Abstract: A key pulley segment in a synchronized, segmentally interchanging pulley transmission system is either first or last in a pulley segment set to engage an endless member. The first or last key segment teeth to engage or disengage, respectively, are shortened or completely trimmed, and the adjacent pulley segment to the key segment is elongated such that the inward portion of the tooth profile extends toward the key segment. Shortened tooth or teeth and an elongated adjacent segment together allow for many pulley segments to be designed as key segments. Completely trimmed teeth may be engineered to create a supporting surface for the endless member on the key segment. The elongated adjacent segment may have an extending portion which slidably mates with the supporting surface of the key segment, thereby receiving radial support therefrom.

Abstract: A web of a first sheet material and a web of a second sheet material are laminated together by a process wherein the sheet materials are wound, in an interleaved relationship, upon a roller having a radially displaceable outer surface. The roller and webs and then subjected to heating and/or a low-pressure environment so as to complete the lamination. A body of adhesive material, such as a hot melt adhesive, may be interposed between the webs and the heating or low pressure environment can activate this adhesive. Further disposed are particular configurations of rollers with radially displaceable surfaces.

Abstract: A sprocket (S) for a chain driven power transmission system used on an internal combustion engine. Severe ITVH (Noise, Vibration, Harshness) characteristics associated with a chain engaging the sprocket is damped by two annular rings (R1, R2) that are loosely positioned on either side of the circumferential row of teeth. The inner diameters (ID1, ID2) of each of the annular rings (R1, R2) form cavities between the annular rings and the sprocket grooves. Pressurized viscous fluid is supplied to each cavity via channels in the hub of the sprocket to cushion the impact of each roller of the chain as it engages each row of teeth during engine operation. The pressure of the viscous fluid creates a resistive force to minimize the severe impact noise experienced by non-damped sprockets.

Abstract: The camshaft adjusting device has an inner spring retainer which mates with a rotor and an outer spring retainer which is fixed on a spring cover plate.

Abstract: A drive wheel for pulling a chain has a diameter that can be changed continuously as the drive wheel rotates. The drive wheel has a drive shaft and there are at least 2 chain-engaging means (teeth or blades) positioned around the drive shaft for engaging a chain. The wheel has a number of modules that support the chain-engaging means and permit the chain-engaging means to move slightly in a circumferential direction a distance sufficient to engage the chain. Module locks prevent such movement when the chain is engaged, but permit it when the chain is not engaged. Extenders connect the modules to the drive shaft and can change the distance between the modules and the drive shaft while the drive shaft is rotating. Extender locks prevent the extenders from changing that distance when the chain is engaged but permit such change when the chain is not engaged. A transmission can be made by connecting the drive wheel to a sprocket wheel with a chain.

Abstract: “Improvements in fodder distribution conveyors, of the type which have an endless cable or chain with a plurality of transverse dragging means and which move along a conduit, with outlets for the unloading of corresponding portions of fodder into respective conduits and the cable or chain being moved by a driving motor provided with peripheral toothing, between whose teeth the transverse dragging means engages; characterized in that the driving wheel is made up of a disk joined to a motor means and a series of replaceable, peripheral teeth; each tooth is composed of two parts with an upper longitudinal axis channel; and, preferably, each tooth is mounted in a tilting fashion and in its interior has an elastic means, and each tooth has a conical face and another flat”.

Abstract: A drive system for use in a machine has a drive wheel and a chain. A plurality of bogies each having at least one hook are pivotally connected about the drive wheel at pre-selected spaced circumferential locations. A spring member is positioned between the bogie and the drive wheel to pre-position the bogie for engagement of the pins. The pivotal movement of the bogies in combination with the spring members reduces noise and the effects of chordal action as the bogies engage the pins through rotation of the drive wheel.

The plurality of drive teeth are coupled to the drive shaft and extend outwardly from the drive shaft beyond the support surface for being received within corresponding drive teeth openings of the belt.

Abstract: A drive system, especially a belt drive for a multi-axial vehicle running gear, has a drive drum about which the belt is looped and provided with a ring with entrainers which engage teeth on the belt when there is slip between the belt and the drum. Limited rotation of the ring relative to the drum may be effected by elliptical spring elements coupling the ring and the drum or by clutches on the drum which frequently lock the ring to the drum so as to effect control engagement of the entrainers with the belt teeth and positive drive of the belt by the drum.

Abstract: A rotable sprocket assembly transmits force from a chain into rotation of a bicycle wheel. Sprocket segments having peripheral teeth are mounted on a pair of sprocket housings so that the combined periphery of the sprocket segments is substantially circular. The housings are stationary relative to each other and each is oriented in a plane which is normal to a central rotational axis. The sprocket segments are slidable relative to the housing in a radial direction so as to vary the diameter of the combined sprocket segments. Each sprocket segment is formed from a plurality of hinged subsegments, with each subsegment having a single tooth. The sprocket segments of one housing overlap the adjacent sprocket segments on the other housing so that the pairs of overlapping teeth combine to effectively form a single tooth.

Abstract: This invention comprises a machine such as a conveyor having a chain and a powered sprocket for driving the chain. The sprocket comprises a circular main plate, individual chain-contacting teeth around the periphery thereof and each tooth being pivotally connected to the main plate for rotation relative thereto and each tooth having a cam contacting surface. An individual cam-stop is also pivotally mounted on the main plate for rotation relative thereto and adjacent to each tooth and each cam-stop has two cam areas capable of selectively contacting the cam contacting surface on its adjacent tooth, and means for positioning each of said cam-stops so that a cam area thereon will rotate its adjacent tooth towards contact with the chain as the chain enters the sprocket, and so that the other cam area will enable said tooth to rotate so as to release contact with said tooth with said chain at the desired release point between the chain and sprocket.
