摘要： A cutting tool assembly mounted on a rotating drum and having a base block, a wear sleeve and a cutting bit wherein a seal is located between the base block and wear sleeve is disclosed. A fluid passage spans from the rotating drum to a discharge location between the wear sleeve and the shank of the cutting bit. The fluid lubricates the shank of the cutting bit and bore of the wear sleeve allowing the cutting bit to rotate freely within the wear sleeve. Rotation of the cutting bit promotes even wear and long life of the bit.

摘要： A tooth holder for a cutter of a mining machine has a holder body fixed to the cutter and normally displaced thereby in a predetermined longitudinal direction. This body is formed with a longitudinally generally forwardly open bore, an outer transversely directed seat face adjacent the bore, and a feed passage opening at the outer seat. A sleeve is received in the bore and a cutter tooth is received in the sleeve. A separate nozzle body is formed with a nozzle passage having one end communicating with the feed passage at the seat and an opposite end forming a longitudinally generally forwardly open spray mouth, and a face complementary fitted to the outer seat face. A fluid is supplied under pressure to the feed passage so that the fluid exits the spray mouth. The nozzle body is releasably secured by screws or the like to the holder body with the faces engaged tightly together.

摘要： A tool is mounted in a holder, the holder including a fluid passage for discharging drilling fluid toward a cutting zone. Fluid flow is regulated by a valve in the holder. The valve includes a housing and a valve element movable in the housing. The valve element opens the valve in response to rearward displacement of the tool relative to the holder. The housing of the valve is also rearwardly displaceable relative to the holder whenever rearward forces transmitted from the tool are excessive, thereby avoiding the occurrence of damage to the valve. The valve housing is yiealdably biased forwardly by fluid pressure in the conduit.

摘要： A liquid spray jet assembly is disclosed destined particularly for use in dust and debris laden conditions such as on the cutting heads of mineral mining machines. The assembly comprises a housing for securing to a piece of apparatus, a jet which is a push fit into the interior of the housing and a resilient seating between the jet and a part of the housing. The seating is made from a compressible material and is so compressed by the jet when positioned in the housing that the restoring force causes part of the jet to bear against a surface of the housing facing towards the seating so holding the jet within the housing. The housing and the jet have communicating passages for the passage of liquid therethrough. Use of a push fit avoids the previously used screw threaded communications and makes jet replacement an extremely simple operation.

摘要： A roadway milling machine includes a hollow, cylindrically walled, shaft mounted, imperforate drum having tungsten carbide tipped steel cutting tools supported in tool holders extending generally radially outwardly from the cylindrical surface of the drum. The drum is moved over a roadway to be milled, and is rotated on its shaft to bring the cutting tools into operative contact with the roadway. Water is fed into the drum along a water access opening provided along the axis of the drum shaft; and this coolant leaves the drum through openings provided in the cylindrical drum wall, one adjacent to each cutting tool, in position where the coolant leaving the drum will impinge upon and cool its adjacent cutting tool. In order to limit the flow of water from the drum to the cutting tools and, at the same time, to prevent the necessarily small openings from clogging up, large openings can be provided through the cylindrical drum wall and well into the tool holders which extend integrally outwardly from that wall. A transverse opening through each tool holder is open to the tool holder large radial opening in the tool holder. This transverse opening is almost completely fitted with a bolt or other rod-like structure. The minimum cross-sectional area of the bolt is less than that of the transverse slot, and the bolt is free to vibrate or otherwise move under the impetus of the shock to the tool and tool holder as the tool strikes the roadway on each rotation of the drum.
摘要翻译：道路铣床包括中空的圆柱形壁安装的无孔滚筒，其具有支撑在从滚筒的圆柱形表面大致径向向外延伸的刀架中的碳化钨切削钢切割工具。将滚筒移动到要铣削的道路上，并在其轴上旋转以使切割工具与道路操作地接触。水沿着沿着鼓轴的轴线设置的进水口被送入滚筒; 并且该冷却剂通过设置在圆筒形鼓壁中的开口离开滚筒，该开口邻近每个切削工具，其中离开滚筒的冷却剂将撞击并冷却其相邻的切割工具。为了限制水从滚筒到切割工具的流动，并且同时为了防止必要的小开口堵塞，可以通过圆柱形鼓壁提供大的开口并且很好地提供到延伸的工具架中从该墙整体向外。通过每个刀架的横向开口对刀架保持器的大径向开口开放。该横向开口几乎完全装配有螺栓或其他棒状结构。螺栓的最小横截面积小于横向槽的最小横截面面积，并且当工具在每次旋转时工具撞击道路时，螺栓可自由振动或以冲击的动力移动到工具和工具架上鼓。

摘要： A shearer drum for a mining machine used in underground mining is provided with cutter picks and nozzles on the periphery of the drum. The nozzles are subdivided into groups which extend substantially parallel to the rotational axis of the drum and each group of nozzles can, when disposed opposite the mine face, be connected by a controllable valve associated with the group to a line for supplying high-pressure liquid. An independent control valve and at least one cutter pick are associated with each nozzle group. The cutter pick is resiliently mounted and cutting pressure triggered by movement of the cutter pick into a mine face actuates the control valve and connects the nozzles to the high-press line.

摘要： A coolant system for mining bits which are rotatably mounted in blocks secured to mining machines of the type utilizing a large rotating wheel or continuous power-driven chains. The mounting blocks for the bits have a coolant passage leading to a bore in the block. Within the bore is a coolant dispensing sleeve which has a central passage to receive the shank of a mining bit. The sleeve has one or more axially disposed spray nozzles which receive coolant under pressure from the coolant passage in the block and from an annular passage formed between the block and the sleeve.
