20130240299 | LUBRICATION ARRANGEMENT - A lubrication system for a work tool, such as a demolition hammer, on a machine, such as an excavator or a loader. The lubrication system is mounted on drive line fluid connectors of the machine, such as hydraulic or pneumatic hoses. The lubrication system is fully supported by the connectors only and does not require mounting to the machine itself. The lubrication system includes a movable spool powered by the drive fluid of the machine, the spool reciprocating within a sleeve to force lubricant through passages to the work tool. | 09-19-2013 |
20140102740 | Front Head Nut Pocket Configuration for Hydraulic Hammer - A hydraulic hammer may include a power cell adapted to reciprocally drive a piston along an axis. The piston may, in turn, drive a hammer tool having a first end juxtaposed against the piston for accommodating cyclic impacts by the piston. While the first end of the hammer tool may be contained within a housing, the other end may extend from the housing for impacting rock, for example. The power cell and housing are axially secured together by a plurality of tie rods and nuts secured to ends of the tie rods, and the housing may include exterior pockets for accommodating the nuts. Each nut may have a circular exterior surface, and each nut pocket may have a generally elliptical interior surface, such that the exterior surface of each nut may be configured to engage at least two spaced apart areas of a corresponding interior surface of each nut pocket. | 04-17-2014 |

20120043163 | Lubrication System for a Breaking Tool - A lubrication system for a work tool, such as a demolition hammer, that is powered by a drive fluid. The lubrication system including a valve member movable from a first position to a second position in response to receiving an input indicative of a low level of a lubricant, wherein in the second position, the valve member is configured to divert the drive fluid to shutdown or derate the tool. | 02-23-2012 |
20140208575 | TIE ROD SUPPORT FOR HYDRAULIC HAMMER - A hydraulic hammer may include a power cell adapted to reciprocally drive a piston along an axis. The piston may, in turn, drive a hammer tool. A power cell and housing may be axially secured together by a plurality of tie rods and nuts secured to ends of the tie rods, and the housing may include open-sided pockets for accommodating the nuts. Each pocket may include a cavity that accommodates an extension of the tie rod or a specially formed nut to minimize movement of the nut in the direction of the pocket opening and thereby minimize bending of the tie rod. Engaging the back of the nut with the inside of the nut pocket further reduces the opportunity for the nut to rotate in the nut pocket as a result of force applied to the nut by the tie rod. | 07-31-2014 |
20140219741 | RECEPTACLE ARRANGEMENT FOR ELONGATED FASTENER AND NUT - A receptacle arrangement for an elongated fastener and a nut is disclosed. The receptacle arrangement includes an assembly of two or more stacked blocks. The assembly defines an elongated receptacle extending through a first block up to a mid portion of a second block. The elongated receptacle is configured to receive the elongated fastener. A receptacle obliquely extends across the elongated receptacle and mutually adjoining surfaces of the second block. The receptacle is configured to slidably receive the nut such that the elongated fastener engages into the nut. | 08-07-2014 |

20080267379 | CALCULATING A FULLY QUALIFIED NUMBER - A teleconference server may calculate a fully qualified number (FQN), which specifies a string of numbers that, if dialed by an calling party, will establish a call with a called party. The fully qualified number may include, for example, an external access code, an international access code, a country code, a national destination code, and/or a subscriber number. In order to determine a calling party and a called party, the teleconference server may access data regarding a scheduled call. The teleconference server may determine a fully qualified number based on the relationship between the called party and the calling party. The teleconference server may send the fully qualified number to the calling party, which may then initiate a scheduled call with the called party by dialing the received fully qualified number. | 10-30-2008 |
