PENHOLDER.

SPECIFICATION forming part of Letters Patent No. 647,679, dated April 1'7, 1900. Application filed December 18, 178799. Serial No. 740,753. (No model.)

ATo all w/wm, t may concern.-

Beit known that I, EDWIN METCALF, a citizen of the United States, residing at Norristown, in the county of Montgomery and State of Pennsylvania, have invented a new and useful Improvement in Penholders, of which the following is a specication. Y

My invention relates to the class of penholders that can b e operated to eject or loosen a pen that has become so tightly lodged in the holder that it cannot be removed by pulling it outwith the fingers or even witha pair of pliers, pens becoming frequently so tightly lodged that they will break off outside of the holder before the portion within the holder engaged by the threads a. 'lhe forked part consists, preferably, of two projections Z2 b, formed by the two longitudinal slots or slits b b. They are beveled at their free ends, as shown in the views. These slots may be made so narrow as to constitute slits only, and there may be three or more of the slots or slits, without departing from the scope of my invention or otherwise altering the oonstruction or operation of my device.

Ashort tubular or sleeve member C is made preferably tapering internally and has the larger end of bits bore uniform and screwthreaded, as shown in Fig. 4. To facilitate rotating this sleeve, vit may be milled at one will release itself.

The object of my invention is to overcome these difficulties by so constructing and arranging the several members of the holder that the two portions of the holder in contact with the pen can be given a movement of ro-.

tation and also a telescoping movement with respect to each other.

Referring to the accompanying drawings, in which the letters of reference indicate the same parts throughout the several views, Figure l shows the penholder in perspective. Fig. 2 shows it in section, the handle being in plan. Fig. 3 shows in enlarged plan the several members of the holder in the sequence in which they are assembled. Figs. 4, 5, and 6 show in enlarged section the members shown in Fig. 3 and in the same order. Fig. 7 is an enlarged section on the line 7 7 of Fig. 2.

In the several figures, D is the stem portion of the holder, which may be made of wood or othersuitable material. A barrel or tube A is secured to the stem D either by or more places, and 1t 1s preferably reduced at the smaller end and curved off at the eX- tremity, as shown in the views.

After the part B has been secured to the member A with a few of the threads b" not .engaged by the sleeve the sleeve C is slid on vover the projections b Z7 and its threads c engage the exposed threads b, and it is screwed up till it assumes the position shown in Fig. 2, when the holder is ready for use.

When the pen is inserted, it is securely held in place between the sleeve C and one of the spring projections h, as will be apparent from inspection of Figs. 2 and 7.

Should it be desired to remove the pen, the sleeve C is given several rotations, and then the threads being disengaged it is slid oif, when the pen will usually fallout; but if the pen is in strong adhesion with the part b after the sleeve C has been removed the pen can then be readily detached, as will be obvious.

While it is preferable to have the parts connectin g by means of screwthreads,other mode of connection may be used, such as a bayonet-joint or even a tapering telescopic joint.

' The three members A, B, and C being disconnectably attachedl are very easily kept clean and free from accumulation of ink and rust. or even the members A, B, and D, may be permanently connected or may be made integral, the essential features of my invention comprising the slit or forked portion of the member B and the sleeve C sliding on over Yet, if desired, the members A and B,

as set forth.

2. The combination in a penholder, with 'the handle and the barrel attachedthereto having an internal screw-thread at its lower end, of a spring member having an enlarged screw-threaded portion at one extremity and longitudinal projections at its other extremity, said enlarged threaded portion being partly engaged by the threads of said barrel, and

another tubular member having internal screw-threads at one end also engaging said enlarged` threaded portion and inclosing said projections, substantially as set forth.

In testimony whereof I have signed my 'name to this specification in thev presence of two subscribing witnesses,

EDWIN METCALF. Witnesses:
