' lApplication Ie'd December 1.8, 1912.- Serial No. 737,424.

To all -w/wmI it may conc-em Beit known that-we, JOHN T. Blumen and CHARLES O. BREEGE, citizens 'of the United States, residing at Portsmouth, in

county of Scioto and State of Ohio, haveinvented certain new and useful Improvements in RoundfTop Work, of which the following is a specification..

Our invention'relates to an improvement in round top`work, .and it is applicable particularlyto table -tops land the like, the ob ject being to construct round top workof superior quality and at a greatly reducedV semi-.circular edge of the core from one end of the curve or semi-circle to the other, in

connection withat least two superimposed layers of veneers, the grains of which veneers extend in different directions, thev vgrain ofthe inner veneer in the main crossing theV ain of the core and the bent rim, and' sai veneers Inade'to adhere to each other and to the core and bent rimso' that they combine to laterally support and secure the bent rimto the core, and whereby both theco're and ri'm are entirely covered on their upper and lower surfaces and no end Wood of either is exposed save the-free ends of the bent rim.

In the accompanying' drawings--Figure 1 is a view in perspective of a table top with vparts of the veneers broken away, Fig. 2 is a view of the round edge of the table top, Fig. is an enlarged fragmentary, sectional view across the Abent rim B into-the core'A, and throughy the veneers 4 andi; Fig. 4 is a view 'in transverse section showing our im` provement applied to a round veneered flush rim and plan ed top, and-Fig. 5 is a View to show the different layers of veneers and cauls preparatoryto applying the pressure in the method of securing the veneers to the cores.

A, represents the core` made of any suitable stock, usually in strips of inferior quality, having one straight edge 1 where the ends of the table come together or vagainst the removable leaves, and a curved or semi-circular edge 2 which constitutes'the end ,or outer edge of the table.

B. a" bent. rim, either solid or brult-up, i

whichis rabbeted or otherwise secured byglue or in anyfother approved manner to the curved or semi-circularedge ofthe core extending continuously in 4a single `rim from 4one end of the straight edge to the other.

This bent solid or .built-up rlm may have an outer facing of veneer or not, 'accordingly as desired.

In the -form ofround top work illustrated in Figs. 1,- 2,and 3, the upper and lower surfaces of the core and bent rim are planed'oif ush with each other, and two vlayers ofl veneers 4 and 5 are glued on both the upper and lower surfaces` These superimposed veneers are preferably placed so. that their grain cross each other, the inner veneers in the main crossing the grain of the core and the bent rim approximately at right angles, and the grain of the outer veneers extending approximately parallel with the grain of the core.4 There is a reason fo-rthis, namely that the inner veneers hold and bind the rim' to the core, affording a ysupport therefor at every point throughout its length on both the upper and lower surfaces, thus affording effect-ual reinforcement over the entire.'

upper and lower supercial area of the rim, and at the same time a complete closure which prevents the penetration of. moisture. In this way, we produce a iine, substantial piece of work with superior, graining and finish aroundthe curved outer edges as well as on the upper surface of the' top, while at the same time completely lcovering' up all end wood in the coreandrim with the exl ception of the extreme ends of thelatter, so that none of these parts are exposed to absorb'moisture to cause warping, swelling and shrinkage, which has been the objection heretofore where the rims in round top Work' have been made up of separate piecesor seetions. In the round veneered flush rim and planked top shown in Fig. 4, the saine condiof greater. width than thetop, and is shown in thedrawings inbuiltup form, it being jointed to the curved outer edge of the core as illustrated or any approvedv manner, the topveneers being secured `in the same manner as previously described and with the 'io tions prevail, except that thebent rim' B is same effect, and the lower veneers reduced l in area, of course, to correspond with the lower surface of the core, which is not covered by the rim.

While any approved method of construction may be employed, it is our purpose to proceed in somewhat the following manner :-In the outer edge of the core and tongue, a groove or other form of joint is preferably planed. The rim is similarly fashioned, and the core and rim are then glued and fitted together. After being thus joined, they are planed on either one or both surfaces accordingly as provided with the rim shownin Figs. l, 2, and 3 or Fig. 4, so that the surfaces of the core and rim are perfectly flush. Glue is then applied to the veneers and the latter are placed above and below. theycore. As many of these tops as practicable thus put `together are superimposed with interposed cauls, the cauls being thicker than the depending 'or projecting edges of the rims, as shown in Fig. 6. The stock thus formed is then placed in a press where pressure is applied of upward of 3,000 pounds to the square inch, such pressure being upon the veneers and cores only, and-only upon the rims where the veneers extend over the surface of the latter. In this condition they are left Vfor several hours until the` glue has thoroughly set and dried. After this, the outer edges of the top veneers are sawed and sandpapered down flush with the outer curved .surfaces of the rims. This,l as previously stated, is an approved manner of many possible methods of forming our improved round top and round veneered iiush rim and planked top. l

Having fully described our invention, whatwe claim as new and desire to secure by Letters Patent, is-

l. Round top work comprising a core having a curved outer edge, a bent rim extending from one end of this curved edge to the other, thereby entirely covering the end wood of the core, at least one surface of the core and rim flush with each other, and at least two superimposed veneers made adherent to 'each other and to the core and 'rim with the grains of the two veneers crossing each other, and the grain of the inner veneer in the mainA crossing the grain of the core and of the rim.

2. Round top work in which the rounded edge is faced with a rim composed of bent wood, no end grain of which is exposed on the outer curved surface, and at least two layers of veneers glued upon the surface of the core and rim whereby to completely cover said flushl surfaces and bind the rim to the core..

In testimony whereof we affix our signatures, in the presence of two witnesses.
