ADJUSTABLE BOOKING-CHAIR.

Application filed September 22, 1924. Serial No. 739,947.

To all 'whom t may concern: Be it known that I, JACOB A. HILL, a citizen of the United f States, residing at Winston-Salem, in the county of Forsyth and State of North Carolina, have invented certain new and useful Improvements in Adjustable Rocking-Chairs; and I do declare the following to be a full, clear, and exact description of the invention, such as l0 will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to an improved chair and one object of the invention is to provide a chair which may be used as an l5 ordinary rocking chair, as an arm chair with a foot and leg support and back tilted rearwardly as far as desired, and also as a reclining chair.

Another object of the invention is to provide a chair having afoot and leg support of an improved construction, with the footsupporting portion slidably connected with the leg-supporting portion, and to, provide 5y means for controlling sliding of the footsupporting portion is swung forwardly and upwardly byv link members connecting the leg-supporting portion with the tilting back the foot-supporting portion will be ex- -tended and retracted and thus at all times kept in the proper position with respect to the leg-supporting portion.`

Another 4object of the invention is to so construct this chair that the amount of rearby the person occupying the chair and to further so construct the chair that when a person arises lfrom the chair, ar resilient 4 springfmember may pull upon the foot supof a rocking chair but may be readily trans-` formed at will into a lounging cha-ir or reolining chair.

Another object of the invention'is to sov construct this chair that when the back has been swung rearwardly .as far as desired, itr may be firmly braced against additional supporting portion so that when the legrear Seat Posts 3 y omitted and the forward andrear seat r ward incline of the back may be controlled port anddraw it toward 'a retracted posicausing the back to be returned to the norside thereof.

Figure y3 is a vertical sectional view through the chair with the back and leg and foot supports in thenormal position.

Figure 4 is a lview similar to Fig. 3 showing the back tilted rearwardly andthe foot and leg supports swung upwardly to the operative position. n'

This improved chair is provided with a body portion includinga seat frame 1 and seat rails 2 from which extend the front and A andjet braced by the stretchers 5 and carryingthe rockers 6. It

p will be understood that while this chair has b een shown as a rocking chair, the body pors tioncould also be formed after the manner of an ordinary armchair of the non-rocker type in which case the rockers ywould be posts directly engaged with the floor. Arms 7 areprovided at the sides of the kchair body and are suitably connected with the forward and krear arin stands 8 and 9, the forward .arm stand being preferablysecured to the side seat rails and upper endsof the forward seat posts 3 and the rear arm stands 9 being secured upon theseat frame l by suitable fasteners. Bracing rods 1() may also be provided to assist in bracing and supporting thearins.

.The back of this chair is relatively high and is provided with side posts 11 between which are secured the upper and lower back slats 12 and 13,a strip 14 being secured to `lthe inner face of each of the posts 11 between the slats 12 and 13 to properly space f the slats and prevent them from moving toward eachother out of theproper spaced relation. Hinges 15 are carried by the lower back slats 18 and secured to the seat frame l so that this back will be hingedly mounted and may be swung from a vertical position to a rearward incline. The lower end portions of the back post 11 extend downwardly upon opposite sides of the body portion of this chair and are adapted to engage abutment faces 16 formed by recesses in the rear portion of the seat frame 1 so that the extent to which the back may be swung rearwardly may be limited and contacts between the back post and abutment shoulders or faces 16 servepto prevent the back from being accidentally moved'rearwardly beyond a desired amount and the hinges 15 broken or wrenched loose.

The foot and legy rest or support is positioned `at the front of the chair and consists of an upper or outer board or leaf 17 and an inner board or leaf 18 slidably held in engagement with the outer leaf 17 by tracks forming strips 19. These strips. 19 are formed of channel iron and are secured to the side edge faces of the leaf 17 with their flanges extending toward each other over the side portions of the inner leaf as shown in Fig. 2 to slidably mount thev inner leaf. The outer board or leaf 17 is hingedly connected with the seat frame 1 by hinges 2O so that it may be swung vertically and in order to impart the desired swinging movement to this leg support and cause it to be adjusted according-to the position of the back. yThere have been providedV links 21 positioned upon opposite sides of the body portion of the chair and pivot-ally connected with the bearings 22 andv 22 carried by the channelirons 19 and lower end portions of the back posts 11. From an in-` spection of Figs. 1, 3 and 4, it will be readily seen that whenthe back is swung rearwardly fromy the normal position shown in Fig. 3 to that shown in Figs. 1 and 4, the links will be thrust forwardly and they will serve to swing the leg rests forwardly and upwardly. The weight of the leg rest, links and lower end portions of the back posts is such that when not in use, the back may be readily swung upwardly to the vertical position where it will be retained by the false arms 23 which .constitute latch' members.

