17, which are secured in any suitable manner. In the embodiment shown in Pig ures 2 and 3 the tail is integral with or permanently fixed to the rear of the body 11 while the head, to which the fin 17 is integral or permanently fixed, is a hollow body made of sheet material engaging the covered body flatly at the rear of the head and held in place by a thin connecting strap 18. This strap may be integral with or permanently fixed to the head, extend rearwardly in close proximity to the back of the body, and fastened to the tail, as by crimping the extremity about the tail at 19. Other arrangements for attaching the head may be used. The head extends forwardly from the body 11 and provides a downwardly directed edge shaped as an upper jaw. The head has a pair of holes 20 (one on each side) situated well to the rear but forwardly of the part of the head that lies flatly on the body to function as sockets for outwardly extending projections 21 of the movable lower jaw 22.
The jaw 22, which constitutes the movable gripping member, is shaped as an upwardly concave shell the rear part of which fits within the head at the holes 20 and the front of which presents an upwardly directed edge conforming to the shape of the upper jaw. The front may be directly beneath the front of the head to hold an object by a biting or clamping action; this action is not, however, essential, and the lower jaw can be slightly shorter so that objects are held only within the mouth, resting on the bottom wall of the jaw 22. The lower jaw has an integral arm or lever extending rearwardly beyond the transverse axis of the pivots 21, the rear extremity of the arm being inclined upwards to engage the membrane 13 at the center of the hole 12. The arm is shaped to engage the membrane while in the outer, substantially flat condition assumed when the liquid pressure is low with the jaw closed. The pivots 21 are situated well to the rear of the center of gravity of the jaw 22, whereby gravity tends to lower the front of the jaw. In addition to or in lieu of this positional relation a resilient member, such as a weak tension spring 24, which may be concealed within the head and jaw, is connected toward the rear of the pivot axis to bias the jaw toward open position. The stiffness of the spring 24 is such that the force of the membrane 13 against the arm 23 overpowers the spring, holding the jaw closed until the membrane is deflected into the hole by liquid pressure. Pins 25 are mounted immovably on the lower jaw.
The weights of the head, jaw and tail are such that the center of gravity is beneath the center of buoyancy when the fish is immersed in horizontal position as shown in solid lines in Figure 1. Further, the entire weight of the fish is slightly less than the weight of liquid displaced thereby at low pressure, which may be atmospheric pressure. When the bulb 7 is squeezed the pressure within the vessel 2 is increased and the membrane 13 is deflected into the hole 12, causing a slight compression of the air within the body 11. This decreases the displacement of the fish sufficiently to cause it to descend. Because the decrease in liquid displacement occurs at the hole 12, which is to the front of the center of gravity while the fish is horizontal, the center of buoyancy is shifted slightly toward the tail; this causes the head to descend in relation to the tail. The inward deflection of the membrane further permits the end of the arm 23 to rise, whereby the tension spring 24 contracts and the jaw opens. The
5. resulting condition and position of the fish while diving are indicated in dotted lines.
When the lower jaw engages an object 9 or 10 the bulb 7 is released, thereby decreasing the liquid pressure; this permits the membrane 13 to return to its outer, substantially fiat position. This return movement has the three consequences of increasing the displacement so that the fish ascends; of shifting the center of buoyancy slightly toward the head so that the head rises until the fish is almost horizontal; and of moving the end of the arm 23 down so that the jaw is closed. When the jaw closes an object 9 or 10 is seized and held, provided the fish was at the correct position in relation to the object at the instant that the bulb 7 was released. The object may be held in either of two ways: Objects of suitable outline or texture, such as the blocks 10, can be clamped between the front part of the head and the lower jaw with a biting action, while either type of object can be scooped up and be held within the mouth, simulating a swallowing action. The object can be released at any time, such as prior to ascent or after partial or full ascent to the surface 1 by momentarily squeezing the bulb 7, which causes the mouth to open and close. This gives the appearance of a fish disgorging the object.
It was found that only very small dense objects such as imitation pearls can be held in the mouth without making the fish relatively heavier at the nose. To permit the fish to ascend in the horizontal position or with the head slightly raised the object should have density that is only slightly higher than that of the liquid, preferably with a specific gravity above 1 and less than 1.2, e. g., a spongy body with a specific gravity of 1.1.
Because the horizontal location of the fish cannot be controlled directly and the horizontal movement is mainly that induced by the fin surfaces while the fish is descending or ascending, the fish will only occasionally be in a position suitable for seizing an object; it is therefore necessary to release the bulb 7 at the opportune moment to pick up the object. The device can, therefore, be used as an amusement device that requires a certain degree of skill and patience to lift the object from the bottom of the vessel.
It will be appreciated that numerous changes can be made in the dtails of the toy without departing from the scope of the appended claims and that the toy may be given the form of animate creatures other than fish. Similiarly, the movable gripping member need not be an organic part of the creature but may be in the form of an implement, e. g., a clamshell bucket held by a human figure.
Certain variants are shown in Figure 4, wherein like reference numbers denote parts described for Figures 2 and 3. This embodiment differs in the construction of the head and movable jaw and the arrangement for attaching the head. The fish includes a hollow body with a ventral opening covered by a flexible bag and having an integral tail, as before. The head 16a is attached without a dorsal strap and has, instead, an internal strap 13a the extremity of which is bent down, perforated and split to form an ear 26 that has a snap or resilient engagement with a support pin 27. This pin is permanently fixed to the front of the body 11 and may have an enlarged head. The membrane bag 13 is impaled on this pin before attaching the head. The lower, movable jaw 22a is wider than the head to fit on the outside of it and the pivot pins 21a in this case extend inwardly. The jaw is attached to the head by spreading the rear portions of the jaw resiliently and releasing them to cause the pins to enter the socket holes in the head. The resilient spring 24 is omitted in this embodiment.

A submersible toy fish according to claim 5 including resilient means connected between said jaw and head to urge said jaw toward open position in opposition to said memberane, said resilient means being weaker than the force of the membrane, whereby the jaw is closed when the membrane is in said substantially flat condition.
