This invention relates to improvements in lead pencil pointers or Sharpeners, designed for use in drafting rooms, offices, schools,` and the like, and has for its object to provide a relatively small oblong flat wood or metal body having a hand-grip at one end, the opposite end portion thereof being bent downwardly and receiving in its bight a roll comprised of emery-cloth, sand-paper or other strip abradant, which may be unwound and extended, with the abrading surface facing upwardly, over the bend and the plane top of the body towards the hand-grip, and over which the dull tapered ends of pencils may be maneuvered for abrading and pointing said ends; the free end of the abrading strip being passed beneath a transversely arranged clip or guard, having a sharp edge, and being so disposed as to hold the abrading portion from endwise or lateral shifting during the pointing operations; the free end of said strip preferably protruding beyond the clip to enable the operator, from time to time, to grasp and pull the worn-out portions of the strip through the clip, whereby to move fresh stretches'of the strip towards the pointing position, and to finally sever or detach the worn portions by means of said sharp edge by a lateral stroke of his hand. And a further object is to provide a novel and simple support for the abrading roll consisting of a forked spring holder, between whose arms the roll may be rotatably and detachably disposed, the said holder being secured to the bottom face of the body and eX- erting its tension for normally holding the roll in constant frictional engagement with the concave surface of the bend, to prevent creeping or shifting of the abrading tape in any direction, during the pointing operations, or ordinary handling o-f the device.

The various features and parts of the invention will be understood from the detailed description which follows, and by reference to the accompanying drawing, in which- Figure 1 is a top plan of the complete device. Fig. 2 is a side elevation of the same. Fig. 3 is a detached plan view of the roll and holder. Fig. 4 is a fragmentary central vertical longitudinal section, taken on line 4-4 of. Fig. 3. And Fig. 5 is a plan view of the blank from which the clips of Figs. 1 and 2 are formed.

In the drawing, 2 represents the substantially flat oblong body of the pencil pointer, having at one end an integral hand-grip 3, the opposite end portion thereof being formed with a downwardly facing quarter-bend 4, having a bight 4', in which is disposed a roll 5 composed of relatively light gauge or weight emery-cloth, sandpaper, Aloxite or other abradant in the form of a relative long flexible strip or tape 5', which may be wound upon a cylindrical wooden o-r 4other core 6 having aligning axial sockets 5', to facilitate rotatably mounting said roll between the resilient arms 'l of a forked spring holder 8, the said arms being formed with inwardly facing gudgeons l', that snap into said sockets, and being held in place by the opposing tension of the arms. The holder 8 is preferably made of vspring wire which is folded upon itself to pro-v vide arms (l) of'equal length, a portion of said fold comprising a narrow loop 9, which may be expanded laterally, as at 9', to receive a rivet or other fastener I0, by which the loop may be permanently clamped to the bottom face of the body 2, and exert the combined tension of the two arms for normally holding the roll 5 in constant frictional engagement with the concave surface of the bend 4, to obviate creeping or shifting of the tape 5 in any direction, during the pointing operations, or the ordinary handling of the device. In practice, the lateral tension of the free ends of the arms 'l is exerted in4 the direction of the axis of the roll 5, and therefore acts as a brake to prevent accidental recoil of the roll. After the roll 5 is placed in the position shown in Figs. 1 and 2, the operator unwinds the free end portion of the tape 5' and extends the same with the abrading surface facing upwardly over the bend l and the plane top of the body 2 towards the hand-grip 3, and over which the dull tapered ends of the lead pencils maybe maneuvered for abrading and pointing said ends. The act of disposing the tape 5 in the operative position, shown at :I: in Figs. 1 and 2, disposes its free end beneath a transversely arranged clip or guard l2, having a sharp edge I2 facing the handle 3; the clip being so disposed as to hold the abrading portion :u from recoiling, as well as shifting laterally during the pointing. operations. To remove or discard the worn-out portions and substitute fresh portions of the strip 5', the operator may manually `rotate the roll 5 for paying off fresh tape until the free end of the tape extends beyond the clip, as shown in dotted .lines 'n1 Figs. l and 2. This will enable him to grasp and pull the protruding end outwardly until the entire used portion is replaced by fresh abrading tape. He may then conclude the renewing operation by severing and detaching the wornout portion by means of the sharp edge I2', by `a ysimple lateral stroke of his hand. This will again leave the free end of the tape ush with the edge l2 as shown by full lines in Figs. 1 and 2, where it will remain until another stretch becomes Worn out, and so on. The tape 5' of roll 5 may comprise a single strip measuring from two to three feet in length.

Having thus described my invention, what I claim isl. In a lead pencil pointer, an oblong body having a plane top lying between a hand-grip and a downwardly facing quarter-bend, a roll of abrading tape disposed in the bight of the bend, its loose end adapted to be unwound and extended around the bend and over said top, the latter constituting the pencil abrading surface, a clip to engage and gua-rd said loose end, a forked spring member rigid to the bottom of the body to rotatably support the roll in frictional engagement with the concave surface of the bend, the tension of the arms of said member acting as a brake to prevent recoil of the roll.

2. A pencil pointer comprising an oblong body having a plane top lying between an integral hand-grip and a downwardly facing quarterbend, a roll of abrading tape disposed in the bend and engaging its concave surface, the loose end portion of the tape adapted when unwound to be stretched around the bend and over said top, a clip embracing the body adjacent the hand-grip to conne said loose end during the pointing operations, a forked spring member rigid to the bottom face of the body adapted to rotatably and resiliently support the roll between its arms and resist the recoil of the roll.

3. A lead pencil pointer including an oblong body having a plane top lying between an integral hand-grip and an integral downward bend, a roll of abrading tape disposed in said bend, its loose end portion adapted when unwound to be stretched over the bend and said plane top, and being confined and held in operative position by a clip that embraces the body, a spring member rigid to the bottom face of the body having spaced arms to receive and resiliently grip the ends of the roll to prevent accidental recoil of the tape, and said arms exerting their tension to normally hold the roll in frictional contact with the concave surface of said bend.

4. A lead pencil pointer comprising an oblong body having a plane top lying between a handgrip and a downwardly facing bend, a roll of abrading tape disposed in the bend below the plane of the top, the loose end adapted to be unwound and to overlie said bend and said top, a clip embracing the body and the loose end adjacent the hand-grip to prevent lateral shifting of said end during the pointing operations, a forked member secured to the bottom face of the body resiliently and rotatably supporting the roll in contact with the concave surface of the bend to resist recoil of the roll and creeping of the tape, and means to sever the worn-out portions of the tape.
