JERSEY.

WOODEN PANEL.

Laatse-o.

Application led. August 20, 1920.

To @ZZ whom it may concern Be it known that we, EDWARD K. KEPLEY, a citizen ot the United States, residing at Boonton, in the county of Morris and State of New Jersey, and CHARLES A. COLE, a citizen et the United States, and resident ot Jersey City, in the county ot Hudson and State ot New Jersey, have invented certain new and useful Improvements in Wooden Panels, of which the following is a full, clear, and exact specification.

rl`his invention relates to wooden panels for use in doors, walls, etc., and has tor its object to produce a panel which will not warp and buckle out of shape under chang.

ing temperatures and varying weather conditions.

Another object is to simplify the construction ot such panels and produce the same at small expense. Other objects will appear as the description proceeds.

The invention will be first hereinafter describedin connection with the accompanying drawings, which constitute-part of this specication, and then more specifically defined in the claims at the end of the description.

In the accompanying drawings, wherein similar reference characters are used to designate corresponding parts throughout the several views Figure l is an elevation ot a panel made substantially in accordance with this in# v vention.

Fig. 2 is a similar view with the front board removed.

Fig. 3 is a section on line III-III of Fig. l.

Fig. 4 is a view like Fig. l but indicating a modified form oi" spacing strips in dotted lines, and

Fig. 5 is a section on line V-V of Fig. 4 drawn to a larger scale.

In Figs. l. 2 and 3, the front and rear boards l and 2 of the panel are spaced apart by strips 3 and 4. the strips 3 extending the full length ot the boards and the strips 4 extending along the ends thereot' between the end portions ot said strips 3 but terminating short of and out ot contact with said strips 3. Spaces 40 are thus lett between the lateral spacing strips 3 and the end spacing strips 4 which allows for such expansion .and contraction as may be caused Specification of Letters Patent.

by changes in temperature and weather conditions, and prevents the panel from warpsuitable means to the tront and rear boards v l and 2 separately but said strips are not otherwise fastened to one another, so that each strip is kfree to contract and expand alone without affecting the others.

As illustrated in Figs. 4 and 5, the chances of warping and buckling of the panel may be further reduced by making the spacing strips in a plurality ot sections with overlapping slip joints, so that each section of each strip may contract and expand independently without affecting the other sections ot the same or other strips. 'In this modification the front and rear boards of the panel are designated 5 and 6, the lateral spacing strips 7 and the end spacing strips 8. As best shown in Fig. 5, each of said end spacing strips is made in two sections having overlapping slip joints or rabbeted portions 9 which do not abut at the ends but leave spaces 10 to allow for expansion of each section independently of the other.

Each of the lateral spacing strips 7 is similarly formed ot two sectionshaving'rab-V beted overlapping end portions indicated at 12 in dotted lines in Fig. .4, said overlapping portions 12 being similar to those 'illustrated in solid lines at 9 in Fig. 5. Said For instance, the longer lateral by Letters Patent oi the United States is 1. A panel consisting of Jfront and rear boards and wooden spacing strips secured to both boards along each longitudinal and transverse edge of the panel but otherwise Aunconnected to each other, lthere being spaces between the end portions of said strips for the purposes specified. v

2.- .A panel wnsstng .ot ,front and rear boards and Wooden spacing strips secured to both boards but otherwise unconnected to each other, there being lateral spacing strips extending the entire length of the boards and end spacing strips extending along the ends of the boards and terminating short of the end portions of said lateral strips for the purposes specified.

3. A panel consisting of front and rear boards and Wooden spacing strips secured to both boards along each longitudinal and transverse edge of the panel but otherwise unconnected to each other, each strip being composed of a plurality of separate sections, said strips and sections of the same strips being spaced apart at their ends for the purposes speciied. Y

4. A panel consisting of front and rear boards and Wooden spacing strips secured to both boards along each longitudinal and i transverse edge of the panel but otherwise unconnected to each other, each strip being composed of a plurality of separate sections having overlapping slip joints with their ends spaced apart for the purposes specied.

5. A panel consisting of front and rear boards and Wooden spacing strips secured to both boards along each longitudinal and transverse edge of the panel but otherwise unconnected to each other, one or more of said strips being composed of a pluralityV oit separate sections having overlapped end portions, the ends of the strips and the ends of the sections of the sectional strips being spaced apart for the purposes specified.

In testimony whereof We have signed our names to this specification.
