COMBINATION-CHAIR.

Application filed March 5, 1919. Serial No. 280,737.

ahnost entirely of angle and strap-iron or steel, which may be easily adjusted to serve as a stationary chair, a swinging chair, ora sleeping chalr, the back and foot rest be ing capable of different adjustments in either of the above uses of the chair, and which shall be provided with a swinging member adapted to serve either as a table, or.

as an inclined writing desk, or to be swung over so as to cooperate with the back and serveas a head rest when-the chair is usedas a reclining or sleeping chair.

With these and other objects in View I have devised the novel combination chair which I-will now describe, referring to 13116? accompanying drawing forming a partlof this specification: and using reference characters to indicate the several parts;

Figure 1 is a front elevation, the swinging member being in position to serve as a table; 7 f r Fig. 2 a side elevation as seenfrom the right in Fig. 1, the swinging member appearing in full lines in use as a table, and in dotted-lines in use as awriting desk;

Fig. 3 a fragmentary side elevation showing the back and foot rest in a reclining position, the swinging member being shown in position to serve as ahead rest; and

Fig. 4: is a detail perspective view partly broken away illustrating certain details of construction which will be hereinafter fully described. T r

The frame consists of twosidepieces 10 made from strips of angle ironibent to the shape of a broad inverted U and braced 'by' strips of strap iron,-'indic ated by 11. 112 denotes standards extending upward: from the side pieces of the frame and 'formed from strips of strap iron bent to substan tially the shape of an inverted V. 'The standards are braced near the top bycross pieces 13 and a cross piece'l extends over the tops of the standards, the ends of said cross piecebeing bent downward to form Specification of Letters Patent.

lugs 15 in which across rod 16, from which the seat is suspended, oscillates.

Patented May 27, 1919.

The seat comprisesside strips 17 of angle 7 iron to which aboard 18 is secured, andarms 19 formed from pieces of strap iron, the ends of which are curved under the board and. are secured between the angle flanges of the side strips and the board. The seat is suspended fromcross rod 16 by means ofhangers 20, formed from strap iron, the ends of which are secured to plates 21 which in turn are secured to the arms. length of each hanger is looped about the cross rod and is secured thereto, the rod oscillating in lugs 15 when the seat is swung. Below the cross rod, the sides of the hangers are riveted to across brace 22 which insures perfect rigidity of the swinging 'por-' tion of the structure.

The foot rest comprises side "strips 23' formed from strap iron and pivoted to the side strips of the seat, as at 26, the pivot endsbelng given a quarter turn and the ends extending beyond the pivots. The free ends of sald slde strips are bent to formloops 24 1n which the ends of afoot board 25 are secured. .27 denotes crossbraces of strapf iron extending between the side strips which complete and strengthen the foot'rest.

Theba'ckcomprises side strips 28, which The mid aremade of strap iron and pivoted to the side strips of the seat, as at 29, andcross pieces 30, which may be of wood. 31 denotes links, one end of each link being pivoted to the inner end of the'corresponding side strip of the foot rest, as at 32, and the other end being pivoted to the corresponding side strip: of theback, as at 33. These links perform their usual function in reclining chairs and cause the back and foot rest' to swing in unison, the foot 'rest swinging upward when the back is swung downward, and vice versa. rest may be locked at any desired inclination by means of a curved rack 34:, one end. of which is pivoted to one of the side strips of the back, the other end being adapted to slide through akeeper 35 which depends from one oftheangle plates 36, which are secured toarms 19 and serve an'additional The back and foot purpose which will presently be explained.

The operation of the rack and keeper in eon-f nection with the foot rest and back'will be clearly understood from Figs. 3 and 4.

The functions of table, writing desk and head rest are performed by a swinging swing upward and under the cross brace 22' of the hangers.

The swinging portion of the structure,

that is, the seat and cooperating parts, may

be locked in place, either at the upright or a reclining adjustment by meansof aswinging catch 39, which is pivoted to one of" the standards, as at 40, and is adapted to engage a keeper 41 on the corresponding hanger.

In order to give additional rigidity to the structure, when used as anupright chair, I provide anotherswinging catch 42 which is pivoted on one of the side pieces of the frame, as at 43, and is adapted to engage asocket 44 betweenfoot board 25 andthecorresponding side'strip 23.

In order to avoid all danger of the occupant of the chair getting a hand caught be tween a hanger and the corresponding standard, when the chair is swinging, I provideguards 45 which rest upon plates 21 just inside the hangers and are provided withturnbuttons 46 which are adapted to engage the hangers onthe outer side thereof and thus retain the guards in place.

These guards may be made ofcross'veneers of wood, so as to be relatively-light. In fact the structure as a whole combines lightness with great strength as well as convenience in operation.-

These chair are made in different sizesand are equally adapted for children or adults. The smallestsize is admirably adapted for use not only as a swinging or sleeping chair for small children but also as a high chair, so called. In this use the swinging member is placed as in Figs. 1, 2 and 4, the side piecesofthe frame resting inkeepers 51 extending inward from the arms. The board38 is placed in the position shown in Figs. 1. 2 and 4 in which the board lies horizontally and is held against being swung downward by means of pins 47' in the sides of the board which engage recesses 48 inframe 37. In order to prevent the board from tilting upward a turn button 49 is provided on the under side of the board which may be swung under one of the side pieces of the frame. In this position the board serves as a table and in order to prevent things from sliding 0E is provided with a rail 50' around its edge. The board may also be fixed" the same way inlarger sized chairs, but for'use by adults as an inclined reading or writing desk the board will be turned on its pivots and swung backward, as shown by dotted lines in Fig. 2, what wasipr'eviously the-top of thekboard being now the underside and resting against the end of frame 87. Aledge 53 is provided at the lower edge of the board to prevent books and papers from sliding off.

For use as a head rest or an extension of the back, the board is locked in place by. the turn button, as described above, and the swinging member is swung over bodily, the board passing undercross brace 22 of the hangers, and the side pieces of the frame are allowed to rest upon-the top cross piece of'the back, as in Fig. 3.
