The clamp members are adapted to receive the adjacent extremities of an adjacent pair of panel units 5, disposed generally in longitudinal planes to which the planes of the faces I and I0 are perpendicular, as illustrated Fig. 3.

Preferably, recesses are provided in the inner faces of the clamp members to receive and retain plastic sealing means, inwardly extending projections 4 and In' at the extremities of the clamp members being effective to provide the described cavities. Additional projections l" may be providedon the backing part clamplmembers to support the extremities of the panel units I against the plastic-sealing means 6 as the assembly is had, so that in the assembly the sealing means may be applied to the finishing part before the latter is applied to the backing part.

In practice the backing part is mounted upon the substructure of a wall or the like, conventionally indicated at 1, as by screws 0 located in holes drilled through the base portion ofthe backing part on the job. 'I'he panel umts 5 are next applied to the backing part, and the finishing part with its sealing means then applied to both backing part and panel units, the finishing part being pushed home until the panel units are clamped between the complementary parts.

The parts being of relatively soft material, they may easily cut to proper lengths on the job, as with a hacksaw. For economy, in some installations separate short lengths or sections of the backing part may be employed to mount a continuous single length of the finishing part by which the interruptions of the backing part are concealed.

With reference now to the modification of Fig. 4, the backing part is mounted upon a runner 10 instead of a flat structure such as indicated in Fig. 3. Such runner 10 and its purpose is fully set forth in my said copending application. It is sufncient here to state that the runner is generally of channel form `with re-entrant sides between which the base portion of the backing part extends, is positioned, and receives support, the backing part being assembled to the rimner by endwise sliding.

In the backing part here shown the clamp members are provided with longitudinally extending cavities having re-entrant sides terminating in rather sharp edges, the cavities receiving and the edges retaining yieldable sealing means 6l! such as hemp, felt or rubber beading. The beading extends beyond its cavities to have yieldable waterproof bearing upon the panel units which are mounted by application of the finishing part as before but without plastic sealing means.

It will be observed that the panel units 5B, Fig. 4, are much thinner than the panel units 5, Fig. 3, yet the finishing part is unchanged, as is the backing part with the exception of its sealing means. The channel member portions of the parts are identical as before, and obviously, either backing part is capable of mounting in either illustrated manner.

While the embodiments specifically illustrated and described have their clamp members extending at right angles to the interengaging faces of their tongue and channel members, for mounting of panel units disposed in a common general plane, it will be apparent that the clamp members could laterally extend at 45 degree angles to said faces, either rearwardly or forwardly, for mounting of panel units disposed in planes at right angles to each other, as at 6X ternal or internal corners between'wall panels. Similarly, accommodation for any angular relationship between adjacent panel units could be provided, the interengaging faces of the tongue and channel members being preferably disposed in planes generally angularly bisecting those of the adjacent panel units to be mounted. Or, the clamp members on one side of the parts could be omitted entirely, as for finish at a door way or the like. Likewise it will be apparent that the conformation of` the bose portion of the booking ,part may be otherwise than as specifically illustrated, to adapt the base part for mounting otherwise than in the typical manner shown.

Also, while as here shown the tongue member is upon the finishing part and the cooperative channel cavity in the backing part, this relationship could be reversed without altering the cooperative mounting eifectiveness between the parts.

Production of' the described complementary parts, both being preferably of relatively soft non-ferrous metal, is nicely had by extrusion. Aluminum, the metal which I found best suited for the purpose, lends itself admirably to production by extrusion. Such a production method permits any desired sectionalcontour with the uniformity and accuracy of dimension necessary for the spacing between the subsequently contacting faces, and also produces a flnish of pleasing luster for the parts.
