HOLDER FOR GRAPHIC INSTRUMENTS.

Application iii-ed February 16, 1925. Serial n... 9,450.

ments, of which the following is a complete specification.

This invention relates to a holder for graphic instruments such as a pen, pencil,

' brush or stylus where it is desired to secure a uniform weight on the operating point and a consequently uniform line regardless of whethera down, up or lateral stroke 1 is being made.

Another object is toproduce a holder of the general character outlined having means whereby the holder can be adjusted to accommodate the angle at which various writers may habitually hold the graphic instrument.

A further object is to provide a holder of the general character mentioned which may be readily provided with additional weight to press harder on the working point.

A still further object is to produce a graphic instrument holder of the character outlined which is of strong, simple, durable and inexpenisve construction; and in order that it may be fully understood, reference is to be had to the accompanying drawing, in which a v Figure 1 is a central vertical section taken through aholder embodying the invention, it being noted that it is illustrated in connection with a writin pen, the body of the pen being somewhat s orter than would be the case in actual practice. Figure 2 is a section similar to that of Figure 1 but at ri ht angles thereto.

Figure 3 is a si e elevation of the pen as it will appear when not in use.

Figure 4 is a section on the line IVIV of Figure 1.

In the said drawing, where like reference characters identify corresponding parts in all of the figures, 1 indicates the barrel of a fountain pen equipped with the customary nib 2 and internal ink sack 2, said barrel being of any common or ordinary type and of c lindrical form. Molded integrally with the arrel, on opposite sides thereof and extending laterally therefrom, are a pair of ribs 3.

. The pen 1 is received within a holder 4 having a bore of sufiicient diameter to slidinafter appear.

ingl receive the en, and adjacent the point of t e pen, said older has an enlarged internal recess 6 for a purpose which will here- Communicating with said recess are the ends of a pair of oppositely disposed internal slots 7 for the reception of the ribs 3 of the barrel of the pen, it being understood that the slots are of greater length than the ribs.

The internal face of the recess 6 is threaded for the reception of a threaded sleeve 8 having its bore of sufficient diameter to snugly receive the barrel of the pen without offering any appreciable resistance to the sliding thereof. The barrel of the pen is thus free for sliding back and forth within the holder, being limited in its rearward movement through contact of the rear ends of the ribs 3 with the rear ends of the slots 7, and in its forward movement through contact of the front ends of the ribs 3 with the collar 8, the interlocking ribs and slots also serving to prevent rotation of the pen barrel. By threading the sleeve 8 back and forth, the range of forward movement of the pen may be adjusted to fit varying conditions as will hereinafter appear.

Secured to the holder 4at a point in line with the pen nib is a fixed guide 9 bowed out to permit the pen cap 10 to be screwed on the end of the holder as common, and

said guide is equipped with a ball extremity at its lower end. When the device is in use the guide 9 will be in constant contact with the writin surface and transmits all of the pressure 0 the writers hand direct to such surface. The pressure on the writing point is thusthat of the weight of the pen barrel alone and a uniform line is thus secured, although, if desired, suitable weights may be inserted in the end of the holder as at 11 to press down on the pen barreland increase tihe pressure on the point to trace a heavier In the use of the device, the guide 9 is always maintained in contact with the writing surface, the pen point being elevated at the end. of a word and the like, by a slight movement in the direction indicated by the arrow a around the end of the guide. This I movement effects the upward sliding movement of the holder until the sleeve 8 abuts the ends of the ribs 3 and consequently degree of movement of the holder necessary to elevate the point may be adjusted by manipulation of the sleeve 8, this adjustment also being necessary to compensate for the different angles at which various users may hold the pen.

In actual use, the pen barrel will possess but a slight range of sliding movement, as the angle of the pen in writing is seldom shifted to any great extent. The proportion of the parts will be such that the end of the barrel of the pen will be just about parallel with the end of the holder when the pen is at its limit of inward or inoperative position.

As it may be desirable at times for the operator to press with a greater force of the nib of the pen than-that ofthe weight of the barrel sleeve, a friction plug 12 (see Figure 1), is mounted in the holder 4 and slightly projects therefrom. The inner end of said plug terminates in an enlarged face 13 for engagement with the barrell of the pen. With this construction it will be apparent that the operator can arrest the sliding movement of the pen when he desires to cross\a letter T or the like, by imposing pressure on the projecting end of the plug.

From the above description it will be apparent that I have produced a holder of the character outlined which possesseslall 0f the features of advantage set forth as desirable,

and while I have described and claimed the the right to make all changes properly falla ing within the spirit and scope of the appended claims.

I claim:

1. A holder, a guide on said holder, a graphic instrument freely sliding in said holder, means for preventing the rotation and limiting the sliding movement of said instrument in one direction, and adjustable means for limiting the sliding movement of the instrument in the other direction.

2. A holder havin an internal slot, a

graphic instrument reely sliding in said holder and having a rib engaging the slotof the holder, an external guide secured to said holder, and an adjustable sleeve adapted to be adjusted to limit the sliding movement of the instrument in one direction within predetermined limits. 3. A holder having an internal slot, and an internal recess at one end, a graphic instrument freely sliding in said holder and having a rib engaging the slot of the holder, and an adjustable sleeve in said holder recess adapted to limit the sliding movement of said instrument in one direction.

4. A holder, a guide on said holder, a graphic instrument freely sliding in said holder, means for preventing the rotation and limiting the sliding movement of said instrument in one direction, adjustable means for limiting the sliding movement of the instrument in the other direction, and friction means for preventing the sliding movement of said instrument.

5. A holder having an internal longitudinal slot and at one end an enlarged threaded recess, a graphic instrument freely sliding in said holder and having a rib engaged with the slot thereof, a sleeve threaded in the end recess of said holder, and a manually'operable friction device carried bv the holder and adapted to 1 apply friction against said graphic instrument.

In witness whereof I hereunto afiix my signature.

. ERNEST SHAW.
