(01. 155-491) ' This invention relates to chairs and more par ticularly to chairs used on lawns, piazzas and 'lik places, usually made of wood; ' One object of my invention is to provide a chair the main supporting parts of ‘which are so interlocked ‘with each other as to result in a rigid construction that will not permit any side or forward or backward weaving of saidparts which is so common in wooden lawn chairs. A 10 further object is to so form the parts of said chair that they may be cut from lumber by quantity production machinery with such uni formity and interchangeability that they may be assembled and completed by relatively, un 15 skilled labor, with the result that a chair is pro vided that is comparable in strength and rigidity with high priced chairs and whose production cost is substantially that of the lower priced chairs. 20 ‘ liia and the secondi‘one in from the front of my chair beingltb. Said slats are mainly support ed by said cross bars M. A back I1 is also pro¢ vided which is preferably made of a plurality of * slats as shown. Arms lS'eXtend from eachisaid 5 front leg to and beyond each rear leg, and are fastened to said legs by pin means as at l9, which arms support a transverse'brace 2! extending be tween them'at the rear of said back ll. Below , said transverse brace 2! are reinforcing mem- 1'0 bers 22 which’ extend diagonally across from one said leg to another. At the front of said front legs i2 is- a reinforcing piece 23 which is fastened to said legs ‘I 2 and extends from one to the other and is substantially ?ush with their outer sur- 15 faces. '- ' i ' i In order to strengthen my chair and to pre vent any weaving or loose movement of the parts bearing the greatest strain, each of said legs The foregoing and other objects'which will 7 l2 and E3 is provided with a recess 25 cut or appear as the nature of the invention is better otherwise formed in‘the inner side surface in understood, may be accomplished by a construc termediate' the top. and bottom edges of said ‘ tion, combination ‘and arrangement of parts such legs, which recesses 25 extend diagonally down ward from front to back, and in which end por as is disclosed .bythe drawing and speci?cation. 25 The nature of the invention is such as to‘ render ' tions of said cross bars M‘?t, as shown in the it susceptible to various changes and modi?ca tions, and, therefore, I am not to be limited to said disclosure; but am entitled to all such, changes therefrom as fall within the scope of my claims. In the drawing: Figure l is a perspective view of my chair. Figure 2 is a view partly in section taken on the line 2—2 of Figure l with the front slat of 35 the seat and the front reinforcing piece omitted to more clearly illustrate details of construction. Figure 3 is a View partly in section taken on the line 3-3 of Figure 1. V Figure 4 is a sectional View taken on the line 40 li-|l of Figure 1. Figure 5 is a View partly in section showing a View similar to Figure 3 of a modi?ed con struction. As illustrated my chair, has two front legs 12,. 45 and two rear legs 53, each pair of said front and rear legs being preferably opposite or in aline ment with’ each other, and each said pair hav ing a cross bar it extending between the legs, '50 which bars M are leveled off as at lilo, at their front ends, the end portions of said cross bars iii preferably being bolted as at l5 to said front and rearlegs. A seat l5, commonly made of a plurality of slats, has a front portion shown in the form 55 of two separate slats the ?rst or front slat being drawing. Said recesses 25 are quite shallow and only that partof said cross bars is representing a small fraction of their thickness extend into said recesses. As will be seen the bottom sur faces of said cross bars l4 in said recesses 25 bear against the lower shoulders 26 which the cut-out o: 0 portions 25 provide in said legs, whereby said cross bars M are actually supported by portions of said legs 12 in the'form of said lower shoul de'rs 26, instead of depending upon bolts to hold said cross bars and legs together as heretofore. 66 5 This construction prevents any appreciable for ward or rearward movement of said front and rear legs 12 and E3, or anyvertical movement of said cross bars Ill, whereas in the common construction of such chairs the Crossbars rest ?ush against the inner surface of said legs, and said legs and cross bars may move somewhat relative to eachother even when the bolts l5 holding them together are tight. It is the loose- 45 ness, which develops while in use, between said legs and said cross bars which is the bane of this type of chair. While the said recess 25 in a said front leg I2 is in the upper portion thereof, and the recess 25 in a said rear leg is in the lower portion thereof as shown in the drawing, as a matter of fact the distance from said recess to the top edge of a said front leg is the same as the distance from said recess to the bottom edge of a said rear leg whereby a front leg is inter 55 2 2,102,173 changeable with a rear leg, in other words a leg a said front leg l2, in which construction the may be used as a front or as a rear leg, thus cross bars do not extend into said cut-out por simplifying production as Well as reducing the number of different parts which go to make up tion 30. Also the ends of said seat front slat I6a extend in front of each said front leg l2 and are substantially flush with the outer side surfaces of said legs l2. This is made possible by lengthening said slat and in this longer por tion l?aa a cut-out portion 3| is provided at the extreme ends thereof, the front and inner sur faces of said front legs bearing against said cut-out, portion 3! as shown in said Figure 5. my chair. To further strengthen my chair the second slat in from the front of the chair l6b, which constitutes part of the front portion of said seat l6, has a cut-out portion 28 at each 10 end, said cut-out 28 extending from the front edge of said slat l6b rearwardly a short distance and forming a right angle as illustrated in Fig ure 3 of the drawing. This enables one to ?t the slat IBb against the front legs whereby the 15 cut-out end portion 28 extends within and bears against the inner side surface of each said front leg l2 while the remaining portion of said out out 28 continues at right angles and bears against the back end surfaces of said front legs l2, as 20 illustrated at 29 in Figures 3 and 5 of the draw ing, thereby further reinforcing and making more rigid said front legs l2 by means of said seat portion IBb‘. Chairs have a tendency to weave or rock espe cially at their front portion and in order to in crease the rigidity of the front portion and espe cially the front legs I2, I preferably cut out at each end of said front reinforcing piece 23 a portion of the inner surface as illustrated in Fig 30 ure 3 of the drawing, said cut-out portion be ing represented by the numeral 30. It extends inwardly from the extreme ends of said front reinforcing piece 23 only far enough to permit said front legs l2 and the front ends of said 35 cross bars I4, to enter said front reinforcing piece 23, the inner side surfaces of said cross bars [4 bearing against the shoulder 32 formed at the inner termination of said cut-out portion 30 as shown in Figure 3 of the drawing. 40 In the modi?cation shown in Figure 5 of the 25 - drawing the cut-out portion 30 is only large enough to accommodate and permit the entry of What I claim is: l. A chair comprising two front legs and two rear legs with bars extending between the front and rear legs and to the front edges of the 15 front legs, said bars being secured to said legs, and a reinforcing piece extending between said front legs and having rebated extremities into each of which a front leg and the extremity of 20 one of said bars secured thereto, is ?tted. 2. A chair comprising two front legs and two rear legs with bars extending between the front and rear legs and to the front edges of the front legs, said bars being secured to said legs, and a reinforcing piece extending between said front 25 legs and having rebated extremities into each of which a front leg and the extremity of one of said bars secured thereto, is ?tted, said bars ex tending diagonally downward from the respec tive front legs, to the rear legs. 3. A chair comprising two front legs and two rear legs with bars extending between the front and rear legs and to the front edges of the front legs, and a reinforcing piece extending between said front legs and having rebated ex 35 tremities into each of which a front leg and the extremity of one said bars secured thereto, is ?tted, said bars extending diagonally downward from the respective front legs to the rear legs and ?tted in diagonal recesses formed in the inner sides of said front and rear legs.
