My invention relates to finishing moldings of the type used'in trimming the exterior and interior of automobile bodies and the upholstery thereof, and this application is a continuation in part of my application Serial No. 560,437, led

August 31, 1931. More particularly the invention contemplates a finishing' molding provided with projecting fas tening elements.

An object of the invention is to provide amolding of the character indicated in which the projecting fastening elements are securely7 united to the core of the molding so that, upon penetration of the fastening elements into a support, the molding will be positively held in applied position.

Another object is the incorporation in a molding of a stiifening element adapted to maintain the molding around any desired radius of curvature without puckering or buckling.

A further object is the provision of a molding in which fastening elements are carried byv a continuous internal stiffening member, the latter being encased in a flexible core or body.` 'An important object of the invention is to provide novel means for assembling'the metallic fastening and stiiening elements andthe exible core or body.

A further object of the invention in one form of embodiment is to provide with the core a covering fabric secured thereto without the useV of 3'6 adhesives, so that, upon occasion, thecovering fabric may be temporarily disassociated'from the core to permit supplementary fastening Velements to be passed through the core, after which the covering fabric may be restored to its normal covering position.

A still further object of the invention in one form of embodiment is to provide a molding including a stiifening wire carrying fastening elements received in a channeled and slitted core,

fr the slit being so related to the channel that the Wire will most easily be admitted to the channel through the slit and yet be prevented, when received in the channel, from being separated therefrom through the slit when the molding is being 45' Y the invention in certain preferred forms of em.-

Referring now to the drawing, the molding which forms the subject of this invention includes l ailexible` core l, conveniently formed of molded or extruded rubber, woven or compressedvpaper, or anysuitable relatively flexible material usually employed for this purpose. The core carries a pliable metallic stiifening element preferably in the formof a soft annealed iron wire 2.V This 2'0 wire is conveniently disposed longitudinallyand continuously in the approximate center of the corel, being contained Vin a recess or groove of suitable form there provided. g The element 2, in addition to its stiiening func- V tion, serves to maintain securely in position a plurality of fastening elements 3, in the form of sharp pointed shanks spot-welded, soldered or otherwise permanently ysecured to and madeV Vintegralwith the wire-2 in uniformly spaced', align- 30 ment along one side thereof. The tacks commonly used Vwith moldings of this general v'type are thusdispensed with. f 1 The wire 2 Viscarried inthe core l'spaced up.- wardly from the bottom Asurfacel thereof, the fastening elements 3 being passed through the portion of the core between its recess which re'- ceives'the wire Zand the bottom surface of the core; YThe fasteningV elements VS'th'us project from Vthe bottom `surface of the core and, when 40 passed into a support, serve to` maintain theY core Asecurely mounted ,on the suppOrt. Figs; 2, 3, and 7 show three of several expedients contemplated by the invention by which the stiifening'wire 2is introduced into vthecore. 45 As illustrated in Fig. 2,L a kerf or slit 4 is cut from a side surface ofv the core 2 into the wirereceiving groove or recess atthe center of lthe core, and'in Fig. 3 a similar kerf 4c is shown eX- tending from the upper surface of the core. In Fig. 7 the slit-4b is made tangent yto the groove andthe wire and preferably breaks the surface of the corealong aline off-center'of the groove. 1t will be obvious that in each of vthevariant forms'of the invention the stiffening wire 2, with 554 its attached fastening elements 3, is incorporated in the core by merely expanding the sides of the kerf, introducing the assembly of elements 2 and 3 in such a manner that fastening elements 3 pass downwardly through the lower central portion of the core and the stiffening wire 2 seats snugly in the wire-receiving recess or groove. It is to be understood that the kerf or slit placing the interior groove or channel in communication with the outer suiface of the core may be extended from the groove to the core surface at any angle, three desirable angles being shown merely by way of exemplification in Figs. 2, 3, and 7, respectively. In this connection attention is invited to the form of the invention shown in Fig. '7 Where the tangential relation of the groove and the kerf results in disposing an overlying lip 'l over the wire 2 which assists in holding the wire snugly in the groove and prevents movement of the wire from the groove when the molding is being applied to a support.

Fig. 4 shows a further modification in which the wire-receiving groove consists in a trough or channel depressed from the upper surface of the core. In this form of the invention I prefer to provide the wire-receiving channel in a depth suiiicient to contain substantially all of the wire within the connes of the core, so that the covering fabric, hereinafter to be described,

when enveloped around the core, will not show.

any surface protuberance along the line of the stiifening wire.

In order to seal the surface of the kerf 4 or the surface depression shown in Fig. 4, and to finish the outer surface of the molding, I prefer to encase the core in a strip of covering fabric 5, conveniently of textile material. The covering fabric shown in Figs. 1-4 inclusive consists of a strip of any suitable textile material of cotton or the like, having any desired character of surface finish. Such a strip is secured to the core by an adhesive, the longitudinal edges of the strip being disposed in parallel relation along the bottom surface of the core close to and on opposite sides of the projecting fastening elements 3.

Figs. 5 and 6 show a modified form of covering fabric which is associated with the core without the use of an adhesive. This form of fabric includes warp and weft threads of cotton or the like, and a series of spaced transverse or weft threads of pliable metallic wire 6. I prefer to have the transverse wires 6 disposed in the interior or on the under side of the fabric, so as not to impair the ornamental character of the exterior surface finish thereof. The covering fabric of Figs. 5 and 6 is maintained around the core I by crimping the longitudinal margins over the bottom surfaces of the core. No adhesive is used, the stiffness of the transverse wire threads 6 being sufficient to maintain the wire fabric securely in its enveloped relation with the core.

It will be obvious that the wire cloth of Figs. 5 and 6 may be easily lifted and replaced. This capacity of the fabric is of value in many installations of molding, when it is necessary to supplement the regular fastening elements 3 with nails or tacks driven into portions of the core which are disposed around curves of short radius, or where it may be impossible to drive one of the fastening elements 3 into a support at precisely the point where the fastening element 3 is provided. In such a case, the wire cloth covering is temporarily lifted from the core, the supplementary tack or nail is driven through the core. and the covering fabric is then restored to its covering position, concealing the head of the supplementary nail or tack.

It is to be understood that the wire cloth type of covering fabric shown in Figs. 5 and 6 may be associated with the types of core shown in Figs. 3, 4 or 7, or with any other type of core contemplated by this invention.

It Will be appreciated that I have provided a molding having internal stifening means for maintaining the molding in any straight or curved 10 condition and in which fastening elements are permanently and securely united to the molding core. I have also provided a convenient and simple method of associating the fastening elements andthe core and of maintaining these elements 15 in their associated relation.

It is to be understood that I have shown the invention in certain preferred forms of embodiment merely by way of exemplication. The invention is capable of embodiment in other and 20 further modified forms, but all such modifications to the extent that they embody the principles of the invention as pointed out in the appended claims are to be deemed within the scope and purview thereof. 25
