A pair of arm members are attached to the shaft, one being rigidly attached and the other being rotatably attached with respect thereto. Springs are provided for biasing the arm members to a first position for locking the actuating device against an abutment surface connected to a frame member. A cam structure associated with the actuating device is provided for rotating the shaft to thereby unlock one of the arm members under certain circumstances. A projection of a coin registering mechanism is provided to cause unlocking of one or both of the arm members when a predetermined amount of money is registered on the coin registering mechanism.

Abstract: A volumetric accumulating device for use in combination with a conveyor system. The device is connected to the underside of the conveyor system and includes a housing having two sidewalls with two end walls positioned therebetween. One of the end walls includes a portion which converges downwardly towards a lower end. A discharge opening is formed adjacent to the lower end of the housing. A metering device for selectively controlling the amount of material received within the housing includes an arcuately shaped plate pivotally attached adjacent to the top of the housing and is positioned transversely with respect to the sidewalls. The edges of the plate are complementary to the shape of the sidewalls which permit them to remain adjacent to the sidewalls during pivotal movement of the plate between a vertically oriented position adjacent to the end wall having the converging downwardly portion, and a horizontally oriented position.

Abstract: A global time system having a first disc divided into twenty-four equal sections, each section being formed by lines extending radially from the center of the first disc. Each line forming the sections representing a line of longitude. Circles are concentrically disposed about the center of the disc and extend outward to the edge of the disc. The circles, representing lines of latitude, cross over each of the twenty-four lines of longitude to form geographic spaces between the lines of longitude and latitude. A time disc is rotatably mounted to the center of the first disc and has twenty-four lines equally spaced from each other on the outside edge. Reference symbols are positioned on the first disc and adjacent to the outside edge of the time disc, with the reference symbol in each of the twenty-four sections. Identification symbols representing a specific geographic location are disposed within the respective geographic space having the proper longitude and latitude of the location.

Abstract: A base having a lower, ground-engageable portion and an upper portion. An indicator mechanism is formed by first and second perpendicularly intersecting planar members. Each of the outer planar surfaces of the planar members includes a distinctive color, and each color is different from the others. The first planar member defines a plane oblique to the ground while the second planar member defines a plane normal to the ground. The indicator mechanism is attached to the upper portion of the base. When the golfer assumes a golfing stance adjacent the base and gazes at the indicator mechanism, the upper edges of the planar members form an inverted T-shape, the side surfaces of the planar members not being visible.

Abstract: A sleeve having front and rear halves. The front sleeve half has an aperture formed therethrough and a spout affixed thereto over the aperture. An auger brace is attached between the wall of a grain bin and a vertical truck conveyor.
