JOSEPH ANDERSON, OF SAN DIEGO, CALIFORNIA.

PENCIL-SHARPENER.

Specification of Letters Patent.

Patented Sept. 6, 1910.

Application filed March 20, 1909. Serial No. 484,716.

To all whom it may concern:

Be it known that I, Josnrrr ANDERSON, a citizen of the United States, residing at San Diego, in the county of San Diego and State of California, have invented certain new and useful Improvements in Pencil-Sharpeners, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to a cutting device of the type adapted to point or taper the end of articles and is more especially clesigned for the sharpening of pencils or the like. Most of the prior tools along this line with which I am familiar have been more or less defective or objectionable in practice, owing to their complexity and the frequent adjustment necessary to keep them in proper order, and it is one of the objects of the present invention to provide a tool for the purpose stated, which is simple in construction, cheap to manufacture, and at the same time, owing to the peculiar construction and arrangement of parts, possessing the advantages of efficiency in operation.

It is contemplated to provide a tool which is portable in character and by reason of the possible minuteness of the article owing to the few number of parts, the device may be carried in the pocket, andto this end a protecting casing which may constitute the body part of the implement, is provided and which casing is free from protuberances, since such of the operating parts as proj ect beyond the inclosing casing in the operation of the tool may be collapsed and occupy a position fiat against the side walls of the casing when the tool is not in use.

Again, the tool is of a character making it susceptible for use as a pencil holder and with this in View retaining means may be provided for attaching the same to the apparel of the user.

Novel details of construction and arrangement of parts will be specifically referred to hereinafter in the description, which for a correct interpretation thereof should be considered in connection with the accompanying drawings forming a part hereof and wherein satisfactory embodiments of the invention are disclosed, for the purpose of illustration.

In the drawings, Figure 1 is a perspective view, disclosing the tool for use as a pencil I erence holder with attaching means for the latter, Fig. 2 is a vertical section, Fig. 8 is a similar section, disclosing the cutting members in operative engagement with a pencil being sharpened, Fig. 4c is a section on the line 4cl of Fig. 3, Fig. 5 is a detail view of one of the cutter carrying members removed, Fig. 6 is a transverse section of the same, and Fig. 7 is an elevation partly in section of a slightly modified form.

WVith more particular reference to the drawings and bearing in mind that like refcharacters denote corresponding parts throughout the several views, a main or body part is provided comprising a front A, back B, sides C, and top D all of which parts are connected, conveniently an integral construction, and fashioned to form a relatively thin or fiat rectangular frame. The. said rectangular frame is preferably open at its lower end E and the top plate D has an opening d conveniently centrally thereof and preferably round for the loose reception of a pencil of the ordinary size and shape. Members E with a flat rear surface 6 and longitudinally curved inner surface 0, are pivoted one upon each side of the rectangular frame by means of pins F, adapted to pass through cooperating apertures in the front and rear surfaces A and B of the rectangular frame and said members E. These members E constitute the carrying members for the cutting tools proper. The pins F offer no obstruction beyond the surface of the frame and are adapted to be disengaged as desired to release the members E for any purpose. The said members E extend substantially throughout the length of the rectangular frame and normally occupy a position to the rear of the wall surrounding the opening d in the top D, the upper surfaces of the members E being curved at e to facilitate their swinging movement about the pivotal connection formed by the pins F.

The cutting members proper comprise substantially fiat blades G with relatively thin cutting edges g, and are secured in position conveniently by fitting the body portion thereof in slots g in the respective carrying members or holders E. These slots are arranged vertically at an inclination, there being two in each member E, and the cutting blades of the respective members when positioned incline from a point adjacent the outer edges of the members E at their upper ends, toward one another downward, whereby is provided in each member E a tapering recess between the two blades thereof. As previously described, the members E normally occupy a position to one side of the opening (Z in the head of the body support, and will offer no obstruction to the free insertion or positioning of a pencil to be sharpened. Means are provided for adjusting the members E and in turn the two pairs of cutting blades about the pivotal connection F, the said means conveniently comprising rods H threaded into apertures in the rear surfaces of the members E adjacent the lower ends of the latter, and the said rods H passing through longitudinal slots in in the sides C of the body part. Upon the outer ends of the rods H are knobs or engaging members I, constituting means whereby the members E may be swung about their pivotal connection F. The rods I are preferably curved, as shown in the drawings, and in view of this construction and the construction of slots it, it will be observed that when not in use the members E may be swung about their pivots and in this position the engag ing members I will occupy a position flat against the surfaces of the sides C of the rectangular frame or body part. A cushioning member K taking the form of a washer is mounted upon the top plate D of the rectangular frame and the opening thereof is slightly smaller than the opening (Z of said top D. A common means is provided for securing said cushioning means and retaining pins F in position, said means comprising a cap member L adapted to fit snugly over the upper end of the rectangular frame or body part and extending downwardly to a point beyond the connection of the pins F. Vhile it is preferred to have the cap member L detachable and only held in position by a frictional engagement, still if desired, the same may be secured in position by any suitable means. The cap member L has an opening Z therein in registration with the opening k of the cushioning member and the opening (Z of the top plate and is of a size slightly larger than the opening 70 of the cushioning member.

The operation of the tool may be briefly described as follows: The pencil or article to be pointed or sharpened is inserted through the respective openings in the cap plate L, cushioning member K, and top plate D into the rectangular frame the desired distance corresponding to the desired length of the point to be provided, which insertion is not hindered by any obstructions within the rectangular frame. When the pencil is properly positioned pressure is applied to the engaging members I conveniently by the thumb and forefinger of one hand when the cutting edges 9 of the blades G will be brought into contact with that portion of the pencil to be sharpened. By rotating the pencil back and forth, while maintaining pressure on the engaging devices, the pencil will be readily sharpened or pointed. By reason of the inclined position of theblades G, the proper taper to the pencil is obtained. These blades Gr may be detachably mounted in the slots 9 or permanently secured, it being preferable, however, to have the blades detachable, in order that the same may be renewed, if necessary. WVhen the tool is not in use, as previously stated, the engaging devices of the members E may occupy substantially flat positions against the sides of the rectangular frame and the device as a whole may be carried in the pocket, without any danger of cutting or tearing.

By reason of the fact that the opening in the cushioning member K is smaller than the openings of the cap member L and top plate D, the pencil will not be scratched or scarred by direct engagement with the wall surrounding the openings in the cap member and top plate. Again, the peculiar construction and arrangement of the cushioning member makes it possible to utilize the tool when not in use as a sharpener, as a pencil carrier, as illustratedin Fig. l of the drawings, and to this end suitable fastening means M may be provided for attaching the tool to the garment.

It may be desirable at times to insert the cap L and cushioning member K upon the bottom of the tool body and such a structure is illustrated in Fig. 7, it being noted that the pivots F for the cutter carriers in this structure may take the form of rivets or screws as shown to prevent their accidental separation.
