Patented Mar. 7, 1933 PATENT OFFICE ROBERT C. SCHEMMEL, OF AUNION CITY, INDIANA FINISHING WELT appuation mea'Juiy 8,'1929. serial No. 376,789.

My present invention relates "to improvements in welts, bindings, mouldings and finishing strips used in trimming automobile bodies and tops and `especially'in upholsterin the interiors thereof.

uch welts are commonly made of a base portion on which are superposed two or more longitudinal beads encased in a continuation of the fabric material which forms the base portion, for the purpose of concealing, when the welt is in linal applied position, the nails, tacks or other fastening means employed to secure the welt to the structure to be trimmed. Such welts are known as blind nail welts, A and since the issuance of United States Letters Patent No. 1,226,600 to me on May 15, 1917, have been made in a variety of shapes and types and of -many different materials.

It is frequently desirable to provide welts with bead coverings of contrasting colors to harmonize with an automobile interior done in two colors, or, when the welt is to be applied to the outside top of a vehicle, to produce a trimming in a plurality of colorsV and/or materials which will harmonize with the different colors of the body finish and upholstery.

In all the welt constructions of the prior art with which I am acquainted, the several A beads which are attachedto the welt base portion are necessarily encased or enveloped in a single continuous strip of covering material. When, therefore, ithas been desired to v i produce a welt having its several beads enclosed in fabric of dissimilar materials or of contrasting colors, it has been necessary to apply a paint or dye to the bead covering of the finished welt to simulate different ma- "'50 to be concealed from view when the welt is in its applied finished position on the supporting structure to be trimmed.

lVith lthese and other objects in view, my present invention consists, in certain forms y of embodiment selected by way of exelnpliication, in the novel welt structure illustrated in the annexed drawing, described herein and particularly pointed out in the appended claims. l

In the accompanying drawing which 69' forms part of this application for Letters Patent, and in which the same reference numerals indicate like parts in the several views,

Figure 1 is a perspective view, inwsection at one end, of one type of welt constructed 63 according to the principle of my present invention and y Y Figs. 2 and 3 are similar views of two other types of-welt illustrating further applica- A, tionsof the principle of my present inven- 70 tion. v

Referring to the drawing, the reference numeral 1 thereon designates the customary relatively large half round bead which coacts with one or more smaller beads 2, in the types of welt which I have chosen to illustrate an applicationV of my present invention, to concealthe `tacks or other fastening means used tosecure the welt in place on the supporting structure to be trimmed. 3 indicates a 8g fillerstrip having incorporated therein pliable metallic weft strands which is secured to the large bead and anchored in the base portion of the welt to provide apliable hinging member to hold the large bead down upon S' the-base portion after the fastening tacks have been driven home, as particularly describedand covered in my previously issued United States Letters Patent No. 1,719,729, dated July 2, 1929. By the term base por- 93 tion I referto the assembly of parallel, contacting fabrics disposed underneath ythe hinged bead and intended to immediately overlie the structure to be trimmed. vThe large bead 1 is encasedin a flexible 9 fabric covering 4 of any desired material and color, which, according to my present invention, terminates along any convenient lines in the base portion of the welt. In the drawing. 1.1m@ indicated the terminal edges of 10 the fabric covering 4 by the reference numeral 5. It will be noted that in the case of each of the different types of welt shown in the drawing, the covering 4, before terminating in the edges 5, is disposed in two parallel, spaced apart layers in the base of the Welt.

The smaller bead 2, whether occurring singly or doubly in the welts shown in the different figures, is encased in a covering fabric 6, which in the case of each welt is continued into two parallel, spaced apart layers in the base of the welt to terminate in the edges 7.

Unlike the bead coverings of the prior art, which are single unitary pieces for all the beads of a given welt, the covering 6 of a welt constructed according to the present invention, as will be noted by reference to the drawing, is a distinct and separate piece of fabric from that forming the covering 4. The several beads of a single welt being there fore encased in as many distinct and different pieces of fabric, it is obvious that in the production of a welt according to the present invention, the coverings 4 and G may be formed of different materials, or of the same material in dierent colors, to achieve the object of this invention in an entirely satisfactory and inexpensive manner. It will also be apparent that the hereinbefore described method of uniting the different fabrics in the base portion of the welt provides an effective concealment of the seam from view and a means of protection therefor against accidental loosening. It should be observed that the Various fabric components of the base portion are preferably cemented together, according to the common practice in welt making.

While I have shown and described my present invention in connection with a. limited number of different types of finishing welts, all of which embody the pliable wire wefted fabric forming the subject of my prior Patent No. 1,719,729, it is to be understood that the selection of these welts is only by way of illustration of my present invention. The present invention is applicable to many other and different types of welts, being capable of incorporation in any welt having a base portion and more than a single superposed bead. The appended claims are therefore to be construed broadly and without limitation to the specific types of welts herein shown and described.

Having thus described my present invention what I claim and desire to secure by Letters Patent is:

l. A blind nail finishing welt comprising a pair of spaced apart base fillers, a base fabric encasing said fillers and having a free edge therebetween positioned close to one of the fillers, a flap filler, a. separate strip of fabric encasing said flap filler and having its free margins extended from one edge of the flap filler, then folded back beneath the flap filler, terminating in interitted relation with the free edge of the base fabric, and a line of stitch ing passing through the base and flap fabrics adjacent the free edge of the base fabric to unite the base and flap securely together in hinged relation near said last mentioned base filler.

2, A blind nail welt including a flap bead and a base bead, a fabric encasing the flap bead and terminating beneath said bead in a pair of parallel plies, a separate fabric encasing the base bead having both of its margins terminating beneath said flap bead in parallel interfitted relation with the margins of said flap bead-enclosing fabric and cooperating therewith to form a base having at least four plies, and a line of stitching uniting said four plies near one edge of the fourply portion of the base and forming a hinge connection for the flap bead and base.

In testimony whereof I afliX my signature.

ROBERT C. SCHEMMEL.
