Title: Improved Objective for Cinematographic and like Projection.
Inventor: BREARD ALFRED EMILE EDMOND
Filed: 1903-02-16
Granted: 1903-05-07
Abstract: 3633. BrÚard, A. E. E. Aug. 4, A.D. 1902, [date applied for under Patents Act, A.D. 1901]. Magic-lanterns.-The invention relates to lenses for projection. a b is an object and a' b<1> its image projected on a screen by a system of lenses d, e, f, g, g<1>. The first two are fixed while the others move. The focal length of the lens f is equal to the focal length of the combined lenses g, g<1>. The lens f and the pair of lenses g, g' each describe circles about axes parallel to the optical axis of the lenses d, e, but on opposite sides of it and equidistant from it, so that, once in a revolution, the optical axes of all five lenses concide. When this occurs, the lenses are moving in the same direction, so that the rotations are opposite. In the result, the image of a b moves in a straight line on the screen, gradually increasing in brightness as the lenses f, g, g<1> approach coincidence and then fading away. By suitably moving the object, its image can be kept fixed. Figs. 4 and 5 show a system, suitable for obtaining dissolving views, in which several lenses f and a corresponding number of pairs g, g<1> are carried by discs revolving between fixed lenses d, e, which are large enough to cover two or more of the others. The two Figures show the arrangement in different phases.

Abstract: 10,486. Sydenham, A., and Shaw, W. T. May 6. Driving mechanism ; motor cycles. -In a change-speed gearing for motordriven velocipedes, a chain - wheel a, Fig. 1, which is driven from the motor, is formed with a sleeve to which is secured a toothed wheel d. The sleeve is mounted on ball bearings on a sleeve e, which is mounted on ball bearings on a fixed axle f. A disc g, formed integral with the sleeve e, together with a drum j, carries a number of studs h, h<1>, on which are mounted pinions i in gear with the wheel d. A chain-wheel n for transmitting motion to the road wheels is secured to the drum by the studs or bolts h, h<1>. The drum j is formed with an internal conical friction surface, a corresponding surface being formed on a drum o fixed to the frame of the machine. A double-ended cone m, m<1>, arranged so that it can be brought into engagement with the conical surfaces on either of the drums, is provided with teeth p permanently in gear with the pinions i. When the cone m, m<1> is out of contact with the drums, the chain-wheels a, n and consequently the motor and the road wheels can revolve independently of each other. When the cone m is in engagement with the drum j, the parts are locked together and rotate as a whole, and, when the cone m<1> is in engagement with the drum o, the wheel n is driven at a slower speed than the wheel a through the epicyclic gearing ; by allowing slip between the clutch surfaces, the speed of the wheel n may be further varied. In order to operate the cone m, m<1>, the cone is connected to a tubular piece r by means of a circle of balls engaging races in the piece r and the cone. The end of the piece r is screw-threaded to engage a nut t carried by a lever u, and has cut-away parts so that it can be passed through apertures in the drum o to prevent rotation. A spring q is arranged to force the cone into engagement with the drum j ; by operating the lever u, the cone call be moved out of engagement with the drum and into engagement with the drum o, a notched sector &c. being provided to retain the lever in the required position. A ball bearing is arranged between the end of the sleeve e and the abutment for the spring q. In place of the cone clutch, spring rings m, m', Fig. 6, may be employed to clutch the drums o, j, when required. These rings are split and are mounted on a drum p<1> secured to the annular toothed wheel p of the epicyclic gear. One end of each of the rings abuts against a lug w<1> on the wheels, and the other ends are adapted to be engaged by the wedge-shaped ends z, z<1> of a forked lever x. This lever is coupled by pin-and-slot connections to the piece r, and may be moved so that the ends are out of engagement with the rings, or so that the ends engage one of the rings to press it into frictional engagement with the corresponding drum. Belt or toothed gearing may be employed in place of chain gearing for transmitting the motion.

Abstract: 22,246. Gibbs, C. Oct. 15. Electric railways and tramways, signalling on; stopping engines and trains; controlling and locking signals ; crossing-gate signals ; signalling approach of trains.-Consists in the employment of a rail insulated into sections, each section being adapted to be put in circuit with the insulated main by a switch which may work in combination with the signals. A switch lever a in the cabin b operates a switch which closes the circuit between the supply cable c and the third rail d. This switch lever is normally locked in the 'off' position, and is only capable of operation when released by the signalman at the cabin k in advance, in which a switch o is provided. When this is closed, current passes through an indicator q and a relay magnet r at the cabin b, thus closing a local circuit, operating the electromagnet t, and releasing the catch v.! If the signalman at the box k desires that the train should proceed to his starting-signal j, he puts the 'home' signal h to the 'all right' position and supplies current to the section f by the switch m. The train cannot proceed to the section n until the catch v is released by the signalman in the next cabin in advance. The gaps g between the sections are placed some distance before the signals in order to give the driver sufficient time to draw up. If required, indicators can be fixed at suitable positions such as crossings to show whether any section is alive, and also notice may be given to workmen when the rail is to be supplied with current.
