IMPROVEMENT iN PARQUETRV.

Specification forming part of Letters Patent No. ELISWSQ, dated March 17, 1874; application filed January 29, 1874.

To all whom it may concern Be it known that we, FREDRICK Nnw- HoUsE and Moerman H. ALLEN, of Toledo,

Our invention relates'to improvements in' parquetry and similar ornamental wood-work; and it consists in the peculiar construction of the grooves or channels formed in the body or base to receive the strips to be inserted or inlaid to form the pattern, and also of strips to be so inlaid or inserted.

According to the ordinary mode of constructing parquetry and similar ornamental wood-work, either dovetailed grooves or channels are cut in the base across the grain of the wood, into which corresponding]y-formed dovetailed strips are forced or driven; or dovetailed channels are cut in the base or body, into which one-half of a double dovetailed strip is forced or inserted, leaving dovetailed channels above the base or body, into which dovetailed strips or sections are forced or driven.

In each of these arrangements, the direction of the fiber of the wood in the base or body, or the double dovetailed strips, is the reverse of the direction ofthe flber of the dovetailed strips inserted in the channels or grooves so formed or left, and, as a consequence, the wear ofthe diiferent portions of the surface formed by the combination of the different portions is unequal; and, further, by reason of the inclination of the sides, portions are liable to be split oif by reason ofthe inserted pieces or strips becoming enlarged as the surface is worn away.

To obviate these difficulties, we form inverted T-shaped grooves or channels, into which we insert correspondingly-formed portions of wood, by preference cut into strips or sections, with the grain running crosswise ot' the length of the strips or sections, so that when inserted into the grooves or channels the fibers of the whole combined surface shall run" in the same direction.

In the accompanying drawing, Figure l represents a plan, and Fig. 2 an edge ew, of a portion of ooring constructed according to our invention. Fig. 3 is a section of the same through the line ac a; of Fig. l.

A A represent a series of boards, forming the base or body ofthe flooring 5 and B B are inverted T-shaped grooves or channels formed in the same, into which are inserted correspondingly-formed strips O C, which are, by preference, cut into sections, with the fiber running crosswise of the length of such strips, and, as a consequence, the fiber of the com bined surface of the floor is all in one direction-. e., the direction of the length of the boards A A-a result which cannot be obtained by employing dovetailed grooves and llingpieces, by reason of the angular formation of the filling-pieces being rendered too weak and liable to split away, whereas, by the employment of inverted T-shaped grooves or channe s B and filling-pieces O, the sides of the channels are all vertical, and consequently not liable to be chipped or broken oft' from any cause; while the retaining portion c, being formed ot' one continuous piece of equal thickness and strength, is not liable to be wedged and broken, and also presents greater strength than a ,dovetailed projection in which the diameter of the projection is gradually decreasing, and consequently becoming weaker, toward the ex tremity.

Fig. 4 represents a plan view, and Fig. 5 an edge view, of a base-board vprepared in accordance with our invention, from which to form a molding; and Fig. 6, a vertical section of a portion of a base-board, A, with strips B inserted, according to our invention, formed into a molding by being run through an ordinary moldin g-machine.

Great variety of moldings and other ornamental wood-work may be formed by cutting the base A into strips, and planing or molding the same.

Having thus described our invention, what We claim, and desire to secure byletters pat- In testimony that We claim the foregoing, ent, is- We have hereunto set our hands this 26th day The improvement in parquetry herein deof January, 1874. scribed, consisting` of the inverted T-shaped channels or grooves B, formed in the base A, and the inverted T-shaped strips C, when constructed and arranged substantially as and for the purpose set forth.
