Abstract
Abstract Stabilizing apparatus for vehicles supporting load handling equipment such as tractors mounted with backhoes in which the stabilizing apparatus is movable vertically from a transport position to a ground engaging position and also may be moved horizontally to vary the angular disposition of the stabilizers relative to the vehicle to engage the ground at longitudinally spaced positions.

Claim 1
Independent Claim
221 words
Stabilizing apparatus for a vehicle supporting load handling equipment comprising a frame work having an elongated Cavity rigidly attached to each side of the vehicle; ground engageable support means, a strut member supporting said ground engageable support means relative to said vehicle, a shaft supporting said strut for pivotal movement about a horizontal axis for swinging movement of said ground engageable support means between a transport position and a ground engaged position, a bearing received in said cavity journaling one end of said shaft to said frame work, bracket means holding said bearing in a selected one of two positions in said cavity in which said shaft is displaced angularly and horizontally about its other end relative to said vehicle, including a bracket member, a plate and a bearing engaging pad on said, means detachably securing said plate to said plate, said plate covering one end of said shaft and said bearing in the attached position, said bearing engaging pad projecting from said plate toward said bearing to provide support on one side of said bearing with said plate in one position and on the other side of said bearing when said plate is rotated a half turn generally about the axis defined by said shaft for positioning said ground engageable support means in selected positions displaced longitudinally of said vehicle.
Claim 2
Dependent Claim
221 words
Stabilizing apparatus for a vehicle supporting load handling equipment comprising a frame work having an elongated Cavity rigidly attached to each side of the vehicle; ground engageable support means, a strut member supporting said ground engageable support means relative to said vehicle, a shaft supporting said strut for pivotal movement about a horizontal axis for swinging movement of said ground engageable support means between a transport position and a ground engaged position, a bearing received in said cavity journaling one end of said shaft to said frame work, bracket means holding said bearing in a selected one of two positions in said cavity in which said shaft is displaced angularly and horizontally about its other end relative to said vehicle, including a bracket member, a plate and a bearing engaging pad on said, means detachably securing said plate to said plate, said plate covering one end of said shaft and said bearing in the attached position, said bearing engaging pad projecting from said plate toward said bearing to provide support on one side of said bearing with said plate in one position and on the other side of said bearing when said plate is rotated a half turn generally about the axis defined by said shaft for positioning said ground engageable support means in selected positions displaced longitudinally of said vehicle.
Claim 3
Dependent Claim
14 words
The combination of claim 1 in which said bearing is a self aligning bearing.
Claim 4
Dependent Claim
20 words
The combination of claim 1 in which the other end of said shaft is journaled in self aligning bearing means.
Claim 5
Dependent Claim
42 words
The combination of claim 1 and further comprising hydraulic means for swinging said ground engageable support means between transport and ground engaging positions, one end of said hydraulic means being supported for horizontal pivotal movement during horizontal angular displacement of said shaft.
Claim 6
Dependent Claim
26 words
The combination of claim 1 wherein said bracket means includes a bearing receiving surface to support said bearing opposite the side of said bearing engaging pad.
Claim 7
Dependent Claim
132 words
Stabilizing apparatus for a vehicle supporting load handling equipment comprising; ground engageable support means, a strut member supporting said ground engageable support means relative to said vehicle, a shaft supporting said strut for pivotal movement about a horizontal axis for swinging movement of said ground engageable support means between a transport position and a ground engaged position, a bearing journaling one end of said shaft, bracket means forming an elongated cavity, a support member disposed in said cavity and forming a bearing receiving cavity adjacent one end of said elongated cavity, said support member being movable to a selected one of two positions to form said bearing receiving cavity adjacent the opposite end of said elongated cavity for positioning said ground engageable support means in selected position displaced longitudinally of said vehicle.
Claim 8
Dependent Claim
132 words
Stabilizing apparatus for a vehicle supporting load handling equipment comprising; ground engageable support means, a strut member supporting said ground engageable support means relative to said vehicle, a shaft supporting said strut for pivotal movement about a horizontal axis for swinging movement of said ground engageable support means between a transport position and a ground engaged position, a bearing journaling one end of said shaft, bracket means forming an elongated cavity, a support member disposed in said cavity and forming a bearing receiving cavity adjacent one end of said elongated cavity, said support member being movable to a selected one of two positions to form said bearing receiving cavity adjacent the opposite end of said elongated cavity for positioning said ground engageable support means in selected position displaced longitudinally of said vehicle.
Claim 9
Dependent Claim
78 words
The combination of claim 6 in which said bearing has an outer cylindrical surface, said cavity having surfaces at opposite ends thereof complementary to a portion of the outer cylindrical surface of said bearing, said support member having a surface in said elongated cavity complementary to the remaining portion of the outer cylindrical surface of said bearing, said surface of said support member and said surface at one end of said elongated cavity forming said bearing receiving cavity.
Claim 10
Dependent Claim
58 words
The combination of claim 6 in which said elongated cavity extends generally horizontally and in which opposite ends of said elongated cavity are similarly curved, said support member having opposite ends presenting curved surfaces complementary to the curved surfaces at the ends of said elongated cavity, said bearing being supported by said support member at one end thereof.
Claim 11
Dependent Claim
25 words
The combination of claim 6 in which said bearing is supported for horizontal sliding movement in said elongated recess upon removal of said support member.
Claim 12
Dependent Claim
30 words
The combination of claim 9 in which said bearing is movable from one end to the other of said elongated cavity upon relative movement of said stabilizer and said vehicle.
Claim 13
Dependent Claim
31 words
The combination of claim 10 in which said stabilizer is movable relative to said vehicle upon movement of the latter while said ground engaging support means are engaged with the ground.
