Claud Butler

LIGHTWEIGHT BICYCLES

Machines for Touring, Club Riding, Massed Start, Time Trial and Track Racing.

Choice of welded, brazed or the now world-famous C.B. bi-laminated frame construction.

New components, fittings and features exclusive to the Claud Butler range.

The cycle you want, the design you need to get the best out of yourself, the finish you like, the price you can afford.

Expert design service at your disposal for frames to suit your own angles and dimensions.

Claud Butler himself personally at your service at the C.B. works, through C.B. Depots in the London area or Agents and Dealers throughout Great Britain and the World.

FAMOUS NOT ONLY FOR RACING . . .

Claud Butler also produces the finest Touring, Club-riding and General-purpose models. These too incorporate those sound designs, special materials, exclusive features and manufacturing techniques which have been developed, tested and proved in the long succession of victories by C.B. riders in both classic and local events all over the world. And these riders continue to demonstrate with each fresh triumph the fundamentally superior technical ability and craftsmanship embodied in all Claud Butler bicycles.

“The Champions’ Choice”

[Front cover of the 1952 catalog, printed in red and black, with a red line drawing of a racing cyclist in a crash hat riding a drop-handlebar bicycle toward the viewer beside six red-starred selling points, under the large red script Claud Butler signature. A dealer has typewritten an imprint in black at the top, over the printed signature: “Your nearest Dealer :- Buntings, 107 The Parade, High Street, WATFORD.” with the town underlined. Two wire staples show at the left edge.]

TEAMWORK !

In introducing my 1952 Lightweight Catalogue, I contend it is the finest range of machines my fellow workmates and I have ever produced.

The very best use is made of modern high-class materials in the construction of these world-famous C.B. productions. . . . . From the conference room to the drawing office, to the machine shop, the frame building shop, the filing section, the plating and enamelling department, so through to assembly, inspection and final testing, packing and despatch—it’s an eye-opener in these days of haste (and a real contrast to “mess” production).

You are welcome to come along and have a chat to these craftsmen who take such a pride in building your machine. You only have to drop me a line saying when you would like to see what’s going on. You know we here are only vain mortals and like to show off at times—so please come and see us.

Now I’m not “coming the old soldier,” or “line-shooting,” nor is it “flannel” when I say (and others all over the world do also) that there is no country on the Continent or elsewhere that can hold a candle to us.

We here work as a team—there’s Anne who makes the tea, there’s “Smiler” who unloads supplies.

Take this catalogue, another team effort. We all have a say about what’s going into it.

Then there’s the girl who types answers to your technical queries and the cheerful soul who cleans up in the mornings, “Bill” who shuts up at night—all count in that harmonious team in producing the final happy result—the perfect Lightweight.

And don’t forget our long-suffering C.B. dealer whom you keep up half the night discussing your specification or the time you HOPE to put up on Sunday !

Cheerio—I’ll be seeing you,

Claud Butler

[Introduction page of the 1952 catalog, with a head-and-shoulders halftone photograph of a man in a suit, white shirt and patterned tie at the top left and a signed open letter headed “Teamwork!” wrapping around it. The letter closes with a facsimile of the Claud Butler script signature, printed in black on cream paper.]

Exclusive Features
of CLAUD BUTLER LIGHTWEIGHT BICYCLES

Every Claud Butler Lightweight has its numerous special features, some examples of which are given below. It is such imaginative conceptions, scientifically designed, brilliantly produced and proved sound by practical test, which demonstrate the go-ahead policy of this Establishment and provide one of the many reasons why Claud Butler is always in the lead.

C.B. BI-LAMINATED CONSTRUCTION

The greatest advance in frame building technique since the evolution of the “safety” bicycle. 25 per cent. stronger than the ordinary brazed joint, as proved by official N.P.L. tensile test. Enables me to build your frame to any desired angles (if practical) without lug “pulling.” Proved sound by practical demonstration on the roads and tracks of the World. (Including all post-war World’s Championships and Olympic Games series.) THIS IS THE TYPE OF FRAME CONSTRUCTION WHICH I RECOMMEND.

