AMENDED COMPLETE SPECIFICATION.
Improved Machinery for Cutting Rags or other Fibrous Materials.
We, ANDREW MASSON and ROBERT SCOTT, Engineers, both of York Place,
Battersea, in the County of Surrey, 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:-
The
improved machine is intended to cut rags or other fibrous materials into
short squares or rough oblong pieces and consists of the following devices arranged
and.combined in the improved manner hereinafter described with reference to the
accompanying drawings:-viz.: a first-cutting apparatus and a second-cutting
apparatus both of the same peculiar construction herein-after described and
arranged at right-angles to each other, the second-cutting apparatus being driven
by a rope or the like directly from the first-cutting apparatus; first and second
travelling bands respectively feeding the fibrous material to the first-cutting
apparatus and from that to the second-cutting apparatus also arranged at right-
angles to each other and respectively driven by a belt and gearing from the
relative cutting apparatus; and a travelling band driven by a belt from the second-
cutting apparatus and adapted to carry the cut material to
The improved machine is shewn in detail on the accompanying drawings.

represented in the other figures.
.
:
Figure 2, represents an end elevation, omitting some of the details represented
in the other figures.
Figure 3, represents a plan, omitting some of the details represented in the other
figures.
The material to be cut is delivered by means of a feed-table A, and travelling
band B, to the first-cutting apparatus. The feed-table is supported by the machine-
frame, and 'the travelling band is carried by rollers 4, supported in suitable bearings,
and is driven from the main shaft 5, of the first-cutting apparatus by a belt P,
pulleys 6, 7, and gearing. W, 8, the pulley 6, being fast on the shaft 5, the pulley 7,
and gear wheel W, 'loose on a stud 9, supported by the machine-frame, and the gear-
wheel'8, fast on the spindle of the adjacent roller 4, vide Fig. 2.
The first-cutting apparatus (vide Figures 2, and 3,) comprises a feed-roll C, made
with bars or teeth on its circumference, and a doctor or scraper D, which removes
the rags from 'the travelling band B, and, together with feed-roll C, delivers them
to the cutting knives E, F. The doctor or scraper D, is suitably secured to the
machine-frame and presents one edge to the band B, and the other edge to that of
the knife E. The feed-roll 'C, is suspended on swing arms M, in such a manner
that it is free to rise or fall to accommodate the amount of rags which may be brought
forward by the band B. The roll is mounted on a spindle 10, working in 'bearings
carried by the swing arms M, which are mounted on studs 11, supported by
extensions of the machine-frame. The roll is driven from the shaft 5,'by 'the
belt P, pulleys 6, 7, and gearing W, 12, 13, the gear-wheel 12, being loose on the

page_text: djacent stud 11, and the gear-wheel 13, fast on the spindle 10. The feed-roll
being thus mounted and actuated is, as aforesaid, free to rise and fall, while
emaining at all times in gear with its actuating details.
The cutting knife E, is stationary and is secured to a cross bar 16, in such a
nanner that by means of set-screws K, it can be set forward and adjusted as and
when required. The knife or knives F, F, (one or two of which can be used as
desired) is or are in like manner slotted as at 17, and bolted as at 18, to a drum or
roller G, fast on or made in one with the shaft 5, and can be set forward and
adjusted by means of set-screws 19, in the same manner as the knife E, above
described.
The shaft 5, is supported in bearings 20, carried by the machine-frame, and is
provided with fast and loose pulleys 21, 22, by the former of which it is driven
by any convenient motive agent. 23, represents a guard-plate covering the
cutting apparatus.
After the rags have passed between the knives E, F, they are received upon a
second travelling band B*, and by it they are delivered end ways to the second-
cutting apparatus, consisting of or comprising a scraper Dx, feed-roll Cx, and
knives Ex, and F*.
The second-feeding device B*, and its accessories consist of a similar and
similarly actuated arrangement and combination of devices to those hereinbefore
described with reference to the first-feeding device B, and its accessories, and on
the accompanying drawings like parts in both such first-feeding and second-
feeding arrangements (which, as aforesaid, are arranged at right-angles to each
other) are marked by the same reference numeral, those in the feeding device
intermediate of the first-cutting apparatus and second-cutting apparatus (which
device is, as aforesaid, actuated from the knife-shaft 5*, of the latter apparatus)
being distinguished by an added X.
The second-cutting apparatus (vide Figs. 1, and 3,) is made regarding details
and its means of actuation, and is, as regards its method of operation, precisely the
same as the first-cutting apparatus, but is placed so as to cut the rags in a direction
at right-angles to the direction of the first cut.
On the accompanying drawings like parts in the first-cutting apparatus and
second-cutting apparatus are marked with the same reference numeral, those in the
second-cutting apparatus being distinguished by an added X.
The rags are thus cut into square or oblong pieces.
The rags, after being passed through the second-cutting apparatus, are received
upon the travelling band S, and can be delivered to any desired point. The
band S, is supported by suitably arranged rollers 24, and, as aforesaid, is driven
from the shaft 5*, of the second-cutting apparatus by a belt 25, connecting
pulleys 26, 27, respectively fast on the shafts 5*, 28.
The driving of the various parts of the machine is accomplished by means of a
rope or driving band X, which, as aforesaid, conveys the power from the first-
cutting apparatus to the second-cutting apparatus, the rope being guided by
suitably supported pulleys 29, and connecting pulleys O, T, respectively fast on the
shafts 5, 5, and of the bands or belts P, Px, and gearing wheels W, W, and other
connected gearing hereinbefore more particularly referred to, which drive the first
and second feed-bands B, BX, and feed-rolls C, Cx, from the relative cutting apparatus
as shewn in the drawings.
By regulating the relative diameters of the driving pulleys O, T, the first-
cutting apparatus and the second-cutting apparatus may be driven at the same or
at different speeds and the rags or materials can be cut to any desired length and
square or oblong as desired.
Having now particularly described and ascertained the nature of our said
invention, and in what manner the same is to be performed, we declare that
what we claim is :-
1st. The improved machine consisting of the several specified devices arranged

page_text: and combined in the improved manner substantially as described above with
reference to the accompanying drawings.
2nd. The special combination of the details of the several feed-bands, scrapers,
feed-rolls and cutting knives as described above and shewn on the accompanying
drawings.
