Abstract: The disclosure describes a device for transferring a ball, skein or package from a winding mandrel to a freely projecting carrier arm mounted on a conveyor belt. This purpose is served by a wedge member, onto which the wound ball is moved by a gripping device and which subsequently moves with the ball towards the carrier arm. The wedge member and carrier arm both have a cross sectional profile which enables the wedge member to be displaced lengthwise of the carrier arm so as to pass over and beyond it and so the ball is pushed onto and remains on the carrier arm. In this way, the ball is exactly positioned and an arrow label may be inserted into the center hole of the ball with the aid of the carrier arm. Once the label has been inserted the labelled ball is withdrawn from the carrier arm.

Abstract: A loader/unloader assembly for use with a vertical tiltable platform stores conveyor having a horizontal load position, a vertical stowed position and an intermediate inclined unload position. The load platform contains guide pins cooperating with a race track-shaped guide groove for selectably positioning the load platform in the three positions. When the load platform is in the unload position, a spring biased camming plate prevents displacement of one of the guide pins except upon application of a predetermined downward force to the load platform which serves to move the camming plate to an inhibit position and activate a switch to disconnect power from the conveyor system and stop conveyor movement. The force necessary to trigger the inhibit action may be selectably adjusted on the loader/unloader assembly.

Abstract: The material-receiving end, or tail piece assembly of an endless belt conveyor in a mining installation is constructed so as to be self-cleaning in the sense that the normal spillage of the mined material such as coal on to the mine floor adjacent the tail piece is reduced or avoided, thereby eliminating the need to remove spilled material and eliminating the safety hazard inherent in such removal. This object is accomplished by automatically collecting, within the tail piece assembly, the material which normally spills off the upper belt run and conveying the collected material back to the upper run. In the preferred construction the tail piece assembly includes an enclosure surrounding the tail roller of the conveyor, water sprays for forming a slurry of the spilled material and a slurry pump for pumping the slurry to the upper belt run.
