JOHN WARREN AND JOHN W. ADDERLEY, OF DETROIT, MICHIGAN.

Specification forming part of Letters Patent No. 143,861, dated October 21, 1873 application filed March 8, 1873.

To all whom it may concern:

Be it known that we, JOHN' L. WARREN and JOHN W. ADDERLEY, of Detroit, inr the coimty of Wayne and State of Michigan, have invented a new and useful Improvement in the Manufacture of Oval and Curved Picture- Frames; and we do declare that the following is a true and accurate description thereof, reference being had to the accompanying drawings and to the letters of reference marked thereon7 and being a part of this specification, in which- Figure lis a perspective view of a part of an oval frame constructed after our improved manner. Fig. 2 is a crosssection of the same.

This invention relates to an improvement in the construction of curved, oval, or vcircular picture-frames of that class which are coated with composition as a finish for receiving` the color or gilding; and has for its object to reduce the amount of lumber required for their manufacture. The invention consists in making the narrow lprojecting fillet of the molding separately, of a thin hoop of tii'nber, bent and secured in a rabbet ofthe molding, in the manner more fully hereinafter set forth.

In the manufacture of turned oval frames of this class, pine or other soft lumber is used, and if not over one inch in thickness, cull lumber, costing from twelve to ifteen dollars per thousand feet, can be used for the purpose; but if the molding ,be over an inch thick-say, one and a half inch-lumber costing three times that price must be used, for the reason that no cull boards over `one inch thick are made in the manufacture of lumber. Aside from this economyT to be secured, there is another, in the actual amount of material to bev used in producing a frame of a given thickness.

In the drawing, A represents the molding of an oval picture-frame, having a projecting llet, A', which is a separate hoop of thin lumber, bent and sprung into a fillet, a, cut in woods the same relative economy in quantity 0f material used obtains.

VVh-at we .claim as our invention, and desire to secure by Letters Patent, is*- The combination of the molding A, having the rabbet a, with the fillet A', as and for the purpose described.
