Variable-speed gearing. -The driving and driven shafts 5, Figs. 2 and 3, are each mounted at one end in a framework 1, and at the other end in a frame 10 adapted to slide on the framework 1. Each of the shafts carries an expanding pulley 15, 16, made in two parts 17, 18. The part 18 comprises a dished plate fixed to the shaft and carrying a number of conicallyarraoged arms united to a hub. These arms interlace with similar arms on the part 17, which is arranged to slide on the shaft. The hubs of the parts 17 engage the frame 10. An endless rope or band 39 passes round the pulleys 15, 16 and round guide-pulleys 40, 41 supported in hangers 42 swivelled to the frame 10. Upon moving the frame 10, by means of a pivoted lever 12, one of the pulleys is expanded and the other contracted so as to alter the velocity ratio of the shafts. In another arrangement, each of the guide-pulleys 40, Fig. 6, is supported by a hanger 47, loosely engaging the frame 10 and provided with a leg 49 free to turn in a socket 50 in the base of the framework. The pulley is drawn downwards, so as to keep the belt in tension, by means of a spring 51 or weights. Preferably the sockets 50 are brought close together so that the pulleys are inclined. By this arrangement, the guide-pulleys are maintained in close alignment with the pulleys 15, 16. In a modification, both the pulleys 15, 16 are loosely mounted on the same shaft, and are formed with or connected to pulleys for receiving and transmitting the motion.

Title: Improvements in and relating to Brake and Clutch Mechanism.
Inventor: ARBEY CHARLES ALPHONSE
Filed: 1904-12-06
Granted: 1905-10-19
Abstract: 26,605. Arbey, C. A. Dec. 6. Dynamometers.-The brake device described in Specification No. 23,700, A.D. 1964, [Abridgment Class Mechanism &c.], is adapted for use as a clutch and may be combined with other forms of brake, clutch, &c. and used in dynamometers &c. Fig. 1 shows a combination of the multiple-disc device with a conical friction clutch. The clutch member G is fixed to the driving shaft H and is adapted to be engaged by the conical member E, which carries a series of discs D interposed between another series C carried by a part A splined to the driven shaft B. The clutch is held out of engagement by a lever L, and is forced into engagement by a spring I acting on the part A, a weaker spring K being arranged between the parts E, A. When the lever is released. to allow the parts G, E to come into engagement, slip takes place between the discs C, D until the full pressure of the spring I is exerted, thus allowing the speed of the shaft B to be gradually increased. In a modification, the conical parts E, G are so arranged that engagement takes place where the parts are moved apart. Fig. 3 shows a combination of the multiple-disc device with a friction clutch of the coiled-spring type. The part A fixed to the driving-shaft H carries a series of discs C interposed between a series of discs D carried by a cylinder E. A helix M, constituted by a double winding, is arranged within the cylinder E and attached at the centre to the driven shaft H. A conical part G<1>, loose on the shaft H, carries a tappet J adapted to engage either of the ends m', m<2> of the helix according to the direction of rotation. The part G<1> is forced into engagement with a conical part on the cylinder E by a spring I, and is held out of engagement by means of a lever L. Normally, the cylinder E rotates with the part A, and, upon the conical part G<1> being allowed to come into engagement with the cylinder E, the tappet J is brought into contact with the helix and expands the same into engagement with the cylinder ; the discs C, D allow slipping so that the speed of the shaft H is gradually increased. A frictional device other than the part G<1> may be employed for bringing the clutch into action. In the arrangement shown in Fig. 5, a jaw clutch is arranged in combination with the multiple-disc device. The part E is provided with a jaw E<1> adapted to engage a jaw G<1> splined to the shaft H, a lever L and controlling- springs K, I being arranged in connection therewith. The devices described above may be employed as brakes by fixing one shaft. Where a helix &c. is used, it may be employed to actuate another brake or for compressing a spring &c. to store up the energy absorbed in braking, this energy being afterwards utilized. The securing of one of the series of discs to a shaft &c. and the compression of the discs may be performed by distinct members, and also by other means such as springs, weights, &c., or by a centrifugal device.

Title: Improvements in Receivers for Wireless Telegraphy.
Inventor: THOMPSON WILLIAM PHILLIPS
Filed: 1905-05-22
Granted: 1905-06-22
Abstract: 10,708. Thompson, W. P., [Ges. f³r DraUlose Telegraphie]. May 22. Wireless telegraphy receiving-systems are provided with two wave-detectors of different degrees of sensitiveness, so arranged that means operated by the less sensitive detector disconnects the more sensitive detector from the receiving-system. In the arrangement shown, the two detectors control the same local circuit. The ordinary receiving- circuit comprises the inductance b, coherer c, condenser d, and relay g, controlling the local circuit of the Morse instrument h and the battery i. The additional receiving-circuit includes the inductance l, condenser k, battery o, detector m (preferably electrolytic), and relay n, which controls a local circuit containing a magoet p, the Morse instrument h, and the battery i. When waves of little energy are received, the coherer c controls the Morse instrument, but when oscillations of greater energy are received the detector m controls the Morse instrument, at the same time disconnecting the coherer c in order to protect it. This is done by the magnet p attracting its armature f, which is retained by a tooth q on the armature of magnet r. The coherer circuit can again be closed by energizing a magnet r in the transmitting-circuit or by other means. The contact n serves to disconnect the aerial a from ground when the transmitting-circuit r, s, t is being used.
