Title: Improvements in Incandescent Oil Lamps.
Inventor: MOREL LEOPOLD RALPH ATHENOR
Filed: 1897-09-15
Granted: 1898-08-13
Abstract: 21,202. Morel, L. R. A. July 28, [date claimed under Sec. 103 of Patents &c. Act, A.D. 1883]. Incandescent oil lamps. -In order to obtain a stable blue flame without smoke, the central air supply, which is sufficiently heated and moves sufficiently slowly to permit the formation of a flame on the inner side of the wick, is deflected by a collar b into or beneath a hollow or other spreader g, by which it is directed horizontally upon the main flame. The outer and cooler air current ascends between the burner cones d, e with sufficient velocity to prevent the formation of flame, except at some distance above the outer and upper surfaces of the wick. The number, the height, and the form of the burner cones used may be varied ; or a single burner cone may be employed, forked at its upper end to form a pocket of reserve air to equalize the air supply ; or a single burner cone may be provided at its upper end with an annular enlargement having perforations to direct a horizontal current of cool air upon the outer and upper surfaces of the wicks. The form and dimensions of the burners may be varied, and the accessory arrangements may be modified.

Abstract: 21,488. Weldon, L. Oct. 27. Yarns, mercerizing.-Consists in the combination with a dye-tub of means whereby skeins of yarn may be subjected to great tension for the purpose of mercerizing. The skeins, shown in dotted lines, are carried by an outer series of sticks, supported between a pair of large toothed wheels B, and an inner series of sticks, supported between a pair of smaller wheels C, loosely mounted on the same shaft, the inner pair of wheels being capable of rotary motion relatively to the outer pair. The outer wheels are driven by toothed gearing b, c, which derives its motion through worm gearing e,f from a pulley shaft g, provided with reversing-gear. Before introducing the mercerizing-liquid, the inner pair of wheels are rotated relatively to the outer pair, so as to stretch the skeins. This is effected by means of worms D, the shafts of which are journalled in bearings on the large wheels ; these worm shafts are driven by worms F on a cross-shaft also journalled in bearings on the large wheels, and actuated by a pinion G running on the periphery of a looselymounted spur-wheel H, which for the time being has its motion arrested by a brake actuated by a lever K.

Granted: 1901-05-04
Abstract: 10,766. Hamilton, J. H. June 13. Gas engines.-Two pairs B, D of coaxial cylinders drive cranks at 180‹ on a four-stroke cycle, and are flushed by air supplied by a double-acting pump F through pipes J, K. One end of the pump and the pair of cylinders it serves may be supplied by a common suction valve. The admission valves Q, Q<1> and the exhaust valves P, P' at the ends of the four cylinders are worked by four cams, the levers being arranged at intervals of 90‹ so that the cams on the shaft S may operate them at the proper intervals of time. Valves T, Figs. 3 and 4, control the air and gas supply. When the gas ports leading from the pipe R are closed during the scavenging period, the air ports from the pipe H are fully open, but, when the gas ports are open, the air ports are closed, except at one end, where there is a space sufficient to admit the air necessary to form a combustible charge. The valves T are operated by cam-actuated tappets, and controlled by a governor which moves the pivoted rods U out of the path of the tappets. The governor acts through linkwork or completes in succession the circuits to four electromagnets which attract the rods U. Each cylinder is provided with two igniters 0, 0', Fig. 6, either of which may be cut off by an oscillating valve W so as to admit of its removal for repair without stopping the engine. Air valves similar to those described in Specifications No. 6015, A.D. 1890, and No. 21,120, A.D. 1893, and the gas valve described in Specification No. 4189, A.D. 1892, may be employed. The cylinders are bolted between girders with lugs on them to receive the end thrust and with seats for the main bearings.
