摘要： PROBLEM TO BE SOLVED: To provide a switch lubricator capable of varying a reaction force so that, even if the width of the bottom of a movable rail is small, the reaction force is either approximately constant or increases or decreases at a slow rate with respect to the displacement of a point of application where an applied force works at the time of rail change. SOLUTION: The switch lubricator includes a microdisplacement constant pressure mechanism for varying the reaction force at the point of application so that it is either approximately constant or increases or decreases at a slow rate with respect to the displacement of the point of application. A movable rail rolling support mechanism has a plurality of rollers 14 and 15 built in for causing rolling of a tongue rail T when the tongue rail T is changed. When displaced vertically by the operation of the constant pressure mechanism, the plurality of rollers 14 and 15 move vertically at the same height.

摘要： PROBLEM TO BE SOLVED: To more practically automize and to accelerate work spreading by providing the method including a first process of throwing a work in a container and rotating the container to give rotation to the work, and a second process of dropping the rotating work in the air outside the container to spread the work with centrifugal force. SOLUTION: A work is thrown in a rotating container 10 through an acceptor 18 of an upper end opening to give rotation to the work. At this time, the thrown work rotates in the state of being positioned in a work storing part 13 by its dead load. As the work storing part 13 is gradually throttled to be an inverted pyramid-like, the work is rotated while being automatically guided to the central part near the center of rotation of the work storing part 13. When the work is rotated at a required number of rotation, an electric current is applied to the respective electromagnets 36 simultaneously to open movable blades 31 at the same time, so that the work is dropped from the storing part 13 by its dead load to be dropped in the air. As the dropped work is rotated, the centrifugal force acts on the work itself so that the work drops while spreading.

摘要： PURPOSE:To eliminate the need of moving a foot, and also, to decrease such danger as a show and the cuffs of trousers twine round a brush by providing a shoe insertion opening part, and the brush rotated by a motor on the front part of a main body, and the upper part and the left and the right, respectively, allowing a put shoe to execute automatically execute a reciprocating motion forward and backward and executing automatically its polishing operation. CONSTITUTION:The upper brush 1 is rotated by a belt 2 and motor 5 power, and side part brushes 4a, 4b are rotated by belts 5a. 5b and motors 6a, 6b power, brought into contact with solid wax 7a, 7b and 7c of shoe polish, and come into contact with the upper part and the side part of a shoe 9 on a shoe putting base 8. The shoe putting base 8 is rotated in the forward/backward directions by using a motor 14 as power by winding steel belts 13a, 13b round a drum 15 in the reverse direction by four pieces of guide wheels 11 on a rail 10. According to said constitution, since the shoe putting base 8 is moved forward and backward automatically, labor for moving a foot can be reduced, and there is scarcely such danger as a foot is inserted excessively into the inside of the device, and also, in an initial. position of the shoe 9 on the shoe putting base 8, the shoe 9 can be inserted without coming into contact with the brush by leaving a space of the side part brushes 4a, 4b, therefore, such danger as the cuffs of trousers, etc., twine round the brush decreases.
