Title: Improvements in Variable Speed Gearing for Bicycles and the like.
Inventor: COPE ALFRED WILLIAM
Filed: 1904-09-15
Granted: 1905-08-03
Abstract: 19,914. Cope, A. W. Sept. 15. Driving - mechanism.-Rel ates to two-speed gears for bicycles and the like. The hub A, carried by ball bearings on the axle, has an enlarged part a' within which is the sleeve B bearing the toothed ring B'. The sleeve can slide along the hub against a spring, but is made to rotate with it by the feather b<2> engaging in the key-way a'. The ring C', carrying the chain-wheel c, has a toothed ring C and is mounted to revolve on ball bearings on the disc D, which is made in two parts and can move along the block E so as to have either a concentric or an eccentric position on the axle. The parts are kept together by the flanged lock-nut F. In one form, Fig. 1, the inner face of the ring C' has a ratchet-toothed crownwheel c' which, in the concentric position of the disc D, engages with the teeth b<1> on the sleeve and drives the hub. When forward pedalling is stopped, the momentum causes the teeth on the sleeve to be forced out of engagement with the inclined ratchet-teeth on the stationary ring C<1>. When the disc D, by hand-levers or other suitable arrangement, is moved to its eccentric position, the bevel b<3> causes the sleeve to be pushed clear of the teeth c', but the toothed rings B<1>, C engage and the hub is driven at a higher speed. In another form, Fig. 2, the ratchet-teeth b<1>, c<1> are not used, but, in the concentric position, the teeth C engage with teeth b<1> on the sleeve and, when pedalling stops, the sleeve is forced back by the lug b<3> in a helical groove a<3>. In a modification, low speed is obtained in the eccentric position, the toothed ring C meshing with the inside of a larger ring on the sleeve.

Inventor: SCHWARZ ALFRED
Filed: 1904-11-04
Granted: 1905-01-26
Abstract: 23,906. Schwarz, A. Nov. 4. Wet separating processes; metals, extracting.- - Metallic particles are separated from finely divided ores by means of fatty materials or hydrocarbons, such as oil, paraffin, tallow, ozokerite, palmitin, stearin, and the like, with which resinous and other materials, such as asphalt, resin, pitch, or the like, are mixed ; or, the separation may be effected by means of sulphur or sulphur compounds which may be mixed with fatty materials or hydrocarbons. The finely-divided ores may be moistened by means of steam and introduced into a receptacle a, heated, when desired, by steam, hot air, or hot liquid circulating through a jacket b. The fatty &c. materials are mixed with the ores and, if desired,. the mixing may be effected before the receptacle is heated, the sulphur and fatty and resinous substances being powdered, or in form of shavings or the like. According to another method, the dry pulverized ore together with a melted mixture of fatty substances &c., to which sulphur may be added, is charged into the receptacle a, or another receptacle. and loosened by means of steam or compressed air or other gas which may be passed into the receptacle, from annular pipes e, f provided with nozzles g preferably arranged tangentially to the periphery of the receptacle ; or the loosening of the mass may be effected by means of gas &c. evolved within the receptacle as a result of the action of hydrochloric acid or calcium carbonate, or as a result of decomposition caused by the addition of sulphur. The hydrochloric acid &c. may be introduced by the pipes e, f or additional pipes l, m or acidproof tubes i. The operation of loosening, thus carried out, converts the charge into a frothy mass, and into this mass fine jets of water are injected, the loosening operation being preferably continued. The metallic particles are carried by the fatty &c. substances to the upper part of the receptacle, and the gangue subsides, and is discharged through an aperture in the lower part of the receptacle. According to a third method, the dry ore is mixed with the fatty and resinous substances and boiled with hot water or steam, or is stirred up with hot water. When sulphur or sulphur compounds, alone or mixed with fatty &c. substances, are employed, acidulated or alkaline water may be used during the mixing the mass. A solution of caustic potash or soda may be used for washing the metallic particles, after they have been separated from the gangue.

Granted: 1906-03-30
Abstract: 28,992. Atkinson, L. V. Dec. 30. Furnaces for arsenic.-Relates to apparatus for the collection of arsenic evolved during the treatment of refractory ores. Along the roof of the furnace A, in which the ores are treated, runs a pipe B into which several openings B<1> lead from the furnace roof. The pipe is carried up to the roof of a condenser H, and at a short distance from the furnace is provided with an enlarged downtake C fitting over a sump D, under which is a firegrate E. The condenser is a chamber H, of brick, wood, or iron, provided with a steam and water spray a, a door L at the floor level, and a drain K. Above the floor, resting on frames I, are wire beds covered with loose blankets on which the arsenic is deposited. When the ore is stirred in the furnace, particles of fine ore will be carried up the pipe with the fumes. These particles being partially cooled will fall into the sump, but the heat from the firegrate E will vaporize any arsenic falling into the sump, the vapour passing into the condenser. The fine ore remains in the sump and is from time to time transferred back to the furnace.

