Each side frame 2 is 45 sion device by means of which the chair-body also provided in its upper front and rear poris niovably suspended upon the base; and Fig. tions with suitable perforations which form I; is a plan or top view of the base and the suitable bearii'igs fora set of four hangers 6. a a.

said hanger mechanism or suspension device, Each hanger, as will be seen from Fig. 5, conthose portions of the chair-body with which sists, essentially, of a horizontal journal or a 5 said device is operatively connected being bearing portion T, adapted to be arranged in 0 a perforation 5, with a shoulder or flange 8 arranged directly against the inner side of the frame 2, as illustrated in Figs. 2, 3, and 4, and the lower end of each hanger 6 is made with a horizontal sleeve 9 and provided with a set-screw 10. From an inspection of Figs. 3 and 4 it will be seen that there is one pair of hangers at the front and one pair of hangers at the rear of the base 1, and the sleeves 9 of each pair of hangers are arranged and held bymeans of the said set-screws on suitable hanger rods or bars 11. Suitably secured upon each end of the rods or bars 11, by means of set-screws 13 or in any other manner, are the sleeves 12, which extend into and through the respective openings 4 in the said frame 2, as shown, each sleeve 12 being made with a bearing portion or journal 14 and an annular shoulder or flange 15. as clearly illustrated. The said bearing or journal portions 14, as will be seen more especially from an inspection of Fig. 3, are arranged in perforations 18 in the frame portions 19 and 20 of the chair-body 17.

In assembling the parts the journal portions 14 of the sleeves 12, which are loosely arranged upon the respective end portions of the hanger-rods 11, are arranged in the perforations 18 above mentioned and slipped upon the rods 11 until their shoulders or flanges 15 rest against the inner surfaces of the frame portions 19 and 20, and the set-screws 13 are then tightened to retain the said sleeves 12 in their adjusted and rigidly-connected relation upon the ends of the said rods 11. The hangers 6, which have also been loosely arranged upon the rods 11, are now slipped forward upon their respective rods and their journal portions 7 arranged in the respective perforations 5 in the side frames 2 in the manner hereinabove set forth, and the hangers 6 are then secured in their operative positions by tightening up the screws 10, as will be clearly understood. It will thus be evident that the various parts are separably connected in their adjusted and operative positions when the'chair-body is suspended in its swinging position above the base 1, and by simply loosening the set- screws 10 and 13 the hangers 6 and sleeves 12 can be slipped back and forth upon the respective rods 11 for removing the chair-body from its suspended position or for securing it in its suspended relation without being compelled to take the framework of either the chair-body or the base apart.

The chair-body is operated by the occupant in the usual manner by a slight forward and backward motion. To look the said chairbody in any one of the angular positions against further swinging movement, I have provided the chair-body with a locking device, clearly illustrated in Figs. 1, 4, 6, 7, 8, and 8. This device consists, essentially, of a cylinder 21, which is arranged in an opening in the frame portion 22 of the chair-body, the said cylinder having an ornamental plate 23, which is secured over the said opening upon the outside of the said frame portion 22, as represented in Fig. 1. Secured to the open end portion 24 of the said cylinder 21 is a ring or sleeve 25, having the sharp holding edge 26, the said open end portion 24 and sleeve 25 projecting from said opening in the frame portion 22 upon the inner surface of the said portion 22, as shown. Movably arranged in the open end of the said cylinder 21 is a plunger 27, having a stem 28 within the cylinder, the upper end of said stem being movably arranged in and extending from a guide-opening 29 in the closed end of the cylinder. Pivoted to the free end of the stem 28, upon a pin 30, is a cam-lever 31, having a cam-shaped head resting in the curved and depressed part 32 of the closed end portion of the cylinder, as clearly represented in the drawings. The stem 28 is also encircled by a coiled spring 33. The plunger 27 is made with an opening 34, in which there is a pin 35 and a grooved roller 36, said roller being preferably made of hard rubber. Pivotally arranged upon a bracket 37 upon one of the side frames 2 is a curved rod 38, the said rod-extending through the opening 34 and under normal conditions, While rocking and when the parts of the locking device are in the positions indicated in Fig. 6, moving freely upon the roller 36. When, however, the cam-lever is turned into the position represented in Fig. 7, then the plunger 27 will be drawn farther into the cylinder, whereby the said rod 38 is drawn toward the sleeve 25, thereby bringing certain serrations 39 on said rod 38 in holding engagement with the sharp holding edge 26 of the sleeve 25, as clearly illustrated in Fig. 7 of the drawings, and the chair-body will thereby be held against any swinging movement until the cam-lever 31 is again thrown back into its initial position, (indicated in Fig. 6,) and the coils of the compressed spring 33 will once more force the parts to their normally inactive positions, thus leaving the rod 38 to move freely back and forth upon the roller 36, so as not to interfere with the swinging movement of the chair-body.

If desired, bearings 40 may be secured to the framework of the chair-body, and a footrest 41 may be pivotally arranged between said bearings. Pivotally connected with the said rest 41 is a bar 42, having ratchet-teeth 43, said bar extending in a rearward direction and being slidably arranged in an oscillating box 44 at the side of the frame portion 22. That this box 44 may oscillate it is made with a pin or stud 45, which is arranged in a bearing 46 in said frame portion 22 and is held in its operative position by a washer 47 and a nut 48 on a screw-threaded end portion of said pin or stud, as clearly illustrated in Fig. 10. That the said rest 41 may be held in the IOf desired angular position lhave arranged upon a pin 50 within the chambered part 51 of the box et a dog or pawl having a lever 53, by means of which the dog or pawl 52 can be made to engage with the teeth of the said barl2 or can be forced out of engagement therewith, as will be clearly evident from an inspection of Fig. 9.

Of course it will be clearly understood that some changes may be made in the various arrangements and combinations of the devices and their parts, as well as in the details of the construction thereof, without departing from the scope of my present invention. Hence I do not limit my invention to the exact arrangements and combinations of the devices and their parts as described in the foregoing specilication and as illustrated in the accompanying drawings; nor do 1 confine myself to the exact details of the constructions of the said 1 parts.

Having thus described my invention, what I claim is 1. in a rocking-chair, the combination, with a base. and a chair-body, of a suspension device for swinging said chair-body above the base, and a locking attachment for locking said chair-body in a fixed position, comprising a spring-plunger on said chair-body, said plunger being provided with an opening, a roller in said opening, a rod pivot-ally connected with said base, said rod being movably arranged upon said roller, and means for locking said plunger and rod in fixed holding engagement, substantially as and for the purposes set forth.
