R. RAMSAY Dec. 8, 1953 TOY BOAT Filed Sept. 29, 1950 Inventor Raou? Ramsay 3f/MJ Attorney Patented Dec. 8, 1953 UNITED STATES PATENT OFFICE d t v 2,661,571 l l TOY B'OAT Raoul Ramsay, Cut Knife; SaskatchewamCanada Application September 29,E 1950, Serial No. 187,468

VThis invention relates to toys and more par- "ticularly to a liquid propelled toy boat.

said chamber consists of a cylinder within which .is disposed a spring loaded piston which causes the liquid to be expelled therefrom to propel the toy boat.

The primary object of the invention is therefore to provide a novel liquid propelled toy boat which may be adjusted to operate in circles or in a straight line or in reverse direction.

A further object is to provide means whereby the liquid is not permitted to escape while the chamber is being lled.

Still another object is to provide an adjustable rudder so that the device may be operated in a straight or curved line or in reverse direction.

With these and other objects in view that may appear as the description proceeds, the invention consists in the novel arrangement of cooperating elements as hereinafter more specifically set forth, claimed and shown in the accompanying drawing forming part of this application and in which:

Fig.l 1 is a side elevational view of a toy boat constructed in accordance with my invention;

Fig. 2 is an enlarged detailed view of the inlet to the liquid chamber.

Fig. 3 is a detailed view of the rudder;

Fig. 4 is a rear elevational view of the rudder;

Fig. 5 is a detail of the pump to fill the fluid chamber.

Referring more in detail to the drawing in which similar reference characters designate corresponding parts throughout the several views it will be seen the invention comprises a toy boat 5 having a hull 6 and a cylinder 'I formed within the hull.` The cylinder comprises a piston 8 mounted on a rod 9 and a compression spring I0, at the rear of the piston. The said rod extends through the rear Wall of the boat and is formed with a knob II by means of which the piston is brought back and the spring I9 compressed when the cylinder 1 is lled with liquid.

The liquid enters the cylinder by means of an aperture I2 normally closed by a ball check valve I3 to prevent the liquid from escaping therefrom when said liquid is under pressure.

The piston 8 is slidably mounted on the rod 9 so that when the cylinder is lled with liquid 5 Claims. (Cl. 46--95) l the rod may be pushed back to its original posi- 1 tion and held therein by means of a projecting i stud I3 formed on the rod which lits into an L-shaped groove I4 formed on a plug extension I5 formed integral with the rear wall of the hull. The liquid is expelled from the cylinder 1 by the piston, through channel I5a extending from the forward end of the cylinder longitudinally of the hull. The channel Ilia extends into a cylindrical extension formed integral with the rear end of the hull on which collar I8 is rotatably mounted.

A tube 20 having its upper end tted in the I collar I8 has a passage Il therethrough adapted to register with the channel lia when the tube is in a vertical depending position. A rudder I6 is rotatably mounted on the lower end of the tube 20 to swing about the axis of the tube and the passage I1 through the tube at its lower end communicates with the horizontal passage I9 in the rudder through which the liquid is discharged. Upon swinging the rudder upwardly, as shown in dotted lines in Fig. 4, the channel I5a and passage I1 are moved out of register which shuts oil' the flow of liquid through the rudder.

To steer the direction of the boat the rudder I6 is turned about the axis of the tube 20 on which it is rotatably mounted and if the rudder is turned from the position shown in Fig. 1, the liquid will be discharged from the passage I9 in a forward direction thus driving the boat in a reverse direction.

It is believed that the construction and advantages of the structure shown may be apparent from the foregoing paragraphs taken in conjunction with the accompanying drawings without further detailed description.

While the preferred embodiment of the invention has been disclosed it is understood that minor changes in the details of construction, combination and arrangement of co-operating parts may be resorted to within the scope of what is claimed withoutedeparting from the spirit of the invention.

I claim:

1. A toy boat comprising a hull having a pair of parallel longitudinal passages in communication at one end, a spring actuated piston mounted to reciprocate in one of said passages, the other passage being open at the rear end of said hull, means for retracting said piston, and means for introducing liquid into said passages, said piston when released operating to expel the liquid from said passages.

2. A toy boat comprising a hull having a 1ongitudinal bore, a, second bore parallel to said first mentioned bore and communicating therewith at one end, the opposite end of said second bore being open at the rear end of said hull, means for introducing liquid into said bores, a spring actuated piston mounted to reciprocate in said first-mentioned bore, and means for retractng said piston, said piston when released operating to expel the liquid in Vsaid bores from the open end of 'said secondementioned bore.

3. A toy boat comprising a hull having a 1ongitudinal bore, a second bore parallel to said rstmentioned bore and communicating therewith-at one end, the opposite end of said second bore extending into an extension iii'th'e ra' er'id f said hull, a rudder pivotally mounted on the rear end. of said hull having a passage Vtherethrough open: ing through the rear edge of the rudder, said second bore having communication with the pas- 'sage 'through said rudder, means for introducing liquid. into said bores, ,a spring actuated piston mounted in said first-mentioned bore, and means :for retracting said piston, said piston when -released operating to expel the liquid in said bores l through the passage in said rudder.

'4. A toy boat comprising a hull having a longitudinal bore, a second bore parallel to said first-mentioned bore having communication therewith at its front vend, an extension. on the rear end of said hull having a passage therethrough with one end in communication with the vre'ar 'end of said second bore, a collar rotatably mounted on said extension having an opening adapted at times to register with theVVV passage in the extension, a tube having one end tted in the opening of said collar extending radially from said collar, a rudder rotatably mounted on said tube to rotate about its axis. said rudder having a passage extending from said tube through the rear edge of the rudder, means for introducing liquid into said bores, a spring actuated piston mounted in said first- 'm'nti'hed b'r,r and ifieais' rtifating said piston, said piston lreleased loperating to expel said liquid from said bores and through the Tpassage of said rudder.

5. A toy boat comprising a hull having parallel longitudinal passages in communication at n'eendaiidldaptii to receive a liquid, a piston mounted to reciprocate in one of said passages, 'the other passage" opening through the rear end of said hull for admitting liquid into said passages upon movement f the piston in one direction,and a spring for moving said piston in the opposite directionuto expel the liquid from the open end of the other passageiwm M RAQUL RMSAY.