Filed: 1905-03-02
Granted: 1905-08-24
Abstract: 4353. Niedenf³hr, H. H. March 2. Condensing nitric acid.-Nitric acid is prepared as usual by the distillation of a nitrate in a retort k, and the gases evolved are passed through a condenser b whereby the nitric acid is absorbed. The unabsorbed nitrous fumes are withdrawn by a fan, ventilator, or the like a, between which and the condenser is an inlet c for additional air for oxidizing the fumes. A small amount of air may be also introduced at the usual place, namely, at d. The mixed gases then pass to further condensing- plant or "tail apparatus" e, f, wherein further quantities of nitric acid are absorbed. This tailapparatus may consist of two absorbing or plate columns, such as e, in the first of which a concentrated solution of nitric acid is obtained by charging the column with a limited quantity of liquid, and in the second a dilute solution is obtained by charging the column with an excess of liquid so as to absorb all the gases possible. The dilute acid from the second column is used as the absorbent in the first column. A damper or the like h<1> can be placed after the list part of the tail-apparatus so as to regulate the pressure and the speed of the gases.

Patent GB-190513855-A (GB)
Title: Improvements in or connected with Screw Jacks
Inventor: LAKE WILLIAM BEARD
Filed: 1905-07-05
Granted: 1906-05-10
Abstract: 13,855. Lake, W. B., and Elliot, E. F. July 5. Lifting-jacks of the type in which a screw is operated by double-acting pawl-and-ratchet mechanism are provided with means for preventing the engagement of the idle pawl with the ratchetwheel, and also with means for roughly adjusting the screw to the height of the work. Figs. 4 and 5 show the lifting-jack, with the buttress threaded screw B, engaged by a coned nut F constructed in three or more sections. The nut F is in frictional contact with the inner coned surface of a hollow ratchet-wheel C having a ring of double teeth c at the upper portion of its periphery, and an annular groove c<2> in the lower portion which is engaged by a spring-pressed ball c<3>, secured in a recess in the casing A by the stud a<6>. A peg c<6> working in a slot on the nut F is used also to connect the nut and the cap c<4> of the ratchet-wheel. The ratchetwheel C also has a flange fitting on the shoulder a<1> of the standard, and is operated by a double pawl D, pivoted at d<2> to a pair of plates d<4> loosely mounted on the standard A. A spring guard-ring E, having its ends e bent outwardly, surrounds the ratchet-wheel, and by moving the handle d<8>, the pawl D, and the plates d<4> bodily round the standard, the central projection d<5> on the pawl can be made to engage one of the ends of the loose guardring and move it through a sufficient angle to allow either of the pawls to engage the ratchetwheel. The other pawl is prevented from engaging the wheel by the guard-ring. When pressure is applied to the screw in an upward direction, the inclined screw-surfaces force apart the sections of the split nut and allow the screw to be rapidly raised. To lower the screw rapidly, the jack is inverted, and the split nut then falls upon the coned cap c<4> of the ratchet-wheel, thereby forcing the sections apart and permitting the screw to be pushed into the casing. Other methods of connecting the nut and ratchet-wheel may be used ; for example, flat roughened surfaces may be provided on each, or the nut may be omitted and the inner surface of the ratchet-wheel provided with a screw-thread engaging the lifting-screw.

Patent GB-190605315-A (GB)
Title: Improvements in or relating to Military Equipments.
Inventor: WISE WILLIAM PIERREPONT
Filed: 1906-03-05
Granted: 1907-03-05
Abstract: 5315. Wise, W. P., and Twigg, W. W. March 5. Equipments and accoutrements; braces. -Relates to an arrangement of straps for carrying a greatcoat, an ammunition belt, a mess tin, and other accessories combined with buckles of the cross-bar type having gapped ends for enabling the straps to be adapted for carrying purposes without interfering with the general fit. In Fig. 1, the shoulder straps A are shown connected behind to a cross-bar, shown separately in Fig. 6, but may be connected individually to separate buckles, each consisting of a plain frame having four cross-bars similar to E<1>, Fig. 6. Fig. 7 shows a gapped buckle C for adjusting the front loops A' at the end of the shoulder straps as in Fig. 1. The straps, which are preferably of woven cotton, are pinched up so as to pass through the gaps, and thus avoid the necessity of one end being passed between two complete bars. The ammunition belt H, Fig. 4, is held in front by being passed through the loops A'. The end of each strap is passed a second time through a buckle C, and thus each loop A<1> may be extended without altering the effective length of its shoulder strap, though this may also be varied by sliding a strap through the buckle. The other end of the strap is passed several times, as in the left-hand side of Fig. 1, between the shoulder buckle D, Figs. 1 and 5. When a greatcoat is to be carried behind, the body of the strap is threaded once through the buckle as on the right-hand side of Fig. 1, and a bight A<3> on the end of the strap is passed under one gapped side of the buckle and encloses the members of the other gapped side. The surplus material previously taken up in refolding the strap is thus expanded into a loop, the size of which may be varied without interfering with the effective length of the strap, and a greatcoat L, Fig. 4, is carried in the loops. A vertical back strap B is, in the arrangement shown, slipped through the centre part of the back bar and folded between buckles B<1>, of the C type, and buckles G, of the D or shoulder-buckle type, so as either to form a plain loop through which the ammunition belt passes, or to pass round the mess tin &c. An additional strap K serves for the suspension of other articles. Instead of using a back bar, three separate buckles may be employed, one to receive each shoulder strap behind, and a central one for the back strap, connected by another strap with the other two buckles.

