RIVET.

Specification of Letters Patent.

Patented Apr. *7, 1914.

Application filed September 30, 1913. Serial No. 792,674.

To all whom t may concern Be it known that I, HERKEN H. I-IERKENS, a citizen of the United States, residing at Gilman, in the county of Iroquois and State of Illinois, have invented a new and useful Rivet, of which the following is a specification.

This invention has reference to improvements in rivets and is designed to provide a rivet which may be secured in place Without the employment of a hammer or a like tool.

In accordance with the present invention the rivet comprises a body member composed of a stem and a head thereon, and another head member related to the body member to be screwed thereon, the stem of the -body member being threaded and the separate head member being formed with a threaded socket, while the stem of the body member has a continuation beyond the threaded portion and the separate head has its socket portion terminating in a Haring groove into which the extended end of the stem of the body member is expanded, thus holding the parts so rmly together that they will not separate unless subjected to a twisting force the reverse of that by which the two parts are applied one to the other.

The invention will be best understood from a consideration of the following detailed description taken in connection with the accompanying drawings forming part of this specication, with the further understanding that while the drawings show a practical form of the invention, the latter is not confined to any strict conformity with the showing of the drawings but may be changed and modied so long as such changes and modifications mark no material departure from the salient features of the invention.

In the drawings z-Figure 1 is a section showing the improved rivet applied, some parts of the rivet being shown in elevation. Fig. 2 is a diametric section of the separable head of the rivet. Fig. 3 is an elevation of the body portion of the rivet. Fig. 4 is a plan view of the head of the rivet. Fig. 5 is a plan view of the body portion of the rivet as viewed from the stem side. Fig. 6 is a plan view of the body portion of the rivet as viewed from the side remote from the stem. Fig. 7 is a detail section of the free end of the stem of the body portion of the rivet.

Referring to the drawings the rivet is shown as composed of a body member 1 and a separate head member 2. The body member 1 consists of a stem 3 and an expanded head 4 corresponding generally to the stem and head ofV an ordinary rivet. The separable head 2 is indicated as plano-convex, although not necessarily of such form, but is made somewhat thicker, especially in its central portion, than a washer such as is provided for use with an ordinary rivet. The stem 3 of the body portion of the rivet is screw threaded for a portion of its length, as indicated at 5, while at the end of the screw threaded portion remote from the head 4 the stem has a continuation 6 formed with an axial entering socket 7 therein, and this socketed extension 6 is slit longitudinally at a suitable number of points, as indicated at 8.

The head 2 is provided on its plane face with a central internally threaded socket 9 extended for an appropriate distance t-oward the convex face of the head 2, and from thence there is formed into the head toward the convex face a plain flaring groove 10 of conical contour, thereby forming at the inner end of the threaded socket 9 a flaring boss 11 axially related to the longitudinal axis of the socket 9 and expanding therefrom. The convex face of the head 2 is provided with sockets 12 on opposite sides of its axis for the application of a pin wrench or other suitable tool, while that face of the head 4 of the body portion of the rivet remote from the stem 3 has an elongated recess 13 formed therein permitting the application of a screw driver or other proper tool.

In Fig. 1 there are shown two

members

14, 15, respectively, which may be taken as indicative of two structures to be united by the rivet, and specifically these two

members

14, 15 may be considered as two straps "of leather or plates or strips of metal to be joined together. As is customary, matching holes are formed through the two straps 2 of the rivet is applied to the threaded portion of the stem and screwed thereon toward the washer 16 and ultimately the screwing action will cause an engagement of the socketed extension 6 with the flaring boss 11. A continued screwing of the head 2 on to the stem results in expanding the slit end 6 into the flaring groove 10, t-he metal of the rivet bending outwardly in response to the applied forces. By the time the head 2 is seated in clamping relation to the body of the rivet and the

members

14 and 15 on the stem of the rivet, the slit end .6 has become firmly seated in the groove 10 and any force tending to separate the head 2 from the body of the rivet is resisted both by the screw threads and by the expanded end of the stem 3, so .that the rivet holds to the limit ofl the strength of materials employed. Should, however, it be desired to remove the rivet the head 2 has simply to be unscrewed, whereupon the expanded head 6 collapses toward its first po-sition and `no longer interferes with the linal removal of the head 2, so that the head may be used repeatedly until some part of t-he structure breaks.

What is claimed is l. A rivet comprising a body portion having a stem and a head at one end of the stem, and the other end of the stem threaded and formed with a continuation beyond the threaded part having an axial socket producedV therein, and a removable head provided with' a threaded socket for the reception of the threaded portion of the stem and a flaring annular groove at the inner end of the socket adapted to receive and spread the socketed continuation at the free end of the stem.

2. A rivet comprising a body portion having a stem and a head at one end o-f the stem, and the other end of the stein threaded and formed with a continuation beyond the threaded part having an axial socket produced therein, and a removable head proand a continuation beyond the screw threaded portion and there free from screw threads, said continuation being formed with an axial entering socket, and a separate head made thinner from the central portion toward the margins and at the central portion provided with a threaded socket havingV its inner end continued as a flaring annular groove free from screw threads and adapted to receive and spread the socketed free end of the stem.

4. A rivetcomprising a stem having a,

head formed at one end and at the other end provided with external screw threads and a continuation beyond the screw threaded portion and there free from screw threads, said continuation being formed with an axial rentering socket, and a separate head made thinner from the central portion toward the margins and at the central portion provided with a threaded socket having its inner end continued as a flaring annular groove free from screw threads and adapted to receive and spread the socketed free end of the stem, both heads of the rivet being provided with vmeans fo-r the application of manipulating tools. c

In testimony, that I claim the foregoin as my own, I have hereto affixed my signature in the presence of two witnesses.
