Super Cargo Bike ~ of 1898

Paging through issues online of the 1898 "Cycle Age and Trade Review" I found in the November 10, 1898 issue a remarkable article with two illustrations of what seems to be a monster cargo bike - but alas, by this time, this "cycling" journal was starting to include articles about various motorized vehicles as well.

COLUMBIA MOTOR CARRIERS

Pope Mfg. Co. of Hartford, Conn., has published a pamphlet describing the carrier vehicles shown in the accompanying illustration. The merchandise capacity of the vehicle is rated at 500 pounds under which it will give its regular speed and power. The structural strength, however, is sufficient to permit a load of 600 or 650 pounds, although under this extra weight the motor will not develop its normal speed. The form and design of the carrying bodies are not necessarily as shown, but may be varied to suit different requirements. The two styles illustrated show wide variation between a light motor truck wagon and a closed-up affair such as would be suitable for a dry goods establishment. The motor is a specially designed gasoline engine for which no water jacket or other cooling device is necessary, thereby saving many complications and much weight, says the company. A supply of gasoline which is sufficient for about 100 miles travel is carried in a tank attached to the frame between the boxes. Like all gas or gasoline motors, the first explosion must be obtained by physical effort, and bicycle cranks and pedals were adopted to give the desired result in the easiest and most satisfactory manner. By the attachment of a clutch with chain and sprocket to the shaft of the driving wheels, foot power may be used to assist the motor when on steep grades, obtaining higher speed than the auxiliary low gear of the motor would normally produce. When the cranks and pedals are not in use they remain stationary. The normal weight of this carrier vehicle is given as 750 pounds.

Pope was the manufacturer of Columbia bicycles (I was not familiar with this identity, "Pope Motor Carriers") and I had not realized the degree to which some of their motorized products were hybrids with their products as this one is. Of course this may only have been a design prospectus and never produced or sold.

It's an interesting idea, to have the pedals used for the kickstarter function to start the gasoline motor and then as a supplementary power source when useful.

Americans & Narrow Tires in the 1890s

It is not so easy to come up with certain kinds of historical information about cycling, but mass digitization of many out-of-copyright books has certainly offered up material to plow through looking.

Single Tube Cycle Tire (example)
The basic (really basic) view of the single-tube tire, popular in America

In reading Peddling Bicycles to America recently I came to understand that most Americans in the 1890s and into the 20th century used "single tube tires" but I really didn't understand much about them - But I then found Pneumatic tires, automobile, truck, airplane, motorcycle, bicycle: an encyclopedia of tire manufacture, history, processes, machinery, modern repair and rebuilding, patents, etc., etc. ... in Google books, by Henry Clemens Pearson, published by the India Rubber Publishing Co. in 1922. While it talks a great deal about car, truck, and other tires, it also has a section about bicycle tires.

It starts with this introduction:
History Of The Bicycle Tire

The history of bicycle tires has not been studied as carefully as it deserves, because the majority is not so much interested in historical development as in actual results. Inventors and a few who are students by nature may be interested, but they generally prefer to read their history at first hand, which is in the patent office reports.
Ah yes, actual results. After some discussion of this and that, it continues:
The Single-tube Tire In America

. . . Nevertheless, it was not the Morgan & Wright tire, built by tire specialists, but the Hartford tire [a single-tube tire], built by a bicycle manufacturing company, that ultimately triumphed in America. The reason for this lies partly in the love of Americans for fast riding and partly in their mechanical aptitude and ability to handle tools. While the Europeans were riding 2-inch double tubes, held on by wires in France, and by beaded edges in Germany, and by both methods in England, the tendency in the United States was wholly toward single tubes of even smaller diameters, it having been found that a small single tube, pumped hard, is the fastest of all for road use. The Tillinghast Tire Association, which controlled the manufacture of all single tubes, finally produced an article which represented the high-water mark in bicycle tire making, in resilience, cheapness, beauty and speed. For anybody with deft fingers, it was also the easiest of all to repair, and this fact appealed strongly to the American.
So, the theory that thinner tires inflated to a higher pressure will encourage going faster - lower rolling resistance - than fatter tires inflated less goes all the way back to the 1890s. (Of course this says nothing about the accuracy of the theory, just that it is of long standing.)

Fisk Single Tube

Then there are more somewhat complex ruminations about the European use of something other than single-tube tires . . . mostly included here for the slightly amusing categorization of the mechanical aptitude of various nationalities.
Though American single tubes invaded Europe and found hosts of friends, on account of their many virtues, the question of their repair could never be mastered by either the British or the Continentals. Could the Tillinghast Association have set up repair shops at convenient places throughout Europe, single tubes might have swept the world as they did America. Even despite hostile tariffs, they were sold in Europe cheaper than the home made kind. There were only 200 single-tube tires made in United States in 1891, while 1,250,000 were sold in 1896. In England the single tube was cultivated during the early years, the Avon Rubber Company being most successful; then, too, the W. &. A. Bates Company was using plugs for its tires in 1892; so that the repair of single tubes by the regulation method has been known in England as long as in America. The British are tolerably quick with tools, and the reason that the double-tube tire survived in the United Kingdom is probably to be found in the prevalence of hedge thorns on the English roads. These hedge thorn pricks are easily stopped with the thick repair fluids which were later developed here in America; and had the English known of this method early in the day, the single tube might have had a different history there. There are no hedges in France, and the avowed reason of the failure of the single tube there was the inability of the French to repair it. Another reason was probably due to the great influence of the Dunlop company there, no less than to the great growth of the Michelins. Even to this day, the wired-on tire is the dominant type in France.

The book then includes, apparently for amusement, a photograph of the largest tricycle in the world (and its tires) described in an earlier post - this photo is different than the one I used that came from a magazine of 1897.

It is of course difficult for the non-specialist (that is, me) to be sure I am understanding what is suggested by all this, but it is still entertaining on some level. The more things stay the same, the more things . . . stay the same. Or so it seems reading this.

Maxim Gun & Tricycle (1901)

Maxim Gun & Tricycle (1901)

From a Scientific American supplement article, 1901
BICYCLE ARTILLERY.

The bicycle artillery corps is a body of recent creation which seems to be destined for a great future. In fact, it is now in a fair way of doing reconnoissance duty in place of the cavalry. How much superior, indeed, is a bicyclist to a horseman. He is always ready to start immediately, while the latter has to wait to harness and saddle his steed. Then, again, the bicycle is faster than the horse, and requires less care; and the fact that no food is needed constitutes an appreciable advantage in a campaign in which so many difficulties are met with in the way of procuring forage. It is true that the bicycle can be used only upon roads, but in France and Germany the byroads, large and small, are so accessible that the use of it is capable of being made general.
. . . . .
Such considerations have led the large English house of Vickers, Sons & Maxim to devise a machine gun tricycle, which we represent in the accompanying engravings. Two Maxim guns are mounted upon the tricycle, the weight of which is 120 pounds, while that of the two guns is 54, that of the tripods 106, that of the spare pieces 8, and that of the 1,000 cartridges, with their case, 86. This constitutes a total weight of 374 pounds, to which is to be added that of the two men who ride the vehicle. It seems that such a tricycle is capable of running at a high rate of speed upon a level. Upon up-grades, however, it is necessary to dismount and push the machine.
