Title: Improvements in Adding Machines.
Inventor: BABINI LOUIS
IPC: G06C7/08
Filed: 1912-11-22
Granted: 1913-11-06
Abstract: 26,890. Babini, L. Nov. 22. Adding - apparatus ; selecting denomination; differential mechanism. - A key - set and operated adding-machine, comprising a single bank of keys and a travelling carriage on which is mounted the totalizer, is provided with means whereby the spacing of the carriage from one denomination to the next is effected in two steps on the first of which the numeralwheels are advanced and on the second the actuating - parts a r e returned to their normal position. Each key-lever 3, Fig. 1, is connected by links 10, 31 to corresponding toothed segments 9 adapted to rotate an elongated drum 18 when a key is depressed. On the spindle 19 of the drum is mounted a ten-toothed mutilated master-actuating wheel 20, which in the normal position has the mutilated part adjacent to the totalizer-wheels 21, which are mounted on a shaft 22 in the movable carriage. The wheels 21 are rotated by an amount depending on the key depressed and on the number of teeth of the corresponding segment. At the end of its stroke, the segment strikes a cross-bar or yoke 15 secured to bell-crank levers 13 pivoted on a spindle 8, and thereby raises a yoke 16, attached to arms 14 and adapted to raise an arm 60 mounted on a rack 37 and thus swings the rack backwards to release a stop 43 on the movable carriage, which is thereupon drawn to the left by a spring motor until it engages a stop 44. In this position, the hubs of the totalizer-wheels 21 are opposite the wheels 20, and when the depressed key is released the master actuating- wheel 20 and associated parts will return to initial position without affecting the totalizerwheels. The yoke 15 is held forward by a notch in a lever 24, and is released therefrom by a pin 30 on the wheel 20 depressing the end of the lever 24. The yoke then returns to normal position and a spring 40 returns the rack 37, a tooth 42, Fig. 2, thereof passing through a notch in the stop 43, which will be moved to engage the next tooth of the rack. The " 0 " key-lever 6 when depressed moves the carriage one denomination to the left by raising the yoke 16, and a spacing-key operates the arm 60 directly to move the carriage. The stops 43, 44 are mounted on a spring-arm 46 and can be raised to space the carriage fpr a second item by means of arms 52, which are operated on the depression of corresponding rods 54, whereby the carriage is released from its rack until a stop 53 engages the end of the depressed rod 54.

Annular boilers; feed-water, supplying.-In a heating-installation in which combustion products are circulated by means of an injector, normally operated by steam, but provided with means for supplying compressed air for starting the draught, the water supply and compressed air for starting are both taken from the same vessel. The boiler f surrounds the grate g. Fuel is supplied from a hopper a, and the air supply is regulated by means of a perforated cone h with a hit-and-miss arrangement. A removable grate can be inserted between the cone h and the boiler to allow of the grate g being cleared. Air is drawn through the fire and forced through the heating system by an ejector l. The boiler is connected by pipes m, q with a tank n containing water and compressed air. The pipe m extends to the bottom of the tank n and supplies water, and the pipe g opens at the top of the tank and supplies air. The construction of the ejector l is shown in Fig. 2. A rod l<3> controls the orifice of the ejector and is moved by the pressure of the working fluid on a disk l<2>. As it rises, it lifts weights l<4> in succession, its motion being thus controlled.

Granted: 1914-05-07
Abstract: 10,918. British Thomson-Houston Co., [General Electric Co.]. May 8. Residual gases; bulbs; filaments; leading - in wires. - A tungsten or other metal filament of closely-coiled or other concentrated f o r m , large diameter, or both, is surrounded by an inert gas of low thermal conductivity, such as nitrogen, carbon monoxide, argon, or mercury vapour at a considerable pressure, say 50-760 millimetres of mercury when cold. The bulb may be of such form that blackening only occurs on parts not in the path of the main illumination. The gas is carefully dried by phosphorus pentoxide, and the bulb by prolonged and intense heating during exhaustion. It is stated that nitrogen combines with tungsten vapour, but not with the filament. A tungsten filament 10 mils. in diameter can carry 8 amperes at 0À7-0À8 watts per candlepower, and a coiled filament of 20 mils. diameter about 20 amperes at 0À4 watts per candlepower. The filaments may be squirted or drawn. Lamps with thick filaments may be connected in series. Large bulbs are preferred; in consequence of convection, blackening only takes place on their upper parts. A coiled filament 10 near the lower end of an elongated bulb may be carried by long thick wires 8 of wrought tungsten forming continuations of the leading-in wires. If the filament is of plain V-shape, the bulb may be narrow and taper slightly towards its upper end. Spherical lamps with depending V-shaped filaments may be made for use in various positions. Specifications 3988/78, 6193/82, 18,968/99, and 9250/10 are referred to.

Abstract: 25,083. Rawlins, F. Nov. 3. Mud-guards for motor and other road vehicles are constructed so that they may be readily dismounted or put into place. The mud-guard shown in section at b is provided on its underside with lugs b<1> carrying a tube a, in which is mounted to slide a socket member e, spring-pressed inwards, and having an enlarged tapered head e' carrying balls f in suitable apertures spaced round the head. When the guard is put into place by passing the socket member e over its appropriate spigot c projecting from the vehicle body, the spring pressure of the socket member e causes the balls f to cooperate with the coned internal surface d of the tube a to produce a frictional grip between it and the spigot c. In order to facilitate removal of the mud-guard, the socket member e may ba pulled outward by means of trigger i<1> and turned slightly to cause a lug a' thereon to engage the flush end of the tube a and retain the socket member in its inoperative position. Modifications are described (1) in which the wedging action of the balls causes a split end of the socket member to frictionally engage the spigot and (2) in which the balls are held in apertures spaced round the spigot member, which is hollow, and are pressed outwards by a coned wedge member within the spigot.
