Definitions

  • This invention' relates to a toy which enables a peculiar optical illusion to be produced.
  • crank arm In the .path of a rotary drive, constructed for example like a crank arm, an obstacle is arranged which would have to be cut throu h or severed during the further turmngof t e crank drive.
  • the crank arm In order to simulate this impossible effect, the crank arm is provided with a drive Whichrotates the crank arm very rapidly in the opposite direction by means of a spring motor and brings the crank arm be hmd the obstacle.
  • crank arm may be constructed as a sword in the hands of a fakir.
  • the end of the obstacle which is referably arranged so that it can be uHed out of the device so as to 2 convince t e'observer of its resence, may likewise carry the head of a fa ir.
  • this toy it is possible to produce the impression that the sword passes through the neck of the head on the stacle without 2 any apparent damage or passage in the neck of the head. It is evident that the toy can be constructed in a great variety of models.
  • An embodiment of the invention is trated by way of example in the accompany in% drawing in which ig. 1 shows in front elevation a dial of a 'toy constructed in the shape of a watch with a hand-shaped crank arm and a simple pin projecting as obstacle.
  • Fig. 2 shows the construction of the crank Fig. 6 is a central vertical cross section through the toy with the driving mechanism in the osition shown in Fig. 3.
  • Fig. shows the drivin mechanism in the position of Fi 5, views in the same direction in which t e elements in Fig. 1 are shown for the position of the elements shown in F i 3.
  • crank arm 1 is constructed according to Fig. 1 in the shape of a hand and according to Fig. 2 as a sword. Its shape is immaterial.
  • the crank arm 1 is keyed on a shaft 2 which is rotatable by means of an operatin lever 6.
  • a pin 3 extends transversely t rough'the entire device parallel to the shaft 2 as shown in Fig. 6.
  • This pin 3 is mounted in a bore 4, as shown in Fig. 1, so that it can be removed to convince the observer ofits presence. It therefore also extends through a lass pane which is preferably arran ed in ront of the toy like a watch W glass. in ig.
  • crank arm 1 is,'however, only apparently moved in the direction of the arrow 30 from the radius a to the radius 6, that is transversely throu h the pin 3 (F i 1) or through the head of t e fakir (Fig. 2%.
  • the crank arm 1 or the sword is very rapidly moved by a driving mechanism, which will be hereinafter described, in the direction of the arrow 31 to the other side of the obstacle, so that the optical illusion is reduced that the crank arm 1 (Fig. 1) or t e sword (Fig. 2) passes transversely through the obstacle.
  • This mechanism comprises, according to Figs. 3 to 7, a toothed wheel 7 keyed on the shaft 2.
  • This shaft carries on its front end the crank arm or hand 1 and on its rear end a locking arm 8 projecting from an eye.
  • the locking arm 8 bears either against the right or left side of a pin 9 arranged below the axle 2 according to whether'the crank arm 1 is situated on the one or other side of the in 3 in the osition shown in Fig. 1 or Fi .7.
  • he toothe wheel 7 meshes with a toot ed 1 sector 10, which rotates around an axle 11 l arranged above the shaft 2 as near as possible to the edge ofthe case 25 of the toy.
  • the crating lever 6 is rotatably mounted on this axle 11.
  • the operating ever 6 is, as shown in Fig. 3, bifurcated at its end adjacent the axle 2 and forms two arms 28 and 29.
  • a spiral spring 12 is wound around the axle 11, the ends of this spring bearing against the above mentioned Karts so that a kind of spring motor is formed.
  • the driving direction of the spring motor owing to the arrangement above described and illustrated in Figs. 3 and 6 is always contrary to the winding direction of the operating lever 6. To enable the winding of the spring motor, it is held by a locking device during the shifting of the operating lever 6.
  • the above described abutment pin 9 and the locking arm 8 already described serve for effecting this locking.
  • the release is effected by one of two projections 17 on the arms 28, 29. These projections act on forks each having two arms 13 and 14 and they are arranged symmetrically one at each side of the shaft 2.
  • the arms 14 are slotted so that the locking arm 8 can pass therethrough.
  • the two locking forks 13, 14 are mounted on pivots 20 and 21 and each one is pressed in upward direction by means of a spring 15.
  • the springs 15 are clamped at one end in blocks 22 and 23 res'pectively.
  • the spring motor provided with the spring sector 10 is situated, as shown in Fig. 6, in a plane parallel to that ofthe operating lever 6 and the arms 28,29 of this lever.
  • spring 12 is situated between the arms 28 and 29 and has bent ends engaging in the slot 27 in the toothed sector 10 so that the spring is compressed between one arm of the operating lever and one end of the slot 27.
  • the shaft 2 is held by the arm 13 .j'gainfltheacfionofthespringlfiandliberof oneof the two locking forks with the aid of the locking arm 8, as clearly shown in 3.
  • the fork shown on the right of Fig. 3 is oscilla'hd' so that its arm 13 moves downw ates the locking arm 8 which rotates in the direction of the arrow 31 from the position shown in Fig. 4 into that shown in Fi 5, coming into contact with the other side 0 the abutment pin 9. Consequently, the shaft 2' with the crank arm '1 rotates precipitately in e the direction of the arrow 31 into the position shown in Fig. 5.
  • a toy comprising in combination an arm, an obstacle in the path of rotation of said arm, a spring motor operatively connected to said arm to precipitately .rotate said arm from one side of said obstacle to the other, an oscillatable operating lever to energize said motor in each direction of movement, a shaft carrying said arm, a
