Title: Improvements in and relating to Alternating Current Dynamo Electric Machines of the Commutator Type.
Filed: 1908-05-28
Granted: 1909-05-28
Abstract: 11,633. Allgemeine Elektricitõts-Ges. May 29, 1907, [date applied for under Section 91 of Patents &c. Act, 1907]. Motors, alternating-current; field magnets; sparking, preventing.-Single-phase commutator motors having short-circuited working brushes a, Fig. 1, and exciting-brushes e are adapted for running on direct-current circuits by arranging the stator conductors 1, 1<1>, 6, 6<1>, 7, 7<1>, 12, 12<1> lying near the working and exciting axes into coils or groups of coils ha, h'a, he, h<1>e. In alternating-current working, the coils in the remaining slots 2, 2<1> . . . 11, 11<1> forming the winding w and the auxiliary coils ha, h<1>a, he, h<1>e are connected in series as shown at AC in Fig. 2. In direct-current working, the brushes e are disconnected, current is supplied to the brushes a, and the connexions of the coils h<1>a, h<1>e are reversed, as shown at DC in Fig. 2, whereby a field is produced at right-angles to the brushes a having a neutral or weakened zone in the neighbourhood of coils short-circuited by the brushes e ; the brushes e therefore need not be lifted from the commutator. The stator winding w in direct-current working is used as a compensating winding. In alternating-current working, the coils ha, h<1>a may be employed as commutating-coils and excited, for example, in the manner described in Specification No. 1662, A.D. 1907. On transition to direct current, the coils h<1>a, h<1>e may be connected in parallel with the coils ha, he. The coils w, ha, he may be permanently connected to form a single winding, the stator bars or conductors being connected as follows :-2-1<1>, 3-2<1>,4-3<1> . . . 12-11<1>. Fig. 4 shows a modification in which conductors situated near the working axis are joined to conductors situated near the exciting axis to form coils h, h<1>, the connexions of the coils h<1> being reversed in directcurrent working. In a further modification, the coils h, h<1> are produced by connecting together conductors in the slots 1-6, 1<1>-6<1>, 7-12 and 7<1>-12<1> commutating-coils, which may be used both in direct-current and in alternating-current working, being placed in the slots 1-1' and 12-12'.

Inventor: JAMES ERNEST CECIL
Filed: 1908-12-31
Granted: 1909-04-08
Abstract: 28,479. James, E. C. Dec. 31. With protectors and shades, eye, face, and like.- An adjustable sun-shade for hats is composed of a covered framework of spring wire attached to the hat and adapted to be expanded or contracted. The wire frame is formed by twisting the wire into loops at c, d, carrying it round a semicircle e corresponding to the front of the hat, again looping at f, h, carrying it round a larger semicircle k, then through the loop c, and finally looping it.again at i. The silk or other material which covers the framework may project a suitable distance below the edge of the wire k in the form of a veil.

Abstract: 3798. Carr, G. W., and Bullers, Ltd. Feb. 16. Throwing and tumiug.-Relates to means for forming electric insulators from roughly-shaped clay or other blanks by simultaneously drilling a central recess e, f cutting an annular groove n, and shaping a part or the whole of the exterior surface. A shank a adapted to be secured to a rotating spindle is formed with a depending arm c and radial arms b. The depending arm c carries a boring-tool d for drilling the central hole e and enlarged hole f; and the radial arms b carry outer tools n for shaping the exterior surface, boring- tools k for cutting the annular groove m, and inner too's j for rounding-off the surface at the top of the hole f. The tools are adjustably secured to the arms by means of set-screws. The shank a may be formed with additional radiating arms v carrying adjustable sleeves u supporting guides s for steadying the clay, which is held frictionally in a hollow chuck. As an alternative arrangement, the chuck carrying the clay may be rotated and the tools held stationary. When shaped, the clay is removed from the chuck and placed on the spindle of a lathe having its ends formed with a tapping- thread to cut a thread on the surface of the hole e for securing the insulator. The end r of the insulator is then turned to the finished shape in the usual way.

