Application filed September re, 1016, Serial No. 120,600. Renewed July 9, 1918. Serial No. 244,124.

To all whom it may concern: Be it known that 1, CHARLES I. LATTIG, a citizen of the United States, residing at Bethlehem, in the county of Northampton and State of Pennsylvania, have invented certain new and useful Improvements in Chair Construction, of which the following is a specification.

My invention consists of improvements in chair construction, one object being to make an extremely strong and durable chalr of simple construction.

Another object of my invention 1s to provide a chair with a rail which acts as a con necting member for all of the legs of the chair, and which also serves as a convenient support for the seat of the chair.

' A more specific object of my inventlon Is to employ supporting rails for the seats of chairs, said supporting rails bemg made of malleable metal angle rods which are cut to embrace and secure the legs of the chairs and toform supports for box seats.

A still further object of myinvention is to so cut and secure the angle rod to the legs that the chair may be easily and quickly manufactured and thatthe cost of manufac ture will be comparatively low.

These objects, and other advantageous ends which will be described hereinafter, T attain in the following manner, reference being had to the accompanying drawings 1n which- Figure 1 is a sectional elevation of a chair, constructed in accordance with my invention, taken on the line wa of Fig. 2.

Fi 2 is a sectional plan view takenon the line l) of Fig. 1.

Fig. 3 is a fragmentary perspectlve view showing the manner of cutting, form ng, and securing an angle rod to the leg portlon of a chair made in accordance with my invention, said angle rod forming a connecting rail between the legs of the chair and designed to support a seat or other structure on the chair.

Fig. 4 is a plan view of an angle rod rail which is. cut in accordance with my invention. t F Fig. 5 is a section on the line cc of Fig. 6 is a view of the angle iron rail shown in Fig. 4 as it appears when bent around the leg of the chair.

' portion vertical.

cut away at different points throughout its Fig. 7 is an enlarged section on the line cZ-d of Fig. 2.

Referring to the drawings, 1, 2, 3, and 4 represent the legs of the chair which may be made of pipe and are each provided with floor engaging caps '5. An arm rest 6 connects the upper end of the front leg 1 and the rear leg 4, the latter legand the leg 3 being extended to form supporting means for a back rest 7.

An intermediate leg 8 isfconnected to the arm rest 6 and to a bottom rail, the latter being formed by an angle rod 9 which is secured to the legs 1, 2, 3, and 4, in a manner hereinafter more fully described.

The angle rod 9 has two leg portions 10 and 11 which extend at substantially right angles to each other, the leg portion 11 being substantially horizontal and the leg The leg portion 11 is length as indicated at 12 in Fig. 4', thedesign of this cutting being dependent upon the shape of the cross section of the legs of the chair.

In the present instance, I have illustrated these legs as being circular in cross section, and hence the edges 13 and 14: of the cut away portion 12 are made curved,'"s"o that when the angle is bent around. a respective leg as shown for example in Fig. 6, the edges 13 and 14 will snugly fit against the outer surface of said leg. The edges 15 and 16 forming said out are arranged at an angle which will permit the bending of the angle rod at substantially ninety degrees (90).

The leg portion 10 is not cut away between the edges 13 and l l'but forms a band which embraces the portion of the leg which is opposite from the edges 13 and 14: (see Figs. 4, 5, and 6).

Each of the legs 1, 2, 3, and 4, of the chairs is embraced by the angle rod 9, and the portion 10 of the angle rod is brazed or welded to said legs of the chair at 17. This brazing or welding may be done electrically or by any of the modern methods, such as electric welding, spot welding, or oxy-acetylene welding, so that said welding forms an actual fusingcof the metal of the angle rod and the metal constituting the legs of the chair. This welding may be done neatly, so that when the legs and rail are painted,

, it is practically invisible.

' front portion of the bottom rail as shown at 19 in Fig. 2. The angle rod 9 extends from the intermediate leg 8 around the legs 2, 3, 4, and 1, and terminates at 19 as above described. The angle iron does not encircle the intermediate leg 8 as illustrated, since said latter leg does not extend to the floor level.

