The present invention relates to fourwheel'ed trucks, and is particularly applicable to four-wheeled trucks the parts of which are in miniature and'constructed and combined as a toy-that is a substantial copy of standard construction. v
The principal object of the invention is to provide a novel apparatus for compressing air and piping the compressed'a-ir'to a receptacle for use, such, foninstance, as discharging a liquid in a continuous stream and as an-auxiliary object to design such apparatus, so that it may be readily applied to toys that closely resemble a standard fourwheeled truck without making it grossly apparent that the truck is a .toy because of some prominent feature that is foreign to standard construction. Accordingly, a feature of the invention comprises a toy fourwheeled truck constructionhaving meansfor holding compressed air for use,,an air-pump for supplying the holder with. compressed air mounted beneath a hood simulating, in location and construction, a standard motor for operating the air-pump, that depends from the front of the frame where the engine starting crank is located on power driven trucks. Other ob jects of the invention are toprovide a novel toy pumping engine apparatus simulating a standard fire fighting truck for utilizing the air in the holder for discharging, a liquid in a continuous stream, and to provide a simple but reliable mechanism forraising and lowering a tower for the liquid discharge hose of the toy pumping engine apparatus.
To the accomplishment of these ob ects, and such others as may hereinafter appear,
the various features of the present invention relate to certain devices, combinations and arrangements of parts fully set forth hereinafter, the advantages of which will be readily understood by those skilled in the art.
The various features of the present invention will be best understood from an inspection of the accompanylng drawings illustrating the preferred form of the invention as applied to a toy, in which:
Figure 1 is a view, in perspective, showing a standard motor pumping engine truck in miniature and the connections from the imitation starting crank for placing the liquid in the supply tank under pressure;
Fig, is a detail, in perspective, showing the hood tipped back to expose the air located beneathuthe hood; and v Fig. 3 IS a detail, in perspective, showing pump ' the mechanismifor raising and lowering the water tower for'the liquid discharge hose.
The-toy pumping engine truckillustrated in the drawings comprises a standard fourwheeled", motor truck infminiature provided with a frame, a hood. 5, an open cab- 6, a radiatori', a body 8,. and. a handstarting crank 9. All theseparts 'simulateclosely the design of a pumping engine'truck mounted one commercial Packard chassis.
Mounted on the .truckibetween the body 8 and cab 6 is a holderforv compressed. air herein showniasa combined water and pressure tanklO" having a filling plug ll'through' which the tank. may be partially filled. with water. Suitably connected to the bottom of the tank 10 is a flexible hose; 12 provided with a cock 1'3 and terminating in a discharge nozzle 14.
" Inorder that the tank 10'may be supplied with air under pressure to forcibly expel the waterfrom thetank through the hose, 12 and out of the discharge nozzle 1a in a continuous: stream when the'cock 13' is opened, an air-pump 16 is provided conveniently hidden and supported'on the frame 4 beneath the hood 5. To this end the frame a carries a bridge 15 upon which an air-pump 16 of the reciprocating piston typei's mounted. The piston ofthe' pump is reciprocated by a pistonrod 17 which is pivotallycon,- nected to a pin 18 eccentrically mounted upon a disk 19. The disk 19 is secured to the rear end of a shaft 20 journaled at its rear end in a cross: girder 21 below the bridge 15. The forward end of thexshaft 20 is journaledat 22 in the forward end of the frame 4. The hand-startingcrank 9 is mounted on the end ofthe shaft 20 where it projects through the frame 4. By rotating the crank 9 the shaft 20 may be revolved to operate the air-pump 16 through the connec: tions described. The air injected by the airpump 16 is conducted through a" flexible hose 23 to the space above the water level in the tank 10 and is there compressed.
In order to make the air-pump 16 easily accessible, the hood 5 carrying the radiator 7 and the bell 24 is provided with a pair of up standing ears 26 which are pivoted on siml;
ears 26 carried by the dashboard 27 of the cab 6. With this construction the hood 5 may be tipped from the position of Fig. 1 to that of Fig. 2 to expose the air-pump (see Fig. 2).
If the toy is to simulate a chemical pumping engine, as those skilled in the art will recognize is within the scope of the invention, the hose 12 will be unsupported throughout its length so that it may be coiled within the body 8 when not in use. WVhen it is desired that the toy simulate a pumping engine of the water-tower type the hose 12 is carried on or within a tower 28 supported at its base on a stand 30 carried by the frame at the rear of the body 8. The tower 23 and stand 30 are pivotally connected by a transverse pin 29.
In order to provide mechanism for rais ing and lowering the tow-er 28 on its pivot 29 it carries a bracket 31 to which the eye end of an eye screw 32 is pivoted. The other endof the screw 32 threads through a nut 33 which rotates on the flat surface of a transverse yoke 34 secured at its ends to the opposite sides of the body 8 and having an opening to loosely. receive the screw 32. The nut 33 is in the form of a circular flanged plate the upper peripheral edge of which is toothed to convert it into a wormwheel for engagement by a worm 35 carried by a shaft 36 rotatably mounted in cars 37 on the stand 30. The shaft 36 is provided with an outboardhand-wheel 38 having a crank pin 39 laterally projecting therefrom. Rotation of the hand-wheel 38 revolves the worm 35 and the worm-wheel or nut 33 thus causing the screw 32 to travel vertically and to either raise or loWer the tower 28 as the hand-\vheel 38 is turned one way or the other.
In using the toy, as a pumping engine, the
cock 13 is first closed and it is seen that the tank 10 is partially filled with water. The hand-crank 9 is then actuated to drivethe air-pump 16 in order to compress the air in the space within the tank 10 above the water level. lVhen suflicient pressure has been built up in the tank 10 the cock 13 may be opened whereupon the pressure will cause a continuous stream of water to be discharged through the nozzle 14.
It will be clear to those skilled in the art and with the general object of the present invention in view, that the compressed air in the holder may be utilized other than to discharge liquidand that changesmay be made in the details of structure, the described and illustrated embodiment being intended as an exploitation of its underlying essentials the features thereof are definitely stated in their true scope in the claims herewith.
