Feb. 4, 1930. F. w. MEI-IRRICK WELT Filed Dec. 4, 1925 Patented F b. 4, 1930 UNITED STATES PATENT OFFICE FRANK W. MERRICK, OF DORC HES'I'ER, MASSACHUSETTS, ASSIGNOR TO AMERICAN STAY COMPANY, OF EAST BOSTON, MASSACHUSETTS, A CORPORATION OF MASSACHUSETTS WELT Application filed December 4, 1925. Serial No. 73,255.

This invention aims to provide an improved finishing welt, particularly, though not exclusively, useful in finishing vehicle upholstery work.

In the drawings, which illustrate a preferred embodiment of my invention Figure 1 includes a plan view of a portion of an installation showing the use of tacks or nails (in dotted lines) for securing the 0 welt to the framework, and a plan view of a portion of an installation showing the use of staples (in dotted lines) for securing the welt in place;

Fig. 2 is a cross-section of the welt as it appears when being stitched;

Fig. 3 is a cross-section through the finished welt in position upon an upholstered framework before being secured thereto;

Fig. etis a section on the line 44 of Fig. 1;

Fig. 6 is a section showing the folds of the welt spread apart,,the tool for spreading the folds, a tack or nail ready to be forced through the welt to secure it to the framework and a portion of the tool for driving the tack into place; and p Fig. 7 includes a plan and a side elevation of a portion of the tool used in spreading the folds of the welt. so

a simple and inexpensive finishing welt of very fine appearance for covering the edges of upholstery and the like.

The upholstery installation selected for illustrative purposes, and shown in Figs. 1, 3, 4, 5 and 6, includes a wooden frame part 1, covered at one side by a metal covering 2, and at the other side by upholstery including padding 3 and fabric 4:. The edges of the fabric at and the metal covering 2 are extended over the upper edge of the frame part 1 where they are covered by the finishing welt 5.

The finishing welt 5, as shown, is preferably as illustrated formed from a single sheet of flexible material, such as waterproof cloth or the like, folded so as to provide a base portion 6 and a plurality of folds reinforced or filled by preferably hollow stiffening members 7 enclosed therein.

9 adjacent the base, material then extending in a and outwardly to provide upper folds l0 and I, able folding Fig. 5 is a section on the line 5-5 of Fig.1;

Referring to the drawings, I have shown v The material which provides the folds preferably extends, as illustrated, inwardly from both longitudinal edges of the base 6 to the center, thereby providing folds 8 and as shown in Fig. 3, thecurve upwardly 11 and the extreme edges of the naterial being wrapped over the edges of the base 6 and overlying the bottom face of the base 6 to form folds 12 and 13.

The welt is preferably formed by a suitand stitching machine (not shown) to which the materials of the Welt may be fed. The first operation (see Fig. 2) provides for forming the base 6 and folds 8 and 9, the remainder of the material being held above the center of the welt while the stiffening members 7 are fed into place upon the folds 8 and 9 and there sewn in place by suitable stitches 14 which extend through the base portions of. the members 7 through the folds 8 and 9 and through the base 6 of the welt, all as shown in Fig. 2. The stiffening members are then bent into the proper shape when the upstanding material is folded to form the folds 10 and 11. Before that portion of the material'which forms the folds 12 and 13 is folded under the base fi, an adhesive is applied thereto so that the folds 12 and-13 may adhere to the underside of the base When the welt is complete, the stitches are completely concealed by the folds as shown in Fig. 2.

The completed welt presents a relatively stiffened body portion upon which is disposed longitudinal folds which normal] touch or closely "approach eachother at the I In operation,

the body portion of by water or moisture.

enough so that the folds will return to their normal position after the tacking or other welt-securing operation.

To facilitate the tacking operation, I may provide suitable tools for spreading the folds and for driving the tacks while the folds are spread. These tool-s include a spreading tool 15 (Figs. 6 and 7) having a tapered and somewhat pointed nose 16, and a tack, nail or staple-receiving hole 17 located in the nose of the tool. The tacking tool 18 is shaped at one end to fit into the hole 17 as shown in Fig. 6. the nose of the spreading tool maybe advanced like a plow between the folds until a point is reached where a tack, nail or staple is to be inserted, then the tacking tool 18 is entered into the hole 17 (Fig; 6) and struck a blow to drive the fastening element 19 through the base of the welt and into the wooden frame part 1. As the nose 16 of the tool 15 moves along the welt, the folds open to permit tacking and then close in and conceal the fastening members, as shown in Fi 's. 1, 4; and 5.

The base of the welt may be arched (Fig. 3) so that when it is attached to the installation the welt will be flattened against the support, thereb exerting a downward pressure upon the edges of the welt to make them lie snugly against the'support as shown in Figs. 4 and 5. The arch effect is preferably obtained by arching the base portions of the stiffening members 7 before they are incorporated into the welt. Thus when the members 7 are sewn to the base 6, the base will also-assume the curvature of the bases of the members 7, as shown in Fig. 2.

Animportant feature of the invention is the fact that the waterproof material (which is usually only coated on one side) is folded so thatthat side of the material which is which can be reached The uncoated side of the material is not exposed to moisture at any coated is the only side side of the completed welt, nor in the groove between the opposed folds or flaps thereof. Thus I have provided a welt which will last longer than a welt having at least some of 'welts heretofore used'which, as

the uncoated side of the material locatedor exposed in such a manner that the moisture will act to decay and weaken the material.

By concealing the stitches, the welt is made more durable and is much neater in appearance than if the stitching were exposed, particularly at the upper face of the welt. The extended unbroken surface of the flaps or folds are of very-pleasing appearance, giving the impression of quality superior to various a matter of fact, are considerably more expensive to pro- 'duce.

While I have shown" and described a pre: ferred embodiment of my invention, it will be understood that considerable changes may be made without departing from the scope of my invention, which is best defined in the following claims.

1. A finishing welt comprising a base portion, folds extending toward the center of said base from the longitudinal edges thereof, outwardly extending folds continuing from the inner periphery of said first mentioned folds over the longitudinal edges of said base andterminating at the bottom face thereof, and securing means fastening sald first mentioned folds to said base, said securing means being concealed by said second mentioned folds.

2. A finishing welt comprising a strip of flexible material folded to provide a base portion and longitudinal inner and outer folds, said folds being disposed at the upper face of said base portlon at opposite sides thereof said folds being disposed at the upper face of said base portion at opposite sides thereof so as to provide spreadable portions normally tending resiliently to contact, said folds forming a continuation of said base portion with the outer edges of said inner folds adj acent the outer edges of said base portion and with the outer folds extending outwardly over the outer edges of thebase portion and secured to the under side thereof, and stiffening means enclosed by said folds for maintaining said spreadable port-ions in their normal position.
