Title: Improvements in or relating to Speed Varying or Reduction Gear.
Inventor: FAIRFAX JOSEPH SINCLAIR
Filed: 1903-08-14
Granted: 1904-07-14
Abstract: 17,637. Fairfax, J. S. Aug. 14. Planing.-Relates to arrangaments for converting the high speed of an electromotor, engine, or line or other shaft into a slower motion either transmitted transversely by means of toothed, worm, belt, or chain gearing, or axially by means of a shaft coupled on to the slower-running sleeve, or into a reciprocating motion by means of a crank or eccentric. The reduced speed is stated to be applicable for machine tools, such as planing- machines, when the high speed may be used for obtaining a quick-return motion. The use of the high and low speeds side by side is stated to be an improvement on the invention described in Specification No. 12,321, A.D. 1902. Fig. 4 shows a section through the apparatus when combined with an electromotor. The main shaft a is provided, outside the bearing b, with a toothed wheel d. The internally-toothed ring e is rigidly attached to the motor case c and concentrically surrounds the wheel d. Planet wheels f gear with both the wheel d and the ring e, and are mounted on short shafts g carried by an armed frame or disc h having a sleeve i which is mounted to run freely on the projecting end of the shaft a. The sleeve i may carry a toothed driving-wheel, half a shaft coupling to which an axially-aligned shaft may be attached, or a disc for receiving a crank-pin or eccentric used for producing transverse reciprocating motion, or may receive a belt pulley k. The belt pulley is shown secured in position by means of continuations of the short shafts g carrying the planet wheels. When it is desired to use both high and low speeds, the shaft a is extended to receive a fixed pulley similar to k, so that a belt may be moved from the one to the other. The shaft a and the short shafts g are shown drilled longitudinally and transversely so as to provide channels for supplying lubricant to the bearing-surfaces.

Title: Improvements in or relating to Actinometers and Photographic Exposure Meters.
Inventor: DEGEN EDOUARD
Filed: 1903-12-21
Granted: 1904-02-25
Abstract: 27,986. Degen, E. May 12, [date applied for under Patents Act, A.D. 1901]. Actinometers.-In order to determine the correct time of exposure for photographing any desired object, two sliding coloured prisms g, h are used, one of which is adjusted to represent the diaphragm opening and the other to represent actinic illumination of the object. The prisms g, h are mounted on slides b, c with their outer faces parallel. The object is looked at through the openings m. The slide c is drawn out so as to cause the corresponding pointer i, Fig. 1, to coincide with the division of which the figure indicates the diaphragm-opening used. Then, while looking at the object through the opening m, the other slide b is first drawn out to the end of its travel and is then pushed back slowly and stopped at the point where the image of the object is almost obscured, whereupon the pointer, attached to this slide, will indicate on its scale the required time of exposure. Auxiliary scales are marked on the casing for very short and very long exposures. The scales are drawn on the principle that the logarithms of the times of exposure are proportional to the thickness of the coloured prisms.

Abstract: 11,249. Amidon, E. C. Jan. 28, [date applied for under Patents Act, A.D. 1901]. Hides and skins, raw and tanned or tawed, treating.-Consists of apparatus for bleaching or otherwise treating hides and skins, in which the hides &c. are immersed in succession in a series of vats by means of a carrier having a combined horizontal and vertical path of movement. An endless chain K, passing over sprocket-wheels D, E, F, H, the wheels E, F being capable of adjustment to prevent sag in the chain, carries frames N, Figs. 2 and 4. The frames are each provided with a series of cross-bars N<1>, over which the hides &c. are placed. These bars may be detached from the frame at one end by an arm 0, Fig. 2, disengaging the spring catch n<2>, which allows the shoulder n<4> to fall, as shown, so that the skins may be discharged automatically. A handle P, connected to a rod p, actuates a clutch on the shaft I by which, in the position shown, motion is given to the chain K, through spur gearing from a pulley I<2>. A row of vats A contain the different liquors in which the hides &c. are successively immersed. When a frame N enters the first vat, it depresses a lever R<1> which, by means of a spring r<1>, normally holds a rod R against one arm of a bell-crank lever Q', but, when the hides &c. are completely immersed, the rod R<1> flies back, and strikes the lever Q<1>. The lever operating through a rod q<1>, disengages the hook-catch Q when the handle P is pulled over by a spring p<1>, thus disengaging the clutch, and the apparatus is stopped automatically.

