Lincoln Elk.
A new Lincoln Elk with selective clutch gear on the counter-shaft.
Kirby and Edwards will have a comprehensive exhibit of ten Lincoln-Elk machines at Stand No. 84. The model A is a 3½ h.p. machine fitted with the firm's own 85 x 88 mm. engine, Bosch magneto. B. and B. carburetter, and Druid spring forks. Palmer tyres are fitted, and this model will be supplied with the Lincoln-Elk two-speed gear and free engine, free engine clutch alone or fixed gear. The 3 h.p. model B has a 79 x 82 mm. engine and the same specification as above. The 2¼ h.p. model C is a lightweight, 70 x 72 mm. engine, and is sold at a remarkably low figure. All machines are manufactured complete on the firm's own premises. Visitors to the Show should not fail to inspect the new two-speed gear and free engine clutch, which are also made in the same factory and claimed to be novelties.

LINCOLN ELK, No. 84.
James Kirby, Broadgate, Lincoln. – This machine follows standard lines throughout. The frame is dropped at the rear, where it is interesting to note that an additional stay runs from the gear bracket to the saddle tube, Druid forks are provided. The two-speed model is interesting, as it is partially chain-driven. The gear is carried on the counter-shaft, and the change is effected by means of external expanding clutches. On the high gear the drive is by chain to the counter-shaft, and thence by belt to the rear wheel. On the low gear the belt pulley on the counter-shaft runs free, and the drive to the rear wheel is by chain.
A lightweight model, B. and B. carburetter, belt drive, ordinary type frame, is a neat-looking standard machine which follows accepted lines throughout.

2¼ h.p. Lightweight, 3 h.p., 3½ h.p., and 4¼ h.p. Models: 70x72, 79 x 82. 85x88, and 89x96 mm.; side by side m.o.v.; B. and B. carburetter; two-speed counter-shaft; belt and chain.
J. Kirby, Broadgate, Lincoln.
The four models specified above are all single-cylinder machines, the lightweight being the only model to which the two-speed gear, mentioned in our issue of the 21st inst. (page 1329), is not fitted. This counter-shaft is a remarkably compact design; it is driven from the engine by a chain, protected by a neat sheet aluminium cover, and on the high gear drives through a belt on the left side of the chain, on the low gear through a chain on the other side of the wheel. High and low gears are each fitted with a separate clutch, which is simplicity itself, consisting merely of a split bronze ring of good bearing surface, contracted by the operation of a side cam so as to grip tightly and transmit the power.
As the diameters of these rings are considerably less than four inches, the clutches are very compact, and the side cams are worked by a single lever carried up the side of the tank.
A feature in the 4¼ h.p. model is the stay brought down from a point on the seat-pillar below the tank to the bridge joining the lower back wheel stays. A coachbuilt sidecar is shown in conjunction with the 3½ h.p. Lincoln-Elk, while a 4¼ h.p. machine is fitted with a new sidecar made by Bey, of Hampstead.
In this model the sidecar wheel is practically given a separate spring suspension, working as it does on the end of a lever pivoted to the sidecar axle and controlled by strong helical springs. The design is quite new, but we have not tried it.
