PENCIL HOLDER.

Application filed March 16, 1923. Serial No. 625,558.

To all whom it may concern:

Be it known that I, AMBnosn FLEMING, a citizen of the United States, residing at Washington, in the District of Columbia, have, invented a new and useful Pencil Holder, of which the following is a specification.

My invention has reference to improvements to that type of writing devices that have a magazine or other like container for holding a number of extra leads, whereby to provide for readily supplying a new lead, after the prior placed lead is worn out or becomes broken, and my said invention primarily seeksto provide a pencil, ever ready for use, of a simple and inexpensive construction, in which the several parts are so designed and relatively arranged whereby they can be readily assembled for use, and the operation of placing a new lead and 2 feeding it forward, as it is used up, can be positively effected without disconnecting the said parts. f

My invention further has for its object to provide a pencil of the general type stated in which the casing may be of some length whereby to provide for using relatively long leads, within which a magazine of peculiar design `is provided in which a number of longY leads may be collectively stored and held for being easily and positively dropped into a receiver, in proper position for writing, and which has simple provision to allow for advancing the writing end of the leads, progressively, and for securely sustaining the leads in their progressively advanced positions.

Another and essential object of my present invention is to provide a pencil holder of the character stated, in which a large number of extra leads vof i considerable length are so held, that, by a simple turning of a finger operated knob at the butt end of the holder, the leads are positively and automatically caused to drop, one at a time, into a receiver which holds the dropped pencil lead in proper position for being projected through the point of the casing to the desired writing position.

lVith other objects in View that will be,

hereinafter explained, my invention comprehends an improved multiplepencil lead holder that embodies the peculiar features of construction and novel arrangement of parts, stated in the following detailed description, specifically pointed out in the appended claim and illustratedin the accompanying drawings, in which:

Figure l is a side elevation of a pencil holder that embodies a preferred construction of my invention.

Figure 2 is a longitudinal section thereof, a lead being shown in the writing position, other of the magazine leads being also shown.

Figure 3 is a cross section, on an enlarged scale, of the preferred construction, taken on the line 3-3 on Figure 2.

Figure t is a detail perspective view, on an enlarged scale, of the forward end of the leads holder or magazine and the outermost or lead gripping end of the adjustable lead receiver hereinafter specifically referred to.

Figure 5 is a similar view of the knob equipped end of the said receiver and illustrates the screw fed stud and detent for holding the receiver from being freely withdrawn from the casing.

Figure 6 is an enlarged detail section of' the internally threaded end of the casing with which the parts shown in Figure 5 coaot.

In my present invention, as outlined in the preferred construction thereof, Figures l to 6, the helder consists of an outer casing l preferably of the length of an ordinary fountain pen or similar types of writing pens and the said casing includes the usual tapered'end member l0 that is provided with a central pencil point passage 10u.

In the construction shown in Figures l and 2, the tapered end l0 is a solid member formed with a central bore 1l that vtapers towards its front end, as indicated at ll, where it merges with the point passage l0, the reason for which will presently appear.

At the inner end, the member l0 has a threaded hub l2 for screwinginto the internally threaded outer end of the casing l so as to provide for readily disconnecting the said end to admit of loading the magazine from the front end of the casing, as presently further explained.

In the preferred construction of my pencil holder, as illustrated in Figures l to 6, is included a simple and cheaply made leads carrying magazine 2, which is contained' within the casing l and from lwhich the leads are caused to drop, individually and successively, as the parts constituting the holder are finger manipulated in themanner presently explained.

The magazine 2 is made by taking a thin blank sheet of resilient metal and bending it into tubular shape, with one of the meeting edges turned inwardly to form a radial stop flange 2O against which the opposing edge of the bent tube closes, as is clearly shown in Figure 3.

The lead receiver and control device hereinbefore referred to in the preferred construction, consists of a tubular member 3, the forward end of which is slitted longitudinally, as at 3G-"20, whereby to provide spring clamps for gripping the leads as they are individually projected through the forward end of the tubular lead receiver and the point passage in the tapered front end of the casing.

Fixedly joined with the rear end of the member 3 is a hub 3l that has a radially projected stud 32 near its inner vend and whose outer end terminates in the linger or turning knob 83, as is best shown in Figure 2, by reference to which it will be seen that the hub 3l turns within the internally threaded portion of the casing l, the threads of which lare of a slow pitch and straight for operatively receiving therein the stud 82, the latter and the threads constituting the means for holding the receiver in operative connection with the magazine and from being freely withdrawn from within the said casing and magazine, the screw and stud connections also serving as the means for feeding the receiver forward, whereby to cause the spring clamps, at the forward split end thereof, to engage and wedge between the tapered front end of the bore 11a within the solid tapered end of the casing to cause the said clamps to firmly grip a lead that has been projected through the forward end of the receiver and the casing passage 10a.

