Roy H. Williams, Taunton,‘ Mass. 1 '
Application March 1, 1937, Serial No; 128,302
3 claims. (01. 155-491)
'
This invention relates to chairs and more par
ticularly to chairs used on lawns, piazzas and 'lik
places, usually made of wood;
'
One object of my invention is to provide a
chair the main supporting parts of ‘which are
so interlocked ‘with each other as to result in a
rigid construction that will not permit any side
or forward or backward weaving of saidparts
which is so common in wooden lawn chairs.
A
10 further object is to so form the parts of said
chair that they may be cut from lumber by
quantity production machinery with such uni
formity and interchangeability that they may
be assembled and completed by relatively, un
15 skilled labor, with the result that a chair is pro
vided that is comparable in strength and rigidity
with high priced chairs and whose production
cost is substantially that of the lower priced
chairs.

‘
liia and the secondi‘one in from the front of my
chair beingltb. Said slats are mainly support
ed by said cross bars M. A back I1 is also pro¢
vided which is preferably made of a plurality of
*
slats as shown. Arms lS'eXtend from eachisaid 5
front leg to and beyond each rear leg, and are
fastened to said legs by pin means as at l9, which
arms support a transverse'brace 2! extending be
tween them'at the rear of said back ll.
Below
,
said transverse brace 2! are reinforcing mem- 1'0
bers 22 which’ extend diagonally across from one
said leg to another. At the front of said front
legs i2 is- a reinforcing piece 23 which is fastened
to said legs ‘I 2 and extends from one to the other
and is substantially ?ush with their outer sur- 15
faces.

In order to strengthen my chair and to pre
vent any weaving or loose movement of the parts
bearing the greatest strain, each of said legs
The foregoing and other objects'which will 7 l2 and E3 is provided with a recess 25 cut or
appear as the nature of the invention is better otherwise formed in‘the inner side surface in
understood, may be accomplished by a construc
termediate' the top. and bottom edges of said
‘ tion, combination ‘and arrangement of parts such
legs, which recesses 25 extend diagonally down
ward from front to back, and in which end por
as is disclosed .bythe drawing and speci?cation.
25 The nature of the invention is such as to‘ render ' tions of said cross bars M‘?t, as shown in the
it susceptible to various changes and modi?ca
tions, and, therefore, I am not to be limited to
said disclosure; but am entitled to all such,
changes therefrom as fall within the scope of my
claims.
In the drawing:
Figure l is a perspective view of my chair.
Figure 2 is a view partly in section taken on
the line 2—2 of Figure l with the front slat of
35 the seat and the front reinforcing piece omitted
to more clearly illustrate details of construction.
Figure 3 is a View partly in section taken on
the line 3-3 of Figure 1.
V
Figure 4 is a sectional View taken on the line
40 li-|l of Figure 1.
Figure 5 is a View partly in section showing
a View similar to Figure 3 of a modi?ed con
struction.
As illustrated my chair, has two front legs 12,.
45 and two rear legs 53, each pair of said front and
rear legs being preferably opposite or in aline
ment with’ each other, and each said pair hav
ing a cross bar it extending between the legs,
'50
which bars M are leveled off as at lilo, at their
front ends, the end portions of said cross bars
iii preferably being bolted as at l5 to said front
and rearlegs.
A seat l5, commonly made of a plurality of
slats, has a front portion shown in the form
55 of two separate slats the ?rst or front slat being
drawing. Said recesses 25 are quite shallow and
only that partof said cross bars is representing
a small fraction of their thickness extend into
said recesses. As will be seen the bottom sur
faces of said cross bars l4 in said recesses 25 bear
against the lower shoulders 26 which the cut-out o: 0
portions 25 provide in said legs, whereby said
cross bars M are actually supported by portions
of said legs 12 in the'form of said lower shoul
de'rs 26, instead of depending upon bolts to hold
said cross bars and legs together as heretofore. 66 5
This construction prevents any appreciable for
ward or rearward movement of said front and
rear legs 12 and E3, or anyvertical movement
of said cross bars Ill, whereas in the common
construction of such chairs the Crossbars rest
?ush against the inner surface of said legs, and
said legs and cross bars may move somewhat
relative to eachother even when the bolts l5
holding them together are tight. It is the loose- 45
ness, which develops while in use, between said
legs and said cross bars which is the bane of this
type of chair. While the said recess 25 in a said
front leg I2 is in the upper portion thereof, and
the recess 25 in a said rear leg is in the lower
portion thereof as shown in the drawing, as a
matter of fact the distance from said recess to
the top edge of a said front leg is the same as
the distance from said recess to the bottom edge
of a said rear leg whereby a front leg is inter 55

