To all whom t may concern.'

Be it known that I, HENRY Hess, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Pencils, of which the following is a specification, reference being had therein t0 the accompanying drawing.

ThisA invention relates to that class of pencils in which the marking lead or crayon is inclosed in a exible sheet such as parchment paper and the like, wrapped therearound to produce a stiff holding roll or body. In such pencils the inclosing sheet is usually provided with parallel weakened lines, and it is so applied to the lead that these lines will extend diagonally or spirally thereof, whereby the spiral sections or strips vbetween the weakened lines may be removed successively to expose fresh portions of the lead as it becomes worn down in use. It is customary to forni holes in the sheet near its outer edge at intervals corresponding to the weakened lines, to facilitate the separation of the outer ends of the sections from each other, this separation being eected by cutting or tearing through the intact portion of the section between adjacent holes, by means of a sharp pointed instrument such as a knife, pin or the like.

The aim of my invention is to enable the sections or strips to be readily unwound, without requiring the use of a tool to start the operation, and with this end in view my invention consists in a novel formation and construction of the inclosing sheet, as a re'` sult of which the spiral sections or strips between the weakenedv lines will terminate at their outer ends in free lips, over which lips is applied a Alongitudinal protector strip cemented down on the sheet at intervals beyond the lips, which strip is adapted to be removed in sections to expose the respective lips beneath. As a result of this construction and arrangement it will not be necessary to employ a tool or instrument in separating the spiral sections when they are to be removed, it being but necessary to grasp the free uncemented portion of the protector strip and tear off a section of the same, which will expose the free lip of the section beneath, ywhich lip may be grasped by the iingers, the spiral unwound, and a fresh portion of the marking lead exposed for use.

In the accompanying drawings:

Figure l is an elevation of a pencil having my invention embodied therein.

Fig. 2 is a similar view showing a section of the protector strip removed to expose the free lip of the spiral section which is to be removed.

Fig. 3 is an elevation of the inclosing wrapper or sheet constructed in accordance with my invention.

Fig. l is a similar view of the protector strip.

Referring to the drawings:

l represents a marking lead or crayon which in the present instance is in the form of an integral lead or body such as is commonly employed in pencils, although this lead may be other forms well known in this art. The lead is inclosed in a built-up body consisting in the present instance of a sheet 2 of fiexible material such as parchment paper or the like, which sheet is provided with a series of parallel weakened lines 2 and which sheet is wrapped tightly around the lead in successive coils, with the weakened lines extending diagonally of the lead and spirally therearound, the outer end of the sheet being cemented down or otherwise fastened to prevent unwinding. In the use of such pencils the spiral sections 2b between the weakened lines are removed in succession to expose fresh portions of the marking lead when the point of the latter becomes worn down in use, the removal of a section being effected by first separating its outer end from the adjoining section and then unwinding and separating it along the weakened line.

In order to enable this operation to be readily performed wholly by the lingers and without the employment of a knife or other implement or tool, I propose, in accordance with my invention, to form the outer end of the sheet in such manner that when the latter is wrapped around the lead to form the inclosing body or roll the spiral sections or strips between the weakened lines will terminate in free lips, which may be readily grasped between the fingers and the sections unwound and separated in succession from the adjacent sections. To effect this object,-

the sheet near its outer end is formed as shown in Ilig. 3 with al longitudinally eX- tending slot 3, the edges of which are formed with pointed notches 4 at intervals corresponding to the weakened lines 2, As a result of this construction, the spiral sections or strips between the weakened lines will terminate in lips 5. In winding the sheet on the lead, it is applied to the latter as'shown in Fig. 3 with the weakened lines extending diagonally of the lead, and when completely wound as shown in Fig. l, the end of the sheet is cemented or otherwise suitably fastened down to prevent. the same from unwinding. This will leave the lips 5 at the ends of the sections free and ready to be grasped between the fingers. Applied over the lips 5 to protect the same against accidental displacement in the use of the pencil, is a longitudinally extending protector strip 6 which is preferably of paper and of such form and so applied that it may be removed by the lingers in successive sections to expose the respective lips 5 beneath. This strip in the present instance is of the form shown more particularly in Fig. 4, where it will be seen that its opposite edges are curved outwardly at intervals as at 6, thereby produc-ing a series of sections 6b connected together end to end by reduced necks 6C which are preferably weakened, as by a perforation 6d, to facilitate the separation of one sec-tion from the neXt. The sections 6b are of a length corresponding to the width of the spiral sections 2b, and in the application of the strip the sections 6b are cemented down on the sections 2b at opposite sides of the slot 3 at points beyond the lips 5 as indicated at 7, thereby leaving the lips 5 free and disconnected from the protector strip,

