FOLDING- CHAIR.

Specification of Letters Patent. Patented June 26, 191?.

Application filed July 17, 1916. Serial No. 109,720.

To all whom it may concern:

Be it known that I; A v'ronr KUozAnmvsKr, a subject of the Czar of Russia, residing at St. Paul, in the county of Ramsey and State of Minnesota, have invented certain new and useful Improvements in Folding Chairs, of

which the following is a specification. This invention relates to new and useful improvements in a folding chair.

The primary obj ect of the invention is the provision of a folding adjustable chaires pecially adapted to be readily: carriepl from place to place for convenient use at such places as picnics and games, the chair affording a comfortable seat when set up in use.

A further object of the device is to provide a chair having a back readily adjusted at a desirable inclination and having resilient supports for the seat portion, the structure being compactly foldable for traveling and storage purposes.

A still further object of the invention is the provision of a foldable chair that possesses great strength and serviceability but is easy and inexpensive to manufacture while affording a comfortable seat when set up for use and consuming but little space when folded. a

With these general 'objects in view and others that will appear as the nature of the invention is better understood, the same consists in the novel combination and arrangement of parts hereinafter fully described, illustrated in the accompanying drawings and then claimed.

In the dI'aWings forming a part of this application and m which like designating characters refer to corresponding parts throughout the several views Figure 1 is aside elevation of the chair.

Fig. 2 is a rear elevation thereof.

Fig. 3 is a view similarto Fig. 1 with the supporting back adjusted at an inclination.

Fig. 4 is a side elevation of the chair in its operative folded position.

Fig. 5 is an enlarged central vertical sectional view through the device, the legs and back being broken away, and

Figs. 6 and 7 are transverse vertical sectional views taken upon line VIV][ and VII-VII respectively of Fig. 1.

The present invention consisting in a foldable chair broadly cosists of a substan -tially square box-shape I frame 10 having the top 11 thereof forming the chair bottom, the said frame-being opened at its under side'for accommodating four supporting legs 12 resilientlymoun'ted therein, an adjustable back 13' being attached to the bottom 11 by means of hlnges 14.

An upholstering mattress 15 extends continuously' from the forward edgeof the bottomll to the upper edge of the back 13 thereby forming an easy seat and .back rest for the occupant of the chair. Side arms 16 are pivoted at their rear ends as at 17 to the back 13 being pivotally connected by braces 18 with the opposite sides of theframe 1.0.

as at 19 and whereby the arms will readily adjust themselves according to the position assumed by the back 13 when moved upon its hinges 14 whether in an inclined position as illustrated in Fig. 3 or inoperatively folded as shown in Fig. 4 of the drawings.

The hinges 11 are attached to the back and extend through slots 19 in the rear upper edge of the frame 10 and are attached to the lower side of the chair bottom 11 by means of the lowersections 20 of the said hinges which are in the form of straps 21 extending forwardly in contact with the bottom 11 to the forward side of the frame 10 and secured to the chair bottom 11 by U-shaped bracket 24 transversely secured to the chair bottom 11 by means of bolts 25 and arranged adjacent the rear side of the frame 10.

A lU-shaped retaining means 26 is pro vided for securing the chair back 13 in adjusted positions and consists of leaf springs 27 secured, as at '28, to the aforementioned straps 21 and having heads 29 at their rear ends, which heads are cbnnected together by a strap 30. The heads 29 are provided with notches or teeth 31 upon their upper sides adapted to receive depending feet 32depending beneath the chair back 13 from the hinges 14. Releasing fingers 33 are outwardly carried by the heads 29 freely pro-- jecting through side openings 34 in the frame 10 at opposite sides of the latter. It will be understood from the foregoing description that by pressing downwardly upon the fingers 33, the feet 32 are released from the notches 31 forpositioning the feet in the notches desired for giving the preferred inclination to the chair back 13, the

45 12 are pivotally attached thereby giving the taining the feet 32 seated within the said notches.

An inverted bracket is carried by the chair bottom 11 oppositely arranged with respect to the rear bracket 24 heretofore set forth, while oppositely arranged flat springs 36 are secured between the opposite ends of the said

brackets

24 and 35. Angle irons 37 are normally arranged flatly positioned upon the said springs 36 being centrally secured thereto by rivets 38, the-said angle irons being thereby supported longitudinally upon the springs 36. The upper angular ends 39 of the chairs legs 12 which are preferably formed of twisted wire are pivotally attached as at 40 to the angle irons 37. A rear angle iron 37 connects the aforementioned side angle irons 37 together and the ends 39 of the front legs being inwardly foldable are prevented from outwardly pivoting by engaging the said angle iron portion 37 forming a stop bar therefor.

The front legs of the chair are inwardly foldable beneath the frame 12 as illustrated in Fig. 4 of the drawings, while the rear legs are similarly folded inwardl preferably over the front legs for retaining the front legs folded, it being noted that the rear legs are provided with a locking wire or tongue 41 which is positionable within a rear notch 42in the frame 10 when the legs are folded and is removably secured in the said notch by means of a pivoted catch 43, it being noted that the tongue 41 is also provided with a hook 44 at its free end for engaging a cross brace 45 which connects the front legs 12 together.

The chair above described when set up for use provides a comfortable seat by means of the upholstering 15 and the adjustability of the back 13 by means of the fingers 33, while the springs 36 form a resilient mounting for the angle irons 37 to which the legs suitable cushioning effect to the bottom frame 10. The back 13 and legs 12 are readsubstantially U shaped ily folded when desired in a compact manner, as illustrated in Fig. 4 of the drawings. The legs are retained folded by means of the catch 43 while a strap 46 is carried by v A strap handle 48 isalso arranged upon the frame 10 whereby the folded chair may be readily carried when desired.

While the forms of the invention herein set forth are believed to be of the preferred construction, minor changes may be obviously made without departing from the spirit and scope of the invention as claimed.

What I claim as new-is:-

1. A chair comprising a bottom. frame open at its under side, opposite inverted U- shaped brackets mounted .within the said frame, fiat springs secured in parallelism between the opposite ends of the said brackets, a U-shaped angle iron member supported upOn the said springs normally positioned in flat longitudinal contact therewith, securing means between the central portions of the said springs and the said angle iron member, and legs carried by the said angle iron member.

2. A chair comprising a bottom frame open at its under side, opposite inverted U- shaped brackets mounted within the said frame, fiat springs secured in parallelism between the opposite ends of the said brackets, a U-shaped angle iron member supported upon the said springs normally positioned in fiat longitudinal contact therewith, securing means between the central portionsof the said springs and the said angle iron member, legs pivoted at their upper ends to the side portions of the said angle iron member within the said frame, the connecting portion of the angle iron member being in abutting engagement with the adjacent legs when the device is operatively positioned.

In testimony whereof I afi'ix my signature,

ANTONI KUCZABOWSKI.
