COMBINATION PENCIL rno'rnc'ron Ann SHARPENER.

Specification of Letters Patent. Application filed August 20,

To all whom it may concern:

Be it known that I, THOMAS GOODAIR, of the city of Winnipeg, in the Province of Manitoba, Canada, have invented certain new and useful Improvements in Combination Pencil Protectors and Sharpeners, of which the following is the specification.

My. invention relates to combination pencil protectors and sharpeners and the object of the invention is to provide a simple and inexpensive device which can be readily attached to any encil when it is being carried, thus servingt e purpose of protecting the pencil point from breakage and which can be utilized for sharpening the pencil if it be so desired.

It consists essentially in a short tubular member, the oneend of which is open and the other end of which is tapered conically to a point, there being openings formed in the conical end 'bypiercing the material inwardly; .the parts being arranged and constructed as hereinafter more particularly de- Figure 1 is an enlarged detailed perspective view of an embodiment of the comblnation pencil protector an'dsharpener. Fig. 2 is a vertical cross sectional view through the In the drawings like characters of refer- ?ince indicate corresponding parts in each gure.

2 represents the combination protector and shar ener which is formed from a tubular mem er 3, designed to pass over the end of the pencil. In order that the device may hold firmly to the pencil it is provided'with the usualslits 4., formed in the tubular portion and extendin longitudinal of it. The one end of the tu e'is tapered conically at 5," there being a slight o ening 6 left at the apex of the cone throng which the lead of t e pencil can pass centrally.

such openings appearing at intervals over the complete surface. The edges of the Patented Feb. 1, 1910.

pierced openings are turned inwardly and form a series of cutting pointswhich serve to sharpen the pencil.

As shown, the tapered end 5 is provided with a series of adjoining longitudinal chan nels 9 having common bounding edges and 11, as best shown in Fig. 2; The open" ings 8 are formed Within the depressed por tions of the tapering end. It will be seen that the tapering end produces a gripping surface. It will also be noticed that this method of construction leaves a clearance at 12 for the material removed from the pencil between the adjoining longitudinal rows of openings.

I wish it to be understood that the openings may be of any shape which it may be found. advantageous to have in order to give the best resu in the drawn s being circular. In usin the device it is simply placed on the penc and turned, the inwardly directed edges of the openings shaving or scraping the material of the pencil, thereby bringing it to a conical'point.

' What I claim as my invention is:

A edmbination pencil rotector and sharpener comprising a tubu ar member adapted to fit oventhe end of a pencil, and a tapering end piece to the tubular member having a'series of longitudinal depressed channels and openings formed in the'depressed portion of the channels, said openings having inwardly directing edge portions.
