The apparatus includes a feed sprocket, a spring biased shutter, a simple optical lens and a translucent screen disposed within a small window which is located opposite the viewing aperture and in close proximity with the film loop. Both the drive sprocket and the shutter of the film viewer are operated by the hand crank which car be easily manipulated by the child to controllably advance the film past the viewing aperture.

  • Patent number: 4725063
    Abstract: Disclosed is a device used to practice putting including a putting station and a remote target station. The putting station comprises a mat on which two parallel rows of posts are provided which straddle parallel strips that serve as guides for the putting head. The number of posts in each row may be the same or different. If there is an unequal number of posts, an entry way and an exit way is provided through which the club head may be moved by the golfer when swinging at the ball. The target station includes a body member having two parallel ramps, separated by a vertical wall, which lead to a collector section. One ramp serves as an entry ramp and target. The other ramp serves as an exit ramp to allow the ball to move under the force of gravity from the collector section. The collector section includes a lip which acts as a stop to prevent the ball from rolling beyond the target station if it is moving at the desired speed, but will allow the ball to roll over it if it is moving at an excessive speed.

  • Patent number: 4470411
    Abstract: A protective boot which can be removably attached to the legs of horses, that may be engaged in a variety of activities such as galloping, jumping and the like, in a position extending over the shank and contiguous fetlock joint areas, and which comprise a body portion formed of an outer layer of flexible synthetic plastic sheet material and an inner cushion layer of foamed synthetic plastic material having their confronting surfaces bonded together, the inner layer also being formed to provide a plurality of ribs separated by open-sided grooves extending longitudinally of the body and lengthwise of the horse's leg. Through-going perforations in the grooves and ridges permit evaporation of sweat. Attaching bands or straps are integrally formed with the outer layer of plastic sheet material for engagement by clamping devices, and in which these bands have strengthening fabric inserts and transverse laterally spaced apart ridges to prevent slippage in the clamping device.
