. To all whom it may concern.

Be it known that I, JOSEPH F. DAY, a citizen of the United States, residing at Pittsburgh, in the county of Allegheny and State of Pennsylvania, have invented new and useful Improvements in Combined Fountain Pens and Pencils, of which the following is a specification.

This invention relates to writing instruments, and more particularly to a combined fountain pen and pencil.

One of the main objects of the invention is to provide a device of the character stated of simple construction and neat appearance having simple and eflicient means for carrying a pencil eraser. A further object is to provide simple and efficient means whereby a pencil member may be readily attached to a fountain pen thus providing a combined pen and pencil writing instrument. Another object isto provide a pencil member of simple and eificient construction having simple and eflicient means for feeding or projecting a stick ofgraphite as the same is worn away. Further objects will appear from the detailed description.

' In the drawings:

Figure 1 is a side view of an instrument constructed in tion.

Figure 2 is a central longitudinal sectional view of the instrument, the pen and pencil members being shown in elevation.

Figure 3 is a detail of one of the clamping jaws and associated parts.

Figure 4 is a detail of the clamping jaws and associated parts taken at right angles to Figure 3.

. A fountain pen 1 of any preferred or suitable type is provided at one end with a threaded collar 2 which receives stud 3 proaccordance with my invenvided at the inner end of a cylindrical mem-.

her or body 4. This member is provided with an axially disposed tubular member 5 forming a bore in the upper portion of which is mounted an expansion coil spring 6 the outer end of which bears against a disc 7 slidable in the bore. This disc presses against the inner end of a stick 8 of graphite which normally projects beyond the outer end of member 4 to provide a writing point. The outer end portion of member 4 receives a conical sleeve 9 provided at its inner end with an interiorly threaded collar 10 which threads onto a co-operating threaded collar 11 of member 4:. A pair of gripping or clamping jaws 12 ,are hinged to: the lower;

end of member 5 at opposite sides thereof, at'13. These jaws are adapted, when forced toward each other, to tightly grip the graphite stick 8 so as to secure the same against outward movement. By adjusting sleeve 9, the jaws 12 may be released or forced into clamping engagementwith stick 8, as desired, thus permitting ready adjustment of the writing-point. As will be understood,

simple and efficient means whereby the in-' strument may be readily converted into a pencil, the eraser 17 being readily available for use. In addition, by providing the memher 4 and associated parts, a fountain pen of standard construction may be readily converted into a combined pen and pencil.

What I claim is 1. In a writing instrument, a tubular member, a writing stick slidable in said member, gripping jaws hinged at their inner ends to the outer end of said member and freely movable toward and away from each other, means for forcing the jaws toward each other for gripping the stick, and means for forcing the stick outwardly of the tubular member.

2. In a writing instrument, a tubular member, a writing stick slidable in said member, two opposed gripping jaws hinged at their upper inner end to the outer end of said member and freely movable toward and away from each other, means for forcing the stick outwardly of the tubular member, and removable means for forcing said jaws toward each other. e v

3. In a writing instrument, a body, a tubular member mounted in the body, a writing stick slidable in said member, two op.- posed gripping jaws hinged at their upper inner end to the outer end of said member wardly of the tubular member, and an outwardlytapering sleeve threaded upon theof-thetubular-1nember, said jaws diverging body, tlio1itrend of'the sleeve-fitting about toward the tubiilarnieniber andcthe Writing the jaws and the jaws, when in operative postiok'passing between the jaws, and a sleeve sition, diverging. toward fthe-tubular 'mem threaded ontdthe body and having an outer 5 her. outwardly tapering portion fitting about the 15 4.
