This patent application is a division of my patent application Serial No. 475,929, filed February 15,1943, now Patent No. 2,389,965.

This invention'relates to a method of making clips that are used to hold suspended articles in position. f

The principal object is to provide an improved method of assembling and fastening the. base and shank of a said clip together, that is simple, economical to accomplish and most durable.

The foregoing and other objects which will appear as the nature of the invention is better understood, may be accomplished bya method such as is disclosed by the specification. The. nature of the invention is such as to render it susceptible to various changes and modifications, and, therei'o're, I am not to be limited to said disclosure; but am entitled to all such changes therefrom as fall within the scope of my claims.

In the drawings:

Figure 1 is a perspective view of the base and shank of my clip before they are assembled and interlocked. v

Figure 2 is a front elevational view, partly in section, showing the shank tongue in position ready to be forced into locking engagement with the base of my clip by two dies.

Figure 3 is 'a front elevational view, partly in section, showing the shank tongue interlocked with the clip base, upon completion of'the final step in my method. 2

Figure 4 is a persp tiv clip. r Figure 5 is a plan view of the female dieused in the aforesaid method. I

First I will describe the parts of my clip, which, as illustrated, has a, flat base l0. Two slits .l I spaced apart are cut therein between which a portion of said base is thereby forced outwardly view or my completed to provide what I call an offset portion I2. .This.

leaves a space I3 directly opposite said offset which space is laterally opposite adjoining portions of said base. When used to hold insulating material in place next to a ceiling or wall said base usually has cement applied to it thus adhesively holding it to said wall or ceiling. The base has relatively large surface area to 1 provide a strong adhesive Joint between saidbase and said ceiling wall.

Attached to said base I is a'shank "having at one end extremity a tongue portion I! extending at a right angle. The other end extremity has a slot it which extends about half the length of said shank. On each side of said slot It fingers l1 arethereby formed. When my clip is in posia cam. for. art-14a) tion of use, said fingers I! {extending through the insulation and are bent over at a rightangle to lie approximately flat against said insulation.-

In practicing my method said locking tongue l is inserted into saidspace. l3 opposite said offset portion l2, andextends beyond said space l3 and overlaps aportion of said base 10. To interlock said tongue l5 with said base I0 I provide a female die especially shaped for the purpose, having a bulge 2i narrower than, but which fits against said offset portion I2 forthe length thereof. .A flat male or hammer die 22 strikes against a portion of said base Ill with such force that the part of said offset portion I! in contact with said.

female die bulge 2| is deformed and driven inwardly against said base tongue l5 which deforms and forces part of said tongue to enter said space li'thereby interlocking said tongue and base. It will be noted in Figure 3 of the drawings that an intermediate portion of said offset portion I2 is sunk inwardly as a result of the force of the hammerlike blow to thereby form a longitudinally extending channel therein and this is likewise I true of said tongue,

' What I claim is:

1. The method of making a clip having a shank embodying a flat tongue at one extremity extending at substantially a right angle to the adjoining portion, and having a base having two slits in an intermediate portion therein spaced apart. said base having an offset portion between said two slits thereby leaving an adjoining space between said ofiset and adjacent portions of said base, inserting said shank tongue into said space and holdingv a. female diehaving a bulge therein thatis of less width than said oflset portion with said bulge bearing against a laterally intermediate part of said offset portion while forcibly striking a surface of said base towards said off- 1 set portion and tongue to thereby distort said ofiset portion and said tongue and interlock them and cause a portion of said tongue to enter that part of said space that is laterally opposite adjoining portions of said base and force a portion of said tongue substantially'level with the surface of said base that was struck.

2. The method of making a clip having a shank embodying a tongue at one extremity and a base having two slits therein spaced apart, said base having an offset portion between saidtwo slits thereby leaving an adjoining space between said offset and adjoining portions of said base, inserting said shank tongue into said space and stationarily holding a female die against said offset portion while strikinga portion of said base forcibly to thereby distort said oflset portion into encasement with said tongue and simultaneously substantially filling that said space with a portlon at said tonsue. v
