PENHOLDER.

menses.

To all whom it may concern.-

Be it known that I, MARCUS J. MITCHELL, a citizen of the United States, residing at Youngstown, in the county of Mahoning and State of Ohio, have invented certain new and useful Improvements in Penholders, of which the following is a specification, refer- "ence being had to the accompanying drawlngs. I

My invention relates to penholders and particularly to pen holders so constructed that the pen point may be readily removed therefrom.

The primary object of my inventionis the provision of a simple, cheap and easily operated pen holder so formed that retractlon of a certain portion of the pen holder will release the pen and permit it to be readily removed.

A further object of the invention is to provide in connection with the-pen holder above described a resilient means for forcing the pen point from its engagement with the holder when said member is retracted.

My invention is illustrated in the accompanying drawings wherein- Figure 1 is a view of the pen holder showing the sleeve retracted to permit the disengagement of the pen point; Fig. 2 is a longitudinal sectional view of the forward Fig. 3 is an end view thereof; Fig. 4: is a detail view of the cap or ferrule.

Referring to these drawings it will be seen that my improved pen holder consists of the wooden shank 2 whose forward end is re duced in diameter as at 3. Mounted upon this forward end is a cap or ferrule 4: of metal, this cap being split so as to provide two sections which may be forced toward each other to permit the insertion of the pen point and which will expand to hold the pen point in place.

Slidably mounted upon the body or shank 2 and surrounding the reduced portion of the shank is asleeve 5 which may be made of hard rubber or other suitable material. This sleeve at its rear end has an internal diameter equal to the diameter of the shank 2 rearward of the reduced portion 3 and at its forward end the 'sleeve has an internal diameter equal to that of the reduced portion. Thus the sleeve may slide upon the shank. Surrounding the reduced portion of the sleeve and bearing at one end against the shoulder 6 formed upon the shank 2 and at Specification of Letters Patent.

Application filed April 26, 1915. Serial No. 24,056.

its other end bearing against the shoulder 7 formed by the thickened wall of the sleeve is a spring 8. This spring spring expanding in diameter from the end engaging with the shoulder 6 toward the end which engages againstthe shoulder 7. spring acts to urge the sleeve 5 outward or toward the pen point engaging end of the shoulder. As illustrated in Fig. 2 the spring 8 isdecreased in diameter toward its rear end so that the spring 8 does not have any engagement with the sleeve and does not act to prevent f the sleeve. At the same time the spring-is entirely housed and protected. In order to prevent the spring from forcing the sleeve too far outward upon the pen holder, I prois a helical.

This I the free rearward movement vide a stop designated 9 which is operatively with a head constituting a stop 9, this stop or head projecting laterally outward beyond the periphery of the cap or ferrule. It is obvious that the tongue carrying the head or stop 9 may be forced inward sufficiently to release the sleeve 5 and permit the sleeve to be withdrawn from the pen holder shank, but that normally it prevents the release 0 the sleeve from the pen holder shank.

In order to positively force the pen point out of engagement with the cap 4 when the sleeve 5 is retracted, I preferably provide a spring 10. While I do not wish to limit myself to the exact manner of supporting the spring, tegral with the cap 4. The spring is bowed intermediate of its ends and bears against the inner surface of the sleeve, and may be struck up from the cap, as shown.

With the construction above described it will be obvious that the spring 10 will assist in holding the pen point securely in place but it will be plain that upon a retraction of the sleeve against the force of the spring 8, the sleeve will release the shank of the pen point and the spring 10 will force the shank outward even though the pen point adheres to the cap or ferrule 4 by reason of the caking of ink thereon.

It will be plain that my pen holder has all great a forward movefee I preferably form the spring 1n- 7 the qualities of an ordinary pen holder but with the added advantage that the pen may be readily removed therefrom without having to pull the pen out and possibly break the pen at the points of its engagement with the pen holder, thus destroying the usefulness of the holder. Furthermore, it will be obvious that in order to remove the pen it is not necessary to touch it and thereby -.get ink upon the fingers. It is only necessary toretract the sleeve and even if the pen is not forced out or ejected by the action of the spring 10., it may be readily disengaged by bringing the pen in contact with a desk or some other body whereupon the pen will fall from the holder.

Having described my invention what I claim is: l i

1. A pen holder including a shank having a reduced end portion, a cap permanently mounted upon the extremity of said reduced portion, said cap being formed of metal split to provide yieldable pen engaging sections, and a resilient tongue, the extremity of the tongue being formed to provide a laterally projecting head, a sleeve slidably mounted upon and surrounding the shank and cap, a spring inclosed within the sleeve and surrounding the shank and urging the sleeve outward against the stop. I

2. A pen holder including a shank, a cap mounted upon the extremity of the shank,a longitudinally bowed pen engaging spring projecting beyond the surface of the cap, the end of the spring being disposed within a slit in the cap, a sleeve surrounding the shank and cap and longitudinally slidable thereon, and a spring surrounding the shank and disposed within the sleeve and urging said sleeve to a projected position.

3. A pen holder, a shank having a reduced portion, a cap mounted uponthe extremity of the reduced portion, said cap being split to provide a longitudinally extending tongue having a laterally extend,

ing head forming a stop and also being split to form a longitudinally extending outwardly bowed resilient tongue, a sleeve surrounding the body of the shank and the reduced portion thereof and said cap and longitudinally slidable upon the shank, the

bore of said sleeve end and a helical reduced portion of being enlarged at its rear spring surrounding the the shank and bearing against the sleeve and inclosed thereby and urging the sleeve into a position against said stop, and a resilient pen ejecting memberg carried upon said cap.
