Patent GB-190411604-A (GB)
Title: Improvements in Dynamo-Electric Machines
Inventor: WILSON LEONARD
Filed: 1904-05-20
Granted: 1905-03-02
Abstract: 11,604. Wilson, L. June 1, A.D. 1903, [date applied for under Patents Act, A.D. 1901]. Armatures; commutators; field magnets.-Relates to the construction of direct-current machines adapted for high speed, the object being to prevent the use of wide brushes without sparking. An auxiliary armature with adjustable field magnets is connected with the main armature, and produces an auxiliary electromotive force in the leads under the poles. Fig. 1 shows an arrangement, and Fig. 5 a diagram of the connections. The auxiliary field magnets F are carried on brackets, fixed on the main field magnets A and similar to brush-holders, and are thus adjustable. The auxiliary armature E may be a ring, and each lead to the commutator H from the main armature C has a few turns, Fig. 4, on the auxiliary armature of comparatively high resistance to prevent a considerable current when short-circuited by the brushes. The field coils f give an electromotive force to compensate for the voltage drop due to the resistance, and, by adjusting the position of the magnets, proper reversal of the current is secured. Fig. 4 shows a modified arrangement, the auxiliary field having two poles at each brush g, so that the electromotive force in the auxiliary coil is reversed before leaving the brush.

Title: Improvements in Apparatus for Cooking Garbage or Offal and Removing the Oil therefrom.
Inventor: WHEELWRIGHT CHARLES STOREY
Filed: 1904-06-27
Granted: 1904-07-28
Abstract: 14,483. Wheelwright, C. S., and Fiske, J. T. June 27. Refuse, treating.-Garbage or offal is treated with steam in the digester A to extract oil. The steam enters from the pipe P<2> through an injector at the top of the pipe P<6>, and passes down the pipe through a central heater D to the bottom of the digester. The heater D receives steam from the pipe P<2> through the connection P<3>, and is fitted with a waste-steam pipe P<4>. The steam from the pipe P<6> is partially condensed among the garbage, and oil and water are forced up through a strainer B, having hanging teats b, into a trap formed in a stand-pipe above the digester. The oil and water are withdrawn from the trap to a receiver T by the pipe P<7>, which is fitted with a clapper valve regulated by a weight on the arm W<3>. The water occupies the bottom of the receiver, and the oil rises through the partition h, Fig. 2, and is trapped in the stand-pipe h<1>, any oil rising with steam towards the ventilator H being arrested by baffles h<2>. A connection is provided to draw-off the oil from the trap. The water from the bottom of the receiver T rises in the flow-pipe P<11> to a casting N', which forms a trap with the shell N. A ring valve or gate N<2> can be moved up and down by means of the band-wheel N<4> to regulate the height to which water can rise in the flow-pipe and the height of oil in the chamber T<4>. When cooking is finished, the steam entering by the pipe P<6> is cut off, and water circulation to wash oil from the garbage is obtained by opening the valve of a return pipe P<8>, which connects the flow-pipe P" with the top of the pipe P<6>. Fresh water, if required, can be admitted to the pipe P<8> from the pipe P<14>.

Title: Process of Dyeing Leather.
Filed: 1904-08-20
Granted: 1905-06-15
Abstract: 18,096. Abel, C. D., [Akt.-Ges. fiir Anilin- Fabrikation]. Aug. 20. Dyeing.-Leather is dyed with the reduced condensation product of nitrochlorbenzene sulphonic acid (NO2: Cl : SO3H=1: 4: 3) with m-phenylenediamine, or m-toluylenediamine, or chloro-mphenylenediamine. Chrome-dressed skins are dyed greyish-blue to blue-black with a mixture of solutions of the condensation product (sodium salt of p-methyl-m-amido-p<1>-amido-diphenylamine-o<1>- sulphonic acid) and an oxidizing-agent, such as hydrogen peroxide, a chromate, or an iron salt. The skins are stirred with the liquid in a tumbler, the oxidizing-agent, mixed with ammonium sulphate, being added after the dye. The skins are hung on a trestle without rinsing, and afterwards fat-liquored and sleeked. They are finished by staining on the table by means of a brush with a solution of a suitable blue or violet dye-stuff, which is capable of dyeing cotton without a mordant. This produces a soft black box-calf, which is wellpenetrated, has a fine grain, and, when out, shows a bluer shade than that obtained with logwood. The final staining may be done in the tumbler, immediately after the first dyeing, by adding the blue or violet dye and rotating the tumbler for half an hour. The skins are then hung on a trestle, fat-liquored, sleeked, and dried, the resulting effect being the same as with the first process. If vegetable-tanned leather is to be dyed, the proportions of the ingredients must be varied, and the first operation produces a grey to greyish-black, which must be compensated for by choosing a suitablycoloured dye, capable of dyeing cotton without a mordant, for the final staining.

