3 Claims.

This invention relates to rockers especially adapted for children to afford amusement with a maximum amount of safety and comfort, and has for the primary object the provision of a device which will be durable and cheap to manufacture and will be easy to operate so that com-'- paratively young or small children may successfully use the device.

With these and other objects in view this invention consists in certain novel features of constructioncombination and arrangement of parts to be hereinafter more fully described and claimed.

For a complete understanding of my invention, I

reference is to be had to the following description and accompanying drawing, in which Figure 1 is a top plan view, partly in section, illustrating a rocker constructed'in accordance with my invention.

Figure 2 is a vertical sectional View illustrating the same.

Figure 3 is a fragmentary sectional view taken on the line 33 of Figure 2.

Figure 4 is a fragmentary transverse sectional view taken on the line 4-4 of Figure 2.

Figure 5 is a fragmentary sectional view showing the connection between the spring means and the rocker structure.

Referring in detail to the drawing, the numeral I indicates an elongated frame, the side members' of which form tracks 2 on which rocker elements .3 operate. The rocker elements 3 are provided with arcuately curved faces 4 so that said rocker elements on the tracks 2 may rock backward and forward. The rocker elements are joined by a seat structure 5 consisting of aseat 6, back! and feet and toe boards 8 and 9, respectively. The rocker elements slightly in advance of the seat 6 are cut away to form side entrances I 0 to permit a child to readily enter and exit from the device. Supporting members I I are secured to the rocker elements in advance of the entrances Ill and extend from the floor board 8 upwardly beyond the upper edges of the rocker elements andin advance of the seat 6 and are connected by a hand rail l2 which is posi tioned to be easily grasped by a child when sitting upon the seat 6. l

- A substantially, U-shaped frame I3 is positioned horizontally and is secured to the tracks 2 with the bight portion of said frame traversing the space between the tracks and has adjustably connected thereto an anchoring element I4 to which one end of a coil spring I5 is secured, The other end of the spring I5 is connected to a plate I5 and the latter is pivoted to a hanger I1. The hanger is provided with a bifurcated portion between which is pivoted the plate IB and one end of a connecting link I8, A shaft I9 is connected to the tracks and extends through the arm por- 5 tions of the frame I3 and has journaled thereon the hanger l I. A U-shaped support'2ll is journaled on the shaft I9 with its arm portions 2| extending upwardly and carrying a shaft 22 on which is journaled the upper end of the link I8. 10 The arm portions 2i of the frame 20 are capable of a rocking motion on the shaft I9 by the rocking movements of the rockerelements 3. The shaft 22 is connected to a sub-frame 23 mounted to the seat structure 5, as shown in 5 Figure 4, by connecting members 24 each of which consists of a substantially triangularshaped element as suggested in Figure 4. The connecting members 24 are journaled to the shaft 22 and pivoted to the subframe 23. This tri- 20 angular-shaped element provides strength to each of the members 24-and prevents shifting of the connecting member or link I8 on the shaft 22.

The normal position of the rocker elements is 25 as shown in Figure 2 with the spring I5 under a slight tension. A child occupying the seat 6 leans first'forwardly and then backwardly to start the rocking motion of the rocking elements on the track and this rocking motion is aided by the 30 spring l5. It is to be understood that the spring I5 receives its greatest tensioning when the rock- .er elements reach approximately the limit of their rocking motion in either direction so that when the child shifts its weight the spring acts to aid 35 in moving the rocking elements in a reverse direction. The arrangement of the spring and its connection with the rocking elements also prevents the latter from rocking in either direction to an extent that it would be dangerous to the child occupying the seat.

The rocking motion of the rockers on the track cause a'forward and rearward swinging movement of the shaft 22 due tothe latter being connected to the subframe 23 by the connecting members 24. The shaft 22 being connected to the hanger I1 by the link l8 will cause said hanger to swing upwardly and downwardly on the shaft I9 during said swinging movement of the shaft 50 22. The upward and downward movement of the hanger I'I increases the tension of the spring 15. Thus it will be seen that the spring acts to aid the rocking movements of the rockers on the I track. 7 55 Having described the invention, I claim:

1. A rocker comprising a rocker structure, a support for supporting said rocker structure, a pivotal frame pivoted to the support, spring means connected to the support, a member pivoted to the support and pivotally connected to said spring means, means connecting the rocker structure to the pivotal frame, and means connecting the pivotal frame to said member.

2. A rocker comprising a rocker structure, a support for supporting said rocker structure, a shaft secured to the support, a movable frame journaled to the shaft, means connecting the movable frame to the rocker structure, a springthe shaft and pivotally connected to the spring, and means connecting said member to the movable frame.

3. A rocker comprising a rocker structure, a support for supporting said rocker structure, a shaft secured to the support, a movable frame journaled to the shaft, connecting elements journaled to the movable frame and pivoted to therocker structure, a spring adjustably connected to the support, a platelike member journaled to the shaft and pivotally connected to the spring, and a link pivotally connected to the movable frame'and to the plate-like member.
