Which of the following most accurately describes the problem?

SPEED GEAR. — Humphris. — No. 17,217, dated 31st July, 1906.—The live axle (3) receives its motion from the driving shaft (5) through a perforated plate (1). The plate is connected by a claw dutch (16) to the outside member of the differential gear. The driving shaft (5 carries a telescopic member (7) whereon is mounted a pinion (4). To change the speed, the plate is moved back out from engagement with the pinion (4) by means of eccentrics (18), the claws of the clutch (16) being long enough to permit this movement without disengagement. The pinion (4) is then moved endwise to bring it into engagement with a different portion of the plate. For reversing, the pinion is carried back beyond the outermost ring of holes in the plate, and is brought into engagement with a pinion (44). At the same time, the operating rod (38), whereby the wheel (4) is moved, rocks a member (33), and thus brings a wheel (24) into engagement with the driving plate (1). This wheel slides on a feather on the shaft carrying the pinion (44), and in this way the reverse connection is completed.

EMERGENCY BRAKE. — Cornelius and Another.—No. 18,689, dated 21st August, 1906.-1n order that an emergency brake for operating on the road surface may be applied from various points of a vehicle, it is connected to an arm (C) on a rock-shaft (B). Free upon this rock-shaft is a toothed quadrant having a lug (M). The quadrant engages a screw spindle (H) whereby the brake may be applied, and, as the quadrant is rotated, the lug (M) comes into contact with a projection (N) fast on the shaft (B) which causes the shaft to turn for the purpose of applying the brake. Free movement is allowed between the lug (M) and projection (N) in order that the brake may be applied, when desired, by a hand lever (E) and link (F). The link (F) is connected to an arm (X) on the rock-shaft (11), and is adapted to turn the rock-shaft through the same angle as would be effected by the quadrant when operating the brake.

VEHICLE FRAMES.—Daimler Motoren Gesellschaft —No. 25,103/06, dated (under Convention) 9th November, 1905. —According to this invention, the part (n) of the axle upon which the spring (w) rests, is formed as shown in section at opposite points, and having a flange at eacti. side. The spring buckle (w) has a segmental ring (g), the gap of which is of such a size as to allow of inserting the part (n) into it. For mounting the spring buckle (w) the ring (4-) is placed upon the axle in the position shown in the smaller figure in which the gap coincides with the narrow side of the part (n), and afterwards is turned 90 degrees into the position shown in the larger figure. In this manner the ring (g) is held securely upon the axle, but is capable of oscillating thereon together with the spring buckle (w) and the spring (m).

SPRING WHEEL. — Mekarski. — No. 2,860/07, dated (under Convention) 6th February, 1906.—The spokes of this wheel are formed of a series of V-shaped, laminated springs, the ends of which are fixed between blocks (el, e2) and heads (11, z2), The spokes are preferably arranged in pairs, and the elements are disposed on opposite sides of a central plane.

FUEL VAPORISER. — Cottrell. — No. 23,215, dated 19th October, 1906.— An adjustable beater comprising a tubular portion (a) is arranged to serve as a conduit between the carburetter and the combustion chamber of the engine. Tubes pi of a zigzag form are connected to the tubular portion, or conduit (a), and these are adapted to serve as a bye pass through which a mixture of oi vapour and air from the carburetter ma be caused to pass, instead of passim directly through the conduit (a). B means of a valve (c) arranged in a cylin drical chamber in the conduit (a), th quantity of the mixture directed throng' the bye-pass can be regulated as desired Both the direct conduit, and the bye-pas connection, are enclosed within a box (i through which exhaust gases are cause to pass on their way to the atmosphere.

AUXILIARY RIMS FOR WHEELS.Davies and Another.—No. 26,186, date 19th November, 1906.—To prevent a auxiliary rim attached to the wheel of car creeping, a lug (1) carrying O.; brackets (2, 2) on which a leather strap (. is placed, is attached to the auxiliai wheel (a). Two sliding rings (4) are a ranged on the strap which is placed rour

one of the spokes (5) of the vehicle whee This strap can be removed from the arr (2) or tightened thereon, by sliding t1 rings (4).

TRANSMITTING MOTION.—Cordni —No. 16,925, dated 27th July, 1906.—Ti rods (ii, 12) are disposed within a tube ( and these move in straight parts of t tube, and are connected by a flexible wi (c) on which balls (d) are threaded so to be in contact with each other. It w be seen that, if either of the rods (In , are moved longitudinally, a correspondi motion will be imparted to the other rc

a pull being taken by the wire, and a pu being transmitted from ball to ball, they are in contact with each other.
