Patented Feb. 29, 1944 UNITED STATES PATENT OFFICE Austin Gudmundsen, Milwaukee, Wis., assignor,

to Gudmundsen Stratton Laboratories, Inc., Milwaukee, Wis, a corporation of Wisconsin Application January 26, 1942, Serial No. 428,175

1 Claim. (01. 85-40)" This invention relates to rivets and riveting.

In many instances, where riveting is employed, as in metal airplane construction and in small sized tanks, space is not available for the dolly or anvil to be properly held against the head of the rivet while the rivet is being upset or headed.

It is, therefore, an object of the present invention to provide anovel rivet and method of setting the same which obviates the need for holding an anvil against the head of the rivet during the riveting operation and instead permits the setting operation to be completed entirely from in-front of the work.

With the above and other objects in view which will appear as the description proceeds, this invention resides in the novel construction, combination and arrangement of parts substantially as hereinafter-described, and more particularly defined by the appended claims, it being understood that such changes in the precise embodiment of the hereindisclosed invention may be made as come within the scope of the claim.

The accompanying drawing illustrates several complete examples of the physical embodiments of the invention constructed according to the best modes so far devised for the practical application 7 of the principles thereof, and in which: Figure l is a sectional view illustrating the rivet of this invention and the tool used for setting the same, with the rivet about to be set;

Figure 2 is a view similar to Figure 1 but showing the rivet set or formed;

Figure 3 is a view of the completed connection; Figures 4 and 5 are views similar'to Figure 3 illustrating slightly modified embodiments ofthe invention; and

Figure 6 is a perspective view of the rivet per se.

Referring now particularly to the accompanying drawing, in which like numerals indicate like parts, the numeral I designates generally a rivet constructed in accordance with this invention. The rivet is formed of suitably ductile metal and comprises a shank 6 with a head 'l at one end thereof.

Extending down through the head and into the shank is a well 8, the closed bottom of which is in the end of the shank remote from the head.

The mouth of the well is taperingly enlarged "as I at 9 to provide a socket for the reception of a pressure gun tip III. A thin-edged lip ll bounds the mouth of the wellto eifect a better seal with the gun tip,

In use, the rivet is inserted through the aligned holes in the two partsor plates I: to be secured together withthe head bearing against one of stand parts and theshank protruding beyond the 0 er.

The tip of the fluid pressure gun is then applied V tip of a shank expanding tool inserted into the to the socket 9 which forms the mouth of the well and a "shot" of fluid pressure from any suitable source is injected into the well. .This fluid pressure which may be hydraulic or pneumatic, expands the end of the shank to a. substantially bulbous sha e .as. shown in Figure 2 thereby clamping the plates or parts I! between the expanded portion and the head.

After being set or formed in this manner, the lip II is burnished or otherwise swedged over to provide a. substantially smooth outer surface as shown in Figure 3. Burnishlng over the lip ll closes the mouth of the hole or well as will be readily apparent.

In instances where added strength is necessary, a'shear reinforcing pin l3 may be driven into the well before the lip II is burnished over as illustrated in Figure 4. v

The invention is, of course, adaptable to flush type or flat headed rivets shown in Figure 5 as Well as it is to the round headed rivets shown-in Figures 1 to4 and 6.

From the foregoing description taken in connection with the accompanying drawing, it will be readily apparent to those skilled in the art that this invention provides a novel rivet and method of riveting by which the difllculties attending conventional riveting and resulting from cramped space conditions are eliminated and riveting from one side of the work is made possible.

Attention is also directed to the fact that the pressure employed in holding the fluid pressure gun against the rivet serves to firmly hold the rivet in place with its head snugly against the adjacent surface of the work during the setting enlarged portion or the well leads, the tapering wall portions of the lip and head providing a tapered seat of substantial axial length sumcient for good sealing engagement with the tapered taperingly enlarged mouth of the well, and said lip being adapted to be bent inwardly to close the mouth of the well and form a continuation of the top surface of the head.
