All bolts were supplied in quantities and proportions determined by following the proportions of the scientific tariff. They were shipped to France in these proportions, whence reports from the American Expeditionary Forces showed that the quantities sent completely covered the needs of the troops in the field. The saving in the manufacture of bolts alone came to nearly $4,000,000, and this says nothing of the saving in railroad and ocean freight charges, or the still more important saving in ocean tonnage space, since the bolts supplied according to the scientific tariff occupied many hundreds of cubic feet less space than the bolts originally specified would have filled.
The same procedure was followed in the supplying of files. The hardware manufacturers consulted their records and on the basis of actual consumption in American industry discovered that a repair unit consisting of a machine shop, a horseshoeing shop, a blacksmith shop, and a woodworking shop, with 11 mechanics working in the unit, would consume 305 dozen files per year, the experience tables showing precisely the proportions of the various sizes of files in this consumption. Consequently, when the American Expeditionary Forces requested 439,200 dozen files, the quantities of each size, kind, and style as specified in the requisition from France were disregarded, and the so-called tariff proportions substituted. The files as supplied not only proved adequate in number in every style, but they cost $250,000 less than it would have cost to fill the original order. Moreover, by using tariff sizes the industry was able to make immediate shipments and to run at full production from the start, since it needed only to produce files in the proportions known in the regular trade.
What was done with bolts and files was done in many other lines of hardware. When the American Expeditionary Forces saw that its hardware was coming in correct quantities, its officers notified the hardware supply organization to ship all tools and hardware materials in accordance with the so-called tariffs. The executive committee of the Hardware Manufacturers' Association for War Service, which made possible this achievement in commercial science, consisted of Messrs. Murray Sargent, Alexander Stanley, Charles W. Asbury, Fayette R. Plumb, and Isaac Black.
The standardization of proportions in the hardware supply succeeded in cutting an original requisition of the American Expeditionary Forces for 8,750 tinners' machines to 860, and an original requisition for 21,600 tinners' assorted groovers to 240, and still met every need of the Army's tin shops in France.
The Army hardware office was also called upon to supply such small hardware as fasteners for gas-mask knapsacks and pistol holsters, and some metallic parts for cartridge belts and similar goods. Less than two months before the armistice was signed orders were in sight for the manufacture of some 500,000,000 pieces of these small metallic devices. Most of them were to be made of brass. The uses of the Army in October, 1918, were calling for these articles in such quantities that it required approximately 250,000 pounds of brass per working day to meet the demand.
