PENCIL-SHARPENER.

SPECIFICATION forming part of Letters Patent No. 593,912, dated November 16, i897.

Application filed January 13, 1897.

pencil-Sharpeners.

The obj ect of the present invention is to irnprove the construction of pencil-Sharpeners and to provide a simple, inexpensive, and efficient device capable of rapidly sharpening a pencil and of collecting the shavings and other responding sys waste to prevent the same from accumulating upon a desk, table, or other support..

A further object of the invention is to provide a pencil-Sharpener which will be capable of supporting a pencil in proper position for sharpening it, and thereby prevent the point from being accidentally broken While it is being sharpened. Y

The invention 'consists in the construction and novel combination and arrangement of parts, hereinafter fully described, illustrated in the accompanying drawings, and pointed out in the claims hereto appended.

In the drawings, Figure 1 is a side elevation of a pencil-Sharpener constructed in accordance with this invention. Fig. 2 is a vertical sectional view of thesame. Fig. Sis a horizontal sectional view on line of Fig. 1.

Like numerals of reference designate corparts in the several figures of the drawings.

1 designates a base from which rises a vertical spindle 2, preferably formed integral with the same and receiving a tubular shank 3 of a rotary pencil-holder 4, which is provided with a head. The base may be provided with perforations for the reception of suitable fastening devices forsecuring the pencilholder to a desk, table, or other support. The spindle 2 is provided near its lower end with an annular shoulder, and it has a conical seat 6 at its upper end t0 receive a cone-bearing 7 at the top of the tubular shank 3 of the roy tary pencil-holder.

The head of the rotary pencil-holder is provided with a vertical pencil-receiving openin g or cavity 8, consisting of a cylindrical upper Serial No. 619,088. (No model.)

lindrical upper portion of thepencil-receivin g openin g or cavity 8 conforms to the coniiguration of and'is adapted to steady a pencil to prevent the point from being accidentally brokenduring the sharpening operation. The rotary pencil-holder is provided in its head with a slanting or inclined slot or opening 8a, in which is detachably mounted a knife-blade 9, and the inclined slot 0r opening communicates with 4the conical portion 'of the pencilreceiving opening to enable the bladeto engage a pencil. AThe pencil is held stationary while the holder is rotated by gearing hereinafter described, and the slanting blade, which is provided with an-inner cutting edge, gives the pencil the proper taper.

The blade 9 is provided with horizontal slots 10, and is secured to the'head of the pencilholder by means of vscrews l1 passing through the said slots and engaging threaded sockets of the head. It is adjusted by means of setscrews 12, disposed horizontally in threaded openings of lugs or projections 13 and arranged to engage the outer edge of the blade,

whereby the latter is forced inward.

The pencil-sharpener is rotated by means of beveled gear-wheels 14 and 15, mounted,

respectively, on the lower end of the tubular.

' that the parts can be thoroughly lubricated.

The shavings and other waste fall into a receptacle 18, located directly beneath the head of the rotary pencil-holder and mounted on the tubular shank thereof. The receptacle, which tapers toward its base and which is designed to be readily removable, is of a sufficient diameter at its top 'to receive'the shavings as they fall from the opening or slot 8a of the pencil-holder and effectually prevents such waste from falling upon a table, desk, or other support. v The receptacle rotates rapidly during the sharpening operation, and in order to prevent the shavings from being thrown out of it by centrifugal force it is pro- IOO vided at its upper edge with an inwardly-extending inclined rim 18a. Any suitable construction may be provided for removably mounting the receptacle on the pencil-holder.

It will be seen that the pencil-Sharpener is exceedingly simple and inexpensive in construction, that it is positive and reliable in operation, and that it is capable of rapidly sharpening a pencil and collecting the waste to prevent the latter from accumulating on a table, desk, or other support. It will also be apparent that it is adapted to steady and guide a pencil to prevent the point from being accidentally broken during the sharpening operation and that the knife-blade is capable of ready adjustment to produce the proper cut and maybe readily removed when it is necessary to sharpen it.

Changes in the form, proportion, and minor details of construction may be resorted t0 without departing from the spirit or sacrificing any of the advantages of this invention.

IVhat I claim is- 1. In a pencil-Sharpener, the combination of a base, a vertical spindle mounted thereon, a rotary pencil-holder disposed vertically and composed of an upper pencil-receiving head and a lower tubular shank arranged on the said spindle, a support rising from the base, a horizontal shaft journaled on the support,

and gearing connecting the shaft with the tubular shank, substantially as described.

2. In a pencil-Sharpener, the combination of a base, a vertical spindle rising from the base, a rotary pencil-holder having a tubular shank arranged on the spindle, a blade carried by the rotary pencil-holder and arranged to engage a pencil, a receptacle mounted on and carried by the tubular shank and arranged beneath and extending around the blade in position to receive the shavings, and gearing for rotating the pencil-holder, substantially as described.

3. In a pencil-Sharpener, the combination of a rotary pencil-holder having a pencil-receiving opening, a blade, a receptacle mounted on the pencil-holder and located below the blade, said receptacle being provided at its upper edge with an inwardly-extending rim adapted to prevent the shavings from being thrown out of the receptacle by centrifugal force, and means for rotating the pencilholder, substantially as described.

In testimony that I claim the foregoing as my own I have hereto afiixed my signature in the presence of two witnesses.