Title: Improvements in or relating to Dynamo Electric Machines.
Inventor: FOOT WILLIAM HORACE
Filed: 1904-09-05
Granted: 1905-02-16
Abstract: 19,126. Foot, W. H. Sept. 16, A.D. 1903, [date applied for under Patents Act, A.D. 1901]. Dynamos ; distortion of field, preventing collecting-rings ; commutators.-Consits of means for transforming a direct-current two-wire into a three-wire generator, which readily allow of the machine being restored to its original condition, and also in providing easily-accessible balancing- connections for the armature circuits of two or three-wire machines. The generator, Figs. 1 and 2, comprises the usual field-magnet frame 2, armature 3, commutater 4, brush-holders 5, brushes 6, and supporting-spider 7 and shaft 8. The usual end clamping-ring for the commutator is, however, replaced by a piece 12 carrying bosses 15, bolts 16 securing the whole to the spider 7, owing to a projection 13 and insulation 14 fitting into a groove 9 in the commutator 4. Bosses 18 on collecting-rings 17 of the type described in Specification No. 1238, A.D. 1902, are secured to the bosses 15 by means of bolts 20. Brushes 21, carried by arms 22, 23 from the ordinary brush-bracket 24, engage the rings 17, and are connected to auto-transformer or reactance coils 25, 26, Fig. 2, the middle points of the coils being joined to the neutral or balancing wire 27 of the distributing-circuit 28. The proper bars of the commutator, i.e., those which are normally at equal potential, are tapped and provided with pins 29 for connecting them, by way of conductors 30, coupling-sleeves 31, and terminal clips 32, with the respective rings 17. When solely used for balancing armature circuits, as in Specification No. 28,736, A.D. 1896, the brushes 21 and coils 25, 26 may be omitted entirely, or else disconnected from the rings 17. The number, form, and dimensions of the rings may be varied as desired, and, by replacing the above structure with the usual end ring, the machine is restored to its original condition.

Title: Improvements in Water Purifying Apparatus.
Inventor: SCHOU PAUL
Filed: 1904-10-10
Granted: 1904-11-10
Abstract: 21,777. Schou, P. Oct. 10. Mixing in definite proportions; moving-stirrer apparatus.-The working of apparatus for mixing definite proportions of chemicals with water is automatically regulated by the pressure of water supplied and the rate of its discharge into the mixing-apparatus. Water from the supply-pipe a is discharged into the funnel z by the curved pipes f, which radiate outwards from the bottom of the casing d. The casing is mounted on balls revolving in grooves on the pipe a, and is rotated in the direction indicated by the arrow g, by the discharge of the water. During each rotation, a cam x projecting from the casing comes into contact with a disc w, so as to push longitudinally a valverod r to which the disc is attached, and thus open for an instant the valve s and allow chemicals to fall from the receptacle q through the valve and through the outlet y to mix with the water in the funnel z. The spring t closes the valve as soon as the disc is released by the cam. The length of time during which the valve is opened is regulated by the pressure of the water, which raises a piston 2, Fig. 3, to which the cam is attached, against the force of a spring 3. The cam x is shaped as shown, so that when raised higher it will remain longer in contact with the disc. The casing d may support a shaft n connected to a stirrer p arranged in a receptacle q.

Title: Improvements in or relating to Free Wheel and Back Pedalling Brake Actuating Mechanism for Cycles.
Inventor: COURTIER ALBERT AUGUSTE
Filed: 1905-01-17
Granted: 1905-07-06
Abstract: 920. Courtier, A. A. June 15, 1904, [date applied for under Patents Act, 1901]. Clutches ; ratchet gearing.-In a free-wheel and back-pedalling brake-actuating mechanism for. cycles, in which a clutch is used for driving and a second clutch__for. applying the brake,. to prevent breakage of the parts in the event of defective engagement of the teeth, an elastic or other yielding device is provided. As shown in Figs. 3, 4, and 5, on commencing to drive, an internally and externally toothed ring 36, sliding along teeth 35, is moved by teeth 34 into engagement with teeth 33, so that, through the ring 26, the hub is turned. On stopping the sprocket-wheel, the teeth 33 drive back the ring into the teeth 34, and the hub runs free, while back-pedalling turns the disk 19 and applies the brake. Instead of using the ring 36, balls moving in cells, cut similarly to the teeth of the preceding arrangement, may be employed, in which case, to avoid breaking, a ring of width equal at least to the diameter of a ball, and provided with recesses forming continuations of those on the ring 26 and disk 19, may be freely mounted on the disk 19, so that, if the balls do not come opposite the cells, the loose ring is carried on to the required position. Fig. 1 shows another forward and backward driving-device, in which pawls 30, 31 are mounted on the sprocket-wheel and pressed inwardly by springs 32. For the forward motion, the pawls 31 drive the ring 26 and the hub ; when pedalling is stopped, these pawls slide over the teeth and the wheel runs free, while on backpedalling, the pawls 30 drive the disk 19 and apply the brake. The springs are arranged so that, when one set of pawls is in engagement, the other set is inoperative.

Granted: 1906-03-22
Abstract: 6572. Platt Bros. & Co., and Dodd, J. March 28. Lubricating s pin - ning - spindles. I n self-contained ring- spindles which are provided with a spout or funnel for lubricating purposes, the oil is made to reach a higher level in the bolster carrier than in the spout by means of a plug or cap which acts as a plunger. The invention is shown and described as applied to spindles constructed according to Specification No. 15,892, A.D. 1895. The plug i is a sliding fit in the spout h for part of its length, while the remainder has a slight taper corresponding to a taper at the end of the spout h so as to make an airtight and oiltight joint when plug is pressed home. The plug i forces the oil up the bolster carrier c to a higher level than that of the top of the spout h and it is maintained at that level by the tight joint made between the plug and the spout. When the level of the oil falls owing to the working of the spindle, it can be readjusted by withdrawing and reinserting the plug i, a cushion of air being formed which forces the oil up the bolster carrier. A square hole k is provided in the plug to facilitate its insertion and removal by means of a key.
