Abstract
Abstract The invention disclosed is a coupling of the gear type which is constructed in such a manner that one of its hubs can be moved from a connected position where its teeth engage the teeth on a sleeve, to a position where its teeth are disengaged from the sleeve teeth. Particular shaped locking plungers which engage particularly shaped recesses in the sleeve are provided to hold the hub either in locked or unlocked position. The particular shape of the plungers and grooves resist movement of the sleeve.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
287 words
A coupling comprising a sleeve a first hub and a second hub, said sleeve having a first end and a second end, first internal teeth on said first end, said first hub having external teeth slidably meshing with said first internal teeth, means on said second end of said sleeve for engaging said second hub, at least a pair of axially spaced notches in each of said internal teeth, said notches being disposed in a first circular path and a second circular path spaced axially from said first circular path, said external teeth on said first hub meshing with said internal teeth on said sleeve and axially slidable thereon from a first position to a second position, an elongated detent means in said first hub, spring means urging said detent means outwardly, said detent means having inclined sides sloping radially outwardly and toward each other at an angle to the central axis of the detent substantially equal to the angle of the edges of said notches, said sloping sides substantially coextensive with substantially the entire sides of said notches, the outer end of said detent means being received in said notches in said first circular path, when said sleeve is connected to said second hub, said sleeve being axially slidable to move said first sleeve teeth out of engagement with said first hub teeth and to move said detent means out of said first notches and into said second notches, said means of said second end of said sleeve being disengaged from said second hub when said detent means are in engagement with said second notches and a flattened portion on said detent means providing an air passage from below the detent to adjacent the sloping sides.
Claim 2
Dependent Claim
287 words
A coupling comprising a sleeve a first hub and a second hub, said sleeve having a first end and a second end, first internal teeth on said first end, said first hub having external teeth slidably meshing with said first internal teeth, means on said second end of said sleeve for engaging said second hub, at least a pair of axially spaced notches in each of said internal teeth, said notches being disposed in a first circular path and a second circular path spaced axially from said first circular path, said external teeth on said first hub meshing with said internal teeth on said sleeve and axially slidable thereon from a first position to a second position, an elongated detent means in said first hub, spring means urging said detent means outwardly, said detent means having inclined sides sloping radially outwardly and toward each other at an angle to the central axis of the detent substantially equal to the angle of the edges of said notches, said sloping sides substantially coextensive with substantially the entire sides of said notches, the outer end of said detent means being received in said notches in said first circular path, when said sleeve is connected to said second hub, said sleeve being axially slidable to move said first sleeve teeth out of engagement with said first hub teeth and to move said detent means out of said first notches and into said second notches, said means of said second end of said sleeve being disengaged from said second hub when said detent means are in engagement with said second notches and a flattened portion on said detent means providing an air passage from below the detent to adjacent the sloping sides.
Claim 3
Dependent Claim
221 words
A coupling comprising a sleeve having internal teeth, a hub having external spaced teeth supported in said sleeve, said external teeth engaging said internal teeth, means on said hub to connect it to a first drive member, means on said sleeve to connect it to a second drive member, said means on one of said sleeve and hub to connect them to a drive member being disconnectable when said hub and said sleeve are slid relative to each other from first position to a second position, engaging means in the spaces between said hub teeth engaging means on said sleeve teeth for holding said teeth in said first position or in said second position, said engaging means between said hub teeth comprising spring loaded means having sides sloping outwardly and toward each other, said means on said sleeve teeth comprising first and second notches in said sleeve teeth for receiving said detent means, said detent means being elongated generally cylindrical with frustoconical ends and engaging said notches, said notches being complimentary in shape to said frustoconical ends, said sloping sides being substantially coextensive with substantially the entire sides of said notches, said first notches being spaced from said second notches and a flattened portion on said detent means providing an air passage from below the detent to adjacent the frustoconical ends.
Claim 4
Dependent Claim
221 words
A coupling comprising a sleeve having internal teeth, a hub having external spaced teeth supported in said sleeve, said external teeth engaging said internal teeth, means on said hub to connect it to a first drive member, means on said sleeve to connect it to a second drive member, said means on one of said sleeve and hub to connect them to a drive member being disconnectable when said hub and said sleeve are slid relative to each other from first position to a second position, engaging means in the spaces between said hub teeth engaging means on said sleeve teeth for holding said teeth in said first position or in said second position, said engaging means between said hub teeth comprising spring loaded means having sides sloping outwardly and toward each other, said means on said sleeve teeth comprising first and second notches in said sleeve teeth for receiving said detent means, said detent means being elongated generally cylindrical with frustoconical ends and engaging said notches, said notches being complimentary in shape to said frustoconical ends, said sloping sides being substantially coextensive with substantially the entire sides of said notches, said first notches being spaced from said second notches and a flattened portion on said detent means providing an air passage from below the detent to adjacent the frustoconical ends.
Claim 5
Dependent Claim
56 words
The coupling recited in claim 2 wherein said detents have a cylindrical intermediate part with a first end and a second end, said first end being said frustoconical, said second end being reduced in size, said detents being received in circumferentially spaced bores in said hub, compression springs in said bores surrounding said reduced size ends.
