Locks, permutation; stud-and-eye fastenings; fastenings, magnetic.-In a permutation lock in which the bolt is blocked by discs, the bolt is actuated for unlocking by a magnetic key and for locking by a non-magnetic key. The figures show the invention applied to a fastening in which a slotted stud 3 on one member 2 is secured in a recess 4' by the engagement therewith of a sliding piece 4 on a member 1. The piece 4 is prevented from sliding to release the stud 3 by a magnetic bolt 5 engaging a hole 6 in the piece as shown in Fig. 1. To release the bolt 5, the discs A, B, C, have to be correctly set by means of the shaft 8 and its rigidly attached dial 10 to aline soft-iron pieces a, b, c, behind the bolt 5. These pieces rest in correspondingly shaped holes in the discs A, B, C, and are of the same crosssection as the bolt. If a magnetic key is now inserted into the key-hole 14 in the disc 10, its attraction draws back the pieces a, b, c and with them the bolt 5, whereupon the member 4 can be operated to engage or release the stud 3. The bolt 5 is shot back into the hole 6 in the member 4 by inserting a non-magnetic key 12 into the hole 14, and is blocked by disengaging the combination of the rotatable discs A, B, C and 10.

Title: Improvements in or relating to gear-changing apparatus
IPC: F16H63/46
Filed: 1921-07-15
Abstract: 187,317. Ruck, Sir R. M. July 15, 1921. Controlling variable-speed gearing.-Controlling- means for step-by-step variable-speed gearing consists of a main lever 81, Fig. 1, having two motions about a ball joint 82 and adapted to operate gear-moving bars 73, 74 selectively, this lever 81 being so connected to a bar 25, Fig. 2, reciprocated by the power of the engine as to be actuated thereby only when the automatic portion of the device is purposely brought into action. This bar 25 is the " main slide " described in Specification 112,480, being thrust to the right or left by continuously revolving cams 27, 28 when locking-pawls 31, 32, Fig. 3, are released and thrown upwards by cam mechanism 44, 51, 52 and trigger levers 39, 40, Fig. 7. A bar 57, which can release these triggers alternatively, is connected by a bell-crank 61 to a " change-rod " 63, Figs. 1 and 11, the upper end of which is connected to a lever 64 having two push-knobs 67, 68. By depressing these knobs alternatively the main slide 25 is thrust by the engine one way or the other. The slide 25 engages a lever 86, Figs. 1 and 2, which carries a pin 85 projecting through a boss 84 upon the lever 81, so as to be able to actuate that lever in a fore-and-aft direction. To make a selection, the lever 81 must be thrust transversely through a gap 78, Fig. 8, in a partition 77, so as to engage either of two gear-moving bars 73, 74. This is done from the automatic control gate 66, Figs. 1 and 10, by an "index rod " 91. The rod 91, which turns on a pivot 92, is connected through levers 93, 94 so that a transverse movement of a knob 69 on the lever 64 in the gate 66, Fig. 10, is accompanied by a transverse movement of the lever 81 through the gap 78. The levers 93, 94 so connect the lever 81 and rod 91 that a fore- and-aft movement of the lever 81 is also accompanied by a fore-and-aft movement of the lever 64 in the gate 66, so that the position of the knobs 67, 68 with reference to figures 1, 2, 3, R on the gate indicate what speed is in use. A speed change may be earried out from the handle 83 of the lever 81. If power is to be used in making a change, a knob 67 or 68 is depressed, releasing one of the triggers 39, 40, when one revolution of the cam shaft 21 brings the gear to neutral. At the same time the main clutch is disengaged by a Y-shaped lever 122 as described in Specification 112,480. Further pressure on the knob with or without lateral movement in the gate 66 causes the cam-shaft to throw over the slide 25 carrying with it the lever 81 and selected rod 73 or 74. During such speed change the engine may be throttled down by an arrangement of lever 105, Fig. 11, wires 107, 108 and throttle lever 109. To prevent the reverse being thrown in inadvertently, a pivoted guard 110, Fig. 8, is provided obstructing the movement. This guard is connected by a rod 113, Fig. 1. to a spring pedal 115, which must be depressed before a car to which the invention is applied may be driven backwards.
