    Abstract: A method and fastener assembly for preloading a joint wherein a pin having a shank and a head at one end is disposed with the shank portion passing through aligned apertures of a plurality of workpieces to be joined. The shank portion of the pin extends beyond the surface of the workpiece and is provided with an irregular surface configuration. A deformable collar having an initially smooth surfaced internal bore is disposed about the pin and snugged against the adjacent workpiece by a removably positioned means placed in abutting relationship against the free surface of the collar to lightly clamp the joint assembly together to remove free play in the joint. The collar is radially inwardly deformed by a crimping tool so that the initially smooth surfaced internal bore of the collar is deformed to assume a configuration complimentary to the irregular surface configuration of the pin shank and upon continual application of the crimping force an axial elongation of the collar and the shank of the pin is effected to provide a predetermined tension or preload on the joint assembly. After the collar has been deformed, the means to snug the joint together initially is removed.

    Abstract translation: 一种用于预加载接头的方法和紧固件组件，其中在一端具有柄和头的销被布置成使得柄部穿过待接合的多个工件的对准的孔。 销的柄部分延伸超过工件的表面并且设置有不规则的表面构造。 具有初始平滑的表面的内孔的可变形的套环围绕销设置并且通过可拆卸地定位的装置紧贴在相邻的工件上，该装置被置于与套环的自由表面邻接的关系中，以轻轻地将接头组件夹紧在一起，以消除在 联合。 套环通过压接工具径向向内变形，使得套环的初始光滑的表面内孔变形以呈现与销柄的不规则表面构型互补的构造，并且当连续施加压接力时，轴向伸长 套筒和销的柄部被实现以在接头组件上提供预定的张力或预载荷。 在衣领已经变形之后，最初将连接在一起的手段被去除。

    Abstract: 984,819. Making semi-conductor housings; jointing by forging. STANDARD PRESSED STEEL CO. March 14, 1961 [Jan. 23, 1961], No. 9284/61. Headings B3A and B3H. [Also in Division H1] A method of cold interlocking two members 20, 10, Fig. 1, of different plasticities in end to end engagement, Fig. 4, comprises providing the harder member 20 with a lateral flange 21 and annular recess 24 and cold pressing it on to the softer member 10 whereby the latter flows into and fills the recess and the flange 21 is locked therein under elastic stress. In the manufacture of a semi-conductor such as a silicon rectifier, Fig. 4, a semi-conductor wafer 30 is soldered at 15 to a copper base 10 which has been plated with gold or silver, a lead 31 is soldered to the wafer and a covering of lacquer or latex 33 is applied. An annular recess 11, Fig. 1, in the base receives the flanged end 21 of a steel cap 20 and pressure is then applied in a mechanical or hydraulic press to cause cold flowing of the copper into the recesses 24, 26 thereby producing a hermetic seal. Flange 23 limits the penetration. The flange 21 is bent upwardly upon engagement with the bottom of the groove 11 and locked by the flowing metal under elastic stress. A glass seal 35 is then crimped around the lead 31. In other embodiments, Figs. 10-12 (not shown) two annular recesses 24 are provided in the steel cap and gaskets may be fitted. In another embodiment, Figs. 7, 8, 9 (not shown), a soft tube is interlocked into a solid or hollow hard metal base provided with a flange and annular recess. A separate anvil may be used to deform the flange 21, Fig. 7 (not shown).
