Patent GB-190012388-A (GB)
Title: Improvements in or relating to Mechanical Motive Devices for the Controlling Drums or Switches of Electrically Propelled Vehicles.
Inventor: BOULT ALFRED JULIUS
Filed: 1900-07-09
Granted: 1901-08-09
Abstract: 12,388. Boult, A. J., [Gill, E. R.]. July 9. Switches. - Relates to improved actuating-mechanism for electric controllers. The mechanism may be fitted in a casing adapted to be placed on the ordinary controller. It comprises a small electromotor which is started by the handle and drives the controller spindle through differential gearing brought into action by a brake controlled by electromagnets. A spring is fitted in connection with the gearing to return the controller in case of a stoppage of the current, or release of the handle. The actuator may be arranged to control a number of motors as on a train. Fig. 1 shows a sectional plan, Fig. 3 an elevation, and Fig. 10 a view of the actuator in position. The shaft 16 is provided with a socket 17, adapted to fit on the controller spindle. Mounted loosely on it is the worm-wheel 32 driven from the motor 45 by the worm 47. Above is a pair of wheels 31 and 26 having a different number of teeth, with which gear pinions 33 supported in bearings on the wheel 32. The wheel 31 is fixed to the shaft 16, and the wheel 26 is fixed to a brake-wheel 25, with which a band brake is adapted to engage. When the brake band is tightened, the wheel 26 is stopped, and thus motion is communicated to the shaft 16 through the wheel 31. The brake band is tightened through a toggle joint by swinging a lever 56 by means of a lever 69 connected to the armature of an electromagnet 66, which also serves to close a relay circuit. The band is also tightened by an electromagnet 59 and by the action of an arm 22 when the spindle is returned to its normal position. When the handle 7 is moved to an intermediate position to obtain half-speed, the motor circuit is closed, a crank on the handle spindle engaging a speciallyarranged slotted link. At the same time the magnet 66 is energized and the band brake tightened, and the controller is thus rotated until the double cam 37, 38 moves a rod 86 having two bearing-faces, and operates special contacts 80, 81 to open the motor circuit. A further movement of the handle to full speed makes another contact, and again starts the motor. Should the current fail, the magnets are de-energized and the band slackened, the spring 20 returning the controller to the off position. When the handle 7 is released, the circuit is opened, and the same action results. A dash-pot is arranged to prevent shocks when the spring acts. When it is desired to control a number of motors, as on a train of cars, the actuators are connected in parallel by means of a number of wires depending upon the number of '' speeds to be obtained.

Docks; caissons; sunken ships and objects, raising.- Relates to dry docks either for repairing vessels, as shown in Figs. 1, 2, and 10, or for constructing vessels, as shown in Fig. 22. In each case, the dry dock is constructed from a number of iron pontoons A, B, C, which are detachably secured together by bolts f. Each pontoon has blocks E, E', E<2> for supporting the vessel V, and is provided also with a pump e connected by jointed pipes d<3> with a boiler on a scow s, whereby water can be pumped either from the space between the vessel and the pontoon or from any of the chambers into which the interior of the pontoon is divided by narrow partitions. The pontoons are preferably of equal length, so that, when turned through a right-angle and coupled together, they can be easily towed. When repairing a vessel, half of the intermediate pontoons C are secured to the bow pontoon A and half to the stern pontoon B. They are then submerged, and are drawn together under the hull of the vessel by means of cables passing near the blocks E from the stern to the foremost half of the pontoons. An auxiliary rectangular pontoon may be provided for raising submarine objects, or for forming a dry dock by being placed at one end of a number of the ordinary pontoons. When part only of the vessel needs repairing, one or more of the pontoons may be employed, and a water-tight connection between the end pontoons and the vessel is made by means of the apron shown in Fig. 10. The apron is formed of two layers of planks e<4>, which are secured by bolts e<3> to metallic bosses e' on a bulkhead F fixed to the end pontoon. The planks are connected together by straps e<5>, e<6>, e<8>, and the planks of one layer break joint with those of the other, distance pieces f<3> being employed at the bends. The end portions B<3> of the apron are pivoted at f<4> to the middle part B<2>, and ropes i<1>, i<4> hold the parts in position. The inner edge of the apron is grooved to receive a hose-pipe packing f<2>, expanded both by internal springs and by fluid pressure, and a water-tight connection between adjacent pontoons may be similarly made. When constructing a vessel, pontoons of the modified form shown in Fig. 22 replace those above described. Near each corner of the pontoon is a hollow column D, provided with rings r, and sockets s for cranes G, and depressions o for receiving the supports D' of scaffolding D<2>.

Title: Improvements in or relating to Free Wheel and Back Pedalling Brake Mechanism for Cycles and the like.
Inventor: SACHS ERNST
Filed: 1903-09-08
Granted: 1904-01-07
Abstract: 19,378. Sachs, E. Sept. 8. Brakes clutches; driving- mechanism.--Relates to free-wheel and back-pedalling hub-brake mechanism for cycles and the like. In the form shown in Figs. 1, 4 and 9, the sprocket-wheel b is secured on a sleeve c provided with recesses d, in which are arranged rollers, balls, or the like e. The rollers are guided by a ring f having a screw-threaded extension, on which works a sleeve g. The hub a runs on ball bearings x on the sleeve c, and on the fixed cone i, to which is secured a split cylinder h carrying a brass or like brake ring m held in position by a rib k. A spring p, placed between the cylinder h and the sleeve g, produces sufficient friction to hold the rollers e in position either for forward driving, or for free-wheeling, and also allows the cycle to be wheeled backwards. When the sprocket-wheel b is rotated backwards, a conical edge on the sleeve g moves into, and expands, the split cylinder h, so as to brake the hub. A ring s, fixed on the axle, relieves the ball bearings from the axial pressure produced when the brake is applied, and a spring ring t holds in position the ring r and parts e, f, g when the hub is being taken to pieces. In the form shown in Fig. 6, the axially-movable sleeve and friction spring are replaced by a ring and inner coiled spring respectively, the ring being moved axially by means of teeth c<1> to apply the brake by back-pedalling. In a modification, the ring is in two parts which can engage together by ratchet teeth.

Granted: 1904-01-28
Abstract: 25,389. Bloxam, A. G., [Schoeller, A.]. Nov. 20. Magneto-electric machines.-To obtain proper sparking at starting and at slow speeds in a magneto-electric machine used for ignition purposes in internal-combustion engines for motor cars &c., the revolving armature is stopped for a short period of each revolution of the driving- wheel, and is then moved forwards rapidly through its inductively-operative position. The armature shaft W of the machine M carries a fast lever N and a loose driving-wheel A, rotated by the motor, to which is attached a recessed disc D and a weighted lever C. During each revolution of the wheel A and disc D, a spring F<1> draws the lever N and shaft W round until a spring-pressed catch K drops into the recess D' in the disc D to grip the lever N ; the spring F<1>, being thus extended, draws the lever N &c. round rapidly when the disc D again raises the catch K. The timing of the ignition may be varied, to regulate the speed of engine, by means of a lever H carrying the catch K and actuated by a suitable governor. When the normal speed has been attained, the above mechanism may be out out of gear by lifting the catch K either by hand or by the centrifugal action of the weighted lever C ; the engine speed at which the lever C acts is adjustable by means of the springs B, F<2>. Two or more recesses D<1> may be formed in the disc D, to obtain the increased armature speed at two or more inductivelyoperative positions. The arm C may act as a governor by raising the catch K, and thereby opening a switch in the ignition circuit to prevent ignition when the normal speed is exceeded.
