EPECIFICATION forming part of Letters Patent No. 744,474, dated November 17, 1903.
Application filed February 26. 1903. Serial No. 145,159. (No model.)
To aZZ whom it may concern.-
Be it known that I, ALBERT E. BUCKING- HAM, a citizen of the United States, residing in East Oakland, county of Alameda, State of California, have invented an Improvement in Pencils; and I hereby declare the following to be a full, clear, and exact description of the same.
My invention relates to improvements in [O pencils of that class having a wooden body and an interior graphite or other marking substance.
In consists in constructing the wooden outer body with an axial interior hole having [5 a slight curve from end to end, so that the graphite or other marking body will be made to conform to this curve, and thus bind sufficiently within the tube to prevent its being moved by ordinary pressure upon the point.
An open slot is made in the side of the outer.
body, and a sleeve surrounding and slidable upon this body has an inwardly-projecting spur or arm, which may be either free or connected with the rear end of the marking substance and by which the latter may be advanced as the point is worn away.
Referring to the accompanying drawings, Figure 1 is a side elevation of my invention. Fig. 2 is a vertical section of same. Fig. 3 is 0 a detail of the sleeve 4, Fig. 1.
In the manufacture of pencils used for marking, writing, &c., it is customary in the cheaper classes of pencils to employ a wooden outer body having a central hole within which 5 a fixed lead graphite orother marking substance is secured, the wooden outer portion being cut away at the point from time to time as the marking substance is worn awayuntil the pencil is entirely used up.
It is the object of my invention to maintain the pencil-body of its full length and to advance the marking portion thereon from time to time as it isworn away, thus maintaining the pencil of the same size and length and convenient to hold in the. hands until finished.
In the construction of my pencil I employ the wooden outer body A, which may be cylindrical, hexagonal, or other suitable or wellknown form. Through the center of this body a hole is made lengthwise of such size as to receive the graphite or plumbago or other marking material, which is usually made cylindrical and of a length about equal to that of the outer body, as shown at 2. A slot 3 is made in one side of the outer body A, extending radially from the surface to the I inner opening, and a ring or sleeve 4 is fitted to slide upon this outer body. This sleeve or ring has a spur or arm 5 projecting into the slot andadapted to engage the inner endof the marking substance, which is slidable within the central tube of the outer body. The arm or spur may either extend behind the movable marking portion or it may be so formed as to clasp or engage this portion; but in either case it acts to move the marker. forward and cause it to project from the end of the outer body A. This outer body is tapered in the usual manner of tapering a penoil, so as to converge in unison with the projecting end of the marking portion, and as fast as this marking portion is worn down it is advanced by sliding the sleeve along the outer body, so that the inner arm pushes the lead or marking portion out to any desired extent.
It will be manifest that if the sleeve and the lead were freely movable it would .be nec essary to apply some stop to prevent the lead being forced back when pressure was applied to mark with its point. In order to overcome this difliculty and to obviate the necessity of any special stop, I have made the central opening, in which the lead is contained, in r the form of an are or curve extending approximately from end to end of the outer body, so that when the lead or other marking substance has been introduced it will acquire the same curvature, and will thus be pressed against sufficiently from time to time to compensate for the wear upon the point.
I am aware that metallic pencils have been made with independent slidable leads and turnably-threaded followers by which the leadsmay be advanced from time to time; but I do not claim, broadly, such a structure.
Vhat I claim, and desire to secure by Letters Patent, is-
1. A pencil consisting of an outer body portion having a hole made through it from end to end; a graphite or other marking body adapted to fit the hole said hole being curved in the direction of its length and said graphite body conforming to said curve whereby it will be pressed against the walls of the hole at different points in its length and be frictionally held; and means for advancing the graphite body through said hole.
2. A pencil consisting of an outer wooden body having a comically-tapered end, a tubular hole made from end to end of said body, said hole being bent or curved between its ends, a graphite or other marking body adapted to fit said hole and cause to bind against the sides thereof by the longitudinal curvature of the hole, a slot extending from end to end of the outer body and open from the interior hole to the outside, a ring or sleeve slidable upon the outside body having an arm or spur extending into the slot and connecting with the rear end of the markingbody whereby the latter may be advanced by pressure upon the ring and retained in any position by frictional contact caused by its curvature from end to end.
V In witness whereof I have hereunto set my hand.
