IMPROVED HAN D-SHEARS.

Specification forming part of Letters Patent No. 45,659, dated December 27, 1864.

.T0 all whom it may concern.'

Be it known that I, JOHN N. VALLIS, of the town of Fleming, in the county of Cayuga, in the State of New York, have made a new and useful Improvement in Hand Shears or Ni ppers, and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the aecompanying drawings, and to the letters of reference marked thereon.

The object of this invention consists in the peculiar arrangement ot' the several parts, to the end that less power or force shall be required to operate the saine than in any here tofore in use.

Figure lis a plan of said shears. Fig. 2 is an edge view. Fig. 3 shows the opposite side from that shown in Fig. l.

In Fig. l, A is one ofthe front levers. B is the other. O and D are the two rear levers. To the levers A and B are secured pieces of steel, E and F, which forin the cutting edges. The opposite ends ot' said levers are curved inward. 'lhe curved pieces G on the lever A, and the piece H of like form on the rear end ofthe lever B, have slots I and J in each, and said pieces are secured to each of the said levers by means of screws. rlhe levers G and D are jointed to the levers A and B at K and L. The curved pieces G and H have a slot in the rear end of each, into which the studs M and N are secured. Said studs as the5T pass through the slots ,enter into and secure the curved pieces H aud G to the lever C and D. Underneath each of said curved pieces G- and H are pulleys O and I), having their eenters at Q. and It. The slotsin the rear end of the plates G and H serve to hold the pulleys O and I) close against thetwo inclined planes S and T on the inside of the levers C and D.

And now it will be observed that whenever the rear end of the levers C and D are pulled apart the cutting-edges will be opened, and when made to approach each other the euttin ged ges will approach.

Having described the inode of constructing and opera'ing my invention, what I wish to secure by Letters Patent is- The friction pulleys O and P, working against thelevers G and D, in combination with the slots I and J, or their equivalents, as set forth.

JOHN N. VALLIS.
