Relates to a particular construction of cipher, and to a cryptograph and a type-writer for use in writing or translating the cipher messages. The principle of the code is that two alphabets are employed, one for the letters of the message and the other for the signs or letters to represent them in the cryptogram, which are shifted relatively to one another according to some predetermined system after each letter or sign is written. Fig. 6 shows a plan of a type-writer for use in writing cryptograms according to this system. Two bars or frames C are employed beneath the right and left hand keys, each provided with projections F which act upon the arms of two conico-circular racks D secured to the shaft B. The cylinder B' is formed with slots in which are adjustable slide blocks arranged to regulate the movement of the double-armed lever b<2>, the backward extension of which enters the slots. The cylinder B<1> is rotated by suitable mechanism, so that the lever b' enters each slot in turn. Two drums A, X are employed, each provided with as many hammers s as there are keys, and connected by the rack Y. On depressing a key, the rod E lowers the levers h<1> and b<2>. The finger b<3> turns one of the racks D<1>, causing the drum X to rotate to an extent governed by the position of the slide block in the particular slot of the cylinder B' in which the lever b<2> happens to be.

Title: Improvements in Apparatus for Measuring a Supply of Electricity.
Inventor: PRICE WILLIAM ARTHUR
Filed: 1898-11-23
Granted: 1899-11-18
Abstract: 24,727. Price, W. A. Nov. 23. Quantity meters.-An electric motor is geared to a counter, and is supplied with driving-current from any convenient source through a switch O<1> ; this is closed or opened by small movements of a magnet C, which tends to turn in one direction under the action of a stationary conductor H carrying the current to be measured, and in the opposite direction under the action of a conductive disc G on the motor spindle A. The speed of the motor thus varies slightly about a mean speed proportional to the current to be measured. In the particular form shown in Fig. 3, the conductor H is a straight strip radial to the spindle A, and the movable magnet C consists of two strips connected by a non-magnetic yoke D and magnetized by being situated between the pole-pieces B of a large stationary magnet, not shown. The parts C, D, contact-arms O<1>, and a balance weight D' are supported near their centre of gravity by a single point K. Electric connection with the arm O<1> is effected by a point L on the yoke D touching a stationary spring F. Screws M, N are provided for fixing the movable parts for transport. A capacity and resistance in series may be connected across the motor, to prevent sparking. A wind shield may be placed between the disc and polepieces. In a modification, the pole strips C are arranged with free ends on opposite sides of the axis, those on one side embracing the disc G only, and those on the other the current conductor, which is coiled into a flat spiral. In another modification, the pole-pieces and yoke C, D are replaced by a movable magnet pivoted on two points, the stationary magnet being dispensed with. Instead of opening the motor circuit, the switch may short-circuit the armature, or introduce additional resistance into its circuit, to reduce the speed of the motor.

Abstract: 14,913. Lake, H. H., [Puttkammer, K., and Orthmann, F.]. July 19. Signals, time-alarm.-Relates to clock mechanism for operating time-alarm signals in factories &c., for automatically switching-in a workmen's tell-tale apparatus at any desired times, for switching-off an electric-lighting circuit, or for other similar purposes. Fig. 1 shows the apparatus adapted for closing the circuits L, A of a signal bell and a tell-tale apparatus, respectively. The circuits are normally broken between the contact springs d, d', which are engaged by the pins f<3> g<3> on the levers f<1>, g<1>. The hooked ends g' of the levers g<1> rest on the twelve-toothed ratchet-wheels h, which are rotated once every hour by the clock train a, b, c. The lever f<1> of the circuit L is normally supported by the weighted lever k, and the corresponding lever of the circuit A by the notch m' in the lever m, so that they hold the springs d' clear of the springs d. The disc T, driven from the clockwork, is graduated into five-minutes divisions, and is formed with two or more series of holes L', corresponding to the number of circuits to be controlled, and to the divisions on the disc T. When a circuit is to be completed at any desired time, a plug l is inserted in the corresponding hole L', and this plug, by releasing the lever k or m from the lever f<1>, permits the hooked end f<4> of the lever f<1> to drop into the recess between two teeth of the ratchet-wheel h, and so release the spring d<1>, which completes the circuit, while the shorter lever g<1> is still supported on the adjacent tooth. When, by the movement of the wheel h, the lever g<1> also falls into the recess, the spring d is also released and the circuit broken. Fig. 4 shows an additional switch for breaking the circuit S of an electric lamp. The circuit is made by operating the plunger n, which rotates the weighted three-armed lever c until the arm o<1> completes the circuit between the contacts e', e<2>, the lever o being locked in this position by the pin m<2> on the lever m engaging in a notch in the arm o<2>. When the lever m is operated by a plug on the disc T, the lever o is released and the circuit broken.
