IMPROVEMENT IN PEN AND PENCIL CASES.

.To all whom t may concern:

Be it known that l, JOHN RICHARDSON, of the city, county, and State of New York, have invented certain new and useful Improvements in Pen and Pencil Cases, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings of the same, making part of this specification, and in which- Figure l represents my improved pen and pencil case closed or shut up into the most compact form. Fig. 2 represents a view with the case extended and the pen protruded. Fig. 3 represents the pencil protruded and the lower part of the case removed to expose the interior parts. Fig. 4t represents a similar view with the pen-holder extended. Fig. 5 represents the pen and pencil retracted, as in Fig. l, and the lower part of the case removed to show the pencil locked in the case while the pen is free to be protruded. Fig. 6 represents a similar View with the pen-holder locked to the case and the pencil free to be protruded. Fig. 7 represents a longitudinal Vsection of the case extended and the pencil protruded. Fig. 8 represents a side view of the frame and turning-tube. Fig. 9 represents views of the pencil-holder in different positions. Fig. 10 represents views of the pen-holder in different positions; and Fig. 1l represents an end and sectional View of the sliding ferrule.

This instrument consists of several parts. One, which I shall call the frame, has the relative position of its members iixed. The remaining parts are movable in various ways within denite limits and are supported, connected, and maintained in place bythe frame.

The frame consists of a small tube a, on the upper end of which a second tube b of larger diameter is soldered. The small tube a has a slot c in its lower half, the object of which is to guide and limit the range of Inotion of the pencil-holder CZ, which slides with in this tube. The upper end of this slot is enlarged to double the width of the lower part in order that the guide-pin which traverses the slot may have room to turn at this point laterally to permit the pencil-holder to be partially turned on its axis to bring its driver e into or out of gear with a slide by which it is protruded from and withdrawn construction.

into the frame. The upper half of the small tube a is perforated with two parallel slots f, connected at their lower end by a cross-slot. This cross-slot permits a pin g, carried by a tube h, to turn the drivers of the pen and pencil alternately into gear with the slide by which they are protruded and retracted, and the longitudinal slots f permit the tube h and upper end of the case and mounting which it carries to be extended and contracted in the manner of a telescope, for the purpose of elongating the case and rendering it more convenient to write with.

The lower half of the small tube a has a rib t' on its outside parallel to the slots and extending from the lower end of the tube to within a short distance of the lower end of the large tube b, the space or notch j between the upper extremity of the rib and the lower end of the tube being for the purpose of receiving a projection or detent on the drivers of the pen and pencil alternately, so that when the pen is protruded the pencil may be securely held in, and vice versa.

Fig. 6 shows the detenta of the pen behind the stop or in the notehj and the pencil free to slide in and out.

Fig. 5 shows the detent n of the pencil in the notch j and the pen free to slide in and ont. A silver tube, which forms the outside of the case, is placed over thelower end of the frame and attached to the rib7 this outer case and the tube a being concentric and leaving an annular space s, Fig. 7, for the pen to work in while the pencil works within the inner tube.

The pencil consists of a point o anda feeding-screw inclosed in a case d of the` usual The case of the feeding-screw has a rib e attached to it of such a width that it will pass through the slot c of the inner tube a. The upper part of this rib projects beyond the upper end of the feed-screw case d, and also projects laterally to one side for a width and length equal to the detent-notchj, into which it can turn whenever the neck e' of the rib is opposite the enlarged upper part of the slot. In this way the projection acts as a detent to hold the pencil from slipping out of the barrel. The opposite side of this projection has two notches r and r formed in it, the one r to engage with the pin Z, Fig. 11, of the slide m whenever the detent is turned turning the pencil to engage it With or disengage it from the slide m.

The relative position of the driver,notches r and c, and the adjusting and slide pins is shown in Fig. 6, where the pencil is in the proper position to be protruded and the pen is locked fast.

The pen-holder is tubular, and for a length equal to the detent-notch j is about threefourths of a cylinder, or, more exactly, is the complement of so much of the tube or cylinder as is not occupied by the upper part of the rib e on the pencil-holder. The diameter of the inside of the pen-holder tube is equal to the external diameter of the tube a, on which it slides, and the outside of the ribz' is of equal radius and of the form of a stave of the same cylinder.- That part of the penholder below7 the notch is made narrower than the upper part, in order that the upper part n may be free' to turn into and out of the detent-notch to hold and release the pen and at the same time to disengage and engage the notch n in from the slide-pin m. The notch o is for the adjustingpin to act against.

The notches U and t in the pen-holder are opposite thecorresponding notches r and fr in the pencil-holder, so that when the two holders are turned from left to right, or vice versathe notch of one will be disengaged from the pin of the side and that of the other engaged therewith, and when the adjusting-pin is turned to the left when the pen and pencil are both retracted it will disengage the detent n of the pen-holder from the notch j and engage the detent n of the pencil-holder therewith, while at the same time it will disengago the notch fr of the pencil-holder from the slide and engage the notch that b y turning the adj Listing-pin g either of the notches of the driver can be made to embrace the sliding pin l. The adjusting-pin is attached to the lower or inner end of the case h for carrying spare pencil-leads, which is a cylindrical tube closed at the lower end and of such diameter that it will tit into and slide easily within the tube a. The upper end of this tube 7L has a collar 0c attached to it, on which a perforated disk w is fitted, so that it will easily turn. Above this collar and leaving a space to form a groove wide enough for the disk to turn in is a short piece of tube with a screw-thread on its outside upon which the cap 7c tits. A tube q, of such a size that it will slide freely over the tube p, is attached by its upper end to the disk w, its lower end extending over the tube p far enough to prevent it from being drawn Oft the same when the case is extended to the utmost by drawing the pin g to the upper extremity -ot the slots f.

These slots are so placed that one is opposite the adjusting-pin g when it is turned to the proper position to engage the pen-holder with the slide-pin, andthe other is opposite the adjusting-pin when it is turned to the proper place to engage the pencil-holder with the slide-pin, so that whether the pen or pencil be protruded the case can at the same time be extended.

As the relative positions of the parts with the pen or pencil protruded or retracted, and with the case contracted or extended, are so fully shown in the drawings, further description is deemed unnecessary.

If it is not desired to make the case to extend and contract, the slots fare omitted, but the t-ransverse slot is still necessary in order to allow the adjusting-pin to move laterally to bring the pencil and pen alternately into connection with the sliding Jerrule, by means of which they are protruded and retracted.

Having thus described my improved pen and pencil case, what I claim therein as new, and desire to secure by Letters Patent, is-

The combination of the adjusting-pin g, arranged and operating, as described, with the pen and pencil holders and the sliding ferrule for moving them in and out, arranged and operating substantially as described.

2. The parallel slots f and f in the frame, in combination with the adjusting-pin, as described, whereby the holder maybe increased and diminished in length by extending and contracting its upper end, as described.

In testimony whereof I have hereunto subscribed my name.

JOHN RICHARDSON.
