Abstract

Abstract Clutches controlling motion in opposite directions have actuators movable oppositely, said actuators being moved by operating linkage from a control lever which includes lost motion designed to actuate one of the actuators only in one direction of lever oscillation and the other actuator in the opposite direction of lever oscillation. In a special arrangement, the driven part is locked against movement in either direction by manipulation of the normally stationary linkage to cause both disk packs to be engaged simultaneously.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 112 words
TShe combination of a driven shaft and driving connections thereto including selectively operable cam-actuated clutches each comprising a disk pack with a pin actuator, a control member selectively movable in opposed directions for engaging respective clutches, lost motion linkage connected with said member and including a link provided with slots through which said pins project, said link having at opposed ends of said slots cam surfaces for engagement with respective pins according to the direction of movement of said link and constituting means for effecting engagement of the respective clutches and thereby causing the driven shaft to be operated from respective differing clutches according to the direction of operation of said member.
Claim 2
Dependent Claim 112 words
TShe combination of a driven shaft and driving connections thereto including selectively operable cam-actuated clutches each comprising a disk pack with a pin actuator, a control member selectively movable in opposed directions for engaging respective clutches, lost motion linkage connected with said member and including a link provided with slots through which said pins project, said link having at opposed ends of said slots cam surfaces for engagement with respective pins according to the direction of movement of said link and constituting means for effecting engagement of the respective clutches and thereby causing the driven shaft to be operated from respective differing clutches according to the direction of operation of said member.
Claim 3
Dependent Claim 46 words
A combination according to claim 1 in which each disk pack has a pressure plate and relatively rotatable and non-rotatable complementary cam disks, the pin actuator for each clutch being connected with the pressure plate thereof, and a complementary disk having means fixing it against rotation.
Claim 4
Dependent Claim 107 words
A combination according to claim 1 in which each clutch comprises a disk pack including a pressure plate and relatively rotatable and non-rotatable complementary camming disks, a pin actuator of each clutch being mounted on the relatively rotatable camming disk thereof and the said link provided with opposing pin-engaging surfaces having such surfaces spaced in excess of spaces between the pins of respective clutches, whereby the respective pin of one clutch may be in engagement with a pin-engaging cam surface while the respective pin of another clutch may have moved from the opposing surface according to the direction of relative movement between the pins and the link.
Claim 5
Dependent Claim 25 words
A combination according to claim 3 in which the link is relatively fixed and one pin engaged therewith is on a relatively non-rotatable cam disk.
Claim 6
Dependent Claim 37 words
A combination according to claim 1 in which a pin for operating one of said clutches is engaged with a link surface connected with a camming disk which is relatively rotatable for engagement of the respective clutch.
Claim 7
Dependent Claim 145 words
A combination according to claim 1, each of the clutches having an actuator comprising a pair of cam disks which are relatively rotatable, one disk of each pair being normally relatively non-rotatable and the other disk of each pair being normally connected by said lost motion linkage with said member, said linkage comprising a pair of toggle links having means pivotally connecting them with each other and with which respective normally non-rotatable disks of respective pairs have lost-motion connection, a fixed anchorage with which one of the toggle links is connected, and displacing means connected with the toggle links adjacent the means which pivotally connect them with each other, said displacing means constituting means for concurrently subjecting the normally fixed disks of both of said pairs concurrently to movement in a clutch-applying direction, whereby both clutches may be engaged simultaneously to lock the driven shaft.
