WALL-BOARD OINT-FILLER STRIP.

Application filed July 12,

This invention relates to a process and means for completing the juncture between wall hoard sections in forming a wall to avoid the appearance of unsightly. cracks or openings at the juncture between the wall boa rds.

lt is well known that. wooden framework to which the wall boards are nailed will shrink and expand with weather conditions, inducing corresponding movement in the wall. board sections and thus producing the unsightly cracks or openings which the present invention aims to overcome. Attempts have been madeto avoid this objection by inserting wooden or like strips between wall boards but the correction is but temporary as the inserted strips do not partake of the same expansion and contraction as the wooden framework and eventually that separation occurs tending to produce the unsightly appearance referred to. p

The present invention aims to overcome these ditliculties by inserting a filling strip which is more or less ex pansihle and which is so formed as to provide for self-ventilation to compensate for differences in expansion and contraction.

The invention is illustrated in the accompanying drawings, in which:

Figure l is a view in elevation'showing adjacent wall boards and the use of the improved sealing strip.

Figure 2 is a section on line 2-2 of Figure 1. i

Figure 3 is a broken perspective View 0 the sealing strip.

The wall boards 1 are nailed or otherwise secured to the wooden framework 2 in proriding a wall structure, and for the purposes of the present invention the adjacent edges of the wall boards are spaced slightly apart to provide a channel 3.

A sealing or spacing strip 4 is inserted in the channel 3. such strip being of a thickness slightly exceeding that of. the channel and being itself channeled on the under side, as at 5, to leave comparatively narrow more or less resilient. leg portions 6. If desired,

the strip. is'slightly greater in width than the space, there is a frictional holding provided between the wall board and the edges of the strip, it being understood that the leg 6 will yield slightly to compensate for the difference in width.

The surplus cementing, material is then {wiped off the face and when the strip is finally seated'by the hardening of this materiah it Will be found that the ventilating space provided by the channel 5 in the strip is suflicient to subject the strip to substantially thesame expansion and contraction as that of the wooden framework 2. Therefore, as the strip yields with the wooden framework, it naturally maintains a tight. juncture between the adjacent edges of the wall board and the usual unsightly cracks appearing under wall board application as heretofore. provided are entirely avoided.

It is, of course, to be understood that the con'ibined sealing and spacing strip may be constructed of wood. cork or other desirable and appropriate material.

\Vhat I claim to be new is:

1. The process of securing wall board sections to a framework, consisting of securing the sections to the framework with their edges spaced apart from each other, depositing of shellac or the like within the space and the insertion of a strip into the space, having a ventilating channel througln out. its length.

2. A sealing strip for the junctin'e. of wall boards, comprising a section adapted to be forced between the adjacent edges of the boards, said section being longitudinally
