Abstract
A spike claw puller for pulling a rail spike has a handle a first feeder tooth and a second feeder tooth. The handle includes a feature for coupling the spike claw puller to a rail spike pulling machine. The first and second feeder teeth extend from the handle and form a jaw opening therebetween to receive a rail spike. The first feeder tooth includes a first feeder extension and the second feeder tooth includes a second feeder extension to help align the spike claw puller with the rail spike.
Claims18
A spike claw puller for pulling a rail spike, the spike claw puller comprising:
- a handle defining a through hole configured to couple the spike claw puller to a rail spike pulling machine;
- a first feeder tooth extending from the handle at a first lift angle;
- a second feeder tooth extending from the handle at the first lift angle, the first feeder tooth and the second feeder tooth forming a jaw opening therebetween to receive the rail spike, wherein the first feeder tooth includes a first feeder extension and the second feeder tooth includes a second feeder extension to help align the spike claw puller with the rail spike;
- a first transition surface disposed at a transition from an underside of the first feeder tooth to an underside of the first feeder extension;
- and
- a second transition surface disposed at a transition from an underside of the second feeder tooth to an underside of the second feeder extension, the first transition surface and the second transition surface each being rounded;
- wherein the first feeder extension comprises a first slanted edge and the second feeder extension comprises a second slanted edge to help align the spike claw puller with the rail spike;
- wherein the first and second feeder extensions protrude at a second lift angle from the first and second feeder teeth, respectively, and wherein the second lift angle is different than the first lift angle.
