EDWARD L. MODIVITT, OF BELVIDERE, ILLINOIS.
PENCIL SHARPENER.
srncxrrcn'rron forming part of Letters lPatent No. 700,071, da d y 1902- Application filed December 2,1901. Serial No. 84,493. (No model.)
To all whom it may concern:
Be it known that I, EDWARD L. MoDrvrrr,
a citizen of the United States, residing at'Belvidere, in the county of Boone and State of Illinois, have invented certain new and useful.
Improvements in Pencil-Sharpeners, of which the following is a specification.
This invention relates to improvements in pencil-sharpeners in which the pencil is held' in place by a spring and the point of the pencil located in a recess and a stop to the point.
In the accompanying drawings, Figure 1 is a perspective view of my improved pencilsharpener. Fig. 2 is a face view'of the same. Fig. 3 is a rear view. Fig. 4 is a side elevation. Fig. 5 is a lengthwise central section. Fig. 6 is a transverse section on dotted line a, Fig. 2. I
A plate 1, forming the main support for the pencil, is formed from sheet material and has its upper end 2 bent at an angle to the face and. provided with an opening 3. The face has a lengthwise openingt and a smaller open- 1ng o. M
A bridge 6 is located at the lower end of the opening 4, being insemicircular form and having an opening 7. The edges 8 of this bridge are undercut and fit corresponding projections extending-from the sides of the opening 4. The upper-face of this bridge has a recess 9, conical in form.
A plate-spring 10 has an opening 11, the lower portion of the spring held in place between the bridge and front plate, as shown at Fig. 6. The upper portion of this plate-spring is curved away from the rear face of the plate 1, as shown at Fig. 4.
The lead-pencil is placed through the opening 3 in the end 2, under the spring 10, and
in the conical recess. The knife 12 is drawn down the face of the plate 1, thereby severing a shaving from the pencil. The pencil is parshaving removed,
and so on until the leadent'ersandpasses through the opening 7 and rests against the end of the lower opening 5, asshown in Fig. 5. The angle'of the face of the plate 1 with respect to the lengthwise direction of the pencil is such as to give the sharpened end of the 'I'claim'a's my invention- 1. A pencil-sharpener comprising a sheetmetal plate provided with a lengthwise opening and'a'perforated end bent substantially at right angles to the face of the'plate and a bridge with aperipheral opening located across-the opening in the plate.
Y 2. Apencil-sharpener' comprising a sheetmetal plate provided with a lengthwise opening, a bridge with a peripheral, opening located across the opening in the plate leaving a portion of the lengthwise opening-each side of thelbridge, and a spring secured to the back of the plate.
3. A'pen'cil-sharpener comprising a plate with a lengthwise opening and an end provided with an opening, a bridge located across the lengthwise opening and having a conical recess and a peripheral opening.
4." A pencil-sharpener comprising a sheetmetal plate provided with a lengthwise opening, a bridge with a peripheral opening located across the opening. in the plate and a plate-springsecured to the back of the-plate and held in place by the bridge.
5. A pencil-sharpener comprising a sheetmetal plate provided with a lengthwise open ing, a bridge with a peripheral opening located across the opening in the plate, and a plate-spring with a lengthwise opening se cured to the back of the plate and held in plac'e by the bridge.
