UNITED STATES PATENT OFFTCE.
SILAS M. BARRETT, OF CINCINNATI, OHIO.
IMPROVEMENT IN METHOD OF BENDING- yCHAIR-RIMS, &c.
Specification forming part of Letters Patent No. 92,145, dated July 6, 1869.
To all whom lt may concer/n:
Be it known that I, SILAs M. BARRETT, of the city of Cincinnati, county of Hamilton, State of Ohio, have invented a new and improved method of bending strips of wood the thickness oi' which is only two-thirds or less of their width into curves in planes angular to each other 5 'and l do hereby declare that the following is a full, clear, and exact description of the same, reference being had to the accompanying drawings, and letters of reference thereon. Y
It is well known to all engaged in bending Wood that it has heretofore been found difficult, if not impossible, to bend stripsof Wood of the relative thickness and width above mentioned into forms requiring two or more curves in planes angular to each other without their kicking.
This has been the source of serious inconvenience to furniture-makers, who have been compelled to make chair-rims of forms similar to that in Fig. 5, in three pieces, namely, two
side pieces, a d and e l), and a top piece, al c e, to the manifest diminution of the strength ofthe chair-rim. Chair-rims with the curves in two'or more places angular to cach other are easily made when the wood is of nearly, or quite, uniform thickness. But it has beena desideratum in chair-makin g to form a chair-rim shaped and proportioned as above described.
By the method which I have invented and thoroughly tested, the desired shaping of such rims is successfully accomplished.
That method is vas follows: First, I take a piece of wood, A C B, Fig. l, of the length required for the chair-rim, the thickness ofwhich is the width of the rim, and the width of which is equal to several thicknesses of the rim. This I bend into the horseshoe-shape shown in Fig. 2. Second, I then divide it longitudinally by the splitting-saw, or otherwise, into thin strips a c b,Fig. 3. Each of thesestripsis ofthe proper dimensions for the rim a d c e b, Fig. 5, and has one of the curves which is ultimately required impressed upon it. Third, I then bend each ofthe strips into the other curve or curves in planes angular to that of the curveit already has, according to the requirements of the pattern.
Any suitable bending-machine may be used to impress the curves required in the rst and third steps of the above-described method.
I claim as my invention, and desire to secure by Letters Patent- As a new article ot' manufacture, chair backs or rims, constructed as described.
In testimony whereof I have signed my name to this specification before two subscribing witnesses.
S. M. BARRETT. Witnesses:
R. M. RUSSELL, J. T. DILLINGHAM.
