Abstract
Abstract A slip clutch with a signal for revealing when the clutch is slipping, and including a rotatable driving member and a rotatable driven member rotationally engaged with the driving member, and with the two members being rotatable relative to each other. A projection is carried on each of the two members, such that they hit against each other when the clutch is slipping, and one of the members is of a metallic material and cylindrically shaped so that it rings like a bell when its projection is being hit. A sphere is carried by the other member and is under the influence of centrifugal force to extend radially outwardly and hit the other member when the clutch is slipping and thereby create the audible signal.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
212 words
A slip clutch with a signal for revealing when the clutch is slipping, comprising a rotatable driving member, a rotatable driVen member rotationally engaged with said driving member until a pre-determined driving force therebetween is reached and whereupon said driving member rotates relative to said driven member, each of said members having an outer surface and with said surfaces being faced toward each other and spaced from each other, a projection on said surface of one of said members and extending toward the other of said surfaces for traversing a path of rotation in the space between said surfaces and upon rotation of said one member, the other of said members having a pocket extending into its said surface and having a limiting means in the depth of said pocket, a projection member movably disposed in said pocket and being movable therein against said limiting means and being supported therein to extend partly from said pocket and into said path of rotation of said projection on said one member for striking said projection when said members are rotating relative to each other, and with said projection member being related to said pocket to be restrained by said pocket for retracting from said projection upon striking said projection in creating the audible signal.
Claim 2
Dependent Claim
212 words
A slip clutch with a signal for revealing when the clutch is slipping, comprising a rotatable driving member, a rotatable driVen member rotationally engaged with said driving member until a pre-determined driving force therebetween is reached and whereupon said driving member rotates relative to said driven member, each of said members having an outer surface and with said surfaces being faced toward each other and spaced from each other, a projection on said surface of one of said members and extending toward the other of said surfaces for traversing a path of rotation in the space between said surfaces and upon rotation of said one member, the other of said members having a pocket extending into its said surface and having a limiting means in the depth of said pocket, a projection member movably disposed in said pocket and being movable therein against said limiting means and being supported therein to extend partly from said pocket and into said path of rotation of said projection on said one member for striking said projection when said members are rotating relative to each other, and with said projection member being related to said pocket to be restrained by said pocket for retracting from said projection upon striking said projection in creating the audible signal.
Claim 3
Dependent Claim
25 words
The slip clutch as claimed in claim 1, and wherein said limiting means is a spring disposed in said pocket and beneath said projection member.
Claim 4
Dependent Claim
17 words
The slip clutch as claimed in claim 1, and wherein said projection member is spherically shaped member.
Claim 5
Dependent Claim
26 words
The slip clutch as claimed in claim 3, and wherein said limiting means is a spring disposed in said pocket and beneath said spherically shaped member.
Claim 6
Dependent Claim
40 words
The slip clutch as claimed in claim 1, wherein said one of said members includes a cylindrically shaped portion and is of a metallic characteristic to produce a sound of a ringing bell when being struck by said projection member.
Claim 7
Dependent Claim
45 words
The slip clutch as claimed in claim 5, and wherein said projection on said one of said members is an indent in said cylindrically shaped portion, and said projection member on said other of said members is a spherically shaped member of a metallic characteristic.
Claim 8
Dependent Claim
159 words
A slip clutch with a signal for revealing when the clutch is slipping, comprising a rotatable driving member, a rotatable driven member rotationally engaged with said driving member until a pre-determined driving force therebetween is reached and whereupon said driving member rotates relative to said driven member, a projection on each of said members and disposed in the rotational paths of each other and being relatively movable toward and away from each other to hit each other during the relative rotation and to thereby create an audible signal, said projections being of metallic characteristic to produce a bell-ringing sound when creating the signal, one of said members being partly bell-shaped and encircles a portion of the other of said members, said projection on the encircled one of said members being a sphere movably supported on the latter said member to be under the influence of centrifugal force for radially outward movement to hit the other one of said projections.
Claim 9
Dependent Claim
159 words
A slip clutch with a signal for revealing when the clutch is slipping, comprising a rotatable driving member, a rotatable driven member rotationally engaged with said driving member until a pre-determined driving force therebetween is reached and whereupon said driving member rotates relative to said driven member, a projection on each of said members and disposed in the rotational paths of each other and being relatively movable toward and away from each other to hit each other during the relative rotation and to thereby create an audible signal, said projections being of metallic characteristic to produce a bell-ringing sound when creating the signal, one of said members being partly bell-shaped and encircles a portion of the other of said members, said projection on the encircled one of said members being a sphere movably supported on the latter said member to be under the influence of centrifugal force for radially outward movement to hit the other one of said projections.
Claim 10
Dependent Claim
26 words
The slip clutch as claimed in claim 7, wherein said projection on said one of said members is an indent in the bell shaped portion thereof.
