摘要： A self-plugging blind fastener (10, 74, 90) suitable for fastening apertured sheets together, and of the type comprising a body (12, 78) having a shank (16), headed at one end, and an axial bore (20) in which is disposed an elongate stem (14, 76, 92) which, in use, is pulled to expand the shank (16) and lock part of the stem (14, 76, 92) in the body (12, 78), has improved means for locking the stem (14, 76, 92) in the body (12, 78). The head end of the bore (20) is of reduced diameter and presents a stop-shoulder (30). The stop-shoulder (30) is an annular skirt (34) partly separated from surrounding material by an annular cleavage (32), and presents a planar stop-face (31, 84) facing away from the head-end. The stem (14, 76, 92) comprises a plug (42) which is connected by a breakneck (46) to a stem-tail (40) for pulling the plug (42) into the bore (20) of the body (12, 78).
The plug has an annular locking recess (50) spaced from the breakneck (46), and is radially enlarged on the side of the locking recess (50) remote from the breakneck (46) to provide a plug-shoulder (62) and shank-enlarging means (66, 68, 69). The plug-shoulder (62) presents a planar face (64, 94) for engaging the stop face (31, 84) of the body (12, 78) and deforming the annular skirt (34) into the locking recess (50) during setting of the fastener (10, 74, 90). The planar face (64) of the plug (42) and the planar stop-face (31) of the body (12) may both be at right angles to the axis of the bore (20), or either the planar face (94) or the stop-face (84) may be inclined at an angle not greater than 10° to a plane at right angles to the axis, thereby enabling deformation of the skirt (34) to begin at a lower force than would be required if the faces (64 and 84 or 31 and 94) were parallel.摘要翻译： 一种适于将有孔片材紧固在一起的自封闭盲链扣件（10,74,90），并且包括具有一端头的柄部（16）和轴向孔（20）的主体（12,78） ），其中设置有细长杆（14,76,92），其在使用中被拉动以使柄部（16）膨胀并且将躯干部分（14,76,92）锁定在主体（12,78）中， 具有用于将杆（14,76,92）锁定在主体（12,78）中的改进装置。 孔（20）的头端具有减小的直径并且具有止挡肩（30）。 挡肩（30）是通过环形裂缝（32）部分地与周围材料分离的环形裙部（34），并且具有面向远离头端的平面止动面（31,84）。 所述杆（14,76,92）包括塞子（42），所述塞子通过突出部（46）连接到杆尾（40），用于将塞子（42）拉入主体（12）的孔（20） ，78）。 插塞具有与突出部（46）间隔开的环形锁定凹部（50），并且在远离突出部（46）的锁定凹部（50）的侧面上径向扩大，以提供插头肩部（62）和柄部 放大手段（66,68,69）。 插头肩（62）具有用于接合主体（12,78）的止动面（31,84）并使环形裙部（34）变形成锁定凹部（50）的平面（64,94） 紧固件（10,74,90）的设置。 插头（42）的平面（64）和主体（12）的平面止动面（31）都可以与孔（20）的轴线成直角，或者平面（94） ）或止动面（84）可以以与轴线成直角的角度不大于10°的角度倾斜，从而使得裙部（34）能够以比所需的更小的力开始变形 面（64和84或31和94）平行。

摘要： A self-plugging blind rivet (10), of the kind comprising a tubular body (14) having a head (32) and a shank (30) which is deformed by means of a headed stem (12) which is disposed in the body (14) and pulled so as to form a blind head (60) and, if necessary, to cause the shank to bulb so as to grip workpieces of lesser thickness than the maximum for which the rivet is designed, is so shaped and dimensioned as to avoid the need for a crimping or hardening operation to be performed on the shank (30). Thus the shank (30) is made of uniform hardness, and has a waist (42) and a tail portion (40), the waist (42) being of reduced external diameter compared with the tail portion (40), and the tail portion (40) having a length B and an external diameter D which are related to satisfy the expression B=mD+n wherein
B is the length, in millimetres, of the tail portion (40);
D is the external diameter, in millimetres, of the tail portion (40);
n is a length, in millimetres, of from 2.15 to 2.73 millimetres,
and m is a number from 0.373 to 0.527 inclusive.摘要翻译： 一种自封式盲铆钉（10），其包括具有头部（32）和柄（30）的管状体（14），所述管状体（14）通过设置在主体中的头部杆（12）变形， （14）并且被拉动以形成盲目的头部（60），并且如果需要，引起柄部到灯泡以便夹持厚度小于铆钉设计的最大值的工件，其形状和尺寸如 以避免需要在柄（30）上进行压接或硬化操作。 因此，柄（30）由均匀的硬度制成，并且具有腰部（42）和尾部（40），与尾部（40）相比，腰部（42）的外径减小，并且尾部 （40）具有与满足表达式