Patent GB-190429017-A (GB)
Title: Improved Apparatus for Cushioning the Movements of Relatively Movable Members.
Inventor: MCCORD ALVIN CARR
Filed: 1904-12-30
Granted: 1905-01-19
Abstract: 29,017. McCord, A. C. Feb. 23, [date applied for under Patents Act, A.D. 1901]. Draw-gear; buffers.-The invention has special reference to draught rigging for railway cars but relates broadly to means for cushioning the movements of relatively - movable members. The movement of the draw-bar &c. is transmitted to the spring or other cushioning-device through differential or multiplying levers, so that the compression of the spring is greater than the motion of the bar. In the arrangement shown in Figs. 2 and 3, the inner end of the draw-bar 1 is provided with the ordinary yoke 2 enclosing and guiding the front and rear followers 10, between which the cushioning-spring 21 is confined. The rear follower does not bear directly on the spring but on a secondary follower 20<a> formed at the base of a cylinder 20 which slides in a casing 11 fixed to the front follower. The front of the cylinder 20 has projecting from each side a lug 24, which works in a slot in the side of the casing 11 and bears on a lever 17 which bears on a second lever 16 ; this lever, in turn, bears on an inclined abutment 19 on the rear follower. The pivots 18 of the levers are fixtures on the casing 11. When the draw-bar is pulled out from the normal position shown in Fig. 3, the front follower 10 being held fast by lugs on the framing of the vehicle, the rear follower moves with the draw-bar, and the levers 16 and 17 take the position shown in Fig. 7, So that the point of contact of the abutment 19 and lever 16 is shifted nearer to the fulcrum of the lever. The result is that the lug 24 is moved forwards through a greater distance than the rear follower 10 and pulls the secondary follower 20<a> away from the rear follower, the compression of the spring being thus greater than the motion of the rear follower. A similar effect results from an inward thrust of the draw - bar, the rear follower being, in that case, held fast by lugs on the framing of the vehicle while the front follower, and with it the casing 11 and the pivots of the levers 16, 17, is moved inwards with the draw-bar. The sliding contact between the levers and the abutments 19 and lugs 24 serves to damp the motion of the springs. Additional sets of the differential levers may be employed, and they may be otherwise arranged.

Title: Method of and Apparatus for Electrically Oxidising Atmospheric Nitrogen.
Inventor: HELBIG DEMETRIO
Filed: 1905-02-17
Granted: 1906-01-04
Abstract: 3346. Lake, H. H., [Helbig, D.]. Feb. 17. Electric furnaces.-In the oxidation of atmospheric nitrogen by the electric arc, the flame is confined or closely surrounded by an envelope of refractory material, such as calcium or magnesium oxide, which becomes incandescent and assists the passage of the arc. The electrodes may be of carbon or of metal. In the construction shown in Fig. 2, the points of the metal electrodes p, p<1> are kept from fusing by the liquid cooling device shown. The electrodes are fitted with packing h, h<1> into the block x of refractory material. The arc-chamber y, y<1> extends through the block at right-angles to the electrodes, and contains one or more pieces h' of the refractory substance, which further assist the arc. The gases follow the path a, b, r, z, y, y<1>, c in this way the gases undergo a preliminary heating before entering the arc-chamber. Plates i of asbestos or similar material serve as packing and prevent loss of heat, and a mica window s is provided. The arc is started in the ordinary way, and the electrodes are withdrawn as far as possible ; if desired, the points may be provided with a casing of the refractory substances. When carbon electrodes are used, they are withdrawn after starting the arc so that their points do not enter the passage y, y<1>, but rest within the electrode bores.

Safety devices for use with electric conductors.- Spark-gap devices for protecting electric conductors are arranged with the electrodes a, b at a greater distance apart so as to facilitate the entrance of the oil to extinguish any arc formed. This is done, as shown in Fig. 1, by placing a sheet c of some fusible or combustiblo material of better conductivity than oil between them. If desired, one or both of the electrodes may be covered with this material, or, as shown in Fig. 3, fusible electrodes a, b may be arranged parallel to one another with a sheet d of asbestos or the like between them, in addition to the sheet c. In this case, as shown in Fig. 5, the outer electrode b is connected to earth E by a comb or vane e.

Granted: 1906-01-11
Abstract: 15,061. Knudsen, K. July 30, 1904, [date applied for under Patents Act, 1901]. - Motor road vehicles.-Relates to vehicles having all four wheels mounted on swivelling axles for steering purposes, and consists of means whereby the front and rear pairs of wheels may be adjusted simultaneously in opposite directions for the purpose of running round curves, or may turn simultaneously in -the same direction, thus remaining parallel, so that the vehicle may move sideways without turning ; or the front wheels alone may be used for steering, the rear wheels remaining fixed. In the motor-truck, shown in the bottom plan view, Fig. 3, the swivelling axles of the wheels 5 are donnected by links to rockers 13, pivoted between the upper and lower axle members 2, 3 and turned by means of segments 18, 19 gearing with worms mounted on the universallyjointed shaft 22. The worms may be arranged to rotate simultaneously in the same direction for steering purposes, in order to deflect the two pairs of wheels in opposite directions, or they may be arranged to rotate in opposite directions so as to deflect the wheels in the same direction. The means for effecting these changes are shown adjacent to the front-wheels segment 19 in the bottom plan view, Fig. 3, and in an enlarged top plan view, Fig. 4. The front wheels are always connected to the steering hand-wheel, placed at the front of the vehicle, through the segment 19, worm 34, and shafts 24, 25. The rear wheels are connected through the shafts 22, 26 to the bevelwheel 44, which is clutched to the shaft 24 directly, or connected to it through the bevel-gearing shown, or left free, according as the clutch member 51 is moved into its right-hand, left-hand, or middle position. The clutch is locked in either of its three positions in such a way that the change of connexions can only be made when the wheels are set for straight running. With this object, one arm of the bell-crank lever 48 is provided with a pin 48<11>, which is adapted to engage either between, inside, or outside the concentric ribs 82, 83 formed on the segment 19, the change from one position to another being only possible when gaps in the ribs are opposite the pin. When the front wheels only are used for steering, the clutch-operating lever 47 locks the rear wheels against deflexion by engaging in one of a number of notches in a collar on the shaft 26. The controller for effecting the change of connexions detailed above is shown in Fig. 6, and consists of a handle 67, which is connected to the central operating spindle through a spiral spring in such a way that the handle may be set, but the corresponding connexion will not be made until the wheels are brought by the steering hand-wheel into the position for straight running.
