Title: Improvements in Cash Registers or Check Tills.
Filed: 1900-05-01
Granted: 1901-02-16
Abstract: 8046. National Cash Register Co., [Carney, T., and Lundgren, C.]. May 1. Tills.-In the type shown in Fig. 3, the keys are arranged in sets of nine, each with its own register, Fig. 4, and every key A is provided with an extension I from which a pin V extends externally. When the universal bar F, in the actuation of the apparatus, moves with the keys A, which have been depressed to indicate and register any particular transaction, the extensions I pass into vertical slots in the rocking frames Wand the pins V of the depressed keys into lateral slots b. Thus, by placing the pins V of each set of keys in succession positions, as indicated, the throw' of the frame W is made proportional to the value of the key depressed, and, by means of the rack X and, pinion E<1>, communicates a proportional movement to the first of the wheels Z of the register, with the return movement of the parts. The pinions E' are turned back, but the registers are not affected. This result is attained by connecting the pinions E' and the first wheels of the registers by clutches D', F' operated by levers G<1>, G<1> pivoted to a cross-bar L' ; during the up-stroke of the universal bar F, an extension arm Q', acting by means of a special cam face Q" on the lever O<1>, M', slides the cross-bar L<1> in one direction and engages the clutches, but in the return stroke the bar is slid back and the clutches disengaged. " Carrying " is effected on the registers in a known way by the pinions R<1> and scallop wheels S<1> mounted on a countershaft. To allow of zeroizing, the countershaft is mounted in a rocking frame U<1> which is thrown back by a cam A<2> on turning the register shaft B<1> by means of a key and bevel gear Z", Z<1> ; the wheels Z are loose on the shaft B', but have spring pawls which are picked up successively by a notch in the shaft B<1> and the wheels carried on to zero position. While the frame U' is thrown back by the cam A<2>, the scallop wheels S<1> are held against accidental displacement by engaging with the frame C<2>. The frame U<1> is held normally so that the carrying-pinions are engaged, by means of a pin on the plate E<2> pressed forward by the spring D'. A screw pin on the plate engages the cam A', and, when the shaft B<2> is being turned to zeroize the register, the plate is forced out and frees the frame U'.

Title: Improvements connected with Gas Lighting Torches.
Inventor: GLOVER JOHN GEORGE
Filed: 1900-06-08
Granted: 1901-03-30
Abstract: 10,515. Glover, J. G. June 8. Torches.-A torch in which the igniting-lamp is tilted and exposed for lighting incandescent street and other gas lamps without tilting the stick or holder, has the openings through which the igniting- lamp is tilted and exposed normally closed by a longitudinally or laterally - sliding screen, which protects the flame of the igniting -lamp from extinction while the torch is being carried from lamp to lamp. In the construction shown in Figs. 1, 2, and 4, the longitudinally - sliding protecting-acreen D is mounted upon a rod E, which is lowered by pressing upon the end J of a bell-crank lever or its equivalent H, and is restored to its closed position by a spring L as soon as the pressure upon the actuating -lever is removed. The lamp A is pivoted to the fixed part C of the torch, and a positive tilting movement is imparted to the lamp by a spring K, which may, however, be dispensed with by pivoting the lamp on one side of its axis, as shown in Figs. 5 and 9. A perforated protector R is provided for preventing the extinction of the flame of the lamp A by the explosion which occurs when the gas is ignited. In Fig. 5, the lamp A is mounted upon the laterally-sliding or rotary screen D, which is turned by a button M working in a slot N in the stick or holder I, the tilting movement of the lamp being guided by the curved edge of the opening in the fixed part C of the torch. In Fig. 9, the part C carrying the lamp A is caused t) slide longitudinally within the sleeve D to expose the igniting-flame, by pressing the upper end U of the sleeve D against the top of the lantern of the street or other lamp which is being lit.

Abstract: 11,257. Briggs, I. June 21. Circular knitting-machiness.-Relates to a method of fashioning stokings or other hosiery without varying the number of stitches in a course, and consists in using the tapered yarn described in Specification No. 16.995, A.D. 1898, on a flat or conical circular machine in which the needles can be moved to or from the centre. The needles N are carried in grooved and tapered holders B, which can slide in tricks in the needle bed. Projections b<1> work in grooves a<3> in the bed. Projections b' work in a groore e<1> in the cam plate. The cam plate is carried and can slide on a rotatable arm E. A screw F, engaging a nut d<1> on the cam plate, has a toothed wheel f<1>, which, as the arm E rotates, comes in contact with one of two projections h<1> or h', and so rotates the screw step by step and feeds the cams, and so the needle holders to or from the centre. The projections h<1>, h<2 >are on a slide adjustable by hand. In a modification, the needle beds rotate, and the screw is operated by a right or left-handed worm and worm-wheel driven from the main shaft by worm gearing. The Provisional Specification states that a ribbing-attachment can be used, in which the ribbing-needles are pivoted and moved nearer to or further from the centre with the frame needles.

