Improvements in Scissors.
We, FRIEDRICH WILHELM OSTERMANN, of 27, Leadenhall Street, in the
City of London, Commission Agent, and MICHAEL WORNUM BEAZELEY, of
194, Clapham Road, Lambeth, in the County of London, Schoolmaster, do hereby
declare the nature of this invention to be as follows:-
Our invention has for its object to provide improved means for causing the
blades of scissors to move slightly longitudinally relatively with one another when.
in use so as to obtain a shearing cut.
According to our invention the pivot is in the form of a stud attached to one.
blade and having gear teeth upon a part of its periphery. The other blade is
provided with a longitudinal slot which fits over the pivot and has upon one side.
teeth which engage with the teeth of the stud in such a manner that when the
blades are moved relatively with one another upon the pivot the desired longitudinal
movement will also be obtained.
Instead of fixing the stud to one blade we may make the stud loose and form a.
slot with teeth in each blade.

We, FRIEDRICH WILHELM OSTERMANN, of 27, Leadenhall Street, in the-
City of London, Commission Agent, and MICHAEL WORNUM BEAZELEY, of
194, Clapham Road, Lambeth, in the County of London, Schoolmaster, do hereby
declare the nature of this invention and in what manner the same is to be
performed, to be particularly described and ascertained in and by the following.
statement:-
Our invention has for its object to provide improved means for causing the blades.
of scissors to move slightly longitudinally relatively with one another when in use
so as to obtain a shearing cut.
According to our invention the pivot is in the form of a stud attached to one
blade and having gear teeth upon a part of its periphery. The other blade is
provided with a longitudinal alot which fits over the pivot and has upon one side
teeth which engage with the teeth of the pivot in such a manner that when the
blades are moved relatively with one another upon the pivot the desired longitudinal
movement will also be obtained.
To enable our invention to be fully understood we will describe the same by
reference to the accompanying drawing, in which :-
Figure 1 is a view of a pair of scissors having our improvements applied thereto,.
a part being removed to shew the pivot stud:
Figure 2 is a section on the line 2-2 of Figure 1

page_text: a and b are the two blades of the scissors and c is the toothed stud or pinion
forming the pivot and passing through the slot c' of the blade b. The stud c is
attached to the blade a by means of a screw d which screws through the stud and
is locked in position by a nute countersunk in the back of the blade a, the stud
being prevented from turning on the blade a by its shank being formed square
and entering a square hole in the said blade. e¹ is a washer which bears against
the upper surface of the stud c and overlaps the sides of the slot c¹, thereby
connecting the two blades together.
fare the teeth on one side of the slot c¹ with which the teeth of the stud or
pinion c engage.
It will be obvious that' when the blades of the scissors are moved relatively
with one another upon the stud c as a pivot, the said blades will have a slight
longitudinal movement as hereinbefore described.
Instead of fixing the stud to one blade, we sometimes make the stud loose and
form a slot with teeth in each blade.
Having now particularly described and ascertained the nature of our said inven-
tion and in what manner the same is to be performed, we declare that what we
claim is :-
1. Scissors the blades of which are pivoted substantially as described.
2. The manufacture and use of the improved scissors hereinbefore described and
illustrated in the accompanying drawing.
