EJECTING-PENI-IOLDER.

Specification of Letters Patent.

Patented Feb. 6, 1912.

Application filed December 6, 1907. Serial No. 405,377.

To all whom tt may concern:

Be it known that I, SAMUEL KELLOGG WILL- soN, a citizen of the United States, residing at Dwight, in the county of Hampshire and State of Massachusetts, have invented certain new and useful Improvements in Ejecting-Penholders, of which the following is a specification.

This invention relates to the class of pen holders, and more particularly to those with means for eject-ing the pen points when it is desired to insert a new one, and has for its object to provide a simple device of this character whereby the pen nib may be ejected in an effective manner and without soiling the fingers.

Other objects and advantages will be apparent from the following description and it will be understood that changes in t-he specific structure shown and described may be made within the scope `of the claim with out departing from the spirit of the invention.

In the drawings forming a portion of this specification, and in which like numerals of reference indicate similar parts in the several views, Figure 1 is a side elevational View of the pen holder, Fig. 2 is a vertical longitudinal sectional View through the same, Fig. 3 is a cross sectional view on the line 3-3 of Fig. 2, Fig. 4 is a cross sectional view on the line 44 of Fig. 2.

Referring now more particularly to the drawings, there is shown a pen holder comprising the tubular stock 11. The outer end 10 of the stock has formed, therein, a face which gradually enlarges toward the outer extremity 14 and receives the pen nib- A and an outer enlarged end 14. Arranged in the tapered end of the stock there is shown a pen ejecting plug 15 comprising the

resilient jaws

16 and 17 respectively. These jaws are arranged to conform to the tapered end of the stock, as shown. A plunger 18 is arranged to work in the hollow portion of the stock at the butt end thereof, and this plunger is thus arranged to receive one end of a slidable coil spring 19 which is arranged between the plunger and the

jaws

16 and 17 respectively. The outer'end of the spring is secured to the plug 18 as by means of the eye 20. The spring at its inner end is also attached to the inner end of the

jaws

16 and 17 by means of a similar eye 21. The plug 18 is retained in the stock by any suitable means, as the pin 22 extending transversely through the plug and having its extremities disposed in the slots 23 formed in the upper and lower portions of the stock. It will thus be seen that a pen A may be insertedbetween one of the

jaws

16 and 17 and the wall of the stock 11, and by reason of the resiliency of these jaws the pen will be securely held to the stock. Vhen it is desired to eject the pen the plunger 18 is pushed forwardly in the stock thus contracting the spring 19, and in this movement of the plunger 18, when the tension of the spring 19 is greater than the frictional force holding the spring plug in position, the

jaws

16 and 17 will be pushed outwardly of the forward end of the stock 11, whereupon the pen point will be expelled. After a nib has been ejected, the plunger and the pen-holding elements are manually returned to their original position by the operator.

What is claimed is:

A penholder having a tubular stock, a coil spring slidably arranged within the stock, a spring jaw ejector plug within the end of the stock, and engaging therewith to clamp a pen nib, said ejector plug being cured at its inner end to one end of the spring, and an operating plunger slidably held within `the other end of the stock and secured to the other end of the spring, whereby when the plunger is pushed into the stock the spring will be compressed against the resistance of the ejector plug, and subsequently overcome said resistance and expand to force the plug from the stock sufficiently to release the nib.

In testimony whereof I aHiX my signature,

` in presence of two witnesses.
