' LIS-T OR FILLET FOR CREVICES Filed Oct. 29, 1931 2' J J 5 J 5 Fatentecl July 11, 1933 UNITE STATES ADOLF INGVALD LUND, OF OSLO, NORWAY LIST 0R FILLET FOR CREVICES Application filed October 29, 1931, Serial No.

My invention relates to a list or fillet,

adapted to be used in the joints between plates which cover walls, ceilings andthe like, and it is the object of the invention to provide a list or fillet which is cheap to manufacture, easy to use and which will cover the joint completely but at the same time allow the plates to move a little relatively to each other.

A suitable material for the new list or fillet is according to the invention a fibrous material, e. g. paper, cardboard, pasteboard, millboard and the like, which although it may easily be given the desired shape will be stiff and resilient enough for the present purpose.

The fillets may be manufactured haltready for use in the form of sheets or webs, from which the single fillets may be severed and bent to final shape. I

The invention is illustrated, by way of example, on the accompanying drawing where- Figs. 1, 2 and 3 disclose ditlerent embodiments of the new list or fillet;

Fig. 4: illustrates in cross section the list in Fig. 1 placed between two wall cover plates.

Fig. 5 is a similar view of the list shown in Fig. 2 and Fig. 6 illustrates how the lists may be manufactured in plates or webs from which the lists are later severed and bent to the final desired shape.

In Fig. 1 the list is shown in the shape of a massive rail having a head portion 1 and a leg portion 2, the latterbeing at its free end provided with flanges 3 extending laterally. The head portion is preferably somewhat oval in cross section, as shown. Fig. i illustrates how such a list may be placed between two plates l, 1. The

flanges

3, 3 then will rest against the rear side of the plates, and the head portion 1 entirely'covers the joint between the plates, so that no crevice is seen from the outer side. The length of the portion 2 is of course chosen so as to correspond to the thickness of the plates 4. The head portions 1 will also, to a greater or lesser degree, mark the borders of the adjoining plates and thus better indicate the pattern formed by the plates.

In Figs. 2 and 3 are illustrated lists or fillets prepared from sheet or web material. The head portion 1 is formed circular or oblong in cross section as shown or, may

also be of angular or other shape, and from the head extend two middle portions 2 each S011 should move somewhat away from each other the portions 2 will move also, due to the resiliency of the list,and no crevice will occur. This also makes the construction safer in case of fire, as no air draft occurs through the oint.

In order to make the manufacture, transportation and adaption of the lists cheap they may be manufactured in the form of sheets or webs and eventually rolled into reels from which the desired lengths may be severed, and then bent to final shape as they are placed in position.

Fig. 6 illustrates a portion of such a sheet. By passing the blank between suitable rollers or the like the head portion 1 is formed and at the same time weakening lines 5 are made, along which the flanges 3 are bent later on. If two or more lists are pressed side by side in a blank, weakening grooves or perforations 6 are provided, along which the several lists may be severed, e. g. by means of a pair of scissors. Then the severed list is bent to a shape somewhat as illustrated in Fig. 2.

It may be of advantage to insert in the head portion a thread, cord or the like, to make it more resistant against deformation and at the same time increase the springy action outwardly of the portions 2.

I claim:

As an article of manufacture, a fillet for joints of adjoining wall-plates, made of resilient fibrous material and comprising an enlarged head portion, and a leg portion disposed substantially at right angles to said head portion and having weakening lines permitting flanges to be formed extending in opposite directions at substantially right angles form said leg portion.
