Abstract
A tool for driving wooden plugs in spike holes of railroad ties following removal of railroad spikes from the wooden tie prior to track regauging and/or replacement. An elongated main body rod of steel is provided having a permanently affixed collar or washer at one extreme end thereof and another permanently affixed collar or washer approximately midway thereof. Slidably mounted between the two collars is a hand-operated driving weight. The other end of the elongated rod has a reduced rod extension portion which has a slidable plug holding sleeve thereon. The extreme tip of this other end is threaded and receives an adjusting nut on the threads for predetermining the desired depth of wooden plug driving into a railroad tie.
Claims18
A manually operated tool for driving wooden plugs into railroad ties, comprising:
- (a) an elongated rod;
- (b) collar means affixed to said elongated rod for engagement by a drving weight;
- (c) a driving weight defining an aperture extending therethrough slidably mounted on said rod;
- (d) cap means fixedly located at a first end of said rod and retaining the driving weight on said rod between said collar means and said cap means;
- (e) tip means located at a second end of said rod for continuously maintainng contact with a wooden plug being driven;
- (f) stop means associated with said tip means, for engaging an upper surface of a railroad tie plate when a plug has been driven to a predetermined countersunk depth and limiting the depth to which said wooden plug can be countersunk below said upper surface into said railroad tie by said tool.
- (g) a tip aligning sleeve mounted slidably on said second end, said sleeve being movable between a position in which said sleeve extends beyond said tip means, and a position in which said tip means extends beyond said sleeve.
A plug driver for holding and inserting wooden plugs into railroad spike apertures in railroad ties prior to re-gauging or reinstalling railroad tracks on said ties, comprising:
- (a) an elongated rod;
- (b) a first collar affixed to one end of said rod;
- (c) a second collar affixed to said rod;
- (d) a driving weight slidably mounted on said rod between said collars;
- (e) a reduced diameter extension rod portion on the other end of said rod;
- (f) tip means located at said other end for continuously maintaining contact with a wooden plug being driven;
- (g) tip-aligning sleeve means, slidably disposed on said reduced diameter extension rod portion, for holding said tip means aligned with a wooden plug, said sleeve means being movable between a position in which said sleeve means extends beyond said tip means, and a position in which said tip means extends beyond said sleeve means;
- and
- adjustable stop means for engaging an upper surface of a tie plate and establishing the depth to which a wooden plug can be driven below said upper surface, said stop means comprising threads on said tip means and an adjusting nut mounted on said threads.
