COMBINATION PENCIL. POINT-PROTECTOR AND SHARPEN EF L SPECIFICATION forming part of Letters Patent No. 661,955, dated November 20, 1900.

Application filed July 9, 1900. $erial No. 22,937. (No modeli) To all whom it may concern.-

Be it known that I, WILLIAM LEFfJvRE CRANSTONE, medical practitioner, a subject of the Queen of Great Britain and Ireland, residing at 1] Victoria street, Melbourne, in the county of Bourke, Golony of Victoria, have invented certain new and useful Improvements in Combination Pocket Pencil Point-Protectors and Sharpeners, of which the following is a specification.

The object of my invention is to provide a combination pocket point-protector and sharpener for pencils which shall not only be cheap in first cost, durable, and light and convenient for the pocket, but which shall also be instantly usable either as a pointprotector or as a sharpener.

My invention consists in the combined combination pencil point-protector and sharpener and in the combination and arrangement of its various parts, substantially as will be hereinafter pointed out, and finally embodied in the claim.

My invention is fully illustrated in the accompanying drawings, wherein- Figure l is a perspective view, partly in section, of my invention shown as attached to a pencil; and Fig. 2 is a View in side elevation, partly in section, of a slight modification of the invention.

In the accompanying drawings, a, designates a light frame which is provided with openings 1) and c at its respective ends, the former being adapted to receive the body of the pencil, while the latter is provided for the admission of the pencil-point. Said frame carries a cutter d, which is arranged therein and secured thereto in the usual manner, and e designates a milled knob forming an integral projection of the frame, said knob being penetrated by the opening 0. The sectional contour of the frame a is preferably circular.

fdesignates a tubular holder, which consists of sheet metal and which comprises a tubular casing g, adapted for the reception of the frame CL, and a slitted sleeve portion it, having a smaller diameter than said casing.

2' designates a slit in the sleeve portion h.

The length of the casing g is greater than that of the frame a-that is to say, the length of said frame as measured from the annular shoulder j to the shoulder thereof. The frame therefore has longitudinal as well as rotary movement in the casing, its longitudinal movement being, however, limited by the abutment Z, formed between the casing and the sleeve portion, and another abutment 1%, formed by turning in the edge at the free end of the casing.

In the modification shown in Fig. 2 the frame a, having the milled knob e and the cutter d, as in the case of the device already described, is of conical form. The end of the frame away from the milled knob consists of a tubular extension n, having its extremity of reduced diameter and turned inwardly, the internal tubular portion 0 of said extension thus formed by turning in the extremity of the extension being flared at its end, so as to form an annular recess p. The internal tubular portion 0 of the extension it receives a sleeve g, which loosely fits therein and which is provided with a slitr, which permits expansibilityin said sleeve, which is thus adapted to snugly fit the body of the pencil, as in the case of the sleeve portion h. In order to prevent the separation of the sleeve from the frame, in which said sleeve has longitudinal movement, its upper end .is provided with an external bead 8, approximately fitting the recess p.

It will be observed that in either of the forms of my invention one of the two independently-movable members of the device receives the other and has an annular recess, as 50, Fig. 1, or p, Fig. 2, in which a shoulder, as 70, Fig. 1, or s, Fig. 2, on said other member is movable. Thus the member which clasps the pencil and which is arranged so as to be conveniently grasped by the hand of the operator may be drawn upon, so as to force the cutter carrying member snugly against the pencil in such manner that no looseness of parts can accrue, as when the device is out of use and serving as the pointprotector.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent, is

In a combined pencil sharpener and pointprotector, the combination of two substantially tubular members projecting the one into the other, one of said members having an annular internal recess and the other having an abutment; projecting into said recess, and one of said members being the cuttercarrying member and the other being expansible and adapted to clasp the pencil, substantially as described.

In witness whereof i have hereunto set; my

hand to this specification in thevpresence of two Witnesses.