摘要： Repetition pull-through blind riveting apparatus (10), of the type comprising a reusable and reloadable mandrel with an enlarged head which is pulled through each tubular rivet in turn to install the rivet is provided with a safety device (141) for counting the total number of times the mandrel has been pulled. The apparatus includes pneumatically-operated mandrel pulling means, and a counter (132) counts the number of times the pressure of the air powering the pulling device reaches a pressure slightly below that required to pull the mandrel head through a rivet. The counter (132) is arranged to actuate, when a safe limit number of pulls has been counted, both a shut-off valve (137) to shut-off the supply of pressure air to the mandrel pulling means, and a visual indicator (135). The visual Indicator (135) may be actuated at a warning count number rather lower than the safe limit number. The counter (132) can be reset to zero only by use of a separate key (142), when a new mandrel is installed in the rivet placing apparatus.

摘要： A swageable tubular member 12 for a pin and swageable member fastener of the type which carries a plurality of combination lock and breakgrooves, is provided with a projecting skirt 32 at that end of the collar which, in use, is remote from the workpieces and is the first to be swaged towards the pin. The skirt 32 is of reduced wall thickness, having an internal diameter which is greater than that of the remainder of the bore of tubular member, which it meets at an annular shoulder 34 which is substantially at right-angles to the bore axis. When the tubular member is swaged on to the pin, the skirt 32 does not engage the pin but projects beyond the pin-break which occurs adjacent the shoulder 34.

摘要： A breakstem blind rivet comprises a deformable tubular shell (11) of aluminium alloy having a bore (12) inside it. A stem (13) of low-carbon steel is a close fit within the bore, extending along the bore and having a head (14) adjacent the tail end (15) of the shell. The outside of the shell is formed with at least three zones (27, 28, 29) of modified strength spaced apart along its length, these zones being in the form of shallow grooves rolled into the surface. The spacing between each zone (27, 28, 29) and the next progressively decreases as the distance along the shell from the tail end (15) increases. Alternatively the grooves may be formed by a turning process.

摘要： A device for automatically replenishing and exchanging hydraulic fluid in the hydraulic system (such as that of a fastener placing tool (31)) comprises a lower reservoir (29) for holding new hydraulic fluid (39) and an upper reservoir (28) for receiving old hydraulic fluid. The device connects with the system to be replenished by means of a single hydraulic fluid connection (17) at the bottom of the lower reservoir (29). An entry port (25) to the second reservoir is positioned opposite the connection (17) at the bottom end of a tube (23) leading to the top of the second reservoir.
In use, the device is connected to the hydraulic system through the connection (17) and the system is pressurised. Old hydraulic fluid is forced up through the connection (17) at high speed and passes through the new hydraulic fluid (39) in the lower reservoir (29), through the port (25), up the tube (23) and down into the upper reservoir (28) where it is retained. When the system is depressurised, new hydraulic fluid (39) is drawn down through the same connection (17) into the hydraulic system.摘要翻译： 用于在液压系统（例如紧固件放置工具（31）的液压系统中）自动补充和更换液压流体的装置包括用于保持新的液压流体的下部储存器29和用于接收的上部储存器28） 旧液压油。 该装置通过在下部储存器（29）的底部的单个液压流体连接（17）与要补充的系统连接。 到达第二储存器的入口（25）在通向第二储存器顶部的管（23）的底端处与连接件（17）相对定位。 在使用中，设备通过连接（17）连接到液压系统，系统被加压。 老液压油被高速地通过连接件17上升，并通过下部贮存器29中的新的液压流体39通过端口25向上穿过管子23并向下进入 上部储存器（28）保留。 当系统减压时，新的液压油（39）通过相同的连接（17）向下拉入液压系统。

摘要： A hand-held rivet installation tool is provided with an air- flow ejector (23, 26, 28) to eject broken off rivet stems. The tool has a base (71) on which it can stand on a level surface. A valve (73) is provided with its actuating plunger (75) protruding from the base. When the tool is standing on its base, the plunger (75) is pushed in and the valve (73) shuts off the air supply to the ejector. When the tool is picked up again the valve (73) stays in the off position until the toot-actuating trigger (31) is operated again. Thus needless waste of air through the ejector, when the tool is not being used, is eliminated.
