Hydraulic cylinder limiter
A limiter bracket, for restricting the stroke of a hydraulic cylinder, is formed from a U-shaped member having a central base portion and two opposing sidewall. The base has a semi-circular retention slot extending from an off center position centrally located detent within the base. The opening of the slot is asymmetrically located at an off center position along an edge of the base so that the rod of a cylinder is both horizontally and vertically displaced during positioning within the limiter. Once the rod is located in the detent of the limiter, a pivot pin is inserted through a connector at the end of the rod and the aligned attachment holes in the sidewalls securing the limiter to the rod. The end of the cylinder body will contact the base of the limiter during retraction of the rod thus limiting the overall stroke of the cylinder.
1. A limiter bracket for a cylinder comprising:
a U-shaped member having a central base portion and two opposing sidewalls generally perpendicularly connected to opposing first and second sides of the base;
the base having a slot extending from a mouth in a third side of the base to a retention detent generally located along a vertical centerline of the base, wherein the mid point of the mouth of the slot is horizontally offset from the vertical centerline; and
each sidewalls having an attachment opening aligned with the opening of the opposing sidewall.
2. The limiter bracket as claimed in claim 1 , wherein the slot extends vertically in a direction generally perpendicular to the third side of the base.
3. The limiter bracket as claimed in claim 1 , wherein:
the slot extends angularly across the base from the mouth to the retention detent.
4. The limiter bracket as claimed in claim 1 ; wherein the retention detent is semi-circular and the center point of the detent and center points of the attachment are located at generally equal vertical heights.
5. The hydraulic cylinder assembly as claimed in claim 1 ; wherein the retention detent is semi-circular and the center point of the detent and center points of the attachment are located at generally equal vertical heights.
6. A hydraulic cylinder assembly comprising:
a hydraulic cylinder having a cylinder rod;
a connector attached to an external end of the cylinder rod;
a U-shaped member having a central base portion and two opposing sidewalls generally perpendicularly connected to first and second opposing sides of the base;
the base having a slot extending from a mouth in a third side of the base to a retention detent generally located along a vertical centerline of the base, wherein the mid point of the mouth of the slot is horizontally offset from the vertical centerline; and
each sidewall having an attachment hole aligned with the hole of the opposing sidewall, wherein a pivot pin is inserted through the end connector and both attachment openings.
7. The hydraulic cylinder assembly as claimed in claim 6 , wherein an inner surface of each sidewall is in general contact with the connector.
8. The hydraulic cylinder assembly as claimed in claim 6 , wherein the slot extends vertically in a direction generally perpendicular to the third side of the base.
9. The hydraulic cylinder assembly as claimed in claim 6 , wherein:
the slot extends angularly across the base from the mouth to the retention detent.
