When it is desired to-hold the chair rigid then the hook arm 24 may be engaged in the keeper 23. In Figure it will'be seen that the brackets 11. have arms 12 pivoted thereto and coil springs 4L0 are secured to the arms 12 as is shown toadva'ntage in Figure 12 and are secured by welding as is indicated at 41 to the uprights 5.

In Figures 14 and 15 it will be seen that arms 12 are pivoted in brackets 11 welded'to uprights 5" and arcuate depending extensions 14; have reduced ends 42'welded in springs 5 .3 which are welded to the uprights 5 The function-of springs and 43, of course are the same as the function of the springs 28.

It is thought that the construction, opera: tion, utility'and advantages of the invention will now be quite apparent to those skilled in this art Without a more detailed description thereof. i

The present embodiments of the invention have been disclosed in considerable detail merely for the purposes of exemplification since in actual practice they attain the features of advantage enumerated as desirable in the statement of the invention and the a above description.

It will be apparent that changes in the details of construction, and in the combination and arrangement of parts may be resorted to without departing from the spirit or scope of the invention as hereinafter claimed or sacsecured in the frame, arms pivotally engaged between the extremities of the brackets, de-

pending extensions on intermediate portions of the arms, a foot rest between the extensions, brackets mounted on the frame above the arms, springs engaged with the last mentioned brackets and with the foot'rest, adjustable means for securing the springs to the foot rest.
