DRAFTSMAN'S PENCIL HOLDER AND THE LIKE Filed NOV. 12, 1965 INVENTOR 3,273,846 DRAFTSMANS PENCHL HOLDER AND THE LIKE Baltzar Leo De Mar, 627 W. Belair Ave., Aberdeen, Md. Filed Nov. 12, 1965, Ser. No. 507,594 10 Claims. (Cl. 248-226) This invention relates to a draftsmans pencil holder and more particularly to a holder for pencils, pens or other implements having sharp points, and is adapted to be secured on a drafting board, table or like support.

Draf'tslmen, engineers and like professionals, use penciles of many grades of hardness, also pens. It has been the usual practice to lay them on the drawing board, or place them in a can or glass container that is placed on the board. Since most draftsmens boards are slanted, these pencils or pens were inclined to roll down and interfere with their work. If a can or glass were used, they [would also slide down the board.

When the pencils or pens were the points were damaged.

The present invention obviates the aforesaid ditficulties by providing a tube adjustably attached to a bracket which, in turn, is secured on the edge of the drafting board. The tube contains a plug of resilient material placed at the bottom thereof to protect the points of the pencils or pens. The tube is adjustable at any angle for the convenience of the user.

It is an object of this invention to provide a pencil and pen holder for draftsmen that eliminates the necessity of placing them on the drawing board of a draftsman.

Another object is to provide a pencil holder that is attached to the edge of a drawing board and is further, adjustable at any angle for the convenience of the user.

A further object is to provide means in the pencil holder to protect the points of the pencils when stored therein.

A still further object is to provide a pencil holder in which the point protector is easily replaced by a new one A final object is to provide a pencil holder that is simple of construction and economical of manufacture.

These and other objects and advantages of the present invention will be fully apparent from the following description when taken in connection wvith the annexed drawing, in which:

FIG. 1 is a perspective view of the pencil holder of the invention as in use;

FIG. 2 is a vertical sectional view taken along line 2--2 of FIG. 1;

FIG. 3 is a top View of a modified means of securing the pencil holder to adrawing board;

FIG. 4 is a similar view of a further modification;

FIG. 5 is an end view of a modified form of bracket for use with the pencil holder;

FIG. 6 is a similar view of a further modification; and,

FIG. 7 is a still further modification.

Referring in detail to the drawing in which like reference numerals denote like parts throughout the several views reference numeral 1 designates, generally, the pencil holder of this invention.

Pencil holder 1 comprises a tube 2 which may be of glass or other transparent material for observing pencils of short length. As seen in FIG. 1 tube 2 is supported in a block 3 which may be of brass or like material, which is centrally bored as at 4 and in which bore tube 2 is frictionally held. To prevent accidental axial movement of the tube 2 in bore 4, a set screw 5 (see FIG. 2) is driven into one side of block 3 and bears against tube 2.

Tube 2 is closed at its bottom by a cap 6 which may be held frictionally or by threads (not shown) thereon.

Block 3 is further provided with a threaded bore 8 in the side opposite set screw 5 and a pin 9 passes through block 3 and pierces stud 7 to prevent its rotation in bore 4.

placed in a can or glass,

United States Patent 0 Patented Sept. 20, 1966 A means for mounting pencil holder 1 on a drawing board (indicated by 10 and illustrated by broken lines) is provided and, as shown in FIG. 1, consists of a bracket 11 which is bored at its upper end as at 12.

Bracket 11 is provided with a pair of holes 13 at its lower end. Screws 14 (shown by broken lines in FIG. 1) fasten bracket 11 to board 10 through holes 13 as shown.

A wing nut 15 threaded on stud 7 permits ready adjustment of tube 2 at any angle desired.

A means for protecting a pencil point is provided and consists of a plug of resilient material 16 set in the bottom of tube 2 as shown, and can quickly be replaced by removing cap 6 and inserting a new one therein.

A pencil indicated by 17 (shown in broken lines) is illustrate-d to show how it is placed in the tube 2 and the point protected by plug 16.

Pencil holder 1 may be used to hold drafting instrurnents that have sharp points as well as pencils and pens.

Other means for mounting the tube 2 on a drafting board can be used and two such modifications are shown in FIGS. 3 to 7.

In FIG. 3 a split ring 18 is substituted for block 3 and encircles tube 2. A nut 19 and bolt 20 holds the ends of split ring 18 together and by tightening bolt 19 split ring 18 is constricted around tube 2 to hold it firmly therein.

One end of split ring 18 is elongated as at 21 and is turned downwardly as at 22 and inwardly as at 23.

A thumb screw 24 is passed through leg 21 and threadably engages a square nut 25 which is held against rotation by turned in portion 23. The operation is the same as the holder in FIG. 1.

The modified holding means seen in FIG. 4 is also a split ring, but the ends are equal and are joined by a nut 26 and bolt 27. The middle of split ring, opposite nut 26 and bolt 27 is turned outwardly, downwardly and inwardly as shown and forms a C-shaped portion 28 which holds square nut 25 against rotation.

A further modified bracket 29 is shown in FIG. 5 for detachable engagement with an edge of board 10 and consists of an angle piece 30 which has a threaded hole 31 in its bottom leg 32 and receives a thumb screw 33 therethrough. A foot 34 carried by the upper end of thumb screw 33 bears against the underside of boa-rd 10 and a toe plate 35 spaced from leg 32 and fixed to bracket 30 rests on the top of board 10.

The bracket is secured by turning thumb screw 33 to bring toe plate fast on the top of board 10.

The modification shown in FIG. 6 is a simple angle piece, and as shown, consists of a single angle piece 36 which is screwed to the top of board 10 by a screw 37a through a hole 37 in the lower leg 39 of angle piece 36.

The modified holding means shown in FIG. 7 is for quick attachment to board 10 and is essentially the same as that shown in FIG. 5 with the exception of the thumb screw 33 which is replaced by a spring loaded clamp indicated generally by 38.

The user merely grasps the levers 39 and 40 and squeezes them together which moves lever extension 41 which bears against the underside of board 10 and removes the bracket for placement at another point on board 10.

Lever 39 is pivoted to the lower end of bracket 42 as at 43 and levers 39 and 40 are biased apart by spring 44. A toe plate 45 is fixed to bracket 42 as in FIG. 5.

While only preferred forms of the invention are shown and described, other forms are contemplated and numerous changes and modifications may be made therein without departing from the spirit of the invention as set forth in the appended claims.
