FREDERICK O. PAIGE, OF DETROIT, MICHIGAN.
COMBINED PAPER-WEIGHT AND ENVELOPE-CUTTER.
SPECIFICATION forming part of Letters Patent No. 460,756, dated October 6, 1891.
Application filed June Z6, 1891. Serial No. 397,618. (No model.)
T0 all whom t may concern:
Be it known that I, FREDERICK O. PAIGE, a citizen of the United States, residing at Detroit, in the county of I/Vayne and State of Michigan, have invented a new and useful Improvement in a Combined Paper-Veight and Envelope-Cutter, of which the following is a specification.
Figu rel is a perspective view cf my invention. Fig. 2 is a section on line a: a3, Fig. l.
The purpose of my invention is to provide an envelope cutter or opener that shall at the saine time serve as a convenient paper-weight, and that shall as an en velope-o pen er be adapted to cut the end or side of an envelope just enough to open the same without cutting the contents.
In' the drawings, A is a solid block, preferably made of metal, and of sufficient weight. to make a suitable paper-weight and at the same time give stability to the Whole device when used as an envelope-opener.
B is a stationary cutter attached to the block A by the screws h and h. ary cutter B has at each end an offset portion b2 abutted against the steel block, so as to leave the opening B between this cutter and the block in which it is pivoted the paper cutter or knife C. This knife, which, like the other parts, I make of cast or forged steel, is of just sufficient thickness to lill the space B and is provided with a cutting-edge on the outer side to act in conjunction with the inner edge of the stationary blade B to form a paper-cutter, and is provided with a suitable handle c and preferably at the outer end with an inclined portion c to form a continuous shearing-edge to the extreme outer end as the blade is depressed. This is desirable,
as the shearing engagement between the knife-edge on the blade C and the cutter B decreases as their point of engagement reaches the outer end.
It is manifest that if the knife be elevated andan envelope placed over the cutter B and abutted against the block A the depression This station-V of the knife will cut off from the envelope a piece of a Width equal to the thickness of the knife. The knife I provide of just suitable length that the blade or cutting-edge will come within the offset portion b2 of the stationary cutter B. The knife itself I pivot to the screw b, that holds the stationary cutter B to the block A.
The block A, I provide with any suitable handle, as A, forlifting the same when using it as a paper-weight.
rlhe device may be made of one solid block of steel by forming the stationary cutter B integral with the block A and providing the slot or opening B for the reception of the knife in the block itself, although I prefer the construction shown, as the stationary cutter B may be removed and sharpened.
l. In a combined paper-weight and envelope-cutter, a stationary blade and a movable blade hinged together and supported by a block parallel therewith and'risiug above the cutting-edge of said stationary blade, whereby said elevated portion of said block forms a stop for limiting the amount cut from the envelope, substantially as described.
2. In a combined paper-weight and envelope-cutter, the combnation'of block A, a stationary cutter hinged to said block 'and having its cuttingedge below the top of said block, and a movable cutter adapted to shear with said stationary cutter, said block A adapted to limit the amount cut from an envelope, substantially as described.
3. In a combined paper-weight and envelope-cutter, the combination of block A, stationary cutter B, and movable cutter C, arranged as shown and described.
In testimony whereof I sign this specification in the presence'of two witnesses.
FREDERICK C. PAIGE.
