SPECIFICATION forming part of Letters Patent No. 648,833, dated May 1, 1900.

Application filed llovemher 13, 1897. sci-in No. 658,371. No model.)

T0 all whom it may concern:

Be it known that I, EDWARD M. BENTLEY, a citizen of the United States, residing at New York, (Lawrenoe,) county of Queens, State of NewYork, have invented certain new and useful Improvements in Pencils, of which the following is a specification, reference being made to the accompanying drawings, wherein- Figures 1 and 2 represent. thetwo separate parts of my pencil, and Fig. 3 represents the article with the parts assembled.

The purpose of my invention is to provide .a pencil which shall be similar in all respects to the ordinary wooden pencil and. of equal or nearly equal oheapness, but in which the the wood'is avoided. I purpose-also that by reason of the simplicity and cheapness of my arrangement it shall be possible to regard the envelop surrounding the lead not as a permanent casing to be periodically supplied with new leads, but asa part to be thrown away in the usual manner when the lead is exhausted. Thus the inconvenience of keeping on hand a supply of leads may be avoided.

I construct the pencil of two semicircular or semihexagonal strips which have the shape of those usually employed, but are permanently pointed at their lower end, and instead of being glued together and having the lead permanently attached thereto they are separable from each-other and from the lead and are held together by external spring-clamps, one at each end and one, at least, readily removable, so that asthe lead becomes worn it is only necessary to slip OK the spring-clamp, separate the two halves slightly, and allow the lead to dropias far as desired, when the clamp the lead again held fast between the two strips. .The two strips are substantially rigid, while the clamps are yieldtheir length.

ing, so that the lead is hold firmly throughout its cntirelcngih lmtwcen the two similar still? strips.

In Fig. l, A represents one of the two strips above referred to, which is semicircular or semihcxagonal in cross-section. It is pointed at its lower cnd and centrally grooved to receive the loose load (i. In Fig. there is shown a similar strip B, while in Fig. the strips A and ii are placed side by side and held in position by a detachable spring-clamp .l) at the lower end and at the upper end by a spring-clamp E, the latter being permanently attached and, ii desired, also con tai ning a rub-- ber eraser in'thc usual way. Tiho grooves in the two strips are of such size and depth as to clamp the lead lirmly between them along As the lead 0 is consumed it is only necessary to slip oil. the clamp i), when the two parts A slight yielding of the clamp lil. This will perunit the loose lead (.3, which is shown in Fig. 1 as not extending up to the clamp E,to drop the desired distance, and the clamp D is then replaced by slipping of the pencil and the two parts thereby restored-to their normal position.

What I claim as new, and desire to secure by Letters liitent, is-
