' PENCIL ATTACHMENT.

application filed June 12, 1925. Serial'No. 36,674.

This invention relates to'improvements in devices to be removably applied to ordinary lead pencils, my principal object being to provide an article whose main function is to protect the point of a pencil against breaking when the pencil is not in use or is in the pocket, and which does not need to be removed from the pencil to expose the point of the same for use.

. The point protecting members are so constructed that they'may be used as tweezers.

I have also mounted a file on the attachment which may be used for putting a sharp point on the pencil when the attachment is removed therefrom, or it maybe used as a finger nail file or for any other purpose for which itmay be found suitable. The file is so mounted that it does not interfere with the use of the device as a point protector, and is arranged when not in use to fold so as not to catch in the pocket goods.

A further object of the invention is to produce a simple and inexpensive device and yet one which willbe exceedingly effective for the purpose for whichit is designed.

These objects I accomplish by means of such structure and relative arrangement of parts as will fully appear by a perusal of the following specification and claims.

In the drawings similar characters of reference indicate corresponding parts in the several views:

Fig. 1 is a longitudinal elevation of the attachment.

Fig. 2 is a similar view with the file opened out.

Fig. 3 is a longitudinal section on the line 33 of Fig. 2.

Fig. 4: is a cross section on the line 4-4 of Fig. 2.

Referring now more particularly to the characters of reference on the drawings, the attachment comprises a body, which is v a sleeve-like unit preferably comprising spaced rings or sleeves 1 and 2 connected by opposed arms 3. This unit could be made as a complete sleeve from end to end but the construction shown makes the device lighter. The rings 1 and 2 are split transversely in longitudinal alinement as shown at f and are of spring metal, so as to enable them to' surround and frictionally engage pencils of different diameters.

' Projecting outwardly of the body from the sleeve 1 are opposed spring arms 5 of a suitable length, and provided at their outer ends with inturned portions 6 terminating adjacent each other. The adjacent edges of these portions are preferably sharp so as to enable them to function as a pair of tweezers when the arms 5 are suitably manipulated by a hand.

Pivoted transversely on the sleeve 1 intermediate the arms 5 and extending lengthwise of thebody is a blade 7 having a filing surface 8 on the face thereof adjacent the body. The filing surfaces may be formed on both sides of the blade if desired.

The point of the file normally rests on the sleeve 2, the latter having a countersunk portion 9 to receive the point so that the latter will then lie practically flush with said sleeve.

Turnably mounted on the sleeve 2 is an outer sleeve 10, split transversely so as to follow the expanding and contracting movements of the sleeve 2, and arranged to frictionally engage the latter at all times.

The sleeve 10 is held against longitudinal movement on the sleeve 2 by circular flanges 11 on the latter, between which flanges the sleeve 10 is located. Turning movement of the sleeve 10 on the sleeve 2 is limited by a pin 12 in the latter which projects through a circular slot 13 in the sleeve 10. A recess 14s is out in the sleeve 10 from the edge thereof facing the file, of a sufficient size to receive the point of the file therethrough when said sleeve is turned to aline the recess with said point. The position of the pinion, sleeve 10, and recess 14 are so related to each other that when the sleeve 10 is turned to its limit of movement in one direction, the file point will be concealed under the sleeve, and hence the file cannot then be'swungon its hinge and away from the body. When the sleeve 10 is turned to its limit of movement in the opposite direction, the recess 14 will then aline with the file point, and the file may then be swung on its hinge to expose the filing surface and enable it to lie relative to the body as shown in Figs. 2 and 3. In operation as a pencil point protector the device is slid onto a pencil 15 from the outer end thereof, so that the members 6 lie just outwardly of the point 16 of the pencil. The latter is then of course protected from breaking. Then it is desired to use the pencil the attachment "is simply slid .further along the same to expose the point 16, the arms 5 spring the necessary distance apart as the portions '6 come in contact with the pencil. v

In order to form a rest or support *for the file when the latter is opened out, .the adjacent edges of the arms 5, near their outer ends, are provided with short inwardly projecting lugs or lips 18.

From the foregoingdescription it will be readily 'seen that I have produced such a device as'substantially fulfills the objects of the invention as set forth herein.

\Vhile this specification sets forth in detail the present :and preferred construction of the device, still in practice such deviations from such detail may be resorted to as do not form a departure from the spirit of the invention, as defined by the appended claims.

Having thus described my invention what I claim as new and useful and desire :to secure by Letters Patentis:

1. A pencil attachment including a sleeve 7 'toslide along a pencil, a blade hinged at one end onto the sleeve and extending lengthwise thereof, said blade being arranged to lie folded against the sleeve or to be swnng'out- \vardly therefrom, 'and an extension provided with the sleeve to form a support for the blade adjacent its outer end when said blade is swung outwardly from the sleeve.

A -pencil attachment including a sleeve to slide along a pencil, a blade hinged at one end ontothe'sleeve and extending lengthwise tion, said outer sleeve having a transverse recess opening inwardly from-the edge there- .of facing the blade-end to receive such end.

In testimony whereof I allix my signature.

PETER M. HAMMA-LIAN.