(1) AVANT-COUREUR SPÉCIAL BI-LAMINATIONS. As illustrated on left. Judge for yourself the attractive appearance, rugged strength, neat design and light weight of this Super bi-laminated frame jointing technique. Now standard specification on “Avant-coureur Special” and “Olympic Sprint” models.

(2) NEW ALLROUNDER BI-LAMINATIONS. As illustrated on right. The original C.B. design elaborately feature cut, bringing the advantages of this revolutionary bi-laminated technique within reach of all lightweight enthusiasts.

(3) C.B. WRAPOVER SEAT STAY TOPS. Originally introduced on C.B. Path models, this feature so effectively stiffens up the rear triangle whilst improving the appearance of the seat cluster that I now include it on the majority of road models as well.

(4) THE C.B. SEAT CLIP. Die cast in phosphor bronze, chromium plated and fitted with an effective 5/16″ dia. bolt and nut, this is by far the most efficient seat clip now in use.

(5) C.B. WORLD’S CHAMPIONSHIP SPRINT LUGS. Produced from really high grade steel throughout (including the bracket shell), these lugs, whilst being slightly thicker than the average pressed lug, are effectively and decoratively lightened by the very attractive cutaway feature, so building up a light but immensely strong brazed frame.

(6) C.B. UNIVERSAL CLUB LUGS. A set of strong lightweight pressed lugs, quite attractively cutaway, retaining strength whilst improving appearance and resulting in a first-class job at reasonable cost.

(7) C.B. SPECIAL GUIDE TUBE at bracket for exposed gear cable. By far the most effective method used for open gear cables on the market to-day.

(8) C.B. SPRING PUMP CLIPS. Here, again, C.B. in the lead ! Fastest possible release and replace with pump meanwhile safely and securely held in position without rattle. Clips themselves can be removed or replaced simply by removing one screw.

(9) C.B. PATH REAR ENDS. These rugged ends are but one of the many reasons why C.B. Path models are so widely used. Made of 9 S.W.G. 30 tons per square inch steel, a full 2″ slot makes provision for a wide range of gear ratios without interfering with total chain length.

At the top are two bi-laminated head-tube joints, the right-hand one carrying a partly visible script head transfer, followed by a seat cluster with wrapover seat-stay tops, two sets of lugs on short sample tubes, a bottom-bracket shell with a gear-cable guide tube, a spring pump clip on a tube and a track rear fork end.]

Craftsmanship —

Craftsmanship is exemplified in the versatility of the C.B. organisation. During the war years, for instance, bicycle manufacture was curtailed in favour of Aircraft and Radar Equipment production. Of more general interest are the machines illustrated below. If you want anything “tubular” ask Claud Butler to quote.

UNICYCLES

This is one I made for the famous Moxham Trio. I also make small ones with cranks mounted on the wheel spindle, or larger ones with countershaft drive. The tallest unicycle I have made (so far) was one 12 ft. high !

POLOBIKES

Designed and built to the ideal specification as a result of personal experience on the polo field in actual league competition. Not the cheapest polo machine you can buy (although quite moderately priced) but certainly the best.

PACE-FOLLOWERS

Built to U.C.I. and/or N.C.U. regulation dimensions. As used in successful record attempts and competition at home and abroad. C.B. pace-following machines are preferred by the majority of well-known riders whose names, for reasons you are well aware, cannot be mentioned here.

TRIPLETS AND QUADS!

Multiple seat machines are a speciality of the C.B. establishment. Three-seaters, Four-seaters, yes, and even Five-seaters built by C.B. may be seen on the roads of the world doing yeoman service, from Wyoming to Glasgow and from Bristol to Madras. Claud Butler will gladly quote you on hearing your requirements.
