Year: 1876

page_text: LETTERS PATENT to George Frederick Redfern, of the General Patent Office,
4, South Street, Finsbury, in the County of Middlesex, Patent Agent, for the
Invention of "AN IMPROVED FOLDING CHAIR OR SEAT." A communication
from abroad by Martial Pierre Bourguet, of 20, Ruc des Petits Hotels, Paris,
in the Republic of France.
Sealed the 7th October, 1876, and dated the 15th May 1876.
PROVISIONAL SPECIFICATION left by the said George Frederick Redfern at
the Office of the Commissioners of Patents on the 15th May 1876.
GEORGE FREDERICK REDFERN, of the General Patent Office, 4, South Street,
Finsbury, in the County of Middlesex, Patent Agent. "AN IMPROVED FOLDING
CHAIR OR SEAT."
In carrying out the Invention communicated to me an ordinary folding stool or
seat having four legs is employed, to which is added a back with two uprights
adjusted by means of suitable joints which attach it to the stool at the height of
the seat, and the lower ends of which rest on two of the rails of the folding stool or
seat in such a manner that all the parts of this improved chair or seat can be folded
together.
SPECIFICATION in pursuance of the conditions of the Letters Patent filed by the
said George Frederick Redfern in the Great Seal Patent Office on the 8th
November 1876.
GEORGE FREDERICK REDFERN, of the General Patent Office, 4, South Street,
Finsbury, in the County of Middlesex, Patent Agent. "AN IMPROVED FOLDING
CHAIR OR SEAT." A communication from abroad by Martial Pierro Bourguet, of
20, Rue des Petits Hotels, Paris, in the Republic of France.
In carrying out the Invention communicated to me an ordinary folding stool or
seat having four legs is employed, to which is adjusted a back with two uprights
adjusted by means of improved joints which connect it with the stool at the height
of the seat, and the ends of which rest on two of the legs of the folding stool
or seat in such a manner that all the parts of this improved chair or seat can be
folded together.

page_text: It will thus be seen that this improved seat differs from the ordinary folding seat
in the combination of its parts, their arrangement, their solidity, and in the addition
of a comfortable back, thereby giving to the chair or seat the advantages of the
ordinary folding seat as well as those of an ordinary chair without the inconve-
niences or disadvantages of the latter.
But to make the Invention communicated to me better understood I will proceed
to describe the same by reference to the accompanying Drawing, in which Figure 1
is a side elevation of the improved folding seat or chair, Figure 2 shews the same
folded up, and Figure 3 is a detached sectional view of the improved joint.
The chair is constructed of four legs, two on each side, as usual. A and B shew
two of the legs of one side, which are crossed, and pivot and turn on the small pins
or axes C, and they are united together by the cross rails or bars a, b, c; D, E,
are the uprights which form the back, and which are united to the other parts
by an improved joint e, Figure 1, shewn detached in full size at Figure 3. It will
be observed that this joint is simple, economical, and strong; it is constructed of a
small iron or other metal plate bent into a half circle and fixed to the uprights D, E,
by means of a bolt or rivet f. A rivetted pin or bolt unites the two sides or arms
by passing through the leg B, which thus oscillates in the joint c. It is to be
understood that the back has two uprights D, E, one on each side of the chair.
Three cross bars or rails unite the two uprights together. The bar or rail
serves another purpose; it takes into a notch (shewn in dotted lines) made in the
leg A so as to form the support or bearing for the back of the chair. A pieco of
cloth, canvas, or other suitable material I forins the covering of the seat, being
wound on the cross rails band d, and the covering of the back is formed by another
piece of similar material connected to the first piece and fixed to the rail h. By this
arrangement of the joint e and the back D, E, the rail g of which rests on the
legs A, a very comfortable chair is obtained, and one which can be folded up, as
shewn at Figure 2, so as to occupy no more space than an ordinary folding seat.
also
Having thus described the Invention communicated to me by my foreign
correspondent, and the best means I am acquainted with for carrying the same into
practice, I wish it to be understood that the details and proportions shewn and
described may be varied without departing from the peculiar character of tho
Invention; but what is claimed and intended to be protected by the herein in part
recited Letters Patent is-
Firstly. The construction of a folding chair or seat having a back, the uprights
of which are connected to the legs by an improved joint, and which rest or bear on
the legs, substantially as herein-before described and represented in the accom-
panying Drawing.
Secondly. The improved joint for connecting the back of the chair to the legs, as
herein-before described and shewn in Figure 3 of the accompanying Drawing.
In witness whereof, I, the said George Frederick Redfern, have hereto set my
hand and seal, this Eighth day of November, in the year of our Lord
One thousand eight hundred and seventy-six.
