WARREN R. BRIGGS, 0F STBATFGED, CONNECTICUT.
PENCIL SHARIJENER AND V'IPER.
Application filed January 26, 1926. Serial No. 83,738.
To all 107mm t may concern.'
Be it lrnown that Wannen R. Bine-as, a citizen of the United States, residing at the town of Stratford, in the county of Fairfield and State of Connecticut, have invented cetain new and useful limprovements in Pencil Sharpeners and liVipers; and l do declare the following to be a full, clear, and enact description of the invention, such as will enable others slrilied in thel art to which it appert-ains to malre and-use the same. Y
rhis invention relates to pencil sharpeners, but more particularly has reference to devices of this nature which are used to point or sharpen the lead element of a pencil by attrition along a suitable abrasive surface such as is readily provided by sandpaper.
Also the invention contemplates the provision of wipers kwithin which the pencil point after sharpening may be cleansed of the dust caused by the sharpening so that such dust cannot fall on a drawing oi' other surface whose cleanliness is desired.
The invention is inthe form of a low structure that is utilized on both sides and which is not at all likely to be upset and which rests on a table or drawing board convenient of access and readily shiftable to any desired location.
The accompanying drawings illustrate an approved embodiment of the invention and are to be read in connection with the de scription that follows, and similar numerals of reference denote like parts in the several figures ofthe drawing in which latter Figure l is a plan view of a pencil sharpener constructed in. accordance with this invention- Figure 2 isa side elevation- Figure 3 is a section at the line 3-3 of Figure 1, and
Figure lis a perspective view showing one end of the Sharpener properly assembled while the other end is shown in position preparatory to assembly, the sand paper being omitted.
l is an elongated support, preferably a metal plate, having at its opposite ends lugs 2 and at each of its lateral terminals a pair of ears 3 that are bent in opposite dii rections at right angles to said plate to form legs for the purpose hereinafter to be eX- plained.
4 are two cylindrical shaped spring members made of thin spring metal and of a width about equal to that of said plate, the biting edges o'f said members faciiw each other and embracing opposite ends of said plate, the lugs attending through openings 5 in the outer walls of said member and bent, as shown at Figures i). and El, to secure the plate to these members.
@n opposite sides of these openings 5 are slots o, and clamps i" extending throughout the width of the plate are positioned on opposite sides of the plate at each end, between the plate and the biting edges of the spring members sl-these clamps having :pinch levers 8 which diverge from the outer ends of the clamps and extend through the slot-s G.
Normally the resiliency of the spring members will bind these clamps firmly against the opposite faces of the plate with the levers S diverging, but when these levers are pinched together the clamps will be forced away from the plate against the resiliency of the spring members, as is shown at Figure t inthe instance of the clamping structure that is ready for assembly.
9 are the wipers, preferably made of felt or heavy fabric that is doubled, the closed end of each wiper being confined between an edge of the spring member and the outer face of a clamp, the free edges of the wipers diverging and extending beyond the edges of the clamps, as clearly shown.
Strips lO of sandpaper cut to suitable proportions are placed in position on the opposite faces of the plate by pinching the levers 8 and inserting the ends of said strips successively between the clamps and plate, the release of the levers causing these strips to be securely held in place. Y
lt will be noted that the wipers are no-t disturbed by the removal or insertion of Y these strips, since said wipers are confined between the edges of the springs and the top faces of the clamps, whereas the strips are in contact with the plate and the bottom faces of the clamps.
In assembling the parts o-f the device the clamps are first positioned between the edges of the springs, the jaws of the springs then forced away from the clamps, and the wipers inserted between said edges and the clamps. Thereafter, the levers 8 are pinched together, as shown at Figure et, and the lugs inserted through the openings 5 and bent down.
While it is preferred to form the ears to provide legs, and to possibly present a more pleasing design to the eye, nevertheless snch legs` are not necessary, since the cylindrical shapes of the spring members lend themselves as suitable supports for the device with either face uppermost and therefore the invention is not limited in this respeet.
lVhat is claimed is :M
l. A device of the character set iliorth, comprising cylindrical spring members having resilient edges laeing inwardly and having openings in their outer walls and slots on opposite sides o said openings, an abradant carrying plate positioned between said edges and having lugs extending through said openings and bent, clamps confined between said plate and edges and having diverging pinch levers extending` through said slots7 and wipers confined between said edges and clamps and projecting inwardly beyond said clamps.
Q. A pencil Sharpener and wiper, coniprising cylindrical end springs having re silient edges facing each other, an abradant carrying support secured at its ends to the outer walls ot said springs and extending between said edges, clamping ineinl'iers confined between said support and edges and haring diverging pinch levers that extend through said walls and 'lelt wipers extending inwardly beyond said clamps and contined between the latter and said edgs.
A construction as in claim l in which the lateral ends ol'l the abradant carrying plate are formed with pairs ot ears, the eats ot each pair being bent. at right angles to the plate and in opposite directions to eonstitnte legs.
In testimonyv whereof l allix my signature hereto.
VARREN R. BRIGGS.