Abstract: 10,672. Loomis, O. P. May 5. Check valves ; seats.-A pressure gauge for indicating the explosive pressures in the cylinders of gas-engines, fitted with a coiled-tube damping-device B, such as is described in Specification 13,850/08, [Class 106, Registering &c.], is provided with a non-return valve having a small leak so as further to damp the indications. The valve J covering the inlet I lifts on increase of pressure, allowing the gases to pass by way of the passages 4 to the gauge; it is made to fit loosely on its seat so as to allow a gradual back-flow on decrease of pressure. Or the leakage can be effected by fitting the valve seat with a series of pins P of steel or other material harder than the seat so that they gradually project from the surface as the seat wears.

Abstract: 9 8 6 5 . Walmsley & Co., C., and Walmsley, C. April 22. Rotary filters or strainers.-Two rotary-drum strainers a, b, applicable for treating wood pulp &c., are mounted on a rocker bearing c, so as to counterbalance one another about a shaft d. The rocking motion is obtained from a driving- shaft h by means of an eccentric or cam j acting on an extension g of the rocker c. The strainers are rotated by means of a belt, chain, or the like passing round a pulley m on the shaft h, pulleys n, p on the drums, and an intermediate pulley o preferably on the shaft d. The pulley m is actuated from the shaft h by means of reducing-gear, such as the epicyclic gear shown in Figs. 3 and 4. As shown, the shaft carries an eccentric q working in the boss of an externally-toothed wheel r, which is prevented from rotating by means of stops on a non-rotating disk t. The teeth of the wheel r engage with internal teeth s on the pulley m.

Title: Improvements in Kneading Machines.
Inventor: QUENTIN FANIUS
IPC: A21C1/14
Filed: 1910-05-23
Granted: 1910-10-13
Abstract: 12,500. Quentin, F. May 22, 1909, [Convention datel. Rotary stirrers.-The arms of a kneading- machine are attached to a rotary shaft by sleeves which may be keyed to the shaft or connected to it by means of springs. In the latter case, pins on the shaft engage apertures in the sleeves formed so that the arm may move independently of the shaft for a portion of a revolution. For the operation of dilution, the arms 5, perforated at 14 and formed with sleeves 8 on the shaft 2, are keyed to the shaft at 7. For aerating and stretching, the key 7 is removed and the arms are then connected to the shaft by the spring 11. The drive is then effected as shown in Fig. 4. A pin 10 engages the top side of an aperture 9 formed in the sleeve 8, and lifts the arm. On reaching the topmost position, the arm moves forward independently of the shaft owing to its weight and to the assistance of the spring 11. The independent movement is stopped by the opposite edge of the aperture 9 coming in contact with the pin 10, and the arm rests on the dough until the pin 10 takes up the drive again. For removing the dough, the frame 4 carrying the shaft 2, the arms 5, and the gearing 6, is arranged to turn round the axis 15 so as to expose the container 1.

Abstract: 16,905. Lamplough, F. July 15. Clutches, friction.-Relates to double-acting cone or other clutches, hydraulically - operated during relative movement between the driving and driven members. The driving-casing a is provided with coned surfaces b, a<3> adapted to be engaged by cones c, c<1>, which turn with a block h' on the end of the driven shaft h. A flexible diaphragm d bears between flanges on the cones, which are normally disengaged by springs e. Secured to the casing a is a sleeve g with an eccentric part g<1>. In the part g<1> bears a ring g<3> which carries a pin g<4> engaging a piston j in the block h<1>. During relative movement between the sleeve g and ring g<3>, oil passes from the casing a into an orifice o<1> in a sleeve o, which is kept in position on the sleeve g by a spring pin o<2>. During the suction stroke of the piston j the oil passes through slots g<5> on one side of the sleeve g, and during the pumping-stroke it is pumped through a passage j<1>, past a valve k, into the diaphragm d, and puts the cone surfaces into engagement. Leakage between the block h<1> and sleeve g is prevented by the use of a plunger h<3>; Fig. 4, surrounding the piston j and pressed by springs h<5>, and by the oil pressure during the pumping- stroke, against the sleeve g. The clutch is disengaged by the movement of a sleeve l, which bears on pins m operating a bar m<3>, which in its turn opens valves k, n, thus permitting oil to escape from the diaphragm d through passages h<2>, g<6>.
