Specification of Letters Patent.

Patented Nov. 16, 1915.

Application filed April 23, 1912. Serial No; 692,675.

sey have invented certain new and useful Improvements in Reclining-Chairs, of which the following is a specification.

This invention relates to that class of reclining chairs in which the seat frame, backframe and leg rest are, or may be, operable simultaneously to shift said parts to different positions of adjustment; a good illustration of this type of chair being found in Patent No. 535,999, dated March 19, 1895.

The object of this invention is to improve the type of chairs referred to in particulars of construction and operation. 7 lVith this object in view, our invention consists in duplicate rectangular hinge frames to be supported by a chair base and adapted to carry the seat-frame, back-frame, leg-frame and the horizontal and upright sections of the arms.

It further consists in mechanism operable by a person while occupying a chair to ad just the seat, back and leg-frames, and the arms by the slight movement of a normally locked lever, and to lockthe parts against accidental movement. I i

It further consists in details of constructi on and in combinations, which will be hereinafter described and claimed.

In the accompanying drawings, illustrating one embodiment of our invention: Figure 1 is a side elevation of a chair, broken lines being used to indicate a different position of adjustment of the back-frame and leg-frame. Fig. 2 is a vertical section of the same, taken through the seat, back and legframes. Fig. 3 is a similar section showing the parts in a different position of adjustment, also showing, insection, a detail of the arm construction. Fig. 1 (Sheet 1) is a detail elevation showing the housing to protect the outer operating gearing. Fig. 5 illustrates a modification. Fig. 6 illustrates, in elevation, and partial sect-ion, the outer operating gearing. Fig. 7 is an enlarged sectional detail of a journal stud of the hinge frame and its bearing. Fig. 8 is an enlarged detail of a part of the rod connecting the lower extension of the backframe and the leg-frame.

The same reference characters are used in the several figures to indicate identical parts.

We employ any suitable base, that here shown comprising two stout side frames A and A rigidly connected together by horizontal braces a. These side frames are provided at front and rear with upward 6Xt811-- sions a and a having bearings A therein, in whichare journaled stub-shafts or studs 1 and 2 projecting from the shorter members 3 and 4 of two hinge-frames comprislng sa d shorter members 3 and 4:, to the ends of which are jointed'the ends of the long upper and lower horizontal members 5 and 6 of said frames.

The seat-frame 7 is securely bolted to the lower horizontal member 6 of the hinge frame, andis carried thereby, and the back frame 8 is in like manner bolted to the rear shorter member 4 of the hinge-frame,'and carried thereby, the upper margin of the legframe 9 being hinged to the forward edge of the seat-frame, as shown in Figs. 2 and 3, and the side bars of the back-frame being extended belowthe seat-frame. c

The forward shorter member 3 'o f the hingeframe are secured the arm pieces 11,

which are provided at their forward ends with recesses 12 to receive the upper ends of the ornamental finishing pieces 10, as shown in Fig. 3. v

To the under side of the seat-frame 7 is secured a rack-bar 18, which is engaged by a toothed cam-shaped segment 14; mounted on a horizontal shaft 15 which is journaled at its ends in bearings secured to the well" forward of the side-frames A A of the base. The shaft 15 projects at one end beyond its bearing, here shown as the right hand end, and rigidly secured to said projecting end is a'half-pinion 16 engaged by a toothed. sector 17 carried by or formed in tegral with the end of a lever 18 pivoted at 19 to the bracket 20 which, as shown in Figs. '1 and 6, carries the bearing for the shaft 15. Pro ecting 'outwardlv from the upper inner cornerof the bracket 20 (see Fig. 6)

is an internally toothed flange 21, curved to an are having its center in the'pivot 19 (which extends through the leg of frame A), the teeth of said flange being engaged by a dog 22 secured to or forming part of a push-rod 23 which is movable longitudinally in guides of the lever 18, and held normally in its uppermost position, with the dog 22 engaging between adjacent teeth of the flange 21, by acompression spring 24: bearing at its lower end on a shoulderof the lever 18, the upper end bearing against a cross-pin 25 carried by the push-rod 28.

From the foregoing description it' wil l be evident that upon pressing upon the top of the push-rod 23 its dog 22 will be freed from the teeth of the flange 21, and that then upon movement of the lever'18'in the direction of the arrow, Fig.1, the seat-frame;

back-frame and arms may be caused to assume the position shown in'Fig. 3, or any,

, intermediate position, and the parts locked by removing pressure from the push-rod.

The s1de piecesof the back-frame 8 are extendeddownward (see broken lines, F 1g.

1) and toth'e lower end is pivoted one end of a connecting rod 26, therouter end of which is adapted for connection with any one of several apertur'esin a bracket27- secured near the lower end of the leg-frame.

VBy this construction the occupant of a chair may adjust the seatframe and back-frame to different positions withoutvleaving his seat, and also adjustjjthe leg-frameby the samemovementof the lever, provided the connectingrod 26' is in engagement with the bracket 27, and not folded back upon itself andsecured to the lower extension of the Nhileit is apparent base-frame.

back frame. The joint 26 of said connecting rod issimilar in operation to the well known jointsin top' propsfor carriages, locking past centers when extended to in sure the extended position of the parts until 35 metal journal-pins 1 and 2 of the metal hinge-frame. Such bearings are illustrated in Fig; 7, and comprise sleevesv 28 flanged at onecend to be inserted inappropriate ertnres in the extensions a of the baseframe. The journal studs 1 of the hingeframe have bearing in these sleeves or bushings, said studs being somewhat shorter than thethicknessof the base-frame exten sions a and having projecting threaded ends upon whichare seated. dished washers 29 bearing upon the surface of said extensions, I nuts3O being threaded upon the threaded I endsof the studs. This arrangement prevents the ournalstuds 1 of the hingeframe from working out of their bearings and tends to strengthen the upper part of the an ornamental stamping 31. I I

To give exterior finish, these parts will be covered at the outer ends by Amodified 'form'of operating devices is shown in Fig. 5, wherein, instead of the drawin s aremerel illustrative of, a racticallyoperating chair, and that in the prac-. ticalmanufacture the frames willbe caned or upholstered, andthe various parts made symmetrical and attractive to the eye.
