tion of" the slots in the ends of bar 6 is I The improvements. set forth herein relate specifically to the figurehead described n United States Patent Number 1,511,044,.1ssued October 71., 1924, to Roy W. Adams. This certain type of figurehead is a representation of a winged figure and has movable. wings. I

In the accompanying drawings: I

Figures 1, 2, and 3 show top, front and side views respectively of a mechanism that tilts the wings of the figurehead in such a way that the upper and under surfaces of the wings would receive the pressure of a current of air alternately, should the current of air be coming from the direction in which the figurehead is pointing. Receiving the presure of a current of air on the upper and under surfaces alternately causes the wings to move up and down, or flap, in imitation of the efforts of a flying creature. Figure 2 shows the front view of the mechanism in position within the hollow body of the figv urehead, shown in section, and the front elevation of the wing joints, wing arms and part of the wings.

In Figures 1, 2, and 3, 1 is a plate having a slot- 2 and a closed groove 3. 21 is another plate having a slot to match the slot in plate 1. Plates 1 and 21 areheld together by screws with spacers 13 between them. 6 is a bar extending through the slots in plates 1 and 21. 4 is a crank, located between plates 1 and 21, connected to bar 6, and having a. pin 5 which is slidable in groove 3. 15 is a spring held in position by a clip 18 and two spacers or washers 16 and 17 which are fastened to one of the plates. The ends of spring 15 are curled to form an eye at each end as shown in Figures 1 and 3. 26 is a pin which extendsthrough an arm of crank 4. Pin 26 is so positioned that it may engage the eye in either end of spring 15 causing crank 4 to become operatively connected to either end of spring 15. As crank 4 is driven up and down, by the wingarms acting through bar 6, spring 15 is brought under torsion by the arm of crank 4 acting alternately on its two ends. The action of spring 15 causes the pin 5to follow around groove 3 as crank 4 is moved up and down. As pin 5 follows around groove 3 crank 4 imparts a turning movement to bar 6. In each end of bar 6 is a slot by which each end is operatively connected through a yoke to one of the wing arms 14. As bar 6 is turned the inclinachanged and this change of inclination is imparted to: the wings 8, through the wing arms 14..

The action described herein is. identical with the action dcscribedin the specification of United States Patent Number 1,511,044, the difference in the mechanisms being: The mechanism herein described has a single crank operating between two plates instead of a single plate with. a crank on either side and: The mechanism herein described has a torsion spring acting upon an arm of the crank in place of the tension springs used in the mechanism of Patent Number 1,511,044. The torsion spring makes for a smoother and simpler acting mechanism.

In the accompanying drawings Figures 4 and 5 show a top and front view of a type of wing joint used in the figurehead. In Figures 4 and 5, 19 is a cylinder which operates in a sleeve 20; 14 is a wing support member or wing arm which extends laterally through cylinder 19 and sleeve 20. To one end of 14 is fastened the wing 8, the other end is forked with a pin 9 across the end of the fork forming a yoke. Pin9 operates in a slot in the end of bar6 as shown in Figure 3. Sleeve 20 is cut away on either side so as to permit angular motion of the of the wings requires that wing arm 14 be v able to rotate.

Figures 6 and 7 illustrate anothertype of wing joint. In Figures 6 and 7 wing arm 14 extends through a spherical member or ball 22 "which is supported between two members 23 and 24, which in turn are set in the body 12. Members 23 and 24 are so shaped as to form a socket-like support for ball 22 as shown in Figure 7. Wing arm 14 may be free to rotate in ball 22, or the two members may be made integral since ball 22 may rotate in its socket. Ball 22 operating in a socket makes it possible for wing arm 14 to execute an angular movement as well as rotate.

I claim:

1. A representation of a Winged figure i having a hollow body, movable Wings and support members therefor rotatably mounted in said body, plates located Within said body, each of said plates having a slot and either of said plates having a closed groove, a bar extending through said slots and having its ends operatively connected to said support members, a crank connected to said bar, said crank having a pin slidable in said groove, a double acting spring operatively connected to said crank in such a Way-as to cause said pin to follow around said groove in response to Wind pressure upon said Wings.

2. In a device of the kind described the combination of a member having a cylindrical shaped cavity, a cylindrical member operating Within said cavity, athird'memlar motion, a bar connected to one end of 25 said third member for imparting rotatory motion thereto and receiving lateral motion therefrom, and a representation of a Wing of a Winged creature mounted on the other end of said third member.

ROY W. ADAMS.
