, conuex longitudinally and the bars themselves Fig. 10 is abottom view of the rotary latchof being curved, accordingly for guidance along {1n iliiniciil i? curvedpaths.

Owing to its truly axial alignment, the tubular element 9 will be firmly held by the muzzle II, when projecting therethrough, without any objectionable lost motion.

While in the embodiment shown in Fig. 1, the casing I is illustrated as extending over the core 2 up to the top thereof being provided with slots 25 affording the required freedom of movement to the actuating bars 6, I may modify the design by terminating the casing l at the line 26 shown in Fig. 2 thus leaving the upper section of core 2 bare. In this modification, casing I need not;

be provided with any slots. In either case the core may have a pressed lit in the casing 'l. to

save the cost of additionalconnecting means.

The core 2 has an axial bore l1 dimensioned from the casing I.

embody the same principle in pencils having two,

three, five or more lead-holders.

to render it fit for the accommodation of. reserve leads H. The upper end of the core 2. has. ex-

ternal threads and a shoulder ailordin'ga seatfor the upper off-set extension 4 of a clip held "in position by a knob 5. A cap-3 screwed on the core member 2 constitutes a cover of the magazine I'l'.

Helical springs I I having their lower ends attached to the lead-holders and their upper ends to a spider 12 attached to the core 2 by an axial bolt 2? serve to keep the lead-holders in the rest ing position in which their upper ends engage member 4. a

I shall now describe another important feature of my invention same being the provision 01'. new and simplified means for arresting any leadholder in its projected position shown in Fig. '7 once it has been manually shifted thereto.

Rotatably mounted on the lower end of the axial bolt 21 projecting from the core member 2, there is a star shaped latch 13 having upturned arms provided with slanting edges as shown in Fig. 9. Notches l8. are formed between the arms. This latch I3 is normally held in'the position shown in Fig. 9 by a U -shaped leaf spring it which is encased within a cavity provided in the bottom of the core member 2 and has one of its arms projecting downwardly through a hole 28 (Figs. 1 and 10) in member 13. This spring is so mounted as to urge its extended armintocontact with the left hand wall of the cavity as shown in Fig. 9. This arm, however, mayizne deflected by an oscillation of the latch 13 about the axial bolt 21 into a position indicated in Fig.

9 by dotted lines. The radial arms oi. the latch ing bars For, more specifically, into the path of downwardly facing shoulders 29 provided in said arms by inner recesses l5 therein; when one of the actuating bars 6 is shifted downwardly by manual actuation of its knob 1'8, its shoulder 29 engages the face of the slanting edge thus oscillating the latch 13 until the bar 6 isdisposed in a notch [8. Continued downward motion of the bar 6 brings an upwardly facing shoulder 30 thereof beneath the latch 13. When this happens, latch I3 will be re-set to its initial position by the spring 16 and will consequently lock and arrest the lowered bar 6 upon manual release of the latter. The shoulder 30 is provided by another inner recess [5 of each bar 6.

It will be appreciated that theoscillation ofthe star-shaped latch i 3 by engagement thereof'with the shoulder 29 of any selected lead-holder-will cause the coincidental release of any previously arrested lead-holders by the sliding of shoulder to thereof along slanting edge 44 into notch l8 and the consequent return thereof by its spring ii to resting position. (7 v i 3 extend normally into the paths of the actuat- Moreover, I wish it to be clearly understood that my invention is in no way limited to the details shown in the drawings and described herein above but is capable of numerous modifications within the scope of the appended claims.
