Description

RUDOLF THEIS, OF SOLINGEN, GERMANY.
SCISSORS.
Specification of Letters Patent.
Patented J an. 9, 1906.
Application filed January 6, 1905. Serial No. 239,896-
To all whom it may concern:
Be it known that I, RUDOLE THEIs, a subject of the German Emperor, residing at Solingen, Germany, have invented new and useful Improvements in Scissors, of which the following is a specification.
This invention relates to improved scissors which are so constructed that the cutting edges of the blades are spring-pressed against each other in a novel and effective manner to obtain a superior cutting action.
In the accompanying drawings, Figure 1, is a front view of a pair of scissors embodying my invention, and Fig. 2 a longitudinal section of Fig. 1.
The lettersA and B represent, respectively, the upper and lower cutting members of a pair of scissors or shears turning on a pintle a. Back of the pintle the upper member A is perforated for the reception of a ball or similar body I), which thus rests back of the pintle upon the lower member B. Upon the ball I) bears the rear end of a spring 0, which is forked at its front end to grasp the upper reduced neck a of the pintle a and is perforated atits rear end, as at c, to engage ball I).
' Beyond the perforation c the spring 0 may be rearwardly extended to form a finger-piece c Forwardly the spring 0 extends beyond the pintle a to bear upon the outer side of member A in front of the pintle.
It will be seen that the rear of the spring by acting upon the inner side of member B back of the pintle through the intervention of the ball I) forces the cutting edge of such member upward. The front of the spring tends to draw the pintle upward and at the same time by bearing upon the upper memher A in front of the pintle forces the cutting edge of such member downward. In this way the cutting edges of the members A B are forced against each other to prevent looseness and produce a superior cutting action.
What I claim is I Scissors provided with a pair of pivoted cutting members of which the first member is perforated back of the pivot, a spring engaging the pivot and extending forwardly and backwardly thereof, the front of the spring bearing directly upon the outer side of the first member in front of the pivot, and the back of the spring bearing upon the inner side of the second member back of the pivot, whereby the cutting edges of the members are forced against each other, substantially as specified.
Signed by me at Solingen, Germany, this 24th day of December, 1904.
BUD. THEIS.
