Title: Improvements in hand and foot propelled vehicles
IPC: B62M1/12
Filed: 1938-05-30
Abstract: 515,317. Hand and foot propelled cycles. BRUYNZEEL, J. P. May 30, 1938, No. 16076. Convention date, May 28, 1937. [Classes 136 (ii) and 136 (iii)] In a bicycle propelled both by the hands and feet, the steering wheel is mounted in a pivoted frame carrying the two driving - mechanisms coupled together, the arrangement being such that the turning moments of the two sets of driving - forces tending to rotate the pivoted steering frame about its axis are balanced, so as not to affect the steering. The front steering wheel 3 is mounted in a steering frame 8 provided with two forks 16, 17 and rotatably mounted in a head tube 15. Pedal cranks 9 drive the front wheel 3 through a chain 19, and rotary hand-cranks 10 drive the sprocket of the pedal gear through a chain 18, the crank handles being used for steering. In order to balance the turning moments of the driving forces about the steering axis, the cranks 9, 10 on the same side are out of phase, and the hand cranks project laterally to a greater distance than the pedal cranks, so as to balance the greater thrust exerted by the feet. A seat 4 and a back-rest 5 are connected by strong fabric, which is held in the required angular position by a stretching- device 7.

[Class 39 (i)] [See also Group XI] Luminescent material such as phosphorescent zinc sulphide is excited to emit light by a variable electric field and is disposed on the inner face 7 of a gas-tight, transparent enclosure 1 of pear-shape with its height equal to its width. The enclosure 1 is very highly evacuated so that cathodic phenomena and probably also ionization are absent. The traces of gas inevitably remaining in the enclosure may be air or neon. The field is produced by connecting electrodes 2, 3 to a high-frequency source. One electrode 3 may be of tin foil on the outside of the enclosure 1 and the other electrode 2 may be internal as shown or external, or both electrodes may be metal plates between which the enclosure 1 is placed. Earth may be used as one electrode by resting the enclosure 1 on a sheet of water or the enclosure may be metallized internally or externally to form electrodes. Several electrodes of one polarity may be used. During the evacuation of the enclosure, a high-frequency current is applied to the electrodes. The Specification as open to inspection under Sect. 91 comprises also arrangements in which the enclosure is only partially evacuated. This subject-matter does not appear in the Specification as accepted.

Switches dependent on the ionization of gas.- A heavy-current relay comprises a vapour apparatus of the rectifier type, the anode of which is provided with a metal covering, the load current flowing between the anode and the cathode being interrupted, at will, by electrically connecting the metal covering with the cathode through a resistance or through a. source of electromotive force. In the construction shown, the alternating source m in the circuit II which is to be interrupted feeds a light arc between the anode a surrounded by the sheet-iron sleeve s and the mercury cathode k in the vacuum vessel g. The sleeve s may be closed by a sieve-like device o. A separate source of current b maintains an auxiliary arc between an igniting-anode z and the cathode k for the purpose of permanently exciting the cathode. The cathode and the iron sleeve are interconnected by a circuit 1 containing a switch r and a resistance or a source of electromotive force. When the switch r is closed, the flow of current in the circuit II is instantaneously stopped. The polarity of the source of electromotive force n in the controlling-circuit I may be varied to influence the controlled circuit II, in accordance with the changing polarity of the current source n.
