R. s. PEIRCE IIAITACHING DEVICE Sept. 1, 1931.
Filed Nov; 16. ,1928
Patented Sept. 1, 1931 PATENT OFFICE RALPH S. PEIRCE, OF HINSDALE, ILLINOIS ATTACHING nnvlon Application filed November 18, 1928. Serial No. 319,805.
My invention relates to attaching devices of the class employing bolts and object holding elements in the form of bars along and against the sides ofwhichthe bolts are hammer driven. Such bars are provided with object holding flanges at their outer ends, these flanges lapping portions of the wall or other support which surround the holes that receive the bars. The objects to be supported are usually interposed between the flanges and wall.
In accordance with one feature of my invention such a bar is formed with a continuaion at its inner end which is folded beside the body of the bar, there being bonding material between said continuation and the body of the bar to obstruct separation of these two parts. This bonding material is desirably furnished by hot galvanization of the parts that are to be bonded. i
In accordance with another characteristic of the invention the continuation of the bar is folded upon itself and beside the body of the bar. In this preferred embodiment of the invention the bonding material is not only interposed between the body of the bar and the adjacent portion of the bar continuation but is also desirably interposed between the adjacent face portions of the folded continuation itself.
In accordance with another embodiment of the invention the attaching device is inclusive of two object holding bars placed abreast, the inner ends of the bars being connected by a web that constitutes a continuation com mon to and integrally formed with the bars, this web being desirably folded upon itself and having its folds bonded or cemented together and which web is also bonded or cemented to the bodies of the bars. By cementing or bonding the bodies of the bars and their continuations as described such continuations may be made of lighter construction than would otherwise be practicable. Undue rupture between the bars and their continuations consequent upon the driving of fastening bolts into the holes containing the bars is also guarded against by the bonding or cementing described.
The invention will be more fully explained in connection with theaccompanying drawings in which Fig. 1 is a perspective view illustrating an initial step which is preferably taken in forming the bars and their connecting web; Fig. 2 illustrates a succeeding step in the formation of the connecting web; Fig. 3 illustrates a third step in the formation of the bars and connecting web; Fig. 4 is a perspective view illustrating the completed device the hammer driven bolt being shown apart from the bars between which the bolt is to be driven; Fig. 5 is a longitudinal sectional view showin the bar structure of Fig.
l inserted within a hole or recess that is formed in a wall or other support, the bolt {1 that is to be hammer riven between the bars being shown beside said hole or recess but in alignment therewith; Fig. 6 shows the structure'of Fin. 5 excepting that the bolt is shown as being driven into place to force the inner end of the bar structure into tight engagement with'the surrounding wall with the recessor wall that contains such bar structure; and F ig. 7 is a sectional View on line 77 of Fig. 5.
The bars 1 and 2 of a single attaching device are preferably formed of sheet or strip material with connecting web 3 of reduced width in integral formation with the bars as illustrated most clearly in Fig. 1. 'This web constitutes a continuation which is common to andinintegral formation with both bars. The web has its end portions folded upon themselves lengthwise of the bars, the bights of the folds extendingcrosswise of the bars, as illustrated in Fig. 3. In Fig. 3 the bodies of the bars are curled into cylinder segments and the mid-portion of the web is formed at its ends with depressions 4. The web is next folded into U form illustrated in Figs. 4 and 5, the side portions of the U beingbetween the bodies of the bars and being laterally and rearwardly hent to provide portions 5 that are next to the bodies of the bars. The structure thus finally formed is in the nature of a s eeve whose rear end is substantia ly closed by the connecting" web that joins the two halves of the sleeve and whose outer end is open to permit the bolt 6 to be received in the sleeve. lhe two halves or bar portions 1 and 2 of the sleeve are formed with lateral projections or flanges 7 which lap the portion of the wall support 8 that surrounds the recess 9 in the wall or support that contains the sleeve. The object to be supported is shown with a portion 10 between the flanges 7 and the wall 8. The belt 6 is desirably tapered at its inner end as indicated at 11. The tapered end of the bolt enters the depressions d in the web 3 and serves to spread the web apart from the shape shown in Fig. 5 to the shape shown in Fig. 6. The inner end of the bars 1 and 2, that is the inner end of the sleeve comprised of these bars, is forcibly expanded by the hammer driven bolt to firmly grip the surrounding portion of the wall 8.
After the sleeve port-ion of the fastening device is formed as described and illustrated in Fig. 1-, I immerse the same in molten zinc with the result that the adjacent faces of the bars 1 and 2 and the connecting web between them are bonded or cemented together as are also the adjacent faces of the mid-portion of the web w iereby the bars and webs are maintained in assembly and rupture between the web and the bars is obstructed. Galvanizing material also enters the spaces between the longitudinal edge portions of the bars to normally maintain these edge portions together, a feature of advantage in storage and transportation. I am enabled by means of the galvanization of the bars together along the longitudinal edges to maintain the given diameter for the bores of the sleeve comprised of the bars and which may be of just a size which will permit the bolts to be received within and frictionally held by the sleeves, also an advantage in storage and transportation, it being understood that when the bolts are thus held in assembly with the sleeves that they are not forcibly entered between the two halves of the sleeve. The bonding material, however, may readily be ruptured by the action of the bolt when driven between two halves of the sleeves and between the sides of the middle fold of the web. The cementint: of the folds and the web together preserves these folds in bonded relation except where the bolt enters the mid-portion of the web, whereby the rupture of the web from the two halves of the sleeve is guarded against and whereby a web may be employed of lighter construction than would otherwise be permissible.
Having thus described my invention, I claim:
1. An attaching device including two object holding bars placed abreast and each having an object engaging flange at one end that is to be outermost, the inner ends of the bars being connected by a web that is integrally formed therewith; and a hammer driven bolt passed between and forcibly pressing laterally against the opposed sides of said bars to spread the bars apart, wherein the web is folded by being returned upon itself to thicken it and the hammer driven bolt presses laterally against said web where folded.
2. Thestructure of claim 1 wherein the folded portion of the Web is passed between the bars and is positioned to be pressed upon laterally by the hammer driven bolt.
3. An attaching device including two object holding bars placed abreast and each having an object engaging flange at one end that is to be outermost, the inner ends of the bars being connected by a web that is integrally formed therewith; and a hammer driven bolt passed between and forcibly pressing laterally against the opposed sides of said bars to spread the bars apart, wherein the web is of U form, side portions of the U being between the bodies of the bars and laterally and rearwardly bent and continuous with the bars respectively adjacent thereto.
4. The structure of claim 1 wherein the web, where folded, is provided with bonding material between adjacent face portions of the folds in the web.
5. The structure of claim 1 wherein bonding material unites adjacent face portions of the web and bar.
6. The structure of claim 1 wherein bonding material unites adjacent face portions of the web and bar and adjacent face portions of the folds in the web.
In witness whereof, I hereunto subscribe my name.
RALPH S. PEIRCE.
