PENCIL-TIP.

SPECIFICATION forming' part of Letters Patent N o. 703,721, dated July 1, 1902.

i Application tiled December 13, 1901. Serial, No. 85,795. (No model.)

T0 a/ZZ whom/ it may concern.:

Be it known that I, LOTHAR W. FABER, a

citizen of the United States, residing at the split and adapted to receive andvhold a rubber eraser, and a sleeve or tube one end of which fits over the thirnble upon the pencil and the other end receives the split thimble and erasing-rubber-the parts being preferably made from thin sheet metal. The thirnble or sleeve tting upon one end of the pencil may be removable or fixed and if removable is advantageously split to be yielding.

In the drawings, Figure l represents a pencil broken and fitted with my improved tip, showing the parts thereof detached. Fig. 2 is a general elevation showing the parts assembled. Fig. 3 is a longitudinal section showing the parts detached and in substantially the samerelation shown in Fig. 1. Fig. 4 embraces a modification of my improved pencil-tip.

In Figs. I, 2, and 3,-a represents a pencil, to

the end of which a thiinble b, of sheet metal, is attached in any desired manner, preferably by being forced over a reducediend. The

surface of this thimble b is preferably provided at about its central 'portion .Witha roughened surface, preferably a series of longitudinal serrations or corrugations b', circumferentially disposed, and the end 2 of the thimble b, which abuts against a shoulder on the pencil, may be turned over or flanged or made heavier than the thimble-tube.

c representsa second thimble similar to the thimble b in that it is provided with a Toughened-portion or serrations c and one` 4end 4 thereof made heavier than the thimblef The thimble c, however, is wholly or.

tube. partially split or longitudinally divided on one sid-e, as at, and is adapted to receive and hold a rubber eraser d, the position of which is adjustable therein.

e represents a sleeve also preferably made of sheet metal, Whose inside diameter is approximately the same as the outside diameter lof the said thirnbles. The ends of the said tube are thus adapted to lreceive the said thimbls, the corrugations on the thimbles binding against the inner 'surface of the sleeve e and not only holding the parts together, but keeping the rubber eraser d held by friction and compression in any desired adjusted position.

The thimble b is conveniently furnished With every pencil, While the split thimble c, eraser d, and sleeve e are interchangeable with all pencils of the same diameter having the same-sized thimble fitted thereto. In 'assembling the tip the sleeve e is fitted over the thimble on the pencil and the other thimble pressed into the opposite end of the sleeve and the parts pressed together until the ends of the sleeve abut against the enlarged ends 2 and 4 of the respective thimbles.

As the position of the erasing-rubber is adjustable in the split thimble, it will be readily apparent that With this construction the rubber when not in use .may be so Jplaced in the split thimble that when the said thimble is inserted inthe sleeve the rubber Will be completely incased and protected down in the thimble and away from possible contact With substances that would be liable to soil the rubber. y

In Fig. t I have illustrated a modification of myinvention wherein instead of securing a roughenedTsurface thimble to the end of which allows it to be'adjustable to any position along the length of the pencil. The sleeve c used with this form is precisely simi,- lar to the sleeve hereinbefore described, but may be advantageously somewhat longer, and the thirnble -c for receiving and holding the erasing-rubber may-be only partially split on opposite sides, as shown in Fig. et. By this construction the pencil-point may also be pro` tected When not in use by reversing the pencil and inserting the pointed end lwithin the IIGO sleeve e, it being understood that the pressure between the sleeve e and the portions b ofthe sleevefcauses the latter to bind the pencil suiiciently tight to hold the same in any desired position. With this modified structure it is possible to utilize short lengths of pencils, as the combined length of the parts is ample for the grasp of the lingers in Writing.

I claim as my invention- The combination with a pencil, reduced in diameter' at one end, of a tubular metal part fitting and secured upon the reduced end thereof and having a circumferential rib and a partially raised or roughened surface, a

LOTI-IAR W. FABER.
