| Abstract:
Our invention relates to improvements in clutches, and particularly to clutches of the friction type, the object of our invention being to provide a clutch in which the power which drives the parts can be utilized to throw the clutch members into engagement with each other and also to provide means by which only the minimum amount of movement of the parts is required to engage and disengage said clutch members.
Claims:
1. In a clutch, a driving member, a stud connected therewith, a loose screw-threaded sleeve mounted on said stud, and a driven member having a screw-threaded hub mounted on said sleeve, said driven member having a driving connection with said driving member, a driving connection between said stud and sleeve, and means for connecting and disconnecting said sleeve with said stud, substantially as specified.
2. In a clutch, a driving member, a stud connected with said member, a loose screw-threaded sleeve on said stud, a driven member having a frictional driving-surface to engage with said driving member and screw-threaded on said sleeve, a wheel connected with said sleeve and having a limited longitudinal movement with reference thereto, and means for connecting and disconnecting said wheel with said stud, for the purpose specified.
3. In a clutch, a driving member, a stud connected with said member, a loose screw threaded sleeve on said stud, a driven member screw threaded on said sleeve and having a driving connection with said driving member, a wheel splined to said sleeve and capable of a limited longitudinal movement with reference thereto, engaging clutches or teeth on the hub of said wheel, and; a collar secured to said stud also having engaging clutches or teeth to engage with the clutches or teeth of said wheel when said wheel is moved to engaging position, for the purpose specified.
at. In a clutch, a clutch member, a spider connecting said clutch member to the driving mechanism, a pulley having a driving connection with said clutch member, a stud connected to said clutch member and adapted to be revolved thereby, a sleeve on said stud having a screw-threaded connection to said pulley to adjust same to and from engaging position with said clutch member, a driving connection between said stud and sleeve, and means for connecting and disconnecting said stud and sleeve, substantially as specified.
5. In a clutch, a driving member and a driven member, devices for moving one of said members to and from engaging position with the other, a spring-pressed pin on said devices adapted to engage with said movable member to stop the same at a predetermined distance in its travel from disengaging position, for the purpose specified.
6. In a clutch, a driving mechanism, a friction-pulley to engage with said driving mechanism, devices for adjusting said pulley with reference to said driving mechanism, a wheel connected with said devices, said wheel having means for limiting the movement of said pulley to regulate the distance which said pulley can be moved from engaging position with said driving mechanism, for the purpose specified.
7. In a clutch, a driving member, a driven member to engage with said driving member, said driven member being mounted upon a screw-threaded sleeve, a device for turning said sleeve to move said driven member to and from engaging position with said driving member, engaging devices between said driven member and said sleeve-operating device to & arrest said parts when the driven member has moved a predetermined distance from engaging position with said driving member, and means for adjusting the said engaging devices to regulate this distance, for the purpose specified.
8. In a clutch, a driving member and a driven member, one of said members being movable with reference to the other for the purpose of throwing the parts into and out of engagement with each other, devices for operating said movable member, a spring-pressed pin on said devices, and a groove in said movable member to engage said pin, for the purpose specified.
9. In a clutch, a driving member, a driven member to engage with said driving member, a screw-threaded sleeve to receive the hub of said driven member, a wheel connected to said sleeve for operating the same, a spring-pressed pin in said wheel, and a groove in said hub to receive said pin when said sleeve is turned in a direction to move said driven member from disengaging position, for the purpose specified.
10. In a clutch, a driving member and a driven member, a stud connected to the driving member, a loose sleeve on said stud screw threaded for a portion of its length, said driven member being provided with a screw-threaded hub mounted on the screw-threaded portion of said sleeve, a wheel splined to said sleeve and capable of a limited longitudinal movement thereon, clutch faces or teeth on said wheel, a clutch-collar secured to said stud, means for engaging and disengaging the said wheel with said collar, a spring-pressed pin on said wheel, a groove in said hub to receive said pin, and means for adjusting the position of said pin on said hub with reference to said groove, substantially as and for the purpose specified.
