Description
W, BARCLAY SHARPENER CA1? May 1 5, 1934.
Filed March 16, 1933 Patented May 15, 1934 UNITED STATES PATENT OFFICE 1 Claim.
The object of the invention is to provide a pencil sharpener that may be incorporated in a cap in which the dimensions of the cap are only very slightly increased as compared with a normal pencil cap.
Another object is to provide a sharpener for pencils, or the like, which may be carried with a pencil and in which the pencil may readily be removed and replaced.
Another object is to provide a sharpener for pencils, or the like, which may also be used to protect the point of the pencil when the pencil is not in use.
Other features and advantages of the invention will appear from the following description taken in connection with the drawing, wherein:
Figure 1 is a front view of the cap with a pencil held therein.
Figure 2 is a side elevation of the cap shown in Figure 1.
Figure 3 is a cross section thru the device showing a pencil therein.
Figure 4 is a front view of the upper portion of the cap with the front surface of the cap removed showing the eraser and sharpening device.
Figure 5 is a cross section on line 5-5 of Figure 3 with the pencil removed showing the sharpening device.
Figure 6 is a detail showing a spring clip for holding the eraser in the device.
Figure 7 is a detail showing a method of locating a spring clip in the upper end of the cap.
Figure 8 is a View showing a spring clip similar to that shown in Figure 6 with the indentations or projections omitted.
In the drawing the device is shown as it would be made wherein numeral 1 indicates the cap, numeral 2 the sharpener, and numeral 3 the eraser.
The cap 1 may be of any type or design and may be made for a pencil of any size or description, may be made of any material and may be mounted upon the pencil in any manner or by any means. In the design shown the cap 1 is provided with a compartment4 in which the sharpener 2 is installed, an upper extension 5 in which the eraser may be held, and another extension 6 at the opposite end in which a pencil, or the like, may be held. In the design shown the compartment 4 is of a rectangular shape with the corners rounded, as shown in Figure 5, and the sharpener 2 is placed therein from the lower end and then the lower end crimped together over a circular sleeve '7, which forms the lower extension 6, thereby forming a bead 8 at the upper end of the sleeve '7. The lower edges of the sleeve 7 may be slightly rolled or curved outward to form a bead 9, as shown in Figure 3, in order to facilitate placing a pencil therein. This sleeve may also be provided with a slit- 10 to permit it to spread and also to allow for a certain amount of spring so that it may grip and hold a pencil therein. It will be understood that the extension 6 may be of any other shape and may be formed in any other manner.
The sharpener 2 may also be formed of a rectangular shaped piece of material, as shown in Figure 5, and this may have a conical opening 11 therein corresponding with the end of a pencil, and a knife blade 12 may be held in a recess 13 at one side by a screw 14. This knife is also held by the walls of the compartment 4. t will be understood, however, that the sharpener may be of any other type or design and any other type of blade may be used and the blade may be held therein by any other means. The sharpener may also be mounted or held in the cap in any other manner or by any other means.
The eraser 3 is held in the extension 5 at the upper end of the cap by a spring clip 15 and this clip is provided with indentations 16, the metal from which projects inward forming points 1'7, which are shown on an enlarged scale in Figure 7, and these points will be pressed into the rubber to locate and hold the rubber from the center thereof. The surfaces of the extension 5 are also provided with indentations 18, that correspond with the indentations 16, as shown in Figure 7, and these locate and hold the clip in the extension. The upper ends of the spring clip are curved slightly over, as indicated by the numeral 19, to provide gripping means by which the clip may be pressed together and withdrawn with the eraser. It will be noted that as the eraser is used the clip may be withdrawn and the eraser moved upward therein so that the points 17 will grip the eraser at lower points and then the clip with the eraser replaced in the upper end of the cap. This makes it possible to readily adjust the eraser or move it outward as it is used. It will be understood, however, that any other means may be used for holding the eraser in the clip.
It will be understood that other changes may be made in the construction without departing from the spirit of the invention. One of which changes may be in the shape or size of the eraser, another may be in the use of other means for forming the eraser section on the cap or in the location or position thereof, another may be in the relative positions of the eraser, sharpener and holding sleeve at the lower end of the cap, and still another may be in the use of a sharpener of any other type in combination with a pencil cap.
The construction will be readily understood from the foregoing description. In use the cap may be provided as shown and described and it will be noted that it may normally be carried upon the upper end of the pencil and, wh'en it is desired to sharpen the point, the pencil may be withdrawn and reversed so that the point will extend into the cap. The pencil may then be turned and, as it is turned, the cutting blade will sharpen the pencil, as shown in Figure '3. The pencil may then be withdrawn and the opposite end inserted in the cap so that it maybe 'usedas desired. When it is desired weaver the point of the pencil, the pencil may also be withdrawn and the point inserted in the cap as it willbe notedthat with the point inserted in the cap it will be protected the same as if anyother cap were used. It will alsobe noted that the eraser may be removed and adjusted and renewed as may be desired. v ,7 r W It is preferred to use the cap without a pencil clip, however, it will be noted that a pencil clip mayibe placed upon the cap, as indicated by the numeral 20 and shown in Figure 2 if desired, and this clip may be of any type or design and may be located at any other point or points on the cap or on any part thereof p Y The clip 15 has been referred to as 'a springs lip however, it will be understood that it is not nec- 'essarily made of spring material as it ma be made of any material and held in place by the indentations and projections. This clip may, however, be made of spring material and the indentations and projections omitted, as shown in Figure 8, as it will be noted that a. slight spring in the material, in combination with the eraser, will resiliently hold the clip in the cap and also the eraser in the clip. In this case the clip may be made the full width of the extension 5 so that it will fit snugly-in the cap and thereby eliminate lateral movement or playof the eraser. It will also be understood that the clip may be made of'any'material and of any type or design.
Having thus fully described the invention what I claim as new and desire to secure by Letters Pat- A pencil sharpener cap comprising a block said lolol z'r'if rectangular cross section providing 'the leiig't h thereof, and said block having a conia sh ped n i pa t ev ni there n! rev le .o em m n isid e ai ethic l d e n' f kni b ad po i i ed e d l jw t blitt ns e the e lsat ed "Slightly T conical opening at one side of said outlet opening, a screw positioned midway of saidblade threaded into said block adapted to hold said "blade firmly in saidseatpand'a housing forming apescil cap enclosing'said'lolo'ck'and knife coveri g said screw and engaging thesiirfac'e'of said'lini'fe and adapted tojbe removablyheld uponapenoil, said housing having an "outlet opening horrespondingwiththat er the block, andf'with the side in which the opening is formed incliiiedinw'ard toward the uppenendthefeoi. 1 i