In order to form a neat connection between the lower end of said intermediate leg 8, I preferably slot the lower end of said leg 8, the portion 10 of the angle rod extending through said slot as clearly shown in Fig. 7. With this arrangement of the angle bar 9, the portion 11 forms a ledge for supporting panels to provide a box or casing 20. This casing includes a drawer 21.

The upwardly extending le portion 10 of the angle bar or rail 9 is as 'i lustrated, provided with holes through which screws 22 are inserted, said screws acting to secure the casing 20. Another rail '23 of angle bar extends around the legs 2, 3, 4, and 8, the cutting of said angle bar being substantially the same as above described in connection with the angle bar 9, with the exception that the bar engages the intermediate leg 8 in a manner similar to the engagement of said bar with the other of said legs.

'The leg portions 24 and 25 of the angle bar 23 are substantially identical to the leg portions 10 and 11 of the angle bar 9 with the exception that the portion 24 extends downwardly, whereas the portion 10 of the bar 9 extends upwardly (see Fig. l), the portion 25 being cut out similarly to the portion 11 at points adjacent the legs of the chair above mentioned. This bar 23 is welded to the legs 2, 3, 4, and 8, in a manner similar to that described in connection with the welding of the rail 9 to the legs of the chair. The rail or bar 23 thus forms a housing for the upper edge portion of the casing 20, and is provided with holes through which extend screws 26 which secure said upper edge portion of the casing20.

The upper surface of the rail 23 forms a support for a seat 27. Battens 28 are secured to the inner portion of the casing and these battens in turn are screwed or otherwise joined to the lower surface of the seat stamp or cut the angle rods and bend them in their positions with respect to the legs after which they are brazed or welded as above described.

The sections forming the casing 20 may be quickly placed within the recesses provided by the angle rods, and the screws 22 and 26 inserted. The other portions of the chair can be quickly assembled.

A chair constructed as above described may be used in school rooms or for any other purpose where rough usage may be expected, the drawer 21 and casing 20 providing a receptacle for the storage of books or other articles.

Furthermore, with this construction, it is practically impossible for the members to become detached, since the rails after the brazing operation, are substantially integral with the legs of the chair, and thus there is practically no strain on the screws or attaching means for the casing or other elements.

While I have described my invention as taking a particular form, it will be understood that the various parts of my invention may be changed without departing from the spirit thereo and hence I do not limit. myself to the precise construction set forth, but consider that I am at liberty to make such changes and alterations as fairly come within the scope of the appended claims.

Having thus described my invention, what .I claim aS new and desire to secure by Letters Patent is:

1. A chair having a metallic frame including a rail made of angle rod, one of the flangesof the angle rod being cut awa to interrupt it in its length at different olnts, the portions of the other flange adiacentsaid cut away portions being bent outwardly around the chair legs and secured to the latter, said legs also extending through the space formed by the interruption of said flange, and panels supported on said latter mentioned flange and extending between said legs, said legs serving as abutments for the adjacent edges of said panels, substantially as described.

2. A chair having an angle rod bent around the legs of the chair and forming a supporting rail, said angle rod having one of its flanges cut out at difl'erent points to form spaces through which the legs of the chair extend, the other flange at points adjacent th cut out port-ions being bent outwardly around the legs and secured thereto, the flanged portions of said angle rod extending respectively in upward and horizon- ,tal directions to providca recess, a casing including panels fitting said recess and supported by the cut out flange, a second rail comprising an angle rod having its leg portions extending respectively in downwardly and horizontal directions to form a recess to receive the upper port on of said casing, and

a seat positioned above second said angle rod said legs forming abutments for the ends 0 the panels, substantially as described.

3. A chair having a metallic frame including two rails made of angle rod, one mounted above the other. one of the flanges of each angle rodbeingcut away to interrupt .it in its length at diflerent points, portions of the other flanges of each angle rod being bent outwardly around the chair legs and secured to the latter, said legs extending through the spaces formed by the interrl'lptions of said flanges, and panels fittmg 111 between the cut flanges and abutting the legsto form a casing, substantially as described. 15

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.
