Title: Improvements in Indicating, Recording and Integrating Apparatus
Inventor: BOYLE JAMES MURRAY
Filed: 1903-03-27
Granted: 1903-05-28
Abstract: 7196. Boyle, J. M. Oct. 13, A.D. 1902, [date applied for under Patents Act, A.D. 1901]. Indicating and registering observations by instruments; pressure gauges.-A recording- pencil 34 is carried by a sliding rod 2, which also carries curved contact - pieces 4, 4<1>, and is moved longitudinally by a relay motor 6, so that the contact-pieces 4, 4<1> follow the transverse movements of the pointer 3 of a steam pressure gauge, a volt-meter, or other instrument, the action of the motor 6 being controlled electromagnetically by currents supplied through the pointer 3 and contact-pieces. The movements of the pencil 34 vary in any desired way relatively to those of the pointer 3, depending on the curvature of the contact-pieces. In the form shown, the contact-pieces are two insulated plates with curved edges, which may be faced with platinum wire ; the plates are secured on the rod 2 so as to leave a narrow intervening space, into which the pointer 3 projects, so that on deflection it touches either edge. Current then passes from a battery through this edge to one of two electric relays (not shown), and the relay so operated connects another battery to one of two pairs of electromagnets 9, 9<1>, 10, 10<1>. Each magnet acts on an adjustably spring-pressed iron lift valve 23, Fig. 5, faced with leather, in one of two casings 21, 21<1>, Fig. 1, connected to the ends of a hydraulic cylinder 6, the piston of which is attached to the rod 2. The left-hand valves 9,10 serve to admit pressure to either casing 21<1>, 21, while the right-hand valves 9<1>, 10<1> connect the other casing to an exhaust passage. The rod 2 may carry a pointer 33 over a scale 30. The pencil 34 marks on a drum 35 driven by a uniformly-rotating shaft 36. When the curvature of the contact-pieces 4, 4<1> is made such that the movements of the rod 2 are directly proportional to the quantity measured by the gauge &c., the rod may operate an integrating-mechanism, which may consist of a disc 39, rotated uniformly by the shaft 35, in frictional contact with a small disc geared to a square shaft 42. The gear is movable along the shaft 42 by an arm 46, either connected by rack and wheel gearing 72 to the rod 2, or carried directly by the rod 2. The square shaft 42 is turned by the small disc, and drives counting- mechanism 37. In a modification of the electric contact apparatus, the rod 2 carries a curved edgecam, against which a horizontally sliding rod is pressed by a weighted lever ; the horizontal rod carries two short straight vertical contact-pieces, between which the pointer 3 of the gauge &c. projects.

Title: Improvements in and connected with Apparatus for Raising Water and other Liquids from Wells and the like.
Inventor: JONET LOUIS
Filed: 1903-05-27
Granted: 1903-11-19
Abstract: 12,087. Jonet, L. May 27. Well-bucket type of apparatus.-Fig. 1 shows a sectional elevation of the arrangement. The pulley E is rotated by hand and so raises one of the two buckets, which, upon reaching the hook K, is grasped thereby and turned over, whilst the balance hook H is oscillated by the bucket holder N. The hooks Hare connected by a sleeve to the fingers c so as to operate the two pawls G, as shown in Fig. 3. These pawls are attached to the casing and prevent the full buckets from dropping if the handle is released. In a modification, the bucket empties through a valve in the bottom, this valve being actuated by a projection when the bucket reaches its upper position. In another modification, shown in Fig. 4, the base f is arrested at the edge of the delivering channel and the sides are raised further by compressing the spring h hand thus allowing the bucket to empty.

Title: Improvements in or relating to Apparatus for Use in the Manufacture of Acetylene Gas.
Inventor: ROSS ALEXANDER
Filed: 1903-06-13
Granted: 1904-04-28
Abstract: 13,301. Ross, A. June 13. Acetylene.-A number of carbide holders f, Fig. 1, normally held closed by a flap e, are arranged round the top of the water tank g. As the gas-bell b falls, a rod c strikes a projection d on the flap e, and discharges carbide. As the bell b rises owing to the generation of acetylene, and falls when the gas is drawn off by way of a pipe m, a projection h on the bell, working in suitable slots k, k<1> on the outer container a, causes partial rotation of the bell, so that containers f are successively discharged. The slots k' extend to the top of the vessel a, allowing the belt to be removed from the apparatus for recharging the holders f and cleaning the tank g. The guides k, k<1> may be formed of metal wires or strips soldered or otherwise attached to the casing a, or they may be pierced out of sheet metal, which is then used to line the casing a, or they may be embossed by suitable means on the walls of the casing a itself.

