Abstract
177,442. Wheeler, J. A. June 9, 1921. Nuts; locking nuts; bolts.-A concavo-convex nut is secured to a bolt on flattening with a hammer, and is provided with h an interrupted thread of special construction which bites into the bolt. The nut 10 has a central hole 11 from which a number of slots 12 radiate. The central hole 11 tapers from the convex side 13 to the concave side 14, and has threads in the form of ratchet teeth having faces B<1> parallel to the nut faces and inclined faces 16 extending outwards towards the concave face of the nut. When the nut is flattened into engagement with a bolt, the slots 12 tend to close and form a continuous biting-surface. To tighten a bolt, the nut is further hammered, but to remove the nut a spanner is used in the ordinary way and the nut acts as a die. The nut can be used for forming a bolt-head, in which case a special form is employed in which the slots 12 are wider towards the centre in order to bite longitudinal ridges on the bolt when flattened, and prevent rotation. The nuts may be employed with piping &c. Another form in which the nut is shaped as the fastener of a cone is described, wherein the nut is forced into engagement with a rod by means of a hollow tool having a convex under face.
