Title: Improvements in Mechanical Stokers.
Inventor: MAIER FRITZ FRANZ
Filed: 1897-05-24
Granted: 1898-05-07
Abstract: 12,833. Maier, F. F., and Kanitz, S. May 24. Steam - generator furnaces ; grates; mechanical stoking &c. -Relates to furnaces of the kind in which the feeding forward of the fuel, the clearing of the firegrate, and the removal of the clinkers and ashes are effected by means of a movable sliding grate in conjunction with a fixed step-grate provided with arrangements for cooling. Fig. 1 represents a vertical longitudinal section, and Fig. 4 a cross-section of a furnace with the improvements. The fixed grate is made up of ribbed hollow bars a between which the sliding bars of the movable grate are projected for forwarding the fuel and clearing the grate. Large openings are secured for the passage of air from the ashpit. For cooling the fixed grate, water or other cooling-medium is conveyed by the pipe c to the rear end of one of the hollow side frames A, from which it circulates in a serpentine fashion through the hollow bars and side frames. The supporting-bars f of the movable grate are guided between bars on the side frames A and are carried and operated by toothed quadrants f <1>. In its lowest position, the movable grate is balanced by the weighted lever f<4>. The sides of the frames are adapted to fit into the corrugations of the furnace flue, the filling-in flanges being on a level with, or above the surface of, the side frames. The flanges may be perforated. The fuel is supplied to the furnace by a hopper g having an adjustable bottom plate g<1> and a balanced back plate g<3>. In a modification, the plate g' is arranged horizontally, and provided with suitable means for its adjustment. Ashes and clinkers are discharged into the ashpit through the sliding plate h operated from the front.

Title: A New or Improved Machine for Crimping or similarly Treating Pile Fabrics.
Inventor: TAYLOR WALKER
Filed: 1897-12-02
Granted: 1898-10-15
Abstract: 28,420. Taylor, W. Dec. 2. Plaited or folded effects, producing.-In crimping, creasing, or folding pile fabrics to produce certain effects, the fabric x is fed by a spiked roller m to be engaged by the spikes d<1> on endless chains d carried over rollers b, c. The chains are guided underneath by a series of guides f pivoted at f<1> and converging together towards the rear, being adjusted by screws j, each of which actuates a pair of the guides. The fabric, on being thus fed by the chains d along a well or space n underneath, is creased longitudinally by reason of the converging guides. From the rear of the space n the fabric is fed between pivoted plates o<1>, p<1> by a roller p<2> acting in conjunction with endless tapes o<3> and with a web of canvas u<1>, which with the fabric is wound on a perforated roller S. In its passage between the plates o<1>, p<1>, the fabric is creased transversely. The fabric, with its canvas covering, is steamed on the roller S, which is perforated for the purpose. Instead of the roller steaming-arrangement, a chest arrangement for steaming is described in the Provisional Specification.

