ATTORNEY UNITED STATES I ATENT Gaston,

LUDWVIG F. MERGOTT, OF NEWARK, NEW JERSEY.

JOINT FOR BOXES.

SPECIFICATION forming part of Letters Patent No. 372,694, dated November 8, 1887.

Application filed August 15, 1887. Serial No. 247,036. (No model.)

To all whom it may concern.-

Be it known that l, LUDWIG F. MERoo'rT, of the city of Newark, in the county of Essex and State of New Jersey, have invented certain- I new and useful Improved Joints for Boxes; and I do hereby declare that the following is a full, clear, and exact description of my invention, reference being had to the accompanying drawings and the letters of reference marked thereon, which form a part of this specification.

For a more perfect understanding of my invention and its objects, I will state that here tofore joints for boxes were made in such a manner that some portion of the cross-cut rough surface appeared, except when thejoint is made as shown in Figure 5; but joints made in that manner are ditlicult to construct, requiring some considerable care, a separate tenon, and a pressure from four sides while the glue is setting; and also except when the joint is made as detailed in Patent No. 171,326, granted to George S Stearns; but joints made in that manner are objectionable, because one side of the box must be twice the thickness, at least, of the corresponding end, or vice versa, in order to avoid the appearance of the cross-cut rough surface of the wood, and be cause,also,the dovetail tongue and groove are more ditficult to construct and put together and the glue is scraped off in uniting the cor- 11ers.

To avoid these several objections is the object of my invention.

In order to enable others skilled in the art to which my invention appertains to make and use the same, I will now proceed to describe the manner in which the same is or may be made, referring to the annexed drawings, in which-- Fig. 1 is the top view of the box, showing exactly how the different pieces are sawed or cut, and how they are united and joined one to the other. Fig. 2 shows the two sides as they are about to be united, forming thejoint lock or corner. Fig. 3 represents the corner of the box when joined, showing a complete smooth surface, the grain of the wood meeting, and no cross cut rough surface appearing. Fig. 4 is a view of two parts joined together. Fig. 5 is a view of the old form of joint referred to.

The shapes D, E, and F are made to match with exactness the opposite shapes, A, B, and C. The parts 0 E are female parts and the parts F B are male parts. D and A are miters. These shapes, as described, can be made smaller or larger to suit the thickness of the material used. The shapes A, B, O, D, E, and F can be made on an ordinary circular-saw table, either with circular saws shaped and adjusted in a suitable manner or with shap- -ing-knives.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

A new, useful, and improved joint for boxes, having the female part 0, the male part B, and the miter A, in combination with the other side having the male part F, the female part E, and the miter D.

In witness whereof I have hereunto set my hand in the presence of two subscribing witnesscs.

LUDWVIG F. MERGOTT.
