The main object of this invention is to provide an improved tablet arm chair for school and office work, lunch rooms and the like which may be made largely of metal, is very simple and economical in structure and at the same time comfortable.
Objects pertaining to details and economies of my invention will appear from the descrip tion to follow. The invention is defined in the claims.
A structure embodying the features of my invention is clearly illustrated in the accompanying drawing, in which:
Fig. 1 is a perspective View of a chair embodying the features of my invention.
Fig. 2 isa detail fragmentary inverted view with the legs in section.
Fig. 3 is a fragmentary view in section on line 33 of Figs. 1 and 2.
Fig. 4 is a detail section on line 4P of Fig. 1.
Fig. 5 is a detail side elevation showing details of the support for the tablet arm and of the back.
25 Fig. 6 is a detail section on line 66 of Fig. 1.
Referring to the drawing, the seat 1, which in the structure illustrated is formed of wood, is provided with a supporting ring 2 having so angle-shaped brackets 3 secured on its inner side with the upper legs of the brackets in the plane of the top of the bed ring so that the seat 1 rests thereon as shown in Fig. 3. Screws 1 secure the seat to the bed ring.
The angle iron legs 5 are arranged with their angles facing diagonally inward. The upper ends of the legs are flattened at 6 to conform to the bed ring 2 to the inner side of which they are secured by rivets 7 I pro- 4 vide back supporting bars 8 and 9, also formed of angle iron, these bars being arranged with their angles opening forwardly and in facing relation.
The lower ends of these back supporting 4 bars have forward and inward offsets 10 terminating in attaching portions 11, these offset portions being twisted sutficiently to present the angles of the attaching portions 11 to the rear legs which they embrace and to 50 which they are secured by the rivets 12.
1927. Serial No. 193,240.
The back 13 is arranged between the forwardly facing legs of the back supporting bars and pivoted thereto at 14L This allows the upper end of the back to swing rearwardly, the rearward movement of its lower end, however, being limited by engagement with the inwardly projecting arms of the back supporting bars. The legs are connected adjacenttheir lower ends by the braces 15, an annular brace 17 fitting within and being secured to the cross braces 15 at 18. This provides a very rigid construction.
The lower ends of the legs are upset at 19, these upset portions being suitably conformed to provide suitable feet for the legs.
A tablet arm 20 is supported at its rear end by the bolt 21 which is selectively engageable with holes 22 in the back supporting bar 9. The front end of the tablet arm is provided with a supporting pedestal 23 adjustably mounted on the L-shaped bracket 2%. The horizontal arm 25 of this bracket 24 has a laterally offset attaching portion 26 which is disposed within the angle of one of the front legs and secured thereto by rivets 27 The vertical arm 28 of this supporting bracket 24 has a longitudinal slot 29 therein which is engaged by the bolt 30 through the pedestal so that the front end of the tablet arm 20 is adjustably supported.
With the parts thus arranged the chair may be very economically produced, largely of metal. The structure is strong, durable and comfortable, the back 13 being self-adjusting and swinging on its pivots to conform to the position of the occupant. Below the back 13 is a tie bar 31 which prevents spreading of the upper ends of the back supports.
Having thus described my invention what I claim as new and desire to secure by Letters Patent is:
1. In a chair, the combination of a seat provided with angle iron legs disposed with their angles facing diagonally inward, angle iron back supporting bars disposed in facing relation with their angles opening forwardly and with their lower portions forwardly and inwardly offset and twisted to present the angles of their lower ends in a diagonal relation to embrace the rear legs to which they are secured, and a back disposed between the forwardly projecting arms of the upper ends of said back supporting bars and pivotally mounted thereon, the inwardly projecting arms of said back supports constituting stops limiting the rearward movement of the lower edge of the back on its pivots, the pivots being positioned at the upper ends of the arms so that the rearward movement of the upper edge of the back is not restricted by the ends of the projecting arms of the back supports.
2. In a chair, the combination of a seat provided with angle iron legs disposed. with their angles facing diagonally inward, angle iron back supporting bars disposed in facing relation with their angles opening forwardly and with their lower portions twisted to present the angles of the lower ends in a diagonal relation to embrace the rear legs to which they are secured and a back disposed between the forwardly projecting arms of the upper ends of said back supporting bars and pivotally mounted thereon, the inwardly projecting arms of said back supporting bars limiting the rearward movement of the lower edge of the back on its pivots, the pivots being positioned at the upper ends of the back supporting bars so that the rearward movement of the upper edge of the back is not limited by such inwardly projecting arms.
3. In a chair, the combination of a seat provided with angle iron legs disposed with their angles facing diagonally inward, a back comprislng angle iron back supporting bars securedto the rear legs of the seat, one of said back supports being provided with a plurality of vertically spaced holes, a tablet arm, a supporting bolt for the rear of said arm selectively engageable with said holes in said back supporting bar, a pedestal secured to the under side of said tablet arm, an L-shaped bracket having a laterally ofiset attaching portion at its lower end secured within the angle of one of the front legs, the upright portion of said bracket being vertically slotted, and a bolt on said arm pedestal engaging said slot.
In witness whereof I have hereunto set my hand.
WILLIAM H. MAXYVELL.
