Which of the following most accurately describes the problem?

No. z9,24x, dated September 6th, 1904. —Vehicle Wheel.—T. Jones, of the Jones Haulage Syndicate, Warwickshire.—The wheel is provided with an ordinary tread (A) adapted for running upon roads and a bevelled tread (13), so that the vehicle may be placed upon rails. Within a groove (C) is a resilient split ring (D), which may be expanded by any convenient means to engage a tramway track if desired.

No. 8,783, dated April 26th, '905.— Spark Arrester.—D. Stewart and Co., Ltd., and J. B. T. Crosbie, both of Glasgow.—The funnel (A) of a steam motor is covered in by a series of gauze sections (d) carried by arms (D) pivoted at C in a frame (B), and connected by arms (E) to links (I') and an operating rod (G). By raising or lowering the rod (G) the spark arrester is closed over the funnel, or thrown open as shown in the drawings.

No. 28,122, dated December 22nd, 1904. —Electric Ignition Device.—J. l'axman and Another.—A connecting rod (B) re

ciprocates a rod (D) connected by a bell crank lever (A) and rod (a) to the oscillating armature of a low-tension magneto device. The bell-crank lever (A) is moved in one direction only by the connecting

rod (B), and in the other by a spring (F). The rod (B) is reciprocated by a crank pin (E) on the half-time shaft (X) of the engine, and is provided with a slot (0), which engages a pin (H), so that the end (b) of the connecting rod takes the path indicated in dotted lines. As the rod advances it engages a trip (C) pivoted at c, and connected at al to the rod (D). The rod (D) is thus moved against the action of the spring (F) until the end (b) of the rod (B) drops below the trigger (C), when the rod (D) is allowed to return suddenly, and by rocking the armature produces the required electric current. The return of the rod also causes the lever (G) of the sparking device to be struck, so that the contact in the cylinder is broken at the required moment. The moment of ipition may be varied by making the pin (Hi eccentric, and adapting it to be adjusted by partially rotating it. This causes the end (b) of the connecting rod (B) to release the trip (C) earlier or later, according to the direction in which the pin is adjusted. No. 12,279, dated May 3oth, 1904.— Friction Clutch.—Baker, Blackheath, S.E.—The clutch comprises two series of concentric rings, e and f respectively, the rings e being connected to a member (b) on, say, the driving shaft (a), and the rings f to a member (a) on the driven shaft. Outside the rings arc four segmental blocks (k), and within the series of rings is a similar set of segmental blocks. The four outer blocks are connected together by right and left hand screws having operating arms (m), and the inner series are similarly connected by right and lefthand screws, also provided with operating arms. The two sets of operating arms are connected to a sliding sleeve 01), and when this sleeve is advanced to

wards the clutch the screws are all simultaneously rotated, so that the outer and inner segmental members advance towards each other, with the result that the concentric rings are made to grip each other, and the clutch is brought into operation. Obviously a reverse movement releases the clutch.

Thirty-three motorcars left New York 011 July lith for Hartford, 122 miles distant, this being the first stage of a long tour organised by Mr. Charles J. Glidden, who is driving his Napier. It is of interest to note that a Packard and a ,Knox truck carry the participants' baggage.
