Application mea october a1, 1924. serial No. 744,959.

To all whom it may conservo.'

' Be it known that I, HENRY T. TUCKER, a citizen of the United States, residing at Fort Smith, in the county of Sebastian and State of Arkansas, have invented certain new and useful Improvements in a Folding Chair, of which the following is a specification.

rlhis invention relates to improvements in chair constructions.

The primary object of this invention is the provision of a folding chair, which may be folded into a compact iiat'struc'ture, or extended to provide a stable well balanced chair capable of supporting persons of eX- treme weight, due to the sturdy and effective manner of securing the parts.

A further objectyof this invention is'the provision of a folding chair, which includes parts whichl are movably connected by wooden parts, in a novel manner, so as to r dispense with castings, and other metal dit clips and parts which occasionally become loosened, bent, and detached.

A furtherobject of-this invention is the provision of a'folding chair which may be easily extended or collapsed.

A further object of this invention is the provision of a novel chair structure including a back portion cooperably associated with the seat structure thereof so that thev back portion will assume a comfortable rigid position with respect to the seat when the chair is extended and folded into substantial parallelism' with the seat when the chair is folded into a flat compact structure.

Other objects and advantages of this invention will be apparent during the course of thefollowing detailed description.

ln the accompanying drawing, forming a part of this specification, and wherein similar reference-characters designate corresponding parts throughout the several views,

Figure 41 is a cross sectional view taken longitudinally through the chair in its extended relation.

Figure 2 is a similar cross section of the tion.

Figure 3 is a fragmentary view, partly in cross section, of the upper front corner of the chair when the parts thereof are collapsed.

Figure 4 is a rear elevation of the chair in folded position.

i chair parts with the chair in collapsed posi-- I n the drawing, wherein for the purpose of illustration is shown a preferred embodiment of this invention the letter A may generally designate the chair which may inn clude a supporting structure B; seat C; and back D.

Referring to the supporting structure B, the same provides a pair of side bars or

members

15 and 16, which at their lower portions provide legs 17 and 18 respectively, and at their upper portions provide the

back rails

19 and 20 respectively.

Front legs

21 and 22 are respectively provided for pivotal connection to the legs 17 and 18 by means of a cross bar 23, so that the

legs

21 and 22 are e'ectively pivoted inwardly of the legs 17' and 18, and whereby when the chair is in position for seating purposes the pivot cross bar 23 will be disposed below the seat @substantially midway of the forward andrearward parts thereof, so that the ends of the-frontend rear pairs of legs are suitably distanced to properly and stably support the chair. p

llnwardly of their facing inside surfaces the

back members

19 and 20 are provided withk longitudinally extending grooves 24 therein, provided for urpose of guidingnt'he operation of the seat as will be described.

Referring more particularly to the seat structure C, the same includes the

side rails

30 and 31, with the front and rear main supporting

bars

32 and 33 extending between the same and axed therein in any approved manner. The seat slats 35 are provided in any approved number, at their..

edge being supported in grooves provided lat the inside surfacesl of the

rails

30 and 31, and preferably assisted in their support by the main front and rear supporting mem- :

bers

32 and 33. This provides a very durable construction.

At its forward end, and preferably below' the slat 35 immediatel adjacent the supporting bar 32, a pivot race 38 is provided, extending transversely through the rails or

members

30 and 31 of the seat C, and pro'- viding projections which are pivoted in the these projections 40 and 41 preferably supporting pins 42 which project laterally of their respective projections for slidable disposition in the grooves 24. These pins 42 it should be noted are not at the extreme rear ends of the

rails

30 and 31, but permit said rails to project beyond the

back rails

19 and 20 when the seat is in horizontal position.

For its horizontal rest-ing position the seat is supported by means of the pins 42, which rest in the lower ends of the grooves 24, to properly brace the pairs of front and rear legs to hold the seat in such position.

The back D in addition to the

rails

19 and 20 above mentioned includes the swinging back portion 45, which consists of the top cross member 47 at its ends being pivoted by spindle extensions 48 in the upper ends of the

rails

19 and 20, so that the back portion 45 may swing to permit the proper folding and unfolding of the chair. The back portion 45 furthermore includes the vertical slats 49, which at their lower ends are connected by means of a short cross piece 50, which is not connected to any part of the chair. except to the slats 49.

The ends of the

seat rails

30 and 31 which extend beyond the

back rails

19 and 20, when the seat is in horizontal position, as is illustrated in Figure 4, support a cross bar or piece 53, in spaced relation with the rearmost seat member 33 and the axis of which cross rail 53 is disposed below the lane of the seat formed by the slots 35. T e lower swinging end of the back 45 is disposed in this opening 55 between the seat member 33 and the retaining bar 53, to guide the back portion 45 into its folded or vunfolded. seating relation. A

At its upper end the chair is preferably provided with a hand grasping cross bar 58, connected in the

back rails

19 and 20 at the very upper ends thereof. Across brace is similarly provided at the lower ends of the rear le s 21 and 22.

From the oregoing description of this invention the operation will be obvious. Assuming the chair to be in seating osition, vas is illustrated in Fi ure 1, in order to fold the same it is mere y necessary for the operator to grasp the cross piece 58 with his hand, and by placing his foot on the cross rail 60 and pulling upwardly, the seat C will be (pivotally swung upon its pivot piece` 38,I an

the pins 42 will slide upwardly in the groove'24, to permit the rear legs; the seat; and the back portion 45 to fold into flat collapsing relation within the area formed by the outer margins of the

bars

15 and 16, and as is illustrated in Fi re 2 of the drawings. The back portion 45 1s guided in its folded or unfolded position by means of the bar 33 and the cross piece 53, and the back is folded in a plane substantially parallel with the seat when the chair is folded, and when the chair is unfolded the back is slightly tipped rearwardly at its lower end to place the same in proper posture for comfortable seating purposes. It is to be noted that all of the chair parts are formed of wood, even the bearing pins and cross braces. The parts may be made `of metal if desired, although the use of clips and metal castings is 'obviated by the structure shown, thus providing a chair which is relatively simple to construct, economical to manufacture, and which may be easily folded or unfolded. As for the unfolding of the chair it is merely necessary fo-r the operator to grasp the same by the rail 58 at the top of the chair, and by swinging the chair outwardly at its lower end and hitting the lower ends of the rear pair of

legs

21 and 22 on a floor surface, with the front of the chair facing the person, the chair will immediately become unfolded.

Various changes in the shape, size, and arrangement of parts lmay be made to the form of the invention herein shown and d`e' scribed, without departing from the spirit of the invention or the scope o-f the claims.
