FOLDING CHAIR.
SPECIFICATION formingpart of Letters Patent No. 635,486, dated October 24, 1899.
Application filed August 26, 1898.
To all whom it may concern:
Be it known that I, HEINRICH LUDWIG CARL FRIEDRICH IHDE, a citizen of Germany, residing at Hamburg, in the German Empire, have invented certain new and useful Improvements in Folding Chairs, (for which I have applied for a patent in Germany, dated January 5, 1898, and in France, dated May I, 1898,) of which the following is a specification.
The object of the present invention consists of a chair which without the agency of springs folds together upon being raised by the back and which assumes the position of use upon being again placed upon its fore legs.
The chair is specially suited for manufacture on a wholesale. scale in consequence of its simplicity. It can be made of dimensions suitable for any weight.
Upon the accompanying drawings one form of the invention is shown.
Figure 1 represents a side elevation of a chair in the position of use. Fig. 2 is a side elevation of a chair in the closed position. Fig. 8 is a front elevation of Fig. 1.
As will be seen from the drawings, this chair consists, essentially, of the frame 19, connected to the back a, and of the frame 0. A spindle d connects the frames band 0, forming the legs of the chair, together. These frames are eccentrically pivoted, so that upon raising the part a b the other part 0 extends below the bottom end of the same, Fig. 2.
The seat proper, e, has two pieces of fiat iron are bent into a semicircular form and engage the transverse rods 0 b, and thus hold the seat more securely in connection within the frames 0 and 12 according as the weight increases.
In addition to the flat irbn pieces mentioned above strengthening-pieces g are fitted to the under side of the seat, and a round angle-rod iis pivoted to the strengthening-pieces by Serial No. 689,584:- (No model.)
means of eyelets. The other ends of the rod 1' are pivoted to the spindle (Z.
A chain Z connects the seat with the frame 0, regulating the motion of the former. The chain is connected to the transverse piece k of the seat. A rod m strengthens the frame I) and serves as a bearing for the rod i.
The action of the chair is as follows: The bent ends of the fiat iron pieces f engage when the chair is in the position of use the transverse rods 0 and b of the frames 0 and b. The iron rod 1' transfers the load of the seat to the spindle d and also to the legs of the chair. Upon raising the chair by the back the ends of the flat iron pieces f are brought out of engagement with the cross-rods. The seat consequently falls backward and is supported by the iron rod t', and thus prevented from falling entirely, resting against the frame b.
In the closed position the chair occupies but little space and by being simply placed upon the legs 0 opens out into its position of use.
What I claim, and desire to secure by Letters Patent of the United States, is
1. In a folding chair, the combination of the two leg-frames b and c eccentrioally pivoted together and provided respectively with the cross-rods b and c, of a seat provided with front and rear hooks reversed with respect to each other, and adapted to engage the cross rods respectively, substantially as described.
2. In a folding chair, the combination of the two leg-frames b and c, a cross-spindle to which said frames are eccentrically pivoted together, a seat, and bent arms 11 and chain by which the seat is connected to the spindle, substantially as described.
In testimony whereof I have hereunto set my hand in the presence of two witnesses.
HEINRICH LUDWIG CARL FRIEDRICH HIDE.
Witnesses:
AUGUST LiiHRs, E. HH. MUMMENHOFF.