Title: Improvements in or relating to Fish-hooks.
Inventor: BOULT ALFRED JULIUS
Filed: 1903-10-02
Granted: 1903-11-12
Abstract: 21,172. Boult, A. J., [Krus, C. P.]. Oct. 2. Fdsh-hooks.-The points and barbs of fish-books are protected from weeds by means of a spring guard which is formed integrally with the hook. Figs. 1 and 3 show the elevation and plan of a hook with a guard c<2>. A slot c<1> formed in the end of this guard fits on the barb a<2>. Figs. 5 and 6 show a modification in which the end of the guard is formed into a ring with a slot in it. A bait book d is attached lying in a plane perpendicular to that of the fish-hook, and is of a similar construction. Fig. 8 shows another modification, the end of the guard being bent into a half-circle with a slot in it. Figs. 12 and 13 show a further modification in which the end of the slotted halfcircle is bent underneath the barb. Fig. 14 shows another modification. The guards are formed of such a strength as to protect the hook point and barb against weeds, but to bend inwards and serve as a lock when a fish bites. The guards, as at c', Fig. 6, and h<4>, Fig. 12, are made with the under surface bevelled so that if they happen to get above the hook point they are easily pressed back into their normal position.

Title: Improvements in or relating to Pneumatic Means to Regulate the Speed of Photographic Shutters
Filed: 1903-11-10
Granted: 1903-12-31
Abstract: 24,360. Tyler & England Bros., C., and Crabb, H. A. Nov. 10. Shutters.-A photographic shutter having pneu. matic means for regulating its speed has in combination with the air cylinder a, Fig. 2, the pipe c leading the compressed air from the said cylinder to the socket c<1>, Fig. 4, in a valve-casing d, a conical valve f, f being adapted to fit down upon a conical valve seating e. The position of the valve f, f<1> is regulated by the turn-button z on the front of the camera. The piston b of the cylinder a is connected to the shutter, which is operated by the bell-crank lever V and the spring V<1>. On screwing out the valve f, f<1>, the air from the cylinder a can escape readily from the socket c' by the air passages g, h, and hence the exposure is shorter than when the valve is screwed down. Thus the position of the valve determines the time of exposure, and the dial over which the button z turns is accordingly graduated.

Title: Improvements in and connected with Metallic Bedsteads and Cots.
Inventor: MOLINEAUX WILLIAM
Filed: 1903-11-20
Granted: 1904-10-13
Abstract: 25,340. Molineaux, W. Nov. 20. Castors; bedsteads and cots; cradles.-A detachable castor for metallic bedsteads has a pin 4 which fits in a central hole in a chill casting 2. The pin is provided with a spring wire loop 10 of inverted U-shape which passes over a groove 7, formed in the pin, the two ends of the wire being fixed in holes drilled at the lower ends of the groove. The wire loop is of such a size that it can be forced into the opening 4, but springs open when it reaches the top and prevents the withdrawal of the pin except by force. The casting 2 is retained in place by running in metal through one of the openings 13, 14 in the leg, the metal passing into a groove 12 formed in the casting 2. A depression 15 is also formed to receive the burr at the end of the pillar. If an ornamental casing is not used, an ornamental casting is formed round the base of the pillar. If the diameter of the pillar is too small to admit of the introduction of the casting 2 into its interior, the casting may be placed below it and secured by an external casting round the base of the pillar. In modifications, a spring ring, fitting round a horizontal groove at the top of the castor pin, or a spring 26 retained in place by a rod passing through it, Fig. 9, may be used to retain the castor in place. For cradles, detachable rocker bars are provided with upturned parts which fit into the castor sockets, after the castors have been removed.

Title: Improvements in, and Means for, Effecting the Regulation of Asynchronous Alternating, or Three Phase, Current Electric Motors and Rotary Converters.
Inventor: JOHNSON JAMES YATE
Filed: 1903-12-02
Granted: 1904-02-04
Abstract: 26,378. Johnson, J. Y., [Elektrizitõts-Akt.- Ges. vorm. W. Lahmeyer & Co.]. Dec. 2. Motors, controlling.-In the regulation of asynchronous alternating or three-phase current motors provided with flywheels or energy-storing masses which come into action when the load varies, the slip of the rotor is increased by means of a variable self-induction in the rotor circuit to render possible a larger variation of speed than usual. Motors of this kind are employed in driving winding-engines, rolling-mills. and other machines subject to variable loads. The variable self-induction consists of a choking-coil wound with a continuous-current coil, which is used to vary the degree of magnetic saturation and also. the permeability of the core, in addition to the coil in the rotor circuit. The deformation of the alternating.current and the inductive electromotive force in the continuous-current coil caused by this arrangement may be eliminated by dividing the choking-coil into two parts I, II, Fig. 1, each wound with an alternating-current coil w1, w2 and a continuous-current coil g1, g2, the coils w1, w2 being wound in opposition. In one regulating- arrangement, applied to a rotary converter having a flywheel, a centrifugal governor driven from the converter operates a resistance switch in the circuit g1 to vary the current supplied from a constant potential source. In some cases, the choking-coil may have two separate continuous-current windings acting in opposition and supplied respectively with a constant current and a variable and smaller current. In such cases, an increase in the variable current causes an increase in the self-induction of the coil. Fig. 4 shows a rotary converter or motor-generator D, G provided with a flywheel P and regulated in this manner by means of a choking-coil having coils w1, g1, g2, the coils g1, g2 being supplied with current from a constantpotential source and from the work circuit of the generator G respectively. Both windings g1, g, may be connected to constant sources, the current in the winding g1, g2 being varied by a resistance switch operated by an electromagnet in the work circuit. To prevent, in the arrangement shown in Fig. 4, the undesirable increased slip when the current consumption is large and the expenditure of energy is small, as when the motor A is starting, the coil g1 may be connected at such times across the armature of the motor A.

