This linvention relates to toys in general and to a'V diving toy submarine in particular.

AThe primary object of the invention resides in a toyfsubmarine of a buoyant nature to normally floatuponuthe surface of'a body of water but which may be made to dive or submergebelow the surfaceuntil the same strikes bottom at which time it will automatically rise to the surface and which simu- `1'0 lates the actions ofa submarine war craft.

Another object of the invention is to pro- .vide a ltoy submarine which has an inclined passage or chute at thel forward end or bow thereof which is closed at its lower end byv l5 ,a door to block the passage of a weighted ball therethrough to cause the toy to dive bow first and entirely submerge, and a means automatically operable when the toy 4reaches bottom to :open .the door to releasev the weighted ball whereupon the toy submarine is free to return to the surface of the water under its own buoyancy. y

A furthervobject of the invention is the provision of a toy boat having an open ballast compartment in its underside which automatically fills with water when the body is placed therein to maintain Vthe .same on an even keel and prevent accidental capsizing A still further object is to providea toy submarine which is simple in operation so that a` child can operate the same, and from which much pleasure may be derived in watching the actions of the same. With these and other objects in view, the invention residesin certa-in novel construction and combination and arrangementv of parts, the essential features of which are hereinafter fully described, are particularly pointed outl in the appended claims, and are illustrated in the accompanying drawing in which Figure k1 is a side elevation of improved toy submarine on the surface of a body ofy water. y v Y Figure 2 is a similar view showing the same in a partially submerged condition and with a portionwbroken away in section.

Figure is a detail perspective view of the weight member. 'i g Referring more particularly to the' draw y ing, the reference numeral .10 designatesy my submarine toy in its entirety which includes a buoyant body 11 of a shape simulating` the general outline of a real subma-rineby having a conning tower 12 rising therefrom together with certain other like parts. `The bodyy or hull llmay be constructed of wood, metal orother buoyant material and has its underside cut-away at the stern as at 13 to accommodate a propeller shaft 14 having a propeller 15 thereon and which may be driven by `anyr suitable mechanism. "Therbody is providedI with a chamber 16 which open's'into the cut-away portion 1 3 through a recess 17,;and'which chamber and recessjare disposed belowthe waterline of the body so as to automatically lill up with waterwhen placed therein. The water fills the chamber lf--and serves asa ballast for the toy for preventing the same from accidentally tipping (over. p

rlhe body 11 is provided atfits forward end with an inclined passage or chute18, one end vof which opens through a .conning tower 12 whilethe opposite end terminates at the bow adjacent' the keel and which is normally closed by a hinged door 19, held in a lclosedpositionby a keeper 2O fixed to a flat bow lspring 21, which has one end fastened to the underside of the body and its free end extending downwardly below the underside of the body and rolled as at 22. The normal tendency of the spring is tohold'the keeper 20 in engagement with the door 19 to prevent accidental opening thereof.

' A' door 23 is hinged to the conning tower o5 'for' normally closing the top of the inclined ypassage 18.

' For useinVv causing theV diving of the submarine, I provide la spherical-weight 24 fixed to' one end of alength of cord 25, while the svg,

other end of the cord carries a float 26. The length of the cord is dependent upon the depthof the body of water in which the toy i is adapted to be submerged, for the greater` the depth ofv the body of water, the longer will be vthe cord.

In QprltQIl, A'Che toy submarine may be made to float upon the surface of thev body of water W as shown in Figures 1 and 4 of the drawing, but when it is desired tocause Y the same to dive, the door 23 is lifted and the.

weight 24 dropped into the inclined passage 18. As the weight rolls toward the door 19, the front end of the toy will gradually sink beneath the surface of the water and will,

@any the entire body downward, bow rst until the free end 22 of the spring 21 hits the bottom B which causes the flexing ofthe spring and in turn releases the keeper 2O from 4engagement with the door 19, whereupon the weight drops from the bQdy to the bottom B. By releasing the weight 2e, the

'buoyant nature of the toy will gradually cause the sameto, return to lthe surface ot .the watery e Y n The Wight 24 be retrieved as the float 26fremainsupen the surface.y The boat may new removed trein the water and the door 19 closed behind the keeper 2() wheres upon' the submarine is'again readyV for diving.
