Abstract: A scarf-joint structure for the paper tube of a film dispenser is mounted in a film dispenser, which includes a frame connected with a film installation unit and an adjustment unit. The film installation unit is installed with a film roll and consists of a first positioning member and a second positioning member. The adjustment unit is formed with an operating part and a connecting part, and the operating part is connected with an adjusting member, which is threadably fixed with a screw fastener and further, an elastic member is mounted between the operating part and the connecting part. Thus, the film roll, the first positioning member and a second positioning member can be rotated synchronously, able to prevent the film roll from running idle, causing dislocation and falling off.

Abstract: A machine tool arbor for holding a rotating machine part or workpiece is fitted with an actuator member at a back or distal end of an arbor main body for tool-less chucking and unchucking of a machine part or workpiece at a front or proximate end of the arbor main body. An actuator ring or knob is mounted at the back end of the arbor main body which, when rotated in one direction, causes an pusher member (collet pusher part, hydraulic piston) to move in such a manner as to displace a chuck member (inclined collet, flex collet, expansion ring) and release the machine part or workpiece that is chucked. When rotated in the opposite direction, the actuator knob causes the actuator member to move in an opposite manner as to fix the chuck member in a position to firmly hold the machine part or workpiece to be chucked.

Abstract: A device for rotating a web material roll supported on a reel shaft having a pair of ends. The rotating device includes a female drive member coupled to one end of the reel shaft and defining an opening having a non-circular perimeter, such as a square opening. Also included is a male drive device having a rotatably powered drive shaft having an end that is congruent to the non-circular perimeter of the opening in the female drive member. The non-circular perimeter allows the reel shaft, and web material roll, to be positively rotated during unwinding. A telescoping assembly of the male drive device is capable of extending the drive shaft into the opening so as to allow co-rotation of the shaft and female member. An optional roll supporting cart may be employed to rotatably support the web material roll when aligning the male and female drive members.

Abstract: A toilet paper dispenser for providing heated toilet paper having lotion thereon. The toilet paper dispenser includes a roll of toilet paper partially saturated with a lotion. A housing has a top portion, and a bottom portion. Each of the top and bottom portions has a first side wall, a second side wall, a front edge and a back edge. The back edges are pivotally coupled together. A pair of supports support the housing on the vertical wall. Each of the supports is attached to one of the side walls of the bottom portion and each of the supports is attached to the vertical wall. A spindle is removably extended into each of the side walls of the bottom portion. The spindle extends through the roll of toilet paper. A heating element is positioned in the housing and attached to the bottom portion of the housing.

Abstract: A mounting device for easily and quickly locking a roll of material wound around an elongated core between two supporting arms of a roll supporting device is disclosed. The mounting device comprises a tubular member provided with a fastener for fastening the tubular member to one of the arms. The mounting device also comprises a shaft slidably mounted through the tubular member. The shaft has first and second ends extending outside the tubular member. The first end of the shaft is provided with a handle and the second end of the shaft is provided with an engaging member for engaging with an end of the core. The shaft is movable relative to the tubular member between a locking position wherein the engaging member is pushed against the end of the core, and an unlocking position wherein the engaging member is withdrawn from the end of the core. The mounting device further comprises a locking device operatively associated with the tubular member and the shaft for locking the shaft into the locking position.
