摘要： A hand held pneumatic screw aligner feeder device which may be used in any orientation incorporates a container for loose screws made up of two cup shaped walls forming a hopper, a groove between the walls used to align the screws, a separator to keep unaligned screws out of the groove, a chute to carry the screws to a pawl which allows only a single screw to be delivered to a transfer chamber and an inlet for compressed air along one of the hopper walls. The device may be coupled to a pneumatic screw tightener such that a screw in the transfer chamber is forced down a hose to the nose of the tightener so that the screw may be forced into an external surface. An actuating valve system within the aligner feeder tightener device, coupled to the tightener nose allows compressed air to flow to the aligner feeder when the tightener is not in use, and to the tightener only when the tightener is activated.
摘要翻译：可以以任何方向使用的手持气动螺旋定位器进给器装置包括用于由形成料斗的两个杯形壁组成的松散螺钉的容器，用于对准螺钉的壁之间的槽，用于保持未对准的螺钉的分离器的槽，用于将螺钉运送到棘爪的滑槽，其仅允许单个螺杆被输送到沿着一个料斗壁的转移室和用于压缩空气的入口。该装置可以联接到气动螺丝紧固器，使得传送室中的螺杆被迫使软管到达紧固器的鼻部，使得螺钉可以被迫进入外表面。在紧固器鼻孔处连接到对准器进料器紧固器装置中的致动阀系统，当紧固器不使用时，压缩空气仅在紧固器被激活时才允许压缩空气流到对准器进料器。

摘要： This striking tool of an internal combustion type includes in a housing of a tool body a cylinder providing slidably a piston connecting to a driver. A combustion chamber is disposed around the side wall of the cylinder. A fluid controlled valve is disposed between the combustion chamber disposed around the side wall of the cylinder. A fluid controlled valve is disposed between the combustion chamber and a piston upper chamber of the cylinder, which is normally biased to close communication between the combustion chamber and the piston upper chamber and operated to open communication therebetween when mixture gas of combustible gas and air in the combustion chamber is exploded therein. When a trigger, disposed on the external of the tool body and driveable outwardly, is driven, said mixture gas at first enters and fills up the combustion chamber and then is ignited therein by igniting means. A rising of combustion pressure generated by ignition of mixture gas in the combustion chamber directly opens said valve. The combustion pressure is, thereby, supplied into the piston upper chamber of the cylinder and pressurize a upper surface of the piston to drive the piston lower abruptly. At the same time, the piston gives the driver connected thereto striking force.

摘要： A pressure intensifier is automatically driven repeatedly by compressed air from a compressed air source to produce highly compressed air for storage in a pressure chamber. The pressure chamber is selectively connected to or disconnected from a drive cylinder having housed therein a drive piston, under the control of a valve mechanism provided therebetween. By the actuation of the valve mechanism the highly compressed air stored in the pressure chamber is introduced into the drive cylinder to propel the drive piston, driving a nail or like fastening element into a hard receiving material such as concrete.

摘要： A fastener driving tool comprising a tool body defining a fastener drive track, a fastener driver mounted in the drive track for movement through successive drive and return strokes, a magazine providing a space for retaining a coiled strip of fasteners, a guide passage leading from the magazine to the drive track along which a leading end portion of the strip with supported fasteners can be moved, and a fastener feeding mechanism for moving the leading end portion of the strip with fasteners along the guide passage. The feeding mechanism includes a L-shaped member having a horizontally extending portion and a vertical portion extending upwardly therefrom. The L-shaped member is disposed with respect to the guide passage such that the horizontal extending portion extends through a continuous longitudinal gap in the strip and the vertically extending portion extends alongside the inner surface of the continuous wall of the strip defining the upper portion of the gap. The feeding mechanism also includes a feeding pawl mounted for movement through successive operative cycles each of which includes a feed stroke and a return stroke, and a piston and cylinder unit for effecting movement of the pawl such that the same will be engaged within one of a series of notches formed in the lower edge of the continuous wall of the strip at the end of each return stroke so that the strip will be moved with the pawl during the drive stroke thereof.
