DOVETAIL LOCKED VENEER. APPLICATION FILED OCT. 17. 1916.
1,212,073. Patented Jan. 9,1917.-
- I BY A TTORIVE Y8 WILLIAM F. KRUEGER, OF CHICAGO, ILLINOIS.
DOVETAIL-LOCKED VENEER.
Application filed October 17, 1916.
To all whom it may concern:
Be it known that I, WILLIAM F. KRUEGER, a citizen of the United States, and a resident of Chicago, in the county of Cook and State of Illinois, have invented a new and Improved Dovetail-Locked Veneer, of which the following is a full, clear, and exact description.
This invention relates to veneered articles, and has to deal more particularly with means for looking a sheet of veneer on the wooden body of the article.
The invention has for its general objects to provide improved means for fastening veneer to a wooden base or body in such a manner that dampness or water will have no separating effect on the veneer but rather induce an increased holding action.
A more specific object of the invention is the provision of novel interlocking means between a veneered facing sheet and the body to be veneered, the sheet of veneer being provided with dovetailed grooves, in each of which is a wedge-shaped tongue eX- tending centrally and longitudinally, and on the wooden body are split tongues which register with the grooves and are forced into the same, whereby the wedges in the grooves spread the tongues so that they interlock with the undercut walls of the grooves, whereby the two parts are effectively bound together under all conditions, and when the article is subjected to dampness or water, the swelling of the fiber of the split tongues causes a firmer binding action.
WVith such objects in view, and others which will appear as the description proceeds, the invention comprises various novel features of construction and arrangement of parts which will be set forth with particularity in the following description and claims appended hereto.
In the accompanying drawing which illustrates one embodiment of the invention and wherein similar characters of reference indicate corresponding parts in all the views,
Figure 1 is a vertical section through a portion of the finished article; Fig. 2 is a sectional view of a sheet of veneer prepared for attachment to a body or base piece; and Fig. 3 is a section of the body or base piece prepared for receiving the veneer.
Referring to the drawing, 1 designates the body or base to which is fastened a sheet of veneer 2. The body 1, which is of wood,

Serial No. 126,091.
cross-section, and in each groove is a longitudinal centrally disposed wedge or splitter 7 which is adapted to enter the slots 4: of the tongues 3 so as to spread the said tongues into dovetail form, whereby the original parallel sides 5 will be thrown into divergent relation and interlock with the undercut walls 8 of the grooves 6.
Before applying the veneer, the back surface and grooves are coated with glue, as is also the tongued surface of the base or body 1. Veneer is then placed on the body with the tongues 3 registering with the grooves 6, and a suitable force is exerted to compress the veneer and body together so that the tongues will interlock in the dovetail grooves. The flat surfaces 9 between the dovetail grooves will adhere to the fiat surfaces 10 between the tongues 3 in addition to the tongues being interlocked with and adhering to the walls of the grooves. Veneer applied in this manner has been allowed to soak in water for three months, and when taken out of the water it has been impossible to pull the veneer from the body, and upon drying out, the wood fibers of the veneer and body appear to be interlocked as firmly as in the original state.
From the foregoing description taken in connection with the accompanying drawing, the advantages of the construction and method of operation will be readily understood by those skilled in the art to which the invention appertains, and while I have described the principle of operation, together with the article which I now consider to be the best embodiment thereof, I desire to have it understood that the article shown is merely illustrative and that such changes may be made when desired as fall within the scope of the appended claims.
Having thus described my invention, I claim as new and desire to secure by Letters Patent:
1. The combination of a wooden body having a plurality of tongues each divided longitudinally, and a strip of wooden veneer having its back face provided with a plurality of dovetailed grooves into which allel, and each tongue being split longituditongnes extend, and a longitudinal wedge in nally, and a sheet of veneer having doveeach groove for spreading the tongues to tailed grooves to register with and receive interlock in the grooves. V the tongues and a wedge in each groove 5 2. The combination of a wooden body whereby the tongues are spread to interlock having a plurality of pa 'allel tongues with the side walls of the grooves.
formed with their side walls initially par- WILLIAM F. KRUEGER.
