Patented Oct. 17, 1916.
Application led November 24, 1913. Serial No. 802,702.
To all whom t may concerny Be it known that I, WILLIAM M. HALEY, a' citizen of the United States of America, and a resident of the city of St. Louis and State of Missouri, have invented certain new and usefulImprovements in' Pencil-Sharpeners, of which the following is a specification.
The primary object of this invention is to provide an improved pencil Sharpener whereby the pencil is sharpened by the hand Fig. 2 is a horizontal section taken on the line'II-II, Fig. 1. Fig. 3 is a horizontal section taken.y on the line III-III, Fig. 1.
Referring by numeralsto the accompanying drawings: 1 designates the base portion of this improved device. Formed vertically in said base portion is a bore 2. Normally seated in the upper portion of said bore`2 is the lower end 3 of a spiral shaft 4, said shaftA having the spiral groove 5V formed therein. This shaft 4 is held in its normal position by the helical spring 6 which is mounted in the bore 2. The lower end of said spring rests on the bottom of said bore and the upper end bears against a cupshaped washer 7. The top side of said washer has the depression 8 formed therein, said depression beingc for the reception of the rounded portion 9 of said shaft 4. Secured to the top of thebase portion 1 by screws l0 is a collar 11.07 Said collar has a lug 12 extending from the inner periphery thereof, said lug being engaged in the groove .5 of the spiral shaft 4. 'l
Formed on the upper end of the. shaft 4 is a stud 13. Mounted over said stud and bearing against the shaft 4 is a rubber bumper 14. Mounted on said stud 13 and bearing against the bumper 14 is a cutter head opening 16 formed'vtherein. Formed on said cutter head adjacent the lower end' thereof 1s an annular rib 17. Loosely mounted on said cutter head beneath said rib is a plate 18. Said plate 'is held in position by the collar 19 and is adapted to serve as a hand rest. Formed in said cutter head is a vertical opening 20 which communicates with a conical opening 16. Mounted in said opening 20 is a cutting blade 21.
This improved device is designed so it can serve as a paper weight as well as a pencil Sharpener. sharpen or re-point a pencil, the user merely inserts the end of the pencil .in the cutter head andfpresses downwardly on the pencil, the operation being as follows: The pressing down of the pencil against the cutter head causes the shaft 4 to be moved downwardly 1n the bore 2, and the lug 12 engaging-the groove 5 will cause the shaft to be revolved.
said cutter head will also be revolved, and the blade 21' will engage the pencil thereby sharpening the point thereof. When the pressure of -the hand is released from the l cutter head, the spring 6 will lift the shaft 4 to its normal position. The rubber bumper 22 carried by the lower end 3 of the shaft 4 will engage against the under side of the lug 12, thereby cushioning the shock of the vertical uplift of the shaft.. In order to relieve some of the pressure from the pencil as the shaft 4 is moved downwardly, the lower portion of the hand can be brought to bear on the plate 18. The rubber bumper 14 which is mounted on the upper end of the shaft 4 will engage against the collar 11, thus limiting the downward movement of the shaft.
What I claim is:
A pencil Sharpener comprising a spiral shaft, a cutter head secured to one end of said shaft, a pressure plate loosely mounted on said shaft, saidshaft adapted to be moved longitudinally, and means in engagement with said shaft for causing said shaft to lbe revolved when said shaft is moved longi-f tudinally by pressure on said shaft. t WILLIAM M. HALEY. y
In the presence of M. C, HAMMON, I-I. Gr. FIETCHER.
As the cutter head is secured to the shaft,
