Sept. 3, 1935. A. BROOKE FINISHING BEADING, MOLDING AND THE LIKE Filed Feb. 1'?, 19321 Patented Sept. 3, 1935 FINISHING BEADING, HOLDING, AND THE LIKE Alec Brooke, Coventry, England Application February 17, 1934, Serial No. '111,762 In Great Britain May 23, 1933 Claims. (Cl, 155-184) depth of the material to which the attachmentl is to be made is insufficient-to aiord a secure hold ,10 for ordinary nails. Such cases occur where the substructure of the article to which the attachment has to be made is of metal covered with a thin layer of wood or the like.

The invention consists in the combination or association with headings, edgings, moldings and the like finishings for the purposes described, of a series of attachment means permanently secured thereto and consisting of short` prongs adapted to spread apart when driven home. By reason of their form and action when driven home these means can be made much shorter than the usual nails and yet provide a convenient and secure anchorage for the finishing or molding. In the accompanying drawing,

Figure 1 is explanatory of one of the difficulties which are at present experienced in attaching finishings and moldings of the kind herein referred to by means of ordinary nails.

Where, as represented in Figure 1, it is required to secure a beading or molding a. around a sharp 10 bend by means of ordinary nails b of the requisite length, it will at once be obvious that the operation is attended with considerable difficulty. Even where the beading is of a flexible nature it is by no means an easy thing to fix it at the 15 corner so that it lies uniformly and is at the same time secure. The difilculty is considerably greater when the molding is made of a ductile metal, for if the nail b is bent so as to be presented at right angles to the surface c the result is to cause the molding to form a, hump at the corner, whereas if an attempt is made to drive the same nail b obliquely into the surface c it either lies flat and does not enter at all or it takes a very insecure hold, with the result that there is always a tend- 25 ency for the molding to gape at the corner.

These difiiculties are entirely avoided and a firm and durable attachment readily made by the adoption of attachment devices of the kind hereinafter described which are permanently se- 30 cured to the molding or beading.

In the form shown in Figures 2 and 3 the improved attachment devices consist of lshort T- shape driven means formed with short bifurcated Shanks and having a spread head, and xed at 35 intervals to a metal stripv e embedded in the beading a. Owing to the increased security which is afforded by the spreading and clinching of their furcations the Shanks of these fastening devices or means need not extend more than la quarter 40 of an inch from or beyond the face of the beading in which they are embedded and consequently the attachment of the beading thereby is rendered a comparatively simple matter whatever may be the contour of the surface to which it is to be applied. These bifurcated fastening means kcan either be made separately and welded, or otherwise secured to the strip e, or, they may be made as integral parts of the metal strip z' by forming them opposite each other along the edges of 5o the strip, bending them at right angles to the latter and then twisting them about each other as lshown in Fig. 'I so as to form a bifurcated shank having furcations f that will spread apart below the twist when driven home. 55

60 therewith y Where the fastening means are formed `inl According to the preferred embodiment the individual fastening or securing means is made Aof a piece of preferably flat thin stiff metal wire folded upon itself into T form, the head constituting a flattened loop with the two end portions depending in close proximity from the central portion ofthe head to form a bifurcated shank havingprongs or furcations ,f which are preferably of substantially equal length and have their adjacent lower'end edges beveled downwardly and outwardly away from each other as at f', Aas shown in Figures 2 and 4, so that when driven into a support or foundation the material of the latter will initially enter between said beveled faces as a wedge and force them to spread, such action progressively increasing as the fastener is driven home, with the result that each furcation or prong f is arcuately bent away from the other prong or furcation f and to some extent back upon itself, thus firmly anchoring in the material of the. support or foundation. The furcations f being of stiff unhardened or untempered thin wire stock with thefurcations extending substantially parallel closely adjacent 4each other and with their distant outer edge faces extending vertically and being intersected by the beveled faces f' to form cutting penetrating edges, it follows that on being driven into the support or foundation the furcations will penetrate the same closely adjacent each other, and will only begin to bend apart within the body of the foundationor support itself, the furcations ,f not being spread or pried apart, but held close together by the material of said support adjacent said furcations. Consequently, these fastening means, although less than half the length of ordinary nails, will provide a firm and lasting attachment for the molding or the like and by reason of their short length the uniform attachment of the molding around sharp bends is rendered a comparatively easy operation. Where, as shown in Figure 6, the material g to which the attachment is made isof a shallow depth, for instance a wood veneer, and mounted cna metal plate or foundation h the improved attachment devices not only spread when l driven home but the ends on meeting the metal plate are deflected to produce an effective clinch.

In the case of metal moldings, suchv as the drip may, as shown, Abe'formed with a longitudinal channel a1 and the heads j? of the attachment devicespermanently secured therein by rolling over the lips'v a2 of thev channel. Or, again, the

' said devices may bejweldedor soldered tothe molding or-the latter'maybe perforated to re` f ceive the. attachment-deviceswith'a driven'o'r forcent so as `to/beconle permanently associated I tegrally'withfthe metal stripi'byfbeing. formed with lopposed downwardly and outwardly beveled Q ismadefof foldedfabric, `as shown in Figures- 9.

f faces f as above-described for the reason above stated.

11n some cases where the core ofthe beading and-ljthe attachment'devices fgare first driven through the unfinished core a3 at intervals -along .its length and the heads spot welded to a strip of 'metal e1 running lengthwise of the core.

The formation of the core is then completed so as to enclose this strip e1 and covered with an outer covering lc of fabric or the like.

Alternatively, as represented in Figures 11 and 12 the attachment devices are driven at intervals vthrough the uncompleted core a3 in the form of staples f3 the projecting limbs or prongs of which are subsequently pressed together `parallel with each other to form a bifurcated shank, the loop at the closed end engaging'the material of the core and providing a very secure anchorage. As before, the core'is then completed and enclosed in an outer covering k. The free ends ofthe prongs are bevelled as shown so that when the spike is driven home they will spread apart, and securely retain the beading in position.

Besides the facility with which headings and the like can be attached when using attachment devices of the kind herein described the latter, as already intimated, with reference to Figure 6, have the further advantage that owing to their short length but elfective form they can be used where the material tol which the attachment is to be made is of shallow depth and for which ordinary nails would be entirely unsuitable.

I claim:-

Beading comprising a body portion and a plurality of short attaching means to be driven into a support to which the beading is to be attached, said attaching means being permanently connected with said body portion and extending at right angles from one face thereof at spaced intervals lengthwise thereof, said attaching means having bifurcated support penetrating shanks and having their lower adjacent edges of their respective furcations beveled downwardly and outwardly away from each other, so that on being driven into said support said furcations will be progressively. forciblyrspread to positively interlock with the material of said support to resist pull in the reverse direction, whereby fastening means with shanks much shorter than the conventional nails heretofore used may be employed. 2. Beading comprising a flexible body portion f and apluralityofgshort attaching, means to.be Y driven into a support to 'which the beading is to be attached, said attaching means being permanently connected with said body portion and extending at right angles from one face thereof,
