From this base, admit one of larger diameter. On this hollow near one end, rise the uprights or standards B, shaft and designed to move therewith betwo in number, and in which is journaled in tween the upright portions of the yoke is the suitable bearings the shaft 0, carrying the hub or pulley J, which is preferably con- 50 wheel D, which is designed to revolve between caved, as seen in both views, to prevent dis- I00 placement of the belt or band K, (preferably elastic,) which passes over the said pulleys G J, as shown.

L is a guard rising from the base, and at its upper end, which is arranged slightly above the upper faces of the pulleys, it is provided with a cross-bar 7a, the belt or band passing through between the upright portions of the guards, as seen best in Fig. 1.

YVith the parts thus constructed the operation is apparent and is as follows: A pencil Z is placed in the holder, where it is firmly clasped by the spring-arms at each end thereof, the pencil being pushed through the holder sufficiently far for its point to come in contact with the emery I) on the face of the wheel D, as seen in both views. The handle 0 is then turned, which imparts motion to the wheel D, and this in turn, through the friction-wheel F, shaft F, pulleys G and J, and band or belt K, revolves the pencil, so as to give it a uniform temper and finish. The manipulation of the standard H presents the point or end of the pencil at different angles to give the required point thereto. The guard, together with the concave pulleys, prevents displacement of the band or belt when the holder is turned in the different positions.

Vhat I claim as new is 1. The combination, with the wheel and the friction-roller arranged to move in contact therewith, of the rotatable standard, the pencil-holder carried thereby, a shaft parallel with the holder and receiving its motion direct from the wheel,and a band for revolving the said holder from said friction-roller, as set forth.

2. The combination, with the rotary wheel, of the rotatable standard, a revoluble pencilholder, a pulley mounted to revolve therewith, and a band passed over the said pulley and receiving its motion from the rotary wheel through intermediate frictional devices, as set forth.

3. In a pencil-sharpener, the combination, with the rotatable standard, of a yoke thereon, a hollow shaft reinovably journaled in the upright portions of the yoke and having spring portions at the ends, a pulley mounted to revolve with said shaft, a revoluble wheel, and intermediate connections between the wheel and the said pulley, substantially as specified.

In testimony whereof I affix mysignature in presence of two witnesses.