but covered and protected thereby. Along the inner edges of the cemented areas, the sections of the protector strip are formed with weakened lines such as the perforations 8 to facilitate their separation at the-se points from the sections 2b.

In the complete pencil shown in Fig. l, the end of the foremost section of the protector strip is free and disconnected and constitutes in effect a lip 9 which when a fresh portion of the lead is to be exposed by the removal of the inclosing spiral section, is grasped between the ngers and pulled outwardly. This will cause the uncemented portion of the protector section to separate from the cemented portion along the perforations 8, and will cause the end of the section to separate from the next at the weakened neck 6c, thereby leaving the end of the neck 6c on the next section free. On the removal of the section of the protector as described, the free lip 5 on the end of the foremost spiral section will be exposed and may be readily grasped between the fingers and unwound from the lead, the spiral secnaeaeoe tion in this operation separating from the nekt along the intervening weakened line 2a. This will expose a fresh portion of the lead, and will leave the reduced neck 6C of the next protector section ready to be grasped in the operation of removing the nekt spiral to expose a further portion of the lead.

It will be seen therefore that the removal of the several spiral sections may be performed with facility and wholly by the fingers and without the employment of a knife, pin or other implement as has heretofore been practised.

The protector strip serves in addition to the function described, as a means of holding that edge of the sheet at the inner limit of the slot 3 in place, since the protector strip forms in effect a connection between the outer end of the sheet where it is cemented down in place, and the edge of the sheet at the opposite side of the slot, hence the edge of the sheet bearing the lips 5 will be held in place and prevented fromy unwinding without the necessity of cementing this edge down which would interfere with the unwinding of the sections.

In the foregoing description and accompanying drawings I have disclosed my invention in the detailed form and specific construction which I prefer to adopt, but 'it will be understood that various changes such as will suggest themselves to those skilled in the art may be made without departing from the limits of my invention; and further it will be understood that the invention is not limited to any particular form or construction of the parts except in so far as such limitations are specified in the claims.

Having thus described my invention, what I claim is:

l. In a pencil, the combination of a marking lead, a roll of iiexiblematerial inclosing the same and consisting of separable sections adapted to be removed in succession to expose fresh portions of the lead, said sections terminating at their ends in free lips adapted to be grasped in eecting the separation of the sections, and a protector covering applied over the lips and adapted to be removed to expose the same.

2. In a pencil, the combination of a marking lead, a roll of flexible material inclosing the same and consisting of separable sections adapted to be removed in succession to expose fresh portions of the lead, said sections terminating at their ends in free lips adapted to be grasped in eecting the separation of the sections, and a protector strip applied over the lips and adapted to be removed in sections to expose the respective lips.

3. In a pencil, the combination of a mark- 'ing lead, a roll of flexible material inclosing the same and provided with weakened lines to permit the sections between the lines to be removed, said sections terminating at their outer ends in lips, and a protector strip consisting of separable sections cemented to the first mentioned sections at points beyond the said lips thereby leaving the latter disconnected from the protector strip; whereby the sections of the protector strip may be removed to expose the lips beneath.

4. In a pencil, the combination of a marking lead, a roll of liexible material inclosing the same and formed near its outer end with a longitudinally extending slot, the said roll being provided with weakened lines eXtendino from said slot and forming separable sections adapted to be removed to expose fresh portions of the lead, and the said slot being formed with V-shaped recesses coincident with the weakened lines, whereby the outer ends of the sections will Copies oi this patent may be obtained for terminate in free lips, and a protector covering applied over the lips and being removable in sections to expose the respective lips.