These false arms are pivotally connectedV withthe back posts 11 and extend forwardly through recesses 24 formed longitudinally in the rear end portions of the arms 7. yThe lower edge faces ofthe falsev arms rest upon the pins 25 extending outwardly from the rear arln stands 9 and notches-forming rack teeth 26 are provided to receive the pins 25. It will thus be seen `that when the back is to be swung rearwardly to an inclined position, the false arms must be raised so that the rack teeth must pass the pins.V Then the back is at the desired incline, itis simply necessary to drop the false arms .and the pins will engage the proper rack teeth and serve to prevent the back from moving rearwardly any further. The teeth may however easily ride over the side pins when the back is returned to the vertical position shown in Fig. 3 and when in this position, the rear teeth of the rack will engage with the side pins and prevent rearward movement of the back until the false arms have been again lifted.

The sliding foot board 18 is to be yieldably held against outward movement and further supported so that when the outer leaf 17 is swung upon its hinges 20, sliding movement will be imparted to the foot board or inner leaf. Therefore, thisfoot board has been provided with slots 27 adjacent its sides and with an intermediate slot 28 between the slots 27. The slot 28 is open at its rear end as shown in Fig. 2 to receive the spring 29, one end of which is secured to a hook or other suitable fastener 30 carried by the outer leaf 17 and the forward end of which is secured to a staple or other suitable fastener 31 driven into the inner leaf at the forward end of the slot 28. This spring` serves to normally kretain the foot board in a retracted position as shown in Fig. 3, but permits it to be swung outwardly when the outer leaf `is swung upwardly. Pulley housings are secured to the rear or underface of the outer leaf .and extend through the slots 27. These pulley housings 32 carry pulley wheels 33 which are engaged by the chains 34e. Each chain 34 is engagedfintermediate its length with its `co-operating pulley wheel and has its end portions extending rearwardly, one end being connected with a hook or other fastener 35 carried by the v foot board 18 and the other end of the chain being secured to a fastener 36 carried by the front seat rail of the body portion of the chair. It will be readily seen that when the leg support or outer panel 17 is swung upwardly, the chains are held stationary at their connections with the fasteners 36 and therefore the chains will be drawn through the pulley housings 32 about the wheels 33 and lwill draw upon ythe footV board and cause it to be slid outwardly to the extended position ,against the action of the spring 29.

When the leg support swings downwardly to the normal position, the spring will be allowed to contract and in doing so will return the foot board to the retracted position. It will thus be seen that there has been provided' a chair which can be used as a rocker with the parts in the position shown in Fig. 3, or the back may be swung rearwardly a` desired amount or for its entire extent and the chair used either as a lounging chai-r or reclining chair, the leg and foot support being of course swung upwardly and the 'foot support extended an amount corresponding to the extent of rearward incline of the back.

While the preferred form of chair has been illustrated and described specifically, it will be understood that this is only the preferred form and that the details of construction may be modified in accordance with the scope of the appended claims.

I claim:

1. A chair comprising a body, a back pivotally connected with said body for swinging movement from an upright to a reclining position, a foot and leg support. including a main member pivotall connected with the front of said body or vertical swinging movement and an auxiliary meniv ber slidably connected with the main member for extension beyond the free end of the main member, means actuated from said back for vertically swinging the main inember of said support when said back is moved, means connected to said body and said auxiliary member for automatically sliding the latter outwardly when the main member swings upwardly, and means for retracting the auxiliary member when the main meinber swings downwardly.

2. The structure of claim l having the means for moving the auxiliary member outwardly consisting of liexible means having one end connected with the auxiliary member and its other end with the chair body, and guide means carried by the main member with the flexible means in sliding engagement with the guide means whereby upon upward swinging movement of the l5 main member pull will be exerted upon the flexible means to draw the auxiliary member forwardly and outwardly.

3. The structure of claim 1 having the means for moving the auxiliary member c means to draw upon the flexible means and f move the auxiliary member outwardly when the main member is swung upwardly.

4. The structure of claim 1 having the auxiliary member provided with longitudinally extending slots adjacent its sides and an open ended longitudinally extending slot leading from its inner end intermediate its width, a spring disposed longitudinally in the intermediate slot and having its rear end connected with the main member and its forward end connected with the auxiliary member, guide pulleys carriedfby the main member and extending through the side slots of the auxiliary member, and flexible means slidably engaged with the pulleys and having their end portions extending rearwardly and connected with the chair body and inner end portion of the auxiliary member.

In testimony whereof I have hereunto affixed my signature.

JACOB AARON HILL.
