Abstract
Abstract An apparatus to control oscillation of a grapple device on a transporting vehicle includes a pin disposed through the bore of a housing, and a retaining member associated with the pin and secured from rotation relative to one of the pin and housing. The one of the pin and housing member which is not secured from rotation relative to the retaining member, and the retaining member, together define a cooperating seatable protrusion and recess, of arcuate cross-section. Resilient means are included to urge the retaining member so as to seat the protrusion in the recess. Also included are means for limiting longitudinal movement of the pin under this urging. However, the force of such resilient means may be overcome by rotation of the grapple device relative to a yoke associated therewith about a longitudinal axis of the pin to unseat the protrusion from the recess.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
203 words
Apparatus for controlling oscillation of a first member relative to a yoke member defining first and second arm means, comprising: a pin; means for securing the pin from rotation about the longitudinal axis thereof relative to said first and second arm means; a housing member secured relative to said first member and positioned between said first and second arm means and defining a bore through which said pin is disposed; a retaining member disposed adjacent a first end of the pin and secured from rotation relative to one of the pin and housing member; resilient means associated with the second arm means and retaining member for urging the retaining member away from the second arm means; means for limiting movement of the pin under urging of the retaining member by the resilient means; the one of the pin and housIng member which is not secured from rotation relative to the retaining member, and the retaining member, together defining cooperating seatable protrusion and recess means, positioned so that rotation of the first member relative to the yoke member about the longitudinal axis of the pin causes unseating of the protrusion and recess means, against the resilience of the resilient means, from a seated position.
Claim 2
Dependent Claim
203 words
Apparatus for controlling oscillation of a first member relative to a yoke member defining first and second arm means, comprising: a pin; means for securing the pin from rotation about the longitudinal axis thereof relative to said first and second arm means; a housing member secured relative to said first member and positioned between said first and second arm means and defining a bore through which said pin is disposed; a retaining member disposed adjacent a first end of the pin and secured from rotation relative to one of the pin and housing member; resilient means associated with the second arm means and retaining member for urging the retaining member away from the second arm means; means for limiting movement of the pin under urging of the retaining member by the resilient means; the one of the pin and housIng member which is not secured from rotation relative to the retaining member, and the retaining member, together defining cooperating seatable protrusion and recess means, positioned so that rotation of the first member relative to the yoke member about the longitudinal axis of the pin causes unseating of the protrusion and recess means, against the resilience of the resilient means, from a seated position.
Claim 3
Dependent Claim
62 words
The invention of claim 1 wherein the means for securing said pin from rotation comprises an end member securable relative to the first and second arms, one of said end member and the second end of the pin defining a rib portion is complementary engagement with a channel defined by the other of the end member and second end of the pin.
Claim 4
Dependent Claim
23 words
The invention of claim 2 wherein second end of the pin defines the channel therein, and said end member defines the rib thereon.
Claim 5
Dependent Claim
42 words
The invention of claim 3 and means for allowing adjustment of the end member and pin about the longitudinal axis of the pin to allow securing of the pin relative to the first and second arm means in a chosen pivotal attitude.
Claim 6
Dependent Claim
17 words
The invention of claim 1 wherein the retaining member is secured from rotation relative to the housing.
Claim 7
Dependent Claim
19 words
The invention of claim 5 wherein the first end defines said recess, and said retaining member defines said protrusion.
Claim 8
Dependent Claim
14 words
The invention of claim 5 wherein the protrusion and recess are arcuate in cross-section.
Claim 9
Dependent Claim
23 words
The invention of claim 7 wherein the resilient means associated with said second arm means and said retaining member comprises a helical spring.
Claim 10
Dependent Claim
14 words
The invention of claim 1 wherein the protrusion and recess are arcuate in cross-section.
Claim 11
Dependent Claim
17 words
The invention of claim 1 wherein the retaining member is secured from rotation relative to the pin.
Claim 12
Dependent Claim
18 words
The invention of claim 10 wherein the retaining member defines said protrusion, and said housing defines said recess.
Claim 13
Dependent Claim
14 words
The invention of claim 11 wherein the protrusion and recess are arcuate in cross-section.
Claim 14
Dependent Claim
16 words
The invention of claim 12 wherein said pin and retaining member define a single unitary member.
Claim 15
Dependent Claim
22 words
The invention of claim 13 wherein the resilient means associated with said second arm means and retaining member comprise a helical spring.
