Not indexed. Not illustrated. 1886 Excerpt: . . . a standard taper for reamers for locomotive work includes an important class of work in which it is desirable to have uniformity. The taper used by railroad people in quite a number of instances is practically the same. The taper of-TV of an inch to the foot is now used on quite a number of the roads, though in some cases, whether intentionally or not, the standard is slightly different. In some cases I have known it to be a taper of only fa of an inch to the foot. Others have, and I know of one case in which the intention was to have the taper of an inch to the foot, but by some mistake the taper of the first set of gauges for reamers, instead of being fa to the foot, was fa. I think that fa of an inch taper to the foot, so far as we know from practice, is a good angle of taper for bolts which are required to hold together frames for locomotives, or, in fact, any such work. Mr. Coleman Sellers, in an address delivered before the Master Mechanics Association in Chicago, June, 1883, considered that the grinding of reamers, and the preservation of standard sizes in reamed holes for frame bolts, using gauges for the purpose, was made a much more simple operation by having a taper rather than a straight fit. The bolts are easily removed, and they certainly can be made to fit the entire length as well as if they were straight. In dowel pins the amount of taper per foot might be increased, and an angle represented by a taper of a quarter of an inch to the foot might be better for this purpose. Mr. Towne. --I may mention, in connection with this question, that the subject to which this relates has been very fully discussed in the proceedings of the Master Car Builders, and a reference to their papers would shed a good deal of light on it. No. 204. --17. The effect. . . This item ships from La Vergne,TN.<
