MECHANICAL TOY.

Specification of Letters Patent.

Patented May 3, 1921.

Application filed October 14, 1920. Serial No. 416,926.

To (all 107mm it may concern:

Be it known tha l, Gnonon l-lAznL'roN, a

-which the movement of a weight serves to store energy in a part of the toy and to rotate the ib, which energy, when the weight has been moved to the required position and discennectech causes the return of the parts of the toy to the initial position.

According to this invention the toy crane or the like consists essentially in the combination of a suitable base or support, a jib or like projecting part rotatably mounted with respect to the base, a cord or other suspension member passing over the head of t u" jib and taken to a winding drum fixed with respect to the base or support and a spring so arranged between the jib or the like and the base or support, that the low ring of a weight when connected to the free d of the suspension member, charges the and revolves the jib in one direction freely about the base, while disconnection of weight from the suspension member L ftcr the weight has fallen through the desired distance, allows the charged spring to return the movin parts of the crane to their initial positions.

' invention is illustrated in the accom- 'i panying d 'awing in which Figure 1 is a side elevation par in section and Fig. 2 is a plan view (if a toy crane.

a is the base of the crane to which is fixed a vertical shaft Z), carrying at its upper end a drum 0. The shaft 6 and drum 0 do not rotate. Mounted upon the base. a is the housing (Z which has suitable apertures to allow it to rotate around the fixed shaft Z). The housing contains on one side thereof a. counter balance weight d and to the other ide is fined the jib e. A stay connects the jib c to the housing (Z and this stay is bent down insid the housing and is formed with a projection 6 A light coiled spring f surrounding the shaft 2) is fixed at one end to the projection e and at its other end to the shaft 5. In the drawing it is shown passing into an aperture 5 in the shaft Z).

The ib e is provided with suitable guides such as the pulleys e e. To the drum 0 is fixed one end of the cord g. This cord is coiled several times around the drum 0 and is then passed under the pulley e and over the pulley c.

As shown in the drawings the cord 9 is connected to a self releasing hook it which is pivotally suspended by the link k and has a laterally projecting weight h A weight in the form of bucket i is suspended by the hook 71v and puts the cord g in tension. As the cord 9' is pulling always tangentially from the periphery of the drum 0 and laterally with respect to the shaft 5 around which the jib e rotates the effect is that the jib e and housing d rotate upon the shaft 6, the cord 9 is unwound from the fixed drum 0 and the outer end of the cord 9 lowers the weight 2'. The rotation of the housing (5 charges the spring by winding it more tightly around the shaft 6.

lVhen the weight 2' reaches the surface upon which the base is standing, the weight 7L: rocks the hook on the link 70 and the hook is released. The spring then unwinds and rotates the housing (Z and jib e in the opposite direction to that in which they were moved by the action of the weight 2'. During this reverse rotation the cord 9 or other flexible connection is again wound around the drum 0.

What I claim as my invention is l. A mechanical toy having in combination a base, a vertical rod fixed with relation to the base, a drum concentric with the said rod and fixed with relation to said base, a housing rotatably mounted on said rod, a housing, guides carried by the said projection, a coiled spring fastened at one end to the said rod and at the other end to the housing and a flexible suspension member fastened at one end to said drum, wound around the drum, passing through the guides on the lateral projection and adapted to carry a weight.

2. A mechanical toy having in combination, a base, a vertical rod fixed with relation to the base, a drum fixed on said rod, a housing rotatably mounted on said rod, a lateral projection carried by said housing, guides carried by the said projection, a coiled spring fastened at one end to the said rod and at the other end to the housing and a flexible suspension member fastened at one end to said drum, wound around the lateral projection carried by said drum, passing through the guides on the lateral projection and adapted to carry a weight.

3. A mechanical toy having in combination a base, a vertical rod fixed with rela tion to the base, a drum concentric with the said rod and fixed with relation to said base, a housing rotatably mounted on said rod, a lateral projection carried by said housing, guides carried by the said projection, a coiled spring fastened at one end to the said rod and at the other end to the housing, a flexible suspension member fastened at one end to said drum, wound around the drum, passing through the guides on the lateral projection, a hook carried by the flexible suspension member, a weight carried by said hook, and a weight forming part of said hook to rock this latter and detach it from the first mentioned weight when the descent of this latter is arrested.

4-. A mechanical toy having in combina tion a base, a vertical rod fixed with relation to the base, a drum concentric with said rod and fixed with relation to the base, a housing rotatably mounted on said rod, a lateral projection carried by said housing, pulleys carried by said projection, a coiled spring fastened at one endvto the said rod and at the other end to the housing, a flexible suspension member fastened at one end to said drum, wound around said drum and guided by the pulleys on the said lateral projection and means attached to the flexible suspension member for carrying a Weight.

In witness whereof I have hereunto set my hand in presence of two witnesses.

GEORGE HAZELTQN.
