Puncture stops innumerable have been devised, patented, and bought, and never just a few riders have as well as, privately experimented with sugar cures, glycerine, treacle, and different glutinous or viscous supplies inserted in a fluid state inside the internal tubes.
A few of these dodges, and a few even of the patented and comparatively expensive preparations, do unquestionably seal minute punctures, however not certainly one of them escapes the disadvantage of being messy and giving an enormous quantity of hassle when a big minimize or a severe wound happens. Taking all factors into consideration, it’s preferable to have a clear and dry air tube to 1 that exudes sticky matter when gashed.
However a brand new preparation is now being bought which differs from puncture stops and isn’t correctly classed with them. It’s a cowl cease, not a preparation for insertion in air tubes. Usually cautious riders endeavour to observe the directions of compilers of handbooks of recommendation to cyclists and insert wedges of rubber or cotton wool soaked in answer within the extra lethal cuts of their tubes, however these plugs are by no means everlasting and at all times somewhat unsatisfactory.
The brand new Westwood tyre is meant to switch these makeshifts and apparently solutions extraordinarily effectively, though the current experiments in a single tyre don’t conclusively show its sturdiness. The preparation is a compound of rubber which when uncovered to the air hardens and seizes surrounding rubber as if vulcanised collectively. If the minimize in a canopy is cleaned not solely of filth however of the sulphurous movie additionally, exactly as the within of a tyre is cleaned earlier than one places on a patch, and if a wad of this cowl stopping is then pressed into the minimize, kneaded fastidiously into intimate contact with the cleaned edges, and left for a [while] the stopping hardens, the opening is neatly crammed, and the evil scent of the answer disappears. Customers should be cautious to maintain the stopping coated within the tin or it should harden and turn out to be ineffective.
Mr Dunlop talks in regards to the pneumatic tyre
An fascinating account of an interview with Mr JB Dunlop, by Mr MMD Bodkin, KC, seems in The Bike owner, detailing the circumstances which prompted the inventor to plot air tyres. His eight-year-old son minimize up the gravel paths on moist days together with his solid-tyred toy tricycle wheels, and, as an indulgent father, he stated, ‘‘Sooner or later, my boy, I’ll make you wheels that might be sooner than any on the town.”
Mr Dunlop needed to redeem his promise. “I used to be accustomed,” he says, “to work with rubber, however there was no tubing available of the type I needed, so I received a sheet of rubber and a few answer and made a tube myself. The nice secret of such work, which puncture-repairers even but can’t at all times perceive, is to get the rubber fairly clear and to rub within the answer laborious. I did each, and presently I had an air-tight tube spherical my wheel, with a little bit of the tubing of a feeding bottle protruding for a valve. However the pneumatic tyre was not but full. If I had pumped air into it in that situation it might have blown out like a balloon until it burst. I appealed to my spouse. Thankfully she had precisely what I needed. She received me a strip of outdated costume of wonderful gray linen that had been trendy in its day. A strip of this linen I pressed over the rubber tube and tacked it neatly and tightly to the picket wheel. Then I pumped the air in with my boy’s soccer pump, folded and tied the top of the little bit of feeding-bottle tubing, and so the primary pneumatic tyre the world has ever seen was made and inflated.”
The home image of the inventor thus urgent into service the objects prepared at hand is most fascinating.
