PENClL-SHARP'ENER.

Specification of Letters Patent.

Patented Dec. 5, 1 5.

To all whom it vnctg concern:

Be it known that I, JAMES T. HIGGINS, a citizen of the United States, residing at New Brunswick, in the county of MiddleseX and.

State of New Jersey, have invented new and useful Improvements in Pencil-Sharpeners, of which the following is a specification.

My invention relates to pencil-sharpeners; and its primary object is to provide a new and useful device of this character wherein the block carrying the end of the pencil to be sharpened and the member carrying the sharpening element or knife arev arranged for simultaneous adjustment to accommodate for pencils of varying size and to provide novel means for effecting the adjustment of said elements.

A further object of the invention is to provide a pencil-sharpener by means of which a pencil may be sharpened without liability of breaking the lead of the pencil during the operation of sharpening, one which is cheap to manufacture, easily operated, durable and efficient, and one which is composed of few parts, so arranged and constructed as not to be liable to become broken or inoperative.

The invention consists in the construction, combination, and arrangement of parts hereinafter fully described, claimed, and illustrated in the accompanying drawings, which disclose the preferred embodiment of my invention, and in which I Figure 1 is a perspective view of a pencil: sharpener constructed in accordance with my invention. Fig. 2 is a central longitudinal sectional view thereof Fig. 3 is a top 7 plan view. Fig. 4 is a top plan view with the knife-carrying member removed. Fig.5 is a detail perspective view of the knife-carrying member. Fig. 6 is asimilar view of the bracket carrying a block adapted to support the end of the pencil to be sharpened, and Fig. 7 is a detail perspective view of the sharpening element or knife.

Referring to the drawings by reference-numerals, 1 designates a casing comprising a bottom 2 and side walls 3, which project upwardly from the bottom 2 in parallelism.

Pivotally arranged between the sides 3 andv supported thereby is a knife-carrier 4 and a pencil-support 5, which are so arranged as to be relatively adjusted.

6 designates a T-shaped bracket, provided with upwardly-projecting arms 7, provided with perforations 8, through which pivotpins 9 pass to pivotally mount the bracket in applied position on' the casing. The bracket is adapted to carry the support 5, which is grooved longitudinally, as at 9", for the reception of the end of the pencil to be sharpened. The knife-carrier 4 is provided with a longitudinal opening 10, having the side walls thereof provided with ways 11, and said carrier is adapted to be pivotally secured in applied position by the pivot-bolts 9, projecting into bearings 12, located in the edges thereof. The knife 13 is adapted to be mounted in the ways 11 for movement back and forth across the support 5, and said knife is provided with two cutting edges 14, whereby when one cutting edge is worn down the knife maybe easily reversed to bring into operation the other or unused cutting edge. The knife is provided with a handle 15, which projects upwardly above the carrier 4 and by means of which it may be reciprocated in the ways to sharpen a pencil. A block 16 is secured between the sides 3 adjacent their forward edges and be tween the bracket 6 and carrier 4. This block is provided with a longitudinal groove 17 arranged in alinement with the groove 9 whereby a pencil may be placed in the groove 17 to dispose its end to be sharpened in the groove 9".

The body of the pencil is adapted to be placed in the groove 17, so as to disposethe end of the pencil to be sharpened in the groove 9. Thus placing the pencil will present the end of the pencil in a path of the movement of the knife 13, and by moving the knife and turning the pencil the pencil may be successfully sharpened without breaking the lead.

The groove 9 is conical or tapers rearwardly, as disclosed in Figs. 4 and 6 of the drawings, so as to regulate the amount of wood to be cut from about the lead of the pencil in a manner that is apparent to those skilled in the art.

In order to provide for the adjustment of the carrier 4 and the bracket 6, an adjustingscrew is mounted on the block 16, and so connected to the knife-carrier and bracket that the turning of the adjusting-screw will cause the knife and support 5 to either move from or toward each other. The forward end of the block 16 is provided with parallel-arranged ears 19, between which the adjustingscrew 18 is mounted for rotary movement.

The carrier 4 has its forward end providedwith a horizontally-disposed flange 20, with which theupper end of the adjusting-screw has connection, and the forward end of the bracket 6 is also provided with a flange 21, with which the lower end of the adjustingscrew has connection.

It is apparent from the above description, taken. in connection with the accompanying drawings, that by turning the adjustingscrew one way or the other the carrier and bracket are turned upon their pivots, so as to cause the guide and knife to either approach or recede from each other, whereby the knifesharpener may be adjusted so as to accommodate for pencils of varying diameter.

From the foregoing description, taken in connection with the accompanying drawings, the construction and mode of operation of the invention will be understood without a further extended description.

Changes in the form, proportions, and minor details of construction may be made within the scope of the invention without departing from the spirit or sacrificing any of the advantages thereof.

Having thus fully described the invention, what is claimed as new is- 1. In a pencil-sharpener, a swinging sup port for the end of the pencil to be sharpened, a swinging knife-carrier having a cutter movably mounted thereon, and means for simultaneously swinging both the support and the knife-carrier to move each toward and from the other.

2. In a pencil-sharpener, a swinging support for the end of the pencil to be sharpened, a swinging knife-carrier, said support and carrier having a common pivotal connection, and means for swinging said support and carsoaees rier to simultaneously adjust the same toward and from each other.

8. In a pencil-sharpener, a casing, a block carried by said casing and provided with a groove, a bracket pivotally secured in said casing, a support carried by said bracket and provided with a groove, apivoted knife-carrier, a knife movable thereon, and an adj ustmg-screw carried by said block and having connection with the knife-carrier and bracket, whereby the knife-carrier and support are adapted for simultaneous adjustment toward and away from each other.

4. In a pencil-sharpener, the combination of a casing or frame, a stationary rest-block thereby to support the body of a pencil, a pivoted support for the end of the pencil to be sharpened, a pivoted knife-carrier, and an adjusting device carried by said stationary rest-block and engaging the swinging support and carrier, whereby the same may be simultaneously adjusted toward and from each other.

5. In a pencil-sharpener, a casing, a block carried by said casing and provided with a groove, a T-shaped bracket provided with arms, a support carried by said bracket and
