  • Patent number: 10906108
    Abstract: An accessory includes a blade, a coupling, and a guide. The blade includes a cutting edge. The coupling includes a first portion and a second portion. The first portion is attachable to and detachable from the power tool. The second portion is connected to the blade. The guide is structured to guide the blade along a work piece by interacting with a surface of the work piece as the blade moves in an advancing direction. The guide is structured to provide a locked state and an unlocked state. In the locked state, the guide is engaged with the coupling such that the guide is attached to the coupling. In the unlocked state, the guide is disengaged from the coupling such that the guide is detached from the coupling.

  • Publication number: 20130263755
    Abstract: Prior to immersion into the ballast, a hand tamper (1) for tamping a track is detachably connected to an anchor element (10), fixed to the track (9) and lying opposite with regard to a tamping motion (18), by means of a fixing member (15) fastened to a tamper section (6) situated between a drive motor (3) and a tamping blade (5). Thus, an improved compaction effect can be achieved.

  • Patent number: 7013812
    Abstract: The present invention comprises a tamping tool comprising a shank and a blade, with the blade having various arrangements of wear-resistant material affixed to the face of the blade by means of brazing, soldering, gluing or other method. Additionally, some arrangements of the tamping tool have a wear-resistant tip inserted into a groove in the end of the blade. The tamping tool of the present invention reduces wear, providing an increased life and increasing the time intervals at which it becomes necessary to replace the tamping tool.

  • Patent number: 6640406
    Abstract: A railroad clip applicator system for efficiently securing a fastening clip to a receiver bracket of a crosstie. The railroad clip applicator system includes a housing, a handle structure attached to the housing, an actuator secured within the housing, an engaging structure attached to the actuator for engaging a fastening clip, and a pair of lower arms extending from the housing to engage a lower side of a rail. The engaging structure is comprised of a pair of guide pins slidably positioned within the housing, and an engaging member having a center member and a rear member for engaging the rear portion of the fastening clip. The actuator forces the engaging structure forwardly thereby causing the fastening clip to slide within the tapered slot of the receiver bracket until the fastening clip is fully secured upon the receiver bracket.

  • Patent number: 6622361
    Abstract: A railroad clip removal system for efficiently removing a fastening clip from a receiver bracket of a crosstie. The railroad clip removal system includes a frame structure having a center cutout and a pair of opposing slots, an actuator, a pair of engaging arms pivotally attached to the actuator and slidably positioned within the opposing slots. The engaging arms have a catch portion that engages the fastening slip while the engaging arms simultaneously compress the prongs of the fastening clip thereby removing the fastening clip from the receiver bracket of a crosstie.

  • Patent number: 6581524
    Abstract: A conversion device that is structured to be coupled to the rotating axle of a motor and to an output assembly. The output assembly has an elongated shaft with an axis extending generally perpendicular to the axis of the motor axle. The output assembly further is coupled to a frame to resist movement in an axial direction. The conversion device includes an eccentric hub having a disk with a sidewall extending from the perimeter thereby forming a recess and a yoke having a shaft and an attachment pin. The disk is coupled to the motor axle. The yoke shaft is disposed within the eccentric hub recess and the attachment pin is pivotally coupled to the output assembly. As the eccentric hub is rotated by the motor, the hub causes the yoke moves in a circular path. The circular path of the yoke has directional components that are parallel to the axis of the output assembly shaft and perpendicular to the axis of the output assembly shaft.

  • Patent number: 4327645
    Abstract: The handle of a tie tamper is connected to its vibration generating motor, to which a beater is rigidly fixed to be vibrated thereby, by a combination of a Neidhart damper fixed to one end of the handle, a shackle-link pair fixed at one end to the square shaft of the damper, and an arcuate leaf spring pin-connected at its one end to the link pair and at its other end to the motor and by a two-bar linkage connected at its two ends via Neidhart dampers respectively to an intermediate part of the handle and to the motor, and a balance weight is provided at the pin joint between the two links of the two-bar linkage. This construction greatly reduces the vibration transmitted from the motor to the handle.
