CHAIR.

Application filed June 7,

I Our present invention relates to furniture and more particularly to chairs and it has for its object to provide a simple and efficient means for strengthening the frame of a chair in such manner as to counteract the and other unnatural positions and render the chair frame rigid without depending upon the seat for bracing purposes. To these and other ends the invention resides in certain improvements and combinations of parts all as will be hereinafter more fully described, the novel features being pointed out in the claim at the end of the specification.

' In the drawings:

Figure 1 is a side view of the chair constructed in one embodiment of our invention;

Figure 2 is a bottom view of the seat frame and seat taken in horizontal section through the legs on the line 2-2 of Figure 1;

Figure 3 is an enlarged fragmentary section through the front rail of the chair and a portion of the seat;

Figure I is an enlarged perspective view showing one corner of the chair frame;

Figure 5 is a fragmentary perspective of v the end of one of the rails of the seat frame and Figure 6 is a fragmentary perspective of the end of the reinforcing member.

Similar reference numerals throughout the several views indicate the same parts.

In general construction a chair made in accordance with our invention may be of the usual design embodying front legs 1 and back legs 2, the latter being continued upwardly to constitute the frame of the back 3. The chair is braced with rungs I and supported in the usual position on the legs is the seat frame embodying side rails 5, a front rail 6 and a rear rail 7 all of which have their ends suitably jointed to the legs. They may be tenoned or not and with the assistance of our invention a chair that is not tenoned is greatly strengthened. In the present instance we have shown angle brackets 8 at each joint between the rungs accordance with and illustrating 192s. Serial No. 643,880.

4 as well as the seat frame rails- We have also shown a solid seat 9,,resting on the seat frame and suitably secured thereto though it will, be understood that other seats may be employed. i

In the practice of our invention we protypes of vide the front ra1l-6 of the seat frame with a horizontally disposed reinforcing rail 10 rail with one edge disposed against the same. It is cut away at llrto fit the corner of the front leg 1 at each end and is provided with a tenon 12 at each end fitting a mortise or groove 13 in the side rail 5 to which it is preferably glued as well as to'thefront rail 6. In the latter case its connection is reinforced by a corner block 14 and just below the mortise13 an angle block 15 is pref erably used as a brace between the frame rails 5 and 6.

A chair reinforced in accordance with this invention will be found to hold its rigidity indefinitely being preferably solid at the front where tilting and other strains are apt to loosen the front legs in a chair of the usual design.

ing a corner of the leg projecting within the frame, of a reinforcing rail w1th1n and spanwhich may be of about the same proportion and .which lies directly in rear of the front i ning the frame below the plane of its upper edges to lie against the front rail throughout.

thelength thereof and having endsp-rovided with tenons cooperating with the inner side mortises in the side rails and further provided with recesses receiving and bracing the aforesaid corner portions ofthe legs and corner blocks bracing the front and side rails 5 in contact with the reinforcing rail and with j the leg.