As will be noticed, by reference to Figure 2, the split end of the tube 8, at all times, rests and has bearing in the axial bore of the solid tapered front end of the casing and from the inner end of the said casing member and to the internally threaded portion of the said casing, the tubular receiver is cut away, as at 35, whereby to form it into a trough-like portion of a length at least as long as the lead the receiver is to hold.

It should be stated, the screw feed of the receiver in the direction of the length of the casing is suflicient to set the receiver 3 so that its trough or opened portion may be readily brought into register with the pen- "cil lead, so that a slight turning of the receiver in the direction of the arrow m, will bring the said member 3 in line to receive the foremost lead, (i, that is, the one next to the stop 20, so that, by simply turning the hol der until the lead a is uppermost,the receiver being empty, the said lead will drop its full length into the receiver, it being understood the remaining leads within the casing will be held in annular relation with respect to the member 3, since the latter constitutes an axial bearing for supporting the leads in that position.

After a lead is dropped into the receiver, the holder is turned to the vertical position, which causes the point end of the pencil lead to slide into the split end of the tube 3, it being obvious that, by slightly tapping or giving the holder short jerks, in the direction of its length, the lead within the receiver will be forced through the front end of the tube and through the passage lOfL in the casing end and, when thus projected, the point end may be pushed out to the desired writing position, and, when thus set, it can be firmly held to the said position by further turning of the knob to feed thc receiver forwardly and thereby, by reason of the split ends of the tube engaging the tapered portion of the bore ll, as before stated, the ends of the tube will be caused. to clamp the lead.

The member 3, after receiving the lead, has suflicient forward adjustment effected by the screw feed to move the solid portion of the tube to pass bieyond the outer ends of the leads still in the magaine, thereby holding them positively against any tendency to crowd into the receiver and become broken.

Tendency of the forward or pointed end of any of the eXtra leads to drop into and become clogged within the receiver 3, when a lead is held in said receiver (see Figure 2), is overcome by reason of the Said front end of the lead being held up by engaging the lead within the receiver and the tendency of the rounded edges of the slotway 35 to roll the said front end of the magazine lead up and in position for riding on the solid or trough part of the member 3, as the same member is turned to position its slot-way 35 out of alignment with the lead a held against the magazine stop flange 20.

Providing a pencil holder constructed and j described and as illustrated in Figures l to 6 of the drawings, presents a very simple and practical multiple lead pencil holdei` in which the operation of feeding a new lead into the writing position can be positively and quickly effected without the separation of any of the parts of the holder, all that is necessary to place a new lead in position is to turn the knob 33 in reverse direction, whereby to pull back the receiver 3 until its slotway 35 is in register with the length of the lead in the magazine.

Ry then turning ,the knob clockwise to cause the slot way to come under the magaine held lead a, neXt the stop 20, the said. lead will drop, its full length, into the receiver.

By then giving the holder sudden jerks, in the direction of its length, the lead within the receiver will be caused to project through the front tapered end of the casing and, after adjusting the said end in condition for writing, by further turning the knob 33, forwardly, the relatively slow screw feed at the butt end of the holder, will cause the receiver to feed longitudinally forward and thereby cause the clamping portions, at the front end thereof, to engage and become wedged in the tapered portion 11a of the bore 1l in the casing end l0 and grip the lead.

To refill the magazine, it is only necessary to unscrew the casing end 10, turn the casing with the open end uppermost and slide Y the leads lengthwise` into the magazine.

To facilitate the removal of the receiver 3, with its hub and knob portion, the screwway in the butt end of the casing terminates in a longitudinal groove a that opens through the said butt end of the casing to permit of pulling out the stud 32, when fed back and turned into alignment with such groove.

What I claim is:

A pencil holder comprising a casing having a lead passage in its forward end, a pencil lead receiver axially insertable within the casing and having clutch portions at the forward end for cooperating with the delivery end of the casing, whereby to grip the leads projected from .the receiver through the casing end, and a magazine into which the leads are endwise insertable, the said magazine having elements for sustaining the leads therein in annular relation around the receiver, when the said magazine is inserted into and fiXedly held within the casing, the said casing with the magazine and the receiver being relatively rotatable, whereby to bring a selected one of the magazine leads into position for falling, its full length, into the receiver and means adapted, under relative rotation of the casing and the receiver for clamping the selected pencil lead in the front end of the casing, the said magazine consisting of a resilient metal plate bent to tubular shape with one of its meeting edges bent, its full length, radially inward to constitute a stop against which the leads held in annular relation within t-he casing can be successively fed, the said tubular magazine being insertable into one end of the casing and held, under frictional contact, in rigid connection therewith.