Title: Improvements in Systems of Control for Electric Motors.
Filed: 1906-04-10
Granted: 1907-03-21
Abstract: 8680. British Thomson-Houston Co., [General Electric Co.]. April 10. Motors, controlling.-Relates to control systems for motors which are reversed frequently under load, and which run at a higher speed in one direction than in the other, more particularly for planing and other machines having reciprocating parts. The motor M is compound-wound, the shunt field 3 is not opened during the reversal, and the series winding 2 is connected to the source of the current supply while running and during the time that the motor armature is disconnected preparatory to reversal. Adjustment of speed in the principal stroke is made by means of a rheostat 5 in circuit with the shunt field ; in order that the speed may be faster in one direction than the other, the influence of the shunt field is eliminated by means of a resistance 6 during one stroke. Fig. 2 shows a drum controller for a planing-machine actuated by stops on the table engaging with an arm on the controller. During the working stroke, the resistance 6 is short-circuited by contacts 7, 8, 17, 18, and the armature is connected in series with the field 2. When the stop comes against the arm at the end of the stroke, the following connexions are made as the drum is turned: (1) resistance 4 is thrown into circuit with series windings and armature, (2) the armature is cut out of circuit, (3) the armature is cut into circuit but reversed, (4) resistance 4 is cut out of circuit, and (5) resistance 6 is thrown in circuit with the shunt winding 3 and thereby partly eliminating the effect of the shunt windings and allowing the motor to make the return stroke as a series motor.

The chamber 13 above the piston communicates with the outlet pipe 6 through a small passage 15, but is filled with steam when a valve in a pipe 19 is opened by the rise of a float 20 or the contraction of a rod owing to accumulation of water, whereupon the piston 14 is forced down by the spring to open the discharge passage.
Patent GB-190615943-A (GB)
Title: Improvements in Brakes for Tramways and Railways
Inventor: PRINGLE PERCIVAL JOHN
Filed: 1906-07-14
Granted: 1907-10-14
Abstract: 15,943. Pringle, P. J. July 14. Brakes; rail-cleaners.-Emergency ekid brakes for railway and tramway vehicles are adapted to be wedged beneath the wheel flange in the rail groove so that the weight of the vehicle increases the braking force ; these brakes may be adapted to apply additional brakes to the wheels or rails, and special means for operating them and for clearing the rail groove are provided. The skid a, Figs. 1, 2, and 3, consists of a tapered bar shaped to fit the whole of the rail groove b. It is normally carried in front of the wheel, and can be advanced into the rail groove so that the wheel flange will run into a groove f in its upper surface. The wheel thus draws the skid backwardly, and the pull may be taken up by a spring, or utilized to apply another set of brakes which may be adapted also for manual operation. A shoulder h, or a flexible strip i, may be provided to clear the rail groove. The skid a, Fig. 6, slides through a bracket m on the truck frame, and is adjustably mounted on its supporting-lever by means of locknuts z, 1, so that wear can be compensated for. Screws o on the bracket bear on the wheel and relieve the bracket of strain when the brake is applied ; and a spring s, connected to a sliding loop t, is extended as the skid is drawn beneath the wheel. The brake may be applied by a spring v when a jointed rod w is moved over its dead-centre by means of a lever r. The skid bar may be carried by a loose connexion from the preceding wheel axle. The skid a may be combined with a shoe 7, Fig. 12, for acting on the wheel. In Fig. 11, the skid bar a is shown connected to an arm 4 mounted on the axle 6, so that, when the wheel c pulls on the bar a, the shoe 7 is forced on to the rail and the arm 4 exerts an upward pressure on the axle 6. The arm 4 may be mounted on an axle between the wheel axles, or on the axle of the wheel c. A skid may be carried behind the wheel to prevent backward motion on inclines. The skid may be corrugated, and may act on the tread as well as in the groove of the rail. Skids are arranged to act on the two wheels of one axle, and to be actuated together to equalize the retarding forces on the two sides of the vehicle. The skids may be applied automatically when the vehicle attains a certain speed.
