Benefits of technology

The patent describes a new design for a tamping tool used in construction that increases the lifespan of tiles and reduces the amount of time and cost. The tool has ridges that serve as impact barriers between different tiles and transfer forces to the ridges instead of the adjacent tiles, preventing wear and tear. Additionally, the nose wear tiles are designed to match the profile of the front end of the paddle, allowing for a single braze installation and potentially larger penetrating tip shapes.

Problems solved by technology

As such, the lifespan of surface wear tiles, nose wear tiles, and the paddle is dramatically increased.

Embodiment Construction

[0027]Referring to the drawings, various exemplary embodiments of an improved tamping tool are provided. It is to be understood that the following explanation is merely exemplary in describing the devices and methods of the present disclosure. Accordingly, several modifications, changes, and / or substitutions may be contemplated.

[0028]FIG. 1 illustrates an exemplary tamping tool 100. The tamping tool 100 may include a shank portion 102, a paddle 104, and a plurality of wear tiles 106, 108. In some embodiments, the shank 102 and the paddle 104 may be integrally formed. It should be appreciated, however, that in other embodiments, the shank 102 and the paddle 104 may be coupled in other ways, including welding, being detachedly and / or operatively coupled to each other, and / or the like.

[0029]The shank 102 and the paddle 104 may be manufactured as a common piece or different pieces coupled together. The shank 102 and the paddle 104 may be formed of a rigid material such as metal (e.g., i...

Abstract

The present disclosure generally relates to an improved railroad track ballast tamping tool. The tamping tool may be lowered into ballast underlying railroad tracks and between railroad track ties for performing ballast tamping operations. The tamping tool includes a shank and a paddle coupled to the shank. The paddle comprises a top ridge disposed on a top surface of the paddle and a bottom ridge disposed on a bottom surface of the paddle. The tamping tool additionally includes a top surface wear tile coupled to the top surface of the paddle and abutting a rear face of the top ridge, a bottom surface wear tile coupled to the bottom surface of the paddle and abutting a rear face of the bottom ridge, and a nose wear tile coupled to the top and bottom surfaces of the paddle and abutting a front face of both the top and bottom ridges.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application is a nonprovisional application of, and claims priority to, U.S. Provisional Patent Application No. 62 / 322,027 filed on Apr. 13, 2016, the contents of which are hereby incorporated by reference in entirety.BACKGROUND[0002]Railroads are generally constructed of a pair of elongated, substantially parallel rails, which are coupled to a plurality of laterally extending ties via metal tie plates and spikes and / or spring clip fasteners. The rails and ties are disposed on a bed formed of hard particulate material, such as gravel. This hard particulate material, which is called ballast, often underlies or surrounds the rails and ties.[0003]During operation of the railroad, underlying ballast tends to shift or move from its position relative to the rails and ties. As such, a level of support provided by the ballast may be unwantedly reduced. To maintain the ballast, the ballast adjacent to and / or under the ties may be “tamped,” or...
