TILTING AND RECLINING CHAIR.

SPECIFICATION forming part of Letters Patent No. 366,514, dated July 12 1887.

(No model.)

To aZZ whom it may concern..-

Be it known that we, SANFORD G. SOARRITT and JOHN H. MOsLEY, citizens of the United States, residing at St. Louis, in the State of Missouri, have invented certain new and useful Improvements in Tilting and Reclining Chairs; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

The object of our invention is to secure, in combination, atilting and reclining chair provided with an adjustable head-rest.

The invention consists in the construction and arrangement of its several operative parts, as will be hereinafter shown and described.

In the drawings, Figure 1 is aside elevation of our improved chair in its normal position, showing foot-rest attachment thereon. Fig. 2 is a front elevation. Fig. 3 is a side elevation showing the seat tilted,the back inclined, headrest thro-wn forward, and foot and leg rests extended. Fig. t is a top plan view of the seat-frame with back and arms removed, showing foot and leg rests extended. Fig. 5 is an enlarged view showing in detail the head-rest and operating parts connected therewith. Fig. 6 is an enlarged view of the standard which supports the back and the rightingspring connected therewith. Fig. 7 is a detached perspective view of the leg-rest and connecting parts. Fig. 8 is a detail view of the base of the chair, showing segmental rack and the seat-frame dog, which engages therewith. Fig. 9 is an enlarged detail view ofpiv oted arm-standards and operating parts connected therewith, drawn on line 9 9 of Fig. 10. Fig. 10 is a vertical section of a portion of the arm-standard and connecting parts, drawn on line 10 10 of Fig. 9. Fig. 11. is an enlarged detail plan of a portion of the seat-frame, showing the rack and the lever carried by the transverse shaft.

Like figures indicate like parts.

1 is the base of the chair, having connected therewith vertical post 4. The hub 6, to which supportingarms 7 are rigidly attached, has a rotary movement on the vertical post, said post forming the pivotal center of the chair.

The seat frame 13 is pivoted 'on each side to the supporting-arms, so as to permit the tilting of the seat. The arm-standards 26 are pivoted at the same point. These standards are capable of being inclined rearward, and support the forward ends of the arm-rests 30, the other end of the rests being curved upward and pivoted to the chair-back 32. This back is connected with the scatframe by means of transverse rod 36, passing through standards 34 and cars 38, the standards being secured to the seat-frame and the ears to the base of the chair-back. The righting-spring 37 is spirally wound around the transverse rod, one end of the spring being secured to the standards by tension-collars thereon, the other end resting against the rear of the chairback at its base.

The head-rest 39 is pivoted above the line of its center longitudinally between the extension-pieces 40, secured to the chair-back 82, and is operated by arm-rest 30, through the connecting link 41, said link being pivoted to the'end and lower part of the head-rest and to the rear end of the arm-rest, as shown in Figs. 1, 2, 3, and 5.

The arm-rests are pivoted at one end to the upper part of the standards 26 and at the other end to supporting-brackets attached to and projecting forward from the side bars of the chair-back, a portion of the arm-rests extending beyond the bracket pivot, forming thereby alever-arm, to which the head-rest is connected by links 41. It willbe seen that this construction is an improvement over that shown in Patent 337,521, issued to Sanford G. Scarritt May 9, 1886, as the pivoting of the arm-rests to the projecting brackets carries the pivotal point on said brackets when the back is inclined relatively above the point of intersection of the side bars of the back and the aria rests when both are in their normal position. we thus retain the level of the arm-rests when the back is inclined, secure the desired movement of the head-rest, and prevent any portion the rack-bar.

of the lever-arm or connecting-link thereon from projecting beyondthe 'rear line of the chair-back, and this with shorter arm-rests and connecting links than have been hitherto used for a like purpose.

The leg-rest 20, provided with hinged leaf 23, has ,a back-and-forth sliding movement on flanged slides 17, through supporting-lugs 21. The slides are provided with rack-bar 19, the locking-lugs 22 being held in engagement therewith by the tendency downward of the free or front end of the leg-rest.

The extension of the leg-rest is effected by slightly elevating the front end, thus lowering the locking-lugs below the line of the teeth of \Vhen in this position, the rest can easily be drawn out. The outer or front ends of the slides have a slight curvature downward, so as to provide for the necessary inclination of the leg'rest when extended, as shown in Fig. '3. These slides may be secured to the under side of the seat-frame in any approved rnanner.

The foot-rest 10 is preferably made to fold upon itself. It is pivoted to the two-faced rack-arm 9 on hub 6. The desired position of the foot-rest on this rack-arm is secured by means of dog 11, held in engagement with the rack-teeth by spring 12.

The seat-frame is pivoted between the supporting-arms 7, and held in position by the engagement of dog 15 with the upper teeth on the raekarm 9. The seatris tilted by pressing down on lever 16, fulcrumed on thesupporti ng-arms 7. By this means the free end of the dog arm, which engages with the lever, is lifted and the dog carried out of engagement.

The arm-standards and chair-back are locked in position by spring-dog 27 ,engaging with the segmental-rack 28, rigidly attached to the seatframe. The engaging end of the dog is provided with a recess or slot, into which the lever 24,'carricd on shaft 25, rests. The shaft having a similar lever at its opposite end, the lifting of the dog by knob 29 on either side of the chair carries both dogs at the same time out of engagement and allows the arm standards and back to be inclined.

What we claim as new, and for which we ask Letters Patent of theUnited States, is-

1. The combination, with a seat-fraine, of a hinged back, said back provided with supporting-brackets 42, attached to and projecting forward from the side bars of said back, arm-standards. pivoted at their lower end to the front part of said seat-frame,arrn-rests pivoted at oneend to the upper part of the armstandards and at the other end to the projecting brackets 42, a portion of said arm-rests extending beyond the pivotal point on the brackets, forming a lever end thereby, a headrest pivoted between the upper ends of the side bars of the chair-back, and connecting-links pivoted at each end to the head-rest and the lever ends of the arm-rests, respectively, substantially as set forth and described.

2. The combination, with a seat-frame, of a hinged back, said back provided with brackets 42, attached to and projecting from the side bars of said back, as shown and described, arm-standards pivoted at their lower end to each side of the front part of the seat-frame,
