摘要： An improved propelling pencil is provided of which lead can be projected or exposed to a predetermined amount by applying writing pressure to a pencil cyclinder, when the lead is worn out or broken. According to the invention, the pencil is free from breaking of the lead due to excessive projection of the lead from the pencil body.

摘要： An automatic mechanical pencil has a tubular piece removably connected to a barrel cylinder, and a slider for frictionally holding a lead and being movably disposed in a front portion of the tubular piece. A lead chuck is disposed in the barrel cylinder for releasably holding the lead so as to allow forward movement of the lead but prevent backward movement thereof. A first spring urges the slider forward and the lead chuck backward so that when a writing front end of the writing instrument is released from a writing surface, the lead is automatically fed by urging the slider forward. A lead reservoir is disposed rearwardly of the lead chuck to supply the lead to the lead chuck. The lead reservoir has a reservoir main body, a pipe holder connected to a front end of the reservoir main body and having a guide projection, and a stopper disposed around an outer periphery of the pipe holder and having a receiving groove engageable with the guide projection. A second spring urges the reservoir main body and the stopper of the lead reservoir so that the reservoir main body and the stopper move relatively in the axial direction of the barrel cylinder.

摘要： A mechanical pencil having a chuck mechanism which permits the lead to advance but prevents the lead from retracting, a first slider, a second slider which is retractable progressively as a writing pressure is applied, a first engagement device for holding the second slider at its retracted position and a second engagement device for holding the first slider at its retracted position. The progressively retracted second slider is released to advance to the forward original position by applying a further writing pressure to cause a retraction of the first slider. Then, the second slider is advanced forwardly together with the lead so that the lead is advanced to a writing position.

摘要： A mechanical pencil having a writing point tube slidably mounted on the forward end portion of a pencil casing, an annular slider device slidably mounted within the pencil casing and having a lead retainer, a first spring for urging the writing point tube in the forward direction, a collet chuck mechanism having a lead engaging collet and a chuck-actuation cylinder, a second spring urging both the lead engaging collet and the chuck-actuation cylinder in the opposite direction and a third spring for urging the collet chuck mechanism in the forward direction. The pencil has a locking device for temporarily engaging the slider at its retracted position, and a pusher for releasing the engagement of the slider. When an axial thrust is applied to the writing tip of the pencil for lead advancement, the slider and the collet chuck mechanism as well are retracted within the pencil casing with their positional relation being unchanged. When the thrust against the writing tip is released, the collet chuck mechanism is advanced at first with the lead grasped therein to feed the lead out of the lead tube while the slider is temporarily engaged at its retracted position, and thereafter the pusher abuts against the slider to unlock it so that the slider advances by the effect of the first spring with the lead projecting from the lead tube.
摘要翻译：一种自动铅笔，其具有可滑动地安装在铅笔壳体的前端部的书写点管，可滑动地安装在铅笔外壳内并具有引线保持器的环形滑动装置，用于向前方推压书写点管的第一弹簧，具有引线接合夹头和卡盘驱动筒的夹头卡盘机构，沿着相反方向推动引线接合夹头和卡盘致动筒的第二弹簧，以及用于向前推动夹头卡盘机构的第三弹簧。铅笔具有用于在其缩回位置暂时接合滑块的锁定装置和用于释放滑块的接合的推动器。当向铅笔的笔尖施加轴向推力时，滑块和夹头卡盘机构也以其位置关系不变而缩回到铅笔盒内。当释放写入尖端的推力时，夹头卡盘机构首先被夹在其中的引线推进，以便当滑块临时接合在其缩回位置时将引线从引线导出，然后推动器抵靠滑块以将其解锁，使得滑块通过第一弹簧的作用而前进，其中铅从引导管突出。

摘要： A tip-pushed type mechanical pencil permits a forward advance of a pencil lead by pressing the front end of the pencil against a writing surface and then releasing it. The mechanical pencil includes an outer cylinder in which an inner cylinder having a ferrule is fitted. The inner cylinder is normally urged by a first spring to cause the ferrule to project out of the front end of the outer cylinder. A control tube carrying a lead grasping packing is inserted within the inner cylinder. The control tube is urged toward the front end of the outer cylinder by a second spring. A chuck is received within the control tube, and is integrally connected with a lead passage tube which extends through the inner cylinder. The chuck cooperates with a chuck ring disposed within the control tube to grasp or release a lead. Both the chuck and the control tube are urged by a third spring in opposite directions. When the ferrule is pressed inward against the resilience of the first spring, the control tube retracts together with the inner cylinder, and when the force applied to the ferrule is released, the control tube moves toward the front end in delayed relationship with respect to the movement of the inner cylinder.
摘要翻译：尖头式自动铅笔允许通过将铅笔的前端压靠在书写表面上然后将其释放而使铅笔线的前进。该自动铅笔包括其中装配有套圈的内筒的外筒。内筒通常由第一弹簧推动以使套圈从外筒的前端突出。在内筒内插入带有把持填料的控制管。控制管被第二弹簧推向外筒的前端。卡盘被容纳在控制管内，并且与通过内筒延伸的引导通道管一体连接。卡盘与设置在控制管内的卡盘配合以抓住或释放引线。卡盘和控制管均由相反方向的第三弹簧推动。当套筒内侧抵抗第一弹簧的弹力而向内压入时，控制管与内筒一起缩回，并且当施加到套圈的力被释放时，控制管以相对于第二弹簧的延迟关系向前端移动内筒的运动。
