Title: Improvements in Drawing Boards, Tables and the like.
Inventor: OPSAHL JOHAN BURCHARDT
Filed: 1903-09-02
Granted: 1904-07-14
Abstract: 18,912. Opsahl, J. B. Sept. 2. Tables.-A drawing table or board c is supported by pairs of legs a<1>, b<1> joined at their centres by a cross-bar. The board c is hinged to the legs a' and to bars d<1>, the lower ends of which are united by a cross-piece e which slides in slots in, or in slotted fittings attached to, the legs a<1>. A worm m turned by a handle m<x> gears with a wheel mounted on an axle h. Steel tapes are attached to the cross-piece e and pass round two pulleys on the axle h, so that, by turning the handle m<x>, the crosspiece e and bar d' can be raised or lowered, tilting the drawing-board into various positions. For adjusting the height of the board, the legs a<1>, b<1> may be loosely pivoted, or may have elevating- screws. The legs of the board may also be attached to a frame having a central pivot on which the board can rotate. Slotted tubes o, o are fixed to the sides of the board by screws, and semicircular sliding pieces p, which can move along these tubes, carry, by means of brackets q, a crosspiece n. Within the tubes are six pulleys, two at each rear corner, and one at each front corner, over which pulleys passes an endless wire. The sliding pieces p are fixed to the wires by clamps t, within the tube, to which the wire is attached by screws. On one side a sliding piece is attached to the lower part of the wire, and on the other side to the upper, so that, on moving forward the bar n, it will remain parallel to itself. A spring may be fitted to the wire to keep it tight. Slidably mounted on the bar n is a handle w<3> having arms w<1>, w<2> carrying a disk w to which is fixed a straight edge u<1>. A thin plate x to which are attached straight edges y, u<2> mounted at right-angles can revolve beneath the disk and can be clamped at the notches in the disk by means of a locking- piece y', or, in a modified form, the plate can be locked in any number of positions. The disk w is marked with degrees after the manner of a protractor. A dish w<4> attached to the handle w<3> serves to carry pencils or drawing-instruments.

Title: Improvements in Grinding Mills.
Inventor: ROBINSON AARON JOSIAH
Filed: 1904-01-16
Granted: 1904-06-09
Abstract: 1206. Robinson, A. J. Jan. 16. Disc mills, of the kind described in Specification No. 514, A.D. 1904. The material such as grain is fed from a hopper by a rotary feeder into a shoot 14, and so between the grinding-discs 11 through an opening or openings 16 in one of the discs. A hinged board 18 in the shoot 14 is actuated by a sliding-bar 20, which is fixed in any position in its bearing 22 by a screw. This board directs some of the unground material through an opening 17 in the casing 2 to pass directly with the ground product to the sifting-apparatus, this unground material preventing the fine product from clogging the sieve meshes. The unground material is eventually returned from the sifting-apparatus to be ground, passing into the lower part 15 of the feed shoot through ports provided with covers. A hood 23 inside the casing 2 over the opening 17 directs part of the air-blast produced by the rotating- discs through this opening 17, and down the feed shoot 15 again into the mill, so reducing the air blast passing into the usual elevators with the ground product, and tending to disperse this meal through the elevator crevices. This hood 23 also prevents the ground product from being dispersed by the air blast through the opening 17.

Title: Improvements in Registering Apparatus for Meters for Gas, Electricity, Water or other Fluids.
Inventor: HENDERSON JOSHUA HINDMARSH
Filed: 1904-05-11
Granted: 1905-04-06
Abstract: 10,836. Henderson, J. H., and Higgin, C. N. May 11. Counting-apparatus for fluid meters. The indicating-dials are caused to jump instantaneously from one numeral to the next, and to remain stationary between the jumps. A train of wheels is connected by a wheel or pinion a, Fig. 1, with the part of the meter operated by the flow of the fluid. The indicating-dials B are mounted independently of each other upon fixed studs G, and are provided with ratchet-wheels and pawls to prevent rotation in one direction. Each dial is provided with or attached to a disc b<1>, Fig. 3, carrying teeth b. A spring pawl F, which engages with the teeth, is carried by a spring lever E. The lever is provided with a projection d which bears against an eccentric cam D carried by an arbor of one of the train wheels. The lever E is thus moved back against the tension of a spring e by the cam, and springs forwards when released, causing the dial B to be carried round to expose the next numeral. A stop pin e' prevents the lever from moving too far. Each cam may have two, three, or four leaves, so that it makes onehalf, one-third, or one-fourth of a revolution for each jumping movement of the dial B. The dials are enclosed by a cover with apertures through which the significant numerals may be read. Where the dials count down to hundreds only, two additional apertures may be provided in the cover, through which two ciphers appear, so that the meter may be read correctly by non-technical persons. The numerals may be arranged on the edges instead of the faces of the dials, or the dials and train may be arranged to indicate in duodecimals or other systems.