Title: Improvements in Twin Brakes for Cycles.
Inventor: COOPER CHRISTOPHER GEORGE
Filed: 1897-12-09
Granted: 1898-12-09
Abstract: 29,121. Cooper, C. G. Dec 9. Brakes for bicycles &c. Relates to modifications of the invention described in Specification No. 26,923, A.D. 1896, and consists of arrangements of twin-rim brakes to ensure direct action through the connections and equal application of the shoes. The usual brake rod A is jointed to a double bellcrank lever B, Figs. 1 and 4, which is connected by a rod C and a forked piece D, Figs. 2 and 5, to a double bell-crank lever E pivoted to brackets F on the rear fork. The horizontal arms of the lever E are connected by a cross-bar to which is pivoted a horse-shoe shaped frame G, Figs. 2 and 3, connected to blocks I, Fig. 3, carrying brake shoes J arranged to act on the rim of the rear wheel. The blocks I are formed with stems which work in tubes i on the rear forks and are fitted with helical return springs. In a modification. each block I is formed with two stems which work in holes in brackets on the forks. When the space between the forks is insufficient for the arrangement shown, the shoes are carried on a U-shaped metal strip, which slides on the forks, being connected thereto by turned-over metal tongues. In this case, the double bell-crank lever E is replaced by a single lever pivoted on a bracket on the down tube of the frame, and the frame G is replaced by a rod. The rubber &c. shoes are clamped between plates having slots in opposite directions through which the fixing-screws pass to allow complete adjustment. In a further modification, the shoes are carried by two horse-shoe shaped pieces arranged respectively in front of and behind the rear fork and coupled together. For ladies' machines, the sliding parts are arranged on the rear stays, the shoes acting on the forward part of the wheel.
Patent GB-189800233-A (GB)
Title: Process for the Production of Acetic Acid.
Inventor: PLATER-SYBERG COUNT HENRI
Filed: 1898-01-04
Granted: 1898-12-17
Abstract: 233. Plater-Syberg, Count H. Jan. 4. Acetic acid ; acetates.-Acetic acid is extracted from alkaline acetates as follows:-A solution of the alkaline acetate is electrolysed in the cold in a cell provided with a positive electrode of iron and with a porous partition. The negative electrode is preferably copper. The solution around the positive electrode is acidified with acetic acid to start the decomposition. Ferrous acetate and alkali are thus produced around the respective electrodes. The alkali may be used in the production of more alkaline acetate. The ferrous acetate is converted into ferric acetate by agitation with air, and this product is heated with neutral potassium acetate until the iron is all precipitated as ferric hydrate. The resulting bi-acetate of potassium is then heated for converting it into free acetic acid and neutral potassium acetate.

Title: Improved Acetylene Gas Generator.
Inventor: ROSS JOHN HOWARD
Filed: 1898-02-22
Granted: 1898-12-23
Abstract: 4372. Ross, J. H. Feb. 22. Acetylene. - Relates to generators, in which crushed carbide is fed into water at a rate corresponding to that at which the gas is used, and consists essentially in feeding the carbide through a tube which, as the gas bell rises, is carried to a horizontal position, thereby preventing any carbide from falling out, while, as the gas bell falls, the lower or delivery end of the tube also falls, allowing carbide to drop into the water. By these arrangements valves are not required. In the form shown, the crushed carbide is contained in a a hollow doubly-conical vessel e, pivoted at their pointed ends on brackets d, and provided with a charging-plug e<1> and a discharging-tube e<3>. Connected to the lower end of the tube e<3> is a flexible tube f, ending in a conical outlet b<2> leading into the water tank a. Into an annular space containing water, around the tank, dips the bell b. As the gas is generated, the bell rises, and carries the tube e<3> to the horizontal position, thus stopping the fall of carbide. The taps h are only required during cleaning &c. operations. Several modifications are described. In one, two carbide holders are employed, which, instead of being pivoted upon a bracket, run backwards and forwards along horizontal rails as the bell rises and falls. In another form, fixed carbide holders are used, and only the flexible end of the delivery tube e<3> moves up and down with the bell. In this case, the water space is divided into two parts by a removable valved dish-shaped diaphragm. In another form, the holder is separate from the generator, and, in a final form, a bellows-shaped holder is used.

Abstract: 14,284. Thompson, W. P., [Hicks, T. H., White, T. S., and Friant, T.]. June 28. Electric governors. - Relates to electrical means for governing engines, particularly those that drive electric generators. When the engine is running normally, an electromagnet E<3> moves a lever H carrying its armature which pushes the jointed end G<2> of the valve spindle G<1> into the path of the lever G'. When the speed is excessive, a solenoid D<2>, connected in shunt with the main circuit from the dynamo B, breaks the exciting circuit of of the electromagnet E<3> at E, E<1>. Another coil D<4> or D<5>, in series with the main circuit of the dynamo, may be used in conjunction with the solenoid D<2>, and acts in a similar manner to the compounding coil of a constant - potential generator, with the object of preventing a drop in the electric pressure when a greater load is put on the engine than that for which its governor is adjusted.
