WHEEL WEIGHT ASSEMBLY FOR A TRACTOR
First Claim
1. A multiple weight assembly in the class described, comprising:
- a first weight having mounting means for the affixation thereof to a support or the like;
said first weight having an outer side and being provided thereat with a pair of shoulders;
said shoulders respectively including a pair of spaced apart engaging surfaces which are upwardly facing and are inclined to converge downwardly toward the weight inner side when the first weight is in a position for assembly;
a second weight outwardly of said first weight and having an inner side and being provided thereat with a pair of hooks respectively having downwardly facing surfaces inclined parallel to and engaged with said upwardly facing surfaces of said shoulders of said first weight;
whereby said second weight may be hangingly suspended from said first weight to free both hands of the operator;
a first, upwardly inclined groove in the outer side of said first weight located below and vertically between said first pair of shoulders;
a second upwardly inclined groove in said inner side of said second weight located below and vertically between said pair of hooks and being axially aligned with said first groove; and
a clamping bolt inserted into said grooves and having a nut tightened on one end thereof so as to secure the first and second weights together.

Abstract
Individual, ring-shaped wheel weights are provided as ballast for increasing the traction of a tractor. The weights are constructed to be mounted coaxially, one against the other, in numbers sufficient to supply the ballast desired. The first weight mounted is bolted to the outer face of the wheel disc and the weights added thereafter are secured in succession only to the adjacent previously mounted weight. The connection between the adjacent weights is effected by a pair of interengaged hook and shoulder connection parts in cooperation with a bolt which is inserted into and held by a nut in an opening formed by cooperating, U-shaped grooves in the adjacent weights. The hooks, shoulders and grooves are so disposed relative to each other that by tightening the nut on the bolt the hooks of the weight being mounted become tightly engaged with the shoulders of the adjacent mounted weight.

said shoulders respectively including a pair of spaced apart engaging surfaces which are upwardly facing and are inclined to converge downwardly toward the weight inner side when the first weight is in a position for assembly;
a second weight outwardly of said first weight and having an inner side and being provided thereat with a pair of hooks respectively having downwardly facing surfaces inclined parallel to and engaged with said upwardly facing surfaces of said shoulders of said first weight;
whereby said second weight may be hangingly suspended from said first weight to free both hands of the operator;
a first, upwardly inclined groove in the outer side of said first weight located below and vertically between said first pair of shoulders;
a second upwardly inclined groove in said inner side of said second weight located below and vertically between said pair of hooks and being axially aligned with said first groove; and
a clamping bolt inserted into said grooves and having a nut tightened on one end thereof so as to secure the first and second weights together.
- a first weight having mounting means for the affixation thereof to a support or the like;
-
2. The invention defined in claim 1 wherein the inclination of said grooves is steeper than the inclination of the engaged hook and shoulder surfaces whereby said hook and shoulder surfaces will become more tightly engaged when said nut is tightened.
-
3. The invention defined in claim 1 wherein the first and second weights include upper and lower edges with respect to their position when being mounted;
- a central opening in each of the first and second weights between their upper and lower edges, and the upper end of said groove in the inner face of said second weight opening into said opening;
said bolt being inserted into the last-mentioned groove such that the nut is located at the upper end thereof whereby said nut is accessible and may be tightened through said opening.
- a central opening in each of the first and second weights between their upper and lower edges, and the upper end of said groove in the inner face of said second weight opening into said opening;
-
4. The invention defined in claim 1 wherein the inner and outer sides of said first and second weights are generally planar and the hooks and shoulders of the weights are arranged such as to permit the weights to be assembled in side-to-side engagement.
-
5. The invention defined in claim 4 wherein said weights are circular and wherein said engaged surfaces of the pairs of hooks and shoulders converge toward a common point on the axis of the weights.
-
6. The invention defined in claim 5 wherein said engaged surfaces of said pairs of hooks and shoulders are angularly spaced approximately 90* about the axis of the weight.
-
7. The invention defined in claim 5 wherein the weights are ring-shaped, thus defining a central opening therein between their upper and lower edges, and the upper end of said groove in the inner face of said second weight opening into said opening;
- said bolt being inserted into the last-mentioned groove such that said nut is located at the upper end thereof whereby said nut is accessible and may be tightened through said opening.
-
8. The invention defined in claim 7 wherein said first and second weights are identical whereby they may be mounted in any order in the assembly.
-
9. The invention defineD in claim 8 wherein said mounting means includes at least three equispaced recesses in the inner circumference of said ring-shaped weights, said recesses each including a pair of axially aligned conical surfaces converging towards each other from the inner and outer sides of the weights;
- conical centering washers located in said conical surfaces of said first weight and bolts inserted into said washers and being adapted for insertion into said support; and
nuts on the bolts.
- conical centering washers located in said conical surfaces of said first weight and bolts inserted into said washers and being adapted for insertion into said support; and
-
10. The invention defined in claim 1 wherein the interfaces of the engaged surfaces are inclined towards a common point on a horizontal axis extending perpendicular to the inner and outer sides of said first and second weight elements and are tangent to the surface of a cone generated about the axis and having its apex at said common point.
-
11. A multiple weight assembly in the class described, comprising:
- a first weight having mounting means for the affixation thereof to a support or the like; and
first weight having an outer side and being provided thereat with a pair of spaced apart shoulders;
said shoulders respectively including a pair of engaging surfaces which are upwardly facing and are inclined to converge downwardly toward the weight inner side when the first weight is in a position for assembly;
a second weight outwardly of said first weight and having an inner side and being provided thereat with a pair of hooks respectively having downwardly facing surfaces inclined parallel to and engaged with said upwardly facing surfaces of said shoulders of said first weight;
whereby said second weight may be hangingly suspended from said first weight to free both hands of the operator, and clamping means securing said second weight to said first weight and serving as the sole connection between said first and second weights.
- a first weight having mounting means for the affixation thereof to a support or the like; and
-
12. The invention defined in claim 11 wherein the interfaces of the engaged surfaces are inclined towards a common point on a horizontal axis extending perpendicular to the inner and outer sides of said first and second weight elements and are tangent to the surface of a cone generated about the axis and having its apex at said common point.
-
13. The invention defined in claim 11 wherein the inner and outer sides of said first and second weights are generally planar and the hooks and shoulders of the weights are arranged such as to permit the weights to be assembled in side-to-side engagement.
-
14. The invention defined in claim 13 wherein said weights are circular and wherein said engaged surfaces of the pairs of hooks and shoulders converge toward a common point on the axis of the weights.
