'To all whom 'it 'may concern:

Be it known that I, ARTHUR N. Vvns, a citizen of the United States, residing at Youngsville, in the county ot'lVari-en and State of Pennsylvania, have invented a new und useful Furniture-Joint for W'ooden Structures, of which the following is a specification.

This invention has relation to joints tor wooden structures such as furniture and the like and it consists in the novel construction und arrangement of its parts as hereinafter shown and described.

rlhe object ot' the invention isto provide a simple and eiiectivemeans for joining together apposed pieces of wood ot a structure in such manner that they Will be iirmly held together without danger of splitting.

T he means constituting the joint consists of a hollow tubular member having the inner surfaces of its ends chamfered, whereby, edges are formed at the outer surfaceof the said member. Annnlar mortises are cutin the upposed pieces of Wood and the end portions of the tubular member are inserted in and seated in the said mortises. The don'el .screw or pin passes longitudinally through the tubular member und engages the apposed pieces of wood. The said tubes may be truly cylindrical in contour or its periphery may be provided with spirally disposed corrugations which afford friction surface tor entering the grain o'f the Wood.

In the accompanying drawing z-Figure l is .a sectional View of apposed pieces of` Wood secured together by the oint, and illustrating a spoke or leg connected with the said ,pieces of Wood at the point of juncture.

Fig. 2- is a sectional view of apposed pieces,

of wood showing a modified` form of joint. Fig. 3 is a sectional View of apposed pieces of wood showing a modified form of the tubular member ot' the joint. Figs. 4, 5, 6 and 7 are detailed sectional views of other modified forms of the joint.

lThe means for connecting the apposed pieces of wood together consists ot' a tubular sleeve l which is inserted at its opposite end portions in the said pieces of wood. Circular mortises 2 having been previously cut in the Wood for the-reception of the said sleeve. The inner end portions of the sleeve are chamfered, as at 3, and terminate in edges' located at vthe outer surfaces of the said sleeve. .;'viheseedges are adapted to be driven into, and securely seated, in the inner end portions of the mortises 2.

As illustrated in Fig. l of the drawing, a doWel pin 4 passes centrally and longitudinally through the sleeve 2 and is embedded at its end portion in the apposed pieces of Wood which are joined together. rThe said dowel pin also passes through the tcnon of the spoke 5, or leg, as the case may be, the said tenon passing laterally through the side of the sleeve 2 and being housed within the same.

In the form ot the invention as illustrated in Fig. 2, a double-pointed screw G is used as a dowel and is provided at an intermediate portion with a surface 7 upon which a Wrench may be operated.

In the form ot the invention as illustrated in Fig. 3, the exterior of the sleeve 1 is provided With a volute corrugation Which is adapted to become embedded in the grain ofV the Wood and more firmly secure the parts together. In the form of the invention a doivel pin et is illustrated although a dowel screw may be employed if desired.

In the form or" the invention, as shown in Fig. ft, the sleeve 3 is used tor the purpose of securing a tenon 8 to the piece 9. The screw 10 being passed through the tenon 8, the sleeve 3 and forced into the piece 9. The tenon 8 is then inserted in a mortise provided in the piece 10.

In the form of the invention as shown in Fig. 5, the sleeve l is illustrated as securing tvvo pieces ot ivood together' at a right angle to each other and a screw 1l is passed through one of the pieces and the sleeve into the other piece.

In the form of the invention as shown in Fig. (3, the sleeve 1 is embedded in the piece 12 which. is attached to the pieces 13 and 14 at the point where they are drawn together. The screw 15 (indicated Yby dotted lines) passes through the slcevel andv is embedded `in the piece l2 and is located at the joint between the pieces 13 and 14 While the dovvel screw G holds the pieces 13 and 14 together'. The intermediate roughened portion 7 thereof may be used for affording surface for glue to adhere to the screw. i

In the Jform of the invention as shown in Fig. 7, the dowel pin e, passes through the tenen-16 which is located in the sleeve l and which in Aturn holds together the Wooden I -Having described my invention what I claim as new and desire to -secure by Letters- I Patent is A joint for wooden structure eomprisin uplposed pieces having mortses, n cylindrica sleeve fittin snugly alon the entire length of the wa ls of the mortlses and having internal beveled ends which are forced into the material of the pieces at the ends of the moitises, and a dowel member passing I centrally and longitudinally through the l sleeve and being embedded in the apposed l ture. Y

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

ARTHUR NQ WEBB.
