PENHOLDER.

SPECIFICATION forming part of Letters Patent No. 782,074, dated February 7, 1905. Application filed June 6, 1904. Serial No. 211,355.

To (U/ whom it may concern.-

Be it known that I, THOMAS MARsHALL SMITH, a citizen of the United States, residing at No. 2941 St. Paul street, Baltimore, Maryland, have invented certain new and useful Improvements in Penholders, of which the following is a specification.

Hy invention is an improvement upon pens of that class in which the pen-holding ferrule is movable upon the stern of the holder or handle for the purpose of ejecting the pen when it is worn out.

My object is to produce an effective ejecting device with the least possible change in the ordinary penholder; and my invention consists in a specific construction and arrangement of parts at once simple and effective.

It is illustrated in the accompanying drawings, in which- Figure 1 represents the handle and its stem in side elevation with the ferrule in longitudinal section and the pen in place, also in section. Fig. 2 shows a like section without the the pen. Fig. 3 is a like section of the ferrule in the act of ejecting the pen.

In the drawings is shown an ordinary penhandle having a reduced stem for the furrule. I have shown this stem as made of a metal sleeve .7), held upon the reduced part of the handle by means of a headed pin c. This stem is rigid and a plain cylinder. Over it is fitted the pen-holding ferrule C on its e Xterior of the ordinary cylindrical form and adapted to removably lit the stem, and for the necessary friction-contact a groove f is made in the rear inner surface of the ferrule to fit snugly over the head of pin a and hold by frictional contact, so that the ferrule will remain upon the stem in the use of the pen, but may be wholly removed in the act of ejecting the pen. For this forcible removal I adopt the interior shoulder on the ferrule, but make it to extend around the interior circumference of the ferrule, so that the pen at whatever point placed will be encountered by the shoulder in direct lineal movement. This shoulder is shown at (Z, and in front of it the ferrulecavity is enlarged to give space and frictional contact for the pen between the ferrule and stem. I have found this contact suflicient 5 with a solid or inelastic stem when the ferrule is permitted to have full movement and full throw in the ejection of the pen, and I do not claim this shoulder when it is on one side only of the stem and the pen is released by turning laterally, nor when the ferrule is limited in its longitudinal movement on the stem. By my construction it is provided that substan tially the only change made over the ordidinary cylindrical construction of stem and 6 sleeve is this, that the ferrule is held on the stem frictionallyand the interior of the sleeve is shouldered circumferentially, so as to strike the pen wherever placed when the sleeve is pushed from the stem. 5

I claim A penholder consisting of a handle, a plain rigid cylindrical stem thereon and a ferrule having an interiorly-enlarged annular end, an annular shoulder, said ferrule being ar- 7 ranged to be held on the stem by frictional contact, and to be wholly removed therefrom,

and to hold the pen by frictional contact, and

to eject the pen at any point of bearing on the end thereof, substantially as set forth.

In testimony whereof I aflix my signature in presence of two witnesses.

THOMAS MARSHALL SMITH.
