NIB-EJECTING PENHOLDER.

SPECIFICATION forming part of Letters Patent No. 661,910, dated November 1.3, 1900.

Application filed September 27,1900. Serial No. 31,294. (Noimodel.) l I To all whom t may concern:

3e it, known that I, FREDERIC LIONEL GRAHAM, a subject of the Queen of Great Britain and Ireland, residing at Nareen, in the Colony of Victoria, Australia, have invented certain new and useful Improvements in NibEjecting Penholders; and Ido hereby declare the following to be a'full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The object of this invention is to provide improvements in penholders of that class wherein the nib is ejected by the operation of a part permanently attached to the penholder.

In carrying out my invention I avoid faults which would militare against its extensive adoption. I avoid making it heavy, costly, clumsy, or liable to get ont of order. The upper end of the penholder is capable of use as a paper-knife.

To these ends, first, I make'each member of my penholder of simple and durable construction second, the casing of the penholder is not necessarily larger than in ordinary penholders and is of wood, vulcanite, or other material; third, the number of distinct parts in my penholder is four, and, fourth, the assemblingof these four parts can be performed rapidly without special tools or skilled labor.

I illustrate my invention by which the above advantages are secured in the accompanying drawings, in Which- Figure l shows my penholder in longitudinal section in the position assumed when the spiral spring, hereinafter referred to, has been strongly compressed and has ejected the nib. In the normal position of the parts in Fig. 2 the said spring is compressed slightly. Fig. 2 shows in longitudinal section the parts assembled'in normal position with nib inserted; Fig. 3, the plunger with its spiral spring;

Fig. 4L, a perspective view of a part to be permanently fixed within the casing; Fig. 5, a longitudinal section of the casing, and Fig. 6 a cross-section on the line w to y in Fig. 1. The plunger upper end in Fig. 1 is modified in Figs. 2 and 3.' Fig. l exhibits the preferred casing, which keeps the plunger from turning, prevents it being pushed objectionably far when ejecting the nib, and enables lower end (in dotted lines in Fig, 3) is curled up, as shown by firm lines, and slitted in any usual manner to form a nib-h0lding part e in size such as when slightly compressed to fit in lower end of casing a and when further compressed to allow of a nib being insei-ted and held tight in the casing, as seen in Fig. 2. Then (in order) there is on the plunger a rib f, against which the back end of the nib is to abut, then a narrow spindle g, then a cylindrical or tapering curled-up portion h, adapted to fit closely against the inner walls of the upper end of the casing, and then a flat (preferably) metal endl of the plunger, this end being normally exterior to the casing and preferably tapering.

k is a spiral spring slipped loosely over the spindle g. The upper end of the spring 7o abuts on the inner extremity of the upper curled portion h of the plunger, and the lower end of the spring k abu ts against the arc or Split ring t', which is slipped over the plunger into such position that the inner extremity of the rib fshall abut against it. Each of the ends of this split ring acts as a stop. It may be called a double-abutment ring, as the edges at each end are turned in as marked j, and it is springy-that is, can be compressed or expanded, resuming when free its normal diameter.l The plunger, with spring la extending the full length of spindle g, will pass easily into place in the' casing a, but the ring t' has to be compressed, so that it may do so. Ring 2 and spring k being put in place on the plunger the whole are pushed into casing a, the ring t' being sprung into the enlargement c from its compressed condition and litting the same tightly, the shoulders or edges j of the ring nevertheless projecting into the bore h, so' that the spring la and the rib f shall abut against the said edges IOO casing a wider, longer, and better paper-` outter or blade Z is in that oase provided than otherwise, and the shoulder m is stopped by the slit end when the part e is sufficiently protruded, such stoppage being an advantage.

The aboveeonstruetion is .that in which my: invention is best embodied; but minor details may be modied without departing from theA spirit of my improvements.

What I claim as my invention, and desire i to secure by Letters Patent of the United States, is-

1. In a nib-ejecting penholder, the combinationwiththe hollow easing having near the nib endan enlargement of its-bore, and having a double-abutment spring-ring sprung thereinto, and a Vslit in its other end, of a spring-retracted plunger having integrally, in the order'stated, the curled-up portion e, rib f, narrow spindle g, curled-up portion h, a shoulder fm and a paper-cutter end [,'all substantially as and for the vpurposes set forth.

2. In a nib-ejecting penholder the combination with the hollow easing having near the With a shoulder.

nib end an enlargement of its bore and having sprung thereinto a split ring i having at each end turned-in edgesj to serve as abutments, of a plunger having integrally in the order stated, the curled-up portion e, rib f, narrow spindle g, a spiral spring lo extending the full length of 'the spindle and bearing against an abutment of ring t', curled-up portion h, ,and the projecting paper-cutter or blade l all substantially as and for the purposes set forth.

3. In a nib-ejeeting penholder, the Combination with the hollow veasing having near the nib end an enlargement of its bore, and having sprung thereinto a split ring 'L' having at each end turned-in edges j to serve as abutments, of aplunger having integrally in the order stated the curled-up nib-holding portion e, the yrib f, narrow spindle g inelosed by a spiral spring, a curled-up portion `h fitting within the bore of the easing, and an extremity projecting from the end of the easing, all substantially as Aand for `the purposes set forth.

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

FREDERIC LIONEL GRAHAM.
