Book Description
Excerpt from Report of Draft Gear Tests: United State Railroad Administration, Inspection and Test Section When gears were tested under this requirement, it was found that no useful information was obtained. Gears of widely varying characteristics and excellence passed the prescribed test and it was soon appreciated that the specification requirement as well as this test were useless in obtaining draft gear information. When this absolute dearth of reliable knowledge on the subject was fully realized by the Committee on Standards and the Purchasing Committee, they joined in requesting the Inspection and Test Section of the Division of Operation to conduct such a series of tests as would determine the mechanical value of each make and type of friction draft gear then regularly offered for sale to railroads. In addition to the various tests which have been completed and which are given in the report, the Section had definite plans made for train Operation tests and service tests. Had the time been available and had circumstances permitted, the Section would have completed these tests. It is much to be regretted that conditions on the railroads throughout the country during the war and immediately thereafter prevented the carrying out of these tests and this, to a degree, Operates to render the present work inconclusive. The information covering the tests which have been made on new gears is definite and final. To a limited degree, tests were made on gears which had seen considerable service but the service tests themselves and the train operation tests were not made for the reasons given. It is much to be hoped that arrangements will be made to complete the full series outlined by the Section and thereby render available accurate information concerning, the action of gears in train operation and the ability of each type of gear to stand up in service. With this added information, mechanical officers and purchasing agents would be able to equate value and cost and to understandingly purchase a definite amount of protection for a definite amount of money. If the present report does no more, it gives reliable and entirely comparable and unbiased values for new commercial gears of the various types. The values given should supplant the widely variant figures frequently given out in the past as a result of inaccurate, unscientific or incomparable tests.
