PENCIL HOLDER FOR CLIPBOARDS Filed June 29, 1962 INVENTOR F 615762 15. Zf/VSE/YMHFA'F United States Patent 3,127,649 PENCIL I-IIDLDER FOR CLIPBGARDS Russel R. Linsenrnayer, 2635 Grovenburg Road, Lansing, Mich. Fiied Jane 29, 1962, Ser. No. 206,410 1 Claim. (Cl. 2466) My invention relates to clipboards for holding papers, and more particularly relates to clipboards having a builton pencil holder.
It is an object of my invention to provide a new and improved clipboard having a built-on pencil holder.
Another object is to provide a new and improved clipboard of the character indicated, which is adapted to hold one or more pencils.
Still another object is to provide a new and improved clipboard of the character indicated, which can be easily manufactured at low cost.
All of the foregoing, and still further objects and advantages of my invention, will now be explained with reference both to this specification, and to the drawings, wherein:
FIGURE 1 is a plan view of my invention;
FIGURE 2 is an end view thereof;
FIGURE 3 is a fragmentary view of my invention, showing a pencil in secured position;
FIGURE 4 is a fragmentary view of a modified pencil clip; and
FIGURE 5 is a cross-section taken along the line 55 in FIGURE 4.
Referring now to FIGURES 13, there is shown a clipboard having a paper supporting board '10 and a paper holding clamp having a spring loaded movable member 12 attached to a fixed member 14, which in turn is secured to board Two spring steel clips 16 and 18, are riveted, welded, or otherwise secured to member 12 in spaced apart positions, aligned together horizontally. These clips can hold a pencil :20 which can be removed therefrom and replaced therein as necessary. Additional pairs of clips can be positioned above or below clips 16 and 18, to secure additional pencils, if desired.
In FIGURE 4, clip 18 is replaced by another type of 3,127,649 Patented Apr. 7, 1964 clip 22, comprising a base 32, carrying two adjacent curved spring-like elements 24 having a bent in and cut away section which has a circular hole 26. The periphery of this hole has a cutting edge. As a result, clip 22 can not only support one end of a pencil, but also can function as a pencil sharpener by placing the lead carrying end of the pencil in clip 22, and turning the pencil to sharpen same.
As shown in FIGURE 5, clip 22 can be surrounded by a hollow removable case 28, open at a pencil receiving end, and carrying a rubber element 30 to protect the pencil point. Case 28 serves to collect the graphite and wood dust during the sharpening operation, and can be removed and emptied as necessary.
While I have described my invention as applied to the drawings, my protection is to be limited only by the terms of the claim which follows.
In a clipboard comprising a board and a paper holding clamp secured to one end of said board, a pair of clips in spaced apart alinement to receive and hold a pencil, each of said clips having a base connected to said clamp and a pair of spring elements extending therefrom to engage the pencil to be held, the spring elements of one of said clips being bent inwardly toward one another and having cutting edges cooperating to form a circular opening therebetween through which the point of a pencil to be held is inserted and to additionally provide pencil sharpening means for such point of the pencil to be held.
