Abstract: 751,828. Toy helicopters. KRAUTKRAMER, A., and KRAUTKRAMER [nee BERG], L., [trading as BERG KOMM.-GES., J.]. July 28, 1954 [Nov. 30, 1953], No. 22055/54. Class 4. A toy helicopter comprises a fuselage 1 supporting an upright rotatable shaft 3 to which a driving dog 4 and a flanged collar 5 are secured. A further collar 8, formed with a flange 9, and a removable screwed cap 11, is secured to the shaft 3 above the collar 5 and spaced therefrom by a gap which accommodates wires 7 constituting the spars of the blades. The inner end of each wire is bent upwardly at 13 to engage within a hole 14 in the collar 8 and the wire then extends along the leading edge of each blade, round the tip and back along the trailing edge to be bent forwardly at 19 and twisted round the root leading edge portion into an upwardly extending arm 15 terminating in a bend 16. Each arm 15 engages a slot 10 cut in the flange 9 and the inclination of the slot is such that acceleration of the rotor causes the blades to undergo lagging movements about the pivots 13 to cause the arms 15 to move in the slots 10 in a direction to increase the pitch of the rotor blades, which return to a normal negative-pitch setting when the rotor speed falls. To facilitate storage the blades may be folded one above another over the fuselage by springing the arms 15 out of the slots 10.

[Also in Group XXX] The difference of travel of the ropes of a grooved multi-rope driving pulley is measured by means of counters as an indication of the difference of tensions in the ropes due to differences of groove diameter. Single wheel device (Fig. 1).-In the grooves 1 of Koepe pulley 2 run single wheels 3, which are carried by frames 4 pivoted at 5 and are urged into engagement with the grooves by springs 6. The readings of counters 7 indicate the differences of travel due to differences of groove diameter, and therefor the differences of tension in the ropes. Counter 8 indicates the number of revolutions of the pulley 2. The counters work in only one direction of rotation. Double wheel device (Figs. 3, 4).-In place of each wheel 3 of Fig. 1, we have double wheels 3a, 3b. Each double wheel is pivoted at 14 and biased to bring wheel 3b into engagement with the respective groove 1 of pulley 2. Each wheel 3a is secured to and rotates with a shaft 11, the shafts 11 being coupled by universal shafts 16 to and driven by reference wheel 15 running in reference groove 15 of pulley 2. Scales on the wheels 3a, 3b indicate their relative rotation as a measure of the tension of the respective ropes. To allow for a relative rotation greater than 360 degrees, each wheel 3a carries a star wheel 22 and each wheel 3b carries a pin 25, the pin engaging the star wheel at each revolution so that the star wheel indicates the relative rotation of the wheels 3a, 3b, and therefore the rope tension. To avoid initial setting errors of the two wheels a certain frictional contact between wheels 3a and 3b is given by spring 18, 19, the wheels being separated by friction disc 17.
