andl thus well adapted to sustain the strain
placed thereon by the rear end of the screw.
An adjustment as above described I have
found both powerful, economical, and practi-
5 cal, and possessing many advantages, as ease
of operation, durability, &c.
It will be observed that as the levers 22 are
operated also are the pins 26 moved accord-
ingly, and by means of the pointer 28 the de-
ro gree of pressure of the rolls may be indi-
cated.
Having described my invention, what I
I claim is-
1. The combination, with the frames and
r5 boxes, a pair of which is movably mounted
therein, of a pair of rolls, the shafts of which
are journaled in the boxes, a pair of levers
pivotally connected at corresponding ends of
the frames, a threaded shaft passed through
20 openings in the overlapping inner ends of the
levers, a bearing-block for the inner end of
the shaft, a hub or nut having a handle at
the front end thereof, and connecting devices
between the levers and the movable boxes,
25 substantially as specified.
2. The combination, with the opposite stir-
rups, the opposite pairs of boxes mounted
therein, and the opposite rolls mounted in the
boxes, of the transverse yoke secured to the
30 front ends of the stirrups and terminating at
its ends in perforated bearing-ears, a pair of
curved levers pivoted at their outer ends be-
tween the ears, overlapping each other at their
inner ends and provided at said ends with
35 enlarged perforations, a screw-threaded shaft
mounted in the perforations and bearing upon
the yoke, and a nut having a handle mounted
thereon adapted for operating said nut, sub-
stantially as specified.3. The combination, with the stirrups, the 40
pairs of opposite boxes, and the two rolls jour-
naled therein, one of said stirrups being pro-
vided with a scale, of a pair of levers pivoted
at their outer ends upon the front ends of the
stirrups and terminating at their inner over- 45
lapped ends in enlarged perforated heads, a
screw-threaded shaft mounted in the perfo-
rated heads, pins connecting the levers with
the front pair of boxes, which latter are mov-
able, and a collar mounted on one of the pins 5o
and having a pointer moving over the scale,
substantially as specified.
4. The combination, with the opposite stir-
rups, the opposite pair of boxes, one of which
is movable, and the pair of opposite rolls hav- 55
ing their shafts journaled in the boxes, the
front pair of boxes being provided with sock-
ets, of a transverse yoke bolted to the front
ends of the stirrups terminating at its ends
in forwardly-disposed pairs of perforated ears 6o
and provided upon its inner sides within the
stirrups with transverse stops, a truss termi-
nating against the stops and bolted to the
yoke, a pair of curved levers pivoted ait their
outer ends between the ears and having their 65
inner ends overlapping and perforated, the
pins connected with the levers and terminat-
ing in the sockets of the boxes, and the nut
having a handle for operating upon said shaft,
substantially as specified. 70
In testimony that I claim the foregoing as
my own I have hereto affixed my signature in
presence of two witnesses.
