TO ALL WHOM IT MAY CONCERN:
Be it known Vthat I, J. NICOLALof Boston, in the county of Suffolk, and 'State of Massachusetts, have invented certain new and useful Improvements in Folding Chairs; and I do hereby declare that the following is a full and exact descriptionlthereof. reference being had to theaccompamying dra.w'ings,'and to the letters of reference marked thereon.
The nature of my invention consists in so constructing and vputting together the parts of a. chair that -the whole, when combined, shall constitute a. strong, cheap, and convenient chair, capable oi' being folded into a very compact form.
To enable others skilled in the ort to make and use my invention. I will proceed to describe its construe tion and use.` In the drowings- Figure 1 represents a perspective view of my choir open already for the occupant.
Figure 2 is an elevation of the chatir as it leppears when folded. v
Figure 3 is a. vertical section. l I construct my choir as follows: B B', fig. 1, form the back and two legs, and are framed together by N, and cross-bars O F, iig. 3. A A are two pieces, forming the rear legs of a. chair and part of the arms, being connected together by means of a. rung,-N, nt the lower extremities, and a. rung, L M, neer the upper extremities. The ports A A! are connected to the parts B B by pivots H IPI. C C represent the frame of the sent of the choir, and is hinged, a-s shown in fig. 1, to the parts B B', and being otherwise supported when the choir is open by the rung L M. l) E und D E ore two straps, connected as shown, which keep the rear and front legs of the chair from spreading. In the drawing, I
means of a. rung,
serve as arms and as tensions to have omitted representing the upholstery, as unnecessary.
To fold my chair, I have simply to liftthe seat upwards against the bock of the chair, and drow the legs together, which will conse it to take the form shown in fig. 2.
Having thus described my invention, I will proceed to set forth my claim.
What I claim as my invention, and desire to secure by Letters Potent of the United States, is v The combination of the legs A and B, pivoted at II, the handles D and D", the seat hinged at the rear end,
ed in front upon the rung M, substantially as described and for the purpose set forth.
and support J. NICOLAI.
