New Hudson Models for 1923

595 c.c. New Hudson 1922

A novel silencer fitted to the 595 c.c. New Hudson.

Externally and indeed internally the larger solo machine closely follows the 350 c.c. model.

595 c c. New Hudson Tank, 1922

Petrol and oil tanks are completely separate.

New Hudson 1922 Rear Brake

By inclining the grooves for the rear spindle and brake stop at certain angles the necessity for brake adjustment when tightening the rear chain is avoided.


New 350 c.c. and 500 c.c. of Neat Appearance and Clean Design.

FOR next year the 595 c.c. New Hudson sidecar outfit will be retained, with minor improvements which have been brought about as a result of the firm's experience throughout the year. The price will be still further reduced to the neighbourhood of £118 10s.

Except for certain refinements, the 87 x 100 mm. engine remains unaltered, but a new type of silencer with a simple but efficient baffle and fiat tail pipe, and cast aluminium chain guards, will now be fitted. A Terry saddle is now an item of the specification.

It will be remembered that salient features of this model, with which we dealt recently after a road trial, include good footboards and legshields, excellent mudguarding (now even further improved), a change-speed lever which passes through the tank in a particularly convenient position; all-chain drive with internal expanding brakes on both front and rear wheels, and a serviceable decompressor.

A further improvement lies in the Druid-pattern forks, which are now provided with an adjustment for taking up side play.

The standard sidecar has a well-built and roomy body with deep upholstery and a big locker. A family sidecar with child's seat in front of the passenger's seat can be obtained for an additional £12, and the outfit, complete with a de. lure body having hood, scuttle dash, screen, and side curtains, is priced at £135. All prices are provisional, and subject to slight modification.

In addition, a sports outfit, having a similar specification but plain D section mudguards, and footrests instead of foot-boards and legshields, complete with a smart aluminium sidecar, is listed at £125.

Perhaps the most interesting addition to the New Hudson range is a light solo machine which is equipped with an engine of 70x90 mm. (346 c.c.), side by side valves, and plain bearings throughout, special attention having been given to the lubrication of the bushes. A single cam operates both valves through specially designed rockers, and the valves are retained on their seats by double concentric springs.

Very deep circumferential cooling ribs with cooling towers in the valve caps and an internal exhaust lifter are features of the design. Chain transmission throughout and a new gear box of New Hudson design are employed. The chief features of the box are that ball bearings are used exclusively, and that the kick-starter operates direct through a lay shaft gear. The standard ratios provided are 5.6 to 1, 9 to 1, and 13 to 1. A dry plate clutch having bonded asbestos inserts provides the frictional connection. Both chains are protected by cast aluminium guards, and to absorb transmission shocks a Renouf type shock absorber is fitted to the engine shaft.

A further feature of some importance lies in the tank construction, the fuel and oil tank being composed of two separate units fitted together with a thick felt pad between. A short over-lap of the oil tank lends a neat appearance, and the advantages in the case of tank leakage are obvious.

The machine is priced at £70, or a similar machine turned out as a sports model without kick- starter, footboards, or legshields, at £75.

A larger edition similar in almost every detail employs a similar (79.5x100 mm.) engine to that used in the last Tourist Trophy races. The machine has 26 x 3/8 in. tyres, slightly wider guards, and more powerful brakes. Its price is £85.

The three-wheeled light car, which stands at the very top of its class, has undergone no modifications except the price; the sum of £195 now covers the complete vehicle with detachable wheels, spare wheel, electric lighting, etc.

NEW HUDSON. (142.)

Varied Single Cylinders.

2¾ H.P. Model.

70x90 mm. (346 c.c.); single cyl. four-stroke; side valves; mechanical and hand lubrication; Binks carburetter; chain-driven mag.; 3-sp. gear; clutch and kick-starter; chain drive; 650x65 mm. tyres. Price, £65.

New Hudson Ltd., Icknield Street, Birmingham.

The 346 c.c. New Hudson is an entirely new model, the engine being distinctly reminiscent of the firm's bigger power unit. The cylinder carries enormous radiating fins, whilst the gases are led away through an exhaust pipe of unusually large bore into an aluminium expansion box mounted just forward of the rear hub. The valves are no less than 1¾in. in diameter The cast aluminium chain cases are amongst the handsomest in the Show. Both brakes are of the internal expanding pattern. Following what is now standard New Hudson practice, the tank is made in two sections telescoping into each other, so that the partition is readily accessible should repairs become necessary. A 498 c.c. solo model is materially the same.

2¼ H.P. Model.

63x70 mm; (211 c.c); single cyl. two-stroke; drip feed lubrication : B. & B. carburetter; chain-driven mag.; 2-sp. gear; chain and belt drive; 24x2in. tyres. Price, £39.

The small two-stroke New Hudson is again offered in three forms for 1923, namely, the popular, sporting, and tourist models, which have proved so satisfactory that they remain unchanged except for the addition of footboards to the popular edition.

4.5 H.P. Model.

87x100 mm. (595 c.c); single cyl. four-stroke; side valves; mechanical and pump lubrication; B. & B. carburetter; chain-driven magneto; 3-sp. gear; clutch and kick-starter; chain drive; 700x80 mm. tyres. Price with Sidecar: £112.

This machine has earned such a high reputation in its class that any substantial alterations were obviously unnecessary. The steering head merits special study, being equipped at top and bottoms with ball bearings of unusually large size charged with sufficient grease to last the season. The firm's new pattern silencer now figures on this model. The rear side-car connection has been redesigned to eliminate twisting stresses. The tank is of the firm's special two-piece design.

Four editions of this model are offered, namely, standard, sporting, de luxe, and family, the latter being fitted with a double-seated sidecar. Special provision is made for positively adjusting the tension of the magneto and primary driving chains.
