Abstract
A lifting tool for lifting water meter covers including a hook member contoured and sized to go through the hole in the water meter cover and a telescoping sleeve member around the shank of the hook member, adapted to move up and down relative to the hook member, and including a spacing member for forcing the hook at the end of the hook member to engage the bottom of the water meter cover to facilitate lifting of the cover.
Claims3
A device for lifting articles, which articles include a hole of fixed size extending through such article, said device comprising:
- 1. Rod means with offset means on one end thereof said offset means and rod means being of a size so as to be insertable through said article in said hole;
- 2. Tab means attached essentially perpendicularly to said rod at a distance from said offset means;
- 3. Elongated cylindrical means slideably mounted about said rod means, with said offset means extending outwardly from the first end of said cylindrical means, said cylindrical means having an elongated opening in its wall suitable to allow said tab means to project outwardly therethrough and of such length that said rod means with said tab means attached can slide within said cylindrical means;
- 4. Lever means pivotally attached to said cylindrical means at its second end;
- 5. Means cooperative with the said first end of said cylindrical means which means prevent said cylindrical means from entering the said hole in said article;
- and
- 6. Connecting means pivotally connecting said tab means to said lever means in such manner that the said rod means is forced into said cylindrical means so as to bring the said offset means closer to the said first end of said cylindrical means when the lever means is moved in one direction and so that said offset means is moved away from said first end of said cylindrical means when the said lever means is moved in the other direction.
A device for lifting articles which have a hole extending through the thickness of such article comprising:
- 1. An elongated member having handle means upon its first end and pivotal connecting means on its second end;
- 2. An elongated cylinder pivotally connected at its first end to the said pivotal connecting end attached to said handle;
- 3. Means attached to the second end of said elongated cylindrical means, which means are such size that said means cannot pass into the hole of the said article;
- 4. Wedge means attached to said means which will not pass into the hole, in such manner that said wedge means can pass into the said hole;
- 5. Rod means slideably mounted within said cylindrical means and extending a distance upon one end therefrom;
- 6. Hook means fastened to the rod means at its end extending from said cylindrical means, said hook means being of such size that it can pass through the hole in said article, but of such size that it cannot pass through the said hole when the said wedge means is in position within said hole;
- 7. Tab means attached to said rod means at a point within said cylinder means, and extending outwardly through said cylinder means in a slot formed in said cylinder means;
- and
- 8. Connecting means pivotally connected between said handle means and said tab means in such manner that when said handle means is moved in a direction away from the end of said rod having said hook means, the said hook means is moved toward the said cylinder means, and when said handle means is moved in the other direction the said hook means is forced outward and away from said cylinder means.
