BAKER lCOUNTY, OREGON.

PENCIL.

SPECIFICATION forming part of Letters Patent No. 357,063, dated February 1, 1887.

Application led January 19, 1885.

To all whom t may' concern.-

Be it known that I, WILLIAM C. CARLTON; of Baker county, in the State of Oregon, have invented certain new and useful Improvements in Pencil and Crayon Holders and I do herebydeclare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of reference marked thereon, making a part of this specification.

My invention consists in making an iinproved pencil and crayon holder, so constructed that the leadcan be kept as sharp at its point as is requisite for convenient use by simply turning the head of the pencil.

In the drawings, Figure lis an external view of the pencil and crayon holder, showing the shield b for protecting the point of the pencil while it is being carried in the pocket. Fig. 2 is a longitudinal sectional view of, Fig. 1. Figs. 1 and 2 are drawn upon the same scale. All the other figures are drawn upon a uni-A form scale, considerably larger than the scale upon which the first two figures are drawn. Fig. 3 shows the internal construction of the pencil and crayon holder, all of its Outside casing -being removed, except the part C and the outside part of D. Fig. 4 shows all that part of the pencil and crayon holder that is removed from Fig. 3, excepting the shield b. Fig. 5 is a view, looking at its smaller end, of those parts of Fig. 3 that are indicated by the letters P and'n' in Fig. 3. Fig. V6 is a view, looking into the small end, of a section of the left-hand half of Fig. 4, through the line :v fr.

The purpose o1 my invention is to make a lead-pencil convenient for common use, in which the stick of writing-lead is held in place on the inside of the pencil and crayon holder tube, and will be pushed forward ready for use as fast as the point of the lead is worn off. In the drawings, A is the case of the pencil and crayon holder.

b is a hollow shield or shell for covering and protecting the pencil and crayon holder point.

His a small stud fastened in the case A.

g is an inclined slot cut through the shield b. The stud H projects through the slot g 5o and prevents the shield from sliding off from Serial No. 153,302. (No model.)

'the case. The shield will revolve partly ar-ound the case, its movement being controlled and limited by the stud H in the slot g. When the stud is at the upper end of the slot, as shown in Fig. l, the shield will reach below the point of the lead and prevent it from being broken when the pencil and crayon holder is carried in the pocket. lVhen the shield b is turned around, so that the stud H will be at the other cnd of the slot, the incline of the slot will cause the shield to move upwardk on the case, so that its lower endpwill rise above the pencil-point and leave it uncovered in condition for use, as shown in Fig. 2.

n is a tube that extends from the point of the pencil and crayon holder'to the head D.

P is au annular shoulder, that forms a part of the tube n.

The upper end of the part D forms the head of the pencil and crayon holder, while its lower portion is a tube. (Plainly shown in Figs. 2 and 3.) rlhe upper end of the tube portion of head D is partly cut away in Fig. 3. The upper end of the tube n enters and is riveted at D to the tube portion ofD.

L is a collar that slides upon the tube u above the shoulder P.

' J is a coil-spring that loosely surrounds the tube n, as shown.

M is a short bar on the inside of the tube n, vhaving its upper end attached to the collar L bythe stud N. The tube n has a longitudinal slot,l of, in its side,` reaching from the shoulder P to D. The stud lN passes through and works in this slot as .the collar L is madey it is required to put a new writ-ing-lead in the pencil and crayon holder.

The collar L is made to t rather tightly in the case A, opposite the notch S, so that there IOO will be friction enough to force the stud N out of the notch S when the collar L is turned inside of the case.

C is a short tube, that surrounds the upper end of the case A. Its upper end is spread out and fits loosely inside of the converging part of the head of D, as shown in Figs` 2and3.

The parts are made to fit loosely, so that the part D may be revolved without revolving the tube C, while the connection of the parts are such that the part D cannot be 4drawn away from the tube C.

E (shown in Figs. l and l) is a very short stud projecting out from the case A, as shown in Figs. l and 3.

fis a groove cut on the inside of the tube C, to receive the stud E. The groovef turns at a right angle at its upper end, and thus forms a shoulder,by means of which the stud E holds the tube C, and with it the partD and its connections from being drawn endwise away from the case A,except when it is desired to do so.

From the lower end of the case A extends a steel tube, O, which gradually lessens in diameter, as shown in Figs. 2, 4, and 6. The hollow of this tube decreases in size until its diameter where it passes through the point is only as large as it is desired to have the end of the writing-lead when it is ready for use. Close to its point the tube O is made with open sides,and one or more of the edges R of these sides are made very hard and formed so as to cut away the outside of the writing-lead when it is pushed forward and turned aroundinside ofthe cutting-edges, so as to reduce it to the desired size for use. The cutting-edges R are y shown in Figs. 4 and 6.

The lower part of the tube a at n is made square, so as to hold and turn with itself a square stick of writing-lead.

The operation of the pencil and crayon holder is as follows: The tube C is turned so as to let the stud E pass through the groove f, when all ofthe parts shown in Fig. 3,being connected together so as to form but one entire whole, are withdrawn from the case A. The collar L is drawn upward on the tube a until the stud N is turned into and rests in the notch S. A square stick of writing-lead of the proper size is then inserted into the tube n through its square end a. The parts shown in Fig. 3 are then inserted in the case A and fixed in place by means of the tube C, groove j", and stud E. The part D is then turned around, when the friction of the case around the collar L will canse the stud N to disengage Ifrom the notch S, when the coil-spring will force the collar L, stud N, and bai-M, and the stick of writing-lead downward, and thereby the lower end of the lead will be forced against and between the upper part of the cutters R. The head D is then turned and with it, by means of the connected parts shown in Fig. 3,is also turned the writing-lead K. As the lead K is thus turned the cutting-edges R reduce the size of its point, so that, being pressed forward by the action of the coilspring J the point will pass through and protrude fronrthe point ofthe pencil and crayon holder far enough for use, as shown in Fig. 2. As the point of the pencil is worn off the head D is again turned and the operation of reducing-and pushing forward the point of the lead is repeated. This is continued until the lead is so far worn out that a new lead is required.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, 1s-
