The operation of the doll is as follows. Normally, as above mentioned, the doll assumes the position shown in full lines in Fig. 2. The doll is rst cocked, that is, the body l is swung down either into or somewhat beyond a position of alignment with the legs, the last-named position being indicated in broken lines in Fig. l. Y Assuming that the body is swung downward, Fig. 1J to assume a position so that it extends downward at a small angle with respect to the horizontal (which it can be made to do if the doll is held in the hands), it is apparent that the piston 26 will have been moved very close to the head en-d 23 of the cylinder thus compressing the spring 21. During this cooking movement of the body, while the piston is moving from the lowermost position shown in Fig. 2 to the position shown in broken lines in Fig. l, the air between the piston and the head of the cylinder ows out through the vent 29 and air is drawn into the lower portion of the cylinder through the clear- However, when the piston gets beyond the vent 29 in its forward travel, its force tends to compress the air caught between the piston and the head end of the cylinder, eX- ceptthat a leakage escape is provided by the groove 29a and through the vent 29 and opening 25a, thus permitting thev piston to travel to a position very'close to the head end of the cylinder. However, although the groove 29a has been defined as a groove, it is in fact of very small, almost minute, cross-section, and even a scratch made with a suitable tool such as an awl, on the wall ci the cylinder, will suffice as a means of air leakage past the piston. in fact, in case the interior wall of the cylinder is not machined to a good degree of smoothness, suicient leakage will be provided by the imperfections of the cylinder surface in that air may pass between the piston and theV depressions between the raised portions of the unsmoothed surface.

Thus, immediately after "cocking the doll as aforesaid, when it is placed on its` back on a table 'or the like, thedegree of compression remaining in the head of the cylinder will force the piston back a very small distance, sucient to align the body and legs substantially as shown in full lines in Fig. 1. After being thus placed on its back, the doll will be moved imperceptibly by movement A to the left (Fig. 1) of the piston consequent to the very small rate of iiow of air past the piston through the groove 29a and out into the lower end of the cylinder or through the vent 29, thus very slowly relieving the compression in the head end of the cylinder. Likewise, the force of the compressed. spring 2l is at work, but as it tends to push the piston back its action is resisted bythe tendency to create a vacuum at the head of the cylinder and the only air inlet to relieve this vacuum is the groove 29a. As a result of these conditions, the piston will at rst move so slowly to the left that its effect on the body IG, that is, pivoting the body iii upward, is actually imperceptible during this time. However, as soon as the piston has been moved a suihcient distance to the left to begin to clear, and then to clear, the Vent 29 sol that air can rush through the vent into the head end of the cylinder, the full force of the spring will become effective in moving the piston rapidly to the left so that the body l will rapidly swing into the sitting position.

The amount of time after laying the doll fiat 4 on a surface, as shown in Fig, l, intervening before the doll will visibly pivot into sitting position, is controllable during manufacture in that the vent 29 may be positioned as shown, or more or less distant from the head of the cylinder, as is obvious. Y

The weighted legs of course prevent the legs from rising and cause the body, instead, to pivot about the axis of connection between the legs and body. Since, during pivoting of the body, the lower end of the body, shown at 33, swings throughl an arc, to facilitate operation of the doll the lower end 33 of the body is circularly curved with the center of curvature lying in the axis of the yoke arms IS. rIhe rear portion 34 of the lower end 33 of the body is likewise curved along a continuation of the arc of the bottom 33 to provide clearance for the crank 2| and sleeve 22.

Provision of the two halves Illa and lllb joined along the line 32, permits of easy assembling of the complete doll. Provision of the at surfaces i3 on the legs Il and the at surfaces i6 on the body extension l5, permits of the relative rotary movement between the body and the legs with a minimum of resistance and friction.
