Title: Improved Furnace Grate with Automatic Feeding Contrivance.
Inventor: FROUVE ALBERT
Filed: 1898-12-24
Granted: 1899-03-25
Abstract: 27,247. FrouvÚ, A. Dec. 24. Mechanical stoking; firebars and grates; smoke-consuming.-The intermittently-rotating conveyer C regulates the supply of fuel fed from the hopper to the inclined table B, and thence to the grate. The compound firebars E, which are constructed as shown in cross-section in Fig. 5, are furnished with saw-like teeth. By means of cams C<1> working in recesses in the firebars, the latter are given a reciprocating motion, adjacent bars moving together or otherwise as desired, so breaking up the bed of fuel and pushing the burning fuel and ashes towards the opening G. A supplementary supply of air is admitted through the opening G and regulated by means of the register G'. The cams C' are driven from the shaft M, which also drives the conveyer C by means of the ratchet and other gearing shown. Coned pulleys q, N allow the rate at which fuel is supplied to the grate to be regulated. The invention is shown as applied to the furnace of a water-tube boiler.

Inventor: BIRKBECK HENRY
Filed: 1899-09-05
Granted: 1899-11-04
Abstract: 17,911. Birkbeck, H., [Dieterich Gear Co.]. Sept. 5. Lathes; gearing, driving. -Relates to variablespeed gearing applicable for lathes and other machine tools. The driving- shaft o', Figs. 4 and 5, is connected to the driven shaft k<2> by an eccentric intermediate shaft b<2> and sets of toggle-levers m<1>, m<2>, the inner ends of which are loose upon the driving and driven shafts respectively, while their outer ends are pivoted upon discs R<3>, R<2> on the shaft b<2>. The toggles on the driving and driven sides are oppositely disposed, and their inner members carry nipping - pawls adapted to engage one after the other with discs d' upon the shafts o<2>, k<2>. The speed ratio is regulated by varying the eccentricity of the intermediate shaft. The toggle mechanism provides an automatic regulation of the position of this shaft with changes of load upon the driven shaft. In a simpler form of the mechanism, the toggle-levers are replaced by arms slotted to engage with pins on the discs. Figs. 8 and 9 show the embodiment of the invention in a cycle driving-mechanism. The toggles here consist of rings m mounted upon collars Q, Q<1>, and links n<1> pivoted upon a ring U which runs in ball bearings in a ring U<2> pivoted at U<3>. The collar Q is fixed upon a sleeve secured to the crank axle, and it drives each of its rings m in its turn by means of a ball clutch ; the collar Q', driven by each of its rings in turn by means of a ball clutch, is secured to the chain-wheel Q<2>. Fig. 10 shows the application of the invention in connection with a countershaft for lathes &c. The driving-pulley R<6> and the driven pulley R<7> are mounted loose upon a shaft o, and enclose a cylinder o' which is supported in a bearing b<3> and fitted with rings l<7> and m<7>; the rings l<7> are connected to pins near the periphery of the driving part by telescopic rods l<6>, and the rings m<7> to the driven part, by links m<6>. The position of the cylinder o<3> is controlled by a rod F' screwed at its upper end into a bracket G<7>; the screw and the nut in the bracket are, however, fluted so that the rod may be turned into such a position that it is free to move up and down, and so allow the cylinder o<3> to take up a position determined by the spring S and the load upon the pulley R<7>.

Granted: 1900-02-03
Abstract: 24,461. Arnhold, H. Dec. 8. Lighting and extinguishing gas. - A pneumatically-actuated valve is arranged in the gas-supply pipe, between the source of supply and the branches of the various burners. The special fitting comprises a tube A provided with a lateral valve chamber B and a partition N. In the construction shown in Fig. 1, the chamber B is divided into two compartments C, D. When the air in the chamber C is exhausted by means of an air pump, the depression a in the upper end H of the double piston valve fits upon, and is retained by, the leather or rubbercovered projection b in its raised position, in which gas can freely traverse the channels E, F. But, when air is forced into the chamber C, the valve falls into the position shown, and its end J closes the gas passage E. By lengthening the connecting-spindle L, the valve may be opened by forcing air into the chamber C, and vice versÔ, or the double piston valve may be replaced by a tumbler-shaped valve, which works in a single chamber, and is of sufficient length to close both the passages E, F when in its lowest position. In another modification, the channels E, F are closed or opened by a flexible bottle-shaped or other bag, into which air is forced, or from which it is exhausted. Gas to supply the pilot jets of the burners passes through a hole G in the partition N, and is controlled by a screw R.
