PEN AND PENCIL HOLDER.

SPECIFICATION forming part of Letters Patent No. 495,784, dated April 18, 1893. Application filed January 26, 1893. Serial No. 459,399. (No model.)

To all whom it may concern.-

Be it known that I, ARTHUR W. COFFIN, a citizen of the United States, residing in the city and county of San Francisco, State of California, have invented an Improvement in Pen and Pencil Holders; and I hereby declare the following to be a-full, clear, and exact description of the same.

My invention relates to a novel pen and pencil holder.

It consists in certain details of. construction which will be more fully explained by reference to the accompanying drawings, in which Figure 1 is a longitudinal section taken through the case showing the parts which are held in the case. Fig. 2 is an enlarged longitudinal section of the central portion taken at right angles with Fig. 1. Fig. 3 is a transverse section. v

A and B are the two parts of a tubular cylindrical case which may be made of hard rubber or other suitable material. In one end of the tube B is fitted the stock 0 which carries the pen D. This stock has an enlarged central flange, and each end is made cylindrical and fits snugly into theend of the tubular case B, so that when one end is introduced into the holder, the pen projects in position to be used, and when introduced in the other.

position, the pen is reversed and protected within the case, as shown in Fig. 1. The outer end of the part A contains an erasing rubber E, or, if desired, a pencil may be introduced. The inner ends of A and B are fitted to slip over the two cylindrical tubular ends F, which project from a central portion G of slightly larger diameter, against which the ends of A and B abut, so that when the whole is put together, it forms a holder and handle for the pen or pencil.

From one of the parts F an erasing knife H projects, and from the other a ruling pen I, and when the parts are put together, as shown in Fig. 1, the eraser and pen are concealed within the tubular holders A and B.

Whenever it is desirable to use either the eraser or the ruling pen, the part A or B which incloses the implement to be used is disengaged, thus leaving the implementexposed for use.

In order to conveniently disengage these cases, I have shown the following construction:'lhe tubular portion F contains a spiral spring J, plainly shown in Fig. 2, and surrounding theshank K of the two implements H and I. The two are put together conveniently by making the larger portion K of the shank hollow and screw-threaded, and the opposite portion K is made of smaller diameter and threaded to fitinto the part K, so that when the two are screwed together, the disks L which surround the bases of the knife and ruling pen respectively, as shown in Figs. 1 and 2, are drawn down against the ends of the parts. F, thus holding the Whole firmly together. The part F has an angular slot,as shown at M, at each end, and pins N which project from the parts K and K extend out through the slots M, and the ends project sufficiently beyond the circumference of the part F so that they engage slots 0 which are made in the adjacent ends of the two parts A and B.

The operation will then be as follows: When either of the ends A or B is removed, the spring J is extended, and the pin N is thrown out until it strikes the disk L. When the part A or B is to be replaced, it is put on so that the slots 0 fit over the ends of the pin N, and by pushing this outer tube A or B toward the center, the pin is forced to travel down the longitudinal part of the slot M until the tube A or B abuts against the central enlarged part G, when a slight turn forces the pin N into the transverse part of the slot M, as shown in Fig. 1, and at the same time a partial screw-thread upon the end of the part G engages acorresponding one in the end of the part A or B, and thus locks the two parts together, holding the spring compressed. Now, if it is desirable to disengage eitherof the ends A or B for the purpose of using the eraser or the ruling pen, it is only necessary to press the thumb or finger upon the part to be removed with a slight twisting motion which will disengage the pin N fromits looking notch, and this releases the spring and allows it to suddenly extend itself until the pin N is in the position shown at the right end of Fig. 2. This sudden motion forces the tubular holder B off, clear of the rest of the implement, and thus leaves the eraser or ruling pen exposed for use, it not being necessary for the user to employ both hands for the purpose of disengaging the inclosing tube, which is sometimes a matter of inconvenience where both hands are employed.

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

1. A pen and pencil holder consisting of the tubular sections A and B having the outer ends adapted to receive a pen or pencil, a central double-ended piece F containing a stock for the eraser and ruling pen which project from its opposite ends, as shown, and a means comprising a pin and slot connection between the ends of the holder and the stock for securing the adjacent ends of the two-part holder upon the opposite ends of said central stock, substantially as herein described.

2. A pen and pencil holder consisting of the tubular holders A and B having the outer ends adapted to receive a reversible pen stock and rubber eraser respectively, a central stock over which the inner ends of the tubes are adapted to fit, said stock carrying an eraser and ruling pen at the opposite ends respectively, so that they are inclosed within the two parts of the pen stock, a spiral spring contained within the central stock, pins projecting from the shanks of the eraser and ruling pen respectively through slots made in the stock, against which pins the spiral spring acts so as to force them outward and disengage the holders at either end, substantially as herein described.

3. A holder consisting of tubes A and B adapted to receive reversible pen stock and erasing rubber at their outer ends respectively, a hollow central stock F, into the opposite ends of which the shanks of an eraser and ruling pen are fitted, a spiral spring surrounding said shanks within the stock F, pins N projecting transversely from said shanks through longitudinal slots M made in the stock so as to be engaged by slots 0 in the inner ends of the partsAand B whereby the spring is compressed when these parts are forced on to the central stock, anda locking device for holding them in place when they are forced on, substantially as herein described.

In witness whereof I have hereunto set my hand.
