METALLIC TUBE.
Speceation of Letters Patent.
Fatented Feb. I2, 1Min.
Application filed J une 8, 1916. Serial No. 102,484.
To all whom t may concern.'
Be it known that I, ALBERT L. ADAMS, a citizen of the United States, residing at Cedar Rapids, in the county of Lynn and State of Iowa, have invented certain new and useful Improvements in Metallic Tubes, of which the following is a specication, reference being had therein to the accompanying drawing.
This invention relates to improvements in furniture, one object of the inventionbeing' the provision of metallic legs and frames for tables, chairs, bedsteads and all classes of metallic tubes, that are made from sheet metal bent to provide incased integral reinforcements, so that the legs cannot be easily bent or twisted, and are made practi cally unbreakable.
In the accompanying drawings z* Figure l is a perspective view of a chair, the legs of which are made according to the present invention.
Figs. 2, 3, 4 and 5 are cross sections through various leg and frame construc tions.
Referring to the drawings, the numeral 10 designates the legs of the chair, which may be taken as indicative of any form of furniture supported upon legs.
In the construction shown in Fig'. 2, the tubular member 10f is provided with the inwardly bent flanges llf, while reinforcing the tubular member throughout the length thereof is the reinforcement 15 which is centrally looped and provided with the oppositely disposed curved terminals 16 which fit adjacent the edges 11t and thus brace the member 10t at three points.
In the construction shown in Fig. 3, the reinforcement 15 has the larger main loop in contact with the inner wall of the incasing member, while the hooked terminals 16 are similar to the ones shown in Fig. 2.
In the construction shown in Fig. 4, the
toptien et this patent may be reinforcement 15 is provided with the hooked terminals 16 and with the inverted inwardly bent portion 17 longitudinally of the loop.
In Fig. 5, the outer casing 10g is provided with the inwardly bent terminals 11g, while incasing said terminals is the member 18 having the straddling terminals 19 and the tubular connecting portion 20, which provides a relatively wide bearing surface between the extreme edges of the terminals llg and the inner face of the incasing tube 10g.
Vhere so desired, the reinforcing member 11g may be compressed to lit co-eXtensively throughout the length of the member.
The reinforcing members 15, 15', 15, and
a 18, are each made from a single sheetof metal so that the complete structure is really made of two sheets of metal when fully assembled.
Although the description has been particularly directed to chair and table legs, it is apparent that this form of tubular construction may be used for the back frame, seat frame, and rungs of a chair, for legs and frames of tables, and for the complete head and foot frames of a bed.
Vhat I claim as new is A metallic tube, including one sheet of metal bent in tubular form and having the edges thereof projected inwardly and longitudinally of the tube, and a second sheet of metal bent to provide straddling terminals for receiving the edges of the first sheet when the second sheet of metal is telescopically fitted within the first sheet, the connecting portion between the 'straddling portions of the second sheet being bowed to provide a relatively large surface contacting portion for engaging the inner face of the first sheet.
In testimony whereof I afix my signature.
ALBERT L. ADAMS.
