PANEL.

Specification of Letters Patent.

Patented Jan. 27, 1914.

Application filed November 23, 1912. Serial No. 733,204.

To all whom it may concern:

Be it known that I, Brno C. ROCKWELL, a citizen of the United States, residing at Camden, in the county of Ouachita and State of Arkansas, have invented a new and useful Panel, of which the following is a specification.

This invention relates to devices of that type known as raised panels such as com monly used in the construction of doors, partitions and the like.

In constructing a panel of two or three pieces it is, at the present time, the practice to make the pieces of greater thickness than the thickness of the finished article so that, after the pieces have been matched and glued, they can be finished down to the final thickness so as thus to render the glue lines inconspicuous. This operation has been necessary in view of the fact that matching cannot be done accurately enough to enable the panel to be finished with sand paper. l urthcrmore the glue will ooze from between the pieces and tend to gum the sand paper so as to make it practically impossible and, under any circumstance, quite expensive to finish a panel by following this method.

The present invention has for its object to so arrange the several pieces constituting the panel as to bring the glue lines in or at the angle portions of the panel where they cannot be noted. As a result the parts constituting the panel can be first dressed to the proper thickness after which they can be assembled as heretofore, the surplus glue 0ozing out onto adjacent parts of the panel which parts are subsequently removed in shaping the panel. As the glue lines are thus located along the angles of the panel, they will not be seen and, as it becomes unnecessary to redress the panel after the parts have been matched, it will be apparent that a panel made up of matched pieces can be more cheaply constructed than heretofore and a better product can be obtained.

A further object is to provide a raised panel made up of two thicknesses of lumber, the marginal portions being formed of thinner lumber than the central portion, thus making it possible to utilize accumulations of thin or narrow lumber.

Another object is to construct the edge portions of the panel out of thin lumber so that, by applying glue to the edges of the thin edge strips, the glue will not ooze onto the faces of the thick portion of the panel while the parts of the panel are being assembled.

lVith the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodin'lent of the in vention herein disclosed, can be made within the scope of what is claimed, without departing from the spirit of the invention.

In the accompanying drawings the preferred form of the invention has been shown.

In said drawings: Figure l is a front elevation of a panel constructed in accordance with the present improvements, the same being shown in position within a door or other structure, only a portion of which is illustrated. Fig. 2 is an enlarged transverse section through the panel in its finished condition. Fig. 3 is a view similar to Fig. 2 and showing the shape of the panel prior to be ing finished. Fig. 4c is a view similar to Fig. 2 but showing the arrangementv of the pieces in' constructing a panel in accordance with the practice heretofore followed.

Referring to the figures by characters of reference 1 designates the thick middle portion of the panel, said portion being formed in one piece and being dressed down to the thickness of the finished panel. This central strip 1 has grooves 2 formed in the longitudinal edges thereof, these grooves being adapted to receive beads 3 formed along the inner edges of the side strips 4 of the panel. The side strips are formed of thin and narrow strips of lumber such as accumulate in mills and these side strips at are of a thickness equal to the greatest thickness of the edge portion of the finished panel. In assembling the strips at with the central strips 1, glue is placed on the inner edges of said strips 4 and the strips brought together, as shown in Fig. 3. Any glue which may ooze from between the strips, will not flow onto the faces of the middle strip 1 but will, instead, flow, against the shoulders formed by the middle strip 1 and spread, if at all, back onto the faces of the edge strips 4. After the glue has dried the edges of the strip 1 are beveled, as shown at 5, or can be given any other suitable shape and the faces of the strips 4: are

dressed down to the desired contour thus to form reentrant angles at the lines of the glue joints. For example the finished panel can have the cross sectional contour illustrated in Fig. 2.

A comparison of Fig. 2 with Fig. 1 will show clearly the advantage in the present structure over that of the panels made in accordance with the practice heretofore followed. As shown in Fig. 1, the strips are all. of the same thickness and when brought together the glue will obviously spread out over the faces of the strips. As the strips cannot be finished with sand paper because the paper becomes gummed by the glue, it is obviously necessary to dress the panel down to its final thickness in order to remove the gummed surfaces of the panel and render the glue lines as near invisible as possible. In the present device, however, the glue lines extend along the angles formed between the strips 1 and 4: and cannot be seen. Furthermore it is not necessary to redress the panel but the strip 1 when first dressed, is given the thickness of the finished panel and the only dressing necessary is the shaping of the edges of the strip 1 and of the side strips 4:. Thus one of the operations heretofore necessary in producing panels of this character is eliminated.

WVhat is claimed is 1. A panel consisting of a central or raised portion formed in a single piece, and side strips formed of thinner material and glued to the side edges of the raised central portion, said panel being finished in two bevels to form rentrant angles at the lines of the glue joints.

2. The herein described method of building panels which consists in placing an adhesive upon one edge of each of two side strips, then attaching said edges against the sides of a thicker middle strip whereby the adhesive is caused to ooze from between the strips and to spread onto the faces of the thin strips, and finally finishing the panel in bevels on the middle strip strips respectively to form rentrant angles at the lines of the adhesive joints.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature in the presence of two witnesses.
