  • Patent number: 4071364
    Abstract: A musical movement which comprises, primarily, a metal comb produced by a chemical machining process and, secondarily, a drum in the shape of a frustum of a stepped comb. The comb is advantageously provided with means whereby it can be fastened to a movement base without employing bolts or the like and the drum steps advantageously have projections, for co-operation with the comb teeth, that do not extend further radially than do the immediately neighboring drum steps of larger size.

  • Patent number: 4057612
    Abstract: A method of producing an article which incorporates an insert intended to perform a function in the finished article in which method the insert is placed in a rotation mold and material is molded around said insert to envelope the insert in the material. The method is particularly, but not exclusively, concerned with the production of prehensile hands for dolls and other primate figures in which an insert that includes a spring is enveloped in a synthetic plastics material, such as polyvinyl chloride, by a rotation molding process to produce a hand which will tend to grip an item placed between at least one finger and the thumb thereof.

  • Patent number: 3955311
    Abstract: A push button in the upper side of the torso of a toy figure is hand operated. By pushing the button this motion is transmitted to a lever which is rotated upwardly. The upward motion of the lever is translated into a rotary motion of a ball joint which is connected to an upper arm of the toy figure. By movement of the push button the arm of the toy figure is thus moved from a preselected position into an upward position. A connection between the upper and lower arm portions permits the lower arm portion to continue movement after the upper arm portion has stopped thereby imparting a life-like movement to the figure.
