Improvements in Cutting Pliers or Nippers.
A communication from abroad by GEORGE E. PARKER, of No. 259, A Street,
Boston, in the State of Massachusetts, one of the United States of America,
Manufacturer.
I, ADOLPH RIEKMANN, of 4, Huggin Lane, Queen Victoria Street, in the City
of London, Merchant, 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:-
This invention relates to that class of nippers or pliers having cutting
edges used for severing wire and other articles; one such use being the sever-
ance when required of the fasteners used in securing buttons to the fabric of
boots, shoes and the like.
DESCRIPTION OF THE DRAWINGS.
Fig. 1 is a front view of a pair of cutting pliers, or nippers, according to the
invention.
Fig. 2 is an edge view thereof.
Figs. 3 and 4 show separately, the two limbs A and B of Fig. 1, with the
removable cutting jaws and their binding screws, separated and shewn in
juxtaposition.
Fig. 5 shows a plan view of these cutting jaws and their binding screws in
their fixed position on the head of the pliers.
Fig. 6 is a similar plan view of one of such removable jaws separately.
The exemplification of the improved construction of cutting pliers or nippers
adopted for illustration is of a single jointed simple character, but the inven-
tion is obviously applicable to modified forms of such appliances.
A, B are the two crossed members of the pair of pliers, held in correct rela-
tive position with capability of a limited extent of motion or rocking by the
several stop parts 1, 2, 3, 4, 5, 6 and the pivot screw C. The removable jaws a, b
are secured respectively in the slots or recesses a, b of the heads of the mem-
bers A, B, by the screws a², 62 engaged in threaded holes provided for them
therein. These removable and renewable jaws a, b are very rigidly and securely
held in place against thrusts in use by the angular forms of the slots and the
cutting edges a³, are made of any convenient angle. The release of the
contact of the cutting jaws from a cut article, or from each other is effected by
the spring which is partially embedded in a hole in each opposed surface of
the members A, B at d d.
The nearness of approach of the cutting edges of the jaws a, b can be regulated
and adjusted by means of the regulating screw E which being threaded into
a hole in the member A at e can be caused to protrude more or less from the
surface of that member so as to make earlier, or later contact with the like sur-
face of the opposed member and so act as a stop to the further approach of the
cutting jaws.

page_text: By these means the life of a pair of cutting pliers may be indefinitely pro-
longed as any fracture, or injury to the cutting edges can be immediately recti-
fied by removal of a damaged jaw and the substitution of a new one, and spare
cutting jaws can be supplied with the lever parts. The temper given to these
small separable jaws can also be more readily controlled in manufacture and
greater uniformity secured.
Having now particularly described and ascertained the nature of the said in-
vention, and in what manner the same to be performed, I declare that what
I claim is:-
1. The improvements in cutting pliers, or nippers, having removable and re-
newable cutting edges, or cutting jaws, and means of adjustment, substantially
as described, and shown by the drawings.
2. The construction and use of a pair of pliers, or nippers, provided with a
pair of removable cutting parts, or jaws secured each to the opposite member
of the tool by a suitable holding recess and screw, as set forth.
3. The improved construction of cutting pliers, or nippers; with removable
cutting parts of the opposed jaws, each part secured to its jaws by a recess and
screw; with means for adjusting and regulating the extent of approach of one
cutting edge to the other and a spring to aid release thereof, substantially as
and for the purpose set forth and shown by the drawings.
4. The construction and use of cutting pliers or nippers having irremovable
cutting parts, means of adjustment of extent of approach of said parts and a
spring to aid release after cutting all as and for the purpose set forth.
