Ja. 11, 193s. R. L. HQHL SHEATHING Filed March 5, 1954 INVENTOR RUSSELL L. HOHL Patented Jan. .11, 1938 SHEATHING Russell L. Hohl, Shaker Heights, Ohio Application March 5, 1934, Serial No. 714,021

4 Claims.

This invention relates to wall construction in which sheathing is employed, and is particularly adapted, as will appear, to exterior sheathing applied in the form of panel members.

The invention contemplates a panel member unit of sheet metal having a high glossy finish as of vitreous enamel. An object of the invention is to provide that the reecting effect of such lustrous nish shall be diminished as to the,

observer, so that the glistening appearance' of the wall will be diminished. As will appear, this is accomplished by deformations in the exposed surface.

The invention also contemplates a manner of mounting the panel units generally similar to the arrangement disclosedin the copending application, Serial No. 655,224 filed February 4, 1933 jointly by Munro W. Copper, Jr., and me, andmy copending applications, Serial No. 673,190 filed May 27, 1933, and Serial No. '711,176 filed February 14, 1934. In these said applications is disclosed a system of parallel runners of channel form, between which sheathing panel members are mounted, by engagement of lips upon the panel members, projecting into the runner channels. The nature of interengagement of the mounting parts tends to subject the panel parts between the runners to slight bending and/or tensile stresses. A further object of the invention is to provide that the face parts of the panel members shall not be deformed by such stresses; and as will appear the invention utilizes for the purpose, the same deformations by which the glistening appearance is controlled, as already described above.

Said copendng applications and this invention as well, contemplate the employment of non-metallic heat and sound insulating backing means for the face parts of the panel units. A further object of this invention is to provide improved means for securing such backing, as will appear.

The exact nature of this invention together with further objects and advantages thereof will be apparent from the following description taken in connection with the accompanying drawing, in which Fig. 1 is a perspective view partly in section and. partly broken away and taken generally as from the outside, in elevation, showing the elements essential to an embodiment of the invention; and Fig. 2 is an enlarged detail in horizontal section at a vertical joint between panel units, as indicated by the line 2-2 in Fig. 1.

With reference now to the drawing, A, A represent generally a pair of sheathing panel units (Cl. 18S- 85) to be mounted beside each other upon the wall 2 inturned to enter the cavities l of the correi spending pair of runners B, to engage the near sides of the latter with resilient characteristics. Obviously by this arrangement a panel unit is mounted for support upon a pair of runner members by simply pushing the sheathing panel, suitably positioned. A backing 3 of non-metallic material having heat and sound insulating properties, is provided for the face part of each sheathing panel unit. The runner members B are provided with the shoulders indicated, in which the backing panels 3 are positioned, and by which a stop is provided for the inward mounting movement of the panel units.

As indicated the panel members themselves are of `sheet metal. They are preferably faced with vitreous enamel or the like, baked on, and providing a surface of extremely high luster-too high to be serviceable as an exterior finish. That the effect of this lustrous surface be diminished, the face parts of the panels are provided as indicated in Figs. 1 and 2, with deformations running between their lip parts 2. Such deformations may be of 4such depth to produce shadows, but at any rate they break up the plain reiecting surface that would otherwise result from the high luster finish. The appearance of the surface from any distance is thus softened and made more pleasing, with just enough luster remaining for the purpose. A

Such deformations produce another effect as well. Running vertically, they strengthen the face parts of the panel units between the runners B. Thus, regardless of stresses set up by the mounting forces upon the lips 2, the faces of the sheathing panels are maintained in the common general plane.

At each vertical joint between adjacent sheathing panel units, astretcher is provided, slidably to extend between the corresponding pair of runners B. Each stretcher is provided with a Cil tongue at each end extending into a groove on the runner members as at 4. Each stretcher is generally of channel form between its runners, as indicated particularly in Fig. 2, with a pair of side members 5 forming a channel cavity 6 therebetween. The side edges of the panel units are provided with lips l, the parts being so proportioned and arranged that the lips 'I enter their cavities 6 when panel units and stretchers are mounted on the runners. Preferably also the arrangement is such that the parts maintain their spaced relation as in Fig. 2. The stretchers are also provided with laterally extending flanges 8 adapted to provided shoulders for positioning the side edges of the panel backing means 3, along the vertical joints in a. manner generally similar to the described provision at the horizontal joints.

The manner of assembly will be apparent, assuming the runners B mounted upon the frame or body part of a wall. The stretchers are mounted between their runners and suitably adjusted therealong, and the sheathing panel units are then applied to the assembly simply by pressing them to engage their lips2 in the channels of the runners; the stretchers being of course suitably positioned along the runners that one underlies the vertical joint between each adjacent pair of sheathing panels between a common pair of runners. It will be appreciated that sheathing panel units will be applied to extend both above and below each runner although such additional panel units do not appear in Fig. 1. The backing members 3 are applied to the assembly each immediately before the application of its sheathing panel thereover, and the stretchers are conveniently positioned each against a backing member just laid and before application of the sheathing panel.

After completion of the described assembly, an exterior surface will be formed, of a plurality of panel unit faces in rectangular pattern, with channel cavities therebetween, provided along the horizontal joints by the runners B, and along the vertical joints by the stretchers. Plastic sealing cement is then applied to these channel cavities about each sheathing panel unit, as illustrated and described in the copending applications to which reference has been made. If preferred, the plastic cement may be added to the channels of the stretchers, before application of the panel units, so that the entire vertically extending cavity between units will be lled with such cement after completion of the assembly as indicated in Fig. 2.

What I claim is:

l. Building wall sheathing structure comprising a support member generally of channel form disposed with its channel cavity opening out- Wardly of the general plane of the wall, a metallic sheathing panel having a rectangular face part, with an inwardly turned lip part on one edge extending into and along said channel cavity, said support member having a laterally projecting longitudinally extending flange cooperative with the channel side part of said support member to provide a shoulder recess, and an insulating board backing for said panel face part having an edge part seating in said recess and there conned by said panel face part.

2. A building wall construction comprising a pair of parallel support members of generally channel form disposed with their channel cavities opening outwardly of the general plane of the wall, laterally projecting longitudinally extending flanges on said members cooperative with the channel side parts of said members to form shoulder recesses, a member disposed transversely of said support members and carried at the opposite end portions thereof by said ilanges, said last mentioned member being formed to provide a shoulder recess at the side thereof, a sheathing panel carrying a projecting lip extending into the channels of saidsupport members and cooperating with the walls thereof for holding said panel to said members, and an insulating board backing for said panel having edge portions seating in said shoulder recesses of all said members and there conned by sai-d panel.

Y 3. A building wall construction comprising a support member of generally channel form disposed with its channel cavity opening outwardly of the general plane of the Wall, a pair of sheathing panels each carrying a lip extending into the channel of said member out of contact with the walls thereof, said support member having laterally projecting longitudinally extending ilanges at opposite sides thereof cooperative with the channel side parts of the member to provide shoulder recesses, and insulating board backings for said panels having edge portions seating in the shoulder recesses of said member and there confined by said panels.

4. A building wall constructionl comprising a support member generally of channel form disposed with its channel cavity opening outwardly of the general plane of the wall, a sheathing panel carrying a lip extending into said channel cavity out of contact with the walls thereof, said support member having a laterally projecting longitudinally extending ilange cooperative with the channel side part of said support member to provide a shoulder recess, and an insulating board backing for said panel face part having an edge part seating in said recess and there conned by Said panel face part.
