CHAIR CONSTRUCTION Filed Jan. '7, 1926 Patented Dec. 3, 1929 UNITED STATES PAT ENT OFFICE JOSEPH F. TAYLOR, OF GLEVELAND HEIGHTS, OHIO, ASSIGNOR TO THE TAYLOR CHAIR COMPANY, OF BEDFORID, OHIO, A CORPORATION OF OHIO CHAIR CONSTRUCTION Application fi1ed January 7, 1926. Serial No. 79,719.

This invention relates to chairs and similararticles of furniture, and has for its object to provide an improved joint construction, especially between the seat, seat frame,

; and back post, characterized by simplicity and strength, and giving an unusually rigid construction at the joint between the parts mentioned.

As commonly constructed, this joint is made by simply notching out the seat frame to fit against two sides of the back post, with a screw, perhaps, extending through the post and into the seat, the latter resting on the un* der frame attached to the post.

In the present construction, the defects incident to the structure referred to above are avoided, and a better joint is formed by notching both the back post and the seat frame, the post having an upper notch for the seat frame and a lower notch for the under frame, and these notches are disposed at angles to each other, so that the joint between the seat frame and the back post crosses the joint between the under frame and the back post, the parts being then fastened together by screws.

One form of this construction is shown in the accompanying drawings, in which Fig. 1 is a perspective view partly broken away showing the joint. Fig. 2 is a section on the line 22 of Fig. 1. Fig. 3 is a section on the line 3-3 of Fig. 1.

In the example shown, 6 indicates a back post or upright, and at the level of the seat frame the front face of this post has cut therein a notch 7 the base of which extends at an inclination so that a substantially triangular shoulder 8 is formed at the top. Directly be low and adjoining this notch is a lower notch 9, to receive the end of the under frame, and the plane of the base of this notch is at such an angle that it crosses the plane of the base of the notch 7, forming an upwardly pre sented shoulder 10 at the lower edge of the upper notch and a downwardly presented shoulder 11 at the upper edge of the lower notch, as well as a supporting shoulder 12 at the bottom of the lower notch.

The seat frame 13 is notched at the corner as indicated at 14: to fit within the notch 7 and so against the side of the post, being confined at the top by the shoulder 8 and at the botter, and is fastenedto the seat. frame by a screw 18 driven upwardly through the same and into theseat frame.

This forms a double notched joint or interlock which effectively holds the seat and its under frame in position, giving a. wide joint in the nature of a tenon instead of a flushor butt joint as has been used. The construction is capable ofconsiderable modification, or use in different relations, fromthat shown and described, and. no limitation in this respect is implied.

It will be noted that the

screws

15 and 17 are inserted through theside postsbelow and adjacent to the shoulders 8 and 10 respectively. Each of these screws has a round head indicated respectively at15 and 17, with a washer, 15 and17 respectively, interposed between the head of each screw and the bottom ofthe recess or countersink 19, 20 which receives such head. This construction enables the screws 15 and 17' to be drawn up more tightly than can be done with ordinary wood screws. Furthermore, the inner or threaded ends of the screws are dipped into hot glue, which insures permanent tight joints between the posts and the

parts

13 and 16. The recesses or countersinks 19 and 20 are deeper than the heads of the screws and the washers cooperating therewith thus enabling the use of'flush plugs in said recesses or countersinks to cover the screw heads.

Having thus described my invention, what I claim is: j

1. A jointfor chairs or the like comprising a posthaving upper and lower notches in one face thereof, the said upper and lower notches being cut on different angles, a seat frame fitting in the upper notch, and an under frame fitting in the lower notch and support ing the seat.

2. A joint for chairs or the like comprising a post having upper and lower adjacent notches in one face thereof cut on different angles to cross each ether, a seat frame fitting in the upper notch, and an under frame supporting the seat and fitting in the lower notch.

3. A joint for chairs or the like comprising a post having in one face thereof adjacent upper and lower notches extending crosswise thereof, the notches being cut at different angles so as to cross each other and forming upwardly and downwardly presented shoulders adjacent the crossing, a seat frame fitting in the upper notch and resting upon the upwardly presented shoulder, an under frame supporting the seat and fitting in the lower notch against the downwardly presented shoulder, and fastenings connecting the post to said frames.

4. In a chair, the combination, with a post having in one face thereof upper and lower notches cut on difierent angles with a shoulder therebetween, of a seat frame fitting within the upper notch, an underframe fitting in the lower notch, and means for securing the said frames within the said notches, the securing means comprising a pair of screws extending through the post and into the seat frame and underframe, respectively.

5. A joint for chairs or the like comprising a post having upper and lower notches cut in one side thereof in substantially the same vertical plane and at an angle to each other, an under frame fitting in said lower notch and a seat frame supported on said under frame and fitting into said upper notch, means connecting said under frame and seat frame with said post.

6. In a chair or the like, the combination of a post having a notch therein, a supporting member engaging in said notch, said post having a second notch therein at an angle tosaid first notch and above and adjacent to said first mentioned notch, a seat frame supported on said supporting member and having a part projecting into said second notch, means securing 'said supporting member and seat frame within said notches and means connecting said supporting member and said frame.

7. A oint for chairs and the like comprising a back post, a seat frame and an under supporting frame, said back post having upper and lower contiguous angular notches therein, the upper notch receiving the seat frame and the lower notch receiving the under frame in such a manner that the joint between the seat frame and the back post crosses the oint between the under frame and back post, and means fastening the parts together.

8. A jointforchairs and the like comprismg a back post having upper and lower conaving a notch therein and fitting in said upper notch, an under supporting frame fitting in said lower notch in such a manner that the joint between the seat frame and back post crosses the joint between the back post and under frame, and means fastening the parts together.

9. A joint for chairs and the like comprising a post having angular contiguous upper and lower notches in one face thereof, a seat frame fitting within the upper notch and an under supporting frame fitting within the lower notch and screw means connecting both the under frame and seat frame with said post.

In testimony whereof, I hereunto afiix my signature.
