1 Claim. (c1. 151-4112 This invention relates to the mounting of nut-like members in connection with suitable supports, having specially shaped apertures for reception of a rectangular portion of a nut-like member and, wherein, said rectangular portion is peened-over to engage at least the major portion of the boundary walls of said aperture and, particularly, onto lands on the support arranged adjacent corners of said rectangular portion.

The novel features of the invention will be best understood from the following description, when taken together with the accompanying drawing, in which certain embodiments of the invention are disclosed and, in which, the separate parts are designated by suitable reference characters in each of the views and, in which:

Fig. l is a plan view of a part of a support showing one of my improved nut-like members attached to the support, the view looking in the direction of the peened side of said member.

Fig. 2 is a section on the line 2--2 of Fig. 1, indicating, in dotted lines, the normal contour of the rectangular portion of the nut member employed.

Fig. 3 is a partial section on the line 3-3 of Fig. 1.

Fig. 4 is a partial section on the line 44 of Fig. l; and

Fig. 5 is a view, similar to Fig. 1, showing only the support and indicating, in dot-dash lines, the rectangular portion only of the nut-like member.

To illustrate one adaptation and use of my invention, I have shown, at 111 in the accompanying drawing, part of a support of any type or kind and this support has, in an area thereof, a depressed or offset wall 11, as clearly noted in Fig. 2 of the drawing, which forms a substantially circular recess 12 on one surface of the support.

The wall 11, note Fig. 5, has a generally circular aperture 13 therein and spaced about the periphery of the aperture are substantially semi-circular recesses 14. The recesses or notches 14 are four in number and so spaced as to receive corner portions 15 of an angular or rectangular portion 16, indicated in dot-dash lines in Fig. 5 of the drawing, of a nut member 17, said member being shown in cross-section in Fig. 2 of the drawing. The portion 16 is on one side of the member 17 and extending from opposed sides of the portion 16 are flange extensions 18, which are within boundaries of the other opposed edges of the portion 16, as will clearly appear from the dotted line showing of 18 in Fig. 1 of the drawing.

It will appear that, when the rectangular portion 16 is positioned in the aperture 13 and the notches or recesses 14, the wall 11 will have pairs of lands 19 arranged closely adjacent angular sides of the rectangular portion 16 adjacent the corners 15, as clearly noted in Fig. 5 of the drawing.

Fig. 4 of the drawing shows a sectional view through one of the lands 19 to clearly indicate the extent of engagement of the peened-over portion 20 on each of the lands. In other words, the rectangular portion 16 is peened to extend and flare the metal to extend not only over the lands 19, but in contracted portions beyond the notches or recesses 14, as indicated at 21 in Figs. 1 and 3 of the drawing. It will also appear that portions of the peened metal will also extend onto the wall 11 intermediate the pairs of adjacent lands, as is indicated at 22 in Figs. 1 and 2 of the drawing.

The peening operation will leave, centrally of the upper surface of the rectangular portion 16 as noted in Figs. 1 and 2 of the drawing, an annular projecting ring or collar 23, the thickness of which will depend entirely upon the extent of peening of the metal, it being kept in mind that, in some instances, the metal may not be peened over sufficiently to overlie the wall 11 at the positions 22, noted in Fig. 1 of the drawing, the important thing being to establish a positive locking engagement of the member 17 with the wall 11 of the support, at least upon the lands 19 and around the notches or recesses 14. The member 17 has a suitably threaded bore 24 for reception of a bolt or other fastener.

It will appear that the lands 19, in addition to providing relatively large surfaces for engagement of the peened-over metal, particularly as seen in section in Fig. 4 of the drawing, also provide means for definitely retaining the nut member 17 against any possible rotation and this will readily appear from a consideration of Fig. 5 of the drawing, where the inwardly extending portions of the lands are shown in close proximity to outer surfaces of the rectangular portion 16.

It will be apparent, however, that where the lands 19 are located over the projecting flanges 18, the wall 11 is actually pinched or compressed between the peening 20 and the flange 18.

By virtue of the structure and method of procedure followed in attachment of the nut-like member to a support, the desired end result can be accomplished simply and economically with assurance of positive engagement of the member 17 with the support in retaining the same against displacement, regardless of the stress or strain to which the member 17 may be subjected.

Having fully described my invention, what I claim as new and desire to secure by Letters Patent is:

The herein described means for mounting a nut member having a threaded bore in connection with a support, the support having a wall with a circular aperture therein with four circumferentially spaced notches projecting outwardly at the periphery of said aperture, the notches forming, on said wall, four pairs of circumferentially spaced lands, a nut member having a square end portion defining four circumferentially spaced corners adapted to be arranged in said four notches in positioning the square end in said circular aperture, spacing of opposed fiat sides of said square end portion being materially less than the diameter of said aperture, said pairs of lands engaging surfaces of said corners in definitely keying the nut member against rotation in said circular aperture, the other end of said member being enlarged to engage one surface of the apertured wall of the support, part of said square end being circumferentially peened-over to engage the other opposed surface of the wall and upon the lands adjacent the notched portions of said wall in fixing and keying the nut member to said wall, and the remaining part of the square end of the nut member defining a round ring bordering the threaded bore of said member.