Patent GB-190424874-A (GB)
Title: Improvements in and relating to Alternating-current Electric Generators
Filed: 1904-11-16
Granted: 1905-10-26
Abstract: 24,874. British Thomson-Houston Co., [General electric Co.]. Nov. 16. Dynamos, regulating; field magnets; sparking, preventing.-Relates to self-exciting alternators in which a portion of the armature current is rectified and supplied to the field windings, the object being to prevent sparking. Series and potential transformers are employed, and a non- inductive resistance is arranged in connection with them to render the field circuit practically non-inductive. Additional p o l e - pieces may also be fitted on the field magnets to reduce the reluctance to cross-magnetization due to the armature current. The commutator and brushes are so arranged that the change from one phase to another is made when the voltages are practically equal, and the field winding is never open-circuited. Fig. 7 shows one arrangement, in which A is an armature with a two-phase winding, F the field magnets, and C the commutator having two conducting-segments per pair of poles and two pairs of brushes. To one pair b<1>, b<1> is connected the circuit including the secondaries of the potential transformer P' and the series transformer T'. To the other pair b<2>, b<3> is connected the circuit including the transformers P<2>, T<1>. Non-inductive resistances R<2>, R' are connected across these circuits. Additional pole-pieces n, s may be fitted to reduce the reluctance to the cross-flux and to produce an effect as though the poles were actually shifted. This compensates for the shifting of the phase relations between the series and potential transformers due to varying load factor. Instead of using auxiliary poles, any other arrangement giving a low-reluctance path for the cross-magnetizing flux may ba used. Fig. 5 shows an arrangement adapted for a three-phase machine and provided with means for varying the impressed electromotive forces and the inductive resistances. Instead of using potential transformers, any other source of constant potential may be employed, such as a winding on the machine.

Title: Improvements relating to Cameras for Three Colour Photography.
Inventor: BUTLER EDWIN TRANTER
Filed: 1905-03-01
Granted: 1905-07-13
Abstract: 4290. Butler, E. T. March 1. Three-colour apparatus; three-colour systems.- In the camera for three-colour work, described in Specification No. 29,353, A.D. 1897, [Abridgment Class Photography], the positions of the "red" sensitive and "green" sensitive plates are interchanged. The first "pink" reflector a transmits red, orange, yellow, and blue, and reflects green rays. The second "yellow" reflector b transmits red, orange, and yellow rays on to the plate e, and reflects the blue and violet rays. By this arrangement the least active red, orange, and yellow rays are transmitted through both reflectors, the most active blue rays are transmitted once and reflected once, while the green rays of intermediate activity are reflected once. Green and blue colour screens f, g of suitable density are also provided to compensate further for the actinic value of the component colours. Instead of being parallel, the reflectors a, b may be at right-angles to each other, in which case the plates c, d will be at opposite sides of the camera.

Patent GB-190605237-A (GB)
Title: Improvements in or relating to Automatic Fire Extinguishers and Alarms.
Inventor: GOLDSMITH ABRAHAM
Filed: 1906-03-03
Granted: 1906-06-07
Abstract: 5237. Goldsmith, A., Francombe, G., and Scull, A. S. March 3. Sprinklers, automatic; alarms, fire.-A sprinkler valve is operated by the expansion of a capsule A containing ether or the like, and is automatically closed when the fire is extinguished. Preferably, a main and a supplementary valve are employed, the supplementary or smaller valve being opened first to allow some of the liquid to pass and thus to equalize the pressure on the main valve, the opening of which is thereby facilitated. The capsule A, Fig. 1, is placed at the bottom of the casing provided with an inlet E and an outlet E<6>, which communicates with one or more sprinkler heads. The expansion of the capsule A acts, through a projection A', flexible diaphragm G, and stem D, upon a supplementary spring-pressed valve C, arranged in a central opening in the main valve B, which slides in a chamber E'. Water then passes down apertures E<8> and between the walls of the chamber E<7> and valve B and thus past the valve C into the lower part of the casing. With a further expansion of the capsule, a collar D<1> on the valve stem D comes into contact with a shoulder B<3> of the main valve B, and thus raises the valve. In the modification shown in Fig. 4, the casing itself forms the sprinkler head, and is provided with perforations E<9> for the passage of water, while the valve stem D is attached to the diaphragm G. An alarm is sounded by the movement of the valve stem, a collar D<2> coming into contact with a spring J<3> to close an electric circuit through terminals J, J<1>.

