Year: 1872

page_text: LETTERS PATENT to Isaac Fenno and Patrick Howe, both of
Boston, in the County of Suffolk, and State of Massachusetts, in
the U. S. of America, for the Invention of "IMPROVEMENTS ON
COMPLETE SPECIFICATION filed by the said Isaac Fenno and Patrick
Howe at the Office of the Commissioners of Patents, with their
Petition and Declaration, on the 21st June, 1872, pursuant to the
9th Section of the Patent Law Amendment Act, 1852.
TO ALL TO WHOM THESE PRESENTS SHALL COME, we, ISAAC
FENNO and PATRICK HOWE, both of Boston, in the County of Suffolk,
and State of Massachusetts, in the United States of America, send
greeting.
WHEREAS we are in possession of an Invention for "IMPROVEMENTS
ON MACHINES FOR CUTTING CLOTH OR OTHER TEXTILE AND FIBROUS MATERIALS,"

page_text: The cutter shaft p is supported and made to revolve in a bored out
sleeve 8, provided with a hub t that fits over the lower end of the
sleeve n, around which it may swing in a complete circle, as indicated
by dotted lines on Fig. 1. A small set screw u is screwed through
the hub t and projects in a circular groove made on the sleeve n, by
which arrangement the hub t is connected to the sleeve n at the same
time as it is allowed to swing around it. A suitable handle v is
attached to the sleeves, by which the operator can guide the cutter
in an easy manner. To the extreme end of the cutter shaft p is
secured the revolving cutter w in a suitable way. The motive power
from the shaft d is conducted in the following manner:-
-On the
upper end of the shaft d is secured a belt or cord pulley x, as shown,
from which an endless belt or cord 1 is carried over the pulley y that
is made to run loose around the upper end of the hinge pin m. On the
top of the pulley y is a similar one z made in one piece with the
pulley y, over which an endless belt or cord 2 is carried to the pulley 3
keyed on to the upper end of the shaft o, as shown.
8
By the arrangement of the pulleys x, y, z, 3, and the endless belts or
cords running over them we are able to swing the arms i, l, in any
desired direction, either around the shaft d or half way round the hinge
pin m, without preventing the belts or cords 1, 2, from working equally
as well in all positions of the arms i, l, as the distances from the centres
of the pulleys x, y, and z, 3, remain the same in all positions of the
arms i, l. To the extreme outer end of the sleeve & is held an adjustable
foot piece 4 provided with a foot 5, by which arrangement the rotary
cutter is prevented from cutting the table 6 during the operation
of the machine. The foot piece 4 has a slot hole 6 in its upper end,
through which the set screw 7 is screwed into the sleeve 8, as shown
in Fig. 3, whereby the plate 5 may be raised and adjusted as the rotary
cutter w wears off by continued sharpening. A small incision may be
made in the upper side of the foot 5 to serve as a guide for the cutting
wheel wo.

page_text: the movable arms i, l, and 8, are made to swing, for the purpose and in
a manner as herein shown.
In witness whereof, we, the said Isaac Fenno and Patrick Howe,
have hereunto set our hands and seals, this Fourth (4th) day
of June, A.D. 1872, at Boston, Massachusetts, in the United
States of America.
Witness,
ISAAC FENNO. (L.S.) and PATRICK HOWE. (L.S.)
