PENHOLDER.

Specification of Letters Patent.

Application filed November 17, 1919. Serial No. 838,466.

T 0 ca w/iO-mir may concern:

Be it known that I, JAMES J. BOYLE, a citizen of the United States, and a resident of the borough and county of Bronx, in the city and State of New York, have invented a new and useful Penholder, of which the following is a specification.

The object of this invention is provide an ejecting pen-holder, which shall be eliicient for its particular purpose, and as a holder, which shall be economical for manufacture, and therefore meet an essential practical requirement, namely low selling price, and which shall be acceptable to purchasers as involving no departure from the form and feel of ordinary pen-holders. To this end the invention may be said to consist in the novel construction and combinations herein described and illustrated in the preferred embodiment, and more particularly pointed out in the claim. 7

In the accompanying drawings forming a part hereof:

Figure 1 is a perspective view of a penholder embodying the invention, in the act of ejecting a pen;

Fig. 2 is an enlarged longitudinal section through the forward part of the penholder, in the condition of Fig. 1;

Fig. 8 is a longitudinal section, with parts broken away and in elevation, showing the normal condition, with a pen in place;

Fig. 4 is an elevation of the forward part of the shaft of the penholder with a stem and filler integral therewith;

Fig. 5 is a front end elevation Without the pen;

Fig. 6 is a cross-section on the line 66 of Fig. 3;

Fig. 7 is a cross-section on the line 77 of Fig. 3; and

Fig. 8 is a side elevation of the metallic grip tube.

Figs. 1 to 7 will first be described.

The shaft 1 of the penholder, of wood or other suitable material, though preferably of wood, is provided at the front with a reduced cylindrical portion 2 forming the stem of a filler 3, between which and the grip member the pen is inserted. The filler proper 3, in this construction, is of wood, or of the same material as the body of the penholder, with which it is integral, and is made a little larger than the stem 2, though not as large as the forward portion of the shaft so as to provide a stop shoulderfi. in the sides of the filler are longi tudinal grooves 5, extending all the Way to the front, where their ends are open.

The grip part of the penholder preferably comprises a metal tube or sleeve 6 and a conventionally shaped grip 7 of rubber or other material held on the tube by outturned flanges 8 at the ends. The tube is of somewhat larger internal diameter than the filler 3, so as to afford a narrow space in which the pen can be placed and frictionally held. V-projections or indentations 9 are struck in from the tube intermediate its ends, in positions to enter and slide in the grooves 5. These projections constitute a simple and advantageous embodiment of positive ejecting means operated by the forwardly movable grip member. The grooves and projections are sufiicient in number, that is to say sufiiciently closely spaced in the circumferential direction, to insure that one of the projections will be behind the pen in any position which it may occupy. Four projections are shown, though I do not necessarily limit myself to this precise number.

Toward the rear of the tube in advance of the rear flange 8, a circumferential rib 10 is pressed in to constitute a stop element cooperative with the other stop element formed by the shoulder 4:. The relative positions ofthe stop and ejector are such that when the grip member is at its limit of forward movement the ejector projections 9 are at the front end of the filler, or substantially so.

The rib 10 bearing upon the stem 2, and the projections 9 bearing in the grooves 5, prevent any undue looseness, and the fit if desired may be frictional, though the operation is easier if the grip member slides freely on the stem and filler in the absence of the pen. The clearance between the grip tube and filler is such that the pen requires to be pushed in forcibly, and when in place holds the grip tightly against undesired movement.

To remove the pen, the shaft of the penholder is held in one hand and the grip grasped in the other and pushed forward against the frictional resistance. In so doing, the ejector projections 9 are carried forward in the grooves 5, and one or more of them positively advances the pen until it finally falls or is shot out as shown in Patented Mar. 15, 1921.

Fig. 1. There is no possibility of the projecfiller and stem being integral and the filler tions failing to catch the nib, or of the nib having a plurality of longitudinal grooves, lying passively or becoming wedged between a grip-tube slidable on the filler and stem, the relatively moving parts, The grip is With a circumferential nib-socket between 15 5 then slipped back to normal position, and a itand the filler, said tube being formed with fresh pen put in, whereby the grip is held a stop to bear on the neck and cooperate with firmly as just explained. said stop shoulder, and with a plurality of What I claim as new is: pressedin ejector projections disposed A pen-holder having a shaft and a. filler, around the circuit to operate in said grooves 2 10 with reduced stem between the filler and and eject the nib in any position.
