Title: Improvements in Variable Speed Gears for Cycles, Motor Cycles and the like.
Inventor: ROSS JAMES EDWIN
IPC: B62M11/14
Filed: 1911-01-12
Granted: 1912-01-11
Abstract: 819. Ross, J. E. Jan. 12. Variable-speed epicyclic gearing.-A two-train variable-speed hub gear for cycles, motor-cycles, &c. is provided with a single fixed sun-pinion, the internal wheels of both trains and the carrier g of the second train being each formed with peripheral clutch teeth p to engage in turn a sliding clutch member q whereby motion is communicated to the hub. As shown in Figs. 1 and 2, the driving-member c carries the planetpinions n of the first train, and is connected to the internal wheel c<2> of the second train, the sliding member being arranged to carry oppositely-directed pawls s, t for engaging with the hub teeth c' and the teeth b<2> of the brakeoperating member, respectively. The pivot of the pawl t engages a slot b<3> in the clutch member, so that, when the brake is applied, the pivot moves under the tail of the pawl s and disengages it from the hub. Moreover, when the machine is wheeled backwards, the initial movement of the clutch member causes the pawl t to pass under the tail of the pawl s and so disengages it from the hub; the brake is therefore not applied. In a modification without brake mechanism, a ratchet clutch is provided between the driving-member and the carrier of the first train, driving connexion between the clutch member and the hub being effected by pins engaging longitudinal slots or by teeth or other means. A friction clutch, such as the plate or ring form of clutch, may be interposed between the member q and the hub, say, for a motor-cycle, the clutch being releasable for starting the engine from a pedal - driven sprocket-wheel. As applied to a motor-cycle, the gear is modified so that the direct drive is the highest speed, the driving - member being connected to the first internal wheel, and the carrier of the first train and the internal wheel of the second being connected together.

Title: Improvements in Regulating Electric Tensions.
Inventor: GROB HUGO
IPC: H02P9/00
Filed: 1911-02-02
Granted: 1912-03-04
Abstract: 2719. Grob, H. Feb. 4, 1910, [Convention date]. Exciting. -The voltage of a generator is regulated by shunting its field-winding or the field-winding of its exciter by a device which allows little or no current to flow through it below a predetermined voltage, but which offers little resistance to the flow of current when the voltage is exceeded. The exciting-current may be supplied by the generator or by a separate source, while an arrangement is provided whereby the tension across the exciting-winding is lowered when current flows through the regulating-device. In the arrangement shown in Fig. 2, the field-winding B is shunted by a device C and is connected to an auxiliary source F, F<1>, the circuit of which contains a resistance G. Under normal conditions, little or no current passes through the device C, but when the voltage across the terminals A, A<1> reaches a predetermined value; current flows through the device C, thereby diminishing the current through the exciting-winding B and consequently the voltage across the terminals A, A'. In a modification, the source F, F' is replaced by a resistance R, Fig. 4, placed in the load circuit, the resistance R being replaced by a resistance U in series with an artificial load T when the load circuit Q is open. In a further modification, the exciting-winding B is placed across one of the main brushes of the dynamo and an auxiliary brush. In the modification shown in Fig. 8, the dynamo is provided with a second commutator, while a battery forms the device C, a second battery C<1> being placed on charge. When the voltage across the load circuit Q reaches a predetermined value, a cutout Z operates to break the field circuit of the dynamo, when the load is supplied from the battery C in the manner described in Specification 14,059/07. In order that the device C may come into operation at a tension little above the tension between the points A, A', the resistance of the winding B must be small in order that the tension between the points X, D may be small. To decrease the tension between the points X, D, a series booster V, Fig. 9, is placed in series with the winding B, while the booster may be provided with an auxiliary winding Y connected between the points X, D. The device C may consist of electrolytic cells, mercury-vapour lamps, or a positively-driven dynamo-electric machine. Specification 12,153/93 is referred to.

Title: Improvements in and relating to Boat Launching and Stowing Apparatus.
Inventor: LEWKOWICZ ANTHONY JOSEPH
IPC: B63B23/04
Filed: 1911-06-08
Granted: 1912-03-14
Abstract: 13,695. Lewkowicz, A. J. June 8. Davits working in vertical planes move on a cam-shaped track so formed that different linear velocities are imparted to the extreme end of the crane while equal lengths of arcs of the track way are traversed. Generally, the construction is such that, at the end of the outward movement of the crane, the extreme end thereof moves in a descending path and this movement is assisted by the suspended weight. The vertical tracks a, adjustably fixed in athwartship slides z by studs b<4>, support cranes c which are moved on the track by recesses f<2> in a wheel f, Fig. 5, engaging with conical studs a', Fig. 5. The wheel f is operated from a crank t through bevel-gear and worm gearing. A double clutch r is arranged on the shaft q of the crank t, and is normally in a position to carry the crane outboard. At the end of that movement, a band brake h<1> is released from a barrel k and allows the falls g, g<1> to run off their common fall drum i. When the boat is to be raised, the clutch r is moved across to lock to the crank shaft q, a pinion p gearing with a hoisting gear-wheel l. The lower parts of the cranes c<1> carry thrust rollers f, Fig. 2, engaging the lower surfaces of the tracks and so positioned that, when the fall suspension joints a<1>, Fig. 2, pass the crest of the trackways, they are constantly in advance of the driving-wheels f.

Title: Improved Calling Circuit Arrangements for Automatic and Semi-automatic Telephone Exchanges.
Filed: 1911-06-14
Granted: 1911-10-05
Abstract: 14,144. Siemens Bros. & Co., [Siemens & Halske Akt.-Ges.]. June 14. Automatic exchange systems.-The operation of signalling - devices and of means controlling the release of the connector is conditioned by the failure of the ringing - generator to transmit current over a selected subscriber's line, owing to faults, defective contacts, &c. W h e n the connector wipers a, b, c have been stepped on to the terminals of the wanted line, the side - switch arms s<1> . . . s<8> are moved into the third position, and, if the selected line is disengaged, the test-magnet Y is energized over arm s<8>, and sends an impulse from interrupter U<1>, over contact 4, arm s<6>, and side-switch magnet S, moving the sideswitch into its fourth position. The ringing- generator Q now sends current into the selected line through the coils of a relay R and over the side-switch arms s<1>, s<2>. After an interval, the interrupter U<2> energizes the magnet S to move the side-switch into its fifth position, energizing the magnet L, which cuts off the ringing-current at contacts 9, 10 except during regular brief intervals when the slow interrupter U<3> breaks contact. Intermittent spells of ringing-current are thus continued until the called subscriber answers, whereupon, during the next non-ring- ing interval, the magnet Y is energized over contact 11, side-switch arm s<2>, the called subscriber's line, side-switch arm s<7>, and inductance D<r>, and energizes the magnet S to move the side-switch to its sixth or speaking position. Every time that ringing-current flows, the relay It connects a buzzer FS over contact 5 and sideswitch arm s<4> to a supplementary coil i on the line relay B, so as to send back a signal to the calling-subscriber. But if for any reason current does not flow when the generator Q is connected to line, then the relay R connects in at contact 7 a trouble signal AL, which may be common to a number of connectors, and leaves open a contact 12 which controls the release magnet M in the fourth and fifth positions of the side-switch, so that the connector is not released by the calling subscriber hanging up. This enables an attendant to locate the trouble indicated by the signal AL.
