JOSEPII G. GOLDTHIWAITE, OF GALVESTON, TEXAS, ASSIGNOR TO THE
REMIBERT ROLLER COMPRESS COMPANY, OF SAME PLACE.
ADJUSTING DEVICE FOR COMPRESSING-ROLLS.
SPECIFICATION forming part of Letters Patent No. 454,402, dated June 16, 1891.
Application filed March 21, 1891, Serial No. 385,863. (No model.)To cll whoi it n7cy concern:
Be it known that I, JOSEPH G. GOLD-
THWAITE, a citizen of the United States, re-
siding at Galveston, in the county of Galves-
5 ton and State of Texas, have invented a new
and useful Adjusting Device for Compress-
ing-Rolls, of which the following is a specifi-
cation.
This invention relates to adjusting devices
0o for that class of compressing-rolls employed
for compressing into a continuous thin sheet
cotton fiber; and the objects in view are to
provide a simple and convenient means for
binding the rolls in contact, and when so
15 bound to prevent any undesired yielding.
Other objects and advantages of the inven-
tion will appear in the following description,
and the novel features thereof will be par-
ticularly pointed out in the claims.
20 Referring to the drawings, Figure 1 is a
plan of a pairof rolls and means constructed
in accordance with my invention for binding
the same in contact. Fig. 2 is a horizontal
section of one corner of the roll-supporting
25 stirrup or frame, a roll, and the binding mech-
anism. Fig. 3 is a side elevation. Fig. 4 is
a detail in plan of the yoke. Fig. 5 is a de-
tail in section of the yoke.
Like numerals of reference indicate like
30 parts in all the figures of the drawings.
1 designates a pair of opposite frames or
stirrups, the rear ends of which are curved
or semicircular in shape, as shown at 2. In
each of the stirrups is mounted a pair of
35 boxes 3 and 4, the latter being at the rear ends
of the stirrups and curved, as at 5, at their
rear ends to correspond with the curvature of
the stirrups, while the former are provided at
their front sides with sockets 6. Each box
40 has a bearing-opening 7, to which oil is fed
by oil-cups 8, and in each pair of opposite
bearings are mounted the trunnions or shafts
9 of a pair of metal rolls 10.
Securely bolted to the front ends of the
45 stirrups is a transverse yoke-bar 11, the ex-
tremities of which occur slightly beyond the
stirrups and are provided with perforated
bearing-ears 12. Perforations 13 are formed
near the ends of the yoke and through the
50 same pass bolts 14 into the stirrups. The
yoke is braced by a truss 15, located at theinner side of the same and having its ends
abutting against transversely-disposed stops
or ribs 16, located upon the inner side of the
yoke, to which latter it is riveted, as at 17. 55
A bearing-block 18 is interposed between the
center of the yoke and truss, and upon the
same bears the inner end of a screw-threaded
shaft 19, upon which is mounted a threaded
nut or hub 24, having a hand-wheel or operat- 60
ing-bars 20.
Pivoted between the perforated lugs or ears
12 at the ends of the yoke, by means of a bolt
21, is a pair of inwardly-disposed curved le-
vers 22, terminating at their inner ends in 65
overlapping perforated heads 23, which loosely
receive the screw-threaded shaft 19, and the
outer one of which is borne upon by the hub
or head 24, formed at the outer end of the
threaded shaft 19. Through perforations 25 70
formed in the front ends of the stirrups is
passed a pair of rearwardly-disposed bars or
pins 20, the rear ends of which terminate and
bear in the sockets 6 of the front pair of
boxes 7. 75
A collar 27 is located upon one of the pins
or bars 26, is screw-threaded to receive the
same, and carries an indicating finger or
pointer 28, designed to move over a scale 29
upon the edge of the adjacent stirrup. So
The operation of the above device will be
readily understood from the foregoing de-
scription, and may be briefly explained, as
follows: It is necessary to have the rolls 10
run in contact their entire length, and to be 85
supported in such contact against any back
pressure caused by the substance or material
passing therethrough, so that said material is
formed into a thin continuous sheet or web.
It will be observed that by operating the 90
hand-wheel or handle 20 the hub or nut is
rotated and the adjusting-levers 22 are forced
in or relaxed in accordance with the direction
of rotation of the hub or nut, and in this man-
ner are the pins 26 either employed for fore- 95
ing the rolls together or easing the same, as
may be necessary. It will be observed that
an immense pressure may be thus secured
with but little exertion, and that when ob-
tained the rolls will be maintained against 0oo
anyback-pressure and heldimmovableagainst
separation. The yoke is strongly trussed,
