Specification of Letters Patent.

Patented Nov. 12, 1907.

Application filed June 12. 1907- Serial No. 378,518.

To all whom it may concern:

' Be it known that I, FREDERICK R. WELLEs, a citizen of the United States of America, and a resident of the borough of, Brooklyn, city of New York, county of Kings, and State of New York, have invented certain new and useful Improvements in Pencil-Holders, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof.

My invention relates to improvements in pencil holders of the type adapted for holding and supporting short pieces of the ordinary Wooden pencils, so that such short pieces may be comfortably used practically to the end.

The objects of my invention are, first, to render the device as light in weight and as inexpensive to manufacture as, possible; second, to provide for the rigid clamping of the pencil, so that it will be held firmly and steadily until there is substantially nothing more to hold; third, to so provide that pencil ends of slightly varying diameters may be held or clamped equally well inposition; and fourth, to provide that there shall be a minimum of difference in diameter between the holder and the pencil itself, especially in that part in near proximity to the exposed portion of the pencil.

To these ends my invention consists in certain details of construction and novel combinations of parts, as will be more fully set forth hereinafter, and, in order that my invention may be fully understood, I will now proceed to describe pencil holders constituting embodiments thereof, and will then point out the novel features in claims.

In the drawings: Figure 1 is a view in central longitudinal section through a pencil holder constituting an embodiment of my'invention. Fig. 2 is a view in transverse section therethrough, the section being taken upon the plane of the line 2-2 of Fig. 1. Fig. 3 is a view similar to Fig. 1 except that the clamping member and holding tube are fitted together in screwthreaded relation, instead of being merely held together by friction, as in the example shown in Fig. 1. Fig. 4 is a View similar to Fig. 1 showing a slightly modified form of clamping member. Fig. 5 is a transverse sectional view of the same, the line of section being taken upon the plane of the line 55 of Fig. 4.

The pencil holder comprises two elements or members, one the tube 10 by which the device is held in the hand, and the other the clamping member 11 by which the pencil fragment is supported. The clamping member and the holder tube are arranged to be adjusted with relation to each other for the purpose of contracting the clamping member, whereby it will be caused to grasp the pencil fragment firmly. In the example of my invention shown in Fig. l, the clamping member 11 is fitted frictionally within the tube 10, being arranged with a somewhat tight sliding fit. The clamping member 11 is formed with a swelled portion 12 at its forward end, and, further, the tube of which the clamping member is composed is severed for a distance down from the forward end, as at 13, so that such end is formed into spring jaws. The extremity of the tube 10 is arranged to engage the swelled portion 12 at its rear portion, as I shown in the drawings, and, by being pressed firmly against such rear portion, will cause the jaws to contract around the pencil fragment to be held thereby.

In Fig. 3 I have shown a screw-threaded connection 14 whereby the end of the tube 10 may be forced over the swelled portion 12 of the member 11, but in actual practice I have found that a reasonably tight sliding fit is all that is necessary to hold the parts in the position to which they may be adjusted, and that they may be adjusted to the required position simply by being pressed together.

Fig. 4 shows a modification in which the swelled portion is formed by expanding the tube of which the member 11 is composed, as at 15. Greater resilience is thereby given to the portion 15, and the jaws are normally given a tendency to contract. Beyond the portion 15 is a portion 16, which is intended to engage the pencil fragment, and the tube 10 may be similarly pressed firmly against the part 15 in order to clamp the parts in their adjusted position. A pencil holder of the form shown in Fig. 4 will hold any pencil fragment which is long enough to be gripped by the part 16.

What I claim is:

A pencil holder comprising an outer tubular holding element having a cylindrical bore, and an inner tubular clamping element having a cylindrical portion accurately fitted to said bore, said clamping element having a swelled portion near its outer end with which the end of the outer tubular element is adapted to engage, and split for a short distance only at the end at which is the swelled portion, whereby to form contracting jaws.
