SPECIFICATION forming part of Letters Patent No. 606,036, dated June 21, 1898.

Application filed September 16, 189 '7. Serial No. 651,894. (No model.)

To'aZZ whom, it may concern:

Be it known that I, LOUIS STOEOKER, a citizen of the United States, residing at J ersey. City, in the county of Hudson and State of New Jersey, have invented certainnew and useful Improvements in IencihSharpeners, of which the following is a specification.

This invention relates to an improved pencil-sharpener that can be manufactured at a very cheap price, so as to be used by schoolchildren, and by which the cutting of the wood and lead is accomplished in a regular and uniform manner, so that a nice tapering point is obtained; and the invention consists of a pencil-sharpener comprising a handle -frame provided with an enlarged end portion and with spring-arms diverging from said end portion and provided with slits or sockets in their upper and outer ends, and a cuttingblade sprung into saidsockets and having the cutting edge directed toward the apex of the spring-arms, the space between said arms forming a gage-for cutting a point of proper length, as will be more fully described hereinafter and finally pointedout in the claim.

In the accompanying drawings, Figures 1 and 2 are views in perspective of myimproved pencil-sharpener in use. Fig. 3 is a top View of the sharpener, showing the cutting-blade removed. Fig. 4 is a detail showing in section one of the arms. Fig. 5 is a section on line 5 5, Fig. 3. Fig. 6 is a similar View showing the cutting-blade in position, and Fig. 7.

is a sectional view of the cutting-blade.

Similar letters of reference indicate corresponding parts.

In the drawings, A represents the handleframe of my improved pencil-sharpener,which is constructed of any suitable spring metal. The handle-frame comprises an end portion a, formed by doubling the metal at the center, and two diverging spring-arms a of any suitable length and shape. The end portion a is preferably enlarged at the end, as shown, so as to provide a means for easily grasping the same. Near the extremity of the springarms a is secured the cutting-blade B, which consists of a thin plate of tempered steel hav ing its beveled cutting edge in the direction of the handle. Suitable slits or sockets b are provided in the upper and outer ends of the spring-arms a, into which the ends of the blade B are inserted. The blade "B is made of such'a length that when inserted in the tapering pencil-point obtained by successively turning the pencil and subjecting the point to the action of the cutting-blade, care being taken that the lead abuts before the cutting action against the apex formed by the diverging spring-arms. The diverging springarms press firmly against the ends of the cutting-blade, thus securely holding the cuttingblade in the slits or sockets b, from which it may be readily removed for sharpening. The cutting-blade is preferably located at the extremity of the arms a and near one edge thereof, as shown in the drawings. The sockets are preferably slightly inclined, giving a corresponding inclination to the cuttingblade.

In operation thepencil to be sharpened is held inthe left hand. The sharpener is then grasped by the fingers of the right hand, with the cutting-blade at the upper edge and the point of the pencil inserted between the spring-arms until the lead abuts against the apex of the diverging spring-arms and the cut ting-blade rests upon the portion of the pencil from which the cutting is to begin. The sharpener is then drawn toward the point of the pencil, and the cutting-blade removes a shaving after the manner of a drawing-tool. The pencil is then turned and the cutting action continued successively until a nice point is obtained. I

My improved sharpener is simple in construction, compact and convenient in shape, and'can be manufactured at little cost. The cuttiagblade is so located as to be readily sharpened and can also be easily removed and claim as new and desire to secure by Letters Patent- A pencilsharpener, consisting of a handleframe having an enlarged handle portion and spring-arms diverging therefrom, a cuttingblade sprungin between said spring-arms and having its ends seated in sockets at the outer ends of said arms and its cutting edge toward the handle portion, and a gage for regulating 10 the length of the out, said gage being formed by said spring-ar1ns between the blade and handle portion, substantially as set forth.

In testimony that I claim the foregoing as my invention I have signed my name in presence of two subscribing Witnesses.
