AUTOMATIC HOLDER FOR PENCIL-LEADS.

SPECIFICATION forming part of Letters Patent No. 394,016, dated December 4, 1888.

Application filed July 27,1888. Serial No. 281,197. (No model.)

To aZZ whom it may concern: a series of notches or ratchet-teeth, b. The Be it known that I, GUSTAF R. SANDELL, of tube 15 is detachably secured in the sheath in the city, county, and State of New York, have order to permit it to be withdmwn, together invented a new and useful Improvement in with the pencil movement which it contains, Automatic Holders forPencil-Leads, Crayons, when ever it is desired to renew or replace the 5 5 and other Articles, of which the following is lead. For this purpose it is thus secured in a specification. the present instance by causing its front end My invention, relates to that kind of an auto take a bearing and to be centered in the tomatic holder in which the lead is autoi'natifront end of the sheath, and by providing it callyprotruded and locked or relez ed and nearits rear end witha circumferential flange, 60 withdrawn according as the holder is held (3, which bears upon the rear end of the sheath. point upward or downward, being for this A removable cap, A, fitting closely over and purpose provided with gravity or self-locking down on the sheath and the tube, holds the and releasing mechanism, which causes the latter firmly in position. At the same time looking or releasing of the lead-carrier acwhenever the cap taken off, the tube B and 65 cording to the position of the holder. Such a its contents can readily be removed from the holder, broadly considered, not of my insheath. vention, and is not claimed by me. In the Freely sliding within the tube ll is the leadholder which I have devised the carrier freely carrier I), provided with an inclined tooth, d, y sliding within prescribed limits is capable of which projects into the slot (1 and is designed 70 i a partial movement of rotation to bring a pin, to engage any one of the notches 71. In order i tooth, or detent on it into and out of en gageto confine the movement of the carrier within t ment with a notch or notches in one edge of limits which willinsure the properprotrusion a slot in which the detent moves, and it is and withdrawal of thelead, it is provided with 2 5 actuated to so engage the notch by means of two shoulders, 6, between which is the stop f, 7 5 an independently-movable follower provided which in this instance is a ring within and with an inclined or otherwise suitably formed connected to the tube 13 and loosely encircling face, which strikes the carrier and turns it far the carrier. enough to bring its tooth into engagement In order to permit the carrier to be adwith the notch. I desire it to be understood vaneed, so as to compensate for the wear of So at the outset, however, that I do not claim, the lead, the stop-ringismade movable lengthbroadly, this last-mentioned feature. It is wise of the tube B. For this purpose it fits not of my invention. the tube with enough friction to be held firmly My invention resides in the particular comto whatever position it may be brought, and

3 5 bination and arrangement of instrumentaliyet to be moved by hand from one position to 85 ties, hereinafter set forth, which have been another. For instance, by pulling on the lead devised by me for the purpose, and these can the ring by the rear shoulder P will be adbest be explained and understood by reference vaneed, and by pushing back the lead the to the accompanying drawings, in which ring by the front shoulder 6 will be caused to Figure 1 a longitudinal axial section of recede. The best adjustment to preserve is 90 the holder with the lead projected. Fig. 2 is that in which the point of the lead is just a plan of the slotted tube and parts carried flush with the front end of the pencil-tip when by the same, with the lead projected. Fig. 3 the carrier is in retracted position. is a like view of the same parts with the lead The tube B contains also the weighted folretracted. Fig. 4 is a plan of the follower. lower E, which is freely movable therein 1011- 5 Fig. 5 is a plan of the carrier. gitudinally independently of the carrier D.

A is the tubular sheath or handle of the For convenience sake, and asameans of guidholder, within which is secured (preferably ing the follower and of limiting its independdetachably) the tube 13, longitudinally slotted ent movement, its front end loosely encircles at a, and having along one edge of the slota at g the carrier in advance of the tooth d. It too is provided some distance back of the ring 9 with an inclined or slanting face, h, which also is intended to act in conjunction with tooth d. The distance between ring (1 and the part h determines the extent of the independent movement of the follower. The follower is capable only of sliding movement, and is prevented from rotating in tube 1) by longitudinal fins 1'- on it, which bear against the opposite longitudinal edges of the slot a.

Such being the construction, the mode of operation is as follows: \Vhen the pencil is held point downward, the carrier will drop as far as permitted by the stop f. As it brings up against this stop, the follower, which. is moving on behind it, strikes with its incline h the carrier-tooth (l and gives to the carrier a slight movement of rotation sufficient to bring the tooth d into engagement with that one of the notches Z) opposite which it may happen to be. In this way the carrier willbe locked with its lead protruded so long as the pencil is point downward. As soon, however, as the pencil is turned the other way, the follower will fall away from the carrier, which then releases the slight hold of its tooth cl upon the ratchet side of the tube and drops back until its front shoulder 6 brings up against the stop fiat which time the point of the lead should be withdrawn into the sheath.

Under the arrangement above described it will be noted that the carrier and its self locking and releasing mechanism are adjustable bodily and together within the tube or casein which they are contained, and, further, that the said tube, with its contents, is removable from the sheath or handle.

Having described my invention, I state my claims as follows:

1. In an automatic holder, the combination, with the sheath or handle, of a longitudinally-slotted tube or case within said sheath, and a lead-carrier and self locking and releasing mechanism therefor adjustable bodily and together within said tube.

2. The combination, with the sheath or handle, of the longitudinallyslotted case con tained within and removable from said handle, and. the lead-carrier and its self locking and releasing mechanism adjustable bodily and together within said tube, substantially as and for the purposes hereinbefore set forth.

The sheath, the longitudinally slotted and notched tube or case within the same, and the carrier freely movable by gravity within prescribed limits in said case and provided with a tooth to engage one of said notches and with stop-shoulders, as described, of a longitudinally-adjustable stop carried by the said tube or case and a follower provided with a face to act upon the tooth of the carrier, substantially as and for the purposes hereinbefore set forth.

4. The combination of the sheath A, the removable tube B, the cap A, the carrier D, the follower E, and the adjustable stop f, all constructed and arranged for joint operation, substantially as and for the purposes hereinbefore set forth.

In testimony whereof I have hereunto set my hand this 25th day of July, 1888.

GUSTAF R. SANDELL.
