PEN-HOLDER.

SPECIFICATION forming part of Letters Patent No. 246,769, dated September 6, 1881.

Application filed June 22, 1881.

T all whom it may concern.-

Be it known that I, JosEPH GOODMAN Has- TER, a citizen of the United States, residing at Washington city, District ofOolumbia, have invented new and useful Improvements in Pen- Holders, of which the following is a specification.

Pen-holders as ordinarily constructed are provided with a pen-slot at one end, arranged between two immovable surfaces or cylinders, and the removal of the pen therefrom when necessary, by reason of the same becoming worn or broken, is rendered exceedingly diilicult when it has become cemented in place by corrosion. To avoid this difficulty it has been suggested to arrange within the barrel of the holder proper asliding plug, between which and the barrel the pen is held. This sliding plug has been arranged to operate automati- 2o cally to eject the pen by the force of a spring arranged at its upper end, and which is compressed when the plug is in its normal position, and so held by a short button or pin looking in a bayonet-slot in the barrel of the holdor; and it has also been arranged without a spring and operated positively by a pin or button projecting through a straight slot in the barrel of the holder. I have discovered that these methods only partially overcome 0 the difficulties, because where spring-pressure is used it is difficult to preserve the proper amount of power, the necessity for which increases as the pen becomes more firmly attached to the parts by long use, corrosion, &c., and because the continued confinement ot' the spring and the ordinary crystallization of the metal tend to rob it of its elastic force; and where the positive action is provided for in the sliding block with projecting pin or but- 0 ton the force is applied to such pin or button, which must of'necessity be small and arranged .at one side, and hence it is difficult of operation.

The object of my invention is to overcome all the disadvantages named and provide a pen-holder with an ejector which shall be positive in its action and unlikely to become broken or disarranged; and with these ends in view my invention consists of a pen-holder so bored or open centrally from end to end, and

(No model.)

provided with an axially arranged ejector longer than the pen-holder, and having one end adapted to confine a pen between itself and the inside of the barrel of the holder, the opposite end projecting beyond the upper end of the holder a sufficient distance to enable a longitudinal movement to be given to a suitable' degree to eject the pen, as will be hereinafter and in detail explained.

My invention further consists in the special details of construction of the several parts,-as hereinafter set forth and specifically claimed.

In order that those skilled may fully understand the construction and operation of my improved pen-holder, I will proceed to describe the same, referring by letters to the accompanying drawings, forming part of this specification, and in which Figure l is a central longitudinal section of a pen-holder embodying my invention. Fig. 2 is a similar view with a spring attached to return the ejector to its normal position after the ejectment of the pen; Fig. 3, a similar view of a modification of my invention, showing the spring arranged internally and the head of the ejector provided with radial projections to limit the return movement of the same. Fig.

4 is a cross-section taken at the line or .r of Fig. 1; Fig. 5, a partial longitudinal section with the pen held in position for use; Fig. (3, a simi- 8o lar view with the ejector forced out and the pen discharged, and Fig. 7 an end view of the radially-enlarged ejector-head in the modified form shown at Fig. 3.

Similar letters indicate like parts in the several figures.

A represents the handle of the pen-holder, which may be made of wood, hard rubber, or other suitable material, preferably tapering in form, though any other desired form may be adopted. Thisholderismadehollow,orformed with an axial bore from end to end, adapted to receive a lon gitudinall y-reciprocatin g ejector, B, which is provided at its forward end with a head, 0, the inner end of whichis pref- 5 erably made tapering, and adapted, when in its normal position, to rest against an annular shoulder, a, on the interior of the pen'holder. The relative diameters of the pen-holderAa-nd head G of the ejector are such that sufficient I00 space is left between the surfaces of the two to accommodate and securely hold the pen when placed in position.

The periphery of the head (J maybe notched or grooved longitudinally, as shown, to form a seat for narrow pens.

The ejcctorB maytitloosely within the holder A, as shown; or the rod and the axial bore of the holder may be of a near diameter, so that theejector may be operated and guided through an exact axial line.

The movement of the ejector, both to eject the pen and return the former to its place, may be positive and by hand, as shown at Fig. 1; or thepenniay be ejected positively by the application of power to the upper extended end of the ejector and the ejector returned by a spring, I). This springl) maybe secured in operative position between the upper end of the pen-holder and a nib, b, on the end of the ejector to form an ornamental finish, as shown at Fig. 2; or it may be secured nearer the center by being fastened at one end to the case and confined at the other by a collar, 0, secured to the ejector, which collar is slightly tapered and adapted to find its seat within the holder A by wedgin g.

The upper end of the ejector B may project, as seen at Fig. 1, or it may be concealed by and connected to a short telescopic cap, E, Fig. 3.

The shoulder a, which stops the ejector at the proper point, as seen at Figs. 1 and 2, may be used to control the depth of insertion of the pen, and the return movementof the head O of the ejector limited and determined by one or more short radial arms or flanges, d, (see Fig. 7,) so arranged or disposedastoleave one or more spaces, 0, for the reception of different sizes of pens.

TheejectorB maybe ot'one diameter from its head up, as shown at Figs. 1 and 2. It may be tapered, or it may be stepped and of differ ent diameters, corresponding to different diameters in the bore of the holder, as shown at Fig. 3.

The ejector-head C may be perfectly cylindrical throughout its entire length, as shown at Fig. 3; but I prefer to taper the inner end, as shown at Figs. 1, 2, and 6, so that when projected, as shown at Fig. 6, the pen will be free to fall out by its own grayity should the ejector fail to carry it, which is not likely.

In introducing the pen it attaches itself with greater frictional tenacity to the ejector-head 0 than to the barrel of the holder, and hence manner that an extra amount of power applied r will not injure or disarrange the parts; and the gist of my invention rests in this broad idea, the details of my invention resting in the several peculiarities in the arrangement of the spring and the particular form of the ejectorhead.

Having described my invention, what I claim as new, and desire to secure by Letters Patent, lS

1. In combination with a pen-holder open or bored centrally from end to end, a reciproeating ejector, B 0, adapted to confine the pen at one end and extended at the opposite end beyond the end of the holder, substantially as and for the purpose set forth.

2. In combination with the holder A, bored or open from end to end, and the ejector B 0, arranged therein, as described, and adapted to be operated positively, as set forth, to eject the pen, a spring, 1), adapted to return the ejector to its normal position.

3. In combination with the pen-holder A and.

ejector B O, the telescopic cap E, for concealing and protecting the upper end of the ejector, as hereinbefore set forth.

4. The ejector-head (l, adapted at its outer end to confine the pen in place against the barrel of the holder, and having its inner end tapered, as described, to insure the releasement of the pen, as hereinbefore set forth.

5. The head 0 of the ejector, having its outer end formed with one or more radial arms or projections, d, in combination with the end or annular shoulder of the holder A, whereby the return movement of the ejector is limited, substantially as hereinbet'ore set forth.

In testimony whereof I have hereunto set my hand and seal in the presence of two subscribing witnesses.

JOSEPH G. HESTER.