changeable with a rear leg, in other words a leg
a said front leg l2, in which construction the
may be used as a front or as a rear leg, thus
cross bars do not extend into said cut-out por
simplifying production as Well as reducing the
number of different parts which go to make up
tion 30. Also the ends of said seat front slat
I6a extend in front of each said front leg l2
and are substantially flush with the outer side
surfaces of said legs l2. This is made possible
by lengthening said slat and in this longer por
tion l?aa a cut-out portion 3| is provided at the
extreme ends thereof, the front and inner sur
faces of said front legs bearing against said
cut-out, portion 3! as shown in said Figure 5.
my chair.
To further strengthen my chair the second slat in from the front of the chair l6b,
which constitutes part of the front portion of
said seat l6, has a cut-out portion 28 at each
10 end, said cut-out 28 extending from the front
edge of said slat l6b rearwardly a short distance
and forming a right angle as illustrated in Fig
ure 3 of the drawing. This enables one to ?t
the slat IBb against the front legs whereby the
15 cut-out end portion 28 extends within and bears
against the inner side surface of each said front
leg l2 while the remaining portion of said out
out 28 continues at right angles and bears against
the back end surfaces of said front legs l2, as
20 illustrated at 29 in Figures 3 and 5 of the draw
ing, thereby further reinforcing and making more
rigid said front legs l2 by means of said seat
portion IBb‘.
Chairs have a tendency to weave or rock espe
cially at their front portion and in order to in
crease the rigidity of the front portion and espe
cially the front legs I2, I preferably cut out at
each end of said front reinforcing piece 23 a
portion of the inner surface as illustrated in Fig
30 ure 3 of the drawing, said cut-out portion be
ing represented by the numeral 30. It extends
inwardly from the extreme ends of said front
reinforcing piece 23 only far enough to permit
said front legs l2 and the front ends of said
35 cross bars I4, to enter said front reinforcing
piece 23, the inner side surfaces of said cross
bars [4 bearing against the shoulder 32 formed
at the inner termination of said cut-out portion
30 as shown in Figure 3 of the drawing.
40
In the modi?cation shown in Figure 5 of the
25
- drawing the cut-out portion 30 is only large
enough to accommodate and permit the entry of
What I claim is:
l. A chair comprising two front legs and two
rear legs with bars extending between the front
and rear legs and to the front edges of the 15
front legs, said bars being secured to said legs,
and a reinforcing piece extending between said
front legs and having rebated extremities into
each of which a front leg and the extremity of
20
one of said bars secured thereto, is ?tted.
2. A chair comprising two front legs and two
rear legs with bars extending between the front
and rear legs and to the front edges of the front
legs, said bars being secured to said legs, and
a reinforcing piece extending between said front 25
legs and having rebated extremities into each of
which a front leg and the extremity of one of
said bars secured thereto, is ?tted, said bars ex
tending diagonally downward from the respec
tive front legs, to the rear legs.
3. A chair comprising two front legs and two
rear legs with bars extending between the front
and rear legs and to the front edges of the
front legs, and a reinforcing piece extending
between said front legs and having rebated ex 35
tremities into each of which a front leg and the
extremity of one said bars secured thereto, is
?tted, said bars extending diagonally downward
from the respective front legs to the rear legs
and ?tted in diagonal recesses formed in the
inner sides of said front and rear legs.
