The uprights l3 are located substan- A spring 60 is connected at 6| to the rear end 50 tially vertically while the uprights [4 are inof the rack 50 while the opposite end of the spring clined at an angle to the horizontally disposed is connected at Glen to the un-derface of the board base member Ill and lean rearwardly from the or bar 3 I. This spring tends at all times to move chair. the rack 50 rearwardly for a purpose which will be i 55 A back frame, generally designated by the nupresently explained. 55

Brackets are secured to the plates 54 in such a manner that the rack 50 is disposed between the brackets. Bearings 66 are formed in the brackets to receive a rock shaft 61 which has a crank 68 located between the standards and in a position to engage the curved pockets between the teeth 5| of the rack 50. A coil spring 10 is disposed on the shaft 61 and has one end connected at H to the shaft. The other end of the spring, as shown at 12, is connected to an adjacently disposed bracket 65. Thus it will be seen that the shaft will be maintained in a predetermined position so that the crank 68 will tend at all times to move into engagement with the teeth 5| of the rack.

The rock shaft 61 extends from the center towards the side where it is provided with a handle, as shown at I3. The handle is adapted to be grasped by the occupant of the chair for releasing the crank 68 from its engagement with the pockets of the rack whereby the back may be moved to a different angle. Some form of operating rod or chain may be connected with the handle 13 and disposed adjacent the arm rest l5 of the chair and in a position where it may be conveniently grasped by the occupant.

The operation of my device is as follows: In Fig. 1 the movable back 20 is in a position where it will normally be retained in position by means of the crank 68 and the spring 60, since the spring tends to move the rack to a position where the frame 20 will be in its normal reclining position. At this time, the rear end of the rack 50 will be in engagement with a stop 15 which is secured at 16 to the board or plate 35. If it be desired to move the back to a position where it will have a greater angle of inclination with respect to the base frame II] it is only necessary for the occupant to grasp the handle l3 and rock the shaft 61 whereby the crank 68 will be released from the teeth 5|. By throwing sufficient weight against the back 20 which is now free, the back will be moved to a greater angle with respect to the base member ID and when the desired position has been reached the handle 13 is released whereby the crank 68 will snap into position between a pair of teeth 5| of the rack 50.

When it is desired to return the back frame to its normal position, it is only necessary to remove any pressure from the back so that when the handle 73 is manipulated and the shaft 61 rocked, the crank 68 will be released from the rack and the spring will move the rack rearwardly to cause reciprocation of the links 46 and rocking of the rods 40 whereby the back will be moved upon its pivots 26 until it reaches the normal position shown in Figure 1 or any position desired.

I claim:

A reclining chair comprising a supporting base frame, a movable back frame having side bars pivoted-at the lower end thereof to the base frame, said back frame having vertically spaced cross bars provided with aligned passages which are located medially of the ends of the cross bars, rods fitted insaid passages secured to one of the cross bars and having ends projecting below the lower cross bar, said ends being split, a rack slidably mounted longitudinally of the base frame, guides for the rack, a link at each side of the rack and having pivotal connections therewith, said links being straight and parallel to each other for a portion of their backwardly extending distance and then bowed outwardly from the rack into line with the splits in the projecting ends of said rods, means pivotally connecting the links in said splits, resilient means tending to move the back frame to its normal position, and means carried by the base frame which is operable in respect to the rack to hold the back frame in adjusted position.
