Title: Apparatus for Incinerating Incandescence Mantles.
Inventor: CLAMOND CHARLES
Filed: 1899-01-31
Granted: 1900-01-13
Abstract: 2178. Clamond, C. Jan. 31. Incandescent gas &c. lamps.-Relates to apparatus by which mantles may be incinerated with only occasional attention from the person in charge. The attendant, after turning the three-way cock e to the position 1, pushes down the rack a, which carries a bunsen burner c, thereby winding up the driving-clockwork b, opening the valve f, and further opening the valve g of the pilot jet h. The enlarged flame of the jet h ignites the burner c, and the mantle m gradually burns downwards. As the clockwork raises the rack a and burner c and the attached mantle m, the valves f, g are returned to their original positions and the burner c is extinguished. The attendant then turns the cock e to the position 2, and again pushes down the rack a, thereby igniting a bunsen burner k within the mantle. Finally, the attendant turns the cock to the position 3, substitutes a burner l for the burner k by means of a slide n, and again pushes down the rack a. An annular flame from the burner l then plays upon the mantle from within simultaneously with the flame from the burner c without, the mantle, thus completing the incineration. The apparatus may be simplified by using a single burner in lieu of the burners k, l, and a pilot jet h which is independent of the apparatus.

Inventor: SCHLEGELMILCH REINHOLD
Filed: 1899-06-07
Granted: 1900-06-02
Abstract: 11,891. Schlegelmilch, R. June 7. Moulding picture frames &c.-Frames for pictures, looking-glasses, &c., of porcelain or other ceramic material, are made hollow and in one piece by pouring the paste or slip into a pair of double moulds forming a closed tube. The face b of the frame, Fig. 3, is made of any desired ornamental configuration, and the rear part or back is stepped as at a, c; the receding portion a serves to receive the mirror or picture. The moulds are of the form shown in Fig. 3, and are made of plaster of Paris, which is allowed to dry upon flat plates of the same substance so as to prevent warping. The hygroscopic nature of the mould causes it to absorb moisture rapidly, so that the porcelain slip poured into it, and adjacent to the surface of the mould, quickly sets. Slip is first deposited on the plain or back mould, and the mould is then filled with slip ; after the deposition of a sufficient thickness of porcelain, the superfluous slip is poured off by tilting the mould or the table upon which it is placed. Before the frame is thoroughly dry, openings for fixing the picture &c. and suspending ears are provided. The frame is allowed to dry on a flat surface, and is afterwards baked in a kiln and glazed upon the face.

Title: Improvements in Ignition Apparatus for Gas Burners.
Inventor: MARTINI ADOLF
Filed: 1899-07-21
Granted: 1899-09-02
Abstract: 15,077. Martini, A. July 21. Lighting gas.- Relates to apparatus for use in connection with catalytic igniters of the type described i n Specifications Nos. 22,901 and 27,198, A.D. 1898. In the apparatus shown in Figs. 1 and 2 for removing the catalytic igniter h from the path of the products of combustion after the ignition of the gas, the counterbalanced plate a carrying the igniter h is pivoted to a clip b, which may be so adjusted upon the upper end of the chimney, by means of the screws f and the holes e in the clip, that the force of the explosion upon ignition lifts the plate a with its igniter h into the position shown in dotted lines in Fig. 1. The counterbalance weight d and the ascending products of combustion retain the plate in this position until the flame is extinguished, when the plate falls back to the position shown in full lines. Instead of being mounted upon the pivoted plate a, the igniter h may be carried by a fixed support on the clip b, in proximity to a lateral hole in the pivoted plate ; or the pivoted plate may be dispensed with, the igniter h being then mounted on the end of a coiled spring, which expands when heated by the escaping products of combustion. In order that sufficient air may be mixed with the gas to ensure prompt ignition, the usual air supply is supplemented by air admitted through openings or scallops formed in the lower end of the chimney, or through a perforated ring by which a plain chimney may be attached to the usual gallery.

Title: Devices for Rendering Cranes applicable as Excavators, particularly for Batter Trimming and for Facilitating the Emptying of the Buckets of Excavators.
Inventor: BALDRY HENRY OSBORNE
Filed: 1900-04-19
Granted: 1901-04-19
Abstract: 7219. Baldry, H. O. April 19. Cranes.-Relates to means for rendering jib cranes applicable for excavating purposes, and to means tor operating the buckets of excavating-apparatus generally. The jib c of the crane, shown in partial elevation in Fig. 1, has iron stays 3 to which is pivoted one end b of a thrust-pole a provided with a rack d. The rack engages with a gear wheel e which is operated either by hand from the wheel m or by the crane mechanism from the mitre wheels j. The pressure of the rack upon the gear wheel e is relieved by rollers o, n supported in side frames q<1> hinged to the gear wheel shaft g. Undesired motion of the thrust pole is prevented, either by the band brake r or by a hinged weighted pawl, which engages the teeth of the rack. The frame q has a downwardly-cranked bracket 19, in which is supported the strengthened lower end of the jib c, and the jib is provided with parallel guides 15 on which run the rollers 8, 9, 10, 11 and 12 of the bucket carriage 7. The bucket 6 has one lower end pivoted to the bucket carriage 7, and one upper end secured to the hauling-rope 22. To allow clearance for the bucket when moving down a fresh cut, the end upper roller 9 has its axis placed slightly above the line joining the axes of the other upper rollers 8, and the axes of the lower rollers are correspondingly not in line. The downward motion of the bucket carriage is arrested, at the position for discharge, by a spring-pressed stop, so that further slackening of the hauling-rope 22 allows the bucket to discharge by turning about its hinged connection with the bucket carriage. The stop may be afterwards released by means of a rope under the control of the operator. The guides 15 are formed by securing to the jib c plates of I, T, Z or other section. In the modification shown in detail section plan in Fig. 6, the screw-threaded thrust pole u works through a nut v which rotates in a sleeve w provided with trunnions x bearing in the frame q. The nut v is rotated from the wheel f, hollow shaft 2, and bevel-wheels z. In a modification applicable to excavating-apparatus generally, the hauling-rope 22 connects the bucket to the drum 32 keyed to the shaft 33, and a second rope connects the bucket carriage to the loose drum 31. The engaging projections 34, 35 in the drums allow the keyed drum 32 to rotate almost one revolution after the loose drum 31 has been locked by a pawl engaging the ratchet-wheel 36.
