SU60388A1 - Device for sequential viewing of animated patterns - Google Patents

Description

Devices are known for viewing animated patterns placed on frames freely suspended by fingers in guide grooves. Usually, when changing pictures, they are only influenced by their own weight, which significantly delays viewing.

The subject of the invention is a device for viewing multiplication drawings, in which this drawback is fixed. To do this, a belt is applied in the device, thrown over the eccentric shkIy and adjacent to one side directly to the edge of the frame with a pattern. The eccentricity of the pulleys ensures, during a certain part of their turnover, an unobstructed view of the pattern and only during another part of the revolution, the fit of THEIR to the frame of the pattern and thereby the forced change of the latter.

The implementation of the device according to the invention, is provided in (Fig. 1-3).

FIG. 1 shows a side view of the machine; on fit. 2 shows on an enlarged scale the mechanism for lowering the frame with a pattern; in fig. 3- view of the machine from the observer.

The drawings fastened on plywood or from OTHER material frames a, b, c, d ... hang on the sloping sides of box 1, which has the shape of a parallelepiped (Fig. 1). Sliding down, they alternately fall into box 2, and before falling they stop for a while in front of the observer.

To speed the fall, there are leather or rubber straps 7 and S, worn on pulleys 3 and 4 (Fig. 1 and 3). Thus, from a pair of lower SHKI1OVOV 4 receiving movement from the motor 5, the belt 7 and S transmit the rotation to the upper pulleys 3 and drag the frames down.

The pulleys have a very small eccentricity so that in one half turn the pulley of the belts is pressed tightly against the edges of the frames with drawings and they are accelerated Fall into the bottom box 2; during the second half turn of the pulleys 3 w. 4 straps from the frames will be slightly set aside - this coincides with the moments of the stops of the drawings. The stoppage occurs because the frames are held up by two blades 6, held in this position by the spring 10 {FIG. 1 and 2). To release the frame, the planochka 6 is moved aside by eccentric dislocations.
