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： 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： A mechanical pencil is disclosed in which lead feed occurs automatically upon lifting of the pencil from the paper surface or the like and in which the slider can be locked in a retreated position when the pencil is not in us. The mechanical pencil includes a tip member fitted in the front end of a shell removably, a sleeve disposed slidably in the interior of the tip member, a lead feed mechanism which is mounted in the interior of the sleeve and which permits a forward movement of a lead but inhibits a backward movement of the lead, an ejection bar mounted on the front end side of the sleeve, with the lead extending through the ejection bar, a slider disposed slidably within the tip member and having a locking engaging portion capable of engaging the tip member disengageably, the slider imparting a predetermined frictional force to the lead, and a resilient member disposed between the slider and the ejection bar, the resilient member having an urging force stronger than a lead gripping force of the lead feed mechanism under.

摘要： Mechanical pencil in which a chuck assembly for gripping a lead is formed with plural chuck elements mutually combined with each other. The chuck assembly has an internal longitudinal hole to insert a lead through and a lead gripping portion to grip the lead, while a lead guide tube is movably inserted within the lead inserting hole. The lead guide tube pushes on acting portions of the chuck to open the gripping portions of the chuck elements in the direction of parting them from each other when the lead guide tube is advanced, and the lead gripping portion opens to release the lead. The chuck is designed to enable releasing and gripping the lead securely so that it can be suitably used as a chuck mechanism for extending the lead automatically.

摘要： A propelling or automatic writing implement having a lead which can be projected from the implement without pushing. An inner frame having a chuck assembly for permitting advance of the lead but preventing retraction of the lead and a lead protecting tube having a holder for holding the lead with a suitable frictional force are housed in a main body and slidable axially thereof. A mechanism is provided for retracting the frame and the tube by a reaction to which the lead is subjected when pressed against the writing surface with a force of considerable magnitude and for returning them when the lead is released from the force, while permitting the tube to move backward and forward relative to the frame in the course of the reciprocating movement. The lead can be projected by the relative movement of the tube and the frame.

摘要： An automatic pencil employing axial movement of a lead piece guide and a lead piece chucking mechanism. After a length of protruding lead rod is used up, the lead piece guide is caused to retract in the same amount as the wearing away of the lead rod. By pressing the tip of the lead rod against another object, the lead rod is caused to move back with the chucking mechanism. After the rod is retracted until the tip aligns with the tip of the guide, the rod and lead piece guide will be moved back. The rod will then advance when the holder is moved away from the object while the lead piece guide will be left in the retracted position due to a large friction between the friction member and the guide means. By this operation, the rod is protruded from the guide at substantially equal length to the stroke of the retracting movement. In other words, the guide is moved back at each time when the rod moves back and forward to allow the rod to protrude by a constant length which is irrespective to that which has previously protruded.
摘要翻译：一种铅笔引导件和引线片夹持机构的轴向运动的自动铅笔。在使用一段突出的引线杆之后，引线引导件以与引线的磨损相同的量退回。通过将引线的尖端压靠在另一个物体上，引导杆通过夹紧机构向后移动。在杆缩回直到尖端与引导件的尖端对准之后，杆和引导件引导件将被移回。当保持器从物体移开时，由于摩擦构件和导向装置之间的大的摩擦，引导件引导件将被留在缩回位置，所以杆将会前进。通过该操作，杆从引导件以与收回运动的行程基本相等的长度突出。换句话说，当杆向后和向前移动时，引导件向后移动，以允许杆突出一定长度，这与先前突出的杆不同。
