CHAIR.

SPECIFICATION formingpart of Letters Patent No. 424,952, dated April 8, 1890. Application filed October 2, 1889. Serial No, 325,756. (No model.)

To all whom it may concern.-

Be it known that I, AUGUST BLUM, a citizen of the United States, residing at Pablo Beach, in the county of Duval and State of Florida, have invented a new and useful Chair, of which the following is a specification.

This invention has relation to invalid-chairs of that class adapted to be converted into a bed and to be inclined to assume different positions for the comfort of the occupant.

The object and advantages of the invention will hereinafter appear, and the novel features thereof will be particularly pointed out in the claims.

Referring to the drawings, Figure 1 is a perspective of the invent-ion, the same being arranged as an ordinary chair. Fig. 2 is a sectional View, the chair being arranged as a bed. Fig. 3 is a detail in perspective of the footrest.

Like numerals of reference indicate like parts in all the figures of the drawings.

1 1 represent opposite side rails, connected at their upper and lower ends by upper and lower cross-bars 2 and 3 respectively, said side rails being formed with slightly offset or angular portions at their lower halves and connected about their centers by a cross-bar 4.. A pair of short bars 6 are pivotally connected at their upper ends to the side bars 1 near their upper ends, and project rearwardly and are connected at their free ends by a cross-bar 7.

8 represent opposite side bars, pivoted near their centers upon the cross-bar 4 and connected at their rear ends by a cross-bar 9, and in front of the same and in their upper edges provided with a series of opposite notches 10, in any pair of which is adapted to rest the cross-bar 7, and thus raise or lower the back section. The front ends of the side bars 8 are connected by a cross-bar 11, and at their centers said bars 8 are slightly bent, so that the rear halves thereof are inclined, while their forward halves are substantially horizontal.

12 represents opposite side bars, the front ends of which are connected by the cross-bar 13, and the rear ends of which are pivoted upon the central cross-bar 4, the bars 12 be ing slightly curved to the front at a point opposite the bend in the bars 8 at their front.

The bars 12 are also chamferedat their under sides and adapted to rest upon a cross-strip 14 and abut against a foot-board 15, extending transversely across the chair and connecting two short foot-bars 16 that are pivoted to the lower ends of the bars 1 and cut away near their pivot points to rest upon the bar 3, which serves as a stop-bar to limit the downward swing of the foot-rest.

The back, seat, and leg-rest of the chair are formedby a suitable fabric or other material and preferably in one piece and in the following manner: One end of the material is cemented or otherwise secured to the central bar 4, passed under the same and up over the bar 2, forming the back 5, at which point it is again e dor otherwi e ecure thence down under the cross-bar 4 and to the cross-bar 11, under and over the same and to the rear, where it is sewed or otherwise sccured to itself directly in front of the central bar l, thus forming a seat 17. After joining at this point the material is carried forward and over the cross-bar 13 .and. back to its point of starting, where it is sewed or otherwise secured to itself, thus forming the leg support 18 and a supplemental seat 19 and when raised a back 20.

As shown in Fig. 1, the seat 17 and back 20 perform its function, and the foot-rest is in position for the feet of the occupant. By removing the transverse bar 7 and placing itin any of the notches desired the seat 17 maybe raised and lowered to suit the height of the person and likewise the inclination of the supplemental back 20. Now, by throwing the back down, as shown in Fig. 2, the leg-supporting section is brought into place, and also the back 5 and supplemental seat 19, and a continuous bed-surface is provided, the section 5 being capable of being adj usted'to give a greater or less inclination.

Having thus described my invention, what I claim is 1. In a folding chair, the combination,\vith opposite pairs of oppositely-inclined side bars, as 1 and 8, pivoted together between their ends and having their upper portions forming a back and seat frame and their lower portions supporting-legs, of an independent swinging frame longer than either the seat or back portions of the chair and adapted to be swung up to form a back or down to form a seat, substantially as specified.

2. The combination, with the oppositelydisposed pivoted side bars 1 and S, the connecting-bar 4, and side bars 12, the free ends of which extend beyond the bars 1 and 8 and have their lower ends pivotally mounted on the bar 4, and the fabric coverings for the bars 1, 8, and 12,0f the lowerbars16, pivoted at their rear ends to the lower ends of the side bars 1, and vertical and horizontal bars 14 and 15 connecting the free ends of the bars 16, and horizontal bar being adapted to receive and support the free ends of the bars 12 when the latter are in a lowered position, substantially as specified.

The combination, with the side bars 1, connected at their centers by the main crossbar 4 and at their upper and lower ends by the cross-bars 2 and 3 respectively, the opposite bars 8, pivoted upon the cross-bar 4 and connected attheir rear and front ends by cross-bars 0 and 11. and provided with aseries of notches 10, the opposite short bars 6, pivoted to the bars 1 and having a transverse bar 7 engaging the notches, of the side bars 12, pivoted at one end to the bar4and projecting beyond and capable of being swung below the horizontal plane of the ends of the bars 11 and connected by a transverse bar 13, and the web, one end of which is fastened to the main bar 4, passed up and over the bar 2, under the bar 1, under and over the bar 11, and connected to itself in front of the bar 4-, thence forwardly and over the bar 13 and up to its point of starting, and there again connected to itself, substantially as specified.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.

AUGUST BLUM.