Granted: 1901-09-07
Abstract: 15,965. Boult, A. J., [Miglioretti, Comte A.]. Sept. 7. Barometers.- Relates to electric apparatus for indicating whether an aneroid barometer is rising or falling. The indicator d works between insulated forks b and c, balanced at v and pivoted lightly between centres. A battery p has one pole connected to the oscillating armature l of two electromagnets g, h, and the other pole with the indicator d. The arms band c are in the circuits of the magnets g and h respectively, which terminate at contacts n and m respectively. In the position shown, should the arm d move downwards, it would make contact with the arm c, and thus complete the circuit of the magnet h, the contact m being closed. The armature i would then be attracted, move to the right, and thus break the contact m. In moving into the position i<1>, however, it would make the contact n in readiness for the next contact of the indicator d and arm b.

Patent GB-190106360-A (GB)
Title: Improvements in or relating to Internal Combustion Engines or Motors.
Inventor: BOULT ALFRED JULIUS
Filed: 1901-03-26
Granted: 1902-04-26
Abstract: 6360. Boult, A. J., [Chavanon, F.]. March 26. Gas and explosive-vapour engines.-A two-stroke cycle double-acting reversing engine receives compressed charges of air and gas, oil, or vapour and ignites them immediately the admission valve is closed, the governor determining the volume of the charge according to the load. The cylinder A has no clearance, and the engine may compress its own charges in a pump G, which delivers the air from the part 1 and the gas from the annular part K to separate reservoirs, whence they are admitted through pressure-reducing valves to the motor cylinders. The suction valves of the pump are automatically controlled by the pressure in the reservoir. Valve gear; igniting; reverving.-The admission valve at one end of the cylinder is operated by the same cam as the exhaust valve at the other. The cams operate levers s, s<1> attached to rods u; these in turn operate the exhaust valves through tappets S, S<1>, and levers g, and the admission valves through rods u<2> and levers f. The rods u, u' are joined by a catch which is tripped by a lever x under the control of the governor. The igniting - commutator T' or a tube igniter is also operated by the rods s u' directly the admission valves close. Another set of cams are slid into the path of the levers s, s<1> to drive the engine backwards. When the cams are shifted, a premature exhaust is produced at one side of the piston, and the exhaust is throttled on the other side, thus arresting the engine. A charge then enters, and is ignited.

Patent GB-190123416-A (GB)
Title: Apparatus for Automatically Supplying Water to Boilers.
Inventor: BOULT ALFRED JULIUS
Filed: 1901-11-19
Granted: 1902-03-06
Abstract: 23,416. Boult, A. J., [Automatic Boiler Feedwater Regulator Co.]. Nov. 19. Feedwater, controlling. -The supply of water to the feed - pump is stopped, or the pump is short - circuited, when water instead of steam passes from the boiler through an opening at the normal water level, advantage being taken of the difference in the physical properties of water and steam to actuate a controlling- device. Fig. 1 shows apparatus acting by the difference in temperature between water and steam. White the water level in the boiler A is below the normal, steam escapes by the pipe a', and, after being superheated by burners G, acts on a thermostat E by which the valve D is held open. The feedpump C then draws from the tank B, and supplies the boiler through the pipe c<3>. When the level rises sufficiently, water flows through the pipe a<1>, and, not being raised to such a high temperature as the steam by the burners G, it affects the thermostat in such a way that the valve D is closed. The supply of water to the feed-pump is thus stopped. The water from the boiler is returned to it by the pump F. Fig. 2 shows apparatus acting by the difference in the velocity of water and steam. All the while steam is passing from the boiler by the pipe o', the injector R acts to produce a partial vacuum above the valve S, which can therefore open to admit water from the tank B to the pump C. When, however, water passes, the injector ceases to act, and the valve S remains closed. The pump then returns the escaping water to the boiler. A relief chamber T and valve t prevent back pressure due to steam generated in the pipe c' from stopping the action of the injector. Fig. 3 shows apparatus acting by difference of pressure. In this cafe, a central tube is provided in the boiler, having perforations at the normal water level through which steam or water can escape. Steam passes through a pressure-reducing device C to a condensing-coil F in a casing through which the feedwater passes on its way to the pump K. Its pressure is thus reduced so that it is incapable of raising a piston I. When water, instead of steam, passes through the coil, its pressure is not reduced, and the piston I is raised and a valve J is opened, by which the feed-pump is short-circuited, the water passing back to the suction through the pipe Q. A small hole through the piston I allows water condensed in the coil F, while steam is passing, to pass to the pump with the feedwater. The application to the boilers of motor vehicles is mentioned.