Title: Improvements in and relating to Alternating Current Dynamo Electric Machines.
Filed: 1906-03-14
Granted: 1907-01-17
Abstract: 6195. British Thomson-Houston Co., [General Electric Co.]. March 14. Armatures; field magnets; sparking, preventing. -In self - exciting alternating-current machines having a commutator which rectifies superposed shunt and series currents from the armature for field excitation, as described in Specification No. 24,874, A.D. 1904, the auxiliary armature winding described in Specification No. 16,518, A.D. 1905, for the field current has its reactance reduced by the application of a short-circuited winding to the field magnet in inductive relation to the auxiliary winding. The short-circuited winding is particularly applicable to machines with laminated or with cylindrical field magnets. Within slots in the armature are wound the main armature coils A and the auxiliary coil a, which are held in position by suitable wedges. Upon the field magnet F<1>, shown as of the cylindrical type, are wound the field coils F, carried in slots in the field magnet. The field magnet is also provided with a shortcircuited distributed winding f in inductive relation to the auxiliary winding so as to act as a lowresistance short-circuited secondary to reduce the reactance of the auxiliary winding. This shortcircuited winding may be formed as shown by short-circuiting a few of the turns of the field coil and winding some of these short-circuited turns around the portions of the field magnet between the poles.

Title: Apparatus for Dispensing Liquids and the like.
Inventor: CORY JOHN CAMPBELL
Filed: 1906-05-10
Granted: 1907-03-28
Abstract: 10,980. Cory, J. C. May 10. Bottle holders; emptying bottles.-Relates to apparatus for dispensing beverages or other liquids, and consists of a holder for the vessels containing the liquids, which, while permitting the contents of the vessel to be drawn off, renders it impossible to refill the vessel or to withdraw it from the holder without destroying it. The holder is provided with a door, through which the bottle is introduced, and to the inner face of the door are pivoted links 78, formed with slots 79 and pins 81. The slots 79 engage pins 80 formed on the side arms 58, 59 of a hammer 62, which is adapted to break the bottle as hereinafter described. The pins 81 bear upon rocking arms 49, connected by cranks and rods 50<x> to a cross-head 51, adapted to clamp the bottle in position. In operation, as the door is swung open, the hammer arms 58, 59 are drawn forward against the tension of springs 60, 61, until a pin on the lower end of the arm 58 engages a notch in the underside of a catch lever 72. By this means, the hammer is set and locked until tripped. A bottle is now placed mouth downwards upon the top of a casing 22, and, as the door is closed, the cross-head is drawn down by the arms 49. Catches on the door engage latches on a lever 65, mounted on a shaft 64, and the door is locked. A corkscrew 20, mounted on a revoluble rod 13, is next screwed into the cork by bevel-gearing 9, 11 and a crank-handle 10, the rod 13 carrying upwards a rack 17, which turns a pinion 32 on a shaft 33 through one complete revolution, and a wheel 38 loosely mounted on a cam shaft 36 through half a revolution. The wheel 38 drives the shaft 36 in one direction only, through ratchet-gearing. The cork is withdrawn by turning a crank-handle 34 on the shaft 33, the rack 17 being returned to its original position. When the liquid has all been withdrawn, the crank-handle 34 is returned to replace the cork in the bottle, the wheel 38 completing its revolution and bringing cams on the shaft 36 into position to trip the catches holding both the hammer and the door. The hammer, thrown back by its springs 60, 61, fractures the bottle, and the door being opened, the cross-head is returned to its initial position, and the bottle is removed. A diagonal diaphragm 53, and side walls 54, 55, prevent broken glass from falling into the mechanism, the slots 56 for the hammer arms being covered by aprons for the same purpose. The liquid is drawn off by a tap 26 through a passage 24 and a cooling- chamber 25. A non-return valve 28 prevents back flow of liquid, and a pipe 31 acts both as a vent and as an overflow if an attempt is made to re-fill the bottle. Ice 29 is introduced into a chamber 30 through a door 83. The dome 6 of the apparatus is transparent.
