No. 24,841, dated November z6th, 1904—Friction Clutch.—Cleathero.—A driving shaft ifl) carries a disc (2), round which is fitted a shell (I), fast on the driven shaft. A split ring (6) is secured to the disc (2), and a second split ring (5) located within the first, is secured to the shell li). A third split ring (4) is secured to the disc (2), and a tongue (8) slides between its ends. The slide has pivoted to it two links (161, the free ends of which lie in recesses in the ends of the split ring. The slide (8) is operated by a lever (g) and links ('3), connected to a sliding sleeve (15) on the shaft (B), and when the slide is moved inwards the links (i6) are brought into an approximately straight line, so that the ring (4) is expanded and in turn expands the rings (5 and 6) ; the disc (2) thus drives the member (1), and the clutching of the two shafts is effected.
No. 26,753) dated December 8th, 1904.— Carburetter Air Control.---E. W. Lewis.— Between the fuel nozzle (A) and the mixing chamber a cock iC) is mounted, having a way (Cl) through it, equal in diameter to the passage through which the air for carburation is sucked. The cock serves as a throttle, and at the same time increases the velocity of the air past the nozzle when only a small quantity of air is being drawn through. The required proportion of fuel is thus always obtained by the rush of air past the nozzle.
No. 486, dated January loth, 1905.— Wheel Rims.—Beckwith Cave and Browne-Cave.—The frame (c) is carried upon a felloe by side plates (d) secured to the felloe by bolts (l). The rim is an easy fit upon the felloe, and by removing one of the plates (d) the rim, with, say, a deflated tyre therein, can be readily removed, and a spare rim with a tyre already inflated thereon can be slipped laterally into place. The rim may be further secured by radial bolts (f) if desired.
No. 13,675, dated July 3rd, tgo5.—Reducing (ear—T. B. Browne.—This reducing gear is inserted between the differential shaft (Z) and the road wheel sprocket. A bracket (A) is secured to the frame of the vehicle and provides a bearing for one end of the differential shaft (Z). On this shaft is a pinion (F) gearing with an internally toothed wheel (E) carried fast on a shaft (B), also mounted in the bracket (A). The shaft (B) is further supported by a cap (Al) bolted to the bracket (A,, and outside this cap a sprocket wheel (C) is mounted on the shaft, from which the power is transmitted by a chain to the road wheel sprocket. A brake drum (Di is also carried by the shaft (B). This gear is employed in duplicate, one at each end of the differential shaft (1).
No. 26,401, dated Dminibei 5th, 1904.Lubricator.—Fisher and another.—The cap (B) screws into the cup (A), which latter has a flange (a) provided with notches (E). On the cap is pivoted a spring-controlled lever (C) carrying a depending pin (DI. Whilst screwing the cap down, for the purpose of putting pressure upon the lubricant, the pin (D) does not prevent rotation, as when it drops int.) the notches (F) it again rises out of them, owing to the position of the lever (C), but it forms an efficient lock to prevent movement in the other direction—
that is, to unscrew the cap. For unscrew. ing the cap the spring may be arranged to keep the lever thrown back and the pin (D) out of engagement with the notches (E) when the lever has been moved through a given limit.