Title: Improvements in the Manufacture of Glue Gelatine
Inventor: SCHNEIDER OTTO
Filed: 1904-01-20
Granted: 1905-01-19
Abstract: 1477. Schneider, O. Jan. 20. Gelatine; glue.-In the manufacture of glue and gelatine from bones, hides, &c., the process is shortened by the use of oxygen, or salts yielding oxygen. After breaking the bones into small pieces, they are treated with solutions of salts yielding oxygen, preferably permanganates, barium and sodium salts, and peroxides and hydrates of the latter, or oxygen under pressure or not, and are also treated, previously or subsequently, with sulphurous, hydrochloric, phosphoric, or other acid, the quantity of acid necessary being reduced by nearly one half. The bones &c. are bleached, and a fine ossein obtained. After this maceration and the usual neutralization, the gelatine and glue are extracted with or without high pressure. The glue and gelatine liquors are clarified and bleached by adding phosphoric acid, calcium or other per- manganates, hydrogen peroxide, and sulphurous acid, in any order. The liquor may be heated before or after the admixture with or without subsequent filtration. For the manufacture of gelatine free or partly free from acid, the two acids mentioned, or one of them, may be omitted, and, for ordinary qualities, the hydrogen peroxide also. Suitable oxides or salts of barium and sodium, chiefly the peroxides and their hydrates, potassium and calcium hydrates and aluminium salts may be employed instead of permanganates.

Title: Improvements in the Arrangement and Construction of Carburetted Airs Gas Apparatus, relating to Automatically and Thermostatically Controlled Mixing Valves
Inventor: GLASSCOE THOMAS HENRY
Filed: 1905-01-10
Granted: 1906-01-10
Abstract: 435. Glasscoe, T. H. Jan. 10. Carburetting.-R e l a t e s to means for maintaining a constant proportion of air to hydrocarbon in a mixture delivered to the gas-holder, by automatically governing separate flows of air and more or less richly carburetted air by the use of temperature-regulated and other valves. Air from the blower i, Fig. 1, driven by the hot-air engine v, passes partly into the carburettor a by a branch pipe k, and partly through the branch pipe p, through a valve o behind the valve m, and into a mixing-box p. The carburettor consists of a number of absorbent baffle-plates in a chamber fed with liquid from the reservoir c through a vessel d containing a float-feed. Carburetted air leaves the vessel a by a pipe l, passes the valve m, and also enters the mixing-box p, from which the mixture passes through the valve q into the holder r. The bell is provided with a verticallyguided rod u, adjustably connected to one end of a slotted lever w, secured to the spindle of the valve q, the other end x carrying the adjustable end of a lever z passing through a hole in the spindle of the valve m. The movement of the bell thus controls the gas and mixture valves, the air valve o behind the valve m being similarly operated by a second system, To compensate for the effect of atmospheric temperature, the gas, air, or mixture can be governed by thermal devices actuated by changes in the temperature of the atmosphere or of a flame of the carburetted air. The auxiliary air or gas pipe is provided with a valve, consisting of a cock 2, Fig. 3, concentrically placed in the valve m and operated by a temperature-regulated device c' consisting of two chambers 3, 4, Fig. 5, separated by a partition 5 with a perforation 6. Both chambers contain mercury, which also fills the tube 13 projecting into the carburetting-chamber a. Variation of temperature in the latter produces a change in volume of the mercury and a proportionate alteration in level of the float 7, connected by the rod 8 to the spindle of the cock 2. The device is adjusted by means of a piston 11. In conjunction may he used another temperature-controlled regulator consisting of a drum 14, Fig. 1, containing air or other fluid, connected by a pipe 15 to a cylinder 16, in which is a spring-pressed piston 17 connected by a rod 18 to a bell-crank lever to a cock situated in the air-valve o. The temperature of the flame 20, which varies with the quality of gas supplied from the bell r, causes movement of the piston 17 according to the change in volume of the contained fluid, and actuates the valve to vary the volume of air passing to the mixing-box. The apparatus is supplied with an air-relief valve actuated by the rise and fall of the gas bell.
