As shown, the gear lever 1 has a lower ball end 2 engaged in a pot-shaped rubber or synthetic plastics bearing 3 retained in a journal pin 4 serving as a guide for a shift tube in the usual manner, the lever 1 being connected to a support 6 by synthetic plastics shear pins 5, the arrangement being such that if the lever 1 is loaded by a heavy axial thrust from above, the pins 5 will shear and the bearing 3 will deform and separate from its mounting so that the lever 1 can be displaced downwardly into the position shown chain-dotted by a small axial force or by gravity. In a second embodiment (Fig. 2, not shown), the gear lever (7) is retained in the support (9) by a spring-loaded ball lock or detent (8) which may be released by a large axial force on the lever (7) such that it can be displaced downwardly as before. In a further embodiment of Figs. 3 and 4 (not shown), the lower part (21) of the lever (7) is of cylindrical shape flattened on two sides and terminating in a ball (21a) positioned in the journal (22) for the shift-tube (23), spring-loaded detent plungers (25) engaging elongated grooves (26) in the flattened part (21), the grooves (26) extending longitudinally of the lever sufficiently to permit lifting of the lever 7 against the bias of a spring 28 for engagement of reverse gear, and having sloping ends 33 whereby again if the lever (7) is subjected to a heavy thrust or blow from above, the spring-loaded detent plungers (25) will be cammed back by the sloping ends 33 of the grooves so that the lever can be displaced downwardly as before. The lever may be restored to its original position simply by lifting it back to its correct position.

Title: Improvements in and relating to the reception of submarine sound signals
IPC: G01S1/72
Filed: 1920-07-10
Abstract: 149,325. Signal Ges. Jan. 25, 1917, [Convention date]. Subaqueous audible signals.-In a receiver comprising, for example, a microphone coupled to a diaphragm, the combined structure gives a resonance curve of the form shown by the full line, with peaks at frequencies N1, N2. These frequencies correspond to the independent resonance frequencies n1, n2 of the microphone and the diaphragm, but are more widely separated, the difference being greater the closer the coupling. The invention consists in making the modified peak-frequency N2 of the diaphragm agree with the signal frequency, whereby it is stated that comparative freedom from shock-excitation is obtained, without undue loss of sensitiveness, as compared with working at the frequency N1. The resonance frequency of the microphone should be higher than that of the diaphragm, and the resonance of the diaphragm should be more highly damped than that of the micropnone. The microphone may be combined with an oscillatory structure, such as a tuning-fork, or may be replaced by an electro-magnetic system.
