y To all whom it may concern:

Be it known that I, PAUL E. WIRT, of Bloomsburg, county of Columbia, and State of Pennsylvania, have invented a new and useful Improvement in Pencils, of which the following is a specification.

My invention relates` to that class of pencils in which separate points are removably inserted and held inastock, barrel, or holder, to be replaced, when worn out, by new points. The invention consists primarily in a tubular stock or holderpwhich serves as a reservoir for a supply of points, a removable pointsection for holding the points, and a holding device projecting into the point-section'.

The invention also consists in the details of construction and combination of parts hereinafter described and claimed.

In the accompanying drawings, Figure l represents a longitudinal section through the pencil; Fig. 2, a perspective view of the stock or holder with the point-section removed. Fig. 3 is a perspective view of the point-section. Fig. 4 is a longitudinal section of a slightly-modified construction. Fig. 5 is a similar View of another medication.

Referring to the drawings, a designates a tubular stock or barrel of any suitable or preferred size or shape. As represented in Fig.

1, the tubular bore extends entirely through' from end to end, the outer end being closed by a plug or stopper b, which is preferably made of rubber adapted to be used as an eraser. When the eraser is not desired, the bore need not extend through the outer end. The front end of the stock is exteriorlyscrewthreaded, as shown at d', for the reception of.-

the interiorly screw-threaded point-section c, and it has at one side a forwardly-projecting arm-a2, the purpose of which will be presently explained. This arr'n may be made integral with the stock, as represented in Figs. l and 2, or it may be made of aseparate piece ofV wire soldered or otherwise secured within the front end of the stock, as represented in Fig. 4. The point-section c is made in the shape of a hollow cone, its larger end or base being interiorly screw-threaded-for the reception of the front end of the stock a, and the opening in the frontend of a size to suit the points t0 be used therewith. Both the stock aand the point-section c may be made of any .suitable or preferred material-as, vfor example, of wood, celluloid, hard rubber, metal, glass, paper, or pulp '-according tothe Iinish desired 55 or the particular use to which thepencil is to be applied. 1

d designates the pencil-points, which, as represented in the drawings, are made in the shape of small cones of uniform sizes, ac- 6ocording to the size 'andvstyle 0f pencil for which they are made, and so proportioned that they will project beyond the end of the point-section c far enough to present a desir able and convenient pencil-point, the base 65 being largerpthan the opening in the pointsection to prevent'thern from passing entirely through. The points are made of any suitable material, according to the uses for which they are intended.

As represented in the drawings, the stock a, forms a reservoir in which a supply ot' points is conveniently stored and carried and from which new pointsarel taken from time to time, as required for use. 7 The relations of the parts thus far referred to are shown in Figs. l and 4. The point CZ having been introduced into the point-section c and the latter screwed upon the end of the stock a, the arm a2 projects'forward within 8o the point-section and bears against the base of the point and holds the same in position, it being of course understood that the length of the arm is such that it will just reach the base of the point when the pointlsection is 85` screwed home to its place on thevstock.

When the point d is worn out or worn down tosuch an extent that it is desired to replace it with a new one, thepoint-sectio'n is taken 0H, the butt of the old or worn point is 9o removed therefrom, a new point is taken from the reservoir and inserted in vthe point-section, and the latter is then screwed back in place, when the pencil is again ready for use.

Referring now particularly to the construction illustrated in Fig. 5, it will be seen that the arm a2 is omitted, and that I use in place thereof a loose block d3, of suitable size and length to fit loosely within the point-section c, and to bear at one end against the end'ot Ioo the stock a and at the other against the base of the point d, when the point-section is screwed in place; There is no difference in function between the block a3 and the arm c?,

the only dilerence in construction being that the one lies loosely in the point-section c, while the other is attached to the stock.

Having now described my invention, what I claim is- 1. In a pencil, the combination of the hollow stock,adapted to receive a number ot points,the hollowr point-section removablyattached to the end of the stock, and a holding device projecting forward from the stock and beyond the same into the point-section to hold the point'in place.

2. In a pencil, the combination of the hollow stock, adapted to receive a number of points, the hollow conical point-section removably attached to the end of the stock, the

' conical point in said point-section, and a holding or retaining device extending beyond the stock between the same and the points to hold the latter in place.

3. In a pencil, the combination of the hollow stock, adapted to receive a number of points, having the forwardly-projecting arm o?, the conical hollow removable point'section 5. In a pencil the combination of the stock,`

adapted to receive a number of points, the hollow point section removably attached to the end of the stock, and a holding device projecting beyond the stock and into the point section to hold the points in place.

In testimony whereof I hereunto set my hand this 30th day of November, 1894, in the presence of two attesting witnesses.
