My present invention relates to aquatic devices such as imitation fish and comprises a device of this type adapted to be propelled in liquid by lateral movement of parts thereof.

I One object of the invention is-to provide ax toy fish that can be automatically propelled in water by movements closely simulating the swimming movements of realfish.

Another'object of the invention is to provide in an aquatic device a novel combination of parts which may be usedto insure efiicient for:-

ward. movement in water of the device by suc-,

cessive relative'movements of articulatedparts thereof. I

A further object of the invention is to provide a toy fish that may be economically manufactured from relatively inexpensive materials.

I have found that an eificient forward movement in water or other liquid substantially simulating the swimming motion of a fish may be given to a device; such as. a toy fish, if about half of the device is made up or" a plurality of articulated sections and if means are provided not only to control the extentof lateralmovee ment of each section relative to each other and to the front half of the device but also-to so control the order of movement of each section as to insure successive movements of each section beginning with that adjacent the front half thereof. .Although toy fishes, have heretofore been proposedwhich were intended to Joe automatically propelled by lateral movement of one or of a plurality of sections, none; so faras I am aware, have been'so constructed as toyinsure the proper succession of motions required and above briefly ,describedfor efficient forward movement simulating the actual swimming mo:

showing the parts in displaced position.

a The toy mechanical fish illustrated in Figs, 1 to 4 inclusive is constructed of wood and com prises a head and body portion 1 and a plurality of tail sections 2 to 9 inclusive. The head and body portion 1 includes a right hand and left hand portions 1a and 1?) respectively which are. suitably secured together, when the fish is assembled as by a screw 10. Cooperating cavities within the head portions 1a and 1b provide a chamber 11 and a longitudinal central groove 12. ,Secured to the inner surface of portion 1a adjacent the rear thereof is a sheet of rubberized cloth or 'canvas 13 whichv extends rearwardly ,fiexible sheet 13. These slots are for reception andguidance of wires 16 and 17 which arosecured tothe end section 9 and are connected to opposite ends of therocker. arm 18 mounted in chamber 11 for horizontal movement about an axis 19. As shown best in Fig. 4 the depth ofthe slots.,15 vary, decreasing in magnitude from tions.2 and 3 the'end walls of slots 15'define curved surfaces 20 concave tothe surface. of

sheet 13. The variation in depth of the slots is provided for the purpose of taking up the slack in the wire when the tail sections are in either extremity of their range of movement and to assist in obtaining the proper sequence of -movements of the tail sections. This will be apparent from a study of Fig. 4 which illustrates in full lingwires at one extreme position and in dotted lines a subsequent position of the parts. With the tail swung fully to the left, as indicated, wire 16 lies along the extremities of the slots 15 and 'wire 17 within sections 4 to 9 lies along the surfaceof sheet .13 and forwardlyfrom the point ,A' in the plane ofthat part of the sheet 13 to which section 4 is secured. This position of mechamsm hereinafter described, section 2 and form an acute angle.

tions 4 to 9 will move first with section 2 and then with section 3 but no relative movement between successive sections will occur because the pull of the wire in each of these sections was in the plane of the portion of sheet therein. When the parts assume the dotted line position, a turning moment will now be exerted upon section 4 but not upon the remaining sections within whichwire 17 still lies upon the surface of sheet 13. The turning of section 4 about section 3' carries sections 5 to 9 therewith. Sections 5 to 8 inclusive are thereafter successively moved about each other in the same manner as above described for sections 2, 3 and 4. Section 9 does not move relatively to section 8 until the reverse movement of the tail is initiated at which time it swings over to its extreme position by the force of the water or other liquid in which the toy is propelled. This whole succession of motions which is initiated each time arm 18 is rocked from one toanother'of its extreme positions gives a powerful forward motion to the device and gives a most life-like appearance to the toy. -Attached to section 9'and extending rearwardly therefrom is a caudal fin 21 of celluloid or thelike, which, because of its relatively large area and also because of the powerful flipper movement given. thereto by the above described successive movements of the tail sections creates the major portion of the forward push upon the fish. f i

To insure proper operation of the tail sections as above described the depth of slots 15 should be so proportioned with relation-to the length of rocker arm 18 and'with reference to the relative angular movement permitted between adjacent sections by'the cut away portions 22 as to insure free lateral movement of the wires and to make provision for taking up the slack in the wires at each successive position of the tail sections.

In the particular embodiment of the invention illustrated, the means for rocking arm 18 include a crank 25 which is mounted for rotation about a horizontal axis. The arms of crank 25 One arm rotates in a vertical plane and the other has slidably mounted thereon a loop of wire 2 5a, the opposite ends of which are connected to the ends of arm 18. This arrangement .gives sufiicient lost motion between crank 25 and arm 18 to insure rocking of the arm fromone extreme position to the other twice for each complete "rotation of the crank. Crank 25 may be rotated automatically by any suitableywell-known means.

For example, as indicated in Fig. 2 the driving means maycomprise a heavy elastic 23 located in groove 12 one end of which is adapted tobe twisted by a winder'24 operablefrom the exterior of the fish and the other end of which is coupled to crank 25 to impart rotation theretoj Instead of the simple drivingmeans above described a coiled spring type of motor 26operable by a key 27-may be provided as indicated in Fig. 5, in which case the axis of crank 25 may carry a pinion gear 28 driven by a gear of the motor. 4

When the mechanical fish is of wood, as in the embodiment of Figs. 1 to 5 inclusive, it may be found necessary to weight portions of the fish not only to insure proper balance ofthe parts but also to prevent the fish fromfioating on the ,Fig., 1

" To increase the life-like appearance of the device celluloid or the like fins 29 may be secured thereto and eyes and mouth 30 can be painted on the external surface as indicated in Fig. 1.

In Figs. 6 and '7 a mechanical fish constructed of stamped metal parts is illustrated. In this embodiment of the invention the separate tail section 2c-9c inclusive are secured together and to the head portion 10 by vertical pins 31 about which their relative rotation occurs. To limit the extent of relative movement between the parts, cars 32 are stamped from the side walls of each section and bent inwardly to provide stops for the next succeeding section. A series of channels 33 carried by pairs of pins 31 by horizontally extending portions 34 of graduated length serve the purpose of the graduated slots 15 of Fig. 4 in guiding the operating wires 16 and 17 and in taking up the slack therein. It is ordinarily sufficient to provide channels in alternate sections only, as indicated.

The operation of the fish illustrated in Figs. 6 and '7 will be readily understood without further description as its operation is substantially identical with that of the device illustrated in Figs. 1 to 4 inclusive.

In making the device of metal, means may be required to prevent sinking in water and to bal-- ance the device properly. Such means may conveniently comprise sealed tubes 35 containing air and suitably positioned in the head portion and in one or more tail sections.

My invention has now been described with particular reference to its embodiment in toy or imitation fish of wood or metal. In each embodiment of the invention illustrated means including laterally'and longitudinally movable operating wires and articulated sections having predetermined range of relative lateral movement have been provided to insure powerful forward movement of the device by successive movements of the sections. In one embodiment of the invention free lateral movement of the operating ,wires was provided by longitudinal slots. In

the other embodiment of the invention illustrated horizontally supported guide channels provided the equivalent of the horizontal slots. These means for insuring proper forward propulsion in water or other liquid, could of course, be advantageously employed in aquatic devices other than toy fish and hence the appended claims, unless otherwise specifically limited, are intended to include any aquatic device with which the invention could be advantageously employed.

The term wires as used herein and in the appended claims is intended to include any flexible non-elastic means such as chains or cords.
