Which of the following most accurately describes the problem?

TWO-CYCLE ENGINE.—Roots.—No. 25;983, dated 13th December, 1905.-1n this engine a differential piston is employed, the part (B) whereof is used as a compression pump. The cycle of operations is as follows :—During the instroke of the piston, air is drawn through the valve (E) into the chamber (D}, and, at the same time, liquid-fuel is drawn through a nozzle (not shown), and sprayed on to a series of perforated plates (F1), situated beneath a valve (F). During the outstroke of the piston, the air in the chamber (D) is compressed and forced past the valve (E) into a continuous combustion chamber (0). To pass the valve (F), the air traverses the perforated plates (F1), which are saturated with the carburetting liquid, and, thus, the charge is formed. The charge is ignited in the chamber (C), but does not enter the working cylinder until the valve (II) is opened. This valve is opened when the crank is at about the dead centre, anti is closed before the end of the out stroke, so that part of the out stroke is performel by expansion. Just before the out stroke is completed, the exhaust valve (W) is opened, whereupon the gases of combus

tion are ejected by the in stroke of the piston. The exhaust valve closes before the piston reaches the end of its in stroke, whereby a portion of the gases of combustion is compressed. This in stroke has again charged the chamber (I)) with air, so that the cycle of operations can be repeated. A device (R) is employed for introducing a charge into the chamber (G.) for starting purposes.

IGNITION PLUG.—H. C. Longford. —No. 27,046, dated 28th December, 1905. —The object of this invention is to provide a plug wherein the insulating parts may not be so clamped together as to cause splitting of the same The plug comprises a metal base (1) threaded -to screw into the wall of the cylinder. This base is hollow, and receives a metal cap (2). On opposite sides of the cap are insulating blocks (3 and 5), and a wire .031 extends through these blocks, and carries, at one end, a nut (7), and, at the other end, a shoulder-piece, whereby the parts are clamped in place. A third insulating piece (4) is introduced between the parts

3 and 5, but this is not clamped by these two members, and, therefore, does not become fractured by restraint, whilst it effects its purpose of preventing leakage of the curreet. The cylinder end of the base (1) is thickened so that a small orifice is presented to the cylinder. A sparking wire (10) is introduced tangentially in the wall of the plug.

WATER J ACK ET.—Strickland and Co., Ltd., and another.—No. 5,563, dated 7th March, 1906.—To simplify the connections between the water jacket and the radiator, the inlet and outlet passages (F and 0), respectively, are situated close together, so that both may be provided in one fitting. A T-piece is fast to a cover (I), and receives at one end (F2) the inlet pipe, and at the other end (02) the outlet con(luit. The end (F2) of the T-piece communicates first with a downwardlydirected conduit (E), and then with a horizontally disposed passage (F1), which lies within the water jacket (C), and whereby the incoming liquid is directed

to the valve chambers (B BI). The exhaust or outlet end (G2) of the T-piece communicates with a downwardly-directed tithe (G), situated near the base of the horitontal passage (F1), so that the returning liquid escapes thereby without interfering with the incoming liquid.

CLUTCW—Winton and another.—No. 13;674, dated 14th January, 1906.—The friction plates (18) on the driving shaft (3) are kept in frictional engagement with the plates (17) Oil the driving shaft (5), by a series of springs (19). These springs are meunted between a ring j7), secured to bolts (6) which carry the plates (17),

and a sliding member (9) adapted to bear against the plates (17). A collar (12) slides on the shaft (3), and has, at its end, jaws (16), which engage with jaws on a part (15) rigidly secured to the driven shaft (5), and this sleeve, thus, positively connects the driving and driven shafts. To disconnect this positive clutch, the lever (25) is moved in the direction of the arrow, whereupon the sleeve (12) is moved back against the action of its spring k27). This spring, being lighter than the springs (19), does not displace the member (9) until the lover is moved still further, when the friction clutch is, thus, also thrown out. On the reverse movement, the friction clutch first comes into operation, and, then, the positive clutch.

VALVE GLAND. —Dewrince. —No. 7,e99, dated 30th March, 1906.—The gland q) is retained in place on a collar (el) having depending members (e). The collar surrounds a screw-threaded shank, formed on the upper part of the bridge piece, and through which the valve spin

dle (a) passes. The collar lies beneath the nut (t1) carried on the stem, and, by screwing home the nut, the collar is kept in place. In order that the gland may be readily accessible for .repacking, etc., the collar is made open at one side, so that, by slacking the nut, the collar can be removed and the gland lifted from its socket.
